Title: Ignition measuring device
Inventor: NEMEC DIETER
IPC: F02P17/02
Filed: 1984-01-12
Abstract: An ignition measuring device is proposed which serves to determine the speed of rotation and with which pulses can be generated for a stroboscope for measuring the adjustment angle. The ignition measuring device only requires one tap-off at the vehicle. By means of the adaptive behaviour of the measuring circuit, the ignition measuring device matches itself to the changing signal voltages in different types of vehicle and to the different operating conditions automatically so that adjustment is not necessary. <IMAGE>

Title: Process and apparatus for generating steam
Inventor: SPEICH PETER DIPL ING DR ING
IPC: C10J3/54
Filed: 1984-05-22
Abstract: The generation of steam 15 in a boiler 12 with the use of solid, fine-grained, carbon-containing materials 4 is carried out in such a manner that these materials are first gasified preferably in a high temperature Winkler reactor 1 and the resulting gas 11, predominantly composed of CO and H2, is conducted directly into the boiler 12 and burnt there. Gasification reactor 1 and boiler 12 are expediently combined to form one structural unit. The sulphur liberated from the carbon-containing materials 4 is already substantially bound in the gasification reactor 1 with the use of CaO or equivalent substances. The fact that gaseous fuel 11 is burnt in the boiler 12 facilitates the keeping of operating conditions which substantially avoid the formation of NOx. <IMAGE>

Title: Process and reactor for the catalytic conversion of hydrogen sulphide into elemental sulphur
Inventor: HEISEL MICHAEL DR
IPC: C01B17/04
Filed: 1984-08-01
Abstract: A process is described for the catalytic conversion, in the presence of sulphur dioxide, of hydrogen sulphide contained in a gas stream to give elemental sulphur. The gas stream is preheated and, for the purpose of conversion, passed over a catalyst bed. The vaporous sulphur produced is condensed out by cooling, and the gas stream freed of sulphur compounds is drawn off. So as to keep the pressure loss as low as possible and to reduce the investment and operating cost, while achieving a sulphur yield close to the theoretically possible value, it is proposed to pass the gas stream over a catalyst bed which is operated quasi-isothermally, to cool the catalyst bed internally by means of a cooling medium, to pass the gas stream into a condenser from below after the reaction, to cool the condenser internally and to draw off the sulphur precipitated on the condenser surface in liquid form.

Abstract: The invention relates to adjustable seating or lying furniture having a lying surface which is divided into a back part, a central part and a foot part, in which the back part is mounted so as to be rotatable about a pivot axis on a frame and is connected in an articulated manner to the central part by the end which is extended beyond the axis of rotation and faces said central part, in which the mutually facing ends of the central part and the foot part are connected to one another in an articulated manner, and in which the inclinations of the back part, central part and foot part are jointly and positively variable by shifting the body weight of the user when a fixing device has been released which retains the setting of the back part, central part and foot part. By means of a novel subdivision of the lying surface, a special coupling of the parts to one another and by means of a pivoting bearing of the foot part on an intermediate frame which is itself mounted so that it can be pivoted up on a basic frame, optimum adaptation of the lying surface to comfortable seating positions is achieved.

Title: Vertical adjusting device for a safety belt
Inventor: GERCKEN KARL
IPC: B60R22/20
Filed: 1985-02-15
Abstract: The invention relates to a continuous vertical belt adjusting device which comprises a few simple parts. A sliding block, to the upper end of which the deflector of the safety belt is screwed, moves in a C-shaped sliding rail, which is attached to the appropriate points of a motor vehicle body. In the rest position, the sliding block is clamped onto the rail by the tensile force of the belt and the diagonal load exerted by a spring. Toothings which are mounted on the sliding block and on the sliding rail help to make the locking secure. For adjustment, the sliding block is pressed backwards against the pressure of the spring at the deflection fitting or at a button or lever arranged above the deflection fitting. The sliding block is tipped over the cams, which are arranged opposite in a centred fashion, and is disengaged from the toothing. Displacement upwards and downwards is therefore possible. A sliding rod, which is enclosed by a sliding sleeve, can also serve as a sliding rail.

Patent DE-3508010-A1 (DE)
Inventor: BUCKENAUER GUENTER DIPL ING
IPC: E01D19/06
Filed: 1985-03-06
Abstract: The assembly for bridging over expansion joints comprises sealing band of elastic material which bridges over the joint, which sealing band, for being secured in upward open cavities, includes thickenings substantially filling up said cavities and extending in joint edge profiles at both sides in the longitudinal direction of the profile. Said thickenings include a support surface engaging in the inserted position with an appropriate pressing surface of the joint edge profile, said thickening being wedged in the cavity by means of a bulge formed thereon. Said thickening includes a nose formed thereon, which in the inserted position is pressed together in a manner that in the marginal portions of the cavity between the thickening and the joint edge profile there is a contact pressure. Thus it can be avoided that under the effect of any forces there opens a slit between the sealing band and the joint edge profile, whereinto moisture or dirt may make their way.
