Patent DE-3733525-A1 (DE)
Title: Device for the aeration and deaeration of shafts, containers, rooms or the like loaded with harmful gases
IPC: E03F5/08
Filed: 1987-10-03
Abstract: On account of the constructive design of the known devices for the aeration and deaeration of shafts, containers, rooms or the like loaded with harmful gases, a desirable mobile use of the devices was impossible. On the one hand, these devices were very heavy and cumbersome and could therefore only be moved laboriously by a single person, and on the other hand the operation of the blower required a permanently installed electrical connection. In contrast to this, the device according to the invention is designed so that the blower (7) can be driven by means of a direct-current motor (8) operable at low voltage. This direct-current motor (8) can be connected to any low-voltage source, for example to a battery or to a cigarette lighter of a motor vehicle. Furthermore, the blower has a suction connection (10) and a delivery connection (9), onto each of which a flexible hose (2) can be selectively slipped. A measuring device (11) measuring the gas concentration of the sucked-up air is arranged between the suction connection (10) and the hose (2). Furthermore, according to the invention, there is provided at least one container (16), into which the hose (2) can be deposited when not in use. The blower (7), direct-current motor (8) and container are arranged within a portable housing (15). <IMAGE>

Title: Device for wiping motor-vehicle windows
Inventor: KUEHBAUCH GERD DIPL ING
IPC: B60S1/36
Filed: 1987-12-05
Abstract: The invention relates to a device for wiping motor-vehicle windows, in which the oscillating wiping movement, taking place between two reversal positions, of the wiper blade lying on the window is combined with a sliding movement which is directed transversely to the oscillating movement and in the longitudinal direction of the wiper blade and takes place between the two reversal positions. In the case of a device of this type it is proposed to provide two separate, primary movement-generating systems, to use the output variable of one of these movement-generating systems, which can be driven by a common driving motor, directly for the realisation of the basic movement, for example a swivelling and oscillating movement, to be carried out by the wiper arm, and, at the same time, to feed this movement and the movement of the other primary system to a differential gear, the output variable of which serves to generate the other basic movement of the wiper arm, for example its stroke movement. <IMAGE>

Title: Ornamental band of synthetic resin and method for its production
Inventor: MIYAKAWA NAOHISA
IPC: B44C5/04
Filed: 1988-01-25
Abstract: An ornamental band (10) of synthetic resin comprises a base strip (11), at least one decorative strip (12) which rests on the base strip (11) and is a colour which differs from that of the base strip (11), and a coloured or colourless transparent covering layer (14) which rests on the decorative strip (12) and the base strip (11), the mutually opposite ends being treated so that a pleasing appearance is imparted to the ornamental band. The end regions of the ornamental band (10) are formed by cutting out the base strip from the ends, shoulders being formed in each case. The shoulder region is warmed from the underside in order to soften the material, whereupon the end region is pressed down into the base plane of the base strip (11). Adhesive strips along the longitudinal edges of the band (10) serve to fix it to the outer surface of motor vehicles, furniture items and the like. <IMAGE>

Title: Collision guard for the probe of a coordinate measuring machine
Inventor: JOOSS GERD DIPL ING
IPC: G05B19/4061
Filed: 1988-02-11
Abstract: As collision guard, provision is made of a pressure-medium element which loads a defined force onto the probe, which is suspended in a flexible (compliant) holder. This pressure-medium element in the form of a diaphragm (10) filled with compressed air is connected to a valve (19) which opens in the event of a collision and reduces the bearing pressure in the process. In addition, a device (6a-d) is provided for relieving the weight of the probe. In the event of a collision, static reaction forces therefore do not occur, and the probe can easily give way to the obstacle. <IMAGE>
Patent DE-3806574-A1 (DE)
Title: Device for metabolic control
Inventor: WAGNER WOLFGANG DR MED
IPC: A61M5/172
Filed: 1988-02-26
Abstract: A device representing a further development of the features and functions described in Laid-Open Application WO 86/01728, as a supplementary application to DE P 3708031.8, in which reliable adhesion to the skin (even in the presence of interfering influences such as a large amount of body hair) is ensured, preferably with the use of a suction cup, in that a device for measuring the air pressure conditions prevailing in the region of the suction cup is employed for restoring the requisite reduced pressure by activating a vacuum pump when the pressure rises; where puncturing is intended, injuries to the skin are to be kept as small as possible, and this can be achieved by subsequently extending the incision by vibrations of a lancet, where an optical control device monitors the adequate filling of the reaction or measuring chamber. Many other functions are also improved: for example, optical monitoring of the skin in order to avoid puncturing of diseased skin parts, release of the skin to be drawn into the suction cup by control of the suction cup pressure by balancing springs, the puncturing styles, the cannula or style exchange, the tube-integrated metering device and the injection device, to mention just the most important functions.

