Title: Improvements in extensible chain for use in expanding bracelets and the like
IPC: A44C5/08
Filed: 1926-01-22
Abstract: 258,469. Timings, F. C. Jan. 22, 1926 Bracelets.-An expansible curb chain for bracelets and the like is made up from a number of similar links each comprising elements or halves of U or similar shape slidably connected together to permit of lengthwise extension and contraction. In the form shown in Fig. 2, each link is composed of two elements A, B, each comprising two tubular parts a<1>, a<2> pivotally connected together in parallel but different planes. The two elements forming a link are connected together by double-headed studs c<2> so as to slide relatively to one another against the action of springs e bearing against the studs c<2>. Fig. 5 shows an alternative form, in which the two parts A, B forming each link are kinked or twisted at a<3>, b<3> respectively to dispose the limbs of the links in parallel planes. The elements of the links may be slidably connected together by connector devices, as shown in Fig. 6, comprising two interconnected slides o, p. These devices after assembly with their associated springs are inserted in the tubular elements of the links, the ends o', p' of which and the material adjacent the slots in which, are then closed in to retain the devices in position. In a further form of chain shown in Fig. 10, the elements A, B, which are similar to those shown in Fig. 5, are slidably connected by means of plungers connected to rods passing out through the end of one element and connected to the other element, the springs being compressible between the plunger and the end of the element.

Title: Diffusion coating of a ferrous article
Inventor: WEATHERLY ERIC GEORGE
IPC: C23C10/34
Filed: 1959-01-19
Abstract: A ferrous article is coated with another metal by halide diffusion in the presence of a substance such as ammonium nitrate which generates nitrous oxide upon heating to the diffusion temperature.  Coating may be effected in the following ways: (1) by packing the article in a composition comprising sand, the coating metal or a halide thereof, ammonium nitrate, and one or more ammonium halides and then heating; (2) by coating the article with a solution containing ammonium nitrate together with one or more ammonium halides, surrounding the article with a sand/coating metal mixture, and then heating; (3) by coating the article with a suspension, solution or dispersion containing a coating metal halide and ammonium nitrate with or without ammonium halides, and then heating; or (4) by covering the article with a carrier impregnated with a suspension, &c., as in (3), and then heating. Specified coating metals are chromium, vanadium, manganese, niobium, tantalum, tungsten and aluminium.  If desired, the coated article may be coated with aluminium by applying aluminium chloride and heating.  Diffusion is effected in a box which is sealed with a composition which forms a liquid glass at diffusion temperature and is saturated with respect to the coating metal.

Title: Improvements in or relating to valves for filling containers with liquids from a reservoir
IPC: F16K31/58
Filed: 1948-01-22
Abstract: 646,470. Bottling. CHERRY-BURRELL CORPORATION. Jan. 22, 1948, No. 1983. Convention date, May 4, 1942. [Class 125 (ii) ] A valve for filling containers, e.g. milk bottles, from a reservoir 10 comprises a vent tube 13 formed at the bottom with a valve-element 14 and supported centrally in an opening 11 by a spider 12 which is positioned by engagement with the sloping walls of the opening, a resilient bulb 33 which is interposed between the bottom of the reservoir and a member 27 having a sleeve 26 which is the movable element of the valve, and a resilient gasket 38 which fits over the sleeve 26 and seals the container as it is filled. Drip edges 37, 39 for condensate are provided on the bulb 33 and gasket 38, and the member 27 is provided with a drip collecting gutter 28 leading to a spout 29. Condensate is excluded from the interior of the bulb by a sealing rib 36. The spider 12 is U-shaped in plan and is made of springy material to clip on to the tube 13 which is held against downward movement by a flange 17 which bears on the top of the spider. In a modification, the spider has a central hub through which the tube 13 passes, a sleeve being interposed between the tube and the hub so that a shoulder on the sleeve bears on the hub to prevent upward movement of the tube, and a spring clip, which engages a groove in the sleeve, bears on the top of the hub and prevents downward movement of the tubes. The walls of the opening 11 and an upward extension of the sleeve 26 may be of curved contour to receive correspondingly rounded upper and lower ends of the bulb 33, a rolling contact between the ends of the bulb and the supporting surfaces being thus obtained when the bulb is compressed axially. The gutter 28 may be formed separately from, and attached to, the sleeve 26. The sleeve 26 may carry upstanding pins arranged in a circle so as to bear against the walls of the opening 11 and prevent transverse movement of the valve parts, and the bulb may have an annular gutter surrounding it to prevent condensate from entering the bottle as it is moved into and away from the filling position. When the bulb is compressed axially, the deformation of the gutter makes the outer edge thereof snap downwardly to discharge the condensate.
