Title: Improvements in and relating to liquid measuring and container charging machines
IPC: B65B3/32
Filed: 1920-07-10
Abstract: 148,495. Borden Co., (Assignees of Taylor, B. E.). July 20, 1916, [Convention date]. Filling jars and like receptacles.-Apparatus for filling one or more containers with definite quantities of liquid or semi-liquid comprises a reservoir 2 for the liquid enclosed in a casing 1, which may be airtight for working under vacuum. The reservoir communicates with one or more pump cylinders 10 provided with reciprocating buckets 11 and outlet valves 13. The bucket, the bucket valve 12, and the valve 13 are independently actuated by the levers 29, 30, 31 respectively, so that during the up-stroke cf the bucket the liquid can flow from the reservoir through the bucket, and during the down-stroke the valve 12 closes the opening in the bucket and the valve 13 opens to allow the liquid to flow into the containers C. The point in the downstroke at which the valve 12 seats may be varied by adjusting its up-stroke for the purpose of varying the volume delivered. The supply of liquid to the reservoir is controlled by a float 9 connected to a valve 4 in the inlet pipe. The outlet valve 13 has a bevelled face seating on a similar face 14 on the bottom of the cylinder 10, and a cylindrical extension provided with liquid packing recesses 58 and a bevelled edge 59 co-operating with a bevelled edge 61 on the bottom of the cylinder. The containers C are fed into the casing by a shoot 62 and are moved under the outlet valves 13 by a reciprocating bar 65 actuated by a lever 79 and a reciprocating telescopic rod 84, 85, the two parts of which are connected by a pivoted spring latch 86. Should the bar 65 meet with abnormal resistance the latch is detached from the portion 85 and the portion 84 reciprocates idly. The detachment of the latch 86 from the rod 85 releases a latch 95 connected to the clutch lever 46 of the driving-shaft 43 and enables a spring 91 to disengage the clutch 43<a> from the driving-pulley 44. When the liquid in the reservoir falls too low, a float moves a latch into engagement with the bar 65 and stops the machine. The bar 65 is locked 'by a latch until the full complement of containers are in position. The containers are guided into register with the pump outlets by sets of bars 105, the size of which may be varied for containers of various sizes. A rod 111 operated by the bar 65 holds up the incoming containers until the bar 65 returns to its starting position. The filled containers are transferred to a conveyer 129.

Title: Improved method and means for crimping yarns and filaments
IPC: G01R33/07
Filed: 1950-08-24
Abstract: 705,580. Crimping yarns and filaments. ROSENSTEIN, N., and ROSENSTEIN, A. J. Aug. 24, 1950 [May 31, 1950], No. 20985/50. Class 120(3) An assembly of continuous filaments or continuous-filament yarns in "tow" or "rope" form are crimped by conveying them between limp sheathing members, such as endless bands, whilst passing through the crimping means, the sheathing members parting from the yarns after crimping and the crimped yarns being collected in a relaxed condition. As shown, Fig. 2, a number of laterally-spaced continuous filament yarns 11 are cross-leased at 10 and drawn together through a guide 17 to form a "rope" 16 which passes over a roller 23, through a tubular guide 38 and between driven pressure rollers 26, 27 which force it in crimped or folded condition into a housing 47. One side 51 of the housing is pivoted at 52 and forms a door which is pressed towards the opposite side 48 by a weighted lever 58, Fig. 3; when the housing is filled with crimped and compressed rope, door 51 yields to permit the rope to drop in a relaxed, limp, crimped condition into a collecting box 64. Cushion aprons 43, 44 of continuous filament knitted or. woven webbing are fed one on either side of the rope between rollers 26, 27 and through housing 47 to protect the yarns from the crushing action of the rollers and to form rounded bends or crimps in the yarns; alternatively the pairs of aprons or bands may be so disposed in passing between rollers 26, 27 as to provide a channel therebetween for the passage of the rope which becomes sharply crimped. The relaxed, crimped rope in container 64 is subsequently set in the crimped condition by the application of heat, pressure and moisture, a temperature of 160F to 350F being used according to the material, which may be nylon, glass, polyethylene terephthalate, or "Orlon," "Savan" or "Dynel" (Registered Trade Marks). The individual yarns in the rope are then separated and wound on to bobbins. A tow of continuous synthetic filaments may be crimped in place of the rope yarns described, the leasing step being omitted.

Abstract: 519,164. Moulding plastic materials; gelatine. GELAPRINT SOC. ANON., and STURM, R. July 16, 1938, No. 21183. [Classes 87 (ii) and 121] [Also in Groups IV and XVII] Articles such as bottle caps, containers, or boxes are made by applying to a former, rubber latex or a lacquer having a basis of an artificial resin, drying the deposited layer, applying a liquid composition comprising gelatine, a softening agent for the gelatine, and an artificial resin, partially drying the gelatine layer then treating it with a hardening agent, applying a further layer of latex or synthetic resin lacquer, drying the coating, and removing the shaped article from the former. The softening agent for the gelatine may be triacetin, a fatty alcohol of high molecular weight or an ester or ether or sulphonate thereof, or a mixture of these with one another or with glycol, glycerol, or other polyhydric alcohol, or with a sulpho-ricinoleate. The artificial resin increases the elasticity of the gelatine body, and maintains it in an elastic condition by, retaining the necessary residue of water, when as in the case of a bottle cap the article is stored in undried condition prior to being used. The artificial resin may be a polyvinyl compound or a polyacrylic ester used in the form of an aqueous emulsion. For the protective layer there may be used a vinyl chloride or vinyl benzol polymer or a polyacrylic or polymethacrylic ester and the lacquer may also contain cellulose esters or resins produced from phthalic acid, glycerol, and fatty acids. Natural rubber latex alone or together with vinyl polymers may be used. The process may be carried out by dipping the former successively into the various solutions, but spraying or other methods may be used. Bottle caps may be provided with a printed or other identification by including a portion of very thin foil having the identification mark under the final lacquer layer.
