Title: Improvements in or relating to submersible electric motors
IPC: F04D13/10
Filed: 1934-03-24
Abstract: 431,886. Stuffing - box substitutes. PULSOMETER ENGINEERING CO., Ltd., and GIBBS, B. H., Nine Elms Iron Works, Reading, Berkshire. March 24, 1934, No. 9324. [Class122 (v)] A leakage - collecting chamber 3 is arranged about the shaft 5 of a submersible pump 1 driven by an electric motor 2. A labyrinth or other packing 4 is arranged between the pump and the chamber 3, and may be protected from sand by wire gauze 7. Leakage is discharged from the chamber 3 through a pipe 9, with a check valve 10, by an impeller 8 on the shaft 5. The boss 11 of the impeller is elongated and hollow, and forms a labyrinth packing with a stationary sleeve 12. Further packing 15 is arranged below the sleeve. A second leakage-collecting chamber 14 is arranged below the packing 15. The shaft 5 is surrounded by a stationary sleeve 16 in the chamber 14 and entry of leakage into the sleeve is prevented by a thrower 17 on the shaft. A float 18 in the chamber operates a bell or other signal to indicate the collection of leakage.

Title: Improvements in or relating to protective circuits
Inventor: RIDGERS CHARLES EDWARD SYDNEY
IPC: H03F1/54
Filed: 1955-03-30
Abstract: 782,596. Protective arrangements. DECCA RECORD CO., Ltd. Nov. 22, 1955 [March 30, 1955], No. 9341/55. Class 38 (4). Relates to circuits for protecting equipment embodying electronic valves in the event of flash-over in a valve such as to cause a heavy current to be drawn from the supply-source. As shown, the circuit to be protected is supplied from the secondary winding 10 of a transformer 11. When'the apparatus is switched-on initially, an alternating-current supply is applied to input terminals 22, 23, and a direct-current supply to terminals 22, 24, contacts BLC1 being positioned so that reduced voltage is provided by the winding 10. The temperature of a thermistor 18 gradually increases until, after a predetermined period, a relay RLB operates to remove a shunt resistor 19 and to short-circuit the thermistor, to ensure that the relay operates quickly. Contacts RLB2 complete a circuit for relay RLC through contacts RLA2 whereby contacts RLC1 operate to provide full output voltage from the winding 10. When a flashover takes place so that a large current is drawn through winding 13, a relay RLD is energized through transformer 14 and rectifier 15, so opening contacts RLD1 and closing contacts RLD2. Relay RLA is thus energized to open contacts RLA1 and cut-off the supply to the transformer winding 12. Contacts RLA2 are also opened to release relay RLC and changeover contacts RLC1 to the reduced-voltage position. When the supply to winding 12 has been interrupted, the relay RLD will release, so closing contacts RLD1 and restoring the supply to winding 12 whereby reduced voltage is now supplied by winding 10. The release of relay RLD will open contact RLD2, but capacitor 20 will maintain the relay RLA in its operated condition for a short period. After the relay RLA has'released, contacts RLA1 close to shunt contacts RLD1 which have already closed. Contacts RLA2 are also closed to energize relay RLC and change-over contacts RLC1 to the full-voltage position. In a modification, contacts RLC1 are connectable through alternative resistors of different values to a selected tapping in the winding 12, Fig. 2 (not shown).

Abstract: 558,708. Vitamins. NATIONAL OIL PRODUCTS CO. July 8, 1942, No. 9464. Convention date, June 18, 1941. [Class 2 (iii)] In order to remove objectionable odours and tastes from vitamin containing material of fish or animal origin, such as fish oils, fish liver oils and concentrates thereof, they are heated at 60-200‹C. with an antioxidant fraction containing vegetable oils and antioxidants prepared from vegetable oils, or plant material by the process of Specification 550,983. Preferably, they are heated in the presence of an inert gas such as carbon dioxide and under reduced pressure. In examples, antioxidants prepared by extracting wheat germ oil, corn germ oil and soya-bean oil with isopropanol are heated with shark liver oil in the presence of nitrogen and at reduced pressure. The antioxidant prepared from corn germ oil and soya-bean oil is freed from phosphatides, before use by forming a 10 per cent. solution by adding acetone, cooling to -10‹C. and removing the solvent from the acetone soluble fraction. The treated oils have improved resistance to oxidation and may be decolorized, e.g. by means of decolorizing carbon (c.f. Specification 535,014). Antioxidant fractions may be prepared from cereal oils, olive, sesame, cotton seed, palm, rice, linseed, oiticica, teaseed, perilla, alfalfa, celery seed, flax seed, ground nut, kapok, mustard seed, melon seed, tomato seed, grape seed and peach kernel oils and beans, seeds and grain from which these oils are obtained.

