Title: Apparatus for dispensing pre-determined lengths of strip material
IPC: B65H20/22
Filed: 1968-04-25
Abstract: 1,204,054. Rolled strip dispenser. DYMO INDUSTRIES Inc. 25 April, 1968 [31 May, 1967], No. 19647/68. Heading A4G. [Also in Divisions B8] Apparatus dispensing stencil labels 18, Fig. 1, for manual removal or automatic adhering to invoices 22, the labels being cut to accurate length from a coil 14 from which label forming strip 12 is pulled off by an endless belt 44 of teeth 84, Fig. 2, engaging strip holes 38 when the belt drive shaft 94, Fig. 3, is connected in a solenoid latch one tooth clutch 170, 146, 144, Figs. 3, 6, to a continuously operating drive motor 110, Fig. 5, under the control of a timing mechanism and variable cam selector 160, Fig. 2. Operation of switch 113 continuously drives motor 110. Operation of switch 152 or pedal switch 154 momentarily energises solenoid 156, Fig. 6, to withdraw latch 130 from the single tooth 128 of clutch 126, Figs. 5, 6, to allow a cam shaft 124 and cam 160 thereon to make one rotation. This cam has a manually adjustable gap 174 into which follower 162 falls to actuate switch 166 energising solenoid 170 whereby clutch 142, Figs. 3, 6, engages to allow the motor to drive shaft 94 and belt 44 to dispense a label. When follower 162 leaves gap 174, latch 146 returns to release clutch 142 by engaging a tooth 144 determining the accurate length of a dispensed label. A cam 196 on shaft 124 then actuates a spring-loaded cutter 192, Fig. 5 or 36, Fig. 1 to sever strip 12. The severed stencil may be fed into a tray device 46 across which moves a strip of e.g. invoices 22. The multi-layer strip 12 forms stencils 18 having an upper rear adhesive strip 32, a carbon paper 30 and a front stencil sheet 28. Another cam 240 Figs, 5, 6 then presses a tray back 210, Fig. 3, on to the invoice strip and cam 242 presses a front pressure plate 220 on to the strip to hold it during cutting and presses via pad 232 the adhesive strip 32 on to the invoice. Different widths of strip may be accommodated by adjusting spring-loaded coil carrier 54 and guide 218, Fig. 3.

Abstract: 813,157. Radial-flow turbines and compressors. INTERNATIONAL STAL CO. A.B. June 26, 1957, No. 20159/57. Class 110 (3). In a blade-ring assembly for contra-rotating radial-flow steam or gas turbines or compressors, the blades of any one bladed ring are, when viewed as a developed plan, disposed at an oblique angle with respect to the blades of the adjacent blade ring or rings. Developed portions of two adjacent blade rings are shown in the Figure, the portions being shown side-byside for clarity and each comprising bladecarrying rings 2 and 3 with blades 1 extending therebetween. The blades at the left-hand side of the Figure are inclined at an angle α 1  to the axis of the machine, and the blades at the right-hand side of the Figure are inclined at an angle α 2  to the axis. The blades of the two blade rings are inclined to each other at an oblique angle α 3 . Instead of being inclined in opposite directions to each other as shown, the blades of the two blade rings may be inclined in the same direction but by different angles of inclination. The blades of one blade ring may be disposed in the normal way at right angles to the carrier rings while the blades of adjacent blade rings are inclined to the carrier rings.

