Abstract: 1,116,955. Piezo-electric resonators. STANDARD TELEPHONE & CABLES Ltd. 10 Sept., 1965, No. 38719/65. Heading H1E. In order to reduce the activity of unwanted modes of vibration, the electric field of a piezoelectric crystal resonator is arranged to lie at an angle to the plane of symmetry passing through the resonator between the electrodes. The invention may be applied to a doublerotated Y-cut quartz resonator operating in a thickness mode. Such a cut is obtained by rotating the original Y-cut prism first through an angle 0 about the Z axis, then through an angle # about X<SP>1</SP> (the modified X axis). Good temperature characteristics are obtained for values of # and # equal respectively to - 34‹30' and 15‹, or respectively + 35‹ and 20‹. As shown, the resonator is in the form of a convex disc and carries electrodes 5, 6 spaced apart in the direction of the X<SP>11</SP> axis so as to determine a field having the direction 20 lying at an angle to the plane of symmetry containing the axes X<SP>11</SP>, Z<SP>11</SP>. In a modification, the electrodes are spaced from the surface of the resonator. In another modification, the electrodes have central, circular, overlapping portions connected to sectorial portions spaced in the direction of the X<SP>11</SP> axis.

Title: An improved process and apparatus for the manufacture of copper sulphate
IPC: C01G3/10
Filed: 1956-12-20
Abstract: <PICT:0796578/III/1> Copper sulphate is prepared by dissolving granulated copper in hot dilute sulphuric acid in the presence of air by passing the acid and air continuously upwards through a heap of copper granules in the reaction vessel, and withdrawing the sulphate solution and sludge of impurities from above the heap of granules. The air is advantageously introduced at such a pressure that it fills the entire cross-section of the reaction vessel and causes the granules to grind against one another, which results in the surface being constantly freed of sludge and so exposed to the action of the acid and air.  In the preferred form of the apparatus the granules f are on a grid c, and acid is admitted at 6, and air at d.  The solution and sludge are withdrawn at h.

Title: Improvements in and relating to winches
IPC: B66D1/02
Filed: 1957-12-16
Abstract: 840,532. Hand winches. TREWHELLA BROS. PROPRIETARY Ltd., and TREWHELLA, B. H. Dec. 16, 1957, No. 39108/57. Class 78 (5). The winding drum 3 of a venetian blind is driven directly by handle 7 and at the same time is braked by spring 12. The spring is secured at one end to casing 1 fixed on a wall, and at the other end engages frictionally internal wall 14 of the drum. The braking effect is sufficient to prevent reverse rotation of the drum under the load of the blind, but not sufficient to prevent rotation by means of the handle. The load therefore on the end may be raised easily because the friction of the spring is diminished and when the winding up is stopped the full effect of the spring comes into play to prevent the load falling. The said cord wound on the drum 3 is passed through aperture 4 and secured by clamping- plate 5.

Convention date, July 27, 1932. Divided on 406,654, under which a Specification was laid open to inspection under Sect. 91 of the Acts, July 28, 1932. [Class 106 (i).] Transfer mechanism comprises ratchets and tripping means on the totalizer wheels, bellcrank levers co-operating with the tripping means, studs on the bell-crank levers, oscillating arms, levers on the arms co-operating with the studs, pawls on the arms positioned by the levers into such a position that they can effect a transfer when the oscillating arms are moved, the bell-crank levers having restoring surfaces with which the tripping means co-operate to restore any transfer mechanisms inadvertently tripped by an overthrow of the totalizer wheels. Totalizer-engaging mechanism.-The totalizer 152 is mounted on a frame 150 pivoted at 151 and rocked into engagement with the actuating gears 138 by cams 156 on a shaft 155. The cams engage fixed pins 157 and so rock the frame 150 when the shaft 155 is rotated by a pinion 154 and sector 153 actuated by a link 164. The gears 138 are aligned by a bail 145 actuated by a link 236. Transer-mechanism.-Ratchet wheels 182, Fig. 2, are secured to the totalizer wheels and are normally locked by pawls 183 pivoted to oscillating arms 185 pivoted at 151. When the totalizer is moved into engaging position, the arms 185 are rocked by cams 188 on the shaft 155 engaging studs 186 on the said arms, the pawls 183 thus being withdrawn from the ratchet wheels 182. When a numeral wheel passes through zero a cam 191, Fig. 9, on the wheel rocks a bell-crank lever 194 having a stud 196 engaging a fork 198, Fig. 2, in a lever 200 pivoted on the next higher arm 185. The lever 200 has its end 201 engaged with the pawl 183, so that the pawl is rocked into such a position that, when the arms 185 are restored seriatim by the cams 188, they effect transfer and also restore themselves and the levers 200 and bell-crank levers 194. The levers 200 are held by detents 204 and the ratchet wheels 182 by detents 209. Overthrow-preventing.-If the totalizer wheels are overthrown during actuation and then returned to correct position by the aligning bar 145, the pivoted member 194 is rocked by the cam 191 but is restored during the aligning movement by a second cam 215, Fig. 9, on the totalizer wheel. Specifications 285,500, 286,314, 318,466, [all in Class 106 (i)], and 406,654 are referred to.
