IPC: B23B5/00
Filed: 1940-02-19
Abstract: 538,768. Lathes. HEPBURN, J. T. Feb. 19, 1940, No. 3160. [Class 83 (iii)] A lathe particularly for recessing the base of a shell and forming the riveting rib thereon comprises a base plate, secured to the bed and carrying a saddle which is moved longitudinally by pneumatically-operated, hydraulically-controlled cylinders and pistons arranged in tandem, the movement being determined by gauging means mounted on one of the cylinders. End working tools 17, 18 are employed for cutting the recess and rib respectively, and similar tools 17A, 18A perform the finishing operations. A base 19 secured to the bed carries a longitudinally-moving saddle 20 actuated by a tandem arrangement of cylinders 21, 22, the former being a hydraulic control cylinder and the latter a pneumatic operating cylinder, the cylinders acting in the manner described in Specification 510,994. The end of the hydraulic cylinder is screwed to receive a hand wheel 28 and a nut 29 is screwed over the piston rod. The nut carries a pivoted depth gauge 30 which may be interposed between the hand wheel and nut. The depth gauge is used as a setting means and is swung aside when the recess is cut in the work. The hand wheel is graduated on its periphery in thousandths of an inch and is turned to permit a finishing cut of a few thousandths. The tool positioning mechanism consists of a bracket 31A secured to the saddle and carrying a rod 32A, Fig. 3, threaded at 31 and fitted with a stop disc 32. The rod 32A is slotted to receive a bar 38 which is secured to a gauge 37 and is movable by a gauge rod 39 which is adjusted from a graduated disc 40 operated from a handle 43 through a friction pad 45. The roughing tools are positioned by engagement of screw 33 with a movable stop 47. When this stop is raised the tool holder can be moved so that it contacts the gauge 37, thereby positioning the finishing tools The transverse movements to give the roughing, finishing and withdrawn positions of the tool holder are effected by a pneumatic cylinder 48, Fig. 2. A stop 50 limits the withdrawal movement of the tool-holder to allow chucking and removal of the work.

Title: Hydroxylation of olefinic compounds
IPC: C07C31/18
Filed: 1948-02-05
Abstract: Compounds having at least two hydroxyl groups attached to two adjacent carbon atoms are manufactured by the hydroxylation of compounds with one olefinic link with aqueous hydrogen peroxide in the presence of a catalyst, initially in the form of tungsten oxide and/or molybdenum oxide, at a temperature between 50 DEG  and 100 DEG C.  The reaction may be carried out with or without the presence of an inert organic water-miscible diluent, e.g. acetone, tertiary butanol, dioxane or acetic acid.  Olefinic compounds which may be used as starting materials are hydrocarbons such as n-oct-1-ene cyclohexene, but-1-ene, 2 : 4 : 4-trimethyl-pent-1-ene, 2 : 4 : 4-trimethyl-pent-2-ene and 4-ethyl-pent-2-ene; alcohols such as allyl alcohol, crotyl alcohol, but-3-en-2-ol, pent-3-en-2-ol and 4-methyl-pent-4-en-2-ol and olefinic acids such as acrylic acid, crotonic acid and maleic acid.  Olefinic aldehydes such as acrolein and crotonaldehyde may also be hydroxylated in this way but they may be oxidized simultaneously to the corresponding acids.  When acetic acid is used as a diluent it is desirable to react it first with the hydrogen peroxide, dissolve the tungstic and/or molybdic oxide therein and then react the mixture with the olefinic compound.  In the examples: (a) glycerol is prepared from allyl alcohol; (b) butane-1,2,3-triol is prepared from crotyl alcohol; (c) 1.2-dihydroxybutyric acid is prepared from crotonic acid; (d) octane-1.2-diol is prepared from n-oct-1-ene; (e) trans-cyclohexane-1.2-diol is prepared from 3-ethyl-pent-2-ene by the action of aqueous hydrogen peroxide in the presence of a catalyst as described above.  Specification 508,526 is referred to.

