Title: Apparatus and method for rounding the edge of an opthalmic  lens
IPC: G02C7/02
Filed: 1973-08-02
Abstract: 1445197 Edging contact lenses BAUSCH & LOMB Inc 2 Aug 1973 [10 Aug 1972 (2)] 36835/73 Headings B3D and B3X A method of contouring the edge 45 of a contact lens 47 while firmly supported in a lens mould 49 and constituting with the mould a lens and mould assembly, the edge 45 being adjacent a face of the mould, the contouring being effected by apparatus 11 having a rotating material removing surface 44, comprises placing the assembly in a position spaced from the surface 44, inducing relative movement along a prescribed path between the surface and assembly to effect engagement of the lens with the surface, automatically centering the lens on the surface to substantially simultaneously engage all portions of the edge with the surface, maintaining the engagement with a constant force for a preselected period to remove a portion of the edge, and automatically disengaging the edge from the surface. In apparatus for carrying out the method, the lens and mould assembly is placed on a support 29 mounted for universal movement and rotation by means of a ball 31 on the end of an arm pivoted to a pair of bearing blocks 23 on a base 13. A slot 26 intermediate the length of the arm receives a roller 27 which is supported by a pin 28 and is urged by a spring 25 into engagement with a cam 19 on the drive shaft 18 of a motor 17 carried by a support 15. A second support 35 carries a motor 37 the drive shaft 39 of which has a plastics material collar 41 holding a metal sphere 53 which has a finely textured surface 44 of approximately 30 RMS constituting the material removing surface. Rotation of the cam 19 moves the arm 21 from a position spaced from the surface 44 to permit a lens and mould assembly to be placed on the support 29 to a position in which the edge 45 of the lens engages the surface 44 with a force determined by the spring 25 and for a time determined by the shape of the cam so that the surface 44 contours the edge of the lens 47, the cam thus moving the lens away from the surface. The ball 31 permits the support 29 to pivot as the lens engages the surface so that substantially simultaneous engagement of all the edge of the lens occurs with the surface 44 and the rotation of the surface imparts rotation to the lens. In another embodiment, the surface is constituted by a layer 139 of tight woven silk cloth over a layer 138 of cotton cloth on a metal sphere 137. Glycerin may be applied during contouring, a splash guard 143 being provided.

Abstract: 619,657. Endless-belt conveyers. GIBBS, S. T., WILSON, G. D., and BAKER PERKINS, Ltd. Dec. 19, 1946, No. 37384. [Class 78 (i)] In a biscuit conveyer, biscuits are conveyed along a path having a vertical component between a pair of endless conveyer bands, the biscuit conveying laps of which are caused to follow an arcuate path, the chord of which is vertical or has a predominant vertical component, by travelling against stationary convex backing or deflector plate means, the conveyer bands being made of soft, resilient or cushioning material. Biscuits from conveyer 1, Fig. 1a, are conveyed between resilient tensioned bands 28, 15, Figs. 1 and 1a, around the stationary curved guide 13 and are discharged on to a conveyer 31 over a knife edge 16 formed in the inner and driven band 15. To prevent biscuits from sticking to the outer band 28 a row of knobs 51, attached to springs 50, are caused to tap the band 28 by pivotal movement of a member 47a operatively connected to rods 45 which are moved longitudinally in bearings 46 by the engagement of their lower ends with driven ratchet wheels 44. Rollers 7, 10 and belts 28, 15 are constructed with resilient surfaces to prevent damage to biscuits, and the guide 13 may have a resilient surface covered with American cloth to allow the belts to slide freely thereon. In an embodiment (not shown), the continuous guide 13 may be replaced by a series of short guides, each having a reversed curvature relative to the former guide, with or without spaces therebetween over which the bands travel vertically and tangentially to the curved guides. The arrangement is such that the biscuits may be delivered from this sinuous path with either side uppermost depending upon whether an odd or even number of guides are provided. In a further embodiment (not shown) the plate 13 is provided with a series of closely spaced sunk rollers throughout its length. Specifications 536,262, 548,429, and 570,873 are referred to.

Abstract: 1,031,148. Reverse parallel valves for controlling A.C. power. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 14, 1964 [Sept. 17, 19631, No. 37442/64. Heading H2H. A pair of reverse parallel connected valves 1, 2 are controlled by a thyristor 5 connected to the centre taps of autotransformers 7, 8 as shown. Before either valve fires most of the supply voltage 4 appears across the autotransformer 7 and when the thyristor 5 is fired by a phaseshifted pulse 11 or by closure of a switch shunting these conductors half of transformer 7 is connected in parallel with half of transformer 8 through rectifier 12 or 13, thus placing the whole of the voltage of transformer 8 across the cathodes and ignition electrodes of the valves, firing whichever valve has positive voltages at both the ignition electrode and anode. Firing of either valve reduces the voltage across the transformer 7 below that of a Zener diode 6 which cuts off the thyristor 5 to prevent afterburning. The transformer 8 may be arranged to step up the voltage from transformer 7 by suitable taps. The arrangement enables a thyristor of reduced voltage rating to be used. The load 3 may be a welding transformer.

