Title: Improvements in or relating to pulleys
IPC: F16H55/56
Filed: 1963-10-14
Abstract: 1,056,752. Expanding pulleys. SOC. INDUSTRIELLE DE TRANSMISSIONS. Oct. 14, 1963 [Oct. 12, 1962], No. 40427/63. Heading F2D. An expanding pulley has its flanges adjusted axially by screw-and-nut means actuated manually, and has locking means preventing undesired movement of the flanges. A flange 3 is adjusted axially relatively to a flange 2 by a nut 6 which is fixed axially relative to the flange 3 and is non-rotatable, being in splined engagement with a fixed member 22. The nut 6 cooperates with a screw 5 which is rotatably mounted with respect to the flange 2 but fixed axially relative thereto and which is fast with a plate 10 having locking members 11, 12 pivotally mounted thereon. The locking members 11, 12 have ends 11 1 , 12 1  urged together by a spring 13 and engageable in a groove 14 of a part 15 which is fast with the fixed member 22. a hand wheel 7 has a pin-and-slot connection with the plate 10 to give slight rotational play and has a finger 18 extending between the ends 11 1 , 12 1  of the locking members and has bars 19, 20 adjacent ends 11 2 , 12 2  of the locking members. On rotating the hand wheel, finger 18 engages the end 11 1  or 12 1  of one of the locking members and releases it from the groove 14. If the resisting torque of the screw is weak, it begins to rotate and the second catch continues to engage frictionally in the groove, thus creating a residual braking torque, which is limited since in that direction it does not lock. If the resisting torque of the control screw is considerable, the bar 19 or 20 causes the second locking member to release as well. At this point the lost motion in the pin-and-slot connection between the wheel 7 and plate 10 is taken up and the screw 5 is rotated. The fixed member 22 is connected by linkage to a fixed member such as the frame of a machine or to the ground. The locking members 11, 12 prevent movement of the screw 5 except when the wheel 7 is rotated. Indication of the adjustment is obtained by two scales, one indicating revolutions of the wheel and comprising a bar 26 on the nut 6 which co-operates with a scaled axial aperture in a collar 23 connecting the member 15 to the fixed member 22, and a fine scale indicating fractions of a revolution and comprising a circular scale fast with the plate 10 and co-operating with a transverse aperture formed in the collar 23. The screw 5 and nut 6 are respectively mounted on the flanges 2, 3 by ball bearings 9, 8 to which lubricating grease may be admitted through nipples 33, 32. The flange 2 is fixed on a spindle 1, and the flange 3 is axially slidably keyed thereto.

Title: Polyether elastomers
IPC: C08G65/12
Filed: 1961-11-14
Abstract: The invention comprises vulcanizable polyether elastomers composed of polymerized epoxide monomers of which at least 50 mol per cent is styrene oxide or an alkylene oxide having not more than four carbon atoms, or a halogenated derivative of alkylene oxides, the elastomer being substantially amorphous, devoid of spherulite, and having an intrinsic viscosity greater than 3.0. They are prepared by polymerizing in the presence of zinc diethyl and water, either in the absence of a diluent or in presence of one of the following: benzene, toluene, xylene, or mixtures thereof with or without a minor portion by volume of a liquid aliphatic hydrocarbon diluent, benzaldehyde, an alkaldehyde with 2 to 7 carbon atoms, or mixtures thereof, with or without dilution with dioxane or a liquid aliphatic hydrocarbon. The mole ratio of water to zinc diethyl is in the range 0.5 to 1.5:1, preferably 1:1. Specified monomers are ethylene oxide, 1,2-propylene oxide-chloropropylene oxide 1,2-butylene oxide, 2,3-butylene oxide, isobutylene oxide, styrene oxide, and mixtures thereof. A minor portion, preferably 3.5 mol per cent, of an olefinically unsaturated epoxide can be added and copolymerized with the above oxides. Specified unsaturated epoxides are 1-butene-glycidyl ether, vinyl-glycidyl-ether, vinyl-thio-ethyl-glycidyl ether, glycidyl acrylate, glycidyl methacrylate, butadiene monoxide, vinyl-cyclohexene monoxide, allyl-glycidyl ether, and mixtures thereof. Preferably 1.3 moles of zinc diethyl per 100 moles of monomer is used, but as little as 0.2 moles is required. Vulcanization of the saturated elastomer is effected by a mixture of an organic peroxide and a conventional sulphur-bearing agent. In the case of polyethers containing unsaturation a single agent is sufficient. Specified peroxides are di-cumyl peroxide, di-tertiary-butyl hydroperoxide and 2,5-bis (tert.-butyl-peroxy)-2, 5-dimethyl hexane. The examples describe the preparation of: (1) poly-propylene oxide; (2) copolymer of propylene oxide and allyl glycidyl ether; (8) copolymer of propylene oxide and butadiene monoxide; (9) copolymer of propylene oxide and vinylcyclohexene monoxide; (10) copolymer of propylene oxide and glycidyl acrylate; (12) polymer of styrene oxide; (13) polymer of butylene oxide. In examples (18)-(20) poly propylene oxide is vulcanized in presence of various quantities of di-cumyl peroxide, sulphur, phenylb -naphthaline (as antioxidant), and carbon black (as reinforcing agent). In example (21) copolymer of example (7) is vulcanized in presence of sulphur, stearic acid, zinc oxide, carbon black, tetramethyl thiuram disulphide and tellurium diethyl dithiocarbonate (the latter two being accelerators). Properties of the rubbers are also shown in the examples, and a comparison table of rubber of example (21) and several other known rubbers is given.

