The injected air may be at a temperature of 200-500‹C under a pressure of 5-20 p.s.i. and may run at a speed of 100-400 yds./min. In the apparatus shown in Figs. 1 and 3, yarn is supplied from a cone 1 by the action of feed and pressure rolls 2 and 3, a stop-motion microswitch 4 and solenoid 5 controlling the yarn to arrest the feed if the yarn stops moving through the apparatus.. The yarn is thus positively fed into an inlet nozzle 6 wherein injected hot air contacts the yarn and carries it into a heating apparatus whence treated yarn emerges through outlet nozzle 11 and passes to a reservoir 13 of cooling apparatus 12 wherein cooling and setting of yarn is facilitated and yarn withdrawn from the reservoir passes under tension bar 15 to winding apparatus 14. At each heating unit of a multistation heater, Fig. 2 (not shown) yarn is fed through nozzle 6 and hot air is injected from a tube 31 by a gun heater 30 supplied with preheated air by a tube 32 leading from a tank 33 itself supplied by air tube 34 via control valve 35, Nozzle 6 leads to tubular conduit 21 formed by convolutions 40 around tank 33 and the heating of which is augmented by electrical heating means 36. A temperature sensing device 37 in a yarn tube 38 is connected to a control, Fig. 6 (not shown) and is corelated with heater 30 to regulate the temperature of the air passing through tube 38. Inlet nozzle 6, Fig. 4, comprises a metal block 45 in which are formed yarn and air passageways 46 and 47 intersecting in such manner that no twist is added to or removed from the travelling yarn, a senser 48 and controller 49 are connected to heater 30 and tube 31 to regulate the temperature of air entering the nozzle. Outlet nozzle 11, Fig. 5, comprises a block 52 in which are formed coaxially aligned passageways 50, 51, ridged at 53 to retain conduit 21; a passageway 54 leads to opening 55 connected with a tube 56 for injection of cold air. The cooling apparatus shown in Fig. 1 may be replaced by a cooling basket comprising a convoluted spring (80) of metal or plastic. The yarn may be of nylon, acrylic, rayon, cellulose acetate, polyester or polyolefin.

Filed: 1966-12-22
Abstract: 1,213,126. Container closures. EARLE METALLISING CO. Ltd. 21 Dec., 1967 [22 Dec., 1966], No. 57384/66. Heading B8T. A plug 1, e.g. of plastics, for a container 21, comprises an outer annulus 2 which seals against the upper end of the container neck, and an inner annulus 7 defining a central pouring opening 8 above the level of the outer annulus. An integral bridging member 11 forms an intermediate trough 12 which catches any spillage, the inwardly sloping top surface 10 of the annulus 7 minimizing dripping. After inserting the plug member 1 into the container neck a screw cap 14 is pressed on to the neck until the threads 15, 22 engage. Three fins 13 extending from the outer annulus 2 of the plug 1 into the trough 12 engage an inner annular skirt 18 within the cap. Rotation of the cap leads to sealing of a central protuberance 16 in the cap against the upper surface of the annulus 7 with simultaneous impingement of an annular rib 19 within the cap against the upper surface of the plug member 1, further rotation forcing the plug member into the container neck until an annular rim 3 on the plug 1 impinges on the upper surface of the container neck 20. Once the sealing arrangement has been thus assembled with the plug member 1 permanently located within the container neck 20, the screw cap is operated conventionally. In an alternative embodiment, Figs. 5, 6 (not shown), improved sealing is achieved by modification of the co-operating surface profiles.

