Title: Improvements in or relating to control means for electric switches
Inventor: CLIVES STANLEY WILLIAM
IPC: H01H9/28
Filed: 1958-06-27
Abstract: 879,511. Oil-break switches; electricallytripped switches; switchgear structures; locking switches; switch covers. GENERAL ELECTRIC CO. Ltd. May 19, 1959 [June 27, 1958], No. 20675/58. Class 38 (5). An oil circuit-breaker similar to that described in Specification 879,515 is fitted with control means 24 comprising a depressable and rotatable cylindrical button 25 having segmental grooves 27, 28, 29 engageable by a gate 30 which can be padlocked at 31 to prevent operation of the button 25 when set in position, as for example, in the " locked-off " position Fig. 3, when the breaker is closed and earthed. Normally the button 25 is rotated 90 degrees from this position with the gate 30 riding on its cylindrical surface, and depression of the button against a spring force causes its end 32 to engage an arm 33 which rotates a bar 13, disengages arm 14 and so trips the breaker. Rotation of the button 25 through 90 degrees while in the depressed position causes the gate 30 to engage groove 28 and the button may then be locked in this position to prevent closure of the breaker. A rotation of 90 degrees from the "locked-off" position in a direction opposite to normal causes gate 30 to engage groove 29 and a leaf spring 34 carried by end 32 to engage arm 33, thus preventing rotation of the bar 13 and tripping of the breaker. This position may be used during the " starting-up " period of a motor controlled by the breaker, to restrain the action of an overcurrent relay, Fig. 2 (not shown), unless a fault occurs, in which case the relay plunger engages a flange 12 to overcome the force of spring 34 and so trip the breaker. After starting, the button 25 is returned to its normal position by spring action. Specifications 879,512 and 879,513 also are referred to.

Title: Manufacture of zinc sulphide pigment
IPC: C01G9/08
Filed: 1934-07-16
Abstract: In precipitating zinc sulphide from a zinc salt solution, the salt solution is brought into contact with hydrogen sulphide gas in an eductor with recirculation of the resulting slurry in contact with hydrogen sulphide gas through a second eductor, and the settling rate of the crude zinc sulphide slurry is regulated by controlling the following factors: (1) concentration of the hydrogen sulphide gas brought into contact with fresh zinc salt solution in the first eductor, (2) temperature of the precipitating mixture within the eductors, (3) ratio of gas volume to liquor volume within the eductors, and (4) the ratio of the p  amount of slurry recirculated to the amount of zinc salt solution freshly introduced.  Preferably the settling rate is such that when 500 c.c. of the slurry are left standing for 10 min. in a cylindrical tube of about 1\ba7/8\bein. diameter, the crude zinc sulphide precipitate settles so as to yield between 30 and 90 c.c. and preferably between 30 and 60 c.c. of clear supernatant liquor. When carrying out the process in a series of tanks, for instance in the manner described in Specification 435,287, the concentration of hydrogen sulphide in the gas contacting with fresh zinc salt solution may be at least 50 per cent, the precipitation be effected at about room temperature, the ratio of gas volume to liquor volume be between 25 and 50 to 1, and the ratio of volume of slurry recirculated to the volume of slurry forwarded be about 4 to 1.
