Patent GB-985133-A (GB)
Title: Oxygenated polyene aldehydes
IPC: A23K1/16
Filed: 1961-03-22
Abstract: The invention comprises compounds of formula R-CH = CH-C(CH3) = CH-CH = CH-C(CH3) = CH-CHO wherein R is an alkoxy-substituted vinyl ring, e.g. one of <FORM:0985133/C2/1> R1 being C1- 18 alkyl.  When R has the first structure, the compounds are made by brominating the 3-position in the ionyl ring of Vitamin A aldehyde (with N-bromosuccinimide in presence of an alcohol R1OH) and reacting the brominated derivative with said alcohol.  When R has the second or third structures, the compounds are made by brominating the 4-position in the ionyl ring of alpha-ionone (using dibromoethylmethylhydantoin), reacting the brominated derivative with an alcohol R1OH to give R-CH = CHCOCH3, condensing the latter with a propargyl halide giving R-CH = CH -C(CH3)(OH)CH2-C ­ CH which is reacted with a 4,4-dialkoxy-2-butanone to give R-CH = CH-C(CH3)(OH)CH2-C ­ C-C(CH3). (OH)CH2-CH(O alkyl)2, the triple bond being partially reduced to a double bond, the product being finally dehydrated and hydrolysed to the polyene aldehyde.  The compounds of the invention may be converted to thiapyrans by reaction with H2S and subsequently to the corresponding carotenoids by desulphurization. Examples describe the preparation of compounds of the first formula in which R1 is n-dodecyl or methyl and a mixture of compounds of the second and third formulae in which R1 is methyl.  Specifications 742,865, 945,882 and 985,132 are referred to.

Title: Apparatus for marking superposed fabric layers
IPC: D06H1/00
Filed: 1948-04-16
Abstract: 649,829. Marking fabrics. EKHOLM, E. G. H. April 16, 1948, No. 10664. Convention date, April 19, 1947. [Class 100 (ii)] In apparatus for marking a pile of sheets with colour blown through an outlet hole in' a hollow needle, a double-acting colour pump operated in response to the movement of the needle through the pile delivers more colour during the upward than during the downward needle movement. The device shown is supported by a fixed arm 3 above a pile of fabric on a base-plate, and is operated by depression of a hand lever 9 connected to the arm 3 by a short link and to a movable collar 8 by pivots 11. A guide tube 6 is fixed against a shoulder 5 in an opening in the arm 3. An outer tube 7 which moves with the collar 8 is secured by a ring 13 to an inner powdered colour reservoir tube 14 having a filling pipe 16, cover 15 and a central ejector pipe 18 secured by a ring 17 so that its lower end is just above the mouth of the hollow needle 20 carried by an outlet nipple 19; the tube 7 also carries the cylinder 23 of a double-acting pump having air inlets 24, 25 with check-valves (not shown) and outlets 30, 35 with check-valves 29, 34, both these outlets being connected to the pipe 18. Between a strong spring 44 abutting the ring 13 and a weaker spring 45 abutting the shoulder 5 is a ring 43 secured to a tube 41 carrying an apertured abutting face 42 and connected by a rod 38 to the pump piston 26 whose leather &c. cup faces downwards. In operation the ring 43, abutting face 42 and piston 26 move downwards with the other moving parts until the abutting face is arrested by the pile of fabric, whereupon the needle 20 passes through the aperture therein and penetrates the fabric while the pump cylinder 23 moves down over the piston 26 causing slight compression of the air above the piston, sufficient merely to bring the colour to the needle point; during the upward stroke the strong spring 44 maintains the abutting face 42 against the fabric so that the cylinder 23 moves upwards over the piston 26 and the air compressed therebelow forces colour out of the needle outlet hole as it moves up through the pile of fabric. Specification 621,586 is referred to.

Wet -material is ground and dried in a two chamber tube mill wherein the first cham ber 2, Fig. 1, is charged at a ratio of 2:1 to 5:1 and preferably 3:1 to 4:1 of material to grinding elements. As described, material is fed via inlet 1 to chamber 2 until 20% to 30% of the chamber is. filled .with material and 5% to 10% with grinding balls. Drying gases supplied via conduit 6 leave via holes 7 and an extractor housing 8. Dried part reduced material leaves via a grid wall 9a and the housing 8.
