IPC: H01H37/32
Filed: 1967-04-04
Abstract: 1,180,782. Valves. W. J. BUEHLER, and D. GOLDSTEIN. 4 April, 1967 [5 April, 1966], No. 15438/67. Heading F2V. [Also in Divisions C7 and G1] The temperature-responsive characteristic of a strip 16 of a nickel-titanium alloy is used to operate a valve 13 in a pipe 11 through which fluid such as that used in a fluid sprinkling system flows. The alloy strip which has been deformably twisted at a temperature below a critical temperature has one end secured to the valve stem 14 whilst the other end is secured to a block 17, a key 18 of which engages a keyway 21 in a boss 22 to prevent rotation of the block. On heating the alloy above its critical temperature, the valve is caused to rotate as the alloy strip returns to its undeformed state, thereby permitting the fluid to flow through the pipe.

Abstract: 1461513 Grinding NEHEZIPARI MUSZAKI EGYETEM 8 April 1974 [24 April 1973] 15474/74 Heading B3D A machine for grinding workpieces of non- circular cross-sections comprises a powerdriven grinding disc mounted on a bed, two headstocks having synchronously driven and axially aligned spindles 27, 28 having at their free ends centres 25, 26 for holding a workpiece 1 with adjustable eccentricity, the workpiece being arranged to be set in rotation by an entrainment device 29 and the ratio between the r.p.m. of the device 29 and the spindles depends on the number of sides of the crosssectional profile to be ground, the difference between the actual and the desired ground profiles caused by the different diameters of grinding discs being equalized by a correction device 35 built into the drive of the entrainment device or in the spindle coupled thereto. The device 35, in use, causes a periodic displacement between the planatery movement of the workpiece axis and the rotational movement of the workpiece, the number of periods per workpiece rotation being twice as great as the number of profile angles or sides. The workpiece 1, Fig. 1 is mounted between the centres 25, 26 of adjustable eccentricity on the spindles 27, 28, respectively, the spindles being driven at equal rotation by gearing 30, . . . 33 from a shaft 34 driven by a belt drive 38, 39 from a D.C. motor 40. The workpiece is rotated on the centres 25, 26 by the device 29 also driven by gearing 36, 37 from the shaft 34. To compensate for the fact that the grinding wheel does not have a line contact with the workpiece and that the contact between the wheel and workpiece moves transversely from the line joining the axes of the wheel and workpiece during rotation of the workpiece, correcting device 35 is inserted between shaft 34 and the gear 36 to periodically vary the ratio of the angular velocities of the rotation of the workpiece and the rotation of the spindles 27, 28. The correcting device may consist of an eccentric 47, Fig. 4, on an arm pivotably supported in a disc 46 on a tubular shaft 45 in the drive to the device 29, the arm bearing against an adjustable stationary body 51. The eccentric is coupled to a disc 48 which can be connected to the shaft 34 by a dog clutch 49. In another embodiment, the correcting device of a thin walled tube 62, Fig. 7, which can be deformed by adjustable shoes 65 carried by a stationary ring 66, the tube being engaged by a follower arrangement 70 which transmits both the continuous rotation and the variation in the angular velocity. In a further embodiment, the variation is effected by periodic relative axial movement between a pair of helical gears.

Filed: 1941-12-08
Abstract: 578,154. Projectile fuzes. FREEMAN, C. T. Dec. 8, 1941, No. 15798. [Class 9 (i)] A striker 3 carried by a dished metal diaphragm 4 is normally restrained in the position shown by a collar 7 which is urged inwardly by a spring 8 but is restrained by a plunger 9. As the bomb falls, wind-vanes 12 rotate and unscrew a cap 11 which falls away, thus allowing a spring 10 to urge outwardly the plunger 9. The fuze is thereby armed. The diaphragm is held in place and protected by a screwed plug 5 apertured at 6 to admit air to the convex side of the diaphragm. While the projectile is falling unobstructed, the air pressure is insufficient to cause reversal of the diaphragm, but when the projectile is exposed to a sudden rise in air pressure, as by approaching an obstruction or by coming into range of blast created by another exploding projectile, the diaphragm reverses and causes the striker 3 to strike the detonator 16. The cap 11 is prevented from accidentally unscrewing during transport &c. by a pin 15 paseing through a hole in the cap into a radial bore in the fuze body, this pin being attached' to a clip 13 which embraces the cap and whose ends may be wired together. An eye 14 on the clip may be attached to a fuze-setting control link, so that the bomb may be dropped " safe " or " live." When the bomb is dropped " live," the control link retains the clip.
