Title: Four-stroke internal combustion engine
Inventor: ROESER WALTER
IPC: F02B53/08
Filed: 1984-10-25
Abstract: An intake chamber is provided for the air or fuel mixture intake and compression strokes and a working chamber with rotary pistons rotating in it for expansion and exhausting of the combustion gases. Both rotary pistons seated on a common engine shaft have an outer circumference such that piston circumference and piston chamber - in the intake chamber together with a slide valve - form variable working chambers during the piston rotation. The different piston chambers are connected to one another by way of a combustion chamber which can be closed off from both chambers in the proposed cycle. The firing point and point of complete lifting off of the free end of the swivel valve bearing on the outer circumference of the working piston during the rotation of the latter from a graduation provided in the closing position in the combustion chamber wall, which graduation is filled when lift-off occurs under spring pressure by a seal, are matched to one another. For air scavenging of the working chamber when fuel is injected into the compressed air, both rotary piston positions in relation to the precise adjustment for the start of compression and closure of the combustion chamber by the swivel valve are phase-offset against one another by a few degrees.

Title: Tread design for the pneumatic tyres of vehicles
Inventor: ROPPITSCH WOLFGANG
IPC: B60C11/04
Filed: 1984-11-20
Abstract: The invention relates to a tread design for the pneumatic tyres of vehicles, in particular for winter tyres, having at least four circumferential grooves, individual circumferential sections of which are offset with respect to one another, and having at least one continuous circumferential rib in the central area, having two rows of shoulder blocks and in each case at least one adjacent row of blocks with obliquely extending dividing grooves between the blocks. In order to improve the properties for all-year operation, it is proposed that the size of the offset of the individual circumferential groove sections correspond at maximum to twice the width of the grooves, that the circumferential length of the sections be approximately 40 to 60% of the circumferential length of the blocks, that the dividing grooves in the two rows of shoulder blocks extend at the same gradient and that the dividing grooves in the adjacent rows of blocks extend parallel to one another and at the same gradient but opposite those of the rows of shoulder blocks, and that, finally, offset sections, which are adjacent in the circumferential direction, of the circumferential grooves be connected by oblique grooves which extend over the lateral edges of the circumferential grooves.

Title: Process for thermally treating contaminated soil
Inventor: LORENZ KURT DR
IPC: F23G7/14
Filed: 1984-12-22
Abstract: The invention relates to a process for thermally treating soil which is contaminated with products preferably arising in the coking of coal, such as, for example, tarry, phenolic and oily constituents and heavy hydrocarbons. According to the proposal according to the invention, the contaminated soil is thermally treated by indirect heating and/or by direct addition of hot combustion gases and/or air with partial combustion of the decomposition products and of the Cfixed from the soil, and the resulting production gas is further burned at high temperatures to destroy any toxic constituents which may have formed. The use of a further combustion chamber has above all the advantage that any highly toxic gases, for example gases containing dioxin, are destroyed. <IMAGE>
Patent DE-3500967-A1 (DE)
Title: Process for sealing wooden floors
Inventor: SALLINGER HELMUT
IPC: E04F15/18
Filed: 1985-01-14
Abstract: The prior-art parquet-sealing methods, which required 2-4 coats, with in each case 120-200 g/m<2> using surface coaters or rollers, i.e. 240-800 g/m<2> altogether, are replaced by a single-coat sealing method, thus economising on intermediate drying times and a number of operations. This is possible by means of a sealant which, unlike the prior-art composition of sealants, even in a thick layer dries in a crack-free and bubble-free manner and is also rendered viscous to such an extent that it does not run into the recesses and joints of the parquet, but is still easy to spread. In order to make it possible to apply these unusually thick layers, a solvent-resistant foam in a clamp with a handle is used. Depending on the pore size of the foam used, the single-coat quantity applied is 250-350-450 g/m<2>, i.e. depending on the requirements for the parquet floor in terms of wear resistance and thickness of the surface. Even greater quantities of 450-1000 g/m<2> can be applied by means of a flexible toothed spatula.
Patent DE-3504518-A1 (DE)
Title: Method for the formation of the fuel-air mixture for a carburettor engine and mixture-forming device for this
IPC: F02M19/02
Filed: 1985-02-09
Abstract: A method for the formation of the fuel-air mixture for a carburettor engine, especially in a motor vehicle, according to the invention consists in aspiration of the engine combustion air through a porous membrane (64) impregnated with the fuel, the impregnation loss occurring on its outlet side due to vaporisation of the fuel being compensated for by metered supply of fresh fuel on the inlet side, adjustable according to the operating requirements. The process is performed by a mixture-forming device with a combustion-air intake duct (12) of preferably circular cross-section formed inside a housing (10), into which duct an atomiser nozzle (132, 134) opens in the middle of the cross-section. The nozzle (132, 134) is arranged on the air inlet side of a concertina-like expansion bellows (64) of absorbent textile material coaxial with the axis of the intake duct (12), which bellows tapers conically in the direction of the air flow through the intake duct (12) and is essentially sealed off from the housing (10) by its larger taper end. In this way, thorough mixing of the two mixture constituents in the form of gases is ensured under the performance and spatial conditions of a modern carburettor engine system and the efficiency of the system considerably increased. <IMAGE>

