Title: Improvements in or relating to methods of manufacturing perforated shear plates for dry-shaving apparatus
IPC: B26B19/38
Filed: 1958-11-04
Abstract: 845,832. Dry shavers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 4, 1958 [Nov. 7, 1957], No. 35373/58. Class 131 [Also in Groups XVI and XXXVI] A perforated shear plate of foil for a dry shaver is produced by etching apertures in a thin metal sheet 1 by a chemical or electro-chemical process, so as to produce apertures 10 surrounded by rims 12 which project from the inner surface of the plate which is contacted by the cutting member. Apertures in a resist 2 on the outer side are in groups, and resist 6 on the inner side forms a pattern of islands each corresponding to such a group. Etching is carried out until less than half the thickness of metal has been removed, then stopped, and resist applied over all the inner side including the etched depressions, then etching is re-started so as to etch holes through from the outer side, and continued until each group of apertures merges into a single hole 10 surrounded on the inner side by a crenate rim 12.

Abstract: 868,699. Rectifying. UDYLITE RESEARCH CORPORATION. Nov. 4, 1958 [Feb. 3, 1958], No. 35444/58. Class 38 (2). In a rectifying arrangement for supplying large currents, e.g. for electrolysis or anodizing, the sharing of current between rectifiers acting in parallel is equalized by supplying each of the parallel rectifiers from a separate secondary winding on the same core leg of the supply transformer, the ends of these windings not connected to the rectifiers being connected together. Each leg 14 of a three-phase transformer carries a primary winding and two oppositely wound pairs of secondary windings 34, 74; 36, 37, each having one end connected through a rectifier 60, 94, 65, 98 to positive bus 62, and the other end connected to negative bus 56 which forms their star point. The arrangement thus forms two paralleled threephase bridge rectifying arrangements. Single phase and other polyphase systems are referred to.

Filed: 1974-08-14
Abstract: 1468864 Staplers SIGNODE CORP 14 Aug 1974 [15 Aug 1973] 35787/74 Heading B4C A stapler has a magazine 30 pivotally mounted on the handle portion thereof by a cam pivot arrangement 38 and held by a latching means 40 at its front end such that sideways pressure exerted on the magazine by the attempted insertion of a deformed staple causes rearward and downward movement of the magazine to a release position as the force of the latch 40 is overcome. The cam pivot 38 has two pivot pins 70, 72 which normally are located in a straight portion of slot 74 (as shown). Rearward movement of the magazine by said pressure allows pin 70 to move into a widened portion of the slot and hence allows rotation. The latch means 40 engages pins 42 at the other end of the magazine and is spring urged to a retaining position.

Abstract: 411,560. Making electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Illingworth, G.; 1889, Windermere Avenue, East Cleveland, Ohio, U.S.A.) Dec. 19, 1932, No. 36004. Convention date, Dec. 19, 1931. [Class 39 (ii).] In apparatus for exhausting or gas-filling electric incandescent lamps and similar devices, comprising a movable carrier with a series of heads each adapted to receive and carry one of the devices, a turret mounted adjacent to the movable carrier is provided with means for engaging the carrier heads to cause the turret to rotate to bring a work receiver or holder thereon into alignment with a carrier head, the turret holders being arranged to take, in turn, one of the lamps and part it from its carrier head as the exhaustion or gas filling is completed, means being provided for completing the sealing-off operation as the article is being indexed around the turret. The carrier heads 55, Figs. 1 and 3, are indexed intermittently in an anti-clockwise direction, and on approaching the turret, the lamp bulbs in the heads 55 pass through positions A, B, and C where preheating fires, consisting of burners 13 at the ends of yoked arms 14, heat a contraction 10 in the exhaust tube 11 of the bulb 12, the gas supply pipes 15 being mounted on a bracket 16 extending from a stationary shaft 17. This shaft also carries a lateral bracket 62 provided with downwardly extending arms carrying spaced bottom plates 65, 66 forming a channel within which a plate 58 slides between rollers 63, a headed shaft 22 being attached to the underside of plate 58 to carry the turret 20. A star-wheel 54 mounted loosely on the shaft 22, between the head of the latter and the turret 20, is coupled to the turret by a pin 55' and pressed upwardly by a helical spring 56. while the plate 58 carrying these members is pulled within its channel by a tensioned spring 59 in such manner that the teeth of the star wheel are located in the path of the work heads 55. After preheating, the lamp bulb passes to position D which is also occupied by one of the four heads of the sealing-off turret. These heads each carry oppositely disposed burners 23, 24 which, at position D, seal off the tube after the exhausting or gas filling is completed. The head is then dropped by the lowering of a shaft 28 carrying a block 27, in which the fuel supply pipe 26 is mounted, whereupon a movable jaw 42 co-operating with a fixed jaw 41 is actuated to grip the neck of the bulb below the fused glass. The head drops until a block 49 secured on pipe 26 strikes an arm 29<1>, and the bulb 12 strikes an adjustable rest 50 in a bracket 41. At position E the fires cut the thin string of glass usually connecting the bulb and exhaust tube and partially shape the seal, the shaping being completed at position F. The lamp is released at position G by a cam surface 69 raising the shaft 28 and producing automatically the opening of the grippers, whereupon a spring 67 brushes the bulb into a shoot 68.

Example (6) describes the preparation of a resin by heating a mixture of glycidyl 2, 3-epoxybutyrate and 2, 21-bis(4-hydroxyphenyl) propane to 120 DEG C. for 19 hours then raising the temperature to 160 DEG C. for an additional 6 hours.ALSO:The invention comprises a diepoxide of the general formula:  <FORM:0872977/IV (b)/1> wherein each R is a hydrogen atom or a hydrocarbon group and one R is always a hydrocarbon group; and wherein A is an epoxyalkyl, epoxycycloalkyl or epoxycycloalkylsubstituted alkyl radical, the epoxy group of which is at least one carbon atom removed from the ester group.  An a ,b -olefinic acid ester, in which the alcohol residue contains ethylenic unsaturation at least one carbon atom removed from the ester group, and the a  and b  carbon atoms of the acid residue are satisfied by at least one hydrocarbon group, is epoxidised by contacting with more than one mol of peracetic acid per mole of ester for a period of time sufficient to introduce oxirane oxygen at the sites of both carbon to carbon double bonds.  The epoxidation may be conducted at temperatures in the range of 0 DEG  to 100 DEG C. and the peracetic acid may be employed as a solution of 10 to 50% by weight in an inert medium such as ethyl acetate or acetone in the presence of a poly merization inhibitor.  The glycidic esters may be used as intermediates, or as stabilizers for chlorinated rubber and may be polymerized with other monomers such as 2,21-bis(4-hydroxyphenyl) propane to produce hard, solid resins.  Examples also describe the preparation of alkyl a -ethyl-b -propylacrylate by heating together allyl alcohol and a -ethyl-b -propylacrylic acid under reflux, and the preparation of 6-methyl-3-cyclohexylmethyl a -ethyl-b -propylacrylate from ethyl a -ethyl-b -propylacrylate and 6-methyl-3-cyclohexenylmethanol.
