Title: AF railway signalling circuit - has frequency converter near rails converting rail de-coupled voltage into higher frequency
Inventor: DICKSCHEN ARNO
IPC: B61L1/18
Filed: 1980-06-27
Abstract: The rail circuit is remote supplied and monitored in relation to unearthed transmission and receiver lines, screened against external voltages. The operation takes place between the track rails and a remote transceiver module. Near the rails (G1) is mounted a converter for the frequency (f1) of the voltage decoupled from the rails into a different frequency (f2), which is preferably higher. The receiver module (E) may be coupled to the reception lines (L3,L4) via a filter, tuned to the converter output frequency. The converter may be in the form of a full-wave rectifier (ZG). In the railway signalling and track monitoring high frequencies in the 10 kHz ranqe are used. In such instances, however, the transmit and receive ends must be earthed. The present system provides an AF circuit, excluding untimely free report over a track section also with an earth connection.

Title: Fibre-reinforced aluminium(alloy) composite prodn. - by hot pressing or rolling assembly of fibres interposed between aluminium layers and brazing alloy
Inventor: GRUHL WOLFGANG PROF DIPL ING D
IPC: C22C47/20
Filed: 1980-09-08
Abstract: A fibre-reinforced composite material consists of fibres interposed between at least two layers of aluminium (alloy) clad on one or both sides with an aluminium brazing material, pref. an aluminium-silicon alloy contg. 5-12% Si and up to 10% metallic wetting promoters. The material is produced by compressing the Al (alloy) layers and the interposed fibres at between the m.pt. of the brazing alloy and the softening temp. of the Al (alloy) layers and then cooling. The method allows the continuous prodn. of e.g. silicon carbide or boron (opt. silicon carbide coated) fibre-reinforced Al (alloy) composite materials. The fibres are protected from thermal or mechanical damage and the composite is protected from oxidation by the brazing alloy which acts as an adhesion promoter so that the composite can be produced without significant deformation of the Al (alloy) layers if desired.

Title: Condensate separator for an incinerating and heating installation
Inventor: FOERSTER SIEGFRIED DR
IPC: F23J15/06
Filed: 1981-03-05
Abstract: For an incinerating and heating installation in which the combustion gas produced in a combustion chamber is cooled by a process of heat exchange to below the dew point of the combustion gas, a condensate separator is provided to separate out the condensate which arises in the cooling of the combustion gas before the latter enters the exhaust conduit of the incinerating and heating installation. For this purpose, the condensate separator is arranged directly at the gas outlet (5) of a heat exchanger (2) which cools the combustion gas to below its dew point (Figure 1). In order to achieve trouble-free passage of the combustion gas to the exhaust conduit, the condensate separator has a pivotable flow flap (14) which guides the condensate which separates out to a condensate outlet (7) and covers a gas outlet (8) leading to the exhaust gas duct except for a gap (15) between the bottom (6) of the condensate separator and the edge of the flow flap (14) to allow the exhaust gas to flow out. <IMAGE>

Title: Roller-blind-like road map for a car, motor cycle and bicycle
Inventor: KRAEMER HORST
IPC: G09B29/06
Filed: 1981-06-16
Abstract: The invention frees the driver/rider of the vehicle from awkward manipulations with folding maps and atlases. A sheet which is provided at the bottom with a grasping strip and has a map on both sides is fixedly installed under wound-up tension in a sleeve with a guide slot. For viewing, the map sheet can be pulled out to the stop and on being released it slides back in. Sheet and sleeve form an inseparable unit, namely a complete roller-blind-like map. Ready to hand and also usable one-handed, a roller-blind-like map is snapped into a short snap-action mount or into two snap-action rings. In the case of a car, a mount is attached, for example, by a self-adhesive strip to the dashboard, in the case of a bicycle, for example, by a screwed clip to the front part of the handlebar. A snapped-in roller-blind-like map can be quickly exchanged for another one, always remaining an inseparable unit of sheet and sleeve. <IMAGE>

