Patent DE-3022756-A1 (DE)
Title: Vehicle seat belt retractor - has torsion spring on shank of double catch, to release it when return spring force prevails over catch spring
Inventor: FOEHL ARTUR
IPC: B60R22/353
Filed: 1980-06-18
Abstract: The base side plates have bores (8) in which bearing elements (9) seat the ends of the axle (7) on which the spool (10) rotates. On the external surface of one of the side plates a spring housing (19) accommodating a spiral spring (17) is fitted. Both side plates have shaped slots (32) in which the ends of the catch (30) seat. The shank (34) of the catch has a torsion spring (35) fitted so that normally the spring forces the catch legs (33) to engage with tooth flanks (13) of the ratchet wheels (12). When a length of belt is uncoiled, the tension of the spiral spring increases until it exceeds that of the torsion spring. At this point the housing (19) performs a limited rotary motion forcing the catch to swing out from engagement with the tooth flanks.

Patent DE-3044300-A1 (DE)
Title: Piston pressure sensor for liq. or pasty media - avoids frictional error by filling piston cylinder gap with powder or paste
Inventor: KESSLER KARL H ING GRAD
IPC: G01L9/00
Filed: 1980-11-25
Abstract: The pressure pick-up operates by conversion into electrical values. It can be used in the chemical industry for fluid or paste-like substances which can have high temperatures and abrasive qualities. The usual diaphragm is obviated since this is the common cause of errors from friction in the wall to piston gap. In fact, there is no relative movement between the plunger and cylinder under pressure influence. Relative movement can be established between a cylinder cover and a housing bore, the pressure medium being in contact with a cylinder in a receptor housing. The plunger and electrical transducer can be in two parts. The counter bearing for the plunger can have a central recess for the plunger or pressure transducer. A spring can be installed to bias the counter bearing.

The print wheels each are associated with an integral gear and are mounted on a shaft with permanent magnet inserts (32, 33) to minimise friction. Each wheel has an associated wheel (7) with permanent magnet inserts (9) set to form an identification coding. A retaining latch (3) is controlled by solenoids (29,30) to move a stop bar (2) to release the print wheel. Each print wheel has such an arrangement allowing individual settings to be made.
Patent DE-3103105-A1 (DE)
Title: Electrohydraulic operating arrangement
Inventor: EBERHARDT ROLAND DIPL ING
IPC: H01H35/38
Filed: 1981-01-30
Abstract: The invention starts from an electrohydraulic operating arrangement in which a piston device is acted upon by the accumulator pressure and is spring-loaded against the pressure force. Acting on the piston device is a friction member which sets a retaining force against a piston displacement and, after a maximum accumulator pressure is reached, causes a contact mechanism to remain actuated even when the accumulator pressure drops. Since the friction member is difficult to control with regard to its action and is affected by wear and a displacement of the operating hysteresis sets in as the working life advances, the invention proposes that, instead of a frictional connection, a positive-locking connection be provided between the piston device (9) and the guide housing (1), which positive-locking connection comes into engagement only in the actuating position of the contact mechanism (7) at maximum accumulator pressure. <IMAGE>
Patent DE-3103743-A1 (DE)
Title: Load-bearing apparatus for a front-mounted facade
IPC: E04F13/08
Filed: 1981-02-04
Abstract: The load-bearing apparatus for a front-mounted facade is composed of at least one load-bearing member, which is usually mounted in the vertical direction, and of a plurality of fastening angles which are held on the load-bearing member in the longitudinal direction thereof. Their angle legs are mounted on a wall (not shown), in particular the outer surface of a building wall, to be precise with the aid of a fastening element which permits horizontal alignment and passes through the horizontally running slot. The shaft of a sliding spacer passes through a vertical slot, which spacer is fixedly connected to the load-bearing member or its T-central web. For this purpose, use is made of a fastening element, for example a blind rivet, a screw with a nut or a self-tapping screw. The length of the shaft exceeds the thickness of one angle leg, with the result that, on the one hand, the load-bearing member can be aligned in the vertical direction with respect to the angles fastened on the wall side and, on the other hand, different changes in length, caused by temperature, of the load-bearing member can be compensated for. The collar, or a different laterally projecting extension of the shaft, engages behind the surface of one angle leg without bearing fixedly thereon. This permits the abovementioned displaceability of the load-bearing member with respect to one angle leg, although the sliding spacer, as has already been said, bears fixedly on the surface of the load-bearing member. The surface facing towards the load-bearing member or the bearing surface thereof may be planar, arched or cambered. The same applies for that surface of the sliding spacer which bears on the load-bearing member, it being possible for said surface to be designed in a planar or cambered manner.

