Title: Additives for polyvinyl chloride moulding materials
IPC: C08L33/12
Filed: 1972-01-13
Abstract: 1365581 Polymeric additives for polyvinyl Chloride ROHM GmbH 13 Jan 1972 [15 Jan 1971] 1699/72 Heading C3P Additives for polyvinyl chloride moulding materials comprise an emulsion copolymer containing 70-95% by weight of units of methyl methacrylate and 5-30% by weight of at least one comonomer which, when polymerized alone, forms a " soft " homopolymer (i.e. has a Tg below 20‹ C.), the copolymer being in the form of a granulate whose granules consist of loosely aggregated fine particles. (The granules are distinguished from conventional bead polymer particles and are characterized by having a crumbly structure and being friable.) Suitable comonomers are esters of acrylic acid, and also methacrylate esters of alcohols having at least 4 carbon atoms; acrylates of C 1  to C 4  alcohols are preferred, particularly ethyl acrylate. The copolymer granulate is obtained by dehydrating an aqueous dispersion of the emulsion copolymer at a temperature such that no fusing or sintering of the copolymer particles occurs. Dehydration can be effected by evaporating the dispersion, e.g. in a thin layer, in a drying oven or on a roller, or preferably by spray-drying; dehydration can also be achieved by coagulating the dispersion, e.g. by electrolyte addition, and filtering off the coagulate. The copolymer additive of the invention is generally added to bulk, suspension or emulsion P.V.C. in an amount of 0À5-10% by weight (based on the total amount of P.V.C. and additive) to provide a moulding material. Fillers, stabilizers, lubricants and/or dyes may also be included.

Title: Improvements in and relating to Circuit Arrangements for Dynamic Convergence.
IPC: H04N9/28
Filed: 1967-01-13
Abstract: 1,174,444. Cathode-ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 Jan., 1967 [18 Jan., 1966], No. 1883/67. Heading H4T. Dynamic lateral convergence of the three electron beams of a colour television display cathode-ray tube is effected by subjecting each beam to the influence of a coil 24 (Fig. 7)- which may comprise the series or parallel arrangement of a separate coil for each beamconnected in series with a saturable cored inductor 25, 26 across a winding 36 on the line scanning transformer 37. In the practical application of the invention to the control of three beams the coil 24 comprises three coils 14, 15, 16 (Fig. 2), associated respectively with the green gun 13, the red gun 12 and the blue gun 11, which modulate the magnetic fields, produced via adjustable bar magnets 9, 9 in a magnetic circuit 5, 6, 7 formed as a yoke 2 about the tube neck in the vicinity of the focusing electrode g3 (Fig. 1), in accordance with a convergence correction waveform derived by the circuit of Fig. 7. The shape of such waveform is determined by the setting of potentiometer 32 which, when adjusted so that no D.C. voltage from source V is supplied across capacitor 33, the waveform is suitable for correcting convergence errors arising from the geometry of the tube (Figs. 4a and 4b, not shown), whereas when the slides of the potentiometer is adjusted to supply a positive or negative voltage the resultant waveform (due to the effect of its D.C. current on the core 26) is suitable for correcting error arising from the potential difference between the guns (positive setting of 32) or errors due to the normal deflection coils (negative setting of 32), Figs. 5 and 6 (not shown). In addition to controlling waveform shape, the amplitude of the waveform may be adjusted by differentially operative adjustable inductors 27, 28 which allow the current flowing in coil 24 to be varied whilst maintaining the current in inductor 25 at a constant value. If the misconvergence departures occur in the opposite sense to that depicted in Figs. 4 to 6 (not shown), the correction waveforms may be reversed in phase (180 degrees phase change) by the change over connections 45, 46. The lateral convergence circuit of the present inven tion is utilized in conjunction with a known type of static and dynamic radial convergence correction arrangement 3, Fig. 1.

