Title: Constant supersonic measurement of distance - is for ski-jumping and uses a transmitter and receiver accurate to one cm.
Inventor: WEYER WALTER
IPC: G01S11/14
Filed: 1973-09-27
Abstract: The high-frequency transmitter reacts to shock and emits a signal. The receiver retains the high-frequency signal on arrival from 1. The ski-jumps are accuratel measured and the measured results of the distance will be more accurate, similar to other sports. The performance of ski-jumpers is often very close and a centimetre can be qdecisive. Distances will be measured in centimetres and not in 50 centimetres. Transmitter and receiver can be connected to a display device. The transmitter responds, when the jump commences and the receiver completes the measurement, when the ski-jumper touches the ground.

Title: Self regulating mixer unit for hot and cold water - uses thermal expansion tube for operating valve slider
Inventor: GRZANNA KURT
IPC: G05D23/13
Filed: 1974-01-25
Abstract: A mixer unit for fluids of different temperatures has a cylindrical expansion tube placed inside the mixer body. A piston divides the mixing chamber from a control chamber which contains a constant amount of a fluid. When the expansion tube alters its length, it moves the control piston. This causes the control fluid to displace a smaller central piston inside the main piston to axially move a valve slider, thus changing the inflow ratio of the two fluids. A regulating knob linked to a third piston which extends into the control chamber is used to set the required outflow temperature.

IPC: F16H9/20
Filed: 1974-05-24
Abstract: Drive is transmitted by V-belt between two V-pulleys each having two axially movable halves whereby to vary their effective diameter. The pulleys are mounted on respective driving and driven shafts. The effective diameter of the driving pulley is regulated by centrifugal masses arranged to urge the halves of the pulley towards each other to increase the effective diameter as rotational speed increases.

Title: Pallet system for logs ensuring in-line stacking - top logs are at fixed height and logs lie on tensioned cable (in pallet) that has linear tension-deflection characteristics
Inventor: FLECK WERNER
IPC: B65G57/18
Filed: 1974-06-18
Abstract: Logs of a fixed pre-cut length are loaded into a pallet with all axes parallel and occupying minimum volume. The pallet is constructed from box section struts (71, 72, 73) with angle section cross-struts (74). Steel cables (4) are fixed to one side of the pallet (75) and are wound around a sleeve (51) carried on a shaft. Spring tensioning devices are built into the shaft supports (52). Logs are transferred from a transport track onto guides (11) and down onto the tensioned wires. The cable tension has a linear characteristic so that every time a log is added the cable extends by constant amount. Logs may be added until the pallet is completely full and the cable at full extension. The pallet system ensures that the top logs in the stack are at a fixed height which simplifies unloading.

Title: L.F. power amplifier - has push-pull output stage in bridge cct.
Inventor: FIGOL GEORG DIPL ING
IPC: H03F3/26
Filed: 1974-07-02
Abstract: Only two bridge transistors operate in push-pull as linear amplifiers, while the two other are pulled by the former, but can, if required, be replaced by electronic switches of any type. One application is for a car radio amplifier giving an output power of around 16 Watts at an impedance of 4 Ohms with a power supply of only 12V. The phase splitting is achieved via a difference amplifier. Resistors serve as the opposition coupling of the amplifier. The complete bridge current flows through a low value resistor in order to stabilise the basic current. The resultant voltage drop is used as a regulating voltage for the basic current.

Inventor: SCHWOLOW GUNTER DIPL ING
IPC: D02J1/22
Filed: 1974-08-16
Abstract: A coal mining method employs two scraping type mining tools which are both pulled along the same seam, one scraper being (4) pulled by a chain (6) on the face side of the conveyor (2) with a drive unit and winding drum (8, 80) each end of the section to be cut, and the other scraper (3) pulled by a second chain (5) on the stowing side of the conveyor with a second drive system (7, 70) on the stowing side. The second scraper is connected by a cross member which travels under the conveyor, so that is can be pulled from the stowing side. Both cutters receive support from the sheeting covering the chain on the face side, being shaped accordingly to overhang it. The two scrapers are then worked to operate on different portions of the same seam.
