Inventor: LIGHTFOOT WILLIAM ERNEST
IPC: B65B61/22
Filed: 1952-10-15
Abstract: 736,979. Packaging. MARTIN & MARTIN, Ltd. Dec. 23, 1953 [Oct. 15, 1952], No. 25866/52. Class 94 (1). A machine for inserting cotton wool plugs in the necks of filled bottles or jars comprises a pair of rollers 1, Fig. 1, to feed a rope 2 of cotton wool, a gripper 3 to separate pieces of wool from the rope, a carrier 5 for receiving the separated pieces of wool, means for moving the carrier 5 to a position over the mouth of a bottle 8 and a plunger 10, Fig. 2, for pressing the piece of wool through a slot in the carrier into the bottle. Preferably the insertion of the wool into the bottle is completed by second and third plungers 12, 13. The gripper 3 moves away from the rope of wool 2 along a rail 4 and the carrier 5 is moved over the mouth of the bottle 8 by an arm 6. The bottles may be mounted in trays having a central rib on which bottle clips are mounted, the trays being moved towards the machine on a conveyer belt and being fed through the machine by a sprocket 9 which engages the necks of the bottles.

Title: Improvements in electromagnetic vibratory devices
IPC: H03H9/48
Filed: 1935-09-18
Abstract: 462,983. Oscillating - machines. ASSOCIATED ELECTRIC LABORATORIES, Inc. Sept. 18, 1935, No. 25902. Convention date, Oct. 19, 1934. [Class 35] [Also in Group XL] A device to be supplied with current of several frequencies and give out current of a single frequency consists of a rod clamped at its ends and carrying two armatures co-operating with field coils, so that when one armature is activated by an alternating current in its field coil the rod vibrates with its natural frequency of torsional oscillation and the other armature yields current of this frequency. The armatures 15, 16 consist of flat plates in the same plane secured in slots in the ends of two pieces of rod 18, 19, and connected by a heavier rod 17. The two field coils are similar and each works in conjunction with a permanent magnet 1 and polepieces 2, 3. The coils are wound on spools made in two parts and recessed to accommodate the armatures. The rods 18, 19 are clamped to the ends 20, 21 of the frame 8 of the device by caps 22, 23 and screws 24, 25, the caps 22, 23 being each formed with two sharp edges 26, so as to grip the rods at definite points. In order to tune the apparatus the ends 20, 21 are adjustably secured to the frame 8 by screws 27, 32 passing through slots 28, 33.
Patent GB-534775-A (GB)
Title: Improvements in or relating to the treatment of artificial textile materials
IPC: D06M13/188
Filed: 1939-09-15
Abstract: 534,775. Artificial filaments &c. SOWTER, P. F. C., and PERRY, R. G. Sept. 15, 1939, No. 25929. [Class 2 (ii)] Artificial textile materials made of or containing an organic derivative of cellulose are subjected uniformly along their length and in the absence of tension sufficient to stretch them to the action of a homogeneous medium containing a latent solvent for the cellulose derivative in admixture with water or with water and an organic compound containing an alcoholic hydroxyl group. Artificial staple fibres, filaments, threads, yarns, fabrics, and ribbons may be treated. The treatment is carried out so as to produce an increase in extensibility or in the case of staple fibre to produce a crimped or crinkled product. The latent solvent may be methylene chloride, ethylene chloride, or ethyl acetate. The organic hydroxyl containing compound may be an aliphatic monohydric alcohol such as methyl or ethyl alcohol, or a polyhydric alcohol such as glycol or glycerol. Water may be present in addition to the organic hydroxyl compound. The proportion of water in the treating medium may be as much as 80-90 per cent. The treating medium may contain diluents such as benzine, petrol ether, toluene, or benzene. Solvents or softening agents may also be present. Preferably shrinking is allowed to take . place. The treatment results in an increase in extensibility. It may be applied to wet-spun materials which are of high tenacity or to materials which have been subjected to a high degree of stretching. The treatment may be applied to staple fibres in loose condition or in the form of a sliver or roving. The fibres become crimped or crinkled. Hygroscopic polyhydric alcohols or hygroscopic salts may be applied to the treated fibres for conditioning or de-electrifying purposes and for facilitating carding and spinning operations. Materials of cellulose acetate or other cellulose ester of ether may be treated. Suitable treating media are mixtures of water with 4-6 per cent. of ethyl acetate, water with 6-8 per cent. of ethyl acetate and 4-6 per cent. of ethyl alcohol, and a mixture of 60-90 per cent. of ethyl alcohol, 9-3 per cent. of ethyl acetate, and 31-7 per cent. of water. The treatment may be effected at raised or lowered temperatures. Specifications 380,504, 389,823 and 457,933 are referred to.

