Abstract: 1,019,518. Overload devices for jib cranes. E. K. COLE Ltd. Nov. 25, 1963 [Nov. 23, 1962], No. 44307/62. Heading B8B.  To measure the tilting moment about a point F, Fig. 1, in a jib-crane, strain gauges are attached to mounting blocks A, C and their outputs fed to a bridge circuit, Fig. 2, not shown. Potentiometers in the circuit provide voltages proportional to distances z, y so that the total output, which may be used to operate a warning signal, is proportional to the overturning moment. Fig. 3 shows an arrangement in which the vector sum of the moment applied by a hoist rope b, a derricking rope d and a jib j contribute to the total tilting moment. Strain gauges are provided at ha, da, ja. Each gauge is as shown in Fig. 4 in which gauges K, L, M, N are bonded into an axle a so that when a force is applied in direction f, K and L will decrease and M and N will increase in resistance. When a force is applied in direction X the reverse occurs. By orienting these gauges and connecting them in a bridge the output will be proportional to force X. The sum of the moments from each group of gauges about a point F is obtained from a further bridge circuit. Any transducer with an output proportional to the deforming force may be employed.

Title: Improvements in electro-mechanical oscillatory devices
Inventor: SMITH FRANK GERALD
IPC: H04L25/46
Filed: 1962-11-28
Abstract: 949,821. Telegraphy. CREED & CO. Ltd. Nov. 28, 1962, No. 45004/62. Heading H4P. An electro-mechanical device for regenerating or re-arranging the electrical pulses in a telegraph code combination signal, for example a fire-element signal, comprises two parallel and closely adjacent plates 3 and 7 mounted by means of arms 2 and 6 for oscillation about torsion bars 1 and 5. The plates are counterbalanced by weights 4 and 8 and each has a slot 9, 10, which extends radially with respect to the support. The slots are at right-angles and so positioned that they intersect. The point of intersection, when the plates are allowed to oscillate, traces out a closed figure and, where the frequency and amplitude of oscillation is the same but the phase relationship a quadrature one, the figure is a circle. Photoelectric devices may be arranged to give output pulses when the intersection reaches predetermined positions round such a figure. For telegraph purposes it is proposed to hold the plates at extreme positions of their movement by electromagnets 11 and 12. The arrival of a start signal on line L1 is used to release magnet 11 and let plate 3 commence an oscillation. When this plate reaches its neutral position a light beam from source 17 passes through the intersection to photo-cell 16 to produce an electric pulse used to release magnet 12. Later in the cycle as plate 3 is returning to its initial position light from source 21 falls on cell 19 through the intersection to reenergize magnet 11 to stop the plate in its starting position. Source 22 and cell 20 similarly re-energize magnet 12 to stop plate 7. As shown in Fig. 3, further photo-electric devices 28, 29, 30, 31 and 32 are positioned relative to the path of the intersection such that they produce pulses at delay times after the start pulse corresponding to the mid-points of the five code elements. These pulses are applied respectively to gates G23, G24, G25, G26 and G27 with the incoming signal. Coincidence of pulse signals at any gate results in a switching pulse being applied to the appropriate one of bi-stable devices 38, 39, 40, 41 and 42. The stored signals on these devices may be read out simultaneously or in any desired order by applying switching pulses to gates G43, G44, G45, G46 and G47. The bi-stable devices are then reset ready for the next signal.

Filed: 1975-10-30
Abstract: 1529856 Pivots INTERNATIONAL STANDARD ELECTRIC CORP 30 Oct 1975 [30 Oct 1974] 45025/75 Heading E2F A lever 16 (e.g. for operating a tumbler switch) is mounted in a hollow cylinder for pivotal movement about an axis perpendicular to the longitudinal axis of the cylinder by means of a substantially spherical bearing surface which cooperates with a bearing surface of the cylinder; a shoulder and recess arrangement being formed on the bearing surfaces in a plane parallel to the plane in which the lever is to pivot. As shown a bearing ball 12 has flattened ends 14 which engage flattened portions of the cylinder. Alternatively the ball shape can be formed from a number of cylindrical sections arranged along the pivot axis (Fig. 4 not shown). In either case the surface with the shoulder, flattened portion or recess can be of harder than the other surface so that the other surface can deform to it on assembly. In another embodiment a projection can extend from the cylinder to engage grooves either already in the ball surface (Fig. 6 not shown) or formed by engagement with the projection immediately after assembly.

[Also in Division C7] A sodium-zinc alloy, containing 0.5 to 4% sodium and having a particle size of 1 to 50 microns is mixed with a liquid hydrocarbon in the form of a paste, suspension or stable gel. The gel may be formed by shaking the mixture of hydrocarbon and alloy with 1 to 8% by weight, based on the hydrocarbon, of a surfaceactive agent such as a stearate of aluminium, zinc or sodium. Suitable liquid hydrocarbons have boiling points of 160-250 C., 6-16 carbon atoms per molecule, are exemplified by kerosene, naphtha, ligroin, mineral spirits, tetralin, decalin, high flash-point gasoline and mixtures thereof, and are generally used in volume ratios of 0À5 : 1 to 8 : 1 based on the zinc. The alloy may be prepared by melting together appropriate amounts of sodium and zinc and casting into ingots and can be comminuted in a steel ball mill containing the liquid hydrocarbon. Zinc hydrosulphite solutions may be prepared by reacting sulphur dioxide in aqueous solution with the above sodium-zinc alloy/liquid hydrocarbon compositions at 5 to 60 C. and at a pH of 3 to 8. The reaction may be carried out in static beds, agitated beds or rotating drums. The zinc hydrosulphite may be converted to sodium hydrosulphite by reaction with sodium hydroxide or carbonate at 0 to 65 C. In an exemplified process, the sodium-zinc alloy/hydrocarbon composition is circulated in water, together with liquid sulphur dioxide, through a tubular cooler at 35 C. After filtration the zinc hydrosulphite solution is converted to sodium hydrosulphite with 25% caustic soda. Na 2 S 2 O 4 .2H 2 O is salted out with sodium chloride and alcohol, filtered, washed with alcohol and dried under vacuum at 60-80 C.
