Title: Improvements in or relating to electric fusible cutouts
IPC: H01H85/36
Filed: 1937-10-12
Abstract: 502,501. Electric cut-outs. GENERAL ELECTRIC CO., Ltd., and GIBSON, J. W. Oct. 12, 1937, No. 27758. [Class 38 (i)] In a fusible cut-out of the kind in which, when fusion occurs, the opening of the circuit is accelerated by a spring or springs, the strain is taken by a strain wire of conducting material - electrically connected to only one terminal of the cut-out, which wire is itself fused by an arc formed between the strain wire and an arcing horn when the fuse element fuses. The terminal 5 is secured to one end of a container by a spring 6 and is held in position against the tension of the spring by a strain wire 9 secured at its ends to insulating blocks 10 on an annular terminal 8. The fuse element 11 is secured at its mid-point to the terminal 5 and at its ends to arcing horns 12 secured to the terminal 8. When the fuse element fuses, arcs form between the strain wire and the arcing horns so that the wire fuses and the terminal 5 which normally projects above the surface of the insulating liquid 7 is immersed to extinguish the arc. In a modification, a liquid director or piston is secured to the terminal 5 so that when the strain wire fuses and the terminal is immersed, a stream of liquid is directed towards the arc.

Abstract: 1455748 Piezoelectric positioning systems MOSKOV INST ELEKTRONNOI TEKHNIKI 26 June 1974 [26 June 1973] 28440/74 Heading H2A A piezoelectric positioning system allows a table 1 and object 2 to be moved along "X" and "Y" axes, and/or rotated about the "Z" axis, as desired. In the arrangement shown, a pair of bimorph piezoceramic plates 3, 4 have lower ends rigidly fixed in a cruciform platform 5, and have upper ends joined to the table 1 by way of lamina springs 6, 7 set perpendicular to the plates 3, 4, the springs being rigidly joined to the table at their upper ends but being pivotally connected to the plates by way of couplings 8, 9. A further pair of bimorph plates 10, 11, perpendicular to plates 3, 4, are joined to table 1 via further springs 12, 13 pivoting at 14, 15. When therefore a P.D. is applied to plates 3, 4 (terminals &c., not shown), they deflect to cause springs 6, 7 to push table 1 in the X-direction, the springs 6, 7 being unable to bend in their own planes but the springs 12, 13 being able to bend easily in directions perpendicular to their planes. Application of a P.D. to the plates 10, 11 causes a corresponding movement in the Y- direction. Rotation about the Z-axis is produced by applying a P.D. across a further bimorph piezoceramic plate 16 held rigidly at its periphery in a ring shaped base member 17, the deflection at the centre of the plate causing a pusher member 18 and a pair of rollers 19 to interact with a two-start helical face cam 21 to rotate the platform 5 and table 1, the member 18 and the cam 21 constituting a screw pair coupling.

Patent GB-372686-A (GB)
Title: Improvements in and connected with variable speed gear
IPC: F16H29/04
Filed: 1931-10-16
Abstract: 372,686. Variable-speed gearing. JONES, E. W., Avenue Mount, Yarborough Road, Lincoln. Oct. 16, 1931, No. 28853. [Classes 80 (i) and 80 (ii).] Variable-speed ratchet gearing suitable for motor-vehicles comprises a combined crosshead and rack 10 which drives one-way mounted pinions 17 and is reciprocated from a variablethrow driving crank 8. The crank 8 reciprocates laterally in guides 9<1> in the crosshead 10 which itself reciprocates in slides 10<1> in a revoluble guide member 14 which is held fast for geared drives and is clutched to a driving flywheel 1 for a solid high-speed drive. In the geared configuration shown in Fig. 1, the guide 14 is held against rotation by a cone engagement with a casing 12 at 12<1>, being held thrust to the left by a cam 106 acting on a bell crank 108. An automatic speed variation results from a balance between the outward thrust on the crank 8 from a spring 125 acting through a bell crank 2 and the inward thrust of the load reaction. Manual control is imposed against the spring by a pedal 18 which acts on a sliding sleeve 5 through which passes a transverse pin 4 engaging the bell crank 2. At the upper limit of the automatic drive, the crank 8 is at its maximum throw. When the speed of a driven shaft 111 approximates that of the driving-shaft 126, the leftward displacement of the sleeve 5 through a link 102 trips the cam 106 so that a spring 21 is freed and thrusts the guide and clutch 14 to the right into clutch engagement at 11a with the flywheel 1, the parts turning solid. If now the engine slows down, pressure on the pedal 18 disengages the clutch 11a, and by replacing the cam 106 reinstates the automatic geared drive. A modified construction is described in which the cone surfaces at 121 to prevent backward motion are replaced by a pawl which overruns on the solid drive. The pinions 17 each engaged by a rack on the crosshead 10 have sloping teeth the reaction at which serves to move the pinions axially into and out of engagement with radial ratchet teeth 17<2>, 17<3> rigid with the one-way driven shaft 111. A hand-lever 19 which slides an internal gear 21a on long splines 20a on the tail shaft 24 is shown in the forward drive position with clutch splines 20 engaged. When the lever 19 is moved to position 19a, the clutch splines 20 are disengaged. Although the gear 21a engages a pinion 22, this is the neutral position. On further movement of the lever 19 to position 19b, a rim 123 on the gear 21a strikes the end of a countershaft 200 so as to carry a wheel 23 into mesh with a pinion 23a. A reversed drive between the shafts 111, 24 takes place through train 23a, 23, 22, 21a, 20a. An arrangement is described in which the pinion 22 is separately movable into mesh with a spur wheel on the boss of the gear 21a. This engagement is to cause the engine to be driven at increased speed through the countershaft 200 when the engine is to be used for braking a vehicle.
