Title: Control device on paper feeders and delivers of polygraphic machines
Inventor: GLOSE FRANK
IPC: B65H31/18
Filed: 1986-03-11
Abstract: The invention relates to a control device on paper feeders and delivers of polygraphic machines, in particular on flat-stack feeders. The aim of the invention consists in providing a control device for advance control which does not prevent correct separations and at the same time effects an increase of the service life. The technical object consists in designing the device such that the correction speed is adapted to the magnitude of the deviation of the advance from the set point value and is slowed at it approaches the set point value. This object is achieved in that the analogue stack-height sensor has connected downstream of it an analogue evaluation and control device which processes the measurement values coming from the stack-height sensor and adapts the adjustment rate to the magnitude of the deviation and said evaluation and control device has, connected downstream, an infinitely variable drive. The technical outlay is low if, in the evaluation and control device, the stack-height sensor is connected to an oscillator circuit and the latter is connected, via a rectifier circuit, to an adjustment element controlling the adjustment rate. <IMAGE>
Patent DE-3616555-A1 (DE)
Title: Degassing device
Inventor: BERGEMANN ULRICH-JOACHIM DR IN
IPC: C02F1/20
Filed: 1986-05-16
Abstract: For thermal degassing for example of turbine condensate in a feed-water container, spray systems are used, which spray the water to be degassed in the upper region of the feed-water container. They are provided with a water supply pipe which passes through the container wall from the top and the lower opening of which is surrounded by a water cup which has radial bores for generating spraying jets which emerge on all sides. These bores are arranged above one another in a number of rows, only the lower ones of which are acted upon in the part-load range. Steam from the interior of the container can penetrate into the water cup through the upper ones and condense on the water supply pipe which has approximately the temperature of the water supplied. In order to avoid pressure shocks arising as a result of this, the water supply pipe is heat insulated in the region surrounded by the water cup. Instead or in addition to this, the bores can be made with a bore diameter which increases from the bottom to the top, with overall cross-section remaining constant.

Patent DE-3637716-A1 (DE)
Title: Method of zinc plating all types of steel parts
Inventor: MAIWORM RUDOLF
IPC: C25D5/36
Filed: 1986-11-05
Abstract: The steel surfaces of polymeric plastic/steel joints have hitherto been zinc-plated by the Sherard process. The disadvantage is, however, a very rapid surface corrosion as a result of the approximately 10 to 20% proportion of iron in the zinc layer. A rapid white-rust formation is also observed. The porousness of the zinc layer may result in crack formation down to the base material and bring about corrosion in the base material. Electrolytic zinc plating cannot be used since the rubber or the plastic cannot be made to adhere to the steel. The method in accordance with the main patent 3531068 provides, on the other hand, for the steel parts of the joint first to be treated by the Sherard process then vulcanised with the rubber or plastic parts, then to be zinc plated electrolytically. In this way, an electrolytic zinc layer which is keyed into the surface and covers the porous layer is laid down on the Sherard layer. The susceptibility to corrosion is substantially reduced and the surface life of the joint is increased. The invention extends this process to the zinc plating of all types of steel parts.

Title: Arrangement for controlling the pressure of a damping cylinder for the suspension of vehicles
Inventor: BARTHOLOMAEUS REINER DIPL ING
IPC: B60G17/056
Filed: 1986-11-12
Abstract: For the suspension of a vehicle axle a damping cylinder is provided, which is designed as a differential cylinder, the pressure in the piston-side cylinder chamber being controlled by a servo valve. The servo valve is triggered by an electronic control unit, which processes a plurality of input signals. If the hydraulics and/or the electronics fail, the working pressure in the damping cylinder, required for the suspension, must be reduced to a load pressure serving to support the vehicle. For this purpose, a control valve switches to a throttle position and a pressure limiting valve is reversed, which by way of a reversing valve is then locked again by the load pressure at the pressure stage of the working pressure.

Title: Sealing element which can be added between the roof covering and the ridge covering of saddleback roofs
Inventor: KNOCHE ALFONS
IPC: E04D13/17
Filed: 1987-02-09
Abstract: In the case of such plastic sealing elements, there is the problem of the edge parts, which are to be brought to bear against the roofing skin (roofing tiles), raise the seal, especially under the influence of pronounced fluctuations in the outside temperature, from the roofing skin, thereby causing damage. This is counteracted in that the bearing means (241) for the ridge tiles, which engage over the sealing element, are arranged on said elements in the region of the bending zone (B), between the sheet-like parts (e.g. 112), adjoining the longitudinal central web (e.g. 11) of the element, and the edge parts (e.g. 113), such that they span such bending zone (B). In this arrangement, the ridge tiles, via the bearing means (241), permanently make the edge parts (e.g. 113) of the sealing element tend to butt against the roofing tiles in a sealed manner. <IMAGE>
