Patent DE-3712323-A1 (DE)
Title: Washing-agent flush-in device
Inventor: AUGUSTIN SIEGFRIED DIPL ING
IPC: D06F39/02
Filed: 1987-04-11
Abstract: Washing-agent flush-in devices for adding pulverulent and/or liquid washing agents, which work on the generally known siphon principle, have the disadvantage that clogging occurs at the entrance of the suction channel when high-viscosity treatment agents are added. In the new washing-agent flush-in device, even high-viscosity and/or pulverulent treatment agents are flushed out of the washing-agent chamber reliably. The siphon (2) is formed by a stationary pipe part (3) and a pipe part (4) mounted movably on the latter and having a formed-on buoyancy body (7). Located in the stationary pipe part (3) is the overflow channel (5), through which the mixture of water and washing agent is flushed into the treatment space of the machine. The buoyancy body (7) brings about a change in position of the pipe part (4) with a rising or falling liquid level (8) in the washing-agent flush-in chamber (1), and consequently the entire liquid, with the exception of a slight residue, is sucked out of the washing-agent chamber (1). The design of the washing-agent flush-in device is suitable for adding high-viscosity and/or pulverulent treatment agents in washing machines or dishwashers. <IMAGE>

Title: Cam mechanism with constant transmission ratios for restricted spaces
Inventor: KOOP FRANZ
IPC: E21B4/00
Filed: 1987-04-11
Abstract: Cam mechanism with constant transmission ratios for areas in which the space is restricted radially. In the known cam mechanisms (sinusoidal ball mechanism), unfavourable force relationships occur during torque transmission and these have a disadvantageous effect on the loading capacity of the mechanism. The new arrangement is to be capable of bearing significantly higher loads for approximately the same radial overall size. In this arrangement, the two cam sleeves (1 and 3) are arranged coaxially in series. The cam grooves are linear over large areas so that the transmission angles are largely constant. Engaging in the cam grooves are the running rollers (2c), which are mounted rotatably on the slides (2a) by means of shaft journals (2b). In order to permit the oscillation along the cam functions, the slides are guided in axially displaceable fashion in the shaft (2). There is a free choice of input and output members, according to the desired transmission ratio. By virtue of the cylindrical/coaxial hollow construction with its high loading capacity and smooth running, the mechanism has numerous areas of application, especially in radially restricted spaces, for example in the natural-gas and oil industries as a drilling-turbine reduction gear or, more generally, as a slip-on mechanism for whatever shaft happens to be present. <IMAGE>

Title: Cooking vessel made of non-metallic material
Inventor: RITTER ROLF ING GRAD
IPC: H05B6/12
Filed: 1987-06-26
Abstract: Known cooking vessels made of non-metallic material are not suitable for induction cookers. Instead, for induction cookers metal cooking vessels are used which have a heat-distributing base and in addition a magnetisable plate arranged on the heat-distributing base. As a result, it is however necessary to lessen the distortions owing to the different coefficients of thermal expansion between the magnetisable plate and the heat-distributing plate by providing at least two further intermediate layers. As a result, the previously known cooking pot is however expensive to manufacture and uneconomical in operation, since firstly the relatively large mass of the heat-distributing plate and of the cooking pot has to be heated up, before heat can be delivered to the product to be cooked. In order to render the construction more simple and less expensive, to increase the parboiling efficiency and to shorten the response time to a temperature regulation, there is proposed a cooking pot which consists of a combination of a vessel body made of a non-metallic material with an assigned body made of a material which can be heated by induction.

Abstract: The invention relates to a multi-component vehicle wheel with tyre, consisting of a wheel disc and a rim with a base which is arranged between the radially inwardly extending rim flanges and an essentially annular element with an oscillation-damping characteristic. In order to provide a vehicle with pneumatic tyres in which, in the event of a flat tyre, the roadway impacts which lead to damage to the rim and to parts of the running gear are suppressed or strongly damped, it is proposed that an oscillation element (12) which connects the rim (1) and the wheel disc (10) to one another in a frictionally engaging and/or postively engaging fashion be arranged between a rigidly constructed rim (1) and a wheel disc area which lies nearest to the rim base (2). <IMAGE>
Patent DE-3736826-A1 (DE)
Inventor: HUNDEGGER HANS
IPC: B27C1/04
Filed: 1987-10-30
Abstract: The planing machine possesses a total of four units which are arranged in pairs and consist in each case of a cutter block with a front shoe and a rear shoe. The units are movably mounted and are pressed by pressing forces against the corresponding working surface of the beam to be planed. In this way, it is possible to plane beams smooth, which for example even exhibit a slight curvature, since the units are able to follow the curvature owing to their flexible, movable mounting. There is no longer a need for expensive finishing operations.

