Patent DE-4020587-A1 (DE)
Inventor: GROSS RUDOLF
IPC: F01K9/00
Filed: 1990-06-28
Abstract: 1. Low-pressure steam condenser system for condensing the steam leakage from shaft seals (2) of a steam turbine installation (1) having heat exchanger surfaces (77) cooled by the condensate of the condenser (60) of the steam turbine installation (1), the low-pressure steam condenser (70) being integrated into the condensate induction line (77) of the condenser (60). This system allows the low-pressure steam condenser (70) to be designed as a pressure-free heat exchanger. Particularly advantageous is an arrangement of said heat exchanger inside the condensate collecting space (61) underneath the condensate level (63) in the condenser (60). In this arrangement, the low-pressure steam condenser (70) can form an extension of the condensate induction line (75) within which there are arranged heat exchanger pipes (77), around which the condensate can flow, in which the low-pressure steam condenses. It is advantageous for the condensate to flow in on both sides of the low-pressure steam condenser (70) from which the condensate enters approximately in the centre into the condensate induction line (77). The arrangement is particularly space-saving and cost-effective because of the pressure-free design of the low-pressure steam condenser. <IMAGE>

Title: Sepg. plastic coated metal - by passing strips of combination material over induction heater and diverting sepd. constituents into different containers
Inventor: ZINK WALTER
IPC: B26F3/06
Filed: 1990-07-17
Abstract: Metal-plastics composites, and partic. flat strips of metal with a plastic covering, are sepd. into their constituents by subjecting them to a temp. which affects the one constituent more than the other. Specifically, two endless belts (11, 12) move together for a distance, forming an entry end (13) and outlet end (14) to the narrow gap between them, both passing round one particular guide roller (15). An inclined chute (16) guides strips of the combination material into this entry (13) as shown by the arrow (17). The strips, which are plastic-coated metal, are moved past an induction heater (18) which causes the plastic layer to separate from the metal. The plastic material remains on the lower belt (12) at the outlet end (14) and drops off (20) below, whilst the metal is carried further and is sent into a different holder (21) by the influence of a magnet (23). This separation is also aided by the blade (24). ADVANTAGE - The method is cheap and simple.

Title: Method of producing fibreboard from waste products - involves using chopping device with hopper and upper and lower endless belt presses
Inventor: SCHIKARSKI HORST
IPC: B27N3/24
Filed: 1990-11-28
Abstract: A method of producing fibreboard uses fibre cuttings with a resin bonding agent which are poured between two parallel press machines and hardened by a heat process. The raw material is composed of waste fibre chopped up and soaked in resin, and is fed from a hopper (4) on to an underlay (9) to form a dense mat (10). The mat (10) is then passed between an upper (6) and a lower (5) endless steel band press. Before pressing the mat (10) is wrapped in resin soaked fibrous bands which become, after pressing, the face of the fibreboard. USE/ADVANTAGE - Re-uses waste material.

Title: Deep depletion detector diode with simplified operating requirements - has high resistivity bulk with implanted regions and features backside etched depression allowing low voltage operation and direct coupling to emitter
Inventor: WELSER WOLFGANG
IPC: H01L31/0352
Filed: 1991-01-26
Abstract: A detector diode for operation in full depletion for use as a space charge region consists of a monolithic structure in a single crystalline material, such as (100) high ohmic Si. The device is a diode in which by micromechanical etching a depression has been formed in the surface opposite the surface to which the connections are made.

The depression formed into the backside of the detector can be placed directly on or over the emission source or scintillator. USE/ADVANTAGE - The "drift chamber" diode can be operated at lower bias levels due to the presence of the depression. By having both contacts on the top side the diode can be easier connected to other equipment. The diode can be placed directly over the source of the radiation or the scintillator. The mfg. process requires only standard process technology. The device is used as a detector of nuclear particle and photon emission.

The appts. can be incorporated in the collection vessel for the used glass. A hard pin can be inserted into the hammer head (6). ADVANTAGE - The appts. breaks up the glass material taken from a collection container, simply and without hazard.

Title: Ship's path controller - compares desired and actual courses while taking account of sideslip angle to cope with high wind and tide conditions
Inventor: LAABS HEINZ DIPL ING
IPC: G05D1/02
Filed: 1991-03-28
Abstract: A ship's track controller computes the ship's deviation from its desired track using the measured ship's position and feeds it to a deviation controller. The output of the controller is compared with an actual course. A further signal is fed to the compaison point (22) of the actual and desired courses. This signal is related to the ship's sideslip angle beta = arc tan (v/u) where v and u are the transverse and longitudinal speeds of the ship respectively. USE/ADVANTAGE - Adequate track control accuracy even for low ship speeds in presence of high wind and tide effects and without loss of control stability.

Title: Torque measurer for rotatable deformation device - uses ring picking up amplified axial movement of pliably linked levers distributed over circumference
Inventor: TIMTNER KARLHEINZ DR ING
IPC: G01L3/14
Filed: 1991-03-28
Abstract: The deformation device (50) hhas axially and/or radially neighbouring sections. They pliably rotate relative to each other when torque is transmitted. This moment is converted into amplified axial movement by pivoted levers (4a) applied to the circumference. This axial movement is used as a measure for the transmitted torque. The levers are forked with their prongs (40a,41a) touching one or the other of the sections. The fork handle (43a) is linked to the pick-up ring (5). The deformation device, levers and pick-up ring are stamped metal parts. At least one lever is additionally stamped or embossed and joined to the sections and ring by welding or soldering.

Title: Clamping ring for elastomeric sealing ring in pipe - consists of expander ring with overlapping ends
Inventor: ARLT GERHARD
IPC: F16L49/02
Filed: 1991-05-04
Abstract: The clamping ring for fixing an elastomeric sealing ring in a pipe sleeve consists of a divided expander ring (1), the ends (2,2') of which overlap (5) when in position.

The two overlapping expander-ring ends (2,2') interlock on their radial outer periphery or abut leaving a radially outer gap between their ends, bridged by a thin-walled, guide-sleeve. A connecting-wire or strip is inserted into the pipe's holloe duct. ADVANTAGE - The sealing inserted between the sleeve and the elastomeric sealing ring it contains requires only relatively low radial forces to be applied to the clamping ring for the sealing ring to be deformed near the clamping ring.
