Title: Improvements in and relating to weighing scales
IPC: G01G23/34
Filed: 1922-12-14
Abstract: 214,292. White, A. E., (Computing Tabulating Recording Co.). Dec. 14, 1922. Indicating-mechanism; loose-weight apparatus. -An automatic weighing scale is provided with a reflector controlled bv the movement of the load support, whereby an image of at least a portion of a stationary chart is projected upon a screen. As shown in Figs. 3 and 4, the invention is applied to a scale of the pendulum weight type. The load is communicated through the rod 3, lever 5, and draw-rod 17 to a beam 18 provided with a pendulum bob 29 and adjustable poises 27, 28. Should the load exceed the normal capacity of the scale, one or more weights 61, Figs. 3 and 20, are lowered on to a holder 26 suspended from the end of the beam 18. The weights are normally carried by brackets 63 projecting from a vertically slidable bar 62, which may be held in any one of two or more positions by a spring catch 67. A mirror 35, Figs. 3 and 4, pivotally mounted at the centre of a fixed arcuate chart 39, reflects an image of a portion of the chart along the axis of an enlarging series of lenses 40, which image, after being reflected by mirrors 41, 42, is projected on to a ground-glass screen 43. The chart 39 is illuminated by a lamp 75, the light from which passes through a condensing lens 76 and is reflected on to the chart by a mirror 77 which pivots with the mirror 35. The mirrors 35, 77 are rocked by a wire 51 passing round a cam 50 and secured at its upper end to an arm 52 extending from the drum-rod 17. The wire 51 is kept taut by a pendulum 56 attached to the cam 50. A second chart 59 adapted to change the initial numeral of each weight indication on the chart 39 is operated by the cam-shaped end 74 of the bar 62 as the capacity of the scale is changed. When more than one weight 61 is provided, Fig. 20, the chart 59 is situated behind the chart 39 and is marked with a number of columns of indications, the appropriate column being viewed through a slot in the chart 39. When the load exceeds the normal capacity of the scale, the end of the beam 18 comes into contact with a spring plunger 402 and an indication of the number of weights 61 required to balance the load is shown on the screen 43. Computing-apparatus. - A computing chart 202, Figs. 15 and 16, marked with a number of columns of indications, each corresponding to a certain price per unit may be slidably mounted behind a plate 200 carrying the chart 39. A rack 205 attached to the chart 202 is engaged by a pinion 206 on a rod 208, the upper end of which is provided with a pointer 210 adapted to indicate on a price per unit scale. An operating knob 209 is provided by means of which the desired column on the chart mav be caused to register with a slot 203 in the plate 200 adjacent the chart 39.

Dec. 10, 1935, No. 34223. Convention date, June 6. [Classes 40 (iii) and 40 (v)] In the reception of telephone or telegraph signals sent by the carrier suppression system the local carrier current, which has to be applied to the demodulator jointly with the received side-bands, is derived from the received sidebands by combining them with the demodulated signal. As shown, the received sidebands are applied to a demodulator 3 which supplies the line 8 for the demodulated signals through a low-pass filter 7. The received side-bands are also applied to an auxiliary modulator 10 which is also fed by the signal from the output line 8, and the resultant is passed through an amplifier 14 selective to the carrier frequency and is used in place of the usual local oscillator for feeding the demodulator 3. The carrier may be of high or low frequency ; and telegraph signals may be sent by reversing the phase. The modulators or demodulators are preferably of the symmetrical type comprising four rectifiers in bridge formation.

Abstract: 615,907. Vibratory mechanism. WALTER, G. Dec. 21, 1945, No. 34803. Convention date, Dec. 21, 1944. [Class 80 (iv)] In a vibratory mechanism in which one element is rotated and rolled on another element, the surface of one of the elements being circular and the surface of the other non- circular, the non-circular surface comprises a zone with a radius of curvature equal or almost equal to the radius of said. circular surface which is bounded by zones of a different radii in such a manner that the tangents of the curves at the connecting points coincide. As shown in Fig. la, the element 1 has a circular internal surface which rolls on a fixed element 2. The surface of the latter is composed of zone AB of equal curvature to the circular surface of element 1, zones BC and DA of a smaller radius of curvature, and a connecting zone CD of an intermediate radius. This arrangement is stated to provide, as the member 1 rolls from point A to point B, a force of considerable value for effecting the vibratory movement. In Fig. 3, the stator 74 of an electric synchronous motor is mounted in a frame 73 by bearings 79 and prevented from rotating by a link 83. The rotor 76 is provided at each end with cavities 86 which roll on pivots 87 secured to the frame 73. The coacting surfaces of the cavities 86 and pivots 87 are formed as previously described so that a vibratory effect is produced on the frame 73 on rotation of the rotor 76. The Specification as open to inspection under Sect. 91 describes a circular element driven from a flexible shaft through gearing and a universal joint to roll around a non-circular surface of a recessed element which is thus vibrated. This subject-matter does not appear in the Specification as accepted.

Abstract: 1475138 Reducing heave ENERGY SYSTEMS CORP 8 Aug 1974 [10 Aug 1973] 34986/74 Heading E1H A buoyant body, e.g. a sphere for carrying drilling equipment, has a central well which reduces the rate of change in buoyancy with draft, so reducing the amplitude and frequency of heaving motion. The well 70 may be cylindrical as in Fig. 2, with the drilling equipment mounted on a float 82 in the well. Alternatively the well may be flared as at 90, Fig. 3, to give a reduced rate of change of buoyancy at the normal drilling waterline levels between B and C. Variations in the water level within the well may be reduced by restricting the entrance to the well, either by fixed constriction 74, Fig. 1, or by variable flaps and shutters (Figs. 5-9, not shown). In addition, a tube of adjustable length may depend below the well so that the well communicates only with water at a depth greater than the draft of the vessel. The tube also acts to damp the flow of water into and out of the well, and damps roll oscillation of the vessel. The roll frequency may be adjusted by means of an elevated ballast tank 52. The vessel has a number of propulsion units 42, and has anchor tunnels 44 arranged so that the anchoring forces pass through the centre 14 of the sphere.
