Title: A process for the manufacture of co-polymerisation products of homogeneous composition
IPC: C08F2/00
Filed: 1945-12-31
Abstract: Homogeneous copolymers of two or more substances with different rates of polymerization are produced by adding during the polymerization all the monomeric constituents so that their proportion during polymerization is kept constant, and if monomer concentrations lying within the "critical area" are employed, the absolute monomer concentrations are also kept constant.  The "critical area" of concentration is that in which the absolute concentration has a great effect on the properties of the polymer and ranges from zero to between 5 and 7 per cent by weight in emulsion polymerization and to approximately 15 per cent in solvent polymerization.  The addition of fresh monomers may be continuous or intermittent.  The process is applicable to the copolymerization of vinyl chloride and vinylidene chloride and the examples describe its application also to emulsion polymerization of (1) vinyl chloride and methyl methacrylate and (2) vinylidene chloride and methyl acrylate.  Specification 593,292 is referred to.

Title: Electrical sensing apparatus for particle-analyzing device
IPC: G01R27/26
Filed: 1974-08-12
Abstract: 1476209 Particle analysis systems COULTER ELECTRONICS Ltd 12 Aug 1974 [13 Aug 1973] 35413/74 Heading G1N The Specification discloses arrangements for compensating for:-(i) variations in the aperture size, and (ii) variations in the electrolyte conductivity in Coulter-type particle analyzers. Embodiments are described using both voltage pick-off and low impedance current pulse detector circuits, and pseudo-equivalent circuits are described. APERTURE SIZE COMPENSATION Fig. 11, signal current pulses are detected by low impedance amplifier 124 connected in series with the power supply source connected to the outer electrodes 101, 104. The "quiescent" aperture current is detected by the voltage-drop, picked off by electrodes 102, 103, and compared with a reference, 120. The difference, error, signal is applied via amplifier 106 to a chopper/invertor 112 feeding the power supply 116. In a modification Fig. 13 (not shown) a signal voltage detector, picks-off from the inner electrodes (which also provide the supply control signal as before. ELECTROLYTE RESISTANCE COMPENSATION, (a) may be derived from the resistance measured between two further electrodes, or (b) obtained by the ratio of two measurements e.g. D.C. and A.C. resistance. In type (a) Fig. 16, a pulse-signal-voltage is picked off from the inner electrodes, which also provide the aperture-power supply-control-signal as described above with reference to Fig. 13 (not shown). In Fig. 16 the pulse output signal is applied to conductivity responsive electrodes 270, 271. The pulse is first used to modulate an oscillator 262 and then synchronously demodulated at 274 to avoid feedback/coupling with the aperture circuit. Alternatively Fig. 17 (not shown), the conductivity electrodes may be arranged in the electrolyte supply pipe, so that they can be isolated by a cock (286); the detector circuit may be transformer-coupled to the aperture Fig. 18 (not shown). In Fig. 18 the transformer primary forms part of a series resonant circuit including the aperture. Type (b) RATIO CIRCUITS. In Fig. 19 the aperture is energized from D.C. source 401, and A.C. source 20 in parallel. The voltage output pulse from the sensor amplifier is applied to a series resonant filter 423, 424 leaving D.C. on the "X" line.The A.C. resistive component is picked off from the resonant filter by a phase-sensitive rectifier 426 and applied to the "Y" input of the divider 427 so that the electrolyte resistance component is cancelled in the output. Alternatively in Fig. 20 (not shown) a similar circuit is illustrated with a current pick-off. As this provides an inverse signal a multiplier is used instead of a divider.

Title: Improvements in control systems for induction motors of the capacitor type
IPC: H02P1/42
Filed: 1955-12-09
Abstract: 773,866. Control of A.C. motors. LEWUS, A J. Dec. 9, 1955, No. 35457/55. Class 38(3) A single-phase induction motor of the dual operating voltage type has a squirrel cage, rotor and main stator windings 12, 13, which are connected in parallel with each other, for low voltage operation, and in quadrature with an auxiliary stator winding 14. The windings 12, 13, are connected in series with the primary windings 19, 20, of a saturable transformer having a secondary winding 21 for supplying the auxiliary winding 14 through a capacitor 22. The primary winding sections are connected in parallel relation with respect to each other for low voltage operation. The starting current of the motor saturates the core of the transformer whereby peaked voltages are induced in the secondary winding and the auxiliary winding 14 takes a high current. The secondary circuit including the elements 14, 21, 22, is substantially series resonant during saturation of the transformer core so that the capacitor 22 effects substantial de-phasing of the starting current traversing the auxiliary winding 14 with respect to the primary current, so as to produce a high starting torque. As the motor accelerates the transformer core becomes unsaturated, the secondary voltage sinusoidal in character, and the current in the winding 14 is reduced. At the same time, the secondary circuit becomes well removed from series resonance. The saturation of the transformer core is maintained from standstill to at least half full-speed of the motor.. When the motor is cone nected to a high-voltage supply the primary circuit includes the windings 12, 13, 19, 20, in series relation, the secondary circuit remaining unchanged and its characteristics, being identical with those, for the low-voltage connection. The transformer may comprise a three-legged core member with an armature spaced therefrom by an air gap, the centre leg of the core carrying. the three windings 19, 20 and 21, Fig. 3 (not shown). A switching system may be provided having a single control member for changing-over the connections of the windings 12, 13, 19 and 20 to adapt the motor to the different values of the supply voltage, Fig. 4 (not shown).