Abstract: 1521451 Focusing of cine cameras AGFA GEVAERT AG 13 Sept 1976 [11 Sept 1975 17 March 1976 (2) 14 May 1976] 37784/76 Heading G2A A cine camera having a lens of variable focal length has a manually operable control movable from one position to another, wherein the said movement sets the lens to a predetermined focal length, irrespective of the focal length setting prior to such movement. As shown, the camera has a zoom lens comprising optical elements 1b, which is adjusted by a rotatable collar 3 on the lens barrel 1a. A further collar 2, having a handle 2B, also mounted on lens barrel 1a, adjusts the focus. Collar 3 has a fixed pin 3a, and is shown in three different positions, 3a, 3a', 3a", as the collar rotates. Similarly collar 2 has a fixed pin 2a, shown in three different positions, 2a, 2a', 2a". Positions 2a, 3a may correspond to the positions of collars 2, 3 for focus at infinity and for maximum focal length, and positions 2a', 3a' for minimum distance and minimum focal length. Positions 2a", 3a" represent the positions of the collars for intermediate positions. The intermediate positions 2a", 3a" may be predetermined so that they represent positions of collars 2, 3 for acceptable photographs under particular pre-selected conditions, e.g. indoors or outdoors, daylight or artificial light. These positions may be rapidly set by a person having little experience in manipulating cine cameras. Two jaws 7, 13 are shown in full line in their rest positions, pivoting on respective fixed shafts 8, 11. An extension of jaw 7 has a slot 7a engaging a pin 5b on a vertical slider 5 biased into the rest position shown by a spring 6. Thus depression of slider 5 in direction 9 causes jaw 7 to pivot clockwise. A gear 10 on jaw 7 meshes with a gear 12 on jaw 13, so that clockwise movement of jaw 7 causes jaw 13 to pivot anti-clockwise, the two jaws closing together into the position shown in broken lines (7", 13"). Jaw 7 has a lug 7b which can entrain pins 2a and 3a, and jaw 13 has a lug 13a which can similarly entrain these pins. Thus whatever the positions of the pins may be (e.g. 2a, 3a or 2a', 3a'), they are entrained by one or other of the two lugs as the jaws close, and are brought to the predetermined positions 2a", 3a". Thus these predetermined settings of collars 2, 3 can readily be obtained by an inexperienced operator merely by pressing slider 5, irrespective of what their previous settings may have been. On releasing slider 5, it is drawn upwards again by spring 6, and the jaws 7, 13 return to their original positions, but the collars 2, 3 remain as set. The collars may have handles, as at 2B, so that they may be operated in the normal way at the discretion of the operator. Other forms of mechanism for rapidly obtaining this predetermined focus setting by an unskilled operator are described. In the embodiment of Figs. (not shown), 6 and 7, two alternative rapid settings are provided.

A camera shutter comprises an opening blade 4 and a closing blade 5 which on release from the cocked position respectively open and close an aperture 21 in plates 1 and 2 at a time interval determined by an escapement mechanism 25, 26, 27; the blades are operated by spring-loaded levers 9 and 11 which are held in the cocked position by spring-loaded pawls 22 and 13 which are released by lever 38 via time-control disc 36; pawls 13 and 22 are arranged in offset arrangement so that opening lever 9 is released before closing lever 11 and the run-down of the latter is retarded by an escapement lever 23 to an extent depending on the setting of the escapement mechanism 25-27, which is set by different positioning of a control pin 28 of a toothed segment 24 by a control cam 29 of a time-setting element 30. After running off, the shutter is cocked by rotating lever 9 through a distance s from the position shown as chain dotted, thus moving lever 11 similarly by means of a tab 15, until a lug 12 of the former is engaged by pawl 22. In this position the opening disc 4 covers the closing disc 5 by a sector α; on release, lever 9 runs down by an amount a, so that disc 4 runs down by an amount α 2  leaving an overlap of α 1 ; thus the opening disc 4 has a greater starting travel up to the commencement of exposure compared with the termination of exposure by closing disc 5, so that the opening of the aperture is effected faster than the closing thereof.