Title: Process for the phase and speed control of a direct-current motor drive
Inventor: APITZ SIEGFRIED
IPC: G11B15/467
Filed: 1985-05-17
Abstract: The motor drive for the head drum (1) and the tape transport (4, 6) of a video recorder is controlled phase-locked with a comparison oscillation by means of rotational speed sensors (7, 22) and phase comparison circuits (12, 25). For synchronising the head drum with the synchronising pulses of a synchronising pulse oscillation (IVSync), a phase measured value (Ap) for the phase error is generated from the phase comparison of the pulse oscillation of the angle of rotation sensor (9) of the head drum and the synchronising pulse oscillation and is stored. The error and the error progression of the phase, which is determined from the stored measured values, is used to determine or calculate the set value or set value progression of the comparison oscillation for the phase comparison circuit (12) of the direct-current motor (3) to be controlled. <IMAGE>

Patent DE-3522454-A1 (DE)
Title: Sauna
Inventor: OELLERS JOSEF
IPC: A61H33/06
Filed: 1985-06-22
Abstract: In a sauna with walls of wooden beams having a rectangular cross-section, at least one groove is provided in each beam surface and a tongue intended to engage in the groove is provided on the underside of the beam. The beams are held together by bores in tension rods gripping through the beam. In the angular connections necessary for the sauna walls the beams at the same heights each form a part-section of the angular connection. In order to avoid the beam projection hitherto required, the face ends of the beams of one wall abut the inner surfaces of the beams of the adjoining wall in order to provide an angular connection. At the same time, a peg with increasing cross-section toward the free peg end is provided on the face ends of each beam of the wall, the peg engaging in a recess provided on the end of the inner surfaces of the beam of the adjoining wall. Pegs and recesses are preferably designed so as to widen horizontally, resemble a dovetail and have a height corresponding to the beam thickness. In addition, a tension rod is inserted in each wall in the neighbourhood of the angular connection.

Title: Method and device for pneumatically conveying fluidised bulk materials
Inventor: STEINBERG HORST
IPC: B65G53/20
Filed: 1985-10-02
Abstract: According to the invention, which relates to a method for pneumatically conveying fluidised bulk materials, a fluidised bed is created in a conveyor line and maintained during the conveying motions by means of upwardly-directed compressed air currents. For this purpose, compressed air is blown from below into the conveyor line at specified distances over essentially the length of the conveyor line. To create the conveying motions, the fluidised bed is displaced in the conveying direction. By this means, satisfactory conveying over large conveying lengths with minimised internal consumption is achieved. <IMAGE>

Title: Additive for concrete and mortar mixtures and process for its manufacture
Inventor: HOERLING LUDWIG DR
IPC: C04B28/02
Filed: 1985-11-13
Abstract: The invention relates to an additive for hydraulic inorganic binder systems for the thinning, long-term thinning and improvement of early strength and contains water-insoluble substances, such as resins, bitumens, polycondensed synthetic resins and/or non-water soluble, solvent-dissolved, surfactants in an emulsifiable aqueous system, preferably of ligninsulphonates or sulphite waste liquors. The use of the relatively inexpensive sulphite waste liquors for the above purposes had previously failed due to a marked delay in cement hydration. According to the invention, this serious disadvantage can be eliminated by adding water-insoluble, solvent-dissolved surfactants and resins/plastics.
