Abstract: 1,175,352. Removing hydrochlorites from alkali metal chlorate solutions. ELECTRIC REDUCTION CO. OF CANADA Ltd. 6 Jan., 1967 [8 Dec., 1965], No. 52157/65. Heading C1A. Alkali metal chlorates are produced by heating an aqueous solution containing hypochlorous acid and alkali metal hypochlorite at a temperature above 65‹ C. while maintaining the pH of the solution between 4À5 and 8À0. The preferred temperature range is 80-100‹ C. and the preferred pH range is 6À8-6À9. This process is particularly designed to reduce the hypochlorite level in an aqueous solution withdrawn from an electrolytic chlorate production cell and the hypochlorite content is preferably reduced to less than 0À2 gram per litre by this process. Further reduction may be accomplished, in the conventional manner, by adding urea, prior to recovery of sodium chlorate from the solution. The pH may be controlled by addition of an inorganic base, preferably an alkali metal hydroxide, especially one wherein the alkali metal cation is the same as that of the hypochlorite.

Patent GB-522922-A (GB)
Abstract: 522,922. Calculating-apparatus. WANDERER-WERKE, AKT.-GES. Dec. 21, 1938, No. 37149. Convention date, Dec. 21, 1937. [Class 106 (i)] A calculating-machine having a plurality of totalizers is provided with totalizer engaging members all of which are conditioned for operation, by coupling members actuated by an operating member of the machine, but only the coupling members for selected totalizers are maintained effective, during a machine cycle, by auxiliary power means which is controlled by the totalizer selection means. The invention is shown applied to a machine of the type described in Specification 444,033, wherein the totalizer selection means comprises electromagnets controlled by a bank of selection keys or, automatically, by contacts co-operating with rollers on the travelling paper carriage. The totalizers 51, Figs. 1 and 2, are guided in radial slots in the side plates 54, 56 of a supporting frame and are controlled for engaging movement with the differential actuating wheels 60 in the known manner by rocking arms 62, 63 which coact with rollers 66 on the axles 52. The arms 62, 63 are mounted on spring controlled spindles 64 and are formed with apertures through which pass coupling rods 74 adapted to be displaced longitudinally to engage apertures 254 in an operating plate 67, Figs. 1 and 5, rockable in timed relation with the actuator wheels 60 by means operatively connected to the main shaft of the machine in known manner. The coupling rods are aligned with the cores 70, 71 of electromagnets 11 the circuits of which can be comple:ed to effect the selection of the totalizers. The cores are formed of an iron member 70 and a member 71 of non-magnetic material, preferably aluminium. The lower ends of the cores rest on a disc 100 provided with cam blocks 101 one for each core, the disc being supported on rollers 105.

Title: Variable reluctance motor having sine pulse controller
IPC: H02K29/00
Filed: 1971-11-18
Abstract: 1335935 Control of reluctance motors FORD MOTOR CO Ltd 18 Nov 1971 [8 March 1971] 53535/71 Heading H2J A variable reluctance motor generally similar to that described with reference to Fig. 1 of Specification 1,240,979 is controlled by the circuit shown, in which the or each winding 80 of the motor is energized from a D.C. source 92 by firing a silicon controlled rectifier 90, the consequent charging of a capacitor 82 (to a voltage greater than that of source 92) providing a further energizing pulse to the winding 80 when another silicon controlled rectifier 88 is fired to allow discharge of the capacitor therethrough. The rectifiers 88, 90 are controlled by a conventional rotor position senser (e.g. apertures sequentially aligned with light-activated silicon controlled rectifiers), so that each is fired at the start of a period of increasing motor permeance. The circuit reactances 80, 82, 94 are chosen so that an approximately sinusoidal pulse is produced having a period equal to the period of increasing magnetic permeance at the highest speed of operation of the. motor, the pulse shape and period being slightly variable with the motor speed. In a typical operation, Fig. 4 (not shown), the rectifiers 90, 88 are alternately fired at the start of successive periods of increasing permeance and the charge on the capacitor 82 builds up intil it reaches a steady state value providing maximum current to the motor winding. To reduce the current, the silicon controlled rectifier 98 is fired following a current pulse produced by firing the rectifier 90, thereby allowing the capacitor 82 to return energy to the source 92. Continued alternate firing of rectifiers 90, 98 reduces the current to zero when the capacitor voltage becomes equal and opposite to the source voltage. A further steady state voltage condition may be produced by repetition of a sequence in which the rectifier 90 is fired first, the rectifier 98 second and the rectifier 88 last. Further current variation may be obtained by changing between the three methods of control described above, each lasting for desired respective intervals of time. Other methods of control are Multiple pulsing operation.-At low motor speeds, when the pulse period is a small fraction of the period of increasing permeance, a plurality of pulses may be supplied during each increasing permeance period, Fig. 5 (not shown), by the use of one or more of the three methods of control described above. Pulse skipping operation.-At high motor speeds pulses are only supplied during certain of the periods of increasing permeance, Fig. 6 (not shown). Pulse shifting torque control.-The pulse is shifted partially out of the period of increasing permeance into a period of constant permeance, Fig. 2 (not shown), thus reducing the torque for the same current. The controlled rectifiers may be replaced by triacs or transistors, logic circuitry providing the firing signals in each case.
