Title: Resilient attachment bracket
Inventor: LECHNER FRANZ ING GRAD
IPC: F16B5/06
Filed: 1981-11-30
Abstract: In order to connect a stack of essentially plate-shaped parts (1, 2, 3, 6) with a retention force which is essentially independent of tolerance-related thickness variations of the stack of parts, a resilient retaining bracket (4) is used which is formed by a helical spring (4b) having a hook (4c, 4d) integrally formed thereon. The hook (4d) engages through recesses (1a-3a) in the stack of parts and, in the operating position, preferably rests on the outer surface of the stack of parts (1-3). In order to create an adequate contact surface for the resilient bracket, at least one helical turn (4a) is integrally formed on the spring end opposite the hook (4d), the diameter of which helical turn exceeds the unobstructed width of the recess (1a) in the plate (1d) adjacent to it. To the extent that one of the plate-shaped parts consists of a relatively soft material, it can also have a recess (6a), like a blind hole, into whose elastic walls the hook (4d) engages. <IMAGE>

Title: Two-piece, especially metallic insulating coupling
Inventor: DIJK LAMBERTUS JACOBUS VAN
IPC: F16L25/02
Filed: 1981-12-02
Abstract: The invention relates to a two-piece insulating coupling, which is preferably used between a gas pipeline outside a dwelling and a gas meter inside the dwelling, so that perfect electrical insulation is ensured. To this end, a two-piece metallic coupling is provided which is composed of a nut and a coupling part. The nut is provided internally with a recess for holding a cylindrical insulating ring, whose height is greater, or at least equal to, the total height of the coupling flange, which can be tightened, on the coupling part, of the flange of an insulating ring which is located in a cylindrical recess on the coupling part and of the gas sealing ring which rests against the coupling flange. The insulating rings are arranged in such a manner that, when the tightening forces are exerted, the parts of the nut remain completely electrically insulated from the metallic coupling part, in both a radial and an axial direction, which metallic coupling part is connected to a mating coupling part using a further insulating ring, in order to make the nut gastight.

Title: Antenna energiser having a plurality of wave types
Inventor: SCHEFFER HANS DIPL ING
IPC: H01Q13/02
Filed: 1982-02-05
Abstract: In the case of an antenna energiser having a plurality of wave types, especially the H21 and/or HE21 wave, the invention is based on a round supply waveguide and a conical horn emitter in the region of the supply opening. Energising of the H21 wave which has little frequency dependency in phase and amplitude is achieved in that the axes of the supply waveguide (1) and of the horn emitter (2) are arranged radially offset with respect to one another by the dimension R and, in addition, form a finite angle  alpha  with respect to one another, the diameter D of the circular opening cross-section (3) of the horn emitter (2) being dimensioned such that the higher wave type H21 and/or HE21 is capable of propagation. The horn emitter cross-section may be continuously circular or may merge into an elliptical cross-section towards the aperture. The inner wall of the energiser may have a groove structure, at least in places. In addition, the inner wall of the horn emitter may merge towards the aperture into a profile which differs from a straight line (e.g. a bell shape). <IMAGE>

Title: Compensation device for axial expansions of pipelines
Inventor: JESCHKE IMMANUEL
IPC: F16L51/02
Filed: 1982-04-22
Abstract: In the case of a compensation device for axial expansions of pipelines, consisting of two pipe pieces which are connected to one another by means of a folding bellows, it is intended to achieve the object of creating a compensation device for axial expansions, which compensation device is of extremely simple construction, is very robust and is protected against lateral and radial displacements as a result of its construction. The invention achieves this object in that the external diameter and internal diameter of the one pipe piece are larger than those of the other pipe piece, in that the pipe pieces are pushed into one another for the length of the folding bellows, in that the pipe piece having the smaller diameter has an external flange whose external diameter is equal to the internal diameter of the pipe having the larger diameters, in that the pipe piece having the larger diameters has an internal flange whose internal diameter is equal to the external diameter of the pipe piece having the smaller diameters, in that the folding bellows are arranged in the intermediate space between the two pipe pieces and the two flanges, and in that the folding bellows are attached to the pipe pieces in the immediate vicinity of the flange, or are attached to the flange itself.

