Title: Element for damping pressure oscillations in hydraulic systems
Inventor: KEMMNER ULRICH DIPL ING
IPC: F16L55/04
Filed: 1981-11-24
Abstract: An element is proposed which serves to damp pressure oscillations in hydraulic systems, especially in a system for delivering fuel which is fed from a storage tank to an internal combustion engine. The damping element through which the fuel flows and which elastically increases in volume under the effect of each pressure oscillation is arranged in a feedline which leads from a displacement pump to the internal combustion engine. The inflow and outflow apertures in the damping element are so arranged that the direction of flow of the fuel in the damping element is deflected. The build-up of fluid associated therewith effects a particularly effective damping of the pressure oscillations in the hydraulic system. <IMAGE>

Title: Apparatus for holding a record firmly in place on an underlay by suction
Inventor: RAEKE JOCHEN
IPC: G11B17/32
Filed: 1981-11-26
Abstract: In order to achieve that a record (12) rests flatly on the turntable during playing, an underlay (11) having a sealing lip (13) running around the outside is fastened on the turntable (10). Once a record (12) has been placed on the underlay (11), a suction device comprising a bellows (20) is put onto the pin (15) of the record player. By pressing the bellows (20) down, air is expelled from the latter. When the bellows is subsequently released, air from the area between the underlay (11) and the record (12) is sucked away between the pin (15) and the record (12), so that the record (12) rests firmly on the flat underlay (11). The suction device does not require any external energy and is able to maintain the suction force for the playing time of the record. <IMAGE>

Title: Mixture-compressing, spark ignition internal combustion engine, especially for motor vehicles
Inventor: HAPPEL ROBERT
IPC: F02B1/04
Filed: 1982-03-30
Abstract: A mixture-compressing, spark ignition internal combustion engine, especially for motor vehicles, comprises a main combustion chamber and a prechamber, in which a spark plug and a prechamber injection nozzle are arranged, and an intake pipe injection nozzle. Fuel from an air-measuring, driveless injection system with continuous fuel feed is fed to the intake pipe injection nozzle, which system comprises a fuel distributor, having a control piston and a leakage line, and a mixture regulator, a sealing element sealing the fuel-washed part of the control piston off from the mixture regulator being assigned to the control piston. In order to completely prevent the feeding of leakage fuel into the mixture regulator in the area of the control piston of the distributor, the sealing element seals the fuel-washed part of the control piston off from the mixture regulator in all positions of the control piston.
Patent DE-3214048-A1 (DE)
Title: Intake pipe arrangement for internal combustion engines, especially of motor vehicles
Inventor: JURKOVIC TADIJA DIPL ING
IPC: F02M35/10
Filed: 1982-04-16
Abstract: An intake pipe arrangement for internal combustion engines, especially of motor vehicles, has a distributor chamber open at the top, on the connecting sleeve of which a downdraught carburettor is flange-mounted, and intake pipe arms, lying approximately in a horizontal plane and running out from the distributor chamber like a fan, which arms lead to the individual cylinders of the internal combustion engine in such a way that the air-fuel mixture flowing vertically downwards from the carburettor must be deflected by 90 DEG or essentially by 90 DEG  in the distributor chamber in order to pass into the intake pipe arms. The rear wall of the distributor chamber connection sleeve lying counter to the connections of the intake pipe arms is formed with an inclined surface in such a way that the wall incline projects into the downwards-directed flow of fuel-air mixture. An intake pipe arrangement designed in this way has the advantage that partial recondensation of the fuel-air mixture prepared in the carburettor and hence the production of leakage fuel is prevented at no great expense. This leads to a reduction in the fuel consumption, to an improvement of the mixture distribution and thereby to a considerable improvement in the efficiency of the engine. By means of the above-mentioned measures a significant improvement in the functioning of the engine is also achieved in the critical cold phase and at low speeds.

Filed: 1982-04-28
Abstract: The invention relates to a positive displacement machine for compressible and incompressible media having at least one displacing chamber arranged in a fixed housing and having a displacing body assigned to each displacing chamber and held on an eccentrically drivable disc-shaped rotor, the rotor being guided in such a way relative to the housing that, during operation, each point of the displacing body executes a motion lying essentially on a circular path, and the curvature of the displacing body in relation to that of the displacing chamber being dimensioned such that the displacing body almost touches the inner and outer circumferential walls of the displacing chamber at in each case at least one sealing line continuously advancing during operation. In order to achieve as simple a construction as possible in such a positive displacement machine and, furthermore, to make possible in a simple manner unpressurised operation, the displacing body is to be formed by a continuous strip (9) of annular design which engages in the displacing chamber (5), which is likewise of annular design. Furthermore, each of the two crescent-shaped working spaces (38, 39) formed between a displacing body (9) and the circumferential walls of the displacing chamber (5) is to be assigned an inlet opening (34) and an outlet opening (35) which are separated by a separating sliding vein (25, 42) vane essentially radially in the housing (3) and resting against the displacing body. <IMAGE>

Title: Process for recovering glucose and fructose from inverted molasses
Inventor: SCHNEIDER HANS-GEORG DIPL CHEM
IPC: C13K3/00
Filed: 1982-08-21
Abstract: Known processes for recovering fructose from molasses were not economical because of the high consumption of auxiliary chemicals and the low yield. The aim of the invention is to recover both fructose and glucose in high yield from this cheap raw material by an economical process. According to the invention, this is achieved by first subjecting preferably enzymatically inverted molasses to a phosphate precipitation and passing the solution thus purified via a first cation exchanger in a monovalent salt form. The fraction formed in elution having the highest content of invert sugar is passed via a second cation exchanger in the calcium form, from which exchanger substantially separated fractions of glucose and fructose are removed, from which the nonsugar substances are then separated using ion exchangers.

Title: Oil preheater for heating oil and oil preheating system
Inventor: ERAT PETER
IPC: F23K5/20
Filed: 1982-09-02
Abstract: The invention relates to an oil preheater for heating oil and an oil preheating system for heating to a predetermined operating temperature the heating oil to be fed to a burner. The oil preheater is divided into two chambers (K1, K2), through which an oil duct (3) in the form of a pipe loop (4) is passed. Preheating by means of a heat carrier (6) takes place in the first chamber (K1), and an after-heating by means of a heating rod (5) can take place in the second chamber (K2). The operation of the oil preheater is controlled by control devices such that, in the burner start-up phase, the oil pressure is initially kept to a low value and the pressure is only raised to the normal operating pressure after a given starting time. The burner is thus relieved during start-up. <IMAGE>
