Title: Improvements in method of producing carboxylic substituted aliphatic amines and metallic salts thereof
Filed: 1949-01-08
Abstract: Carboxylic substituted aliphatic amines are made by forming an aqueous reaction solution containing a known weight of an aliphatic compound having at least one replaceable amino hydrogen atom, a smaller quantity of an alkali metal cyanide and an alkali metal hydroxide sufficient to produce a pH of at least 8, heating the solution to 60-100 DEG  C., under reflux, and a low positive pressure to exclude atmospheric gases, adding aqueous formaldehyde, hydrogen cyanide, and alkali metal hydroxide solutions at such rates that the formaldehyde concentration is less than the alkali metal cyanide concentration at any one instant, and that the alkali metal cyanide content and the pH remain substantially constant, terminating all three additions when the alkali metal ion content of the solution, the cyanide ion content, and the formaldehyde content all approximate one ion or molecule per amino hydrogen atom to be replaced, and finally, heating the solution above reaction temperature but not over 120 DEG  C. to complete reaction and expel residual ammonia.  An example described the adding to an aqueous solution of ethylene diamine, sodium cyanide, and sodium hydroxide having a pH of 8, of formaldehyde solution, liquid hydrogen cyanide, and aqueous caustic soda solution, giving the tetrasodium salt of ethylene diamine-N,N1-tetra-acetic acid.  Potassium, lithium, or caesium hydroxide may also be used.  Acid salts of the tetra-acetic acid may be obtained by reducing the amount of alkali metal hydroxide, and polymetallic salts may be obtained by adding any basic metal compound, e.g. copper oxide or hydroxide, to aqueous solutions of the di- and tri-alkali metal salts.  Mono-, di-, tri-substituted amino acid, products, e.g. mono-, di- and tri-acetic acids from ethylene diamine may also be obtained. Specification 600,629 is referred to.

Abstract: 1,193,901. Barrier actuated by fluid pressure. GODWIN WARREN ENG. Ltd. 6 Jan., 1969 [5 Jan., 1968], No. 769/68. Heading E2M. [Also in Division F1] A barrier 11 which lies flush with the ground to bar access, is operated by piston-cylinder when not in use, and is raised about pivots 12 units 15, and has a locking device 19, operated by piston-cylinder unit 20, which prevents unauthorised lowering of the barrier to its inoperative position and remains operative even if the fluid supply lines are sabotaged. Raising of the barrier by the main fluid system (double lines Fig. 4) causes operation of a detecting valve 22 in the auxiliary fluid system (single lines Fig. 4) which in turn causes operation of a valve 36 in the main fluid system to cause the bolts 19 to be extended to underlie the bottom margin of the front shroud 17 of the barrier. Thus if the fluid supply line 32 is cut to depressurize the main fluid system the barrier will be lowered slightly, but will then rest on the bolts.

Title: Improvements in or relating to electric wave filters
Inventor: CAMPBELL CHARLES FRANCIS
IPC: H03H7/01
Filed: 1953-01-13
Abstract: 740,465. Impedance networks. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Dec. 30, 1953 [Jan. 13, 1953], No. 954/53. Drawings to Specification. Class 40 (8). A method of compensating for the difference between the theoretical and actual transfer characteristics of a filter or like 4-pole network due to self-capacitance of the inductive elements, consists in substituting a series resonant circuit for each capacitative element in the ideal form of the network, the additional inductor required to complete such resonant circuit being so chosen as to contribute an effect upon the transfer characteristics of the filter which differs from that contributed by the original capacitative element by an amount substantially equal and opposite to the effect of the self-capacitance over the range of frequencies to be passed by the filter. The transformation can be expressed as a substitution of the expression Ap/p<SP>2</SP> + B for p (= J#) in the formulae used in the calculation of the network. By suitable choice of the constants A and B it can be arranged that the characteristics of the resultant network differ only slightly from those of the original theoretical network. The substitution is also valid for additional sections included for line impedance matching.
