IPC: B27L7/06
Filed: 1991-09-06
Abstract: Form 24 (s.s. 21, 31, 34, & 142) Abstract It is a tool for splitting wood, specifically a hollow steel sheath fabricated in the exact configuration of a plastic wedge commonly used in the logging industry. To use it, a plastic wedge is inserted into the metal sheath and both are simultaneously driven into the wood by hammer force striking the plastic wedge.                     Specification This invention relates to a manually driven wedge used for splitting wood.   The plastic only wedges now in use are very frail relative to the forces they are subjected to, and therefore have a limited lifespan. The plastic only wedges are also somewhat flexible which often causes them to bounce forcibly out of their intended direction.  This makes them hazardous to the workman, and the plastic wedges cover enough distance to make retrieval difficult. An all-steel wedge is dangerous because of steel particles dislodged by the force of steel (i.e. hammer) on steel wedge. Further, the weight of all-steel wedges make them impractical to handle and carry.

IPC: B60J7/06
Filed: 1991-12-12
Abstract: In a folding roof for an automobile, a front hood bar is moved  by  entraining  elements  driven  by  cables,  which entraining elements can travel in curved transitions of lateral guide rails and simultaneously in curved control slits of control plates, slidable transversely on the front hood bar.  The control slits run partly ascending towards the  closure  position,  in  order  to  create  a  downward displacement of the front hood bar as the roof is closed and an upward displacement of the hood bar as the roof is opened.   The closing of the roof takes place with a continually decreasing speed of movement and continually increasing closure force, without any noticeable feedback effect upon the actuating force to be applied.

Filed: 1992-04-23
Abstract: A method and apparatus are described for verifying handwritten, human signatures, and for permitting access to a system if such a signature is accepted. In an initializing stage, an authorized entrant submits a sample of multiple signatures (110). A first reference signature is selected from the sample (150), and a second reference signature is constructed by averaging over the sample (180). When a subsequent, prospective entrant submits a signature, a dynamic mismatch is calculated with respect to the first reference signature (220), and a shape mismatch is calculated with respect to the second reference signature (240). The signature is accepted if it satisfies a predetermined criterion that refers to the dynamic and shape mismatch values (250, 260).

Abstract: The invention relates to an intaglio printing machine having a plate cylinder, and an impression cylinder which is equipped with an actuator for engagement and disengagement and can be adjusted by means of this actuator between an operating position resting on the plate cylinder and a position of rest removed from the latter. A wiping device has a wiping cylinder which interacts with the plate cylinder, and likewise can be adjusted by means of an actuator between an operating position, in which it rests on the plate cylinder with predetermined pressure, and a position of rest removed from the plate cylinder. The wiping cylinder is mounted in eccentric bushes and can be coarsely adjusted by means of hydraulic cylinders, by which the eccentric. bushes can be rotated, between its operating position resting on the plate cylinder and a position of rest removed from the latter. Additionally, a fine adjustment is provided, by which the change in spacing between the axles of the plate cylinder and the wiping cylinder, as a result of deflection of the plate cylinder occurring during the engagement of the impression cylinder, can be compensated. For this purpose, the hydraulic cylinders are each attached to a worm wheel which can be rotated by a worm spindle. Providing the fine adjustment of the worm spindle is a stepping motor, which is adjusted simultaneously with the engagement and disengagement of the impression cylinder in each case by a preselectable amount in either direction.

IPC: G11B11/105
Filed: 1992-11-04
Abstract: A magneto-optical disk, which possesses a disc-shaped substrate and a recording layer composed of a perpendicular magnetization film that is formed on the substrate, has an area wherein magnetic domains having an upward magnetization and magnetic domains having a downward magnetization are alternately aligned along at least one circuit of the disk. The area is formed on the recording layer.   The length of the magnetic domains having the upward magnetization are virtually equal to the length of the magnetic domains having the downward magnetization.  Another form of the invention is a reproducing method in which, when information is reproduced by projecting a light beam onto the magneto-optical recording disk, the intensity of the light beam is adjusted so as to maximize the amplitude of a reproduced signal that is obtained from the area. With the above arrangement, a high-quality reproduced signal can be obtained independent of the characteristics of individual magneto-optical disks.

Title: Method of making a frequency doubling structure in an optically non-linear medium and a device for doubling frequencies
Inventor: HORSTHUIS WINFRIED H G
IPC: G02F1/361
Filed: 1992-12-18
Abstract: ABSTRACT OF THE DISCLOSURE       A frequency doubling structure composed of an alternatingly poled NLO polymer is incorporated into an optically non-linear (NLO) polymeric material.  This structure is made by forming a layer of a first NLO polymer, partially removing it by etching after it has been poled with the aid of a first electric field or not, such that a grating structure is formed composed of etched grooves in the polymer, and applying a layer of a second NLO polymer, such that the etched grooves are backfilled, after which the resulting alternating structure of the two NLO polymers is subjected either to a second electric field oppositely directed to the first one, or in the case of poling of the first polymer not yet having taken place, to two oppositely directed electric fields in succession.  The second electric field is applied at a temperature which will not affect the poling of one NLO polymer effected by the first electric field.  Further, a frequency doubler comprising an alternating structure of oppositely poled NLO polymer is provided.
