Title: Improvements in electrical measuring systems
IPC: G01R21/00
Filed: 1940-06-27
Abstract: 542,442. Power measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 27, 1940. Convention date, June 27, 1939. [Class 37] For measuring the power in a radio frequency circuit, two voltages are obtained proportional in amplitude and dependent in phase on the current and voltage respectively of the circuit. The first voltage is used to produce side band components of amplitude proportional thereto, and the second to produce a radio frequency component proportional thereto, the components so produced being mixed and the resultant detected. A balanced modulator comprises two valves 13, 14 each having two control grids. A voltage proportional to the current flowing in the radio frequency circuit 10, the power in which is to be measured, is applied through a current transformer 11 to corresponding grids of the valves 13, 14 in parallel, the other two grids being fed in opposition through a transformer 15 by an oscillator 16 at constant amplitudes. A valve 18 having two control grids has one grid fed through a voltage transformer 12 with voltage proportional to the circuit voltage, the other grid being fed through a transformer 19 from an oscillator 20 at constant amplitude. A transformer 17 has its primary windings connected across the output of the balanced modulator 13, 14 and the centre tapping of its tuned secondary winding fed through a transformer 22 with voltage of the original frequency from the output of the valve 18. The tuned secondary circuit feeds one grid of a mixing valve 21, the other grid of which is fed through a transformer 23 with the difference frequency between the frequency of the circuit 10 and that of the oscillator 20. The output circuit of the mixer valve 21 is coupled through a transformer 24 to a detector 25. In order to avoid errors due to components of double frequency, a low pass or band pass filter 26 is provided in the output circuit of the detector. With this filter there is delivered to the input circuit of an amplifier 27 a voltage proportional to the power delivered through the circuit 10 and which may be measured by a meter circuit 28. In a modification the output current charges a condenser until the charge attains a pre-determined value, when it is discharged by a neon tube and operates a counter, which indicates the energy delivered over a period of time. The current and voltage responsive potentials applied to the grids of the valves 13, 14, 18 may be derived from series and shunt resistors instead of from the transformers 11, 12.

Title: Improvements in and connected with the driving of paper-making machines and the like
IPC: H02P5/48
Filed: 1923-04-25
Abstract: 219,397. Warburton, F. G. April 25, 1923. Speed maintaining systems. - In systems for maintaining a constant but adjustable speed-ratio between a number of motors driving sections of paper-making machinery or the like, differential devices actuated by electric motors running synchronously with and mechanically dissociated from the driving motors vary resistances which compensate for a departure from the designed speed-ratio. Fig. 1 shows three direct-current electric motors 11, two of which are required to run at a fixed speed relative to the third. Each of the two is electrically connected by tappings on its armature winding and slip rings 16 so as to furnish alternating current to a small synchronous motor 15 preferably situated outside the paper machine room. The motor 15 drives, through change-speed gear 19, one element of a revolving variable resistance device the other element of which is driven by a motor 17 synchronous with the third or fixed speed motor 11 the effect being to vary resistance in the field of the regulated motor when the speed-ratio departs from the normal. Specification 22897/14 is referred to.

Title: Improvements connected with rotary photogravure printing apparatus
IPC: B41F9/10
Filed: 1950-05-08
Abstract: 693,436. Printing-machines. HALLEY & SONS, Ltd., J., and HALLEY, A. M. May 4, 1951 [May 8, 1950], No. 11313/50. Class 100(ii) Inking-apparatus.-Rotary photogravure printing apparatus has the doctor blade mounted in a housing having line contact with an arcuate face of a sealing member whose centre of curvature coincides with an axis about which the housing is rockable. The apparatus comprises an image cylinder 6 mounted in bearings 8 in the end walls of a casing 9 rockable by pneumatic means so that the image cylinder contacts the printing medium 10 passing around an impression cylinder 11. The cylinder 6 dips into a tray 12 holding a volatile ink. A sealing plate 13 has pin-and-slot connection 14 with one side of the casing 9, while the other side is sealed by a doctor blade 15 mounted in a carrier 16 in a cylindrical housing 17 having line contact with a parallel cylindrical sealing member 18 between the housing 17 and the side wall of the casing 9. The housing 17 is mounted in side plates 20 which are outside the casing 9 and are rockable about the axis of the sealing member 18. On rocking the plates 20 the blade housing 17 moves around the sealing member 18 while maintaining line contact therewith. The plates are rocked by a knurled wheel 21 on a sleeve 22 surrounded bv a clamping ring 23 fixed to the casing and carrying a pinion 24 meshing with an arcuate rack 25 on the side plates 20. By rocking the blade housing and moving first the sealing plate 13 then the upper parts of bearings 8, the image cylinder can be changed for another of different diameter. The blade housing 17 may be rotated about its axis by a hand wheel 26 to adjust the angular setting of the blade. The wheel 26 is carried by a sleeve 27 carrying a pinion 28 meshing with a pinion 29 rotatable about the trunnions 19 of the housing 17. The pinion 29 carries pins 30 which engage slots in a disc 31 keyed to the trunnions 19, so that relative movement between the pinion 29 and the disc 31 may take place as described in Specification 693,437. The blade 15 may be removed by rotating the blade housing 17 about its axis. Re-setting of the blade is brought about by a spring-loaded locking plunger 32 engaging an enlargement 34 of the sleeve 27 to lock the hand wheel 26. The plunger 32 is carried by a housing 35 having a slot engaging a pin 36 to set the housing relative to the side plates 20 and so allow for settings between adjacent radial holes. Movable with the plates 20 are sealing plates 37 integral with ink shoots 38. These shoots have an inclined upper surface and carry excess ink wiped away from the cylinder 6 by the blade 15 to the interior of the casing. The sealing plates 37 rock with end plates 20 about the longitudinal axis of the sealing member 18 and the underface 39 of each shoot is arcuate to give close contact with the trunnions of cylinder 6.

Abstract: 825,852. Screw pumps; gas turbine plant. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. April 13, 1956, No. 11395/56. Classes 110 (1) and 110 (3). A rotary pump comprises a rotor of circular section mounted in a stationary cylinder having axially spaced inlet and outlet ports, and the peripheral surface of the rotor or the internal surface of the cylinder has at least one helical groove of substantially one turn, whereby liquid is displaced from the inlet port through the groove to the outlet port by viscosity action. It is stated that, at a peripheral speed of at least 10 metres per second, the discharge pressure tends towards a variation as the square of the speed instead of, as at lower speeds, a linear variation with the speed, and that at speeds greater than 40 metres per second the variation is substantially as the square of the speed. In the pump shown in Fig. 1, the rotor has a square screw thread 4 and the adjacent casing bore 2 is smooth, but a helical groove may be formed in the bore 2, the rotor then being smooth. The liquid enters through an inlet 36 and ports 34 and is discharged through ports 33 and an outlet 35. A frusto-conical member 37 prevents the incoming liquid from being rotated by the shaft 5. In the two-stage embodiment shown in Fig. 5, contact between the liquid and the shaft is prevented by a bearing support 59 at the inlet and by a partition 65 between stages. The partition may be omitted, rotation of the liquid then being prevented by radially disposed vanes. The pump may be used as a lubricant pump in turbines or other machinery, or as a fuel pump for a jet-propulsion engine, in the latter case being driven directly by the engine shaft without reduction gearing.
