Title: Self cleaning gas filter with backflush - having rotary valve in backflush line to provide pulsing action
Inventor: GREGUTSCH MANFRED
IPC: B01D46/04
Filed: 1973-09-11
Abstract: Gas filter has envelope type filter bags with separator space and clean gas space. Clean gas is exhausted via fan(1) dirty gas enters line and dust collects in the hopper. The bags are cleaned by a backflushing action provided by moving nozzle(3). A supply of clean air/gas is given by fan(2) into a duct(4) connected to a rotary valve which has 3 branches. A second branch(5) connects to the backflush nozzle(5) while a third (6) connected to the clean gas space and thus to the suction of fan(1). As the valve rotates these various branches are interconnected. So far as nozzle(3) is concerned, it will be located on a bag which requires cleaning. When branch(5) is connected to branch(4) then a pressure is applied at nozzle(3) but when (5) is connected to (6), reaction is applied. When this happens in rapid succession a pulsing or vibrating effect is achieved on the bag and this causes the filter cake to fall down into the hopper. Any gas filtration application. Gives much more satisfactory operation than with flat valves where delay between pulses is too long to be of much effect, due to leakage between the two sides.

Title: Accurate mechanically operated automatic low pressure-regulator - depends on difference between atmospheric and controlled pressure to attain demanded pressure via a sprung valve
Inventor: MUELLER HERBERT
IPC: G05D16/10
Filed: 1974-01-25
Abstract: The simple but accurate low pressure automatic mechanically operated pressure regulator is for use with a vacuum pump attached to some device such as a low pressure cutting tool. The regulator is attached to the supply line running from the pump to the value, set up as a slot point with a hand lever and pointer mounted on a scale on the regulator itself. The principle of the device is simple and depends on a spring value element one side of which is open to the atmosphere via a number of vents, and the other side of which has access to the controlled pressure. The element travels up or down according to the difference between the atmospheric and controlled pressure force. If the element travels down- the pressure being too low- a vent is opened gradually to the atmosphere and allows the pressure to be increased from that source. A damping ring is also provided in the spring arrangements to prevent violent overshooting.
