Title: Carburetor
IPC: F02M21/02
Filed: 1955-07-08
Abstract: 778,889. Mixing air and gas. BENDIX AVIATION CORPORATION. July 8, 1955 [Aug. 23, 1954], No. 19866/55. Class 7 (2). In a carburetter for use with gaseous fuels, comprising a metering control for supplying fuel to the induction passage, having a fuel inlet passage and a restriction in this passage and an idle system, the system includes a conduit intersecting the fuel inlet passage within the restriction and communicating with the induction passage. Butane or propane gas or other gaseous fuels may be used. The gaseous fuel from a regulator enters a passage 20. It can pass by way of a main jet 22 a passage 16 and annular chamber 12 to the induction passage. The fuel can also pass through a passage 40 which operates in parallel with the main supply. When the manifold vacuum reaches a desired low value the suction acting on the diaphragm 36 becomes inadequate to hold the valve 30 closed and an enrichment is obtained. Under idling conditions the gaseous fuel flows from passage 20 through passages 28, 26 and main jet 22 into the idle passage 46 which leads to the passage 56 (Fig. 2). The fuel passes to a chamber 58 where it is mixed with air prior to being discharged through a passage 68. A reverse flow of air is sucked through the orifices 19 and causes dilution of the idle supply.

Patent GB-977417-A (GB)
Title: Transverse-mode electron discharge device and method of operating same
IPC: H01J25/78
Filed: 1961-06-06
Abstract: 977,417. Electron beam parametric amplifiers; travelling wave tubes. ZENITH RADIO CORPORATION. June 6, 1961 [June 9, 1960], No. 20360/61. Heading H1D. The noise level associated with the cyclotron wave mode in a transverse-field electron discharge device, e.g. a parametric amplifier or travelling wave tube, is reduced by providing in the immediate vicinity of the cathode a longitudinally magnetic field having a strength several times greater than that normally provided for coupling electromagnetic signal waves to the beam. The cyclotron resonance frequency in the immediate vicinity of the cathode may thus be several times greater than the signal frequency, and the magnetic field strength may be reduced gradually in intensity in the downstream direction to a minimum value, producing a cyclotron resonance frequency which may still be higher than the signal frequency or equal to the signal frequency. As shown, Fig. 1 (which shows diagrammatically on the gun and first coupler of a parametric amplifier), a magnetic field H is provided throughout the length of the device, and has a strength such that the associated cyclotron frequency is substantially higher than the signal frequency in the region of the coupler 30; to enable interaction to take place between the beam and the signal wave an interdigited coupler is used. Alternatively, a stronger magnetic field may be provided in the vicinity of the cathode only by using a permanent magnet situated behind the cathode, a polepiece of cobalt being provided behind a convex cathode emitter and the coupler being in the form of a balanced helical transmission line having two helices disposed on either side of the beam path, Fig. 2 (not shown), or a field concentrator disposed behind the cathode emitter with a coupler in the form of a pair of deflectors disposed on opposite sides of the beam path, Fig. 3 (not shown). The invention may be applied to a parametric amplifier having the normal type of quadrupole modulation expander which develops a time variable non- homogeneous pumping field. A travelling wave tube, Fig. 8, has a high magnetic field provided in the vicinity of the cathode 11 by a polepiece 41 and a delay line formed by two helices 311, 32<SP>1</SP>.An input signal source 81 is coupled to the delay circuit and an amplified output is obtained in a load circuit 82 when the phase velocity of the signal wave on the helices is synchronous with the phase velocity of the slow synchronous wave on the electron beam. The device may alternatively be a backward wave amplifier.
Patent GB-925671-A (GB)
Title: Improvements in taping machines
IPC: B65B7/28
Filed: 1958-06-25
Abstract: 925,671. Applying adhesive tape. COW & GATE Ltd., and G. K. CHARLES. June 25, 1959 [June 25, 1958], No. 20452/58. Class 73. A tabbing device for a taping machine which applies tape 3 from a spool 4 around a container (not shown), comprises a guide-surface 2 arranged to engage the non-adhesive face of the tape to guide it through the device towards the container, means 12 to press a free end of a continuous length of tab-tape stored on a spool 14 against a part of the adhesive face of the tape on the guide surface 2, the pressure means 12 and the guide surface 2 being separable from one another to release pressure between the tab-tape and the adhesive tape, the arrangement being such that separation of the means 12 from the surface 2 also effects cutting engagement between severing means 10 and the tab-tape to sever the part of it adhering to the adhesive tape whereby the adhesive tape with a tab is applied to the container. The surface 2 is part of a rubber roller rotatable about a spindle 11 on a triangular member 6 which is pivoted at 5 to the baseplate 1 of the device to which the pressureroller 12 is also pivoted at 16. The tab-tape is held on to the roller 12 by a spring 15. An arm 17, spring-loaded at 21, is pivoted to the underside of the plate 1 at 18 and has a lateral extension 19 which protrudes up through an arcuate slot 20. With the taping machine at rest the extension 19 is held by the spring 21 against the left-hand end of the slot 20 (Fig. 1), where, by pressing against the guide surface of roller 2, it holds the adhesive tape on the latter against the tab-tape on the presser roller 12. On application, movement of the tape 3 in the direction of the arrows rotates the roller 2 which frictionally causes the extension 19 to move to the other end of the slot 20 against the spring 21. The tension in the tape causes the member 6 to pivot away from the pressure roller 12, disengaging the adhesive tape from the latter and bringing up the knife 10 to cut-off the end of the tab-tape. As long as the application of the tape continues, a cam-surface 7 on the member 6 holds the extension 19 at the right-hand end of the slot 20. On removal of the tension from the adhesive tape 3 the extension returns to the other end of the slot. Fig. 3 shows another embodiment in which the guide-surface roller pivot 23 is fixed whilst the pressure-roller 28, carrying tab-tape 13 is on an arm pivoted at 25 and is moved into and out of contact with the adhesive tape on the guide roller 23 against a spring 34 by a solenoid 33. A knife 35 is fixed in a position where it will sever the adhered end of the tab-tape when the roller 28 is released from the roller 22. The solenoid is actuated at the correct instant by photo-cells operated by registration marks on the tape (not shown). Movement of the roller 28 by pneumatic or mechanical means is also claimed. Specification 574,156 is referred to.

