Title: Improvements in varying speed sheet delivery mechanism for printing machines
IPC: B41F13/00
Filed: 1928-12-21
Abstract: 326,838. Linotype & Machinery, Ltd., Dowson, R., and Taylor, H. B. Dec. 21, 1928. Delivery apparatus. -In sheet-delivering mechanism for rotary machines of the type in which the sheet is taken from the impression-cylinder by chaincarried grippers, the chains are driven at the normal speed during the take-off of the sheets, this normal speed being slightly less than the peripheral speed of the impression-cylinder so that the danger of dragging the sheet and so smudging the impression is obviated. The speed of the chains is decreased to enable the sheet to be deposited, and is then increased to normal again. As shown, the impression-cylinder shaft carries an elliptical gear-wheel 7 meshing with a corresponding gearwheel 8 rotatable, with a concentric gear-wheel 9, on a fixed shaft 10. The wheel 9 drives, through differential gearing 11, 12, 16, 18, a gearwheel 19 on the shaft of the sprocket wheel 5 of the gripper-chains 3. The shafts 13, 17, on which the wheels 11 and 12, and 16 respectively are mounted, are carried by an arm 14 pivoted on the shaft 10 and under the control of a cam 15 on the impression-cylinder shaft.

Title: Improvements in or relating to the manufacture of electrical contacts
Inventor: TALBOT RALPH ERNEST CLAUDE
IPC: H01H1/02
Filed: 1960-11-03
Abstract: 915,541. Making electric contacts. ENGELHARD INDUSTRIES Ltd. Nov. 1, 1961 [Nov. 3, 1960], No. 37865/60. Class 83 (2). In making a bimetallic electrical contact a wire of noble metal or an alloy thereof is joined in end to end relation with a wire of base metal or an alloy thereof, a length of wire including the join is cut off and the composite slug so obtained is then deformed to produce the contact having a contact face of noble metal or alloy thereof. The end of a pure copper wire is electric resistance welded to the end of a pure silver wire so that no upset occurs at the join, a piece of the wire is cut off to form a slug as shown in Fig. 3 comprising silver 2B, 0.135 inch long, and copper 1B, 0.390 inch long, which is then deformed in a press at room temperature to form the rivet contact shown in Fig. 4. The deformation may take place at elevated temperature and the shank may be hollow. The rivet may be formed by extrusion. Specification 815,136 is referred to.

Abstract: 885,191. Carrying cables through partitions. VEROLME UNITED SHIPYARDS N.V. Nov. 9, 1959, No. 37917/59. Class 36. Cables 10K, 11K are carried through a bulkhead in a water-tight and gas-tight fashion by means of a device comprising a pot 1 the bottom 2 of which has an ample aperture 4 for the cables and the cover 3 being likewise apertured 5. Within the pot adjacent the bottom and the cover are sealing plates 6 and 7 of incombustible, heat-insulating material, apertured to fit the cables closely and dimensioned to fit closely within the pot. These plates are preferably in two halves for ease of assembly and, together with pliable, non-hardening, heatinsulating, flame-quenching and resilient sealing compound 8 they seal the cables within the pot. The plates 6 and 7 and the cover 3 are all free to slide axially along the cables so that the assembly is self-adjusting to changes in external or internal pressure due to e.g. flooding on one side of the bulkhead or partial loss of compound by fire. A suitable compound consists of petroleum jelly, fatty acids, and Paris White. The sealing plates may be of asbestos cement.

Title: Cigarette lighter heating coils
IPC: F23Q7/00
Filed: 1957-12-10
Abstract: 831,699. Making cigarette-lighter heating elements; resistance welding. CASCO PRODUCTS CORPORATION. Dec. 10, 1957 [Dec. 24, 1956], No. 38382/57. Classes 83 (2) and 83 (4). [Also in Groups XI and XXXVI] In a method of making a heating coil for a cigarette lighter a spiral coil, wound from-resistance wire or ribbon, the oxide of which is electrically insulating, is heated to form a coating of insulating oxide, the outer end portion of the spiral then being deformed to fracture the oxide and expose the underlying metal for electrical engagement with another metallic part. A cigarette lighter heating element comprises a retainer cup 10 to which is welded a spiral heating coil 11, Fig. 1, of an aluminium-iron-nickel alloy which has previously been heated to provide an insulating oxide coating. In order to expose the metal for welding, the end 22 of the coated coil is flexed, stretched or corrugated as at 24, which deformation cracks and removes the oxide coating. The internal welding electrode initially contacts the crests 25 of the corrugations resulting in high current density and high resistance which produces rapid heating; as the electrodes move together during welding the corrugations are flattened and the relative movement between the ribbon and the cup 10 results in a wiping action which improves electrical contact. The internal end 19 of the heating coil is cleaned by abrasion on insertion into the head 15 of a stud which passes through the retainer cup 10 and is insulated from it. A ceramic block 13, Fig. 2 (not shown), forming a portion of the igniter plug, is attached to the cup by the stud.

Abstract: 384,622. Packing matches. LœCK, W., 144, Obere Birkenwaldstrasse, Stuttgart, Germany. Aug. 30, 1932, No. 24218. Convention date, Jan. 28. [Class 94 (i).] The machine forms match packets of the kind in which matches are housed in the corrugations of a corrugated strip of paper attached to a cover strip. A strip a of paper is fed between fluted rolls 8, 9, Fig. 2, and is corrugated into the form shown in Fig. 3, adhesive being applied to the ridges a<1> by a roller 12. A smooth roller 10 feeds a strip b of paper, &c., and a strip c of tear-off matches so that the stalks c<1> lie within the compartments which are formed by the union of the sheets a, b by adhesive. A toothed wheel 11, rotating with the wheel 10, projects between the stalks and positions them correctly with respect to the strip a. The arrangement is now as shown on the left in Fig. 6, with the heads d of the matches projecting beyond the sheets a, b. After leaving the rolls 9, 10, the composite strip travels between guide rolls to allow the adhesive to dry. The strip c is then transversely severed at g and the sections are pulled by grippers into the position shown in the centre in Fig. 6, with the heads inside the corrugations. The stalks are separated by cutting along the line y-y. The strip may now be transversely cut into sections of the desired length. Frictional igniting composition may have been applied to the strips a, b along the line of the edge of the strip a remote from the heads d.
