Title: Improvements in or relating to protective systems for electrical equipment
IPC: H02H3/16
Filed: 1951-03-05
Abstract: 727,966. Protective cut-out arrangements. NALDER BROS. & THOMPSON, Ltd., SHEWAN, J. R., and ECKETT, S. W. March 21, 1952 [March 5, 1951], No. 5339/51. Class 38 (5). Normally-earthed electrical apparatus 2, e.g. a portable drill, is disconnected from supply terminals L, N by a contactor C', C', in the event of failure of the earth connection or if the apparatus winding becomes earthed. The contactor casing 1 is earthed at E and the earthed connection includes this point, a current trip coil IC, the secondary T1S of a transformer TI, an auxiliary relay CR, a pilot wire 5, the apparatus casing 2, a pilot wire 4 and the casing 1. The transformer primary TIP is connected across terminals L, N in parallel with a voltage trip coil VC through an auxiliary contact C' of the contactor, the circuit of coil VC including contacts C<SP>4</SP>, C<SP>5</SP> of relay CR. If the earth connection is interrupted, relay CR is de-energized and contacts C<SP>4</SP>, C' close to energize coil VC and open the contactor. If the apparatus winding is earthed, the excess current through coil IC opens the contactor. A non-linear impedance RI shunts the coils IC, CR and secondary TIS so that a voltage rise on the apparatus casing causes a decrease of the resistance of RI so as to delay any further voltage rise for a time, e.g. 0.05 secs., so that the contactor can open. In a modification (not shown) the winding TIP is connected between terminal L and the earth point E, the neutral N being earthed, so that if the earth at E fails, coil CR will be de-energized to open the contactor. In a further modification (not shown), the coil IC is connected between secondary TIS and the earthed neutral N, the contactor having further auxiliary contacts to control the earth circuit including the neutral conductor. According to a further arrangement, the end of coil IS is not connected directly to the earth point' E but is independently earthed elsewhere so as to include two earth points in the earth connection.

Title: Improvements in or relating to high frequency composite transmission systems and cables or conductors therefor
IPC: H04B3/00
Filed: 1930-02-19
Abstract: 349,029. Cables. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Assignees of Quarles, D. A. ; 273, Robin Road, Englewood, New Jersey, U.S.A.) Feb. 19, 1930, No. 5537. Convention date, March 30, 1929. [Class 36.] In a wired-wireless system, one side of the transmission circuit comprises a specially provided conductor or conductors, which are surrounded by a plurality of conductors in parallel forming the return side. The system may be linked to a short length of multiple cable in which case the special return lead is connected to the inner lines of the cable and the live-wires to the outer, (Fig. 7, not shown), or with longer cables it is preferable to provide a special conductor at the centre of the cable surrounded by enough insulation to sufficiently reduce its capacity relative to the other conductors (Fig. 8, not shown). When a cable of this nature becomes too long for carrier transmission a specially designed cable may be used, constructed as follows. The inner and outer conductors 110, 120, Figs. 11, 13, 14, and 16, are formed as cylinders of braided copper wire, the inner diameter of the outer being about four times the outer diameter of the inner, and the inner cylinder is supported relative to the outer by suspension cords 130 of silk, cotton, hemp, &c., arranged tangentially to the inner cylinder and braided in a continuous length into the structure of the outer. The whole structure is stiffened and waterproofed by impregnation. The cable may be supported by hooks 131, Fig. 11, from a line 132, the hooks being provided with a cradle 133. Various protective armours may be used, for instance copper tape 125, Fig. 13, may be wound on and a steel armouring 136 superposed, consisting of interlocking grooved ribbon. Alternatively a lead sheath may be used. The armoured cable may be supported by a rod 140, Figs.14 and 15, which is bent into a hook 141 arranged round the inner conductor. An insulating bush 142 over the rod 140 bears on the inner conductor, and is provided with a shoulder 144 which supports a band 145 round the outer conductor. In a third arrangement a short section of the outer conductor is removed and the inner conductor wired to an insulator 147, Fig. 16, a split insulating plug 149 being used to close the exposed end and secured by a strap 150 and set-screw 151.

