Title: Signal headlight on radiators and car roofs
Inventor: KLINGLER ERNST
IPC: B60Q1/54
Filed: 1988-01-28
Abstract: Signal headlights on radiators and car roofs are mounted in a housing or in a rectangular pipe therein between two rubber [lacuna] on an axis between two rectangular pipes as a housing base. The headlight which can pivot on the axis in the event of change of speed indicates this by different light colours of the light source and on the headlight outline precisely by the light being reflected during this process between two protective glass plates and from a metallised mirror and from its two strips at two walls of the mirror and from these to the headlight outline from windows in a green, red and colourless fashion. At constant speed two rubber bands put the headlight in a straight position and only let it tremble. The housing of a headlight above the radiator of a car can be lifted off over it by means of a lock; when fitted on and locked, this headlight serves to colour the lights of a headlight to the rear on the roof of a car travelling ahead and thus to maintain the same speed of the vehicle. This somewhat larger, but identical headlight on the roof of the car does not require a lock but rather only two round bars in order to be able to move it into the car from the housing let into the car and to be able to gain access to it there. <IMAGE>

Title: Device for controlling the speed of a hydraulic motor
Inventor: WEIGLE DIETER DIPL ING
IPC: F16H61/46
Filed: 1988-08-05
Abstract: The device for controlling the speed of a hydraulic motor for driving an auxiliary unit in a motor vehicle has, in the delivery line (16) of the pump (10), a pressure compensator (25) which is assigned a variable metering orifice (26). Via the pressure compensator, the pressure-medium flow metered in flows to the hydraulic motor (17) independently of the speed of rotation of the pump. When no power is required at the hydraulic motor, only a very small flow of pressure medium flows to the latter. This small flow of pressure medium is controlled by the metering orifice (29) and the pressure compensator (25) independently of the load-pressure condition in the load. If the pressure at the load increases due to an adjustment to a pressure regulator on the hydraulic motor, the pressure-dependent metering orifice (26) connected in parallel opens and increases the supply of pressure medium to the hydraulic motor, in particular as a function of the level of the system deviation. In this way, a simple and economical means of controlling the hydraulic motor is obtained. <IMAGE>

Title: Process for the preparation of a solid waste product for the ultimate storage of radioactive substances
Inventor: FROEHLICH HANSKURT
IPC: G21F9/16
Filed: 1988-12-03
Abstract: Process for the preparation of a solid waste product which is suitable for the ultimate storage of radioactive waste substances embedded therein, using a curable matrix material known under the term geopolymer "Trolit<R>", in preferably flowable and/or foamed form, in which the solid or liquid radioactive waste substances are embedded by mixing with the matrix material or by pouring the matrix material over them, a microwave treatment being carried out for curing and drying the matrix material together with the waste substances embedded therein instead of and/or before, after or during a heat treatment, this microwave treatment triggering polycondensation of the matrix mixture and water liberated during this process being expelled more rapidily. The removal of water can be improved by applying a subatmospheric pressure during the drying process. Foaming of the matrix material advantageously reduces the density of the waste product in an advantageous manner. The exceedingly low water content of the dried waste product results in virtually no formation of radiolysis gas.

Title: Soil covering made of (concrete) blocks
IPC: E01C5/00
Filed: 1988-12-21
Abstract: In the case of soil coverings (paved surfaces) made of (concrete) blocks with gaps enabling plant growth, the uniform configuration of the gaps is achieved by arranging spacers between the (concrete) blocks. Until now, soil coverings have been known, the spacers of which possess vertical plant channels and are accordingly constructed such that they form vertical separating walls within the gaps. These separating walls constitute a considerable hinderance to the transverse development of the roots which is required for uniform growth of the grass. The novel soil covering is intended to hinder in no way the plant growth within the gaps, while securely supporting the individual (concrete) blocks. The soil covering is provided with spacers (13) consisting of three horizontal supporting walls which are arranged at approximately the same distance from one another and are interconnected by two connecting struts (15). This type of open construction enables transversely or horizontally running, through-openings, thus making unhindered plant growth possible. Soil coverings with plant gaps. <IMAGE>

Title: Actuation device for the parking brake of a motor vehicle
Inventor: BOLL WOLF DR ING
IPC: F16C1/12
Filed: 1989-02-15
Abstract: An actuation device for the parking brake of a motor vehicle is described which acts in each case via a Bowden cable on the brake elements of the wheels of an axle of a vehicle. In order to actuate the Bowden cable an intermediate lever is used which lies between the Bowden cables and a pulling element which can be actuated manually or by pedal and on which the two Bowden cable cores are supported in such a way that when they are made to pivot by the pulling element they are pulled in opposite directions. For this purpose, an anchoring element which extends away from the intermediate lever counter to the pulling force which can be exerted by the pulling element and which can be moved transversely with respect to the pulling force is supported on the said intermediate lever in such a way that a distance which is present between the lever-side supporting points of anchoring element and pulling element forms a lever. The lever-side supporting point of the anchoring element is located between the lever-side supporting points of the Bowden cable cores and in the region of a connecting line which extends between these supporting points. This structure permits an intermediate lever bearing fixed to the vehicle body to be dispensed with and selectable force transmission to be established between the pulling element and Bowden cable cores.
