Title: Soap compositions
IPC: C11D9/26
Filed: 1951-09-26
Abstract: A soap composition comprises a water-soluble soap and either a small proportion (i.e. up to 15 per cent of the weight of the soap), of an alkyl oleate of which the alkyl group contains 3-10 carbon atoms, or both a small proportion of mineral oil and a small proportion of an emulsifying agent which is not a soap. Such compositions form concentrated aqueous solutions containing at least 15 per cent and preferably 15-25 per cent of soap, based on the weight of soap and water together, and exhibit exceptionally low viscosities.  The preferred soap is sodium oleate.  The alkyl oleate may be n-butyl, n-hexyl or n-octyl oleate and is preferably present in an amount of from 2-10 per cent by weight of the soap.  The mineral oil has a preferred viscosity of 40-100 S.S.U. at 100 DEG F and both mineral oil and emulsifying agent may be present in an amount of from 2-10 per cent each, based on the weight of the soap.  Specified emulsifying agents are the polyoxyethylene mono-esters of fatty acids such as lauric, oleic or stearic acids, sulphonated long chain petroleum hydrocarbons, mahogany sulphonates, alkyl aryl sulphonates, fatty acid esters of sorbitan, such as sorbitan mono laurate, monopalmitate, monostearate, tristearate, or monooleate, diethylene glycol monolaurate, polyoxyethylene ethers, condensation products of alkyl phenols with ethylene oxide, sulphonated fatty acid esters and turkey red oil.

Abstract: 185,017. Rhodes, J. Aug. 25, 1921 Variable-speed gearing for obtaining three speeds and a reverse comprises gears sliding on three shafts, 2, 3, 4, Figs. 1, 6, and 12, gears 6, 7 being operable together while gear 5 may be movable independently, the whole being selectively controlled bv one hand-lever 13. The driving- shaft 10, Fig. 6, carries a gear 19 constantly driving a gear 8 loose on the driven shaft 4 through gears 20, 21. A double clutch gear 5 splined on the shaft 4 is slid to right and left to produce respectively a direct drive and the first reduction. A pair of integral gears 6, 6<a> are splined on the shaft 2, and the second reduced speed is obtained by sliding the gear 6 into mesh with the gear 5 when in the neutral position. Reversed drive is obtained by connecting the shaft 2 to the gear 5 through the gear 6a and the idle gear 7. The pair 6, 6a and the gear 7 are coupled so as to slide together by a fork 15, Fig. 1. making connection with a selector bar 17. The gear 5 is moved by a fork 11 and a bar 12, Fig. 12. The bars 12, 17 are formed with heads 14, 18 with unequal recesses so that the lever 13 by lateral movement may engage the head 18 only or both heads simultaneously, so that all the gears except 5, or alternatively all the gears may be moved together. The interlocking control is shown in Figs. 8 and 9. There is a laterally-sliding plate 23 having a snug m adapted to engage the head 14 and lock it when the head 18 alone is being operated.

Title: Automatic card stripping apparatus for carding engines
IPC: D01G15/80
Filed: 1954-08-04
Abstract: 791,472. Carding-engines. SUZUKI, S. Aug 4. 1954 [Nov. 12, 1953], No. 22587/54. Class 120(1) Automatic stripping apparatus for carding-engines comprises a traversing member movable in parallel with the axes of the carding cylinder and doffer and carrying stripping means having a suction opening elongated in the circumferential direction of the cylinder and by which the fibres are drawn, without damage, through the spaces between the needles of the card clothing so that they may be returned for reintroduction to the lap being fed to the machine. In the embodiment of Figs. 1 and 3, a nozzle 8, mounted on a valve 19 to which a pipe 21 leading to a suction fan 20 is connected and comprising a suction opening 6, traverses a cylinder 2 by movement relative to a rotating spindle 12 the screw thread of which is engaged by a gear screw 13 on a movable element 11 the sliding movement of which on a sleeve 9 is guided by the engagement of a yoke 14 with a rod 15. At each end of the traverse, a projection 30 or 31 lifts a stud 25 or 26 from a groove 28 or 28<SP>1</SP> in the spindle 12 which is thus freed for transverse movement under the action of a previously compressed spring 39 or 40 to engage either a flange 33 or a ring 34 with a cog-wheel 37 or 38 for rotation by a toothed wheel 35 or 36 which in turn is driven from a shaft 42 and gear wheel 43 or a wheel 44 and reversing train 45, 45<SP>1</SP>, the stud 26 or 25 at the opposite end of the apparatus engages the groove 28<SP>1</SP> or 28 to limit the movement of the spindle 12 the reversed rotation of which then urges the nozzle 8 on the stripping or the return stroke in accordance with which the valve 19 has been opened or closed by the engagement of,one arm of a bifurcated handle 19<SP>1</SP> with a projection 22 or-23. The stripping arrangement for the doffer is similar and the fibre and waste material passes through the pipe 21 to the fan and thence through a pipe 55 to a nozzle 41 from which it is blown against a projection 56 for return to the taker-in or disposal. In the construction of Fig. 8, an endless belt 46 has one or more suction openings, as at 6, according to its length in relation to the width of the cylinders, and travels on rollers 47, 48, the latter driven from a motor through chain-wheel 52, shaft 50, and bevel wheels 49 and 51, over a vacuum chamber 53 to an exhaust opening 54 of which is connected the pipe 21, the surface of the belt 46 may be curved to conform to the card surface to be stripped, Fig. 9 (not shown).

