Title: Improvements in and relating to copy holders
IPC: B41J29/15
Filed: 1949-01-17
Abstract: 673,949. Copy-holders. RICKARDS, G. S. April 6, 1950 [Jan. 17, 1949; Aug. 5, 1949], Nos. 1251/49 and 20394/49. Class 100 (iii). In a copy-holder, the copy is held between roller means which, in order to advance the copy progressively past an index, are rotated by depression of a handle forming part of a remote control unit movable relative to the copy-holder and coupled thereto by a flexible cable by means of which depression of the handle is caused to effect rotation of the roller means. The copysupporting surface comprises a sheet metal plate 10, Figs. 1 and 3, to which is riveted a shaft 17, Figs. 1 and 5, supporting brackets 18 on which are mounted a line indicator framework 15 and a shaft 20, each biassed towards the plate 10 by springs 19. Cork or rubber faced rollers 21 on the shaft 20 co-operate with similar rollers 22 on a short shaft 23 secured to the plate 10, to hold or feed a sheet .40, the rollers 22 projecting through apertures in the plate 10. Additional support for the sheet is given by arms 43 pivoted to a back plate 11 and members 44 slidable on the framework 15. A further strip member may be bolted to the plate 10 at the level of the framework 15, having arms extending sideways to support wider copy sheets. The shaft 20 is manually settable by knobs 27 and carries a ratchet wheel 24. A drum 26 enclosing the ratchet wheel 24 is freely mounted on the shaft 20 and has three angularly spaced pawls mounted within it to engage the ratchet wheel. The drum 26 is secured to a pulley 28 biassed by a spring clockwise in Fig., 3. On depression of a handle 38 of a remote-control unit 35, a Bowden cable 31 secured to the pulley 28 causes the shaft 20 to be rotated by the pawls to feed the copy sheet one step upwards, the amount of feed being controlled by an adjustable stop 41 for the handle 38. An elongated magnifying lens may be secured to the framework 15 to facilitate reading of the portion of the copy sheet immediately above the framework. Rubber suction pads are provided as feet to prevent slipping of the copy-holder. A handle 9 facilitates pivoting outwards of the framework 15 for insertion of a sheet. A spring 45 is coiled round the back plate 11 to support a notebook.

Title: Improvements in and relating to Repeating and Stopping Devices for Phonographs, Talking Machines and the like.
Inventor: MITCHELL FRANK BOWLEY
IPC: G11B3/08
Filed: 1916-01-31
Abstract: 103,523. Mitchell, F. B. Jan. 31, 1916. Brakes, arrangement of; returning soundbox to starting-point; positioning needles in sockets, tools for; disk records. - A friction block carried on the sound-box is arranged to drop on to the record surface at the end of reproduction and acts either as a brake to stop the record or as a repeating-device to return the sound-box to the starting point. In the construction shown in Fig. 3, the block C is of eccentric form pivoted at C<2> to an adjustable plate C<2>. At the end of a reproduction, the needle falls into a deep groove E<2>. and the block C makes contact with the record and, by rotation on its pivot C<2>, lifts the needle clear. According to the adjustment of the plate C<4> in the slot C<3>, the block C either stops the record or is dragged by the moving record to the outer edge, the needle again falling into the playing-groove at the starting point when the block C passes over the edge. The block C is weighted or spring-controlled so that, when free, it returns to normal position. The deep groove E<2> may be replaced by a depressed central portion of the record. For outwardlyplaying records, the block C is placed on the inner side of the stylus, and the deep groove E<2> is formed near the rim of the record, or the playing-groove is continued to the record-rim. Instead of a pivoted eccentric block, a fixed block may be used, or a block sliding in an inclined groove in a member secured to the sound-'box on the tone-arm, or a block H, Fig. 6, suspended by links K, K<1> and balanced by a counterweight K<2>. The swing of the tone-arm may be assisted by slightly inclining its pivot, and a removable stop may be placed in its path, which, when in position, limits the return motion of the tone-arm and allows the friction block to arrest the record. In order to ensure that the needle always projects the same distance from its socket, the point of the needle is first inserted in a blind-hole L<3> in a member L, Fig. 7, having an adjustable base L<1>. The needle is clamped in the stylus socket while still resting in the member L, which is then removed.

