Title: Linear drive
Inventor: HORN HANS
IPC: F16H19/06
Filed: 1983-03-22
Abstract: The invention relates to a linear drive with a pneumatic or hydraulic lifting cylinder, the piston rod (10) of which is fixed, the movable and longitudinally guided cylinder (6) being the load-bearing and driving part of a lifting transmission gearing which converts the relative motion between the cylinder (6) and its longitudinal guide and transmits it to the linearly movable driver (1). It is advantageous to guide the driver (1) on the outside of a slotted tube (3), the driver (1) projecting by its lug (2) into the slot of the tube (3) and being rigidly connected to the internal lifting transmission gearing. The tube (3) surrounding the cylinder (6) serves as a longitudinal guide for the cylinder (6). The lifting transmission gearing comprises, for example, two pulleys (5) secured on the cylinder (6) and the circulating rope (8) which is firmly connected, on the one hand, to the driver (1) and, on the other hand, is held on the tube (3) at an anchorage (9). In a preferred embodiment, the cylinder (6) has a continuous piston rod secured at both ends. In this solution, it is the piston rod which provides longitudinal guidance for the cylinder (6). <IMAGE>

Title: Monolithically integrated rectifier bridge circuit
Inventor: STOERRLE HANSMARTIN DIPL ING
IPC: H02M7/219
Filed: 1984-01-13
Abstract: A monolithically integrated rectifier bridge circuit, in which it is ensured that, when the supply AC voltage changes its mathematical sign, none of the substrate diodes which are formed between the circuit elements acting as a rectifier and the semiconductor body becomes conductive. This is achieved in that the four rectifying elements of the bridge are formed by bipolar transistors connected as rectifiers, NPN-transistors connected as rectifiers being located in each case between an AC voltage input and the negative terminal of the bridge, and the negative terminal of the bridge being connected to the substrate of the integrated circuit. It is also possible to design the four rectifying elements of the bridge by means of field-effect transistors, which are connected as rectifiers and are constructed using CMOS technology, P-channel transistors connected as rectifiers then being located in each case between one AC voltage input and the negative terminal of the bridge, N-channel transistors connected as rectifiers being located in each case between one AC voltage input and the positive terminal of the bridge, and the positive terminal of the bridge being connected to the substrate of the integrated circuit. <IMAGE>

Patent DE-3407789-A1 (DE)
Title: Screw extruder
Inventor: SCHIPPERS HEINZ DIPL ING DR
IPC: B29C48/67
Filed: 1984-03-02
Abstract: The invention relates to a screw extruder having a melting zone and an adjoining pressure-compensating and output zone. The object of the invention is the reliable elimination of the pressure fluctuations occurring in the melting zone. This is achieved in that, directly downstream of the melting zone in the extruder wall or externally on the extruder wall, there is provided a pressure-compensating buffer which, by temporarily receiving a part-volume of the melt, dependent on the current local pressure, or releasing the same, ensures the compensation of pressure fluctuations. In any event, a volume which changes by the effect of pressure or by changing the local pressure proportionally to the pressure change is provided on the extruder barrel. As it was possible to find out, diaphragms which are pre-tensioned by gas pressure or spring force and can be mounted in bypass chambers or across enlargements in diameter are especially suitable for this.

Title: Vaporising burner for liquid fuel and method for its operation
Inventor: PETERSEN JOERGEN HARTVIG
IPC: F23D11/44
Filed: 1984-05-23
Abstract: A vaporising burner for liquid fuel has a tubular vaporisation chamber (2) which has a vaporisation zone (A) and a glow zone (B). A resistance heating device is formed by the vaporisation chamber wall, which comprises at least one pipe section (5, 6, 7) and is electrically conductive. It has two connection electrodes (15, 16) at the ends and a third connection electrode (17) between vaporisation zone (A) and glow zone (B). The vaporisation chamber wall is thereby divided into two resistance sections which can be actuated independently of one another. It is thereby possible to dimension the heat outputs to be fed to the resistance sections during starting in such a way that the glow zone (B) assumes a wall temperature in excess of 700 DEG C and the vaporisation zone (A) a wall temperature of less than 350 DEG C. In addition, the wall temperature of the glow zone can be reduced to less than 400 DEG C after ignition. This results in reliable ignition, thorough vaporisation and stable operation of the flame. <IMAGE>

Title: High-temperature reactor with a support structure for the side reflector
Inventor: ELTER CLAUS DIPL ING DR
IPC: G21C1/07
Filed: 1984-05-24
Abstract: The invention relates to a high-temperature reactor installed in a pressure vessel and having preferably spherical fuel elements, the core of which reactor is surrounded laterally by a cylindrical side reflector and a thermal side shield. In the annular space between the two said components, an elastic support structure for the side reflector is provided which has roller bearings mounted on the side reflector and spring elements located in housings. The object of the invention is to configure the thermal side shield in an extendable fashion. In order to achieve this, the side shield consists of flat, rectangular metal plates which are loosely stacked one upon the other and are guided in vertical contact rails with an I-shaped profile which are arranged around the side reflector. One limb of the contact rails is connected in each case to a number of roller bearings which are arranged one below the other in a row. Mounted on the other limb of each contact rail is the same number of housings for the spring elements, specifically at the same level as the roller bearings in each case. The ends of the housings averted from the core are connected in each case by means of a multipart clamping ring to connecting tubes which are welded to the liner lining the pressure vessel cavity. The forces of the core are thus introduced via the support structure and the liner directly into the pressure vessel.

Title: Two-shell folding wall which can be pulled out flat
Inventor: KINDLER ADOLF DIPL ING
IPC: E06B3/94
Filed: 1984-07-16
Abstract: Normally, a folding wall consisting of individual elements is suspended in such a manner that, in particular, each upright has a roller which runs in the ceiling rail. In the present embodiment, however, the rollers are fastened to the elements. In order, in the folding movement of such a folding wall, to avoid all the elements being folded simultaneously, which requires a comparatively great force, it is envisaged here that essentially every second element is provided with a roller. Attached as a characterising drawing is diagram 2 of the application, from which it can be seen that, during the folding process, for example only two elements are folded, while the remaining elements are still for example situated in the extended position. <IMAGE>
