Patent DE-2360284-A1 (DE)
Title: Lifting table safety device - has connection between contacts broken on safety strip striking obstruction
Inventor: ALTMANN HANS-JOACHIM
IPC: B66F17/00
Filed: 1973-12-04
Abstract: A safety grip runs round under the edge of the table and moves towards it on hitting an obstruction, actuating a switch stopping table movement. There are a series of contacts between table and strip, insulated from both, connected to opposite poles of a fail-safe transistor relay of the micro-ampere type. When the strip moves towards the table, these contact part, and stop the table drive. The equipment operates irrespective of whether or not the contacts are dirty. Typically a non conducting sleeve projects downwards from the lower part of a U-shaped framework its length being approx. half that of the spacing between this lower frame member and the safety strip. A contact ring is at the lower end of this sleeve. A further sleeve extends up from the safety strip with a contact ring at its upper end.

Title: Swashplate type compressed air motor - has circumferential grooves in shaft for admission and exhaust of air
Inventor: KAUFMAN MICHAIL SEMENOWITSCH
IPC: F01B3/00
Filed: 1973-12-07
Abstract: The motor has a casing with a drive shaft. Several axial cylinders are arranged round the shaft and each contains a piston. The shaft carries a cam-shaped swashplate which runs through slots in the casing and slots in the pistons. Each piston slot contains a roller by which the piston presses on the swashplate. The casing has openings for admission and exhaust of air and these communicate with circumferential grooves in the shaft. The grooves are connected to longitudinal passages in the shaft which bring the air to the cylinder ports and take the exhaust air out from the ports. This method of introducing and exhausting air enables a motor of large power to be contained in a small volume.

Title: Removal of dust from ventilation air - esp for mining with water jets and rotating vanes
Inventor: AUGST ANTON
IPC: E21F5/20
Filed: 1973-12-17
Abstract: Dust remover from treating air (or gas) streams laden with fine dust consists of a hollow cylindrical rotor with conical inlet. Inside this is a hollow cylindrical rotor with a conical leading face in which a series of tangential jets are positioned. The device is attached to a fan via a shaft which is directly coupled to the fan shaft. The shaft runs in a bearing. Water is introduced via the bearing support hollow shaft and distributors, to the sprays. The rotor has a series of inclined vanes at regular intervals around its circumference. Dust is wetted out and trapped on the walls of the shell. Esp. for atmos. conditioning in underground cavities where mining operations are in progress. The device is very much more compact than conventional scrubbing plant and can be made mobile so as to move with the cutting equipment. This ensures that operating personnel are always protected from the dust hazard.

Title: Linear coding method for colour information - reduces irrelevance during colour coding in colour TV transmission system
Inventor: STENGER LUDWIG DIPL ING
IPC: H04N11/04
Filed: 1974-04-29
Abstract: Colour information for a colour tv transmission is color-imetrically arranged in a standard colour triangle, and chrominance signals, or colour difference signals derived from them are converted in a coder which carries out at least two further coordinate transformations, one of which balances out different eye sensitivities in different areas of the colour triangle, while the second makes the colour triangle area to be quantised as small as possible. After decoding at the receiving end, signals are correspondingly converted back to their original form. The first coordinate transformation is carried out in accordance with given standards.

Title: Thermostat controlled valve for heating installations - has separate valve which closes when max temperature is exceeded
Inventor: BRAUKMANN BERNHARD W
IPC: F16K31/68
Filed: 1974-05-09
Abstract: The valve housing has two valve seats which are arranged behind one another in the direction of flow through the valve. The valve seats are formed by the ends of a bush which is fixed securely in the valve housing. Each valve seat acts with a separate valve body. The position of one valve body is controlled by a thermostat and moves against the direction of flow when closing against the force of a spring. The second valve located upstream of the first valve is kept in the open position by a locking mechanism against the force of a valve closing spring. The locking mechanism can be released by a safety thermostat when a certain maximum temperature is exceeded. The valve then closes while moving in the direction of flow through the valve.
