Title: Electrical rotary pulse generator - has coding disc on shaft to trigger non-contact sensors to generate predetermined pulse sequence
Inventor: DOLDERER ERICH A
IPC: H03M1/30
Filed: 1975-10-21
Abstract: An electrical rotary switching unit generates output pulses dependent upon angular positions defined by a coding disc. An output shaft is rigidly coupled to a drive unit and carries a stationary housing (1, 12) supported on two roller bearings (2, 3). The shaft has pre-loading discs (6, 7) to eliminate play and a disc (19) is attached to the free end. Raised segments (31) attached to the disc define the angular switching positions. A fixed disc (26) with the housing carries an electrical signal generator (28) that is triggered by a rotating segment on the moving disc. A number of sensors may be located to generate pulse trains of particular phase relationships. An alternative form uses a coding cylinder to enable a number of multi-bit coded signals.

Title: Mfr. of charge coupled device - uses two stage polycrystalline silicon layer process allowing formation of MOSFET on same substrate
Inventor: WULF HANS-JUERGEN DIPL ING
IPC: H01L21/033
Filed: 1976-07-29
Abstract: The charge-coupled device is made in such a way that MOSFETs can be built on the same substrate at the same time. The process includes local oxidation followed by photo-processing of the active region. After gate oxidation the first polycrystalline silicon layer is deposited. This silicon layer is photo-processed and oxidised. A second plycrystalline silicon layer is then deposited and photoprocessed in forming the CCD part. Oxide etching is carried out followed by diffusion of intermediate oxide. Aluminium is evaporated on to the surface for photoprocessing prior to covering with a final oxide layer. This is photo-processed to produced pad windows.
Patent DE-2637269-A1 (DE)
Title: Reciprocating compressed air engine - has opposed cylinders with valves admitting air in alternating sequence
IPC: F01B7/00
Filed: 1976-08-19
Abstract: Air enters the engine from a compressed air reservoir through a spring loaded valve. It flows through one of two inlet passages (C) to act on the working surface of a piston (A) which reciprocates horizontally in a cylinder. The piston is pushed forward and drives a crank through a conventional connecting rod linkage. As the piston reaches the end of its stroke an auxiliary valve piston (B) attached to it by an extention of the piston rod covers the inlet passage (C). The air entering from the reservoir is now diverted to the second inlet passage (C') which leads to a second identical cylinder and piston in which the same operating process then takes place.
Patent DE-2642978-A1 (DE)
Title: Tennis racquet with high friction stringing - has friction inserts with V-shape grooves wedged at crossing point of strings
Inventor: SOMMER REINHOLD
IPC: A63B51/11
Filed: 1976-09-24
Abstract: The tennis racket has crossing strings which tend to loose their proper spacing during play. to prevent the strings (3, 4) from sliding relative to each other a grooved insert (5) is located at each point where two strings cross. The inserts, which are made from a material of a high friction coefficient, have also VEE-shaped string grooves to provide wedge location on the strings. The inserts (5) protrude above the strings (4, 3) on each side of the racket. They thus produce a racket surface which gives a high friction when in contact with a tennis ball. It is therefore easily possible to produce tennis strokes which provide plenty of ball spin.

Title: Multi-hearth baking oven with common gas system - has damper controls interlocked to maintain partial circulation at all times
Inventor: HEINRICH PETER ING GRAD
IPC: A21B1/40
Filed: 1977-01-27
Abstract: A baking oven with circulating hot gas has at least two separately regulated hearths; the hot gas ducts connected to the top and bottom of each hearth all lead into a common gas duct. Each hearth has its independent thermostat for regulating the dampers connecting that earth to the main gas circulation system. All these dampers are connected to a common drive system, operated by a single actuator. The thermostats in the separate hearths operate switching elements for the actuator; switches are also operated by the guide system. These switches ensure that, when the system is changed from the position in which all the dampers are open, the dampers of individual hearths are closed, but one set of dampers is always open to allow the gas to continue to circulate. Since the hot gas continues to circulate, a build up of heat which can damage the burner is prevented.

Title: Vehicle shock absorber check valve - has seats in series, separated by expansion chamber to reduce noise
Inventor: NACHTIGALL ALBRECHT ING GRAD
IPC: F16F9/508
Filed: 1977-06-18
Abstract: The check valve for telescopic shock absorbers for motor vehicles has a closure member being a disc (9) spring-urged against a seat member (1). This has two concentric annular seats (10, 11) with an annular expansion chamber (21) between them.

Title: Seat belt retractor blocking mechanism - has torsion rod with optionally variable span connecting spool and blocking assembly
Inventor: BECKMANN HANS-DIETER ING GRAD
IPC: B60R22/28
Filed: 1977-06-18
Abstract: The seat belt retractor blocking mechanism is fitted with an energy dissipating device in form of a torsion rod with a variable length of chucking to suit the body weight and/or seating position of the user. The coils of webbing (3) are taken up by spool (4) seated in housing (1). One side of the housing carries stationary blocking teeth (13) working together with teeth (12) of rotary blocking assembly (7). The engaging process of the two sets of teeth is induced either by the action of an inertia mass causing a catch to engage with on of the external teeth (20) whereby the co-rotation of wheel (11) is stopped and the wheel is forced to perform an axial movement due to the chamfered surface on wheel (8) and (11). Similarly a sudden jerk on the seat belt and subsequent extreme acceleration of the spool rotation produces the same sequence of operation.
