Title: Improvements in electron gun
IPC: H01J29/48
Filed: 1961-03-20
Abstract: 941,734. Cathode-ray tubes. GENERAL ELECTRIC CO. March 20, 1961 [March 21, 1960 No. 10042/61. Heading H1D. An electron gun has a relatively large area cathode 20, Fig. 4, and a decelerating longitudinally non- symmetric electrostatic hyperbolic lens 24, 26, which both modulates the beam, by electron reflection, and focuses it at a small spotdefining aperture 46 in exit electrode 28. The focusing of the beam cross-over at the defining aperture occurs at the same modulationvoltage as provides maximum current transfer through the modulating or " gate " electrode 26. The gate electrode 26 is cut away, or is formed from sheet material, to provide a conical surface 40 having an apex angle of 109 degrees, the apex of the surface coinciding with the defining aperture 46. Exit electrode 28 acts like an optical meniscus lens and has a similar conical surface 42 in back-toback relationship with surface 40. Anode 24 has a spherical surface 48, all these surfaces 40, 42 and 48 approximating to rheoretical hyperbolic surfaces. The cathode 20 and electrode 22 form a beam collimating system of the Pierce type. The beam emerging from the aperture 46 is reconverged by the lens 28, 30. In a modification the beam is reconverged by a symmetrical hyperbolic unipotential lens. In Fig. 5, the gun system is accommodated in a container 150 of which the apertured electrode 128 forms an end portion. The container 150 may be separately evacuated to a higher vacuum than that obtaining in the main portion of the apparatus to which the container is connected. In this arrangement the cathode may be of the oxide-coated type.

Abstract: 852,346. Axial-flow compressors; gas-turbine plant. SMITH & SONS (ENGLAND) Ltd., S. March 27, 1958 [March 27, 1957], No. 10050/57. Classes 110 (1) and 110 (3). [Also in Group XXXV] A system for a gas turbine engine 1, having an axial flow compressor, comprises means for reducing the fuel supply at the onset of surge conditions when a quantity, representing the ratio between the angular acceleration of the turbine and the pressure at the exit of the compressor, exceeds a predetermined value which is a function of the angular velocity of the turbine and the compressor inlet temperature. A tachometer generator provides an electrical signal indicative of the speed in line 2, whilst a temperature-responsive pick-off at the compressor intake provides a signal in line 3, and a pressure-responsive device at the compressor outlet affords a signal in line 4. These signals are combined in a function-generating device 5, the output of which is applied to a differential 7. A differentiating device 6 provides a signal proportional to the acceleration for application to a second element of the differential. The output from the device 7 is applied to an amplifier 9 for controlling a normally-open valve in the fuel system 10.

Title: Improvements in and relating to electric control systems for lifts
Inventor: SPENCE WILLIAM
IPC: B66B1/12
Filed: 1954-04-06
Abstract: 780,716. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. March 16, 1955 [April 6, 1954], No. 10101/54. Class 38 (3). [Also in Group XXXV] In a Ward-Leonard speed control system for a D.C. lift motor M supplied by a generator G, means are provided for preventing " back drop " of the lift due to gravity when the brakes are released. The generator field F1 is supplied by an amplidyne exciter A whose field F2 is energized in accordance with the difference of motor speed and speed reference signals. A step-by-step reference is derived from a D.C. source over switches K1-K3, and a measure of the motor B.E.M.F. is obtained by combining signals derived from a potentiometer P1 across the armature and from motor-generator compoles CP1, CP2. When forward or reverse contactors U or D are closed, a switch N is automatically closed to provide an initial excitation for field F2 and thus set a motor torque to counteract gravity " back drop " of the lift when the brakes are released. Switch N is automatically opened when the first speed reference is set by closure of switch K1. If the voltage applied to field F2 exceeds a reference tapped from a resistor R4, Fig. 2, supplied from a D.C. source, a bridge rectifier RB permits current flow in resistor R4, whereby the field excitation and hence the lift acceleration is limited to the reference value. The closing of a switch O to set a zero speed reference causes the motor to be regeneratively braked to a standstill. Transient feed-back signals are fed over circuits R1, C1 and R2, C2 in known manner to additional fields of the exciter A, whereby the control action is improved. The Specification states that electronic or magnetic amplifiers may replace the amplidyne exciter and that a tachometer may be employed to measure the motor speed. The invention is said to be particularly applicable to the system described in Specification 780,715.

