Title: Phosphorus-Containing Polyols and Polyurethanes Prepared therefrom
IPC: C08G18/50
Filed: 1967-01-26
Abstract: 1,165,994. Polyol phosphonate esters. UPJOHN CO. 26 Jan., 1967 [2 March, 1966], No. 4017/67. Heading C2C. [Also in Division C3] The invention comprises a polyol-phosphonate ester having the formula wherein R represents from 0 to 3 substituents selected from lower alkyl, lower alkoxy or lower haloalkyl radical having 1 to 6 carbon atoms or halogen, A is an alkylene radical having 2 carbon atoms separating the indicated valencies and having a total carbon atom content of 2 to 8 inclusive, n is 1 or 2 and x has a value of 1 to 3 inclusive. They can be prepared (a) by reacting a a phosphoric acid of the Formula II with the appropriate alkylene oxide or mixture of alkylene oxides preferably in the presence of an inert organic solvent, e.g. benzene, chloroform, carbon tetrachloride, or tetrachlorethane or (b) by esterifying the free acid II with a glycol HO-(A-O) x H if desired in the presence of a solvent, or (c) by an ester interchange process effected by heating a di(lower alkyl)ester of the acid II and the glycol HO-(A-O) x H, if desired in the presence of an inert solvent. A combination of the three methods may also be used, e.g. esterification of the acid (II) or lower alkyl ester thereof with the glycol to form a product in which x is 1 and then reaction of this product with an alkylene oxide in the presence of an alkaline catalyst. When it is desired to carry out method (a) to yield compounds in which x is greater than 1 it is preferable to use a catalyst, e.g. a tertiary amine or an alkali metal hydroxide or alkoxide, the products in this case having predominantly secondary terminal OH groups. The products are useful for incorporation in polyisocyanate - polyol reaction mixtures for the production of fire-retardant polyurethanes. Diethyl p-chloromethyl benzyl phosphonate is obtained by reacting p. xylyl dichloride with triethyl phosphite under reflux at 120-122‹ C.

Title: Improvements in or relating to explosive projectiles (such as bombs or aerial torpedoes), and electrical apparatus for controlling their movement during flight
IPC: F41G7/24
Filed: 1939-02-09
Abstract: 524,876. Electric control systems. SPERRY GYROSCOPE CO., Inc. Feb. 9, 1939, No. 4308. Convention date, Feb. 15, 1938. [Class 40 (i)] [Also in Groups XXXV and XL] In a system for controlling the flight of a bomb after its release from an aircraft so that the bomb may be caused to hit the target, the bomb-sight controls a directional radio transmitter of ultra short waves and the bomb is provided with a radio receiver which maintains the bomb on the radio beam through the intermediary of servomotor mechanism. Fig. 4 shows the transmitting antennae 3 which are located at the focus of a reflector 4 carried by a universally mounted telescope 5. The bomb carries two dipole antennae 8, 8<SP>1</SP>, Figs. 2 and 3, arranged at right angles on a reflector 9, the antenna 8 being connected to a coil 10 inductively coupled to a coil 11 connected to rectifiers 12, 12<SP>1</SP> the plate currents of which control the position of a valve 19 by means of solenoids 17, 17'. The valve controls the output of compressed air from a tank 20<SP>1</SP> through one or other of the pipes 22, 22<SP>1</SP> which extend radially in opposite directions through the housing of the bomb. The antenna 8<SP>1</SP> operates similar servomotor apparatus for controlling the outlet of air from pipes arranged at right angles to the pipes 22, 22<SP>1</SP>. Upon releasing the bomb the operator focusses the telescope on the bomb during its flight and when the target moves into the field of vision the radio transmitter is switched on and the central line of the sight moved gradually towards the target. This motion of the sight causes the radio receiver on the bomb to operate the servomotor mechanism and cause blasts of air to alter the course of the bomb ; furthermore the control-system is such that the bomb is automatically maintained on the beam. The bomb may carry a lamp to facilitate sighting. In a modification instead of using the reaction forces of the air blasts, movable fins provided on the bomb are controlled by the pneumatic or hydraulic servomotors through cables. A circuit 24 of the type desscribed in Specification 480,115 or U.S.A. Specification 2,068,490 and responsive to rate of change may be included in the output circuit of the valves 12, 12<SP>1</SP>.

