Title: Manufacture of electrically conductive plastics articles
IPC: C08K3/02
Filed: 1976-02-09
Abstract: 1479569 Moulding electrically conductive plastics INTERNATIONAL BUSINESS MACHINES CORP 9 Feb 1976 [17 March 1975] 04915/76 Heading B5A [Also in Divisions C3 and C7] An electrically conductive article of thermo- or thermosetting plastics, is made by vacuum depositing a ductile metal coating on to granules of the plastics, and heat plasticizing the coated granules during delivery to an orifice by an impeller, so that the coating is disrupted during delivery, into fragments which are formed into strands on passing through the orifice, and then moulding the strand containing plastics. The vacuum deposited layer is of 1500 to 3000, and preferably of 2000 to 3000 Angstroms thickness. In the Examples: (1), polycarbonate pellets coated with aluminium were injection moulded in apparatus comprising a screw impeller delivering into the injection mould; (2), nylon monofilament coated with copper was chopped into short sections which were extruded, by a rheometer, into an extrudate which was chopped and then compression moulded. The granules may also be moulded by a plunger transfer process. The metal coating is deposited on the granules 21, Fig. 1, within a housing 13 in which clips 17 of the metal to be evaporated are melted, on a heated wire 14 along which the molten metal spreads to be evaporated, the granules 21 being contained in a bowl 19 which vibrates to displace the granules along a ramp to the top of the bowl, to bounce across a vibrated table 23 and return to the bowl.

Title: Improvements in or relating to fabric-covered aircraft components
IPC: D06N3/02
Filed: 1943-03-29
Abstract: Fabric-covered aircraft components are made by stretching over an aircraft component or frame a fabric discontinuously coated with a cellulose derivative composition, and applying a solution of a cellulose derivative in an organic solvent which is also a solvent for the cellulose derivative in the discontinuous coating, thereby rendering the discontinuous coating continuous and tautening and shrinking the fabric around the component; The discontinuous coating is produced by applying to the fabric an aqueous emulsion of a cellulose derivative in which the disperse phase is a solution of the cellulose derivative in a water-immiscible solvent optionally containing a proportion of water or other non-solvent.  The total proportion of water and other non-solvent is sufficient to outlast the volatile solvents during evaporation and the emulsion is substantially free from resin and wax.  The aqueous emulsion may comprise a solution of cellulose nitrate in butyl alcohol, butyl acetate, methyl ethyl ketone, castor oil, and water emulsified in water containing small amounts of polyvinyl alcohol, isopropyl naphthalene sulphate, and petroleum naphtha, or a solution of cellulose nitrate and tricresyl phosphate in methyl ethyl ketone, toluol, and water emulsified in water with the aid of polyvinyl alcohol and isopropyl naphthalene sulphate.  A fabric coated with the emulsion, dried and stretched over a frame, is shrunk and tautened by applying two or more coats of a composition containing nitrocellulose, castor oil, dibutyl phthalate, pigment, ethyl alcohol, methyl ethyl, ketone, ethyl acetate, butyl acetate, butyl alcohol and petroleum naphtha.  Ethyl cellulose, cellulose acetate, and mixed esters such as cellulose aceto-butyrate and cellulose acetopropionate may also be used as the cellulose derivative, and methyl isobutyl ketone as a solvent.  The emulsion may contain a small proportion of an insolubilising agent such as stearato chromic chloride described in U.S.A.  Specification 2,273,040.  The fabric may be wetted with water before applying the emulsion and the dried emulsion coating may be polished by hot-calendering.

