Patent GB-868460-A (GB)
Title: A process for the prepartion of n.n-substituted ureas
Inventor: BRACKMAN WILLEM
Filed: 1959-09-14
Abstract: N,N1-substituted ureas are prepared by contacting carbon monoxide and oxygen with a primary or secondary amine in the presence of a cupri compound which reacts with the amine to form a complex substantially soluble in the reaction mixture.  The reaction may be carried out using an amine such as morpholine, piperidine, pyrrolidine, dimethylamine or cyclohexylamine, a water soluble cupric salt such as the chloride and a mixture of carbon monoxide and oxygen in a mole ratio of about 2:1.  Examples describe the preparation of the novel compounds di-piperidino carbonyl and di-morpholino-carbonyl. Urethane salts e.g. C5H10N.COO-.C5H10NH2\sS, may be obtained as by-products when for example, piperidine is used, if no precautions are taken to remove the water formed during the reaction.  Urethane esters may be obtained if the reaction is carried out in the presence of an alkanol.

IPC: B66C23/34
Filed: 1969-06-20
Abstract: 1,218,335. Latches. P. J. PINGON. 20 June, 1969 [30 Aug., 1968; 24 Dec., 1968], No. 31414/69. Heading E2A. [Also in Division B8] A tower crane comprises a chassis 1, a superstructure 5 with a counterweight 7 on a slueing device 6 and a mast with two elements 9, 10 hinged together at 11. The lower element 9 is hinged to the superstructure at 8 so that the mast can be folded into a horizontal position with the elements 9, 10 superimposed as shown in Fig. 1 in full lines. A carriage 14 is arranged to move along the element 9 by rotation of a lead screw 15, rods 18 being pivoted on trunnions 17 on the carriage 14 and on a pedestal 12 on the superstructure 5. The element 9 is erected to its vertical, operative position 9' by movement of the carriage 14, the rods 18 paking up a position 18'. At the same time a set of toggle lines 20, 22, 23 pivoted on the trunnions 17, to each other at 21 and respectively to the elements 9, 10 at 24, 25 causes the element 10 to assume its vertical, operative position 10'. The element 10 may be telescopic and extended further when vertical. Fig. 2 shows hows a jib 27 may automatically be moved into its operative position through tie bars 33, 34, beams 30 and hinged rod 37 connected to hinge 11 as the mast is raised. Fig. 6 shows a telescopic jib 27, 40 controlled by an endless cable 53, from a winch 54, which passes over a pair of pulleys 55 and around a horizontal pulley 56 at the end of the first jib length 27. The cable 53 is attached at 57 to the second jib length 40. A further endless cable 58 is engaged around the jib length 40 on four pulleys 59 and secured at 60 to a crane trolley 45, and at 61 to the end of the jib length 27. As telescoping occurs the trolley 45 thus moves over the jib length 40. Figs. 7, 9 show a modification wherein a telescopic jib with a second, movable length 64 longer than the first length 63 has a trolley track 72 forming an extension of a trolley. track 69 when the jib is fully telescoped (as shown in outline). The trolley 71 is moved over the track 69 by a cable (79), Fig. 8 (not shown) when the jib is fully telescoped and may run on to the track 72 where it is automatically latched to the length 64 by a hook 95 engaging a dog 101, a hook 87 being disengaged from a dog 92 by an abutment 93 engaging a lever 90 pulling a rod 89 to release length 64 from length 63. The hooks 87, 95 are respectively urged to their engaged positions by springs 91, 98.

Title: Manufacture of new azo-dyestuffs
IPC: C09B35/00
Filed: 1937-11-16
Abstract: Azo dyes are made by coupling a diazoazo-or tetrazoazo-compound which contains no OH group in o-position to the diazonium group with a compound of the general formula <FORM:0495914/IV/1> in which X signifies a direct linkage between the two benzene rings or stands for CH2 and in which the p-position to the OH group in the phenolic nucleus is occupied.  The dyes containing SO3H or COOH groups may be used for dyeing wool and the insoluble dyes may be formed on substrata, e.g. the fibre especially by the processes described in Specifications 480,358, 482,184, and 493,463 whereby the dyestuff is converted into a water-soluble acyl derivative which when treated on the fibre with a saponifying agent is reconverted into the sparingly soluble dyestuff.  In examples, the following dyes are described: (1) 4-amino3 : 21-dimethylazobenzene --> 4-benzylphenol, 4 - oxydiphenyl, 4-methyl - 2 - benzylphenol or 3-chloro-4-oxydiphenyl; (2) 4 : 41-diamino-21-methyl-51-methoxy-1 : 11-azobenzene \sQ the same components as in (1) and also 3-bromo-4-oxydiphenyl; (3) 41 - chloro - 21 - nitrophenyl-1 : 11-azo-3-methoxy-4-aminonaphthalene --> 4-benzylphenol; (4) and (5) the azo dye 4 - amino - 3 : 21 - dimethylazobenzene --> 4-benzylphenol is heated with benzoic acid-3 : 5-disulpho chloride in pyridine and the water soluble product made into an aqueous paste with starch tragacanth and thiodiglycol, printed on cotton, and the latter dried, steamed and developed by passage through sodium hydroxide solution (yellow brown).

Abstract: 885,137. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 13, 1960 [Sept. 16, 1959], No. 31494/60. Class 37. A semi-conductor device has an electrode comprising aluminium which has been coated by electroless plating with a layer of nickel and/or cobalt. In one example, an aluminium electrode 2 (Fig. 5), is fused to a P-type silicon wafer 1 at 780‹ C.; the whole is then etched in nitric and hydrofluoric acid, washed and placed in an electroless bath of nickel chloride, sodium hypophosphite, ammonium chloride, sodium citrate and water for 15 minutes at 90‹ C. to provide a nickel coating. Alternatively, cobalt may be applied utilizing a bath of cobalt chloride, sodium hypophosphite, Rochelle salt, ammonium chloride and water. The electrode is then tin-soldered to a support 6 and the nickel coating removed from the opposite surface of wafer 1 to which a point contact 7 or one or more other electrodes may be applied. The assembly is then sealed in an envelope 8. In a second embodiment a rectifying contact is provided by alloying an oxide-coated aluminium wire 11 (Figs. 13 and 14) to an N-type silicon body at 750‹ C. in hydrogen. The assembly is etched in HF and HNO 3  to remove the oxide film, and placed in an electroless plating bath as before to provide a nickel coating over the wire and the silicon. To remove the nickel from around the NP junction perimeter, a portion of the wire is plated with tin 17 and wax 22, and the opposing surface of the silicon is stuck with wax 18 to a glass plate. The rectifier is then etched in HF and HNO 3  which removes the nickel from the unprotected surfaces. Fig. 14 shows the completed device with wire 11 with endcoating 17 of nickel and tin connected to a ferro-chromium tube 27.
