Abstract: 822,058. Grinding wheels. SUPER-CUT Inc. Nov. 1, 1956, No. 33416/56. Class 60. A grinding wheel for grinding a flat piece of glass, marble, etc., comprises a plurality of concentrically-arranged annular members 9, 10, 11, Figs. 1 and 4, secured to the outer face of a disc-like body 8 and provided with abrasive facings 24, 37, 43 which have their peripheral edges shaped so that the facings are of progressively-increasing radial width from their outer to their inner faces ; the outer faces of the facings of respective annular members are arranged in steps with the face of the outermost facing 9 nearest to the body 8. The body 8 is made of metal and formed with annular ribs providing grooves 19 for the reception of the annular members 9, 10, 11 which are of steel, brass, bronze, &c. and each constituted by a series of spaced arcuate segments. The abrasive facing 24, 32, 42 on each segment consists of a matrix with embedded diamond or other abrasive particles soldered or otherwise fixed to the segment; the mesh of the abrasive particles may be the same or be of progressively decreasing size from the outer-most member 9 to the innermost member 11. The gaps between the arcuate segments of each annular member 9, 10, 11 are staggered in relation to those of the adjacent member. The operative faces of the facings may be flat, convex or rounded, and their radially outer edges are bevelled in order that they may be of progressively greater radial width from the operative faces to their bases ; the radially inner edges and the end edges of the facings may be similarly bevelled. Screws 25 engaging with the arcuate segments permit the adjustment of the axial spacing of the operative abrasive faces from the body 8, and other screws 26 are used to lock the segments in their adjusted position. Coolant of low surface tension is fed to the grinding face from grooves 45, 48, 51 in the rear face of the body 8 through inclined holes 46, 49, 52 respectively arranged so that their outlets discharge radially inwards of the annular members 9, 10, 11 ; the disposition of the grooves, holes and ribs 14, 16, 18 forming the inner walls of the grooves 19 is such as to aid the flow of coolant due to centrifugal force. The coolant also serves to clear abrasive particles and products of abrasion from the grinding faces. The thickness of the abrasive facings is arranged to be at least as great as the respective grinding depths. Instead of providing the wheel with three annular rings 9, 10, 11 it may have two such members or more than three.

Abstract: 366,921. Electric synchronous movements. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York,U.S.A. -(Assignees of Chesnut, R. W. ; 155, Inwood Avenue, Upper Montclair, New Jersey, Fisher, H. J. ; Davis Road, Port Washington, and Sanial, A. J. ; 365, West 20th Street, both in New York, both in U.S.A.) Nov. 7, 1930, No. 33560. Con. vention date, Nov. 8, 1929. [Class 40 (iii).] In a secret telephone transmission system the secrecy scheme is varied periodically under the control of cams driven by a synchronous motor 72 driven by a valve oscillator 70. When it is desired to check the synchronism, keys 120 are operated at both stations and a 1000-cycle generator is connected up at the controlling station. This results in the transmission of a signal from the controlling station {at which strap 19 is omitted) during the half second that 75 makes its upper contacts. At the controlled station (at which strap 170 is omitted) the circuits are fit to receive while the cam 74 makes its lower contacts. Consequently if the cams are synchronous, no signal is heard. The cams are brought into synchronism by means of the apparatus shown in Fig. 5.

Title: Hydraulic pressure bottle testing method and machine
IPC: G01N3/12
Filed: 1973-07-13
Abstract: 1424901 Pressure testing bottles AUTOMATED MACHINE SYSTEMS INC 13 July 1973 [17 July 1972] 33610/73 Heading G1S Bottles 27, Fig. 1, are enclosed by a lowered honeycomb carrier 25 and moved along a test table 24 by reciprocating shafts 30 releasably engaging ears 28 on the carrier. At position B the bottles are quick filled with water from spouts 32 and are then moved by 30 to position C for slow topping off. At station D the bottles are each subjected to an axial load from a press platen and internal pressure, at station E broken bottles are discarded, and at F sound bottles are deposited on a take away conveyer and the carrier 25 is lifted up and conveyed back to the start. The arrangement of Figs. 3 and 4 (not shown) illustrate how the hydraulic internal test pressure is built up in each sound bottle as platen 47 descends and valves (51) are opened. After the test, the test heads (48) are raised from the bottles which are then moved to the disposal station E. At this station bottle neck chucks 64, Figs. 5-7 (not shown) grip the sound bottles, or release the broken bottles. All of the sound bottles which have withstood the internal hydraulic pressure and axial loading remain filled with water but a faulty bottle allows its piston (100) to move downwardly to drive rods (106, 107) down to open the chuck and release the bottle. Defective bottles fall through a trap 24 into a bin 125 whilst sound bottles are moved with their carriers 25 to station F. In a modification, instead of moving the bottles in carriers they are randomly placed on a feed conveyer 126, Fig. 9, and passed between longitudinally extending parallel fingers which have guide strips and line the bottles into columns. As the shaft 30 reciprocates, sets of locating pins (128, 138) are raised vertically between the bottles Figs. 10, 11 (not shown) and the bed blocks supporting the bottles are expanded by retraction of a piston (141) Figs. 12, 13 (not shown). This action segregates and uniformly spaces the bottles at station A after which carriers 25 are lowered and moved to carry the bottles to the first filling station B as before.

With the stop 27 in the position shown the valve 10 becomes seated and the valve 11 unseated on engagement of the valve spring 21 with the stop 27, thereby confining pressure air from the inlet 9 to the cylinder 1 and exhausting the cylinder 2 to atmosphere through a duct 17 and ports 18, 20 to effect reversal of stroke. On unscrewing the cap 30 the piston 3 engages the stop 25 without the valve 10 closing, thus retaining air pressure against both pistons 3, 4 which results in them remaining in a parked position.
