Title: Mounting assembly for electrical equipment - holds electric installation on equipment housing wall in one of two orthogonal positions
Inventor: SCHMALE JOHANNES
IPC: H02G3/10
Filed: 1974-05-06
Abstract: The mounting assembly, for holding an electrical installation to the wall of equipment housings, has the installation (1) fixed to the wall in either of two orgonal planes A, B).

Title: Error checking system for data transmission from tape - checks synchronising bit group using comparator and bit sub-groups location
Inventor: STEFFENS KLAUS
IPC: G11B20/18
Filed: 1975-01-28
Abstract: An error checking circuit monitors the validity of data from magnetic tape resulting to an 80 bit European Broadcast Union Standard. The 80 bit coding sig nals are generated in groups in serial fashion with spacing intervals between each group. The 80 bits are read into a shift register and a synchronising group of bits are transmitted to a comparator which is supplied with a standard reference input. An additional check of the word is made by checking that all spacing intervals are generated correctly by coupling the outputs to a NOR gate. Only if the NOR gate and comparator generate the correct output is a new word allowed to be transmitted from a buffer store to the register.

Title: Control for infeed of tool slide - has slide operating pin engaging with stops on second slide
Inventor: IMGRUND HEINRICH
IPC: B23Q16/00
Filed: 1975-04-22
Abstract: The tool which is to be moved towards and from the workpiece is mounted on a slide (4) which is moved by an actuator (7). Control of the movement of the slide is effected by a stop plate (15) which is mounted on a second slide (16) which can move parallel to the first slide. The second slide is moved to and fro by screw spindle (18). The first slide carries a gear rack which drives a second gear rack via a pinion (11). The second gear rack is vertical and is attached to a lever (27) with a groove on which a stop pin (30) can be secured in a selected position. The stop pin engages at the end of its travel with a stop plate (15) with sloping side. Infeed of the first slide towards the workpiece by the actuator is fast till the pin hits the stop plate. The slope on the stop plate ensures that infeed proceeds more slowly. A second stop plate with a sloping face parallel to that of the first plate ensures that the tool is then first retracted slowly, e.g. while machining an end face, after which it can be removed rapidly.

Title: Location system for fixed radar installations - has rotating aerials and obtains fix within one rotation period using three separately located receivers
Inventor: GISSKE WALTER DIPL ING
IPC: G01S5/04
Filed: 1975-08-13
Abstract: A system for the location of fixed radar installations with rotating transmitter aerials is designed to considerably reduce the measurement time relative to known methods. The system uses several receivers separated by defined minimum distances and enables location within one rotation of the aerial. At least three receivers (A, B, C) are used to measure the rotation time of the transmitting aerials and the time interval between the reception of the amplitude maxima in the individual receivers. From these measurements the angles in the horizontal plane (a1, a2) between the lines from the receivers to the aerial are determined.

Title: Valve for pressure gas packing - has profiled seal thinner in outer ring section than unloaded clamping region
Inventor: ZIMMERHACKEL FRANZ
IPC: B65D83/14
Filed: 1975-12-13
Abstract: The valve for pressure gas packing has a seal which rests with its outer border at least partly on the inner circumferential surface of the valve support or on a part connected to it. The seal is profiled and has a thickness which is less in a ring section positioned beyond the clamping border (7) than it is in the unloaded clamping region (a). The ring section of smaller thickness is bounded at least on one side by a cone surface. Charging channels (25) are located near the circumferential wall (4) of the valve support (2). A bypass chamber (24) is formed between the ring section and the neighbouring housing part.
