Title: Method of Converting a Tubular Knitted Fabric into Open Width Form.
IPC: D06H7/08
Filed: 1968-11-21
Abstract: 1,192,279. Slitting fabrics. BEVIS INDUSTRIES Inc. 21 Nov., 1968 [14 June, 1968], No. 55265/68. Heading D1S. A tubular knitted fabric 11 is converted in flat open width form by securing a strip of thermoplastic film 16 longitudinally to the outside of the fabric tube and slitting the fabric along that portion thereof covered by the film. As shown, the flattened tubular fabric 11, e.g. cotton, passes around a driven heated roll 13 maintained at 100-350‹F. and the heated fabric passes between rolls 14, 15. A narrow thermoplastic film 16, e.g. low density polyethylene, is unwound from a roll 17 and is positioned on the fabric as it passes between the rolls 14, 15. The fabric passes around a second drum 21 maintained at approximately the same temperature as the drum 13 to secure the film to the fabric and then around a cooling drum 24. After passing around a guide roller 25, the fabric passes around an internal separator 26 which is grooved to receive a portion of a rotary slitter 27 which cuts the fabric along the part covered by the film. The fabric is fed forwards by a roll 28 and is guided by the separator to open width form on a belt conveyor 29. The thermoplastic film prevents unravelling of the fabric edges but excess film may be stripped therefrom.

Title: Elevators
IPC: B65G47/57
Filed: 1972-12-05
Abstract: 1407846 Endless conveyers having tiltable trays SOVEX Ltd 7 Nov 1973 [5 Dec 1972] 56107/72 Heading B8A Trays 1 carried by members 4 mounted on endless conveyer chains 3, are each tiltable at a selected discharge station about a bearing 6 carried by the respective member 4 to discharge documents to a shoot 2. The arrangement is such that the free edge of the tray moves with an upward component of movement, i.e. in the opposite direction to the direction of movement of the conveyer. Each tray has a guide roller 17 which is engageable at a selected discharge station with a channel formed in a member 15 (shown in full lines in Fig. 2 in its normal position, i.e. when a tray is not to be discharged at the associated station; and shown only diagramatically in Fig. 1 in broken lines). At a station at which discharge has been selected, the member 15 is moved to the positions shown in dot-dash lines (Fig. 2), thus tilting the tray as shown in dot-dash lines in Fig. 1. The outer lip of the tray (at the limit of tilting movement of the latter) may be caused to actually overhang the upstream end of the shoot 2. The stations at which the tray is to be discharged, may be selected by push buttons and associated actuating rods 11 as described in Specification 1,217,018. Other Specifications referred to are 1,132,643, 1,098,274 and 1,098,273. In a modification (Fig. 4), instead of using the member 15 the roller 17, at a selected discnarge station, is guided by a member 21 into a fixed guide track 40. When the tray is to pass through the station without being tilted to a discharge position, the roller 17 follows a linear guide surface 43. The guide member 21 is moved into position by a linkage 19, 20 operated by the camming action of the projecting end of the appropriate selector rod 11. A further linkage 30, and latch 31, holds the guide member 21 positively in position. In a modification (Fig. 3, not shown), the latch 31 is dispensed with, and the member 21 is spring biased to the broken-line position. The linkages may be replaced by an electric solenoid system. The trays may be discharged on both rising as well as descending runs of the conveyer. The documents may be arranged to discharge selectively over the front or rear edge of the tray.

Abstract: 1,223,788. Primary cell. FMC CORP. 21 Nov., 1969 [25 Nov., 1968], No. 56985/69. Heading HIB. A primary electric cell comprises a zinc, zincbase alloy, magnesium or magnesium-base alloy anode and a cathode, e.g. of Pt or C, in contact with a depolarizer which is an ionizable acidified peroxydiphosphate preferably of NH<SP>4</SP>+, K<SP>+</SP>, Li+ or Na<SP>+</SP>. The cells do not need a separator and may be of the deferred action type. The electrodes may be placed directly into a solution of the depolarizer, or a conducting liquid, e.g. water may be added to the solid depolarizer loaded in the cell. When the depolarizer has an unprotonated anion a sufficient amount of an acidic species must be added to form HP 2 O 8 <SP>3-</SP>, H 2 P 2 0 8 <SP>2</SP>- or H 3 P 2 O 8 -.

Abstract: 1,209,400. Stable insulin source. E. LEVIN. 2 Dec., 1968, No. 57140/68. Heading A5B. A stable and solid pancreatic, product which provides an insulin source for subsequent untilisation includes comminuted pancreatic tissue material having a water content of less than 6% by weight, a fat content of less than 3% by weight and substantially no pancreatic enzymes, the material having an insulin content which is equivalent to the amount of insulin available in the corresponding amount of fresh pancreas, the insulin content retaining its hormonal activity in a manner equivalent to the hormonal activity of insulin obtained from a corresponding amount of fresh pancreas. The pancreatic tissue material is suitably beef or pork pancreas. The product may be prepared by contacting a comminuated body of fresh pancreas with sufficient acid to deactivate the pancreatic enzymes and contacting the product with a boiling organic fat solvent under reduced pressure so that the solvent boils below 100‹F., removing substantially all the water from the pancreas as a solvent-water azeotrope, withdrawing the azeotrope from the distillation zone, maintaining the pancreas in the body of the solvent until the fat of the pancreas has dissolved and separating the product. A preferred solvent is ethylene dichloride.

Abstract: 1,193,037. Conveyer stops. FORDERANLAGEN BAUTZEN VEB. 11 Dec., 1968, No. 58940/68. Heading B7L. A safety stop, for a conveyer comprising carriages 27 movable along a track 26 by traction means, consists of a flap 3 pivoted to a base-plate 1 bolted to the track, and a pair of sensing levers 12 pivoted on a shaft together with a pair of weighted levers 10, the arrangement being such that for normal traction of the carriage levers 12 rotate the shaft less than an amount required to move levers 10 over top dead centre, and on breakage of the traction means the levers 12 are causes to rotate an amount by the free running carriages more than required to move the levers 10 over top dead centre, such that a pair of rollers 17 roll off curved segments 13 and flap 3 falls, blocking subsequent carriages and actuating a switch 2 to de-energize the traction means. For normal traction a stop pin on the shaft is not forced past a resilient stop member, but for a free running carriage it is. In a modification, Fig. 3, the flap is always in the path of the carriages but pivots upwardly as they are driven past. In the event of the traction means breaking, the free running carriages rolling down the track will contact the flap and depresss it againt spring 21, thereby causing switch 2 to cut off the traction drive, the flap blocking the carriages A stop 4 prevents the flap being over depressed.
