Title: Process for the electrical deposition of synthetic resin coatings
IPC: C09D167/08
Filed: 1963-10-31
Abstract: In coating metallic or other conductive supports with synthetic resins by anodic electro-deposition from aqueous organic solvent solutions at elevated temperature of synthetic resins of acid number above 10 made water-soluble by treatment with ammonia, an aliphatic amine, or a quaternary ammonium derivative of such amine to render it non-acid, the coating bath is regenerated by adding water and an un-neutralized solution of the resin in a water-miscible solvent. Typically the coating baths are those described in the parent Specification and are maintained at 40-60  DEG C. and are used to coat anodically metal or metal alloy or phosphated metal or metal alloy supports as of foil, strip or wire with constant current density by applying an increasing potential up to 250 volts, the coatings being hardened by heat-treatment at 80-220  DEG C.

Abstract: 1,207,620. Inhibiting foam formation. HERCULES Inc. 11 Sept., 1968 [13 Sept., 1967; 23 July, 1968], No. 43268/68. Headings C3P and C3R. Foam formation in an aqueous system having foam-forming tendencies is controlled by adding to the aqueous system a foam-controlling amount of a stable dispersion comprised of (A) at least one normally solid hydrophobic thermoplastic synthetic polymer in finely divided form as the dispersed phase and (B) an organic liquid as the continuous phase, the organic liquid being a non-solvent for the hydrophobic synthetic polymer(s). The polymer (A) may be a normally solid homopolymer derived from an α-monoolefinic hydrocarbon having 2-20 carbon atoms, copolymers (including graft polymers, addition polymers and block polymers) of these monomers, copolymers of these monomers with butadiene, polybutadiene, polyisoprene, polyethylene terephthalate and nylon 6, nylon 6/6 and nylon 6/10. The polymer particles are of an average primary particle size within the range 0À02-50 microns and comprise between 2 and 25% by weight of the dispersion. Many organic liquids (B) are particularly mentioned including non-polar and water-immiscible polar organic liquids. The dispersion may include 0À01-10% by weight of a surface active agent, of which many are particularly mentioned. The dispersion itself may amount to between 0.003 and 1% by weight of the aqueous system to which it is added. Examples are directed to controlling the foaming of aqueous solutions of alkyl benzene sodium sulphonate or black pulp mill liquor encountered in paper-making, with the aid of dispersions containing: (2 and 3) finely divided polypropylene in xylene or in a commercially available mixture of aromatic hydrocarbons containing a small amount of 2-ethyl hexanol to wash the polypropylene particles; (4-7) finely divided polypropylene, polyethylene, copolymer of propylene and ethylene, or polyethylene terephthalate in white mineral oil (mixture of aliphatic hydrocarbons), with optionally sorbitan monooleate; and (8-11) finely divided polyethylene in heptane and, optionally, silicone oil, sorbitan monooleate, or sorbitan monooleate and the polyoxyethylene adduct of sorbitan monooleate.

Title: Brake operating mechanism
IPC: F16D55/30
Filed: 1962-11-23
Abstract: 957,598. Disc brakes; fluid-pressure brakes; slip couplings. FAWICK CORPORATION. Nov. 23, 1962 [Dec. 1, 1961], No. 44395/62. Headings F2E, F2F and F2U. A brake - operating mechanism comprises constant - stroke actuating means for moving brake-operating means in opposite directions to apply and release the brake, the actuating means having a constant stroke in either direction of movement of the operating means. As shown, the operating mechanism is applied to a disc brake comprising an axially movable disc 10 and pads 16, 17 held in a calliper 12. Pad 17 is fixed in place and is provided with a back-up plate 18 held in place by a plate 19. Pad 16 is axially movable towards and away from the disc by means of a plunger 54 and is guided by surfaces on the calliper and a guide plate 21. Both pads which are removable radially outwards are retained in place by a U-shaped bracket 25. The actuating means is spring-applied and fluid-pressure released (or vice versa) and comprises a piston 35 which when moved to the left by the spring 36 on release of fluid-pressure through port 39 rotates a gear member 47 by means of rack teeth 45. The constant stroke of the piston is between the abutment 37 for the piston face and the end wall 41 acting as an abutment for the sleeve 40 carried on the piston-rod. Rotation of the gear member 47 causes it to advance axially towards the disc due to the teeth on the extension 48 thereof engaging with the teeth 49 on a stationary nut 50. Plunger 54 is also rotated and moved axially by means of spaced friction plates 57, 58 splined thereto engaging a frictional driving disc 59 bolted to the gear member 47 so as to apply the pad 16 against the disc. If the pad is applied before the piston 35 has completed its stroke the gear 47 continues to rotate with respect to the plunger 54 which remains stationary due to the threaded connection 64, 65 between the two, the friction clutch 57, 58, 59 slipping. Wear adjustment is effected by a one-way brake 95, 85. On application of the brakes the plunger 54 rotates a plate 85 splined thereto which in turn drives a clutch plate 90 by means of a friction plate 89 held in place by a back-up plate 88. An extension 90a abuts a fixed pin 99 and if adjustment is required causes plate 90 to slip with respect to plates 85, 89, a cam 95 mounted on the extension 90a slipping on the periphery of the plate 85. On release of the brake the plate 85 rotates in the reverse direction with the plunger 54 and plate 90 also rotates until the extension 90a abuts a fixed pin 98. Cam 95 then acts as a positive brake on the plate 85 so that plunger 54 is held a predetermined fixed axial distance from the disc. The gear 47 will then rotate with respect to the plunger to allow the piston 35 to complete its constant return stroke.