Abstract: 1424632 Winding machine; thread supply and tensioning W & M OSTERMANN 4 Feb 1974 [16 Feb 1973] 05083/74 Heading B8G [Also in Division D1] In a winding apparatus for sheathing material and comprising a rotatable, vertical winding plate having bobbin-carrying spindles and bobbin brakes, threads from each spindle are formed into a loop and tensioned by a respective pivoted, spring-biased arm, and a sensing roller on a bobbin brake actuating arm contacts one side of the thread loop. In a winding or braiding machine, Fig. 1, thread supply units 20 are mounted on rotatable plate 11 to deliver strand to, and sheath, running tubing 15. Each unit 20 comprises, Fig. 3, bobbin-supporting spindle 26, disc brake 30 applicable to the bobbins, and strand tensioner 24. A strand of the threads runs in the tensioner over fixed rollers 43, 44 and then runs in a loop about rollers 46, 47. Roller 46 is mounted on pivotable arm 45 which is biased by an adjustable tension spring in the direction 73 to tension the strand. One leg of the strand loop engages roller 42 on arm 37 which is pivotable about pivot 39 to apply brake 30 via pivot 36. If strand tension increases, Fig. 4, arm 45 is pivoted upwards against spring bias and the force imparted by the strand leg to arm 37, and hence the brakeapplying force, is reduced as the angle a approaches 180 degrees. When a minimum length of thread is stored in the loop, surface 81 on arm 45 engages roller 79 on arm 37 to lift the arm to ensure positive brake release. A minimum gap between rollers 42, 46 is maintained. In the braiding or winding machine, Fig. 1, each lever 37 extends radially of the plate and, in a non-braking position, parallel to the plate.

Title: Improvements in or relating to roll film photographic cameras
IPC: G03B17/30
Filed: 1940-03-21
Abstract: 535,502. Roll-film cameras. KODAK, Ltd. March 21, 1940, No. 5285. Convention date, June 9, 1939. [Class 98 (i)] In a roll-film camera having means to prevent reverse movement of the film strip except when the winding knob is displaced axially to allow re-winding, the means preventing the reverse movement is mounted on the winding shaft and moves with it when it is displaced axially. As shown, the take-up member consists of an outer member 19 connected by a known slip clutch device to an inner shaft 20, to an extension 21 of which the winding knob 24 is secured. Reverse rotation of the knob is prevented by one or more spring pawls 46 attached to its underside and engaging ratchet teeth on the face of a disc 52 loosely mounted on a reduced portion of the shaft extension 21. Pins 56 depending from the disc into apertures formed in the camera wall hold the disc against rotation but allow it to move axially with the shaft 21. When the knob 24 is moved outwardly, as shown in Fig. 7, a pin 34 on the shaft extension 21 is disengaged from a recess 33 on the hub of a gear 31 loosely mounted on the shaft and connected by an idler 29 to a gear 28 on the film sprocket shaft 27. The latter shaft is therefore free to rotate, allowing the film to be rewound. When the knob is pushed in, the pin 34 locks the gear 31 to the shaft extension 21, so that the sprocket shaft 27 is rotated with the shaft 20, and reverse movement is prevented by the pawls 46 and ratchet 52. The arrangement of the pawl and ratchet device as a unit movable with the winding shaft allows the film to be rewound without turning the winding knob backwards and prevents axial thrust by the pawls tending to move the knob outwardly to the rewind position. When the film has been wound on through an image length by one revolution of the sprocket shaft a pin 39 on the underside of the gear 28 moves a pawl 36 to engage a ratchet 35 secured to or integral with the gear 31 and locks the winding shaft. In order to wind on the next picture area the shaft 37 on which the pawl 36 is carried is moved axially by pressure on an external button to release it from the pin 39, when it is turned by a spring 42 to release the ratchet 35.

Abstract: 658,681. Roller shutters. MATHER & PLATT, Ltd., and McCLENAN, F. Feb. 28, 1949, No. 5355. [Class 20(iii)] In an electrically operated rolling shutter having also hand operating means, means are provided which automatically disconnect and hold disconnected a clutch (through which hand operation is effected) when the shutter is being operated electrically, the clutch being at all other times held in its closed or service position. As shown the manual drive is from a chain c to a wheel d loose on the shaft b operating the shutter, the wheel carrying a half clutch e operated by a lever g pivoted at h. During electric operation, an energised solenoid k, m, swings the lever counterclockwise against the force of a spring i to hold the half clutch e out of engagement with the other clutch part f fast on the shaft. In this position the lever also closes a switch a in the motor circuit. When the motor is cut out by limit switches at either end of the movement of the shutter the solenoid is de-energized and the spring i causes the two clutch parts to engage and remain in engagement thereby leaving the manual drive coupled up. The solenoid k, m remains de-energized until the next operation of the motor control buttons.
