Title: Sliding clasp fastener stringers
Inventor: AUSTIN CHRISTOPHER FREDERIC
IPC: A44B19/40
Filed: 1969-06-03
Abstract: 1,247,252. Knitting machines; warp knitted fabrics. LIGHTNING FASTENERS Ltd. 26 May, 1970 [3 June, 1969], No. 27970/69. Headings D1C and D1K. [Also in Division E2] A method of making a sliding clasp fastener stringer comprises locating a series 22 of coupling elements by means of a tubular guide 24 adjacent a longitudinal edge of a carrier tape as it is warp knitted, and knitting in the tape at least one yarn 20e which passes at least partially around the series 22 and interlinks with the other tape yarns 20 to secure the coupling elements. A warp knitting machine for this purpose comprises five yarn guides 12 movable in a controlled manner by guide bars 13 reciprocably mounted in supports 14 secured to a bracket 15 which is keyed to a shaft 16 and oscillated about axis 17 by a crank 18. A row of latch needles 11 are slidably mounted in a trickplate 10 and the lower end of the tubular guide 24 through which the series of coupling elements are fed, e.g. by a ratchet-operated wheel, is located adjacent a longitudinal edge of the tape 21 being knitted and can be reciprocated between two needles 11 (Fig. 6) to assume the position shown in Fig. 4. The swinging movement of the guide 24 is achieved by means of yarn guide 12d. The fabric of the tape is knitted by yarns 20 and the yarn 20e is guided by the yarn guide 12e which is reciprocated through the row of needles together with the tubular guide 24 and laps the needles adjacent the tubular guide when in the position of Fig. 4. With the yarn guide 12e in its displaced lateral position (Fig. 6) the tubular guide 24 and yarn guide 12e are returned to the position of Fig. 1 which loops the yarn 20e about the guide 24 when the needles 11 are then moved downwardly and upwardly to knit one course during which the yarn 20e is drawn from the lower end of guide 24 to encompass the series of coupling elements between two interlocking heads. Typically the lapping of the yarn 20e may be arranged such that three courses of the tape are knitted to each pitch of the coupling elements with the yarn 20e lapping the tubular guide twice in every three courses so that two loops encompass each coupling element. In a second embodiment the tubular guide is retained in a fixed position and a yarn guide is reciprocated such that it loops the yarn around adjacent needles to secure the coupling elements.

Title: Well drilling equipment
IPC: E21B19/08
Filed: 1930-09-19
Abstract: 361,483. Welldrilling plant. WILKINS, R., 1001, Pine Street, San Francisco, U.S.A. Sept. 19, 1930, No. 28032. [Class 85.] In a well-drilling plant with driving means including an electric induction motor, the rotation of one element of which controls the feed of the drill while the rotation of the other element rotates the drill, whereby the rate e o f feed and torque on the drill may be co-related, two motors are provided and their rotors are connected, one motor serving as a main driving motor to rotate the drill while the other motor which is of the induction type with rotatable primary and secondary elements, serves to control the feed. As shown diagrammatically in Fig. 1, an induction motor 10 has its stator supplied with current through a transformer 24, and a wound rotor with an external resistance 26 ; the rotor drives the usual rotary table 14. The rotor is rigidly connected to the rotor of a similar motor, or is geared thereto so as to have a fixed relative speed, the stator 18 of the second motor being, however, adapted to rotate and being connected through a chain &c. 22 to the draw works 20 ; in operation, if the rotor speed falls, the stator 18 rotates to raise the drill stem and so reduce the resistance. In the plant shown in Fig. 3, the motor 10 drives the table 14 through gearing 43, chaine 49, 53 and bevel gearing 57 and may drive the drum 20, when hoisting casing &c. through a chain 152 and clutch 58. The stator 18 may drive the drum 20 through chain 22, sprocket 60, and clutch 59. To permit the second motor to assist the first motor when hoisting casing &c. a band brake may surround the stator 18 or means are provided to lock the sprocket 60 to hold the stator 18 stationary. A clutch may be provided to permit disengagement of the drill-driving means during hoisting operations.

