Patent DE-3229108-A1 (DE)
Title: Thermal drive system for motor vehicles
Inventor: EDER FRANZ X PROF DR ING
IPC: F02G3/02
Filed: 1982-08-04
Abstract: The invention consists of a cylinder filled with compressed gas and having a periodically moved displacer piston, of a thermal regenerator and two heat exchangers inserted between the cylinder head and a lower working volume. Heating energy is supplied in the cylinder head via one of these heat exchangers by burning liquid or gaseous fuel at a high temperature, while the lower working space is connected to two pressure vessels via two non-return valves opening in opposite directions. During the periodic piston movement produced by a low-power driving motor, the gas mass is forced into the hot cylinder head at bottom dead centre, i.e. a higher pressure of the working gas is produced and part of it is forced into the high-pressure vessel. At top dead centre of the displacement piston, the working pressure in the overall system falls and a certain quantity of gas flows out of the low-pressure vessel into the lower working space. In the steady condition, two different pressure levels are built up in the two gas buffers, the difference between them being used to perform mechanical work in an expansion motor connected between them. As the flow rate rises, i.e. as the rotational speed increases, the effective pressure difference decreases; with the expansion machine at a standstill, it and hence also the torque are at a maximum. This device can be used for the drive of vehicles, by reversing the motors the combustion energy being used to pump up the high-pressure vessel, i.e. for energy accumulation.

Patent DE-3234821-A1 (DE)
Title: Folding machine
Inventor: HAEFNER WALTER DIPL ING
IPC: B65H45/12
Filed: 1982-09-20
Abstract: A folding machine for folding in particular large-format carton blanks consisting of heavy corrugated or solid fibreboard comprises, mounted in a frame, supports which support the previously aligned blank and serve as an abutment during folding, these supports being arranged alongside and parallel to the edges to be folded. To hold down the blank during folding, folding bars are provided on the frame which run parallel to the folding edges, folding arms mounted swivellably in the frame being used to bend over the lateral parts of the blank, which is situated between the folding bars and the supports, through approximately 180 DEG  towards one another along the folding lines. To reliably prevent possible displacement of the blank during folding, the folding bars are assigned frame-anchored pressing means by means of which the folding bars are pressed onto the blank and hence the blank is pressed onto the supports, so that the blank is clamped firmly between the folding bars and the supports. To eliminate additional tolerances in the folding, the folding station is also provided with a post-forming means which serves for calibrating the folded edge and also as a lateral guide when the folded blanks are transported further.
Patent DE-3248783-A1 (DE)
Title: Composite plate
Inventor: WAHL WOLFGANG DR ING
IPC: B32B7/022
Filed: 1982-12-31
Abstract: A composite plate for large surface-area wear protection is described, in which a basic plate of relatively soft, tough material is soldered on at least one wear plate of hard, brittle cast material. In this, the solder layer does not bond the basic plate to the wear plate over its whole surface; rather, a multiplicity of exposed points remain, which are statistically uniformly distributed over the overlapping surface of the basic plate and wear plate and the average surface area of which exceeds 2 cm<2>. The total surface area of the exposed points may amount to up to 60% of the overlapping surface area between the base plate and wear plate. Composite plates of this kind can be particularly economically produced without detracting from their use, in particular without the risk that individual fragments are released with the fracture of the wear plate (Figure 1). <IMAGE>

Title: Tail unit for a kinetic-energy projectile
Inventor: REUSCH RUDOLF
IPC: F42B10/14
Filed: 1983-02-12
Abstract: A kinetic-energy projectile 10 carries a tail unit arranged at the rear and consisting of swing-out tail-unit wings 40 which, in the state of rest, are mounted rotatably about axles 41 arranged in recesses of the projectile body. The rear part of the projectile body comprises a centrally axial bore 42, in which a pot-shaped slide 44 loaded by a compression spring 43 is mounted slidably. After a holding ring 46 has been pressed into a wedge-shaped annularly continuous groove, the slide 44 initially retained by the holding ring, with the compression spring 43 compressed, is violently released and strikes with its outer bottom face against the end pieces adjacent to the rotary axle 41, of the tail-unit wings 40, with the result that these are swung out. <IMAGE>
Patent DE-3311228-A1 (DE)
Title: Method and device for gripping and guiding an elongate bone
Inventor: REIFENHAEUSER TONI
IPC: A22C17/02
Filed: 1983-03-28
Abstract: An elongate bone (10) is pushed by an advance piston (3) coaxially through a groove (1) and forced against a plate (13) designed as a stop member. Under the pressure of the advance piston (3) the plate (13) yields to an adjustable extent and finally actuates a switching element which closes a pair of forceps (7) located in the region of the groove end (2). Due to movement of the bone (10) essentially at right angles to its longitudinal extension the bone (10) moves from the stop region of the plate (13) into the effective region of a saw (15) which severs a piece of bone (16) projecting above the groove end (2) from the bone (10). After an opening movement of the pair of forceps (7) the advance piston (3) again causes advance of the bone (10) with repetition of the above-described sequence of movements until the bone (10) finally is reduced to a residual piece of bone (19), whereupon the residual piece of bone is removed from the groove (1) when the pair of forceps (7) are open. <IMAGE>

