Heading C2C. α - Amino - # - lactams having the general formula in which n is an integer of 1-8, are produced by subjecting α-aminocycloalkanone oximes of general formula to a Beckmann re-arrangement in the presence of chlorosulphuric acid or sulphur trioxide as catalyst. If desired, instead of chlorosulphuric acid a mixture which yields it under the reaction conditions may be used. Either the free oximes or their mineral acid addition salts may be used. If a free oxime is used a mineral acid may be added to the reaction mixture. The lactams obtained may be hydrolysed to give α,#,-diaminocarboxylic acids, e.g. α-amino-#- valerolactam gives ornithine, α-amino-#-caprolactam gives lysine and α-amino-# -laurolactam gives α,#-diamino lauric acid. Examples are given of the preparation of α-amino-#-caprolactam and α-amino-#-laurolactamhydrochloride in the form of their hydrochloric acid addition salts. The laurolactam hydrochloride is hydrolysed to give α,#-diamino lauric acid hydrochloride.

Abstract: 1,216,316. A pin wheel data store. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 17 Jan., 1969 [8 Dec., 1967], No. 55898/67. Heading G4B. [Also in Division B8] A pin wheel data store element consists of two magnetic discs 1, 2, mounted on a shaft 3 and carrying a series of pins of magnetic material 7 whereby each of said pins is capable of being held magnetically in either one of two positions relative to said support members. Magnets 4 are disposed between the two discs such that they are symmetrical with respect to the shaft and all south poles are in contact with one disc, and all the north poles are in contact with the other. The pins are located so that one end is flush with one of the discs in either of the preferred positions, these representing the "1", "0", binery digits in the store. The disc rotates in direction A and as the pins 7 pass wedge 9 the ramp 8 returns them to the "0" position. Plate 10 prevents irregular positioning. To read data into the store lever 11 (pivoted at 12) is either operated electromagnetically to push a pin through the discs to record "1", or remains inoperative to record "0". Read out is by a microswitch positioned so that a pin in the "1" position will strike it, while a pin in the "0" position will not. A further embodiment, Fig. 4 (not shown) contains four magnetic discs supporting the pins so that there is also a "null" position for the pins. The device can be used to control a conveyer belt system.

Filed: 1972-12-12
Abstract: 1371980 Refrigerating SARLAB AG 12 Dec 1972 [22 Dec 1971] 57210/72 Heading F4H In a continuous cycle absorption refrigerating system operating with an inert gas, a liquid heat exchanger utilizes the heat from refrigerant vapours produced in or by a generator before they pass to a condenser (not shown) through a pipe 29 to heat cold rich absorption solution flowing to a liquid circulation pump 15 from an absorber vessel 23 through a conduit 24. In operation of the apparatus, the rich solution is at a higher liquid level 38 in the absorber vessel than a level 20 in a reaction column 21 for the pump 15, the lower level 20 being dependent on the interaction between liquid flow restricting means in the conduit 24 and the capacity of the pump. The liquid flow restricting means may comprise a spiral wire or groove (not shown) within the conduit 24 or a space 39 formed in the liquid heat exchanger by an inverted V or U formation of the conduit 24 which is effective to collect inert gas and vapours to produce a bubble or liquid level 42 which inhibits the flow of rich solution therepast. The portion 26 of the conduit 24 downstream of the restricting means is in heat exchange relationship with a conduit 27 through which the vapours from the pump 15 and conduit 19 flow in countercurrent. The conduits 26, 27 may be connected together at a point 41 where, during normal operation, the rich solution is close to its boiling point to enable vapours generated therefrom to combine with the vapour in the conduit 27 and any condensate formed in the conduit 27 to flow back to the vapour generator in countercurrent to the vapours. Alternatively, the conduits may both terminate adjacent the reaction column 21 above the liquid level 20. A conduit 36 through which weak solution from the generator to the absorber (not shown) together with the conduits 26, 27 may be concentrically mounted, wound in a coil or of flattened cross-section.

Abstract: 1285717 Windscreen wiper control JOSEPH LUCAS (INDUSTRIES) Ltd 20 Nov 1969 [6 Dec 1968] 58156/68 Heading A4F A switch for controlling a self parking windscreen wiper motor, has a stable on position and an on position from which it is resiliently urged to the off position. The switch comprises a body 11 having a compartment 12, a contact member 14 having a central part 15 rotatable in the body 11 and having two arms 16 and 17, and a second contact member 25 pivoted half way along arm 16 and extending over arm 17. Sets of resilient contacts 18, Fig.1 (not shown) and 27 respectively are provided on arm 16 and member 25, and cooperate with a printed circuit board 32 for switching. Each arm 16 and 17 carries a spring-loaded ball engaging detent means in the body 11, Fig.1 (not shown). Contact member 25 has a groove 28 in which is located a spring 29 engaging a post 31 on arm 17 to urge member 25 clockwise relative to arm 17 in Fig.2 until it abuts flange 20 on the contact member 14. A contral level 19 is fastened to a block 21 passing through and pivoted at 22 to the centre port 15 of contact member 14. A post 23 on port 21 extends through an aperture 26 in member 25 and through a rectangular slot in centre part 15 of member 14. A spring- loaded ball 24a engaging hole 33 in printed circuit board 32 urges post 23 to the right in Fig.4 and thus reinforces the action of spring 29. If lever 19 is turned either clockwise or anti-clockwise in Fig.3, contacts 18 or 27 co-operate with circuit board 32 to operate the wiper motor, member 25 moving with arm 17 by virtue of being held in contact with flange 20 by spring 29. One set of contacts may operate the motor at a different speed or with a delay between wipes. If lever 19 is moved instead into the paper, post 23 causes member 25 to move anti-clockwise, arm 17 remaining stationary, and contacts 27 co-operate with circuit board 32 to switch the wiper on. On releasing lever 19, springs 29 and 24 cause contact member 25 to move clockwise to disengage contacts 27, and the wiper stops after reaching its parking position. Case 11 has a slot 34 which allows lever 19 to move into the paper in Fig.3 only when the lever is in the central position as shown.

A spacer as described in the parent Specification 1,147,233 has the springs in the form of bent strips of varying width in order to provide decreased coolant flow resistance. A flat sheet metal blank for manufacturing one fuel rod location of a spacer according to the invention is shown in Fig. 2, the grid parts of the spacer being designated 1 and the spring parts 2. The blank is first bent so that the spring parts 2 obtain transverse protuberances midway between their ends, and is then bent to form a body in which the grid parts 1 each adopt a square configuration with bevelled corners, this body being intended to house one fuel rod. The whole spacer is then built up of such bodies. The protuberances in the spring strips 2 are formed by bending the latter at the lines 3, 4 and 5 so that the portion immediately adjacent to the line 4 forms the top of the protuberance, this being the part which abuts the fuel rod. The strips 2 are widest immediately before and after the protuberance and have a somewhat narrower abutment head at the top of the protuberance. Those portions of the grid parts 1 from which the strips 2 extend are wider than the intermediate portions.
