Title: Improvements in coloured textile materials
Inventor: OLPIN HENRY CHARLES
IPC: D06P1/653
Filed: 1951-01-18
Abstract: Dyeings on cellulose ester or ether fibres have their resistance to combustion products of coal gas improved by the incorporation in the material of an alkali metal phthalate.  The process is especially applicable to cellulose acetate dyed with aminoanthraquinone derivatives, alone or mixed with cellulose fibres dyed with direct colours, or with other fibres such as silk or wool.  The amount of phthalate used may be 0.5-2 per cent by p  weight of the material. It is applied from aqueous solution by impregnation, e.g. padding. Examples show the application of 1 per cent of disodium phthalate to (1) a cellulose acetate fabric dyed with the blue product of reaction of leuco-quinigarin with a mixture of methylamine and ethanolamine; (2) a cellulose acetate/cotton mixed fabric dyed green with a mixture of 1-methylamino-2-phenylaminoanthraquinone, 2 - nitro - 4 - chloro - 4\sv - methoxydiphenylamine, Chlorantine Fast Blue GLL and Chlorantine Fast Yellow 2RLL.  According to the Provisional Specification alkali metal citrates may be used in place of phthalates.

Title: Improvements in or relating to gas masks
IPC: A62B18/00
Filed: 1924-01-18
Abstract: 222,366. Davis, R. W.G. Jan. 18, 1924. Respirators.-In a gas mask of the type comprising an inner ori-nasal mask and an outer facial mask, the exhaled air is discharged directly from the inner mask to the exterior, and the inspired air is drawn into the space between the masks in such a way as to impinge upon, or flow adjacent to, the eye-pieces; by this arrangement the clouding of the eye-pieces is prevented. As shown in Fig. 1, air exhaled from the inner mask a passes directly to the exterior by way of a tube m and non-return valve l. The inspired air is drawn through a tube j and orifices n into the space h between the inner mask a and the outer mask b, and is then drawn through the orifices k<1> into the interior of the inner mask. The orifices k<1> may be partly covered by shields o, as shown in Fig. 3, to force the incoming air to flow in the desired direction. In a modified construction, the incoming air is made to impinge on the eye-pieces by tubes leading from the orifices n, and the orifices k<1> are provided with non-return valves.

Title: Process for the manufacture of sand and zircon cores and moulds for foundry purposes
IPC: B22C1/20
Filed: 1955-01-19
Abstract: In the manufacture of sand or zircon cores and moulds for foundry purposes using as a binding agent a drying or semi-drying oil, such as fish, linseed, oiticica, or boleko oil, paraffin or paraffin oil, or a natural resin, such as tall oil resin, an oxidizing chlorinated product is added to the sand or zircon just before use.  The oxidizing chlorinated product may be bleaching powder but is preferably sodium chlorite, which is added to the sand or zircon in quantities of 0.5-15 per cent by weight of the binding agent.  The oils may have previously been treated with drying agents, or by blowing or heating, and with the sand or zircon may also be incorporated dried sulphite liquor, vegetable or animal tars, additional resin, starch or dextrin, and also small quantities of water.

This arrangement causes air to be sucked into the regions adjacent the trailing faces of the steps to reduce skin friction and to prevent this air from mixing with the water stream entering the propeller a longitudinal rib 13, 14 or a channel 15 (as shown in left hand half of Fig. 11) or both (as shown in right hand half of Fig. 11) may be located on either side of the keel (see also Figs. 9 and 10, not shown). Alternatively but for the same reason, the inner end of each strip may taper and extend aft in a direction parallel to the keel (Figs. 7-10, not shown). If the craft has twin propellers, the ribs 13, 14 and channels 15 are replaced by two wedge shaped recesses terminating at the transom edge of the bottom (Fig. 13, not shown).

Title: Alkylsilsesquioxanes
IPC: C08G77/04
Filed: 1949-01-27
Abstract: Soluble, completely condensed alkylsilsesquioxanes, having the formula (R.SiO1,5)n, where R is an alkyl radical containing 2 to 6 carbon atoms and n is an integer from 8 to 24, are made by destructive distillation of an alkylsilsesquioxane hydrolysate (i.e. the hydrolysis product of a silane having the formula R.SiX3, where R is an alkyl radical containing 2 to 6 carbon atoms and X is a readily hydrolysable group such as alkoxy or halogen atom), or by distillation above 200 DEG  C., but preferably below 500 DEG  C., and at a pressure below 5 mm. of a mixture of an alkali metal hydroxide and either the hydrolysis product of an alkyltrichlorosilane or an incompletely condensed alkylsilsesquioxane polymer, in which the alkyl radical contains 2 to 6 carbon atoms.  The products may be separated into their components by fractional distillation or by crystallization.  In examples: (1) C3H5SiC13; (2) C2H7SiC13 and (3) n-C4H9SiC13 were hydrolysed and the resulting oily-products mixed with powdered NaOH and distilled under reduced pressure to give paste-like products from which were separated by crystallization from acetone (C3H7SiO1,5)8, (C2H5SiO1,5)8 and (C4H9SiO1,5)8, respectively, the p  uncrystallized material remaining in each case being a viscous oil; (4) distillation of NaOH and the hydrolysis product of C6H13SiC13 gave a mixture of polymers containing an average of 14.8 units of the formula (C6H13SiO1,5).  The liquid compounds may be employed as lubricants and damping fluids.  When heated to above 150 DEG  C. with or without catalysts such as alkali metal hydroxide or alcoholate and organo metallic salts such as lead naphthenate, they form insoluble resinous compounds, and consequently find use in coatings, adhesives and potting compounds.

An aircraft is braked by a parachute streamed from its tail and having rigging lines 122 leading from the periphery of the canopy 12 to a winch 14 and a rigging line 123 leading from the apex of the canopy to a winch 15. The parachute is deployed during the approach phase with its canopy fully inverted (Fig. 1, not shown), by a pilot parachute 13. The lines 123 are wound in for the final approach to increase the drag (Fig. 4, not shown) and on touchdown the line 123 is paidout so that the canopy is fully deployed. During the last part of the ground run the lines 122 to the periphery are paid out to invert the canopy and then both winches are driven together to wind in the lines 122, 123 to prevent the canopy contacting the ground.
