Filed: 1971-02-11
Abstract: 1376747 Electrical monitoring systems MOLINS Ltd 8 Feb 1972 [11 Feb 1971] 4495/71 Heading G1N The mass per unit length of a rod of material, e.g. a rod of tobacco in a cigarette making machine, is monitored by passing the rod through a waveguide section between a micro-wave source and a detector, the waveguide section being of such narrow cross-section that the radiation is propagated therethrough in the evanescent mode. As shown, two similar waveguides 4, 5, each having apertures 13, 14 therethrough, are provided, the radiation through each being provided from a single source I via a directional coupler 2. Tobacco passes through one only of these apertures. Two detectors 6, 7, each having diodes 8, 9, are provided, their outputs being applied to respective amplifiers 10, 11. The source preferably includes means for modulating the micro-wave output, thereby allowing the amplifiers 10, 11 to be A.C. amplifiers. Diodes or other detectors may be provided at the amplifier outputs to provide D.C. voltages which are subtracted at 16 to provide a single signal representing the density. Since tobacco normally contains moisture which affects the results obtained by the device described above, in the device shown in Fig. 2 there is provided a further waveguide 123 having a separate micro-wave source 121, of different frequency to the source 101, connected to a "magic- T" junction 122, and intersecting the waveguides 104, 105 at the apertures. Two detectors 124, 125 are provided, their outputs being applied to respective amplifiers 126, 127. Amplifiers 110, 111, 126, 127 are connected to respective filters 112, 113, 128, 129, the outputs of 110, 111 being compared at 114 and of 128, 129 at 130. The two equations, having as unknowns the volume of water and the volume of tobacco, are solved in a device 131.

Patent GB-708434-A (GB)
Title: Improvements in or relating to electron microscopes
Inventor: THEILE RICHARD
IPC: H01J31/28
Filed: 1951-03-02
Abstract: 708,434. Electron microscopes. PYE. Ltd. May 30, 1952 [March 2, 1951], No. 5129/51. Class 39(1) [Also in Group XL(b)] In electron microscope apparatus the electron image of the specimen is used to lay down a charge image on a storage target and the target is scanned by a separate electron beam to produce an output signal which is fed to a picture reconstituting cathode ray tube. In the form shown the composite stream emerging from the object falls on charge storage electrode 4 and builds up a charge image thereon and the electrode 4 is then scanned by electrons from gun 7 to produce an output signal from signal plate 5 across resistor 10. The scanning beam at the same time partially or wholly erases the charge image. The output voltage variations are fed to an amplifier 11 and the amplified output modulates the beam of a cathode ray reproducing tube 12 which is scanned synchronously with the beam from gun 7 to give a picture on the screen. Preferably an A.C. amplifier is used, which enables the A.C. signal to be separated from the D.C. component. The final image may be remote from the microscope and the output from 4, 5 transmitted over a radio or wire link to the reproducing tube. The scanning of 4, 5 can be sequential or with intervals between scans, and the stored charge may be reduced by only a small amount at each scan. The scanning can be relatively slow, the reproducing tube screen having a suitably long afterglow period. The storage period may be preceded by a period in which screen 4, 5 is flooded with electrons to bias it negatively while pulsing collector 6 negatively, either as described in Specification 687,270 or by increasing the current in the scanning, beam which is kept on. During the storage period, which is preferably longer than the biasing period, the scanning beam may be cut off. In a modification the scanning is effected with low velocity electrons and the screen 4, 5 operated with cathode potential stabilization; the returning electrons may pass to a multiplier from which the output is derived. In another modification the screen may be of semi-conducting or insulating material exhibiting bombardment induced conductivity. The resistance picture' is converted to a charge storage pattern by continuously or intermittently applying a diffuse electron shower to the target, which is then scanned as before. The reproducing tube may alternatively produce a photographic record. Magnetic lenses 2, 3 focus the electrons before and after passing through the object.

Title: Improvements in or relating to electric circuit breakers of the gas-blast type
IPC: H01H33/32
Filed: 1943-03-31
Abstract: 562,941. Gas-blast switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 31, 1943, No. 5176. Convention date, March 31, 1942. [Class 38 (v)] A gas-blast circuit-breaker has a circuitinterrupting structure including the areextinguishing chamber supported on a hollow insulating member into which the movable contact is withdrawn from the fixed contact in the structure after arc-extinction, so as to insert a safe enclosed disconnecting gap in circuit, the gas.blast being directed through the passage in the hollow insulator and around the movable contact and into the extinguishing chamber. Each pole of a three-pole breaker comprises an arc-extinguishing structure 23 of the radial-blast type as disclosed in Specification 553,714, the structure being mounted on a hollow insulator 21. into which the hollow movable contact 31 is withdrawn, after areextinction, in the manner of a disconnect switch. Insulator 21 is mounted on a metal casing 19 on three insulators 13, 15, 17 containing, respectively, the blast-conduit, and opening and closing air conduits, the former merging into a passage 63 in a metal casting 57 in the case 19. The casting 57 includes a cylinder in which the contact-carrying piston 53 is guided, and a twisted square-section rod 87 engages a hole in the piston so as to be rotatable by the latter to operate an auxiliary switch (not shown) through the intermediary of linkage 97, 99. The operation of each contact 31 is controlled by a double-acting valve 103 under control of an opening valve 59 and closing valve 61, preferably of the character described in Specification 552,608. Valve 103 comprises a pair of pistons 147 on a rod 109 controlling inlet ports 117, 135 and exhaust ports 127, 137 for both directions of movement. Thus, when opening air is admitted to the upper piston by way of pipes 119, 121 from opening valve 59, the rod 109 is moved down to open inlet port 117 and close exhaust port 127, and at the same time the lower piston closes inlet port 135 and opens the exhaust port 137 to exhaust the cylinder in advance of the piston. The movement of the rod 109 is cushioned by a spring 153 surrounding a sleeve 149 and abutting against washers 151, the overall length of sleeve and washer being less than the space between the sections 105, 107 of the valve-body. The solenoids 83 controlling the pilot valve of the blast valve 73 are energized simultaneously with the solenoid 159 controlling the opening valve 59 and, if desired, also with the solenoid 165 of the closing valve 61, and preferably an interlock (not shown) prevents operation of the opening valve if the blast valves fail to operate. The opening piston of valve 103 may be larger than the closing piston so as to take precedence in case of conflicting controls, 'Fig. 5 (not shown). Specification 563,040 also is referred to.
