Title: Pressure medium-operated brake system for pneumatically sprung multi-axle road vehicles with automatic starting aid
Inventor: TABORSKY JIRI DIPL ING
IPC: B60T8/18
Filed: 1987-03-03
Abstract: In the aforementioned brake systems, the front, non-driven axle can be "overbraked" due to the automatic starting aid taking effect. The object of the invention is to prevent this by simple means. An anti-lock-brake controller (10), which is controlled by the bellows pressure of the leading axle (2), is arranged in the brake pressure line branch (11) to the leading axle (2). A pneumatic control valve (13), which is controlled by the brake pressure (B2), is situated in the brake pressure line branch (12) to the power axle (3). As a result, the control characteristic of the pneumatic suspension of the automatic starting aid is transmitted to the brake system of a rear double axle assembly with leading axle (2) and power axle (3) in such a way that locking of the leading axle (2) is reliably avoided, at least in the partial load state. <IMAGE>

Title: Refrigerated display counter for foodstuffs, in particular for meat or cheese
Inventor: WAELCHLI HANS DR
IPC: A47F3/04
Filed: 1987-09-23
Abstract: In the case of this refrigerated display counter, the display area (6) is the support for the goods. Use is made of contact cooling plates (1) as display area. Underneath these contact cooling plates (1) there is formed a passage (3) for cooling air. Advantageously, there is a long cooling path for the air, so that it is not necessary to provide any cooling elements for low temperatures, on which the air moisture precipitates as hoarfrost and thus remains in the cooled air. The goods are cooled directly by contact with the contact cooling plates. The cooled air can be conveyed at low velocity, so that it falls onto the goods from above and does not flow over them, and consequently does not dry the goods out. <IMAGE>

Title: Cable distributor or junction box
Inventor: MARGREITER HANS
IPC: H02G15/18
Filed: 1987-11-10
Abstract: Conventional cable distributors and junction boxes pose great problems during the connection and the final assembly of the coaxial cable lengths. The coaxial cable lengths apply large stresses to the cable distributors or junction boxes, water-proofing and gas-sealing having to be effected at the same time by shrinking shrink sleeves onto the connections. In order considerably to improve the ease of installation, it is provided according to the invention that the connecting units (17) for the coaxial cable lengths (21) are separated from the device housing (9) itself and connected thereto by means of a flexible connecting cable (7). These connecting cables (7) are connected to the manufacturing interface (5) thus formed already during production, and the device housing (9) and at least an initial region of the connected connecting cables (7) are extrusion-coated with a joint protective sheath (20) for achieving gas-sealing. The cable distributor or junction box is suited above all for wide-band communications technology. <IMAGE>

Title: Method and arrangement for duplex telephoning
Inventor: JAKUBOWSKI JANUSZ DIPL ING
IPC: H04B1/54
Filed: 1987-12-08
Abstract: In the single-channel simplex operating mode, each subscriber can either only talk or listen depending on whether he has operated his speaking key or not. This method is to be simplified. In each subscriber station, a transition from a two-wire line (7) to a four-wire line with a transmitting path (5) and a receiving path (8) is implemented by a hybrid (6). The transmitting path contains a modulator (3) and the receiving path contains a demodulator (9). If transmitting is intended, a signal a is applied to a control circuit (15). If a detection device (10) detects a signal at the output of the demodulator (9), it outputs a signal b to the control device (15). It is only when a signal a but no signal b is present at the latter, that it outputs a signal c which activates the modulator (3).   Single-channel simplex. <IMAGE>

Title: Safety clamping device for the piston of a piston/cylinder arrangement
Inventor: BENDER MATHIAS
IPC: F15B15/26
Filed: 1988-03-26
Abstract: A safety clamping device for the piston (12) of a hydraulic piston/cylinder arrangement (10) is formed by two piston parts (14, 15) which with a margin (16, 17) enclose a guide body (18) in a bowl shape. The two piston parts (14, 15) are screwed to the guide body (18, 19) with expansion screws. An elastic ring (23) is inserted into the space between the outer surface of the guide body (18), the margins (21, 22) and the inner surface of the cylinder (11). When pressure is applied, the distance between the two piston parts (14, 15) is increased, as a result of which the expansion screws (24, 25) are extended elastically. When the pressure drops, the ring (23) is compressed by the expansion screws (24, 25) and bears against the inner surface of the cylinder (11), as a result of which the piston is locked in position inside the cylinder. The safety clamping device is used whenever certain positions of the piston/cylinder arrangement in hydraulic units must not change. <IMAGE>

