Patent DE-3134977-A1 (DE)
Title: Compressor
Inventor: KALTENTHALER WOLFGANG
IPC: F04B39/04
Filed: 1981-09-04
Abstract: In compressors, in particular in single-cylinder reciprocating compressors, the stroke movements of the piston cause pulsations in the crankcase, which are generated by the excess pressure produced during the downward movement of the piston in the crankcase. In order to prevent this, it is known to arrange vent ducts which connect the crankcase to the intake chamber. Since, owing to the negative pressure, oil constituents may reach the intake chamber through the vent ducts, ducts have been provided according to the invention, which allow the oil to flow back into the crankcase.

Patent DE-3146359-A1 (DE)
Title: Apparatus for welding sealing profiles or the like of plastic
Inventor: SCHENK HERBERT
IPC: B29C65/00
Filed: 1981-06-11
Abstract: The invention relates to an apparatus for welding sealing profiles of plastic, which are used for example for window or door seals. Until now, the ends of the sealing profiles intended for welding have been mechanically cut to size for a mitre joint manually by means of a knife. Since, however, the sealing profiles generally consist of very soft-flexible material, the pressure of the knife often causes deformations which result in unsmooth cut surfaces and consequent deficient welded joints. The invention solves this problem by providing the welding apparatus with two laterally spaced-apart, parallel-guided, knife-shaped elements (27), which in the withdrawn position (starting position) can be heated up in gaps (24) between fixed heating blocks (18) and then can be moved together into the space between the mounts (11, 13) for the combined making of separating cuts at the ends of the sealing profiles (10) and initial melting of the same for the purpose of subsequent welding. After returning the knife-shaped elements (27) into the starting position, the initially melted ends of the sealing profiles (10) are pressed against each other and thereby neatly welded to each other. The invention is used principally for cutting to size and welding sealing profiles of plastic for window and door seals. <IMAGE>

Title: Pipe coupling
Inventor: OEHRNELL OLOF
IPC: F16D3/50
Filed: 1981-12-03
Abstract: The invention relates to a coupling between an inner pipe and an outer pipe concentric to the latter, comprising a body arranged between the mutually facing circumferential surfaces of the two pipes and consisting of rubber or a similar flexible material. According to the present invention, the flexible body is permanently connected to the circumferential surface of the inner pipe by vulcanisation or the like, while it engages by means of tongues and/or grooves in corresponding grooves and/or tongues on the circumferential surface of the outer pipe, and the flexible body is thicker in the unloaded condition than the difference between the inner radius of the outer pipe and the outer radius of the inner pipe, with the result that, in the coupling position, it is compressed between the two pipes. In addition, the flexible body has a conical taper at at least one end on the outside provided with the tongues and/or grooves.

Title: Corner connection between a vertical, profiled column and a horizontal board, preferably for tables, cabinets and the like
IPC: F16B12/46
Filed: 1982-06-29
Abstract: In unit furniture for self-assembly, which can be dismantled, the visible edges are rounded off. The surfaces of the furniture are frequently provided with a film which creates folds in the corner region during application. The corner connection according to the invention consists essentially of a vertical attachment end which can be inserted into the internal space of the column which supports the furniture piece, a flange strip which is provided with through-holes for retention and attachment of a board, a centre piece which is located in a recess in the board, and a screen which covers the corner recess of the board horizontally and vertically. During production of the recess in the corner region of the board, the film which is provided with folds is also detected so that, during application of the film, unavoidable formation of folds can be ignored. The method for producing the board is termed the post-forming method, in the relevant branch of industry. <IMAGE>

Title: Method and arrangement for direction finding on ships
Inventor: MOENICH GERHARD DR ING
IPC: H01Q25/02
Filed: 1982-07-02
Abstract: For finding the direction of an electromagnetic wave on ships, particularly in the case of directions of incidence broadside on to the longitudinal axis of the ship, two frame antennas are arranged spatially separate from one another in such a manner that the nulls of their patterns point in the direction of the line joining bow to stern: the antenna voltages of the two frame antennas are compared with respect to their mutual phase angle and from the phase difference measured, the angle of incidence of the wave is determined. The back scattering from back scatterers located in the line joining bow to stern such as, for example, masts of the ship, does not interfere with the direction finding.

Patent DE-3243050-A1 (DE)
Title: Drive for the main spindle of a horizontal boring and milling machine
Inventor: LIEBERS JUERGEN DIPL ING
IPC: B23Q5/14
Filed: 1982-11-22
Abstract: The aim of the invention, which relates to the transmission of the main drive of a horizontal boring and milling machine as well as its attachment to the spindle head, is to improve the service properties of the said machine and to reduce the manufacturing cost of its main spindle drive. The objects, which are to reduce the noise generation in the transmission, to largely prevent the propagation of noise via the walls of the spindle head, to mount the transmission completely outside the spindle head, to remove the effect of tooth forces on the loaded main spindle and to prevent the thermal effect on the spindle head by the transmission oil, are achieved by the transmission being encapsulated in a housing which, as a complete, preassembled and pivotable unit which can be put into the spindle head, contains all drive elements. The last shaft of the transmission is a hollow shaft through which the main-spindle part projecting out of the main bearing arrangement passes in a concentric and axially displaceable manner (Fig. 1). The housing of the transmission is split, the parting line running through the centres of the bearing bores of the individual transmission shafts. The invention can also be used on other machine tools. <IMAGE>

Title: Drainage valve for a blood pressure measuring device
Inventor: STIEBLER FRANZ
IPC: A61B5/0235
Filed: 1983-04-15
Abstract: The invention relates to a drainage valve for a blood pressure measuring device having a housing (2), a chamber (4) with an inlet (12) and and outlet (90) for the fluid to be drained, and an elastically deformable part (82) located in the chamber. The elastically deformable part has an essentially cylindrical bore (84) which is at least partially located in the outflow path of the fluid. In the bore (84) a rigid adjustment element (70) which corresponds to the bore and is arranged so as to be rotatable and/or axially displaceable relative to the bore (84) is located. The cross-section of the adjustment element is designed as an outflow channel (77, 78) over a specific length toward the outlet (90). At the same time the cross-sectional circumference of the adjustment element (70) in its lower (88) region is dimensioned, relative to the cross-section of the cylindrical bore (84) and the hardness of the material of the elastic part (82), so that it is always possible for a minimum fluid quantity to flow out. The outflow behaviour, then, is improved further in respect of, on the one hand, constancy of the drainage speed and, on the other hand, the adjustment range of the drainage speed, in that the adjustment element (70) projects at least partially out of the bore (84) into the chamber (4). <IMAGE>

Patent DE-3345757-A1 (DE)
Title: Two-part cooking vessel
Inventor: SCHAWALDER ALBERT C
IPC: A47J36/36
Filed: 1983-12-17
Abstract: The invention relates to a two-part cooking vessel, in which a saucepan of conventional type is surrounded with a small spacing by an annular second cooking vessel. Due to the gap between the two cooking vessels, the air heated by the heating surface or heating flame rises and gives off the heat to the side wall, such that the heat generated is utilised in a better manner. In an embodiment preferred for use on hot plates, the inner side wall of the outer cooking vessel has a depressed zone at the top and the inner cooking vessel has a stem-type handle which is arranged and dimensioned in such a way that, in the normal operating state, it is inside this recess but, when said handle is swivelled laterally, the inner cooking vessel is raised laterally. As a result, the direct heat transfer from the heating surface to the inner vessel is immediately reduced and any boiling over is prevented.