A fastener comprises a single strip of resilient metal bent at a point intermediate its length, and about a line lying in its surface into two portions disposed approximately perpendicular to one another, the one portion being further bent about transverse lines lying parallel with its surface, into a U-shaped-hook 45, and the other portion being formed as a snap stud 40 with a longitudinal slot 22 opening out of the strip in the neighbourhood of the junction of the two portions so that the stud 40 is of inverted U-shape with at least one limb 41 having an external snap-engaging elbow 46. The free limb 42 of the stud may have an outwardly directed foot 44 which prevents the stud being pushed too far in use and the limb 41 may have a root of increased width for added strength at the junction of the two portions: The limb 41 may be formed with a recess 43 at the root into which the foot 44 can move to give added resilience to the stud. Resilience may also be increased by bending a portion 38 of the stud nose out of the general plane of the stud.

Abstract: 693,385. Television cameras. PYE, Ltd. Feb. 21, 1952 [Nov. 21, 1950], No. 28395/50. Class 97 (i). In a television camera as claimed in Specification 670,581, focusing is effected by a focus control member which moves the pick-up tube with respect to the lens in the operative position through a gear-box which may be selectively adjusted to any one of a limited number of different gear ratios, the gear ratio being automatically so selected in accordance with the particular lens which is positioned in the operative position that the focus control member is turned or moved through approximately the same distance for focusing the camera from close-ups to infinity irrespective of the lens which is in the operative position. The gear-box shown comprises gearwheels 1 to 4 of different diameters secured to a shaft 5 journalled in walls 12, 13. Each gearwheel has an idler gear 8 to 11 in mesh therewith. These idler gears are also of different diameters and the gear ratio is varied by moving a selector gear 7 keyed to a shaft 6 selectively into mesh with these idler gears. The shafts 5, 6 are connected between the focus control member and the mechanism for moving the pick-up tube, and the selector gear 7 may be moved by mechanism actuated by cam surfaces associated with the different lenses on the turret.

Title: Improvements in specimen mounting
IPC: G01N1/32
Filed: 1962-07-24
Abstract: Specimens are mounted for study by enveloping them in a mixture of 10-30 parts by weight of powdered abrasive having a Knoop hardness of at least 900, and 80-120 parts of a curable resin, and curing the resin.  A surface of the body thus obtained is then ground away to expose a portion of the specimen, e.g. a metallographic specimen for microscopic study.  Suitable resins are the commercially available epoxy resins.  In the example, powdered alumina less than 0.1 micron in size is mixed with a bis-phenol A-epichlorohydrin condensate diluted with butyl glycidyl ether.  Diethylene triamine is added as curing agent, and the slurry poured into brass moulds containing the specimens for examination, and left to cure.  After removal from the moulds and heating to complete the cure, the body of resin was ground to expose a surface of the specimen for polishing, etching and examination.  The specimens may be of porous materials, e.g. metals, or of graphite.

Title: Process for the production of titanium or zirconium subchlorides
IPC: C01G25/04
Filed: 1956-09-18
Abstract: Titanium or zirconium subchlorides are prepared by reacting the tetrachloride with from one to three equivalents of sodium, in a dry finely-divided sodium chloride reaction medium, the temperature being maintained between the melting-point of sodium and that of sodium chloride.  The di- or tri-chlorides may be so formed.  They may be used in admixture with sodium chloride as reducing agents or separated by dissolving the reaction product 20% hydrochloride acid, filtering the undissolved sodium chloride and evaporating the lower halide solution in vacuum.  A part of the subhalide product appears to exist as a complex or double salt with the sodium chloride. According to an example, sodium is dispersed over finely-divided sodium chloride in a stirred reactor under an argon or helium atmosphere, and the titanium tetrachloride is slowly added.  The reactants are maintained at 290-330 DEG  C.  A mixture of titanium dichloride and salt results. Further examples refer to titanium trichloride production.
