Title: Composite window frame section - consists of two hollow sections joined together and hollow space filled with plastic foam
Inventor: LADEMANN HORST
IPC: E06B3/263
Filed: 1980-12-01
Abstract: The frame elements of the window or door are built up from metal part sections (2,3). They are put together in such a way that along the entire length a gap is formed which is filled with plastics foam (4) which keeps together the metal part sections (2,3) and the frame elements. It forms a heat barrier between the two part sections. Each part section is shaped to form a hollow flange (2,3) respectively and the free edges (2,3) are bent in an angle to provide an anchoring element in the foam material. The two part elements (2,3) are placed together in such a way that their edges (2,3) do not touch, preventing formation of a heat bridge. On the outer surface of the composite frame a recess (6) is formed serving as an anchoring device for a frame sealing strip. The flange (2) pointing inwards the window surface serves as an abutment for the pane (7) and the opposite side is fitted with a cover strip (8) holding in place the window pane assembly (7).

Patent DE-3110363-A1 (DE)
Title: Cistern outlet valve
Inventor: STRANGFELD REINER DIPL ING
IPC: E03D1/30
Filed: 1981-03-17
Abstract: The cistern outlet valve has a float plunger (2) which actuates the main valve (3, 4) and can move up and down in a bell (1) which can be pushed downwards against a restoring force to open an auxiliary valve (6, 111). The float plunger (2) defines on its upper side with the bell (1) a cylinder space (13) which can be emptied via the auxiliary valve and filled up again by a restricted inflow. In order that the float plunger (2) lifts off reliably from its seat to open the main valve and in order that it then does not lift off unintentionally in the filling phase of the cistern, there is provided between the lower region of the cylinder space (13) and the cistern space an inlet which opens only with an unactuated outlet valve and, in the filling phase, with an unactuated bell, bridges the restriction in the flow to the cylinder space (13). <IMAGE>
Patent DE-3119788-A1 (DE)
Title: Method of improving the performance number of a refrigerating-machine or a heat-pump cyclic process and apparatus for implementing the method
Inventor: MOEHLENBECK KLAUS-JUERGEN ING
IPC: F24D11/02
Filed: 1981-05-19
Abstract: The method serves for improving the performance number in a refrigerating-machine or heat-pump cyclic process. It is not achieved by the media involved being cooled or warmed by heat exchange to the respective end temperature in a continuous flowthrough, but the reaching of the end temperature takes place discontinuously, and in particular, at the beginning, a tank is filled with the medium which is to be heated for example in a condenser, the content being circulated repeatedly via the condenser so that it is heated and, when the end temperature is reached, exchanged for cold medium. The greatest advantage of this method results when the overall temperature change is great.

Patent DE-3133616-A1 (DE)
Title: Method for producing ice figures
Inventor: HOBELSBERGER JUN JOSEF
IPC: F25C1/04
Filed: 1981-08-25
Abstract: A method for producing ice figures for decorative purposes is shown, in which water is poured into a casting mould (1) which depicts the ice figure as a negative shape and has substantially rigid walls (12a, 41), the filled casting mould (1) is cooled to below the freezing point of the water and the ice figure then produced is removed from the casting mould (1). Previously, ice figures were not cast, but hewn out of blocks of ice using a hammer and chisel. Previously a production method by casting appeared to be impossible due to the knowledge of the great expansion in volume of the ice relative to the quantity of the freezing water and due to the requirement for a precise, finely structured and greatly diverse shape of an ice figure, which can only be achieved by a rigid mould. It has surprisingly been shown that ice has such a high flow capacity that even relatively complicated casting moulds (1) with sturdy walls are filled with ice without suffering damage insofar as the ice is only given a yielding possibility for expansion inside or outside the casting mould (1). Furthermore, a casting mould (1) which is suitable for carrying out the method is shown, which casting mould consists of a case (2, 27) into which shaped pieces (5 to 8; 31 to 36) are introduced, which enclose a hollow space (12, 40) which depicts the negative shape of the desired ice figure. Various shaped pieces (5 to 8; 31 to 36) are to be designed and adapted to one another in such a way that many shapes of ice figures can be created by combining a limited number of shaped pieces. <IMAGE>
Patent DE-3133858-A1 (DE)
Title: Device for severing in particular a stoneware pipe
Inventor: HOCK KARL
IPC: B28D1/22
Filed: 1981-08-27
Abstract: The device for severing a pipe made of stoneware or the like consists essentially of an open severing ring (1) and a clamping device, with the aid of which the inner contour of the severing ring can be made smaller, which leads to radial pressing of the pipe at the severing point. In this case, the local pressure is so great that the pipe breaks apart suddenly when a material-dependent maximum value is reached. The great local pressure is achieved in particular by using a pressure rib (5) which is approximately wedge-shaped in cross-section and which is preferably divided into individual, toothlike pressure members (7), in association with a transverse clamping device. The latter consists essentially of the two clamping members (8 and 9) as well as a clamping member (10) designed preferably as a flat wedge. The clamping members are provided with push-through openings (13 and 14) which at the beginning of clamping lie partially congruently so that a push-through duct (16) is created for the narrow wedge end region (17). By driving the wedge in, the breadth (18) of this push-through duct (16) is enlarged and at the same time the clear width of the severing ring (1) is made smaller, which leads to severing. <IMAGE>

