Title: Improvements in and relating to bottle closing machines
IPC: B67B1/08
Filed: 1922-06-30
Abstract: 198,579. Gabell, C. D. June 30, 1922. Stoppering. - Apparatus for fastening the stoppers of swing- stoppered bottles while in the sterilising-oven comprises flexible devices to engage and operate the lever wires of the stoppers with means for operating the devices from outside the oven. The bottles 1, Fig. 6, are placed in rows in the oven, being held in position by partitions 2a in boxes 2, with the stoppers 3, Fig. 3, loosely in position and the lever wires 4 all facing in the same direction. The closing devices consist of metal strips 5 bent at their ends to form leading-edges 5a and attached to bars 6 arranged above and in line between the rows of bottles. The bars 6 are attached to a sliding frame 7, Fig.1, suspended by means of circular extensions 8 of racks 9 which can be raised and lowered by means of pinions 10 on a shaft operated through worm gearing by a handle 12. Guide-strips 13 engage the opposite sides of the bottle necks to the devices 5, and tubular bars 15 carried by a frame 14 lie upon the shoulders of the bottles. To prevent the strips 5 from lifting the bottles on raising the frame 7 after it has been lowered to fasten the stoppers, the frame 14 is held down by clips 16.

Patent GB-852130-A (GB)
Title: Separation of organic bases
Inventor: YEOMANS BERTRAM
IPC: C07D213/06
Filed: 1958-06-21
Abstract: A volatile organic base is separated from a mixture with at least one other volatile organic base of different basicity by a process comprising passing the vapours of the bases through a zone countercurrently to an aqueous acid solution and adding to the zone an aqueous solution of an alkali having a greater basicity than that of the base to be separated.  The invention may be carried out by distilling the mixture of volatile bases in a column down which the aqueous solutions of the acid and alkali are passed, the alkali solution being fed into the column at or below the feed point of the volatile organic bases.  The stronger volatile bases may then be recovered in the form of aqueous solutions of their salts from the base of the column, the weak volatile base being removed as distillate, with water, from the head of the column.  Conveniently the mixture of bases is fed into the column at about the midpoint. The aqueous acid solution preferably has a pH value below 5,0 and may be, for example, an aqueous solution of phosphoric acid, sodium hydrogen succinate, succinic acid, oxalic acid, formic acid, hydrochloric acid or sulphuric acid.  The aqueous solution of the alkali is preferably of a compound such as sodium hydroxide, potassium hydroxide or ammonia, which has a greater basicity than that of any of the volatile bases present in the mixture.  The process may be used, for example, for (a) the separation of 2-methyl-5-vinyl pyridine from 2-methyl-5-ethyl pyridine; (b) the separation of a mixture of pyridine, 3-vinyl-pyridine, 2-methyl-5-vinyl-pyridine, 3-ethyl-pyridine, a -picoline, b -picoline, 2-methyl-5-ethyl-pyridine and 2.5-lutidine, and (c) the separation of a mixture of b -picoline, g -picoline, a -picoline and 5-methyl pyrimidine.  The process may also be used for separating b -and g -picolines; 2.4-and 2.5-lutidines; o-,m- and p-toluidines; 2.3-, 3.4-, 2.6, 2.4-, 3.5- and 2,5-xylidines; and alkyl-dialkyl-and tri-alkylamines and arylamines.

Abstract: 254,884. Brown & Sons (Huddersfield), Ltd., D., Brown, F. E., and Merritt, H. E. July 17, 1925. Patent abandoned on opposition. Gear-cutting. - A pair of mating toothed bevel gears having curved teeth are produced by means of counterpart rotary cutters having profiles such as are shown in Fig. 1 and mounted with their axes substantially perpendicular to the pitch plane of an imaginary crown wheel engaging the blank and on which the blank rolls during the generation of the teeth. One cutter is used to generate the sides of a toothed space of one gear and the other similarly generates the sides of a tooth of the mating gear. The complete gear is in each case generated by indexing the blank between successive tooth cutting operations. Modifications of the straight-sided cutter profiles shown in Fig. 1 may be employed. An additional set or sets of cutting-edges may be arranged on either or both cutters so that while one tooth or space is being finished; others may be simultaneously roughed out. Instead of using rotary cutters, cutters having an oscillating movement may be employed. Abrasive wheels of similar profiles may be used in place of the cutters. Fig. 4 indicates the position of the cutters relative to the basic crown wheel.

[Also in Division G1] A temperature responsive element 6 for actuating a rotary valve in the form of a sleeve 5 controlling hot and cold water streams 1, 2 to provide a water stream at a preselected temperature, comprises a double coil of a resilient sealed metal tube filled with and prestressed by distilled water under pressure, the tube being of uniform cross-section with two substantially parallel flat walls joined by convexly curved wall sections the larger dimension of the cross-section being at least twice the smaller dimension thereof. The walls of the tube are of uniform thickness sufficient to ensure that the tube will not be deflected beyond the elastic limit of the metal of the tube when the tube is at its maximum working temperature. The curved wall sections have an internal radius not less than twice and not more than five times the wall thickness. The tube may be of phosphor-bronze or from a copper-beryllium alloy. The inner end of one coil of the tube is connected to a cap 10 coupled to the sleeve 5 and the inner end of the other coil to a spindle 8 manually rotatable by means of a knob 7. The position of the sleeve controls the relative proportions of hot and cold water passing to the interior of a cover 4 containing the element 6, and the element will maintain a constant temperature of water within the cover 4, the temperature being preselected by rotation of the knob 7. In alternative arrangements the element 6 may comprise a single coil or may be sinuous in form and may be installed in a valve having a reciprocable control member.

Abstract: 613,382. Aircraft control. WILSON, F. H. June 19, 1946, No. 18480. [Class 4] Wings 1 are each pivoted about vertical pivots 3 (preferably at the centre of pressure) so that they can be swept back from or forward of the transverse position shown by operating mechanism constructed so that the forces due to air-pressure tending to move the wings backward are opposed to each other when transmitted into the operating mechanism; the wings are so shaped that when in a forward position they each present a high-lift section and when in a backward position they present a lamina flow or low-lift section. The wing portion 26, on the inside of pivot 3, is within a fairing when the wing is extended but, when the wing is retracted, the portion 26 is moved outwardly and forwardly, providing a lift which counteracts any tendency to nosediving. The operating mechanism comprises a hydraulic cylinder 4, with a piston 6 pivoted at 17 and which is mounted in a frame 18 carrying a lever 19, to which toggle links 22, 23 for operating the wings are connected. The operation of the cylinder 4 in the central position shown moves the wings symmetrically; rear cylinders 13, 14 may be used to move the piston-rod 6 about its pivot 17 to produce an unsymmetrical position of cylinder 4 to advance one wing and retract the other.
