Title: Hot-water-supply system
Inventor: VILIMEK HELMUT
IPC: F24D19/10
Filed: 1993-12-15
Abstract: The circulation regulator (11) between the exchanger outlet and the tank requires no external power supply, Its free cross-section increases with the water temperature above its rated setting. It can consist of a thermostat valve containing expanding material, and can be arranged to shut the flow right off below its rated temperature.

IPC: H01L29/745
Filed: 1994-02-01
Abstract: The invention pertains to a MOS-gate switched power semiconductor component with a semiconductor body that has a number of unit cells arranged side-by-side and switched in parallel and consisting of a p-emitter zone adjacent to the anode, an adjoining, weakly doped n-base zone, then a p-base zone and an adjoining n-emitter zone. Incorporated in the n-emitter zone of the unit cells are pairs of p<+> zones (5a, 5b) which, together with the n zone between them and an insulated gate situated above, form a lateral p-channel MOSFET (M1). The n-emitter zone (4) is equipped with a floating cathode contact (K') which at the same time constitutes the electrode of the p<+> region serving as source. The p<+> region serving as drain is connected to an external cathode (K), which has no contact with the n-emitter zone. Another MOSFET is formed by the surface region of the p-base zone (3) and the intervening region of the n-emitter zone (4b) together with an insulating gate. The gate electrode of the second MOSFET is formed as part of the cathode metalization. There is a defined ratio of the breakdown voltages of the MOSFETs.

Abstract: A roof substructure for roofs decked with roof decking boards is made up, in the case of a couple roof to be insulated, of an exposed panel work (4) attached to the rafters (6); a film-type vapour barrier (8) laid on the exposed panel work (4); an insulating layer (10) based on mineral wool which is laid on the vapour barrier (8); and a film (24) which is water repellent and is open to diffusion which is laid on the insulating layer (10) and covers the latter. In this case, the insulating layer (10) is made up of at least two types of strips (18, 22) which are laid alternately individually and without gaps parallel to an edge of the roof, that is to say in a steep-pitched couple roof to the ridge (16) and to the eaves (12), the one type of strip (18) serving to absorb the roof load, introduced via base battens (20), of the roof parts located above the insulating layer (10), and having a far higher compression strength in relation to the other type of strip (22), serving purely insulating purposes, and being of a many times narrower design compared to the other type of strip (22), serving insulating purposes. In this case, the strips (18) for absorbing the load have a compression strength of at least 50 kN/m<2> and consist, like the strips (22) serving purely insulating purposes, solely of bonded mineral wool. <IMAGE>

IPC: B29C65/02
Filed: 1994-08-13
Abstract: For welding tube socket joints in thermoplastic tubing, where the straight end of one tube is inserted into the socket end of the next tube section, heat is applied to melt the thermoplastic material together with a pressure to bond the sections together. The pressure is set to give a structured joint pressure, where there is a defined pressing action on the outer circumference of the inserted tube end against the inner circumference of the surrounding socket of the other tube end, before the welding action develops. The pressure is continued until the material has cooled after the welding stage.

Title: Evaluating fill-level of container, using mechanical vibration system with piezoelectric elements
Inventor: BENZ KARL
IPC: G01F23/296
Filed: 1994-08-18
Abstract: The filling level evaluation involves a receiver converter which receives the vibrations of the mechanical vibration system and converts this into an electric output signal. At least two identical stacks (14,15) are prepared with piezo-electric elements (16). A tension bolt (5) is coupled with its end lying opposite the diaphragm (4) at the top side of the stacks and decouples the underside of the stacks from the diaphragm. Oscillating rods (2,3) are excited by the application of an AC voltage at the excitation converter of the two stacks. The individual output signals of the receiver converter are combined. With an in-phase vibration of the oscillating rods, the complete output signal assumes approximately a zero value, and with an antiphase vibration of the oscillating rods, assumes a value, differing from zero.

Patent DE-4434978-A1 (DE)
Inventor: BLECKMANN HANS-W
IPC: G01B7/14
Filed: 1994-09-30
Abstract: In so-called active sensors that transmit to an electronic regulator (7) an output signal (IS) whose amplitude does not depend from the speed of the encoder nor from the distance between sensor (6) and encoder (5), determining whether the length (d) of the distance set between the sensor (6) and encoder (5) is sufficiently small to ensure that the input signal generated in the sensor (6) has a sufficient amplitude even when the distance is dynamically increased represents a problem, since said length (d) may not be determined from the output signal (IS). If the input signal induced by the encoder (5) in the sensor (6) is too low, a sensor-inherent hysteresis threshold (V1) is not exceeded and no output signal (IS) is generated. In order to prevent the sensor (6) from being unintentionally driven to the limits of the maximum admissible distance between sensor and encoder, the sensor-inherent hysteresis threshold (V1) is set at a higher value (V2) for test purposes. If a sufficient input signal is generated even at said higher hysteresis (V2), it may be supposed that the sensor is correctly mounted.