Title: Marking apparatus
IPC: B41F17/20
Filed: 1960-07-26
Abstract: 902,737. Printing machines. GOTTSCHO Inc., A. July 26, 1960 [Dec. 24, 1959], No. 25933/60. Class 100 (2). Printing is effected on the curved surfaces of articles A1, A2, A3, A4, &c. as they are moved along a horizontal path by a conveyer 16 beneath a swingable printing mechanism 10. The mechanism comprises a housing which is pivotally mounted on a fixed support 30, is spring urged into the path of the moving articles and carries contacting printing and inking rollers 64, 114. The printing roller is held against rotation by a latch mechanism 102, Fig. 4, until the roller housing is pushed upwardly by a contacting article whereupon due to relative displacement between a lever 158 of the mechanism which is pivoted at 160 to the fixed support 30 and a lever 150 of the same mechanism which is pivoted at 152 to the housing, the roller is freed to rotate by the disengagement of a nose 154 of the lever 150 and a notch 156 of a stop member 100 integral with the roller. Rotation of the type-carrying body 86, Fig. 6, of roller 64 is effected by bearer rims 94 which are rotated by contacting the articles and drive the body through slip clutches 96 when the stop member 100 is free of the latch mechanism. The inking roller is of the reservoir type and comprises cylindrical halves 122 and 130, Fig. 3, threadedly engaged through integral sleeves 116 and 126 such that the axial length of the roller may be adjusted thus allowing ink supply regulation to the annular inking pad 136 via an absorbent sleeve 140 carried by a rigid cylindrical sleeve 138. The mechanism 10 may be mounted to operate in a vertical plane as shown, or in a horizontal plane, the fixed support 30 being drilled with both vertical and horizontal bores 28, 32 for this purpose, the required mounting of the support being effected through the interengagement of a vertical rod 26 and the appropriate bore.

Abstract: <PICT:0895779/III/1> <PICT:0895779/III/2> An apparatus for mixing liquids to form emulsions or to polymerize or bring together reactants for polymerization comprises a cylinder into which the component materials are introduced under pressure (material of lower viscosity preferably being injected into the material of higher viscosity) and which is equipped with a rotatable spring stirrer in the form of a right cylindrical or right conical helix.  Specified polymers are polyurethane plastics, either dense or foamed, polyester or epoxide resins, polyvinyl chloride pastes and latex foam materials.  The contents of the cylinder are ejected by a piston 1 which when actuated compresses the stirrer S into a recess 4 in the bottom 2 of the cylinder.  In a modification (Fig. 1, not shown) the stirrer is attached to the piston.  Mixtures or reactives involving successive additives may be made or carried out by connecting two or more cylinders in series (see Fig. 4, not shown).  The apparatus may be used for batch processes as described, or by rendering the piston and outlet valve inoperative, for continuous processes (see Fig. 3, not shown).  The outlet valve may be operated automatically by the temperature of the reactive. Fillers and/or gases may be introduced into the mixing chamber.  Fig. 5 shows diagramatically an installation in which polyester and activator are supplied by pumps 14, 18 from containers 13, 17 to the premixing chamber having an agitator 20.  The mixture is introduced into the agitation chamber 23 into which isocyanate is delivered by the pump 25 from the container 24; the liquids are homogenized by the stirrer 27 which takes the form of a light conical helix, and ejected by the piston 33 actuates the hydraulic ram 32.  Specification 811,110 is referred to.