Title: Measuring the viscosity of a liquid product in a vessel
IPC: G01N11/06
Filed: 1970-12-10
Abstract: 1312690 Measuring viscosity KUNSTHARSFABRIEK SYNTHESE N V 10 Dec 1970 [17 March 1970] 58742/70 Heading G1S The viscosity or melt index of a resin in a reaction vessel 3 is measured by measuring the time required for a fixed volume of liquid to pass through a capillary tube 6 into or out of chamber 1, the fixed volume being the volume between two liquid level detectors associated with the chamber which produce electrical signals to start and stop a time recorder. In Fig. 1, chamber 5 is allowed to fill with the liquid in reaction vessel 3. During filling gas is passed into vessel 1 containing chamber 5, the gas entering through pipe 8 and being vented to atmosphere via pipe 7 and valve 9. When the liquid reaches a sufficient level to cover the end of pipe 7, a back pressure is produced in pipe 8 which back pressure acts on a conductive liquid in pipe 21 and breaks the circuit between electrodes K 1  and K 2  in vessel 11. Breaking of the circuit causes a timer to be started and by means of a control circuit closes port 2 of valve 14 and connects ports 0 and 1 of valve 9 together to apply gas pressure in pipe 20 to the liquid in chamber 5 to expel it from the chamber via capillary 6. The gas pressure in pipe 20 is equal to the gas pressure at the tip of capillary 6, which is sensed by tube 12, plus a pressure equivalent to the head h 2  of a conducting liquid in vessel 13. When all the liquid has been expelled from chamber 5 the pressure in pipe 20 falls and the liquid in vessel 13 rises into tube 18 to make the circuit between electrodes K 3  and K 4 . The making of the circuit causes the timer to be switched off and the measurement cycle to start again Fig. 2 shows a modification of Fig. 1 in which the electrodes K 1 - K 2  have been replaced by a pressure differential switch 24, and the electrodes K 3 -K 4  by a differential switch 25. A pressure balanced reducing valve 26 produces a pressure in line 20 a predetermined amount greater than in line 12. Alternatively the valve 26 may be omitted, line 20 may be connected to line 12 and pipe 10 may be extended to terminate below the end of capillary 6. In Figs. 3 and 4 conductivity or capacitance liquid level devices 24a, 25a are provided. In Fig. 3 liquid is allowed to enter through capillary 6 by connecting ports 1 and 2 of valve 14 and the time taken for the liquid level to rise from detector 24a to detector 25a is measured. The liquid is then expelled through capillary 6 by connecting ports 0 and 1 of valve 14 until the liquid level reaches detector 24a when a new cycle begins. In Fig. 4 ports 0 and 1 are connected to fill the chamber. When the liquid reaches detector 25a, ports 1 and 2 are connected and the time taken for the liquid level to fall to detector 25b measured, a new measuring cycle then being commenced.

Abstract: 1448978 Mechanical spot-type disc brakes; wear-adjusting; lubricating GIRLING Ltd 12 Dec 1973 [22 Dec 1972] 59441/72 Heading F2E In a spot type disc brake of the kind including a clamp assembly 9, 10, 11, Fig. 2, movable axially with respect to a stationary member 1, the first beam 9 incorporating applying-means, e.g. 15 for applying a friction pad assembly 3 directly, the other friction pad assembly 4 being applied by reaction, the applying means comprises a housing 16 screw-threaded at 19 in the first beam 9 and containing components whose combined effective length is increased on brake application only, and adjuster means are incorporated for rotating the entire housing 16 on brake release when rotation of one component exceeds a predetermined value. Brake application.-As shown in Fig. 2, friction-pad-assembly 3 is advanced into contact with the disc (not shown) by rotating mechanically a spindle 25 whose inner end consists of a ramp plate 22 co-operating through recesses 23 and balls 24 with a ramp plate 21 keyed against rotation relative to housing 16. Friction-pad-assembly 4 is applied by reaction through a thrust bearing 29, a shoulder 28 between head 17 and stem 18 of housing 16, the actuating beam 9 in which the housing is screwed, a pair of draw bars 11 and the reaction beam 10. Two actuator assemblies 16 to 25 for the one pair of friction pad assemblies 3, 4 are provided, the spindles being rotated in opposite directions by levers 37, Fig. 1, moved by cable 42 from actuator 43. Lever 37 has a nut member 35, Fig. 3, secured to spindle 25 by pin 36, Fig. 1, and between nut member 35 and housing 16 the adjacent part of spindle 25 is surrounded by a spring washer 34, a resilient 0-ring 41 forming a friction clutch and retained by a washer 39 and circlip 40, a sleeve member 31 and a oneway clutch 38. A clutch face 32 at the inner end of sleeve member 31 formed with teeth or dogs is urged into engagement with a similar clutch face 33 at the end of housing 16. In normal brake operation, spindle 25 entrains sleeve 31 through 0-ring 41, so clutch face 32 rotates relative to clutch face 33, the clearance between teeth defining the desired brake clearance. When pad wear has occurred, spindle 25 is rotated through a greater angle than normal on brake application, but sleeve 31 is held by clutch engagement at 32, 33 so spindle 25 slips relative to 0-ring 41 and sleeve 31, one-way clutch 38 permitting over-running in this direction. On brake release, spindle 25 must rotate an equal amount back again, so after the clearance between the teeth on clutch faces 32, 33, has been taken up, sleeve 31 is entrained by spindle 25 through one-way clutch 38, and in turn rotates housing 16 in screw-threaded bore 19 of actuating beam 9 through clutch faces 32, 33. Such rotation is in the sense to move housing 16 nearer the disc. A bearing 46 for spindle 25, Fig. 3, and lubricating drillings 44, 45 are provided. The mechanism provides for re-setting.
