Patent DE-3109690-A1 (DE)
Title: Rotor, especially for a rotary-wing aircraft
Inventor: STEPHAN MICHAEL DIPL ING
IPC: B64C27/35
Filed: 1981-03-13
Abstract: The invention relates to a rotor having rotor blades which move in terms of rotation angle on the rotor head in blade holders (rotor arms) which extend radially outwards. In this case, the individual blade roots are intended to be held in the associated blade holder via a support which can be stressed in compression in the blade longitudinal direction and at the same time permits blade incidence-angle movements, and furthermore, during the blade pivoting movements, act in a shear-deforming manner on an elastomeric connection (which is capable of damping and is produced for blade retention) by means of an intermediate element which extends beyond the said support; the intermediate element is at the same time supported via a bearing journal (which is coaxial with respect to the blade angle axis) on the root of the blade holder in a radial elastomeric bearing. In the case of such a rotor, in order to keep the elastomeric connection which is capable of damping largely free of shear stress resulting from the blade pivoting moments, it is produced between the blade holder (limb 2.1) and a coaxial projection (41.3) of the bearing journal (41.2). In addition, this journal projection (41.3) is connected to the elastomeric connection (elastomeric layers 50) in a connection (radial bearing 51) which is stiff in compression in the blade pivoting direction but allows its rotational angle movements. <IMAGE>

For this purpose, the outlet opening of a tube which delivers the storage medium at the bottom into the PCM is covered by a member which extends as far as above the surface of the storage medium. The member consists of a material which although pervious to the heat exchange medium is not so for the storage medium in the liquid phase. <IMAGE>
Patent DE-3117144-A1 (DE)
Title: Starter device for a multi-cylinder spark-ignition engine
Inventor: BENDER ULRICH
IPC: F02N99/00
Filed: 1981-04-30
Abstract: Multi-cylinder spark-ignition engines the combustion chambers of which are supplied with fuel by petrol injection have starter devices. Starter devices of this type are to be designed so that they have a low energy requirement, are of low weight, permit the use of accumulators with a low ampere-hour number and generate no unwanted starter noise. To this end it is proposed that a detector device should signal the respective piston state of the engine to a microprocessor which, when starting, causes a quantity of fuel necessary for combustion to be injected into and ignited in that cylinder of which the piston is in the working position, and thereafter fuel to be injected into that cylinder of which the piston will perform the next working stroke, followed by ignition as soon as the piston in question has reached the working position.
Patent DE-3117644-A1 (DE)
Title: Device for recovering the heat dissipated by a furnace or the like
Inventor: NESS EDUARD
IPC: F24H9/02
Filed: 1981-05-05
Abstract: Boilers, furnaces or the like, which are not or poorly insulated, dissipate a substantial heat quantity by convection to the ambient air. If the furnace is located in a room, the latter can certainly be directly heated thereby, but as a rule the heat yield is so great that it is mostly impossible to make any use of the overwhelming part of it. The latter also applies when an industrial furnace is set up, for example, in the open or in a room that is not completely closed. In order to recover at least a part of said heat dissipated by the furnace or the like, and in some way or other to be able to use it for purposeful heating or warming of a room or medium, the furnace (1) is surrounded by a casing (2) which bears on its inside a ductwork (9) through which a heat carrier flows with the aid of which heat can be extracted from the region of the oven or the like. Heat can be extracted from the heat carrier in a heat exchanger, a heater or the like and be used for the said heating or warming purposes. The casing is preferably constructed in two parts, so that its two parts can be folded down sideways in the sense of the arrows (5 or 6). This is performed automatically when there is a failure of the flow with the aid of which a pump pumps the heat carrier through the ductwork (9). <IMAGE>

Title: Process for the production of knitting tools
Inventor: BLIESKE THOMAS
IPC: D04B35/02
Filed: 1981-10-16
Abstract: The invention relates to a process for the production of knitting tools, especially of compound or bearded needles. The aim of the invention is the production of knitting tools in large quantity and of uniformly high quality. The object of the invention is to provide a process for the production of knitting tools, in which a high quality can be obtained by an exactly defined position of the various working faces in relation to one another. This object is achieved in that one end of a blank in the form of a cylindrical pin is reduced in cross-section to a rotationally symmetrical tip corresponding to the diametral profile of the needle head to be bent, thereafter the shank of the blank is simultaneously equipped with a technological reference base and grooved, and subsequently plane side faces are cut in the shank in the region of the groove and the tip of reduced cross-section is bent and curved to form the needle head. <IMAGE>

