Title: Improvements in burnishing machines
Inventor: POYNTER CYRIL EDWARD
IPC: B24B39/02
Filed: 1955-08-31
Abstract: 833,989. Sizing bores of tubes. WEATHERLEY OILGEAR Ltd. Aug. 24, 1956 [Aug. 31, 1955], No. 25038/55. Class 83 (4). A machine for burnishing the bores of metal tubes 15 comprises a tube-holding fixture 2 and a reciprocating slide 1 which on each stroke forces a burnishing tool 6 through a tube. The tubes are fed in threes through holes 3a, Fig. 2, in a fixed upper plate 4 and into aligned bores 3 in the fixture which is rotatable stepwise. The fixture is adjustable by a hand wheel 21 for accommodating different lengths of tubes. Three parallel burnishing tools 6 are retained in bores in upper or lower stationary plates 4, 5 by spring detents 18. On the downstroke of the slide 1, which is actuated by an hydraulic motor fed by a variable speed pump, a double cam 9 on the slide first actuates a rack 8, meshing with a pinion 7 which, through a ratchet mechanism, indexes the fixture 2 through 90 degrees, thus bringing three unburnished tubes into alignment with the tools 6. Three push-rods 16 then engage the tools and press them through the bores and into the lower plate 5 and a cam 11 then withdraws the rack 8. On the upstroke the double cam 9 first indexes the fixture to bring three further tubes into alignment with the tools 6 which are pressed upwardly through the tubes by push-rods 17. A cam 12 subsequently withdraws the rack. The fixture is locked in the burnishing position by a plunger actuated through a push-rod 23 by cams 24 on the slide. A safety device is connected to the machine operating lever 22 for preventing operation if the tubes project above the fixture 2. Subsequently the burnished tubes fall by gravity down a discharge shoot 25. The tubes are for use as cylinders of shock absorbers.

Title: Method and apparatus for measuring linear displacements
IPC: G01D5/36
Filed: 1955-09-01
Abstract: 805,974. Photo-electric indicating systems. BOULY, H. G., (Neergaard, L. E. de). Sept. 1, 1955, No. 25205/55. Class 40 (3). [Also in Group XXXVIII] A linear distance is determined by causing a scanning device to scan a divided measuring element at a uniform speed to produce a signal having a frequency determined by the scanning speed and the spacing of the divisions, producing bodily movement between the scanning device and the measuring element to effect a phase displacement of the signal, and indicating the phase displacement. In the optical embodiment described with reference to Figs. 1, 2 and 3 of the Figures (Figs. 1 and 2, not shown), the movement of a member 1 having light transmitting and opaque areas as shown, relatively to a head comprising a motor-driven scanning disc 2, three photo-cells each receiving light through one of slots 9, 20, 21 forming part of the head, is to be detected. The member 1 may be an elongated glass bar having three sets of alternately opaque and transparent areas 3, 4, 5. The distance from the centre line of one area to the centre line of the next, the pitch P is the same for all three sets while each area has a width equal to P/2. The scanning member 2 has an opaque spiral on its transparent surface the centres of the turns being separated by P and the width of each turn being P/2. Light from sources not shown passes through the test bar 1 through the rotating disc and through slots 9, 20, 21 to one of three photo-cells each associated with one of the slots. As the scanning disc rotates constant frequency signals are generated in the photo-cells due to the co-incidences of the black and white portions on the disc with the transparent portions on the bar. If meanwhile, bar 1 moves, the frequency generated by the three cells will change. The cell receiving light from marks 5 will lose or gain 1 cycle for each <SP>1</SP>/ 10  inch moved by the bar while in the case of steeply sloping marks 4 one inch movement of the bar will lose or'gain a cycle and, in the case of gently sloping marks 3, 10 inches. Each photo-cell 11, 26, 27 (Fig. 4), controls the flashing through amplifiers 13, 30, 33 of lamps 34, 31, 14, each of which illuminates one of three scales on a disc 16 rotating in synchronism with the scanning disc. Thus the reading of the disc indicated stroboscopically will remain fixed until the bar moves, when the change in frequency will produce a phase change in the photo-cell output so that a different reading will be shown on the appropriate scale of the rotating disc. In an alternative arrangement (Figs. 20-21, not shown), an image of the marks on the record member is magnified before being scanned by a spiral scanner as already described.

