Title: Brake antilock device
Inventor: BELART JUAN
IPC: B60T8/34
Filed: 1981-09-15
Abstract: In a brake antilock device for the wheel brakes of a motor vehicle a normally open 2/2-way valve (2) is inserted into the common brake line (7) of a brake circuit (1) leading to the wheel brake cylinders (5, 6). The common brake line divides into at least two brake conduits (8, 9), at least one (9) of the brake conduits (8, 9) of a brake circuit (1) being directly connected, that is without an additional 2/2-way valve, open in normal braking, to a wheel brake cylinder (6), which is assigned to a vehicle wheel most involved in the total braking effect. The remaining brake conduits (8) contain additional 2/2-way valves (3), open in normal braking, assigned to wheel brake cylinders (5). Downstream of the 2/2-way valve (2) the common brake line (7) has a branch in the form of a return (10) to a reservoir (11) at zero pressure with an inserted, normally closed 2/2-way valve (4) (fig. 1). The brake conduit (9) directly connected to the wheel brake cylinder (6) is assigned in particular to the front axle of a vehicle and/or to a front axle of a vehicle double axle. The direct brake conduit (9) can also be assigned to left-side vehicle wheels, which encounter better frictional adhesion conditions on a road surface. Brake pressure reducing devices on the rear axle and/or brake boosters on the front axle reduce any brake power losses in the case of common control in one brake circuit. By means of the invention a structurally simple, cost-effective brake system is created which is capable of functioning fully in practical operation.   <IMAGE>

Filed: 1981-10-03
Abstract: Mixtures which are used for the production of polyurethane foam and which contain amines having primary or secondary aliphatic hydroxyl groups, and also customary quantities of trichlorotrifluoroethane and/or trichlorofluoromethane as a blowing agent, can be stabilized against the premature reaction of the components by adding 0.05 to 5% by weight of 2,4-diphenyl-4-methylpentene in which the ratio of the 2,4-diphenyl-4-methyl-1-pentene isomer to the 2,4-diphenyl-4-methyl-2-pentene isomer is 1:1 to 9:1, the percentages relating to the chlorofluoroalkane. In particular, these mixtures can be stabilized by adding 0.1 to 5% by weight of a mixture consisting of 45 to 89% by weight of 2,4-diphenyl-4-methyl-1-pentene, 10 to 45% by weight of 2,4-diphenyl-4-methyl-2-pentene and 1 to 20% by weight of 1,1,3-trimethyl-3-phenylindane.
Patent DE-3143916-A1 (DE)
Title: Electromagnetic operating device
Inventor: STAIB HORST
IPC: F16K31/06
Filed: 1981-11-05
Abstract: The electromagnetic operating device according to Figure 1 has an armature (16) which is arranged in a housing (10) and is arranged such that it can be tilted about its outer edge (16) with the aid of spring elements (22, 45, 47, 50). When the electromagnet is not energised, the armature acts on a plunger (24) by spring force, which plunger (24) operates a valve body (25). When the electromagnet is energised, the armature is attracted and the plunger is guided back to its other limit position. The spring element is advantageously constructed as a leaf spring. If it is constructed of non-magnetic material, then magnetic sticking can be prevented in this way. The described operating device results in a simple apparatus which reacts quickly. <IMAGE>

Title: Colour television screen
Inventor: HACHT GERHARD VON DIPL ING
IPC: H04N9/12
Filed: 1982-01-23
Abstract: To manufacture flat screens for colour television, systems have been proposed in which the glow discharge principle is used for generating the colours. Since evacuated spaces with a glass wall cannot be fabricated to be arbitrarily large, such screens, in practice, remain at the current size of the picture tubes. It has also already been proposed to use screens which are composed of a multiplicity of light-emitting diodes. Screens of this type, however, are affected by a large number of design problems. According to the invention, it is proposed that rod-shaped light sources blending into one another and having three or more cylinder zones project like a horizontal line-shaped band of rays in three primary colours or more and in three different wavelengths or more onto a duo-band glass cylinder surrounding the rod-shaped light sources, which cylinder is a carrier of strip-shaped controllable Faraday light switching cells and the cylinder circumference of which is engaged by foil packets of light-collecting luminescent plastic foils or plates into which the multi-frequency wavelength radiation enters through a window and allows luminescences in three or more different wavelengths to light up in the plastic and in which the luminescent light is transported to a narrow edge of the foil packet where it passes through a vertically arranged Faraday light switching cell wall and then allows light impressions of different colours to arise on a planar screen panel.

Title: Window composed of a frame made of a material which is essentially not fire-resistant and of a glass pane
Inventor: DIPPE HORST
IPC: E06B5/16
Filed: 1982-01-30
Abstract: Window composed of a frame made of a material which is essentially not fire-resistant, for example wood, and of a glass pane held in a groove which is formed between a fastening edge of the frame and a glass strip secured to the frame. According to the invention, the fastening edge and/or the glass strip is formed by board strips connected to the frame and made of fire-resistant material, for example asbestos-cement boards. The board strips are embedded in grooves and/or secured by means of screws. Thus, all the profile parts having a small cross-section or projecting outwards are formed from fire-resistant material, so that these profile parts particularly at risk from fire hold the glass pane longer in the event of a fire. <IMAGE>

Title: Auxiliary device for moving motor vehicles
Inventor: FISCHBACH HORST
IPC: B66D1/00
Filed: 1982-03-09
Abstract: My ideas are based on the premise that the driver of a motor vehicle has become stuck. Whether in snow, mud, gravel, sand or wherever it is not possible for him to continue under the vehicle's own force. Now, the driver fetches from his vehicle two cable drum attachments which are approximately the same size as a wheel cap and clamps them onto the rims of the drive wheels by means of a rapid-release fastening. He secures the cables which are approximately 25-30 m long as parallel as possible with the longitudinal axis of the vehicle to a fixed point or an anchor in the earth. By simply starting up the engine, forwards or backwards, the cables are wound onto the cable drums and thus shorten the path between the vehicle and the fixed point. In this way the ''winching'' effect is as strong as that of the vehicle motor. After the vehicle has reached firm ground again, the cable drum attachments are taken off again by unlocking the quick-release fastening and stowed in the vehicle. No external help is required during the entire process of freeing the vehicle. <IMAGE>

Inventor: SCHUSS WERNER DIPL ING
IPC: A61C17/02
Filed: 1982-03-10
Abstract: The present invention is directed to a dental spray hand piece which has a valve for controlling the flow of an agent through an agent line that extends through the hand piece to a spray nozzle and an arrangement for preventing dripping of the agent from an end of the nozzle when the valve stops flow of the agent through the line, characterized by the arrangement for preventing dripping including a hose section of elastic material being positioned between the valve and the nozzle, a thrust piece for acting on the hose section in an arrangement for moving the thrust piece from a position engaging the hose section and a second position partially deforming the hose section from an enlarged cross-section to a cross-section of the flow through the valve. Thus, when the valve stops flow the hose section resumes its enlarged cross-section which causes a suction to draw fluid in the line between the valve and the end of the nozzle inward from the end of the nozzle.
