Patent DE-19743012-A1 (DE)
Title: Heating system for vehicle
Inventor: AOKI SHINJI
IPC: B60H1/03
Filed: 1997-09-29
Abstract: The heating system for the vehicle uses the engine coolant circuit to heat a heat exchanger (15) in the air inlet into the vehicle. To boost the heat output from the engine, an additional heater is fitted comprising a hydraulic unit (7) which heats the coolant through a shear effect generated by a rotor. The viscous effect heater is driven by a belt drive which also drives the hydraulic servo pump (P) and the air conditioning compressor (31). A solenoid operated clutch (6) connects the viscous heater to the belt drive. The viscous heater is activated if the steering is turned slightly when the vehicle is not moving. This enables the heater to supplement to low thermal output of the engine. If the steering turned by a larger amount the control system detects the increased in torque and gives priority to the hydraulic servo circuit by disconnecting the viscous heater and the compressor of the air conditioning system. This relieves torque on the belt drive.
Patent DE-19747237-A1 (DE)
Title: Suspension railway
Inventor: KREITZ HANJO DR
IPC: B61B3/02
Filed: 1997-10-25
Abstract: The trains have an electric drive and normally travel without drivers since distance radar on the front and rear prevents collision of wagons. The train sequence can take place as rapidly as is needed for the boarding and disembarking of passengers. The wagons can be designed to be single or double-story. At the peak periods, a stationmaster controls the trains, otherwise a central control room via video. The trains have light panels and loudspeakers which indicate the next stop.

Title: Cover sealing to vessel e.g. glass, mug, can or carton containing carbonated drink
Inventor: KRUEGER BURKHARD
IPC: B65D47/24
Filed: 1997-12-20
Abstract: A novel cover (2) for a drinking vessel (4) has spillage protection. There is an opening (10), allowing fluid to be drawn from the vessel, closed by a valve plug (14), held against a valve seat (20) in the opening, pressed from within. The valve plug has a projection (16), reaching through the opening to the exterior. Inward pressure on this external tip (18) will open the valve, allowing the drink to be consumed. Preferably on pressing-in the valve plug, an annular gap (12) is cleared between the projection and the edge of the opening. The opening is formed in a bush (8) serving as the mouthpiece, and a suction tube (22) reaches down from the valve to the base of the vessel. Closure is effected by a spring (36), especially of spiral form. The valve housing (24) is removable from the bush, and has a cavity with upper and lower openings, which includes the valve plug. In forming the annulus, the housing decreases in diameter, upwardly. The spring seats on a shoulder (40), to press the plug against the valve seat (20). The shoulder is formed in a removable shell (42), inserted into the lower housing of the valve. The shell includes a central hole in communication with the vessel interior, via the suction tube. The valve housing has cleaning openings (34). The valve components are generally rotationally-symmetrical.

IPC: F25J1/02
Filed: 1998-05-12
Abstract: The pressurized stream is divided, forming a first side stream (2) cooled by heat exchange (E1) with a first process stream. It is let down (V1) to medium pressure. The temperature of the second side stream (4) is reduced by a cooling circuit (E2, E3). This stream is let down in a turbine (X1) to medium pressure. Gas fractions arising from the expansions are separated (D1), to be heated by the first side stream (2). Liquid (9) withdrawn from the separator (D1) forms the product.  An Independent claim is included for the corresponding plant. Preferred Features: The initial pressure is 60-150 bar. In a similar process, the cooled side stream is expanded to a pressure at which 90%, preferably at least 93%, of the side streams condenses. The first side stream amounts to 20%-40% and the second side stream (4) to 80%-60%, of the input flowrate. The expander (X1) precedes the separator (D2). An expansion valve (V5) precedes the separator (D2). Separated fluid (12') is mixed into the gas fraction from the separator (D1) and/or supplied to the separator (D1). Fluid separated (D2), and supplied to the other separator (D1) is super-cooled before supply to the separator (D1).

Either the input signal or the phase-shifted signal are additionally inverted in an inverter (5). The polarization of the direct part signal, resulting from the mean value determination, is adjusted in dependence of the inverter position and its link to the R or S flip-flop input.

IPC: F16L21/03
Filed: 1998-06-17
Abstract: The invention relates to a sleeve joint, comprising an expanded connecting sleeve (3, 3') which is configured for receiving an inserted pipe end (1). Starting from a particular pipe diameter (4), the enlargement runs cylindrically parallel to a straight wall section of the inserted pipe end (1) in a first section (5). In a second section (7) which is bent outwards, it forms a ring-shaped receiving chamber (8) together with the inserted pipe end (1). The inventive sleeve joint also comprises a ring-shaped sealing element (9) which grips the free end (13) of the sleeve (3, 3') axially, from behind with a peripheral projection (10), said projection projecting radially outwards, and which protrudes into the receiving chamber (8) with an essentially cylindrical ring body (14). The ring body is configured in such a way that it rests in the receiving chamber (8) with prestress and is also supported on the inserted pipe end (1) and on the sleeve wall of the receiving chamber (8). The inventive sleeve joint is both mechanically stable and reliably vacuum tight since the cylindrical ring body (14) extends into the first section (5) of the sleeve (3, 3') with material thickness which is at least equal to the space between the wall sections (6) which run parallel to each other there.
