Title: Interlock Structure for Two Manually Operable Toggle Switches.
IPC: H01H23/00
Filed: 1968-03-12
Abstract: 1,174,364. Interlocked switches. SQUARE D. CO. 12 March, 1968 [20 June, 1967], No. 11931/68. Heading H1N. A pair of identical toggle switches 12, 14, e.g. as in Specification 1,131,785, each have an operating handle 22 pivotable about an axis 66 between a switch open position, shown by switch 14 in Fig. 2, and a switch closed position, shown by switch 12 in Fig. 2, and a pin 56 extending from the handle and engaging in a notch 92 in an interlock member 80 or 81 rotatable about a pin 82. When switch 12 is actuated (its handle is moved [from the Fig. 1] to the Fig. 2 position), its pin 56 rotates member 80 anticlockwise so that a curved surface 86 on member 80 engages a linear surface 88 on member 81 to prevent clockwise rotation of member 81 and thus actuation of switch 14. Members 80, 81 are mounted on a plate 62 provided with openings 72 aligned with openings (50, Fig. 1) in the switches and threaded openings in ears 74 in an outlet box 16, these openings receiving screws 76 to position plate 62 and the switches on the box 16. Plate 62 also has openings 64 aligned with threaded openings 54 in the switches and openings in a cover-plate ( 18, Fig. 3) for the reception of screws 70. If when one of the switches, e.g. 12, is " on " it is subjected to excess current, a melting alloy overload unit (36, Fig. 3) allows the switch contacts to open, the switch handle remaining " on ". Subsequent manual operation of the handle from " on " towards " off " causes the handle to snap to a " tripped " position between the dead-centre and the " off " position. The switch is reset by moving the handle from the " tripped " to the off " position. The interlock members 80, 81 prevent actuation of one of the switches when the other switch is in a " tripped " position.

Abstract: 714,209. Toothed gearing. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. May 15,1952 [May 16, 1951], No. 12317/52. Class 80 (1) [Also in Group XVI] An anti-backlash gear drive for the impression cylinder of a printing press comprises a toothed driving rim having inserted therein a toothed segment movable in a circumferential or radial direction in relation to the toothed rim and which prevents backlash between the rim and the driving gear at the moment of lifting and lowering of the impression cylinder. In the form of Fig. 1, the toothed segment 6 is mounted on an annular boss 7 and is received in a recess 5 having a width considerably less than the width of the rim 1. A spring 8 urges the teeth of the segment against the coacting teeth of the driving wheel and prevents relative displacement of the rim 1. A pin 9 serves as a stop for segment 6. In the form of Fig. 2, the segment 10 is formed with a part annular guide 11 one end of which is carried on a sleeve 13 eccentrically mounted on a screw and the other end of which is urged by a spring 14 radially outward, a screw 17 serving as a stop. The spring forces the teeth of the segment into deeper engagement with the teeth of the driving gear and again prevents relative displacement. The eccentric sleeve 13 is rotated to effect adjustment of the teeth of the rim. In another similar form the annular guide 11 is slidably mounted in an annular slot in the face of the rim 1 and is urged tangentially by a spring acting against one end. The other end abuts an eccentrically mounted sleeve whereby adjustment can be made to the circumferential position of the segment. The pitch module of the teeth of the movable segment may be somewhat smaller than that of the driving wheel so that tooth clearance between these parts is small and accurate tooth engagement is ensured.

Title: Process for the production of polymeric materials
Inventor: BURNETT JAMES DONALD
IPC: C08F291/18
Filed: 1958-04-18
Abstract: Segmented polymers, i.e. graft and block copolymers and branched chain homopolymers, are produced by a process in which a normally solid thermoplastic high polymer is masticated in an oxygen-containing atmosphere at a temperature below 170 DEG C. whereby peroxy groups are formed in the polymer and is subsequently subjected to conditions causing the decomposition of peroxy groups in the presence of a monomeric compound containing one or more olefinic double bonds and capable of polymerization under the influence of free radicals, this step being carried out in the absence of a concentration of oxygen which would otherwise inhibit the polymerization.  Preformed polymers specified are polythene, polypropylene, polyisobutylene, polystyrene, polyvinyl alcohol, polyvinyl acetate, polyvinyl and polyvinylidene chlorides, polytrifluorochloroethylene, polytetrafluoroethylene, polymethyl and polybutyl acrylates, polyacrylonitrile, polyvinyl pyridines, poly-N-vinyl pyrrolidone, polybutadiene, polyisoprene, polychloroprene, interpolymers of butadiene with styrene, acrylonitrile and methyl methacrylate, polyethylene glycols, polyesters, polyamides, polyurethanes, polyureas, polysulphonamides, polysiloxanes, natural rubber, cyclised rubber, rubber hydrochloride, chlorinated rubber, gutta percha, and cellulose esters, ethers and acetals.  Monomeric compounds specified are acrylic and methacrylic acids and their methyl, ethyl and n-butyl esters, 2-ethoxyethyl and 2-chloroethyl methacrylates, ethylene dimethacrylate, acrylonitrile, methacrylonitrile, acrylamide, n-butyl acrylamide vinyl and vinylidene chlorides, methyl vinyl and methyl isopropenyl ketones, styrene, vinyl toluenes, vinyl toluene sulphonic acids, divinyl benzene, acenaphthalene, vinyl acetate, vinyl pyridines, vinyl carbazole, N-vinyl pyrrolidone, butadiene, isoprene and chloroprene. Polymerization may be induced by the action of heat, ultra-violet light or reducing agents which are preferably used in an aqueous phase in which the monomeric compound is dispersed or dissolved, suitable agents of this type being sulphites, bisulphites, phenyl sulphinic acid, phenylhydrazine, thio-beta-naphthol which may be used in conjunction with iron salts and sodium pyrophosphate, fructose in the presence of ferrous ions and polyamines.  The examples describe the polymerization of methyl methacrylate in the presence of peroxidised polythene and polypropylene, and styrene in the presence of peroxidised polythene.  In an Example (7) it is stated that the products formed by polymerizing styrene with peroxidised polythene may be given ion-exchange properties by sulphonation with sulphuryl chloride.  Specification 857,798 is referred to.