Title: Control apparatus for use in the manufacture of rope or tow
IPC: B65H63/032
Filed: 1965-01-15
Abstract: 1,088,770. Inspecting ropes and tows; alarm signals; counting faults; stop motions. E. I. DU PONT DE NEMOURS & CO. Jan. 15, 1965 [Jan. 15, 1964], No. 1991/65. Headings D1F and D1T. The invention utilizes a plurality of photosensitive devices to scan a rope or tow during manufacture, and control means responsive thereto to:- (a) operate machine stop and break signalling means on detection of a break in the rope or tow; (b) detect, count and signal transient splitting or momentary loss of section; and (c) predict an impending serious malfunction on the basis of flutter frequency and to operate stop means when the flutter frequency exceeds a predetermined level. In Fig. 3 three light sources 104 (only one is shown) illuminate spaced apart lenses 106, 106', 106" cooperating with three photosensitive devices 108, 108', 108" (only 108 is shown) connected in parallel. A complete break resulting in absence of material between the light gap causes all three photosensitive devices to change to their low resistance state and so cause a substantial pulse to pass over line 14 to a preamplifier and various subcircuits. Loss of part of the rope or tow will cause one or more of the sensors 108, 108', 108" to receive sufficient light to switch to a lower resistance state but this will result in a lesser current flow than when all the sensors, are receiving light. Similarly a lateral vibration of the rope or tow will cause pulses of current having varied durations and frequencies of occurrence that are utilized to operate stop means at preselected frequency level. Should the rope or tow break above the sensing means, the broken material will pile onto a plunger 12, depression of which stops the machine. The control apparatus includes first electrical means that is responsive when all of the sensors receive light, and second electrical means that is responsive when only some of the sensors receive light, the first means comprising a preamplifier providing an output signal to an amplifier-relay operative on an extended signal from the sensors, and including third means responsive to another output sigrial from the pre-amplifier, which third means comprises a first thyratron adapted to fire on any signal from the pre-amplifier, and signalling means responsive to an output signal from the thyratron, and wherein the second means is responsive to another output signal of predetermined polarity from the thyratron and comprises a second thyratron subject to a predetermined grid bias of polarity opposite to said predermined polarity, said second thyratron being adapted to fire upon lowering of its grid bias to a predetermined level by successive output signals from the first thyratron, and relay means operative upon firing of the second thyratron.

Title: Improvements in or relating to a shutter mechanism for photographic apparatus
IPC: G03B9/22
Filed: 1928-01-24
Abstract: 284,329. Wolf, J. Jan. 29, 1927, [Convention date]. Shutters.-In a shutter provided with a delay mechanism which determines the commencement of the running down movement of the spring barrel 5, Fig. 1, when wound (as in Fig. 2), a locking lever 8 is provided which can be held by the delay mechanism B so as to hold the barrel 5 for a predetermined time immediately after the barrel 5 is released from the holding lever 4 which is operated by the shutter trigger 1. The barrel 5 operates the shutter leaves on running down in a clockwise direction by means of a shaped end 6<a> of a crank arm which engages a pin 6<c> on a sector 6 directly operating the blades, the crank arm being kept out of action on winding the barrel by a pin 6<e> acting on a shaped part of the crank arm. Both levers 4 and 8 are mounted on the same pivot 4a. The lever 4 is moved by a spring 4<b> behind the end of the flange 5a of the barrel when the latter is wound. One end of the lever 8 has a sloping surface which also can engage the end of the flange 5a. When the mechanism B is unwound a nose on the pawl 9 drops into a slot 10<a> in the disc 10 and the pawl does not engage the lever 8 so that the other end cannot hold the barrel 5 when released from the lever 4. When, however, after winding the barrel 5, the mechanism B is wound. the pawl 9 is forced out of the notch 10<a> by a sloping face thereof and locks the end of the lever 8; also the delay mechanism is held wound by a pawl 11 which has been moved into operative position by the pin 4<c> on the lever 4 when the latter springs behind the end of the flange 5<a>. The same movement of the lever 4 has also caused a nose 4<e> to retract a spring arm 30 on which the delay escapement 29 is mounted. On now returning the shutter release 1, the lever 4 releases the barrel 5, which is however immediately held by the sloping end of the lever 8, the other end of which is locked by the pawl 9; also by the movement of the lever 4 the arm 30 has been released and the delay mechanism is then also released from the holding pawl 11. The barrel 5 is held until the notch 10<a> comes opposite the nose of the pawl 9. Specification 284,351, which describes a particular construction of shutter with delay mechanism, is referred to.
