Abstract: 806,598. Automatic position control systems. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 4, 1956 [May 4, 1955], No. 12906/55. Class 38 (4). [Also in Group XVI] An apparatus for transversely guiding a moving strip 1 comprises a roller 3 around which the strip passes, the roller being tiltable about the normal centre-line A-B of the oncoming strip, and means for detecting lateral deviations of the strip and for initiating the operation of means for controlling the degree of tilt of the roller. Lateral deviations of the strip 40, Fig. 5, are detected photo-electrically by a receiver 42 co-operating with a light source 41 so positioned that part of the light emitted is interrupted by the strip 40 and part energizes a photo-electric cell forming part of the receiver. The receiver 42 includes an electric bridge circuit containing the photo-cell in one arm, this circuit being balanced and the output from the receiver being zero when the strip is in correct lateral position. The receiver 42 is connected to an amplifier 43 which controls the speed and direction of an electric motor 44. The motor 44 drives a shaft 45 carrying a pinion 46 meshing with a pinion 47 on a screwed shaft 48 secured at one end to a bracket 50 on a frame 51 carrying a strip-engaging roller, not shown. Lateral deviations of the strip cause rotation of the motor 44 in the appropriate direction, thus tilting the roller to return the strip to its desired path. The shaft 45 drives a tachometer generator 53 which is connected to the amplifier. The tachometer generator transmits a signal to the amplifier 43 proportional to the speed of the motor 44, thereby preventing over-running of the motor due to its own inertia.

Title: Improvements in or relating to the manufacture of onium salt complex compounds
IPC: C07F5/00
Filed: 1964-03-26
Abstract: Onium salts having a complex anion are prepared by the reaction of (a) an electron donor compound of formula R1kHlkY, (b) a electron acceptor compound of formula MR11nX1mn and (c) an organic compound RX, wherein R, R1 and R11 are alkyl or aryl groups, X is halogen, pseudohalogen or an acid residue, X1 is halogen or hydrogen, Y is N, P, As, Sb, Bi, S, Se or Te, M is Be, Zn, Cd, B, Al, In, Ga, Tl, Si, Ge, Pb or Sn, l and m are integers representing the capacities of Y and M respectively to combine with hydrogen, and k and n are 0 or an integer from 1 to l or m respectively. The reaction in its simplest form may be represented by:-D + A + RX --> [DR]+[AX]-wherein D represents the electron donor and A the electron acceptor, but compounds formed by the reaction of two molecules of acceptor with one each of donor and RX ar also disclosed. The reaction may be carried out by first forming a co-ordination compound between donor and acceptor and reacting this with RX, or an adduct or mixture may be formed from the acceptor and RX which is then reacted with the donor, or the donor and RX may be first mixed and then reacted with the acceptor. Trimethylammonium triethylchloroaluminate obtained by first passing triethylamine gas into triethylaluminium to form a 1 : 1 complex and passing methyl chloride into the product.  By passing further methyl chloride there is obtained the complex <FORM:1062464/C2/1> Triethylpropylstibonium triethylbromoindanate is prepared by reacting methylantimony and triethylindium under an inert gas and adding N :propyl bromide to the product.  Further examples are indicated by the equations:- <FORM:1062464/C2/2> <FORM:1062464/C2/3> <FORM:1062464/C2/4> The complex onium salts may be degraded by such methods as solvolysis with methanol or water, oxidative cleavage or displacement with a stronger complexing agent for the acceptor compound to give the simple onium salt (DR)+X- where D represents the donor compound. For example, tetraethylstibonium triethyl bromoaluminate in solution in dichloromethane is added to methanol, ethane is evolved and aluminium methoxide removed by decantation, and the residue worked up to yield tetraethylstibonium bromide.
