Inventor: KUETTENBAUM VALENTIN
IPC: A63C17/01
Filed: 1988-04-06
Abstract: The sporting device (1) in the form of a rolling and sliding device consists of a baseplate (2) and support members, for example in the form of rollers (5, 6, 7, 8), mounted on said baseplate by means of full floating axles (3, 4) arranged opposite each other. The baseplate (2) is provided with a gripping piece (21) as a tilting or steering aid which is rigidly connected to the baseplate (2), and by means of which the baseplate (2) can be inclined laterally. By this design, a sporting device (1) is provided which offers the advantages of a skateboard, but can be ridden without difficulties and used in a very varied manner. Above all, there is a high degree of safety when riding it and accidents and injuries caused in them to the rider are largely avoided. The technique of riding a sporting device of this type, which is composed of few components, is also easy to learn in order to handle it safely at all times, specifically also when used in different ways. <IMAGE>

Patent DE-3817440-A1 (DE)
Title: Bus-bar
Inventor: WIESEMANN ULRICH
IPC: H01R25/16
Filed: 1988-05-21
Abstract: A bus-bar has a casing-like conductive channel made of a metal section or plastic section, along the inner side of which two or more metal conductors are arranged parallel to each other. Using these, adaptors for current supply and/or collection can be coupled. In order to improve the contact-making by means of a reliable contact pressure, the metal conductor contact bars, in which contact bushes are formed in grid spacings to receive contact pins of the adaptors, are [lacuna]. The contact bushes have at least two sleeve sections which are arranged on spring webs formed by the contact bars themselves. When the webs are moved apart by the contact pins of the adaptors, the contact pressure is applied with elastic deformation of the spring webs.

Title: Fruit-tea cream chocolates (bars, blocks and the like)
IPC: A23F3/32
Filed: 1988-06-24
Abstract: A novelty from the confectionery sector, in this case: fruit-tea cream chocolates. The ingredients for the tea are in this case, as desired, tea     with sugar/sweetener and   (concentrated) fruit/fruit addition and/or   vitamins of fruit/fruits in addition, the cream filling composition from ingredients as desired.   If the fruit extracts are to be dispensed with and only vitamins provided, the fruit flavour must be produced artificially; however, it must possibly be further reinforced in the case of fruit extracts.   In accordance with the desired taste, greater or lesser amounts of the individual ingredients are selected to produce the base mass. With respect to tea, the caffeine (theine) content is balanced, if necessary by removal or addition of caffeine, depending on taste and requirement. Further ingredients which lead to a rounding off of flavour, are possible, and in addition enhancement to achieve a particular component as a "highlight".

Filed: 1988-07-19
Abstract: A pipe shunt for a two-cylinder pump for viscous fluids contains a swivelling pipe (2) with a turned groove (6, 8) in the form of a right-angled step at its front end which receives an elastic rubber ring (3). The radial outer surface of said ring rests against the part of the turned groove (6, 8) which bridges the axial guiding surface (21) of an abrasion ring (1) and the front face (12) of said ring rests against the axial inner surface (17) of a ring shoulder (22) arranged on the abrasion ring (1). The radial inner surface of the elastic rubber ring (3) bridges a gap between the abrasion ring (1) and the swivelling pipe (2) and rests against the radial limiting surface (8), and the rear surface (12') of the elastic rubber ring (3) rests against the axial limiting surface (6) of the turned groove in the swivelling pipe (2). The abrasion ring (1), which is axially mobile on the swivelling pipe (2) and can be adjusted by means of the elastically pretensioned ring (2), is thrust by means of the hydrostatic internal pressure in the swivelling pipe (2) against a bridge plate (5), before the swivelling pipe (2) can be swivelled so that orifices (4) communicating with the delivery cylinders of the pump for viscous fluids communicate alternately with the swivelling pipe (2) and with a fluid dispenser.

Title: Air intake system
Inventor: SNITIL BERNHARD DIPL ING
IPC: F02M35/12
Filed: 1988-09-22
Abstract: The intake connection (4) of an air filter (1) opens into a flask-shaped prechamber (5), which is capable of drawing air in by way of a flask neck (7) lying opposite the said opening. Despite possible reduction of the cross-section of the intake connection (4) and considerable reduction of the intake noise, the prechamber (5) does not result in any essential reduction of the power of the internal combustion engine, but rather even in a power increase in certain engine speed ranges if the prechamber volume is dimensioned correctly. <IMAGE>

Inventor: SCHULTZ HORST DIPL ING
IPC: A47J27/62

Patent DE-3904858-A1 (DE)
Title: Method and device for controlling a melt bath
Inventor: DRECHSEL DIETER DR
IPC: C30B29/06
Filed: 1989-02-17
Abstract: A method and a device are proposed for controlling a melt bath, in particular a melt bath for growing single crystals or bodies consisting of a plurality of crystals. The measured value from a triangulation with the aid of a measuring light beam is used as actual value for the control. The measuring light beam emitted by a light source (18) impinges on the moving surface (21) of the melt bath. Because of the movements, reflection angles varying with time occur. Because of this, a plurality of measuring light beams (22, 23, 24) are reflected from one point of the surface of the melt bath. They pass through a line filter (35) which is transparent only for light of one wavelength. They are focused by means of a focusing optics unit (36), specifically on the image plane (37) which is designed as the sensing surface of a continuously position-sensitive sensor. The position of the point-shaped image on the sensing surface is determined only by the vertical position of the surface of the melt bath. A chopped laser beam can be used as measuring light beam. By means of the invention, good preconditions are provided for a rapidly-reacting and precise permanent control of the desired level and/or the desired configuration of the surface of the melt bath. <IMAGE>

Title: Mechanical gearshift arrangement for change-speed gearboxes of motor vehicles
Inventor: WELKE HELMUT
IPC: F16H61/34
Filed: 1989-03-18
Abstract: In the case of known mechanical gearshift arrangements which are used to bridge relatively large distances between the driving control position and the change-speed gearbox - lorries with tiltable cabs - gearshift devices are known, for example, which, to achieve the necessary gearshift movement, have considerably cranked transmission linkages to obtain a rotational and axial movement of the selector rod. For the necessary rigidity of the transmission linkage, they must be of large dimensions owing to the cranking. To reduce the space requirement of the transmission linkages, provision is made for the movement direction of the gearshift lever 3, 4 into the pivoting region and from two respective angle levers 13, 14 and 21, 22 arranged at right angles on the gearshift lever 3, 4 to be transmitted via separate respective transmission linkages 11, 12 and 15, 16 to respective toggle levers 31, 32 and levers 23, 24, to turn the selector rod 39, 40 about the longitudinal axis 25, 26 or to displace the selector rod 39, 40 in the longitudinal direction. The mechanical gearshift arrangement enables exact transmission of the actuating movements triggered by the gearshift levers 3, 4 to the selector rod 39, 40, with the components at the same time requiring little space. <IMAGE>
