Title: Pneumatic chuck
Inventor: BENJAMIN MILTON LLOYD
IPC: B23B31/20
Filed: 1959-06-12
Abstract: 860,927. Chucks. ERICKSON TOOL CO. June 12, 1959, No. 20220/59. Class 83 (3). In a pneumatic chuck, the collet is operated by a sliding-sleeve actuated by levers rocked by a piston, the mechanical advantage of the levers increasing to a maximum at the final clamping-position. The chuck comprises a plate 2, Fig. 1, and a cylinder (i secured together by screws, and an adaptor 20 rotatably supported in plate 2 by a bearing 3 and in a piston 11 by a bearing 14. The adaptor 20 may be connected to a machine-spindle at either end, carries a coaxial slidable sleeve 30 which, when moved by the levers 32, actuates a collet in the adaptor 20. In operation air is supplied through a port 10 and moves the piston 11, seal 12 and a ring 23, to the left, thus moving the levers 32 from the solid-line-position, Fig. 4, to the dotted-line-position. Since the adaptor 20 is fixed axially, the ends 33 of the levers 32 move the sleeve 30 to the right, thus operating the collet in the gripping-direction. The moment-arm 52 will remain constant, but the arm 53 will decrease and the mechanical advantage of the lever will be greatest when the work is finally gripped by the collet. The levers are pivoted about pins 37 in slots 41 in a retaining-ring 40 and adaptor 20, and the pins are axially-movable in the slots. To release the collet, the air is vented through the port 10, and springs 48 move the piston to the right and springs 47 return the levers to their initial position. The mechanism is lubricated and cooled by an oil-air mixture, fed through a port 61, and the chuck-body is held stationary by a rod screwed into the hole 16. In a modification, the sleeve 30 is replaced by a sleeve coaxial with, but external to, the adaptor, which is moved axially by the heels of the levers 32, and a collet is incorporated with the sleeve and adaptor. The springs 47 are replaced by springs which urge the sleeve to the right directly. In a further modification, the bearings are dispensed with, and the chuck body is secured to and rotated with the adaptor.

Filed: 1968-05-01
Abstract: 1,221,349. Coating by hot-dipping. ARMCO STEEL CORP. May 1, 1968 [May 10, 1967], No. 20599/ 68. Heading C7F. Ferrous metal strip is coated with molten metal by (a) cleaning the surface of the strip and bringing its temperature to that of the molten coating metal (b) passing the strip through a bath of molten coating metal and withdrawing it in a generally vertical path of travel (c) impinging a substantially laminar flow jet of gaseous fluid on the surface of the strip as it emerges from the bath at a height where the thickness of the coating metal is in excess of the desired final coating thickness, the impinging jet returning a continuous flow of the molten metal to the bath while a desired quantity of molten coating metal adheres to the strip and (d) contouring the narrow dimension of the gaseous jet across a portion thereof so as to proportion the wiping effect and leave a uniform coating thickness across the entire width of the strip. For instance, bowing of the strip is compensated for by widening the nozzle across part of its length, this being achieved by using a nozzle of the kind described in U. S.A. Specification 3, 314,163. The maximum velocity of the jet should be at the point of exit from the nozzle, and there should be a sharp velocity gradient across the narrow dimension of the jet, to avoid turbulence and consequent distortion of the coating, which may be of Zn, Al, or terne.

[Also in Division H4] In a system in which attitude deviations of an unattached body relative to an external source of radiation are automatically corrected, the deviations are detected by a device which produces signals, variable with the angle of incidence of radiation, which are further modified by masking means in dependence on angle of deviation. Fig. 1 shows an air-pressurized portion 1 of the nosecone of a space rocket provided, at 90‹ intervals round its circumference towards the rear, with sunlight sensitive units 5 which control valves 4 associated with a compressed nitrogen bottle 2 so that jets Issuing from nozzles 3 are controlled in an on-off manner to maintain the axis of the nose-cone at a desired attitude relative to the sun. Each sunlight sensitive unit 5, which has a cover 10 thrown off when the nose-cone separates from its booster, comprises (a) a photocell 6, responsive to light from a forward direction over a wide angle, associated with a shadow mask 11 so shaped that the photo-cell output is a square root function of the attitude deviation, (b) a photocell 7 responsive to light from a rearward direction over a wide angle, and (c) a photo-cell 8 associated with a prism 9 to be responsive to light from a forward direction over a narrow angle. As shown in Fig. 2, the combined outputs of photocells 6 and 7 control jet valves 4 through a threshold unit 13 and a power amplifier 14. A rate of turn signal from a gyro 17 is added through a noise filter 16. Drift is avoided by applying the outputs of photo-cells 8 through an integrator 12 which is only rendered effective when sunlight falls on photo-cells 8. When the resultant control signal exceeds the threshold of unit 13 a jet is produced in the appropriate direction to correct the attitude and feedback is applied through an integrator 18. The electronic control gear is contained in a housing 15 which is cooled by the fall in pressure of bottle 2.
