Title: Improved coating and adhesive compositions
Inventor: AITKEN ROXBURGH RICHMOND
IPC: F16L59/02
Filed: 1958-11-05
Abstract: A composition of polyvinyl chloride and a polyisocyanate or a substance capable of behaving as a polyisocyanate when heated and an isocyanate-reactive polyester which is completely liquid above 20 DEG C. and preferably above 15 DEG C. is used for coating articles made from natural or synthetic rubbers, polyvinyl chloride, polyamides, polyethylene, polypropylene, polytetrafluoroethylene, polyethylene terephthalate, melamine-formaldehyde, urea-formaldehyde, phenol-formaldehyde resins, leather and wood. In an example a polyester from 1:5-pentanediol, glutaric acid and adipic acid is reacted with 2:4-tolylene diisocyanate, glycerol and diethylene glycol in ethyl acetate.  The reaction product (A) is mixed with polyvinyl chloride, calcium stearate, tritolyl phosphate and more polyester to form a plastisol.  A cleaned cast polyurethane rubber is painted with the plastisol, further coats of plastisol from which (A) is omitted are applied, and the coating is gelled at 170 DEG C. Specifications 804,839, 807,243 and 842,154 are referred to.ALSO:The invention comprises a composition of polyvinyl chloride and a polyisocyanate or a substance capable of behaving as a polyisocyanate when heated and an isocyanate-reactive polyester which is completely liquid above 20 DEG C. and preferably above 15 DEG C. The polyester is defined as one which is obtained by the condensation of straight-chain aliphatic a ,o -diols and straight-chain aliphatic a ,o -dicarboxylic acids, optionally with up to 20% molar of other diols and dicarboxylic acids, the reagents being chosen so that in the polyester produced the ratio of the total number of carbon atoms present to the total number of oxygen atoms is at least 5 to 2.  As compounds which behave as polyisocyanates when heated there may be used the isocyanurate polymers described in Specification 809,809. As coatings the compositions can be applied in a solvent, the isocyanate being added immediately before application.  Alternatively the polyester and polyisocyanate may be added to a plastisol or organosol of the polyvinyl chloride.  The compositions can also be used for bonding polyvinyl chloride to other materials such as leather and metals.  In examples a polyester which is liquid at temperatures above 13,5 DEG C. is prepared from 1:5-pentane diol, glutaric acid and adipic acid and reacted with 2:4-tolylene diisocyanate, glycerol and diethylene glycol in ethyl acetate to give a reaction product (A) containing 75% solids.  A plastisol is prepared of paste-making vinyl chloride polymer, calcium stearate, tritolyl phosphate, polyester (as used in making product (A)) and the reaction product (A) itself.  The plastisol is used for coating polyethylene terephthalate fabric (see Group VIII). Specifications 804,839, 807,243 and 842,154 also are referred to.