Title: Axle-pivot steering system for a two-wheeled vehicle, in particular a motorcycle
Inventor: HELMS HANS-GUENTER
IPC: B62K21/00
Filed: 1988-06-21
Abstract: In an axle-pivot steering system for a two-wheeled vehicle, in particular a motorcycle, the steerable wheel is mounted on an axle pivot at the lower end of a steering arm which is held via a steering bearing in the front bearing point of a first, lower longitudinal link, which is articulated on the frame of the two-wheeled vehicle with its rear bearing point, and in the front bearing point of a second upper longitudinal link. Since the second longitudinal link is articulated, with its rear bearing point, on a component which can be rotated, as a function of steering commands, about the steering axis determined by the arrangement of steering bearings, steering moments resulting from steering commands can be transmitted to the steering arm via the second upper longitudinal link. The length ratio of the first lower longitudinal link to the second upper longitudinal link is greater than two to one, as a result of which a progressive braking-torque compensation is provided.

Title: Eccentric drive for a rotary mass
Inventor: MUELLER THOMAS DIPL ING
IPC: F16C27/06
Filed: 1988-10-19
Abstract: An eccentric drive is described for a rotary mass, having a drive device which engages at at least one point of the rotary mass and is formed by a first eccentric arrangement, and having a guide device which engages at at least one further point, arranged at a distance therefrom, of the rotary mass and is formed by a second eccentric arrangement, and having a bearing arrangement which is provided at at least one of the engagement points and is provided with an elastic bedding made of a rubber-elastic profiled ring (20) which is held between a bearing ring (5) of the bearing arrangement (1) and a bearing eye (6) of the rotary mass (4).

Title: Coated glass fibre textiles for high voltage insulation
Inventor: WICHMANN ARNOLD DR RER NAT
IPC: H01B3/00
Filed: 1988-11-11
Abstract: The present invention relates to the use of coated glass fibre textiles for producing synthetic-resin-impregnable high voltage insulators in electric motors and to an impregnable fine mica tape consisting of mica paper (G), a coated glass fibre textile base (T) and an adhesive (K) for connecting mica paper (G) and base (T). The coating material for the glass fibres comprises derivatives of chlorine-containing rubber, in particular vulcanisation products of chloroprene rubber. In the processing of coated glass fibre textiles for insulation duty, the coating serves to bind glass fragments, which results in trouble-free handleability. In the soaking of the textiles with synthetic resin, the coating improves the bonding of the resin to the glass and thus safeguards the quality and durability of the insulation. In the course of the heat treatment serving to cure the incorporated synthetic resin, degradation products of the chlorine-containing rubbers present in the coating have a catalytic effect in the curing of the resin and provide efficient acceleration of the curing process. The present invention permits a particularly simple and safe manufacture of high voltage insulators which combine high strength with excellent electrical insulation properties. <IMAGE>
Patent DE-3843280-A1 (DE)
Title: Method and device for electrical current measurement
IPC: G01R17/06
Filed: 1988-12-22
Abstract: The method is used for electrical current measurement, especially for measuring a temporally varying small current. The current to be measured is subjected by a control system to an opposite-polarity compensation current having approximately the same magnitude, the magnitude of the current to be measured being determined according to the compensation current and the measured current. A reverse-biased photodiode (15) is used for controlling the compensation current, which photodiode is controlled by an amplitude-modulated and frequency-modulated light source (14). In addition to the optical decoupling, which is achieved thereby, of the control loop this method has the advantage that, because of the linearity of the optoelectrical coupling component (14, 15), a linear measurement range of nine decades can be achieved, without it being necessary to have external changeover of the measurement range. <IMAGE>
