Title: Condenser winding machine
IPC: H01G13/02
Filed: 1944-11-06
Abstract: 594,409. Condenser winding - machines. DEHN, F. B. (Fast & Co., J. E.). Nov. 6, 1944, No. 21753. [Class 100 (i)] [Also in Groups VIII, XVII and XL] A machine for winding strip material into compact rolls to form condensers includes means for holding a binding strip for the roll, guide means for the binding strip, feeding means adapted to thrust the forward end of the binding strip into the bite of the strip material being wound, a binding strip cutter, means for sealing the binding strip on the condenser and power means for automatically operating the feeding and cutting means in timed relation. As shown the condenser is wound on a divided mandrel 62 from four strips of insulating paper from rolls P, P<1>, P<2>, P<3> and two strips of foil from rolls F, the rolls being so positioned that the foil strips protrude, one at each side, from the paper strips when wound into the condenser, Fig. 8. A binding strip B, Fig. 3, is fed through a guide 70 and a slot 72 between two blocks 73, 74 into the bite of two layers of the condenser when it is nearly wound. The strip is fed forward intermittently by a bevelled roller 83 pressing against an extension 84 of the block 73 and is severed by a cutter 75 made from strip material, having a bent portion 82 which is engaged and depressed by a boss 81 on a knife 67 as it advances to sever the paper strips, the foil strips having already been severed (see Group VIII). A' swab applies a spot of glue to the underside of the end of the binding strip so that the.outermost turn of the strip will be sealed. The feed roller 83 is mounted on a shaft 85, Fig. 4, carrying loosely a drum 90 fixed to a disc 89 bearing a dog 88 which engages a ratchet 87 on a drum 86 fixed to the shaft 85. A plate 92 movable in the direction of the axis of the shaft 85 is spring-urged against a friction disc 91 bearing against the drum 86. One end of a cable 97 is attached to a pivoted lever which is under the action of a cam on a shaft 105, and the other end is wound round and attached to the drum 90 so that as the cam moves the lever downwards, the drum 90 is rotated and 'thereby, through the dog'and ratchet mechanism, the drum 86, the shaft 85 and the feed roller 83 are rotated. When the lever is allowed to rise, the drum 90 is rotated in the opposite direction by a restoring cable 98 under the action of a spring 99, but the dog and ratchet mechanism does not allow the drum 86 to rotate. The blocks 73, 74, are held in a yoke 108 on a shaft 109, and are adjustable about this shaft as axis, an adjusting screw mounted in a member on the shaft 109 being spring-held in contact with a block. The operation of the various parts of the machine is synchronised by means of suitable cams on the shaft 105. Specification 594,452 is referred to.

Abstract: 723,539. Rendering photographic electrostatic images visible. FERRANTI, Ltd. Sept. 15, 1952 [Sept. 22, 1951], No. 22220/51. Class 98 (2). [Also in Group XVI] An electrostatic image formed by photographic exposure of a uniformly charged surface on a layer of photo-conductive insulating material on a conductive plate is rendered visible by forming a cloud of finely-divided powder particles and causing said particles to pass through a metallic grid connected to a fixed potential source into contact with the photo-conductive layer while this is connected to a fixed potential source at a different potential from that first-mentioned. As shown, an exposed electrophotographic plate 14 having a conductive support and housed in an earthed dark slide 13 is placed charged face down on an insulating gasket 12 over an aperture 15 in a light-tight insulating housing 7 and is developed by a white, e.g. cosmetic, powder 1 forced out through an apical aperture 3 of a cone 2 to form a neutral cloud of particles of opposite signs in the space 16 by vertical vibratory movement of the base of the cone by means of a motor 6, charged particles of an appropriate sign being selected by a control grid 9 in a metal plate 10 at a chosen fixed potential of the same sign as the charge on the exposed plate so that the particles reaching the plate are of this sign and a direct positive is obtained. By varying the grid potential the contrast may be varied, while a negative picture may be obtained by giving the developing powder a charge opposite to that on the exposed plate. Specification 723,534 is referred to.

Title: A process of manufacturing crystalline substances
IPC: B01D9/02
Filed: 1935-08-08
Abstract: Crystals are obtained by adding a concentrated aqueous solution of the substance to be crystallized at a temperature above its supersaturation point to a solution of another substance promoting its crystallization, the mixture being cooled to and maintained at a temperature at which the solution to be crystallized would by itself be supersaturated.  In an example a solution of sodium silicate containing 21,8 per cent Na2O and 21,1 per cent SiO2 at 60 DEG  C., is added to a cold 20 per cent caustic soda solution and the mixture cooled to and maintained at a temperature of 22 DEG  C. to give crystals corresponding to Na2SiO3 9H2O.  The caustic solution may be replaced by a solution consisting of 5 per cent caustic soda and 15 per cent common salt.  Sodium carbonate in the form of needles of Na2CO3, 7H2O is obtained by the addition of a warm solution containing 15,5 per cent NaOH and 13,4 per cent anhydrous Na2CO3 to a 22 per cent caustic soda solution, the mixture being maintained at 20 DEG  C. Sodium nitrate solution is used in promoting the crystallization of borax.  Specifications 427,496 and 427,497 are referred to.

Abstract: 582,701. Gas-actuated switches. REYROLLE & CO., Ltd., A., ALLAN, A., and SHANNON, R. Nov. 14, 1944, No. 22462. [Class 38 (v)] [Also in Groups XXVIII and XXIX] In a switchgear unit A including a gas reservoir B for operating the switch-gear, the gas supply line to the reservoir is protected against leakage arising within the unit by a lock-nut valve F which closes at reduced pressure and remains closed, even though the original pressure is restored, until deliberately reopened. The valve G', Fig.2, is biassed by a spring G<8> to close the gas supply passage F<1>, but is normally retained open in its seating H<2> communicating with the atmosphere at G'. When the pressure falls below a predetermined value, the spring G' overcomes the gas pressure and the valve snaps. on to its seating H', the section area a<2> being less than a. The section area a' is also less than a, so that return of the normal pressure to the passage F' does not reopen the valve. The valve carries contacts M which complete an indicator circuit N when the valve closes. Where a number of unit reservoirs are supplied from a main reservoir C through a buspipe D and branch-pipes D', a lock-nut valve F may be arranged in each branch-pipe and/or net to the reservoir C at P, an isolating valve D' and a non-return valve B' being included in each branch-pipe The gas used may be air, hydrogen, argon, nitrogen, or dichlorodifluoromethane.
