Title: Inclined hoist, in particular furniture lift
Inventor: BOECKER ALBERT
IPC: B66B9/16
Filed: 1986-08-21
Abstract: The invention concerns an inclined hoist, in particular a furniture lift with a number of telescoping sections running one within another, forming guide rails for a load platform that can move along them, with a hydraulic cylinder or a winch rope running over block and tackle being provided between the first (lowest) telescoping section and the second telescoping section. The essence of the invention is that the extension of the telescoping sections following the second telescoping section is performed by chain segments of finite length, which each run from the upper end of a telescoping section via the upper end of the next telescoping section to the lower end of the following telescoping section. The carrying chains, which take the form of pin chains, have retaining chains associated with them, which take up the load if a carrying chain breaks. According to the invention, interlocking devices between the individual telescoping sections can be dispensed with, or if a winch is used, only an interlock between the first and second telescoping sections is needed, and further interlocks between the subsequent telescoping sections can be dispensed with. <IMAGE>

Title: Room lighting system
Inventor: SCHWANKHART HELMUT
IPC: F21V21/34
Filed: 1987-01-19
Abstract: Known room lighting systems with bars running around along the walls of the room for clamping on lamps/lights do not offer an aesthetically pleasing solution in the area of walls with windows. In addition, they are heavy and bulky, On walls with windows, the bar which otherwise serves for mounting the lamps/lights is continued, at least in the window areas, as a curtain rail and can be fitted at a distance from the wall adapted to the windowsill projections. By forming the rod from a transparent material, such as polyacrylic resin, an airy lightweight effect is achieved. The room lighting system is suitable for display windows, living rooms, commercial premises, baths etc.

Title: Method for controlling and monitoring a number of identical or different bolt welding devices
Inventor: SOYER JUN HEINZ
IPC: B23K9/20
Filed: 1988-04-20
Abstract: In the case of a method for controlling and monitoring a number of identical or different bolt welding devices, by means of which welds of metallic bolts to metallic base material can be carried out in the case of arc bolt welding, a constant sequence of square-wave pulses having a period of 20 ms is produced as a control clock to control a welding cycle, which sequence is derived from the 50 Hz frequency of a single-phase or three-phase alternating current. Furthermore, each welding cycle is always started only during a zero crossing of the alternating current in a specific, fixed direction, that is to say with the front edge or rear edge of a square-wave pulse, and each individual section of a welding cycle is always an integer multiple of the square-wave pulse period. Furthermore, a mean value of a predetermined number of test welds is formed for each individual section of a specific welding cycle for each of the number of welding devices, and this mean value is then stored in a memory such that it can be called up. Finally, in the case of the method according to the invention, a variably adjustable bandwidth tolerance is specified, related to the amplitude of the stored mean value.

Title: Hydrostatic steering system
Inventor: TISCHER WERNER
IPC: F15B11/16
Filed: 1988-06-21
Abstract: A hydrostatic steering system is provided with a pump (2) connected to a tank (1), with a steering valve (4) having a metering pump (6) which can be operated by a steering wheel (7), and with a steering cylinder (13). The steering system has a variable working flow and a constant pilot flow, the pilot flow flowing via a fixed orifice (6) and the pressure drop across the fixed orifice serving as a control signal for the delivery flow in a pressure feed line (3). The metering pump is coupled mechanically to a variable orifice (15), via which the pilot flow flows. Between the fixed orifice (6) and the variable orifice (15) there is a pressure compensator (16) which is controlled by the differential pressure of the variable orifice. The load signal is tapped off by means of a control line (18) which branches off between the fixed orifice (6) and the pressure compensator (16), this control line leading to the pump (2) or, in the case of a constant displacement pump with a downstream flow-dividing valve (21), to the flow-dividing valve. <IMAGE>

Title: Process for producing ceramic components with exploitation of the waste products of the mechanical and chemical processing of black coal
Inventor: SZULAKOWSKI WACLAW DR
IPC: C04B33/32
Filed: 1988-06-24
Abstract: The process for producing the ceramic components with exploitation of the waste products of the mechanical and chemical processing of black coal (bituminous coal) makes possible an improvement in the quality, the production of ceramic components having complicated shapes, production growth with simultaneous reduction in the production costs compared with the known processes and also a considerable reduction of the sulphur, soot and flyash emissions into the atmosphere. The process of the invention comprises the use of the flotation tailings of the black coal and the coking wastes of the coal, i.e. the tar oil, for preparing the ceramic composition, for drying and firing the products shaped therefrom. The flotation tailings as desensitising agent and energy carrier are introduced into the ceramic composition in an amount of from 5 to 20% by weight, with the coal substance contained therein being burnt in the ceramic furnace, with from 30 to 70% of the energy required for firing the products being supplied. The tar oil, on the other hand, by itself or as an oil-water-air emulsion without or with addition of coal dust is, after preheating to from 50 to 150@C exploited as the fuel burnt in the burners to effect the firing and for supplying the missing energy for carrying out the firing in accordance with the firing curve, because a part of the heat energy is generated by burning the flotation tailings pressed into the body of the products.
