Title: Improvements relating to braking mechanism
IPC: B60T11/10
Filed: 1939-03-03
Abstract: 525,910. Hydraulic brakes. PRATT, J. H., MANLEY, G. E., and GIRLING, A. H. G. March 3, 1939, No. 6926. [Class 103 (i)] A hydraulic master cylinder, the pipe lines of which are connected to one brake, is mounted on a lever connected by mechanical means to another brake whereby movement of the master piston operates one brake hydraulically and by the reaction of the hydraulic pressure on the cylinder the lever is actuated to operate the other brake. The master cylinder 8 mounted in the end 9a of a lever 9 is connected by link 10 to the rear brakes of a vehicle and by pipe 17 to the front brakes. Thus when pressure is applied to the head 5 of the plunger 7 the front brakes are applied through the pipe 17 and the reaction of the hydraulic pressure actuates the lever 9 to apply the rear brakes. The plunger 7 has a sealing ring 7a such as described in Specification 511,546, [Group XXVI], and a reservoir communicates with the cylinder through pipe 14 and passages 8d in the retracted position of the plunger. A spring 21 housed in a telescopic casing 23, 24 returns the plunger. Liquid which may leak past the plunger escapes from the casing by passages 8f. A corrugated rubber member 25 closes the aperture in the floor board 26. In the event of failure of the hydraulic system, the rear brakes are applied by engagement of the plunger with the cylinder end and if the mechanical connections to the rear brakes fail, the lever 9 abuts on a stop 22 which permits of the hydraulic operation of the front brakes. According to Fig. 3, the lever 9 is connected to the rear brakes by a telescopic link 27 lever 28 and rod 10 and independent operation of these brakes by a hand lever is effected by a link 30 and lever 29 pivoted on the lever 28 and adapted to engage an abutment 28a on the lever. In another arrangement the lever 9 carries a second lever linked to the rear brakes and operable either by the lever 9 by an abutment on that lever or independently by a hand-lever.

Title: Improvements in and relating to measuring gauges
IPC: G01B13/08
Filed: 1944-04-15
Abstract: 577,294. Fluid-pressure servomotorcontrol systems. SOLEX, Ltd., WATTEBOT, L. E., and TAYLOR, J. W. April 15, 1944, No. 7000. [Class 135] [Also in Group XIX] In a gauge of the type comprising a nozzle or nozzles in connection with a source of pressure fluid and functioning by the indicated variation in pressure or rate of leakage flow from the nozzle or nozzles as set forth in Specifications 341,365, 348,860, 367,700, 388,265, 508,828 and 555,802, [all in Group XIX], a thin resilient and flexible plate of impervious material, preferably metal, of definite thickness, is mounted in front of the orifice of each nozzle and has a plane contact-making surface for co-operation with the part to be measured. In an embodiment for measuring, for example, the thickness of a rack 9, Fig. 2, a thin metal plate 11 is pressed by springs 15 against the upper surfaces of the rack teeth, thus bridging the grooves and enabling true measurement by the nozzle 8. Rotation of a nut 18 lifts the rods 13 and the attached plate 11 clear of the workpiece, as required. In an embodiment for measuring the external diameter of a circular toothed or splined object 32, Fig. 4, the thin metal plate takes the form of a sleeve 26, with a gap 33, spring urged against the workpiece and cooperating with nozzles 30. Means may be provided for opening the gap 33 to expand the sleeve 26, as necessary. In an embodiment for measuring the internal diameter of, for example, a rifle barrel, a thin sleeve 58, Fig. 7, is pressed against the internal surface by passing compressed air through circumferential tubes 59. A reading is then taken in the normal way by passing air through the nozzles 55. In another embodiment of the gauge for measuring internal diameters, solid rubber rings replace the inflatable rings, and screw means are provided for squeezing the sides of the rings to press the thin sleeve against the internal surface to be gauged.

Title: Process of making oil-soluble sulphonates of improved quality
IPC: C07C309/28
Filed: 1957-03-04
Abstract: A method of improving the surface-active properties of an alkali or alkaline earth metal salt of an alkylaryl sulphonic acid, the acid having an average molecular weight of 425-475, preferably 465-475, comprises incorporating therein at least 3% by weight, suitably up to 50%, of a mixture of alkali or alkaline earth metal mahogany sulphonates.  This mixture comprises 50-100% by weight of a salt of a mahogany sulphonic acid having an average molecular weight of 450-500, preferably 500, and 50-0% of a salt of a mahogany sulphonic acid having an average molecular weight of 350-400, preferably 400. The preferred salts are the sodium, calcium and barium salts, and the preferred alkylaryl sulphonates of several types mentioned are the postdodecylbenzene sulphonates containing mono- and di-alkyl benzene sulphonates in the approximate ratio 2 : 3.  One example illustrates the incorporation of the compositions in the form of barium salts into SAE 30 mineral oil to produce a detergent lubricating oil. Another shows the use of the compositions in avoiding the formation of an emulsion in a metathesis reaction in which a solution of sodium postdodecylbenzene sulphonate in a pale oil is shaken with aqueous calcium or barium chloride, whereby calcium or barium postdodecylbenzene sulphonate is formed.

