Title: Temperature regulating apparatus
IPC: G05D23/275
Filed: 1928-10-29
Abstract: 299,714. Weill, L. D. Oct. 28, 1927, [Convention date]. Controlling consuming devices; regulation, automatic.-Maximum temperature is regulated by means which interrupts or modifies the source of heat, &c., at a predetermined limit, and additional means are provided to maintain the interruption for a determinable period. In the application to an electric furnace a, heating resistances b<1>, b<2> are supplied with biphase current, and a heat-sensitive device d is provided, connected by a circuit f to an electromagnet e. When the electromagnet e is de-energized, its armature h opens the circuit j of another electromagnet l, the armature m of which controls the circuit n of an electromagnetic switch i, o, which is adapted to make or break the circuits of the heaters b', b<2> to interrupt or reduce the heating. The device which maintains the interruption for a determinable period is associated with the relay l, and includes a clock movement p. The contact n<1> is carried by a lever m' operated through a pawl m<2> by the lever m. A catch m<3> is also adapted to engage with a pawl p<1>, and both levers are provided with counterweights tending to lift them. A signal lamp r may be provided, either in the circuit f or in a shunt s from circuit c, the circuit s being opened or closed by the armature h at the same time as the circuit j. The device d is set at the predetermined temperature, and the device p is set to release the pawl p<1> after a predetermined interval, say 40 seconds after its engagement. When the temperature reaches the required point, the relay e is energized, and consequently the relay l and lamp r. Relay l closes the switch n' of the circuit o and thus opens the switch i controlling the heaters. If it is found that the clockwork p releases the lever m<1> while. the lamp r is still lighted, the interruption of the heaters has been insufficient, and the period is adjusted by regulator p<2> until the lamp r is extinguished shortly before the lever m<1> is released. Conversely, if the lever m' is released to long after the lamp r is extinguished, the regulator p<2> is adjusted accordingly. On release of the lever m<1>, the relay is again operative to switch off the current at the predetermined temperature, and the sequence of operations is repeated. The electric current or other regulable quantity may not be completely interrupted but merely reduced. According to the Specification as open to inspection under Sect. 91 (3) (a), the apparatus may be employed to regulate automatically the minimum value of a physical variable, or two similar sets of apparatus may be employed to regulate maximum and minimum. The regulation of E.M.F., electric current, and power may also be effected. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to electric frequency conversion systems and apparatus
IPC: H02M5/32
Filed: 1945-11-22
Abstract: 604,059. Converting electric currents. BRITISH THOMSON-HOUSTON CO., Ltd., GIBBS, W. J., and WALKER, J. H. Nov. 22, 1945, No. 31518. [Class 38 (ii)] A method of changing low frequency A.C. to a higher frequency consists in passing the current from the low frequency source through saturable chokes to cam-operated vibrating contacts which operate at such a speed that the resulting phase wave of each phase will have a frequency which is a multiple of the supply frequency. In an example each of the three-phase lines I-III is connected through a saturable choke 4 and protective choke 5 to contacts associated with a pair of vibrators indicated respectively at 7 and 8, 9 and 10, and 11, 12, the cam operation being arranged so that contacts 7, 11 are closed while the others are open, and the opening of 7, 11 is accompanied by the closing of 8, 10, the closing of 9 and 12 being simultaneous with the opening of 8, 10. The resulting single phase current of a frequency three times that applied at terminals I-III is supplied to a load 13. Condensers 6 are shunted across the chokes 5 and vibrating contacts. The single phase wave form may be improved by any known means, e.g. filter circuits for the higher harmonics. In a modification, Fig. 3 (not shown) the load is divided into three more or less equal sections connected either in delta or star, and the three leads connected thereto are each connected over a single cam-operated vibrating contact and protective choke to a saturable choke connected to a supply lead, a condenser being shunted across each vibrating contact and associated protective choke. The cams may be operated by a synchronous motor supplied from the three-phase terminals, and adjustment of the phase angle obtained by mounting the stator rotatably in a cradle. Different frequency ratios may be obtained by the use of known forms of phase conversion, e.g. by converting the three phase supply to nine phase and increasing the number of pairs of contacts from three to nine the ratio of conversion is raised from 3/1 to 9/1.