Abstract: 1382823 Electrolytic reduction EXXON RESEARCH & ENG CO 25 Feb 1972 [26 Feb 1971] 5557/71 Heading C7B The viscosity index of at least part of a lubricating oil feedstock comprising reducible compounds, e.g. naphthalene, is increased by reducing the compounds in an electrolytic cell having anode and cathode with an electrolytic system (solvent and electrolyte) comprising chemically bound hydrogen in which electrons from the cathode are accepted and solvated during passage of electric current. The solvent may be liquid ammonia or alkylamine (e.g. butyl- or ethylamine) or alkyl (e.g. tetrabutyl) ammonium chloride; the electrolyte may be an alkali metal salt e.g. LiCl, NaCl, LiOH or NaOH at least partly soluble in the solvent. The chemically bound hydrogen may be replaced during or after passage of the current by protonation, e.g. at an inert porous anode to which hydrogen is supplied, or outside the cell during recirculation of the system, the protonation agent being HCl or NH 4 Cl for LiCl and water or alcohol for LiOH. Preferably the cell is divided by a porous diaphragm into anolyte and catholyte compartments, one or both of the electrodes being in the form of particles fluidized by the system and/or reducible compound. For supplying hydrogen, the fixed or fluidized anode may be of PTFE admixed with catalytic particulate metal e.g. Pb group metal or Fe, Ni, Co. The anode may also be of graphite, and the cathode of Ti gauze.

Title: Improvements in and relating to change-speed gears
IPC: F16D21/04
Filed: 1922-02-27
Abstract: 176,355. Williams, E. R. March 7, 1921, [Convention date]. Variable-speed toothed gearing of the countershaft type, suitable for motor-vehicles, is modified by the use of subsidiary gear pairs to facilitate the engagement of teeth in changing speed, the subsidiary gearing being operated by friction clutches in pairs. The countershaft 4, Fig. 2, constantly driven by a pair of wheels 5, 6 from a driving-shaft 1 carries fixed gears 9, 8, 10. A gear 11 slidable on splines on a driven shaft 3 has a clutch face 7 which is engaged with a like face 7' on the gear 5 for directdriving. For second speed, the gear 11 engages the gear 9. A second sliding gear 12 engages the gear 8 for third speed, or an idler in mesh with the gear 10 for reversed driving. Subsidiary gears 22, 23, 24, 25 corresponding respectively to these three speeds and to reversed driving are secured to an extension 21 of the shaft 4. These mesh with gears 27 - - 30 loose upon the shaft 3 and adapted to be connected thereto by friction clutches 32 - - 35 movable in pairs. If, say, the pair 8, 12 is to be intermeshed, the gear 29 is clutched to its shaft long enough to bring the speed of the teeth of the gear 12 to near equality with that of the teeth 8. After engagement, the gear 29 is declutched. Further to facilitate engagement, the shaft section 21 may be driven from the shaft 4 or from the shaft 1 through the yielding coupling 64, 65, Fig. 8. The gears 11, 12 are operated by forks'secured to telescoping -rods 13, 14, Fig. 1, which are operated from a suitable selective control through links 19, 20. The friction clutch pairs are operated in unison with the elements 11, 12 through forks 40, 41 pivoted upon fixed pins 42, Fig. 5, and articulated to telescoping rods 43, 44, Figs. 1, 3, and.4. Collars 51 secured to the rods 43, 44 are connected through springs 55 to cylinders 50, which are adapted to slide and are connected by bridge levers 48, 49 to recessed collars 46, 47 upon the main selector rods 13, 14. Springs 56 keep these bridge levers in position so that when one of the rods 13, 14 begins to move, the corresponding friction clutch is gradually brought into action. As the movement of the rod 13 or 14 nears its end, the lever 48 or 49 strikes a fixed cam 57 so as to become disengaged from the rod 13 or 14, which moves on alone to engage the main gear. The springs 55 assert themselves and the friction clutch and subsidiary gear pair are thrown out. An arrangement with the friction clutches on the counter-shaft is described, but they may be on both shafts.