IPC: F04D15/00
Filed: 1952-09-11
Abstract: 719,749. Specific gravity estimating apparatus. NAPIER & SON., Ltd., D. Sept. 3, 1953 [Sept. 11, 1952]. No. 22794/52. Class 97(3) [Also in Group XXVII] Apparatus for sensing changes in the specific gravity of a liquid, comprises a rotary impeller which runs in the liquid and produces a pressure differential proportional to the specific gravity of the liquid and to the square of the speed of rotation, means for converting this pressure differential into a force, a rotary device driven synchronously with the impeller for producing a force proportional to the square of the speed of rotation, a balancing device upon which the two forces act in opposition and which has a movable part for maintaining the balancing device in equilibrium, and an output member which is constituted by, or which moves with, the said movable port. The apparatus shown is adapted for incorporation in the fuel supply system of an internal combustion engine and includes a shaft 10 which may be driven by the engine, this shaft carrying an impeller 11, rotatable in a casing 12, and a pendulum-type centrifugal device 13. A chamber 14 in the impeller casing 12 communicates through a pipe 15 with the fuel supply system between the tank 16 and a pump 17 and another chamber 18 in casing 12 connects at 19 with the fuel supply system. The pressure differential between chambers 14, 18 is applied across a diaphragm 20 connected by a rod 21 to a balancing lever 23 so as to apply a force on said lever which is proportional to the specific gravity of the fuel and the square of the rotary speed of the impeller 11. At the same time a force proportional to the square of the rotary speed of the shaft 10 is applied by the sleeve 25 of the centrifugal device 13 to the lever 23 at 24. The lever 23 slides through a member 27 which acts as a fulcrum and is carried by the piston rod 28 of a servo-motor 29 so that in order to balance the couples produced by the two forces acting on the lever 23 it is necessary to move the piston rod 28. This rod is moved by fluid from the fuel supply system flowing through a pipe 34 or 35 according to the position of a valve 32 connected to rod 21, the position of the valve depending upon the direction of unbalance of lever 32 and being moved to a neutral position when equilibrium is attained. The equilibrium position of fulcrum 27 is an indication of the specific gravity of the fuel and an indicator or a part 36, adapted to adjust the fuel supply system to compensate for specific gravity changes, may be coupled to the piston rod 28.

