Title: Contact pressure-producing device especially for vacuum switches in a single-row or double-row arrangement
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/666
Filed: 1987-08-07
Abstract: The invention relates to the improvement of the device for producing the contact pressure between the closed contacts (2, 3) especially in vacuum switch housings (1) in the case of an individual arrangement and a double-row or parallel circuit. To this end a leaf spring (20), for example, is arranged outside the mechanical system in order to transmit the drive force to the movable contact (3). As soon as the contacts touch during the switching-on process (connection process), a coupling rod (13), for example, of the force transmission system caulks itself against the leaf spring and stresses it. This coupling rod at the same time transmits the force of the stressed leaf spring to the movable contact, which then presses on the stationary contact and thus produces the contact pressure between the closed contacts. <IMAGE>

Title: Machine for removing the rind from bacon
Inventor: SCHILL HERMANN
IPC: A22C17/12
Filed: 1987-09-17
Abstract: A machine for removing the rind from bacon (Figure 2) has an automatic notching mechanism by means of which a blade (6) is displaced by the incoming material from which the rind has to be removed itself from a notching position to an operating position. A blade holder (5) which holds the blade (6) takes the form of a rocker and has, above the blade, a tilting bearing and a tilting stop at a distance from the latter. The blade holder (5) is mounted in holding arms (12) which are vertically adjustable and are acted upon by a force to bring about displacement of the blade to a drawing roller (4) which is situated beneath the latter. The blade holder is automatically held in the notching position by a restoring force which the blade is unloaded. Its blade plane is inclined downwards with respect to the feeding plane, towards the incoming material from which the rind is to be removed. The incoming material from which the rind is to be removed causes the blade holder (5) to tilt into the operating position. The blade holder is held by draw levers (22) approximately in the direction in which the material from which the rind is to be removed is transported, the said draw levers (22) extending in the notching position so that their longitudinal axes are at an angle to a line connecting the tilting bearing and the tilting stop. When this design is used, loading of the blade holder by incoming bacon causes stretching of the levers which are at an angle to one another, with simultaneous tilting of the blade holder (5) into the operating position. The draw levers (22) can be used to adjust the blade holder with respect to the angle of action of the blade. <IMAGE>

Title: Method of pause searching in cassette recorders
Inventor: FUELDNER FRIEDRICH
IPC: G11B27/22
Filed: 1987-09-30
Abstract: It is known to equip cassette recorders with a pause search, which detects a modulation pause during fast forwarding or rewinding when the tape is bearing slightly against the sound head and stops the tape drive, or automatically switches it to PLAY mode, if the pause in the modulation is longer than, for example, three seconds. The method is not satisfactory in cases of longer pauses or at the beginning of a tape after a long leader. A method which is improved according to the invention overcomes this drawback in that the pause searching device not only stops the tape drive in a known way when a pause occurs but also stops it when modulation occurs, on condition that at the start of the pause search there is no modulation on the tape and the modulation pause is longer than, for example, ten seconds, that is to say a new modulation section, for example a piece of music, begins after a lengthy pause or at the beginning of a tape after a long leader. The operating mode of the method is explained with reference to an example of a circuit.   Cassette recorders. <IMAGE>

Title: Valve with a pneumatic drive system
Inventor: BOESCH HUBERT
IPC: F16K31/163
Filed: 1987-12-12
Abstract: The invention relates to a valve with a pneumatic drive system, having a spring-loaded displaceable piston arranged in a cylinder housing and having a piston rod which is arranged on the piston and which is in engagement with a valve stem, at the end of which a gasket is arranged on a gasket seat in the manner of a valve. Valves of this type are known per se, high sealing forces being necessary in order to close the valve seat, along with drive systems of correspondingly large dimensions for the piston rod and valve stem. However, the greatest force is only ever required at the moment of closing of the valve seat, whereas only minor forces are needed for the remaining stroke, so that disadvantageously costly and complicated mechanical drive systems are employed, even though these are required only in the closing region of the valve. The object on which the invention is based is to employ a drive system of substantially smaller dimensions in the closing region of the valve, along with equally high sealing forces. To achieve the object, the invention provides for arranging a lever-transmitting member between the piston and the valve stem, a lower closing force generated by the piston being converted via the lever-transmitting member into a higher valve-closing force.

Title: Process for recording and reproducing information onto and from an optical disc of the phase-changing type
Inventor: KOMAKI TOSHIHIRO
IPC: G11B7/0045
Filed: 1988-08-08
Abstract: A description is given of a process for recording and reproducing data onto and from an overwritable optical disc of the phase-changing type, in which the data can be written in by a writing light beam, written data can be erased by an erasing light beam and written-in data can be read by a reading light beam. The initialising of the optical disc takes place in such a way that the width of the initialised region is greater than the diameter of the writing spot written onto the optical disc by the writing light beam. This can be accomplished either by the initialisation light beam acting on the optical disc with higher power than the reading and erasing light beams, or a light beam with the same power as the writing light beam may be used if the optical disc is moved during the initialising in such a way that the linear speed of the initialisation light spot on the disc is lower than that of the writing and erasing light spots on the same disc.
