Title: Plug device for securing a fixing screw
IPC: F16B37/06
Filed: 1963-07-23
Abstract: 1,040,587. Fasteners. A. FISCHER. July 23, 1963 [Aug. 16, 1962 (2); Oct. 13, 1962; June 12, 1963], No. 29220/63. Heading F2H A synthetic plastics plug I, Figs. 1 and 4 (not shown), having an internally screwed portion 1b, is inserted through a plate 3, a screw 2 is inserted through a second plate 4, and screwed into the plug, thus deforming the latter at 1e and holding the plates together, portion 1d of the plug being ribbed on its outer periphery. Plates 3, 4 may be assembled flush with one another, or a part of portion 1d may be formed between the plates. In a modification, Figs. 6 and 8 (not shown), plug 11 co-operates with a plastics washer 8 to assemble plates 12, 13. The washer has external ribs 17 and an annular groove 8a so that when the washer is forced into the plug and screw 2 is tightened, bulging of the plug is produced at 11e, and edge 11g of the washer is forced into groove 8a, and engages the face of plate 12. In a modification of Fig. 6 (not shown), the screwed bore of the plug is blind. In a further modification, Figs. 12, 13 (not shown), plug 31 is tapered, and has ribs 31k. The bore of the plug is also tapered but at a greater angle than the plug exterior, thus providing a varying thickness.

Title: Improvements in gaseous fumigants
IPC: A01N59/04
Filed: 1951-12-13
Abstract: A gaseous fumigant contains one or more of the insecticides: hydrocyanic acid, ethylene oxide, methyl bromide, acrylonitrile, phosphine, trichloracetonitrile, chloropicrin, methyl formate, carbon disulphide, and liquid chlorinated hydrocarbons, in the gaseous or vaporized state, and one or more of the stimulants: nicotine, hexachlorocyclohexane, organic esters of phosphoric acid, organic esters of thiocyanic acid, organic amines, aldehydes other than formaldehyde, and ketones, in the vaporized state, the stimulant being present in the gaseous fumigant in a sublethal concentration. It is generally sufficient to employ the stimulant in a concentration of 10-5 to 10-9 grams per litre of fumigation space.  The concentration of stimulant preferably does not exceed saturation concentration in the gas phase at the temperature at which the gaseous fumigant is to be used.
Patent GB-777670-A (GB)
Title: Electric equalising networks
IPC: H04B3/14
Filed: 1955-10-14
Abstract: 777,670. Equalizing networks. STANDARD TELEPHONES & CABLES, Ltd. Oct. 14, 1955 [Oct. 21, 1954], No. 29340/55. Class 40 (8). The invention relates to equalization networks of the so-called " cosine " type such as are described in the Bell System Technical Journal, July 1953, commencing at p. 852. Such networks comprise a number of cascade-connected equalizing stages, the attenuation of which varies as the cosine of the frequency within a given range of frequency for a fundamental tone and its harmonics. Any attenuation function can be approximately produced within a given range by adjustment of the cosine amplitudes. According to the invention, the large number of identical phase-shifting networks normally required for equalizers of this type is reduced by designing the attenuating networks so that they form, with the phase-shifting networks, a reflecting junction at one end and a non-reflecting junction at the other end. As shown, the equalizing network, comprising alternate sections of phase-shifting and attenuating sections F and D, is connected to one pair of a set of conjugate terminals of a hybrid-network B, the other pair being connected to a balancing network N which may duplicate the series F, D. The other set of conjugate terminals constitute the input and output of the equalizer. The impedances, looking in either direction, of the attenuating sections are arranged so that reflection of the forward-going wave in a number of different phases takes place whereas no reflection of tho return waves occurs. The attenuating sections comprise T-networks of adjustable resistors which are so designed that the forward impedances may be adjusted to desired values whilst the backward impedances remain constant and equal to the image impedance of the phase-shifting sections. The attenuation of each section is designed to remain constant and independent of the adjustment. The Specification gives formulae for the resistors in terms of the desired attenuation and degree of mismatch.

Title: Improvements in or relating to absorbent bandages and the like
IPC: A61L15/26
Filed: 1960-08-25
Abstract: 960,427. Surgical dressings. KIMBERLY CLARK CORPORATION. Aug. 25, 1960 [Sept. 4, 1959], No. 29419/60. Heading A5R. A non-adherent dressing comprises a non- absorbent, non-woven, fluid-permeable web in contact with an absorbent element, the web comprising hydrophobic synthetic fibres united at their intersections by fused binder particles, the average smallest and largest dimensions of which are 10 microns or below and 100 microns or below, respectively, and the fusion temperature of the particles being lower than the melting point of the fibres. A surgical bandage or catamenial napkin comprises an absorbent filler 5 of creped cellulose sheets, short absorbent cellulose fibres ("fluff"), cotton or cellulose sponge. The non-woven wrapper 3 of non-absorbent bonded synthetic fibres covers all but one face of the filler, the thus exposed face of which may be covered with a layer 7 of gauze, scrim or a non- woven fabric of cotton and rayon or thermoplastic fibres. The wrapper consists of fibres derived from polyesters e.g. polyethylene terephthalate, polyamides, polyacrylates, polyvinyl chloride, polyethylene, polyacrylonitrile, tetrafluorethylene, or vinylidene chloride. The fibres are bonded by mechanical entanglement with synthetic binder particles which are later fused by heat treatment and which preferably have a similar chemical structure to the fibres used or with natural fibres. The synthetic binder particles consist of polyesters e.g. polyethylene terephthalate and copolymers of ethylene terephthalate and ethylene isophthalate, polyamides e.g. polyhexamethylene adipamides, polyethylene sebacamides and adipamides and their copolymers with caprolactam e.g. copolyamide of polyhexamethylene adipamide and polycaproamide, copolymers of acrylonitrile, polyacrylic and polymethacrylic esters, polyvinylchlorides and copolymers of vinyl chlorides with vinyl esters or vinylidene chloride, polyvinylidene chloride, polyhydrocarbons, chlorosulphonated polyethylene, polychlorotrifluoroethylene, polyvinyl alcohol, partially hydrolized vinyl polyesters, polyurethanes, polyureas, polythiolesters, polysulphonamides, polysulphones, or polyoxymethylene. 100 parts of synthetic fibre may be bonded with from 1 part to 45 parts of binder particles. The web is formed by a paper-making technique. Specification 868,651 is referred to.

The vessel is designed to supply metal to a continuous type chill mould, metal being caused to flow out through spout 22 and snout assembly 70 by pressure of argon or other inert gas applied to the top of the reservoir through pipe 104. The gas valve may be controlled automatically by a sensor to keep the rate of flow constant. The reservoir is repeatedly filled from ladles through spout 20 which is lined with a pre-fired sleeve (Fig. 3, not shown) and is fitted at the top with a removable burner assembly 50.
