Title: Spatially limited radio communication control - confines transmission and reception within specific region through frequency control
Inventor: FISCHER KARL DIPL ING
IPC: H04B7/155
Filed: 1989-05-23
Abstract: A process for constructing a spatially limited radio link with several mobile subscribers each equipped with a transmitter (3) and receiver (4). Through frequency control a call signal is sent out from the transmitter (3) of a calling subscriber (9). This is picked up and analysed by the receiver (4) of the called subscriber (B) if it falls within the required range. Thus, regulation through the control region confines transmission and reception of calling and called subscribers. USE/ADVANTAGE - For communication between ships, aeroplanes, land vehicles to prevent collisions. Because of limited range there is only small chance of overlap of broadcasts.

Title: Switch cabinet
IPC: H02B1/30
Filed: 1989-06-02
Abstract: A switch cabinet is described having within a housing (which can be closed, for example, by means of at least one door) frames, which are mounted such that they can move about joints or hinges and form mounting supports for electrical and/or electronic switching elements. At a low additional cost, it is in this case intended to make it possible for the frames to be mounted within the housing such that they are variable within wide limits and thus to provide a good matching capability of such a switching cabinet to different requirements. For this purpose, crossmembers 16, which extend parallel to the front opening or opening plane of the switch cabinet, are allocated to the struts 22 of the frames 20, which struts 22 are directed transversely with respect to the joint axis or hinge axis 25 or 26 respectively. These crossmembers 16 and the associated struts 22 of the frames are provided with at least one grid arrangement 15 or 28 respectively, which runs in their longitudinal direction, of engagement openings 17 or 27 or 18 respectively, for example holes 17a to 17d or 27a to 27d respectively, slots 18 or the like. In this case, any desired engagement opening 17 and 27 within the grid arrangement 15 and 28 can be used as a mounting engagement 34, 35 for the joint parts or hinge parts 30 and/or as a holder for the joint axis or hinge axis 29 on the frame 20 and on the crossmembers 16. <IMAGE>

Title: Burner for liq. or gaseous fuel - incorporates system to recirculate products of combustion
Inventor: WITTEK ENGELBERT
IPC: F23C9/00
Filed: 1989-07-14
Abstract: The burner operates using a liq or gaseous fuel is provided with means to return the products of combustion to the burner tube (12). The burner tube (12) has a centrally mounted nozzle (18) for the supply of fuel. The inner surface of the burner tube wall supports a ring of nozzles (30) through which a part of the combustion air flows. These nozzles (30) create a zone of low pressure in the annular chamber (36) formed downstream of the nozzles. The outer wall of the burner tube (12) has a ring of holes (26) in the plane of the nozzles (30). The low pressure in the chamber (36) causes the products of combustion, which circulate around the burner tube (12), to flow through the holes (26) and into the burner tube. USE/ADVANTAGE - Increased efficiency of combustion.

Title: Rolled bar braking plant - with revolving slotted drums, movable shock absorber and discharge carrier
Inventor: IHME FRANK DIPL ING
IPC: B21B43/00
Filed: 1990-03-27
Abstract: A braking installation for fine and medium section rolled bars which have been cut to length retards the bars to zero. The bars enter several revolving slotted drums with shock absorbers in their ends, mounted on wheeled carriages. The braking installation has at least three revolving slotted drums (1). At the rear of each drum, a shock absorber enters the drum at the end of a pneumatic cylinder. Each drum has a semicyclindrical cover (9) with a pneumatic lifting cylinder (7) and is driven by a toothed belt and pulley (3). The stand (8) also carries a rolled bar sensor. Thd drum rotation is coordinated by a computer so that the slot is closed by the cover (9) when a bar enters it. The bar drops ultimately at standstill through the slot to the discharge carrier (13). ADVANTAGE - This reduces the cycle times for bringing short rolled bars to a standstill and for transferring them to the following processes.

Title: TV transmission system for different image format signals - has two portions of extra information in transmitter time ordered for decoding in receiver
Inventor: PLANTHOLT MARTIN DR
IPC: H04N11/00
Filed: 1990-12-10
Abstract: The transmission system is for 4:3 image format, e.g. PAL interlace, and a second image format of 16:9. During transmission the image content in the second format is contained within the first format while on playback invisible additional information signals are transmitted and decoded by a receiver for the second format. Thus, together with the information signal of the image content, a format-filling image is displayed on the receiver. All source signals can be decoded by a receiver for the first image format without extra signal evaluation. In a transmitter the available parts of the extra information are so time arranged that in the receiver for the second image format are simultaneously available for processing on decoding the signal from the substantial image content. ADVANTAGE - Reception detection of standard and letterbox TV signals with extra information signals with relatively small image memory capacity.
