Title: Body cavity inflation system with microprocessor control of pressure - uses single or multiple needle access for inflation and deflation for diagnostic and/or operative purposes
Inventor: FARIN GUENTER
IPC: A61M13/00
Filed: 1992-06-17
Abstract: The inflation system (1) controls the gas supply from a high pressure source (3) via a control valve (4) through piping to inflation needle (7). The gas discharge from the body cavity is via a control valve (8) to a vacuum or low pressure reservoir (10). A processor unit with associated software sets an upper limit for inflation pressure (Pmax1) and a lower limit (Pmax2). The control valves (4,8) are controlled so that, when the measured pressure exceeds the upper limit, the low pressure source is connected. When the pressure is below the lower limit, the high pressure source is connected. The internal cavity pressure is measured by a separate needle probe, or the control valves are both closed to allow pressure measurement by the single needle (7). USE/ADVANTAGE - Internal organ examination, surgery etc. ('keyhole' surgery). Gas pressure in body cavity does not exceed set stipulated or max. value even if cavity is subjected to pressure and/or additional gas is introduced from another source. Conversely, stipulated value does not fall too low if intensive loss of gas occurs.

Title: Spray nozzle device for a window washer system
Inventor: EPPLE ANTON
IPC: B60S1/52
Filed: 1993-02-04
Abstract: To prevent freezing up in the spray nozzle region it is known to arrange an individual heating wire in the supply channel itself, in direct contact with the liquid to be supplied, and protruding as far as a nozzle body. The novel spray nozzle device provides a two-part design of the nozzle body (1), a lower part (3) containing the connection for the liquid-supply line (11) and at least one nozzle head (4) and the interconnecting channel (8') for the liquid, and a covering upper part (2) securable to the lower part (3). In this case, the heating cable is guided separately from the channel for the liquid in a loop (9) from the end of the liquid-supply line (11) in or on the lower part (3) as far as the nozzle head (4) and back again to the end of the liquid-supply line. This makes it possible for a single heating cable to heat both the nozzle body up to the nozzle-outlet region and also the liquid-supply line. Use for the window washer system of a windscreen or rear window of a motor vehicle. <IMAGE>

Title: Car seat with side cushions that have two alternative positions - has side cushions normally flat but which tilt upwards in side-impact crash to protect passenger from door
Inventor: SINNHUBER RUPRECHT DIPL ING
IPC: B60N2/90
Filed: 1993-02-20
Abstract: The patent concerns a seat in a car with movable side cushions. One side cushion is near the door, the other near the transmission tunnel.

Title: Method for the storage and reproduction of an audio signal
Inventor: KAADEN JUERGEN DIPL ING
IPC: G11C7/16
Filed: 1993-03-12
Abstract: In the case of an audio signal it is known to interrupt the storage during a speech pause and to store only an identifying signal for the duration of the speech pause, by means of which, during reproduction, the sound channel is muted for the duration of the speech pause. The reproduction of such an audio signal with muted speech pauses can operate subjectively in an unpleasant manner. It is the object to reduce such a subjectively unpleasant impression in the event of the reproduction of speech. According to the invention, during the reproduction, a digital filling signal representing a background noise is inserted into the signal during the speech pauses. [lacuna](Application) in particular in the storage of speech signals using computers and PCs in the field of multimedia. <IMAGE>