Abstract: 641,428. Electric discharge tubes. RADIO CORPORATION OF AMERICA. April 10, 1947, No. 9605. Convention date, April 12, 1946. [Class 39 (i)] A cathode-ray tube for use in radar comprises means for focusing and deflecting a beam from an electron gun over a target, a screen adjacent and on the gun side of the target and adapted to control the flow of secondary electrons bombarded from the target, electron multipliers on the other side of the target and extending radially beyond it and means for directing the electrons escaping from the target into the multipliers. The cathode-ray tube shown in Fig. 1 contains a wall coating 12 and a persuader cylinder 13 having an opening 15 to permit entry of the deflected electron scanning beam and into which projects a flanged end 17 on a metal pedestal 16, the flanged end 17 supporting a flanged aluminium disc 18 having a slightly convex surface anodized to form a thin coating 19 of aluminium oxide constituting the target. A fine woven mesh screen 20 conductively joined to the pedestal 16 is stretched over the coating 19. Dynodes 21, 22, 23 and 24 forming part of an electron multiplier are placed around the pedestal 16, each dynode having a plurality of slanting vanes with fine mesh screens 25 spaced from but conductively attached to the metal support of the vanes, as described in Specification 634,639. The last dynode 27 of the multiplier is a metal disc without an attached screen and a collecting screen electrode 28 is placed between the dynodes 27 and 24. A metal shield 29 is welded to the pedestal 16 and a signal wire 30 is connected to the inner unoxidized surface of the disc 18. In the construction shown in Fig. 2 an asymmetrical field is produced in front of the target to prevent return of the secondary electrons to the target by cutting out about one half of the persuader cylinder 31 and replacing it by a semi-cylindrical fine-mesh screen 32. Another semi-cylindrical screen 33 is located outside the screen 32 and makes contact with the first dynode comprising a semi-cylindrical cup 34 having an inside surface of good secondary emission properties. One half of each of the other electrodes of the electron multiplier is inactive and may be cut away.

In a pump having an impeller 12, Fig. 1, associated with one or a pair of part-annular side channels 17, the effective combined volume of the impeller chamber 11 and side channels can be varied by axial adjustment of a piston 18 and/or by angular adjustment of a member 15 containing a respective inlet for each side channel, the adjustment of the member 15 thereby controlling the effective length between the inlet and outlet of each side channel. The two inlets are fed through a common duct 16, and the two outlets extend tangentially and communicate with two outlet passages (14), Fig.2 (not shown). Means may be provided for adjusting the position of an outlet. The piston 18 is spring-biased to the maximum volume position and is adjustable by fluid-pressure or other means to a position in which it completely fills the side channels.

Pins 1, 2, 4, &c., Figs. 3 and 5, limit the rotation by engagement with a rocking device comprising stop-bars e, f and a spring h, this device being operated by a handle d to allow the pins to pass, while the pins act to position the stop-bar e by pressing down the stop-bar f by means of a plate g. The pins ride over a pivoted spring catch j, which acts to prevent backward rotation. When the compartments are successively filled, a projection m will prevent further rotation by contact with a stop n. The goods may then be removed on releasing the latch j from a lock k and reversing the rotation; or the device, if arranged in a door or wall, may be controlled, for emptying, from the inside of the door &c. The device may have a single compartment only, shaped, say, to receive a milk bottle.