Title: Vane pump for gases, vapours or similar pressure media
Inventor: FUERGUT ERICH
IPC: F01C21/08
Filed: 1987-12-01
Abstract: In the eccentric inner surface (8) of the support ring (5) fixed to the stator, and the outer surface, centered on the pump axis, of the rotor (15), a crescent-shaped working chamber (18) is formed which is subdivided by radially displaceable pump vanes (17) into four pump chambers (181-184) which are successively connected to inlet E and outlet A and thus deliver flow media from E to A. In order to improve the anti-friction characteristics of the pump vanes (17) there is provided, at least at the guide surfaces for the pump vanes (17) at the rotor (15), a copper-lead-tin alloy having a tin content of from 0.5% to 11.0%. The pump vanes have a copper-tin alloy having a tin content of from 5.5% to 9.0%. Thus advantageous anti-friction characteristics are maintained on a long-term basis even under unfavourable operating conditions, and thus run-up after standstill and centrifugal extension is facilitated. <IMAGE>

Title: Gable pack
Inventor: FAERBER JUERGEN
IPC: B65D5/06
Filed: 1987-12-05
Abstract: The invention relates to a cuboid gable pack for bulk goods, consisting of a multilayer plastic laminate on a carrier material, the top of which is closed by an upright seam whilst forming two triangular folding tabs lying double at the end sections of the upright seam, each folding tab being turned over outwards onto the respective side wall about a folding edge extending in a straight line and the package material having creases for the body and bottom or gable edges extending longitudinally, transversely or obliquely. Provision is made for the application to such a package of at least one auxiliary crease running outside the course of the body creases towards the vertical body creases in the gable region, the result of which is that, in the production of thick-walled packs and finally during the closure of the same in the filling machine, the durability of the upright seam closure in its original erection shape is attained, which means in the case of packs having relatively thick laminated materials that upright seam breakages are now avoided. <IMAGE>

Title: Fifthwheel coupling
Inventor: DREYER HANS
IPC: B62D53/08
Filed: 1987-12-06
Abstract: A fifthwheel coupling for an articulated road train has a fifthwheel pick-up plate (1) which receives the vertical load borne by the tractor, has an insertion slot (6) for a kingpin (7) mounted on a semitrailer and on which a thermoplastic anti-friction lining (2) is held in a positive manner and such that it can be exchanged by means of holding elements (3, 4) of the anti-friction lining (2), which elements are connected to the fifthwheel pick-up plate (1) and fit over the edge regions (11, 12) of the anti-friction lining (2). In order to prevent the usable thickness of the anti-friction lining from being adversely affected by the holding elements but nevertheless to allow the anti-friction lining to be easily exchanged, it is ensured that the upper side of the holding elements (3, 4) lies at most at the same level as the surface region of the fifthwheel pick-up plate (1), which receives the vertical load borne by the tractor. <IMAGE>
Patent DE-3741743-A1 (DE)
Title: Fuse switch
Inventor: BRUCHMANN KLAUS
IPC: H01H85/25
Filed: 1987-12-09
Abstract: The invention relates to a fuse switch (11) whose housing (12) has an insertion opening (13) for a fuse plunger which accommodates a fuse insert in a replaceable manner. When the fuse plunger is removed, a closure flap (29) for the insertion opening (13) is assigned to the insertion opening (13), as electric shock protection for the contacts in the housing. The closure flap (29) is held in the closed position by a fork spring (37) which can be operated, in the sense of being opened, by means of an unlocking device on the fuse plunger, so that the closure flap (29) can be moved into the open position (50), about a pivoting axis (30), against the prestressing of a closing spring (33). The closure flap (29) thus ensures that the fuse switch (11) is protected against being touched when the fuse plunger is removed, and furthermore protects the interior of the fuse switch against the ingress of dust or other substances which may have a detrimental effect on the operation of the switch. <IMAGE>

Patent DE-3807452-A1 (DE)
Title: Brake system
Inventor: VOLZ PETER DR
IPC: F04B49/24
Filed: 1988-03-08
Abstract: A brake system for motor vehicles with an antilock control device is demonstrated. A pump is provided which in the control mode delivers a reduced volume for positioning of a piston of the master cylinder. In the embodiment according to Fig. 2, reduction of the volumetric delivery is achieved in that the non-return valve (64, 65) is kept open. As a result the movements of the piston (56) are rendered ineffective with regard to the delivery of pressure medium. The non-return valve (64, 65) is kept open by a solenoid actuating unit (62). The actuating unit is controlled by the electronic control unit of the antilock device. In this way, it is ensured by simple means that at least one piston of the master cylinder and hence the brake pedal are arbitrarily positioned whilst in the control mode. <IMAGE>