Patent DE-3334060-A1 (DE)
Title: Clamp for clamping workpieces
Inventor: VOGELBRUCH WILHELM
IPC: B25B5/10
Filed: 1983-09-21
Abstract: The invention deals with a clamp for clamping workpieces, with a clamping strap through which a clamping screw which can be anchored on the mounting surface passes approximately concentrically. The clamping-jaw section of the clamping strap has at least one bore for the axially adjustable location of at least one pressure screw. The other clamping-strap section contains a bore, preferably of the same size, for the axially adjustable location of a set screw. Both this set screw and the clamping screw can be supported via a spatially movable floating nut. At the shank end, the at least one pressure screw can have a pressure piece mounted in a spatially movable manner. A clamp designed in this way can be used universally and, on account of the many possible spatial positions, permits an optimum distribution of the clamping forces even on complicated workpieces.

Patent DE-3403652-A1 (DE)
Title: Method and device for adaptive steam cooling
Inventor: HOOF YVAN VAN DIPL ING
IPC: F22G5/12
Filed: 1984-02-02
Abstract: In a method for adaptive steam cooling, superheated steam conducted in a steam line 3 is cooled essentially by injecting condensate via an injection nozzle 4 until the saturation temperature is almost reached. The quantity of the condensate to be injected is regulated by comparing the actual value of the temperature of the cooled steam measured using a temperature sensor 7 to a desired temperature value prescribed in an automatic temperature control 8. In order to be able in a simple and economic way reliably to avoid partial condensation in the cooled steam, the desired temperature value to be prescribed for regulating the quantity of condensate is set as a function of the pressure of the cooled steam measured by a pressure sensor 10 is set to a value above the saturation temperature occurring at said pressure. For this purpose, the pressure sensor 10 is connected, if necessary via a measuring converter 10' to a computing device 11 which assigns a specific desired temperature value to each measured pressure. The computing device 11 is, for its part, operationally connected to the automatic temperature control 8 for the purpose of inputting the desired temperature value determined as a function of pressure. <IMAGE>

Title: Swivel device for laboratory glass devices in laboratory centrifuges
Inventor: REDEKER JOERG
IPC: B04B5/04
Filed: 1984-02-21
Abstract: A support (2) in which at least one rocker (3) is swivellably mounted is mounted on a base plate (1) to be held in a centrifuge. The said rocker (3) is provided with receptacles (4) for laboratory glass devices (5) and is supported on the leg of the rocker by a helical spring (7), which leg, as a result of displacement of the centre of gravity, is the heavier leg (3b) so that the lighter leg (3a) is located in the lower limit position. Electrical contacts (9) for a switching device of the centrifuge motor are associated with the two ends of the rocker. At a sufficiently high speed of revolution of the centrifuge, the heavier leg (3) overcomes the spring force as a result of the centrifugal force and moves into the contact position which switches off the motor. As a result of the subsequent dropping off of the centrifugal force, the spring presses the rocker back into the opposite contact position which switches on the motor again. <IMAGE>

Filed: 1984-05-28
Abstract: Method of counting particles of seed, fertilizer, and other materials employed in agriculture acoustically. The particles to be counted are conveyed against an impact plate in such a way as to start it oscillating, generating electric signals that are processed to determine the number of particles. In order to count the exact number of individual particles passing a test point with relatively high precision and by acoustical means, at least one definite oscillation amplitude that is characteristic of the impact of one particle is determined and stored and a comparable actual oscillation amplitude is determined as the particles strike against the impact plate, is compared with the stored oscillation amplitude, and, if it is shorter than the characteristic amplitude, one particle counted, or, if it is higher than the characteristic amplitude, the inference made that another particle has struck the plate.

Title: Safety belt switch for the driver's seat in a passenger car
Inventor: LAMBEY GEORG
IPC: B60R22/48
Filed: 1984-06-12
Abstract: The safety belt switch can be mounted as an attachment to the lock on the safety belt, but its incorporation into the lock in every new vehicle would be the best policy. In the case of incorporation in new vehicles, an enlargement of the safety belt lock by about 2 mm would be advisable, so that the plug of the belt of the front passenger seat cannot be used. Much would be gained for little cost in this way. An increase of only 1% in the number of people who fasten their safety belts would considerably reduce the number of deaths and severe injuries. Most drivers who do not fasten their safety belts fail to do so out of forgetfulness. This would be made impossible by the safety belt switch.
