Title: A process for the manufacture of unsaturated alcohols and acyl derivatives thereof
IPC: C07C33/02
Filed: 1960-02-16
Abstract: Unsaturated alcohols and their acyl derivatives of formula A-CH=CH-CH=CH-B, in which A and B are straight chain alkyl groups together containing 10-14 carbon atoms, one of them having a terminal hydroxy or esterified hydroxy group as substituent, are produced by reacting an aldehyde of formula <FORM:0874581/IV (b)/1> in an inert solvent with a phosphorane of general formula:  <FORM:0874581/IV (b)/2> which A1 and B1 represent alkyl groups together containing 9-13 carbon atoms of which one radical contains a terminal carboxyl or esterfied carboxyl group or a hydroxy-methyl or esterified hydroxy-methyl group or an acetal group, one of the symbols m and n is 1 and the other 0, and in which the bonds denoted by broken lines indicate that the triple bonds may be replaced by double bonds; and, in any desired sequence, catalytically partially hydrogenating catalytically the triple bond (if any) to a double bond and transforming the terminal substituent in a manner known per se into a hydroxy-methyl or esterified hydroxy-methyl group where necessary. The condensation of the phosphorane with the aldehyde is suitably carried out in ether, methylene chloride or a hydrocarbon at a temperature between 0 DEG C. and the boiling-point of the solvent preferably in an atmosphere of nitrogen.  The partial hydrogenation of any triple bond may be carried out using a lead-inhibited palladium catalyst.  The phosphoranes used as starting materials may be obtained by reacting the corresponding phosphonium halides with lithium phenyl, lithium butyl, sodium methylate or aqueous sodium hydroxide; the phosphonium halides themselves may be obtained from the corresponding halides by reacting them with triphenyl phosphine. In the example 6-bromo-hexanol-(1) (prepared by treating hexamethylene glycol with cuprous bromide and HBr) is added to triphenyl-phosphine in benzene to give (6-hydroxy-hexyl)-triphenyl phosphophonium bromide which is treated with lithium phenyl to give the corresponding phosphorane; nonen-(2)-al-(1) is added to the phosphorane to give pentadecadiene-(6.8)-ol-(1).

Filed: 1955-03-07
Abstract: 789,125. Knitting-machines. MELLOR BROMLEY & CO., Ltd. Feb. 29, 1956 [March 7, 1955; June 2, 1955], Nos. 6612/55 and 15842/55. Class 74 (2). Mechanism for effecting adjustment of the stitch cams or the movable instruments of a circular machine comprises a number of rings concentric with the needle cylinder through which, either mechanically or electrically, selection is made from a radial bank of pins to effect the adjustment. As applied to a rotary cylinder- and-dial machine the radial bank of pins 30 is carried in an annular carrier 2 above the dial and is rotated synchronously with the dial and cylinder. The rings 10 form electrical conductors mounted in a stationary annular support 9 above the carrier 2 and are contacted by carbon brushes 19 coupled to solenoids 1 one of which is mounted above each pin 30 to effect its actuation. The rings are coupled electrically to micro-switches 12 operated by feelers 20 at the dictates of a pattern drum 38 such that operation of a switch 12 causes the associated solenoid to project its pin 30 which as it rotates with the carrier 2 then strikes a star wheel 15 coupled to a stitch cam to adjust the position of the cam. Instead of the rings being electrical conductors they may be coupled by flexible cables to the feelers and be rotatable within their support 9. In this case the rings carry studs which project downwardly and engage levers which project the pins as they rotate. Movement of the rings causes the pins to project at a time when they are passing the star wheels and thereby engage the wheels to adjust the cams.

Abstract: 1479993 Pressure gauges DAHLTRON CORP 17 Feb 1975 [22 Feb 1974] 6685/75 Heading G1L [Also in Division F1] A double-acting hand pump, especially for inflating tyres, comprises a piston 42 dividing a cylinder 22 into working chambers 44, 46 a hollow piston-rod 48 through which air pumped from the working chambers 44, 46 is delivered, and a permanent restricted passage 106 inter-connecting one of the working chambers to the piston-rod interior whereby, on releasing the cylinder 22 from a position in which the one working chamber is a minimum, air flows through the passage 106 and expands the one working chamber by an amount proportional to the inflation pressure. In the embodiment shown the restricted passage 106 leads to the chamber 46 and is constituted by the clearance between the engaging screw threads 102, 104 on the piston and piston-rod, respectively. As the chamber 46 expands it compresses air trapped in the other chamber 44 until equilibrium is reached. By constructing the cylinder 22 or a portion thereof of clear plastics the equilibrium position of the piston can be read off on a calibrated pressure scale 40 on the cylinder 22. Opposite end of the cylinder 22 are closed by perforated end closures 26, 30 mounting annular valve members 72, 88, the latter comprising lips 78, 94 which flex inwardly to allow the entry of air to the cylinder when the adjacent working chamber is expanding. Air compressed in the contracting working chamber enters the piston-rod through an annular groove 110 and passages 112 in the piston 42, the groove 110 containing a piston ring 114, 118 provided with lips 116a, 116b which co-operate with the sides of the groove 110 to form non-return delivery valves. A hose 58 is stored within the piston rod 48 and is withdrawn to a position in which a frusto-conical end 124 thereof engages a complementary seating 122 in a handle 24 secured to the rod 48. If the tyre is over inflated the hose 58 may be moved away from the seating 122 to allow air to escape from the tyre, Fig. 4 (not shown).
