Title: Method of producing a durable mechanical bond between glass and another material
IPC: C03C27/04
Filed: 1956-11-14
Abstract: For bonding glass to another solid material, titanium dioxide is incorporated with a thermosetting synthetic resin and a hardener therefore and the content of materials volatile up to 100 DEG C. is reduced to less than 0,1% by wt, the bonding composition is introduced between the glass and other material and hardened by infra-red radiation at a temperature not exceeding 150 DEG C.  The quality of TiO2 used is such that the coefficient of expansion of the composition approximates that of the glass, e.g. 15-30% by wt. of the composition.  The bonding mixture is of an epoxy resin or a phenol-formaldehyde resin and a polyamide, "Thiokol" Registered Trade Mark or neoprene.  When an epoxy resin is used with a polyamide modifier the latter also acts as a hardener, but when it is used with Thiokol or neoprene, a hardener such as a polyamide or a conventional acid hardener must p  be added as well as the modifier.  A suitable bonding composition which may be used for a multi-pane window assembly (see Group X) contains 40% epoxy resin, 30% polyamide and 30% TiO2.

Abstract: 2 - Methyl - 4 - (p - tert - butyl - phenyl)-but-1-ene is prepared by the action of methallyl chloride, bromide or iodide on p-tert-butyl benzyl sodium.  Sulphuric acid treatment then gives 6-t-butyl-1,1-dimethyl indane.ALSO:The invention comprises compounds of formula <FORM:1036286/C2/1> where M is an alkali metal.  They may be prepared by the reaction of the appropriate phenyl metal on p-tert.-butyl toluene.  The phenyl metal may be prepared in situ by reaction with a halobenzene.  Phenyl sodium or phenyl potassium may be prepared in an inert solvent such as aliphatic or aromatic hydrocarbons free of halogens and halide hydrogen atoms, which would react with the alkali metal.  Preferably, the solvent should not boil below the reaction temperature under standard pressure, but solvents such as benzene may be utilized under pressure.  Other solvents are n-octane and isooctane. It is most convenient to employ p-tert.-butyl toluene as solvent and the metal should have a large surface area. The halobenzene may be added to a mixture of p-tert.-butyl benzene and the metal at 30-40 DEG  C.  Chlorobenzene, bromobenzene or iodobenzene may be used. The metal may be in up to 5% excess.  To complete the reaction the mixture is heated at 90-120 DEG  C. for 4-8 hours.

Title: A new method of rock blasting and devices for the purpose
Inventor: MCAUSLAN JAMES HAY LOUDON
IPC: F42B3/16
Filed: 1960-10-17
Abstract: 919,737. Detonating devices for blasting; explosive and pyrotechnic compositions, IMPERIAL CHEMICAL INDUSTRIES Ltd. Sept. 27, 1961 [Oct. 17, 1960], No. 35462/60. Classes 9 (1) and 9 (2). A detonation initiating device for rock blasting comprises a tubular casing with a watertight closure at both ends, but permitting at one end the insertion of igniter cord which engages a charge 17 of incendiary composition located at that end of the tube. The other end contains the initiating explosive charges of an ordinary detonator, and in an intermediate position is a delay element comprising a charge of slow burning composition 15, which has a burning speed of not more than 10 cm. per minute. Ignition of the charge of incendiary composition by the igniter cord causes ignition of the slowburning composition which, after burning along its length, causes the ignition of the initiating explosive charge and the consequent detonation of the blasting explosive charge adjacent thereto. The igniter cord connects a series of these detonating devices and thus there is a series of explosions, the first of which occurs after the flame of the igniter cord has reached the last detonating device owing to the delay between the flame reaching the device and the actual explosion, produced by the slow burning composition. In one form of the invention the tubular casing consists of two parts; the detonator casing 11 and the connector casing 12 which is constructed to be a sliding fit within 11. A base charge 13 is pressed against the closed end of 11 and charge 14 of initiating explosive is pressed against the base charge. The delay element 15 is located between 14 and a primary charge 16. The connector casing contains at its closed end the charge of incendiary composition 17 slotted at 20 to permit entry of the igniter cord. The casings are crimped together at 19. The casings may be sealed together by means of a waterproof seal or a layer of waterproof sealing may be placed between the overlapping parts of the casing. The delay element may be made of lead and the slow-burning composition of cobalt dinitro bis-ethylenediamine nitrite or a mixture of 65 parts potassium nitrate, 10 parts sulphur and 2 parts of the condensation product of naphthylamine and acetaldehyde prepared as described in Specification 576,107. The incendiary composition may comprise a mixture of red lead, potassium perchlorate, potassium nitrate, silicon, calcium silicide and iron powder, bound together by a composition consisting of nitrocellulose, dibutylphthalate, diphenylamine and citric acid.
