IPC: E21C27/32
Filed: 1976-03-03
Abstract: Coal plough guided on a loading ramp has a swivel segment with floor blade for each direction of movement and a swivel flap with fitted face blades. The segment is convex to the floor in an arcuate guide and swings round an axis at an angle to the axis of the flap which itself is at an angle in the vertical plane. The floor cutter segment (19) and face blade flap (15) are so coupled by a power linkage (22-30) that when the flap is extended into the active setting, the segment is automatically retracted and vice versa. The linkage has an angle lever (22) pivoted on the plough to engage the floor cutter segment (19) and connected in its turn through an adjuster (26) to the slap carrying the face blades (15). One arm (29) of this lever should slot into (30) the convex outside of the segment (19), and the second arm (24) should be engaged by the specified adjuster (26). This is pref. a pushrod travelling along a guide (27) within the plough body.

Title: High security transmission of two state information - uses receiver to supply transmitter with encoded auxiliary signal over line to define transmitted signal pattern
Inventor: GO GIOK BIE DIPL ING
IPC: G08B29/10
Filed: 1976-04-10
Abstract: The method transmits two state information down a transmission line with very high reliability, typically for use on railways and other systems where very high reliability is required. The transmitting and receiving equipments operate in a handshaking manner to ensure failsafe operation. A signal generator (1) which responds to some condition to be reported, is linked to a remote receiver via a transmission line (6). The receiver supplies the transmitter with a phase, frequency or pattern encoded auxiliary signal over an auxiliary transmission line (11), and this is used at the transmitter (1) to define the precise pattern of the transmitted signal, typically via a frequency divider (10) and electro optical link (3').

Title: Overload protection for switching transistor amplifier - incorporates additional transistor to act as overcurrent trip
Inventor: NAJIB DIRAR ING GRAD
IPC: H03F1/52
Filed: 1976-07-02
Abstract: The switching amplifier comprises an output transistor (15) controlled by a driver transistor (18). A stabilised power supply (14) is provided for the circuit. The additional transistor (19), acting as an overcurrent protector has its base connected to the main transistor output (17) through a protection diode (22). The collector-emitter path of this transistor (19) is connected between the main transistor base and the driver collector. In normal conducting state all transistors are on. If the load current rises above normal the saturation voltage (Usat) on the power transistor (15) rises. This is equivalent to a drop in potential between the output (17) and the protection and driver common point (26). The main transistor base current is thus diminished causing a further rise in voltage leading to a snap turn off. Capacitors (24, 23) restart the conductibility, and the circuit will remain on if the overload has been eliminated.

Title: Extra safety device for socket for safety and protection - has locking bar with stoppers fitted to sections guided in slot to expose holes
Inventor: BOEKELS BERNHARD
IPC: H01R13/453
Filed: 1976-08-14
Abstract: An additional safety device is fitted to a socket, which will prevent foreign objects from being struck through the socket holes. It will also prevent water and dust from penetrating. The safety device is fitted in such a way that it can be manufactured as an integral part of the socket. There is a locking bar (6) which consists of three offset interconnected locking components each fitted with stoppers (9, 10, 11). The locking bar is guided in a slot (16) when it is pushed back by a plug via a locking prong (5), which will then expose the socket holes. The locking prong is fitted either on the front or reverse side, so that the locking bar will expose the socket holes (2, 3, 4) from the top or from the bottom.

Title: Self-releasing seat belt system - has delayed-action releasing mechanism becoming active after peak value of preset deceleration force
Inventor: FOERSTER HEINRICH
IPC: B60R22/32
Filed: 1976-10-05
Abstract: Both ends of the webbing (1) are connected by a locking clip. One end is permanently attached to a plate (4) which is fitted in the lock housing with the possibility of a slight longitudinal movement guided in lugs (15). The movement has to overcome the force of spring (2). When, due to sudden deceleration, the travel of the plate (4) is long enough, the plate edge is shifted far enough to allow an arm (5) seated on the axle (7) and drawn downward by spring (6) to come to rest against the edge of plate (4). When the deceleration peak has passed, the spring (2) exerts pressure on arm (5), rotation of arm (8) around fulcrum (9) causing tensioning of leaf spring (10) and a subsequent opening of the clip while plate (11) rotates around fulcrum (12) and plate (14) is released from the grip of the nose assembly (13).

Title: Studio control for programmable RAM storing video signals - has start pulses for read and write derived from separate synchronisers
Inventor: MALY HANS-PETER DIPL ING
IPC: H04N5/073
Filed: 1976-10-06
Abstract: The control, for a programmable random access memory storing digitalised video signals in a TV studio, uses vertical-frequency start pulses (6) to define the beginning of signal storage. This pulse is derived from the separate synchronisation component (10) of the input video signal (1) for writing into the memory (4) and from the TV studio sync. signal for reading out of the memory. The positions of these pulses depend on the positions of the vertical pulses in the corresp. synchronisation signal. The vertical-frequency start pulses are compared in a coincidence circuit start pulses are compared in a in the synchronisation component. The phase of the studio synchronisation signal may be continuously adjusted.

Title: Electronic revolution rate measuring circuit - is for brake testing and uses delay monostable for direct test bed motor control
Inventor: KNESTEL ANTON
IPC: G01P1/10
Filed: 1976-10-26
Abstract: The electronic revolution rate meter is designed to detect wheelslip occurring on vehicle brake test stations, in partic. to indicate jamming or locking of wheels. The binary output of the meter changes state when the measured revolution rate exceeds or falls below an adjustable rate. A pick-off wheel converts the wheel rotation speed into a proportional revolution rate and has a magnet fixed to it which operates a reed switch producing an electronic revolution rate signal which is evaluated by a monostable circuit. Large switching delays can be achieved by adjusting the monostable flip-flop thus enabling the motor driving the test bed to be controlled by the meter without additional time relays.

Title: Pressure roller assembly - has a single roller with two counter-rollers to give two pressure gaps of different values
Inventor: LEHMANN ROLF
IPC: D21G1/00
Filed: 1976-12-17
Abstract: The pressure roller assembly for processing paper of fabric webs incorporates two pressure gaps for the material to pass through, each with independent and different pressures. The two pressure gaps are formed by an assembly of three rollers, arranged in two planes with their axes parallel to each other. The roller lying between the other two rollers forms the two pressure gaps, and acts as a pressure equalising roller. The roller is mounted on a fixed carrier with a rotating roller mantle held by hydrostatic supports parallel to the pressure gaps. The pressure in the gaps is determined by the action of the hydrostatic supports acting on the roller mantle of the pressure roller. The mantle of the pressure roller acts radially to the carrier, while the two counter-rollers are guided radially and axially. As there is only one pressure equalising roller, the assembly is simple and cheaper than conventional units.

Title: Sectioned large pressure vessel - has axial and circumferential divisions welded up on site after road transport
Inventor: CZERNIK ALFRED ING GRAD
IPC: F16J12/00
Filed: 1977-01-29
Abstract: The pressure vessel too large for road transportable sections connected on site. The vessel is tubular and is divided both along axial and along circumferential lines. In this way each section is in effect a curved plate. The axial dividing lines may be 180 deg. or 120 deg. or even only 90 deg. apart so that the sections can be readily nested together for transport. At the site the sections are connected e.g. by welding. Circumferential seams may be welded automatically and only the axial seams need be welded by hand.
