Title: Automatic lathe with movable headstock
IPC: B23B7/02
Filed: 1945-09-18
Abstract: 608,610. Lathes. BECHLER, A. Sept. 18, 1945, No 24111. Convention date July 21, [Class 83 (iii)] An automatic lathe provided with an axially traversed headstock is characterized in that the headstock is actuated alternately during each cycle of the machine by a bell-shaped cam and one or more disc-shaped cams. The headstock 11 carrying the hollow spindle 12 and barstock 15 is traversed along ways 10 alternately by flat or disc cams 36, 37, on a transverse cam shaft 35, and a cylindrical or bell-shaped cam 22 mounted on a cam-shaft 19. A rest 16 supports the work close to the tools which may be held stationary for plain turning or may be traversed during longitudinal feed of the work to cut tapers. During the working cycle, the flat cams operate first to lift levers 41, 48, one of which carries a pivoted shoe 45 adjustable in a slot 43, the shoe bearing against a stop block 55 adjustable along ways in the side of the headstock. The outside disc cam 36 operates a lever 41 which bears against an adjustable stop 49 on the bell-crank lever 48 operated by the inner cam 37, the movement of the outer cam is thus adjustably superimposed on the bell-crank lever. As the headstock moves to the left under the action of the disc cams, a lever 24, Fig. 2, connected to the headstock by an adjustable link 27, 28 is moved clockwise and a follower 26 on the other end of the lever passes through a gap in the cylindrical cam 22 to be subsequently operated by this cam for the remainder of the working cycle, including the further feed to the left of the headstock. The operative portions of the cylindrical cam may be secured in a groove in the supporting drum for adjustment. The cam-shafts are geared together by bevel-wheels 32, 33 and are driven from a pulley 21 through worm gearing 20.

Abstract: 1,105,577. Acoustic enclosures. H. G. FAUCHERRE. 8 June, 1965 [17 June, 19641, No. 24115/65. Headings H4J and H4X. A loud-speaker enclosure includes a diaphragm which produces a focused or focusable beam of sound waves which are channelled through smooth non-absorbent ducts to an outlet situated at the focal plane of the diaphragm or the means used to focus the beam. The outlet is of smaller area than the diaphragm. The sound waves normal to the cone of a moving-coil loud-speaker 9 are guided through ducts 15 to cylindrical reflectors 13 whereby the waves are focused at apertures 14. Segments 10, 11 (Fig. 6) of the cone are blanked out so that a line output at apertures 14 is obtained. If a spherical reflector (Figs. 7 and 9, not shown) and the full output from the cone are used a circular aperture is provided. The diaphragm may be plane (Figs. 11, 13, not shown), concave (Figs. 15, 17, 20, not shown) or bi-concave (Fig. 19, not shown) and a relevant focusing system is utilized. A loud-speaker enclosure providing an omni-directional output in a horizontal plane is depicted in Fig. 13 (not shown) and a pair of back-to-back diaphragms with a transducer assembly located between them is depicted in Fig. 20 (not shown). Movable reflectors may be located adjacent each outlet for directing the beam in any particular direction. Resonant enclosures may alternatively be located adjacent the outlets. More than one loud-speaker may be mounted in a cabinet but each loud-speaker is provided with its own enclosure. The reflectors may be of hard wood, metal, glass, varnished cement or moulded resins and the ducts may be of wood or moulded material.