Title: Variable speed gears
IPC: F16D11/12
Filed: 1929-07-25
Abstract: 337,033. Denman, W. July 25, 1929. Clutches, c l a w ; operating clutches.- A clutch more particularly for use in motor-car variablespeed and reversing gearing comprises an arrangement of helically winged pawls pivoted into engagement with a toothed ratchet wheel by axial movement of a rotatable ring having helical slots engaging said wings. As shown in Fig. 3, attached to the driven shaft 4 is a boss carrying ratchet teeth 6 engaged by pawls 7 pivoted on pins 8 to a bossed drum 5 keyed to the driving shaft. Two pairs of pawls, each pair engaging oppositely directed ratchets to give a reverse drive, are used and each pawl has an integral helical wing 9 engaging a helical slot in a cylindrical ring 11 feathered to the drum 5 and having a flange 12 running between grooved rollers 20 on an operating frame 15. This frame carries pins 17, Fig. 7, guided by oblique cam slots in fixed members 19 so that by pushing on a rod 31 the frame is given a helical motion which communicates through the rollers 20 an axial motion to the ring 11 to pivot the pawls into engagement. For each pair of pawls the wings with their slots are oppositely inclined so that each pair is pressed into or lifted out of engagement by movement of the ring 11. In the constant mesh countershaft variable-speed and reversing gear shown in Fig. 7, the larger of a pair of meshing wheels, indicated by chain lines 42, is mounted freely on. its shaft and is recessed to form a grooved boss carrying the ratchet teeth 6. The pawl-carrying boss 5 is keyed to the shaft and the wheel is clutched to the shaft to give the required speed by operation of the appropriate frame 15. For operating the frame there is shown a push button mounted in a fixed frame and universally jointed to the rod 31. A blade spring locking catch retains the button in the engaged position of the clutch and it is spring returned to the disengaged position on release of the catch. In the speed gear this catch is modified and comprises a spring- loaded member 44 adapted to lie behind and prevent return movement of a cam 45 on the frame 15 when this has been operated to engage the clutch. The catches for the clutches on each shaft are mounted on a shaft 43, and on a parallel shaft linked to it, so that when any one frame is operated all the others are freed. The catches may also be freed by hand or pedal through a rod 48. In a simple form for clutching a loose pulley to a shaft the operating frame is dispensed with and the ring 11 is directly operated by a fork engaging a groove in a sleevelike axial extension of the ring feathered to a similar extension of the pawl-carrying drum 5. The clutch is housed within the overhanging pulley rim. In another form only a single set of pawls and a single ratchet wheel are used. According to the Provisional Specification operation of the catch rod 48 by hand, foot, or knee gives a free engine and a free wheel, and the pawls may be held in position partly by spring means.

Patent GB-1025164-A (GB)
Title: A radiation dosimeter
IPC: G01T1/11
Filed: 1964-06-03
Abstract: A personnel radiation dosimeter utilizes resistive heating means on to which is attached, by using radiation and light transparent binding means, dosimetric lithium fluoride, i.e. Li F. which contains impurities, e.g. Mg, Al, Ca, Ti &c. which improve its thermoluminescent properties.  The heating means is a rectangular base 12 of e.g. graphite cloth impregnated with potassium silicate to retard oxidation.  For convenience, the lithium fluoride 14 is deposited on to a porous, ceramic strip 13, of e.g. glass fibre, which is shorter than the base 12.  Mica platelets 16, 17 act as protective windows, have cut-outs 18, and are of a length between that of the base 12 and the strip 13.  All the units are glued together using potassium silicate. Nickel end tabs 22 are crimped over the ends of the dosimeter to cover the ends 19 of the base 12 and the cut-outs 18.  The ends of the base are covered with silver paste 21 to improve the contact between the base and tabs 22.  The lithium fluoride is initially deposited on to a ceramic strip 13 by using an open-ended cylinder which is placed vertically on the strip, and is filled with potassium silicate solution carrying a dispersion of lithium fluoride.  The process of filtering the dispersion from the solution may be accelerated by suction, so that finally the area treated contains a lithium fluoride deposit and interstitial potassium silicate solution.  The strip is dried and baked and the dosimeter assembled and baked. The lithium fluoride may be deposited in a wafer-like slab and joined directly to the base 12.  The mica covers 16, 17 may be omitted if required.  If the lithium fluoride is to be deposited on to mica plates directly, gravity deposition from the binder solution may be carried out.  The dosimeter may be marked for later identification.  Read-out of an exposed dosimeter consists of heating up the dosimeter by passing a current through the base 12 and measuring the light emitted (see Division G1).

[Class 139.] A time switch employed in connection with point and signal lever mechanism for railways, comprises a member moved by the point or signal lever against the action of a spring, and escapement mechanism regulated by an adjustable pendulum for retarding the return of the member. When a segment 60 is swung in either direction, a cam portion 62 depresses a plunger rod 54 and a bridging contact 59 is removed from fixed contacts 58. The rod 54 acts through a rod 36 to rotate a cylindrical casing 9, to which it is attached by a riveted nut 35, against the action of a spiral spring contained within the casing 9. The casing 9 drives a ratchet wheel 23, which, however, transmits motion to a wheel 20 only when it is rotated anticlockwise. The movement of the wheel 20 is regulated by a pendulum 29 through escapement mechanism 24, 26, 27. Thus when the segment 60 is returned to its normal position, the spring rotates the casing 9 to return the rod 36 to its raised position at a rate determined by the pendulum 29. The length of the pendulum 29 is varied by varying its point of attachment to the escapement shaft 28, or by varying the position of its bob 30. The downward movement of the rod 36 is adjustably limited by a nut 39, the effective length of the rod 36 being adjusted by rotating it in the nut 35. The strength of the spring may also be adjusted.
