Title: Roadway support machine for driving curves and branches
Inventor: HESSLING JOSEF DIPL ING
IPC: E21D11/40
Filed: 1987-09-17
Abstract: A roadway support machine or roadway support apparatus is for the first time also able to completely drive and support roadway curves and branches in the heading. To this end, the working platform and the support-setting device are designed in such a way that they can be pivoted or rotated individually in the horizontal, the support-setting device conveniently having an interchangeable support traverse with a support pocket. Various embodiments are conceivable for the rotating or swivelling capability of the working platform and the support-setting device, where the simplest for the swivelling capability of the support-setting device is that in which an interchangeable support traverse is arranged at the top on the parallel-linkage boom. For the driving of the roadway curves and branches, the support traverse has a perpendicular swivel joint at the end of the cross beam. A supporting arm with the support pocket can be swivelled around the swivel joint. The swivelling capability of the working platform is advantageously effected by a slewing ring with upright slewing cylinder being provided. The slewing ring has a sectional gear rim which in turn meshes with a rack attached to a thrust cylinder. By backward and forward pushing of the thrust cylinder, the sectional gear rim is influenced and turned via the rack in such a way that the working platform moves into the position intended in each case. <IMAGE>

Title: Flat umbrella for young people
Inventor: RAFF WILLI
IPC: A45B25/02
Filed: 1988-01-18
Abstract: In order to encourage today's youth to use an umbrella more frequently, the greatest importance was placed on the design. In the closed state, the flat umbrella for young people differs from that commercially available due to its external appearance. The appearance was changed in that two foldable semi-shells are mounted without a transition on the dual-walled handle. These semi-shells enclose 2/3 of the umbrella covering in the closed state. A double-sprung ratchet can only be unlocked after pulling the dual-walled handle back axially. Beforehand, the two semi-shells must be opened out. The umbrella stick is reshaped beyond the ratchet in the direction of the umbrella covering from a round to a double-T profile in order to be more compact. The main and auxiliary struts are held in each case by two easy-to-assemble clips. The flat umbrella for young people as a problem solver: in an upright position, the closed, wet umbrella collects the rain water still adhering to the umbrella covering in the handle. Owing to the reflecting semi-shells which reflect in headlights, the umbrella user is far safer at night.

Title: Cell former in an asynchronous time division multiplex system
Inventor: SZIGETI TIBOR DIPL ING
IPC: H04L12/70
Filed: 1988-03-26
Abstract: Arrangement for the formation of cells for a broadband communications network. Packet forming methods using computer routines are ineffective here due to the high data transmission speeds. The cell former is intended to be able to process input clock frequencies from several kHz into the MHz range and to emit output clock frequencies in the 200 MHz range. The subscriber data stream (D1) is read into a first in/first out buffer memory (FIFO). If the bit set corresponding to an information part of a cell is read in, the contents of a shift register (SR1) are incremented by one. Only when at least one >>1<< has been written into this shift register (SR1) can a prompt signal (A) initiate the read-out, first of the permanently stored cell header (R1 to Rm-1), and then of the information part from the buffer memory (FIFO). Following each read-out operation, the contents of the shift register (SR1) are decremented by one and updated in line with the contents of the buffer memory (FIFO). The cell formers are used in broadband communications networks whose subscriber-end network termination equipment enables the simultaneous operation of a plurality of terminal devices and transmission between the network termination equipment and the terminal devices is performed via an active transmission bus. <IMAGE>

To achieve this, preliminary memories are provided in each case at the storage point into which the new data are first read, and the contents of the preliminary memories are compared with the data which are already stored. Only data which have not yet been stored are read in. Existing data are deleted from the preliminary memories.   The method is used in digital terminals with storage devices which are provided for mobile ancillary dialling units. <IMAGE>
Patent DE-3816492-A1 (DE)
Inventor: MICHEL-KIM HERWIG
IPC: F27B19/00
Filed: 1988-05-09
Abstract: A process and an installation for the thermal treatment of solids in an oxidising or reducing environment is proposed, in which two regenerators are interconnected via a furnace. The solids are introduced into the furncae in the centre and distributed, after burning, in approximately equal parts to the regenerators. Combustion air, which is heated in the respective regenerator by means of the solids and, after leaving the respective regenerator, is further heated for the implementation of the thermal treatment, is introduced, in each case reciprocally, into the regenerators. After completion of the thermal treatment, for example after burning of the solids with the heated gases, the hot gases are supplied to the other regenerator respectively, and transmit their heat to the solids. After a clock time, the direction of flow of the combustion air introduced and thus of the hot gases also is reversed. <IMAGE>

Title: SF6 single-pressure circuit breaker (puffer circuit breaker)
Inventor: KARRENBAUER HERBERT DR ING
IPC: H01H33/915
Filed: 1988-12-23
Abstract: The invention relates to the improvement of a circuit breaker according to the main patent P 3810091. In the case of this circuit breaker, light-current arcs are blown via a compression device, while, in the event of heavy-current arcs, a closure device (8) closes the compression device and self-blowing is carried out via a gas storage space (9) and a compression chamber (3). In the case of this circuit breaker, there is hot gas of low density in front of the switching path after a heavy-current arc has been interrupted. This is disadvantageous for renewed blowing of an arc. Cold extinguising gas is also provided in such a switching situation by a valve opening during the connection operation and in consequence creating a connection between the pressure chamber (3) and the compression space (11) through which fresh extinguishing gas is sucked out of the switching chamber into the pressure chamber (3) and is available for arc blowing once again. <IMAGE>
