Patent GB-971880-A (GB)
Title: Improvements in or relating to coil winding machines
Inventor: MAY FRANCIS WIPPELL
IPC: H01F41/06
Filed: 1962-05-16
Abstract: 971,880. Winding coils; soldering. STANDARD TELEPHONES & CABLES Ltd. May 10, 1963 [May 16, 1962], No. 18891/62. Headings B3A and B3R. [Also in Division B8] A machine for successively winding coils on the polepieces C1, C2, Fig. 4, of a plurality of coil formers, comprises a winding head 1 that is mounted above a table 5 indexing the coil formers sequentially past the winding head, there being cam means 10 for causing a traversing action of the winding head relatively to the polepieces C1, C2. The table 5 is also capable of radial movement to place each former at various radial settings permitting the winding head to act successively on the two polepieces thereon and to establish connection of the windings with tags D1, D2 on two terminal posts P1, P2, Fig. 6, of the former. A motor 12 drives a lead screw 7, through a slip clutch in a casing 8 to rotate the head 1 via gears in a casing 4. On the lead screw 7 is a nut 9 that engages a saw-toothed track on a cam bar 10, the motion of the nut relatively to the saw-toothed track causing the cam bar 10 to oscillate up and down. This oscillation is conveyed to the winding head 1 to traverse the winding on its polepiece. The device includes limit switches actuated by a nut 9 such that when the nut 9 has travelled a predetermined distance in one direction the motor 12 is reversed and the nut 9 then travels in the opposite direction. At the same time that the motor 12 reverses, the table 5 is displaced radially to bring the second of the two polepieces beneath the winding head 1. Since the direction of rotation of the winding head 1 is now reversed the winding on polepiece C2 will be in the opposite electrical sense to the one wound on polepiece C1. Further limit switches reduce the speed of the motor 12 just prior to the reversal of motion thereof to prevent breakage of the winding at reversal. A ram 6 descends during each winding to hold the former securely in position on the table 5. After each former has been wound it is passed to a soldering position having a pair of soldering irons 16 (only one iron is shown) fed with solder 15, Fig. 4, to solder the wire ends to tags D1, D2 on the terminal posts P1, P2. The formers then pass a cutting position where a pair of cutters 18 cuts the wire connection between successive formers. . Each former is finally ejected by manuallyoperated means 19 where the operator replaces the ejected wound former with an unwound former.

Title: Purification of aromatic polycarboxylic acids
IPC: C07C51/487
Filed: 1960-05-27
Abstract: Crude aromatic polycarboxylic acids, containing at least 95% by weight of a single aromatic polycarboxylic acid, the remainder being essentially oxidation by-products including colour-imparting organic compounds, are purified by a process which comprises forming an aqueous solution of an alkali metal or ammonium salt of the crude acid and passing the aqueous solution through a bed of activated carbon at a temperature above 20 DEG C., the salt having from 90 to 99.9% of the carboxy hydrogen atoms of the acid replaced by alkali metal or ammonium ions and being present in solution in a concentration from 25 to 100% of the saturation concentration at the temperature at which it is passed through the carbon and recovering the aromatic polycarboxylic acid from the carbon-treated solution. The acid is recovered from the salt solution by acidification e.g. with sulphuric, hydrochloric, sulphurous or carbonic acid.  The preferred salts are the sodium, potassium and ammonium salts.  The above process may be preceded by a chemical oxidation at a pH above 6 of the salt solution e.g. with alkali metal permanganate or hypochlorite.  In examples the purification of terephthalic, isophthalic and trimellitic acids is described. Other acids specified are trimeric, tertiary butyl-tere- and iso-phthalic, di- and tetra-chloro-terephthalic, biphenyl-p-dicarboxylic and naphthalic acids.

Patent GB-314306-A (GB)
Title: Variable electric resistance
IPC: H01C17/06
Filed: 1929-06-24
Abstract: 314,306. Howards & Sons, Ltd., and Bandli, M. June 24, 1929. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 24, 1929]. Resistance materials.-A material for a variable resistance is made by suspending a finely subdivided conductor other than carbon in a fluid binding-agent which is a non-conductor and is capable of setting, the proportion of the conductor being such that the final product will contain more of the conductor than of the non-conductor, and causing the binding-agent to set before segregation of the conductor occurs. Suitable binding-agents are those which tend to contract when giving up a solvent by evaporation, or on cooling or otherwise setting. Examples are cellulose esters or ethers, particularly cellulose acetate or nitrate and viscose, rubber, guttapercha, lacquer, natural or synthetic resins, glues, gelatin, dextrin, albumin, casein. These may be dissolved in water or a volatile solvent. Finely subdivided fibres such as agar-agar, suspended together with the conductor in water or a volatile solvent are in some cases sufficiently binding. The conductor may be a metal such as iron or nickel reduced from the oxide without fusion. Other metals and alloys or solid amalgams may be used, also oxide or oxidized ores, many minerals, and some crystals. Two or more conductors may be mixed. A volatile solvent containing metal in the colloidal state may be used, or the solvent for the colloidal solution may be used in conjunction with the solvent for the binding-agent. It is generally necessary to add finely-divided reduced metal to make up the complement of metal. Pressure may be applied during evaporation or solidification. As an example 1 part by weight of cellulose acetate is dissolved in 10 parts of acetone and the solution mixed with 11 parts of iron which has been reduced from ferric oxide by heating in hydrogen. During the mixing, part of the acetone is allowed to evaporate. The resulting viscous liquid is then poured on to a glass plate and allowed to evaporate completely. Specification 273,025 is referred to.

