Title: Wire cutting mechanism
Inventor: BONDS ALBERT
IPC: B23D21/00
Filed: 1959-11-17
Abstract: 926,188. Shearing. PREFORMED LINE PRODUCTS CO. Nov. 17, 1959, No. 38935/59. Class 83 (4). A cutting mechanism comprises a rotatable member, a knife mounted thereon and movable to a cutting position where it projects beyond the periphery of the member, a stationary cooperating shearing edge, means for guiding the stock to be cut along a path parallel to the axis of rotation of the member and across the path of the knife, means for projecting the knife after a predetermined number of revolutions of the rotatable member and means for driving the said member. The rotary member comprises a flywheel 13, mounted on a hollow spindle 20 and driven by a motor 15. Journalled in the spindle 20 is a shaft 30, which is driven through a layshaft 24 to run in the same direction as, but at a lower speed than the hollow spindle 20. A cam 52 is adjustably secured to the shaft 30 by bolts which pass through arcuate slots 55. Mounted on the flywheel is a guide block 44 in which slides a carriage 42. The carriage supports a roller 50, which follows the cam 52 under the influence of a spring 58, and also supports a knife 40 with a cutting portion 41 which co-operates with a shear edge 61. The velocity ratio between the spindle 20 and the shaft 30 is determined by the sizes of the pulleys 27, 28, 34 and 35 and is arranged to cause the knife 40 to project after the flywheel has completed a predetermined number of revolutions. A wire to be cut is fed as a continuous length along a guide 60 and across the shear edge 61, to be cut by the knife 40 when the required amount is over-hanging the edge. The carriage 42 may be operated by a crank and connecting rod, and the velocity ratio between the spindle 20 and the shaft 30 by an epicyclic gear. A solenoid may be used to project the cutter, in association with a timing device.

Abstract: 1,194,007. Optical apparatus. TECHNOLOGY, MINISTER OF. Oct. 22, 1968 [Aug. 25, 1967], No.39182/67. Heading G2J. An apparatus for producing coherent light at an adjustable desired frequency includes means for projecting a laser beam 4 through a liquid 5 (e.g. carbon disulphide, deuterated benzene, carbon tetrachloride, bromoform) to transfer some of the energy into a quasi-continuous spectrum, a crystal 1 having non-linear dielectric properties disposed to receive the output from liquid 5 and mix or heterodyne at least one frequency from the quasicontinuous spectrum with the laser beam and control means 2 surrounding the crystal 1 to control the phase-matching of the mixing or heterodyning interaction to produce a coherent light beam 6 at the desired frequency. The crystal 1 is preferably lithium niobate which is disposed with its optic axis at right angles to the direction of propagation and to the plane of polarization of the laser beam, although a crystal of proustite may be used. The crystal is located in a temperature control enclosure 2, the temperature of which can be adjusted in the range - 150‹C. to + 540‹C. The laser is preferably a neodymium-in-glass type of wavelength 1À06 microns which gives a desired output in the range 0À5 to 0À8 microns. However, a ruby laser may be used which gives output wavelengths to the range 0À47 to 0À59 microns. When the laser beam of known wavelength enters the crystal together with the frequencies forming the quasi-continuous spectrum, the laser beam may be caused, by temperature control of the crystal, to interact with one of the frequencies of the spectrum, provided they are phase-matched, to either give a new sum or difference frequency.

Abstract: In preparing plastics surfaces (e.g. of celluloid, cellulose acetate, polyvinyl chloride, polystyrene or methyl methacrylate) for receiving a metallic layer (e.g. of Ag) such as is required for example in mirrors, a plastics surface is treated with a solution which simultaneously removes any grease, cleans and wets the surface without attacking it and also forms an initial layer on the surface after the solvent has evaporated, the solution being SnCl2 in a liquid which is a grease solvent, the surface being allowed to dry after treatment with the solution and before further treatment.  The solution may be of SnCl2 in pure alcohol.  Preferably the grease solvent is in an aqueous solution.  The surface having the initial layer thereon may be rinsed with H2O, rinsed in distilled H2O containing SnCl2, rubbed with a brush steeped in distilled H2O containing SnCl2, treated with a solution containing distilled H2O, alcohol and SnCl2, and be metallized by immersing one or more times in an ammoniacal solution containing AgNO3, KOH and glucose. Alternatively Ag can be applied electro-chemically. The coated surface can be dried and varnished.

Abstract: 926,559. Automatic control for helicopters. BENDIX CORPORATION. Nov. 16, 1961 [Nov. 18, 1960], No. 41100/61. Class 38 (4). In a system for controlling a rotary wing aircraft, means for automatically controlling roll, pitch and heading are trimmed by signals dependent on the setting of means for varying altitude or lift by controlling the collective pitch of the rotary wing. As shown, roll, pitch and azimuth altitude gyros 3, 3<SP>1</SP>, 311 control follow-up servomotors 5, 5<SP>1</SP>, 5<SP>11</SP> which, when clutches 11, 11<SP>1</SP>, 11<SP>11</SP> are engaged, respectively control main rotor lateral cyclic pitch, main rotor longitudinal cyclic pitch, and tail rotor pitch so as to maintain a helicopter in a desired altitude automatically. Manual controllers 8, 8<SP>1</SP>, 8<SP>11</SP> follow, and thereby indicate, the operation of the servomotors. When it is desired to adjust altitude a lever 12 is operated manually or automatically to vary the collective pitch of the main rotor. Electric signals from a generator 13 operated by lever 12 are applied to the roll, pitch and azimuth servo systems to provide the necessary trim correction for the changed conditions. The magnitude of the trim signals may be varied with airspeed by variable gain deivces 2, 21, 2<SP>11</SP>. When automatic, control is disengaged the trim signals are maintained at zero during manual control by means of a synchronizer 14.
