Patent DE-3145153-A1 (DE)
Title: Pultruded anchoring bar of curable synthetic resin
IPC: B29C59/02
Filed: 1981-11-13
Abstract: The pultruded anchoring bar of curable synthetic resin, embedded in which are reinforcing fibres, in particular glass fibres, extending over the length of the bar, has in particular, to increase its tensile and torsional strength, at least one anchor channel on its outer circumference, which channel extends over the length of the bar and penetrates merely into the synthetic resin compound of the bar, the reinforcing fibres being inwardly deflected in the region of the anchor channel and bypassing the anchor channel without intersecting it. To produce such an anchoring bar, a continuous strand of reinforcing fibres is drawn essentially continuously through a die approach and the strand, completely impregnated with synthetic resin, is shaped in the die approach to form a bar corresponding in its cross-section to that of the die approach and is cured. At the same time, a wire of metal or such like material, also continuous, is led up to the strand of reinforcing fibres before the latter runs into the die approach and is passed together with the strand through the die approach. Subsequently, the wire is removed, leaving behind in the finished bar an anchor channel corresponding to the cross-section of the said wire.

Title: Container for a preferably circular support disc for photographic negative material
IPC: G03B17/26
Filed: 1982-02-12
Abstract: The invention relates to a container for a preferably circular support disc for photographic negative material which has at least one retaining projection at the centre. On this support disc, the photographs are recorded in the form of rectangular negatives. The individual negative is extremely small in respect of its lateral dimensions. Since, however, enlargements are to be made from these negatives, the film disc must be particularly well protected against damage, since otherwise the enlargements become useless. The object of the invention is to provide a container in which the support disc can be stored or transported safe from damage, and which permits observation of the negatives without its being necessary to remove the support disc from the container for this purpose. This object has been achieved, according to the invention, in that the container consists of half-shells which can be assembled together and in which at least one positive-locking element, corresponding to the retaining projection of the support disc, is arranged, and in that it has at least one negative observation window.
Patent DE-3205814-A1 (DE)
Title: Two-stroke diesel engine with opposing free pistons
Inventor: WAGNER ALBERT
IPC: F02B3/06
Filed: 1982-02-18
Abstract: In the case of a two-stroke diesel engine with opposing free pistons (2) and hydraulic pump (3), the reciprocating movement of the free pistons through the hydraulic oil or water delivered by the hydraulic pump is translated into rotational movement by a hydraulic motor or a free jet turbine. On the return of the free pistons acceleration occurs largely due to the air compressed in the buffer chambers of the free pistons. Each cylinder has an injection pump (10). Tangential injection into the cylinder results in good mixing and complete combustion in the air charge rotating in the same direction. The injection pump connected to the compression chamber by a short duct is also connected to the starter injection pump and to the starter pneumatic valve. In the case of automatic control of the injection quantity by the delivery pressure of the hydraulic pump, the cylinder is actuated by an actuating rod (18), which acts on the fuel pumps and on the starter pneumatic valves. <IMAGE>

Patent DE-3223961-A1 (DE)
Title: Top-pan balance
Inventor: SAUTER MARTIN ING GRAD
IPC: G01G21/24
Filed: 1982-06-26
Abstract: On top-pan balances with electrical measurement processing by electrical measurement transducers, for example in the form of bending beams equipped with strain gauges, it is to be possible to measure even relatively small loads with minimum measuring paths and high resolution. For this, the measuring element incorporated in the parallel guide is equipped as a horizontally rigid bending beam with two flexurally elastic joints, so that the deformations remain restricted to a short distance. The strain gauges to be attached here therefore already undergo relatively high deformations even under small loads.

Title: Dérailleur gear-shift with separate locking device
Inventor: EISEND EWALD
IPC: B62M25/02
Filed: 1983-01-13
Abstract: The invention relates to the arrangement of a locking device for a dérailleur gear-shift in the transmission path between switch and chain-guiding and -tensioning device. This arrangement is to be capable of being subsequently fitted in particular without changing existing simple dérailleur gear-shifts. The locking device is attached preferably in the vicinity of the dérailleur gear-shift to the frame of the bicycle and two variants are proposed. In one embodiment a simple switch with friction brake is provided which displaces a locking ball with respect to a connecting link, specifically with the intermediate connection of a gear-shift spring for the selection of the speed in one direction and with the intermediate connection of a gear-shift spring for the selection of the speed in the opposite direction. In another embodiment the switch and locking device are designed in such a way that a switch-over path can be realised in at least one gear-shift direction. As a result, the gear-shift process is made substantially easier at least when changing from a small chain wheel to a large one. This embodiment can be developed further by also installing a switch-over device in the opposite gear-shift direction.

Title: Mould-closing unit of a diecasting or injection-moulding machine
Inventor: KLENK WALTER
IPC: B22D17/26
Filed: 1983-07-13
Abstract: The unit consists of horizontal carrier beams for the movable mould platen, supported at one end on the stationary mould support and at the other end on a mounting platen of the machine foot, one or more height-adjustable support members between the machine foot and the movable mould platen and a measuring device for the indication of the deviation from the plane parallel position of the movable mould platen relative to the stationary mould platen. In order to prevent the tilting of the movable mould platen 7 after insertion of the movable mould half 8, one or more support members 13 are interposed between the movable mould half 8 and the machine foot. A further tilting can arise due to the different heating of the mould half 8 and of the mould platen 7 during the casting operation. In order to prevent this, it is proposed according to the invention that the measuring device is a fixed component of the machine, and that hydraulic piston-cylinder units or motor-drivable positioning spindles are arranged as support members, and the displacement drives of the support members (pressure medium source, stepping motor) are automatically controllable by the measuring device. <IMAGE>

Title: Circuit arrangement for switching on control devices of telephone sets
Inventor: VOGT WALTER
IPC: H04M1/60
Filed: 1983-08-16
Abstract: With the circuit arrangement for switching on control devices of telephone sets it is ensured that the current required from a battery at the moment of switching on is taken only very briefly. The circuit arrangement, predominantly comprising electronic switching means, ensures that the battery is switched off immediately the voltage generated from the loop current is available. With the then higher operating voltage, the transistor which previously had switched on the battery voltage is turned off. For forming the loop when the handset is hung up, a relay is used, the contact of which bridges the cradle switch contact. This relay is switched off immediately the loop circuit is taken over by the cradle switch contact.
