Title: Power Transmission Device
IPC: F16H3/00
Filed: 1979-11-29
Abstract: The object of the invention is to produce a power transmission device of simple construction in which no selectively operable movable components are required to render effective either of the desired gear ratios and which does not use externally powered clutches or brakes. This is achieved by means of a gear box which, when its driving shaft is rotated in one direction, operates at one gear ratio; and, when its driving shaft is rotated in the opposite direction operates at a different gear ratio. The output shaft rotates in the same direction in each case. A motor M drives an input pinion 6 which meshes with two pinions 11 and 8 connected through respective oppositely acting one-way clutches 10, 12 to shafts 13 and 7. Rotation of the shaft 5 in direction C causes output shaft 7 to rotate at one speed in direction A. Rotation of shaft 5 in direction B produces rotation of the shaft 7 at a different speed but in the same direction. <IMAGE>

Patent GB-2051658-A (GB)
Title: Method for producing sheet molding compound
IPC: C08J5/04
Filed: 1978-12-29
Abstract: The invention relates to a method for forming a sheet molding compound. The sheet molding compound is linearly advanced. A movable upper surface formed by a belt passing around a series of driven rollers is adapted to contact the upper surface of the sheet molding compound. The belt is held in biased relationship to the sheet molding compound. In one arrangement of the invention, the sheet molding compound is caused to undulate vertically while retained in compression to induce one form of shear effect. In still another embodiment, as the molding compound is passed in vertically undulating fashion between compressing mesh belts, one of the belts is driven at a fixed rate, while the opposite is driven at rates oscillating above and below the fixed rate.

Title: Locking mechanism
Inventor: LOWES ROBERT WILLIAM RADCLIFFE
IPC: E05B65/00
Filed: 1982-04-13
Abstract: The invention provides a locking mechanism for a safe, including two bolts (3) and (4), controlled by a lock (14), the arrangement being such that if the lock is removed, the two bolts are automatically moved into the locked position. An operating member (7) is slidable on each of the bolts and a helical spring (9) is located between a collar (8) on the operating member and a shoulder (10) on the bolt. The two collars are slidable in a fixed member (11) and the two springs (9) are normally compressed by means of a connecting strip (12) secured to the latch member of the lock (14) by means of a screw (15). If an attempt is made to enter the safe by removing the lock (14), the connecting strip (13) will be removed with it. As a result, the springs (9) will urge the bolts (3) and (4) into the locked position. Deformed portions at the lower end of the springs (9) will enter annular recesses in the bolts to prevent them from being forced out of the locked position. <IMAGE>
