Abstract: 1,230,038. Corrugating; making switches. 13 Nov., 1969 [24 April, 1969], No. 55672/69. Headings B3A and B3E. A method for the manufacture of a zig-zag folded metal contact strip for a fixed contact of an electric switch is characterised in that the strip is alternately bent in one direction and then in the other direction out of its flat surface over a movable tooth which, during the bending operation, is held stationary. A machine for carrying out the method comprises a housing 5 provided with opposing sets of movable vertical teeth 6<SP>1</SP>, 6<SP>11</SP> having projections 10<SP>1</SP>, 10<SP>11</SP> for sliding horizontally in guiding grooves 11<SP>1</SP>, 12<SP>1</SP>, 11<SP>11</SP>, 12<SP>11</SP> in the housing. The teeth are moved horizontally for a distance equal to the thickness of a tooth by forks 14<SP>1</SP>, 14<SP>11</SP>. The teeth releasably engage in slides 15<SP>1</SP>, 15<SP>11</SP> and 17<SP>1</SP>, 17<SP>11</SP> vertically reciprocable in guides in the housing. Pushing members 16<SP>1</SP>, 16<SP>11</SP> engage and disengage the teeth with the slides 15<SP>1</SP>, 15<SP>11</SP> and 17<SP>1</SP>, 17<SP>11</SP>. Preceding the teeth is a vertically reciprocable block 18 with guiding rollers 19 which receive the strip 13 to be folded and as the block reciprocates the strip is first bent over the edge 811 of the tooth 6<SP>11</SP> and then over the edge 8<SP>1</SP> of the tooth 6<SP>1</SP>. After this the slides 15<SP>1</SP>, 15<SP>11</SP> are removed from the teeth by the members 16<SP>1</SP>, 16<SP>11</SP> and the teeth hang temporarily in the grooves 12<SP>1</SP>, 12<SP>11</SP>. Thereafter the empty slides 15<SP>1</SP>, 15<SP>11</SP> are returned to the starting position whereafter the forks 14<SP>1</SP>, 14<SP>11</SP> move the sets of teeth the distance of one tooth thickness into the slides 15<SP>1</SP>, 15<SP>11</SP> and the machine is restored to its starting position. The teeth 6<SP>1</SP> have a transverse groove 20 in their flank 9<SP>1</SP> for co-operating with a pivoted angular tool 22 for forming tubular portions at alternate bends in the strip. Finally the folds are pressed closely together as they leave the teeth by a horizontally reciprocated pawl-shaped member 26 and the bent strip is discharged from the machine through a shoot 27. The driving means for the moving parts are mechanical, hydraulic or pneumatic.

[Also in Division G4] In order to measure the diameter of a frustoconical workpiece not shown, a disc 20 is resiliently pressed against the workpiece so that as the workpiece is rotated about a vertical axis the disc is also rotated to cause a photo-electric incremental encoder 28 to produce a corresponding number of pulses. Vertical movement of the entire measuring unit is converted into a corresponding number of pulses by an inductive incremental encoder 45, and a feeler 25 is provided so that the height of the unit can be checked manually. Means 30, 13, 18 are provided in order to adjust the direction of the axis of the disc 20 so that the disc bears normally on the surface of the workpiece and a linkage 40, 42, 44, 54 effects a compensating movement within the height encoder 52.

