Title: Improvements in or relating to regulated electrical power supply equipment
Inventor: KELLY RICHARD
IPC: G05F1/52
Filed: 1956-12-13
Abstract: 882,169. Current measuring. STANDARD TELEPHONES & CABLES Ltd. Dec. 6, 1957 [Dec. 13, 1956], No. 38092/56. Class 37. In a balanced to ground electrical power supply equipment, separate power supply units PSUA, PSUB feed respective supply lines with direct current of substantially the same value, each unit having one earthed terminal; and magnetically controlled thermionic diodes, each having a controlling winding connected to a respective supply line, actuate current indicating devices in the discharge paths thereof in dependence on current fluctuations in the supply lines. The constant current source PSUA is monitored by magnetic diode VI having a control winding CC1 energized by the source current, and a bias winding CC2 connected in parallel with the diode discharge path between a 150-volt stabilized supply line L1 and earth. The diode current varies inversely with the source current, and centre-zero relays B, C in the cathode circuit of 071 are adapted to indicate absolute deviations of Œ 1% and Œ 5% from norm of the source current. An identical arrangement monitors the current from a second source PSUB; the two sources constituting a balanced-to-ground direct-current supply system, the negative and positive sides of PSUA and PSUB respectively being earthed. A centrezero differential relay A connected between the cathode circuits of diodes V1 and VI1 is adapted to indicate mutual deviations in the currents from the two sources. Rectifier bridges may be inserted in the source current lines and the control windings CCl, CCl1 fed therefrom, Fig. 2 (not shown), for monitoring alternating-current supply lines. The relays B, C, B<SP>1</SP>, C<SP>1</SP> may be double wound, the second windings being polarized by the stabilized supply L1. In another embodiment, Fig. 4 (not shown), each diode has a second bias winding CC3, CC3<SP>1</SP> connected in series with the control winding CCl<SP>1</SP>, CC1 of the other diode. In a further embodiment, Fig. 5 (not shown), each diode has a second bias winding CC4, CC4<SP>1</SP> inserted into the cathode circuit of the other diode. Specifications 629,542, 642,375, 768,029 and 776,550 are referred to.

IPC: H02K23/54
Filed: 1968-08-10
Abstract: 1,237,776. Electric motors. G. QUELLET. 10 Aug., 1968, No. 38336/68. Heading H2A. An electric motor comprises a disc-shaped winding without a magnetic core, the winding comprising at least one coil extending through the full circumference of the winding and having a substantially polygonal shape without radially extending portions. As shown, a continuously rotatable D.C. motor comprises eight stationary permanent magnets 3 and a rotatable winding comprising seven superimposed square coils 9, the coils being mutually angularly spaced by an angle of 2#/7 and being connected to commutator segments 10 contacted by mercury brushes 12. In a modification, the winding is stationary and the magnets rotate. The coils may be made of wire, may be etched or cut out of sheet metal, or may be printed circuits, and may be mounted between two plastics material supports 7, 7<SP>1</SP> as shown, or, alternatively, may be completely embedded in plastics material with a layer of insulating material between adjacent coils. A modification providing limited angular displacement comprises only one coil connected directly to the motor terminals without the use of a commutator. Speed control in the continuously rotating motor or position control in the modified motor is achieved using pulses derived from a photocell 14 co-operating with indicia 13, Fig. 2 (not shown), on the rotor. Alternatively, a controlling signal may be derived from a second winding and commutator similar to those shown.

Title: Improved electrical distribution network disconnecting box
IPC: H02B1/00
Filed: 1928-12-31
Abstract: 326,277. Price, J. M. Dec. 31, 1928. Junction boxes.-In a junction box, single bus-bars are replaced by duplicate independent bus-bars with the ends of similar cables arranged to lie beneath the appropriate pair of bars. The pairs of bus-bars a - d, Figs. 1 and 2, are supported upon insulating columns e in the junction box h. The arrangement shown is for a 3-phase system having 4 wires. The ends f of similar cables a<1> - - a<4> are arranged to lie between the pair of bus-bars a. The other set of ends is similarly arranged between their appropriate pairs of bus-bars. To obtain this disposition the staggered arrangement of bus-bars shown is used. To use the box for a single system all the cable ends in each group are connected to one of the adjacent bus-bars, but by connecting, in each group, two of the cable ends to one bus-bar and the other two ends to the other bus-bar, two independent systems can be obtained. Specification 13129/09 is referred to.

