Title: Condensation polymers from halomethylated aromatic ethers
IPC: C08J9/02
Filed: 1960-08-31
Abstract: Condensation polymers, which are usually foamed, are obtained by heating nuclearly halomethylated diaromatic ethers in the presence of catalytic amounts of ferrous phosphate, ferric phosphate or a mixture thereof.  In modifications there may be included in the reaction mixture (1) non-halomethylated diaryl ethers and (2) Friedel-Crafts catalysts.  Specified are halomethylated diaromatic ethers mixtures of chloromethyl or bromomethyl diphenyl oxides (and their methyl substituted homologues) containing more than one halomethyl group per aromatic ether molecule which mixtures may contain monochloro- or monobromo-diphenyloxide; and halomethylated phenyl biphenyl ether non-halomethylated diaryl ethers di-phenyl oxide and phenyl biphenyl ethers.  To obtain non-foamed products the reaction is carried out in the presence of a large amount of an acid acceptor, such as an oxide, hydroxide or carbonate of sodium, potassium or calcium; or in the presence of a solvent or plasticizer.  Fillers, e.g. fibrous glass, pelite-plaster agglomerate, exploded mica or magnesia may be incorporated.ALSO:Foamed condensation polymers are obtained by heating nuclearly halomethylated diaromatic ethers in the presence of catalytic amounts of ferrous phosphate, ferric phosphate or a mixture thereof.

Abstract: 918,147. Compressed gas containers. BERNZ CO. Inc., OTTO. Sept. 1, 1960 [Oct. 28, 1959], No. 30177/60. Class 8(2). [Also in Group XXIX] A combined dispensing and pressure relief valve for a liquefied gas container 7 comprises a dispensing passage formed by the housing and lateral passage 16 and axial passage 15 in a valve stem 14. A stem 14 carries a valve member 17 which co-operates with a valve seat 18. The valve seat 18 is secured to a sleeve 12 which passes freely through the cover 3 of the container and carries a relief valve closure member 11 which is urged by a spring 13 into contact with the cover to close the annular gap 25 between the stem 14 and the cover. The valve 17 is loaded by a spring 19. To dispense fluid, the stem 14 is depressed to open the valve 17. If at any time the pressure in the container rises above a predetermined value, this pressure acting on the bottom of valve member 17 lifts this member and the sleeve 12 against the spring loading 13, to open the valve 11 to relieve this excess pressure. In a modification, the relief valve is formed by a seal similar to 18 which normally seats on a shoulder of the valve housing and also acts as a seat for the valve 17.

Abstract: 494,798. Moving signs. SCHWEIGER, J. Nov. 5, 1937, No. 30432. Convention date, July 14, 1937. [Class 3 (i)] An advertising or display device comprises a closed liquid container consisting of two glass vessels a, b connected by tubes c, the whole framework a, b, c being pivoted at f and carrying by clips e a display panel d. A lamp k, located in a housing i topped by a funnel l, is disposed below the vessel b so as gradually to warm the liquid therein, which is under reduced pressure, and cause it to boil and condense in the cooler vessel a. The accumulation of liquid in the vessel a eventually causes the container and panel to turn through 180‹, after which the process is repeated by the heating of vessel a. Lenses directing sunlight on to the lower vessel may replace the lamp k. The vessels a, b may be cylindrical or spherical, and may be connected by a single straight tube and cause a display disc to turn in its own plane.

Title: Improvements in or relating to the manufacture of reinforced building units

Filed: 1956-10-12
Abstract: 830,381. Moulding reinforced concrete slabs. DUROX INTERNATIONAL S. A. Oct. 12, 1956 [Oct. 14, 1955; May 29, 1956], No. 31160/56. Class 87(2). Lightweight concrete building units are formed in a mould with reinforcement so positioned as to leave intermediate cross-sectional areas of the unit without reinforcement, allowing the building units to be easily subdivided by sawing. Longitudinal reinforcement rods, which may be joined by transverse rods welded to them, may be held between opposite walls of the mould by tension or may be untensioned and supported by transverse tensioned wires. To apply tension to a rod 8, Fig. 2, its end is clamped by chuck jaws 11 drawn into a sleeve 12 by a nut 9 and when both ends-of the rod are secured tension is applied by a nut 13, threaded on the sleeve 12, against the wall 14 of the mould. The ends of an untensioned reinforcement rod 15, Fig. 3, rest in sockets in holders 18 which pass through the mould walls. Wires 23, Fig. 4, are tensioned at right angles to the rods to support them from below, and may have beads 34 to assist location. A tensioning device at one end of the wire comprises a block 26, to which the end of the wire is secured, with a projecting stud co-operating with a nut 29, the block moving in guides 27 when the nut is tightened. Transverse wires may also be tensioned above the reinforcement rods to prevent the concrete from pushing them up as it expands in the mould. The wire may be tensioned by means independent of the mould walls e.g. weights. When the concrete has expanded and solidified the supporting wires are removed, leaving small harmless holes. The block may be exposed for cutting by turning down the walls of the mould, which are attached by hinges. The walls are raised again and the divided block conveyed in the mould to a curing chamber.
