Title: Improvements in or relating to the purification of lysine
Inventor: HAUSE NORMAN LAURANCE
Filed: 1958-02-25
Abstract: Lysine which has been racemized and which contains impurities, such as alpha-amino-epsilon-caprolactam, deleteriously affecting its resolution, is purified by heating it with an aqueous solution of a strong mineral acid, thus producing a lysine capable of more ready resolution.  The crude racemized lysine may be obtained by heating optically active lysine with a cation-exchange material, as described in U.S.A. Specification 2,536,360.  Specified mineral acids are phosphoric, sulphuric and hydrochloric acids and mixtures of two or more such acids.  The concentration of the acid may range from 1 to 50 per cent by weight, that of hydrochloric acid being preferably from 1 to 37 per cent by weight.  Preferably from 1.2 to 8 mols. of mineral acid are used per mol. of lysine, the concentration of the lysine in the reaction medium being preferably from 0.5 to 70 per cent by weight, based on the weight of the lysine solution, before addition of the mineral acid.  The heat treatment may range from 70 DEG  to 220 DEG  C. for a duration of 1 to 24 hours.  The above purification treatment can be carried out in conjunction with the mineral acid hydrolysis of lysine-yielding intermediates, such as poly-3:5-tetramethylene hydantoin and 5-(delta-aminobutyl) hydantoin, to produce DL-lysine.  Thus the crude racemized lysine may be mixed with the lysine-yielding intermediate and the mixture heated with the mineral acid to produce resolvable DL-lysine from the intermediate and resolvable DL-lysine from the crude racemized lysine simultaneously.  The examples describe the treatment of lysine which has been racemized by the method of U.S.A. Specification 2,536,360 and its subsequent resolution with L-glutamic acid.

Filed: 1926-03-04
Abstract: 249,109. Silica Gel Corporation, (Assignees of Miller, E. B., and Edel, W. L.). March 11, 1925, [Convention date]. Refrigerating, vacuum systems for. - In systems wherein the vapour of a liquid such as brine or water is adsorbed by a porous solid adsorbent such as silica gel, activated charcoal, or gels of oxide of tin &c., as set forth in Specifications 225,191 and 228,136. the vapour is rejected from the adsorbent to the atmosphere during the reactivation of the adsorbent, the process involving alternate adsorption and reactivation being effected without the use of a condenser or pumps. The apparatus comprises a vessel 10, in which the refrigerant liquid is deprived of contained air by heating, a stop valve 13, a cold evaporator 11, a check valve 14, an adsorber 12 and heater 16, and a vent valve 15. The system is first freed of contained air by applying heat to the evaporator 11, the valve 13 being closed, the vapour ultimately escaping through the valve 15. Heat is then applied to the adsorbent to free it of adsorbed vapour, which escapes through the valve 15, after which the adsorber is allowed to cool, the valve 15 closing. When the evaporator 11 is put into refrigerating use the vapour given off passes through the valve 14 and is adsorbed. At the end of the refrigerating period the heater 16 is applied to reactivate the adsorbent, the valve 14 closing against the return of vapour to the evaporator and the vapour being rejected to atmosphere through the valve 15. The valves 14, 15 may be manually controlled, or these valves and the heater 16 may be operated by thermostatic means. The evaporator may be replenished occasionally by opening the valve 13.

Title: Improvements in visual indicators for distinguishing between two signals of rectangular wave form particularly for radio blind approach systems
IPC: G01S1/02
Filed: 1942-05-11
Abstract: 579,072. Wireless blind approach systems. STANDARD TELEPHONES & CABLES, Ltd., and WESTON, J. D. May 11, 1942, No. 6386. [Class 40 (v)] Means for visually distinguishing between electrical signals of the same rectangular waveform but of opposite sign, particularly applicable to radio blind approach overlapping beam systems, comprises means for obtaining from the signals a comparison signal of constant sign irrespective of the sign of the received signals and for combining it with the original signal in a differential rectifier, the directcurrent output from which is applied to an instrument which indicates the direction of the current. As shown, complementary dot and dash signals a, b are obtained by demodulation of the carrier in the valve V, and after removal of the direct current component by means of the filter R1, C1 (as shown at c and d) are applied to a rectifier bridge RB, a resistance R2, and the indicating instrument A, arranged in series. The wave-forms c, d are the same, but of opposite sign. The bridge rectifier produces from either form the voltage indicated at e across the primary L of a transformer T, resulting in voltages f of opposite sign in each half of the centre-tapped secondary, these halves being each in a separate series circuit including R2, the instrument A, and rectifiers W1, W2 respectively. In one of these circuits, according to whether signals c or d (derived respectively from dots and dashes) are applied across R2, the voltages in R2 and the associated half of the secondary winding will be additive, and in the other in opposition, the difference in the latter case being preferably made substantially zero by suitable choice of the value of R2. Thus the instrument A receives a series of pulses rectified either by the rectifier W1 or W2, the direction of which is dependent upon whether dot or dash signals prevail. In a modification the transformer is replaced by a resistance-condenser network. Specification 526,114 is referred to.

Abstract: 692,597. Retractive switches. DUNGLINSON, B., and HOPK1NSON, A. F., [trading as ARCASON CO.]. March 27, 1951 [March 23, 1950; March 23, 1950], No. 7126/51. Class 38 (v) [Also in Group XXIII] A'rotary switch 62 controlling the motor in a dishwashing machine (see Group XXIII) comprises a hollow annular glass envelope containing mercury up to a level 76, and contact wires 78, 80, of which 78 is the longer, mounted in the envelope and arranged so that one or both may be in contact with the mercury according to the rotational position of the switch. The switch is enclosed in a two-part insulating casing surrounded by two slip rings 74 connected by leads 82 to the contact wires and by brushes 84 to the motor circuit. Rotation of the switch and its casing is effective by the shaft 66 of a clockwork 60 windable manually by a knob 64. To operate the machine the pointer 112 of the knob 64 is rotated manually from the zero position to either of positions 1, 2 or 3, within an arc 110 on an index plate 68 and thus winds the clockwork. Within this arc the contact wire 80 is always in contact with the mercury and the amount of immersion of the wire 78, and hence the duration of washing, is varied according to the position of the knob. The motor is thereby energized and when the knob is released the clockwork rotates the switch with a retarded movement in the opposite direction. When the knob reaches the end of the arc 110, the contact wire 78 leaves the mercury and the motor stops, the washing cycle thereby being ended. After further rotation the switch remakes in the arc 114 to re-energize the motor and effect the shorter rinsing operation. When the knob leaves the arc 114 the motor again stops and the rinsing cycle is completed. An additional contact wire may be provided for effecting a second rinsing cycle of constant duration.
