Title: Manufacture of lenses from transparent polymerizable organic plastics
IPC: B29D11/00
Filed: 1946-12-05
Abstract: Polymerizable thermoplastic or thermosetting material is polymerized to the stage at which it is strong enough to be cut, but is deformable under light pressures and at moderate temperatures, then lens blanks having dimensions closely approximating to those of the finished lenses are produced from the material, and finally the blanks are moulded between optically accurate dies under a small pressure at a temperature that will complete the polymerization.  The material may be methyl methacrylate monomer or allyl methacrylate monomer or a mixture of both.  Such a mixture (20 parts by weight of methyl methacrylate and 80 parts of allyl methacrylate) is polymerized between two smooth flat parallel plates of glass or metal at 60 DEG  C. for 8 hours, and from the sheet thus produced a lens blank is cut and machined and polished to approximate lens dimensions.  This blank is then moulded in a hand-operated press at 140 DEG  C. for 2 hours at a pressure of the order of 50 pounds per square inch.  In another example, a lens blank of partly polymerized methyl methacrylate is coated with liquid or viscous partly-polymerized allyl methacrylate, as described in Specification 585,580 or Specification 610,962 before moulding at 140 DEG  C. and 100 pounds per square inch for 30 minutes.  Specifications 416,398, [Group XX], and 572,748, [Group V], also are referred to.ALSO:Polymerizable thermoplastic or thermosetting material is polymerized to the stage at which it is strong enough to be cut but is deformable under light pressures and at moderate temperatures, then lens blanks having dimensions closely approximating to those of the finished lenses are produced from the material, and finally the blanks are moulded between optically accurate dies under a small pressure at a temperature that will complete the polymerization.

Abstract: 369,591. Photographic shutters. GAUTHIER, A., Calmbach-on-Enz, Germany. Dec. 12, 1930, No. 37496. Convention date, Dec. 12, 1929. [Class 98 (i).] A shutter has a locking device for the driving mechanism releasable from a distance by a pull member. As shown, a pull on the cord l rotates the lever i, and when the pin g<1> leaves the circular portion h<1> of the cam h the lever b is returned by the spring e to its run-down position thereby imparting rotary motion to the shutter blades. The lever end b<3> then opens the shutter, which closes again under spring action. On releasing the pull the lever i is returned by a spring into its original position. The lever i may be held in the pulled-down position by a yielding detent. In a modification the shutter-blade lever is held from motion when the lever b is stressed by a pin inserted into a hole in the shutter casing and removable by a pull on the cord l.

Abstract: 841,089. Gas-liquid contact tower. HAMON, M. Dec. 3, 1957, No. 37603/57. Class 55 (2). [Also in Group XIII] In a tower 1 for cooling liquid such as water, some of the cooling-air entering a peripheral opening 11 passes below packing 33 to openings 15 to enter a central casing 16 containing packing 32 and a fan 3 which, except in cold weather, when it is stopped, directs that air into the tower. The remainder of the cooling- air passes up around the casing 16, the top of which may be divergently conical. The water to be cooled passes from a duct 13 through passages 4, 5 to distributing pipes 6 of the natural-draught section around the casing 16 and through channels 7 to distributing pipes 6 of the fan section within the casing. Valves in the passages apportion the water flow to the cooling sections, and either may remain unsupplied with water. The speed of the fan 3 is variable so that the proportion of the airflows through the two sections may be varied. There may be several fan-and-casing units in one tower. Specification 224,557, German Specification 531,366 and French Specification 720,676 are referred to.

Abstract: 931,764. Cutting-apparatus. BAXENDEN CHEMICAL CO. Ltd. Nov. 16, 1959 [Nov. 17, 1958], No. 37837/62. Divided out of 931,763. Class 31(1). [Also in Groups XXII and XXIII] A square or other non-circular section 21 of foamed plastic is formed into a round rod by a rotating tubular cutter 11 against which the sections are fed axially through a guide tube 13 by hand or mechanically so that the formed rod passes through the cutter; the cutting edge of the cutter may be a plain circular knife-edge or be constituted by one to eight inclined surfaces each of which is at an angle of up to 30 degrees to the plane normal to the axis of the cutter. The bore of the cutter is of the same diameter as the rod for a short distance behind the cutting edge and then opens out to a clearance diameter. The cutter body is relatively thick to assist in heat dissipation and cooling may be supplemented by a cold air blast. The cutter is driven by a hollow shaft 17 and extends a short distance into the guide tube 13, which is of square section to prevent the section 21 from rotating and has a tapered entrance section 14. Waste material falls away outside the cutter and rotation of the round rod after passing through the cutter is prevented by friction with a tube support 12 or a trough or a set of two or more grooved rollers. The rods are subsequently sawn into discs as described in Specification 931,703.

Class 40 (6). Fig. 1 shows a bi-stable state circuit in which discharge tubes B1a, B1b are reciprocally and directly coupled between anodes and control-grids and have a common cathode resistor R15. The circuit is switched by a control voltage applied at terminal 7 to the grid of tube B1a and the anode of each tube is connected via a resistive network so that the voltage on a common conductor connected to a terminal 6 remains substantially constant. The anodes of the tubes are also connected via resistive networks to terminals 4 and 9 so that a square-wave voltage related to that generated at the respective anode when the circuit is switched is produced at these points, Fig. 2 (not shown). The stability of the circuit may be improved by means of a feedback circuit connected between an output point such as terminal 5 and input terminal 7. The terminal 7 may be connected to the corresponding terminal in other similar switching circuits F<SP>1</SP>, F<SP>2</SP>, F3. Neon tubes L1, L2 indicate the state of conductivity of tubes B1a, B1b. Fig. 3 shows a coincidence circuit comprising switching circuits F, F<SP>1</SP>, F2, the voltage at the output terminals R, S occurs which differs from the normal voltage only when a negative voltage is applied at terminal P and a positive voltage at terminal Q.
