Title: Improvements relating to machine tools
IPC: G05B19/27
Filed: 1961-04-17
Abstract: 912,873. Electric programme controls. SCULLY-JONES & CO. April 17, 1961 [April 18, 1960], No. 13766/61. Class 38 (6). [Also in Group XXII] In an automatic tool-change turret for a machine tool, each tool holder is identified by rings of magnetic and non-magnetic material forming code patterns which can be sequentially compared with a coded instruction on card or tape until the correct tool has been found. Eight alternative tools can be mounted in a turret, Fig. 4 (not shown), which can be rotated to bring each tool in turn past a code reader to a position in which a transfer arm can convey the selected tool from the turret to the machine tool spindle. Each tool, e.g. 19, Fig. 1, is mounted in a carrier 10 which carries ten coding rings 20, 22 &c. The code reader consists of ten U-shaped magnetic cores, e.g. 39, Fig. 7, carrying primary and secondary windings, the coupling between which depends upon whether the code ring is magnetic or non-magnetic. Five of the ten cores are shown. All the primaries are energized via a low output impedance transistor amplifier 115 from an oscillator 101. Each secondary is connected in the base/ emitter circuit of a corresponding transistor, e.g. 174, which can be alternately biased by a corresponding change-over switch, e.g. 169, actuated by the instruction card or tape reader 156. The arrangement is such that the transistors 174 &c. only pass current when the code rings presented to the cores 39 &c. differ from those defined in the instructions. This causes a relay 188 to operate and the tool turret continues to offer tools to the code reader until the correctly coded tool has been found.
Patent GB-723683-A (GB)
Title: Improvements in building motions for forming yarn packages in textile machinery
Inventor: CLOUGH DEREK ARTHUR
IPC: D01H1/36
Filed: 1953-05-22
Abstract: 723,683. Building motions for textile spinning &c., machines. T. M. M. (RESEARCH), Ltd., and HARBENS, Ltd. May 22, 1953 [May 30, 1952], No. 13777/52. Class 120 (2). A building motion for spinning and like machines wherein yarn packages are formed by relative reciprocatory movements of yarn guides and packages comprises means for effecting reversals of the reciprocatory elements, two spaced stops for actuating such means, at least one of the stops being automatically turned to vary the distance between the stops, the reversing means and stops being reciprocated relatively to one another and the periods between reversals being determined by the distance between the stops when they engage the reversing means. In an embodiment driven by an electric motor, a shaft e<SP>1</SP>, Fig. 1, is oscillated by the motor to reciprocate a ring rail a through a chain d. The shaft e<SP>1</SP> also oscillates a pinion 18 through a chain 17 and the pinion 18 reciprocates a rack 19 carrying a mounting 20, supporting a pivoted feeler h and switches f, g that are actuated by the feeler h, when it strikes stops j, 12 to cause reversal of the motor. In the mechanism shown, the stops j, 12 consist of a plain flange and face cam respectively to produce a package c as shown, If two face cams such as 12 were used, then a package coned at each end would be produced. Two plain flanges would result in a parallel build bobbin. Flange j and cam 12 are adjustably mounted on a sleeve p that is given a partial rotation at each reversal of movement of the ring rail a due to energisation of a solenoid 10 to raise a rack z thereby turning a pinion x, a pawl t, a ratchet wheel u, a worm v and a worm wheel w. In an embodiment using a vane type hydraulic motor, such as is described in Specification 684,360, an arm 26, Fig. 4, on the motor shaft 35 is engaged through a lug 27 on the arm by one or other of stops 28, 29 which screw in nuts 30, 31 secured to arms 33 pivoted at 34 and reciprocated by chains 37 wrapped around chain wheels 36 on the shaft 35. Pressure on the lug 27 from a stop 28, 29 turns the arm 26 to actuate the motor reversing valve. If the stops 28, 29 do not move relatively to each other, a constant stroke is delivered by the hydraulic motor, but each stop is adapted to be turned by a gear wheel 38 driven from a shaft 40 intermittently turned by ratchet and pawl mechanism. Instead of the nuts 30, 31, face cams may be provided and transverse arms fixed to the stops 28, 29 to co-operate with the face cams as the stops rotate.

