Abstract: 1290850 Salts of cyclohexyl sulphamic acid ALBRIGHT & WILSON Ltd 17 Nov 1969 [15 Nov 1968] 54395/68 Heading C2C A process for the production of salts of cyclohexyl sulphamic acid comprises (1) reacting cyclohexylamine with a complex of sulphur trioxide and a trialkyl or triarylphosphate or phosphite in an inert organic solvent immiscible with water, (2) contacting the product with water to form aqueous and organic phases, (3) causing the product in the aqueous layer to react with a desired base as defined below and (4) separating the aqueous and organic phases. A desired base is defined as one which is stronger than cyclohexylamine and whose salt of cyclohexylsulphamic acid has a partition coefficient between water and the organic solvent employed such that substantially all of its salts of cyclohexylsulphamic acid will dissolve in water in preference to the organic solvent. The addition of the complex of sulphur trioxide and triorganophosphorus compound to the cyclohexylamine may be carried out in the presence of a tertiary organic base which is stronger than cyclohexylamine but not as strong as that to be added to or incorporated in the aqueous phase. The examples describe the preparation of the sodium salt.

Abstract: 1296484 Magnetic coin eliminator MARS Inc 20 March 1970 [20 March 1969] 13739/70 Heading G4V A coin 18, travelling along the coin passageway 12 and supported by the platform 16, enters the field of a magnet 52, situated in an aperture 20 of the passageway wall 15, which is movable between positions adjacent and spaced from the platform, the field strength of the magnet being sufficient, for coins within a predetermined range of permeability to density, to effect lateral movement of a coin while it is supported from the platform, but insufficient in the second position to support the coin which is now free of the platform so allowing it to fall from the eliminator. The coin is preferably brought to rest adjacent the magnet by a soleno id controlled arrestor pin 19. In a first embodiment (Fig. 1, not shown) the magnet is a permanent magnet, in the embodiment shown it is an electromagnet, having a magnet coil 53. The magnet is preferably supported on a pivoted arm 54 which is connected to the armature 60 of a solenoid 58 that effects movement of the magnet. The magnet may be provided with a plate 56, e.g. of PTFE, which has a surface of low coefficient of friction, to facilitate the separation of the coin from the magnet. To ensure that coins of high permeability fall from the magnet when it is moved from the platform the strength of the magnet may be reduced in this position, preferably by the use of a soft iron shunt 62. The magnet may forcibly strike the shunt further ensuring that the coin is released. The solenoid 58 is actuated after the retraction of the arrestor pin 19 by suitable control circuitry 35 which includes a coin sensor and timing device. A coin with a low permeability to density ratio therefore continues rolling down the passageway before the magnet is moved.

Abstract: 1324241 Electric selective signalling O R FRISCH and G S B STREET 16 Oct 1970 [24 Oct 1969] 52283/69 Heading G4H [Also in Divisions B6 and G1] In apparatus for tracing out a desired pattern on a recording medium using a light beam, a pair of steering mirrors are controlled by servocontrol means in accordance with the difference between digital signals representing the actual and command positions and the intensity of the light beam is varied in dependence on the velocity of the tracing to compensate for differences in exposure of the recording medium to the light. The difference signal is also used to control a secondary deflection system for fine control of the beam. The apparatus may be used for etching on metal film using a laser beam or for recording on photographic film. As described for each mirror a vector representing the required trace is fed in, in pulse train form, to a buffer store 24 and read out at a rate corresponding to the required speed of trace to gates 26, 27, one of which is enabled depending on the required direction of the trace. The gates 26, 27 are connected to further gates 30, 29 which receive on their other inputs feedback signals from a counter detecting fringes as the mirror steering the beam is moved. These pulses are phase delayed with respect to the pulses from the buffer store. An error sealer 36 receiving the gate outputs energizes the driving circuit 37 for the mirror in one of two directions the speed of drive being determined by the difference between the required velocity and the actual velocity. The light beam which is fed via the mirror system (12, Fig. 1, not shown) to the recording medium (11) is modulated by intensity control (17) in accordance with the required density of trace and the actual velocity of trace. The scaler 36 also supplies the error signal to the secondary deflection control circuit. The secondary system may be as in Specification 1,012,430.
