Title: Spectrophotometric monitoring of oxidative metabolism - detects and measures intensity of radiation emerging at point spaced from entry point of near IR
Inventor: JOEBSIS FRANS FREDERIK
IPC: A61B5/00
Filed: 1980-05-20
Abstract: The spectrophotometric appts. monitors metabolism in a body organ using measuring and reference wavelengths within the near infrared region, i.e., 700-1300 nm. Monitoring of oxidative metabolism is accomplished by monitoring oxygen sufficiency in an organ, e.g., the brain. The spectrophotometric measurements are made by transmitting near-infrared radiation in at least two different and periodically recurring wavelengths to the test organ, in situ, and detecting and measuring the radiation intensity which emerges at a point spaced from the point of light entry for assessment of biochemical reaction utilising the Beer-Lambert Law. The light source and light detector are spaced apart on the same side of the head. The method provides for detecting light reflected back to the light source location and using this as a correction for skin blood volume changes.

Title: Gear tooth grinder adjustment - has tool carrier axially movable on roller-supported cylinder with scale viewed on radius through one roller centre
Inventor: ULRICH HANS-JOACHIM DIPL ING
IPC: B23F5/02
Filed: 1980-11-21
Abstract: The arrangement is intended for accurately adjusting the angular position of the rotatable cylinder (1.1) on which the tool carrier of a tooth flank grinding machine is axially movable. The gear wheel being machined is rotated during grinding and indexed around to grind successive tool flanks. The cylinder is rotatably supported by two rollers (4) engaging the inner cylinder surface (1), whilst its outer surface (2) carries a scale (3) which can be read via a viewer (5) fixed to the frame of the grinding machine. The optical axis (g) of the viewer coincides with the radius from the rotational centre (M) of the cylinder through the centre of one of the rollers, thus eliminating angular errors due to inaccuracies of the rollers or their bearings.
Patent DE-3048542-A1 (DE)
Title: Artificial lung modules - membrane is treated with metallic salt solution and gaseous precipitator when already inside module
Inventor: HENNE WERNER DIPL CHEM DR
IPC: C08J5/18
Filed: 1980-12-22
Abstract: Catalytic membranes for artificial (human) organs, in the form of plastic film tubing, flat film or hollow filaments, and containing metals or metallic compounds, are produced by introducing a metallic salt solution into the plastic membrain and blowing through a gaseous precipitating agent. The artificial organ module already contains the membrane when treated with the solution and gas. Suitable for e.g. artificial lungs/catalytic membrane modules without the usual problems of easy physical damage. Artificial organs e.g. kidneys or blood oxygenators are normally produced with the membranes in a special module which has inlets/outlets for the blood and cleansing liquid, the module being changed after treating the patient. By making the complete module and metallising later no special storage is necessary; oxygenators requiring large surface area membranes can be produced from several modules in series or parallel. When the metallic salt solution and then gaseous precipitator are fed successively through the space for the blood flow, the membrane is automatically being tested for its sealing and leak-proof properties. This is particularly important in oxygenator modules using H2O2 which would be dangerous if it passed through.

Title: X-ray diagnostic device for examining a number of layers of an object to be recorded
Inventor: KOOB LOTHAR DIPL ING
IPC: H05G1/26
Filed: 1981-03-26
Abstract: The invention relates to an X-ray diagnostic device having an X-ray tube for emitting beams onto a common ray detector (7) from different directions, which beams pass through a number of layers of a patient (1), and having a computer (15), connected to the ray detector (7), for reconstructing images of the transilluminated layers from the detector output signals. The anode (2) of the X-ray tube exhibits a number of tracks (3 to 6) from which in each case one X-ray beam emanates. Each X-ray beam is periodically interrupted in a time-coded manner and measuring electronics (8 to 15; 17 to 22) are connected to the detector (7) which isolate the output signals of the detector (7) allocated to the individual X-ray beams. <IMAGE>
Patent DE-3116881-A1 (DE)
Title: Dynamic door closer
Inventor: DUENNE HORST
IPC: E05F1/06
Filed: 1981-04-28
Abstract: The invention relates to a new construction of the hinge point (bottom) of a door. The object on which the invention is based is, therefore, to bring about the self-closing effect by means of a suitable, simple and invisible construction. This object is achieved, according to the invention, in that the original lower hinge point A is displaced towards B (see the accompanying annexe). As a result of this displacement of the lower hinge point (the upper hinge point of the door remains unchanged), a hinge axis oscillating in space is obtained when the door is opened. As a result of this eccentricity of the two door hinges, with an increasing degree of opening of the door the latter is raised and, as a result of the dead weight, an energy in its position is generated at its centre of gravity. Moreover, by the new arrangement of the lower hinge point, a torque is generated via the lever obtained on the lower hinge point. These two facts bring about an automatic closing, thus preventing temperature equalisation between two rooms (energy saving), an aesthetic value as a result of a scarcely visible variation in the lower suspension, no obstacle for floor coverings as a result of the raised door, and the possibility of installation in new and existing doors. <IMAGE>
Patent DE-3119635-A1 (DE)
Title: "Process and appliance for preparing silver powder"
Inventor: STEGEMANN HERBERT
IPC: C25C5/02
Filed: 1981-05-16
Abstract: The preparation of silver powder preferably employs electrolytic processes, in which the silver crystals are removed from the cathode by means of scrapers. Apart from the fines arising in the process, the shape of the powder produced is not optimally suitable for all application purposes. A better powder with uniform particle size and without the formation of agglomerates is obtained if the deposition takes place on a disc-shaped cathode which rotates at high speed about the disc axis and is provided with a smooth surface and a sharp perimeter edge, and the electrolyte contains a surfactant.
Patent DE-3119805-A1 (DE)
Title: Horizontal diaphragm pump with hydraulically positively driven, spring-loaded diaphragm valves
Inventor: KOWALZIK HARTMUT
IPC: F04B7/00
Filed: 1981-05-19
Abstract: Since diaphragm pumps of conventional design, whether driven mechanically or hydraulically, are suitable only for delivering clean liquids, as they are equipped with globe valves for controlling the intake and discharge stream, the horizontal diaphragm pump having hydraulically positively driven diaphragm valves has been conceived for the delivery of contaminated liquids, muds and pastes. In the essential part of the invention - the diaphragm valves - the throughflow ducts in the valve body are sealed by an elastic diaphragm which is loaded, on its rear side, by a pressurised hydraulic chamber, so that any contaminants carried along with the pumped liquid can be enclosed by the elastic diaphragm, the diaphragm valves therefore remain pressure-tight in all cases. The pressure present in the hydraulic chamber is generated via an elastic diaphragm which seals the hydraulic chamber at its underside, by a spring of arbitrary design acting on such a diaphragm. The tension valve spring is pushed back, in order to open the diaphragm valve, by an eccentric cam fixed on the pump shaft, so that the valve is open over an angle of rotation of approximately 160 DEG .

