Title: Fire retardant compositions comprising methyl methacrylate polymers
Inventor: JUKES ALAN WILLIAM
IPC: C08K5/521
Filed: 1963-09-16
Abstract: Fire retardant compositions comprise a homopolymer or copolymer of methyl methacrylate, said copolymer containing a major proportion by weight of polymerized methyl methacrylate, and from 3 to 25% by weight based on the weight of said homopolymer or copolymer of mono-(2-chloroethyl) phosphate and/or bis (2-chloroethyl) phosphate. Suitable co-monomers for the copolymer include acrylic acid, methacrylic acid, esters, particularly C1- 12 alkyl esters, of acrylic and methacrylic acid, styrene, substituted styrenes, e.g. halostyrenes, maleimide, N-substituted maleimides, e.g. N-aryl maleimides, acrylonitrile and mixtures thereof.  The polymers used can be prepared by known bulk or solution polymerization methods. Other ingredients may optionally be included in the compositions, e.g. dyestuffs, U.V. absorbers, heat stabilizers, plasticizers, substances which render the composition opalescent, e.g. polystyrene, and known fire-retardant agents.  In an example, fire-retardant polymethyl methacrylate sheets are prepared by adding a mixture of mono-(2-chloroethyl) phosphate and bis-(2-chloroethyl) phosphate together with azo-diisobutyronitrile to a partially polymerized methyl methacrylate syrup, and moulding the mixture at elevated temperature; comparison processes are also illustrated using mixtures of the corresponding ethyl, n-propyl, n-butyl and isopropyl acid phosphates instead of the chloroethyl acid phosphates.

Oct. 11, 1930, No. 30479. [Class 106 (i).] Two similar totalizers are arranged in axial alignment as a single unit and so that the values appearing on each are always complementary, one to the other. In the rear view given in Fig. 1, the complementarily numbered line counters 5a, 5b, Fig. 2, are simultaneously actuated by pinions 9, 10 fixed to the actuating-shaft 11. Alternatively the two counters may be identical in appearance and the actuating-pinion of one caused to rotate reversely to that of the other. In an example of work illustrated in Fig. 3c, the amount 1725À00 is entered in the column totalizer 23 and simultaneously in one line totalizer 5a and complementarily in the other 5b. The credit item 1690.50 is next entered in the column totalizer 24 and similarly in the line totalizers. To obtain the balance the larger item 1725.00 is now subtracted from both column totalizers and therefore subtracted twice from counter 5a and added twice to counter 5b giving the balance 34À50 on the latter.

Title: Foamed articles and production thereof
IPC: C09D5/25
Filed: 1963-09-17
Abstract: Foamed polyimide articles may be prepared by adding an anhydride of a lower fatty acid or an anhydride of an aromatic monobasic acid to a solution of a polyamide acid having recurring structural units of the formula <FORM:0999579/C3/1> wherein R is a tetravalent radical containing at least 2 carbon atoms, no more than 2 carbonyl groups being attached to any one carbon atom and R is a divalent radical containing at least 2 carbon atoms there being no more than 1 amino group attached to any one carbon atom, the polyamide acid having an inherent viscosity of at least 0.1, and then adding to the mixture formic acid, oxalic acid, trichloroacetic acid, malonic acid, citric acid or a -hydroxy butyric acid, agitating the mixture until gelation occurs to form a foamed polymeric composition having bubbles dispersed therein, shaping the composition into a cellular article and then heating the shaped cellular article.  The polyamide acid solution may be prepared by reacting at least one diamine with at least one tetracarboxylic dianhydride in the presence of a solvent. The preferred organic diamines are those of the general formula H2N-R1-NH2 wherein the R1 groups contain at least six carbon atoms characterized by benzenoid unsaturation.  Suitable dianhydrides are the aromatic tetracarboxylic acid anhydrides, particularly those wherein the four carbonyl groups of the dianhydride are each attached to separate carbon atoms in a benzene ring and wherein the carbon atoms of each pair of carbonyl groups is directly attached to adjacent carbon atoms in the benzene ring to provide a five-membered ring.  The preferred solvent is N,N-dimethylacetamide.  Suitable lower fatty acid anhydrides or aromatic monobasic acid anhydrides as dehydrating agents are acetic anhydride, ketene, benzoic, o-, m-, and p-toluic; m- and p-ethyl benzoic; anisic; and alpha and beta-naphthoic acid anhydrides. They may be used alone or in combination with a tertiary amine.  The conversion of polyamide-acid to polyimide takes place at the same time as foaming.  After shaping, the article may be dried at about 300 DEG  C. for 0.5 to 3 hours. Specification 999,578 is referred to.

Abstract: 926,186. Cooling dynamo-electric motors. GENERAL ELECTRIC CO. Oct. 30, 1959 [Nov. 3, 1958], No. 36893/59. Class 35. The stator end windings of an electric motor are cooled by copper strips 38, 40 (for bottom and top conductors respectively) taped to the windings and conducting the heat directly or indirectly to the stator core. These cooling strips may extend into the stator slots, or be secured to the outer frame, or (as shown) be secured by welding, wedging &c. to flat radial fingers 30 extending inwardly between the windings from a core-clamping ring 28. The stator is cooled by a supply of cooling water in the rotor bore which is sealed from the stator by an air-gap can (not shown). The radially inner edges of the cooling strips abut against a pressure-resisting ring (not shown) through which heat is conducted to the partition. The strips may be folded over the fingers 30, as shown in Fig. 4. If desired, an additional cooling tube 50 may be clamped at the other ends of the conducting strips. The effect of the conducting strips may be enhanced by thermally conducting tape or copper sprayed on to the end-turns. A shoulder 32 accommodates a ring (not shown) enclosing the end windings. The motor drives a hot-water pump.
