Title: Hydrodynamic working cylinder - incorporates sealing sleeve for working piston with gap between sleeve and cylinder
Inventor: NEMETZ JOSEF
IPC: F15B3/00
Filed: 1974-11-04
Abstract: In the working cylinder, the pressure transmission from pneumatic low pressure to hydraulic high pressure is effected via a pneumatically charged differential piston. The piston plunger, acting onto the fluid chamber of the fluid-charged working piston is guided sealed in a reaction pressure plate. The cylinder has a sealing sleeve, positioned in the path of the working piston, to surround it. There is a gap between sealing sleeve and cylinder, the end of which towards the reaction pressure plate is in open connection with the fluid chamber, the other end being sealed against the cylinder, and fastened to it, via a circumferential flange. Reaction pressure plate and sealing sleeve are integral, and the sleeve has apertures in the end facing the plate.

Title: Brick and tile elevator - has two pairs of chains with supports and driven separately from each other
Inventor: MIDDENDORF ALBERT
IPC: B65G49/08
Filed: 1974-11-19
Abstract: The elevator is particularly for handling tiles and bricks emerging from a press, having a pair of opposite endless chains, each with angle-section supports, two opposite supports on the chains engaging under the same tile etc. In addition to these chains (2, 5) there are a further pair of such chains, likewise with angle-section supports, driven separately from the first pair.

Title: Fail safe trailer air brake control - with dampened flow valve to balance pressures between vehicle and trailer circuits
Inventor: WANDERS DIETER DIPL ING
IPC: B60T15/36
Filed: 1975-10-09
Abstract: The supply line to the trailer brakes, in the air brake circuit, has a flow control valve. This balances the pressures in the towing unit circuit and in the trailer system. If a leak occurs in the trailer brakes the valve isolates the supply line and vents the trailer brakes to atmosphere. This applies the emergency brakes of the trailer. To provide a smooth emergency braking, without a sudden torque shock to the towing unit, the flow valve has a dampened valve element. This smoothes out sudden pressure changes and vents the trailer brakes in a control led manner. The emergency brake is then applied more smoothly.

Title: Negative gate voltage generating circuit - assists turn off in HF inverter thyristors with transformer primary in series with cathode
Inventor: SCHRAEDER ALFONS DIPL ING
IPC: H02M1/06
Filed: 1975-11-01
Abstract: The application is to high frequency inverters and has the object of decreasing the turn off time of the thyristor just commutated by applying a negative gate voltage. A current transformer (1) has its primary (11) in series with the thyristor cathode. Its secondary (12), connected in the opposite sense to the primary, is joined to the gate through a diode (10) a further diode (9) being connected in parallel with the secondary winding. A blocking diode (7) isolates the gate pulse supply (8). The transformer saturates, and is therefore ineffective, at high currents, but the small reverse current flowing at the end of the commutation period is detected and converted by the transformer into a negative gate bias to achieve the stated objective. Instead of the simple diodes a transistor switching circuit may be substituted, the current transformer the providing a power supply.

Title: Separation of krypton and xenon from crude oxygen - by taking fraction from base of medium pressure column
Inventor: JUNKER FRIEDRICH DIPL ING
IPC: F25J3/04
Filed: 1976-02-11
Abstract: The process is carried out in a medium pressure and low pressure column. The prod. stream contg. the Kr and Xe is washed in a vessel contg. rectifier trays with a Kr and Xe weak stream to give a liq. mixt. with an increased Kr and Xe content sepd. from gaseous O2 and N2. The Kr and Xe are sepd. from a fraction obtd. from the base of the medium pressure column. An Ar column is attached to the middle section of the low pressure column to recover additional Ar. The bottom stream from the Kr-Xe wash separator is used to provide the condenser cooling on the Ar column. The washing is carried out with a fraction taken several trays up the medium pressure column. The process is used to separate Kr and Xe from the crude O2 stream coming from an air sepn. process. Also it gives liq. O2 and a Kr-Xe rich stream avoiding problems of reliquification.

Title: HV cable with corrugated metal tape outer sheath - provides moisture seal without loss of flexibility and tape is welded longitudinally
Inventor: WERWITZKE LOTHAR
IPC: H01B7/20
Filed: 1976-05-06
Abstract: The HV cable, also for medium voltages, has a metal sheath covering the insulating outer semiconducting layer. The metal sheath has longitudinal corrugations formed by a thin metal tape seam welded longitudinally. The metal sheath is bonded to the outer sheath of the cable. The thin metal tape is first wound around the cable and seam welded. The corrugations are then made in it and finally the outer sheath attached. The corrugations are made by balls, rollers or wheels etc. pressing against the metal sheath. The advantage lies in providing a moisture seal without affecting flexibility.