Title: Refining of sugar
IPC: C13B30/02
Filed: 1971-04-20
Abstract: 1346614 Refining and crystallising sugar W R GRACE & CO 20 April 1971 [13 May 1970] 10179/71 Heading C6B In a sugar refinery at least a portion of at least one of the usual internal recycle streams is diverted to an air crystallisation stage where it is crystallised upon recycled sucrose - containing particles to produce a particulate, substantially dry, free flowing product. As shown in Fig.2, raw sugar is washed and melted at 24 and the resulting liquor is passed through a line 25 including defecation, clarification and decolourising stages to vacuum pans 26 from which white granulated sugar and soft sugar are withdrawn at 27, 9 respectively. The affination syrup from stage 24 with, optionally, some concentrated sweet waters, is fed by line 33 to a remelt station 32 where it is boiled to form remelt sugars which are remelted and returned through line 34 to the beginning of the process, and the final molasses is discharged at 31. The molasses or last strike syrup from the vacuum pans 26, instead of being recycled as usual to the remelt station 32, is fed to an air crystallisation apparatus 29 where it passes through a metering pump 54, Fig.4, to a centrifugal spray disc 47 by which it is distributed as mist in an enclosure 46 to which air is admitted from a heater 52. Crystallisation of the syrup is assisted by recycled sugar particles fed from a conveyer 56 to the enclosure just above the disc 47. The dried product, which contains a small proportion of invert sugar and is white or brown depending on whether or not the syrup is decolourised before reaching the air crystallisation apparatus, is discharged at 57, the finestparticles being retained in a cyclone separator 60 and the remainder passing to an outlet 58. In a modification, the affination syrup in line 33 is fed to the air crystallisation apparatus and the last strike syrup from the vacuum pans 26 is recycled through the remelt stage 32, whilst in a further modification neither the affination syrup nor the last strike syrup is recycled, both being fed to the air crystallisation apparatus.

Title: Improvements relating to band brakes
IPC: F16D65/14
Filed: 1922-04-10
Abstract: 200,567. M³ller, M. April 10, 1922. Actuated or applied by running axle or wheel; band.-The ends of the band 2 are attached by chains &c. 4 to a point P on a roller 3 which is pressed against the brake drum 1 and thus caused to rotate and tighten one of the chains 4. The opposite end of the band 2 is held by the engagement of a projection 5 with a fixed stop 6. A similar action occurs irrespective of the direction of rotation of the axle A. Fig. 2 shows an application to a railway vehicle axle. The roller 3 to which the chains 4, 4<1> are attached is carried on a lever 20 pivoted at 27, and is pressed against the drum 1 to apply the brakes by a spring 10. The spring is compressed to release the brake by the plunger of an electric solenoid 9. The braking force may be varied by moving the solenoid along a slide in the frame 12. This is effected by a screw and nut 16 under control of the driver. The supporting frame 12 is mounted concentrically with the axle A and is suspended by a link 11 from the under carriage 13. The arrangement of the lever 27, the spring 10, and the solenoid 9 may be modified, and the solenoid may apply the brake against the action of the spring. In order to reduce the consumption of current when the brakes are off, the solenoid for compressing the spring may be formed as in Fig. 5. The plunger 23 has a head 27 for bridging a non-magnetic bush 26 and so closing the magnetic circuit and enabling a weak current to keep the brakes off. The solenoid current may be regulated for applying the brakes by a switch arm controlling resistances in the circuit. A battery may be arranged in the circuit for supplying current while the vehicle is passing section insulators &c. Fig. 7 shows an arrangement in which a motor M connected to the power circuit drives a dynamo D which supplies actuating current to the bra.ke solenoid 9. A small fly-wheel F is provided to keep the dynamo running while the vehicle is passing section insulators. The motor M has two windings and starts as a series motor with the switch 35 open. When the switch is closed, the winding E generates current of reduced voltage for the field winding FM of the motor and the field winding FD of the dynamo. The controller 31 connects the winding of the solenoid 9 either directly to the power circuit of the vehicle, or to the output side of the generator D. In the latter case the current is regulated by varying the resistance in the circuit of the field winding FD.

IPC: H01G4/245
Abstract: 105,333. Philips-Brinton Co., (Assignees of Brinton, W. C.). March 23, 1916, [Convention date]. Condensers are constructed b y winding alternate strips of metal foil and dielectric on a mandrel, placing a deformable casing round the body so formed, and then after removal of the mandrel deforming the casing and its contents by subjecting them to pressure in opposite directions, expansion at right angles to the direction of applied pressure being prevented. Strips b, c, Fig. 1, of foil alternate with double strips of paper a, the foil strips being narrower than the paper. The ends of alternate foil strips are bent in opposite directions to form terminals b<2>, c<2>, and then the strips are wound on the mandrel g. A casing is slipped over the rolled strips, the mandrel is withdrawn, and a filling of cotton-duck or wire-gauze is put in its place. The whole is then compressed to any desired shape by suitable dies, the ends b<2>, c<2> being flattened by hand. When tinfoil is used, the ends b<2>, c<2> are melted down, and terminal wires are soldered on. In place of bending the ends of the strips to form the terminals, metal strips may be laid on the foil and rolled in with the foil and dielectric; where a number of layers of foil are used, the metal strips may have tongues s', Fig. 20, to engage with each foil. These strips may be placed either at the end or centrally of the foil strips. The mandrel may be flat, and where paper dielectric is used, two strips are placed between each pair of foil strips. Specification 13,135/09 is referred to. The Specification as open to public inspection under Sect. 91 (3) (a) also describes a modification in which disks of foil and paper, &c., are placed in a case 18.
