Title: Protection of piston ring groove walls
Inventor: GHT WILLIAM NELSON WAINWRI
IPC: F16J9/22
Filed: 1956-04-24
Abstract: 825,855. Pistons. STERLING ALUMINUM PRODUCTS Inc. April 24, 1956, No. 12570/56. Class 122 (1). [Also in Group XXII] In an aluminium or magnesium-alloy piston having a cast-in protector ring for its packing ring receiving groove walls of a metal harder than the piston, the protector ring extends continuously circumferentially around and within the alloy body and has recesses extending circumferentially along and through the protector ring, and the recesses are sufficiently large to permit the molten aluminium to flow therethrough so that, upon solidification, the aluminium will shrink radially inwardly on the protector ring to anchor the ring in the piston body. The ring, Fig. 2, has recesses 11 and projections 12 by which it is supported in the mould 13, Fig. 20, during casting of the piston. Alternatively the ring may comprise two rings 10, spot-welded together and which, when the piston-ring groove is machined into the piston, Fig. 22, protects both walls of the groove. In another embodiment, Figs. 6 and 7, alternate displaced parts 20, 21 protect both sides of the groove. Various other forms of protector rings are shown. Specification 409,841 is referred to.

Title: Improvements in or relating to the manufacture of sliding clasp fasteners
IPC: A44B19/30
Filed: 1932-05-03
Abstract: 401,336. Sliding-clasp fastenings. CORNER, G. H. C., 507, Walsall Road, Perry Barr, and LIGHTNING FASTENERS, Ltd., Witton, both in Birmingham. May 3, 1932, No. 12706. [Class 44.] In a fastener of the type in which two flexible stringers each furnished with a series of interlocking elements are connected and disconnected by a slider mounted thereon and operable to open and close the fastener from the front or the back, the slider is fitted with a locking means which can be released by means of the operating tab from either the front or rear. With the arrangement shown in Fig. 1 the locking is effected by the engagement with the interlocking elements 9 of a detent 6 extending from a spring-pressed rocker 5 pivotally mounted on the front face 1 of the slider. The front tab 8 directly actuates the rocker 5 to withdraw the detent 6 while the rear tab 10 actuates a link 11 which passes through the slider and is connected to the rocker 5 on the other side of the pivot 4. Figs 3 and 5 show a construction in which a single tab 14 can be moved from the front to the rear of the slider by engaging a T-section member 13 mounted on and extending round the slider. This member 13 is of spring material and U-shaped with one end 18 pivotally mounted on the slider while the other end carries the detent 16, the outward movement of which is limited by a lip 17 bent up from the front face of the slider. The member 13 is retained between pressedup lugs 19, 20 on the two faces of the slider and rests on similar but lower lugs 22, 23. On pulling the tab 14 while within the limits e f the detent 16 is withdrawn by the flexure of the front limb of the member 13 but when the tab is at the rear and pulled while within the limits g h the rear limb is rocked about the pivot 18 and a pull is transmitted through the top connecting part of member 13 to the top of the front limb which is thus rocked about the fulcrum 22 and so withdraws the detent 16.

Title: Improvements in the recovery of hormones
IPC: A61K38/24
Filed: 1936-05-05
Abstract: Hormones are separated from crude aqueous liquids containing them, obtained from natural sources, by addition of a soluble ferro- or ferricyanide and a metal salt forming therewith an insoluble precipitate having adsorbent properties and then separating the hormone from the adsorbate by means of solvents. The liquids treated may be urine, serum, and extracts of the pituitary body, ovaries, corpora lutea, placentae or testicles. The soluble ferroor ferri-cyanides may be those of alkali metals, aluminium, barium or magnesium, and the metal salts may be cupric salts or zinc salts in the case of ferricyanides, and cobaltous, manganous and zinc salts in the case of ferrocyanides.  The suitability of any particular precipitate may be tested by ascertaining its power to absorb methylene blue form its solution.  The reaction is carried out at a pH value between 3 and 7, preferably at pH5.  According to examples a precipitate formed by reaction of zinc sulphate and potassium ferrocyanide is formed in (1) women's urine, the adsorbate being extracted with acetone to obtain oestrin and then with dilute ammonia to obtain gonadotropic hormone; (2) mares' urine, the adsorbate being extracted with acetone or alcohol to obtain oestrin; (3) mares' serum which has been pre-treated with picric acid to remove proteins; (4) an alkaline extract of anterior lobes of pituitary bodies which has been adjusted to pH 7,2 to separate a precipitate and then to pH 5,5 to cause precipitation of a mammae-stimulating hormone, the alkalisoluble anterior pituitary hormones being extracted from the adsorbate by dilute ammonia.
