Filed: 1967-06-02
Abstract: 1,156,750. Transformers. SUPERIOR ELECTRIC CO. 2 June, 1967 [15 July, 1966], No. 25553/67. Addition to 1,022,780. Heading H1T. A winding e.g. for an auto-transformer, is provided with a commutating surface 22 which is contacted by a movable brush, the surface 22 being formed by a method comprising the steps of: (a) winding spaced turns of an insulated conductor 14 about a core e.g. a toroid, (b) depositing a coating of e.g. epoxy resin, on the surface of the coil which is to be contacted by the brush, (c) exerting pressure on the parts of the turns previously coated, while the coating is still semi-liquid, to force the coating material off these parts and into the adjacent interstices, (d) removing e.g. by grinding, the insulation and some of the conductor of these turns to form bared surfaces 26, and (e) depositing a good conductor e.g. gold, silver, rhodium, on the bared surfaces. The conductor 14 may be of copper and the core may be magnetic and comprise spirally wound strip metal. The epoxy coating may be applied by dipping the heated coil into epoxy powder which melts and coalesces on the coil, and the pressure may be applied by a resilient member e.g. of silicone rubber. During pressurizing the coil may be dipped in a cooling bath e.g. water, to solidify the epoxy material. The coating is forced into the interstices such that its level will be below that of the surface of the subsequently ground away conductor, and the inner and outer peripheral edges of the coil may be formed with thicker rims of the coating material (Figs. 8 and 9, not shown). The commutating surface may be formed on a raised part (21) (Fig. 1, not shown), of the surface of the coil.

Title: Improvements in methods of, and means for, stabilizing or determining microwave frequencies
IPC: H03L7/26
Filed: 1948-10-01
Abstract: 658,198. Automatic frequency control systems. RADIO CORPORATION OF AMERICA. Oct. 1, 1948, No. 25646. Convention date, Jan. 27. [Class 38 (iv)] [Also in Group XXXVI] The frequency of a generator 10 is stabilized or determined by means which produce two trains of pulses, the phase or time difference of one train being dependent on a microwave absorption line of a gas, and that of the second train being dependent on the beat frequency between generator 10 and a controlling generator, phase differences between the two trains operating stabilizing or indicating means. As shown, a frequency modulated oscillator 16 sweeps a range of frequencies including an absorption frequency of gas in a cell 14, and opposed rectifiers 18 and 27 supply pulses to an amplifier 25. A wave-guide bridge system 20 in conjunction with a rectifier 19 and filter 13 produces a train of pulses in response to a specific beat frequency between generators 10 and 16. The two trains of pulses are carried to a rectifier bridge 34 and produce in its output a voltage proportional to the deviation of generator 10 from the frequency standard of the gas cell, which can be utilized for control or indication. The circuit 34 can be replaced by the known flip-flop type of circuit. Specifications 640,848, [Group XXXVI], and 653,979 are referred to. Reference has been directed by the Comptroller to Specification 663,065.

Title: Process for the production of refractory materials
IPC: C04B41/50
Filed: 1961-07-14
Abstract: Refractory materials are produced by a process wherein the raw refractory material is charged with carbon to obtain an electrically conductive mixture by forming carbon in situ by impregnation with and subsequent decomposition of a hydrocarbon, the mixture thus obtained then being sintered by electrical heating. In examples (1) dolomite and magnesium carbonate are sintered to yield the oxides which are impregnated with tar and heated to 800 DEG  C. to decompose the tar, the carbonaceous mixture then being heated to 2000 DEG  C. by electrical resistance heating in a neutral atmosphere.  (2) Magnesia is mixed with 6% tar and 4% carbon, pelletized and heated to 800 DEG C. to form the carbon followed by electrical heating as in (1).  In Example (3) the heating at 800 DEG  C. is at 30 atmospheres. Vibration and compression may be used during or after the sintering to consolidate the products.
