Title: Electrically operated liquid feed pump
IPC: H02K5/132
Filed: 1972-07-12
Abstract: 1373599 Circumferential-flow pumps COMPAGNIA ITALIANA TUBI METALLICI FLESSIBILI SpA 12 July 1972 [12 July 1971 30 Sept 1971] 32521/72 Heading F1C [Also in Division H2] In an electrically operated pump comprising a commutator electric motor and adapted to be immersed in an inflammable fluid to be pumped, the motor rotor is mounted on a shaft passing through end-walls of a casing, leaving between the shaft and the end-walls, annular spaces so dimensioned as to form flame barriers. The pump shown is intended to be mounted in a vehicle fuel tank and comprises an impeller 8 mounted on the shaft 7 of D. C. motor 2. Annular spaces 20, 21 are formed where shaft portions 9, 10 pass through bores 17, 19 in members 15, 18 secured to casing 3. The ratio of the difference between bore and shaft diameters to the length of the annular spaces is between 0.01 and 0À05 and the length of the spaces is at least 4 mm. The, annular spaces communicate with the casing interior through channels 16, Figs. 2-4 (not shown) cut in bearing seats 13, 14, or in the bearing bushings 11, 12 themselves. In the event of an explosion inside the casing 3, the annular spaces prevent flames reaching the outside of the casing but allow high-  pressure gases to escape. In addition, the annular spaces provide access to the motor for a small flow of fuel sufficient to remove graphite particles from the commutator 4. A hole 23a communicating with the high pressure outlet 26 of the pump may be provided for this purpose. Alternatively, a hole may be formed in member 15 for inter-connecting the pump outlet 26 and the motor casing interior. This hole must then be of such dimensions as to prevent the propagation of flames to the casing exterior. Yet again, the casing interior may be put in communication with the low-pressure pump inlet 24 so that the fuel inside the motor casing flows in the opposite direction.

IPC: H01F19/00
Filed: 1956-10-25
Abstract: 823,421. Transformers. STANDARD TELEPHONES & CABLES Ltd. Oct. 25, 1956, No. 32588/56. Class 38 (2). A high-frequency transformer comprises a ferrite core 5, a spirally wound inner winding 6 of conductive tape and a helically wound outer winding 8 of wire, the winding 6 being fed through terminals 34 and being provided with a half-turn extension 3-7 which forms an electrostatic screen, the terminal 3 being earthed. Points 7 and 9 have equal but opposite potentials with respect to earth so that the capacity couplings between the portion 3-7 of the winding 6 and the winding 8 and the portion 3-9 and the winding 8 cancel each other out and the transformer therefore behaves as though an earthed screen were interposed between the windings. Specification 658,348 is referred to.

Title: Improvements in detecting and cutting out an earth in a high tension network
IPC: H02H3/16
Filed: 1925-12-24
Abstract: 253,478. Akt.-Ges. Brown, Boveri, et Cie. June 13, 1925, [Convention date]. Cut - out arrangements.-An indicating arrangement for selectively detecting in what part of a high-tension network an earth has occurred includes devices in the feeders responsive to higher harmonics of the fundamental frequency, the occurrence of which indicates the existence of an earth current. Fig. 1 shows a system in which a three-phase generator G feeds bus-bars S, T, R and has its neutral point O connected to earth through a blow-out choking-coil L. In the feeders I, II are inserted frequency meters FRI, FTI, FSI, FRII, FTII, Fsn which indicate the occurrence of higher harmonics. Condensers C corresponding to the partial capacities to earth and resistances W corresponding to the leakage resistances are connected as shown. A fault Q to earth is shown on phase T of the feeder I. The choking-coil L being tuned to resonance with the partial capacities of the network with respect to the fundamental frequency, only capacity currents Jc of this frequency will flow therethrough. The sum of the loss currents Jw and higher harmonic currents Jo flows through the fault Q to the conductor T and causes an indication of the frequency meter FTI. This may act as a relay to cut out the faulty feeder or operate a signalling device at a distance. Frequency meters having vibrating tongues may be employed, preferably connected through loosely-coupled current transformers. Fig. 3 shows an arrangement by which the effect of the fundamental frequency on the instrument is eliminated. The primary winding P of a current transformer is connected in the feeder. The current from the secondary winding Q flows through a bridge formed of equal inductances L1, L2 and resistances W1, W2. A two-coil instrument Z has one coil connected to the points U, V and the other coil to the points M, N, the values of the inductances and resistances being so chosen that for the fundamental frequency the currents in the two coils are in quadrature and no deflection occurs. For currents of higher harmonic frequency the currents in the two coils of the instrument Z are not in quadrature, owing to the change in the reactances of the bridge due to change of frequency, and a deflection ensues. Alternatively, a single-coil instrument may be connected across the terminals of the secondary winding in parallel with a circuit containing inductance and capacity tuned to the fundamental frequency. In order to locate the position of a fault in a long-feeder fed at one end, several instruments are provided at intervals along the feeder, only those being affected which lie between the bus-bars and the fault. If such instruments are used as protective relays, the time lag should be shorter the further the instrument is from the bus-bars.

Each linkage consists of links 88, 92, 98, 102 which are pivotally connected between the frames 20, 28 and nuts 84. The nuts 84 are threadably engaged on shafts (64) and move therealong when the shafts (64) rotate. In operation, the angle of the frame 28 is adjusted by moving a control knob 118 to the righthand end of a slot 122 whereby a control rod (110) moves a carriage 80 to the left causing teeth (78) on the left-hand clutch member 76 to engage teeth (62) on drive shaft (56). Then the knob 118 is raised or lowered within slot 120 so that toggle member (126) actuates a switch (124) which operates motor 50 and thereby rotates drive shaft (56) and shaft (64) in the appropriate direction to raise or lower the frame 28. The frame 20 is adjusted similarly by moving the control knob 118 in the opposite direction.
