Platen-machines; ruling-appliances; printing-surfaces.-Relates to apparatus for setting-up and printing music of the kind in which the types are composed upon a magnetic table carrying lines, which represent the musical staves, the printed impression from the types being reduced in size by photography. The music is produced on a continuous band of paper in two stages, the notes being first printed by means of a platen press, and the stave lines being then printed by means of the rotary device. Certain signs, such as slurs, braces, and ties for quavers, may be added by means of stencils and an air-brush. (1) The printing-apparatus consists of a magnetic plate or table A, Figs, 1 and 2, which can be traversed by rack-mechanism across a table 1 to bring it beneath the platen 24 of the press, which is operated by a screw 22 having weighted arms. The magnetic table consists of a flanged plate 7, on which is disposed a coil of conducting-wire 8. A steel plate 10 is connected to the plate 7 by steel pole-pieces 12, which are separated from the plate 10 by sleeves 13 of non-magnetic metal, such as aluminium. Across the plate 10 are stretched cords 14, Fig. 4, representing the stave lines, which are engaged by notches in the underside of types 17. The bars of the music are formed bv notched bars 17b. The magnetic table may be formed from parallel bars of magnetic metal separated by bars of non- magnetic metal or alloy. The paper is drawn from a roll 27, and passes beneath the platen and between rollers 29, 30, which are rotated by suitable means, and is finally wound on a reel 31. Pairs of rollers 28<a>, pressed together by eccentrics, stretch the paper beneath the platen. A box 20, Fig. 2, is provided for containing the types. (2) The roller 29 is formed with ridges which print the stave lines, and is inked by rollers 32, 34. Types.-The types are preferably formed in one piece of steel, but may be in two parts, one part 17<c>, Fig. 10, being of magnetic metal, and containing an insert 17<e>, which may be of type metal.

Title: Improvements in sheel fuzes
IPC: F42C9/14
Filed: 1921-02-21
Abstract: 180,422. V.M.L. Experimental, Ltd., (formerly M.L. Experimental, Ltd.), and Lucas, O. D. Feb. 21, 1921. Projectile fuzes.-Relates to a percussion fuze wherein the striker B, mounted on piston B', is of tabular form and is provided with a head b<1>, of mushroom shape and perforated with holes b<2>. The detonator C is contained in the piston C'. On discharge, the inertia pins D, D<1> break shearing-pins d<2>, d<4> and fall to the limits of their runs, releasing the ball d<1> and bolt d<3> which move under centrifugal force to release the striker piston B<1> and detonator piston C'. The striker piston then moves forward under pressure of air led through channels B, b<4> to the striker base, which offers a larger surface to pressure than does the striker head b'. The air ducts a<3>, a<2>, a', leading to the base of detonator piston C<1>, are then open, and by reason of the base having a larger area than the head, the piston is moved forwards until it is locked bv the balls c engaging by centrifugal force in the annular groove h<1>. Suction pressures at grooves a<5>, a<6> communicated by air ducts j, h also assist the forward movement of the pistons. On striking any obstacle such as the fabric of aircraft, the striker is driven on to the detonator by reason of the reduction in pressure at the base of the striker piston B<1> due to the closing of the passage B. The leak-hole b<5>, by tending to equalize the pressures acting on the striker-piston base, increases the sensitiveness of the fuze. The fuze is provided with a fixed time-action base E.

Title: Improvements in or relating to electric motor control arrangements
IPC: B66B1/12
Filed: 1954-03-02
Abstract: 774,691. Automatic control systems for induction motors. GENERAL ELECTRIC CO., Ltd., and PARTON, K. C. Feb. 24, 1955 [March 2, 1954]. No. 6094/54. Class 38 (4). [Also in Group XXXVII] The resistance in the rotor circuit of an induction motor is automatically varied to maintain a value of rotor current corresponding to a desired torque. Thus, in Fig. 1, a liquid resistor 21 in the rotor circuit of the motor 10 is adjusted by a reversible three-phase motor 34 supplied through a magnetic amplifier 27, the latter having control windings 26, 29 differentially energized from a current transformer 24 associated with the rotor circuit and an adjustable reference potentiometer 33 respectively. A D.C. source 31 supplies potentiometer 33 and a biasing winding 30 for the magnetic amplifier. Dynamic braking is initiated by supplying the motor stator from a D.C. source 17 controlled by a reference potentiometer 18 which is " ganged " with potentiometer 33 so that a desired ratio of rotor current to stator excitation is maintained for optimum braking. In a modification, Fig. 2 (not shown), reference and rotor current signals are differentially applied to the windings of a solenoid controlling a fluid pressure servo unit for adjusting the liquid resistor. The reference signal is also applied to a control winding of the D.C. braking source for the motor stator, so that optimum braking is obtained as before. In an application to a speed control system for an induction motor, Fig. 3, the fluid pressure servo 43 adjusting the liquid rotor resistance 21 has its reference winding 50 energized over a rectifier 73 in series with the load winding 68 of a saturable reactor, the latter having its D.C. control winding connected in a speed-setting loop as described in Specification 738,310. The rotor current reference in winding 50 is thus dependent on the speed error existing in the loop, whereby a gradually decreasing rotor current and hence torque is maintained as the speed set by a lever 70 is approached. At the desired speed, the residual error in the loop is just sufficient to set a value of rotor current and torque to balance the load. A control winding 51 of the D.C. braking source 17 is energized in series with reference winding 50, whereby to ensure optimum braking when this is initiated by a relay 66 in response to an overspeed. error in the loop. In the systems of Figs. 2, 3 the servo is spring biased to set the rotor resistance at its maximum value when the power supply for the motor is cut-off. In a final modification (not shown), reference and rotor current signals are opposed in a single winding of a magnetic amplifier supplying one winding of a two-phase motor for adjusting the rotor resistance. The motor is coupled to an eddy current brake for damping its movement. Balancing networks for the three-phase current transformer 24 are described.

