Title: Process for the preparation of a salt of optically active lysine
Inventor: SUVERKROPP G
IPC: C07C227/36
Filed: 1968-12-11
Abstract: 1,245,436. Lysine-phenoxyacetic acid salt. STAMICARBON N.V. 11 Dec., 1968 [16 Dec., 1967], No. 58843/68. Heading C2C. The invention comprises the mono salt of lysine and phenoxyacetic acid, preferably the optically active salt. The salt is prepared by conventional salt-forming methods, e.g. by reacting racemic lysine with phenoxyacetic acid in aqueous solution, followed, if desired, by resolution into the D-and L-antipodes by seeding a supersaturated solution with the desired optical antipode, the remaining antipode may then be racemized by heating in aqueous solution and the resolution repeated. Alternatively, the solution containing the remaining antipode may be saturated with the racemic salt of lysine and phenoxy-acetic acid, whereupon the remaining antipode separates out, since the D- and L-forms are insoluble in a saturated solution of the racemic salt.

Patent GB-758196-A (GB)
Abstract: 758,196. Recording apparatus. TELEPHONE RENTALS, Ltd. Aug. 26, 1954 [Sept. 3, 1953], No. 24394/53. Class 106 (4). Means for aggregating the running or idling time of a machine and the idling time due to any one of a plurality of particular cause comprises a number of time registering meters responsive to selective signals transmitted from the machine. The meters may consist of one, TP for productive time, one TL for lost time, on UA for unallotted time and a number A1-A0, each for recording time lost due to a particular cause. The meters may be operated by a pulse generator PG. At the commencement of a working shift a switch SW is closed and pulses reach the meters TL and UA. When the machine M starts, a relay P is operated to close a switch P1, bringing meter TP into operation and open a switch P2 cutting out meters UA and TL. In the event of the machine stopping this last operation is reversed and meters UA and TL again register. The machine operator must now signal the cause of the stoppage and in one embodiment, a number of causes are set out on a telephone dial D, the operator dialling the particular cause to send pulses to the driving magnet SDM of a uniselector switch, the wiper S1 of which travels to the contact connected to the meter allocated to the particular cause. The moving of the wiper S1 from its home position breaks the circuit through the meter UA. Means are provided for cancelling a first dialled cause of stoppage and substituting another. Embodiments are described in which, in lieu of a telephone dial, a series of keys is provided, each bringing in a particular one of the meters A1-A0.

Patent GB-766188-A (GB)
Abstract: 766,188. Calculating-apparatus. ELDIFEINMECHANIK GES. June 8, 1954 [June 8, 1953], No. 16715/54. Class 106 (1). [Also in Group XVI] The keys of a, typewriting calculating- machine displace members controlling contacts arranged to enter the corresponding digits or letters in the machine, an actuated member being electromagnetically retained in displaced position until the corresponding registration has been effected, but the key being free to return. On depression of a number key 20, a corresponding bar 5 is displaced by means of a plunger 21, acting as a seal for the casing 1, and a lever 18. The bar 5 allows two pairs of contacts 7 to close, one of which prepares circuits through one or more number relays, Fig. 1 (not shown), representing the numbers 1, 2, 3 and 5, to register the digit in coded form, and the other of which completes a circuit for a control magnet 14. Alternatively, the latter may be energized through a single contact pair closed by a transverse member actuated upon displacement of any bar 5. A bail 12 rocked by the magnet 14 co-operates with notches 10, 11 in the bars 5 to complete, if necessary, the displacement of the actuated bar and to lock all the bars against further movement. The magnet 14 also displaces through an arm 44 a bar to allow a further contact pair 7 to close to complete the prepared number relay circuits. The energized number relay or relays complete a circuit through the appropriate one of a set of magnets 30 or a space magnet. The armature lever 31 of the energized magnet 30 raises a plunger 42 to engage the corresponding type lever with electrically-driven actuating mechanism. The number relays effect entry of a number into the calculating mechanism and may also be energized under the control of the latter to control the energization of the magnets 30. The ends of the armature levers 31 are supported in comb plates 28, 29 which may be laterally displaced by a magnet under carriage or key control to cause the levers to operate the plungers 42 or levers 25 or both. The levers 25 respectively operate the bars 5 which by means of differentiallyextending end-pieces 4 set indicators 3. The circuit of the selected magnet 30 is completed by contacts controlled by the calculating- machine and the control magnet 14 is deenergized under the control of the machine.
