Title: Burner apparatus
IPC: F23N5/20
Filed: 1972-09-22
Abstract: 1374015 Burner controllers COMPAGNIE ELECTRO-MECANIQUE 22 Sept 1972 [22 Sept 1971] 43942/72 Heading F4T A burner controller for a gaseous or liquid fuel burner comprises, an electric fuel valve EV, a single phase A.C. motor M driving a fan for combustion air, and also a fuel pump in the case of liquid fuel, and having a main winding E 1 and an auxiliary starting winding E21, E22 inductively coupled to winding E1 so that during normal running the voltage induced in winding E21, E22 from winding E1 maintains the valve EV in an open condition. Power is supplied to the controller via a switch LS, such as a safety thermostat, and via an ambience thermostat and/or a boiler thermostat TH. A flame detector CP comprises a photo-resistor and on start-up has a high resistance so that an amplifier A, powered from winding E1, energizes relay RF to switch contacts RFC so that winding E1 is in parallel with winding E21, E22 to start the motor M and produce ignition sparks by means of a transformer TA, valve EV being initially energized via a heater resistor EC RTS 2 of a safety relay R5 and a negative-temperature-coefficient resistor NTC but initially remaining closed for a pre-scavenging period during which air only is supplied to the burner. Resistor NTC eventually heats sufficiently to pass a current large enough to open valve EV. If no flame appears at the end of a preset period starting when valve EV opens, heater EC RTS 1, EC RTS 2 trip relay R5 to operate an alarm 5. If a flame is detected relay RF reverts to the position shown in Fig. 1, following a preset delay, EC RTS 2 being shorted out, and valve EV is supplied by windings E1, E21-E22 acting as a transformer, the current through the secondary E21-E22 of which is insufficient to cover transformer TA to give sparks. If following start-up relay RF is not energized, no power is supplied directly to starter winding E21-E22 and the current through winding E 1 of stalled motor M is large enough to cause heater EC RT S1 alone to actuate safety relay R5. A glow-coil igniter may be used in place of the spark igniter in some circuits. The flame detector CP is initially of high resistance causing condenser C2, Fig. 4, to charge up and the single transistor T in amplifier A to conduct and energize relay RF. Following flame detection CP is of low resistance but transistor T does not cut off to de-energize relay RF until a predetermined period of discharge of condenser C2 through resistors R4, R5 has elapsed.

Abstract: 1,055,580. Transit-time tubes. WESTERN ELECTRIC CO. Inc. Nov. 7, 1963 [Nov. 19, 1962], No. 43949/63. Heading H1D. The slow wave structure of an O- or M-type oscillator or amplifier is in the form of a serpentine-shaped dual conductor transmission line, e.g. a coaxial cable, having conductive vanes attached to one of the conductors at periodic spatial intervals, such vane extending through an opening in the second conductor to a point in proximity to the electron stream path. The coaxial cable delay line 14 of a crossed-field forward wave amplifier, Figs. and 2, is folded into serpentine shape and formed into a cylinder surrounding, and maintained at a positive potential with respect to, a cylindrical cathode 12. An axial magnetic field is provided by polepieces 15 and 16, connected by the soft iron envelope 17, and a conductive vane 21 projects from the inner coaxial conductor 19, at the centre of each reach of the serpentine, through a corresponding slot in the outer conductor 21, to couple with the electron stream moving round the cathode. To facilitate cooling, the inner conductor 19 may be connected to the outer conductor 20 at each end of each reach (Fig. 7, not shown), to provide a heat sink, adjacent reaches being coupled by apertures in the outer conductor, or by quarter wavelength stubs (Fig. 9, not shown). Additional cooling may be obtained by using a hollow inner conductor 19 through which coolant is pumped (Fig. 8, not shown). In a linear crossed-field backward wave oscillator, Fig. 10, the electron stream passes from cathode 37 past the plane, coaxial cable. slow-wave structure 35, to collector 38, through the magnetic field B and an electrostatic field maintained between the slow-wave structure and the electrode 36. Effective backward wave coupling is introduced by the provision of additional vanes 44 attached to the outer coaxial conductor 41 between each pair of adjacent reaches of the serpentine. Construction in a circular form, as in Fig. 7, is also referred to. In the forward wave amplifier of Fig. 11, an electron stream passing from cathode 46 to collector 47 is focused by a parallel magnetic field B, and passes through apertures 52 formed in the vane of 51. The addition of interposing vanes as 44 of Fig. 10, would produce a backward wave device. In an alternative form of the construction of Fig. 11, the serpentine slow wave structure could be wound helically around the electron stream.

