Title: Optical arrangement for electro-optical range finders
Inventor: FEIST WIELAND DIPL ING DR
IPC: G01C3/00
Filed: 1983-05-30
Abstract: The invention relates to an optical arrangement for electro-optical range finders, which can be used in simple distance-measuring instruments or electro-optical tachymeters and for all geometric and physical beam divisions. The optical system of the electro-optical range finder is designed in such a way that only one telescope is used for all three beam systems and that, with a free optical axis, a beam division of the infrared transmitting and receiver beam paths is effected biaxially with respect to one another and at the same time coaxially with respect to the visual telescope beam path, at the same time reducing the number of optical components, increasing the degree of transmissivity, the measuring range and the image quality. In the image plane of the lens along the optical axis, only one reflection system is located which represents a plane-parallel plate of optical glass and consists of at least two individual parts, two surfaces of each individual part being arranged in wedge form with respect to one another for the geometric beam division and only one surface of the wedge surfaces of the individual parts, opposite one another within the plane-parallel plate, being covered with a reflecting layer for the physical beam division. <IMAGE>

Title: Hinge structure for the formation of a unitary movable warming-cabinet system
Inventor: DELUCIA PAUL V
IPC: E06B3/48
Filed: 1983-12-14
Abstract: The invention relates to a hinge structure for the formation of a unitary movable warming-cabinet system having panels which can be displaced from a closed operating position into an open or inoperative position. Movable warming cabinets are already known but these have the disadvantage that they are not leak-tight throughout, particularly at the panel joints, allowing heat energy to escape through the openings which are present. The object on which the invention is based is to provide a hinge structure for a unitary warming cabinet by means of which these disadvantages can be eliminated and which also offers better resistant to losses of heat energy. The object is achieved by virtue of the fact that the hinge structure, composed of thermally insulating material, comprises an outer, elongate hinge element (12) which is in the form of a hollow sleeve (14) and which forms an essentially open joint-socket element (17) with an opening angle less than 180 DEG  and has an inner elongate hinge element (13) which forms at least one insert resting with a press fit in the joint-socket element (17), rotatable in the latter and guaranteeing uninterrupted thermal insulation of the adjoining panels. <IMAGE>

Title: Device for limiting rolling movements of a vehicle with bolsterless pneumatic spring bogies
Inventor: MOHACSI SANDOR DR ING
IPC: B61F5/24
Filed: 1983-12-22
Abstract: Rail vehicles with pneumatic suspension tend to experience rolling movements as a result of the flat spring characteristic curve. The said rolling movements have to be limited in the interests of safety. According to the invention, a spring element 11 is installed between the intermediate element 4 which can be designed as a composite rubber/metal spring 6 and the bellow plate 5. This spring element is effective when the rolling movement exceeds the value "a" and subsequently damps the further rolling movement in an elastic manner. In an extreme case, the rolling movement assumes the value consisting of the sum of "a" and "b". In this case, the rolling movement is restricted by the first spring plate 9 striking against the second spring plate 10. <IMAGE>

Title: Flexible polyimide multilayer laminates
Inventor: KUNDIGER ERNST F DIPL CHEM
IPC: H05K3/02
Filed: 1984-06-30
Abstract: The invention relates to laminates with layers of fully aromatic polyimides which are no longer shapable and are each bonded directly at one side to a layer of backing material. Two laminated bodies thus obtained are bonded together by means of heat-sealable polyimide on the layers of polyimide which is no longer shapable. The multilayer laminate thus obtained represents the basic body of the laminates according to the invention at the exterior surface(s) of which further layers can be joined. The laminates can be produced by a process which is also claimed in which heat-sealable polyimide or the precursor thereof is applied to polyimide which is no longer shapable, before or after it is completely cured. Subsequently the layers are bonded at elevated temperature, if appropriate after a curing stage. The backing materials are preferably metal or alloy foils. The resulting multilayer laminates are distinguished by outstanding mechanical, thermal and electrical properties. They can be used as reinforcing materials and for printed electrical circuits.

Title: Antilock brake system
Inventor: SATO MAKOTO
IPC: B60T8/66
Filed: 1984-08-06
Abstract: An antilock brake system with a wheel brake, a circuit for controlling the supply of a hydraulic pressure to the wheel brake, a wheel speed detector and a decision circuit, which is provided in order to emit a brake pressure reduction signal and a brake pressure increase stop signal to the hydraulic pressure control circuit according to a determined value which is emitted from the wheel speed detector, which is characterised in that a filter circuit, which permits the passage of a brake pressure reduction signal only if its pulse duration is not less than a predetermined level, or only if its frequency is not higher than a predetermined value, is connected to the output terminal of the decision circuit for supplying the brake pressure reduction signal. Even if a brake pressure reduction signal is emitted from the decision circuit owing to the pulsation of the wheel speed, which pulses are caused by vibrations of a suspension system which occur when a vehicle is travelling on a bumpy road, the signal is transmitted to the hydraulic pressure control circuit, thereby preventing an undesirable increase in the braking distance.

Title: User terminal for video telephony
Inventor: KOEHLER GUENTER DIPL ING
IPC: H04N7/14
Filed: 1984-08-30
Abstract: Such a user terminal exhibits, among other things, a video camera (2) and an image display device (3), for example a television set. Since the video camera (2) and the picture tube of the display device are not arranged on the same optical axis, the viewing angle for the user is wrong. To avoid this, a semitransparent mirror (6) is inserted into the beam path (4) between the video camera (2) and the position of the user (5). This mirror deflects the rays coming from the image display device (3) in such a manner that their direction corresponds to the direction of the beam path (4) between the video camera (2) and the user (5). <IMAGE>
