Title: Circuit arrangement for the coded output of medical pulse (sampled) signals
Inventor: STIEGLER FRANK DIPL ING
IPC: A61B5/087
Filed: 1988-08-30
Abstract: The invention relates to a circuit arrangement for the coded output of medical pulse signals. This coder circuit is coupled via two-pole measured value outputs to a peripheral microcomputer processing unit belonging, for example, to ventilators for anaesthesia and therapy. The aim and object is to prepare digital signals with additional information in such a way that it is possible to detect pulse signals belonging to a breath, and that defective pulses are filtered out. According to the invention, the object is achieved with the aid of two programmable low-power operational amplifiers which are connected via their control inputs, programming resistors, invertors and a differential element to the output of a breath-detecting circuit, and are connected to one another via a diode and are led on the output side to the circuit output. <IMAGE>

Patent DE-3834473-A1 (DE)
Title: Sleeve
Inventor: KNAEBEL HORST DIPL ING
IPC: B23B23/02
Filed: 1988-10-11
Abstract: The invention relates to a sleeve with a displaceable piston for clamping workpieces against a suitable abutment, for example in a measuring machine. It is frequently desired to allow the workpiece to rotate in its set-up or in its holding device in order to permit continuous checks of the outside diameter at a measuring point. According to the invention, therefore, a sleeve (10) is proposed whose piston (22) can be pneumatically displaced with its centring taper (24) in a guide tube (18) and can be set against the workpiece. In its rear area, the piston (22) is connected to a drive bush (48) which partly surrounds it and is provided with an external tooth system (50). By a suitable drive pinion or a corresponding toothed belt, for example, the sleeve (10) and the workpiece clamped with it and to be checked can be rotated. For setting against the workpiece, the piston (22) is pneumatically loaded against the force of a helical tension spring (38). After the load is relieved, the piston (22) automatically returns with its centring taper (24) into a protected position in a protective cover (74). <IMAGE>
Patent DE-3836758-A1 (DE)
Title: Pocket calculator with a combined length-measuring device (instrument)
Inventor: BAYER ALFRED
IPC: G01B3/12
Filed: 1988-10-28
Abstract: Since it is the case that in many length measurements the measurement results have to be further processed mathematically in order, e.g., to convert a scale or to determine a price, it is necessary after a length measurement firstly to note the values and input them into a computer. There is always a need for two devices, since a metre rule or a tape measure have no direct communication with a computer. These functions can be united by combination with a pocket calculator and a length-measuring device. The electric pulses from the length-measuring device are transmitted to the calculator. The measurement result can be further processed mathematically. This combination can be used in a versatile way as a compact instrument.

Title: UV light for the degradation of pollutants, in particular of halogenated hydrocarbons
Inventor: MASSHOLDER KARL F DR
IPC: A62D101/22
Filed: 1989-02-07
Abstract: The invention relates to a process for the degradation of halogenated organic substances in liquid and/or gaseous effluents by irradiation, in particular in natural ground waters, industrial waste waters and industrial plants which is characterised in that the effluents are treated with UV light, preferably low-pressure UV light. The process according to the invention produces substantial degradation of the organically bound halogen and also breakdown of the organic compounds to give carbon monoxide and/or carbon dioxide and thus also permits the removal of contaminants present in trace amounts, such as pesticides, herbicides and chlorinated hydrocarbons.
Patent DE-3907432-A1 (DE)
Title: Control arrangement having a microcomputer for household appliances
Inventor: LUTHE WINFRIED
IPC: G05B19/042
Filed: 1989-03-08
Abstract: In the control arrangements having a microcomputer for household appliances in use nowadays, the programme selection and operating functions are entered by the user mechanically or electronically, the microcomputer normally communicating with its peripheral devices via digital inputs and outputs. In so doing, it is a significant disadvantage that a plurality of signal leads and corresponding encoding and decoding stages are necessary. In a control arrangement of this type, so that the number of signal leads can be reduced, different voltage or resistor values are assigned respectively to the input device having the different switches or switch positions. By this means, the selected function is unequivocally identifiable and the analog signals thus formed are fed to the microcomputer via an analog-digital convertor stage. By means of this design, more than 20 switches or switch positions can be unequivocally identified by the microcomputer in a trouble-free manner. <IMAGE>

Patent DE-3939840-A1 (DE)
Inventor: MILOSEVIC ZELJKO
IPC: A61B17/12
Filed: 1989-12-01
Abstract: The implantable occluder is designed for the temporary closure of arteries, especially the hepatic artery, for temporary liver de-arterialisation. It comprises a diaphragm securable to the artery which limits a chamber (2) and can be deformed by the supply of pressurised fluid via a catheter (9) connected to the chamber (2) with the aim of reducing the cross-section of the artery to zero by exerting pressure. A particularly delicate application defined in relation to the pressure can be obtained by making the deformable diaphragm as the inner limiting wall of a chamber (2) forming a hollow cylindrical body (1); in addition, the body is fitted with an axis-parallel separating slit (8) facilitating its application to the artery. Moreover there is, when the chamber (2) is under pressure, a virtually unexpandable but flexible limiting wall connected to the inner limiting wall along the separating slit (8) and closing the chamber (2) in the region of the frontal edges of the body. After the application of the body to the artery, the edges of the separating slit may be joined together.

Title: Low-ripple regulated current supply circuit for magnetron - derives smoother output current from rectification of negative-going half-cycles of three=phase mains voltage
Inventor: DALEY CHARLES W
IPC: H05B6/68
Filed: 1989-12-12
Abstract: Three transformers (30, 32, 34), either ferroresonant or with high stray reactance, have prim. windings connected to a three-phase supply of e.g. 208 V 60 Hz, and sec. windings via DC blocking capacitors (36, 38, 40) to half-wave voltage-doubling diode circuits (42, 50; 44, 52; 46, 54) which supply the cathode of the magnetron. The three-phase arrangement produces a load current characteristic which never falls to zero between peaks occurring at the rate of six per cycle, but maintains a positive value at all times. The redn. of ripple makes for a narrower range of magnetron output frequencies, so that it can be tuned more easily to e.g.  2.441 GHz. ADVANTAGE - Ripple is reduced considerably with more current variations per cycle in comparison with two half-cycles of conventional circuit.

Title: High-pressure separator for hydrogenation of hydrocarbon(s) - has inner wall of the insulated pressure vessel made from spiral of rectangular tube through which coolant is passed
Inventor: KLEIN WOLFDIETER
IPC: C10G1/00
Filed: 1990-02-08
Abstract: The design of a cylindrical high-pressure separator for the products of the hydrogenation of fuels is modified so  that: the internal cylindrical lining of the separator pressure vessel forms the outer wall of a cyclone separator, and the central gas/vapour outlet pipe within the cyclone separator is connected to the central outlet pipe which passes through the roof or cover of the device. The device has also the following further characteristics: the internal cylindrical wall lining is made up of a spiral of rectangular tube material, this tube spiral is connected to coolant inlet and outlet pipes which pass through the roof of the pressure vessel, and the central gas/vapour outlet is similarly formed from a spiral of rectangular tube material. USE/ADVANTAGE - This invention is used in the design of a separator for separating a gas/vapour phase from a sump product in the high-pressure hydrogenating of coal, tar or mineral oils, which is located downstream of the sump-phase reactors and consists of a cylindrical vessel with an internal insulation layer and an inner lining provided with a coolant circuit. The effectiveness of the separator is increased, and the cooling of the product vapour is improved so that greater control can be exerted over the flow pattern within the separator.
