Title: Improvements relating to hand operating mechanism for electric switchgear
IPC: H01H3/06
Filed: 1950-11-30
Abstract: 704,613. Actuating heavy-current switches. SWITCHGEAR & EQUIPMENT, Ltd., and SHARPLES, F. A. Nov. 28, 1951 [Nov. 30, 1950], No. 29363/50. Class 38(5) [Also in Group XXIV] In a manual operating mechanism, particularly for a large outdoor polemounted switch, the operating force is transmitted from an operating handle 25 to the moving contact (not shown) through two levers 17, 23 pivoted about spaced parallel axes 18, 24 and connected by a pivot 21 capable of sliding along one of the levers, which are arranged so that their mechanical advantage is at its greatest when the movable contact of the switch is on the point of breaking away from the fixed contact. In the Figures, the lever 23 carries the handle 25 and is slotted at 22 to slidably receive the pivot pin 21 which is carried by the lever 17, the latter being a bell-crank lever with its shorter arm 16 pivoted to a connecting rod 15 which is pivoted to a universal joint 12 interconnecting a switch operating rod 11 and a guide rod 13. Fig. 1 shows the position occupied by the mechanism when the switch is closed and on opening the switch, the initial movement of the lever 23 to the position shown in Fig. 3 is effective to take up any lost motion in the linkage, so that the switch contacts are about to separate. In this position the lever 23 is in line with the fixed pivots 18, 24 so that the pin 21 has moved along the slot into its nearest position to the fixed pivot 24, the greatest mechanical advantage of the levers being obtained. Thereafter the mechanical advantage decreases as the pin 21 moves along the slot 22 as the lever 23 is moved to complete the opening movement of the movable contact. Members 26 are provided to permit the locking of the lever 23 when the switch is fully closed or fully open.

Filed: 1970-06-17
Abstract: 1313351 Measuring corrosion rate PETROLITE CORP 17 June 1970 [13 Aug 1969] 29481/70 Heading G1N In an electro-chemical corrosion rate meter having three identical electrodes in which the current between a first pair of the electrodes to produce a predetermined polarization voltage between a second pair of the electrodes is measured, the current is derived from a differential amplifier one input of which is fed with the voltage between said second pair of electrodes and the other is fed with an exponentially varying voltage, the time constant of which is adjustable to be equal to that of the capacitive-resistive load of said second pair of electrodes, whereby the current between said first pair of electrodes is substantially from the moment of switching on despite the R.C. characteristic of the electrodes.  As shown in Fig.4, test, reference and auxiliary electrodes are connected to terminals T, R and A respectively, their electrical equivalents being shown in box 33. With switch 44 in its "null" position, source 43 charges capacitor C2 to reference voltage VR, and a source of nulling voltage is adjusted to give a zero reading on meter 46. Switch 44 is then changed to its "operate" position, capacitor C2 discharges exponentially through R2 whereby an exponentially varying voltage is applied to input 41 of the differential amplifier 36. The output of amplifier 36 is fed through ammeter 38 and between the auxiliary and test electrodes, the voltage between the reference and test electrodes (which varies exponentially with a time constant R1. C1) being applied to input 39 of amplifier 36. R2 is adjusted by trial and error from an initial value which is too large (R2. C2  R1. C2) until the reading on ammeter 38 is constant from the moment of switching on, under which conditions, the current so indicated is indicative of the corrosion rate. The polarization time constant gives information about the thickness and composition of the polarization film on the test electrode.  In another arrangement, Fig.6 (not shown) the RC circuit (81) for applying the exponential voltage is arranged to be able to supply positive or negative voltages to the amplifier so that cathodic and anodic measurements may be made. A range change switch (72) is provided and a selector switch (71) for the different stages of the measurement procedure includes a position (V o ) for measuring the freely corroding potential.