Title: High resolution laser pattern defining apparatus
IPC: B23K26/20
Filed: 1968-04-29
Abstract: 1,236,224. Removing metal by lasers. R.C.A. CORPORATION. 29 April, 1968 [12 May, 1967], No. 20174/68. Heading B3V. [Also in Divisions G2 and H1] In a high resolution pattern defining apparatus the entire given area of the surface of a member to be defined is illuminated from a pulsed laser with coherent light which varies in relative intensity from point to point over its cross-section in accordance with the pattern. In a first embodiment Fig. 1 (not shown) a beam of coherent light from a pulsed laser is widened into a parallel beam by two convex lenses before passing through a transparency carrying the predetermined pattern to be engraved so as to effectively spatially modulate the laser beam. The beam is narrowed by means of two further convex lenses and then projected on to a solid member to be engraved. If the duration of the laser pulse is short enough i.e. less than 100 nanoseconds and of sufficiently high amplitude e.g. 2 joules where the member is copper, no significant amount of heat transfer takes place from point to point of the member and high resolution engraving can be achieved. The member being engraved may be a semiconductor. Instead of using a transparency the spatial modulation may be achieved using variable reflection or scattering of light. The apparatus may be used for engraving a hologram of a scene, Fig. 2. A quartz wedge beam splitter 208 splits the laser beam 202 into a reference beam 204, 212 and a second beam 206 which after being widened by lens 218 is spatially modulated by the pattern on transparency 220 and projected on to the member 214 as shown. The information beam 224 and reference beam 212 produce an interference pattern on member 214 forming a hologram, which interference pattern is engraved on member 214. By making member 214 of a magnetic material the pattern may be defined in magnetic form.

Title: Preparation of isocyanates containing phosphorus
Inventor: FIELDING HAROLD CROSBIE
IPC: C01C3/20
Filed: 1959-06-12
Abstract: Phosphorus triisocyanate P(NCO)3 is obtained by heating sodium cyanate or potassium cyanate with phosphorus trichloride in the presence of a polar organic solvent that is inert towards the reactants.  An inert non-polar organic solvent may also be present in addition to the polar solvent.  Specified polar solvents are nitriles, ketones, nitroparaffins and esters, e.g. aceto nitrile, acetone, methyl ethyl ketone, nitromethane, nitroethane and ethyl acetate, and specified non-polar solvents are benzene, toluene, xylene, kerosene, petroleum ether, diphenyl, and a diphenyl/diphenyl oxide mixture.  It is preferred to use a solvent mixture containing 10 to 20% by volume of the polar solvent. Several examples are given. On standing, or on cooling, the product forms a white thermolabile polymer which renegerates the monomer on heating.  Phosphorus triisocyanate and phosphoryl triisocyanate polymerize in the presence of triethylamine, sodium methoxide, aluminium chloride or dibutyl tin diacetate to form compounds which do not regenerate the monomers on heating.ALSO:Phosphorus isocyanates of the formula RnP(NCO)3-n in which n is 0 or 1 and R is an alkyl, alkoxy, aryl, aryloxy, or alkylaryl group which may be substituted react with polyfunctional compounds containing reactive hydrogen atoms, e.g. polyols, polyamines, polyesters, or polyethers to give polymeric compounds useful as textile auxiliaries for surface coating and in materials of construction such as glass fibrereinforced plastics.  Some of the isocyanates in which n is 1 also polymerize spontaneously.ALSO:Isocyanates of phosphorus having the general formula: RnP(NCO)3-n are obtained by heating sodium cyanate or potassium cyanate with a chloride of phosphorus having the general formula RnPCl3-n in the presence of a polar organic solvent that is inert towards the reactants, R being an alkyl, alkoxy, aryl, aryloxy or alkylaryl group which may be substitued and n being 0 (see Group III) or 1.  An inert non-polar organic solvent may be present in addition to the polar organic solvent.  Specified polar solvents are nitriles, ketones, nitroparaffins and esters, e.g. acetonitrile, acetone, methyl ethyl ketone, nitromethane, nitroethane and ethyl acetate and specified nonpolar solvents are benzene, toluene, xylene, kerosene, petroleum ether, diphenyl, and a diphenyl/diphenyl oxide mixture.  Examples are given for the production of (1) C6H5P(NCO)2 which polymerised on standing to give a viscous polymer and formed a bis-methylurethane with a methanol/ether mixture, and (2) C2H5P(NCO)2. The products react with compounds containing reactive hydrogen atoms, e.g. alcohols, amines, hydrazines, oximes, ureas, reactive methylene compounds, carboxylic acids, inorganic acids, inorganic hydroxides and inorganic amino compounds.  If the compounds containing reactive hydrogen atoms are polyfunctional they react to give polymeric compounds (see Group IV(a)).
