Title: Improvements in or connected with weft replenishing looms
IPC: D03D45/20
Filed: 1939-08-09
Abstract: 532,894. Weft-replenishing mechanism. TURNER, R. G. Aug. 9, 1939, No. 22974. Convention date Aug. 18, 1938. [Class 142 (iii)] In a multicolour or other weft replenishing loom, a controller 65 or 66 is moved to operative position on indication of weft exhaustion and remains in this position until the exhausted bobbin is replaced, and is then moved back to normal position by the transferrer 13 or a member connected thereto. The invention is described in connection with looms as shown in Specifications 3271/10, 22996/10, [both in Class 142 (iii)], 500,172, 507,872, 516,950, and 517, 757. The raising and lowering of the two-compartment shuttle box acts through a lever 20 and rod 88 to move a slide 68 along a lever 35 to bring one or other of the controllers 65, 66 into a plane containing a setting lever 74 operated by a weft feeler and the electromagnet 79, a resetter rod 100 or 151 operated from the transferrer 13 through a lever 90, and a dog 60 carried by a constantly oscillating lever 55. On weft exhaustion the magnet 79 lifts the setting lever 74 which moves one controller, say 65, into operative position shown in Fig. 5. The controllers 65, 66 are held in either position by springs 71. The controller 65 can now move the dog 60 under the lug 62 on the lever 35 which will be lifted to raise the transferrer latch 51 into line with the lay bunter 49. Even if the shuttle feeler 53 revokes the transfer and breaks the coupling 40, or if the depleted shuttle has gone out of action, the controller 65 will not be moved by the rod 100 from its indicating position until transfer has taken place. In the modification shown in Fig. 7. the resetting rod 151 is operated by levers &c. 140, 143 from the thread extractor 116 which is operated by the transferrer 12b. U.S.A.

Title: Improvements in making shaped articles from polyhalogenated ethylene polymers and copolymers thereof
IPC: C08L1/24
Filed: 1955-08-09
Abstract: Filaments, foils, films, bristles, rods or tubes are produced from an aqueous dispersion containing viscose and discrete particles of a polyhalogenated ethylene polymer in which the ethylene is substituted by at least two halogen atoms of which at least one is a fluorine atom and any remaining halogen atoms are chlorine atoms, or a copolymer thereof, by extruding the dispersion into a setting medium for the viscose, the product, which may be washed and dried, being heated, preferably above the phase-transition temperature of the polymer, e.g. to 327-500 DEG  C., to decompose the cellulose and coalesce the polymer.  Halogenated polymers specified are polytetrafluoroethylene, polymonochlorotrifluoro-ethylene and copolymers of tetrafluoroethylene with ethylene, haloethylenes, propylene, halopropylenes (hexafluorinated propylene being specified in an example), vinyl compounds and vinylidine compounds.  The polymers may have end groups supplied by methanol or ethanol and may contain perfluorinated kerosene and pigments.  The polymer particle size may be from 0.005 to 1.0 microns.  The spinning solution may contain an alkyl aryl polyether alcohol or sodium lauryl sulphate. After coalescing the polymer, carbon deposits may be removed by treatment with boiling nitric acid, aqua regia or other strong acid or a mixture of nitric acid and sulphuric acid or with a mixture of nitrous oxide and oxygen at 300 DEG  to 400 DEG  C.  In examples, yarn, after the removal of the cellulose, is drawn with the aid of heated rolls up to 7 times.  The coalescing may be performed in one or more steps, the heating being effected by heated rolls or molten potassium nitrate-potassium nitrite baths.  Specifications 767,015 and 813,331 are referred to.ALSO:Fibres, films and other filamentary materials are obtained by extruding a dispersion of particles of a polyhalogenated ethylene polymer in which the ethylene is substituted by at least two halogen atoms of which one is a fluorine atom and any remaining halogen atoms are chlorine atoms, or of a copolymer thereof, in an aqueous viscose solution into a cellulose regenerating bath and subsequently removing the cellulose and coalescing the polymer by heating to above 327 DEG  C.

