Abstract: 1,213,642. Electromagnetically - releasable brakes. ELLISTON, EVANS & JACKSON Ltd. 26 Jan., 1968 [3 Feb., 1967], No. 5233/67. Heading F2E. In a spring actuated, electromagnetically releasable, external shoedrum brake a pair of pivoted arms 14, 15, each carrying a pivoted brake shoe 23, 24 are adapted to be applied by spring means 53 acting upon an armature plate 27 of an electromagnet 26 to apply the braking thrust via a thrust block 38 which projects towards the adjacent brake arm 14 and engages a roller 40 carried on the pivot pin 25 between the flanges of the brake arm 14, the opposite brake arm 15 being applied through a push rod 41. The brake is adapted to be released by energization of the solenoid which attracts the armature plate 27 against the force of the spring 53. The electromagnet 26 is of generally rectangular form with two compression springs 53 located above the polepiece 54 which is left uninterrupted. The force of the springs may be adjusted by means of a bolt 56 and adjustment of the brake is also permitted by the screw connection 44 at the end of the rod 41. Alternatively, the brake may be released, when the electromagnet is de-energized, by movement of a handle 48 in a clockwise direction to move the armature plate 27 of the electromagnet against the actions of the springs 53 to release the brake. In a modification (Figs. 5 and 6, not shown) the bolts 56 are replaced by studs (58) which pass through an end plate 39 and engage against the collars 55. At their other ends the studs 58 are secured to a horizontal common bar (60) which is adjustable.

Title: Improvements in carrying out chemical reactions
IPC: C07C29/16
Filed: 1954-02-23
Abstract: <PICT:0755650/IV(a)/1> Butanol and isobutyraldehyde are formed when propylene, which is sprayed through pipe 4 into high-pressure or temperature reaction vessel 1, reacts with a mixture of carbon monoxide, hydrogen and a small amount of inert gas admitted through pipe 3.  A catalytic solution of a cobalt salt is also admitted through this pipe.  The bulk of the reaction mixture leaves the vessel 1 at the top and returns to the lower part of the vessel through the pipe 7, the circulation being effected solely by convection.  The mixture flowing through pipe 7 can be degassed by using pipe 8 and a part of the product can be removed from calming zone 2 by pipe 9. Temperatures used are from 180 DEG  to 200 DEG  C. Propionic acid can similarly be prepared from ethylene and carbon monoxide using a nickel propionate catalyst at a temperature of 295 DEG  C.  The invention is also applicable to other olefines and to the reactions of olefines and carbon monoxide, with water, carboxylic acids and alcohols to form acids, anhydrides, and esters respectively.ALSO:In a high temperature, pressurized reaction, the starting materials are led upwardly through a reaction chamber, with or without a catalyst, and the bulk of the liquid product is returned to a lower part, preferably the lowest part of the chamber.  The circulatory streaming is maintained solely by the difference in density, caused by a temperature difference between the chamber and the return pipe.  Temperature control is thereby maintained in such reactions as the oxo reaction, i.e. reactions between olefines and carbon monoxide and water and carbonylations of carboxylic acids or alcohols to form other acids, anhydrides or esters.

Title: Improvements in unidirectional driving devices
IPC: F16D41/07
Filed: 1926-02-26
Abstract: 271,572. Constantinesco, G. Feb. 26, 1926. Ratchet gearing.-In friction ratchet gearing, a high-frequency oscillator 4 (or 2) and a rotor 2 (or 4) form concentric races for balls or rollers 6, between which and one or both races are introduced thin, elastically-influenced metal or other strips 8, adapted to be nipped between the rollers &c. and the race or races on.the forward movement. As shown in Fig. 3. a thin, sharp-edged hard steel blade 8 coact with each roller 6 and the rotor 2, and has soldered &c. to its rear end a shoulder 9, which may be of different material. The shoulder and a wall of a metal tray 7, Fig. 3, bearing on adjacent rollers, form abutments for a pair of transversely-arranged bowed leaf springs 10. In anotheir form, the trays and springs are omitted, and blades of S or Z section contact with the sides of adjacent rollers, while their sharp edges are forced between one roller and the rotor and between the adjacent roller and the oscillator by the inherent elasticity of the blades. As shown in Fig. 6, the blades 8 are anchored to bars 11, shaped to act as distance-pieces, between the rollers, and are crumpled so that their edges are forced between the rollers and the oscillator or rotor. In a modification, the bars 11 sre situated as shown in Fig. 7. The blades themselves may, however, be bent or folded at their inactive ends to bear. on the sides of the rollers, the bars being dispensed with. Fig 10 shows a reversible device, wherein double-ended blades 8 are carried by a displaceable cage 13, the rollers 6 being spaced by a second cage 12. It is stated that the thickness of metal strips should be approximately one-hundredth of the roller diameter, where they operate at one end only, or one-two-hundredth where they operate simultaneously at both ends, these thicknesses 'being increased respectively by the amount and half the amount of any initial play between the rollers and races 2, 4. Fibre strips should be of greater thickness. An efficient supply of thin lubricant, such as a mixture of petroleum lamp oil and ordinary mineral oil, is essential.

Title: Improvement in and relating to the production of aqueous solutions of cellulose
IPC: C08B1/00
Filed: 1943-04-07
Abstract: Stable solutions of cellulose suitable for coating textile materials or for the formation of films or filaments are obtained by dissolving modified or unmodified cellulose in an aqueous solution of sodium zincate containing an excess of sodium hydroxide.  The cellulose solution is prepared at a temperature between about 5 DEG  C. and the temperature of crystallization of an inorganic component of the solution, and promptly warmed, preferably to 15-30 DEG  C., to minimize the tendency to gelation on standing.  The solution may be subsequently aged to reduce its viscosity.  The solution of sodium zincate which is prepared by dissolving zinc oxide in an excess of an aqueous solution of sodium hydroxide, is pre-cooled before the cellulose is added, or alternatively, cellulose may be mixed with the sodium zincate solution and the mixture subsequently cooled to effect a solution. The source of cellulose employed may be cotton linters, wood pulp, paper, &c., or modified cellulose such as rayon, oxycellulose, or regenerated cellulose film waste.  Cellulose may be regenerated from the solution by warming to 50 DEG  C. or above, or by the addition of water, an acid such as sulphuric acid, a salt, e.g. aluminium sulphate, sodium sulphate, calcium chloride or sodium chloride, a mixture of an acid and a salt, e.g. sulphuric acid and sodium sulphate, potassium sulphate, zinc sulphate, &c., or a solution of an alkali metal hydroxide.  Numerous examples are given.
