Title: Process and apparatus for pressure swing adsorption
Inventor: FUDERER ANDRIJA
IPC: F25J3/04
Filed: 1983-02-08
Abstract: The bed utilisation and the product yield, especially in pressure swing adsorption processes designed for high pressure applications, are improved in that the cocurrent pressure reduction is ended at a relatively high intermediate pressure level. Additional void volume gas is liberated from each main adsorber bed by partial countercurrent pressure reduction prior to the conventional countercurrent release. This additional gas is passed to an auxiliary bed, which can simultaneously release gas at its outlet end, as a result of which the auxiliary bed is depressurised by the intermediate pressure level in the cocurrent flow. The gas released in this manner is passed to the outlet end of one or more auxiliary beds and/or one or more main beds for pressure equalisation and/or flushing purposes. The auxiliary bed belongs to an adsorber bed auxiliary group, which includes fewer and smaller beds than the main bed system. The auxiliary beds are not subjected to a higher pressure than the intermediate pressure level.

Patent DE-3314433-A1 (DE)
Title: Process for depositing an electrode and a protective layer on a substrate
Inventor: STAHL ROLAND DIPL ING
IPC: C23C14/16
Filed: 1983-04-21
Abstract: In a process for depositing an electrode and a porous protective layer on a substrate, the electrode material is deposited by vapour deposition or cathode-beam sputtering. Immediately after depositing the electrode material, the metal whose oxide is to form the protective layer is deposited in the same way as the electrode material and the entire combination is then thermally treated in air in order to achieve complete oxide formation. This process enables the plasma-jet technology normally used for the porous protective layer to be eliminated, and in addition, the structure of the electrode deposited beforehand is not stressed to the same extent as in the plasma-jet technology.

Patent DE-3320980-A1 (DE)
Title: Glass melting unit
Inventor: ROSS LUDWIG DIPL CHEM DR
IPC: C03B5/167
Filed: 1983-06-10
Abstract: A material which is suitable for the components of a glass melting unit which is employed in both continuous and batch processes comprises metallic zirconium. Due to the high corrosion resistance of zirconium, it is not necessary to use expensive noble metals during melting of aggressive substances. In the case of high-quality, optical glasses, an improvement in quality is achieved by a reduction in the formation of streaks (schlieren) and the prevention of the crystallisation of dissolved noble metals. In order to prevent atmospheric oxygen attacking the zirconium, the parts which are not wetted by the glass melt are either flushed by an inert gas or protected by a refractory covering containing a reducing agent. A further possibility is to carry out the melting under reduced pressure.
Patent DE-3323712-A1 (DE)
Title: Ball-valve housing
Inventor: NEMETZ JOSEF
IPC: F16K27/10
Filed: 1983-07-01
Abstract: Single-piece ball-valve housing for ball valves are made from one casting, one forging or in jobbing production by machining. Welded constructions are also known in which the housing in the central area and/or in the area between the two connection sides is welded together from a plurality of parts of differing wall thicknesses. The housings produced in this way are on the one hand expensive to manufacture and on the other have greater or lesser wall thicknesses and sometimes also relatively different geometric shapes in the area of the body housing, due to the individual methods of manufacture. These disadvantages are overcome by, e.g., manufacturing a housing body for a ball-valve housing from one pipe section, extruded part, pressed part or the like.

Title: Positive displacement machine, in particular epicyclic gear with integrated hydraulic motor
Inventor: BRAREN RUDOLF
IPC: F04C2/10
Filed: 1983-08-02
Abstract: A positive displacement machine, in particular a planet motor, having a housing (1, 2) with pressure medium connections (27, 30) for the supply and discharge of pressure medium, having a toothed central wheel (4) arranged in the housing (1, 2), which central wheel is coaxial with a driven shaft (11) (central wheel axis (O)) mounted in the housing (1, 2), having a toothed planet wheel (6) meshing with the central wheel (4) and thus, during its revolution, forming displacement chambers (13), and having a revolving control element (14) with control orifices (19, 20) which, during the revolution of the control element (14), establish alternating connections of the displacement chambers (13) with the pressure medium connections (27, 30). In order to avoid, as the number of displacement chambers (13) increases, having to provide a similarly large number of control orifices, which are expensive to produce and lead to excessive noise, the control element (14) has only two control orifices (19, 20) each extending over almost half its circumference, and the control element is driven at the speed of the planet wheel (6) around the central wheel axis (O) (Figure 1). <IMAGE>
Patent DE-3329590-A1 (DE)
Title: Method and device for harmonising a plurality of optical/optoelectronic axes of a sighting unit on a common reference axis
Inventor: SIEBECKER HANS DIPL ING DR
IPC: F41G3/32
Filed: 1983-08-16
Abstract: The method and the associated device for harmonising the optical/optoelectronic axes (4; 5; 18) of a sighting unit, consisting of a day viewing channel (3) and a combined thermal image/laser receiving channel (1) having an offset laser transmitter (2), on a common reference axis forms the subject matter of the invention. The laser radiation (9) reflected from the target impinges together with the radiation (11) from the target and the natural radiation (11) of the environment via the scanning mirror (12) on selected elements of the detector series arrangement (13), is optoelectronically converted and represented on the light-emitting diode arrangement (25). Via the rear of the mirror, the signals are projected on to the retina with the aid of the deflecting mirror (23) folded into the beam path. The visible radiation (19) imaged in the plane of the day collimating mark (21) likewise reaches the observer's eye when the deflecting mirror is folded out. The visible radiation (19) in the day viewing channel (3) can be observed when the deflecting mirror is folded out, by means of imaging in the plane of the day collimating mark (21). When observing the radiation on the side of the thermal channel output, the day collimating mark is replaced by the thermal image collimating mark (29) which, being reflected into the thermal image reproduction channel, is superimposed on the thermal image. In the harmonised state, it is displaced to the position of the day collimating mark. <IMAGE>

Title: Method for switching a piston pump with charging pump, and pump system operated according to the method
Inventor: KLOPP RAINER DIPL ING
IPC: F04B23/10
Filed: 1983-09-27
Abstract: A piston pump with a charging pump is to be provided with the ability of being started up and run down, with the rotational speed decreasing, without the inlet pressure provided by the charging pump in the suction line of the piston pump decreasing substantially in the process. This avoids the risk of cavitation and protects the clutch during switching. This is achieved by both pumps being driven by a motor (8), the charging pump (2) being maintained, via a fly-wheel/ clutch combination (4, 5), at operational or nominal speed even if the piston pump (7) is briefly operated at low speed, in order to maintain the inlet pressure required for satisfactory operation of the piston pump (7). <IMAGE>

Patent DE-3335578-A1 (DE)
Inventor: THORWARTH RUEDIGER
IPC: H05K3/22
Filed: 1983-09-30
Abstract: In the case of printed circuit boards which are suitable for making subsequent changes in connections, in each case two superimposed terminal surfaces (1, 2) on the outer layers are electrically conductively connected to one another by a conductive path (3). If a terminal surface (1) or a wrapping pin (4) soldered therein is then required as a supporting point for a wiring change, the connection to the other terminal surface (2) must be interrupted, i.e. the conductive path (3) must be severed reliably, without damage to the printed circuit board. To this end, contact is made with the terminal surfaces (1, 2) or, if required, also with the wrapping pin (4) with the aid of electrodes (5, 8), the conductive path (3) being completely burned through by resistance heating. A current pulse suitable for the resistive burning through is generated in this case by a control unit (12) connected to the electrodes (5, 8). <IMAGE>
