Title: Improvements in and relating to a process for reacting olefines with formaldehyde
IPC: C07D319/06
Filed: 1944-12-22
Abstract: Olefines are condensed with formaldehyde or a polymer thereof in the presence of an aqueous acid-reacting condensation catalyst under 75-2000 atmospheres pressure forming 1 : 3-alkane diols or 1 : 3-alkane-diol-cyclic or -linear formals.  The temperatures may be 30 DEG  C.-250 DEG  C. and preferably 100 DEG  C.-200 DEG C.  When some of the 1,3-alkane-diol-cyclic formals are added to the feed or when the molar ratio of water to formaldehyde is about 8 : 1, the diols are largely formed, but if the water/formaldehyde ratio is 1 : 1 the formals are mainly formed.  The preferred olefines are ethylene, propylene or butylene and the catalysts are, e.g hydrated boron fluoride, sulphuric acid, methyl formate, formic acid, acidic clay-like materials, phosphoric acid or calcium sulphate.  The reaction vessel is made or lined with an acid resisting material such as stainless or mild steel, copper, silver, nickel, enamel and glass and the process may be conducted continuously.  In examples: (1) a mixture of trioxymethylene, water, sulphuric acid and 1,3-butylene glycol cyclic formal is agitated at 165 DEG  C. under 600 to 700 atmospheres of propylene pressure.  The product is cooled, neutralized with aqueous calcium oxide, filtered and distilled to yield mainly 1,3-butylene glycol with some butylene glycol cyclic formal and isopropanol; (2) the same reactants as in (1) but with less water and without the addition of cyclic formal are agitated at 150 DEG  C. and 200 atmospheres propylene pressure.  The product is extracted with chloroform and yields 1,3-butylene glycol cyclic formal.  The aqueous layer is neutralized and on distillation yields mainly 1,3-butylene glycol linear formals and a little 1,3-butylene glycol; (3) the same reactants as in (2) but with more water are heated at 190 DEG  C. under 900 atmospheres ethylene pressure. Extraction with chloroform yields trimethylene glycol cyclic formal and the aqueous layer yields trimethylene glycol. According to the Provisional Specification any high pressure may be employed. Specifications 511,966 and 544,737 are referred to.

Title: Improvements relating to machinery for the decoration of pottery or other ware
Inventor: GOODSON FREDERICK JAMES
IPC: B28B11/00
Filed: 1950-10-24
Abstract: A machine for applying a line or band of decoration to pottery or other ware is characterized by the ware being centralized on a bench over a head which is then raised to lift the ware clear of the bench, the ware being held centralized by a plunger brought to bear on its upper surface coaxial with the head, the head having a rotary movement imparted to it.  A piece of ware P is placed on a bench 10, Fig. 1, over a head 22, keyed slidably to a shaft 21. This shaft is rotated by bevel gearing 20 with the aid of chain 17 and camshaft 15, which latter is in turn driven by a reduction gear 14 from a motor 11.  Below the head 22, the shaft 21 passes through a weighted sleeve 24 which is raised and lowered by a lever 25, which in turn is <PICT:0698341/III/1> <PICT:0698341/III/2> acted upon by a cam 28 on the camshaft 15.  When the sleeve 24 is lowered, links 40 connected to it move sliding jaws 41, mounted in guideways in the top of the bench, toward the axis of the shaft 21, and so centralize the ware P. The sleeve 24 is next raised, which withdraws the jaws 41 outwardly, and lifts the head 22, which in turn raises the ware P clear of the bench.  At the same time a cam 32, about a camshaft 31 driven from the camshaft 15 by a chain 29, acts on a lever 34, which lowers a spring-loaded plunger 37 so that the piece P is gripped between the head 22 and the plunger 37 and is rotated.  Decorating devices, as described in Specification 684,329, comprising a brush 126 fed with liquid through a hose, are carried by levers (one is shown at 45) actuated by cams 46, and are brought into contact with the ware. An edge lining brush, Fig. 6, contacts the edge of the ware when a cam on the shaft 31 operates a Bowden cable 160, Fig. 1, thereby lowering an arm 163 carrying the brush.  A spring-loaded roller 155, Fig. 6, carried by an arm 156, is maintained in contact with the edge of the article whilst the line is applied, and a guide pin 168, Fig. 6, rides on the top of the article so that a uniform band is applied round the whole periphery.  When the edge line is completed, cams tighten the cable 160, lifting the brush from the article, and push the guide roller 155 away.
