Title: Fabric layers with flexible coating are stitched together - to form laminated heat exchanger element
Inventor: HARTMANN HANS-WERNER
IPC: F28F3/14
Filed: 1980-10-31
Abstract: A flexible hollow-walled laminated heat exchanger element is formed of two layers of fabric coated on both sides with rubber or plastic and bonded together at regular intervals by rows of stitches, pref. of threads impregnated with rubber or like material resistant to hydrolysis. In a claimed method of making the element, two fabric webs are first coated on one face only, the webs are then sewn together with these coated faces in contact, and similar coatings are then applied to the outer faces, e.g. by dipping. The first coatings are prevented from bonding together by polymerisation or by treatment with bond-resistant material. Used in heating systems, e.g. for absorbing heat from the sun or environmental sources, or for domestic or vehicle heat exchangers or heaters. Heating fluids have no contact with unrubberised fabric threads, resulting in longer life.

Title: Fail=safe control for pneumatic brake servo - has spring coupling to hydraulic piston for return stroke
Inventor: MEISE GUNTHER ING GRAD
IPC: B60T13/565
Filed: 1980-11-08
Abstract: The servo force is generated by a pneumatic membrane servo cylinder and acts via a thrust rod onto a hydraulic piston. For the return stroke of the servo the thrust rod is linked to the piston by a spring. This limits the amount of reduced pressure in the hydraulic circuit and prevents air bubbles. The spring provides a simple controlled return force for the piston and allows the compensating valve to replace the hydraulic fluid. The air bubbles formed in conventional servos can cause damage at the flexible sealing gaskets on the piston.

Title: Method and device for the production of a two-layer Bourdon tube for pressure and temperature gauges and a Bourdon tube produced by the method
Inventor: DESOR GERHARD
IPC: B21D11/06
Filed: 1981-02-27
Abstract: The invention relates to a method and a device for the production of a two-layer Bourdon tube for pressure and temperature gauges by winding a spring blank in opposite directions from its middle onto a mandrel. To achieve the object of obtaining an exact spring geometry and of avoiding a point of friction at the intersection of the two spring halves, the invention proposes that, before winding, the spring blank is bent in a Z shape in the middle in the direction of the longest axis of its cross-section to such an extent that the transverse spacing of the mutually parallel parts of the longitudinal axes of the two spring halves corresponds to the spacing of the centre plane of the two spring layers. The spring blank is then aligned relative to the mandrel in such a way that the longitudinal axes of the spring halves are moved outside the winding zone in planes radial to the mandrel. The invention also relates to a two-layer Bourdon tube produced by this method.

Title: False floor in a building which is at risk of explosion
Inventor: PRIMUS ILLO-FRANK DIPL ING DR
IPC: E04F15/024
Filed: 1981-03-17
Abstract: In a building which is at risk of explosion, the area serving as cable basement and located beneath the false floor (10), on which the units are arranged, is used as pressure-compensation area. In order to permit the pressure surge, arising in the interior of the building in the event of an explosion, to spread from the cable basement into the switchroom located above the false floor, openings have to be provided in the false floor and these are disruptive to maintenance staff. Such openings can be dispensed with if the false floor is connected to the substructure (12) of the building by elements (11) which, when a pressure surge arises, permit the false floor to be deflected briefly out of the rest position. The deflection of the false floor can be delimited by stops (15, 17). <IMAGE>

Title: Method for measuring flow parameters which can be recorded by means of ultrasonic pulse Doppler methods, and device for carrying out this method
Inventor: HASSLER DIETER DIPL ING
IPC: G01P5/24
Filed: 1981-11-24
Abstract: In known devices for applying the volumetric flow measuring technique, the depth range (@) that can be measured without ambiguities by means of the pulse-Doppler technique is limited with respect to larger values for a given speed range and thus a prescribed lower boundary of the pulse repetition frequency. Overall, the depth range (@) is too small by a factor of two to three for practical use in cardiology. According to the invention, the Doppler signal power is measured in the inverted spectrum for the purpose of measuring the vein cross-section. When this measurement is supplemented by a speed measurement which is not spatially resolving, or not uniquely so, the boundary of the range can be extended approximately to double the value. In a device for carrying out the method according to the invention, the pulse repetition frequency (fp) and the temporal receiving gate duration (TE) are variable, and the demodulation filter (10) has an entirely specific amplitude response. <IMAGE>
