Abstract: Method for the optical reaction of D-and-L-alpha-amino-caprolactam (D and L-I), wherein DL-I is mixed with beta-naphthalene-sulphonic acid (II) or 2-naphthylamine-1-sulphonic acid (III) in a suitable warm solvent or solvent mixture eg. H2O, (1-5C) alkanol, (2-4C) alkyleneglycol, l. ether, l. carboxylic acid, di (l. alkyl) amide, etc., pref. a mixture of H2O and organic solvent in ratio 10:90 - 70:30, cooled, and seeded with one of the optical isomer salts (eg. D-I-II). If the mixture is already partly resolved, it is pref. seeded with the isomer present in excess. When crystallisation is complete, the product is filtered, and the mother-liquor seeded with the second isomer, the isomer isolated, and the filtrate recycled with more DL-I and acid. The resolved products may be purified by recrystn., and the sulphonic acid removed by treatment with ion exchange resin or inorganic base. The optically active lactam (I) or the salts, can be hydrolysed, e.g. by HCl to give D or L-lysine. The isolated D-I-sulphonate can be racemised by heating at 200-250 deg. under N2 or CO2, and recycled. Intermediates for lysine.

Abstract: 1,052,538. Casings for electric motors; fluid actuation of switches. FRANKLIN ELECTRIC CO. Inc. April 8, 1964 [Aug. 13, 1963], No. 14604/64. Headings H2A and H2B. [Also in Division G3] The operation of motor 10, used to drive a pump is controlled in accordance with liquid level by switch 43 which operates as float 21, enclosing both motor and switch, rises and falls. The conventional over-centre snap-action switch 43 is mounted on carrying handle assembly 29 which in turn is attached to bosses 34 on the motor end bell by screws 39 and is operated by saddle 66 which is rigidly attached to float 21 such that with operating arm 44 down, the motor is switched-off. As the liquid level rises the float rises until arm 44 contacts spring-loaded stud 71, further rise of liquid causes arm 44 to be lifted still further until the switch snaps over and the motor is switched-on. As the liquid level falls, arm 44 drops down until it switches the motor off, the operating point of the switch being adjusted by altering the compression of spring 79. Flexible seals 40, 26 at the top and bottom of the float are used to seal the float to the motor/switch assembly, whilst allowing vertical movement of the float. The handle and switch assembly are mounted to be easily removed for maintenance by unscrewing screws 39.

Abstract: 1,230,340. Discharging liquids. HONEYWELL Inc. Nov.24, 1969 [Nov.26, 1968], No.57409/69. Heading F1R. [Also in Division H1] In a rupturable sealing arrangement, (Fig.2A), a flexible diaphragm 25 e.g. cold finished sheet steel, is provided across an opening 22 so as to prevent the passage of fluids otherwise than when it ruptures in response to a sufficient fluid pressure difference applied across it, and the opening 22 has a first diameter where the diaphragm 25 is disposed across it and a second smaller diameter adjacent to and spaced from the diaphragm, the progression from the first to the second diameter being abrupt so as to define an annular edge 26 so that diaphragm 25 impinges on it when flexed by an applied differential pressure which has a magnitude less than that required to rupture the diaphragm. The diaphragm ruptures when the pressure exceeds a predetermined value. The sealing arrangement can be used in a deferred-action battery Fig.1 to initially seal off the activator compartment 11 containing the electrolyte solution or solvent in a compressible container from the battery compartment 12 by providing it in the bulkhead 13 which separates the two compartments. The diaphragm 25 is held in place in a recessed opening in bulkhead 13 by an annular collar 27. The diameter of opening 22 defined by bulkhead 13 and collar 27 is enlarged for a short distance on either side of diaphragm 25, the enlarged portion of collar 27 giving rise to the annular edge 26 at its internal diameter. The battery is activated by rupturing diaphragm 25 and forcing the electrolyte into compartment 12 by means of the percussion actuated gas generator mounted in cover 15. A pull on hammer release mechanism 34 operates hammer 33 which strikes firing pin 32 which acts against primer 31 to cause a detonation which ignites gas generating squib 30. The gases are forced into compartment 11 and the pressure developed on the compressible electrolyte container is transmitted to diaphragm 25 which bursts.

Abstract: 1,237,910. Lasers. PERKIN-ELMER CORP. 21 Nov., 1968 [5 Dec., 1967], No. 55274/68. Heading H1C. In order to maintain the end mirrors of a laser resonant cavity in correct alignment the output signal from a photo-detector indicative of changes in the transverse position of the laser beam is used to servo-control the position of one of the mirrors. A D.C. excited argon gas laser 11 comprises a gas tube 12 located in a resonant cavity defined by a pair of mirrors 15, 16 mounted on support rings 17, 25 respectively and provided with vertical and horizontal adjustment screws and springs 21, 23, 24 and 27, 28 respectively, the horizontal screw and spring for mirror 16 not being shown. Light from partially transmitting mirror 16 falls on a four quadrant detector 31 precisely aligned along the optical axis of the laser and symmetrically disposed about a centre point 0. When the mirrors 15, 16 are precisely aligned equal amounts of light from the beam B fall on each of the four detector units and no signal is passed to the horizontal 36 and vertical 38 amplifiers. If any misalignment between the mirrors occurs a corresponding axial shift in the light beam B follows and outputs from the vertical and horizontal pairs of quadrants will be produced. The outputs from the detector units 32 to 35 are fed to differential amplifiers 38, 36 as shown which produce output signals whose polarity and magnitude correspond to the direction (i.e. left or right or up or down) and the amount of shift of the light beam. These output signals are fed to motors 39, 37 coupled to drive the biased screws 21, 23 respectively to control the vertical and horizontal positions of mirror 15 and maintain the mirrors in alignment. The electric motors may be magnetostrictive elements and instead of the laser beam being emitted through both mirrors a single output beam may be split into two parts.
