Patent FR-1290541-A (FR)
IPC: B29C43/00
Filed: 1961-05-16
Granted: 1962-04-13
Abstract: A golf ball half shell is moulded (see Division B5) from a polyurethene pre-polymer, that is the starting material prior to curing.  The prepolymers are prepared by reacting an organic polymer containing hydroxyl groups with an organic polyisocyanate or polyisothiocyanate. Examples of such organic polymers include polyesters, polyethers and polyesteramides, all of which must, however, contain residual isocyanate-reactive groups.  Examples of suitable polyesters include polyethylene glycol adipate, polyethylene glycol sebacate, polypropylene glycol adipate and also copolyesters. Examples of suitable polyethers include polyglycols from propylene oxide and tetrahydrofuran. Polyisocyanates which may be used include naphthalene diisocyanates, tolylene diisocianates and diphenyl methane diisocyanates.  Poly-urethane pre-polymers which may be used include Registered Trade Mark "Adiprene" L.167, which is prepared from polytetrahydrofuran and tolylene diisocyanate. Curing is effected by means of cross-linking agents e.g. a substance containing at least two active hydrogen atoms per molecule such as diols and diamines.  The polyurethane pre-polymer/cross linking agent mixture may be admixed with mineral oils, fillers and colouring materials. In the example of the process given titanium dioxide (anatase) was dried at 140 DEG C. for 1 hour.  On cooling to room temperature in a closed container the titanium dioxide was mixed with twice its weight of methylene bis (orthochloranilene) (MOCA), as a cross-linking agent, and the mixture milled for 24 hours.  The mixture was then heated in an evacuated vessel to 140 DEG C. to remove dissolved gases, the mixture being subsequently stored in an oven at 110 DEG C. in a sealed container.  30 parts of the mixture at 110 DEG C. were stirred with 100 parts of Adiprene L.167.  After moulding of the ensuing mixture, the mixture was cured for 10 minutes between platen heated to 105 DEG C. and 100 DEG C. under pressure, the mould then being brought to room temperature in about 7 minutes.  The mould was then transferred to an insulated box containing solid carbon dioxide, the mixture being taken from the mould when its temperature had fallen to about -12 DEG C. and stored in a metal container surrounded by solid carbon dioxide. The mixture was finally cured between platen at 100 DEG C. for 15 minutes under pressure, the mixture being then cooled to room temperature again in about 7 minutes.  The final curing time was varied, a resulting property being given in the Specification in tabulated form.

Abstract: O-xylene and/or naphthalene are oxidized to phthalic anhydride in the presence of air at 350-440 DEG  C. using a catalyst comprising an oxide of a metal selected from Groups IV to VIII on a support which is prepared by coating the support with the metal salt at 90-200 DEG C for 1/2 -8 hours until the support is dry to touch and completing the drying by heating at 200-450 DEG  C. in less than 90 minutes, the drying being commenced within 3 hours of the end of coating.  Less than 1.5% of naphthaquinone is produced using a single pass reactor. An example describes the oxidation of naphthalene using V2O5 on SiC at 415 DEG  C.ALSO:Oxidation catalysts are made by contacting one part of a Group IV - VII metal oxide as the corresponding metal salt solution with 5 to 20 parts of a support having a surface area of less than 1m2/gm., less than 5% of binder and a heat conductivity of at least 1.80 BTU/hr.sq.ft. DEG F/ft., coating the support with the metal salt at 90 - 200 DEG C for 1/2 to 8 hours and drying by heating from 200 to 450 DEG C in less than 90 minutes the final drying step being commenced within 3 hours of the end of the coating step.

Abstract: 538,306. Composite boards. HITCHINS, W. G. Jan. 17, 1940, No. 1014. Drawings to Specification. [Class 145 (ii)] A composite board for internal walls and ceilings of buildings consists of two facing members maintained in spaced relationship by pieces of veneer on edge in the form of separate cylinders or other geometrical shapes packed closely together. The shapes are formed by bending round a strip of veneer of the desired width and securing its ends together by glueing,. stitching or tacking. The most suitable material for them is single wood veneer with the grain running perpendicularly to the face of the block,. or three-ply with the grain of two of the three plies running in such direction. Straight or wavy runs of veneer on edge may be used between the shaped separators. The board is made by arranging a glued wooden frame on one of the facing boards, packing the glued spacing members in position and superimposing the other facing board. If the facing boards are plaster boards a fibre strip is first secured to the frame and the plaster board secured by adhesive to the fibre. Specification 477.032, [Group X], is referred to.
