Title: Improvements in or relating to devices for turning the pages of books, such as musical scores
IPC: B42D9/06
Filed: 1955-06-15
Abstract: 776,217. Leaf turners. DURAND, J. VULLIET-. June 15, 1955 [Oct. 8, 1954], No. 17235/55. Class 52 (3). A leaf turner for musical scores etc. comprises a flat plate 1 on which is mounted, at a slight angle to the book centre line, a resilient circular bellows 7 carrying a tubular arm 15 to which is attached a bellows 17 having a suction member 18. The arm 15 communicates with the interior of bellows 7 through an endpiece 14 of sponge rubber or plastic, and with bellows 17 by an extension arm 16. The other end of bellows 7 has a similar endpiece 8 connecting the bellows by way of members 12, 13 to a large bellows 22. In the normal position, the suction member 18 is resiliently held against the upper right hand edge of a page by bellows 7. On depressing bellows 22, air is exhausted from bellows 7 and suction member 18 through a non-return valve (not shown) and subsequent release of bellows 22 results in the creation of partial vacuum which causes bellows 7 to contract, swinging arm 15, together with the page to which the suction member 18 now adheres through 180 degrees to position 15a. Seepage causes return of air into bellows 7 and suction member 18 whereupon the resiliency of the bellows raises arm 15 to position 15b and returns it to the upper right hand side of a new page.

Title: Fugitive colouration of polyamide fibres, threads, yarns and the like
Inventor: WILD ARTHUR SCOTT
IPC: D06P5/13
Filed: 1953-06-29
Abstract: Temporary colouration of polyamide fibres, threads or yarns during their processing as textile materials is achieved by applying to the fibres an aqueous dispersion of a quaternary salt of an acid dyestuff, the dispersion also containing a nonionic dispersing agent, and then removing the dyestuff by a scouring operation at a subsequent stage in the processing, preferably a stage subsequent to a steaming operation.  The dispersion may be added to the warp size or knitting gum which is applied to the polyamide fibres.  A specified dispersing agent is the condensation product of an alkyl-phenol with ethylene oxide.  A specified quaternary salt is that obtained by adding lauryl-pyridinium bromide to an aqueous solution of the acid dyestuff, many of which dyestuffs are listed.

Filed: 1940-12-20
Abstract: 541,263. Grinding screw-threads. ATKINS, H. F. Dec. 20, 1940, No. 17936. [Class 60] In machines for grinding internal screwthreads by means of a wheel 6 which is separated from the work 2 after each cutting traverse and is then returned to starting position, the separating movement is positively determined by a fixed or adjustable stop 8 in the path of the wheel-slide 4. The arrangement enables the separating movement to be performed quickly and definitely and, by reducing such movement to a minimum, permits the use of a wheel of approximately the same size as the hole 3 in the work. The slide can be traversed by means of a piston 12 and cylinder 13. Alternatively, spring or screw means may be employed. A screw 10 is formed with a shoulder 9 for limiting the cut-movement of the slide. The screw may be provided with an adjustable stop 11 for limiting the separating movement of the slide when a hole of considerably larger diameter than the wheel is being ground.

Title: Improvements in or relating to electric vibrating contacts
IPC: H01H35/14
Filed: 1918-11-04
Abstract: 206,102. Roberts, A. J. Nov. 4, 1918. Switches, quick-make.-Relates to devices in which the vibration of a diaphragm K closes a circuit at B<2>, C and consists in means whereby the necessity for placing these contacts very close together is obviated. The contact B<2> is carried by a lever BB' pivoted on a knife-edge at A and is normally retained in a position determined by a stop L by a permanent magnet F acting against the pull of a spring E. The magnet F and spring E just balance each other in this position, but a very small movement of the lever BB<1> will diminish the power of the magnet and allow the spring E to bring the contacts B<2>, C together. This movement is produced when the diaphragm K vibrates by a member D mounted on a pivot D<2> and acted on by a spring M. The arm BB<1> may be re-set by completing the circuit to an electromagnet G.
