Title: Improvements in and relating to the coating of surfaces
IPC: B05D7/26
Filed: 1941-05-15
Abstract: 551,309. Coating surfaces. NEWTON, CHAMBERS & CO, Ltd., and TUCKER, R. C. May 15, 1941, No. 6281. [Class 95] In a process of coating an article by means of a number of superimposed protective layers, the outermost protective layer is a thermo-setting synthetic resin, at least one other layer, not adjacent the article, is a filled thermo-setting synthetic resin lacquer, and there are two unfilled thermo-setting resin lacquer layers adjacent one another. Baking between the application of successive layers, to an extent sufficient to remove solvents, is avoided, and any heat treatment before the outermost layer has been applied is limited to that which is insufficient to convert the thermo-setting resin which has been used. The filler used in the filled layer is to be physically or chemically active, and specified fillers are carbon black, colloidal clay, oxide of antimony, zinc chromate and oxide of manganese. The temperature of treatment prior to the application of the outermost layer is generally not greater than 120‹C. but the final baking of the completed coating may take place at higher temeratures, e.g. at 140-170‹C. Examples are given in which layers of phenol-formaldehyde resins are used, some of which may contain polyvinyl resins also. The process may be used to provide completely new coatings, or may be applied to the patching of a phenol-formaldehyde resin coating which is damaged or defective.

Title: Frequency synthesiser
IPC: H03L7/197
Filed: 1968-02-08
Abstract: 1,143,896. Automatic frequency control systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 Feb., 1968 [11 Feb., 1967], No. 6282/68. Heading H3A. An automatic frequency control system wherein the frequency of an oscillator 1 is stabilized at a desired multiple of the frequency of a reference oscillator 8 by means of a variable divider 3 and a phase discriminator 9, is provided with means for interpolating between harmonics of the oscillator 8 by periodically adding or blocking pulses to the divider 3 or by periodically varying the division ratio. In Fig. 1, the output of divider 3 is fed via an amplifier 13 to a ten-stage shift-register 12 controlled by an adjusting switch 15 to produce an output pulse after each n input pulses, where n is set by the switch 15. Each output from the shift-register blocks a gate 14 for one input pulse, thereby effectively altering the division ratio of the divider 3. In this way the frequency of oscillator 1 can be varied from 20-70 mc/s in steps of 0-01 mc/s. when the frequency of oscillator 8 is 0À1 mc/s. The first three digits are set by the controls 5-7 of divider 3, and the last digit by the switch 15. In a modification, Fig. 3 (not shown), the output of amplifier 13 feeds a pulse commutator (16) which distributes the input periodically to ten parallel output lines each including a gate (27-36) controlled by an adjusting switch (37). The outputs of the gates are fed to adjusting means of the divider 3 to vary its division ratio by one unit.

Title: Variable-throw crank mechanism for feeding metal stock to punch presses
Inventor: BUDLONG SIMEON
IPC: B21D43/09
Filed: 1958-02-27
Abstract: 852,376. Feeding metal strip. LITTELL MACHINE CO., F. J. Feb. 27, 1958, No. 6370/58. Class 83 (4). [Also in Group XXIV] In adjustable crank mechanism for reciprocating a rack 37, Fig. 1, driving the feed-rolls of a punch press, the rack is secured to a member 62 journalled on a collar 57, Fig. 3, which encircles, but is spaced from, a sleeve 51 on a crank-pin or trunnion 45 projecting from the face of a plate 38 mounted on a driving- shaft 21, the collar 57 being radially adjustable relatively to the trunnion 45 by rotation of a remote control wire 103 to effect small adjustments in the stroke of the rack during operation thereof. The rack 37 operates through a one-way clutch 33 to rotate intermittently the rolls 23, 24 feeding metal strip to the press. The radial position of the collar 57 is determined by pins 65, 66 whose inner ends engage an inclined portion of an axially-movable adjusting-pin 50, the pin having cylindrical end-members slidable in a bore in the trunnion 45. The pin 50 is coupled by a universal link to a plunger 90 in screw-thread engagement with the shank of a bevel gear 81 rotatable in a housing 80 carried by the member 62. The gear 81 is engaged by a pinion 110 coupled to a flexible control wire 103 rotatable by a hand wheel 104, Fig. 1. Rotation of the wheel 104 shifts the threaded plunger 90 and pin 50 to cause radial displacement of the pins 65, 66 supporting the collar 57, the collar being thus adjusted between concentric and eccentric positions relatively to the trunnion 45 so that the stroke of the rack 37, and thus the rotation of the feed rolls 24, 25, may be adjusted while the press is operating. In order to avoid undue loading of the pins 65, 66, Fig. 5, supporting the collar 57, lateral forces between the collar 57 and trunnion 45 are absorbed by a pair of thrustplates 74, 75 mounted in grooves in the collar 57 and engaging flattened sides of the sleeve 51 on the trunnion, the thrust-plates being substantially parallel to the rack. The trunnion 45 is itself mounted for radial adjustment across the plate 38, having a wedge-shaped head 46 engaging an undercut diametral groove 40, Fig. 2, in the face of the plate, adjustment being effected, when the plate is at rest, by rotation of a screw 41 threadedly engaging the head 46. The trunnion is locked in adjusted position by a nut 53 thereon which, acting through the sleeve 51, tightens the head 46 against the undercut sides of the groove 40.

Abstract: 526,031. Rotary classifiers ; ball-and-ring mills. BABCOCK & WILCOX, Ltd., and MONTGOMERY, S. A. March 2, 1939, No. 6915. [Classes 23 and 59] A rotary classifier arranged above a ball-andring mill for the purpose of returning oversize particles, has a number of blades arranged between two annular members and having longitudinally extending pockets or grooves, which trap particles and conduct them downwards. The outer ends of rods 2 radiating from the hub 1 on the shaft 69 carry a ring 3 to which is bolted another ring 5. At the lower end of the rotor, rods 9 carry a ring 11 to which the ring 12 is bolted. The blades 14 are of W-section and are arranged between the rings 5, 12 with the open ends of the grooves facing the direction of rotation. The blades are inclined at about 10 degrees to the vertical and the upper end is in advance of the lower. The inner edge of each blade coincides with the inner edges of the rings 5, 12, and the ring 5 extends across the whole width of the blades while the lower ring 12 extends only as far as the central ridges of the blades as shown in Fig. 2, so that the outer groove of each blade terminates below the upper surface of the ring 12. Fixing plates 17 are riveted to the ring, and part of each plate is bent up and welded to a blade. The pulverizer is of the type described in Specification 523,770 and has a grinding ring 51 with a row of balls 53. Matter is fed down the spout 57 to the inner side of the grinding ring, and the pulverized material from the outer side is entrained in the current of air which flows upwards between the outer surface of the ring and the throat plate 58. This stream flows inwardly between the blades of the classifier 61 which is driven by a motor through gearing 72 and a resilient coupling 71. The heavier oversize particles are trapped in the first groove of the blades and travel down to the inside of the grinding ring, while the next oversize particles are trapped in the second groove and travel down to the ring 12 ; most of the second deposition moves outwards to the edge of the ring and drops to the grinding ring while the remainder drops through the funnel 82 to a container 83 from which it is ejected through adjustable apertures 84. The gas stream passes upwards to the mill outlets 65. The passage between the classifier and the upper plate 63 is sealed centrifugally by the plate 68 and the flange 67.
