Title: Radiation generators
Inventor: BOTT IAN BERNARD
IPC: H01J25/00
Filed: 1963-03-28
Abstract: 1,096,921. Transit-time tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 26, 1964 [March 28, 1963], No. 12348/63. Heading H1D. A choice for generating radiation in the millimetre/sub-millimetre region utilizes the interaction between a beam having a helical path under the action of a very high longitudinal magnetic field and wave modes set up in a microwave cavity. An electron beam E is projected from an obliquely disposed gun 4, 7 and is given a helical path by the high magnetic field, e.g. 2000 gauss, produced by a first solenoid 2. The beam passes into a microwave cavity formed by a coating of silver 12 on the shoulder and narrow part of the envelope 1 and enters a region of very high magnetic field, e.g. 100,000 gauss, produced by a second solenoid 11 either disposed within the first solenoid as shown, or the first solenoid may extend only over the wide part of the envelope. The radiation produced by the cyclotron motion of the electrons of the beam is obtained as a beam issuing from a quartz window 10. The beam and the second magnetic field are preferably pulsed, and the second solenoid preferably maintained in a super-conducting state by being placed in a cryostat.

Title: Press for bending sheets
IPC: B30B15/00
Filed: 1965-03-24
Abstract: 1,066,512. Press brakes. W. BEYELER. March 24, 1965 [April 24, 1964], No.12416/65. Heading B3E. A press brake has at least three jacks acting on and spaced along the movable press member, the piston-rod of each end jack extending axially through each end of its cylinder to bear on the movable member, and means to stop the movement of the piston-rods of the end jacks before those of the centre jack(s) so that the latter then act to deflect or deform the movable press member. The cylinders of two centre jacks 12 and two end jacks 11 are carried by the framework of the press and extend into openings 10 in a movable press member 7. Piston-rods 11a, 12a of the jacks 11, 12 bear on the lower parts of the openings 10 to lower the press member 7 towards a fixed member 5. The downward movement of the piston-rods 11a is halted before that of the piston-rods 12a by an axially adjustable sleeve acting as an abutment for the piston in the cylinder 11. Continued movement of the piston-rods 12a causes deflection of the press member 7, the outer ends of which are prevented, by the abutment of the upper ends of the rods 11a with the upper parts of the openings 10, from moving down. Movement of the rods 11a may alternatively be halted by a counter-pressure in the cylinders 11.

Abstract: 1,048,053. Removing fumes generated in arc furnaces. GUSSSTAHLWERKOBERKASSEL A.G. VORMALS STAHLWERK KRIEGER. March 25, 1964 [March 26, 1963; Aug. 6, 1963], No. 12622/64. Heading F4X. Control of the gas pressure inside an electric arc furnace 1, and hence the rate of fume and dust removed through the furnace flue 8, is effected by a sensing device 29 inside the furnace, which device, through a regulator 28 and motor 27, makes appropriate adjustments to the air gap between the furnace flue 8 and the exhaust hood 11 to maintain the pressure constant for a particular setting of the regulator, the latter being manually adjusted to the appropriate pressure for whichever phase of the process is taking place in the furnace. The probe acts through the regulator 28 to control operation of the reversible motor 27 which rotates a vertical screw 23 to raise or lower a bracket 15 carrying a conduit 12 at the end of which is the hood 11. The conduit 12 connects with the exhaust flue 20 by a telescopic joint. The bracket 15 and hence the conduit 12 are also pivotable about a vertical axis 20 so that they may be moved aside when the furnace is to be recharged. The horizontal part of the conduit 12 may be made telescopic to enable the suction hood 11 to be positioned over a ladle into which the contents of the furnace are being discharged. Alternatively the two working positions for the hood 11 may be arranged at the same radius from the pivot axis 20<SP>1</SP> (Fig. 7, not shown).

Filed: 1944-07-04
Abstract: 581,870. Mixing liquids in proportionate quantities. GREY, R. B., HOLLEY, A. E., and MOTT, O. E. July 4, 1944, No. 12696. [Class 86] In an apparatus for treating a liquid with another of different density in countercurrent, comprising a series of separating and mixing vessels at the same level, mixing of the two liquids in definite proportions is assured by a float 7 in each mixing vessel, which actuates shutters 10, 11, controlling the inlets 2, 3 for the less dense and the denser liquids respectively. The float 7 is mounted on a spindle 4, movable vertically in guides 5, 6 and linked to pivoted levers 12, 13 carrying the shutters 10, 11 respectively. An increase of the less dense liquid in the vessel 1 causes a fall of the float 7 to raise the shutter 11 and the shutter 10, to decrease the inflow of the less dense liquid and to increase the inflow of the denser liquid. Similarly an increase of the denser liquid in the vessel 1 raises the float 7 to decrease the inflow of the denser liquid and to increase the inflow of the less dense liquid. Specification 125,426, [Class 1 (i)], is referred to.

IPC: F02B37/00
Abstract: 132,251. Barbezat, A. Sept. 2, 1918, [Convention date]. Motor power plant.-The apparatus described in Specification 124,421 is adapted to stationary industrial motors by the addition of an electric generator which is driven from a turbine actuated by exhaust gases from the internal-combustion engine. The diagram, Fig. 3, illustrates a plant in which an internal-combustion engine M is supplied with a charge under pressure by a compressor actuated by one of a pair of oppositely rotating turbine wheels T, to which are delivered exhaust gases from the motor M. Exhaust gases from the motor also actuate the other turbine wheel, which drives an electric generator G. If required, the generator G may be cut out of action. Alternatively, the motor M may serve solely as a generator of combustion proclucts for actuating the turbine of the generator G. In this case, the products of combustion are exhausted from the motor M immediately after ignition. Means may be provided for varying the compression space in the motor M; and safety-valves may be located in the pipes A, B. To prevent an undue rise in the explosion pressure, the ignition may be retarded, the compression space may be momentarily increased by a spring-pressed piston, or a passage leading to the turbine may conduct gases from the compression space.