Abstract: 425,132. Controlling shock-absorbers. AUBIN, E., Elmstead, West Wittering, near Chichester, Sussex, CLAREMONT, A. W., Vernon House, Sicilian Avenue, Bloomsbury Square, London, (Representatives of ROYCE, SiR F. H.), and HIVES, E. W., Rostherne, Duffield Road, Mickleover, Derby. Sept. 16, 1933, No. 25703. Addition to 401,770. [Class 108 (iii)] In the means described in the parent Specification for varying the damping action of a vehicle hydraulic shock-absorber, a second or overriding valve, the resistance of which is adapted to be varied by the driver, is placed between the pump and relief valve, and the connection or connections to the pressure chamber controlling the shock-absorber valve lead out on the pump side of the second valve. The Figure shows the pump, relief valve, overriding valve, and operating mechanism therefor. Upon the shaft a which is driven from the gearbox are mounted the governor a<1> and the eccentric carrying the strap a<2> and rod a<3> operating the pump plunger a<4>, as described in the parent Specification. The relief valve b<1>, having a chamfered end b<2> seated in the end of a conduit b<3>, is loaded by a rod b axially movable by the governor a<1>. On the upstroke of the pump oil is drawn from the reservoir c through a non-return ball-valve c<1> and on the downstroke liquid is forced through a conduit c<2> and non-return ball-valve d<1> to a chamber d<2> containing above the oil an air cushion which evens out pump pulsations. A spring - pressed valve prevents excessive pressures in the system. From the chamber d<2> the oil passes through a conduit d<3> to an annular chamber d<4> from which it can escape through holes e to a space g beneath the head g<1> of the overriding, spring-pressed, mushroom valve g<2>, or through holes f to a conduit g<4> leading to the pressure chamber, (not shown), controlling the shock-absorber valve. Liquid escaping from the space g past the overriding valve enters a chamber h and passes through conduit b<3> to the relief valve b<1>. The liquid pressure in the compression chamber of the shock-absorber is dependent on the pressure of the liquid in chamber d<4> and normally the pressure on the valve g<2> is negligible so that the pressure in the chamber d<4> is dependent on the pump speed and the effect of the governor on the relief valve. By operating the linkage h<7>, h<6>, h<4>, h<3>, however, the driver can move the spring-seating h<2> to load the valve g<2>, thus increasing the pressure in chamber d<4>. According to the Provisional Specification the relief valve may be a ball-valve as shown in the parent Specification, or a mushroom valve having projections engaging slots to prevent its rotation, or any other valve adapted to be directly loaded.

Title: Method for the manufacture of oí¬c to c alkyl phosphorodichloridiothioates
Inventor: TABOR EDWARD JOSEPH
IPC: C07F9/20
Filed: 1961-07-18
Abstract: An O-C1-C3 alkyl phosphorodichloridothioate is obtained by reacting a C1-C3 alkanol with phosphorus thiochloride in the presence of a solvent, there being employed as the sole solvent a substantial excess of the alkanol and the reaction being carried out at a temperature at which no more than one mole of hydrogen chloride is evolved for each mole of phosphorus thiochloride employed in the reaction mixture. Preferred reaction temperatures are between -5 DEG C. and +35 DEG C. and it is preferred to use from 5 to 10 moles of the alkanol for each mole of phosphorus thiochloride.  When the reaction is complete the reaction mixture is advantageously diluted with cold water and the desired product separated from the diluted mixture.  The process is particularly suitable for continuous operation, the reactants being continuously introduced into the reaction zone and the reaction mixture continuously withdrawn and diluted with cold water, the product separated from the aqueous alkanol phase of the diluted mixture and the excess alkanol recovered by distillation and recycled to the reaction zone.  Examples are given for the production of O-methyl and O-ethyl phosphorodichloridothioates.
