Title: Circuit arrangement for operating low-pressure discharge lamps in individual mode and tandem mode
IPC: H05B41/24
Filed: 1986-12-31
Abstract: The novelty is an electronic ballast for low-pressure discharge lamps = fluorescent lamps having an operating frequency of 20 kHz to 40 kHz, the current path from the positively switching transistor to the negatively switching transistor being passed via inductances. Furthermore, a series circuit = tandem circuit of fluorescent lamps of any desired power level is provided, the preheating current being passed via an inductance to the starting capacitors, which inductance triggers a current-limiting pre-heating effect. For the tandem circuit having fluorescent lamps of relatively high performance, the pre-heating current is split via a diode and capacitor circuit in order that the heating filament is not overloaded. Furthermore, the operating frequency is maintained by means of an LC element, even if the smoothing level on the supply voltage and on the operating voltage of the lamps falls. Furthermore, elements which limit switching are used, which prevents the transistors being overdriven from the base. A separate contact holder of the supply voltage of the lamp and of the starting capacitor is provided for adaptation of two-pin lamps having built-in starters. Furthermore, power conversions are possible, with the same circuit arrangement for tandem operation and the operation of an individual lamp.

Title: Sales vehicle
Inventor: LEISENTRITT REINHOLD
IPC: B60P3/025
Filed: 1987-03-28
Abstract: In order to increase the roof surface of a sales vehicle, the intention is to design the latter in such a manner that on transferring a roof-surface part from a vertical position into a horizontal position the required clearance can be kept as small as possible, and then, in addition, the outer surfaces form the upper side of the roof. The roof-surface parts (17 and 18) have a hinge (22) in their end regions, one hinge part (22b) being equipped with rollers (23a, 23b) in order to move the respective roof-surface part (17, 18) along the guide rail (21). In the outer end position the respective roof-surface part (17, 18) can then be pivoted around the hinge pin (22c). The suspension, according to the invention, of the roof-surface parts can be used particularly for sales vehicles or sales trailers which are erected for instance at market places. <IMAGE>

Title: Apparatus for measuring the viscosity and density of liquids
Inventor: WILKE JUERGEN DR SC TECHN
IPC: G01N9/00
Filed: 1987-04-11
Abstract: The invention provides for the quasi-continuous measurement of density and viscosity of, preferably low viscosity, fluids and is therefore suitable, for example, for quality control in the foodstuffs industry and in biotechnical processes. Aim of the invention is an apparatus which allows the viscosity and density of a small amount of measurement material to be portrayed almost simultaneously as an electrical signal which makes possible immediate further processing by microprocessor to give the required material and quality parameters. According to the invention, the object is achieved by a combination of a capillary viscometer and a vibrational density measurement device in the following way: the functional unit determining the measurement signal formation of both measurement parameters is used both as outlet capillary of the viscometer and for density-dependent vibration generation.

Title: Method and circuit arrangement for controlling the torque of an asynchronous machine using a delay element
Inventor: KOECK FRITZ
IPC: B60L3/10
Filed: 1987-04-30
Abstract: The method is suitable for controlling the torque of an asynchronous machine (1) which is used as a drive for a vehicle and is fed from a direct current source (3) or alternating current source via a power inverter (2) or inverter from a direct current source (3) or alternating current source. The stator frequency (f1) is formed by adding a fed-back actual value (fn) for the frequency of rotation and a preset slip frequency value (f2v) which corresponds to a predetermined torque (M). The feeding back of the actual value (fn) for the frequency of rotation takes place here in a delayed fashion. The delay effect is adjusted continuously as a function of a comparison between an actual value, such as vehicle speed, wheel speed, vehicle acceleration and resonant oscillation of the drive train, which describes the instantaneous behaviour of the vehicle and a predetermined set value. As result, it is possible to apply a tensile force or breaking force in an optimum fashion with the most varied coefficients of adhesion. <IMAGE>

Title: Safety dam for the drivage of underwater tunnels in compressed air
Inventor: SCHERLE MAX DIPL ING
IPC: E21D9/04
Filed: 1987-10-03
Abstract: Method of securing tunnel drivages under water against blow-out and air loss by constructing a travelling safety dam. When driving tunnels under water in compressed air it can be difficult to achieve the requisite safety against blow-out. The hitherto conventional filling of sloped dams on the bed of the body of water is not always able to provide a remedy. According to the invention, a travelling safety dam is constructed over the underwater tunnel to be driven. The lateral boundary of the safety dam extends from sheet-pile walls, guided in the lock, under shield apexes, and its filling consists of loose rock, which allows the compressed air to rise with the requisite flow resistance, and is taken so high that the surcharge necessary for protecting against blow-out is achieved. The lateral sheet-pile walls together with the filling prevent an uncontrollable lateral escape of compressed air. Furthermore, from the safety dam, sounding wells for accurate location finding are sunk, soil data is obtained, and injections for improving the soil for driving in compressed air and for producing support and guidance for the tunnel are carried out. In the event of a blow-out hazard, the working face can be partitioned off by transverse sheet-pile walls.

Inventor: GROSSMANN HANS
IPC: D03D49/32
Filed: 1987-10-19
Abstract: There is described a picking mechanism for the weft insertion element of a weaving machine, comprising a pivot lever (1) which receives the energy for the insertion of the weft from a tension element (2) which is tensionable via a cam mechanism (3). The tension element (2) can in principle be any elongate element, for example a tension bar made of steel or a rope made of high strength aramid fibres. The cam mechanism (3) consists preferably of a toggle lever (4), which is extended and pressed somewhat beyond dead centre by a first cam disc (6) and which is forced back over dead centre by a second cam disc (7) to initiate the picking movement. A braking element (8) makes it possible to brake the picking movement of the pivot lever (1) at the end of the picking movement.

Patent DE-3737404-A1 (DE)
Title: Process and appliance for generating strongly adhering vacuum coatings
IPC: C23C14/32
Filed: 1987-11-04
Abstract: In the PVD processes currently used for coating workpieces, the adhesive strength (bond strength) obtained of the coating film on the substrate (workpiece) is low, since the operating temperature has to be kept relatively low. Consequently, the workpieces coated by means of the conventional PVD processes cannot be subjected to heavy mechanical demands. The novel process and the appropriate appliances make it possible to effect, at relatively low temperatures, a high adhesive strength of the coating film on the substrate, by generating, by means of systematic modifications of, and additions to, the conventional PVD processes such as vacuum deposition by cathode sputtering, by vapour deposition and ion-protected coating, a ramp-like bonding layer between the substrate and the surface layer, i.e. the concentration of the coating components gradually decreases in the direction of the substrate, and in the same proportion that of the substrate components increases. For example, in the cathode sputtering appliance the following processes are repeated cyclically as a result of the workpiece alternately adopting the role of the anode and the cathode: coating of the workpiece - cathode sputtering of the thin film and part of the substrate - back-diffusion of the sputtered particles, with the end result of a ramp-like bonding layer.
