Title: Method of, and apparatus for, accurately forming the peripheral contour of a diamond-impregnated grinding wheel
IPC: B24B53/08
Filed: 1956-06-01
Abstract: 786,718. Trueing grinding wheels. NATIONAL CASH REGISTER CO. June 1, 1956 [June 17, 1955], No. 16942/56. Class 60. The peripheral contour of a diamondimpregnated grinding wheel 10 is formed by first shaping this contour in reverse on a dressing wheel 24 and then bringing the latter wheel while it is rotating at relatively low speed into contact with the diamond wheel which is rotating at a relatively high speed. The dressing wheel 10 is mounted on a bracket 12 on a column 9 for drive by a motor 13 when used for grinding and by a motor 18 through a reduction gear and belt drive 14 when it is being dressed by the wheel 24 ; the periphery of the grinding speed of the wheel 10 has a grinding speed of over 3,500 feet per minute and a dressing speed of between 600 to 2,000 inches per minute. The dressing wheel 24 is mounted on a block 26 for vertical adjustment on a column 27 on an adjustable slide 28 on a worktable 19 arranged for reciprocation to and from the diamond wheel. Also mounted on the slide 28 is a pantograph mechanism 23 for converting the movements of a tracer stud 35 over a template 36 into movements of a diamond dressing point 36<SP>1</SP> for forming the periphery of the dressing wheel. While the dressing wheel is being so formed, it is rotated by a motor 22 through a belt drive 32, its peripheral speed being more than 6,000 feet per minute. After formation of this wheel, the dressing point 36<SP>1</SP> is withdrawn, the motor 22 de-energized and belt 32 loosened, the dressing wheel driven from a motor 41 through reduction gearing and a friction drive, the drive of the diamond wheel 10 effected by the motor 18, and the worktable 19 then advanced to bring the peripheries of the wheels 10, 24 into contact. The periphery of the dressing wheel has a speed for this operation of between 1À2 to 3À2 inches per minute and the period for which the two wheels are in contact may be represented by only a part revolution of the dressing wheel. Preferably, the diamond wheel is rotated at a speed between 500 to 630 times faster than that of the dressing wheel.

Title: Improvements in or relating to the manufacture of bricks and the like
IPC: B28B7/00
Filed: 1920-06-22
Abstract: 170,622. Brettschneider, F. June 22, 1920. Presses processes; moulds.-A process for moulding bricks free from internal tension consists in filling a mould 10 with slight excess of plastio material and raising it upwards by means of an eccentric 4 whilst allowing excess material to escape between the edges of the mould and the stationary oover-plate 6, until contact with the cover-plate prevents further escape of material, such excess as remains escaping through holes 15 in the movable bottom plate 3. The cover-plate 6 is adjustably attached to the framework 1 by hinges 7, and is held in position by adjustable hooks 8. The mould 10, Fig. 4, comprises halves 12 movable about hinges 11 by handles 14, and is made cone-shaped outwardly to correspond with the frame 9. In an alternative form, both the upper and the lower edges of the mould are provided with projecting steel plates so that the mould may be reversed when worn. Specification 18786/03 is referred to.

Title: Improvements in or relating to the manufacture of shoes
IPC: A43D15/00
Filed: 1925-07-02
Abstract: 236,566. British United Shoe Machinery Co., Ltd., (Assignees of Goddu, G.). July 3, 1924, [Convention date]. Machines using continuous wire. - Two parts of a shoe, for example an upper and insole, are united by a fastening which is anchored in them and which without having emerged from them, is curved back towards that face of them which it entered. The invention is described as applied to a step-by-step lasting machine of the kind described in Specification 228,578. The work rest 150 therein described is replaced by a roughened rest 4 which co-operates with a gauge member 6 to position the work. A staple-bend.- ing device comprises two members 10 pivoted to the staple-guiding nose 8 so as to move therewith, and provided with notches 18 positioned in the line of drive of the staple legs c. The latter are progressively curved, in planes perpendicular to the staple head, by these notches ,as they enter the work, so that the points are finally curved back towards the entering face. The members 10 are independently adjustable by setscrews 20, 22 in order to vary the final degree of curvature of the legs. The machine employed need not make its own fastenings, and is par ticularly suitable for uniting an upper b, as it is lasted, to an intact or unchannelled insole a in McKay shoe work. In this case, an outsole is attached to the upper and insole by a through and through seam lying just outside the line of staples. Specifications 6724/96, 20126/07, and 230,121 also are referred to.

Abstract: 658,912. Drying paper. MESSINGER, W. June 27, 1949, No. 17012. [Class 96] [Also in Group XIII] A heated cylinder for drying paper comprises an outer casing 10 and an inner shell 11 mounted on a shaft 22, helical grooves 12 being cut in the outer surface of the shell to form steam passages. Steam is delivered to the grooves 12 by radial steam pipes 30 connected to an axial steam delivery pipe 31, these pipes 30 extending through the walls of the shell 11 and terminating in annular channels 40 formed in the surface of the shell and which cut into the helical grooves 12. Discharge of the steam from the grooves is effected by a number of radially-drilled holes 46 leading to the interior of the shell, the surface of which is formed as a series of axial Vs. The water of condensation flows into the bottom of the V's whence it is removed through discharge pipes 50, each of which is curved to facilitate discharge towards the axis of rotation.

Abstract: 828,143. Seaming rollers. METAL BOX CO. Ltd. May 30, 1958, No. 17446/58. Class 83 (4). A seaming roll for securing the ends on can bodies comprises a rotatable spindle 13, a peripherally grooved annular element 1 supported for rotation with said spindle and for lateral movement relative thereto in a direction at right angles to the axis of the spindle, and locating means tending to maintain said element concentric with said axis. The roll is provided with first and second seaming grooves 11 and 12 respectively. The roll locating means comprise a washer 14, located between the annular element and the spindle and balls 15 seated between the opposite sides 16, 17 of the annular elements and resilient annular plates 18, 19 which are stressed to converge towards the spindle for urging the balls into their seats. In operation, while the seaming pressure remains constant, the annular element remains concentric with the spindle axis and when such pressure becomes excessive the pre-loading of the plates 18, 19 is overcome so that the balls ride partially out of their seats and permit lateral movement of the annular element thus maintaining the seaming pressure constant.

Title: Improvements in and relating to the manufacture of sand paper or like composite structures
Filed: 1923-02-06
Abstract: A flexible and waterproof adhesive is in the form of a varnish prepared from linseed oil or china wood oil and a gum, for example, dammar, kauri, or copal, and to which a drying-agent, operating outwardly, for example, borate of manganese, is added. To accelerate the drying from the outer surface inwardly, and to improve the adhesive properties, electrolytic process white lead, known as "Dowdy white," is added; a paste dryer, for example, lead acetate and resinate of manganese also may be employed. When the adhesive is required to be more fluid, a japan drier is used, for example, "schrack japan."  In preparing the varnish, the oil is boiled until it reaches nearly a solid state, and the varnish may comprise three parts of gum dammar with two parts of linseed oil.  Castor oil may be added when the drying action is to be retarded.  Specification 194,274 is referred to.
