Filed: 1971-08-04
Abstract: 1350675 Feeding fibres FIBER CONTROLS CORP 4 Aug 1971 [6 Aug 1970] 36711/71 Heading D1N In a device for feeding fibres to a card fibres entering hopper 52 are transported under a controlling gate 60 by a slatted apron 50 to a spiked lifting apron 20. The area 88 in front of the apron 20 forms a tumbling roll of fibre whose level is sensed by e.g. a photocell 92 which controls the drive 94 to the horizontal apron 50.

Abstract: In the treatment of gastro-intestinal disorders, the Na, Ca, Mg and Al salts of derivatives of DL- and L-tryptophan of the formula: <IMAGE> in X is Na, Ca, Mg or Al, n is an integer indicating the valency of X and R is a p-chlorobenzoxy or p-chlorophenyl group, show properties which are superior to those of the corresponding acids which have not been converted to a salt. The invention comprises a process for the preparation of the above salts, wherein an aqueous solution of DL- or L-tryptophan is reacted at 14-18 DEG C under alkaline conditions, due to the addition of sodium hydroxide or carbonate, with p-chlorobenzoyl chloride or p-chloro-carbobenzoxy chloride dissolved in a water-miscible organic solvent, after which the solvent is extracted with another, water-immiscible solvent. From the remaining aqueous solution, the sodium salt is precipitated by adding isopropyl alcohol, or the solution is treated with a mineral salt of Ca, Mg or Al in order to precipitate the corresponding salt (II).

Title: Travelling pneumatic cleaning apparatus for spinning frames for long fibred material such as wool worsted thread and long stapled synthetic fibres
IPC: D01H11/00
Filed: 1963-09-25
Abstract: Pneumatic cleaning apparatus, Figs. 1 and 2 (not shown) comprises an electric motor driven carriage 3 which travels continuously in one direction along, or traverses between the ends of, a track rail 2 above one or more spinning frames 1 (or rows thereof) and carries an air blower or fan housed in a spiral casing 6 each suction duct 7 of which communicates through a filter sieve 9 with a filter box 8. Suction and blowing pipes 27, 28, and 13, 14, 15, 16, 17, 18, 19, extend from box 8 and a pressure distribution box 12 and terminate in nozzles positioned adjacent the parts of the frames which are to be cleaned of waste fibres.  The material collected in the box 8 is periodically discharged therefrom (through a hopper into a static receptacle) by the action of a blast of air under the control of mechanically interlinked flaps or valves, Figs. 3-5 (not shown).  A first flap (movement of which actuates the other flaps) uncovers an aperture in an outside wall of the box; a second flap breaks the connection between the box and the suction side of the fan; a third flap simultaneously establishes communication between the box and the pressure side of the fan and breaks the connection between the pressure side of the fan and the distribution box; a series of other flaps close communication between box 8 and the suction tubes.

Title: Fluid pump
IPC: F04B43/08

Abstract: 837,617. Momentum apparatus for forcing liquids fluid pumps. FISHER, J. C. Dec. 11, 1956 [Dec. 14, 1955], No. 37749/56. Classes 8(1) and 102(2). [Also in Group XXXV] A fluid pump having an inlet and outlet for the fluid comprises two or more enclosures which are oscillated out of phase and one or a pair of fluid flow rectifiers associated with the fluid flow to and/or from each enclosure and responsive to the fluid surges produced by oscillation to maintain a substantially unidirectional pulsating flow in the outlet. In the embodiment shown in Fig. 2 the two enclosures are formed from a single tube 62 which is wound toroidally through openings 28, 48 of an inner and outer cage to provide six tubes 66 and six tubes 68 each set forming an enclosure. The inner and outer cages are axially slidable on rod 18 and rods 15 respectively and are loaded at each end by springs 70, 72 and 74, 75 respectively. The two ends of the tube 62 are connected to passages 87, 88 of a rectifier unit 80 which passages interconnect pairs of passages such as 85 provided with a ball valve such as 95. The valves of one passage of each pair allow flow from the inlet 99 towards the passages 87, 88 as shown while the remaining two valves (not shown) allow flow from the passages 87, 88 to the outlet. The two cages are oscillated out of phase by a vibrator 4 (see Group XXXV). In an alternative form the tube is wound helically on two cages which are oscillated in a rotary direction as in Fig. 5 (not shown). The passages of the rectifier may be so shaped that the ball valves may be omitted. In the embodi - ment shown in Fig. 8 three enclosures 210, 211, 212 are formed by tubes connected together at each end by headers, the enclosures being oscillated out of phase by a crank 222. The inlet to the pump 228 branches to each of the enclosures and conduits from the enclosures meet at the pump outlet 238. Each of the conduits 230, 231, 232 leading from the enclosures contains a rectifier 234, 235, 236 which may be a check-valve. In this latter pump the fluid flows through the enclosures which is not the case in the former pump. In a further modification the enclosures shown in Fig. 8 may be interconnected at one end and conduits leading from the other end open into separate conduits between two non-return valves as in Fig. 9 (not shown).
