Title: Improvements in and relating to insulating joints for cable sheaths
IPC: H02G15/013
Filed: 1928-02-10
Abstract: 285,902. British Thomson-Houston Co., Ltd., (Assignees of Eby, E. de W.). Feb. 25,1927, [Convention date]. Cable joints.-To prevent the building up of excessive induced voltage, particularly in high tension cables, the lead sheath of an underground cable is broken by insulating joints which may be associated with the cable joints and, for oilfilled cables, are made impervious to oil. The joint comprises an insulating body 6, impervious to oil, such as impregnated, compressed canvas, and formed with ribs, as shown. A gasket 7 is pressed against each side of the body 6 by a twopiece metallic holder 8 which is spread over on the body 6 so as to leave a gap 9 between the two pieces of the holder 8. To prevent concentration of electric stresses at rough metal points where the sheath 5 has been cut, a thin copper band 14 is placed between the sheath 5 and the paper insulation 4 of the cable, the band 14 covering half the cut-away part of the sheath 5. A cambric tape 15 is then wound over the band 14, and a copper band 16 is placed between the lead sheath and the insulation 4 on the other side of the joint so as to lie on the tape 15. Cambric tape 17 is then wound on the band 16. The joint is then placed in position, and the cylindrical flanges 10 of the holder 8 are connected to the lead sheath 5 of the cable by wiped soldered joints 11. Tape 18 is then applied to the grooved part of the holder 8 which is first coated with asphaltum. When the joint is combined with a cable joint, the casing of the cable joint is used to support the insulating body 6, in place of the holder 8.

Filed: 1961-05-09
Abstract: 982,397. Ice-making. A. J. ROSS. May 9, 1961, No. 4253/64. Divided out of 982,396. Heading F4H. In an ice-making device comprising a tubular chilling wall, an ice-removing device and a motor for rotating the ice-removing device, either the latter is resiliently displaceable relative to the motor to enable it to slide axially of the wall or is rigidly attached to the motor which is resiliently mounted again to permit such axial movement. As shown in Fig. 4 the freezing apparatus comprises an internal evaporator 361, a resilient helical scraper 373 and a water jacket 362, the scraper being driven by a motor 379 resiliently mounted on the jacket 362 by a spring 385. In operation the scraper functions in the same manner as that in Specification 883,026, the upward force on the ice being increased, in this case, by the spring 385. In the embodiment of Fig. 6, the water jacket 422 is refrigerated by an external coil 421 and contains a rigid scraper 426 having a helical rib 427a, the scraper being driven by a motor 428 mounted on a spring 436. In operation the scraper is forced downwardly on engaging the ice and the spring 436 exerts an upward force sufficient eventually to break the bond between the ice and the jacket 422. The apparatus may comprise both an internal evaporator and an external cooling coil (Fig. 5, not shown), in which case ice forms on both the evaporator and jacket, and the motor and internal evaporator may each be secured to the water-jacket by resilient diaphragms. In the embodiment of Fig. 7 (not shown), the helical scraper is rigidly attached to a shaft which includes a pulley driven by a motor and is resiliently mounted on the device, the latter being arranged with its axis horizontal. In each embodiment the evaporator forms part of the refrigeration system described in Specification 982,396 (Figs. 1 to 3, not shown).

Title: Improvements relating to frequency modulated oscillators
IPC: G01R29/06
Filed: 1941-03-31
Abstract: 548,269. Frequency modulation. COSSOR, Ltd., A. C., and BELL, D. A. March 31, 1941, No. 4312. [Class 40 (v)] In a frequency-modulated oscillator using a thermionic reactance as the modulating element, the depth of modulation is indicated by measuring the peak value of the radio-frequency current in the anode circuit of the reactance valve. As shown in Fig. 1, the tuned circuit L1 C1 of the generator valve V, is shunted by a thermionic reactance valve V2 the inner grid of which receives quadrature carrier voltage from the circuit R, C, Cg and signal voltage from the terminals A, A2. A peak rectifier coupled to the anode circuit of the valve V2 includes a current meter M2 which may be calibrated to indicate the degree of frequency modulation. A second meter M, in the grid leak circuit of the oscillator indicates the oscillatory voltage developed across the circuit L1 C1. The ratio of the indications of the meters M1 M2 may be measured by substituting for these meters a differential meter with separate coils traversed by the respective currents (Fig. 2 not shown). In another arrangement, Fig. 3, a cathode-ray tube O is used to indicate percentage frequency change. The plates P1 P2 receive oscillatory voltages proportional to the oscillatory anode current of the valve V2, and the plates P3 P4 voltages proportional to the current in the oscillatory circuit L1 C1. The inclination of the screen trace indicates percentage frequency change or depth of modulation independently of changes of the operating wavelength by variation of L1 C1. In Fig. 4, two reactance valves V2 V21 are used with the quadrature voltages applied to their grids in opposite senses from the circuit L, C1, and with the signal voltages from A1 A2 also applied thereto in phase opposition. Meters M4 M41 measure the radio frequency current in the respective anode circuits of the valves V2 V21, and indicate the peak modulation in the upward and downward direction respectively. The modulator may thus be balanced by adjusting the screen grid potential of one of the valves.

Title: Improvements in or relating to process for recovery of cresylic acids
IPC: C07C37/00
Filed: 1956-02-15
Abstract: Cresylic acids, e.g. phenol, cresols and xylenols, are recovered from an aqueous solution derived by contacting petroleum distillates with aqueous caustic alkali, by adjusting the pH of said solution to above 11 and below 12, then contacting said solution with dialkyl ether having from 2 to 6 carbon atoms in each alkyl group under liquid phase conditions, separating a liquid ether phase and recovering cresylic acids therefrom. Cracked or virgin petroleum distillates may be used boiling in the gasoline range, such as sour catalytically cracked naphtha, or in the range 350-600 DEG  C.  The caustic alkali specified is caustic soda.  The pH is adjusted by adding acid or acid-reacting material such as sulphuric acid or carbon dioxide. Dialkyl ethers mentioned are diethyl, diisopropyl, ethylisopropyl and dibutyl ethers.  The ether contacting may be continuous and countercurrent and conducted in a packed or perforated plate tower, at temperatures between 60 DEG  and 100 DEG  F.  Cresylic acids are recovered from the ether solution by distillation.  In examples, aqueous solutions obtained by extraction of sour catalytically cracked heavy naphtha with caustic soda solution are extracted at pH's of from 11 to 14 with diethyl ether to obtain cresylic acids, and the use of benzene, iso-octane and cyclohexane in place of diethyl ether is described by way of comparison.
