IPC: D02G1/02
Filed: 1959-11-10
Abstract: 912,247. Finishing yarns; thread guides. KIRKLEES Ltd. Feb. 5, 1960 [Nov. 10, 1959], No. 38011/59. Classes 120 (2) and 120 (3). In a method of bulking thermoplastic continuous filament yarns by twist-crimping, two yarns pass through a single heating zone whilst false-twist is being inserted in each, thence around a single draft roller and back to the same zone through which they pass in a relaxed condition and are reheated and set before winding into a package. Each yarn is subjected to the same temperature during the insertion of the false-twist and subsequent setting in a relaxed state and both yarns receive the same treatment and consequently both have the same characteristics. The degree of relaxation is determined by the relative speed of draft roller and take-up package. As shown, yarns b<SP>1</SP>, b<SP>2</SP> from bobbins B<SP>1</SP>, B<SP>2</SP>, pass around driven roller B, through guide C, Fig. 5, to and through heating zone A whence they emerge through guide C<SP>1</SP>, each to a false-twister D<SP>1</SP> or D<SP>2</SP>, around grooved guide E and draft roller E<SP>1</SP>. The yarns return through guide C<SP>2</SP> and zone A and are taken up on package F.

Title: Improvements in Printing Machines.
Inventor: WILKINSON EDWARD
IPC: G07C1/06
Filed: 1965-09-17
Abstract: 1,152,574. Automatic date and time printing apparatus. E. WILKINSON. 16 Sept., 1966 [17 Sept., 1965], No. 39731/65. Headings B6C and B6D. A machine for printing the date or the time on tickets or cards comprises a casing 10; a supporting structure in the casing; a printing mechanism including a printing pad 19b, a printing clock unit 16 and a time-indicating impression die 16b, means for guiding a card introduced through a slot 22a in the casing to the printing mechanism; a switch 24 which is closed on the introduction of the card thus starting up drive means which move the card along the guide means to the printing position and which is opened when the card reaches the printing position thus stopping the drive means and causing the printing operation; and means for releasing the card from the printing position to a container 28 in the easing. In operation, a card is inserted through the slot 22a into the guide shoot 22 until it pressed down a trigger 24a which closes the contacts of the micro-switch 24 and energizes a relay (27) (Fig. 2, not shown) which is connected in parallel with the microswitch. The micro-switch 24 operates a motor 25 which drives rollers 23 and 23a via a wormwheel and gearing 26 thus drawing the card towards the printing position. At the same time the relay (27) energizes the coil of a solenoid 19 which is provided with an armature 19a, carrying the printing pad 19b; the armature is pulled away from the die 16b and loads a striker spring 20. When the rear edge of the card breaks contact with the trigger 24a, the motor 25 slows down and ceases to rotate the rollers 23 and 23a, and the solenoid 19 is de-energized; the spring 20 thus forces the armature and printing pad against the card, a buffer spring 21 then returning the armature sufficiently to allow the card to drop into the stack shoot 28. The mechanism is preferably mounted on platform parts 13 supported on posts 14 upstanding from bearers 15 in the lower casing part 10. The upper, 10a, and lower parts, 10, of the casing are preferably hinged together at 11 and fastened by lock and key at 12.

In Fig. 1, the armature extension 4 has a rectangular hole 8 through which a smaller rectangular bar, 6 attached to the carrier 5, extends and the surface 7 is formed on the bar 6. Four springs 9 act between the extension 5, and the carrier 5 and have lines of action outside the surface 7 so as to oppose tilting. Fig. 5, shows the rectangular surface 20 formed on the inside of the hole 8 and Fig. 7 shows how the surface can be limited by points 16 on a steel pad 15. Such a "pad" may be attached to the sides of the bar 6 (Figs. 8 and 9, not shown).

Abstract: 1,063,977. Wells &c. C. C. BROWN. Sept. 20, 1965, No. 39937/65. Heading E1F. A liner L is cemented in a well bore by sealing of the space between the liner and bore, introducing cement into the space to flow downwardly about the liner and displace well fluids upwardly through the liner, and after placing the cement closing the bore of the liner. The liner is supported in casing K by a hanger and carries an extension 10, 11, 12. A setting sleeve 13 on a pipe string carries a mandrel 15 on which is rotatably mounted a cross over head 26 fixed to a sleeve 31 resting on the extension and supporting a packer P. A sleeve valve 60 is slidable within the mandrel to control ports 33 connected to the nozzles 30 of the head 26 and has ports 64, 66a. A partial turn of sleeve 13 sets the packer P and rotation of the sleeve unscrews nut 21 to disconnect the mandrel from the extension. A plug P 1  (Fig. 3 not shown) is forced by cement down the pipe string to engage a shoulder 69 in the valve to open the ports 33 and 64 and free a valve 56 carried by the extension. After a predetermined quantity of cement has been forced into the space between the liner and the casing, a plug P 2  seats on shoulder 68 in the valve, the valve 56 resting on seat 58 to prevent hydrostatic pressure from the well fluids above acting on the cement. Wash fluid is circulated down outside the pipe string to return up through the string and the pipe string with the setting sleeve mandrel, packer and sleeve valve are withdrawn from the well, a flapper valve 48, carried by the extension, and the valve 56 closing the bore of the liner against upward or downward flow.
