Title: Improvements in elevators
IPC: B65G47/00
Filed: 1952-07-18
Abstract: 731,825. Endless bucket elevators. BEECH, A. S., and FOUNDRY EQUIPMENT, Ltd. July 18, 1952 [May 7, 1952], No. 11553/52. Class 78 (1). In a bucket elevator for material such as moulding sand which is apt to stick to the buckets when the latter are discharging their contents, each bucket has a flap 9, Fig. 1, in the form of a false bottom hinged at 10 and so arranged that when the bucket is being inverted the flap swings under the combined action of gravity and centrifugal force until the tip of the flap is approximately in line with the front edge of the bucket and completes the discharge of the contents of the bucket. A weight 13 is attached to the flap 9, whilst a stop 14 on the bucket restricts the movement of the flap. In Fig. 2, the bucket has no bottom other than the flap 9. This rests at one end on a rim 15 formed on the front of the bucket whilst during the descent of the bucket the flap is retained within the bucket by its tailpiece 16 engaging a stop 17 on the bucket.

Patent GB-570649-A (GB)
Title: Improved compositions comprising plasticized polyamides and articles derived therefrom
IPC: C08K5/13
Filed: 1941-09-19
Abstract: Impregnating and coating compositions comprise synthetic linear polyamides plasticized with a polyphenol containing at least two hydroxyphenyl nuclei separated by a radical containing a chain of at least 6 carbon atoms which chain may also contain oxygen or other atoms contiguous with the carbon atoms, e.g. the diphenylol prepared by heating phenol with 1.12 octadecanediol; or phenolated fatty acids derived from phenols and a fatty oil containing unsaturated or free hydroxyl groups, e.g. glycerol trioleate, castor oil, hydrogenated castor oil, olive oil.  The composition may be made by dissolving the polyamide and the polyphenol in a common solvent, e.g. lower fatty acids, methanol-calcium chloride, chloroform methanol, or ethanol-water mixtures.  Two compositions are made up from the interpolymer derived from hexamethylene adipate, caprolactam and decamethylene diammonium adipate (40 : 30 : 30 ratio) comprising: <TABS:0570649/IV/1> Two coats of composition A are applied to a black sateen fabric and dried and four coats of composition B added.  The fabric is skivered on a roll at 160 DEG  F. and then 9 additional coats of composition B are applied; the coating is then washed with ethanol, methylcellosolve; and water, a flexible leather-like fabric being obtained.  Additional plasticizers specified are alcohols-methanol, propanol, isobutanol, benzyl alcohol and cyclohexanol, hexamethyleneglycol, glycerol; dibutyl phthalate, tricresyl phosphate; monomeric amides boiling over 220 DEG  C.; cycloketones; sulphonamides; esters of dibasic carboxylic acids. The polyphenols containing at least two hydroxyphenyl nuclei separated by a chain of at least 6 carbon atoms, which chain may contain also oxygen or other atoms contiguous with the carbon atoms in the phenyl nuclei are prepared by reacting the corresponding diol with excess phenol in the presence of a dehydrating agent such as zinc chloride or sulphuric acid, or a dehydrating catalyst, e.g. boron trifluoride or hydrogen fluoride. Examples of polyphenols of the type described are 1 : 10-di-(p-hydroxyphenyl); decane 1 : 12 - di - (p-hydroxyphenyl)-octadecane; 2 : 10 - di - (hydroxyphenyl) - octa - decane; 2 : 12 - di - (hydroxyphenyl) - tridecane.

A valve suitable for controlling the flow of liquids at low temperatures, e.g. liquefied gases, consists of a hollow member 8 mounted in a tube 5 and formed with a surface 9 for cooperation with a tubular closure member 12 which is carried by a double-walled tube 13. The tube 13 is slidable in the tube 5 and also in a ferrule 14 to which the tube 5 and an outer tube 3 are fixed. A further outer tube 31 is engaged over a portion of the tube 3 and carries a flange 33 by which it is secured to a similar flange fixed to the tube 3. At its other end the tube 31 is flanged at 32 for attachment to a pipe that terminates in a ferrule 16 in which the tube 13 is slidable. The tube 13 is movable against a spring 27 to open the valve by pressure applied through a connection 26 to a piston 28 which is soldered to the tube 13 and is slidable in the tube 31. A second fluid connection to a point between the piston 28 and the ferrule 16 may be provided in place of the spring, or the valve may be closed mechanically or electromagnetically.
