Title: Improvements in and relating to roll winding machines
Inventor: MACKIE JOHN KAY PRINGLE
IPC: B65H54/24
Filed: 1957-09-18
Abstract: 864,700. Winding yarns. JAMES MACKIE & SONS Ltd. Sept. 18, 1958 [Sept. 18, 1957], No. 29386/57. Addition to 864,648. Class 120(2). The travelling roll winding machine of the parent Specification is modified in that the bobbin replenishing station is disposed beyond the roll doffing station in the direction of travel of the winding units so that there will be no yarn connection between the roll and the supply package when the winding unit approaches the roll doffing station. In the arrangement shown each winding unit passes successively through a bobbin doffing station where the exhausted supply bobbin is removed from peg 22; a roll doffing station where the roll 41 is removed if it has been completed; a bobbin replenishing station where a new supply bobbin 45 is supplied from magazine 44 and a centre supplying station where a new centre 40 is supplied if the roll 41 has been previously doffed. The bobbin doffing station can alternatively be positioned between the roll doffing station and the bobbin replenishing station as indicated in dotted lines. Specifications 16032/56 and 864,654 are referred to.

Title: Improvements in or relating to telecommunication exchange systems
IPC: H04Q3/00
Filed: 1938-10-12
Abstract: 520,090. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and BRAY, F. H. Oct. 12, 1938, No. 29532. [Class 40 (iv)] In a multi-exchange system in which a call may be extended over a common tandem exchange if the direct route is not available, auxiliary impulse sending equipment is associated with the tandem junctions to send out the digits necessary to route the call through tandem, the values of the digits being determined by marking conditions applied by control relays selectively operated in accordance with the identity of the direct-junction group. In the system described, an outgoing selector of the up-and-around type has earlier contacts of levels connected to direct junctions to the various exchanges, the later contacts being connected to individual overflow circuits OC, one of which from each level is multipled to a tandem junction circuit TJC having an associated sending control switch SM which is marked by relay P individual to the overflow circuit. In one arrangement, Fig. 3 (not shown), digits transmitted by the calling party or registercontroller subsequent to the digit used for setting the outgoing selector are received by a further switch associated with the tandem junction and are recorded on condensers for subsequent transmissions under the control of SM, but in the arrangement shown, digit transmission from a register-controller is held up until the tandem digits have been sent out. When the overflow circuit is seized, relay A and marking relay P pull up over the loop, reversed battery feed over A holding up the register-controller. Relays B; ZA follow whereupon IG operates on the next opening of springs MS, so that MS and LS send impulses to magnet SM and over the tandem junction TJ. Relay Z releases IG to terminate the digit when the first. marking over is reached sm1, and SM steps by selfinterruption to its next stopping position in sm2 at which Z falls back and ZA (released by Z) pulls up again. Two more digits are sent in similar manner, switching relay TF operating in series with Z when the third marking is reached whereupon normal battery feed over junction TJ causes the register-controller to complete its sending operations. The re-operation of Z causes switch SM to step until Z is released over sm2 when it steps home over sm3. Meter RTM registers the use of the overflow circuit.

Abstract: 953,511. Raising liquids by aerating an ascending column. CAMCO Inc. Aug. 2, 1962 [Oct. 2, 1961], No. 29704/62. Heading FIR. A retrievable gas lift valve assembly for a well comprises a main gas inlet valve 36, Fig. 2A, controlled by a pilot valve 33, and a non-return valve 25, Fig. 2B, the valves being located in a valve body 11 removably mounted in a housing 9, Fig. 1, in the well tubing 3 and located by latch means 19, 20 disengageable by an upward jarring force on valve body 11. Pilot valve 33 is biassed closed by gas under pressure in bellows 45. The gas pressure in well casing 1 acts on bellows 45 via ports 10 and 27 and when the required casing pressure is attained, the pilot valve is lifted to expose the upper surface of a piston 37 connected to main valve member 36 which opens against a spring 40. When the casing pressure falls, pilot valve 33 closes and the pressure above piston 37 bleeds off via bore 41, resulting in closure of main valve 36 by spring 40. A throttle may be located in the end 36 of bore 41. When valve body 11 is lowered into housing 9, spring legs 19, carrying latch ends 20, engage a shoulder 5 on the housing and are compressed into relieved portion 16 on the valve body to permit its downward movement into the housing. When shoulder 12 on the valve body engages shoulder 5, latch ends 20 spring out between a shoulder 6 and a collar 22.

Abstract: 266,800. Tennant, W. J., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Nov. 28, 1925. Hafnium and zirconium phosphates, chlorides, and oxides.-The separation of hafnium and zirconium is effected by fractionally decomposing the complex compounds produced by dissolving the phosphates in a medium containing hydrofluoric acid or a bifluoride, whereby a precipitate of the phosphates is produced in which the proportion of hafnium relatively to zirconium is greater than in the original material. The decomposition is effected by compounds which withdraw fluorine from the complex compounds, suitable substances being concentrated sulphuric acid, boric acid, boron compounds such as borax, boron chloride and boron tri-ethyl ester, zirconium, aluminium and tin salts, compounds of molybdenum, tungsten, chromium, niobium, vanadium, tantalum and beryllium, and the sol of silicic acid. Examples describe the use of ammonium molybdate and of zirconium chloride. In the latter case the zorconium chloride is produced from a portion of the original solution by adding sodium hydroxide to precipitate the oxide. and dissolving this in hydrochloric acid. Specification 226,180 is referred to.