Patent DE-3814922-A1 (DE)
Title: Fifthwheel coupling
Inventor: JAKOB LOTHAR
IPC: B62D53/12
Filed: 1988-05-03
Abstract: The invention relates to a fifthwheel coupling with a fifthwheel pick-up plate which has a coupling jaw, which ends in a central recess, for a kingpin of a semitrailer and bears locking elements for the said kingpin which are coupled to the fifthwheel pick-up plate, one of which locking elements is constructed as an approximately V-shaped coupling claw which is arranged pivotably in the fifthwheel pick-up plate whilst the other locking element is a lever which can be pivoted in the fifthwheel pick-up plate and has a locking projection which can be engaged with the coupling jaw. So that the fifthwheel pick-up plate is of simpler design and easier to actuate, there is provision for the leg of the coupling jaw which trails when the kingpin is inserted to have an annular cutout-shaped supporting face on the outside in the end region, which supporting face can be engaged with the corresponding locking projection of the lever, the counterstop being provided on the fifthwheel pick-up plate with a guide face for the locking projection on the side facing away from the supporting face and the single-arm lever being coupled virtually free of lateral forces to the widening section of the coupling jaw.
Patent DE-3819928-A1 (DE)
Title: Motor vehicle rear axle
Inventor: BEDUHN HARALD DIPL ING
IPC: B60G3/00
Filed: 1988-06-11
Abstract: The suspension links of known motor vehicle rear axles are sometimes articulated on the vehicle body so that they are longitudinally flexible by appropriate design of their body-side bearing; due to the longitudinal suspension effect thereby obtained, the comfort (noise transmission) is improved, especially when running over obstacles (for example potholes). The longitudinal suspension effect is generally achieved by means of rubber-elastic elements arranged in the body-side bearings which, however, leads not infrequently to impairment of the bump steering behaviour. In order to obtain a comfort-enhancing longitudinal suspension effect without adversely affecting the bump steering behaviour, the wheel carrier in the new motor vehicle rear axle is not articulated directly on the suspension link but by way of a swivel lever, the swivel-lever axis running transversely to the vehicle's longitudinal axis and lying more or less diametrically opposite the wheel contact point.Between each swivel lever and suspension link a bilaterally acting spring device is arranged, by means of which the unloaded swivel lever is held in a centre position, and the spring device and swivel lever are dimensioned in such a way that the maximum amount by which the swivel lever can be swivelled out of the centre position is such that the centre position that the wheel axle in turn is deflectable by a maximum of approximately +/- 40 mm. <IMAGE>

Title: Thermally generated hydrogen from hydride reservoir - for redn. of metal salt or gas, esp. for purifying waste gas
IPC: F02B3/06
Filed: 1990-02-21
Abstract: Hydride is expelled from a reservoir thermally for redn. i.e. atomic or mol. hydrogen is used for regulated oxygen absorption and also in more than stoichiometric amts. for waste purificn. relevant to the environment, with simultaneous influence of the regulated reaction-kinetic catalytic reaction temp. - Hydride is burnt above a (diffusion) burner not producing NOx to burn incombustible substances in the waste gas stream. The harmful impurities are reduced catalytically after the diffusion burner. More than the stoichiometric amt. of hydrogen is supplied through the diffusion burner to reduce the NOx in the waste gas to N2 and H2O. Combustion of the waste gas pref. is carried out in 2 cycles. Soot is burnt on starting the engine, since Fe titanate hydride releases hydrogen to the diffusion burner at +40 deg.C. A solid mixed hydride reservoir is used for optimum waste gas purificn. at start up and during running. The hydride solid from the container is replaced by a new hydride solid after emitting the hydrogen without the need to replace the container or fitting oper.ations.