Abstract: 1277498 Carbon articles GULF OIL CORP 22 Sept 1969 [3 Oct 1968] 46483/69 Heading C1A An article having high strength characteristics comprises an article made of graphite or a refractory material having a coefficient of thermal expansion between 6 to 9 Î 10<SP>-6</SP>/‹ C. having a coating of pyrolytic carbon surrounding it, said pyrolytic carbon being deposited at atmospheric pressure and at a temp. of at least 1200‹ C. such that the deposited carbon has a density of at least 1À5 g./c.c., its coefficient of thermal expansion being less than that of the substrate material so that as a result of the thermal contraction occurring during the cooling of the coated article from deposition to ambient temperature the pyrolytic coating is placed under compressive stress. Preferably the compressive stress is at least 5000 p.s.i. and the thickness of the carbon coating is at least 25 microns. The pyrolytic carbon deposit may be isotropic, or laminar and may have an apparent crystallite size not greater than 50 Š. Isotropic carbon is defined as that which possesses very little preferred orientation, has a broad range of apparent crystallite size, a density varying from 1À4 to 2À2 g./c.c. and a structure which when viewed metallographically under polarized light is not optically active. Laminar carbon is defined as that carbon possessing layer planes orientated parallel to the substrate surface, also having various apparent crystallite sizes, a density ranging from 1À5 to 2À2 g./c.c. and a structure which when viewed metallographically under polarized light is optically active showing a typically "cross-pattern". The isotropic carbon deposit may have a Bacon Anisotropy Factor of not greater than 1À1. The deposited carbon may have a carbide, e.g. silicon carbide, dispersed throughout. The carbide may be produced by introducing a carbide forming material, e.g. a volatile Si compound, into the atmosphere of carbonaceous gas and inert gas used to to deposit the coating.

Abstract: 1277221 Continuous rod cut-off AMF Inc 23 Sept 1969 [2 Oct 1968] 46787/69 Heading A2C Apparatus for severing continuous cigarette rod fed along an axis 1, Fig. 3, comprises a pair of shafts 3, 4 whose axes are parallel and offset and lies in a plane parallel to that containing the rod axis, a disc 13, 14 secured to each shaft, at least one drag link 12 interconnecting crank pins 113, 114 on the discs, and a cutter blade 16 carried by the or each drag link. In the embodiment there are three drag links interconnecting three equally spaced crank pins on each disc whereby rotation of the shaft 4 by a gear 15 is transmitted to the disc 13 and the orientation of the cutter blades remains unchanged during the rotation. The shafts are carried by a member 8 which is rotatably adjustable on a bracket 9 to vary the angle of the shafts relatively to the rod axis 1 so that the horizontal component of velocity of the blades in the cutting region can be made to correspond to the linear velocity of the rod, and the blades are angularly adjustable on the drag links so that they may be set normal to the rod axis. To compensate for reduction of the radial projection of the blades due to sharpening in use, the blades are also adjustable by a screw and nut mechanism which may be controlled automatically. When adjustment is required, a spring-loaded pneumatic or hydraulic piston (not shown) in each drag link is displaced to cause a rack 26, Fig. 4 to turn a pinion 22 which, through a one-way drive 23, turns a nut 19 coacting with a screw 18 to cause an incremental advance of the blade. A second one-way device 24 between the nut and a housing 112 prevents rotation of the nut when the piston is returned in preparation for the next adjustment increment. A manual knob 118 provides for initial adjustment. (For Figures see next page)
