Abstract: 672,386. Centrifugal casting-machines. CENTRAL FOUNDRY CO. March 9, 1950 [March 18, 1949], No. 5949/50. Class 83 (i). Molten metal is poured into a centrifugal mould from a ladle which is tilted by a pneumatic cylinder at a speed which is automatically controlled, according to the position of the ladle itself, by a hydraulic cylinder having its piston secured to the ladle and having a by-pass valve actuated by linkwork connected to and moving with the ladle. A tiltable ladle 10 and a pouring trough 15 are mounted on a wheeled carriage 22 movable by fluid pressure means to and from the pouring position in which the trough projects into a centrifugal mould 16, Fig. 1. Tracks 24 on which the carriage runs are vertically adjustable. The ladle 10 is clamped to a framework 36 which at its forward end has trunnions 35 mounted in side plates of the carriage 22 and at its rear end has two lateral arms 39 to which are secured the rods of pistons operating in vertical cylinders 11, 43. The cylinder 11 is connected to a source of fluid pressure and serves for raising the rear of the ladle to effect pouring. The cylinder 43 contains liquid and its upper and lower ends are connected by a pipe 46 in which is a valve 13 operable by a slotted arm 47 adjustably secured to an arm 48 which is in turn adjustably secured to an arm 52 which moves with the ladle. The valve 13 is thus operated in accordance with the tilting movement of the ladle and the linkages 47, 48, 52 are preferably so adjusted that the rate of tilting of the ladle decreases as pouring proceeds. In casting a 63 pound pipe 4 inches in diameter with a wall thickness of ¢ inch, half the metal would be poured in the first third of the pouring cycle of 3.6 seconds, one-third of the metal would be poured in the second third of the cycle and the remaining one-sixth of the metal in the last third. In order that the valve 13 should not hinder a rapid return movement of the ladle, a by-pass conduit 53 with a one-way valve 54 is provided. Additional liquid can be supplied to the system by a pipe 55 when required. Specification 626,723 is referred to. '

Abstract: 777,001. Mixing apparatus. BOWSER, Inc. March 3, 1955 [March 22, 1954], No. 6364/55. Class 86 [Also in Group I] The supply of filter-aid slurry is controlled during a predetermined portion of a time cycle by means preferably comprising a solenoid valve operated by a process timer. The dial (not shown), of a process timer 27, Fig. 1, is set to that percentage of one complete cycle of the . timer during which it is desired to feed filter aid, such setting effecting adjustment of a movable cam 177 in relation to a fixed cam 175. Where the percentage is 50 or less a selector switch 29 is moved to the upper (28) position so that the circuit of a solenoid-operated control valve 109 is closed by contacts 187 so long as a cam follower 183 engages the gap between the high portions of the cams 175, 177 (which gap may extend for up to half the cycle). Where the percentage is above 50 the switch 29 is moved to the lower (30) position so that the circuit is closed by contacts 189 so long as a cam follower 185 engages the high portion of either cam. While the valve 109 is open some of the liquid to be filtered being pumped (33) from a tank 36 along pipes 48 and 50 to a filter 59 is by-passed along a branch line 72 spanning a throttle valve 47, the branch-line flow being along pipes 71, 75, 91 and 95. Between pipes 75 and 91 is incorporated an eductor (a nozzle-and-venturi device) whose suction connection with a slurry tank 11 is governed by the solenoid valve 109. Thus the feed of slurry is intermittent during filtration. The valve 47 may be replaced by a pump in the branch line. In Fig. 3 (not shown), the pump 33 occupies the position formerly occupied by the valve 47, which is dispensed with. Pre-coating is effected by slurry derived from the tank 11, while in Fig. 1 a separate pre-coat vessel 131 is provided.

Title: Improvements in or relating to transmission gearing for machine tools and other purposes
IPC: B23Q5/00
Filed: 1930-02-28
Abstract: 349,137. Friction gearing. TODMAN, J. C., 29, Goldsmith Avenue, Acton, London, and SHAW, C. R., Stanbury Hempstead Road, Watford, Hertfordshire. Feb. 28, 1930, No. 6705. [Class 80 (i).] In friction gearing for machine tools and other purposes, one or more helical members 3 are rotated from the driving end 4 in such direction as to tend to expand, and are of varying cross section, inner diameter, or pitch along its length so that they expand unequally therealong to bring successive portions into action as the load increases. As shown, the helix 3 is secured to the driving shaft 1, its other end being secured to a loose pin 14 bearing on a thrust ball 15. Radially-movable planet-rollers 5 are carried by the driven shaft 8, and engage with the helix and with a surface 11 on the stationary casing 12. A cap 13 screwing in the casing, or a slidable member, is used to adjust the axial pressure on the helix 3 and thus the frictional pressure between the gearing parts, and such pressure may be so reduced as to stop the drive. When the rollers 5 are of helical form, the frictional driving-contact may be arranged to extend from both ends towards the centres as the load increases. By stationing the shaft 8, the casing 12 is driven in the reverse direction to the shaft 1.
