Patent GB-251086-A (GB)
Title: Improvements in and relating to hydro-extractors and like centrifugal machines
IPC: B04B7/06
Filed: 1925-04-02
Abstract: 251,086. Gray, F. T., and Whitaker, Ltd., R. G. April 2, 1925. Casings; driving.-In hydro - extractors and like centrifugal machines a guard x on the casing y prevents access to the basket when the latter is rotating, the mechanism being so arranged that the initial movement of the guard from its closed position causes locking mechanism to be operated from a part of the driving mechanism to prevent any further opening movement of the guard. The basket shaft has a pulley at its lower end driven by a belt from the clutch pulley a which revolves on a fixed sleeve a' and to which may be clutched the driving pulley b. The shaft c on which the pulley b runs loosely can move axially to bring the pulley faces into engagement. This movement is obtained by a lever d which engages the end of the shaft and is operated by the handle e<3>. The spindle e<1> of the handle e<3> carries a slotted disc e<2> in interlocking relationship with another slotted disc f<2> on the spindle f carrying the cover x. Power can only be. applied to the basket when the cover is closed, as this is the only position in which the disc e<2> can pass through the slot in the disc f<2>. The spindle f carries a lever g having at its end bevelled faces g<1>, g<2> engaging corresponding bevelled faces h, h* in a locking piece h<1> carried by a tumbler h<2> swivelled on pins h<3>, h<4> at right-angles to one another. Set-screws h<5> limit the movement of the tumbler parallel to the pulleys. A spring i tends to force the friction pad h<7> on the tumbler h<2> against the face of the pulley a. When all the parts are at rest the cover x may be lifted as the lever g will be free to move with the shaft f, the nose g<2> of the lever just clearing the bevel-face h* on the locking piece h<1>. At the end of a run, power is cut off by rotation of the handle e<3>, but the bowl and pulleys continue to rotate for some time afterwards. If during this time an attempt is made to lift the cover x the lever g, is moved and the pad h<7> engages the face of the pulley a. The tumbler h<2> is carried forward and the face h* locks the lever against further movement so that the cover cannot be raised.

Filed: 1939-03-21
Abstract: 526,683. Textile lubricants. COURTAULDS, Ltd., DIAMOND, C., and STONEMAN, J. P. March 21, 1939, No. 8964. [Class 91] [Also in Group IV] Textile materials are tinted and lubricated by treating them with a liquid composition consisting of a sulphonated vegetable oil, a fugitive dyestuff, triethanolamine oleate, and a lubricating oil and substantially no water. A sulphonated vegetable oil soap may be used instead of the sulphonated vegetable oil. The lubricating oil may be a mineral or vegetable oil or a mixture of these e.g. a mineral oil and palm kernel or cocoanut or other non-drying oil. The dyestuff is one having no appreciable affinity for the textile being treated e.g. in the case of cellulose acetate threads, an acid wool dye may be used. The dyestuff may be dissolved in the sulphonated vegetable oil or fatty alcohol, heat being used if required. Triethanolamine oleate is added to this solution, preferably while hot and the composition is then diluted by the addition of lubricating oil. The mixture is then heated until most of the water is removed and a clear liquid is obtained. This is allowed to stand for some time before use, and any sediment which forms is separated. The liquid is used for marking threads for identification purposes. It may be applied by wick or roller to threads or filaments during winding or twisting. It may be applied to cellulose acetate filaments immediately after they have left the dry spinning cell. In examples, cellulose acetate threads are treated with a liquid comprising Azo Geranine, sulphonated arachis oil, triethanolamine oleate, a high boiling mineral oil, and palm kernel oil, or with a liquid comprising Disulphine Blue, " Monopol " soap (Registered Trade Mark), triethanolamine oleate, high boiling mineral oil, and palm kernel oil.

Title: Improvements in kinematograph film printing apparatus
IPC: G03B27/08
Filed: 1922-01-25
Abstract: 195,651. Correx M³vek Filmipari GÚpgyar C. Lßszl¾. Sept. 7, 1921, [Convention date]. Printing-appatatus. - Selected pictures from different sections of a film are printed by continuously feeding the negative and intermittently feeding the positive film. The apparatus may be used for copying the scenes of one actor only, or the titles only. It may also be used for determining the exposures required for the different sections, in which case the selected pictures from each section are printed with different illumination. In the form shown, as applied to the determination of the exposures for different sections, the positive film 2, Fig. 2, is passed through a pivoted gate 3 which, when released from the action of a pin 10, Figs. 2 and 3, on a disc 9, springs into contact with the negative film 1, so that the feed-pins 5 may feed both films. The disc 9 meshes with a wheel 12 on the sprocket 11 carrying the positive film, and is periodically given a momentarv axial shift by an electromagnet 14, against the action of a spring 15 so as to disengage the pin 10 from the arm 8. The electromagnet may be actuated by an arrangement of projections on the negative film co-operating with feelers as described in Specification 195,634, so that as each section of the negative film passes the gate 3, the positive film is fed with it for a period of one revolution of the disc 9. During this period a rotating disc 16, Figs. 3 and 4, on the same shaft 13 as the disc 9 cuts in successively, through contacts 20 - - 23 and 25, different resistances to vary the printing light. The pin 10 then re-engages the arm 8 and withdraws the gate 3 until the next section of the negative film arrives.

Abstract: 642,015. Locks. TRIGGS, W. W. (Schonitzer Products Co.). April 5, 1948, No. 9521. [Class 44] In a latch mechanism of the type described in Specification 501,613, the push button release means may be rendered ineffective by actuation of a key lock which allows idle operation of the push button. In the form of Fig. 2 the push button body provides a rearwardly extending cavity to receive the hemispherical head of the operating push rod E. The free end of the rod extends through a vertical slot in the bottom wall of the casing 62 and is engaged in an opening in a vertically sliding member 64. The rod is loaded by a tapered spring 61 which allows, upon movement of the slider 64, an angular displacement of the rod E, as shown. In this position, operation of the push button 60 causes the end of the rod to pass over the top of the actuating lever A and is therefore ineffective to release the latch. The slider 64 may be controlled by a barrel lock 66 having an eccentric pin 67 engaging in a transverse slot in the slider. In another form, Fig, 8, the push button 70 is prevented' from rotation and spring loaded to the projected position by a spring 71. Inside the main button slides a spring - loaded plunger 75 which carries the operating push rod E. Two pins 78 carried inside the button are, in the locked position, aligned with two holes 79 in the face of the plunger and in this position operation of the push button is ineffective to project the rod E into contact with the operating lever A. The rod E is formed with longitudinal teeth for engagement by a toothed rack 64 mounted for vertical displacement under the action of an eccentric pin 67 on a barrel lock 66 engaging in an opening 68. Operation of the barrel lock turns the plunger 75 so that the pins 78 abut the face of the plunger and the push button is then effective to cause unlatching.
