Abstract: 793,311. Stuffing-box substitutes. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., FARRER, C. O., and PLEWS, C. March 23, 1956 [March 25, 1955], No. 8859/55. Class 122 (5). An adjustable gland comprises a body 15, a plurality of sealing members 22 in spaced angular relation, each radially movable in relation to the body in a guideway 20 formed therein, and means operable from outside the body to move the sealing members 22 simultaneously inwards or outwards.. The inner ends of the sealing members are shaped so that in their inner position they form a seal of small diameter, e.g. around the pull-wire 13 of a cable 11 undergoing vulcanization in a steam chamber 10, and in their outer position they form a seal around the cable itself as it is drawn through the aperture 24 in the body 15. The sealing members 22 are urged outwardly by springs 33 and inwardly by the rotation of an annulus 30 surrounding the body 15, on the inner face of which cam surfaces 35 control the radial movement through pins 36 on the stems 27 of the sealing members 22. The latter may be in two or more groups arranged in series, the radial axes of each group bisecting the angle between the axes of adjacent groups, to provide overlapping seals. Such seals may be employed both at entry and exit ends of the steam chamber. Adjustment of the seals, to increase or decrease the working diameter, may be manually or automatically effected. For automatic adjustment a tell-tale 38 on the pullwire may be employed in a relay-operated circuit to start a motor arranged to move the operating annulus in the required manner.

Title: Cam roller self-energizing disc brake
IPC: F16D55/14
Filed: 1959-03-19
Abstract: 855,722. Disc brakes. GOODYEAR TIRE & RUBBER CO. March 19, 1959 [April 24, 1958], No. 9544/59. Class 103 (1). In a disc brake comprising a housing 1 with a pair of stationary, axially spaced, circular, opposed and radially-directed pressure plates 2, 3 a rotary member 5 is mounted on an axis coincident to the axis of the surfaces and carries a pair of friction discs 6, 7 having mounted thereon a pair of pressure plates 9, 10 provided. with a plurality of elliptical cam rollers 18 circumferentially spaced between the pressure plates and means for effecting relative rotation between the pressure plates to cause camming action of the rollers to move the plates against the discs and the discs against the surfaces to effect braking action. In operation, when an hydraulic cylinder (not shown) is operated, relative rotation of the pressure plates 9, 10 is caused through toggle links (not shown) thereby causing the cam rollers 18 to roll between the plates 9 and 10; gear teeth 21 being provided on the periphery of the rollers which co-operate with gear teeth 22, 23 on the pressure plates 9, 10. As shown in Fig. 3, the rollers 18 move in the direction of presenting the major axis or some portion thereof between the plates 9, 10, thereby to move the pressure plates 9, 10 into engagement with friction discs 6, 7 and to move the friction discs against the pressure faces 2, 3 of the housing to apply the brake. The pressure of plates 9, 10 against the friction discs tends to rotate the pressure plates in the same direction as the friction discs for a limited extent until the pressure plate is arrested by a fixed abutment (not shown) against rotation and at a specific point relative to the housing while allowing limited arcuate rotation of the pressure plate, the latter plate being urged to rotate with its adjacent friction disc so as to cam the rollers between the pressure plates and thereby achieve a self-energizing braking action.

Patent GB-456061-A (GB)
Title: Improvements in the manufacture of artificial threads or the like
IPC: D01F2/06
Filed: 1935-03-28
Abstract: In manufacturing threads, films, or the like from viscose, the viscose is ripened as described in the parent Specification to an unusually high degree (corresponding with a salt point of 0,1--0,2 or lower) and directly after coagulation the product is subjected to tension whilst in a water bath or a strongly diluted solution of an electrolyte, reversion being completed only after the application of tension.  Filaments obtained by this process have a substantially cylindrical and very uniform cross-section.  Coagulation may be effected in water or dilute electrolyte solutions and advantageously the spinning bath contains just sufficient electrolyte to prevent the individual filaments from adhering to one another.  Tension may be applied by an angular path in the spinning bath, substantial stretching being avoided.  Products made according to the invention may be after-treated as described in Specification 424,229 and in this way beautifully crimped wool-like threads may be obtained.  In an example viscose of an unusually high degree of ripeness is spun as described in the parent Specification through a nozzle with 90 perforations, each 0,8 mm. wide into a funnel 55 cms. long, the speed of draft being 50 metres per minute and the precipitating bath being water at 22 DEG  C.  The thread and precipitating water pass into a vessel into which acid is introduced drop by drop so that the liquid has a pH of approximately 2.  After entering the bath and before reversion is completed, the threads are tensioned by passage over rods and are finally wound on a reel.  The threads have an individual titer of 3,5, a dry tenacity of 2,5--2,6 grams per denier, a wet tenacity of 1,8--1,9 grams per denier, a dry extension of 15,3 per cent and a wet extension of 16,2 per cent.

