Title: Extended liq. gas phase boundary surface prodn - by feeding fluid flow in conduit over displacement body with aerofoil shape and 2nd is introduced by injector located in body at area of largest cross=section
IPC: B01F5/04
Filed: 1991-10-31
Abstract: A new procedure for producing a larger phase boundary surface in liq/gas systems has a displacement-body/channel configuration. The gaseous phase is dispersed in the liq. phase flowing over the displacement body, or vice versa, by means of an injector located in the displacement body in the area of the narrowest cross-section between the displacement body and the channel. This injector has nozzles of dia. about 0.1 mm which are approx. perpendicular to the direction of flow of the fluid in the channel. Also claimed is a device for carrying out this procedure, in which a displacement body is fixed by means of supports in a new or existing channel with a constant or slightly conical cross-section. The displacement body may have a circular or rectangular cross-section, and its cross-section increases continuously in the nozzle section up to the area of the injector so that a laminar boundary layer is formed. The contour of the diffuser section (9) has an aerofoil shape characterised by a concave curve, the max. slope of the curve at the start of the diffuser section being e.g. 6-10deg. USE/ADVANTAGE - Used for example in enriching water with O2 or for washing out dust from gases or for dispersing a liq. into a gas stream. A gaseous medium is dispersed in very fine bubbles into a flowing liq. or vice versa, by means of a displacement body which can be installed in a new or existing channel.

Filed: 1992-01-14
Abstract: The proposal is for a driver circuit with at least two output semiconductor switches (12, 14, 15, 22-24) in parallel and controllable by input control signals (I1) for switching a load. To this end, a delay device (16, 17, 25, 26) is provided to delay the input control signals (I1) of at least one of the output semiconductor switches (14, 15, 23, 24), while the input control signals (I1) are applied without a delay to at least another of the output semiconductor switches (12, 22). The driver capacity of the driver circuit is thus retained but the edge steepness is reduced especially at low loads and the quadrature-axis current component is minimised. Peak current loads are reduced or distributed in time.

Title: Single needle dialysis treatment - has control valve to controlling blood flow from patient to pump, to dialyser, to surge chamber and back again via same path, being directed by inlet and outlet valves
Inventor: SCHIMMELPFENNIG WINFRIED DR IN
IPC: A61M1/36
Filed: 1992-05-25
Abstract: The blood is controlled by a control valve (E) and is pumped from the patient, through the dialyzer and into a surge chamber and then it is returned to the patient by the same path. Thr blood pump and the dialyzer are directly coupled and the pump runs continuously. Two valves (A,B;C,D) on each of the inlet and outlet direct the flow of the blood either from the patient to the surge chamber or from the surge chamber to the patient. Integration of the full volume of the dialyzer and the tubing system is carried out before the blood returns to the patient. This is done by all four valves switching to direct the blood to the surge chamber. USE/ADVANTAGE - For dialyzers used to cure problems such as clots, thrombosis etc. Gives continuous dialysation and is nearly as effective as a two needle system.

Patent DE-4227664-A1 (DE)
Inventor: KAYS RUEDIGER DR ING
IPC: H04N7/00
Filed: 1992-08-21
Abstract: A colour television transmission system called PALplus is known in which two different signal processing methods for separating chrominance and luminance components exist within one standard, particularly the PAL standard. In this arrangement, status bits are generated in the transmitting device which control the corresponding switch-over between the signal processing methods in the decoder in the receiver. This switch-over functions as long as the incoming video signal has relatively little time base fluctuations. If the tolerance range of the time base fluctuation is exceeded, for example when the PALplus signal with the corresponding status bits is recorded on a conventional video recorder, the time base fluctuations introduced by the video recorder lead to severe picture disturbances, particularly to fluctuations in the colour saturation in the colour television receiver. To prevent the picture disturbances, an evaluating circuit which measures time base fluctuations in the incoming synchronisation signal is provided in addition to the device for evaluating the received status bits. Device, evaluating circuit and control device are used for checking whether the control signal is received and whether the time base fluctuations are within a predeterminable tolerance interval. The switching-over of the signal processing method of the decoder is carried out in dependence on this result. <IMAGE>

Title: Adjusting device, especially in intake air guides of internal combustion engines
Inventor: FLIERL RUDOLF DR
IPC: F02D9/02
Filed: 1993-02-26
Abstract: For an adjusting device, especially in intake air guides of internal combustion engines, with a mechanically and electrically controllable throttle valve, it is proposed, in order to avoid elastic intermediate elements in a drive connection, that the shaft fixed to the throttle valve be movably supported in a hollow shaft and that the said hollow shaft be mechanically and arbitrarily controllable, an electrical, controllable servomotor on the reaction moment side being rotationally fixed by way of its housing to the hollow shaft and the rotor of the servomotor driving the throttle valve shaft. In a hollow shaft coaxially enclosing the throttle valve shaft over its entire length, the said hollow shaft has slots through which the throttle valve passes, each of a width which corresponds to a predetermined swivel range of the throttle valve relative to the hollow shaft.
Patent DE-4306242-A1 (DE)
Title: Washing, hygiene and medical body massage device in baths and showers
Inventor: STAHL KARL MARTIN DIPL ING
IPC: A61H7/00
Filed: 1993-02-27
Abstract: The invention relates to a washing, hygiene and medical body massage device in baths and showers, and also includes the parts of the human back, which one cannot reach by oneself and which can be properly treated with the device. The massage is performed with a rotor massage brush on a drive unit operated via the bathing water from the shower hose. Both washing and massaging can be performed with pure water or with washing or massaging additives added to the rotor brush. In order to permit treatment of the majority of the body parts, for example of the entire back, all at once without repositioning, the entire device is connected with a lifting piston unit likewise operated via the bathing water which permits the massage brush to move upwards and downwards slowly and steadily in the region of the lifting piston unit. A device of the above type is not known, especially without having recourse to other energy sources than the bathing water. Consequently, operating the device is entirely risk-free because the structure of the brush drive escapes any overloading. With regard to the amount of bathing water, the amount of water envisaged is that produced in gas-supplied or electrical flow heaters.
