Title: Abrading machines
Inventor: ASHWORTH STEWART IVES
IPC: B24C3/06
Filed: 1963-02-27
Abstract: 1,070,233. Cyclone separators. ABRASIVE DEVELOPMENTS Ltd. Feb. 25, 1964 [Feb. 27, 1963; Nov. 9, 1963; Nov. 15, 1963], Nos. 7808/63, 44305/63 and 45178/63. Heading B2P. [Also in Division B3] Spent abrasive and detritus from a blasting chamber 10 pass through a suction tube 20 to a first cyclone separator 22. This is of conventional form having a rubber lining and is deliberately made relatively ineffective so that only the reusable abrasive is separated, the shattered abrasive and detritus passing to a second cyclone separator 24 of a high reentrant type which operates under a farily high vacuum. The shattered abrasive and detritus from the cyclone 24 pass through an intermediate box 26 to a collecting box 27, the inlet to which is offset from the vertical axis of the cyclone 24. Air from the cyclone 24 passes through an adjustable valve 30 to a multi-stage centrifugal fan 31 which produces the suction. Reusable abrasive separated in the cyclone 22 passes through upper hopper 33, flap valve 44, middle hopper 35, flap valve 45 and lower hopper 37 into an adjustable metering tube 39 extending into a recess 18 in an input pipe 16 through which air is drawn by the suction. The lower hopper 37 has apertures 46 in its well so that it is always at atmospheric pressure. When a valve 41 is open, the middle hopper is at atmospheric pressure; valve 44 is held shut and abrasive builds up in upper hopper 33; any abrasive in middle hopper 35 opens valve 45 and passes to lower hopper 37. When valve 41 is closed, middle hopper 35 is at the same pressure as upper hopper 33; any abrasive in upper hopper 33 opens valve 44 and passes to middle hopper 35; valve 45 is held shut. The valve 41 is alternately opened and shut by cycling means.

IPC: F16J13/00
Filed: 1955-03-17
Abstract: 765,040. Closures for resisting fluid pressures. SHEPHERD, G. R. (Westinghouse Electric International Co.). March 17, 1955, No. 7819/55. Class 123 (1). A high pressure container, for example of stainless steel, consists of a cylindrical shell 51 having a screwed closure 121, Fig. 1, the latter being formed with an annular, resilient, arc-section flange member 123 which is downwardly turned to bridge the joint between the closure and shell and which is welded around its lower edge to the shell, the weld 125 providing the pressure seal. In Fig. 2 the resilient member consists of a semicircular section ring 141 respective edges of which are welded at 143 to the closure 131 and at 145 to the shell 51. Owing to the resilience of the flange 123 and the ring 141 the small movement occurring between the shell and closure when the container is put under pressure is absorbed and is not communicated to the sealing weld.

Filed: 1947-03-22
Abstract: 631,399. Calculating-apparatus. FERRANTI, Ltd., and TAYLOR, M. K. March 22, 1947, No. 7924. [Class 106 (i)] [Also in Group XXXVIII] In a product computing instrument two input voltages x, y, at least one of which is A.C., cause mechanical vibrations in a rod which generate an output voltage z in a pick-up, proportional to the product x, y, which is independent of the phase of the A.C. The x and y input voltages 2, 5 are fed to a dynamometer movement having its moving coil 1 mounted for torsional oscillation on a rod 10 resonant at the vibration frequency of the coil. The rod is supported at a nodalpoint 11, and carries at its other end a pick-up coil 12 which is vibrated between the poles of a permanent magnet 14 to generate a voltage z proportional to the intensity of vibration, and hence the product of the dynamometer input voltages, which is indicated on a voltmeter or passed to another calculator. A piezo-electriccrystal may be used instead of the pick-up coil 15. In an alternative construction (Fig. 2, not shown) the input voltages cause one arm of a tuning fork to vibrate and the pick-up is connected to the other arm.

Abstract: 477,741. Automatic couplings for vehicles. NATIONAL MALLEABLE & STEEL CASTINGS CO. March 19, 1937, No. 8154. Convention date, March 28, 1936. [Class 103 (v)] Car couplers of the bottom operative type employing a pivoted rotor lever 20, Fig. 1, connected to a lock 2 by a link 10 are provided with means 12 on the link whereby contact between a knuckle thrower 3 and the link is positioned a maximum distance from the pivot point of the knuckle thrower. The knuckle thrower is also supported and guided during movement to assure adequate lockset and smoother working. Anticreep means 29, 30 and disengaging means are also provided. The knuckle is indicated at 1. A leg 4 of the lock 2 has a projection on the knuckle side of the look with a seat 7 resting on the thrower 3, Fig. 4, in the lockset position. A trunnion 8, Fig. 1, on the leg 4 enters a slot 9 in the link 10 which has an enlarged portion 11 nearly filling the opening 5 in the coupler. The link 10 is pivoted to a lever 20 pivoted to a coupler at 22. An element 25 engages the lever 20 as shown and is operated by the usual uncoupling rod 28 and bail 27. To prevent creep a lug 29 is provided on the coupler to engage a foot 30 on the leg 4 of the lock 2. Upward movement of the lever 20 forces the trunnion 8 along the slot 9 to disengage the members 29, 30. Further upward movement puts the parts in the lockset position. In Fig. 2, where the coupler is locked, an extension 34 on the thrower is seen resting in a recess 33 preventing tipping and disengagement of a trunnion 35. In Fig. 5, the parts have moved upwardly until a pivot 36 of the lock has engaged a ledge 37 in the forward part of the coupler. At this time a surface 12 of the link engages the thrower 3. Further upward movement tilts the locking member as in Fig. 6, decreasing slip between the link 10 and the thrower. In a modification, Fig. 10, the link 41 has a rear portion 42 engaging a surface 43 on the coupler to prevent creep.
