Title: Low-pressure natural gas compression - by utilising high-pressure natural gas energy in swirling flow injectors
Inventor: MIKA GYOERGY DIPL CHEM ING
IPC: F04F5/18
Filed: 1978-11-17
Abstract: Natural gas of low pressure is compressed by utilising the pressure energy of natural gas or of a by-product gas at high pressure by allowing the natural gas to expand in a swirling-flow injector. Gas released from the separated fluid and/or from a flare separator is also directed in the injector. The pressure release of he liq., separated from natural gas takes place in not more than five stages; the gas from the second and third stage are injected in the first or second swirling flow injector. This eliminates the difficulties with mechanical compressors and achieves higher compression ratios than are possible with gas jet compressors.

Title: Material pair adhesive property testing under shock loading - using weighted trolley moving under gravity down incline from rest position
Inventor: NEHAMMER ROBERT
IPC: G01N19/04
Filed: 1979-06-05
Abstract: A device for testing material pair adhesive properties is applicable to precision assemblies such as keyboards using elastomer damping elements and where excessive adhesion between surfaces degrades performance. It enables examination of different influencing parameters on adhesion. One part of the combination test piece is clamped to a force measurement device whilst the other has an attached rod with a stop to which defined shock forces can be applied in the separation direction. The adhesive force and the time history of the separation process are recorded. The defined shock force is applied by a weight gravity consisting of a trolley through which the rod passes moving under gravity from rest down an incline. The force may be adjusted by varying the distance of travel, magnitude of a counter-wt. etc.

Title: Sheet e.g. banknote authenticity tester - measures check parameters opto-electrically under object position-dependent evaluation control
Inventor: NAKANURA YASUSHI
IPC: G07D7/12
Filed: 1979-11-12
Abstract: An authenticity tester for documents such as tickets, securities, banknotes etc. is a high accuracy device requiring no accurate setting of individual automatic gain control circuits in its evaluation circuitry and whose accuracy is not degraded by test object transport speed variations. Object conveyor path illumination sources are controlled by timing signals dependent an object position detectors. Optoelectronic transducers (48,50,52,58,60,62) produce electrical signals varying in amplitude according to the intensity of the light transmitted through or reflected from the object. The transducer signals are integrated and the result evaluated w.r.t. a stored integrated signal corresp. to a genuine article by comparison. This enables the object to be classified as genuine or false. The position sensors (36,40,54,56) are placed along the object path.

Title: Panel for sprung floor of gymnasium - has continuous layer of plastics foam with integral downward struts as supports
Inventor: DAEHNE ROLF
IPC: E04F15/22
Filed: 1980-05-31
Abstract: Panel consists of a continuous layer beneath the floor with downward projecting columns or struts integrally formed with this layer of the same closed-cell plastics foam. The cross- section of each of these struts increases from the bottom towards its junction with the continuous layer. The struts act as resilient elements and provide a gradual increase in resistance to an applied force or impact without any sudden step change. Pref. the density of each strut increases from its free end (bottom end) towards the continuous layer. The layer together with struts may be formed by hot embossing of a panel made from the plastics foam. Preferred ratio of the total depth of the layer and the struts to the depth of the continuous layer is 1.00-2.25, more specifically 1.5-2 (approx. 1.75). Preferred ratio of the total area to that of the strut bases is 3-13, more specifically 5-11 (7-9). Assembly has improved sprining characteristics over prior art designs.
Patent DE-3023393-A1 (DE)
Inventor: BRINKMANN HEINZ
IPC: B29C48/03
Filed: 1980-06-23
Abstract: A temperable screw casing for a twin screw extruder for processing plastics comprises a supporting member and wear resistant liner disposed therein. The liner has a spectacle shaped bore accommodating both screws of the extruder. The supporting member, which engages around the liner, takes over the reinforcing function of the screw casing. Low technical manufacturing cost and satisfactory tempering of the screw casing is achieved by providing the liner with a circular external cross section, surrounded by a supporting member which has a circular internal recess. Axial tempering holes are provided in wedge shaped projections which extend into the spectacle shaped bore of the liner. Axial tempering holes are disposed opposite one another in the supporting member, at the sides of the spectacle shaped bore of the liner. These result in individual tempering systems, by which the liner and supporting member can be tempered independently.
Patent DE-3026811-A1 (DE)
Title: Housing for interference suppression circuits - comprises perforated metal casing into which components are fitted and cast in resin
Inventor: RISTIG EBERHARD DIPL ING
IPC: H05K5/06
Filed: 1980-07-15
Abstract: The design ensures easy soldering of the lid onto the case and also prevents distortion of the case during resin filling. To achieve these objectives both the lid and case (2,1) are made of perforated metal. The components (3,4,5) are mounted inside the case (1) and connected to the appropriate leads (7,8) mounted in glands on the lid (2). The lid is then pushed into position and the seams between lid and case soldered up. The assembly is then filled with casting resin which enters through the perforations. By making the casting operation the last one, the joining seams between case and lid are not distorted by the casting process. Also the surfaces to be soldered are not contaminated with resin necessitating cleaning before the seams can be soldered.

Title: Noise screen wall concrete slab mounting on posts - involves right angled side screw bolts with protruding heads, permitting adjustment
Inventor: WEISZFEILER EDGAR DIPL ING
IPC: E04B1/82
Filed: 1980-08-16
Abstract: Insulating elements, shaped as rectangular concrete slabs, are held by flanges of upright supports, of I-shaped cross- section, clamped into bases at intervals, to form a wall along traffic routes, or similar, for noise protection. In the area of its eventually upright edges each slab (1) has a rotatably mounted screw bolt (3), or more than one, more or less vertical to the slab plane, with head protruding beyond the slab surface. A nut can be located on each screw, between the screw head and slab surface. After setting slabs in position, screw bolts can be unscrewed from slabs until they fit firmly against the inside faces of the post flanges. Slabs can be quickly pushed into place between flanges, quickly secured without risk of damage, then adjusted sideways, and provide for considerable tolerances.

Patent DE-3101138-A1 (DE)
Title: Heat pump with heat exchangers
Inventor: VONHOFF JUERGEN
IPC: F25B39/02
Filed: 1981-01-15
Abstract: The invention provides heat pumps which have triple heat exchangers on the evaporator side and/or on the condenser side. These heat exchangers are designed so that, on the input side, they can transmit the heat energy of two heat sources, for example a roof absorber and an earth absorber, simultaneously or individually to the evaporator side. There can likewise be provided on the heat-output side a triple heat exchanger which transmits the heat energy of the condenser to the heating circuit or to the service-water circuit or to both at the same time. Especially where coaxial condensers are concerned, it is of particular advantage to have such a pipe arrangement or construction that, in the event of leaks in the pipe carrying the refrigerant, no refrigerant can pass into the service-water circuit. These triple heat exchangers according to the invention are shown in the description and drawing of the Patent Application.

IPC: D02H13/30
Filed: 1981-03-06
Abstract: Warp beam for a thread warp, especially for a thread warp consisting of smooth, non-twisted and sized polyester yarns.