Patent GB-1049212-A (GB)
Title: Heat shrinkable, foamed thermoplastic polymers
IPC: B32B27/18
Filed: 1965-02-19
Abstract: A method of preparing a heat-shrunk polymer comprises extruding a foamable thermoplastic polymer, chilling one surface of this extrudate to form a tough, non-porous skin, allowing the major portion of the polymer to expand to form a foamed layer thicker than, and integrally bound to the skin, hot-stretching the polymer in at least one direction, and finally shrinking the same by heat-treatment.  The polymer may be any thermoplastic resin, and includes polyamides, polyesters, polyurethanes, india-rubber, and cellulose esters and ethers, but preferred are styrene polymers which contain at least 70% by weight of styrene in their structure. If other types of polymer are to be used, it is preferred that they should be rigid, and relatively non-elastic. Foaming is brought about by volatile organic liquids, which liquids are not reactive with, and have no more than a slight swelling action on the polymer, and which are adsorbed on a conventional, finely-divided absorbent, the whole being mixed with the polymer before extrusion.  Chemical blowing agents in solid form may also be used.  To ensure even bubble formation, nucleating agents are used, these being combinations of compounds which react to yield carbon dioxide and water.  Wetting agents may also be used. Chilling is conveniently carried out by an air or air-water mist stream, flowing at 40-100 feet/second, and having a temperature between 0-100 DEG  C.  Stretching is performed by rollers. The shrinking process needs, in general, only a brief heating, as the process is rapid.  A stream of steam or hot air is conveniently used for this purpose.  The foams of the invention have particular application as form-fitting insulants for irregularly shaped objects, and also as a water-pipe insulant.  Reference has been directed by the Comptroller to Specification 998,180.

Title: Flaw detection
IPC: G01N27/90
Filed: 1956-03-07
Abstract: 856,692. Electric tests. IMPERIAL CHEMICAL INDUSTRIES Ltd., BRYANT, J. D. W., and PERRIAM, L. T. March 7, 1957 [March 7, 1956], No. 7229/56. Class 37 In a probe device for flaw detection of the type comprising a core having 'three flanges with a coil wound round a core between each pair of flanges, the flanges are provided with pole pieces the distance between the edge of each pair being less than the distance between the flanges. Since the gaps between the two sets of pole pieces are widely spaced, when the device is traversed along an object under test, e.g. inside a condenser tube there is time for the magnetisation caused by one coil to decay before the other gap passes the flow. As shown, a device intended to be traversed up the centre of a tube under test comprises a guiding nose 5, a magnetic core 8 provided with flanges 2, 3, 4, a pair of coils 1, 7 situated respectively between flanges 2, 4 and 3, 4. Pole pieces, also of magnetic material, are attached to flanges 2, 3, 4 respectively by pegs P. Gaps 15, 16 are provided between the coil and centre pole piece and are shorter than a coil; they may be fitted with a synthetic resin. An insulated handle 6 in which are connections 9, 10, 11 is provided. Fig. 2 shows the circuit. Coils 7, 8 are mounted in adjacent arms of an inductance bridge circuit the output of which is developed across resistor 23 and may be fed to amplifier 24, the bridge is supplied from oscillator 32. Initially the device is placed in a standard tube known to be free of flaws and resistors 21, 22 are adjusted to balance the bridge as indicated by meter 25 switch-connected to amplifier 24. The device is then put in a tube under test and amplifier 24 is connected to phase discriminator 26 fed with a reference signal from the oscillator. As the device passes a flaw a signal is produced first of one phase sense and then of the other and the phase discriminator feeds this signal through a D.C. amplifier to mark a recorder with a straight line which deviates first in one direction and then in the other. In order that changes in thickness may be detected, gaps 15, 16, may be of unequal length so that the line may deflect and stay deflected (Fig. 3 not shown). The sensitivity of the device may be increased by inclining the gaps (Fig. 4, not shown). Fig. 5 shows a device intended to be guided by flared opening 82 as the outside of a bar under test, flanges 71, 72, 73 are of a non-magnetic material e.g. "Lufnol" (Registered Trade Mark) pole pieces 79, 80, 81 are secured internally.