Convention date, Feb. 14, 1931. [Class 110 (iii).] A distributer for hydraulic reversing turbines comprises a series of guide vanes 1 each pair held axially by a flange 3 on which is cut a toothed wheel 4, each wheel 4 being connected to other guide vanes by gears so that the whole system of blades is rotated simultaneously. Means comprising two screw systems working on different pitches cause either a rotation of the blades or a translational movement of the system. Each pair of guide blades 1 has a screw thread 8 meshing with a thread of a hollow shaft 9. A screwed rod 10, secured to the vanes by a square end 10a and a flange 10c, meshes with threads on a hollow shaft 11. The screw systems 8-9 and 10-11 have different pitches. Fig. 2 illustrates the movements of translation or rotation. If relative movement of threads 8-9 is a and that of threads 10-11 is b, the resultant is c, a movement of translation without rotation of the vanes. If 8-9 moves through a and 10-11 through d, the resultant motion is e, a rotational one of the vanes, without axial movement. A servomotor has gearwheels 13, 14 on shafts 15, 9 so that the latter is driven at a uniform speed. Gears 16, 18 of different size are loosely mounted on the shaft 15 and driven thereby when clutched by claw teeth 23, 24 on a sliding clutch 22 which is keyed to the shaft 15. Gears 17, 19 are keyed to shaft 20, which is an extension of the hollow shaft 11. A servomotor has ports 25 of its cylinder connected to a suitable valve which controls the admission of pressure fluid from any convenient source to one or other of the ports 25.

Patent GB-413041-A (GB)
Title: An improved method and apparatus for extracting fats, oils and the like
IPC: C11B1/10
Filed: 1933-02-03
Abstract: Fats, oils, waxes and resins are extracted from raw materials containing them by treatment in an extractor with solvent vapours under pressure and applying to the vapour exit of the extractor, suction generated by a low pressure produced by condensation of the vapours, and by an induced draught at the end of the apparatus. Solvent such as trichlorethylene is pumped from a tank 6 through a heater H in which vapours are generated under a pressure of about 10 lbs. controlled by the temperature of superheated steam passing through the coils 9.  The pressure of the solvent vapour in the exit pipe 13 is regulated by a valve 51 connected to a throttle TV in the steam supply pipe 10.  Solvent vapours from the heater H pass to an extractor E<1> either through a pipe 14 and inlets 15, or through a pipe 16 and a cupped perforated pipe 4.  The pipe 4 may be surrounded by a flat iron spiral coil supported on the grating.  The solvent vapours rise through the raw material supported on a grating 1, and are reheated by a steam coil 48 and pass through a jacket 18, and pipe 21 to a condenser C<1> or to a second similar extractor E<2> also containing raw material.  Vapours pass around a jacket 18 and through a pipe 24 to a condenser C<2>, from which the liquid solvent flows through a pipe 35 to a separating chamber R surmounted <PICT:0413041/III/1> by a condenser C<3>.  Cooling water passes through the condenser C<3> and a pipe 26 to condensers C<1>, C<2> from which it flows through a pipe 28 connected to a vertical pipe 30 open at its upper end to the atmosphere.  The vertical pipe is surrounded by a second pipe 33 forming an air space 34, which is connected through a washer W with the vapour space in the condensers. The water issuing from the lower end of the pipe 30 produces an injector effort drawing vapours from the condensers to the washer W containing porous plates 40 in which they are treated with a shower of water removing the solvent, and the mixed liquids flow through the condenser C<3> and a funnel 35<c> to the separating chamber R.  The lower layer of solvent is pumped through a pipe 42 to the solvent tank 6 and the supernatant layer of water is discharged through a pipe 35<a>.  In operation, the extractors are charged with the raw material, and vapours are first admitted through inlets 15 and later through the perforated pipe 4.  The extracted fat containing solvent flows downwards to the lower part of the chamber where it is heated by a steam coil 45.  Solvent is thereby driven off and the extracted fat is drawn off through a cock V<13>.  The raw materials may be charged into perforated buckets having a central vapour inlet tube at the bottom, and these buckets are then stacked in the extractors. The separating chamber R may be adapted for use with solvents lighter than water.  The induced draught at the terminal of the apparatus may be produced by a rotary vacuum pump having a water seal.
