Title: Improvements in and relating to submersible electric motor driven pumps
Inventor: HUNT JAMES WEBSTER
IPC: F16C33/66
Filed: 1964-02-07
Abstract: 1,044,393. Bearings; lubricating. CONCH INTERNATIONAL METHANE Ltd. Feb. 7. 1964, No. 5238/64. Heading F2A. In a method of discharging a liquid at or near its boiling-point by means of a wholly or partially immersed electric motor-driven submersible pump, a sufficient flow of said liquid is maintained across the motor bearings of the pump to avoid formation of vapour in the bearing housings and to cool and lubricate the bearings. The flow of liquid across the bearings may be maintained just above a value determined by the formula Q b /(h s -h 1 ), where Qb is the rate of production of frictional heat in the bearing housing, h s  is the enthalpy at pump suction and h 1  is the enthalpy at the bubble point corresponding to pump discharge pressure. In an embodiment, a motor end bell of a submersible electric motor driven pump has passages 5, 5a, Fig. 2 (not shown), formed therein through which cooling liquid can flow from pump discharge 6 to the inlet side of ball-bearing housings and to the inlet side of a motor housing 8. Clearance is provided between the rotor/stator assembly 9, 10 and the motor housing 8 to allow the liquid to flow through the motor housing and then pass through an outlet 12. An annular gap A is formed in bearing retaining members 13, 13a, 14 and 14a so as to restrict the flow of the liquid and thus absorbs frictional heat from the bearing without the formation of vapour in the bearing housings. The outlet 12 may be restricted to prevent a pressure drop in the motor housing 8; alternatively, an inlet gap C to the motor housing 8 is restricted to cause a pressure drop in the motor housing. In the latter case the liquid in the housing is vaporized in compensation for electric losses therein, and cools by the absorption of latent heat.

Title: Improvements in or relating to methods and apparatus relating to information transfer devices
IPC: H04L13/08
Filed: 1965-02-08
Abstract: 1,091,872. Data transmission systems. DASA CORPORATION. Feb. 8, 1965 [Feb. 10. 1964], No. 5388/65. Heading H4P. Telegraph signals read from a magnetic store in return-to-zero form are converted to non- return-to-zero form prior to transmission over a telegraph line. The output of the store passes to a bi-stable circuit which is reset by bit-rate clock pulses from an oscillator set in operation by the first (start) pulse from the store. The output from the bi-stable circuit sets an output bi-stable circuit and also resets that output circuit after a delay, thereby developing the NRZ signals. The arrangement may be used to add fixed information to the variable data from a keyboard. The magnetic store may be filled from a keyboard or tape. The signals from the tape trigger a monostable circuit which feeds the magnetic store, the signals being gated by clock pulses from an oscillator controlled by the Start bit. Correct character spacing in the store is ensured by reading the tape at intervals determined by a monostable circuit triggered by the Start bit.