Title: Process for transforming aliphatic hydrocarbons into higher hydrocarbons
IPC: A63D15/08
Filed: 1931-07-04
Abstract: In the production of higher hydrocarbons according to the parent Specification, in which aliphatic hydrocarbons are heated in two stages, first to a temperature above 1600 DEG  C. for less than 0,001 second, and then to a lower temperature in apparatus having hot and cold walls, the first stage is now modified by reducing the minimum temperature to 1120 DEG  C. and increasing the maximum time of heating to 0,5 second.  In the first stage, in which acetylene is produced, it is advantageous to employ a reduced pressure down to 0,05 atmosphere, while in the second stage higher pressure, say between 0,05 and 10 atmospheres, may be used.  Examples are given of the treatment of pure methane and of a gas containing 65 per cent of methane, the cooling surface for the second stage being maintained by passing water through a tube arranged concentrically within a wider tube.

Abstract: 285,800. Soc. Anon. des Etablissements TÚcalÚmit, (Assignees of Torche, P.). Feb. 21, 1927, [Convention date]. Electric clocks.-A balance 1 is periodically given an impulse by a pin 5, balance lever 6, and magnet 24. The pin 5 is rigid with a collet 4 on the balance staff 3 and in moving clockwise enters the notch 12 at the end of the balance lever; on returning counterclockwise the pin enters a second notch 13 and contacts with a spring 14 carried on the balance lever, thus completing the circuit of the magnet 24. The latter attracts an armature 23 rigid with a collar which is loose on the shaft 7 of the lever 6 and connected by a spring 8 with the end 10 of the lever 6. This spring 8 is thereby stressed and, through the lever 6 and pin 5, transmits an impulse to the balance. A spring 21 is used to bias lever 6 against either of the banking pins 19 or 19<1>. The movements of the armature 23 may be used in any known manner to give an indication of time. Modifications are described in which (1) the spring 8 is replaced by a helical spring, (2) the flexible electric connection 25 is replaced by a semi-rigid connection, (3) two magnets and two armatures are used so that the balance receives an impulse in each direction, and (4) a horseshoe magnet is used in the adaptation of the invention to a watch. Cases, watch.-Where the invention is adapted to a watch, the movement plate is provided with a central partition, one half of the casing holding the clockwork mechanism and the other half a battery.

Title: Improvements relating to couplings for railway and like vehicles
IPC: B61G1/04
Filed: 1921-07-19
Abstract: 176,726. Mitchell, J., and Cossey, J. C. G. July 19, 1921. Couplings, automatic and non-automatic.-In a coupling for a railway vehicle ona coupler head is arranged to receive a locking-bar adapted to rotate in its own plane, within the coupler head the interior surface of the bar near its engaging end being wedge-shaped to engage with the opposing coupler hook or link; the external periphery of the bar in the form of a circular are being guided in and transmitting the draft stresses to correspondingly-formed bearing-surfaces provided on the coupler head. The curved locking-bar 5 is housed in a horizontal groove 6 in the coupler head 2 formed by the flange 8 on the coupler head and casings 9, 10 bolted to the sides. In the centre of the locking-bar 5 is a stem 16 on which a spring 15 is mounted, one end abutting against stops 17, 18 on the coupler head and the other against the abutment 19 on the locking-bar. In setting the coupling for automatic engagement, the pivoted handles 22 on the locking-bar 5 are moved round against the pressure of the spring 15 until the pivoted latch 30 is pushed into engagement with the slot 46 on the locking-bar 5 by the plunger 43. On impact of the opposing coupler, the hook 20, or link, strikes the end 41 of the pivoted latch 30 and disengages it from the locking-bar, which then revolves by the action of its spring 15 into engagement with the hook and automatically tightens the coupling, as the end of the locking-bar is wedge-shaped. To enable the coupling to be set whilst the point of the hook is still in engagement with the end 41 of the latch, a pivoted gravity latch 38 below the latch 30 engages a slot 49 on the underside of the locking-bar, which is in advance of the slot 46. On withdrawal of the nose 27 of the hook from engagement with the end 41 of the latch, the plunger 43 acts on the opposite end 42, and the point 50 pushes the latch 38 out of engagement and allows the latch 30 to engage in its slot 46. On further rearward movement of the hook, the point 27 slides up the incline 29.
