Title: Automatic circuit interrupter
IPC: H01H71/52
Filed: 1968-03-18
Abstract: 1,222,428. Automatic circuit-breakers. MITSUBISHI DENKI K.K. 18 March, 1968 [16 March, 1967], No. 12899/68. Heading HlN. The moving contact arm 34 of a small circuitbreaker is coupled to a switching handle 50 by toggle links 42, 46 which are restrained in the substantially aligned position shown in Fig. 2 by a link 92 coupled by a pin 88 to a latch 84 which is pivoted at 86 on a stationary supporting plate 28. A spring 94 tends to turn contact arm 34 clockwise about its pivot 32 while springs 56 and 90 tend respectively to turn handle 50 and latch 84 in the clockwise direction, spring 94 being effectively stronger than spring 50 which in turn is stronger than spring 90. Overcurrent in coil 64 pivots armature 70 about pin 72 and an upstanding portion engages a tripping plate 82 mounted on a bell-crank member 76 to pivot the latter and lift a pin 78 thereon clear of the nose of latch 84 allowing spring 94 to collapse toggle 42, 46 with its apex away from latch 84 and to open contacts 36, 24 (as in Fig. 3, not shown). The springs 56 and 90 then co-operate to straighten the toggle 42, 46 and return latch 84 to be retained by pin 78, the armature 70 having been restored by a spring 74 upon the circuit interruption. Movement of handle 50 in an anti-clockwise direction from this tripped condition (Fig. 4, not shown) exerts a thrust on the toggle 42, 46, which is maintained by link 92 in a substantially aligned condition, and recloses contacts 36, 24 as in Fig. 2. The link 92 may be pivotally connected to the toggle link 46 instead of to the junction pin 48 (Fig. 6, not shown), or the latch 84 may be arranged to turn in the reverse direction by pivoting its central portion on pin 86 and coupling link 92 to its lower extremity (Fig. 7, not shown).

Title: Improvements in or relating to means for measuring or detecting x-rays or the like radiation
IPC: G01T1/185
Filed: 1946-05-01
Abstract: 615,562. X-Ray measurements. GENERAL ELECTRIC CO., Ltd., DUNHAM, C. R., and MICHAELIS, W. M. May 1, 1946, No. 13158. [Class 37] [Also in Group XX] Means for measuring or detecting X-rays or like radiation comprises an ionisation chamber having a pair of electrodes and means to produce an alternating or pulsating ionisation current within the chamber, the amplitude of the current being dependent on the intensity of the radiation falling on the chamber. As shown, the ionisation chamber comprises an outer electrode 4 of e.g. graphite closed by an amber plug 5 supporting an inner electrode 3 and coated with metal 6 to contact the electrode 4. A constant D.C. potential is applied to the electrodes through leads 7, 8 from a cable 9. A steel cylinder 2 mounted to rotate on a ball bearing 13 on the amber plug 5 is rotated by air from a nozzle 15 impinging on a turbine wheel 14 mounted on the cylinder. Radiation passes through diametrically opposite windows 16, 17 each extending over a 90 degrees sector of the cylinder 2. The periodical exposure of the chamber to radiation produces a pulsating ionisation current, the A.C. components of which are readily amplified and measured. Alternatively, the apertured wall may be stationary and have a shutter, which may, according to the Provisional Specification, be a cylinder with part of its surface cut away, rotating round the wall. An A.C. ionisation current may be produced by applying an alternating potential to the electrodes of an ionisation chamber. Two chambers may form opposite arms of an A.C. bridge network, the other two arms being formed by similar chambers shielded from or out of the field of the radiation, or evacuated, or by condensers having the same capacity as the chambers. The change in bridge current is measured and the bridge may be balanced initially to give zero current for zero radiation.

Title: Improvements in thermal relays
IPC: H01H71/16
Filed: 1921-05-11
Abstract: 164,317. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Miller, F. H.). June 3, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermal switches, cut-outs, and interrupters.- Thermally operated electric relays consist of two metal members mechanically secured together but thermally insulated from one another, one of the members being adapted in operation to be heated to a higher temperature than the other. In the form shown in Fig. 1, the relay 4 consists of a bimetallic member 13 comprising a metal strip 14 of low coefficient of expansion and a strip 15 of higher coefficient of expansion, insulated rivets 24 securing the strips 14, 15 together mechanically. An interposed insulating strip 16 acts as a thermal and electrical insulant between the strips 14, 15. The lower strip 15 carries the current supplied to the machine 1, and, when the strip is deflected owing to the passage of abnormal current through the strip 15, contact is broken between an extension 17 of the strip 15 and a contact stud 18, thereby de-energizing the holding-on coil 5 and allowing the circuit-breaker 3 to disconnect the supply circuit 2. In the modification shown in Fig. 2, the bimetallic bar consists of two thermally-insulated metal strips 14, 15, which are electrically connected at one end so that the current traverses them in series. In the form shown in Fig. 3, the strip 15 having the greater co-efficient of expansion is heat-lagged by heat-insulating material 27, to increase its temperature, the current passing through both strips. in series. In the form shown in Fig. 4, the bimetallic bars, consisting of strips 14, 15 with interposed insulating material 16, is surrounded by a number of magnetizable bands 25, the induced hysteresis losses in which serve to increase the temperature of the bar. In the form shown in Fig. 5, the current carrying element 15 is slotted, as shown in Fig. 6, its increased resistance augmenting the heating effect of the current. In the form shown in Fig. 8, the member 14 of lower coefficient of expansion is provided with heat-radiating pins 26, thereby augmenting any difference of temperature between it and the current-carrying element 15.
