Title: Hydraulic brake system
Inventor: SEIBERT WOLFRAM DR
IPC: B60T13/16
Filed: 1985-01-23
Abstract: The hydraulic brake system has two circuits (I, II) connected to brake callipers (36, 37, 38, 39). An auxiliary pump (11) provides a pressure source which can be regulated by a control line (49, 50) which projects from control valves (32, 33). The pressure from the pump first passes through a primary control valve (34, 35) before passing into the first valves via a connection (51, 52). The control valves can be regulated by solenoids to allow flow to pass from either the piston circuits or by passing down through the pump connections. This allows a twin circuit system to be controlled by an anti-skid unit.

Title: Composite pallet
Inventor: KUHLMANN JUERGEN ING GRAD
IPC: B65D19/40
Filed: 1985-02-08
Abstract: A composite pallet is designed according to the invention in such a way that the metal frames (3, 4), which enclose an upper deck (1) and a lower deck (2), are produced from sheet metal and are lock-seamed from below to the upper deck (1) and from above to the lower deck (2) and to support columns (8). In this case, the folded-over edge regions of the metal-frame sheets (3, 4) are recessed in the upper deck (1) and the lower deck (2) consisting of wood, plastic or the like in such a way that they are set back relative to their surface so that products to be stacked or the bottom can only be supported on the upper deck (1) or the lower deck (2). An advantageous design of the invention provides for the support columns (8) to be constructed as sleeves, preferably as punched mouldings. A reduction in weight compared to the known composite pallets results therefrom and also from the manufacture of the metal-frame sheets (3, 4) from sheet metal, these likewise preferably being constructed as punched mouldings. <IMAGE>

Patent DE-3513292-A1 (DE)
Title: Relay valve arrangement
Inventor: SHILTON BRIAN
IPC: B60T15/04
Filed: 1985-04-13
Abstract: The parent application P 3439086.3 proposes a relay valve arrangement with a first control surface and a second control surface with a shut-off means in the feed line of the control pressure to the second control surface, the shut-off means being designed in such a way that it is transmissive during the action of a signal pressure and is otherwise non-transmissive and connects the second control surface to the atmosphere. In this way, a relay valve arrangement is created which, when actuated during the period of action of a signal pressure, passes a higher pressure into a consumer circuit in a controlled manner than when actuated outside the period of action of the signal pressure. However, this solution has the disadvantage that, upon actuation outside the period of action of the signal pressure, response resistance in the consumers is only overcome at a higher control pressure. To eliminate this disadvantage, the supplementary patent proposes to design the shut-off means as a pressure-relief valve with a cut-off device. During the period of action of the signal pressure, the cut-off device cuts off the pressure-relief function of the pressure-relief valve. Outside the period of action of the signal pressure, the pressure-relief valve, provided the control pressure is below the limit pressure, is fully transmissive and beyond that is closed.

Title: Measuring device for setting running-gear parts of a motor vehicle, in particular a motor cycle, for moto cross events
Inventor: GRAUTHOFF FRIEDHELM
IPC: B62K25/00
Filed: 1985-04-24
Abstract: The invention relates to a measuring device for optimum setting of the damping strength and/or the biasing strength of the springs between two running-gear parts, arranged movably relative to one another, of a motor vehicle, in particular of a motor cycle, for moto cross events. The object of the invention is to provide a measuring device which substantially facilitates this setting without expensive novel developments or conversion costs thereby arising. This measuring device is characterised by a switching device which is arranged in the end region of the spring deflection of the movably mounted running-gear part and is operated by the movable part of the running gear when the desired maximum spring deflection is reached, and by a counter which indicates the number of pulses received via the switching device. When a specific number of pulses is reached, i.e. a specific number of excursions of the spring system is reached, when the entire route or a specific unit of the route has been travelled, both the damping and the spring biasing are set to a specific dimension which corresponds to the number of pulses.

Title: Process for producing pure semiconductor-material layers on semiconductor wafers by deposition from the gas phase
Inventor: HOLM CLAUS DIPL CHEM DR
IPC: C30B25/10
Filed: 1986-08-07
Abstract: In the process for producing layers of pure semiconductor material on semiconductor wafers, the wafers are aligned, according to the invention, in a row in a plane-parallel fashion one behind the other in an evacuable recipient. A chemical transfer reaction is then started and this transfers the material removed from each wafer to the opposite side of the adjacent wafer and deposits it there. Each wafer consequently acts simultaneously as source and substrate, with the exception of the first and last wafers in the row. Since the material deposited is, therefore, supplied by the wafers themselves, the material requirement is extremely low.

Title: Cross counter-current heat exchanger
Inventor: ROETZEL WILFRIED PROF DR ING
IPC: F28F27/00
Filed: 1987-01-15
Abstract: Cross counter-current heat exchanger originally with current flow in opposite directions. The said heat exchanger is made to approximate the effect of cross-counterflow in the same direction by rotating the external flow by 180@ between the passages or is at least improved by transverse mixing between the passages in the direction of guidance in the same direction. The rotation or mixing of the external flow is achieved by means of fixed guiding plates or by rotating blades. If only one pure transverse mixing is aimed at, other mixing elements are also possible, in the simplest case the extension of the main flow channel between the individual passages.
