Patent GB-788322-A (GB)
Title: Improved soluble oil composition
Inventor: ERVINE WILLIAM DENIS
IPC: C10M173/00
Filed: 1955-03-29
Abstract: A composition which is emulsifiable with water, and which is suitable for use as a cutting oil or textile oil, comprises a mineral lubricating oil having a viscosity of 70-200 seconds Saybolt Universal at 100 DEG  F., an emulsifying agent and a minor proportion of the benzoic acid salt of triethanolamine.  The emulsifying agent may be a metal petroleum sulphonate, particularly sodium petroleum sulphonate.  The composition may also contain emulsion stabilizers (e.g. alkali metal or alkaline earth metal naphthenates, diethylene glycol or methyl, ethyl, isopropyl or butyl alcohol), antifoaming agents (e.g. silicone oils or vegetable waxes such as candelilla wax), oiliness or extreme pressure agents (e.g. isopropyl oleate, tricresyl phosphate, chlorinated wax, fatty oils, or sulphurized or phosphorized fatty oils) and fungicides (e.g. sodium o-phenyl phenate).  Where transparent emulsions are desired, sodium rosinates may also be added.  The triethanolamine benzoate may be formed in situ by dissolving benzoic acid in the lubricating oil and adding sufficient triethanolamine to neutralize this acid together with any naphthenic, fatty or rosin acids that may be present.  In the examples, a blend of mineral lubricating oil, sodium petroleum sulphonate, naphthenic acid, caustic soda and water is prepared and to this blend triethanolamine, benzoic acid, isopropyl alcohol and water, with or without caustic soda, are added.  For comparison purposes, similar compositions are described in which the triethanolamine is omitted, sufficient caustic soda being present to cause the formation of sodium benzoate in situ, or in which the benzoic acid is omitted. Specification 689,740 is referred to.

Patent GB-819093-A (GB)
Title: Announcing machine
IPC: G11B5/55
Filed: 1957-03-22
Abstract: 819,093. Magnetic recording and reproducing apparatus. HANET, P., and HANET, G. March 22, 1957 [March 22, 1956; Sept. 10, 1956], No. 9497/57. Class 40 (2). An announcement machine employs a wide endless band carrying a plurality of recorded announcements on longitudinal parallel tracks, and has record-reproduce means which can be advanced transversely of the band to each of the track positions and returned to a starting position after some or all of the announcements have been reproduced. The band 10, Fig. 3, Which may be a magnetic record carrier, but not confined thereto, is supported on rollers 11, 77, 78, 79 and frictionally driven by a shaft 76 coupled to a motor 48 by a belt. The band 10 is provided with slot-like apertures serving to operate a micro-switch 57 to stop the motor at the end of each record track. The magnetic head 9 is supported on a carriage 4, 5 slidable along a square-sectioned bar 14, and.is biased to the right, as viewed in Fig. 1, by a cord 37 attached to a spring-loaded drum 38 but is normally prevented from moving in that direction by a spring-loaded pawl 26, Fig. 7, which engages teeth on the bar 14. Movement step by step of the carriage 4, 5 against the tension of drum 38 is effected by impulses from a solenoid 30 which, via a cord 30 and pulleys 32, 33, Fig. 8, oscillates a bar 24, and by engagement with another spring-loaded pawl 27 moves the carriage 4, 5 step by step along bar 14. Adjustable stops to limit the traverse of the carriage are provided on a rod 7 which is manually rotatable to a number of angular positions according to the particular stops it is desired to bring into operation. The rod 7 is provided with limited end play and at one end has a wheel in a groove of which rests the feeler arm of a micro-switch 50 having two stable positions, the normal one in which the switch is open, and the other when the switch is closed. When the carriage 4, 5 engages one of the stops to the left of the carriage, the rod 7 is moved to the left to bring switch 50 to the closed position whereby a solenoid 41 is operated to move a bellcrank 43, Figs. 1 and 9, clockwise, as viewed in those Figures, and via a cord 46 rotate the shaft 39 carrying pawl 27 to a position in which the latter disengages pawl 26 from the teeth of bar 14 and allows the carriage to slide 'back under the influence of drum 38. Engagement of the carriage with one of the right-hand stops on rod 7 causes the switch 50 to be reset to its open position to de-energize solenoid 41 and cause the pawls 26, 27 to reengage. A switch connected in parallel with switch 57 enables any announcement to be repeated at will. The embodiment is particularly directed to the use of the invention for a destination announcement machine on a vehicle, and details of the controls and control panel are given with reference to Figs. 10, 11, 12 and 13 (not shown).

