A machine for folding down flaps of a flat box &c. blank onto other elements of the blank comprises means, moving relative to a line along which the blank is advanced, for upfolding a flap and stationary means for folding the flap down onto the other blank elements. In folding flaps leading the blank in its line of advance, pivoted rotating fingers 112 engage under a pair of flaps 30, 32, the blank being held down by conveyer chains 101, 102. The fingers 112 rotate in the direction of blank travel, but move slowly and turn up the flaps for engagement by the stationary folders 130 which complete the operation. Elements 150, rotating with the fingers 112, may engage the blank behind the flap hinge line 38 to prevent it rising. Tabs 34, 36 are given an initial downward displacement by elements 171 carried round on chains 170, and are partially folded by stationary folders 177, the blank then passing from beneath chains 101, 102 to chains 201, 202. Fingers 212, similar to fingers 112, turn up flaps 31 and 33, the folding being completed by stationary folders 230. Further stationary folders 260 engage the tabs 34, 36 to fold them onto the flaps 31, 33. The folded blank passes through conventional mechanism A for printing areas of adhesive B on the tabs. If trailing flaps such as 25 26,, 27 are to be infolded, fingers 517, Fig. 14, are arranged to be advanced by chains 510 in the direction of, and at a greater speed than the blank. The fingers are rotated by a fixed cam 550 acting on rollers 521 attached to the finger levers 514. Elements 650 functioning in a similar manner to the elements 150 may also be provided. Fixed folders 633 complete the folding down of the flaps. Specification 731,678 is referred to.

Abstract: 470,217. Lapping - machines. NORTON CO. Sept. 4, 1936, No. 24206. Convention date, Sept. 11, 1935. [Class 60] A lapping-machine, for treating the flat ends of cylindrical &c. work-pieces, comprises a base 10 supporting a rotatable lower lap 11 and having a column 12 with a horizontal part 13 to support the spindle 14 of an upper lap 15 connected to the spindle by a plate 16. The laps are driven from a shaft 23, which is driven by a belt 20 through a clutch 22 operated by a lever 28 and rod 32, a brake 40, 41 also being provided to stop the shaft 23 when the clutch is opened. The lower lap 11 is driven by worm &c. gearing 70, 71, 75, 76, and the work is mounted in apertures in a cage 66, which is given an irregular combined rotary and planetary motion. The upper lap is driven by worm gearing 45, 46 through a universally jointed shaft 49 and belt gearing 55 ... 57, the belt being tensioned by adjustment of a bracket 54 by a screw 62. The spindle 14 runs in bearings 80, 81 in a sleeve 82 slidable in a casing 83 formed on the arm 13, and secured to the sleeve 82 is a rack 85 engaged by a pinion 86 connected by chain gearing with a sprocket 96 carried by an adjusting bracket 92 pivoted at 93, a counterbalance weight 98 being carried by the sprocket through a chain 97. Downward movement of the lap 15 is limited by an adjustable stop 100 mounted in a bracket 101 secured to the casing 83, the stop being engaged by an adjustable stop screw 106 mounted in a bracket 107, which may be secured in different positions, to suit work of different thicknesses, on the sleeve 82 by screws engaging threaded holes 108 in the sleeve. The pressure between the laps and the work is provided and regulated by fluid pressure means comprising two cylinders 120, 121 mounted on opposite sides of the casing 83 and provided with pistons 126, 127 respectively, connected by rods 128, 129 with a plate 130 connected to the lower end of the sleeve 82 ; by this arrangement the lap 15 moves parallel to itself. Fluid is supplied to the cylinders from a reservoir 140 by a pump 143 and passes through a reversing valve 144 operated by a lever 166, and in order that the pressure of the laps on the work may be either of two desired values, for example, a heavy pressure for rough lapping, or a light pressure for finishing, a relief valve 170 is mounted in the supply line 143 and is adjustable by a screw 172 and spring 174 to open under pressure greater than that required for the rough lapping. A second relief valve 180 similar to the valve 170 also is connected through a manually-operated valve 190 to the line 143 and is set to operate at the lower desired pressure; during rough lapping the valve 190 is closed. The valves are adjusted with the aid of a pressure gauge 195 and by operation of the valve 190 any desired sequence of pressures can be obtained. Specification 254,919, [Class 60], is referred to.

Title: Improvements in or relating to the Gravity Separation of Granular Materials
Inventor: MULLER LESLIE DYNE
IPC: B03B4/06
Filed: 1965-06-08
Abstract: 1,153,722. Separation of granular materials. NATIONAL RESEARCH DEVELOPMENT CORP. 3 June, 1966 [8 June, 1965], No. 24224/65. Heading B2H. In a separator for granular materials, e.g. ores, the materials to be separated pass down an inclined surface under the influence of gravity to form separate layers of material at the discharge end of the inclined surface, the area of the surface decreasing from the top downwards so that the depth of materials on the surface is increased as the materials pass down the inclined surface, and means are provided to effect fluidisation of the downpassing materials by fluid introduced beneath the materials. In Fig. 3, dry material is fed from a hopper 23 by a vibratory conveyor 24 to the top of a so-called "pinched sluice" 25 which takes the form of an inclined chute with tapering side walls Fig. 2 (not shown). The floor 26 of the sluice is porous and forms the upper part of a box 27 to which air under pressure is continuously fed at 28. The air passes through the floor and fluidises the material which passes down the floor thereby assisting its stratification into components of different density or size which are separated from one another by means of a slot 29, a sputter 30 being also used if desired. To further improve separation, the air may be pulsed by means of a diaphragm 31 connected to the box 27. Alternatively, the material may be supplied mixed with water to form a pulp, fluidisation being effected by passing liquid and/or gas through the porous floor 26. In another embodiment, Figs. 4 and 5, the incline is constituted by an inverted conical vessel 33 to the rim of which the material is fed in an annular stream by means of a distributor which may consist of a feed cone 34 to the apex of which the material is supplied, the cone carrying a cylindrical skirt 35 terminating in a frusto-conical flange 36 and the cone and skirt being surrounded by a cylinder 37 for further guiding the material. The greater part of the surface of the conical vessel 33 is made of porous material 42 through which fluid is forced via a box 43, the fluid being pulsed if desired. The distributor cone 34 may also be provided with a porous surface to effect fluidisation of the feed material thereby improving the regularity of the feed. As a result of stratification on the porous surface of the conical vessel 33, coaxial streams of material of different density or size emerge from the apical discharge orifice (38) of the vessel to be carried away through adjustable coaxial pipes 39, 40. Alternatively, the streams may be separated by means of slots 41 in the surface of the wall of the vessel.

