Title: Plasticised compositions
Inventor: DILKE MAX HENRY
IPC: C08K5/12
Filed: 1951-08-23
Abstract: Polymers having at least 70 per cent. of vinylidene chloride units in their molecular structure are plasticized with dimethyl phthalate or dimethyl tetrachlorophthalate.  The polymer may be polyvinylidene chloride or a copolymer of vinylidene chloride with one or more of vinyl chloride, methyl acrylate, ethyl acrylate, methyl methacrylate, dimethyl maleate and fumarate, diethyl maleate and fumarate, vinyl acetate and acrylonitrile, preferably a vinylidene chloride-vinyl chloride copolymer or a terpolymer prepared from a mixture of vinylidene chloride, vinyl chloride and dimethyl or diethyl maleate or fumarate.  The plasticizer may be added to the polymer by direct mixing, by adding the plasticizer dissolved in acetone or benzene to the powdered polymer and removing the solvent, by dissolving polymer and plasticizer in a common solvent which is removed by evaporation, by adding a solution of the plasticizer in a water-miscible solvent such as ethanol, acetone or dioxan to an aqueous dispersion of the polymer, or by adding the plasticizer to the monomer mixture prior to polymerization which is preferably effected in aqueous dispersion in the presence of a non-ionic dispersing agent.  A lightstabilizer such as 5-chloro-2-hydroxybenzophenone may be incorporated in the composition.  In an example, vinylidene chloride, vinyl chloride and dimethyl or diethyl maleate are copolymerized in aqueous dispersion in the presence of dimethyl phthalate using caprylyl peroxide as catalyst, gelatine or polyglyceryl stearate as dispersing agent and sodium pyrophosphate as buffer.  Specifications 640,120 and 711,355 are referred to.

Abstract: 710,768. Electric incandescent lamps. BOTTKE, H. Aug. 24, 1951 [Aug. 26, 1950], No. 20005/51. Class 39 (2) The bulb of an electric incandescent lamp is provided with, or formed of, two portions 21, 22 of different colour, e.g. one red, the other green, with separate filaments 24, 26 that can be switched on alternatively, e.g. for signalling purposes, the two parts of the bulb being separated by a transverse metal screen 31 provided with a flanged edge 34 to ensure demarcation of the colour when either filament is switched on. Rigid supporting wires 30b, 30c for one end of the respective filaments are connected by separate leading-in wires to end contacts 23, 25, the other end of each filament being connected to a common supporting-wire 30a that is connected to the shell of the end cap at 27. Support for the screen 31 is provided by offsetting the filament supporting wire 30b and welding it to the screen at 33, and also by an opaque insulating bead 32 between the supporting wire 30a and the screen, which is provided with holes for the passage of both wires. Instead of flanging the edge of the screen downwardly as shown, the edge may be T-shaped in section. Alternatively, the screen may be planar, and the outer area of the bulb adjacent to the edge of the screen provided with an opaque strip or layer of material, e.g. metal. Fig. 6 shows the lamp mounted within a reflector 36 and associated cover glass or lens 37, the plane of the internal screen 31 being below the upper edge of the reflector, and the latter being formed with two different radii of curvature such that, with the lower filament energized, the reflected rays mainly intersect one another above the plane through the edge of the reflector. With the upper filament energised the cover glass 37 is mainly illuminated directly.

Filed: 1921-07-26
Abstract: 187,719. Eaton, W. S. July 26, 1921. Milling - machines. - A machine of the kind in which a pattern is traced out by a stylus on the end of a pendulum arm adapted to cause relative universal movement on a single plane between a plate support and a tool carrier, is provided with a rotatable circular pattern plate having circumferentially arranged characters and with a layout disc projecting beyond the plate whereby a design compiled on the disc may be traced out by successive adjustments of the plate. As shown the invention is applied to the machine described in Specification 153,186, [Class 100 (ii), Printing processes &c.], wherein a pendulum 18 is universally connected at one point to a bracket 20 and at its upper end to a movable table 14 carrying a tool 16 acting on the work carried by a fixed support 10. A circular disc 25 bearing letters and numerals on both sides is rotatably mounted by means of a stud 24 on a base 22 removably supported on the pattern table 21. Between the table and the disc and rotatable on the same stud is a layout disc 27 projecting beyond the disc 25. In the reproduction the characters are inverted and the sequence of the letters is reversed and to allow for this the characters to be reproduced are formed on the disc 25 as shown in Fig. 2. Also as the characters at the top of the pattern appear at the bottom in the reproduction and vice versa those 31 on one side of the disc have their apices directed towards the centre 24 and are suitable for the top part of the copy, and those on the other side of the disc are oppositely directed so as to be suitable for the lower part. Circular lines to form a background or other part of the design may be formed by inserting the stylus in one of a series of depressions 36, 37 on a carriage 35 slidably mounted on a radial arm 34 rotatable on the stud 24. A spring 41 presses the carriage 35 towards the centre 24 and a fixed cam 42 engages an impact piece 40 thereon to cause the formation of wavy lines, a stop pin 43 holding the impact piece out of engagement when true circles are to be formed. Similar wavy lines may be formed by the use of a disc 44, Fig. 4, provided with guide lines as shown. In use, the required combination of characters is marked out on the disc 27 by positioning the latter to correspond with the characters 31 in turn, copying the guide lines 33, and inserting the letter in the space so formed. The disc 27 is then clamped in position by a nut 30. The disc 25 is now positioned to correspond with the design and is secured while each letter is being copied by tightening the nut 26 on the stud 24. The characters are formed by fine lines which, as also the depressions 36, 37, may be so close as to produce a solid copy.

