Title: Motor vehicle with interior trim which has surface-structured fitting parts and metal fitting elements which are lined with plastic
Inventor: HEISS WERNER DIPL ING
IPC: B60R13/02
Filed: 1988-07-26
Abstract: A motor vehicle with interior trim is specified, in the case of which there are provided surface-structured fittings and, in addition, fitting elements made of a metal support which is lined with plastic. To create a surface structure which is suitable for the structured surface of the fittings, the surface of the metal supports is provided with a surface structure which corresponds to the surface of at least one fitting. In the case of the fitting elements, the surface cover is formed by a plastic layer which is applied to the support and the surface structure of which reproduces the structure of the metal support. Fitting the interiors of motor vehicles with such lining elements improves their appearance, making them generally more pleasing to the eye.

Title: Control valve, especially for hydraulic brake systems with slip control
Inventor: GOEHRING FRANK
IPC: F16L55/05
Filed: 1988-10-22
Abstract: Control valve, especially for hydraulic brake systems with slip control, with an inlet bore (14) arranged in a receiver body (1) and an outlet bore (15) and a plate-shaped valve device (2), displaceable against the force of a spring (5) in the direction of flow of the medium and having a restrictor (7), at least one return bore (3) passing through the receiver body (1) up to one face of a chamber (4) of the receiver body (1) in contact with the valve device (2), so that the return bore (3), branching off from the closed control circuit of a hydraulic brake system with slip control, ends in a reservoir preferably at atmospheric pressure. Control valves hitherto arranged in the pressure medium circuit of a hydraulic brake system with slip control have the disadvantage that in slip-controlled braking strong pressure pulses give rise to a level of noise, so that pressure pulses and hence the noise can be effectively damped or decoupled by the arrangement of the control valve according to the invention in the hydraulic circuit. <IMAGE>

Title: Container for cooking food
Inventor: HARTMANN RUDOLF
IPC: A47J37/04
Filed: 1989-01-30
Abstract: This container can be used for cooking food. It is made either of clay or ceramic. By the uniform, rotating movements effected by an electric motor, uniform cooking is achieved. The mounting for receiving the container is connected to the electric motor by a shaft. By employing a plurality of containers, different food can be cooked simultaneously, thus saving an enormous amount of time and facilitating the work. By trapping the heat produced, a high energy saving results. The reuse of the containers is environmentally friendly. By preparing the food in the containers, it would be possible for anyone to prepare food for themselves with little effort at the appropriate location. The energy source can be an electrical system or a grilling fireplace with open fire.

Patent DE-3907941-A1 (DE)
Title: Steel tube support which can be beaten out, and beating-out tool therefor
Inventor: GREBE HORST
IPC: E04G11/48
Filed: 1989-03-11
Abstract: Steel tube support which can be beaten out, and tool for beating out the outer tube of such a steel tube support. During the shuttering removal of concrete structures, the steel tube supports used are often released from their operating position by striking their lower end with a hammer. This frequently results in indents on the outer tube which impair the functional capacity of the steel tube support. By means of the invention, indents are intended to be removed from damaged steel tube supports in a simple and effective manner. In order to introduce a peg-like beating-out tool into the outer tube of a steel tube support, the foot plate provided on the outer tube is given a central opening whose diameter corresponds to the internal diameter of the outer tube of the steel tube support. Cams projecting into said opening serve as bearing means for the inner tube. The beating-out tool which is to be driven into the outer tube has a cylindrical head whose external diameter is adapted to the internal diameter of the outer tube of the steel tube support. Grooves running in the longitudinal direction make it possible to slide the beating-out tool beyond the cams projecting into the interior of the opening of the foot plate. It is thus possible, from the foot end of the steel tube support, to beat out the outer tube of said support on site with means available on building sites.

Patent DE-3919108-A1 (DE)
Inventor: BERGER JOACHIM DIPL ING
IPC: F02P5/15
Filed: 1989-06-10
Abstract: A step-change in an engine operating parameter such as engine fuel or air supply or ignition, is brought about when a computing unit 36 detects a change in a dynamic operating state of a motor vehicle, e.g. from the output of an accelerator pedal position sensor 49. The size of the step-change is dependent on the difference between the actual acceleration of the vehicle derived from vehicle speed sensor 45, and a desired acceleration derived from sensor 49, and perhaps the output of a selected-gear sensing device 45. The engine may also have a control system 23, incorporating a vehicle speed regulator, which determines basic values for the engine operating parameters. <IMAGE>

Patent DE-3924268-A1 (DE)
Inventor: SCHINDLER STEFAN DR
IPC: C22C1/10
Filed: 1989-07-22
Abstract: To date, highly porous ceramic materials have been infiltrated with a metal melt so that the product produced therefrom has a predominantly metallic structure. This ceramic-metal composite (CMC) is substantially metal-like in its properties, so that the requirements with regard to hardness, heat stability and wear are well below the values of the purely ceramic materials. The properties of the ceramic materials with regard to flexural strength, toughness, modulus of elasticity, hardness and resistance to wear are to be improved while retaining or increasing the properties such as hardness, temperature behaviour and resistance to wear, which are superior compared with metallic materials. The metal-ceramic composite is characterised in that the ceramic is composed of several layers, the layer thickness being between 10 and 150  mu m and the mean pore radius between 100 and 1000 nm with a final open porosity of 5-14% and a total porosity of 5-30%, and the metal fills the pore volume except for a residual pore volume of 0.1 to 10%, based on the initial porosity. The ceramic-metal composite is preferably used for binding to metal structures, such as welded or soldered ceramic/metal constructions.