[Also in Groups XXVI] Water or other liquid is heated or cooled in a closed casing 10 (according to whether an electric heater 12 or a refrigerating coil 13 is operated) and is passed by a pipe 17 to at least one heat exchanger 18 by means of a hand-rotated cylindrical body 27 to which the liquid returns through a pipe 19. The heat exchanger 18 may be of copper, aluminium alloy or stainless steel for use in rooms, roofs (e.g. of cars), refrigerators, cold stores, marine craft or aircraft (e.g. for melting ice on the exterior), or it may be of synthetic resin for use in windows, or of rubber or nylon for incorporation in a blanket, mat, cushion or an article of clothing. There may be fluid-filled closed passages 100, for withstanding external pressure, arranged around the edge of the heat exchanger 18 and extending between the loops of its continuous zig-zag liquid duct. The pump 27 is divided into two compartments 44, 45 and the upper compartment empties by gravity through the system into the lower compartment until the body is rotated about its axis through 180 degrees by means of a folding handle, Fig. 4 (not shown), to reverse the position of the compartments to restart the flow. The fixed inlet and outlet connections with which openings of the compartments 44, 45 register when the pump is operated are in the bearing of an axial spindle of the body 27 and there are internal tubes, Figs. 2, 3 (not shown), interconnecting the compartments for venting of air from the lower compartment to the upper, one tube being closed at a time, by a ball valve, to prevent direct flow of attemperating liquid from the upper compartment to the lower. The liquid flow is controlled by a valve 25 and there are valves 20 by which the flow of refrigerant from a refrigerator 14 to the coil 13 may be shut off. The spindle of the handpump 27 may be supported in the headboard of a bed or settee, Fig. 5 (not shown), or in the back of a chair. The Provisional Specification describes also a system in which oil or gas is circulated and in which the circulating fluid is cooled by solid carbon dioxide packed in the casing. The heat exchanger may be formed with transverse ducts interconnecting flow and return pipes which extend along its longitudinal edges or be formed with a zig-zag duct with an outlet part extending along one side and it may be incorporated in a diving-suit.

Title: Organic sulphur-containing derivatives of antimony which can be used as stabilisers for chlorine-containing polymers
Inventor: MALZ HUGO
IPC: C07F9/72
Filed: 1963-06-19
Abstract: Polymers of vinyl chloride or vinylidene chloride, 2-chlorobutadiene or copolymers of these compounds with vinyl acetate or chlorine rubber or sulphochlorinated polyethylene are stabilized by adding organic antimony compounds which are prepared by reacting an antimony trihalide or trioxide with thioglycollic acid and/or at least one 1-mercapto-2-hydroxyalkanes in an aqueous medium, at least 2 mols. of the sulphur containing reaction components being used for each mol. of antimony trihalide or trioxide.  The structure of the compounds is not known but analysis shows that they contain in bowed form either 2 mols. of thioglycollic acid or 1-mercapto-2-hydroxyalkanes or 1 mol. each of 1-mercapto-2-hydroxalkane and thioglycollic acid for each antimony atom.  The stabilizers may be added during polymerization or during subsequent treatment of the polymer, e.g. on a roller. Examples illustrate the use of compounds A-D prepared by reacting antimony trioxide with (A) a mixture of thioglycollic acid and mercaptoethanol, (B) mercaptoethanol, (C) a mixture of mercaptoethanol and mercaptopropanol, and (D) a mixture of thioglycollic acid and mercaptopropanol.ALSO:Organic antimony compounds are prepared by reacting an antimony trihalide or antimony trioxide with thioglycollic acid and/or with at least one 1-mercapto-2-hydroxyalkane in an aqueous medium, at least 2 mols. of the sulphur containing reaction components being used for each mol. of antimony trihalide or trioxide. When using 1-mercapto-2-hydroxyalkanes the reaction is preferable carried out in a neutral or alkaline aqueous solution, antimony trioxide advantageously being used as the antimony compound.  The reaction with thioglycollic acid may also be carried out in an acid medium, antimony trichloride being the preferred antimony compound.  The reaction may be carried out in the temperature range of 0-100 DEG C., preferably 60-100 DEG  C.  The structure of the new compounds is not known but analysis shows that the compounds contain in bound form either 2 mols. of thioglycollic acid or 1-mercapto-2-hydroxyalkane or 1 mol. of each of 1-mercapto-2-hydroxyalkane or thioglycollic acid per antimony atom.  The compounds are used as stabilizers for chlorine containing polymers.
