Title: Improved water closet
IPC: E03D11/10
Filed: 1943-11-03
Abstract: 601,812. Tipping-basin closets. PETER, F. A. Nov.. 3, 1943, No. 18243. [Class 26] Relates to sanitary closets of the kind comprising a chamber 5, Fig. 1, a pail 1 mounted over the chamber and open at the bottom, a basin 4 pivotally mounted inside the chamber which, in its normal position, surrounds the lower end of the pail and contains water to form a seal between pail and chamber, the basin being tilted downwardly by an operating lever 8a to discharge its contents into the. chamber against the action of counter-balancing means serving to return the basin to its normal position. A stop 14 is arranged in the path of the operating arm 8a to prevent the basin 4a, when tilted, from coming into contact with the back of the pail. A weight 16, Fig. 2, may be employed for counterbalancing the basin, a stop 17 being provided for arresting the weight, when the basin is returned to its normal position, so that the basin does not strike the lower edge of the pail. Instead of a weight, the counterbalancing may be effected by a spring 19, Fig. 3, acting on an arm 18 fixed on the pivot 15 of the basin. A stop 21 in the path of the arm prevents the basin, on returning to its normal position, from striking the lower edge of the pail. The spring 19, acting under tension, may be replaced by a spring acting under compression, as shown in Fig. 3. The operating lever 8a is held against accidental displacement in its normal position by a spring- pressed stop 11, past which it may be forcibly moved to tilt the basin.

Patent GB-459514-A (GB)
Title: Improved manufacture of sheets from polyvinyl chloride or the like
IPC: C08J5/18
Filed: 1935-07-08
Abstract: Sheets are obtained by a rolling operation from a mixture of a synthetic polymerizate of the vinyl group which by itself can be rolled only with difficulty, or not at all, and another polymerizate which is more easily rolled but by itself gives brittle sheets.  The two ingredients act as softening agents for each other.  The sheets obtained have high tensile strength, elongation, and electric insulating capacity.  They are of a high softening point. After-chlorinated polyvinyl chloride which of itself is practically incapable of being rolled may be mixed with polyvinyl chloride which by itself gives brittle sheets, and the mixture may readily be rolled with heating to form smooth coherent sheets.  In an example, after-chlorinated polyvinyl chloride and non-chlorinated polyvinyl chloride are mixed in equal proportions. The sheets obtained by rolling have a high softening point compared with those obtained from after-chlorinated polyvinyl chloride and a softening agent such as a phthalic ester. Similarly, the rolling of a mixed polymerizate from vinyl chloride and an acrylic acid derivative or styrene may be facilitated by mixing with polyvinyl chloride.

Title: Media for use in making camera copy and methods of preparing same
IPC: B44F5/00
Filed: 1945-07-30
Abstract: 606,569. Material for preparing drawings for photo-mechanical reproduction. SANDERS, L. S. July 30, 1946, No. 19506. [Class 98 (ii)] [Also in Group XV] Material for use in preparing drawings for photo-mechanical reproduction is made by printing on a base sheet of cellulose nitrate, cellulose acetate, ethyl cellulose or waterproofed paper, spaced parallel lines in which the lines are as wide as the spaces in between them, with white printing-ink or clear printing varnish; dusting the base with a chemicallydevelopable material such as lead sulphate in fine powder while the ink or varnish is still tacky; drying; sponging under a spray of water to remove unbonded developable material; drying; printing, with a similar printing plate to that first used, lines transversely or at right-angles to the lines first produced and with an ink containing another chemicallydevelopable material, such as mercurous chloride, which ink penetrates the dusted lines at the points of superimposition; drying, and again spraying with water to remove this ink from the places which it does not penetrate, to leave the base coated as shown in Fig. 3, in which alternate squares are coated with mercurous chloride, and with mercurous chloride, together with lead sulphate. The material may be given a surface coating, comprising starch and gelatin, to improve developer and ink-receptivity. The first developer may be aqueous thiourea, which produces colour in the mercurous chloride squares only as in Fig. 4, the second developer aqueous sodium sulphide, which makes both the mercurous chloride and lead sulphate visible, as in Fig. 5. In a modification, a gelatin coated paper sheet may first be printed with parallel lines of waterproof varnish or ink, dried, crossed with a line print of mercurous chloride ink which adheres to both the gelatin surface and the varnish, dried; immersed successively in aqueous lead acetate and sodium sulphate solutions to produce lead sulphate within the gelatin surface between the varnish lines; dried and treated with a solvent to remove the varnish and the superimposed mercurous chloride ink, to produce alternate squares of mercurous chloride and lead sulphate, of which the former may be developed alone to form a dot pattern as in Fig. 4, or both may be developed simultaneously to produce a result as in Fig. 5. In the modified method, other chemicals, also applied by double decomposition, such as cobaltous phosphate, nickelous phosphate, cupric tungstate, ferric phosphate or thalliumtungstate may be substituted for the lead sulphate, which substances will produce coloured precipitates with sodium sulphide. In either form of the invention a transparent base may be used. The material may be used in the production of plates for multicolour printing.
