Title: Container loading device for tipper vehicles - fitted with container reception device including push and pull arms driven by a cylinder unit
Inventor: STAUDENMAIER WALTER
IPC: B60P1/64
Filed: 1974-11-21
Abstract: Loading and unloading device for containers on slide off tipper vehicles which have a tipper frame receiving the container swivelling across for horizontal axis at the rear end of the vehicle.

Title: Control circuit for magnetic induction tracked vehicle - with separate magnets linked to common control by second signal level
Inventor: KLAMKA NORBERT
IPC: B60L13/06
Filed: 1974-12-21
Abstract: The magnetic induction tracked vehicle is fitted with an array of supporting electro-magnets each supplied with its own control circuit and self levelling servo control. The separate systems are combined by a central control, using a second level of signal in such a way that if one or more of the systems fails then the overall control of the vehicle is not affected. This allows the vehicle to negotiate bends etc. more easily with some of the magnetic systems acting autonomously if their controls are set greatly different from the rest.
Patent DE-2505893-A1 (DE)
Title: Pneumatic or electromagnetic hearing protection muffs - are inflated automatically against ear as noise starts
Inventor: BORK NORBERT
IPC: A61F11/14
Filed: 1975-02-13
Abstract: The hearing protection muffs (1, 2) against shooting noise which are attached to a harness (5a) over the head, automatically fit onto the outer ear as soon as a noise generating activity commences. Preferably the muffs are moved automatically against the ear by a pneumatic or electromagnetic force, whereby air stored in a shoulder pad (4) or inside the work gloves is pressed out over an air line (5) into inflatable air pads (3), thus protecting the ears from sound. Alternatively when two switch surfaces are pressed together the current from a battery flows into the electromagnetic surfaces of the hearing protection and both hearing muffs swing against the ears.
Patent DE-2509133-A1 (DE)
Title: IC engine scavenge/supercharge system - introduces high pressure and/or scavenging air at start of compression stroke
Inventor: FRANKE WALTER
IPC: F02B1/04
Filed: 1975-03-03
Abstract: Each cylinder has a scavenging and/or supercharge inlet in the cylinder wall which is uncovered only at piston bottom dead centre, the piston skirt being long enough to completely cover the inlet at all other positions. Each inlet leads to a disc rotated at cam shaft speed and which is able to transfer air from an independently or engine driven compressor to the combustion chamber. The disc is adjustable so that at low performance and slow engine speed, double the air volume is fed before the exhaust stroke and the remainder to the inlet stroke. The disc adjustment is mechanically coupled to the accelerator pedal linkage.

Title: Railway double acting cylinder control - uses reversible motor to drive pump which operates in only one direction
Inventor: RECKLING WOLFGANG DIPL ING
IPC: B61L7/06
Filed: 1975-05-30
Abstract: The control is for double-acting cylinders, esp. for the drive of points and barriers on railways. A motor- driven pump, which conveys in one direction only, supplies a pressure medium via a path valve to one of two chambers of a cylinder, while the second chamber is relieved via the path valve. The pump (KP) is driven by a reversible motor (A), which switches the path valves (WV) between two positions via a transmission (G) in front of the pump, and dependant upon the direction of the motor. The transmission consists of a helical-toothed spur wheel or helical gear transmission between motor and pump. Its take-off (S2) is displaceable in an axial direction, to control the path valves.
Patent DE-2527876-A1 (DE)
Title: Slot wedging construction for electrical machines - has flat spring material and shaped wedge and spring support faces
Inventor: LOTTANTI GIUSEPPE DR
IPC: H02K3/48
Filed: 1975-06-23
Abstract: The construction employs a slot wedge (1), a spring support strip (3) on top of the winding (4), and a spring (2). The facing sides of wedge and support strip have matching profiles, for example the wedge may be concave and the support strip convex. The spring material is flat, and is typically a strip laminate. When trapped between the wedge and support, the spring is deformation. By eliminating the use of formed spring material, which is then flattened to provide the force, the danger of relaxation back to a flat state is avoided, and the flat material is also less susceptible to fatigue.

Title: Time base synchronisation of multiple access data transmission system - uses synchronous generators to minimise effect of time delays at access points
Inventor: PROEGLER MAX DIPL ING
IPC: H04M9/02
Filed: 1975-07-04
Abstract: A time multiplexed data transmission system operates to a synchronised time base using central synchronised word generators to coordinate the operation of multiple access points. The system provides compensation for the delays at access points. In a complex system with a large number of access points, a synchronising generator operates to provide synchronisation between the send line over a junction with the output send line. The junction has two synchronising units, with one coupled to the input send line. Two associated memories are coupled over a demultiplexer, intermediate memories and multiplexer. A phase comparator compares the time base of the synchronisation units. The synchronising word generator generates an output to an internal clock controlled by a synchronising unit and memory coupled to the receive line.

Title: Beam barrier suitable for component construction - has transmitter emitting electromagnetic radiation and receiver for radiation passing through surveillance space
Inventor: WALTER ARTHUR DIPL ING DR
IPC: G01V8/20
Filed: 1975-09-04
Abstract: Beam barrier has transmitter emitting electro-magnetic radiation and receiver for this radiation after passing through the surveillance space.
