Filed: 1957-04-04
Abstract: 914,930. Spherical diaphragms. AEROJETGENERAL CORPORATION. April 4, 1957, No. 11087/57. Drawings to Specification. Class 13. Sound waves are generated for underwater signalling or for seismic prospecting, by a flexible bladder immersed in the fluid and inflated by air. The bladder is caused to vibrate as a diaphragm, i.e. expand and contract, by the alternate admission and emission of air, through a motor-operated valve, the speed of operation of which determines the sound frequency. The sound wave of larger amplitude is produced when the valve is operated such that admission and emission pulses occur at the bladder resonant frequency. The pressure pump supplying the expansion pulse feeds into a tank reservoir and the emission may take place freely to the atmosphere or may be assisted by an exhaust pump. The bladder is of neoprene or rubber so as to withstand repeated stretching.

Patent GB-769953-A (GB)
Title: Improvements in or relating to siloxanes
IPC: C07F7/08
Filed: 1955-04-20
Abstract: Siloxanes suitable for dipping varnishes, impregnating solventless resins and for making elastomers, have the average general formula [CH2 = CR.COOCH2]R1n.SiO 3-n/2 wherein R is hydrogen or a methyl radical, each R1 is a monovalent hydrocarbon radical and n has a value from 1 to 2 inclusive. Preferably the polymer is made by reacting an alkali metal salt of acrylic or methacrylic acid with a halomethylsiloxane. Alternatively sodium or potassium acetate may be reacted with chloromethylsiloxanes and the resulting acetoxymethylsiloxane may then be heated with acrylic or methacrylic acid, in the presence of a polymerization inhibitor such as hydroquinone, at a temperature above the boiling point of acetic acid.  Specified are siloxanes in which R1 is methyl, ethyl, octadecyl, vinyl, allyl, hexenyl, cyclohexyl, cyclohexenyl, cyclopentyl, phenyl, naphthyl, xenyl, tolyl or benzyl.  The polymers may be copolymerized with 0.001 to 99.999 mol. per cent of siloxanes of the average general formula <FORM:0769953/IV(a)/1> wherein each R11 is a monovalent hydrocarbon, acetoxymethyl or halogenated hydrocarbon radical and m has a value from 1 to 3. In examples (1) potassium methacrylate, bischloromethyltetramethyldisiloxane, methacrylic acid and dimethylformamide were refluxed to yield, after filtration and removal of solvent, liquid <FORM:0769953/IV(a)/2> (2) the product of (1) was copolymerized with hexamethyldisiloxane in the presence of conc. H2SO4 and trifluoroacetic acid to yield <FORM:0769953/IV(a)/3> which on heating with benzoyl peroxide at 70 DEG  C. under nitrogen gave a tough, plastic material suitable as a moulding composition; (3) bisacetoxymethyltetramethyldisiloxane, hexa-methyldisiloxane, acrylic acid, conc.H2SO4 and hydroquinone were refluxed under nitrogen and distilled to give <FORM:0769953/IV(a)/4> <FORM:0769953/IV(a)/5> and a residue of <FORM:0769953/IV(a)/6> (4) methacryloxymethylpentamethyldisoloxane was co-polymerized with octamethylcyclotetrasiloxane in the presence of conc.H2SO4 to yield liquid <FORM:0769953/IV(a)/7> which gave a resilient material when heated with benzoyl peroxide at 70 DEG  C. under nitrogen; (5) bis-methacryloxymethyltetramethyldisiloxane was copolymerized with phenyl methyl polysiloxane to give <FORM:0769953/IV(a)/8> which polymerized to a hard tough resin when heated at 120 DEG  C. under nitrogen in the presence of azo-iso-butyronitrile; (6) chloromethylheptamethylcyclotetrasiloxane, sodium acrylate and dimethylformamide were refluxed to yield <FORM:0769953/IV(a)/9> which was then copolymerized with vinylmethyl and chlorophenylmethyl siloxanes.

Title: Improvements in and relating to turbochargers
Inventor: BOZZOLA RICCARDO ANTONIO
IPC: F02B39/14
Filed: 1964-03-19
Abstract: 1,029,496. External band brakes; external shoe-drum brakes. SCHWITZER CORPORATION. March 19, 1964, No. 11573/64. Heading F2E. [Also in Division F1] An I.C. engine turbo charger has braking means including a braking shoe 54, Fig. 7, normally biased against its shaft so as to prevent rotation, the shaft being released when a  predetermined pressure of the shaft lubricant is  present in the braking means. When shaft 57 is stopped and there is no lubricant pressure in its bearings, spring 51 acts through piston 52,  spacer 62 and the toggle linkage 58, 59 to force the shoe 54 against shaft 57. After starting the lubricant flows through spaces between block 56 and bore 47 and increasing lubricant pressure overcomes spring 51, thus causing piston 52 to move towards cap 49. A leaf spring 69 lightly biases spacer 62 towards surface 53, thus allowing shoe 54 to move away from shaft 57 which can then rotate. In another embodiment a piston 17, Fig. 2 (not shown), which is corrected  through a projection 21a to a rotatable sleeve 28 secured to one end of a helical band 32 which  is anchored at its other end to a fixed sleeve, is acted on by a spring 24 so that band 32 prevents rotation of shaft 31 when there is insufficient lubricant pressure in chamber 18. A force multiplying linkage may be interposed between  piston 17 and stem 21.

Title: Improvements in or relating to surface generating machines
IPC: B24B13/00
Filed: 1950-05-10
Abstract: 671,173. Lens grinding machines. KODAK, Ltd. May 10, 1950 [May 10, 1949], No. 11669/50. Class 60. [Also in Group XXVIII] A grinding machine for generating surfaces comprises a rotatable work-spindle 10, a rotatable tool-spindle 12 normally urged towards the work-spindle at an uncontrolled rate, and a governor mechanism which restrains the rate of feed of the tool-spindle from exceeding' a predetermined value but which allows the spindle to move freely away from the work. The spindle 12, carrying the grinding cup-wheel 11, is mounted in a sleeve 13 and is rotated directly by an electric motor M. The assembly is angularly adjustable on a plate 14, by means of a screw 18, to vary the radius of curvature on the work W. The plate 14 is movable vertically to allow the work to be replaced. The wheel 11 is fed to the work by air pistons 32 controlled by a solenoidactuated valve 36, through lines 40-44. The exhaust lines 40, 41 each have pressure-control valves 45. Until the wheel contacts the work, its rate of advance is limited by the engagement of rack-teeth 56, on the surface of the sleeve 13, with a spur gear 55. The spur gear 55 is mounted freely on a shaft which carries a worm-wheel 57 driven at a pre-determined speed by an electric motor 59. The wheel 57 and gear 55 are connected by a roller clutch 64 such that, when the gear 55 reaches the speed of the wheel 57, no further increase in speed is possible, but below that speed, and in the reverse direction, no limitation is imposed. Thus, when the wheel contacts the work, the feeding-speed of the wheel is limited by the speed of cutting, the pressure being determined by the pistons 32. When the wheel has been fed to depth, a limit switch 66 is actuated and stops the motor 59, thus preventing any further feed. If necessary, a delay relay may then allow a dwell before the valve 36 is actuated to withdraw the wheel. Automatic means for moving the plate 14 vertically may be provided combined with means for preventing movement of the sleeve 13 until the wheel is well clear of the work. The pneumatic feed means for the sleeve 13 may be replaced by hydraulic or spring means and the sleeve may be retracted mechanically.
