Title: Piston compressor cylinder - has cylinder valve(s) with regulator for cylinder throughput, with axially-movable element coaxial with valve
Inventor: FRENKEL MARK ISAAKOWITSCH

At least one cylinder valve has a conventional regulator for the cylinder throughput; the axially-movable element of the regulator is coaxial with the cylinder valve and fitted within it. Efficiency is increased by regulation of the compressor throughput w.r.t. the cylinder valve.
Patent DE-2400351-A1 (DE)
Title: Protective device for hot gas filter - being thermostatically controlled auxiliary fan giving bleed of clean cold air
Inventor: HOELTER HEINZ
IPC: B01D46/42
Filed: 1974-01-04
Abstract: A hot gas filter has an auxiliary fan and a damper controlled by a thermostat in a dirty gas stream. If the temp. exceeds a certain value, a fan and a damper are used to draw some additional cold air through the system to prevent overheating and consequent damage to the filter bags. Only a negligible amt. of excess load is placed on the filter, the extra air is clean and so no extra dust load is involved, and no reduction in the flow of dirty gas involved, since the hot gas fans can take a periodic increase in load to compensate for the reduced suction pressure reqd. Used for systems where hot dirty gases need to be filtered. Where cold gas bleeds are used to protect the filter cloth, this often results in depressed throughput from the equipment being exhausted. The use of an auxiliary fan avoids this, and although there is a slight reduction in filtration efficiency, the destruction of the filter cloth is avoided. The auxiliary fan has about 10% of the capacity of the main gas fan.

Title: Liq. ion exchange treatment appts - with automatic regeneration when resin contracts on exhaustion
Inventor: HESKETT DON EDWARD
IPC: B01J49/80
Filed: 1974-04-19

Title: Rotary kiln drive - entraining rollers driven by hydraulic motors with clutches and brakes ensure self-adjustment
Inventor: KOPPATZ RUDOLF
IPC: F27B7/22
Filed: 1974-10-02
Abstract: The design reduces the space requirements for the kiln drive as well as cost and the wear due to the individual low-velocity motors coupled directly to the rollers. The hydraulic motors are fed by a single source and the difference in diameters of the individual drive rollers (8) for rings of the kiln are readily compensated by the motors, while brake (26) controls the stoppage. The drive permits an easy setting of the position of salt or metal discharge spouts with the plate-type brake operated by a separated hydraulic line.
