Inventor: COSCIA ANTHONY THOMAS
IPC: D21H19/50
Filed: 1967-05-10
Abstract: 1,186,933. Coated materials. AMERICAN CYANAMID CO. 10 May, 1967, No. 21811/ 67. Headings B2E and B2K. [Also in Divisions C2 and C4] An aqueous coating composition comprises a water-soluble film-forming protein, e.g. casein, gelatin or soya protein, a protein-insolubilising agent which is a methylamine-epichlorhydrin adduct of the formula I:- wherein n is from 1 to 9, and optionally a pigment, e.g. papermaker's clay, titanium dioxide, calcium carbonate, phthalocyanine blue, ultramarine blue or carbon black. The protein and the insolubilising agent may be partially reacted together before use, e.g. by heating at 50 to 60‹C. The coating may be cured by heating to 190 to 300‹F. Specified substrates are paper, films, aluminium foil, paper-board, plaster-board, wood particle board, wood or mineral fibre ceiling tile board, glass, pigmented polyethylene and oxidised polypropylene.

Title: Bogie-vehicle steering mechanism
IPC: C22B19/18
Filed: 1935-08-01
Abstract: 454,399. Steering road vehicles. JONKHOFF, H. W., 4, Berger (Rhein) Ufer, D³sseldorf, Germany. Aug. 1, 1935, No. 21849. Convention date, Feb. 11. [Classes 79 (ii) and 79 (v)] A vehicle with steering bogies comprises a cross-beam 2, Figs. 1 and 3, carried by the vehicle body, a pair of bogie frames 1 pivoted at 4 to the ends of the beam, front and rear wheels on each bogie frame, at least either both front or both rear wheels being steerable, and a rod 8 mounted between each pair of steering wheels to keep them parallel in all steering and bogie positions. In the construction shown in Figs. 1 and 3 applied to a hand truck, the wheels are mounted on arms 6, 7 independently pivoted at 5 to the bogie frames 1 and controlled by springs 18. When the body of the truck is swung round as shown in Fig. 3 the bogies 1 are slued relatively to the body but the steering wheels keep parallel to the body sides. In the construction shown in Figs. 4 and 6 applied to a trailer, each bogie frame comprises a pivoted arm 9 and a spring 18a and is mounted on four wheels. The front or steering wheels are mounted on superposed forked levers 11a pivoted on horizontal pins 11 carried by a vertical pin 10 rotatably mounted in the arm 9. Thus the steering wheels can be steered about the pins 10 and can also rock about the horizontal pins 11. Steering arms 13 are sleeved at 12 on the pins 10 and are connected together by a rod 14 so that the two sets of steering wheels always remain parallel to each other and to the longitudinal axis of the vehicle body. In the construction shown in Fig. 9 applied to a three-axled motor vehicle the road wheels of the bogie frames 1 are mounted, as in Figs. 1 and 3, on arms 6, 7 but the steerable wheels of the bogies are mounted on a shaft 8 mounted in universal bearings 15 in the arms 6. Thus the steerable bogie wheels are always kept parallel to each other by the shaft 8, although the latter is not always parallel to the cross-beam 2 The steerable wheels are driven from a propeller shaft 7 through differential gear 17. The angle of rotation of the bogies 1 relatively to the cross-beam 2 is increased if the bogie pivots 4 are nearer the centre line of the vehicle than are the universal joints or bearings 15.

Title: Improvements in mechanism for feeding sheets to wrapping machines and the like
IPC: B65B41/10
Filed: 1936-08-17
Abstract: 471,139. Feeding sheets ; registering webs. PACKAGE MACHINERY CO. Aug. 17, 1936, No. 22647. Convention date, Oct. 1, 1935. [Class 100 (i)] A machine for feeding sheets from a pile, or sheets cut from a web, to wrapping or like machines is described in connection with a wrapping - machine as set forth in Specification 471,138, [Group XVII], in which sheets cut from a web by means of a stationary cutter 118 and a rotary cutter 119 are finally wrapped round a parcel a after receiving gum from rollers 165 by means of folding mechanism as described in Specification 471,138. The web is fed from a roll 105 over a tensioning roller and prior to the cutting operation is corrugated by alternating wires 109, 110 lying between cork rolls 111 geared to and resting on a steel roller 112 driven by change-gears and a sprocket mechanism from a shaft 37 which operates the wrapping mechanism. The rigidity of the paper is thus increased as it passes through the cutting mechanism. Guiding fins 122 on the shaft of the cutter act to strip the paper from the cutter. The paper is also maintained taut for this cutting operation by engaging with the feed device which feeds the severed sheet to the wrapping-machine at a speed greater than that of the web. This mechanism comprises a pair of adjustable feed belts 125 which pass over pulleys 126, 127, 128, 129 one set of which are mounted on a fixed bar and the other on a bar which is adjustable laterally for dealing with sheets of different widths. The bars are fitted with plates 131 arranged between the adjacent runs of the belts. The belts are driven from the cutting rollers at a speed greater than that of the feed rollers, the pulley 126 of the adjustable belt being splined to its driving shaft. The paper is pressed against the lower feed belts by means of rollers 140 which are mounted in spring- pressed arms carried by fixed frames 135 supported on bars 138, 139, the frames 135 being formed at their forward ends with toothed portions 146, but not with rollers 140. Within the frames 135 are mounted frames 150 which are carried by a parallel linkage system 151, 152 secured to shafts 138, 139. Rollers 152 similar to the rollers 140 are carried by the frames 150. The shaft 138 is oscillated by an adjustable cam on the shaft 115, and by this means the frames 150 are lowered after the sheets have ceased being fed by the belts 125 and rollers 140, and the sheets thus are moved on to the racks 146 and pass gently to adjustable stops 160 which register the sheets for the wrapping operation. Additional racks similar to 146 may be arranged outside the racks 146 to assist in guiding wide sheets into operative position. Specifications 394,192 also is referred to.
