Title: Improvements in the control of hydraulic forging presses
IPC: B30B15/16
Filed: 1959-04-23
Abstract: 857,485. Forging presses. SCHLOEMANN A.G. April 23, 1959 [May 12, 1958], No. 13829/59. Class 83 (4). [Also in Group XXIX] An hydraulic forging press has its stroke controlled by a control member 14, actuated by sliding cross-head 4 of the press, which produces in a phase detector circuit 20 a voltage vector proportional to the position of the crosshead, which vector is compared with a constant voltage vector and furnishes according to the position of the cross-head with relation to a predetermined mid-stroke position, a positive or negative control voltage which acts through a reversing relay 24 to energize through a time delay 26 an electromagnet 35 controlling a pressure water-supply valve 38 or to energize directly an electromagnet 28 controlling a pressure water-outlet valve 31. The crosshead 4 is moved downwardly by pressure water admitted to a main cylinder 2 connected through pipe 7 to a distributer 8, and is retracted by return cylinders 5 connected continuously through pipe 6 with an hydraulic accumulator. The cross-head carries a rack 10 meshing with a pinion 11 connected through electromagnetic clutch 13 with an inductive remote control member 14. In operation the distributer 8, controlled manually or remotely from a control desk 47, first connects pipe 7 with a main manually-controlled supply pipe 50 whereby the press performs an initial forging stroke. The distributer is then moved to a finish forging position whereby it connects pipe 7 with a control valve unit 39 containing the valves 38, 31 and having a pressure water-supply pipe 40 and an exhaust pipe 41. Simultaneously clutch 13 is energized whereby member 14 passes a voltage dependent upon the position of the cross-head to the phase detector circuit 20 which also receives a constant comparative voltage through conductors 51 from main supply 52. Any resulting positive or negative output voltage from the circuit 22 passes through conductors 22 to the reversing relay 24. When the cross-head is rising the relay 24 acts through time delay 26 to stop the cross-head at a definite height and after a delay, which is adjustable by a potentiometer 46 on the desk 47, it energizes a solenoid-actuated pilot valve 35, 36 which causes piston 37 to open the valve 38 and initiate the next downstroke of the cross-head. Subsequently the detector circuit 20 passes an output voltage of opposite sign to the relay 24 which energizes pilot valve 28, 29 to open the outlet valve 31 causing the crosshead to be raised by the return cylinders 5. The mid-stroke position of the cross-head is adjustable by a remote-control member 16 adjusted by a control motor 17 and connected electrically to the member 14.

Patent GB-762144-A (GB)
Title: Monocrystalline strontium titanate
Inventor: MERKER LEON
IPC: C30B29/26
Filed: 1954-05-18
Abstract: Monocrystalline strontium titanate is prepared by introducing into an oxygen hydrogen flame a powdered composition consisting of strontinum titanate and at least 0.01 per cent by weight of the titanate of an added oxidic compound of strontium, calculated as oxide, and crystallizing the melted material in the form of a boule, which may subsequently be subjected to oxidizing treatment at 650 to 1700 DEG C.  Amounts as high as 20 per cent of strontium oxide or higher may be employed but the preferred amount is 0.1 to 1 per cent, and very little of such strontium oxide remains in the boule since it volatilizes in the flame.  The strontium titanate employed may be prepared by reacting strontium chloride with titanium oxalate to precipitate strontium titanium oxalate which on heating to above 500 DEG C. forms strontium titanate.  The oxidic strontium compound may be added to the titanate by dry mixing or preferably by adding the strontium oxide as a powder, slurry or solution to the strontium titanium oxalate prior to conversion to strontium titanate.  On fusion of the powdered materials in an oxygen hydrogen flame at 2080 to 2150 DEG C. black boules are obtained which on subjecting to heat treatment in an oxidizing atmosphere become colourless and suitable for forming gems or lenses and prisms.  The material has a refractive index of 2.4 and a reciprocal dispersion of about 13.  Specification 762,142 is referred to.

