Abstract
1304695 Mixing apparatus BAYER AG 14 Jan 1970 [23 Jan 1969] 1780/70 Heading B1C In apparatus especially for mixing polyurethane foam ingredients they are supplied through pressure-operated inlet valves 43, 44 to a mixing chamber 42, each inlet valve being provided with a device 45, 46 for actuating a timer 48 to indicate the interval between the opening of the valves. The devices 45, 46 may be pneumatic (see Fig. 1, not shown) mechanical, electrical or hydraulic; as described the opening of one valve starts, and of the other stops, the timer pointer (23), the direction of movement of the pointer indicating which valve is leading. There is a storage device 50, 51 in each supply pipe including a spring-biassed piston having an adjustable stop whereby the lead or lag of the valves may be compensated, and the adjustable stops may be controlled by the timer 48 through a pulse transmitter 49. By use of a suitable timer, the time of entry of more than two components may be synchronised.