Title: An improved system of simultaneous and synchronous remote control for movable shafts
IPC: G05D3/14
Filed: 1920-12-18
Abstract: 155,586. Soc. des Etablissement Gaumont. Feb. 18, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Hunting control systems.- In a system of simultaneous and synchronous remote control of moving shafts &c., use is made of two-pole electric motors whose field-magnets A, B, C, D are excited by single-phase alternating current. The armatures a, b, c, d are tapped at equidistant points and connected to slip rings e<1>, f<1>, g<1> - - e<4>, f<4>, g<4> each motor having the same number of slip rings, and corresponding rings being connected together by the conductors H. Some or all of the motors carry commutators on which bear the brushes l<1>, m<1>, n<1>, p<1>, &c. which are insulated from each other. By short circuiting a pair of brushes (say l<1>, m<1>) the first motor becomes a repulsion motor and rotates at a speed depending on its regulation, the others rotating synchronously. To reduce the speed of working, the short circuit may be replaced by a resistance, but as this also reduces the torque a preferable means. is to make the short circuit intermittent by any form of interrupter but preferably that shown in Fig. 2. On the closing of the key 17, current flows through the winding 10 via the contact 8 and the armature 15 makes the contacts 11, 12. The current then flows via the contact 12 through the coil 2, and the armature 3 breaks the contact at 8. Current continues to flow in the winding 10 however through the contacts 11 and 9 until the latter is broken by the contact of the pieces 6, 7. Both magnets are then de-energized and the parts returned to normal by the springs 5, 14, 16. The intermittent short circuit of the motor brushes is provided by the surfaces 6, 7. In the application of the invention to transmitting the movements in a horizontal plane of one telescope to a number of indicators, the telescope is mounted on a vertical shaft carrying four slip rings connected to the motor brushes, and a horizontal plate. Four semicircular contacts on the plate are separated by insulation and each is connected to one of the slip rings. A pair of brushes geared to the motor short circuits a pair of these contacts except when bearing on the insulation. When the plate is rotated by movement of the telescope, the motor rotates until the brushes bear on the insulation,. and causes an equivalent rotation on the distant motors to which it is connected as shown in Fig. 1. Further modifications are described for securing greater accuracy in the reproduction of the motion of the telescope.

Abstract: 925,372. Sewing-machines. A. VIGORELLI FABBRICA MACCHINE PER CUCIRE S.p.A. Oct. 21, 1959 [Oct. 21, 1958], No. 35680/59. Class 112. A sewing-machine having a plurality of coaxial cams driven together by a step-by-step drive for automatic cyclical control of the needle bar oscillating means, feedadjusting means, and lateral shifting of the work table, has operatorcontrolled means for varying the amplitude of the steps imparted to the cams by the said drive. The cams 23 are detachably engaged with a tubular shaft 24 integral with the driven portion 28 of a uni-directional roller clutch whose driving portion 29 is oscillated by a link 44 from a traveller 42 slidably mounted on a pivoted member 39 oscillated by the main shaft 34. The position of the traveller on its rod 41, and hence the amplitude of the movement of clutch portions 28, 29, is manually variable, through linkage 49, 50, by a knob 47 on a shaft 48. Needles shifting laterally, multiple needle machines.-A pivoted device 35, integral with a fork 33 engaging a rotating cam 32, has a traveller 37 slidably mounted on a rod 36 and pivoted to a connecting-rod 38 included in a linkage (not described) for lateral oscillation of a needle bar adapted to carry one or more needles. Movement of the traveller 37 along its rod to vary the amplitude of oscillation is effected by linkwork comprising link 93, lever 92, link 90 and the follower lever 88 which engages a surface 56 of one of the cams. An eccentric 97 may be manually operated by a knob 95 to engage the lever 92 to limit its motion. The mechanism can be disengaged by rotating a knob 99, to swing lever 101 anticlockwise, the link 102 then moving the upper end of link 90 along the slot 104 in lever 92 to raise the lever 88 from the surface 56. Feed by dogs, reversing and regulating.-A second cam 52 of the group 23 co-operates with a follower comprising a two-armed lever 62, 63 to lift a link 67 connected to mechanism (not shown) controlling the amplitude and direction of feed dog movement. The lever 62, 63 is pivoted at 64 to a plate 72 itself pivoted at 73 and manually rotatable about that pivot by a knob 78 and lever 76 to disengage the follower from the cam 52. Manual operation of a knob 68 rotates an eccentric 70 which engages the lever arm 63 to adjustably limit the movement of the lever. Zig-zag feed.-A cam groove 54 in cam 52 engages a pin in one arm of a two-armed lever 80, 81 connected to a laterally shiftable workplate (not described) in which the feed dog is guidably carried. A manually-operated knob 85 is connected by means 82, 83, 84 to workplate amplitude adjustment means (not described). Frames.-The manually-operated knobs are located in a front panel 21 formed on the front face of the machine and provided with a hinged door 22 located in front of the removable cams.