Title: Lattice mat and method for its manufacture from supplied steel wires
Inventor: HAEBERLE LUDWIG
IPC: E04C5/04
Filed: 1981-11-20
Abstract: Novel embodiment of lattice mats - in particular for floating screeds - which consist of steel wires and are intended to contain a hot-water floor heating system. Individual steel wires have zones which protrude on one side by about 1 cm from the plane of the lattice mat and which serve as supports when the lattice mat is laid onto the respective base and which ensure, upon application of the concrete, that the lattice mat is kept at a predetermined distance from the underside of the concrete slab to be produced for the floating screed. Before introducing the concrete, it is possible for the lattice mat to be walked on, for example for the purpose of mounting the hot-water floor heating system, since the steel wires are elastically deformable in the region between the supports. The bent zones are produced by means of stamping tools which are arranged in front of or between the welding tools provided for welding the individual steel wires.

Title: Electronic-mechanical safety insert of a fuze of an explosive body
Inventor: KNUEFELMANN MANFRED
IPC: F42C15/40
Filed: 1982-01-02
Abstract: An electronic-mechanical safety insert for a fuze of an explosive body, having a release device, which can be triggered by a time controller, for a detonator. The technical problem of the invention is to achieve unconditional safety of a safety time before arming the fuze, and to make it possible to adjust the arming duration after the elapse of which the fuze is disarmed. A pulse oscillator acts on a counting circuit which defines a safety time (t1). The output pulse from the said counting circuit switches a switch (73) which closes a circuit for an electric motor (53) to drive a rotating disc (56) which is used as a release device. The rotating disc (56) carries a detonator (57) and is rotated until the bolt of the detonator (57) is aligned with an initial fuze. On completion of the rotation of the rotating disc (56), a switch (C1) is operated which acts on the pre-setting inputs (A, B, C, D) of a programmable counter in order to define an arming duration (t2). The output signal from the programmable counter triggers a circuit for cancelling the arming. <IMAGE>

Patent DE-3215791-A1 (DE)
Title: Process for the production of optical glass fibres having a gradient index profile
Inventor: KIMMICH KLAUS DIPL PHYS
IPC: C03B37/014
Filed: 1982-04-28
Abstract: Processes for the production of gradient fibres are the tube interior coating process and the process of external coating of a cylindrical blank, in which several layers of different refractive index are applied one after the other. According to the invention, layers of decreasing thickness or, in the case of external coating, of increasing thickness are applied one after the other in such a way that layers of approximately identical thickness are formed therefrom in the fibre preform obtained by collapsing and finally in the fibres. The desired parabolic refractive index profile can thus be approximated, in particular in the critical region in the core centre, with increased accuracy. The process therefore promises an improvement in fibre dispersion and presumably a reduction in mode noise. <IMAGE>

Title: Stereo imaging method for producing, recording and transmitting individual images which can be perceived in colours and plastically
IPC: G03B35/00
Filed: 1982-05-21
Abstract: Both beams which are intended to reach the left eye and beams which are intended for the right eye pass into a novel stereo attachment (stereoscopic attachment), as in the case of the previous stereo attachments, onto deflection elements at the base separation. However the two groups of beams now go through two mutually complementary-coloured filters, so that, for example, the left stereo image still contains only the spectral colours of red to orange and the right stereo image still contains only the remaining spectral colours of yellow to violet. These two stereo images are combined by means of a beam splitter to form a single image which is photographed using a normal camera. Only one transmission path and one video tape recorder are required for transmission and recording. Reproduction is carried out on a single colour television screen, with the aid of a colour cine film, in a colour slide or a coloured paper image. Stereo glasses with suitable lenses, of complementary colour to one another, are required for viewing. The stereo imaging method is partially compatible since, for a predetermined object plane, a colour image is produced which is seen in the correct colours even without stereo glasses.
