Title: Improvements in or relating to the transportation of continuous filaments
Inventor: COUZENS PETER JOHN
IPC: D04H3/16
Filed: 1964-06-01
Abstract: 1,043,647. Spinning and finishing yarns; thread guides. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 24, 1965 [June 1, 1964], No. 22539/64. Headings DID and D1F. [Also in Division B5] Apparatus for transporting filaments comprises a gas ejector having a plurality of passages, each individual filament being passed through a separate passage. The ejector consists of a core 8 (Fig. 2) and an outer shell 9 (Fig. 3). The core 8 has a number of longitudinal parallel grooves 10 equally spaced around its periphery. Jet holes 12,13 towards the lower end of each groove communicate with the hollow interior of the core (Fig. 5, not shown) and enable air or other gas supplied to the tube 11 to pass from the interior of the core to the exterior. The shell 9 has a corresponding number of grooves 14, bevelled at the upper end 16, so that when the apparatus is assembled (Figs. 1 and 4, not shown) and locked by the key 18 (Fig. 3) which enters passages 19, 20, each filament has a separate path through the transporting apparatus. The apparatus may be fed with filaments from one or more spinnerets and may be mounted either adjacent to a spinneret face or some distance away as in Fig. 6 (not shown). The assembly of Fig. 6 is useful in the production of a batt of filaments especially of polyethylene terephthalate which are received from the spinneret. It is projected at collecting plate 22 to form a randomly laid batt 23 (Fig. 7, not shown). Filaments of polyamides, polyesters and polyolefins may be transported using the apparatus of the invention, which keeps the filaments apart but minimizes the accumulation of electrostatic charges and hence avoids subsequent difficulties in collection due to electrostatic repulsion.

Abstract: 780,334. Spinning mules. WHITELEY & SONS, Ltd., W. Aug. 4, 1955 [Aug. 4, 1954], No. 22586/54. Class 120(2) In order to reduce the initial tension on slubbings delivered at the beginning of the outward run of a mule carriage, the delivery rollers are given a temporary increase in speed by additional drive mechanism which .is started each time the carriage reaches its inward limit. A chain 6 is fixed at its ends to the carriage 20 and passes over sprockets 7, 8, sprocket 7 being geared through change speed gears and a clutch to the bottom delivery roller 10. By these means the rollers are driven at a speed related to the carriage speed. Mounted on the carriage is a spring-loaded plunger 35 that strikes a lever 36 of a switch 37 when the carriage is almost at the end of its inward run. The switch 37 is connected to a normally open relay 38 which includes a time delay switch adapted to cut out the relay after a short delay, say half a second. The relay 38 controls a motor 40 connected by a chain 42 to a sprocket 43 geared to the delivery roller shaft 10. Closing of the motor circuit caues the rollers to be driven to deliver an excess length of slubbing until the relay 38 breaks the circuit. The carriage is driven from a constant speed motor 2 and the spindles by'a variable speed motor 24 controlled as described in Specification 585,852.

Filed: 1974-05-21
Abstract: 1462723 Activated carbon WESTVACO CORP 21 May 1974 22696/74 Heading C1A [Also in Division C5] A particulate non-agglomerative coal, suitable for making activated carbon, has a particle size of 6 to 325 U.S. mesh, the particles being irregular in shape, an apparent density of 35 to 45 lbs./ cu. ft., an oxidation number (defined) of at least 90, and a hardness value substantially the same as the raw, high volatile, caking coal from which it is derived. It may be produced by firstly heating a fluidized bed of high volatile caking coal particles (6 to 325 U.S. mesh) in an oxidizing atmosphere containing 2-21% by volume O 2  for 10 mins. to 1 hour insufficient to render the particles non-agglomerating at 500‹ F. to less than the fusion temperature of the coal until the particles have an O 2  pick up value of from 0À1 to 0À25 lbs. per lb. of coal with a spray of water directly on to the bed to control the temperature, and by secondly heating in a non-oxidizing atmosphere at a higher temperature from 750 to 1000‹ F. to render the particles non-agglomerating. The non-agglomerating coal may be optionally carbonized (e.g. at above 1000‹F.) and then activated (e.g. with steam at 1700 to 1800‹ F.) to form activated carbon.

Patent GB-228916-A (GB)
Abstract: 228,916. Naamlooze Vennootschap Fabriek van Electrische Apparaten voorheen F. Hazemeyer & Co. Feb. 5, 1924, [Convention date]. Driving-arrangements. - In mechanism for controlling the speed of electrically-driven ring spinning and twisting frames, comprising oscillatory means connected to the speed regulator of the motor by a system of rods, a link 15 is provided with two rollers 6, 8, engaged by a cam 9 shaped in accordance, with the building-motion cam, and is connected to a lever 14 of the control system by a pin 17 on a slide, which is adjusted in the link 15 beyond both of the rollers 6, 8, whereby an abrupt reversal in movement is assured. The lever 14 is secured to and oscillates a " sun " element 10, comprising a disc, gear, or the like, geared with a " planet " element 11, which is connected by an adjustable. crank 22 and link 21 with the regulator lever 19 and receives motion, in addition to that derived from the " sun elements, from a lever 24 operated by a cam 7 on a shaft 3 which makes one revolution during the building of the cop. At starting, the crank 22 is vertical so that little vertical movement is imparted to the link 21 and the motor runs at a substantially constant speed; when the full variation is imposed during the building of the main portion of the cop, the arrangement of the rollers 6, 8 and the pin 17 ensures an abrupt reversal of the crank 22 and the adjustment is such that at such reversals a higher and a lower speed is given to the motor than is actually required, in order to compensate for the inertia of the parts.

Title: Improvements in and relating to centrifugal separators
IPC: B04B1/04
Filed: 1925-09-15
Abstract: 260,720. Empson, A. W. Sept. 15, 1925. Density separators.-A centrifugal separator for liquids has ducts which constrain the liquid to be treated to flow from the inlet to the outlet of tha separating zone in a direction substantially parallel to the axis of the drum. The upper part of the drum contains a nest of separating cones 8, and the longer lower part contains a hollow cylinder 15 carrying a series of plates or baffles 16 round its periphery. These plates 16 are grooved at their ends and fit between perforated flanges 10, 21 on the bottom and top cones 6, 20 respectively. Water and oil or other mixture for separation is fed into the central tube and passes beneath the skirt 9 of the bottom cone 6. The heavier constituent forms a layer against the wall of the drum and seals the channels 17 formed by the plates 16. The mixture travels through the channels 17, thus breaking up into a number of parallel axial streams; the heavier constituent travels to the outlet 25 and the lighter constituent to the outlet 24. The cones 8 may be replaced by radial vanes on the interior of the sealing cone 7. The drum may be tapered and the plates 16 correspondingly modified. By a suitable disposition of perforations in the flanges 10, 21, the fluid can be compelled to traverse the separating zone three or more times before its discharge. In this form of separator the channels may be formed of angle plates 26, 27, 28, Fig. 8, the middle plate 27 being raised relatively to the others to permit the fluid to flow three times along the separating zone. The plates 26, 27, 28 may be formed from a single piece of material.