Title: Lvehicle lighting systems
IPC: B60Q1/44
Filed: 1972-09-05
Abstract: 1445569 Road-traffic signalling LUCAS ELECTRICAL CO Ltd 22 Aug 1973 [5 Sept 1972] 41062/72 Heading G4Q In a circuit which includes a dimming resistor 19 in series with a vehicle stop lamp when lighting switch 12 is closed, a current sensitive means is operable when stop lamp switch 17 is closed to short-circuit the dimming resistor, the current flowing through the sensitive means decreasing when the stop lamp is hot to remove the shortcircuit. Lag in stop lamp illumination at night (due to the dimming resistor) is thereby reduced. In the embodiment a relay has a winding 34 and normally closed contacts 36, 37, 38. A further relay winding 18 is provided: when switch 17 is closed current through winding 34 is insufficient to illuminate any of front 25, 27 and rear 26, 28 direction-indicating lamps but is sufficient to cause contacts 36, 37 and 38 to open. When stop lamp switch 17 is closed current through winding 18 opposes winding 34 and contacts 36, 37 and 38 all close. As stop lamps 21, 22 heat up their resistance so increases when hot that the current in winding 34 causes contacts 36, 37, 38 to open. Resistor 39 ensures that flasher 23 frequency does not change when resistors 29, 31 are in circuit. Modifications.-(1) Instead of winding 18 opposing winding 34 it could operate its own normally-closed contact in parallel with contact 36. (2) Diodes 32, 33 are omitted, the end of winding 34 connected thereto is earthed and operates a contact in the series circuit between the junctions resistor 29/lamp 25 and resistor 31/ lamp 27, the series circuit including another relay winding which operates contacts 37, 38.

Title: Non-run reversible looped fabric and method of making the same
Inventor: COREY ROBERT JOSEPH
IPC: D04B1/06
Filed: 1967-09-12
Abstract: 1,206,144. Producing looped fabric. R. J. COREY. 12 Sept., 1967, No. 41632/67. Headings D1C and D1K. A simulated knitted tubular fabric consists of interlooping a yarn or yarns so that the loops of each course pass behind one leg and in part of another leg of each preceding and succeeding course as shown in Fig. 10. Such a fabric has considerable run resistant properties in the event of a loop breaking. In that figure it can be seen that with the aid of bars 149a. 149c a bobbin containing the yarn can be continuously looped about the bars and existing loops on the bars to produce the fabric. Reinforced areas can be produced by introducing an additional yarn to be looped with the base yarn. Bulge effects can also be produced by increasing and decreasing the number of loops in any one course or by introducing short-courses. Alternatively the fabric can be produced on a frame Fig. 12 consisting of bars 184, 186 about which the selvedge threads 151 are secured and in between which end over and under the bars 184, 186, other yarns are wound. By using one or two hand operated latch needles 175 in opposite directions in alternate courses the yarns are successively looped about each other. A bar 153 having pins 152 holds the loops down as each course is produced. To produce reinforced areas additional yarns can be wound about pins in the bar which hold the yarns in position until they are incorporated in the looped structure. By shaping the bars and making them relatively adjustable in addition to having a pin bar with insertable pins as shown in Fig. 18, stockings having shaped and reinforced areas can be produced. The fabric may be of a similar nature to that disclosed in Specification 1,206,145 but it must be manufactured in tubular form. The final row of loops are locked in position by a binding thread which is looped and drawn around the loops of the final row and tied to prevent the row unravelling.

Abstract: 1304567 Colour television tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Sept 1970 [6 Sept 1969] 42247/70 Heading H1D In a colour television tube wherein a shadow mask is supported in a faceplate by means of resilient members attached to the mask and provided with an aperture or a stud adapted to engage a stud or an aperture on the faceplate, the stud being circular and the aperture a rounded triangle, deformation and consequent rigidity may be caused by the shrinking of the aperture over the stud on cooling from the high temperature employed in processing the tube; this effect is avoided by employing for the member in which the aperture is formed a material having a thermal expansion coefficient equal to or lower than that of the material used for the stud. In one arrangement (Fig. 4, not shown) each resilient member is a bimetal strip and the aperture is provided in the strip of lower thermal expansion coefficient. In other arrangements each resilient member is of chromium-nickel-steel and the aperture is formed in a plate of-material of low expansion coefficient which is either welded to one end of the member (Fig. 10, not shown) or extends across a large aperture in the member (Fig. 9, not shown). In further arrangements the resilient member is either connected to or integral with the stud; the co-operating aperture may be formed in a U-shaped strip secured to the glass wall (Fig. 5, not shown) or in the glass wall itself (Fig. 6, not shown) and in the latter case the aperture may be lined with metal (Fig. 7, not shown).
