The replacement of avacuum tube rectifier with a metallic. rectifier is sometimes desirablein various electronic instruments, such as rad ipreceivers, for example, because it permits instant starting. Thede'ticeot inyinvention is superior in other. ways to the usual, vacuum tube rectifiers ue t he p a ea at t strueii which-make t more new.

Fig.1 isa v rt ca 1on tu inals ec n e el y thr u h the embodiment Fig. 12, is across section along the line 2- 2,- of Fig. 1.
Fig. 3 is a top plan view of the embodiment partly cut away.
Referring with more particularity to the drawing in which like numerals designate like parts, the embodiment illustrated comprises an inner cylindrical cup H of porcelain or other suitable ceramic material coaxially disposed within an outer cylinder [2 of aluminum, copper, steel, or other suitable metal. The cup I I is used not only to house the internal electrical components, but to insulate them against short circuits and withstand the heat developed by the components.
The diameter of the cylinder i2 is substantially greater than that of the cup I I so as to provide a space l3 therebetween. The cylinder I2 is also provided with perforations M to freely admit circulating air, all of which contribute to the ability of the device to dissipate rapidly heat from the cup H.

The leads 33 and 34 are connected to the ends of a resistor 4|, and the terminals 35 and 36 are connected to the ends of a resistor 42. The function of one of the resistors, say resistor 4|, is to reduce line voltage, while the other resistor acts as a shunt to obtain the proper voltage for a pilot or julot lamp in a radio receiver, for example. Most radio rectifiers, for example, of the vacuum tube type include elements to provide for one or both of these functions. Accordingly, these resistors are an integral part of the device illustrated to render it an exact equivalent of the usual type of vacuum tube rectifier encountered in the radio field.
The resistors 4| and 42 are supported by threading each one through a pair of apertures 43 and 44, respectively, in the disc 22 before attaching them to their respective terminals in the base of the cup H. The leads 29, 30, 33, 35, 35, and 36 are connected to prong terminals 45, 46, 41, 48, 49, and 50, the latter being secured to and projecting from the bottom of the base member 17. Additional prong terminals and leads, such as the terminal 5i and lead 52 and corresponding aperture 53, may be provided for any additional element, or elements, desired in the device.
From the above description it may be seen that this invention embraces devices which are as convenient and simple to use as the ordinary vacuum tubes. By the use of proper materials the construction of these devices obviates dimculties heretofore encountered and results in a sturdy and long lasting unit. Rectifiers made in accordance with this invention can readily be substituted for the usual type of vacuum tube rectifier, and is superior thereto in many Ways.
