Title: Rail wheel with rubber suspension
Inventor: RITTINGHAUS ROLF DIPL-ING
IPC: B60B17/00
Filed: 1982-06-11
Abstract: The rail wheel with rubber suspension has rubber elements arranged to form a ring element between the tyre of the wheel and the wheel disc. The deformation areas between the rubber elements extend obliquely with respect to the axial direction of the rail wheel.

Title: Arrangement for automatically scanning the length of a workpiece, in particular for frame presses
Inventor: BRINKMANN HERMANN
IPC: G01B21/02
Filed: 1983-02-02
Abstract: The invention describes an arrangement for automatically scanning the length of a workpiece, in particular of a frame piece inserted into a frame press. A measuring sensor which can be moved parallel to the workpiece by a servomotor transmits a signal M when it detects the workpiece, and upon closure of a start contact which indicates that a workpiece is inserted, a signal K of defined duration is transmitted. A control logic generates signals AW and AW to drive a servomotor which moves the measuring sensor up to the workpiece (AW) or away therefrom (AW). The signals SA/W and SA/W indicate whether the measuring sensor is currently moving up to the workpiece or away therefrom. The control logic can be constructed, e.g., in the form of electromechanical drives or logic circuits, and fulfils the conditions of the truth tables specified in Claim 2, preferred embodiments being given by the Boolean equations. <IMAGE>  and <IMAGE> repectively

Patent DE-3308574-A1 (DE)
Inventor: BRUNNER RUDOLF
IPC: F15B13/04
Filed: 1983-03-10
Abstract: The invention relates to a hydraulic control valve comprising a housing with a housing bore (2) formed therein, a control piston (3) being guided in said housing bore for sliding displacement between a neutral position (n) for zero-pressure through-flow and at least one control position (I, II), and further comprising a pressure inlet (6) opening in said housing bore (2), a through-passage (8) in said control piston (3), and a discharge outlet (7) communicating with said pressure inlet via said through-passage in the zero-pressure through-flow position. In a control valve of this type, particularly if employed in a high pressure hydraulic system, displacement of the control piston from a control position to the neutral position is hampered by unsatisfactory pressure compensation. In accordance with the invention, this undesirable effect is avoided by forming substantialy diametrally opposite said discharge outlet (7) a relief area (9, 9', 16, 17, 18, F26) compensating at least the effective area of said discharge outlet and being of substantially the same size as the discharge outlet and subjected to the same pressure as the latter. For ensuring effortless displacement of the control piston of an upstream control valve from its neutral position in a battery-type arrangement of a plurality of control valves even if a downstream control valve is in its control position, there is further provided an area (33) compensating the effective area of the relief area (9, 9', 16, 17, 18, F26) said compensating area communicating with return pressure at least in the neutral position (N).

Abstract: Method for the production of hydraulically bonded panels of pressed material, pressed material consisting of chips and/or fibre material, cement and mixing water, if required with additives, being shaped to give panel blanks of pressed material, the panel blanks of pressed material being stacked with the interposition of pressure plates with the free edge projecting beyond the free edges of the panel blanks of pressed material, and being held together in the stack under a pre-hardening pressure which, in the case of homogeneous pore distribution in the panels of pressed material, leaves free a certain pore volume. The pressure plates used are designed as heat-conducting plates and their free edge interacts as a heat exchanger with the hot water. The panel blanks of pressed material are exposed, in a stack, to a pre-hardening pressure of 100 to 400 N/cm<2> in such a way that a sufficient volume of pores remains free for the absorption of from 1 to 10 % by weight of water. The stack is dipped in flowing hot water and the temperature of the panel blanks of pressed material in the stack during pre-hardening is controlled or regulated via the adjustable temperature of the hot water. A plant set up to carry out the method has a hot water supply designed as a dip tank into which at least one stack can be dipped with the aid of a device designed as a crane for manipulating the stack. The dip tank has a circulation device and a heating and cooling device for the hot water, the quantity of which is sufficient in order ... Original abstract incomplete. <IMAGE>

Title: Solid electrolyte tube for high-temperature water electrolysis
Inventor: ESPER FRIEDRICH JOSEF DR
IPC: C25B13/02
Filed: 1983-07-13
Abstract: A solid electrolyte tube is proposed which is used in the high-temperature vapour-phase production of hydrogen by electrolysis. The solid electrolyte tube is preferably composed of stabilised zirconium dioxide and is produced by pressing and sintering methods which are standard in ceramic technology. It has an essentially hollow-cylindrical shape, but has a wall thickness which is less than that found necessary for strength reasons if the wall thickness is kept constant and exhibits at least one bead-like thickened section on its outer contour. Preferably, the ends also exhibit a thickened section of this type. The wall thickness in the bead-like thickened section is 1.5 to 2.5 times the wall thickness of the rest of the tube. In this way it is possible, for example, to reduce the wall thickness of most of the tube from 0.5 to 0.3 mm. <IMAGE>

Title: Externally heated regenerative heat engine and machine
Inventor: EDER FRANZ X PROF DR ING
IPC: F02G1/043
Filed: 1983-09-16
Abstract: The invention comprises two cylindrical working cylinders in which a circular displacement piston is made to roll along each of the cylinder walls by means of an eccentric, which piston by means of two sprung sealing strips divides the volume of the working cylinder into two working chambers. The two eccentrics are fixed on a common shaft and are jointly driven by an auxiliary motor; eccentrics and the planes of separation defined by the sealing strips are rotated in opposition to one another approximately by 90 DEG . The upper working chambers of the two working cylinders divided by the sealing strips and eccentrics are directly connected to one another by way of a heating heat exchanger, a heat recovery unit and a cooler, the corresponding lower working chambers by a line, and filled with a gaseous or vapour working medium at high pressure. If heat is fed to the working gas by way of the heating heat exchanger and a smaller amount of heat withdrawn from it in the cooler, a heat engine or a heat pump is obtained according to whether the circular piston of the heated working vessel leads or lags behind that of the cooled working cylinder. For improved thermal insulation of the heated working cylinder this and the piston rotating in it are composed of ceramic material.
