Abstract: 685,641. Delivering cards from statistical machines. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. Jan. 25, 1951 [Feb. 2, 1950], No. 2771/50. Class 100 (i). [Also in Group XIX] In apparatus to receive record cards delivered in succession from a statistical machine, movable means 7 impede the trailing edge of a card delivered into the top of the receiver 1 and retain the card in a tilted position for a predetermined interval, and a tilted card is displaced, transversely of its direction of movement, by means 6 actuated through a normally active coupling 37, 48 rendered inactive by a trip member 57 controlled by a function of the machine. The apparatus described comprises two receivers for cards passed through the machine described in Specification 685,642, [Group XIX], including comparing mechanism as described in Specification 685,640, [Group XIX]. On agreement of the compared cards, a bail shaft 68 is rocked, thus moving downwards a link 65, pivoted arm 62 and link 59 so that the trip pin 57 rocks a pawl 48, carried by a bar 36, out of engagement with a stud 37 on a bar 35 which is reciprocated during each machine cycle by a cam 46 on a driving shaft 17 and a bell-crank follower 42 engaging a stud 38; the pawl is held in inactive position by a latch 50 connected to it by a spring 52, and restored by the stud 37 on the return movement of bar 35. If the compared cards should disagree, however, the bar 36 is reciprocated with bar 35 and rocks a shaft 21 carrying the card pusher 6 through shafts 31, 24 and arms 26, 25. The card-impeding plate 7 is subsequently reciprocated between guides 8, 9 by an arm 10 on a shaft 11 rocked by a cam follower 19, thus allowing the card to fall onto the spring-supported platform 2. A similar pusher and plate for the other receiver (not shown) are simultaneously operated through linkworks 72, 73 and 76, 74 respectively. '

Title: Improvements relating to the manufacture of cigars, cigarillos or bunches therefor
IPC: A24C1/28
Filed: 1950-02-02
Abstract: 670,903. Cigar-making machines. NAAMLOOZE VENNOOTSCHAP VEREENIGDE TABAKSINDUSTRIEEN MIGNOT & DE BLOCK. Feb. 2, 1950 [March 3, 1949], No. 2773/50. Class 130. A device to ensure the picking up of a single binder or wrapper leaf at each operation of means such as a rotary suction leaf-holder 27, Fig. 5, transferring leaves to a rolling mechanism 28, comprises a magazine 1 holding a pile 2 of preformed binder and/or wrapper leaves in such a way that adjacent leaves may be laid upon each other crosswise. As shown in Fig. 2, the walls of the magazine confine a cross-shaped space in which successive leaves lie at right angles to one another. The leaves are presented to the holder 27, when the latter is in position above the magazine, by a piston 11 forming the operative bottom of the magazine and reciprocated periodically through a rod 12 by a spring 15 and rotating cam 16. A fixed guide, which may be constituted by two parallel rods or, as shown, by a plate 30 having cut therein an aperture 31, Fig. 6, allows only leaves aligned therewith to be picked up by the holder 27. To effect such alignment of the crossed leaves, the magazine is oscillated periodically by a linkage 5, 4, 7, Fig. 4, operated by a spring 8 and rotating cam 9. Filling of the magazine, which may be effected in a completely separate machine is carried out by oscillating the magazine in the manner of Fig. 4, at the same time transferring leaves thereto from a cutting matrix 21 by means of a suction leafholder 20 oscillated at twice the rate of the magazine by a spring 24 and rotating cam 25. More than two crossed piles of leaves may be employed, the mechanism for turning the magazine being suitably modified. The magazine may be formed to hold the crossed leaves at any angle relative to each other and in the form of a Vee or other open geometrical figure, or in the shape of a triangle or other closed geometrical figure. Fig. 3 shows a magazine 1a for holding four piles of leaves. Where the leaves are of suitable shape, the magazine may be intermittently rotated instead of oscillated. A magazine may be constructed to hold crossed binder and wrapper leaves. Such a magazine may be filled from two appropriately shaped cutting matrices, either by employing a single leaf holder, into coaction with which the matrices are alternatively brought as on a turntable, or by employing two alternatively operable leaf holders co-acting, with individual matrices, when the magazine may be stationary. The invention is applicable to the manufacture of cigars, cigarillos or bunches therefor.

Filed: 1931-01-28
Abstract: 371,931. Printing-machines. HOE & CO., Ltd., R., 109, Borough Road, London. -(Hoe & Co., Inc., R. ; 138th Street, New York, U.S.A.) Jan. 28, 1931, No. 2810. [Class 100 (ii).] Gripper mechanism. -A gripper mechanism for a printing- machine, adapted to take a sheet from registering stops 21 and hold it on a uniformly and constantly rotating cylinder 11, comprises the combination with the rotatable impression cylinder 11, a gripper-carrier rotatable relatively to the cylinder 11, and a gripper device on the carrier, of means for rotating the carrier oppositely to the rotation of the cylinder during a portion of its revolution. The carrier comprises arms 22, 22<1>, mounted on the cylinder shaft 12 and carrying a cross-member 24, provided with registering stops 49 and forming a seat for gripper fingers 25 secured to a shaft 26, rotatable in the arms 22, 221. An arm 27 secured to the shaft 26 carries a roller 29 at one end and is pivotally connected at the other end to a plunger-rod 32, which carries a spring 34 tending to turn the shaft 26 to close the grippers. The arms 22, 22<1> are extended beyond the shaft 12 and carry links 38, 381 to which are pivoted arms 41, 41<1> secured to a shaft 42, rotatably supported in the cylinder 11 and extending beyond the cylinder to form an arm 43 which carries a roller 45 engaging a cam-surface 46 secured to the frame. In operation, as shown in Fig. 3, the cam 46 acts on the roller 45 to move the arms 22, 22<1> backwards to take the sheet, the fingers meanwhile being opened by a cam 35 on the end wall of the cylinder engaging the roller 29 on the arm 27. On continued rotation the cam 46 causes the gripper-carrier to move farther backwards with respect to the cylinder, then arrests its motion, at which point the fingers 25 close on the sheet, and finally accelerates the carrier to the speed of the cylinder, with which it rotates, the member 24 being then in contact with the part 15. The fingers are opened to deliver the sheet to a transfer cylinder 18 by a cam 36 on the frame which engages the outer end of the roller 29, after which the carrier is accelerated relatively to the cylinder to travel across the gap therein and arrive adjacent the end 16 preparatory to gripping the next sheet.