Title: Improvements in and relating to exploder devices for shot-firing
IPC: F42D1/045
Filed: 1946-08-08
Abstract: 615,651. Driving dynamos. DAVIS & SON, DERBY, Ltd., J., and DAVIS, W. H. Aug. 8, 1946, No. 23481. [Class 35] In a hand-operated magneto for exploding mines, the circuit of the exploders is not closed unless the driving mechanism is operated sufficiently rapidly to generate an adequate voltage. As shown, the movable contact 16a in the exploder circuit is normally held away from the fixed contact 17 by the vee groove at the top of the lever 15 (shaped as shown in Fig. 2B) pivoted at 15b. On this same pivot is a lever 13 carrying pegs 12, 14, the latter projecting into a large hole 15c in the lever 15 and the latter can be moved from the inoperative position shown in Fig. 2 to the right to enable the contacts to close as shown in Fig. 3 only if the lever 13 and hence the peg 14 has sufficient momentum and this depends on the rapidity with which a driving quadrant 10 is rotated to cause a projection 11 thereon to engage peg 12 and thereby swing lever 13. On further movement, projection 11 engages a cam 22 and restores the parts to the contact open position.

Title: Improvements in the drawing of filaments of synthetic linear polyamides
IPC: D01D5/12
Filed: 1945-09-12
Abstract: <PICT:0598820/IV/1> In order to prevent the formation of crimp in synthetic linear polyamide filaments which have been hot drawn in a heating zone at a temperature of at least 80 DEG  C. but below their melting point, the filaments are uniformly cooled as they progress in the same straight line path defined during their travel through the heating zone.  During drawing the filaments are heated preferably by radiant heat but other means such as heated air, steam, hot liquids or molten alloys may also be employed.  The uniform cooling is preferably effected by passing the filaments through a bath of cool water whereby they are cooled to a temperature below 50 DEG  C.  If desired, the cooled filaments may finally be subjected to a water- or heatsetting treatment.  The treated filaments are particularly useful for the manufacture of bristles, and the synthetic linear polyamides of which they are made are of the general type described in Specification 461,236.  In the examples, polyhexamethylene adipamide or polyhexamethylene sebacamide alone or modified with 10 per cent of a phenol-formaldehyde resin are hot-drawn between rolls 2 and 9, whilst they travel through an electrically-controlled radiant heating tube 3 heated to a temperature of 410 DEG  or 500 DEG  C.  On leaving the heating tube 3 the filaments travel through a cold water trough 5 where they are uniformly cooled.  The filaments are finally set by treatment with boiling water.  If desired, the direction of travel of the filaments in the heating tube may be reversed one or more times.

IPC: A47L15/46
Filed: 1958-07-22
Abstract: 869,375. Dishwashing machines. EDLIN & SON Ltd., W. J. R. Sept. 29, 1959 [July 22, 1958], No. 23531/58. Class 138(1). The agitator 3 located in the sump 2 of a dishwashing machine is surrounded by an upwardly extending cylindrical baffle sleeve 6 having an opening in its lower portion so that water flowing into the sump 2 can come into contact with the agitator 3. The sleeve 6 is partially closed at its upper end by a deflector disc 9 of smaller diameter than the interior of the sleeve, the disc being formed with a central hole 11 and supported by vertical fins 8 attached to the upper portion of the sleeve. By this means a regular pulsation or surge in the circulation of the water is produced. The sump 2 is also provided with a water inlet valve 14 normally kept closed by a compression spring 21 and a drain valve 15 normally kept closed by a tension spring 23, these valves being connected by link rods 16, 17 respectively to a control switch 19. The upper ends of the link rods 16, 17 are slidably engaged in closed arcuate slots 25, 26 respectively of the cam plate 18 of the switch which, as shown in Fig. 9, when in the 'off' position has a projection 28 holding the spring-loaded dolly 29 of a tumbler switch 30 so as to cut off the supply of current to the agitator motor. Upon rotating the cam plate 18 anti-clockwise until the spring arm 31 bears against the projection 28, the dolly is allowed to fall to switch on the motor and the link rod 16 lowered to open the inlet valve 14. After sufficient water has entered the machine, the cam plate 18 is rotated clockwise to its " wash " position with the spring arm 31 in one of two notches 32 on the perimeter of the plate and both valves closed. To drain the machine after the washing operation, the cam plate 18 is rotated further in a clockwise direction until the spring arm 31 enters the second notch 32 and the link rod 17 is lowered to open valve 15. In this " drain or dry " position of the control switch 19 the motor is still rumming so that the agitator 3 may blow steam from the washing chamber and dry the dishes, the machine lid being raised for this purpose.
