A process for the manufacture of a monoaryl-substituted ethylenediamine comprises N- acylating ethanolamine, e.g. by reaction with an ester or anhydride of an aliphatic carboxylic acid, e.g. methyl or ethyl acetate or acetic anhydride, esterifying the resulting acylaminoethanol to form the corresponding acylaminoethyl chloride, e.g. by treating with thionyl chloride, reacting the latter with an aromatic amine, e.g. a primary aromatic amine at a temperature of 80-200‹ C. or a secondary aromatic amine at a temperature within range of room temperature to 150‹ C., the amino group of which contains at least one hydrogen atom, and hydrolysing the hydrochloride of the resulting N-aryl-N<SP>1</SP>-acyl-ethyl ethylene-diamine e.g. by treatment with alkali. Many primary and secondary aromatic amines are specified. In an example ethanolamine is heated under reflux with methyl acetate to produce acetamino-ethanol to which is added thionyl chloride to produce N-(2-chloroethyl)-acetamide which is then reacted with aniline to produce N-phenyl-ethylene diamine.

A longitudinally-slotted, spreadable wallplug 3 is rigidly secured in a bore, e.g. in. soft, porous masonry 1, by hardenable adhesive 5, Fig. 4 (not shown), which is introduced into the bore (before the plug is inserted) in a frangible container made of flexible plastics material. Fig. 1 (not shown), and is compressed into the surrounding material by driving in the plug so that the container is burst. To prevent the adhesive entering the plug, its slots are sealed by a U-shaped strip 6, Fig. 2 (not shown). A similar U-shaped strip 7, Fig. 5 (not shown), has cross-pieces at its edges to guide the plug into the bore 2 and is connected to a container 4a made of plastics material. In the latter case, the base of the U may be a disc, Fig. 6 (not shown), for lying transversely of the bore 2. The U-strip 7 may be welded to or interlocked with the container 4a and its ends extend from the bore to guide the plug.

Abstract: 1,053,834. Transistor logic circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 3, 1964 [Feb. 1, 1963], No. 4477/64. Headings H3T. [Also in Division H1] Logic circuits are constructed using transistors which are provided with a " base current sink " region adjacent to the collector (see Division H1) so that when the base current exceeds that required to bottom the transistor the minority carriers injected into the collector region by the base region are collected by the sink region. This reduces carrier storage and thus increases the switching speed. In the NAND gate illustrated the three transistors are connected in series and their sink electrodes S are connected together and earthed. An AND gate is also described, Fig. 4 (not shown), and is similar to the circuit shown except that the resistor is inserted between earth and the emitter of the bottom transistor from which the output is taken and the collector of the upper transistor is connected directly to the positive supply.

Abstract: 1,056,921. Counting-apparatus. LION MANUFACTURING CORPORATION. Jan. 28, 1964 [Jan. 24, 1964], No.3656/64. Heading G4D. A presettable number of coins is picked up from a hopper by an inclined plate and delivered to an exit, actuating a mechanical counter en route. A spring-mounted hopper 12 has a frustoconica! end 16 so that coins 17 drop into positions between pins 18 on a stepped plate 10, inclined to the vertical. The plate is driven by reduction gear from a motor 68. As the coins leave the plate at 21 and slide to an exit 27 they rock a lever 24 to advance a ratchet-wheel 30 with the aid of a detent pawl 33. The ratchet drives wipers over contact segments such as 51B-51D. The number of coins to be delivered is selected by closing one of switches 50A-50D. When the selected wiper runs off its contact segment the motor 68 is de-energized and solenoid 80 withdraws detent 33 so that ratchet 30 returns under spring action. The selected switch 50A-50D is also restored by solenoid 80, and kick-out lever 40 is released to dislodge coins approaching delivery position on the over-run of the motor.

[Also in Division B8] A bag making machine comprises a tubeformer and at least one bottom-folder (both not shown) and conveyer system for carrying a collapsed pile of part completed bags from the tube former to at least one of the bottomfolders, the conveyer system incorporating a magazine of endless conveyers arranged above and/or alongside each other to allow more time for glue on the part completed bags to dry. As shown the conveyer system comprises superimposed conveyer belts la, 1b pivoted to feed belts 2a, 2b which transfer the bag tubes P under pressure belts 9a, 9b to any one of superimposed magazine conveyer belts 3a-6a or 3b-6b. Extra pressure belts may be used above these magazine conveyer belts and above collector belts 7a, 7b which are pivoted to belts 8a, 8b and which enable transfer of the bags towards the bottom folder. In operation detectors L, e.g. a light barrier or a flexible feeler, sense when the uppermost magazine conveyer belts 3a, 3b are full, and stop them. The feed belts 2a, 2b then pivot to their respective next lower magazine conveyer belts and so on. The collector belts 7a, 7b pivot, similarly to the feed belts 2a, 2b, to collect bag tubes from the magazine belts and to transfer them to the belts 8a, 8b when the feed belts 2a, 2b are delivering bags to the conveyers 3a, 3b, the collector belts deliver bags from the conveyers 5a, 5b. The operation of the feed belts, magazine belts and collector belts may all be governed by the light barrier L. In a modification, Fig. 3, the bags are transferred from a pivotable feed belt 11 to a magazine belt 14 by intermeshing belts 12, 13. The belts 13 may be dependent upon the light barrier, so that they may be speeded up when transferring the last bag from the belts 12, or they may have their mountings totally, or in part, pivotable so that the last bag may be lifted clear of the belts 12. This operation may also be dependent upon the light barrier. The pivoting of the feed belt 11 stops when an actuating cam 17, on its mounting 15 acts on a limit switch 18. This process may start the magazine conveyer 14. The collector belts may also be constructed in the above " intermeshing " manner whether or not the feed belts are. Two or more conveyer systems may be used alongside each other.

Abstract: 1,232,074. Purifying magnesium chloride. NATIONAL LEAD CO. 28 June, 1968 [29 June, 1967], No. 31070/68. Heading C1A. [Also in Division C7] Magnesium chloride, for use in preparing Mg by electrolysis, is treated to substantially eliminate sulphate or other impurities therein by forming a melt of the contaminated MgCl 2  having dispersed therein active and/or colloidal carbon in amount sufficient to react with at least half the oxygen values of the sulphates, and maintaining the melt in a molten condition, without passing a chlorine-containing gas therethrough, to cause the carbon to react with the sulphates and evolve gaseous oxygen compounds. The process may be carried out as a pretreatment for electrolysis. The active and/or colloidal carbon may be formed in situ from molasses or organic matter from marine organisms, by adding the carbon-forming material to solid MgCl 2  before melting, to a solution of the MgCl 2  or to a melt of the MgCl 2 .
