Title: Process for the production of n-substituted formamides
IPC: C07C233/16
Filed: 1954-06-24
Abstract: N-Alkylol-substituted formamides are prepared by reacting in the absence of water and at an elevated temperature and pressure a primary alkanolamine with carbon monoxide in the presence of a carbonyl-forming catalyst containing nickel or cobalt or compounds of these metals.  Specified catalysts are metallic cobalt and nickel, their carbonyls (including dicobalt octacarbonyl), oxides and salts with organic and inorganic acids. The reaction is preferably carried out in the temperature range 125-300 DEG  C., and at a gauge pressure of between 2000 and 15,000 lb/sq. in.  The catalyst may be used alone or in conjunction with a promoter, particularly hydrogen iodide, preferably present in amounts between 5 and 10 per cent by weight of the catalyst.  In examples: (1) aminoethanol, nickel acetate and HI are treated with CO in a high-pressure reaction vessel at 175 DEG  C. to give N - (2 - hydroxyethyl) - formamide; (2) as in (1) employing higher pressure and temperature; (3) as in (1) but using dicobalt octacarbonyl as catalyst, without a promoter.

Abstract: 915,534. Bushing insulators; capacitors. BRITISH INSULATED CALLENDER'S CABLES Ltd. May 25, 1961 [May 26, 1960], No. 18664/60. Classes 36 and 37. A bushing insulator for making high voltage connection to apparatus in a fluid-tight tank comprises an insulating body formed with a head and a neck portion, and a metal easing similarly shaped which supports the insulating body. An insulator for mounting in the lid 21 of a capacitor tank comprises a ceramic body 18 fitted within a metal casing 34 which screws into a mounting 20 soldered to the lid 21. The ceramic 18 projects below its casing 34 and cooperates with a neoprene ring 24 in the mounting 20 to make a fluid-tight joint of the kind disclosed in Specifications 692,627 and 702,608. A tubular conductor 27 fits within the ceramic body 18 with the aid of further neoprene rings 30, 31 and receives within itself a central terminal 29. The insulator is circular in crosssection but a flange 35 is square and has holes 38, 39 and slots 37 for interconnecting adjacent insulators. The perforated edges of the flange may be chamfered for co-operation with an adjacent flange. The neck of the ceramic body may be shortened, the metal casing then being screwed directly down on to the neoprene ring and a further ring being inserted between the ceramic neck and its metal casing. The metal casing may instead be soldered directly to the capacitor tank lid. Adjacent bushings may be interconnected (Fig. 6) by a metal plate 43 screwed to adjacent flanges and by a second plate 50 joining the conductors 52. The plates are separated by an insulating foil layer 49 and by an insulating packing 48 in a circular aperture in the plate 43 coinciding with each ceramic body. The plate 43 may be omitted and the flanges joined directly by their perforated edges.

Abstract: 169,812. Haines, L. F. July 6, 1920. Dynamos, stopping automatically; dynamos, regulating.-Electric installations comprising turbines or other prime movers are provided with automatic stopping, starting, or regulating apparatus of the kind shown in Fig. 1, which operates by the fall of a weighted wedge B when released by momentary energization of an electromagnet C, so as to cause a longitudinal movement of a rod A which deflects a water jet or otherwise acts upon a prime mover. The magnet C is, in one arrangement shown in Fig, 4, connected in circuit with a generator E and lamps M, but is kept short-circuited, during normal working, by a two-way switch actuated by an electromagnet D. If the generator fails, the switch moves from contacts 1, 2 to contacts 3, 4, momentarily energizing C during its passage. The switch and release may be combined into one device. The deflected rod A may operate a valve by the release of a winding drum wound with a weighted cord.

Abstract: 335,603. Chorlton, A. E. L., Haig, R. A. de H., and Stieger, H. J. June 27, 1929. Planes, construction of.-In aeroplanes having cantilever wings, the wing tip is stayed against torsional stresses by securing a stiff cross rib B to the cantilever spar A at the point where the spar commences to taper and by providing a diagonal spar C connecting the outer tip of the tapering extenion A<4> to the after portion of the cross rib B. In one arrangement, in which the spar A is stayed against torsion by pyramidal bracings A<1> and struts A<2>, the after portion of the rib B is braced against drag stresses by a strut F and drag wire G. An aileron may be hinged to the spar C which may then be connected to the rib B at a point nearer to the spar enabling the aileron to be included in the wing , tip; the strut F is in this case also attached to rib B at a point coinciding with the end of spar C. According to further modifications the spar C may form the leading edge of the aileron and be hinged to the ends of the wing tip ribs or alternatively these ribs may extend to the rear of spar C to carry the aileron hinges.
