Patent DE-3148944-A1 (DE)
Title: Device for supporting a body magnetically
Inventor: INNERHOFER GUENTHER DIPL ING
IPC: G05B6/02
Filed: 1981-12-10
Abstract: An electromagnetic support for supporting a body, for example a flywheel, without touching it, has a plurality of translational controllers. These controllers have a PID characteristic, are driven by an actuating sensor and emit an actuating signal to an electromagnet. According to the invention, the controller consists of an operational amplifier with a complete resistor network, the integrating section being formed by the elements (R1, C1) and the differentiating section being formed by the elements (R2, R3, R4, C1, C2). Bandwidth limiting is characterised by two corner frequencies, the first corner frequency being formed by the elements (R4, C2) and the second corner frequency by the elements (C3, R2, R3). The invention is primarily distinguished by a small component cost. <IMAGE>
Patent DE-3149953-A1 (DE)
Title: Demodulation method
Inventor: MENNING JOERN ING GRAD
IPC: H03D3/04
Filed: 1981-12-17
Abstract: In a demodulation method for frequency-modulated radio-frequency signals, a direct-current signal corresponding to the carrier frequency is generated. In order to allow the direct-current signal to follow the respective carrier frequency quickly, the duration of the period of the carrier frequency is derived from the radio-frequency signal and converted into a direct-current pulse. In the period, the direct-current pulse controls an integrator to a voltage value proportional to the duration of the direct-voltage pulse. During the next period, this voltage value is loaded into a storage circuit as the direct-voltage signal, and the integrator is reset.
Patent DE-3201360-A1 (DE)
Title: Device for injecting a prestressing member, especially an individual prestressing member
IPC: E04G21/12
Filed: 1982-01-19
Abstract: For injecting a prestressing member made of a steel bar (2) equipped with a thread, use is made of a bell-like housing (15) which encloses the outer anchoring parts. The housing (15) has, in its upper region, a perforation (16), with which it can be pushed over the end of the steel bar (2) and fixed by a nut (20). It is sealed in the region of this perforation (16) by means of a sealing ring (18) with respect to the steel bar (2) and at its lower edge by means of a sealing ring (22) with respect to the anchor body (4). The contact pressure required for the seals to take effect is built up via the steel bar (2) itself, so that no additional measures are required. By virtue of the fact that the housing (15) is left within the usual recess for anchoring in the concrete, reliable corrosion protection is ensured even at the externally located anchoring parts, if gaps should arise between the sealing material to be introduced subsequently into the recess and the wall of the recess, owing to shrinkage of the sealing material. <IMAGE>
Patent DE-3208554-A1 (DE)
Title: Brake calliper for motor vehicles, with supply of rust dissolver or anti-seize agent to prevent the rusting solid of the brake pistons and to facilitate repair
Inventor: ELMSHAEUSER REINER
IPC: B60T17/18
Filed: 1982-03-10
Abstract: When cars are not used for a short time, the brake pistons in the cylinder guide acquire a light coating of rust. During repairs to the disc brakes, the brake calliper is therefore generally renewed, something which would be unnecessary if the pistons were movable, in order to save costs. The invention intends to avoid this accumulation of rust. This is effected by providing on the brake calliper an introduction point via which a rust-preventing or anti-seize agent is automatically introduced to the location subject to the threat of rust, an accumulation of rust thereby being prevented. According to the invention, it is possible to substitute for the fixed feed means an injector, during brake repair, which is plunged by means of the needle into the sleeve provided in order to introduce the rust-preventing or anti-seize fluid manually into the cavity of the sleeve. This makes repair easy and less expensive. It also provides a higher degree of safety since it is not possible for a brake piston to seize during a journey either.

Patent DE-3220182-A1 (DE)
Title: Electrical isolating joint for AC-fed track circuits
Inventor: WALTER HEINRICH
IPC: B61L1/18
Filed: 1982-05-28
Abstract: The subject-matter of the invention is an electrical isolating joint for track circuits fed by AC and free from insulated joints, which enables the particularly sharp transition from one to the other monitored track region. This is achieved by using as cross connector a so-called S-connector whose terminals are retracted as far as the centre of the isolating joint. The signals are coupled out by means of coupling loops whose linear extent is substantially smaller than that of the cross connector. The coupling loop can also have a plurality of turns. Transition regions and overlap regions of differing linear extent are produced by different configuration of the coupling loops and shaping of the cross connector. <IMAGE>
