Filed: 1926-02-09
Abstract: 258,779. Fitzpatrick, H. D., (Marquette Tool & Manufacturing Co.) Feb. 9, 1926. Cupping.-A work-holder for a cupping-press comprises a ring 14 supported by pillars 16 which rest on a plate 17 carried by a piston rod 22. A piston 21 secured to the rod, works in a cylinder 19 to which fluid-pressure may be admitted through pipes 25, 27. The pipe 25 is in communication with a pipe 26 connected to a threeway valve-box 28 in which is housed a valve 32 actuated by adjustable tappets 35. 36 on a rod 34 moving with the press-head. The upper part of the cylinder 19 is connected to the atmosphere at 31 during the operative stroke of the die 12, the pressure in the lower part of the cylinder meanwhile holding the blank 15. Towards the end of the downstroke, the actuation of the valve 32 places the two ends of the cylinder in communication, and owing to the difference in theeffective areas of the piston on the two sides, the work-holder is caused to rise more gradually than the upper die, this upward movement of the work-holder serving to strip the cupped blank from the lower die 13.

Abstract: 676,507. Control of A.C. motors. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Feb. 16, 1951.. [Feb. 22, 1950] No. 3787/51. Class 38 (iii). In order that the speed of an asynchronous motor 3 may be rendered substantially independent of the load theA.C. coils of a saturable reactor 1 are connected in the primary circuit of the motor. One D.C. control winding 7 of the reactor is energised in accordance with the motor primary current through current transformer 4 and rectifier 6 the other reactor control winding 11 being excited proportionately to the motor primary voltage through rectifier 9. The winding 11 is arranged so that its magnetic field opposes that of the winding 7. Adjustable regulating resistors 8, 10, (one of which can be omitted) may be provided. In Fig. 3 (not shown) the motor rotor winding is connected to a control winding of the reactor through a rectifier and series and parallel regulating resistors, so that the control winding is energized in accordance with the motor secondary current. An increase of motor torque produces larger primary and secondary currents together with increased excitation of the winding 7, so that a higher voltage is applied to the motor whereupon the ampere-turns of the windings 7, 11, are re-balanced, the speed of the motor remaining substantially unchanged over a wide range. The set speed may be adjusted by means of the variable resistors in the circuits of the control windings of the reactors.

Title: Copolymers
IPC: C08F36/20
Filed: 1942-04-01
Abstract: An infusible and insoluble polymer is prepared by polymerizing a mixture of a fusible heat-convertible polymer of an organic oxygen compound containing at least two polymerizable groups and another compound containing at least one of said groups.  The fusible polymers may be prepared as described in Specifications 536,807, 540,938 and 540,939.  In addition, the polymers made from mono or diisopropenyl carbonate, phthalate, crotonate, maleate, acrylate, malonate or oxalate may be used.  Further, the fusible polymer may be prepared as described in Specifications 578,266 and 578,267.  The other compound may be vinyl acetate, vinyl chloride, acrylic or a -substituted acrylic acids, methyl, ethyl, propyl, butyl, amyl and lauryl acrylates, methacrylates ethacrylates or a -chloro-acrylates glycol and glycerol monoacrylates or monomethacrylates, glycerol monochloroacrylate, resorcinol monomethacrylate; allyl or crotyl acetate, chloride, benzoate and alcohol; methallyl chloride, acetate, butyrate and benzoate; styrene, vinyl ethyl ether, ethyl allyl ether; methyl, ethyl, propyl, butyl or amyl crotonates, chlorocrotonates, cinnamates or tiglates, methyl, ethyl, propyl or butyl maleates or fumarates; monomethylallyl, monoallyl or monocrotyl phthalates, citrates, tartrates, silicates, adipates, glutarates, lactates, glycollates, suberates, succinates, phosphates, phosphites, sulphates, sulphites or sulphides; butadiene and chlorobutadiene. Mixtures of fusible, heat-convertible polymers, or such polymers incorporated in a monomer capable of forming such polymers may be further polymerized.  Preferably, the composition resulting from the polymerization of monomer is concentrated to increase the proportion of fusible polymer relative to monomer.  The further polymerization may be catalysed by oxygen, ozone or peroxides under heat, light or pressure.  The catalyst may be formed in situ by oxidizing the monomer or polymer by passing air or oxygen through their solutions. In a typical example, a solution of allyl methacrylate and benzoyl peroxide in acetone was refluxed at 63 DEG  C. for three hours. Methyl alcohol was added and the mixture added, with stirring, to a methyl alcohol-water mixture.  The precipitate of fusible polyallyl methacrylate was mixed with methyl methyacrylate and benzoyl peroxide and heated in a mould at 65 DEG  C. for 17 hours.  The product was further heated at 100 DEG  C. for eight hours to produce an insoluble material.

Title: Improvements relating to the sizing of paper fibres and the like
IPC: D21H17/60

Abstract: Paper or like fibres are wax-sized by adding wax, e.g. scale wax, to an aqueous pulp heated above the melting point of the wax, e.g. 160 deg. F, mixing, and then fixing the wax on the fibres by adding an amino amide having the general formula:-R1CO (NH CH2 CH2) n NHR2, where R1 is at least a 7-carbon aliphatic chain; R2 is H or a 1-3 carbon alkylol group and n is 2 or 3 when R2 is H or 1.2 or 3 when R2 is alkylol.  An amino amide, e.g. C17H35CONHC2H4NHC2H4OH, made by condensing hydrogenated soyabean oil with ethanolethylene diamine, may be used.  A water-soluble quarternary derivative of the amino amide having additional radicles R3 and Z may also be used; R3 being H or a 1-3 carbon alkyl group; Z an acid residue.  Alternatively, the corresponding glyoxalidines may be used.  The amount of amino amide may be 3 per cent of the weight of wax, or over, and sufficient acetic acid or a 1-3 carbon monocarboxylic acid may be added to attain pH6.  Specification 524,847 is referred to.

Title: Improvements in the destructive hydrogenation of carbonaceous materials and in the recovery of oils from the residues of said treatments
IPC: C10G1/08
Filed: 1934-02-10
Abstract: The destructive hydrogenation of carbonaceous materials is carried out under such conditions of time &c., that the solid constituents of the residue are of relatively uniform and small size, i.e. below 10m , and the residue is centrifuged continuously preferably with the aid of a diluent.  The solid material is preferably pretreated with acid, pasted with oil, and hydrogenated in presence of finely divided catalysts the residues being recycled to the reaction space until the required uniformity of size is obtained.  The material is treated with acid, or substances forming acids under the reaction conditions, e.g. halides until the basic constituents of the coal &c. are neutralized.  An excess of acid may be used.  The materials are passed through a preheater into the reaction chamber and thence into a separator maintained at reaction temperature or up to 100 DEG  C. therebelow.  The solid residues which are usually of 1--5m  diameter are separated from the oil by centrifuging, preferably after mixing with solid absorbents, e.g. coal dust, clay shreds, &c., in disc centrifuges with a conical inner wall.
