Abstract: 612,445. Catamenial appliances. SYKES,W. May 20, 1946, Nos. 15141/46 and 11236/47. [Class 81(ii)] [Also in Group VIII] An apparatus for the manufacture of sanitary towels comprises two sets 26, 27 of rollers through which a strip 48 of absorbent material passes, the set 26 being intermittently, and the set 27 continuously, driven so that the strip is torn into pads 48a of predetermined length, the pads being fed to the orifice of a tubular carrier 47 for towel-casing material 52 and being drawn therethrough encased in the introverted material. Power is supplied by a motor 12, mounted on a hinged platform 23 for adjustment purposes, through belt or chain, and gear drive to a shaft 21, 37, the rollers 27 being driven by gears 32, 33 and the rollers 26 by gears 30, 31 through gears 34, 35. Gear 30 has interrupted teeth to provide for the intermittent action of the rollers 26. The casing material 52 with the enclosed pads 52a is drawn through carrier 47 by rollers 39 geared to the shaft 37 and may be cut manually into towels or by a device driven from shaft 37. This device' which may comprise a pivoted or rotary blade and a stationary knife may be electrically controlled. The carrier 47 is supported by a clamp 46 pivoted at 45 so that the carrier may be swung laterally for reloading with casing material. In a modification, shorter carriers, say four, are formed at their delivery ends with flanges adapted to be fixed frictionally in holders pivoted on a head rotatable on a horizontal shaft, the arrangement being such that on rotation of the head, the other ends of the carriers are presented successively opposite the feed chute 51, one or more of the carriers not so presented being available for reloading. The head may be rotated manually, or by manual operation of a clutch connecting shaft 37 with a Maltese-cross mechanism. Alternatively, the control may be automatic.

Title: A method and means for controlling the supply of electric current to individual consumers
IPC: H01H71/74
Filed: 1941-11-25
Abstract: 553,183. Switching systems for consumption apparatus. MELLONIE, S. R. Nov. 25, 1941, No. 15168. [Class 38 (iv)l [Also in Group XXXVII] Current supplied to consumers is controlled by providing the consumers with circuit-breakers which cut off the circuit or a part of it when a maximum current is exceeded, the " maximum being varied in a cyclical manner by current supplied over the lines. In the form shown, the total current to the consumer passes through an electromagnet 4 which attracts an armature 5b which releases a contact member 6 so that this moves away from a contact 7. Resetting is effected by counterclockwise rotation by hand of a pin 14. The initial position of the armature and therefore the current at which the device operates is regulated by a cam 10, which rotates once in twenty-four hours, and is driven by a synchronous motor. In a modification, Fig. 2 (not shown), a single electromagnet controls two armatures which release two switch arms. Resetting is effected by manual rotation of a cam which is rotated one way to engage one switch arm and the other way to engage the other. Both switch arms cannot therefore be held closed simultaneously. The circuit-bracket instead of cutting off the whole circuit may cut-off only the "non-essential " part of it.

Abstract: 562,552. Lubricating grease compositions. STANDARD OIL DEVELOPMENT CO. Oct. 29, 1942, No. 15179. Convention date, Sept. 12, 1941. [Class 91] An' anhydrous, water-insoluble, temperature stable and reversible grease comprises a mixture of mineral lubricating oil, aluminium soap and a non-basic barium soap. The proportion of the total soap in the finished compositions ranges from 5 to 40 per cent by weight, and the ratio of the barium soap to the aluminium soap varies between 1 to 1 and 10 to 1 and preferably 5 to 1. The mineral lubricating oil is generally a base oil of viscosity 50 to 220 at 210 F. S.S.U., and preferably of viscosity 100 to 2400 at 100 F. S.S.U. The soaps may be prepared from the usual fats or fatty acids including fatty acids split from hydrogenated fish oils which contain at least 9 carbon atoms to the molecule. The barium soaps are preferably made by using a more active hydrated barium oxide obtained by reacting barium oxide and water in an inert atmosphere, such as in the presence of a mineral lubricating oil, a smooth emulsion of hydrated barium oxide in oil being obtained. The soaps may be prepared separately before compounding, or in the case of the barium soap, the fat or fatty acid may be mixed with the mineral oil and then saponified, the hydrated barium oxide being in stoichiometrical or slightly less proportions. The compositions may contain other additives, such as anti-oxidants.

The discs may have orthogonal projecting lugs sliding one over the other to provide a shunting flux path (Figs. 2a, 2b, not shown). A ring magnet 6 having end polepieces 7 (Figs. 3, 4) may be surrounded by annular magnetically soft discs 2 having studs 8 engaging inclined grooves of a split ring 9 of high thermal expansivity anchored at one end to the polepieces, so that the disc separation is varied with temperature to compensate flux variations. Two radially magnetized rings co-operating with a yoke (Figs. 5, 6, not shown) may have opposed hollow central polepieces containing elements of high thermal expansivity adjusting the spacing of conical spring steel discs from the magnetic rings, to compensate variations of gap flux. A focusing magnet (Figs. 7, 8) comprises an inner tube surrounded by ring magnets 6 and surrounding magnetically soft spaced discs 2, interconnected by a magnetically soft bar 16 terminating in an end member attached to a compensating pair of diametrically opposed bars 17 of high thermal expansivity; which expand and contract with temperature change, shifting the discs towards and away from the centres of the magnet rings, whereby changes of magnetic flux in the inner tube is compensated for temperature change. In a modification (Figs. 9, 10, not shown) magnetically soft rings surround each magnet circumferentially and fully or partly overlie adjacent polepieces whereby a portion of the flux is shunted. Diametrically opposed bars of highly thermal expansive material are arranged to traverse the rings with temperature changes over the magnets and polepieces to compensate the flux in the inner tube. The magnets may be ferrite.

Abstract: 905,495. Drawing wire. COPPERWELD STEEL CO. May 5, 1960 [June 12, 1959], No. 15913/60. Class 83 (4). An apparatus for drawing clad wire and rod dry, particularly aluminium clad steel, comprises a capstan 14, a die assembly 12 and a rotating wiper 45 which applies a carrier such as castor oil to provide some surface tackiness on the wire. The die assembly is pivotally supported between brackets 16a and comprises an open top soap box, the front wall of which supports the dies. The wire travels in the direction of the arrows 35 and passes first through an entrance die 36, an intermediate die 37 and a drawing die 38. The dies 36 and 37 have bearing diameters 48 and 50 respectively which are each slightly larger than the outside diameter of the wire passing through them and the final cross-section is controlled by the die 38. In operation, the wire is dabbed with the carrier, picks up lubricant as it passes through the box and carries it into the dies 36 and 37. There is a considerable pressure build-up in the space between the bearing 48 and the passage 51 and a still greater pressure occurs between the bearing 50 and the passage 53 so that the aluminium cladding is drawn in this region. The die 38 is of tungsten carbide, the drawing speed is up to 400 feet per minute and the proportion of cladding is about 20% of the total cross-sectional area. The taper angle of the passages 52 and 53 is 12 to 16 degrees and the radial clearances in the dies 36 and 37 are preferably 0.0025 and 0.001 inch respectively.
