Title: Device for sinking a terrestrial-heat-collector probe in the earth
Inventor: WALDNER ALFRED
IPC: E21B25/02
Filed: 1983-04-22
Granted: 1984-04-19
Abstract: In a device for sinking a probe serving as terrestrial-heat collector of a heat pump in the earth, it is proposed, in order to facilitate the driving, that the earth-displacement head be designed as an annular bit 4 with a central passage 5 through which a core can penetrate into the probe when it is driven into the ground, so that not all the earth has to be displaced. Furthermore, to facilitate the driving, it is also proposed that the inner tube 3 be designed with an inside diameter which corresponds to the central passage 5 but is preferably slightly larger. Furthermore, to remove the core, the inner tube 3 is also arranged in the outer tube 2 in such a way that it can be removed, so that, after it is removed, special probe parts, such as a ground-water pump or the like, can be inserted in the outer tube 2. …<IMAGE>…

Title: Method and furnace for heating slabs, ingots, billets, sheets and similar products
Inventor: PATALON HEINRICH DIPL-ING
IPC: F27B9/24
Filed: 1987-10-29
Granted: 1989-01-26
Abstract: The subject is a method and a furnace for heating slabs, ingots, billets, sheets and similar products, which are transported through the furnace chamber by a roller-hearth or roller walking-beam system. The conveying rollers 15 are arranged on both sides of the furnace chamber 10 externally on the side walls 11 of the furnace so as to be movable to and fro transversely to the conveying direction of the products to be heated and are moved through suitable wall openings 18 into the furnace chamber 10 to position underneath the products 13 to be heated, only for the short time of transporting the products to be heated. On lifting the conveying rollers 15 or lowering the support blocks 14, the conveying rollers 15 take up the products 13 to be heated, in order to move them on by rotation. Immediately after this transporting operation, the products 13 to be heated are taken off the conveying rollers 15 by opposite vertical relative movement of the support blocks 14, so that the conveying rollers 15 are able to move back into the open into a cooling rest position. This conveying-roller arrangement outside the furnace chamber causes relatively little stress and wear of the supporting-roller arrangement, as it has only short residence times in the hot furnace chamber 10, but always long cooling-off phases in between. Also, the water-cooling installation which is otherwise customary for the conveying-roller train in the furnace chamber is dispensed with. <IMAGE>

Title: Burner tube for a blue-burning oil burner
IPC: F23D11/40
Filed: 1989-03-03
Granted: 1990-10-31
Abstract: Blue-burning oil burners have a burner tube (2) with openings (3, 3') in the tube shell for the recirculation of hot burnable gases. The sum of the opening cross-sections should be as large as possible in the interests of low NOx emission. However, this worsens the cold-start properties of the burner. It is therefore proposed that some of the openings (3, 3') be closed when starting up the burner from cold. <IMAGE>

IPC: H04B1/18
Filed: 1989-04-12
Granted: 1990-10-25
Abstract: A damping circuit is described for the antenna resonance circuit (28) of a radio transmitter-receiver which in a transmitting phase transmits a time-limited high-energy interrogation pulse and in a receiving phase following the transmitting phase is ready to receive high-frequency response signals coming from a responder which transmits said response signals as reaction to the reception of the interrogation pulse. In the damping circuit (24) a damping member (R4, R5, R6) is provided which is adapted to be connected to the antenna resonance circuit and disconnected therefrom. A switching means (T4, T5) on receiving a switching voltage applies the damping member (R4, R5, R6) to the antenna resonance circuit (28). A first energy-storage element (C1) chargeable by the HF interrogation pulse serves for furnishing the switching voltage and a second energy-storage element chargeable by the HF interrogation pulse in dependence upon the time profile of the HF interrogation pulse enables the application of the switching voltage present at the first energy-storage element to the switching means (T4, T5).

Patent DE-4137978-C1 (DE)
IPC: F01L1/047
Filed: 1991-11-19
Granted: 1993-04-08
Abstract: A disassemblable camshaft for internal combustion engines comprises: a cylindrical shaft (1) which can be pushed into the bearing bores and into the cams (3) located therebetween in a single operation thus allowing small diameter one-piece bearings to be used. The cams (3) are then clamped onto the shaft to rotate therewith. The aim is to improve on conventional solutions, which use press fits between a conical sleeve on the one hand and the shaft and cam on the other to create a rotationally rigid joint, by reducing the space required for the structure and improving the ease of assembly. This is achieved by using transverse screw couplings effected by means of clamping screws under tension. The screw couplings (9) are formed in such a way that no more space is required than with conventional camshafts, assembly is simple, and can be done using standard tools.

Title: Method for accelerating the heating up of an engine, and a device for carrying out the method
Inventor: HOLLWECK JOHANNES
IPC: F02B3/06
Filed: 1993-09-13
Granted: 1994-12-08
Abstract: The invention relates to a method for accelerating the heating up of an engine and to a device for carrying out the method. In order to raise the temperature of a combustion chamber as rapidly as possible upon starting or during a transition from a low to a high load, the proposal according to the invention is that, at a low cooling-water temperature and a low charge-air temperature, the whole of the charge air should be passed via the bypass (4), that, as the charge-air temperature rises and while the cooling-water temperature is still low, part of the charge air should be passed via the bypass (4) and part via the charge-air cooler (3a) and that the entire charge air should be passed via the charge-air cooler (3a) only when the cooling-water temperature is high with the engine warmed up and a predetermined charge-air temperature is exceeded. A device for carrying out the abovementioned method consists in that the bypass flap (5) is actuated primarily by an expanding element (6b) around which the cooling water flows. The expanding element (6b) is secondarily heated by an electric heater (13) when the charge air has exceeded a predetermined temperature and the charge-air temperature detector (12) closes the circuit of the electric heater (13). It is thus possible to pass the charge air completely via the charge-air cooler (3a) only when both the charge air and the cooling water have reached a predetermined temperature. <IMAGE>

Title: Method for creating ceiling partition in room
Inventor: SMULDERS ADRIANUS HENRIKUS JOS
IPC: F24F11/00
Filed: 1995-12-21
Granted: 1997-06-24
Abstract: The method involves creating a room (1) which has a floor (3) and walls (5). On the top side the room is limited by a sheet ceiling partition (7). The sheet is fixed to the walls by means of an installation lath (9) and tension laths (11). If required, it is always possible to fit two sheets at a specific distance one above the other. Firstly, the required height of the ceiling partition is determined. Then the installation laths are fixed to the wall and the sheet with tension laths is fixed to the walls via the installation laths. Finally, the sheet is locally heated, causing it to expand. The heating is effected with e.g. a gas burner at several places covering e.g. approximately 40 per cent of the sheet. After cooling, the sheet through its shrinkage properties forms a complete and level surface.
