Title: Stabilisation of tetrafluoroethylene
IPC: C07C17/42
Filed: 1944-02-14
Abstract: The stability of tetrafluorethylene, containing small amounts of free oxygen, against spontaneous polymerization is improved by reducing the oxygen content to not more than 40 parts per million, preferably to 20 parts per million.  The oxygen content is reduced by subjecting tetrafluorethylene to fractional distillation and discarding the oxygen-rich fraction or by treatment with a compound which reacts with free oxygen.  Inorganic compounds which may be used include silver and chromous salts.  Organic compounds, which are preferred to be used, include those containing a multiple bonded carbon atom, for example: (1) compounds containing ethylenic linkages such as hexenes, octenes, vinyl cyclohexene, cyclohexene, unsaturated acids like naphthenic, methacrylic, crotonic, undecylenic acids and their esters, amides and salts, allyl alcohol, cinnamyl alcohol, acrolein and dioxene.  (2) Compounds containing acetylenic linkages: pentine, propiolic acid, mono and divinyl acetylenes.  (3) Compounds containing aldehydic groups: formaldehyde, acetaldehyde, benzaldehyde, &c. (4) Compounds containing a multiple bonded carbon atom not attached to a hydrogen atom are particularly valuable: methacrylic acids, a -pinene, tetrahydronaphthalene, dipentene and terpineol. In the examples, samples of tetrafluorethylene are subjected to tests, with and without stabilizers, and the results are compared.  The stabilizers used are Terpene B, tetrahydronaphthalene, benzaldehyde, octene-1, methylmethacrylate, cobalt naphthenate and a -pinene.

Abstract: 538,839. Knitting. BOOTON, Ltd., W. E., and BOOTON, W. E. Feb. 16, 1940, No. 2945. [Class 74 (ii)] A two - feed circular machine knits a stocking &c. blank having alternate courses of the leg formed of different threads and the toe pocket linkage line formed in the foot bottom. The heel pocket h is knitted by reciprocation upon one group of needles at one feed, and the toe pocket t is formed by reciprocation by an opposed group of needles at the other feed. The stocking blank is knitted from the toe upwards, the toe being knitted upon the instep needles LB at one feed 2, and after the heel has been knitted upon short butted needles SB at the other feed 1, the leg is knitted at both feeders by the needles LB, SB and intermediate needles MB. During rotary knitting of the lower part of the leg, needles SBx with still shorter butts are retained out of operation, and the yarns are floated between the ends of the two groups SB. For fashioning, the needles SBx are introduced at each end of the already operating needles, and to permit needles to be picked successively from the trailing end of a group of needles, picker mechanism as described in Specification 537,965 is provided. This picker mechanism operates upon jacks arranged beneath the needles, and similar picker mechanism is employed to introduce needles successively for forming shaped splicing areas. These areas are knitted by the short butted heeling needles SB and by the intermediate needles MB, and a picker mechanism may be provided at each feeding position to introduce the splicing needles. As described, a picker mechanism for introducing the fashioning needles to the operative path is provided only at the feeder 2. Mock fashioning marks i, k may be formed by tucking on needles equidistant from the needles introduced by the picker mechanism. Upon completion of the leg, when all of the needles SBx have been introduced, at least one reinforced course l is produced, followed by a picot edge and a welt n. The blank having been completed, the floating threads are cut away, and the toe pouch is linked to the foot bottom and the edges of the foot and leg are seamed along a line which extends upward from the toe linking line to the course l. The seam so formed may be continued as a mock seam through the tubular part of the stocking.

