Bedsteads convertible into seats.-In a seat of the type provided with a hinged back which can be positioned in line with the seat bottom to form a bed, the back is adjustable angularly and when in a horizontal position its lower edge is located close against the rear of the seat bottom. As shown, the back 4 is hinged at 5 to a plate 7 hinged at 8 to a plate 9 secured to the frame so that when the back is lowered the plate 7 may be on the plate 9 to bring the edges of the seat bottom and back close together. The back is supported in various position by a pair of hinged T-shaped arms 10<a>, one at each side, connected by a bar 15 and each having a notched arm 10 passing through the frame upright 2 and engaging pins 11. As shown in Fig. 3 the arms 10 and bar 15 support the outer end of the back when the latter is lowered. A front extension 16 is normally accommodated below the seat on frame members 17 and it carries at its rear end cranked pins 18 which, when the extension is pulled out, engage vertical guides 19 so that the end of the extension is raised to the level of the seat bottom. The upper end of the guides 19 are curved as shown and terminate in hook portion over which the pins 18 engage to support the inner end of the extension, the front end of which is, supported by hinged legs 20 having slots 23 engaged by stay members 24.

[Also in Division F2] Crank-case vapours are drawn through a tube 64, through an annular gap between an inturned flange 56 of a valve member 46 and a valve seat 72 formed at the end of a tube 70, and finally through an outlet 66 to the engine inlet manifold. The valve member 46 is carried by a diaphragm 34 which is secured to a cover 32 at its periphery and centre. Inner and outer folds 44, 42 in the diaphragm permit movement of the valve which is biased open by a spring 74. The inner fold 44 and the cylindrical extension 54 of the valve are so dimensioned relative to the valve seat that forces acting on them, as a result of manifold suction, are balanced so that the valve moves in response to pressure variations in only the crankcase breather pipe 64 and a connected annular space 62. The valve is closed by a bi-metallic spring 90 under cold starting conditions. A ball check valve 88 closes the outlet 66 in the event of an engine backfire. In a modification, Fig. 4 (not shown), the bi-metallic spring closes the check valve under cold conditions.

Title: Improvements relating to ethyl silicate
Inventor: DODGSON DOUGLAS PETER
IPC: C08G77/00
Filed: 1952-10-09
Abstract: A liquid ethyl silicate having an SiO2 content of above 53 per cent may be made (1) by esterifying silicon tetrachloride, or (2) treating an ethyl silicate of lower SiO2 content with aqueous ethyl alcohol, containing less than 11 per cent by weight of water, in amount sufficiently large for the water content thereof to effect the required degree of condensation of the silicate.  A hydrolysing agent such as hydrochloric acid may be used in the second method. Hydrochloric acid formed during the reaction, alcohol and, if desired, orthosilicate and/or volatile lower polymers thereof, are removed, for example, by air blowing or vacuum distillation.  In a modification, the amount of water introduced is less than is necessary to form a silicate of the required SiO2 content and part of the more volatile silicates are removed, e.g. by air blowing. Examples are given. The products may be used as binding agents in making refractories and refractory moulds from substances such as powdered calcined fireclay.

Title: Highly filled shaped polyamide articles and a method of making them
IPC: C08L77/00
Filed: 1959-07-22
Abstract: A mixture of finely divided high melting synthetic linear polyamide particles and finely divided particles of a solid inorganic nonlubricant filler, the latter constituting from 40%-75% by volume of the mixture, is cold pressed to form a shaped green article capable of being handled without distortion which is then fused by heating to a temperature above the melting point of the polyamide. The polyamide, e.g. polyhexamethylene adipamide, polyhexamethylene sebacamide, or polycaprolactam, is first precipitated from a solution by a precipitating agent, or is dissolved in a solvent which can dissolve the polyamide at elevated temperature but not at room temperature and is then precipitated as a fine powder by cooling the solution.  The powder should have an average ultimate particle size of less than 40 microns.  Suitable fillers include plaster of Paris, calcium carbonate, carbon black, zircon, cement and talc.  It is advantageous to add a small percentage of finely divided lubricant filler, e.g. polytetrafluoroethylene in an amount from 0,1%-2% by weight of the mixture of polyamide and non-lubricant filler. The polytetrafluoroethylene acts as a mould release additive and, in effecting a reduction in the coefficient of friction of the resulting piece, is of special advantage when forming bearings according to the invention.  The green article should be fused at a temperature not more than 50 DEG F. above the melting point of the polyamide.ALSO:A mixture of finely divided high melting synthetic linear polyamide particles and finely divided particles of a solid inorganic non-lubricant filler, the latter constituting from 40 to 75% by volume of the mixture, is cold pressed to form a shaped green article capable of being handled without distortion which is then fused by heating to a temperature above the melting point of the polyamide.
