IPC: D01H13/18
Filed: 1958-02-26
Abstract: 848,263. Stop-motion for unwinding spindles. LEIGH MILLS CO. Ltd. Feb. 25, 1959 [Feb. 26, 1958], No. 6205/58. Class 120(2).  In a twisting-frame of the dolly-roller type, wherein bobbins from which the yarns are drawn for twisting are each mounted on a shell 2 on a slidable spindle 1, each shell and the associated bobbin rotate together during normal operation, but become locked in a stationary position when the yarn breaks or fails. In normal working, the spindle is held, against the force of a spring 9, in a position where the sleeve is held clear of a fixed lug 14, by an arm 11 of a bell-crank which is itself supported by a wire 12 linked to the tilting-bracket of a dolly-roller and to the bellcrank of an adjacent similar arrangement of spindle and associated parts. When the dollyroller tilts on failure of one of the associated ends the wire is relaxed to allow the springs of associated spindles to force them down so that each corresponding shell falls for the lug 14 to engage a groove &c. in a flange 15 on the shell to stop it rotating.

IPC: H01H9/26
Filed: 1964-02-17
Abstract: 1,094,133. Switches held set and freed mechanically; press-button retractive switches. BURGESS PRODUCTS CO. Ltd. Feb. 11, 1965 [Feb. 17, 1964], No. 6483/64. Heading H2B. Press-button switches 54 of the kind described with reference to Figs. 1 to 10 in Specification 1,000,578 are each provided with a lever 87 extending through a slot 55 into a shallow box-section interlock assembly 90 on which the switches are mounted by screws 79. A latch plate 93, resiliently urged to the left by means not shown, has apertures 104 shaped to provide a camming surface 107 and a latching recess 109 for each lever 87, such that when a switch is operated the lever 87 moves plate 93 to the right and then becomes locked in position 87B thereby maintaining the switch in actuated condition. Operation of any switch thus also releases any previously latched switches. To prevent operation of more than one switch at a time bell-shaped plates 94 are arranged contiguously and pivotable about their top ends 96 such that any lever 87 pivots all the plates 94 when in actuated position 87B and thus prevents movement of any other lever 87 beyond position 88C which is insufficient for operation of the associated switch contacts. In a modification, the latch plate 93 may be omitted to provide a bank of retractive switches in which simultaneous operation of any two is prevented. In a further modification (Fig. 5, not shown) the members 94 are omitted and the slots in the latch plate are purely rectangular with individual spring-loaded latching pawls 118 pivoted on the latch plate such that switches are latched in the operated condition without moving the latch plate. In this embodiment a special " cancel " switch is provided at one end having an associated slot shaped as in Fig. 3 but without the latching recess 109. Operation of this switch then cams the latch plate to release all other previously latched switches.

Title: Improvements in electrical sorting machines for record cards
Filed: 1954-03-05
Abstract: 750,284. Statistical machines. MAUL, M. March 5, 1954 [March 11, 1953], No. 6517/54. Class 106(1). An electrical card-sorting machine of the type in which each card-receiving pocket is directly controlled by an associated sorting magnet is characterized in that in addition to each magnet directly controlling the selection of its associated card pocket a plurality of magnets energized simultaneously by a combination of index marks, energizes, by means of associated contacts, another of the remaining magnets depending on the combination in which they are energized, and also in that their own sorting ininfluence is rendered ineffective. The cards of the type shown in Fig. 1 are posted from a magazine 11, Fig. 2, into one of five pockets 17a, 17b, 17c, 17d, 17e and a reject pocket 17f. The sorting magnets W1, W2, W3, W4, W5, Fig. 3, are energized by single index marks to actuate the rods 27a, 27b, 27c, 27d, 27e which in turn lift their associated sorting member 28a-28c in known manner to provide the appropriate sorting channel. When a combination of index marks occurs resulting in the energization of more than one sorting magnet the associated contacts W<SP>2</SP>II, W<SP>3</SP>II, &c., establish a circuit which simultaneously energizes one of the remaining magnets to open an alternative sorting channel, and de-energizes the magnets first energized, a suitable holding circuit being established by the new combination sorting magnet now energized. For example, if in the card column being analysed there is more than one hole, e.g. numeral 6, several magnets respond, i.e. W<SP>2</SP>, W<SP>3</SP>, which actuate their contacts W<SP>2</SP> I  and W<SP>3</SP> I  as well as their contacts W<SP>2</SP> II  and W<SP>3</SP> II , the former establishing holding circuits for these magnets, the latter establishing a circuit to magnet W<SP>4</SP> which interrupts the holding circuits for magnets W<SP>2</SP> and W<SP>3</SP> and establishes the circuit for magnet W4 so that the two magnets W<SP>2</SP>, W<SP>3</SP> are de-energized and only magnet W<SP>4</SP> remains energized before the card reaches the sorting blades. Accordingly by means of two sorting magnets a third magnet has been brought into operation which sorts the card according to the operation of its blade. De-energization of the magnet W<SP>4</SP> is effected by the interruption of its holding circuit by a timed contact which opens at the required point in the machine cycle.