Title: Device and process for dressing grinding wheels
Inventor: LANG KARL
IPC: B24B53/08
Filed: 1981-05-25

Patent DE-3134628-A1 (DE)
Title: Switched-mode power supply
Inventor: GENSLER FRANK DIPL PHYS
IPC: H02M3/155
Filed: 1981-09-02
Abstract: The invention relates to a switched-mode power supply having a storage capacitor and having a storage inductance. It is based on the principle of the flyback converter with a variable clock sequence (pulse sequence). The parallel circuit comprising a suitably dimensioned series-resonant circuit and the semiconductor switch or the storage inductance makes it possible for the semiconductor switch to be opened at a time at which both the current flowing through it and its instantaneous rate of rise assume the value zero. Transistors and, without additional self-commutated circuits, thyristors can also be used as the semiconductor switches. In conjunction with a tuned-circuit monitoring circuit, a control circuit (regulating circuit) changes the semiconductor switch into the conductive state when required. If a transistor is used as a semiconductor switch, a protection circuit ensures that the base current or the gate voltage is not disconnected until the current minimum is reached. The replacement of the storage inductance and the series-resonant circuit inductance by a suitable transformer allows potential isolation of the input and output voltages.

Title: Grid element, in particular grass drainage element, for heavily used grass areas
Inventor: BARSTADT HERMANN
IPC: E01C9/00
Filed: 1981-10-14
Abstract: The invention relates to a grid element (1) of a flexible porous rubber-like material, which serves in particular as a grass drainage element and is formed by crossing partitioning parts (2) and chambers (3) for receiving soil and growing grass in heavily used grass areas. The grid element (1) preferably comprises polyurethane-bonded rubber granules and has in the partitioning parts (2) and on their upper edges (2e) openings (2a) and clearances or recesses (2b) to the respectively neighbouring chambers (3). Such grid elements (1) may be laid as so-called ''drainage mats'' in heavily used grass areas, such as in particular in the goal mouth of football pitches, so that the loads exerted by the feet of sportsmen using the grass areas do not act directly on the grass itself but are for the most part absorbed by the grid element (1) designed as a flexible supporting framework, so that the grass-bearing layer (4) remains protected against compaction and retains its natural pore volume. <IMAGE>

Title: Adaptive echo cancellation device for digital duplex transmission on two-wire lines
Inventor: ASCHRAFI BAGHER
IPC: H04B3/23
Filed: 1982-03-06
Abstract: The device according to the invention contains an adaptive echo canceller whose control circuit makes allowance for the strength of the correlation between the received signal and the transmitted signal. To accelerate the control process, the filter coefficients are re-adjusted in the case of a strong correlation at intervals which depend on the development of the correlation sums. In the case of weak correlation, the re-adjustment takes place at fixed, relatively long time intervals to enable precise adaptation. The correlation-dependent coefficient re-adjustment is provided by a monitoring and control circuit (32, 33) which monitors the calculation of the correlation sums and initiates a coefficient re-adjustment if either the amount of one of the correlation sums reaches a predefined value or a predefined time has elapsed since the previous re-adjustment. <IMAGE>

Title: Steam turbine
Inventor: TAKAHASHI TSUTOMU
IPC: F01D9/02
Filed: 1982-05-18
Abstract: A steam turbine contains a housing, a rotor shaft which extends in the housing, and a shutter which is arranged between the housing and the rotor shaft. The shutter interacts with the housing and forms a flow duct in between, into which operating fluid is introduced. A cooling chamber is formed between an inner surface of the shutter, adjacent to the point at which the operating steam is introduced, and an outer circumferential surface of the rotor shaft. A cooling fluid is introduced into this cooling chamber at a temperature which is less than that of the operating steam. The shutter contains inner and outer rings, each of which is split into a pair of segments. The cooling fluid is introduced into a cavity which is constructed in at least one of the inner and outer rings. In consequence, at least one of the inner and outer rings is cooled, and the thermal expansion difference in the circumferential direction between the inner and the outer rings is minimised as a result of the temperature difference between the cooling fluid and the operating steam.

Title: Advance device with disassemblable transfer bars
Inventor: YAMASHITA HISATERU
IPC: B21D43/05
Filed: 1982-08-27
Abstract: An advance device for a triaxial transfer press installation comprises two transfer bars which extend in parallel and at a distance from one another and can be moved backwards and forwards in their longitudinal direction as well as up and down and towards and away from one another, thereby transporting workpieces through a series of press stations. To facilitate the exchange of tools, each of the transfer bars comprises a plurality of segments, preferably five, which are connected releasably to one another at their ends. For dividing the transfer bars into the segments there are two synchronised double-acting cylinder arrangements (46), which are arranged at each end of the transfer-bar pair between a feed mechanism (30) for producing the backwards and forwards movement of the transfer bars in the longitudinal direction and a feed carrier (32) connected to both transfer bars and movable backwards and forwards in synchronism with the latter. The cylinder arrangements (46) are normally extended and, in this position, allow the backwards and forwards movement of the transfer bars by acting on the corresponding feed carriers (32). In a two-step contraction of the cylinder arrangements (46), each of the transfer bars is divided into the five longitudinally spaced segments. <IMAGE>