Title: Improved process and apparatus for connecting additional transformers to a supply circuit
IPC: H01F29/04
Filed: 1921-05-17
Abstract: 163,324. Siemens-Schuckertwerke Ges. May 14, 1920, [Convention date]. Systems depending on the use of static transformers.-In a boosting transformer system, switches and resistances are employed at each end of the primary winding in order that the transformer may be removed or the direction of boost varied without disturbing the system. The secondary winding c of a boosting transformer b, c is connected to switch contacts d1, d2 adapted to engage contacts e1, f1, g1 and e2, f2, g2 respectively. When the contact d1 engages contact e1 and contact d2 engages contact g2, the transformer b, c boosts in one direction. To change the direction of boost the contact d1 is moved to bridge contacts e1, f1 and finally engages contact f1 only in which position a resistance h1 is inserted in series with the primary winding c. Further movement of the contact d1 causes it to engage the contact g1 to short-circuit the winding c and to reduce the inductive drop in the winding b to zero. A boost in the opposite direction is obtained by causing the contact d2 to engage contacts g2, f2; contact f2 only; contacts f2, e2 and finally e2 only. The transformer is removed from the system by closing the switch i and opening the switch k. In the three-phase arrangement shown in Fig. 2, switch contacts d<1>, d1<SP>11>, d1<SP>111>, and d2<SP>111>, d2<SP>11>, d2<SP>1> are mechanically interconnected and the primary windings of the transformer are connected to a common point when the contacts g1<SP>1>, g1<SP>11>, g1<SP>111> are engaged by the movable contacts. In the modification shown in Fig. 3, the secondary windings bare short-circuited by contacts o<1>, o<11>, o<111> engaging contact bars p<1>, q<1> ; p<11>, q<11>, p<111>, q<111> when changing from one direction of boost to the other. The primary windings may be short-circuited by causing the contact r to budge the contacts s and t.

Title: Improvements relating to voltage-regulating arrangements
IPC: H03F9/02
Filed: 1949-05-27
Abstract: 668,641. Automatic voltage control systems; converters. HARMER, H. M., and COOK, F. J. Aug. 28, 1950 [May 27, 1949], No. 14260/49. Classes 38 (ii) and 38 (iv). In a system of the type described in Specification 621,203, wherein a load voltage Vr derived from an A.C. supply Vs is regulated by an inductive/capacity circuit L, C, and one element e.g. C, of which is connected in parallel with the load R and a saturable core reactor L1 to compensate for variations of the A.C. supply and the load current by reason of the variation of the relative phase displacements of the voltage components, a magnetic amplifier a, b, c which derives variable bias from the load R is arranged to provide a bias .W which not only facilitates closer regulation but also compensates for slow changes such as the ageing of the rectifiers and changes of temperature and frequency. The biasing current in W is'dependent upon the difference between two A.C. biases, one in windings b being constant and the other c being dependent on the output voltage Vr. If when the output voltage is a minimum these biases are equal and the variable bias is greater when output is a maximum, variations of output voltages provide amplified biasing for inductance L1 through transformer W, L2. A barretter B is connected in series with windings b to maintain the current in those windings constant irrespective of variations of the load voltage Vr and a resistance Rt of zero temperature coefficient is connected in parallel with windings c so as to maintain the ratio of currents in the windings constant irrespective of temperature changes. The main A.C. exciting windings a of the amplifier are supplied from a transformer T and the biasing winding W is supplied via rectifier M and further biasing windings d on the amplifier which prevents the amplifier from " inverting " and thus ensures stability about the operating point of balance. The resistance Rc is provided so as to adjust the amplifier within the working range of the regulator. The magnetic amplifier may be applied to the regulating arrangements described in Specifications 515,207, 524,565, 554,467, 555,004 and 637,663. Constant current for the windings b may be also obtained by the arrangements described in Specifications 637,518, 637,664. The effect of the windings d may also be produced by a rectifier connected between the windings b, c or by a resistance across windings b connected in series with the rectifier M. The Provisional Specification also states that permanent magnets may be used in place of windings b. Specification 493,362 also is referred to.
