Title: Method and means for producing perpetual motion with high power
Inventor: KALFAIAN MEGUER VARTAN
IPC: H01S3/09
Filed: 1983-08-26
Abstract: The perpetual static energies, as provided by the electron (self spin) and the permanent magnet (push and pull) are combined to form a dynamic function. Electrons emitted from a heated coil F are entrapped permanently within the central magnetic field of a cylindrical magnet M5. A second magnet M6, in opposite polarity to the poles of the electrons causes polar tilt, and precession. This precession radiates powerful electromagnetic field to a coil L between the cylindrical magnet and a vacuum chamber C - wound in a direction perpendicular to the polar axes of the electrons. Alternatively, the electromagnetic radiation is emitted as coherent light. The original source of electrons is shut off after entrappment. <IMAGE>

Title: Method for producing dried lump peat
Inventor: TOIVAKKA LAURRI HEIKKI ILMARI
IPC: E21C49/04
Filed: 1983-10-12
Abstract: A method for producing dried lump peat, wherein peat is detached from a bog and formed into lumps, whereafter the lumps are arranged on the surface of the bog and allowed to dry. The lumps are comparatively large, substantially disc-shaped pieces (1), for instance slices of uniform thickness the sides of which have an elliptical shape, and these lumps are arranged on the bog surface (2) so that their central axes are horizontal. About 5% of the surface area of the lumps will thus be in contact with the bog surface and the rest serves as drying surface on which the sun and wind may act. The drying on the bog surface preferably constitutes an initial drying phase, followed by final drying in a storage heap. <IMAGE>

Title: Process and apparatus for binding books
Inventor: EHLERMANN HANS DIETER
IPC: B42C9/02
Filed: 1983-11-10
Abstract: In a process and apparatus for binding books, upper (forward) portions of bookblocks in a vertical position with backs down are gripped by clamps on a conveyor for transporting the bookblocks through successive operating stations. At one operating station a rotating element dipping in a bath of adhesive applies adhesive in transverse strips to backs of bookblocks. At another operating station rollers apply adhesive to lower (rear) portions of first and last pages of the bookblocks. As front and back covers connected by a back are transported, inside up, along a path merging with the path along which said bookblocks are transported, adhesive is applied by rollers or spray heads to outer (forward) portions of the front and back covers. The covers are brought under respective bookblocks and lower (rear) portions of the bookblocks together with the covers are gripped between opposed pressing bars. As the bookblock with the cover thereon is further advanced in a guide channel, the clamp is removed and the book passes between pairs of opposed rollers which engage lower (rear) portions. Finally the books are pressed between opposed pressure plates before being discharged to a delivery system or to storage.

Abstract: A moving-coil motor (5) or a motor comprising a disc rotor is connected to a motion-converting gear (27, 28, 29) by way of a permanent-magnet across-the-wall clutch (22, 23). This converts the rotary movement of the motor (5) into a translatory movement of an auxiliary piston (30). The latter acts as a hydraulic actuating element for a cylindrical follower piston (38), which forms the valve slide. The permanent-magnet across-the-wall clutch is contained in a regulating circuit, which comprises the moving-coil motor (5) and a means for generating a signal representing the position of the valve slide, said means being provided on the auxiliary piston (30). <IMAGE>

Title: A rotary internal-combustion engine
Inventor: LEGGAT BERNARD CRAWSHAW
IPC: F01C1/356
Filed: 1984-01-17
Abstract: The engine comprises a multi- lobed rotor (RO) mounted for rotation (R) within a housing (H), working chambers (CH) being formed between the rotor and the housing by vanes (V), which are supported at their mid- portions by guides (VG) allowing the vanes to undergo both sliding and oscillating movements. The radially outer portions of the vanes are connected to rotor-driven crankshafts (CS), which rotate in the opposite direction to the rotor, the speed ratio being equal to the number of rotor lobes (GL) and (PL). The vanes are thus maintained in gas-tight sliding contact with the rotor periphery. Gases are admitted to, and expelled from, the working chambers via ports (IP) (EP) in the rotor and ports in housing side covers, Fig. 3. The rotor may have a generally square configuration, Figs. 6 and 7. <IMAGE>

IPC: G01R1/073
Filed: 1984-08-09
Abstract: An apparatus for testing electrical components by contacting them with a plurality of conducting probes and ascertaining the electrical condition between each or a selected number or pairs of such probes, information relating to the spatial disposition of the probes relative to a component being tested is generated by performing a mapping procedure wherein the probes are brought into contact with onre or more calibration surfaces, the or each surface being dividing into a multiplicity of conducting areas connected to test circuitry of the apparatus. When two calibration surfaces are used they have their respective multiplicities of conducting areas arranged to overlap to produce a larger multiplicity of discrete areas, each probe being so associated with one of said discrete areas. A pair of calibration surfaces can each be constituted by a single surface of a mapping board (25) divided into parallel strips (27) separated by insulating strips (28), and disposed in two positions angular spaced about 90 DEG . Board (25) can have location means (30a, 30b) for engagement with location pins on the apparatus. <IMAGE>

Title: Rangefinder
Inventor: WESTON GEORGE FREDERICK
IPC: G01S17/87
Filed: 1985-08-30
Abstract: A rangefinder operating by timing the return of a pulse of laser radiation by a target uses a photoconductive detector 7 in a mode which achieves adequate speed of response for close targets and improved signal to noise ratio for distant targets. The radiation receiving surface 8 of the detector is elongated in a direction transverse to the pulsed radiation beam direction 4, the surface being normal to the beam direction. The return pulse of radiation 13, 17 is focused at a Position along the elongated dimension of the detector in dependence on target range. The detector has an electrical contact 9, 10 at each end of the elongated dimension, and is operated in the sweep-out mode whereby ambipolar charge carriers generated at said position by return radiation are swept in the elongated direction 12 so that charge carriers produced by more distant targets travel greater distances along the detector, have a greater lifetime before recombining at one contact 9, and generate signal current contributing to said signal for a greater time. <IMAGE>