A number stored in coded binary form is compared in a comparator 4 (Fig. 1, not shown) with the output from a counter 1 into which clock pulses are fed, a bi-stable device 3 being set to one of its stable states when the inputs to the comparator are identical so that there is no output from it and it is returned to its other state when the counter 1 reaches its maximum count. The output pulses from the bi-stable device, the length of which depends on the original number stored, are passed to an integrator 7 which produces a D.C. voltage proportional to the stored number. The apparatus may be adapted for numbers of up to 1000 by using three counters A1, B1, C1 (Fig. 3, not shown), the outputs from which are compared with the units, tens, and hundreds of the stored number, an AND gate A only being actuated to change the state of a bi-stable device 3 when there are inputs from all the comparators A4, B4, C4. The apparatus may be used to get a D.C. voltage corresponding to a number n<2> when a number n is indicated on a distributer switch 9 (Fig. 5, not shown) by connecting diodes 11 at selected cross-points of the conductors 13, 14 so that the output on the wires 14 is the square of the number indicated by the distributer switch 9, in binary coded form. The apparatus may be used as an interpolation device. A diode matrix 21 (Fig. 6) produces, for an input n, outputs n<2> and (n+1)<2> on leads 22a, 22b and 23a, 23b. These outputs are compared at gates 27, 30 respectively with the outputs from a counter 24 and passed to bi-stable devices 28, 29. The bi-stable device 29 is inhibited by the output from gate 27 so that its output is a pulse of length proportional to (n+1)<2> - n<2>. Simultaneously, a number k (less than 10) is compared with the output of a counter 31 to switch a bi-stable device 34 (as in Fig. 1), the output of which is sent together with the output from gate 29 to an AND gate 36, the output of which is thus proportional to This together with the output of bi-stable device 28 is passed to an OR gate 37, the outputs from which is sent to an integrator 38. If for example k had been chosen to be equal to 5 the output from the integrator 38 would have been the analogue of a number halfway between n<2> and (n+1)<2>.

Abstract: 649,773. Machines for making liquid-filled capsules. SCHERER, R. P. July 30, 1947, No. 20597. Convention date, June 24, 1940. [Class 87 (ii)] The pump 22, which delivers liquid between bands 34 of capsule-forming material such as gelatin, is driven in synchronism with the die rolls 20 which form capsules from the bands, and may, together with the liquid-feeding head 26, be raised above the fixed unit 18 (which includes the die rolls) by means which maintains unaltered the synchronized drive relationship between the pump and the die rolls. An electric motor 50 drives shafts 52, 54 and 62. Shaft 62 drives shaft 66 through a variable speed change-gear mechanism 64 and shaft 66 drives crank-shaft 72 which drives an adjustable-throw pump which delivers liquid from a vat 28 into tubes 24 connected to the feeder head 26. The gear mechanism 64 includes a gear wheel 194 which is slidably keyed on shaft 66 and connected by idler gear wheel 196 to gear wheel 196<SP>1</SP> fixed on the top of shaft 62. Normally the pump unit 22 rests on the fixed unit 18. The pump unit is mounted on the upper ends of two rods 182 which extend down into the unit 18. Each rod has rack teeth 184 which mesh with pinions 186 fixed to a horizontal shaft 188 having a handle 190. By rocking the handle 190 the pump unit can be raised to the position shown in Fig. 4, the shaft 66 sliding in the gear wheel 194 and the drive being maintained. The gear wheel 196 is then accessible and can be replaced by a different wheel, to alter the speed change-gear mechanism. The pump unit 22 is connected to the feeder head by two arms 174 which are pivoted on the head at 172. Each arm terminates in a sleeve 176 in which a headed pin 178 is slidable. The pins are secured at their lower ends to a plate 180 that is fixed to and forms part of the feeder head 26. This pivotal and sliding connection between the pump unit and the feeder head allows the head to adjust itself to irregularities in the operation of the die rolls. When the unit 22 is raised, the feeder head rises with it, and it is necessary to prevent liquid being pumped out into the open. This is done by byepassing the liquid so that it is confined to the pumping unit. The byepassing is effected by turning a handle (208, not shown), whereby two valves (200, not shown) are so positioned as to cut off liquid from tubes 24 and divert it back to the supply conduits in the pump unit. A vat 30 feeds liquid capsule-forming material on to casting drums 12, from which the solidified material passes over oiled rolls 16 to the die rolls 20. The drums are driven by a shaft 56 from shaft 54. The die rolls are driven by shaft 62 and the rolls 16 by shaft 60 from shaft 54. The pump is described in Specification 649,772. Specifications 395,546, 564,539, [Group VI], and U.S.A. Specification 2,288,327 also are referred to.
