Title: Displaceable marking device for calenders
Inventor: IWATA SHUJI
IPC: B42D5/04
Filed: 1982-09-01
Abstract: A displaceable marking device for calenders comprises a marking plate, a guide magnet attached to the marking plate, a carrier magnet attached to a backing plate and connecting means. The marking plate is arranged so as to be displaceable on the front of a calender sheet, whereas the carrier magnet is mounted on the back of a calender sheet in a position corresponding to that of the guide magnet attached to the marking plate. The marking plate has a window through which a number representing a date on the calender sheet is visible. During the manual displacement of the marking plate on the calender sheet from one number to another, the carrier magnet, attracted by the guide magnet through the calender sheet follows the marking plate. As a result, a date on the calendar sheet can be marked.

Title: Radio system for data transmission with transceiver stations moving along predetermined paths
Inventor: LA FUENTE PEDRO DE DR ING
IPC: B61L3/12
Filed: 1982-10-01
Abstract: Radio system for data transmission between transceiver stations (FZ) moving along predetermined paths and fixed transceiver stations (OF) disposed along the path which are combined to form transmission sections and are connected via cables to a central station (Z), different data being transmitted in different transmission sections and a radio frequency change taking place. The cable is a four-wire cable (AP1, AP2) which is laid from the central station (Z) along the path. The fixed transceiver stations (OF) are connected to a first wire pair (AP1) of the cable, and the first wire pair is terminated (A) in each case at the interfaces between transmission sections (n-1, n, n+1). The central station (Z) is connected to a second wire pair (AP2) of the cable, in which the data transmission is carried out in frequency-division or time-division multiplexing between the central station (Z) and the different transmission sections (n-1, n, n+1). The first wire pair (AP1) is coupled in each transmission section (n-1, n, n+1) via a branch (Z12-Abzw.) to the second wire pair (AP2) (Fig. 1). <IMAGE>

Title: Water flow unit
Inventor: ROEHRDANZ EDWIN
IPC: F03B17/06
Filed: 1982-11-10
Abstract: A device for acquiring energy, which can be used in particular in quickly flowing water courses, consists of two water wheels to which the required drive water is fed via a baffle or a water funnel in a selective manner and with simultaneous banking-up of the water level. One of the two water wheels can be eliminated by means of the baffle or by raiseable and lowerable gates so that operation is ensured even with small amounts of water, for example in the summer. The individual water wheels, several of which can also be provided in combination in the direction of flow and at a distance from one another in a river course of this kind, are connected via suitable gears to a generator in order to acquire electrical energy from the acquired mechanical energy. The necessary investment and operating costs are so advantageous due to the simple design and the small degree of constructional work required that even relatively small amounts of acquired energy are available at favourable prices. <IMAGE>

Title: Method for producing a two-terminal three-phase current winding
Inventor: WIESER FRITZ
IPC: H02K15/06
Filed: 1982-11-20
Abstract: The invention proposes a method for producing a two-terminal three-phase current winding which, in contrast to manual production, which was the only possible way in the past, can be carried out in one procedure with the aid of a drawing-in device. This is achieved in that the individual coils are formed with a straight top and limbs which run conically outwards and downwards and merge into a circular bottom, and all coils of a coil group are jointly inserted into a drawing-in device of a known type, the coils, which extend over an angle of 180 DEG , being moved into their position on the side which is common to the whole coil group, within the drawing-in device, with the aid of a deflection finger which can be plugged on, is curved out from the centre and whose position is variable, and in that the three coil groups of the winding are incorporated in the stator in one drawing-in process by means of a thrust part which supports each individual coil group separately and is equipped with three levels at different heights.

Title: Aerodynamic aid, especially front and/or seat fairing of a motor cycle and process for the manufacture thereof
IPC: B62J17/00
Filed: 1983-03-25
Abstract: An aerodynamic aid for a motor cycle, especially a front and/or seat fairing consists of a laminate in which a fibre material of aramid fibres or carbon fibres is preferably embedded in an epoxy resin.

Title: Process for the production of silicon carbide fibres
Inventor: LEVACHER FRIEDRICH KARL DR
IPC: C23C16/32
Filed: 1983-11-10
Abstract: The process of pyrolytic deposition from the gas phase uses a reaction chamber (8) through which a core wire of tungsten has hitherto been drawn and heated by the passage of current. This produces relatively expensive SiC fibres. They become significantly cheaper if the core wire used is a glass fibre (5) drawn at the top of the reaction chamber from a preform (1) of relatively large diameter to a diameter of about 10  mu m, as is known in the production of optical waveguides (optical fibres). <IMAGE>

Title: Antilock brake control system with a plurality of independently functioning digital control units
Inventor: KUBO JUN
IPC: B60T8/96
Filed: 1984-05-09
Abstract: The antilock brake control system according to the invention comprises a plurality of control units, by means of which the brake pressure on corresponding vehicle wheels is controlled. Each control unit receives wheel speed sensor signals from a corresponding wheel speed sensor and derives the speed of the corresponding wheel or wheels. The control unit detects errors or any failure of the wheel speed sensor in order to perform an additional safeguard operation and in order to continue the brake control. The control units are independent of one another in relation to the antilock brake control, but function together with one another in relation to the additional safeguard operation should one of the wheel speed sensors fail. The additional safeguard operation involves shifting the operating mode of the brake system of the vehicle from the controlled operating mode into a manual operating mode. Changing of the operating mode from the controlled operating mode into the manual operating mode is carried out in each control unit with a predetermined time control.
Patent DE-3419145-A1 (DE)
Title: Electrical cable
Inventor: RANDOLF HEINRICH LUDWIG
IPC: H02H5/10
Filed: 1984-05-23
Abstract: An electrical cable having a plurality of insulated main cores, which are possibly surrounded by a common insulating sheath, which cable at one end contains a plug element for connection to a voltage supply, has at least one further protective core along the cable and a relay which isolates the main cores from the voltage supply in the event of a protective core being cut through. In order to ensure reliable isolation of the main cores from the voltage supply with a low energy consumption, if the cable is damaged and the protective cores are at the same time cut through, all the protective cores are earthed and are individually connected to the inputs of a gate circuit which places the relay in the switched-off state if a protective core is cut through.

Patent DE-3507484-A1 (DE)
Title: Hydraulic brake system
Inventor: BURGDORF JOCHEN
IPC: B60T13/14
Filed: 1985-03-02
Abstract: In a hydraulic brake system comprising a pedal-operated brake booster (5) connected to the master cylinder (3) with a booster piston (4) and a booster chamber (7), in which a servo pressure proportional to the foot force (F) is adjusted by way of a brake valve (6), a filling stage cylinder (18) is provided, from which a certain amount of pressure medium is fed into the master cylinder (3) during the braking process if the brake booster (5) is intact. For this purpose the pressure chamber (21) of the filling stage cylinder (18) is connected to the booster chamber (7) by way of lines (24, 32), into which a multi-way valve (34, 37, 51) and a non-return valve (36) are inserted. Should the booster fail, the pressure medium already fed from the filling stage (22) of the filling stage cylinder (18) into the master cylinder (3) cannot flow back since following actuation of the multi-way valve (34, 37, 51) by way of the levers (59, 62) coupled to the brake pedal (46) the pressure medium present in the pressure chamber (21) of the filling stage cylinder (18) cannot escape from this and thereby locks the two-stage piston (20), which separates the filling chamber (22) from the pressure chamber (21). <IMAGE>