Title: Polymeric materials
IPC: C08F20/62
Filed: 1955-05-20
Abstract: Vinyl and allyl esters of beta,beta-dialkyl acrylic acids are prepared by the following methods: (a) in the case of vinyl esters by reaction of the acid with acetylene, or by transesterification of the acid with a vinyl ester, and (b) in the case of allyl esters by the esterification of the acid with allyl alcohol, by the transesterification of the acid with an allyl ester, or by the reaction of allyl chloride with a metallic salt of the acid.  In examples: (1) vinyl beta-beta-dimethylacrylate is prepared by ester interchange between vinyl acetate and beta-beta-dimethylacrylic acid in the presence of mercuric sulphate as a catalyst, the reaction mixture being washed with a solution of sodium bicarbonate before distilling.  The product is characterized by means of its density, boiling point and refractive index; (8) allyl beta-beta-dimethylacrylate is prepared by esterifying the acid with allyl alcohol in presence of sulphuric acid and benzene.  The product is characterized by means of its density, boiling point and refractive index; (9) vinyl methyl-3-pentene-2-oate is prepared by ester interchange between the acid and vinyl acetate.ALSO:Insoluble, infusible three-dimensional polymers are obtained by polymerizing manomeric material which includes at least one monomer of the formula <FORM:0786381/IV (a)/1> in which R1 and R2 are alkyl radicals and R3 is a group comprising an ethylenic bond of the form CH2=C<, the polymerization being carried out in two stages of temperature: (1) at a temperature less than that which would cause gelification, e.g. 100 DEG  C., thus obtaining a fusible soluble linear polymer, and (2) at a higher temperature in order to produce an insoluble, infusible polymer.  Monomers specified are vinyl and allyl senecioates, the vinyl ester of methyl-3-pentene-2-oic acid and the N-allyl amide of senecioic acid.  These compounds may be copolymerized with other monomers such as vinyl acetate, vinyl chloride, acrylic and alpha-substituted acrylic acids and their nitriles, amides and esters, e.g. methyl acrylate and methacrylate and acrylonitrile, styrene, alpha-methyl styrene, vinyl naphthalene, maleic anhydride, methyl vinyl and methyl isopropenyl ketones and vinyl alkyl ethers. The first stage of polymerization may be carried out in bulk, in solution in solvents such as benzine, or in aqueous emulsion with the acid of emulsifiers such as sulphonated diheptylsuccinate or a mixture of sodium sulphoricinoleate and a condensation product of ethylene oxide and oleyl alcohol.  Catalysts may be employed such as barium and hydrogen peroxides, ammonium and potassium persulphates, benzoyl peroxide, cumene hydroperoxide and azo-diisobutyronitrile and redox systems including reducing agents such as sodium bisulphite and thiosulphate.  Also present may be polymerization regulators such as halogenated hydrocarbons and mercaptans.  In the second stage of polymerization the polymers, after preliminary processing if desired, are subjected to a higher temperature, e.g. 100-150 DEG  C., with the addition, if required, of further quantities of catalyst.

Filed: 1960-04-27
Abstract: 885,351. Stacking sheets. WARREN CO., S. D. April 27, 1960 [May 6, 1959), No. 14803/60. Class 100(1) Apparatus for aligning rectangular sheets of paper or the like which are successively deposited on a pile, comprises a pair of flat, elongated boards located at opposite sides of the pile and connected to mechanism which repeatedly moves them towards and away from positions corresponding to the opposite sides of the pile, each board carrying a device for striking the board with a sharp, sudden blow each time it reaches a position corresponding to the side of the pile. Sheets are fed from above, by means not shown, on to a pile 10, a number of inclined endless belts 14 directing the sheets forwards and downwards as they approach the pile. The front edges of the sheets are aligned against stops 18. Parallel horizontal shafts 22, 24 are journalled in bearings secured to beams 28 and have rigidly secured thereto boards 38, 40 respectively. The shaft 22 carries a crank lever 42 which is moved between and full- and dotted-line positions of Fig. 3 by means of a lever 44 controlled, by a cam 48. The cam 48 is mounted on a driven shaft 52. The shaft 24 is oscillated in a similar manner and in synchronizm with the shaft 22. Each of the boards 38, 40 has two solenoids 74 mounted thereon, the armatures of which strike a portion of the solenoid housing adjacent to the boards when the solenoids are energized. The solenoids are controlled by a cam 118 on the shaft 52 which closes a switch 114 in the solenoid circuits at the instant that the boards 38, 40 engage the pile 10. The sharp rap thus produced on the boards by the solenoids assists in squaring-up the pile. The boards 38, 40 are perforated at 120, the holes having flared mouths on the inner sides of the boards, so as to minimize air currents caused by their movement. The cam 48 is so shaped that the boards move rapidly outwards and more slowly inwards. The solenoids may be replaced by hammers driven by air pressure released by a valve which is opened at the desired instant by mechanical or electrical means, or by hammers tripped mechanically.