Title: Manufacture of new carboxylic acid esters of aromatic sulpho-dicarboxylic acids
IPC: C07C303/22
Filed: 1942-04-23
Abstract: Carboxylic acid esters of aromatic sulphodicarboxylic acids are obtained by treating one molar proportion of the said aromatic acids, their anhydrides or sulphonic acid salts with one molar proportion of an alcohol having at least 16 carbon atoms, and then treating the resulting monoester with an alcohol having at least 8 carbon atoms, the esterification being effected at 80-90 DEG  C. with reduced pressure in the presence of a solvent forming an azeotropic mixture with water.  In a modification, the lower alcohol is used first.  The products or their salts with metals, ammonia or amines are used as wetting, emulsifying, softening, cleansing and levelling agents in the textile industry.  In examples:  (1) a mixture of octadecyl alcohol with a little cetyl alcohol is esterified with 4-sulphophthalic anhydride and the product reacted in benzene with 2-ethylhexanol-1 and neutralized; the resulting diester is used with 4-sulphophthalic-21-ethylhexyl-21-ethylbutyl ester for emulsifying oleic acid; (2) the monoester obtained in the first stage of example (1) is esterified with a mixture containing oleic alcohol and a little cetyl alcohol and neutralized with ammonia; the resulting diester in conjunction with 4-sulphophthalic acid 21-ethylhexyl-21-ethylbutyl ester and diethylene glycolmonoethylether is used for emulsifying oleic acid; (3) 4-sulphophthalicanhydride is esterified first with a mixture of oleic alcohol and cetyl alcohol and then with diethylene glycolmonobutylether.  The Specification as open to inspection under Sect. 91 comprises also the use of the halides and esters of the sulphodicarboxylic acids for the esterification, and one carboxylic group may be esterified with an alcohol containing at least 12 carbon atoms and the other with phenols or alcohols containing at least six carbon atoms.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to cases or holders for sticks of cosmetic and the like
IPC: A45D40/02
Filed: 1933-02-23
Abstract: 403,246. Cases for sticks of cosmetic &c. MORRISON, S., 24, Nathan Davis Place, New York, U.S.A. Feb. 23, 1933, No 5604. Convention date, Feb. 23, 1932. [Class 18.] A case for a stick of cosmetic &c. comprises an outer casing 2, Figs. 1 and 3, with a hinged cover 5, an inner slidable sleeve 8 to which a plate 16 is pivoted at 17, and a cosmetic carrier slidable in the sleeve. When the carrier is pushed upwards by means of a knob 21 connected thereto and running in slots 8a in the sleeve and casing, the knob pushes on the surface 25 of the plate 16 and causes the sleeve to rise, the latter pushing open the cover. After the cover has opened, a projection 16a on the plate 16 engages against a stop 2b punched in the casing and arrests the movement of the sleeve and also swings the plate over so that the slots 8a are uncovered, the carrier then continuing its movement and projecting the stick. The sleeve carries a pin 11 the ends of which engage in slots in the flanges of the cover, the pin seating in notches in the upper ends of the sides of the casing when the cover is closed. A notch 18 in the carrier prevents the pin 17 from locking the carrier to the sleeve. A spring strip presses the sleeve against the front of the casing to hold it in any required position. The casing is of metal held in a base 4 by friction or soldering. The knob 21 is threaded to or a driving fit in the carrier and a reinforcing member is attached to the inside of the carrier at the point of attachment. In a modification, the cover carries a depending finger 41, Fig. 11, which, as the sleeve moves upwards to push open the cover, moves into a rectangular opening 44 in the sleeve. When the sleeve is being retracted the portion above the opening 44 engages the finger 41 and closes the cover. The opening movement of the cover is limited by a detent 46 striking the top of the casing. The pin attached to knob 21 also serves as a stop to prevent the stick being pushed too far into its carrier.

Abstract: 918,522. Elastic-fluid turbines. GOTAVERKEN A.B. Feb. 15, 1961 [Feb. 17, 1960], No. 5678/61. Class 110 (3). In a turbine comprising guide blades fixed to the turbine casing and a shroud ring encircling the blades, the blade roots are joined to an inner ring-shaped member fastened to the casing, and the inlet area is adjusted by reducing the guide blade height and by machining the inner diameter of the shroud ring to correspond. The guide blades 6, Fig. 1, are fixed to an inner part 4 of the turbine casing by means of an inner ring 7 which, as shown in Fig. 3, may be formed in sectors each comprising four blades. The inlet area of the flow passages 15 between the blades 6 can be adjusted to the required value by machining the blades to decrease their height. The shroud ring 9 surrounding the blades 6 and a guiding-piece 10 at the inlet 3 may have sufficient thickness to allow them to be machined to match the adjusted blade height. Alternatively, if the reduced blade height is confined to three alternative sizes only, the shroud ring 9 and the guiding-piece 10 may be made in a range of three different sizes, each size mainly corresponding to one of the three alternative blade heights. By the correct choice of ring and guiding-piece it is possible to make a fine adjustment with little machining. Tho shroud ring 9 may be provided with corresponding members 11 at the outlet. As shown in Fig. 3, the area of the flow passages 15 decreases towards the outlet ends of the blades, and the outlet area can consequently be increased by machining the trailing edges of the blades as at 16 to increase the outlet width of the passages 15 from a width 17 to a width 18. A consequential increase of the clearance between the blades 6 and the rotor is avoided by providing distancepieces between the ring 7 and the casing part 4 or by providing the part 4 with a machining allowance. If the blades 6 are arranged in sectors, the machining of the different sectors may be varied to vary the outlet area around the circumference, for example to allow for the inlet chamber being of volute form, to allow for local constrictions, or to take account of conditions in the vicinity of the inlet conduit.