Abstract: 492,056. Roofs. KING, D. M. April 6, 1937, No. 9783. [Class 20 (iv)] Relates to a roof structure which comprises valley girders 10, tie beams 12 extending transversely of the girders, and rafters 14 adapted to carry the roof covering, and is supported at a plurality of points by vertical stanchions 11. According to the invention, the valley girders 10 and tie beams 12 are so disposed with respect to each other that one or the other may constitute unobstructed trackways or rails, the stanchions 11 being so located with respect to the structure that they do not directly underlie any tie beam or valley girder which serves as a trackway or rail. In the construction shown in Figs. 1 and 2, the abutting ends of two tie beams 12 which are to serve as an unobstructed trackway are secured by means of a plate 13 and angle-irons 131 beneath a valley girder 10 which is supported by vertical stanchions 11. Rafters 14, which may each comprise a pair of angle-irons disposed back to back, are connected to the valley girder 11 or plate 13. In a modification the tie beams 12 are supported beneath the valley girder by a pair of plates disposed on opposite sides of the girder. In the construction shown in Fig. 4, the stanchions 11 directly support the tie beams 12, and the valley girders 10, which constitute the unobstructed trackways, are connected beneath the tie beams 12 by a continuous girder 17 or a plurality of spaced members 17. The rafters 14 are secured to the tie beams 12 by plates 16. The trackways, disposed either singly or in pairs, are adapted to carry cranes, conveyer trollies or the like. The construction permits a pipe 15 to be led from one roof bay to the next without bending the pipe out of its normal horizontal plane.

Patent GB-913750-A (GB)
Title: Tobacco product
IPC: A24B15/12
Filed: 1960-03-21
Abstract: A tobacco sheet or smoking mixture is formed from ground tobacco mixed with a water-insoluble adhesive and a plasticizer from a group consisting of polyesters, prepared by condensing a lower polyethylene glycol or glycerol with an aliphatic acid containing a straight chain of from six to ten carbon atoms, aminoethyl phenols, hydroxymethyl phenols, or similar bis-phenols. Adhesives mentioned include cellulose acetate and its esters, and cellulose ethers such as methylcellulose, and the adhesive is dissolved in an organic solvent, such as methanol, isopropyl alcohol, benzene, toluene, chloroform or methyl butynol, before mixing with the ground tobacco.  A first class of plasticizer comprises a condensation product of a lower polyethylene glycol or glycerol with an aliphatic acid containing a straight chain of from six to ten carbon atoms.  The lower polyethylene group includes ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, pentaethylene glycol and mixtures thereof, the preferred substance being tetraethylene glycol. These substances are reacted with acids such as adipic, pimelic, suberic, azelaic or selacic.  In a specific example, a plasticizer solution was prepared from a mixture of adipic acid, azalaid acid and tetraethylene glycol dissolved in benzene, which was treated with concentrated sulphuric acid as catalyst and refluxed in a flask for 3.5 hours, after which the benzene solution of the polyester plasticizer was separated from the acid.  This plasticizer was added to a mixture of fine ground tobacco containing cellulose acetate dissolved in acetone.  The thick slurry after mixing was cast into sheets and the solvent evaporated; the resultant sheet was suitable to produce wrappers for cigars.  The second class of plasticizer consists of phenolic compounds or bis-phenols which contain one or more substituents selected from the following groups: hydroxymethyl, dialkylaminomethyl, cyclic aminomethyl or alkyl.  In one example the sheet was prepared as above with the plastcizer consisting of 2,4,6-tris-(dimethylaminomethyl)phenol.  In a second example, phenol was mixed with morpholine, formaldehyde and methanol, cooled, and extracted with benzene to produce 2,4,6-tris-(morpholinomethyl)phenol.  The ground tobacco was mixed with this plasticizer, dissolved in benzene, and with ethylcellulose dissolved in acetone and the slurry cast into a sheet. Alternatively, the plasticizer and adhesive are formed into a sheet which is subsequently coated with the fine tobacco. Other plasticizers mentioned are 4,41-isopropylidene-bis-phenol reacted with dimethylamine and formaldehyde and 2,4,6-trimethylolphenol.