Title: An improved electric clock system for ships
IPC: G04C15/00
Filed: 1934-01-30
Abstract: 432,286. Clock systems. MAcEWAN, H. C., and REBBECK, F. E., Queen's Island, Belfast. Jan. 30, 1934, No. 3080. [Class 139] A clock system for ships comprises synchronous motor clocks 4 and regulating means R, F whereby the rate of operation of the clocks can be regulated to correspond to the speed of the ship east or west, so that the clocks at any instant indicate the time corresponding to the ship's longitude at that instant. A motor M, fed from the ship's D.C. supply 1 has a shunt field 2 in series with a variable resistance or speed regulator R. Field 3 of this D.C. motor provides the field for a single phase alternator A, mechanically driven by the motor. The synchronousmotor clocks 4 are in parallel with lines 5 and with a frequency meter F which'is calibrated in minutes East (gain) and West (loss), Fig. 2. If the ship is travelling, say East, at such a speed that the clocks would require to be advanced 20 minutes in 24 hours, then regulator R is set so that meter F registers at 20 minutes East. By this the clocks will be driven at a faster rate so that the hour hand rotates twice in 23 hours 40 minutes. A spring-driven clock 6, operating at normal rate, is provided for visual comparison, or this clock may indicate Greenwich time.

Title: Improved heat quantity metering device
Inventor: WESP ADAM
IPC: G01K17/12
Filed: 1961-01-27
Abstract: 934,225. Magnetic couplings. TECHEM G.m.b.H. Jan. 27, 1961, No. 3304/61. Class 35. [Also in Group XX] The heat conveyed by a fluid flowing through a pipe is measured by counting at 6 the revolutions of a rotor 4 which is immersed in a viscous liquid 3, such as a silicone oil or a mixture of such oil with transformer oil, the liquid 3 being adjacent the flowing fluid so that its viscosity is dependent on the temperature of the latter. The rotor 4 may be of ferromagnetic material and be driven magnetically by a bladed wheel 1 immersed in the flowing fluid and provided with one or more magnets 2. Alternatively the rotor 4 may be of copper or aluminium so that it is driven by eddy currents. Thus the rotor 4 may be driven by a constant torque independent of the rate of flow of the heating fluid or by a torque which is proportional to such flow. Alternatively by surrounding a copper or aluminium rotor by an iron ring the rotor may have both effects combined, i.e. its driving torque has a measure of dependence on the fluid flow. In a modification the bladed wheel is replaced by a clockwork or electric moter which operates so long as the heating system is in operation. The viscous liquid 3 may become solid below a predetermined temperature so that no rotation of rotor 4 occurs below such temperature.

Title: Improvements in and relating to wire-tying apparatus for baling, packing and the like
IPC: B65B13/02
Filed: 1937-02-04
Abstract: 489,728. Bale - wiring apparatus. WALLIS, A. R., and CHEESMAN, J. J. Feb. 4, 1937, No. 3340. [Class 45] A bale-wiring apparatus is provided with a wire-grip having a serrated surface and a smooth surface for co-operating with the free end of the wire and the continuous length of the wire respectively and means are provided for preventing the continuous length from engaging the serrated surface. As shown, the grip 14 comprises a circular disc having a part 17 of the edge milled and a part 18 of slightly reduced diameter unmilled. The disc is mounted for eccentric rotation about a stud 13 in a block 11 having an upstanding part 12 and adapted to be secured to the tensioning apparatus by a screw 29. The disc is biassed towards a gripping position with the foot 15 by a spring 23. A lever 24 is pivoted at 25 so that the surface 26 bears against the edge 17. In use, the end of a wire is placed under the milled part 17, the surface 27 of the lever 24 acting as a stop. The wire is then carried through the slot in the twisting device, around the box and under the unmilled part 18 through the twisting device again, and to the jaws of the tensioning device. The end 28 of the lever 24 prevents the accidental insertion of the continuous part of the wire beneath the part 17. After tensioning, twisting and severing, the gripper may be released by pressing a finger-plate 22 on a cover-plate 20 pinned to the disc. The disc may be formed with a plurality of eccentric apertures to enable different parts of the circumference to be used when the milled edge becomes worn. The lever 24 is double-ended and may be reversed. The twisting device may be operated as described in Specifications 472,637 and 473,014 and may be provided with an adjustable stop to prevent over-twisting. According to the Provisional Specification, the tensioning lever operates a gripping device similar to that described above except that the disc is completely serrated and the cover-plate has a depending portion to facilitate the insertion and retention of the wire.
