Title: Arrangement for presetting starting pulses for converters
Inventor: GORETZKY DIETER DIPL ING
IPC: H02M1/084
Filed: 1984-06-01
Abstract: An arrangement for presetting starting pulses for converter bridge circuits which are operated and switched differently, having a microprocessor which produces the starting pulses for the converter via a digital memory, having an oscillator for emitting clock pulses to a downstream-connected frequency divider, and having an address counter. Universal converter operation is made possible with a microprocessor being used for a small amount of time in that the memory contains a plurality of pulse patterns for the operating modes of the converter which are provided, which pulse patterns can be called up by the microprocessor via a list of pattern numbers, and are processed periodically and completely via the address counter. The microprocessor accesses the production of the control pulses only in the event of a change in the frequency or the phase angle of the control pulses with respect to a predetermined control frequency, via a programmable divider or by means of an offset change in the address counter. <IMAGE>

Title: Switching contact for a vacuum interrupter
Inventor: HOENE ERNST-LUDWIG DR RER NAT
IPC: H01H33/66
Filed: 1984-12-18
Abstract: In order to produce an axial magnetic field, contacts are used in vacuum interrupters, which contacts have conductor loops behind the contact pieces, the magnetic fields of which conductor loops run over the contact surfaces of the contact pieces in the direction of the rotation axis of the switching contacts. In order to be able to dimension such conductor loops with a small cross-section and in order to be able to produce them simply for this purpose, it is proposed that each conductor loop (2, 3) represent a separate component, that two connecting surfaces of this conductor loop be formed by means of a flat slot (6, 7), and that this flat slot originate from the rotation axis of the connecting bolt and be guided parallel to or inclined with respect to the rotation axis. The invention is suitable for vacuum interrupters for high short-circuit switching-off currents. <IMAGE>

IPC: B65G47/82
Filed: 1984-12-20
Abstract: Attachments (11) are placed on the conveyor belt (10) which each hold a tube (12) in a trough horizontally in the conveying direction. The tube is to be ejected to the left or right on a grid (13) in the target region of the conveyor belt. To this end, a plurality of levers are mounted about a common horizontal axis (16) below the conveyor belt in the region of the grids. By rotating a camshaft (17), the levers are pivoted slightly upwards, so that the conveyor belt is inclined slightly towards one side and the tube is ejected there onto the grid. The conveyor belt is raised very rapidly, in a fraction of a second, so that the direction of ejection is still essentially transverse to the conveying direction, even when the belt runs very quickly, for example at a rate of 5 metres per second. Crank systems may also be used as a lifting device. <IMAGE>

Title: Device for cleaning containers, especially bottles
Inventor: GRAESSLE WALTER
IPC: B08B9/34
Filed: 1986-02-21
Abstract: In the case of a device for cleaning containers, especially bottles, by blowing out or spraying out, each chain link is provided with a gripping device for the bottle neck on the one hand and a fixedly mounted nozzle on the other, which nozzle is actuated by the gripping device. This ensures perfect synchronism between the bottle to be sprayed out on the one hand and the nozzle on the other, the nozzle is not obliged to be moved in and out of the bottle neck and additional measures can be taken to ensure that the gripping device only pivots onto a valve controlling the nozzle and operates the said valve when a bottle has been taken hold of at the same time. This makes it unnecessary to use covers like those used in known machines to protect against spraying actions when bottles have not been inserted.

Title: Digital adapter for micrometer spindles in particular in machine tools and automatic machining units
Inventor: LUEDTKE KURT
IPC: B23Q17/22
Filed: 1987-01-10
Abstract: The invention relates to a digital adapter for micrometer spindles which are available to set up and adjust tool rests, in particular in cam-controlled machine tools and automatic machining units, for the fine adjustment of the tools. These micrometer spindles have hitherto been operated manually in a laborious and time-consuming manner. The object of the invention is to replace this outdated manual operation by a digital adapter which mainly consists of a housing with adaptive gearing and stepping motor. The digital adapter is simply put on and secured without significant interference with the machine. The easy actuation is effected via a control panel by "+" and "-" keying with simultaneous digital preselection and digital display. This ensures that, apart from the easy and accurate operation, the dimensional corrections to the individual tools can be made without interruption during the operating cycle with reference to the test workpieces which arise.
