Title: Improvements in and relating to the production of knitted hosiery and like fabrics
IPC: D02G1/02
Filed: 1955-02-03
Abstract: 804,938. Knitting. PATENTEX, Inc. Feb. 3, 1955 [May 10, 1954; Aug. 3, 1954; Sept. 2, 1954 (2)], No. 3271/55. Drawings to Specification. Class 74 (2). [Also in Group IX] Alternate courses, or alternating groups of courses, or a stretchable, retractable fabric are knitted from continuous filament thermoplastic synthetic polymer yarns to which have been imparted torsional stresses of opposite hand by heat treating the yarns and twisting, one in one direction and another in the opposite direction, the wildness so produced being temporarily restrained by plying each of the yarns with another yarn which can be subsequently removed by chemical action having no effect on the polymer yarns. A balanced, sheer fabric may thus be produced. The polymer yarns may be oppositely twisted, heat treated and again twisted (preferably reverse twisted beyond the starting point). The temporary restraining yarn may be silk or cellulose acetate and be removed by means of caustic soda acetone or acetic acid. The method may be used for ladies' stockings or underwear. A stocking made by this method has the usual sheer leg portion and reinforced areas. The reinforcing yarn may be the above yarn or conventional yarn. Specifications 566,507 and 786,551 are referred to.

Patent GB-700867-A (GB)
Title: Cation-exchanging resins
IPC: B01D15/04
Filed: 1951-02-14
Abstract: Cation exchange resins are made by condensing in acid medium an aromatic compound containing one or more etherified phenolic hydroxyl groups with an aldehyde, either the phenol ether, the aldehyde or both, containing at least one ion active group, continuing the condensation until a gel is formed and drying the gel at an elevated temperature.  Specified are:-cation exchange groups-sulphonic acid, carboxyl, sulphonamide, cyanamide and nitroalkyl; phenol ethers-anisole, diphenyl ether, diphenylene oxide, diphenylene dioxide, phenoxy ethane sulphonic acid and phenoxy acetic acid; aldehydes-formaldehyde, benzaldehyde, disulphonic acid and acetaldehyde disulphonic acid.  In examples:-(1) Anisole is heated with benzaldehyde - 2.4 - disulphonic acid to give a sulphonated triaryl methane derivative (see Group IV (b)).  The mixture is then heated with further anisole and formaldehyde.  (2), (3) and (4) Formaldehyde is condensed respectively with diphenyl ether sulphonic acid, phenoxy ethane sulphonic acid and phenoxy acetic acid (5) The sodium salt of benzaldehyde - 2.4 - disulphonic acid is introduced into an emulsion of diphenylene oxide and sulphuric acid.  After heating, sulphuric acid is added to the whole condensed with formaldehyde.ALSO:A sulphonated triaryl methane derivative of formula <FORM:0700867/IV (b)/1> is made by heating anisol with the sodium salt of benzaldehyde-2.4-disulphonic acid in sulphuric acid.  The derivative is heated with further anisol and with formaldehyde to make a cation-exchange resin (see Group IV (a)).

Abstract: 926,500. Respiratory appliances. B. F. GOODRICH CO. Feb. 1, 1962, No. 3905/62. Class 81 (2). A high-altitude flying helmet comprises an internal, apertured, flexible diaphragm 20, Fig. 1, which is sealed against the face and divides the helmet into two chambers, one of which 22 is supplied with oxygen through a demand valve 19 while the other is in communication with the interior of the suit 11 and can be pressurized as necessary. Gas from the regulator 19 passes through a tube 18 to a tube surrounding the face opening and having a series of orifices by means of which the gas is directed towards the transparent window 22. The flexible diaphragm 20, Fig. 3, is of impervious material and is attached to the helmet 10 around its outer edge while its inner edge is flexibly secured to a metal frame member 24. Attached to this is a sealing member comprising an air-impervious cushioning member 29, faced with an air permeable sponge layer 28, together with an impermeable sheet 26 attached to the front margin of the layer 28 and to the rear of the member 29. The enclosed space 30 is inflated with air received through a tube 35 and this causes the pad 28 to be pressed against the head and form an air-tight seal. At the same time, air from the space 30 percolates through the cushioning layer 28 and removes any perspiration which might accumulate from the prolonged contact with the skin. In a modified form of helmet the transparent portion is made as a pivoted visor which, when in the closed position, is also sealed by an inflatable, circular cushion.

Title: Improvements in and relating to miniature ranges for gunnery instruction
IPC: F41G3/28
Filed: 1927-02-11
Abstract: 288,767. Newton, P. I. Feb. 11, 1927. Teaching gunnery and ranging.-In a miniature range for gunnery instruction, means are provided for introducing a ratio of movement between the lines gun-target and sight-target, so that for any movement of the target towards or away from the gun there will be a change of tangent elevation which will have to be taken up by altering the range on the range dial. This is obtained by means of a pair of mirrors k, l. Fig. 10, one k above the line from the gun G to the target T, the other l below that line. The sighting is done by reflection from these mirrors, and the setting of these mirrors determines the aforesaid ratio of movement. The gun G and the mirrors k, l may be mounted on a circular base as shown in Figs. 5, 6; and a device p may be provided to change the pointing of the gun and to make the same gun simulate various guns of a battery. The target shown in Figs. 1, 2 comprises a wooden framework a covered with a layer of sand or sawdust b forming a concave sloping surface, over which one or more tanks d or other targets of rubber or wood are moved by means of cords e. A stop butt c is fitted behind the target and may be camouflaged with background and sky.
Patent GB-863730-A (GB)
Title: Metal composition having improved oxidation- and corrosion-resistance and magnetic characteristics, and method of preparing same
Inventor: JOSSO EMILE RENE ANDRE
IPC: C21D1/78
Filed: 1959-02-04
Abstract: An alloy having good oxidation and corrosion resistance, together with low magnetic remanence contains: Cr 12 to 40%, Mn 0 to 2%, C not more than 0.2%, Fe balance, and is produced by melting the constituents together, at least one stage between initial melting and the cooling of the solid alloy being carried out at subatmospheric pressure.  The furnace atmosphere is preferably non-oxidizing and nonnitriding.  By this means de-oxidation is effected without the necessity of adding separate de-oxidizing elements, the residues of which have a deleterious effect on magnetic remanence.  Any annealing necessary during working of the alloy is carried out within the range 600-1100 DEG C. in the substantial absence of air, and the magnetic properties are finally enhanced by annealing in the absence of air within the range 600 DEG -1300 DEG C, possibly followed by a second similar anneal within the range 550 DEG -950 DEG C, the temperature being at least 50 DEG C below the temperature of the first anneal. This heat treatment may be followed by a chemical pickling or similar treatment followed by a passivation treatment.