Abstract: 1464276 Making can closures; seaming NATIONAL CAN CORP 21 Jan 1974 [22 Jan 1973] 02826/74 Headings B3A and B3J [Also in Division B8] An easy-open metal container end is formed by swaging a panel 12 having a base portion 37 and a flanged upstanding peripheral wall portion 39 between dies 50 and 54 to form a thinned rupturable weakened area 18 at the base portion/ wall portion junction to define a removable panel section 14, and thereafter radially expanding the panel to remove at least some of the compressive forces developed in the removable panel section by the flow of excess metal into the removable panel section during the formation of the weakened area. The die 50 has a convex surface 62 between a bottom recess 64 and a surrounding rim 66 which co-operates with a convex surface 58 on the die 54 between a bottom radius 56 and a bottom surface 60 to form a weakened area bounded by opposed arcuate concave surfaces 40 and 42 so that the area is of continuously reducing thickness towards its centre. The panel 14 is displaced downwardly into the recess during swaging. The panel is then radially expanded between dies 80 and 84, the die 84 being of greater diameter than the die 54 and having a bottom radius 90 greater than that of the die 54 so that the compressive stresses induced into the removable section 14 by metal flow during the formation of the weakened area are removed. The expansion reduces the inclination of the wall portion 39 relative to a normal to the base portion 37, increases the size of the base portion so that the weakened area is located therein, and draws the downwardly-displaced section 14 upwardly. The dies 50 and 80 may be combined into one unit. In another modification, the dies may be configured so that the panel section 14 is displaced upwardly during the swaging operation. An interrupted circumferential bead 20, a trough 26, a transverse bead 34 and a dished portion 36 as described in Specification 1,383,067 may be provided in the panel. In order to allow pivoting of a pull tab 30 during opening, an arcuately-extending weakening area 120, Figs. 10 to 12 (not shown), is swaged into the panel about a hollow pull tab-fastening rivet 28 during movement of the swaging dies 50 and 54 by a convex surface on the female die and a co-operating convex bottom radius 12 of an annular male die element 110. This area subtends an angle of 75 degrees, has a chordal length equal to the rivet diameter, and may be adapted in use to rupture on raising of the tab to vent the container prior to initiating rupture of the weakened area 18 by the tab.

Title: Improvements in and relating to the catalytic treatment with hydrogen of glyceride oils or fats
IPC: C11C3/12
Filed: 1944-02-17
Abstract: 578,102. Hydrogenated fats; purifying fats; catalytic materials and processes. LEVER BROS. & UNILEVER, Ltd. Feb. 17, 1944, No. 2944. Convention date, Feb. 19, 1943. [Classes 1 (i) and 91] Oils and fats are decolorized and, if desired, hardened as well, by treating them at an elevated temperature with hydrogen in the presence of a small proportion of a catalyst whose ingredients contain the elements iron, oxygen and one or more of copper, silver and gold. The metals must have been co-precipitated in the form of hydroxides or oxygen-containing salts such as carbonates from a common solution of their salts although the precipitate may be ignited before being used as a catalyst. Hardening is facilitated if the ingredients of the catalyst contain, in addition, one or more of nickel, palladium, platinum or other metals which promote the hydrogenation of fats and oils. The hydrogenation, which is preferably conducted at superatmospheric pressure, may precede or follow hydrogenation in the presence of the conventional catalysts and it may be preceded by an alkali-refining process and followed by a stream deodorization. Suitable catalysts are prepared by adding sodium bicarbonate to a solution containing the sulphates of (A) copper and iron or (B) copper, iron and nickel and in each case drying and grinding the carbonate precipitate. In examples of the hydrogenation of oils and fats, continuous and batch processes are described for the hydrogenation of cottonseed oil or palm oil in the presence of catalysts A or B, whether ignited or not, or alternatively in the presence of catalysts prepared (i) as in A except that silver nitrate is used instead of copper sulphate or (ii) as in B except that cobalt sulphate is used instead of nickel sulphate. The properties of hydrogenated cottonseed oil prepared by hydrogenation according to the invention in presence of ignited catalyst A or B are also compared with those of hydrogenated cottonseed oil obtained with the aid of other ignited carbonate catalysts containing (a) nickel, (b) iron, (c) copper, (d) nickel, iron and copper, the various carbonates being ignited separately and then mixed, (e) iron and copper, the carbonates being mixed immediately before ignition (f) nickel, iron and copper, the carbonates being mixed immediately before ignition. The properties of a hydrogenated mixture of soya bean oil, cottonseed oil and coconut oil prepared by hydrogenation according to the invention in presence of ignited catalyst B are also compared with those of a hydrogenated mixture of the same oils prepared after preliminary bleaching with absorptive clay and carbon, by hydrogenation with a conventional nickel catalyst. Specification 440,934 and U.S.A. Specification 2,123,342 are referred to.
