Abstract: 746,217. Woodworking. LEIRVAG, L. June 2, 1954 [Dec. 3, 1953], No. 16262/54. Class 145 An attachment for a spindle moulding machine, for cutting a rounded tenon 47 on a workpiece 45, comprises a plate 1 having lugs 2 for securing it to the machine, a rotatable disc 4 carrying pair of rails 12, 13 on columns 11 and a carriage' 14 slidable on the rails and carrying a work-holder 39. The work is clamped in the holder 39 by an eccentrically-mounted roller 40 and grooved rollers 15, 17 on the carriage engage the sides of the rails 12, 13, the roller 17 being mounted on a spring-loaded arm 16 pivoted at 18. Spring- or gravity-loaded catches 21, 28 are adjustably positioned on the rails and co-operate with knobs 20, 27 on the carriage to limit its sliding movement to the width of the tenon; a second notch 26 on the catch 21 provides a loading position in which the work is clear of the cutter 46. The workholder is mounted on a member 43 which is adjustable between a pair of lugs 34 by a screw 35 so that the tenon can be formed in the required position across the thickness of the workpiece and which also can be set in an inclined position by screws 38 engaging the rail 13. With the plate 1 attached to the machine so that the axis of rotation of the disc 4 lies on a line spaced from the cutter periphery by half the desired tenon thickness, the carriage is released from one catch 21 and traversed until the other catch 28 is engaged, thus forming one side of the tenon. The disc 4 is then released by withdrawing a spring-loaded pin 6 from a hole 7 in the plate 4 and rotated through 180 degrees until the pin engages another hole 7, thus forming one rounded edge of the tenon. The carriage is then traversed from the catch 28 to the catch 21 and rotated through a further 180 degrees to form the other side and rounded edge. V-guides may be used instead of rails and the rails or guides may be curved. Graduations may be provided for making adjustments for width, thickness and length of tenon.

Title: Improvements in or relating to rammer mechanism for guns
IPC: F41A9/42
Filed: 1936-06-11
Abstract: 479,837. Loading ordnance. GENERAL HYDRAULIC CO. June 11, 1936, No. 16292. Convention date, June 15, 1935. [Classes 92 (i) and 92 (ii)] A loading device for guns comprises a rammer head 13, Fig. 4, connected to a piston 12a working in a hydraulic cylinder 11, a source of supply of liquid under pressure, a pilot valve 9 for controlling the movements of the piston, means such as a handle 18 to actuate the valve to cause the rammer to rani home a shell, and means actuated by the rammer or by the closing movement of the breech-block 22 to cause the valve to move the rammer in the reverse direction. The valve 9, in its neutral position, shortcircuits the liquid supply system which, in the form shown, comprises a tank 6, pump 8, and a motor 7 for driving the pump. The valve is normally held in a position to withdraw the ram by a spring 9a and is depressed to effect the ramming by the handle 18 which is connected thereto by a rod 18a, and pivoted lever 19. It is held in the depressed position by a, spring-controlled latch 17. Towards the end of the ramming stroke a lug 20 on the piston rod 12 trips a lever 21 which lifts a rod 17a connected to the latch, the latter being thus moved to free the valve 9 which is moved by the spring 9a to the ramreturning position. Instead of the lug 20 and lever 21, the rod 17a may be actuated by a pivoted lever 23 which is lifted by a lug 24 on the breech-block 22 as the latter is moving into the breech-closing position. The breechblock, when closed, bears against an arm 19a of the lever 19 and thus prevents forward movement of the handle 18. To prevent firing before the rammer head has returned to a point beyond the range of the recoiling parts, the firing pin 26, Fig. 2, is positively held until the rammer head has passed beyond the rear end of a lever member 25. The pin is held by a lever 27 pivoted to the breech-block and slidably guided in a slot 27c in a spring-urged slide 27a. This slide is held by the member 25 through the medium of a lever 28 until the rammer head, which engages beneath and lifts the member against the action of a spring 28a, has returned to its rear position.

Title: Improved ferrous metal and methods of producing the same
IPC: C21C1/10
Filed: 1958-05-21
Abstract: A ferrous metal, having in the "as-cast" condition a microstructure with carbon in the form of compacted graphite, contains C 1-2.5%, Si 1.5-3.2%, B 0.001-0.05%, the composition of the ferrous metal being such that the metal would solidify as a white cast iron in the absence of boron.  The metal may also contain one or more other elements such as Cr, Ni, Cu, P, Ti, Al, V, Mo, Sn in amounts normally used in cast irons.  One or both of Te up to 0.01 and Bi up to 0.02% may also be present, these two elements, if used together not exceeding 0.02% in total.  The metal may also contain Mn up to 1.15% and S up to 0.5%.  The metal may be produced by melting together steel and white cast iron in quantities such as to give the required C and Si contents, tapping the melt into a ladle at a temperature in the range 2700 DEG F-3000 DEG F, inoculating with B and either Te or Bi or both and pouring at a temperature in the range 2600 DEG F-2750 DEG F into a mould. B may be added in the form of ferro boron, boron carbide, calcium boride, nickel boron, borax or as the element; Te is added as ferro-tellurium, copper-tellurium or as the element, and Bi is added as the metal.  Ductility of the cast metal can be improved by heat treatment e.g. at 1300-1350 DEG F for 3 hours.  The tensile strength is improved by normalizing at 1500-1600 DEG F.
