Patent DE-3401198-A1 (DE)
Title: Improved plane surface sealing by means of pressure compensation in rotary piston machines
Inventor: WINKLER HANS-JOACHIM PROF DR I
IPC: F01C19/08
Filed: 1984-01-14
Abstract: The internal return flow losses in rotary piston machines are largely caused by the fact that between the rotors and the facing plane surfaces a considerable widening of the gap arises during operation, because the working pressure causes elastic or even plastic outward buckling of the plane surfaces. The invention thus proposes to design each of the two opposite flange sections as a double flange, a cavity within the double flange communicating directly with the discharge side of the machine. The pressure buffer thus produced compensates the pressure forces acting in the interior of the delivery chamber, so that the planarity of the sealing face is largely maintained and only the outer flange section can buckle. By overcompensating, it is even possible to cause the plane surface to bear against the rotors.
Patent DE-3406736-A1 (DE)
Title: Metal-detection system
Inventor: BERGER LUTZ
IPC: G01V3/10
Filed: 1984-02-24
Abstract: The invention relates to a metal-detection system having transmitting and receiving coils which are arranged relative to one another in such a way that magnetic decoupling prevails, and having an electronic evaluation system. The solution is characterised by   a) the measurement of a disturbance in the two-dimensional field using magnetic fields vertically assigned to one another,   b) two transmitting coils and one receiver coil and   c) phase and amplitude compensation.   The metal-detection system according to the invention is distinguished by a thorough digitisation of its subassemblies, which leads to drastic reductions in the problems of drift and guarantees exact reproducibility of the measurement operations. All the trigger pulses and reference signals are obtained from the fundamental frequency (e.g. 10 MHz quartz oscillator) of the transmitter unit. It is thus impossible for the tuning to occur on the basis of temperature variations or aging such as occur with RC-equipped timing elements. The essential novel aspect of the system is represented, however, by the rotating exciting field which eliminates the problems of orientation.

Title: High-pressure long-stroke platen press without press frame
Inventor: POEHL ANDREAS
IPC: B30B15/04
Filed: 1984-02-25
Abstract: A high-pressure platen press with long stroke and self-adjusting press platens, without press frame. In addition to the conventional pressing jobs such as thermoforming, stamping and compression moulding of large surface-area articles, this press is also suitable for fine jobs such as welding in between thermoplastic films, synthetic resin coating and structural embossing. The central part of this press consists of two (or more) press platens having semi-circular reverse sides (Fig. 1, 1 + 2). A high- pressure hose (Fig. 3) or similar expansion body is wound around these press platens. With the inflation of this hose, only the hose circumference or the shape, but not the length, can be changed. These hoses, which necessarily expand inwards, press the two or more press platens together. The reaction forces or supporting forces bear as tensile force on the outer skin of the hose. A press frame and conventional cylinders are dispensed with. <IMAGE>

Title: Encapsulated, gas-insulated medium-voltage switching installation having a pressure-relief device
Inventor: KRAEMER WILHELM
IPC: H02B13/065
Filed: 1984-03-30
Abstract: For a gas-insulated medium-voltage switching installation which is encapsulated in a gas-tight manner, a pressure-relief device (27) is proposed which operates in the manner of a rupture safety device and is formed by a closure cover (28), which is axially displaceable like a piston, in an opening, which guides the closure cover and is sealed by at least one circumferential sealing element (42...47), in a housing element (12) which is used for encapsulation, as well as being formed by at least one spring clip, preferably, however, two or more spring clips (34, 35), which is located outside the encapsulation, holds the closure cover in its position which closes the opening in a sealed manner in normal installation operation, is subject to predetermined prestressing and is bent close to its clamping-in point. These spring clips withstand, in a manner such that they spring back, a temporarily occurring, slowly rising gas pressure in the interior of the encapsulation until a response pressure is reached - even in the event of axial displacement of the closure cover in the order of magnitude of several millimetres - while in contrast, in the event of a further pressure rise above the response pressure, especially, however, in the case of a very rapid, virtually explosive pressure rise and an axial displacement of the closure cover beyond its sealing axial position, caused thereby, they deform permanently at their bend points (36) and do not guide the closure cover back into its sealing axial position again. <IMAGE>

Title: Method for fabricating a superconducting contact
Inventor: BEST KARL-JUERGEN DR
IPC: H01L39/02
Filed: 1984-04-07
Abstract: In the case of superconducting connectors it is necessary to provide, for the purpose of connecting ends of conductors, superconducting contacts which retain their superconducting properties even at high magnetic fields. A simple method of preparing these contact sites in such a way that they form, together with the conductor, a superconducting layer upon a final heat treatment below 800 DEG C consists in a powder mixture (5) being placed inside a sealed and compressed sheath (4) and being subjected inside the sheath (4) to a heat treatment in order to form the superconductive material. <IMAGE>

Title: Arrangement for converting signals, particularly video signals, into binary signals
Inventor: GERNER GUENTER DIPL ING
IPC: H04N1/403
Filed: 1985-09-26
Abstract: When converting video signals into binary signals, it is desirable to generate the logic states of the binary signal in dependence on different criteria. According to the present invention, the video signal is conducted via a high-pass filter (DLU, DFB), the output signal of which is compared with an edge threshold value by an edge comparator (FKP). Depending on the result of the comparison, a binary edge (FL) signal and a sign (VZ) signal is output. Furthermore, the amplitude of the video signal is compared with an amplitude threshold value and a binary signal (SW) is generated depending on the result of the comparison. Amplitude, edge and sign signal (FL, VZ, SW) are logically combined in a logic circuit (LGS) in accordance with an arbitrary logic function. The binary video signal (DBS) is picked up at a bistable flip flop (BK) connected to this logic circuit. The invention is used in image analysis. <IMAGE>

Title: Disposable insert for problem waste incineration containers
Inventor: FABRITZ GERHARD
IPC: A61B50/36
Filed: 1986-05-09
Abstract: Problem waste consists of amputated body parts, organs, infectious tissue, pet carcasses, etc., from hospitals and research institutes and is deep-frozen in containers of chipboard, plastics or corrugated cardboard for incineration in crematoria. In this procedure, damage is caused to the crematorium furnace by rapid thawing of the problem waste and the associated liberation of water, and the premature incineration of the container bottoms. This is to be avoided by a disposable insert to be inserted into the said containers. This is preferably of rectangular box shape, according to Figs. 1 and 2, and consists of pulp board. Fig. 1 shows the front elevation of a disposable insert and Fig. 2 the plan view thereof. The walls 1 and the bottom 2 are coated with a highly absorbent layer 3 of cellulose packing wadding, which is circumferentially bonded to the upper edge 4 on the insides of the walls 1. Provision is also made for the disposable insert to be coated with two superposed layers of cellulose packing wadding. Their projecting ends 5 serve to cover the problem waste introduced. The function of the cellulose packing wadding is to absorb the water liberated by the action of temperature. The layer 3, which is thus thoroughly moistened, not only prevents the undesirable occurrence of dripping but delays the rapid combustion of the entire bottom area of the incineration container. <IMAGE>