Title: Improvements in or relating to milling cutters and like tools
IPC: B23C5/20
Filed: 1952-04-16
Abstract: 694,292. Milling-cutters. HOOLE, C. B., and WATSON, C. April 16, 1952, No. 9517/52. Classes 83 (i) and 83 (iii). [Also in Group XXIII] Casting composite articles.-A multi-edged milling cutter, or the like, has a body 1 cast from high tensile bronze and cutting tips 2 of tungsten-carbide or like sintered hard metal so shaped as to be secured against movement relatively to the body when the latter is cast around them. The front and the back faces of the tips may be of irregular shape to key with the body. Ribs, extending lengthwise and across the back faces of the tips, may retain the tips against movement axially and radially of the body. The tips may have dove-tail ribs 4, Fig. 4, extending lengthwise thereof and of greater width at the root of the tip than at its outer edge. Instead of the ribs tapering, or in addition thereto, they may be thicker towards the root of the tip or recessed as at 10 in Fig. 7. In this Figure, the tip has a rounded rib 9 and may be tapered or thickened as in the case of the rib 4. The tips may be arranged on the body in other than a radial direction, or with their front faces set at an angle to the axis of the body, e.g. as in staggeredtooth cutters; the cutting edges may be interrupted by removing parts thereof or by spacing a number of tips in line with each other along the length of the body. The tips may also be shaped for form-milling, end-milling or multiple counter-boring. A hub 16, Fig. 1, which may have been machined previously and formed with holes 20 and a flat 19 to key with the cast body, is cast into the body 1. A block (not shown), may be used instead of a complete bush and may be formed with a balancing mass. The body may be cast from an aluminium-bronze alloy on a jig-plate 12, Fig. 10, in a mould of sand, the tips having been positioned in grooves 13 in the plate 12 before applying a sand-cover 14. The body metal and that of the tips may unite during casting as in a brazing operation. This effect may be assisted by coating the tips with silver solder or silicon-bronze. Shrinkage of the body upon setting also assists it to grip the tips.

Title: Improvements in or relating to flux reset transductors
IPC: H03F9/06
Filed: 1965-03-05
Abstract: 1,148,495. Resetting magnetic amplifiers. BRENTFORD ELECTRIC Ltd., and M.G.J. FRY. 6 June, 1966 [5 March, 1965], No. 9543/65. Heading H3B. In a resetting magnetic amplifier the degree of resetting is measured and resetting is controlled in accordance with the measured value. In Fig. 2 magnetic amplifier 14 has a load winding 13 and a resetting winding 16, the latter being energized from source 17 through a transistor gate 19. As the magnetization of the core falls to its remanence value at the end of the load half cycle an E.M.F. is induced in winding 16 and is integrated by RC circuit 22, 23. During resetting, gate 19 is initially open and the back E.M.F. generated in winding 16 by the changing flux is also integrated. When the integrated voltage on capacitor 23 equals a control voltage applied at 25, 26 a bistable circuit 27 is switched and gate 19 is closed to terminate the resetting. During a load half cycle the core of the magnetic amplifier becomes saturated, and while the flux is changing an E.M.F. is induced in winding 16, causing current to flow in a trigger device 36. The waveform is clipped, differentiated and rectified to provide pulses at times corresponding to the instants when the core becomes saturated by current in the load circuit. Power source 11 is also connected to a trigger device 37 which generates a pulse at the time each load half cycle begins. The two pulse trains are combined and supplied to the base of a transistor 28 connected across capacitor 23 so that the capacitor is discharged at the beginning of each load half cycle and at the moment when the core saturates. In a modification transistor 28 is triggered at the beginning of each load half cycle by means of a circuit including a source synchronized with sources 11, 17, a full-wave rectifier, a clipping circuit and a differentiating circuit. In this case the change in flux as the core magnetization falls from saturation to remanence at the end of the load half cycle is not taken into account. Transistor gate 19 preferably consists of several transistors in pandlel, and the transistors may be protected from excessive back E.M.F. by a series circuit consisting of a Zener diode and a resistor connected across the emitter-collector circuit of the transistor gate. It is stated that two transductors may be arranged to supply a load in push-pull, that two transductors in parallel may share a common integrator circuit and that the invention may be applied to polyphase power circuits.

Filed: 1928-03-30
Abstract: 314,578. Chantry, H. R. March 30, 1928. Securing pulleys, propellers &c. on shafts.- Comprises a development of the means for securing rotary elements together described in Specification 274,726 in which there are mutually engaging eccentric parts such as 27, 28, Figs. 6 and 7. An element 25 which may be the boss of a pulley or propeller is to be secured to a shaft 26. The invention consists in the use of means 15, 16 for guiding the eccentric parts into proper engagement when assembling. Thus when boss 25, Figs. 6 and 7, is being slid on to the end of shaft 26, a slot 16 on the boss must be brought into register with a snug 15 on the shaft. The female eccentric 28 is then in line with the male eccentric 27. When the eccentric parts are fully engaged, the snug 15 passes clear of the slot 16 into an annular cavity 17, Fig. 7. An annular flanged nut 7 not only thrusts the boss 25 home, but also serves to withdraw it in disassembling. A pulley mounting is described in which the male eccentric is on the pulley boss.