Title: Phase memory circuits
IPC: H03K9/04
Filed: 1959-11-16
Abstract: 882,048. Phase measurement. COLLINS RADIO CO. Nov. 16, 1959 [April 15, 1959], No. 38833/59. Class 37. [Also in Groups XXXIX and XL (c)] In phase shift telegraphy phase quadrature components of the phase shifts are synchronously detected by an oscillator 23 applying 90 degrees phase displaced oscillations to the phase detectors 21, 22 so that D.C. voltages corresponding in polarity and magnitude to the quadrature components are applied as outputs of the phase detectors to integrator circuits 25, 30. The latter feed " and " gates 33, 34 to which timing pulses are applied at the end of each phase pulse signal to sample the variable slope sawtooth output of the integrators and produce pulses of amplitudes proportional to the phase detector outputs, the timing pulses finally also restoring to an initial zero valve the sawtooth outputs of the integrators. The amplitude variable pulses are then applied to coils 37, 38 in space quadrature to produce a variable axis of remanent magnetism in a saturable magnetic disc 41 in the plane of the coils. Each change in magnetic axis produces a torque on the disc, one way or the other, which through a piezo-electric shaft 42 produces between plates capacitively coupled with the torsion operated piezo-electric shaft a positive or negative voltage applied to a bistable circuit 44 whose output indicates marks or spaces. Alternatively, the transducer 42 may be magnetostrictive, electrostrictivo, photoelectric, magnetic or capacitive. In a modification each carrier pulse is shifted in turn through one of four angles differing by 90 degrees to produce in turn corresponding angular shifts of the magnetic axis of the disc each representing a pair of signals, one for each channel. This is resolved and each component directed to a channel by a pair of circuits as in Fig. 3. The second circuit resolves at 90 degrees to the first by alternately reversing the phase of the current through one of the space quadrature coils 37, 38 by having one coil centre-tapped and either end fed through one of a pair of gates. The alternate 180 degrees error in output is then corrected by a further pair of gates operated by the same pulses that operate the first pair. Specifications 828,782, 836,930, 847,535, 871,331 and 871,332 are referred to.
Patent GB-937206-A (GB)
Title: Control system for a hydraulically operated percussion device
IPC: B06B1/18
Filed: 1959-11-17
Abstract: 937,206. Percussive tools. F. H. FLOTTMANN, [trading as INGENIEURBURO DIPL.-ING. FRIEDRICH HEINRICH FLOTTMANN]. Nov. 17, 1959 [Nov. 17, 1958], No. 38984/59. Class 124. A control for a hydraulically operated percussive tool comprises a control slide valve responsive to hydraulic pressure in the cylinder and effecting initiation of the return stroke only when the hydraulic pressure at the rear of the piston rises momentarily as a result of the impact of the piston on the tool. As shown, a hydraulic piston 5 is acted upon by pressure liquid from an annular space 2 in a control valve to produce an impact on a tool 16, the pressure liquid also acting, through an annular chamber 17a in an auxiliary valve 25 integral with the piston, and a pipe 10, on one end of the piston 6 of a control valve. A spring 9 also acts to urge the piston 6 against a stop 7. As the piston 5 moves towards the tool 16, the pipe 10 is shut off from the space 17a and connected to a vent 18. On the piston 5 striking the tool 16 a momentary rise in pressure in the chamber 4 causes the valve 6 to lift off the stop 7 and allows the full hydraulic pressure to act on the whole of the face 19 of the valve and move it, against the spring 9, to the position shown in Fig. 2. The pressure liquid now acts on both upper and lower faces of the piston 5 but, since the lower face has a greater area than the upper face the piston moves towards its initial position. When the pipe 10 is again in communication with the space 17a pressure liquid again acts on the valve 6 to move it towards the seat 7 and the cycle may be repeated. If the tool 16 is not in position the piston will cover the pipe 13 preventing pressure liquid acting on the lower face of the piston 5 and the tool will come to rest. The exhaust liquid may be used to rotate the tool.

