Title: Process and device for comminuting waste tyres
Inventor: PUETZLER FRIEDRICH
IPC: B29B17/02
Filed: 1982-05-07
Abstract: Waste tyres are clamped so as to be rotatable about their axis, and, corresponding to their construction from parts, reinforced to various degrees, comminuted in three operations, with, at first, only the tread of the waste tyre being rotated by steps into the cutting zone. Tread pieces are sequentially cut off. Subsequently, after radial pivoting-in of the clamped remaining tyre parts, that is to say the bead rings with adjoining side surfaces, an analogous comminution of the side surfaces into individual pieces takes place. Tread and side surface pieces fall into different containers. The bead rings are left unsevered. It is intended to dismantle the waste tyres into small pieces and simultaneously sort them directly at the tyre dealer and to provide suitable comminution and sorting machines which can be economically operated on the spot in order to be able to process the waste tyre material to a form suitable for transport within the scope of material reclamation.

Patent DE-3227390-A1 (DE)
Title: Triggering equipment
Inventor: BERGMANN LUTZ DIPL ING
IPC: H02M7/155
Filed: 1982-07-22
Abstract: In this triggering equipment for a converter (11) which is connected to an AC voltage network, for example a controllable rectifier, a synchronising voltage (U6) is formed by detection of the network AC voltage (U) for zero crossovers by means of a phase-locked loop (PLL) with a monostable multivibrator (6) connected downstream. In this case, the network AC voltage (U) may contain harmonics. The synchronising voltage (U6) is compared with a variable control compensating voltage (S) and the triggering pulses (Z) for the valves of the converter (11) are formed from said voltage. The phase-locked loop (PLL) consists in detail of the series circuit of a controllable polarity reverser (1), a phase regulator (2), a low-path filter (3), a voltage/frequency converter (4) and a first bistable multivibrator (5). The voltage/frequency converter (4) emits a square-wave voltage (U4) on its output side at four times the network frequency. The polarity reverser (1) is controlled via a second bistable multivibrator (7), which is connected to the first bistable multivibrator (5), by means of a square-wave voltage (U-) which is phase-shifted through 90 DEG  with respect to the network AC voltage (U). <IMAGE>
Patent DE-3229074-A1 (DE)
Title: Antenna system for a multi-channel receiver consisting of spatially distributed individual antennas having only one feed
Inventor: ANDERS RUEDIGER DR ING
IPC: H04B10/114
Filed: 1982-08-04
Abstract: In order to prevent interfering radiation coupling effects resulting from multiple feeds, especially in the case of direction-finding antenna systems, the individual antennas are constructed as parasitic antennas without feeds but having antenna terminating impedances which can be controlled opto-electrically. The received signals of the individual antennas are in this case transmitted to an auxiliary receiving antenna using the parasitic radiations excited by the radiation. For identification, the respective parasitic radiations are modulated at different frequencies by means of controlling the antenna terminating impedances. The antenna terminating impedances are controlled in an opto-electrical manner, without leads, by means of light transmitters whose brightness is modulated in a phase-lock manner and which are operated via the feed of the auxiliary receiving antenna. The received signals of the individual antennas are thus available at the signal output of the auxiliary receiving antenna in the form of a narrowband frequency-multiplexed signal which is then passed via a single feed to a multi-channel receiver for evaluation.

Patent DE-3302570-A1 (DE)
Title: Machine for the production of textile floor coverings
Inventor: MILKOV MICHAIL JORDANOV DIPL I
IPC: D04H11/04
Filed: 1983-01-26
Abstract: The critical factor in increasing the productivity of machines for the production of textile floor coverings is a constant and uniform speed of the stitch-fixing member. The machine according to the invention achieves this object by the use of an endless screw which is serrated with the stitch-fixing channels and which guarantees a constant and uniform drive of the stitch-fixing member. The shooting-in blade is fastened rigidly to a working beam and is connected slideably displaceably to a guide frame in parallel with the stitch-fixing channels. The guide frame is connected in an articulated manner to a secondary sliding block which is seated in a secondary slotted channel. The primary sliding block located in a primary slotted channel is connected to an adaptation offset of the main shaft. The main shaft is connected coaxially to the output shaft of a reduction gear by means of a coupling. The transmission ratio between the output shaft and transmission shaft of the reduction gear is an integer of not less than 1. The speed of the stitch-fixing member can be regulated by varying the angle between the axis of the endless screw and the walls of the stitch-fixing channels. The stitch-fixing member can also be driven independently by releasing the coupling. <IMAGE>

Title: Ladies' knee-length tights
Inventor: GRENZEBACH BRUNHILDE
IPC: A41B11/14
Filed: 1983-02-12
Abstract: The invention relates to ladies' tights. Since many women wear knee-length stockings during the winter and in the interseasonal period it is very reasonable to wear 30-denier, three-quarter-length tights. The advantages are that they are not bulky, but they provide pleasant warmth which is very important for a woman. Moreover, calves and feet remain free for the knee-length stockings. For the summer period I strongly recommend 20-denier tights which reach to the upper legs and provide great relief for women with a fuller figure; these tights completely prevent the very painful chafing on hot summer days.
Patent DE-3307981-A1 (DE)
Title: Three-point-supported slab
Inventor: RADTKE MANFRED
IPC: E04D11/00
Filed: 1983-03-07
Abstract: The invention relates to a "three-point"-supported covering slab for general use in terrace coverings, flat-roof structures, pedestrian paths, floor superstructures, platforms or similar applications. Its use is appropriate wherever uneven, loadable foundations (bare-concrete floors) or concrete or steel girders having a false bearing are to be covered quickly and reliably without adjustment. For economical and practical reasons, covering slabs having a square or rectangular format are used for the abovementioned work. If such slabs are laid on uneven substructures, adjustment is necessary by placing supports under the corners or sides of the covering slab. According to the invention, the adjustment of the covering slab is no longer necessary, since the principle of the three-side or three-point support is adopted. As shown in the drawing, a square cover slab 3 (compression zone) divided into two identical triangles 3 by a diagonal cut 2 is placed over a baseplate 4 (tension zone) which is relatively thin compared with the total thickness of the slab. The air gap 2 produced by the diagonal cut 2 acts as a joint between the two triangles 3 of the cover slab 3. The baseplate 4 and the cover slab 3 (two triangles) are permanently and firmly interconnected. <IMAGE>
