Patent DE-3122960-A1 (DE)
Title: Fluid friction clutch with a pumping device which forms a lubricating wedge
Inventor: REIS OSWALD DIPL ING
IPC: F16D35/02
Filed: 1981-06-10
Abstract: The pumping device for emptying the working space of a fluid friction clutch consists of a region between the input and output parts of the friction clutch in which the lubricating wedge is formed. This results in a build-up in the force of the pressure in the shearing fluid in this region, approximately perpendicularly to its direction of flow, a phenomenon familiar from hydrodynamic lubrication theory, and arranged in the region of the maximum of these pressure forces is an opening for carrying the shearing fluid out of the working space into a reservoir space.

Title: Coupling for rail-bound vehicles in underground mining operations
Inventor: MEISSEL KLAUS PETER DR ING
IPC: B61G3/00
Filed: 1981-07-08
Abstract: The coupling illustrated in the figures is intended for rail-bound vehicles, in particular passenger vehicles, in underground mining operations. The basic design includes firstly a coupling housing, a coupling element which protrudes at the end over the coupling housing, a coupling element receptacle and a lock element. The complementary coupling element of the coupling of a vehicle which is to be coupled on can be inserted into the coupling element receptacle. It can be secured there with the aid of the locking element. The coupling housing can be displaced in a buffered fashion with the aid of a bolt which is essentially horizontal in the normal position so as to be capable of being swivelled about a vertical axis by means of a ball-and-socket joint. For this purpose, in the exemplary embodiment it is provided with a sleeve on the horizontal bolt and the buffer springs are rubber-coated metal elements. The normal position is fixed by means of stabilising elements which consist of stabilising levers and a stabilising spring. The coupling element is constructed as a clip which is rigidly connected to the coupling housing. The said clip has a coupling ring with a hole axis which is essentially vertical in the normal position. The locking element is designed as a locking bolt which is essentially vertical and loaded by a locking bolt spring in the normal position. This locking bolt is displaceably mounted in the coupling housing above the coupling element receptacle in its axial direction and can be inserted into a locking bolt bore underneath the coupling element receptacle. In the coupling element receptacle, a blocking element is arranged so as to be capable of swivelling about a vertical axis counter to a restoring spring. The said blocking element blocks the locking bolt bore in the position of rest and as a result secures the locking bolt above the locking bolt bore. The blocking element can be swivelled back from the complementary coupling element of the coupling of a vehicle which is to be coupled on thus releasing the locking bolt so that the locking bolt drops into the coupling ring of the complementary coupling element and subsequently into its locking bolt bore. <IMAGE>

Title: Push-type luggage trolley which can be nested with corresponding trolleys
IPC: B62B5/04
Filed: 1981-07-16
Abstract: In order to obtain a sufficient degree of comfort for the user of push-type luggage trolleys which can be nested with corresponding trolleys and whose overall centre of gravity, with the overall length of the trolley being kept as small as possible, is to be arranged as low as possible in such a manner that the trolley can still be reliably braked even on relatively steep slopes, it is proposed that the support rods forming the loading area be rigidly connected to the frame which surrounds the loading area and is arranged in a plane running at the level of the castor axes, and in the region of the longitudinal centre of this frame be connected to frame parts which deviate from the circular shape and allow the castor of the trolley to be pushed in to pivot freely. Furthermore, each castor is suspended by means of a rotary ring limited in its pivoting freedom over a pivoting radius of 180 DEG , and the limb which is positioned towards the centre of the trolley is extended downwards beyond the castor axis. <IMAGE>

Title: Process for producing a closing lug for the fittings of windows, doors or the like
Inventor: RIEDEL WERNER
IPC: B29C45/14
Filed: 1982-02-02
Abstract: In a process for producing a closing lug for the fittings of windows, doors or the like, first a pin having a rivet shank of a supporting shoulder at one end and an injection shank at the other end is produced by turning. Then the pin is introduced into a casting mould where a closure head arranged eccentrically to the pin axis and consisting of castable material such as plasticised plastic is injected around the injection shank. In order always to obtain a defined torque for the adjustment of the eccentric closure head, it is proposed to mould-on a disc of castable material, in particular of plastic, covering the supporting shoulder at the transition point to the rivet shank and in the process to arrive at a disc thickness compensating for the particular tolerance length differences of the rivet shank.

Abstract: The car ladder for a dog consists of a board (or plurality of boards) with transverse bars. On it, the dog can very satisfactorily climb into and out of the luggage compartment despite the rear apron of the car. Because the dog no longer has to be carried into or lifted out of the luggage compartment, the danger of soiling of clothing is eliminated. Also, the dog no longer needs to be accommodated in the passenger compartment, which can thus remain clean. Variable size permits use with a wide variety of makes of car. A collapsible design permits space-saving stowage of the ladder in the luggage compartment.

Abstract: The valve shaft (17) of the ball plug (14) projects sealingly through the sleeve extension (26) of the valve housing (13) of an underfloor-arranged branch valve (12) for water pipe connections or the like and forms a square (24). To couple this square to a pole wrench passed down from above the floor, use is made of a coupling bushing (27) which is passed by way of its lower hollow over the predominantly cylindrical outer face (35) of the sleeve extension (26) with a snug fit, engages round the square (24) by way of an inner square face (34), is axially supported on the valve housing by way of its lower end (36) and is held against this stop by means of a nut (37) which is screwed onto the valve shaft (17) and presses against the inner collar (33) of the coupling bushing (27). To the outer square (29) can be attached the associated wrench face of the pole wrench. The coupling bushing (27) must be held on the valve housing (13) as far as possible free from radial play and secure against tilting, so that all forces of the pole wrench are directly transmitted to the valve housing. Radial play can optionally remain between the square faces (24) and (34). Instead of the outer square (29), an inner wrench face can be provided to permit firm connection of a pole wrench in the case of tapping fittings. <IMAGE>
