Title: Rotary pumps
Inventor: JENSEN NILS DUE
IPC: F04D15/00
Filed: 1983-07-05
Abstract: In a pumping set comprising a rotary pump driven by an electric motor the speed is controlled as a function of selected operating parameters in steps within a characteristic field, the limits of which are determined by two modulating graphs H(Q) for the maximum and minimum speeds and by the co-ordinates of delivery head H and delivery flow Q. A particular partial span is in each case determined on the modulating graphs for constant speeds. A speed switching action is initiated upon reaching the operating parameters of the set representative for the terminal values of the partial spans, the speed being lowered if the one terminal value is reached on one partial span with the greater delivery head H and the lesser delivery flow Q, and raised if the other terminal value on the partial span in question is obtained with the lesser delivery head H and the greater delivery flow Q. The pumping set may be employed in a hot water and central-heating plant.

Title: Method and device for examining the state of a cardiovascular system
Inventor: VINOGRADOV ALEXEI VIKTOROVICH
IPC: A61B5/022
Filed: 1984-04-13
Abstract: The method for the examination of the state of a cardiovascular system provides for the determination of quantitative values, which characterize a blood supply occurring in each of examined parts of a body, and which correspond to the sum of absolute values of areas, enclosed by all positive and negative half-cycles formed by the first-order time derivative of a pulsation pressure, which oscillates inside a blood vessel of the examined part of the body. Sums and ratios of said values are computed for sampling populations of the body parts and are compared with the average statistical ranges of the appropriate values, sums and ratios, which were found as typical for both healthy organisms and for organisms having known pathological deviations. Results obtained thereby are interpreted for diagnosing the state of the cardiovascular system. The device comprises channels (5) provided for the measurement of the values characterizing the blood supply, the number of which channels corresponds to the number of the examined parts of the body. Each of the channels comprises an occlusion cuff (2) by which a pressure on the examined body part is exerted through a pneumatic splitter (7) from a source (1) of the variating pressure, a tachooscillation transducer (3) separating the first-order time derivative of the pulsation pressure applied upon the cuff (2), a unit (6) effecting the measurements of the quantitative values of the blood supply and a recording unit (4). The computation of the sums and of the ratios of the quantitative values characterizing the blood supply occuring in the sampling populations of the body parts, as well as their comparison with said average statical ranges is performed by a computing unit (29).

Title: Mounting and adjusting beaters of a hammer mill
Inventor: SAUERMANN WERNER
IPC: B02C13/28
Filed: 1985-02-28
Abstract: Each beater 3 has a slot in the form of a straight portion connecting two mounting bores having diameter 10, a rotor shaft (2, Fig. 4 not shown) being located in a selectable one of the bores. The width of the straight portion of the slot is smaller than the diameter of each bore but greater than the radius of the shaft, one side of the straight portion contacting the bores tangentially. The shaft is provided with milled grooves (6), the depth of which is such to give a shaft width equal to the width of the straight portion of the slot so that when the slot is aligned, by rotation of the respective beater, with one of the grooves the beater can be slid across the shaft to relocate the shaft in the other one of the bores. The axial position of the beaters on the shaft is determined by spacer sleeves (4). <IMAGE>

Title: Gas turbine engine valve control system
Inventor: CURETON JOHN EDWARD
IPC: F02C9/52
Filed: 1985-03-05
Abstract: A control apparatus (32) for the bleed valve (30) of a gas turbine engine compressor (14) enables the engine to be operated with a low risk of compressor surge or stall, particularly on emergency shut down. The control apparatus (32) includes a control valve (34) operated by a ram (56), a fast response valve (36) and an early opening valve (38), the ram also operating a row of inlet guide vanes (120) of the compressor. When the ram (56) operates the valve (34), high pressure air from the compressor is fed to the bleed valve to open the valve at a slow response rate. The valves (36, 38) are responsive to fuel pressure to improve the response rate of the bleed valve so that on rapid shut down of the gas turbine, the decrease in fuel pressure is sensed by the valves (36, 38) to rapidly open the bleed valve. <IMAGE>

A directional transmitting and receiving coil construction is consequently obtained with no coupling between the transmitting coil and the receiving coil (30). The object to be identified may be a working tool, eg a cutting tool for a production machine, the transponder being contained in a groove in the tool. The transponder may include tuned circuits and encoded information as to tool wear or service life. <IMAGE>

Patent GB-2182876-A (GB)
Title: Alloy strip production
Inventor: CANTOR DR BRIAN
IPC: B22D11/06
Filed: 1986-10-28
Abstract: Binary alloys in which the component elements do not exhibit complete mutual solubility in the liquid form (e.g. Al-Pb) are made into strip. A particular alloy is melted to a temperature where a single liquid phase only is present and rapidly solidified at a rate greater than 10<4> DEG K/s (e.g. 10<5> - 10<6> DEG K/s) to give the strip. For example, a jet of the molten liquid may be caused to impinge upon a cool moving surface (e.g. a rotating wheel) so that solidified alloy in the form of strip is ejected therefrom. The strip has a fine, uniform dispersion of one component of the alloy in the other which, in the case of Al-Pb, may make it useful as a bearing material. In an example, the particle size range quoted is 0.15nm to 8nm. Other binary alloys to which the invention may be applied are Cu-Pb and Cu-In.