Title: Rotor blade design for high-speed rotors
Inventor: STAMPA ULRICH
IPC: F03D7/02
Filed: 1981-07-07
Abstract: In a rotor blade design the blade tip area is designed as a separate rotor blade part and connected to the rotor blade by way of a pivot axis so that the rotor blade part can be adjusted by wind forces. In this an adjusting movement is limited by an elastic element between rotor blade part and rotor blade. In addition the rotor blade part is designed so that in cross-section the centre of gravity of the profile, the shear centre of the supporting connection and the centre of pressure are arranged one after another starting from the profile leading edge. This design permits automatic damping for differing loads due to an automatic adjustment of the blade angle with a variation of the angle of flow. <IMAGE>

Title: Pressure-cooker handle release
Inventor: LAUBNER JOACHIM
IPC: A47J27/092
Filed: 1981-08-31
Abstract: The invention relates to a pressure-cooker having a lid which can be locked on the cooker by turning it, a handle on the lid and a handle on the cooker being closely adjacent in the locking position. Devices are known with handles which lie one above the other over the entire length and with approximately horizontal joint in the locking position. These require awkward handling, especially if both handles have to be gripped simultaneously with one hand. The locking position which is required for safety reasons is visually not precisely recognisable. The object of the invention is a design in which the cooker and the lid can be moved without difficulty and without special attention from the open position into the locking position and vice versa. According to the invention, the object is achieved in that the cooker handle and the lid handle lie laterally against one another with an essentially vertical joint at least in their pot-shaped end region in the locking position. The cooker handle and lid handle are thus mainly pushed laterally against one another. The movement is visually clearly recognisable. There is no scissor movement with the risk of trapping the fingers. The handles may be designed to be tapered in the end region and thus easily grippable.
Patent DE-3136355-A1 (DE)
Title: Microcomputer system
Inventor: PETERSEN HANS-JOACHIM ING GRAD
IPC: G06F13/42
Filed: 1981-09-14
Abstract: The system comprises a number of microcomputers (MC1, MC3) and a central control device (ZSE) which manages the use of a bus by the microcomputers. For the purpose of allocating the use of the bus, the requesting microcomputers (MC1) occupy request lines (S1) which are interrogated cyclically by the central control device. The latter acknowledges a request picked up and thereby prompts the requesting microcomputer (MC1) to output the respective destination address onto the data bus (DB). The microcomputer (MC3) thereby addressed informs the central control device whether it is capable of accepting data. Only if this is the case does the central control device release the transfer of data. The cyclic interrogation of the request lines is subsequently continued. The transmission speed is independent of the processing speed of the microcomputers in the system. <IMAGE>

Title: High-pressure heat pump
Inventor: FLOEGEL PETER
IPC: F24J2/00
Filed: 1982-04-17
Abstract: The invention is designated a "high-pressure heat pump". It is to be assigned to the technical field of heating technology. The invention relates to an improvement of the degree of efficiency in the raising of temperatures of heating media. Conventional compression heat pumps are afflicted with an array of energy losses as a result of evaporation, liquefaction, flow as well as overheating of the working medium in the compressor. The high-pressure heat pump solves the problem by working with a high-pressure medium, e.g. silicone oil, making use of the throttle effect without changing the state of aggregation. It consists of pressure pipes with heating pipes arranged concentrically on the inside. The high-pressure medium is situated between the pipes. The casing surfaces of the pressure pipes are acted upon by the heat source (outside air, groundwater etc.). The heating pipes carry off the heat quantities raised to the higher temperature level. The main application possibility of the invention is the field of room heating.