Title: Device on machine tools for supplying thereto and discharging therefrom pallets loaded with workpieces
IPC: B23Q7/04
Filed: 1974-09-12
Abstract: 1435880 Grinding REISHAUER AG 12 Sept 1974 [17 Sept 1973] 39900/74 Heading B3D [Also in Division B8] Pallets 11 (Figs. 9, 9a) are slidably received on rails 14 mounted laterally between spaced conveyer chains 13. Each rail 14 receives a respective recess V of the pallet. Each pallet has recesses N to receive workpieces A. As described, these are thread cutting tap blanks, and are to be fed to a position in which threads are to be machined by a grinding wheel 8. The conveyer chains 13 are moved step by step by a ratchet mechanism operated by a pneumatic cylinder Z1. As each pallet reaches alignment with a cylinder Z2 it is pushed by the latter into position adjacent a member 23. This is rotated by a cylinder 23 to bring the pallet around a guide rail 25 so that it slides on to a rail 9. The latter is inclined to the horizontal and the pallet thus slides down until its leading end engages a stop 26 (Fig. 2, and 6). Indentations M in alignment with the leading workpiece A, are then gripped by members 29, 30, projected respectively by air cylinders Z4, Z5. The latter are mounted on a carriage which is movable a distance T2 by the action of an air cylinder Z6. In this way the pallet is indexed step by step along the rail 9 with a delay while each successive workpiece is unloaded at position L (by means not described or shown) and machined by a tool 8 (Fig. 2). When all the workpieces have been successively dealt with in this way the pallet is released and slides down the rail 9 to lie adjacent a member 21 which has a similar action to the member 23, and is operated by a cylinder Z7. A pneumatic, cylinder Z8 returns the pallet to the conveyer chains 13. The operational sequence of the pneumatic system is described (Fig. 11, not shown).

Title: Method and machine for making non-cumulative force spiral springs
Inventor: ALBRIGHT STANLEY L
IPC: B21F1/00
Filed: 1964-09-30
Abstract: 1,071,889. Coiling spiral springs; shearing and punching. TENSATOR Ltd. Sept. 30, 1964, No. 39903/64. Headings B3A, B3E and B3W. A close-coiled spiral spring 36 is made by feeding spring strip 4 lengthwise through guides 26, 28, 30 bending the strip sharply around the forward end of the guide 30 to pass over an arcuate surface 66 and then bending the strip to a lesser degree in the opposite direction. Steel strip is fed through a measuring device 6 and the guides 26, 28, 30 by intermittently rotating rollers 18, 20, 22, 24. As it leaves the end of guide 30, the strip is bent upwardly around a freely rotatable roller 66, beneath a shoe 90 which produces the reverse bend, and through further guides 110, 112, Fig. 2 (not shown) to a severing and punching machine 34. Roller 66 and guides 110, 112 are mounted on a horizontal slide 62 which is moved during the bending by linkage 148, 154 and a cam 178, Fig. 6 (not shown), to vary the position of the roller 66 and thus the bending radius. This facilitates the required close coiling of the spring and the reverse bending increases the radius of the coils. The cam may be shaped to move suddenly the roller 66 away from the guide 30 to provide a straight tail on the spring. The latter is severed from the strip and openings are punched in one or both ends by the press 34 having a punch and die set 40, 38 actuated from an eccentric shaft 48. The severing and punching press 34 may alternatively be mounted above or below the bending mechanism 60.