Abstract: 679,616. Fluid-pressure servomotor-control systems. ASKANIA REGULATOR CO. Feb. 28, 1948 [Sept. 28, 1946], No. 6347/48. Class 135 [Also in Group XXXV] In an electric arc furnace in which each electrode is moved by a hydraulic servomotor controlled by a pair of solenoids, one responsive to arc voltage and the other to arc current, the rate of movement of the electrode is normally limited by a first pair of stops which may be over-ridden to allow a higher rate, in turn limited by a pair of fixed stops. Each electrode 11 is moved by a hydraulic motor 6 controlled as to speed and direction by a pivoted jet pipe 19 co-operating with port 20 or port 21. The jet pipe is controlled by a solenoid 28 energised by a current transformer 52 according to arc current, and by an opposing solenoid 29 energised by a transformer 61 according to the arc voltage. Hence the ratio of are voltage to arc current is normally held constant by the solenoid cores 36, 36a, moving on suspension spring 39, 39a, between adjustable spring stops 40, 40a. When striking the arc, or under abnormal operating conditions, one solenoid will be energised very much more than the other, and the end of the suspension spring 39 or 39a snaps past the end of the first stop 40 or 40a, as the case may be, allowing the electrode to move at a higher rate, limited by an extension of the core meeting an adjustable, rigid stop 45 or 45a. A screw 46 in the current solenoid 28 bears against the suspension spring 39 to bias the system to raise the electrode if the power fails. Specification 629,394 is referred to. The Specification as open to inspection under Sect. 91, also discloses a modification, Fig. 2, (Cancelled), in which the solenoids 35<SP>1</SP>, 35a<SP>1</SP>, act on cores at either end of a pivoted beam balance which in addition to an arm 76 operating the regulator, has an arm 75 located between a pair of spring- loaded plungers 84, 85 which act as first, yielding limits, the housings of the plungers forming fixed limits. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for measuring a quantity of liquid by weight
Inventor: NOSSITER CLARENCE FRANK
IPC: G01F9/00
Filed: 1962-02-19
Abstract: 962,148. Measuring liquid by weight. WELLWORTHY Ltd. Feb. 19, 1963 [Feb. 19, 1962], No. 6295/62. Heading G1W. Apparatus for measuring a quantity of a liquid by weight comprises a float 7 disposed in a chamber 5 containing the liquid, the float having a support 14 for a weight 8, whereby the float will sink in the liquid to an extent dependent on the value of the weight, and will displace a corresponding volume of liquid, an index pointer 9 being provided against which the level of the liquid in the chamber can be compared, and a valve 4 also being provided to enable liquid to be drawn from the chamber. The apparatus may be used to measure the fuel consumption of an I. C. engine, and in use liquid fuel is supplied to a chamber 1 which it fills to a level controlled by a float valve 2. The valve 4 is in the position shown in Fig. 1 and thus the same level of liquid is present in the chamber 5 and in a transparent manometer limb 6. A pipe 15 supplies fuel to the engine (not shown). The pointer 9 is set at the level of the liquid in the limb 6, and to conduct a test the valve 4 is turned to cut off the supply from the chamber 1 and connect the pipe 15 only with the chamber 5. Simultaneously with the operation of the valve 4 a stop-clock is started and subsequently the weight 8 is placed on the support 14 depressing the float 7 and causing the liquid to rise in the limb 6 above the pointer 9. When the liquid level again falls to the level of the pointer as the engine uses the fuel, the clock is stopped and the measured time is the time taken for the engine to use the weight of fuel equal to the value of the weight 8. A number of consecutive measurements can be made by measuring times for successive weight additions, and the valve 4 and stop-clock may be inter-coupled. An alternative mode of operation is described which avoids simultaneous operation of the valve 4 and stop-clock. A further embodiment of the invention is also described in which the weight on the float 7 displaces an equal weight of fuel to another chamber which feeds the engine, the fuel level in this chamber being known before the test, the time taken for the fuel to return to this level being measured.