Title: Blade-carrying rail for longitudinally cutting moving weblike two-dimensional structures, especially webs of plastic film
Inventor: BRAUN SIEGFRIED
IPC: B26D5/02
Filed: 1981-09-23
Abstract: For a system for producing flat fibres or ribbons (4), especially from webs of plastic film, there is proposed a blade-carrying rail which is intended for longitudinally cutting the fed two-dimensional structure (3) and makes it possible to change cutters without interrupting cutting and therefore to achieve a much higher level of productivity than systems with other known blade-carrying rails (1). According to the invention, preferably six blades (9) are inserted into rectangular grooves (8) which are distributed around the circumference, are situated in the same normal plane and have been cut into the blade-carrying rail (5). The cutting planes are separated by means of spacing rings (11) to the desired ribbon width and the entire blade-carrying rail is axially braced by means of a union nut (13). By means of a ratchet wheel (15), the blade-carrying rail (1) can be turned onwards as the engaged blades (9) are exchanged. In this process, the unused row of cutting edges (10) is rotated, without setting, by means of a special arrangement of the blades (9), into the cutting paths of the row of cutters moved out of cutting engagement. <IMAGE>

Title: Method for producing and fitting the pins of a supporting plate which can be plugged vertically onto a printed-circuit board by means of a plurality of rows of these pins
Inventor: PRUSSAS HERBERT DIPL ING
IPC: H01R12/52
Filed: 1981-09-25
Abstract: A method for producing and fitting the pins (Pa, Pi) of a supporting plate for VLSI modules, which can be plugged vertically onto a printed-circuit board by means of a plurality of rows of these pins. The connecting spots for the pins (Pi, Pa) are fitted on the supporting plate together with the lines. At least two rows of pins (Pi, Pa) are produced from conductive thick-film material in one piece above a common rail (Sch) connected in the form of a comb to the left and right of the rail (Sch). The pins, which are then bent into their final shape, are soldered to the connecting spots. The rail (Sch) is finally removed, preferably by cutting off or by pulling off by means of an auxiliary tool. <IMAGE>

Title: Mechanical torque wrench (torque measurement outside the centre of application)
Inventor: MAYER EBERHARD DIPL ING DR
IPC: B25B23/143
Filed: 1981-10-03
Abstract: To obtain a reading which is independent of the point of application of force in a mechanical torque wrench, it is proposed to provide such a wrench with a compensation measuring point which eliminates measuring errors attributable to displacements of the point of application of force in that the measured value of the initial measuring point is reduced by an amount corresponding to the two measuring points in proportion to the lever arm lengths relating to the point of transmission of the measured value to a measuring member. <IMAGE>
Patent DE-3143193-A1 (DE)
Title: Controllable external-shaft rotary piston compressor
Inventor: WERNER-LARSEN OLAF
IPC: F04C28/26
Filed: 1981-10-30
Abstract: The invention relates to a screw compressor in which a slide valve element and a movable sliding stop element are provided in an axially parallel recess, open to at least one of the rotor bores, of the housing peripheral wall and are axially actuatable independently of one another. By means of the sliding stop element a return flow slot to the inlet aperture can be opened, which results in the machine running only at partial load. Different partial load capacities can be obtained by different combinations of slot size and slide valve position, but only one of these combinations provides the optimum efficiency. In order to permit operation of the compressor with high efficiency under at least two different partial load conditions, according to the invention at least one further valve element (7) is arranged inside the recess (3) between the slide valve element (5) and the sliding stop element (6), which valve element (7) can be displaced by means of its own actuating device (12) both separately between the first and the second element (5 and 6) and bearing on the first or second element to form an extension thereof. <IMAGE>

Title: Transportation device
Inventor: MUELLER GERVIN J DIPL ING
IPC: E04G21/14
Filed: 1982-01-28
Abstract: Concreted into the structural body of concrete room units are transportation anchors, by which the room unit can be lifted during transportation from the factory to the site or during subsequent moves. If the roof panel of the roof unit is mounted separately, the transportation anchors must be concreted into the side walls of the room unit. It is proposed to concrete the anchor sleeves (11) of the transportation anchors into the faces of the side walls (10) facing the interior of the room unit and to provide in the roof panel (18) perforations (17) which lie close to the inner edge of the side walls and through which a lifting device can engage. For this purpose, the lifting device advantageously has a metal strip (16) or a traction rope, which is non-positively connected to a pin (15) inserted into the anchor sleeve (11). <IMAGE>

Title: Double-segment eccentric for clamping and closing
Inventor: FREIWALD EMIL
IPC: F16B21/02
Filed: 1982-03-02
Abstract: This invention relates to a base body which is of round shape and is flat towards the outside and has two cardioid-shaped rail slots inside it which are displaced by 180 DEG  and for their part anchor the clamping locks, as catchment rails, via a fine tooth system such that they are protected against running backwards through the teeth during a rotation of up to 180 DEG  at any final clamping point. The priority shown here is the closure force, which retains the force, is designed for a very small space depending on the size and load and [lacuna] with clamping locks which can be inserted from two sides and, in turn, result in a large region of action at the central rotation point, without a large exertion of force, up to the maximum lifting closure. The drawings show, in a structural manner, a clamping and closing eccentric in two half shells which are shown at F and A in Fig. 1 and are screwed to one another. Fig. 2 shows the clamping locks at B, C, D, Fig. 5 shows the clamping locks in the retaining rail at B and the rotating-key holder at D, and Fig. 4 finally shows the complete eccentric element, closed to the limit point. The entirety is [lacuna] in overall function in a versatile manner for closing and clamping, as the overall view of a double-segment eccentric shows in design terms. <IMAGE>