Abstract: 1,232,583. Weldable coatings. J. P. BRENNAN. 21 May, 1968 [23 May, 1967], No. 24014/67. Heading B2E. A normally non-weldable synthetic plastics material is rendered weldable by applying thereto a foamed aqueous emulsion containing a thermoplastic polymer and drying or allowing the emulsion to dry to deposit the thermoplastic polymer on the synthetic plastics material. The normally non-weldable synthetic plastics material may be a foamed plastics material such as polyether urethane or polyester urethane foam. The aqueous emulsion of the thermoplastic polymer may be foamed by adding a surfactant and whipping air into the emulsion by means of a high speed agitation or alternatively employing a continuous foaming device. The aqueous emulsion may comprise homopolymers or copolymers of acrylic acid and acrylic esters, e.g. polybutyl acrylate and butyl acrylate vinylisobutyl ether copolymer; self cross-linking acrylic resin emulsions; vinyl homo- or co-polymers; or mixtures thereof. The aqueous emulsion may be admixed with a thickener such as vinyl pyrrolidone copolymer or methyl cellulose whereby the viscosity of the emulsion is controlled. For the purpose of achieving low frequency welding properties the aqueous thermoplastic polymer is admixed with up to 10% by wt. of ethylene/vinyl acetate copolymer or polyethylene in powder form. The foamed aqueous emulsion is applied to the normally non-weldable synthetic plastics material, heated to remove the water content and to cause the foam structure of the thermoplastic polymer to break down to produce a mesh like coating.

A generator producing an output voltage of a frequency proportional to the speed of a vehicle has some of its parts in common with a speedometer indicating vehicle speed. The apparatus includes a permanent magnet 25 and flux return member 24 mounted on a shaft 14 rotatable at a speed proportional to vehicle speed. The flux return member is either substantially rectangular, Fig. 2 (not shown), or discoidal with peripheral teeth, Fig. 7 (not shown), and acts as a variable reluctance rotor for a stator 70 comprising a coil 71 mounted on an axially magnetized P.M. 72 and enclosed by a ferromagnetic casing 77. The frequency of the coil output voltage is proportional to the speed of the member 24 and hence to vehicle speed. In a modification, Figs. 5 and 7 (both not shown), there is no ferromagnetic casing around the coil, the P.M. and coil are placed radially beyond the teeth on the flux return member 24 and a ferromagnetic rod (123) is spaced circumferentially from the output coil to act as a return path for the flux of the generator stator P.M. In both embodiments an eddy current drag cup 32 located adjacent the rotatable P.M. 25 carries a pointer 43 to indicate vehicle speed on a scale 44, Fig. 4 (not shown), the torque on the drag cup being balanced by a hair spring 46.

Abstract: 1,250,836. Folding stockings. A. STOSSL. 10 April, 1969 [11 April, 1968], No. 18515/69. Heading B8C. Stockings are folded by winding about the prongs 8 of a rotated fork to between which, when stationary in a vertical plane, the stockings are extended on a table 1 in a horizontal plane, across a table cut-out 5 through which the fork rotates. The table 1 is displaceable, about a vertical axis 2, from a position 1<SP>11</SP> where it is manually loaded with the stockings from a conveyer 3, to the winding position 1<SP>1</SP> wherein it is retained by a sprung pawl 4. To accommodate different widths of folded stockings, the prongs of the fork may be adjustably spaced apart, or the fork may be replaceably mounted on a shaft 9 whereby it is rotated by a motor 23, the drive whereof is initiated from a switch 24 and is controlled for a predetermined winding time and to halt the fork with the prongs in a horizontal plane for unloading of the folded stockings. During winding, the stockings are urged against the prongs 8 by a pair of vertically spaced jaws 10 which are resiliently loaded, to follow the changing spacing therebetween, by springs 17 acting about pivots 19 of the jaws 10 on arms 12 which are urged together by a spring 15 and are pivotally mounted to a sleeve 14. The jaws 10 are retracted from the prongs 8, to permit removal of the folded stockings, via a lever mechanism 20 actuated by a foot pedal 21, the jaws 10 optionally being spaced apart from the stockings in the horizontal position of the prongs 8 by cam projections provided on the shaft 9 at the junction thereof with the prongs 8. The prongs are returned to their vertical alignment, permitting displacement of the table 1, by a rotating shaft 9 via a ratchet 26 operated from a foot pedal 28. The wound stockings may be laid between two layers of plastics foil drawn from a reel 30 by a roller 29, the drive whereof is photo-electrically initiated when the stockings are placed thereon and wherefrom a conveyer 31 leads to a package welding device. Alternatively, the stockings may be removed from the prongs 8 within a bag, an open end whereof is pulled over the jaws 10 before they are retracted, the open end of the bag subsequently being closed by welding or pasting.
