Field of application of the invention

The apparatus for discharging ozone-containing air is applicable to those extinguishing apparatus in which EPROMs are extinguished with ultraviolet rays as required in research, in the manufacture of microcomputers and users thereof, in cases where several of them are operated simultaneously Extinguishers a health hazard occurs.

Characteristic of the known state of the art

There is known an ultraviolet light extinguishing apparatus for carrying out the erasure of programmable erasable read-only memories (EPROM) (DE G11C17 / 00, No. 3,146,722 AD), wherein the erasure in one case is in-plane tubular and straight mercury Low-pressure lamps are arranged and that on both sides of this plane and extending parallel to the housing pull-out receptacles for the read-only memory are provided and that in the removal or insertion of the recording gestattenden area of the extinguishing device, a closure flap is arranged, which during the Extinguishing time is kept in locked state.

There is also known an erasing device (OE G11C 7/00, No. 36 22 394 A1) in which, in order to erase the memory contents of an EPROM in which the EPROM is exposed to UV rays, the erasure operation is interrupted between UV pulses and the respective memory contents the EPROM is queried, and after each polling operation, the erase operation is continued by means of UV pulses until complete erasure.

There is also already an erasing device (DE G11C17 / 00, no. 3619971A1) for erasing electrical semiconductor memory with a tubular UV radiation source, magazines for receiving the b. 'To radiating semiconductor memory, a housing closed on all sides, z. 8. made of plastic or metal and electrical installation for operating the radiation source, wherein to a mounted in a housing radiation source, the magazines located in the magazines semiconductor storage ir radiation with their irradiation windows in more than one irradiation plane concentric to the radiation source are extended and the magazines either from UV -permeable fluorescent tubes or of tubular plastic or metal with a UV-transparent longitudinal zone, have an outer shape of the semiconductor memory matched internal cross-section, in which the semiconductor memory can be inserted with its longitudinal axis in parallel or transverse to the longitudinal axis of the magazine and which is designed so that upon rotation, he magazines are secured around its longitudinal axis, the semiconductor memory against rotation and falling out.

As can be seen from the above, the development of erase devices has been such that the range of use of erase devices for erasing fixed value memory circuits (EPROMs) is becoming ever greater. The simultaneous operation of several fire extinguishers has the great disadvantage that the ozone content of the air rises sharply and leads to damage to the health of the processor.

Object of the invention

The aim of the invention is to prevent the harmful effects of the ozone-containing air on the processor when erasing EPROMs.

Explanation of the essence of the invention The causes of the indicated deficiencies are that ozone is generated by the JV-rays when erasing the EPROMs. Dio technical task of the invention is the ozone content of the air in the rooms in the extinguishing devices for Erasure of EPROMs with UV rays are decreasing. According to the invention, the device for reducing the ozone nuisance is that several extinguishing devices

stand directly next to each other, with on one side of a fan of air ducts with distributor to the individual

Extinguishing devices lead and are airtight connected to the extinguishing devices and on the other side of the

individual extinguishing devices Ozone pipes that are resistant to ozone and airtight at the individual extinguishing devices

are connected, the same are merged and discharged through an opening of the room in the open.

In operation, the blower blows air through the air ducts and flows through the air in parallel Extinguishing devices and presses the ozone contained in the extinguishing devices out of these through the ozone lines and

thus leads the ozone through an opening of the room to the outside.

In a variant of the device, a suction device is arranged. In a further variant of the invention, extinguishing devices with insertion drawers for assemblies equipped with EPROMs,

sincfdio air ducts and ozone pipes arranged behind the extinguisher.

In an advantageous embodiment, the extinguishing devices are next to each other airtight with quick fasteners and

compressed air-flow together serially, wherein at a first extinguishing device, a blower with air filter is arranged and leads from the last extinguishing device, the ozone line into the open air. The mounting plate of the ozone pipes has the same

Size as a side surface of the extinguishing device. The extinguishing devices have in the contacting side openings Recesses that are sealed with a rubber ring against the outside air. In another advantageous embodiment, the size of the first extinguishing device is adjusted in size. Air filter assembly is connected and attached to the last extinguishing device is a suction fan assembly to which

a leading to the outside ozone line is connected. The fan assembly is the same size as the

Extinguishing devices and is connected to the same with a quick release. In all mentioned variants of the parallel or serial air flow guide are the rubber seals, air ducts and

electrical lines are protected by built-in black colored shielding surfaces and the EPROM subassemblies drawers are sealed with UV-resistant rubber and provided with pressing quick-release fasteners and further the arrangement of the electrical devices on the back of the device, such as switches, fuses and cable plug is formed air-tight.

embodiments The invention will be explained in more detail below by way of example. The accompanying drawing shows in

Fig. 1: a schematic plan view of the device Fig. 2: a variant of the device Fig. 3: a variant of the device

As can be seen from Fig. Lersichtlich, the device is that several extinguishing devices 1 are immediately adjacent to each other, leading on the one hand of a fan 2 of air ducts 3 with distributor 4 to the individual extinguishing devices 1 and are airtight connected to the extinguishing devices 1 and on the other side / on the individual extinguishing devices 1 Ozonleitungcn 5, which are resistant to ozone and airtight connected to the individual extinguishing devices 1, wherein the same are brought together and discharged through an opening 6 of the room in the masonry in the open.

In effect, air is blown from the blower 2 through the air ducts 3 and flows through the individual extinguishing devices 1 and pushes the ozone contained in the extinguishing devices 1 out of them through the ozone line and thus introduces the ozone through an opening 6 of the room Free.

As can be seen from FIG. 2, in a variant of the invention, extinguishing devices 1 with front-mounted loading crates (11) are equipped with EPROM-equipped assemblies, the air conduits 3 and ozone conduits 5 are arranged behind the extinguishing device.

As can be seen from Figure 3, in an advantageous embodiment, the extinguishing device: n 1 next to each other hermetically clamped together with quick fasteners 12, wherein at a first extinguishing device 1, a fan 2 is arranged with air filter 13 and the last extinguishing device 1, the ozone lines 5 lead to the outside , The extinguishing devices 1 have in the contacting sides 7 recesses 8, which are sealed with a rubber 10 and the rubber seals 10 and electrical lines are protected by built-black shielding surfaces 9 and the container with the blower 2 has the same assembly as the extinguishing devices. 1 and is connected to the same with a snap closure 12 and the mounting plate 14 of the ozone lines 5 has the same size as a side surface 7 of the extinguishing device 1 and the EPROM assemblies receiving drawers 11 are sealed with UV-resistant rubber 10 and provided with quick-release and electrical Devices on the back of the device, such as switches, fuses and cable plugs are airtight.

The specific advantages of the invention are a substantial increase in occupational health and safety for the processors taking the erasure of the EPROMs.
