Title: Electric circuit breakers
IPC: H01H33/14
Filed: 1970-11-13
Abstract: 1315026 Circuit breaker YORKSHIRE SWITCHGEAR & ENG CO Ltd 13 Oct 1971 [13 Nov 1970] 54152/70 Heading H1N A fluid immersed circuit breaker comprises a movable bridging contact 1 carried by an insulating carrier 2 and having two sets of movable main 8, 9 and arcing contacts 17, 18 which cooperate respectively with the main and arcing contacts of a pair of fixed contacts, the movable arcing contacts 17, 18 being disposed in an arc quenching chamber 29 having a restricted outlet 32, 33 positioned so that under pressure of gas generated by arcing in the chamber a stream of fluid under pressure is directed across the arcing path of at least one pair of fixed and movable arcing contacts, and one or more of the arcing paths being surrounded by at least one closed loop of ferromagnetic material. As shown the loop of ferromagnetic material is constituted by steel plates 21, 22 and joining bolts 23 to 27. Both sets of arcing contacts have ferromagnetic loops as shown which are joined by a ferromagnetic plate 34. The loops have eddy currents induced therein by arcing and thereby produce complex magnetic fields surrounding the arc paths which constrict the arcs towards the minimum paths and cause a rapid oscillatory disturbance of the arcs thereby producing oil and gas turbulence which renders the arcs unstable. The bolts 23-27 and ferromagnetic plates 21, 22 improve the bursting strength of the bridging contact assembly.

Patent GB-1323712-A (GB)
Title: Electrical networks
IPC: H03B7/06
Filed: 1970-01-02
Abstract: 1323712 Negative impedance circuits POST OFFICE 9 Dec 1970 [2 Jan 1970] 56699/72 Heading H3T A negative impedance circuit comprises a bipolar transistor T3 the bias for which is provided by a circuit including a field effect transistor T4 connected between the base and emitter of transistor T3. For small values of current I 2 , transistor T3 is turned off, and all current flows through the path R3, T4, R4. As I 2  increases the source-drain resistance of T4 increases and T3 turns on. The current through R3 then decreases with increasing I 2  and since most of voltage V2 is made up of the voltage drop across R3, the characteristic of the circuit shows a negative dynamic resistance region.

Title: Method of and apparatus for checking the form of a concave surface
IPC: G01B5/20
Filed: 1969-07-22
Abstract: 1331931 Testing surface shape JOSEPH LUCAS (INDUSTRIES) Ltd 13 Oct 1970 [22 July 1969] 36802/69 Heading G1M An apparatus for testing the shape of a concave surface comprises a ball ended member 20, a mounting 35 for holding a test piece, a device 23 sensitive to linear displacement extending within the member so as to be engageable in use with a point on the concave surface, means for rotating the mounting about an axis thereof and means for rotating this axis about an axis of the said ball. As described a piston slipper under test is placed in cup 35 of plunger assembly 32. Spring 36 urges the piston slipper into making contact with ball 21 and into contact with the end of plunger 23 of a probe 75 sensitive to axial displacement of the plunger. The output of probe 75 is displayed on a recorder 76. Switch 62 is closed, then switch 61 is pressed to operate the motor to rotate shaft 39 and thus via gear train 40, 29, 30, 31, 34 to rotate the slipper to a desired position, when switch 61 is released. Plunger 52 is pushed in against spring 54 and turned so that peg 55 engages a step in recess 56 to retain the plunger. This action causes the plunger to move member 49 transversely to the axis of sleeve 24, and shaft 39, engaging wedgeshaped member 48, moving it axially of shafts 24, 39 and sliding clutch member 43 on splines 44 against the force of spring 45 into contact with a second clutch member 42. Sleeve 24 and shaft 39 then rotate together and the slipper rotates about the axis of spindle 33 and the axis of sleeve 24 and 39. After a predetermined degree of rotation of shaft 24, the end of a recess 47 in collar 46 engages the peg 55 to disengage it from the step in recess 56, when the plunger moves outwardly under the influence of spring 54 and switches off via switch 77 the motor and via switch 59 the recorder 76. If the surface of the slipper corresponds exactly to the wating end of ball 21 the trace on recorder 76 will be a straight line. For other forms of mating surface, the trace will be characteristic of the surface, to be compared against a reference standard.

The web member provides, alternately, surfaces 18 forming part of a frustum of one pyramid, and surfaces 19 forming part of a frustum of another pyramid. The two pyramids are symmetrically disposed, and point in opposite directions relative to the axis of the wheel disc. Planar portions 20 lying in axial planes of the wheel disc interconnect surfaces 18 and 19. The wheel disc may be manufactured by casting the disc from a mould in which ridges forming said angles of the web leading towards the lugs have been relieved along their length to form the thickened portions from the hub towards the lugs. Said thickened portions 11 act as feeders for the metal to the lugs 7 when the wheel-disc is cast.
