IPC: B66B1/12
Filed: 1955-08-03
Abstract: 792,452. Linkwork. GENERAL ELECTRIC CO., Ltd. Aug. 3, 1956 [Aug. 3, 1955], 22301/55. Class 80 (3). [Also in Group XXXVII] A hand-lever 1 is adapted to move a roller contact 2 over a potentiometer 3 by means of which a reference voltage is selected for determining the speed of a winder motor. The lever moves in a slot 4 and, in the " off " position, is at the centre of cross-path 7. The direction of motor-operation is selected by movement of the lever from the central position into either the path 5 or path 6. The motor speed is increased when the lever is moved along either of the parallel paths 5, 6 away from the cross-path 7, whilst lever-movement in the opposite directions decreases the speed of the motor. A pair of projections 10, 11, on the hand-lever are adapted for selective engagement with recesses in gear segments 13 or 15 which have a common gear-wheel 16, so that rotation of the lever about the pivot 9 enables shaft 17 to drive an arm 18 which carries the roller contact 2. The potentiometer segments 8 are arranged on the periphery of a drum.

Abstract: 628,971. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 26, 1946, No. 22380. Convention date, July 26, 1945. [Class 40 (iii)] A television circuit arrangement for controlling the deflection of the scanning beam of a cathode-ray tube comprises means actuated by the output of an oscillator operating at frame frequency for temporarily arresting the operation of the oscillator controlling the line deflection so that the latter oscillator re-starts at the proper time to produce interlaced scanning. In the described embodiment the rectangular wave output (at point 87) of a picture frequency (30 per second) multi-vibrator 60 synchronized by field frequency (60 per second) pulses developed by differentiation of field saw-tooth waves from field frequency generator 41 in the network 55, 56, is itself differentiated by means of the network 88, 89 to produce the wave-form a<1>c (junction point 90) which is additively combined with the synchronizing field frequency pulses (junction point 57) to provide a positive keying voltage pulse train (junction point 59) the amplitude of which may be varied and the position of alternate pulses of which on a time scale by suitable adjustment of resistor 93, may be shifted (on a time scale) by an amount equal to a one-half line scanning period. The keying pulses thus produced are applied to the grid of valve 30, the cathode resistor 18 of which is common to the valves 12, 13 of the cathode-coupled line frequency multi-vibrator 11 so that the operation of the latter is interrupted each time a positive pulse of sufficient amplitude appears on the grid of valve 30.

Title: Improvements in or relating to calcium chloride
IPC: C01F11/32
Filed: 1955-08-05
Abstract: Aqueous calcium chloride solution obtained by the ammonia-soda process is heated for more than one hour until dark colloidal impurities are substantially completely precipitated, and said impurities are separated therefrom.  It is desirable to concentrate the solution prior to heating to 30 per cent CaCl2 by weight and remove precipitated salts such as sodium chloride prior to said heating, to continue heating for at least 12 hours, and to employ a temperature of at least 50 DEG  C. Temperatures below boiling, or reflux conditions, are preferred, to avoid excessive concentration. In one of the examples the liquor after removal of suspended matter in settling tanks was concentrated to 40 per cent by evaporation at 90 DEG  C., sodium chloride removed by settling, the remaining liquor evaporated to 55 per cent calcium chloride at 130 DEG  C. in 2 hours, and the resulting liquor maintained at 127 DEG  C. hours, and the resulting liquor maintained at 127 DEG  C. for 7 days.  The product was then filtered using a filter aid.  In a second example temperatures were maintained at 68-137 DEG  C. for 1-44 hours.

Abstract: 795,001. Optical systems. PANAVISION, Inc. Aug. 5, 1955 [Aug. 11, 1954], No. 22598/55. Class 97(1) A system particularly for motion picture photography or projection comprises, in optical alignment, an objective, an anamorphoser and an astigmatic device correcting any astigmatism in the combination of objectives and anamorphoser such as is introduced when the focusing of the objective is varied. As shown the anamorphoser 2U comprises two glass prisms arranged before the objective 30 and arranged to give a compression of the image in the horizontal plane when the object is focused for infinity. The astigmatism produced by the system 20 when the objective is focused on near objects is corrected by an astigmatic device 10 comprising a plano-cylindrical convex lens 12 and a plano-cylindrical concave lens 14 rotatable in opposite directions about the optical axis to vary the astigmatic effect produced thereby. The rotation may be effected by a gear 19 driven from a control member 50 which simultaneously adjusts the focus of the objective 30 by a gear 32 to set the astigmatic correction automatically to the object in focus. The lenses 12 and 14 may be of equal or unequal power or may be both positive or both negative.

Abstract: 1294287 Workholders APPLIED POWER INDUSTRIES Inc 19 April 1971 [4 March 1970] 22639/71 Heading B3B A workholding device includes a base member a hollow collet 26 rigidly secured thereto in a cylindrical bore, an actuator 30 movably mounted on the base member, and hydraulic piston-and-cylinder arrangements for moving the actuator into engagement with the collet to cause the latter to grip a workpiece, two fluidflow ducts being provided and opening in the collet-accommodating bore and arranged to allow flow of fluid into the hollow collet and to allow flow of fluid around the exterior of the collet.  The hydraulic piston-and-cylinder arrangement comprises one or a pair of pistons 32 whose rods 94 are connected to the actuator 30, and are biased by springs 104 into an actuator position corresponding to collet release. Actuator 30 embodies a tapered seating 85 which cooperates with a similarly tapered head portion 28 of the collet, the head portion 28 being longitudinally slotted. The stroke of pistons 32 and thus actuator 30 is adjusted by means of threaded rings 116 embodying resilient wiper rings 118. Ingress of foreign matter between the actuator and base member when the actuator is operated is prevented by a shield plate 122. The actuator includes a skirt 86 which surrounds collet 26 to guide movement of the actuator. The collet 26 is screwed into its base socket 34, and is adjustable relative thereto by re-positioning of a stop screw 82 in the plug 76 which closes the lower end of socket 34. As shown, a plurality of assemblies as so far described are mounted in juxtaposition upon base-plate 18. Each assembly embodies fluid passages which, when the assemblies are so juxtaposed, align with corresponding passages in the other assemblies to provide a common passage system. Fluid-tight seals are provided where the passages interconnect. Thus, each assembly has a tangential passage 40 for supply of coolant to the collet interior; a tangential passage 42 for supply of flushing fluid to the collet exterior; and passages 50, 52 for supply of hydraulic fluid to the actuator pistons.
