Title: Improvements in ball or float valves
IPC: F16K33/00
Filed: 1937-04-27
Abstract: 488,232. Float valves. KING, W. April 27, 1937, No. 12007. [Class 135] A glass ball float is secured to a valveactuating arm by a stirrup clamped by a threaded bolt and nut about a circumferential groove or rib on the ball so as to be capable of angular adjustment yet without increasing the tension of the grip on the ball to an extent likely to break it. In the form shown, the stirrup is in two parts d<1>, d2 having bent portions c secured by a square-headed bolt and wing- nut k to a lug f on a socket f screwed to the valve arm g. In a modification, the stirrup is formed in one piece and has opposite the bent ends a portion of reduced width which is slightly bent outwardly. The glass ball may be in one piece, or may be formed of two pressed glass hemispheres joined together as by screwing, in which case the circumferential groove will extend at right-angles to the joint. A rubber buffer may be secured to the ball.

Abstract: 704,174. Making bearing shells. CLEVITE. Ltd. May 23, 1951 [May 27, 1950], No: 2067/51. Classes 83 (2) and 83 (4) In making flanged bearing shells a flanged blank comprising a steel sheet 15 with a bearing metal coating 16, is bent about a roll 21 while the flanges are compressed by a roll 20. A blank 15 is fed by a fluid-operated member 55 to a roll 21 and is engaged by a gripper 45 actuated by a cam-shaft 48 axially moved by fluid pressure. Recesses 40, 41 in the roll 20 engage the flanges 17. The roll 20 is lowered and locked by fluid pressure mechanism and the rolls are rotated to bend the blank about the roll 21 and to compress the flanges. The roll 20 is rotated faster -than the roll 21 in order to effect a burnishing action on the flanges. At the end of the bending operation a stop 60 engages pins 47 to eject the blank.

Abstract: 575,498. Wire fabrics. POLLITT, H. W. W. June 26, 1944, No. 12108. [Class 45] [Also in Groups X and XXV] A clip for securing stout wires or rods together in closelyspaced parallel relationship, for example, the wires of two separate sheets of open meshed metal fabric, comprises a pair of limbs 1, 2, Fig. 3, having ramps 3, 4, both ramps being adapted to ride over one of the wires or rods 5, 6 to be secured together, the limbs being relatively staggered so that a space is left between them which allows the clip to be passed freely over the two wires, in the position shown in Fig. 2. On rotating the clip about an axis parallel to the limbs into the position in Figs. 3 and 4, the lower wire rides over the ramps 3, 4. Angled leads 7, 8, Fig. 7, may be provided on the ramps 3, 4. The virtually closed loop formed by the clip is of such a width as to accommodate one wire, and of length to accommodate one more wire than the number to be in fact accommodated. The clip is rigid, and may be made of stout sheet metal from a flat blank.

As shown, the fixing flanges 18, 19 are so disposed that, in clamping the diaphragm they set up a bending stress in the portion 16. When in its stress-relieved condition 23 (shown in broken lines) the angle a is greater than the angle #. Alternatively, Fig. 2, the diaphragm may be stressed upon installation by bending it from the position shown by broken lines to that shown by full lines so that compressive stresses are set up in zone 20<SP>1</SP>. In these arrangements during a braking operation, the diaphragm is acted upon by compressed air to move it with the plunger 10 from its rest position in the direction of arrow 21 to the position shown by broken lines 23. The diaphragm may be provided with a reinforcing insert 28 and the periphery in cross-section may be circular or flared and provided with sealing beads (29, 30, Fig. 2).

A resilient tamper-proof cap has a skirt 10 with an internal annular bead 16 at its free end which engages a groove in the neck of the container, and a ring 34 joined to the skirt 10 by an integral hinge 36 and at least one integral frangible portion 38. The shoulder 22 defining the lower wall of the groove in the bottle neck extends beyond the annular skirt and so prevents the cap being removed manually by prising the rim. The cap is opened by breaking the portions 38 to release the ring 34 which can be hinged away from the skirt and used as a pull-ring to raise the cap. An annular ridge 29 depends from the inside of the cap top 24 and seals against the inside of the rim 30. The ridge 29 and the skirt 14 define a groove 28 so that an annular space remains, to aid in vacuum sealing, when the rim 30 is seated.

Abstract: 1,110,046. Photo-sensitive material. MINNESOTA MINING & MANUFACTURING CO. April 27, 1965 [April 27, 1964], No.12762/65. Heading G2C. A photo-sensitive layer comprising a silver salt of an organic acid containing therein a catalytic amount (as defined) of a silver halide formed from the silver salt, is developable by heating between 90 to 150‹C. in the presence of a mild reducing agent (as defined), which may be in the photo-sensitive layer. Positive images may be prepared by contacting a developed layer containing a volatilizable reducing agent with a receptor sheet comprising a uniformly exposed photosensitive layer of the invention not containing a reducing agent, and heating to effect transfer of unused reducing agent to the receptor sheet and reaction with the silver salt therein. The mild reducing agent may be hydroquinone methylhydroxynaphthalene, methyl gallate, catechol, phenylenediamine, p-aminophenol and 1-phenyl pyrazolidone, and the organic acid may be a C 14-22  fatty acid. The silver halide may be formed by treating the silver salt with a gaseous hydrogen halide, or an aqueous solution of a metal halide or an ionizable organic halide (e.g. a sensitizing dye). The photo-sensitive layer may be supported and contain binders, organic acid stabilizers, sensitizing dyes, desensitizers (e.g. benztriazole and phenyl-mercaptotetrazole) and whitening agents (e.g. ZnO and Ti0 2 ).