Title: Sealing arrangement
Inventor: MARQUARDT WERNER DIPL ING
IPC: F16J15/3244
Filed: 1981-08-04
Abstract: A sealing arrangement (Figure 1) consists of a back-up ring (13) and a lip sealing ring (14) which rests by its rear end against the back-up ring. One of the lips (16) of the lip sealing ring is splayed outwards towards the gap (S) to be sealed off, where it makes contact by means of a sealing surface (17). Both rings are arranged in an annular groove (11). Formed on that side of the back-up ring (13) which is on the sealing side are a plurality of axial or radial notch-like recesses (40, 41) which allow fluid to be displaced from the intermediate space (18 or 23 and 24) to the side at low pressure and vice versa when the pressure is reversed. The radial velocity of flow along the sealing ring is reduced virtually to zero by these recesses, thereby reducing the wear on it considerably. <IMAGE>

Title: Detachable single or multiple seat with or without steering, in particular for surfboards
Inventor: PETRICK GERHARD
IPC: B63B35/79
Filed: 1981-11-27
Abstract: In the invention of the detachable single or multiple seat with or without steering, in particular for surfboards, several aspects have been decisive. With the conventional surfboard, surfing can only be carried out with the wind, and likewise relatively large areas of water must be present. If the single or multiple seat, with or without steering, is now mounted on the commercially available surfboards, the surfboards can be sailed (paddled, rowed) with this combination during a calm or in moderate wind and on small stretches of water, in particular river courses. Figure 1 shows an arrangement of a multiple seat with steering. Seats (1) are mounted on the surfboard (6). The seats (1) are connected by means of a linkage (2). Attached to the front linkage part (7) is a fixing bolt (3) which engages in the mast hole (8). The rear part of the linkage (7) is fastened by a holding element (4). The foot rests (2) are at the same time foot controls for the rudder (5). <IMAGE>

Title: Device for sorting bottles or the like in an upright position
Inventor: GAU GEORG ING GRAD
IPC: B65G21/20
Filed: 1982-02-06
Abstract: In a device for sorting bottles in an upright position, having a horizontal conveying surface (2), the guiding surface, which lies opposite a controllable deflector (7) and is formed by a guide rail (8) or a circulating belt (10, 18), is provided with an inclined interception area for the bottles, said area being located laterally next to the conveying surface. Said interception area is constructed in such a way that the bottles diverted by the deflector can tilt away over the edge of the conveying surface and then be intercepted in a stable oblique position by the guiding surface together with a support element (2) which engages on the bottom of the bottle. The interception area of the guiding surface is adjoined by a repositioning area which returns the departing bottles to the normal upright position on the conveying surface, the transport of the bottles in the interception area and in the repositioning area being carried out by the edge of the conveying surface and/or by the belts. As a result, even in the case of extremely intensive production and changing operating conditions bouncing back or tipping over of the departing bottles is prevented. <IMAGE>

Title: Method and device for determining the surface temperature of solid bodies
Inventor: BEHRENS WERNER
IPC: G01K13/04
Filed: 1982-05-28
Abstract: The surface temperature is determined by a differential thermocouple by using the thermal e.m.f. produced by the temperature difference to control a heating fan so that the generated gas flow brings the surroundings of the reference thermocouple point to a temperature such that the temperature difference vanishes. In order to be able to carry out a temperature measurement in a contactless fashion in conjunction with response times that are as short as possible, the means for transmitting the temperature are provided as a stream of gas which flows through the measurement space over the surface of the solid body and whose temperature is measured at the inlet and outlet of the measurement space.

Title: Wheel suspension
Inventor: THEVIS PETER
IPC: B60G11/22
Filed: 1982-06-09
Abstract: According to the invention, an effective wheel suspension in particular for lightweight two-wheeled vehicles is provided with the following features: it is     - lightweight   - compact   - economical   - easy to produce. The wheel suspension is mounted in the wheel hub. A hollow cylindrical hub-internal body is spring-mounted and guided via spring elements and guide elements on the axle body which is fixedly connected to the fork. On the outer casing of the hub-internal body, a hub-external body is rotatably mounted, said external body bearing the drive pinion(s) and being connected to the rim or to the tyre via the spokes. By correspondingly shaping the guide elements, disadvantages in terms of kinematics, which have arisen as a result of spring deflection and rebound of the wheel can be avoided. With the aid of adjustable spring elements (such as e.g. cushion-type pneumatic spring), the spring effect can be matched to the load state of the two-wheeled vehicle.
