Title: Improvements in or relating to pressure release devices
Inventor: STEVENS ARTHUR HAROLD
Filed: 1929-06-13
Abstract: 332,362. Stevens, A. H., (Delco Products Corporation). June 13, 1929. Fluid - friction vibration-dampers. - A pressure-release valve for hydraulic apparatus is mounted on a fixed stem or support so as to provide clearance or leakage space between the valve and its supports to permit fluid to pass before the valve opens and uncovers its port or opening against the resistance of a closing spring. In the application to a vehicle shock-absorber, a piston 31 works in a cylinder 40 enclosed in a reservoir 27 bolted to the frame of a vehicle. Relative movement of the axle oscillates the spindle 50 and the lever 30 which forces the piston 31 downwards against the spring 32. Free upward movement of the piston is provided for by the one-way valve 37 but downward movement of the piston is opposed by liquid under pressure which may escape through the clearance or leakage area provided between the valve 47 and its used supporting pin 45. The valve is forced on to its seat by the strong spring 48 but may be lifted off its seat during rapid downward movement of the piston 31. The pin 45 is carried by the screwed plug 43 and its end is enlarged at 49 to prevent the valve from falling off when the unit is removed.
Patent GB-440416-A (GB)
Title: Methods of preparing higher lactones containing at least 11 carbon atoms in the lactone ring
Filed: 1934-06-21
Abstract: Lactones containing at least 11 carbon atoms in the ring are prepared by subjecting acids of the formula OH--R--COOH, where R represents an aliphatic chain of at least 10 carbon atoms, or their halides to treatment for the elimination of water or hydrogen halide respectively, said treatment being effected under heat in a highly-dilute solution.  Alternatively, the esters of the above acids are heat treated in the vapour form.  The treatment of the acids in dilute solution preferably takes place in the presence of dissolved water-eliminating catalysts such as sulphuric acid and using solvents, e.g. aromatic hydrocarbons, which form azeotropic mixtures with the eliminated water.  For the vapour-phase treatment at atmospheric pressure, only esters stable at the reaction temperature of about 200 DEG  C. may be employed, e.g. the formates and carbonates, but under reduced pressure, other esters may be employed, particularly when diluted with inert gases or vapours; a dehydrating catalyst such as titanium oxide is preferably present.  The products are useful in the perfume industry.  The examples dsscribe the preparation of the lactones of: (1) 14-hydroxytetradecane-1-carboxylic acid by adding a solution of thionyl chloride or phosphorus oxychloride in benzene to a solution of the acid in petroleum ether, or vice versa, at boiling temperature; (2) 15-hydroxypentadecane-1-carboxylic acid by adding a benzene solution of the acid and thionyl chloride to a dilute boiling benzene solution of dimethylaniline; (3) 14-hydroxytetradecane-1-carboxylic acid by the slow addition of a solution of the acid in benzene to a dilute solution of sulphuric acid in the same solvent; (4) 15-hydroxypentadecane-1-carboxylic acid by gradually adding the acid to a boiling benzene solution of benzene- or toluene-sulphonic acid; (5) 14-hydroxytetradecane-1-carboxylic acid by passing the vapour of its formic ester slowly over heated titanium dioxide; (6) hexadecene-7-o1-16-carboxylic acid and w-hydroxydecane-1-carboxylic acid by the process of (4).  In examples (1) to (4), the concentration of the acid or chloride is of the order of 0,1 per cent.  German Specification 449,217 is referred to.  The Specification as open to inspection under Sect. 91 describes also the use of functional derivatives of the acids, including their salts, and contains an example of the conversion of 14 - hydroxy - 2 methylpentadecane - 1 - carboxylic acid into its lactone by the method of (4) above.  This subject-matter does not appear in the Specification as accepted.  The formates and carbonates of the above hydroxy-acids are obtained by treating the acid with a solution of formic acid in hydrochloric acid and with chloro-formic ethyl ester respectively.

In the bending of glass sheets to a configuration having a region of sharp curvature wherein the sheet is supported over a shaping mould and heated to bending temperature, an auxiliary member is provided for supporting a portion of the glass sheet when partially bent and is mounted for movement out of engagement with the glass sheet after the mould has moved to the closed position to permit the sheet to bend to the configuration of the mould. The mould 28 comprises a centre section 29 hinged at 31 to a pair of end sections 30, the centre section comprising rails 36, 37 connected by blocks 40 to slightly lower support rails 38, 39 and the end sections rails 42 connected by blocks 44 to support rails 43. Each end section 30 has a pivot bar 32 secured thereto and supported from the frame 27 by links 33 and 35 joined by pins 34. The upper edges of the rails 42 are extended outwardly at 46 to support the edge of the flat glass sheet 20, the extension being flared and curved downwardly at the end 47. The glass is additionally supported adjacent rail 36 by pads 49 on arms 48 secured to pivot bars 32 and are lowered as the end sections 30 pivot upwardly. Adjacent the part to be curved most severely, an auxiliary rail 51 is provided between each rail 42 and its support rail 43. Each rail 51 is pivoted at 53 to one of the blocks 44 and at its other end has a downwardly extending leg 56 which is engaged by a lug 54 on a lifting member 55 secured to a block 40 of the centre section 29 so that as the mould is moved to the open position of Fig. 8, the rail 51 is lifted to the position shown. In this position it is locked by a rod 58 which extends through an opening 59 in the rail 42 to engage under the rail 51. The rod 58 is mounted between the upper ends of a pair of links 62 by a pin 64 lying in slots 65, the links 62 being centrally pivoted on a plate 63 secured to the rail 42 and being biased so that the rod 58 engages the rail 51 by a weight 67.
