Patent DE-3224202-A1 (DE)
Title: Locking device
Inventor: ELLERT GUNNAR
IPC: B62D33/027
Filed: 1982-06-29
Abstract: The invention relates to a locking device for the automatic locking and release of a manoeuvrable flap, for example in a chip truck or a truck for the transport of solid material, the flap being liftable upwards and over the truck by means of at least one lifting arm mounted rotatably in the former, with any number of blocking hooks or blocking projections which are arranged along the side of the truck on which the manoeuvrable flap is provided, so that they engage round lower parts of the flap in the closed position of the latter. According to the invention, the lifting arm is mounted with one end (5b) rotatably in an intermediate member (106) by means of a journal (107) and the intermediate member is itself mounted rotatably in the flap (2) by means of a journal (108). The journals (107 and 108) are arranged eccentrically in relation to one another, with the result that the lifting movement of the lifting arm (5) generates a rotation of the intermediate member (106) outwards from the flap. A lowering movement of the lifting arm (5) generates an opposite rotation of the intermediate member. As a result of the eccentric mounting of the journals (107, 108), the lifting movement of the lifting arm (5) generates a straight upwardly directed movement (arrow B) of the flap, before it executes a movement upwards and outwards in the direction of movement of the lifting arm (5) (arrow D), and the flap moves straight downwards in the opposite direction during the last part of the lowering movement of the lifting arm (5) for the purpose of closing the flap. <IMAGE>

Patent DE-3226793-A1 (DE)
Title: Mould for manufacturing bellows
Inventor: BOSTEL KARL-HEINZ
IPC: B29C39/34
Filed: 1982-07-17
Abstract: In these moulds intended preferably for casting, a particular difficulty results if the protuberances of the folds are comparatively large and the moulding must be pulled out from the inner part of the mould. In order to be able to carry out this pulling out without danger, the outwardly cylindrical inner part has a plurality of rubber rings, which are pulled on with pre-tension, for demoulding these protuberances (undercuts), which rubber rings are disposed so as to be axially displaceable and are removed as the moulding is pulled off, but can then be pulled out of the moulding by deformation. The rings can be positively connected to the inner part of the mould.

Patent DE-3312058-A1 (DE)
Title: Pipe for floor heating
Inventor: HOEPPNER FRANK
IPC: F24D3/14
Filed: 1983-04-02
Abstract: The invention relates to a plastic pipe consisting of a basic pipe of, for example, polyethylene or polypropylene with a coating of a different polymer to reduce the oxygen permeability. In particular, in the case of a blend of PVDC and PU for the coating, with a coating thickness of 250  mu m, an oxygen barrier is already provided which is so effective that virtually 100% effectiveness is achieved. The coating is either applied to an existing pipe by extrusion or applied to the basic pipe by co-extrusion. The preferred blend ratio between PVDC and PU is in the range from 1:1 to 20:2. When this plastic pipe is used for floor heating, tight curves can be laid without detachment of the coating from the basic pipe occurring. The susceptibility to damage is also particularly low.

Patent DE-3320516-A1 (DE)
Title: Method and device for repairing leakage points in pipes
Inventor: EDER HANS PROF DR
IPC: B29C55/24
Filed: 1983-06-07
Abstract: Repairs of this type are carried out with a sleeve, the explosive charge of which acts directly on the sleeve wall and presses the latter onto the pipe inner wall to be repaired. In addition to the explosion welding, other regions of the sleeve are to be connected to the inner wall of the pipe by hard-soldering. To improve the repair, a method is proposed which produces less heat and only uses explosion welding. For this purpose, there is provided in a sleeve (4) an insert (7) which divides the interior of the sleeve into two chambers (9). The chambers are filled with a liquid and closed at the sleeve ends by discs (6). Each end of the insert (7) bears an explosive charge (8). Electronics for control and firing are arranged on the discs (6). After simultaneous firing of the explosive charge (8) on both sides there is a sharp increase in pressure in the liquid, which propagates therein, spreads out the sleeve (4) progressively from the explosion side and cold-welds it to the inner wall of the pipe. <IMAGE>

Title: Method for the operation of an internal combustion engine with at least one main combustion chamber and an assigned ignition chamber and internal combustion engine for implementing the method
Inventor: BABITZKA RUDOLF
IPC: H01T13/54
Filed: 1983-08-30
Abstract: The internal combustion engine (2) functioning according to the proposed method has a main combustion chamber (4) and an ignition chamber (7), which is supplied with operating mixture from the main combustion chamber solely by way of at least one injection duct (15, 16) for the production of at least one ignition flame, by means of which the operating mixture in the main combustion chamber is fired. The cross section of at least one of the ignition flames can be varied by means of a rotary slide valve (17). For this purpose an adjusting element (19), which is exposed to combustion gases, acts on the rotary slide valve (17). From idling up to high loads of the internal combustion engine the temperature of the adjusting element (19) increases. As a result the total ignition flame cross section is increased so that ignition flames beyond this enlarged total ignition flame cross section are accelerated less than when idling. Consequently the combustion pressure in the main combustion chamber (4) of the internal combustion engine (2) increases both when idling and at low and high load at an advantageous rate. <IMAGE>

Title: Arrangement for adjusting the axial play or the axial preloading force for the bearings of a rotor shaft
Inventor: SCHMIDT HELMUT
IPC: H02K5/173
Filed: 1983-12-07
Abstract: To allow simple adjustment of the axial play of a rotor shaft mounted in plain bearings or the axial preloading force of a low-power motor rotor shaft (RW) mounted in a bearing bore (LB) in a ball bearing (KL) and preloaded axially via a resilient disc (FS), it is proposed that the axially inner front face of an adjusting disc (ES), which disc is rotatable through the bearing bore (LB) from a point axially to the outside, be movable up against the rotor shaft to give a defined axial play or defined preloading force by virtue of its axially outer front face - provided over its circumference with rows of supporting steps (ST1-ST4 and ST5-ST8 respectively) - being supported, in each case by means of a corresponding supporting step of the said row, against a stud (N1 and N2 respectively) projecting into the bearing bore and serving as an abutment. In this position, further rotation of the adjusting disc (ES) is prevented by the striking of a corresponding stop step (STI-STIV and STV-STVIII) arranged between two supporting steps which projects axially by the maximum installation height of the resilient disc (FS) beyond the next successive supporting step and by the minimum installation height of the said disc beyond the preceding supporting step. The invention is particularly suitable for use with low-power motors of all kinds with axial-play adjustment or preloading of the bearings.
