Title: Air vent for engine coolant system - has air venting connection to radiator header to allow proper access of liq. coolant to thermostat
Inventor: MAYR BERTOLD DIPL ING DR
IPC: F01P11/02
Filed: 1976-04-10
Abstract: The liquid coolant system for IC engines, with a vented thermostat chamber is conventional with a thermostat-operated double valve progressively opening the coolant line from the radiator to the engine and closing the radiator bypass as the engine warms up. The chamber around the thermostat element has an extra connection to the coolant return pipe from engine to radiator. Due to its buoyancy, any air collecting in the chamber will escape through this connection and rise to the radiator top header. This ensures proper coolant access to the thermostat element and thus correct and rapid response of the system to coolant temp. changes.
Patent DE-2617374-A1 (DE)
Inventor: SEIFERT WILHELM
IPC: B01J8/00
Filed: 1976-04-21
Abstract: A main piston (6) and a precursor piston (8) are arranged in a cylindrical dosing tube (5) which opens into a dispensing region (9). In the initial position, a chamber (4) is formed between the main piston (6) and the precursor piston (8). By the simultaneous advance of the two pistons (6, 8), the dose is moved into the dispensing region (9). After the solid material has fallen out, the precursor piston (8) is first of all moved back until it rests against the main piston (6). After this, both pistons are first of all moved back simultaneously until the precursor piston (8) has reached its initial position. When the main piston (6) is then moved back into its initial position, the chamber (4) is reformed. Any change in the dose is made by changing the spacing between the main piston (6) and the precursor piston (8). Solids are prevented from sticking in the delivery chamber (4) by rotation of the precursor piston (8). Since the filling region (1) is separated from the dispensing region (9) during the entire operation, different pressures and humidities may prevail in the two regions. <IMAGE>

Title: Automated railway contactless distance and velocity sensor - has transverse magnetic conductors interacting with AC solenoids in vehicles
Inventor: HERMANN WALTER DR RER NAT
IPC: G01C22/02
Filed: 1976-04-24
Abstract: The contactless distance and velocity measuring system is used for railway vehicles. The arrangement has magnetic transducer and associated magnetic distance markings. This arrangement is used especially for tracks with automatic safe internal braking and travel control of the vehicle. The arrangement has response time of a few seconds. This can be used also for control of cranes and machine tool slides. Closely spaced magnetic conductors are provided at regular intervals along the track (3). These conductors are arranged across the track longitudinal axis. Each vehicle has an A.C. powered solenoid. The velocity information is derived by the frequency generated due to the changes in the permeability of the conductors and the inductance changes in the solenoid (6).

Patent DE-2627006-A1 (DE)
Title: Sewing machine fabric stacker - uses a transfer unit which moves vertically to the start position after horizontal transfer to stack table
Inventor: FENZL HORST
IPC: D05B41/00
Filed: 1976-06-16
Abstract: As stitched fabric passes from a sewing machine, it is drawn out and laid flat, with successive stitched fabrics forming a stack. While the fabric is drawn along a horizontal plane above the supporting table the fabric transfer unit also moves horizontally. When the material has been laid, it moves vertically, travels to the start position and then reassures its horizontal orientation. The design allows wide fabrics to be stacked and the transfer unit to be returned to the start position without interfering with the prepn. of the next material length to be handled.
Patent DE-2627163-A1 (DE)
Title: Workpiece holding clamp jaw pair - has lazy tong linkage actuated by screw element
Inventor: OWEN WALTER L
IPC: B25B7/12
Filed: 1976-06-16
Abstract: The pair of work engaging jaws of a clamp device are interconnected by linkages forming part of a manually operable force multiplying mechanism. A movable work engaging element mounted by one of the jaws, is actuated by a grip lever from a retracted position into engagement with a workpiece. An over-centre linkage transmits the actuating force against the resistance of a spring to prevent return of the grip lever from its actuated position. A release lever is actuated to cam the grip lever and retract the work engaging element. A single spring biases the work engaging element to either of its positions and thereby also yieldably holds the grip lever in either its inactive or actuated position.

An axial array of annular sheet metal plates (18, 19) is arranged between the sleeves, and the plates are connected alternately to the respective sleeves in axially slideable manner. The plates are pressed together by tension bolts (25) extending through curved slots in the plates. Torsional sliding between the plates is facilitated by the maintenance between them of layers of high viscosity grease.

Title: Foam packing material with surface layer of e.g. paper - has improved transverse rigidity, is offset printable and cheaper to produce
Inventor: PETERMANN ERICH P
IPC: B31F1/28
Filed: 1976-07-06
Abstract: A packing material with >=1 intermediate layer of foamed resin, has the foam layer comprising a deformed web of polystyrene foam, the peaks of the profile of which are covered on one or both sides with a surfacing layer. The foamed layer may be a polystyrene foamed web machined into an undulating contour in the longitudinal direction, with the crests of the waves bonded to a covering layer on each side. The prodn. process may commence with a prefoamed polystyrene foamed web which is raised to the plasticising temp. to cause secondary foaming, in a heated bath of hot water. Whilst at the plasticising temp. it is deformed and then cooled, to be clad on one or both surfaces on the profile peaks. The laminate has the high degree of transverse rigidity missing from conventional packing materials of this type. It is resistant to humidity, requires the min. of raw materials for its prodn. and it can be offset printed.

Title: Polishing system for electron tubes prodn. - uses polishing acid bath for contact surfaces of screen and bulb cone
Inventor: SAELZLE ERICH DR
IPC: H01J9/26
Filed: 1977-03-31
Abstract: In the production of electron tubes, such as cathode-ray tube, the bulb cone is sealed to the front plate. In order to obtain a hermetic seal, the contact surfaces of both component parts must be highly polished. This is attained by inserting the edge regions into a bath of a polishing acid. The latter is contained in a trough whose shape corresponds to that of the connecting surface. During the process the polishing acid is continuously stirred and preferably held at a low temperature between 0 and -20 deg.C. During the immersion the salt deposit is continuously brushed off from the connecting surface. Specified mixtures of flouric and sulphuric acids are used for the polishing, while sulphuric acid solution may be used for final brushing.
