Title: Method of Manufacturing Insulated Bus Bar.
IPC: H01B13/00
Filed: 1967-03-28
Abstract: 1,159,075. Insulated bus-bars. FURUKAWA DENKI KOGYO K.K. 28 March, 1967 [26 March, 1966; 10 Aug., 1966; 26 Sept., 1966, 9 Nov., 1966; 17 Feb., 1967; 18 Feb., 1967], No. 14071/67. Heading H1A. A method of manufacturing an insulated busbar comprises covering the outer periphery of a hollow conductor with insulating material and compressing the assembly thus formed into a flattened form. As shown in Fig. 2, a hollow cylindrical, non-ferrous conductor 1 passes through an extruding machine 2 and is covered with plastics insulation 3, which is then cooled in water tank 4. The assembly is then passed through a forming machine 5 and compressed into the form shown in Fig. 3, having a small flat gap A between the inner faces of the conductor. The conductor 1 may be provided on the inner wall surface with a removable agent (9, Fig. 4, not shown) or insulating tape (10, Fig. 5, not shown) to provide gap A on compression. The insulation 3 may be wound tape and may be covered with a metal sheath (12, Fig. 7, not shown), a metal-covering machine (11) and cooling tank (13) being arranged successively between cooling tank 4 and forming machine 5, for applying this sheath (Fig. 6, not shown). In another embodiment (Figs. 8, 9, not shown) a cylindrical conductor (15) is fitted coaxially into conductor 1, before or after insulation 3 is applied, and the whole assembly is compressed to provide an inner conductor of increased cross-sectional area for bus-bars of greater current carrying capacity. In a further embodiment (Fig. 10, not shown) the insulated conductor 1 is compressed into elliptical form, a flat plate (15<SP>11</SP>) inserted and the whole assembly compressed into its final flat form. Gaps between conductor 1 and insulation 3 after compression may be removed by passing the bus-bar through a high frequency induction heater (18, Fig. 12, not shown) or other heating means to soften the insulation, which contracts around the conductor when the bus-bar is subsequently cooled. Terminal machining operations such as cutting, hole punching and bending may be performed on ends of the bus-bar.

Abstract: 725,051. Automatic frequency-control systems. HAZELTINE CORPORATION. May 20, 1953 [June 14, 1952], No. 14182/53. Class 38 (4). [Also in Group XL (c)] A multi-grid tube, operating as self-oscillator and as frequency-converter for an input oscillation, is also arranged to operate as a frequency controller for maintaining the output or beatfrequency at a predetermined value. In Fig. 1, the system is applied to the sound channel of a television receiver. The sound I.F. is selected from the I.F. output stage 14 and is fed to the outer control grid 40 of a hexode tube 36, of which the cathode, inner control grid and screen are associated in backcoupling relation with a tuned circuit 49 to form a local oscillator. This circuit 49 is coupled to a coil 92 tuned to the same frequency (e.g. by stray capacity 93) and damped by a resistor 94. The coil 92 connected in the anode circuit of the tube 36 supplied a quadrature-phase component to the tuned circuit 49 and so affects the oscillation frequency. An output circuit 96 tuned to the beat frequency is also connected in the anode circuit and feeds an amplifier 19 whose output is coupled to a known frequency discriminator 20. The discriminator output is fed through a de-emphasizing resistor 123 and condenser 124 to the input of an audio signal amplifier 31. An A.F.C. signal is also taken across the condenser 124 and through an integrating network 130, 131 to the outer control grid of the hexode tube 36, thereby adjusting the oscillator frequency to bring the beat frequency into agreement with the tuned frequency of the discriminator 20. The detector stage 15 for the television signals is followed by the components normally used in television reception. The Specification also describes (Fig. 2, not shown) a circuit substantially identical with Fig. 6 of Specification 657,329, [Group XL (c)], but employing an integrating network such as 130, 131, Fig. 1, for preventing feedback of the audio signal.