Title: Improvements in magnetic material
IPC: H01F1/06
Filed: 1962-11-28
Abstract: A process of preparing fine particles of a magnetic material comprises electrolytically depositing the particles from an electrolyte having ions of iron, cobalt, nickel or their alloys into a liquid metal cathode while maintaining the liquid interface quiescent, as in Specification 815,919, and progressively lowering the cathode current density during part of the process so as to obtain particles having a constant coercivity.  With deposition at constant current, as in the above mentioned Specification, the particles' structure, and hence their coercivity, varies with time. Graphs are given indicating how the current density should be varied to give particles of constant coercivity, Fig. 1 (not shown) and to give a constant packing fraction, Fig. 2 (not shown); the two graphs are of similar form.  Purification of the electrolyte by activated charcoal which also absorbs hydrogen bubbles improves the product by preventing microscopic variations of current density at the interface.  The cathode is preferably mercury, and the electrolyte an acidic solution of salts of the ferromagnetic metals. The anode may be platinum, graphite or a ferromagnetic metal or alloy. Tables are given of suitable constituents, current densities and properties of the resulting particles.  The particles are removed as a mercury slurry, heated, treated and coated with tin or antimony as in Specification 906,718. A lead matrix may be added as in Specification 906,717 and the mercury removed by vacuum distillation. After aligning by a magnetic field the particles may be compressed in a mould.

Abstract: 1,207,020. Disconnecting components of composite foods. R. J. REYNOLDS TOBACCO CO. 27 Sept., 1968 [31 Oct., 1967], No. 46137/68. Heading A2U. Apparatus for disconnecting the components of composite food pieces, particularly to strip the fleshy parts from bony pieces of chicken, comprises a disc 16 having an array of upwardly projecting, radially extending ribs 16a, 16b, which is rotated beneath a series of tine mounts 20 extending from near the centre of the disc to near the periphery thereof to form spirals part way around the axis of the disc, the tine mounts comprising mount bars having depending tines secured in them, the lower ends of the tines being spaced from the ribs on the disc. The mount bars are detachably mounted by pins at each end engaging in apertures in brackets carried by inner and outer support rings 40, 42 which, in turn, are carried via brackets 40b, 42b on radial rods 50 which are secured at an adjustable height in collar portions 54 of fixed brackets 52 by set screws 56. This height is adjusted to give a desired minimum spacing between the tines and the ribs adjacent the periphery of the disc, a peg and multi-aperture connection between the ring 40 and the brackets 40b providing an additional adjustment for the tines nearer the centre of the disc so that the spacing between the tines and the ribs increases towards the disc centre. The tines are bent slightly from the vertical in a circumferential direction (Fig. 5, not shown) which is such that when the disc is rotated anticlockwise the tines can flex away from the disc. Pieces of chicken are fed on to the central portion of the disc and are moved radially outwardly, guided by the ribs 16a, 16b, until they are engaged by the tines which strip the flesh from the bones. The disconnected parts of the chicken pieces then either pass immediately through the gaps between the tines or are brought back towards the centre of the disc by the spiral formation of the tine mounts until they reach a position where the tine-rib spacing has increased sufficiently for them to pass through the tines. The parts are thus successively reduced in size by the tines of successive tine mounts and are eventually discharged from the periphery of the disc on to a discharge channel 12 which slopes downwardly towards a discharge shoot 4. [Specification 1,164,915 is referred to].
