Patent DE-2742652-A1 (DE)
Title: Pneumatic timer for differential piston pump - has larger face in chamber with inlet and larger outlet throttles
Inventor: KLOCKE HARALD
IPC: F15B21/12
Filed: 1977-09-22
Abstract: The pneumatic timer moves an actuator at regular intervals between the initial and working positions by supplying it with compressed air. Air pressure is directed onto the first and smaller face(A1) of a differential piston(4, 5) forming the actuator, bringing it into the initial position, and simultaneously part of the compressed air charges a chamber(8) via a throttle(9), the chamber being closed by a second and larger face(A2) of the piston. As pressure builds up in the chamber, this piston face if lifted off its seat towards the working position. This frees a third and larger face(A3) of the piston to exposure to the air pressure in the chamber, and moving the piston briskly into the working position.

Title: Pressed plastic plates stacking equipment - has movable support for transferring plates from tongues of carriage to stacking surface
Inventor: BANDERA LUIGI
IPC: B65G57/06
Filed: 1977-10-01
Abstract: The equipment for placing plastics plates on a stacking surface includes a reciprocating carriage (15) fitted at front end with tongues (16) for seizing and holding a plate. During advancing movement of the carriage (15), the plate is positioned on a movable support surface (23, 24). When the tongues (16) of the carriage (15) open the plate is released by the movable support surface (23, 24) and placed on the stacking surface. The movable support surface (23, 24) consists of an endless conveyor which is guided by wheels over the stacking surface. The carriage (15) is moving in the first part of its advancing movement at the same speed as the plastic band is pressed. In remaining part of its advancing movement, it is moving at a higher speed in order to create a cap between consecutive plates.

Title: Fixing irradiated nuclear fuel rod in can before storage - using binder of lime and filler contg. cpd. liberating carbon di:oxide on radiolysis or heating
Inventor: WEHMEIER JUERGEN DIPL ING DR
IPC: C04B28/10
Filed: 1977-10-07
Abstract: Spatial fixing of irradiated nuclear fuel rods in cans is effected by filling the space between the rod and the can with a binder and allowing this to harden. The binder used contains, in addn. to fillers and opt. water, quick-lime, slaked lime and/or partially slaked lime and organic and/or inorganic substances (I), which liberate CO2 and opt. water on radiolysis or heating. The process is used for preparing elements for storage before reprocessing. It prevents air attacking the fuel rod sheath and the rod itself, which could allows oxidised fuel particles to escape. Pref. (I) is a carboxylic acid or salt or an alkaline earth carbonate. The filler is sand. The binder is treated only with as much water as prevents the build-up of elevated water vapour pressure in the can.

Title: Fuel system for two-stroke engine - has piezoelectric regulator valve actuated by ignition dependent signals processed by comparator and pre-programmed integrator
Inventor: PHELPS ROSS LESLIE
IPC: F02B1/10
Filed: 1978-01-21
Abstract: The two stroke engine has a fuel injection system (11) whose piezo electric regulator valve (12) is subject to electrical impulses.

Title: Hydraulic steering for articulated vehicle - has preliminary control valve on steering column to set main valve
Inventor: LANG ARMIN
IPC: B62D12/00
Filed: 1979-01-31
Abstract: A hydraulic steering system for an articulated vehicle has a first control valve between the servo steering valve and the pump, to isolate the servo valve for ahead travel and maintain max. pressure in the servo rams. This ensures that the vehicle is held rigid for good control. When the steering turns the first valve provides an increasing pressure for the servo valve. The system enables a heavy articulated vehicle to be steered without having large and complex valves on the steering column. It also isolates the steering when not required and saves fluid, to allow other hydraulic attachments to operate efficiently.

Title: Deburring tool for gear teeth - uses master gear which also checks accuracy of tooth form during deburring operation
Inventor: BEHNKE HORST
IPC: B23F23/12
Filed: 1979-02-08
Abstract: The edges of the teeth of a gear wheel ar de-burred by a tool consisting of a master gear with a toothed disc attached to each face.