Patent DE-3229951-A1 (DE)
Title: Drive unit with a driving engine and a hydrodynamic brake
Inventor: SPITZER OLAF
IPC: B60T1/087
Filed: 1982-08-12
Abstract: A drive unit consists of a driving engine and of a gear to which a hydrodynamic brake is assigned. This brakes possesses two flow circuits. One has the conventional design with rotor and stator blade ring, whilst the other has a rotor connected to the output shaft and a stator which is driven by the engine, but which rotates in the opposite direction to the rotor. This second flow circuit, by its braking effect increasing towards zero driving speed, compensates the parabolically decreasing braking effect of the first flow circuit. The torque transmission from the engine to the stator of the second flow circuit takes place, for example, by means of a planetary gear, so that an adding effect of the torque introduced by the engine together with the torque generated hydraulically by the flow circuit occurs. The rotational speed of the stator is increased, the brake can have smaller dimensions, and the braking torque is increased at a low driving speed. <IMAGE>
Patent DE-3241500-A1 (DE)
Title: Cable containing at least one conducting element in a protective covering
Inventor: BERNDT JUERGEN DIPL ING
IPC: G02B6/44
Filed: 1982-11-10
Abstract: In a cable containing at least one conducting element in a protective covering, in particular optical cable, the protective covering contains cavities into which a substance has been introduced which is capable of swelling in the event of ingress of moisture and which contains salts of alginic acid. To solve the problem of achieving a rapid plug formation to obtain longitudinal water tightness and also of preventing a gradual continued creep of the moisture, it is proposed that the substance which is capable of swelling is composed of a mixture of water-soluble salts of alginic acid with cation-forming organic or inorganic salts.
Patent DE-3244209-A1 (DE)
Title: Seal for sealing against hydraulic fluids, preferably a sealing scraper element
Inventor: BUCHER HANS DIPL ING
IPC: F16J15/3232
Filed: 1982-11-30
Abstract: The seal provided for sealing against hydraulic fluids has a sealing body with two axially spaced scraper lips. Projecting outwards from the sealing body, transversely to the axis of the seal, is a sealing part which rests sealingly, under prestress, against a counter sealing surface. The sealing part forms an air-side closure of a cavity which is open towards the fluid end of the seal. When the pressure of the fluid in the cavity exceeds the prestressing force of the sealing part, the sealing part rises from the counter sealing surface, allowing the fluid to escape to the outside. This provides an optical signal that a primary seal which cannot be seen is defective and should be replaced.
Patent DE-3244280-A1 (DE)
Title: Separating device for sheet-like data carriers
Inventor: BLOECHL HANNS
IPC: B65H3/06
Filed: 1982-11-30
Abstract: In the separating device, the pile of sheets (5) bears spring pressure from below against a stop (4b, 4c) which is rigidly connected to the machine, and two feeding rollers (7) which can be swivelled onto the top sheet of the pile are arranged on a common shaft (8) at some distance from each other. The two feeding rollers (7) are swivelled by means of a reciprocating driving element (10), which is preferably driven by a rotating cam disc (17). To permit setting of the separating device to various paper thicknesses and to ensure that sheets are not drawn in at an angle, an individually settable adjusting element (11) is connected into the swivelling mechanism of each of the two feeding rollers (7), so that the initial positions of the two feeding rollers can be altered. <IMAGE>

Title: Sleeve-type draw-back device for the dismantlable assembly of two elements, especially furniture parts
Inventor: BEAUX DOMINIQUE
IPC: F16B12/20
Filed: 1982-12-01
Abstract: The invention relates to the furniture industry. It is aimed at a cylindrical sleeve which is inserted with a close fit into an orifice drilled on the surface of an element to be assembled, said sleeve being perpendicular to a draw-back dowel, and said dowel being introduced into said element and fastened to the second element of the assembly, characterised in that the sleeve is bifurcated in a supporting manner on the body of said dowel and comprises a special orifice which, on the one hand, provides the passage and lateral displacement of a screw with countersunk head, which is screwed into the body of said dowel, and which, on the other hand, forms a support inclined relative to the lower face of the said countersunk head, whilst the screw connection thereby causes a transverse displacement of the sleeve along the dowel and consequently causes the two elements to be drawn back together. <IMAGE>

Patent DE-3247564-A1 (DE)
Title: Device for the metering of a predetermined volume of pourable material, especially for a packaging apparatus
Inventor: BAUR WALTER DR
IPC: B65B1/36
Filed: 1982-12-22
Abstract: Product to be metered is conveyed via a feed device, for example vibrating troughs (5, 9), to a measuring bowl (2) which is closed by means of a bottom flap (15). The filling height in the measuring bowl (2) is sensed by means of an infrared probe (3). When the desired filling height is reached, a control unit (26), to which the infrared probe (3) is connected, causes a further product feed to be shut off, for example as a result of the actuation of a closing flap (12). When a following packaging machine (V) requires a product portion, the bottom flap (15) is opened and the product portion contained in the measuring bowl (2) falls into the packaging machine (V). The contactless sensing of the filling level in the measuring bowl (2) avoids mechanical stress on the product. The device is therefore well suited for the volumetric metering of delicate products. <IMAGE>

Patent DE-3306383-A1 (DE)
Title: Cavity-forming wound dressing for the ambulant treatment of the wound space climate dressing
Inventor: SCHELOWSKY MICHAEL
IPC: A61N1/10
Filed: 1983-02-24
Abstract: The ambulant treatment of defect wounds with the usual ointment dressings may be associated with disadvantages that delay healing due to inadequate protection with tenderness, sticking of the dressing with scab and obstructed entry of air. Previous patents relating to formation of a vault over the wound with venting and drainage are extended by the "wound space climate dressing" in two healing-promoting fields outside traditional medicine:   1. The dressing part forming a vault over the wound is a lattice permeable to ethereal phytoactive substances emerging from an impregnated support. At the same time, the air of the wound space climate serves as the transport medium for the gaseous molecules of the healing-promoting substances down into the depth of the wound. 2. The vaulting lattice of an electrically conductive material, connected to a low-voltage current source, forms an ionosphere for the wound in order to meet the presumably increased demand for positive ions for cell regeneration and sterility. The atmospherically electric constant field thus formed makes it impossible for pathogenic organisms to stay alive. Bacilli tetani, in particular, are prevented from producing neurotoxins, which are produced on exclusion of air, before they are killed by the leucocytes, under certain circumstances without prophylactic immunisation.   The "wound space climate dressing" appears suitable for ambulant treatment in areas without the latest medical equipment where natural healing methods must be improvised in order to be effective.
