Title: Improvements in apparatus for manufacturing small articles such as pills or the like from plastic material
IPC: A61J3/06
Filed: 1930-01-31
Abstract: 343,292. Cutting and moulding pills &c. in cylinder and rolling machines. SUMNER, W., Dunelin, Broadgreen Road, Liverpool. Jan. 31, 1930, No. 3300. [Class 87 (ii).] Apparatus for manufacturing pills, pellets, or like small articles includes means for preparing a strip of plastic material of regulatable uniform thickness, a wheel with tubes forming pockets for cutting through the strip and removing portions therefrom and fluid pressure means for subsequently expelling the severed portions from the tubes. A strip of material of regulatable thickness is delivered from the hopper 1 by the toothed wheels 2 and the adjustable hinged knife 4 regulated by the screw 6. The strip is divided next into a series of bands by passing between the rollers 11, 12, being thus separated and retained in the recesses 15 of the flanged roller 12. A final gauging in regard to thickness is given by the roller 17 which is eccentrically mounted so that it can be set within fine limits. Tubes 21 projecting from the drum 13 cut out portions of the bands of material and carry them round until the inner ends of the tubes register singly or in rows with an air-pressure nozzle 28. The pressure expels the pellets which strike against a resilient surface 37 before falling into the delivery hopper 36. Pills would then be delivered to rolling-machines to form them into spherical shape. Reference is made also to a leather and metal air-seal between the nozzle 28 and the interior of the drum, to the removability and adjustability of the drum 13 through the medium of the levers 44, cam 45 and hand-wheel 48, and to the adjustability of the roller 11 through the medium of the levers 49 and set screws 50. The tubes 21 may be arranged helically on the drum so that only one at a time registers with the air-pressure apparatus.

IPC: G03B21/50
Filed: 1917-03-08
Abstract: 114,003. Dehn, F. B., (Bell & Howell Co.). March 8, 1917. Kinematograph apparatus.-Stop mechanism, in which a rod is moved into the path of an element carried by a rotating member, is provided with means for preventing recoil and for absorbing shocks. The pitman which operates the film-feed is attached to a crank-pin 12 on a shaft 8 which is rotated by a loose pulley 20 running between friction rings 19, 22, the ring 19 being secured to a cup-shaped 'extension 17 of a sleeve 14 which is keyed to the reduced portion 9 of the shaft 8, whilst the ring 22 is bolted to the sleeve 14 and is pressed against the pulley 20 by a spring 25. When the extension 17 and shaft 8 are stopped by projecting a rod 28 into the path of a pin 27, the pulley 20 continues to rotate. The rod 28 is normally held up against the action of a spring 30 by an arm 34 of a bell-crank lever, but is released when a disk 36 on the other arm is attracted by the core 37 of an electro-magnet 38 which is energized through a contact device engaging the edge of a picture film at predetermined points as described in Specification 113,513. The extension 17, Fig. 1, is fitted with a spring-controlled dog 39 provided with a projection 42 which, on contacting with the projecting bar 28, rides over it and then snaps in behind it so as to prevent recoil when the pin 27 strikes the bar 28. The shock-absorbing device comprises a member 43, Figs. 1 and 3, which loosely surrounds a sleeve 10 pinned to the shaft 8 and through a hole 59 in which the bar 28 is caused to project. When this bar is struck by the pin 27, it is slightly displaced laterally, to allow of which the opening in the end 32 is made slightly conical and the collar 31 is made a loose fit. This lateral movement is communicated to the member 43 and to one of the adjustable springs 55, 56, mounted on rods 49, 50 supported in bosses 51, 52 mounted on the framework.

Title: Improvements relating to the production of aryl ethers
Filed: 1954-02-09
Abstract: A process for the continuous production of anisole or phenetole from an alkali metal salt of benzene sulphonic acid and an alkaline earth metal hydroxide by heating a finely-powdered mixture of the reaction components in the fluidized state in the presence of methyl or ethyl alcohol at 300-400 DEG  C. and separating benzene ethers from the solid reaction products, comprises the features of maintaining in a <FORM:0756390/IV(a)/1> reaction chamber the fluidized reaction residue by passing the respective alcohol vapour through the said residue and continuously adding thereto starting materials and further reaction residue previously mixed and fluidized in a separate chamber by passing an inert gas therethrough; separating the respective benzene ether from the solid reaction products and residue by carrying the said vapour forward to a condenser with the alcohol vapour used for fluidizing the solids in the reaction chamber and recirculating the reaction residue with fresh starting materials; the amount of starting materials mixed with the reaction residue being adjusted to give a stream of material containing 10-50 per cent by weight of the starting mixture, and the level of the fluidized mass in the reaction chamber being maintained substantially constant by withdrawing from the circulating stream of powdered solids after discharge from the reaction chamber an amount corresponding to the fresh reaction residue formed in the reaction chamber.  In the apparatus shown in Fig. 1, the starting mixture in storage tank 3 is fed into mixing chamber 5 where it is mixed in the fluidized state, by means of an inert auxiliary gas such as nitrogen, with reaction residue from circulating conduit 1.  The fluidized mixture is fed through the screw conveyer 9 into the reaction chamber 10, the respective alcohol vapour being passed in at 12, and the vapours discharged at 13 to a condenser (not shown).  Reaction residue is removed at 14, sufficient i.e. about 10-20 per cent being removed at 15 to maintain a constant level of fluidized material. Various modifications are described including the stripping of the discharged solids by the alcohol vapour or steam which may be subsequently introduced into the upper part of the reaction chamber.  Potassium or sodium benzenesulphonate is used, admixed in the starting material with the hydroxides of calcium, barium, strontium or magnesium.  The amount of alcohol vapour used in the reaction chamber is sufficient to maintain the solids in the fluidized state and to liberate the respective aryl ether, a linear velocity of alcohol vapour of 10-30 cm. per sec. in the reaction chamber being sufficient.  The benzene ether is separated from the condensed vapours by distillation, a small amount of phenol being formed as a by-product.  In the example, anisole is prepared from methanol, potassium benzene sulphonate and calcium hydroxide in the apparatus shown in Figure 1.  Specification 591,896, is referred to.