Title: Improvements in or relating to hydraulic change speed gears
IPC: F16H39/24
Filed: 1924-03-14
Abstract: 213,247. Wingquist, S. G. March 23, 1923, [Convention date]. Clutches and speed - varying mechanism.- In hydraulic changespeed gears comprising a delivery pump, one or more receiving pumps, and automatic controlling means dependent on pressure and/ or speed conditions, the controlling means are such that after they have opened the communication between the pumps, they do not again close it until the regulating conditions have obtained such values as to secure continuous running with the communication closed. Sliding vane or radial cylinder pumps may be employed. In a form depend. ent only on pressure conditions, a valve 17, Fig. 3, normally closing the communication between the pumps, has an annular surface 20 constantly exposed to the pressure in a chamber 8. After the valve has been opened, the whole of its end face is exposed to the pressure, so that it is only closed by its spring 15 when the pressure is considerably below that required to open it. In another form controlled by both pressure and speed conditions and in which three speeds are provided for, valves 17 are provided for each of the receiving pumps 4, 11, Fig. 5, and 4, 22, these valves being free to be opened by pressure so long as certain speeds are not exceeded. When the first predetermined speed is exceeded, valves 25 are moved outwards by centrifugal force, the inside of the valves 17 being thereby exposed to pressure through channels 18, 31, so that the valves 17 are closed by their springs. When a second speed is exceeded, the valves 17 of the second receiving pump are closed in a similar manner. In a form controlled by speed conditions only, the controlling valve 34, Fig. 8, is balanced as regards pressure conditions, and is acted on by centrifugal force and a spring 33. In the form shown in Fig. 9, the controlling valve 39 is exposed to pressure, and is acted on by centrifugal force and a, spring 38; further, an auxiliary valve 42 is provided, such valve being acted on by centrifugal force, a spring 43 and the pressure in a chamber 50 with its inner end of greater area than its outer end, and being provided with braking blocks 47 acted on by adjustable springs 46. In the outer position of the auxiliary valve, pressure is admitted to the inner face of the valve 39, which is then held closed by its spring. In a modification of this form, springs are dispensed with, and both valves are acted on by centrifugal force and pressure only.

Filed: 1948-03-02
Abstract: 647,436. Rectifying. MASCHINENFABRIK OERLIKON. March 2, 1948, No. 6602. Convention date, March 5, 1947. [Class 38 (ii)] Regulation of the D.C. voltage output of a mercury arc rectifier is effected by connecting the primary 1 of the rectifier transformer in star and providing the transformer with a free magnetic path to give magnetic leakage and a forced duration of current conduction by the anode, switching means being provided which permit the forced current conduction to be nullified. In the arrangement described a tertiary winding 2 in open delta may be closed by a switch 5 and the secondary winding 3 connected to an interphase transformer 4 is arranged in triple single phase, full-wave connection with switches 6 which when closed convert the secondary to a six-phase star connection. For the lowest voltage step all switches are open. For the next voltage step switch 5 is closed, giving normal triple singlephase connection. For the third step the interphase transformer 4 is short-circuited by switches 6 and switch 5 is opened. Finally switch 5 is again closed and operation is effected under six-phase connection. To obtain stepless transfer the tertiary winding 2 may be closed through an oscillatory circuit comprising selectively-controlled condensers C and a saturable inductance L, and the interphase transformer provided with a secondary winding which is gradually short-circuited through a variable impedance 8. A further voltage step between the third and fourth steps may be obtained when using a double six-phase connection by making a triple four-phase system from the six single-phase system. Instead of short-circuiting the tertiary winding one of the star windings may be short-circuited outside the transformer to the neutral point through a multi-phase choke coil.

Title: Improvements in or relating to the production of powdered metals
IPC: C09C1/62
Filed: 1953-03-11
Abstract: Powdered metals and/or alloys are produced by direct gas reductions of metal salts in solution.  The process comprises the solution of the dissolved salt of the metal to contain (a) a total concentration of the metal up to 200 g/l but less than at which, in the absence of a partial pressure of a reducing gas, a compound of the metal will precipitate while heating to above 250 DEG F., (b) at least a part of said dissolved metal as a soluble gas reducible ion, (c) a hydrogen ion concentration up to that equivalent to a 20 per cent free sulphuric acid solution but less than that at which precipitation of the metal in a form other than elemental metal powder occurs under reducing conditions and (d) a compatible electrolyte (acid or salt furnishing a gas-reducible ion without causing precipitation or crystallisation of the dissolved components); subjecting the thus determined solution to a non-sulphurising reducing gas (e.g. H2, CO) at a pressure of at least 50 p.s.i.g. and maintaining a total pressure to prevent boiling; providing a material capable of reacting with acidic ions to control the pH value to precipitate elemental metal; and collecting the precipitated metal powder.  The soluble gas-reducible ion may be an ammine or an anion complex such as sulphates or carbonates.  The solvent may be aqueous or organic e.g. alkanols, ethers, ketones, esters, alcohols, methanol and isopropanol.  Complexes of ammonia with cobalt, nickel and copper are fully treated as specific examples.  Methyl amine, ethyl amine, ethylene diamine and pyridine are also disclosed as suitable amines. The reducing gas is preferably H2 and/or CO, and agitation whilst reducing the complexes is desirable.  The invention is applicable to metals having a reduction/oxidation potential between cadmium and silver inclusive and being capable of forming a complex cation with ammonia in an aqueous solution, e.g. Cu, Co, Ni, Ag, Hg, Cd, Zn, and Mn.  Specification 757,320 is referred to.
