Title: Removal of transient exothermic-combustible substances from contaminated soil
IPC: F23G7/06
Filed: 1993-01-20
Abstract: In a process and electrically-powered assembly to clean soil contaminated with transient exothermic-combustible substances, the novelty is that: the assembly has an air outlet which injects cleaning air into the contaminated soil, that air bearing contaminated air from the soil is removed by a suction pump that the contaminated air is delivered to a combustion engine which is linked to an electrical generator and that the electrical energy generated is used to power the electrically-powered assembly.The energy content of the contaminated air removed from the soil is regulated by the addition of fuel and/or oxygen depending upon the requirements of the engine in use.

Title: Circuit arrangement for multiplication of elements in a finite Galois field (2<8>)
Inventor: MESTER ROLAND DIPL ING
IPC: G06F7/72
Filed: 1993-02-09
Abstract: A Galois field multiplier for a finite Galois field GF (2<8>) is proposed. In it, Galois field elements are fed on first parallel lines (A0 to A7) as a first factor to a first EXOR network (101 to 127). Intermediate results (Enn), which are output at the output of the EXOR network (101 to 127), are ANDed in a one-stage AND network (x00 to x77) with second Galois field factors which are transmitted on second lines (B0 to B7). The products of the input elements can be taken from third lines (P0 to P7) in a three-stage EXOR network (201 to 207) which is connected in series. <IMAGE>

Title: Fuel injection pump for internal combustion engines
Inventor: GUENTERT JOSEF
IPC: F02M59/26
Filed: 1993-03-31
Abstract: Fuel injection pump for internal combustion engines with a pump piston (1) guided in a cylinder sleeve (5) and there defining a pump working chamber (9), which piston interacts with a control aperture (11) in the wall of the cylinder sleeve (5) in order to control the high pressure feed. For controlling the start of delivery the pump piston (1) on its front face (7) has three control edges (14, 18, 20), staggered in the piston's longitudinal direction, a zero delivery area being provided between the first control edge (14) controlling a very early start of delivery and the other control edges (18, 20). The end of delivery is controlled by way of an inclined control recess (22) in the piston circumferential surface connected to the pump working chamber (9), which recess is formed from two inclined grooves (24, 28), offset in relation to one another, the edges of which on the pump working chamber side form a first inclined control edge (26) and a second inclined control edge (30), separated from the former by a step (32), the distance between the second inclined control edge (30) and the second front face control edge (18) arranged above the former being less in the area of the step (32) than the diameter of the control aperture (11), so that a zero delivery range is formed without severely limiting the control travel range on the pump piston (1). <IMAGE>

Filed: 1993-04-30
Abstract: The invention relates to a drive operating on one side or two sides, especially for use in adjusting devices of motor vehicles, using at least one wrap spring acting on a shaft and a drive lever which makes possible the transmission of force when pivoted away from its zero-point position. The adjusting drive is characterised in that the drive lever is connected in a positive manner to a force-transmitting switching element which, during an actuation of the drive lever, is pivoted about an axis, the switching element switching the wrap spring which is arranged on a shaft or the like, specifically in such a way that on pivoting the drive lever away from the zero-point position the wrap spring is biased using the outer contour of the shaft, while this wrap spring is opened on pivoting the drive lever in the direction of the zero-point position and permits a relative movement towards the shaft. <IMAGE>

Patent DE-4408445-A1 (DE)
Inventor: LIEBRAM UDO
IPC: B29C69/00
Filed: 1994-03-12
Abstract: In a process for producing a shell of heat-formable plastic, a plate-like section of the plastic material (40) to be processed is conveyed on a vertical web (21) through at least two heating stages (45) behind each other in the direction of travel (21, 24) downwards to a deep-drawing station (16, 24) and then deep-drawn.

Title: Safety foot control linkage for a motor vehicle
Inventor: DOELLNER GERNOT
IPC: B60R21/09
Filed: 1994-03-18
Abstract: The invention relates to a safety foot control linkage for passenger motor vehicles with a bearing bracket (4), serving for the swivelling articulation of at least one pedal (2) acting on a pushrod (14), which bracket is fixed on a wall area (5) of the splash wall or transverse wall of the vehicle being discernibly deformed into the passenger compartment (15) in the event of a vehicle frontal impact. In order to further reduce the risk of injury to the driver in the foot area in the event of a vehicle frontal impact, the pedal axis (3) of the pedal (2) is mounted in the bearing bracket (4) in an abutment (7) which, although it conventionally supports the reaction forces occurring in operational actuation of the pedal (2), through interaction with a release mechanism (9) automatically releases the pedal axis (3) in the event of a vehicle frontal impact, specifically in such a way that the pedal (2) is capable of swivelling essentially without resistance with its pedal axis (3) towards the cross member (6) out of the abutment (7) and with its lower free end towards the wall area (5) carrying the bearing bracket (4). At the same time, the release mechanism (9) is supported on a cross member (6) fixed to the body, which member runs at an interval from the wall area (5) on the passenger compartment side and maintains its spatial position even in the event of a frontal impact. <IMAGE>

IPC: H04R3/04
Filed: 1994-03-26
Abstract: The transducer e.g. loudspeaker has an electrical input function imposed upon it by an electronic manipulator. This function is superimposed on the intrinsic function of the transducer, and the combination is compared with the unmodified input function.

Abstract: A measuring device for measuring the area of a closed curve is disclosed. A member is provided which moves freely along the centre of a vertical shaft in a condition in which it is fixed in the base. In order to measure the length, an actuating element slides in the horizontal direction through the member and is supported therein. A following (tracking) means for following the line of the figure engages with the front end of the actuating element. An angle of rotation of the member is measured in units of 0.072 DEG  by an angle index plate which is fastened on a fixed shaft, while a moving distance is measured in units of 0.01 mm by a photosensor which is included in the member. While the following means is following the line of the figure on the basis of the central point of the member, the area of the figure is subdivided into a triangle whose one base is connected to that of the neighbouring triangle, which has the same angle. The device for measuring two bases of the triangle and the angle it encloses employs a sine rule (law). <IMAGE>