Title: Improvements relating to printing machines
IPC: B41F31/30
Filed: 1945-09-18
Abstract: 593,181. Printing - machines. THOMLINSON, Ltd., J., and THOMLINSON, W. G. Sept. 18, 1945, No. 24161. [Class 100 (ii)] In an inking-mechism for a printing- machine an ink distributing roller is adapted to be tilted so that one end only remains in contact with a main inking roller and to be moved in steps across the main roller and then reversed and moved similarly in the opposite direction. The hollow distributing roller 1 rotates on end bosses 3 having oblong slots 4 through which passes a polygonal bar 5 fixed to the frame 6. A rod 14 to which is pivoted a two-armed pawl 15 is pivoted at each end to an arm 13 on a spindle 9 in a bracket 10 fixed to the boss 3 which spindle also carries a crank arm 11 having a roller 12. When the roller 1 reaches one end of its travel over the main roller 8, say the left-hand end in Fig. 4, a bar 17 carried by the rod 14 is engaged by a stop 19 and moved to the right, causing the pawl 15 to rotate slightly in an anti-clockwise direction bringing its lefthand arm into engagement with one of the teeth of a rack 16 which is reciprocated from a suitable part of the machine. As the rack 16 moves to the right, the pawl 15 and the rod 14 are carried with it and the roller 12 at the lefthand end is raised from the bar 5, while the roller 12 at the right-hand end is forced down on to the bar 5 causing the right-hand end of the roller 1 to be raised, Fig. 9b. Continued movement of the rack 16 to the right moves the tilted roller to the right, and when the rack moves back to the left, the release of the pressure on the bar 14 allows the roller 1 to fall on to the roller 8. When the rack again moves to the right, its next tooth engages the pawl 15 and the roller 1 is again tilted and moved to the right. A second stop adjacent the right-hand end of the roller 8 engages the bar 17 to reverse the movement of the roller 1. Preferably two distributing rollers working on two main rollers and starting from opposite ends are operated from the same rack.

Abstract: 1,185,183. Purification of acrylonitrile. UGINE KUHLMANN. 25 May, 1967 [27 May, 1966], No. 24337/67. Heading C2C. Acrylonitrile, produced by the vapour phase catalytic reaction of propylene oxygen and ammonia at an elevated temperature, is purified by the removal of oxazole therefrom by contacting the acrylonitrile with a cation exchange resin in its acid form which is insoluble in the nitrile. The impure nitrile may be passed through a bed of the cation exchange resin, which may be based on polystyrene cross-linked with divinyl-benzene and sulphonated, at a flow rate of 4-60 volumes per volume of resin per hour. The heterocyclic compound may subsequently be eluted from the resin by washing with deionized water optionally at an elevated temperature, or by washing with water combined with treatment of the resin with steam followed by condensation of the resulting vapours.

Abstract: 351,806. Folding paper. WINKLER, A. and DUNNEBIER, M., Neuwied, Germany. Aug. 18, 1930, No. 24651. Convention date, Aug. 19, 1929. [Classes 100 (i) and 100 (ii).] Pile tables for sheet-feeds; sheet-separators.-In apparatus for separating a sheet from the bottom of a pile and simultaneously forming a fold therein, the pile 3, Fig. 1, is supported on an inclined plate 2, 21 having a gap therein wherein are situated suction separating and folding devices. The suction devices may consist of a suction roller or rollers, but, as shown, consist of a suction segment 5 on a rotating tubular member which is reduced in diameter over the non-suction part of its periphery. A plain roller 6 co-operates with the segment 5 to separate the sheet and form the fold. Axially arranged rows of holes 7 in the segment 5 communicate with the interior of the tubular member through which suction is applied from a suction pipe 18, Fig. 5. The gap in the plate 2, 2<1> is curved to receive the members 5, 6 and so that the rows of holes 7 come into operation successively as they leave the curved part of the plate 2. The folded sheet is received by a pair of high-speed 12, 13 rollers. To control the suction, the opening between the pipe 18 and the tubular member can be varied as regards extent and timing by means of a sleeve 16 situated between the pipe and member and adjustably connected to the pipe 18 by a setscrew. Slits 21, 22 are provided in the member and sleeve respectively, and by adjusting the sleeve and varying the overlays of the slits, the suction can be suitably controlled. If narrow paper sheets are being operated on, the holes 7 at the ends of the segment 5 are closed by an adjustable core member or an external covering slide. The positions of the segment 5 and the roller 6 may be the reverse of those shown, and the rollers may be replaced by a suction segment.