Patent GB-826098-A (GB)
Title: Wet spinning cellulose triacetate
IPC: D01D5/06
Filed: 1958-01-20
Abstract: A solution of cellulose triacetate in methylene chloride, or in a solvent consisting chiefly of methylene chloride, is spun into a coagulating liquid containing more than 25% of methylene chloride by weight and a 1 to 3 carbon atom aliphatic alcohol, preferably methanol, and the filaments thus formed are stretched during their passage through the coagulating liquid.  The conditions employed are predetermined to yield yarn having a tenacity of at least 1.8 grams per denier coupled with an extensibility of more than 18%, as determined by described methods.  Both maximum tenacity and maximum extensibility are generally obtained when the coagulating liquid contains about 50% by weight of methylene chloride.  The cellulose triacetate should have an acetyl value of at least 60%, and preferably above 61%, calculated as acetic acid.  Its intrinsic viscosity (as determined by a described method) should be about 1.5 to 3, and especially 2 to 3.  The spinning solvent may contain a small proportion of a 1 to 3 carbon atom aliphatic alcohol, e.g. up to 15% by weight of methanol on an anhydrous basis.  The concentration of cellulose triacetate in the spinning solution may be about 18 to 26%, especially 20 to 23%, by weight, and the viscosity of the solution at the spinning temperature may be about 500 to 6000 poises.  The temperature at which the solution is spun is preferably between about 15 DEG  and 45 DEG  C.  The coagulating liquid is preferably also at a temperature between 15 DEG  and 45 DEG  C., and especially between 15 DEG  and 40 DEG  C.  In general the concentration of methylene chloride on an anhydrous basis to be used in the coagulating liquid is within the range defined by the formula 75.25 - (T \sB 5)%, where T is the temperature of the liquid in degrees centigrade.  The coagulating liquid preferably does not contain more than 4% by weight of water.  The draw-down ratio of the filaments in the coagulating liquid may be between 15 and 3.5 to 1, preferably between 10 and 5 to 1.  The take-up speed may be above 100 metres per minute.  In an example, a 24% solution of cellulose triacetate in a 90.5 : 9.5 wt/wt. methylene chloride-methanol mixture is spun into a coagulating bath comprising a methylene chloride-methanol 48 : 52 wt/wt. mixture at a temperature of 27 DEG C., and the filaments are drawn from the bath at a drawdown ratio of 5.8 : 1 and wound up on a roll at the rate of 90 metres per minute.

Abstract: 706,774. Gas turbine plant. GENERAL MOTORS CORPORATION. Jan. 25, 1951 [Feb. 4, 1950], No. 1895/51. Class 110 (3) The rear bearing of a turbine is cooled by a flow of air induced directly from the atmosphere through radially disposed pipes solely by the flow of gas through the turbine exhaust system. The rear bearing 14 is cooled by air which passes through conduits 40 the ends of which are secured in apertures in the casing extension 41 and the wall 44 of the cooling air chamber 42. From the chamber 42 the air passes through apertures 48 and an annular passage around the bearing to the space between a partition 50 and the turbine wheel 34. The air is drawn out of this space by the action of the gases flowing through the exhaust passage. Air is also drawn from the chamber 42 and led into the exhaust pipe through the aperture 54, the fairing 30, the passage between the struts 38 and conduits 40 and the aperture 43. This air insulates the cooling air supply to the bearing from the hot exhaust gases,

Title: Improvements in or relating to olefinic polymers for use in the production of alkyl aromatic sulfonate detergents
IPC: C07C2/18
Filed: 1951-01-26
Abstract: A C11-13 polymer fraction is prepared by polymerizing an olefine mixture of propene and butene containing essentially propene and n-butene in a proportion of 3 to 10 mols. of propene per mol. of n-butene and less than 1/2 mol. of isobutene per mol. of n-butene in the presence of a phosphoric acid polymerization catalyst under polymerization conditions including temperatures from 350 DEG  to 500 DEG  F., and separating from the total polymer product a C11-13 polymer fraction boiling in the range of 360 DEG  to 425 DEG  F.  The term n-butene is used to denote butene-1 and/or -2.  Optimum yields are obtained by continuously feeding the feed, preheated to 250-450 DEG  F., through a catalyst chamber maintained at e.g. 425 DEG  to 475 DEG  F. and a pressure of between 100 and 2000 p.s.i.g., passing the products to a recovery zone where unreacted hydrocarbons are separated from the polymers and fractionating the polymers to recover C6, C7, C8-11, C11-13 and C13+ fractions of which the C6 and C8-11 fractions are recycled to the catalyst chamber.  Suitable apparatus is described.  The phosphoric acid catalyst is preferably used on an adsorbent carrier, e.g. kieselguhr, alumina, diatomaceous earth or silica, on which it is precalcined at about 400-500 DEG  F.; a small amount of water or steam is added to the alkene feed to maintain activity of the catalyst.  Data is given showing the effect on the yield of omitting C7 polymers from the recycle polymers and yields are composed using a propene-n-butene feed, a propene-propane feed and a propene-n-butene-isobutene feed containing less propene and more isobutene than the specified feed of the invention.  The C11-13 polymers may be used in the preparation of alkylated aromatic sulphonate detergents as described in the Provisional Specification 751,839.