Title: Improvements in or relating to apparatus for determining the quantity of charged particles of predetermined mass present in a space
IPC: H01J49/38
Filed: 1959-06-15
Abstract: 898,919. Mass spectrometers. FERNSEH G.m.b.H. June 15, 1959 [June 13, 1958; Nov. 24, 1958], No. 20464/59. Class 39(1). A mass spectrometer comprises two terminal electrodes 2, 3, Fig. 1, and at least three intermediate focusing electrodes 4 to 12 energized as shown. With an alternating voltage of suitable frequency applied to electrodes 4 and 12, ions oscillate in the space within the electrodes 4 to 12 about the central plane and selected ions reach the end electrode 3 to give an indication on the meter 21. Ions passing through points in a surface in proximity to one terminal electrode are electron-optically imaged in corresponding points in a surface in proximity to the other terminal electrode. The ions are created by electrons which are emitted from a filament 16 and oscillate about a grid 15 forming the end wall of terminal electrode 2. Ions generated on the filament side of grid 15 are collected by electrode 18. Some of the intermediate electrodes may be mesh grids or spirals or rings of wire. In a modification, Fig. 2 (not shown) the ions are created by electron beams injected through the terminal electrodes 2 and 3. The ions may be collected by an electrode beyond the terminal electrode 3, this electrode having an electron permeable end wall to allow passage of the ions. The ions may pass to an electron multiplier. Sensitivity and resolution may be improved by modulating the intensity of the ion-generating electron stream in synchronism with the oscillation of the ions. The electron stream may be pulsed. Alternating voltages of different phase may be applied to the electrodes. In the embodiment of Fig. 5, the electron stream from cathode 101 is deflected laterally to strike a body 118 whose surface is to be analysed. Electrode 106 is the signal electrode and by modulating the electron beam emitted from cathode 101 a distinct signal is obtained for each mass present. In the embodiment of Fig. 6, the electrodes are so shaped that not only the ions are focused, but the electron beam from gun 123 is focused to a high intensity spot on the body 126.

Patent GB-586957-A (GB)
Title: Improvements in or relating to three colour cameras
IPC: G03B33/00
Filed: 1943-12-14
Abstract: 586,957. Optical systems; colour photography. COOTE, J. H. Dec. 14, 1943, No. 20937. [Classes 97 (i) and 98 (ii)] In an optical dividing system for tricolour separation, of the kind comprising two inclined metallised transmitting-reflectors, the metals deposited on the reflectors are different, and at least one exhibits spectral selection in the transmitted and reflected beams. As shown, the beam from the lens 1 of a tricolour camera falls upon a metallised reflector 2 which reflects a portion of the beam containing at least 50 per cent blue light to a blue-sensitive layer 3, and transmits a high proportion of red and green light to a second metallised reflector 4 which reflects a portion containing at least 50 per cent red light to a red-sensitive layer 5, the remaining mainly green light passing through the reflector 4 to a green-sensitive layer 6. Colour filters 13, 15, 16 are associated with the various sensitive layers. The reflectors may be enclosed in an all-glass or transparent plastic material prism block system extending from lens 1 to the planes of the filters. The metal of reflector 2 may be Al, Be or Ag, and that of reflector 4 Au, Cu or Zn, and may be deposited, by thermal, evaporation or cathodic sputtering in a high vacuum, upon the optically-flat surface of a transparent pellicle as of gelatin or cellulose nitrate, or upon optically - flat glass or transparent plastic material such as polymethyl methacrylate in plate or prism form. When only one of the reflectors exhibits spectral selection, the other, exhibiting high and uniform spectral reflection, may be a metal of Group VIII of the Periodic System; thus, the metal of 2 may be rhodium, and that of 4 gold. Interchange of the positions of the reflectors is possible if the composition of the incident light renders this desirable. The reflectors are preferably inclined at angles greater than 45 degrees to the lens axis, e.g. at 50 and 60 degrees respectively. For daylight work with fast panchromatic films and filters all having factors of from 5 to 6, surface 2 should reflect about 30 per cent of the light incident upon it, and surface 4 about 48 per cent. Further forms of the system are described in which (a) the reflectors consist of opticallyflat glasses meeting along a line intersecting the optical axis of the lens 1, with appropriate compensation (e.g. varying thickness of colour filters) for the differences in the lengths of the paths of the divided beams, and (b) the reflectors are formed on the internal surfaces of a compound prism block made up, e.g. of four similar glass or plastic material prisms of right-angled isosceles form cemented together with their refracting edges in contact, and in this form the colour filters may be in the prism block behind the metallised surfaces. Specifications 440,006 and 475,415 are referred to.