Title: Measuring tapes
IPC: G01B3/10
Filed: 1943-03-18
Abstract: 579,054. Measuring tapes. TRIGGS, W. W. (Lufkin Rule Co.). March 18, 1943, No. 4434. [Class 106 (ii)] A measuring tape made of flexible ribbon metal is formed with a pitted or matt-like surface, portions of the surface having a coating to form markings and graduations and a contracting coating of rust-resistant metal abutting said first-mentioned portions to constitute a back-ground and provide a glare free and light-diffusing surface. In the manufacturing process the metallic ribbon 1, Figs. 4 and 10, is subjected to a treatment that gives, at least, one of its surfaces a pitted or matt-like appearance 2 as by sand blasting, etching or spraying metal. Conventional markings 3 are then applied by using ink or equivalent substance and hardened. The background portions 4 are then electroplated by depositing nickel, or silver. An additional electroplating step may be given, using chromium or other hard metal 6. to produce a durable surface. A transparent lacquer may then be applied. Rust-proofing treatment may be given before the step of marking and electroplating by immersing the metallic ribbon in a heated solution that leaves a phosphate coating on the surface. Scrubbing the surface with water or dilute muriatic acid' prepares the surface for the further treatment. Alternatively the pitted area may be limited to the marking and graduations or to the background only. The pitted area has a coating of metal thereon while the unpitted area has a coloured surface by the application of ink, paint or like colouring material after being rendered absorbent by a rust-proofing reaction or by the application of a resist that is bonded to the surface.

Title: Improvements in or relating to the reduction of the viscosity of confection compositions and viscosity reducing agents therefore
IPC: A23G9/32
Filed: 1939-02-13
Abstract: 528,377. Compositions containing wetting agents. AMERICAN LECITHIN CO. Feb. 13, 1939, Nos. 4666 and 4667. Convention dates, Oct. 13, 1938 and Oct. 17, 1938. [Class 15 (ii)] The viscosity of confection compositions of the kind containing comminuted material dispersed in fatty material is reduced by the addition of a salt of a carboxylic acid containing as the negative lipophillic portion an aliphatic residue having more than six carbon atoms. The salt, which is stated to have colloidal, wetting, and dispersive properties may be dispersed in a solvent which mixes with the fatty material before it is added to the confection or it may be formed in situ in the solvent, which may be an oil, fat, wax or fatty acid. For example, aluminium ethylate may be added to cocoa butter which is subsequently used in the manufacture of chocolate, when the aluminium salts of cocobutter fatty acids are produced. In examples : (1) soya fatty acids are partly saponified by heating with calcium hydroxide. The mixture may be used to improve the emulsification of coconut oil and sugar in the manufacture of caramels or to reduce the viscosity of chocolate ; (2) corn fatty acids are partly saponified with magnesium oxide ; the product may be used in chocolate or toffee: (3) soya fatty acids are partly saponified by heating with alcoholic potash; the product may be used in chocolate or caramels : (4) aluminium oleate, prepared from oleic acid by neutralizing with caustic soda and heating with ammonium alum is mixed with cocoa butter or cocoanut oil and used in chocolate or caramel. By adding the salt and lecithin in a fatty carrier to chocolate, blooming is avoided, even when water is present as in coated ice cream. Iron, boron, aluminium, bismuthyl, monoethanol amine and caffeine salts of fatty acids are specified and residues of the following acids, oils and waxes are mentioned : caproic, capric, abietic, hydroxystearic, lauric, melissic, myristic and ricinoleic acid, lard, corn oil, soya oil, teaseed oil, beeswax, carnauba wax and Japan wax.
