Abstract: 945,220. Solution mining of minerals. PITTSBURG PLATE GLASS CO. May 21, 1962 [May 26, 1961], No. 19430/62. Heading E1F. Solution mining of potassium chloride is carried out by drilling at least one borehole down to and through the potassium chloride deposit, feeding water or a potassium chlorideunsaturated solution down to the underside of the deposit to dissolve out a cavity there under, and then gradually allowing the level of the roof of the cavity to be raised by drawing out brine from the cavity as the potassium chloride deposit dissolves into a solution. Roof control of the cavity being formed is obtained by pumping down to the cavity a water immiscible inert fluid that will separate out above the water and brine in the cavity to form a layer sealing of the cavity roof from the dissolving action of the water. U.S.A. Specifications 2,161,800 and 2,331,890 are referred to.

Title: Improvements in locks
IPC: E05B65/00
Filed: 1948-07-20
Abstract: 652,904. Bolts; multiple fastenings. JENKINS, G. M. O. July 20, 1948, No. 19442. [Class 44] A lock for the doors of safes and strongrooms comprises at least one bolt or like locking element operable by a rotatable locking member, with a second member rotatable therewith by means of which the, or each, bolt is retained in its operative position irrespective of any subsequent movement of the locking member, except upon release of externally controlled stop means engaging the second member. In the form shown, a pair of bolts 3 are biassed towards retracted position by springs 5, and their inner ends, extended through guides 6, cooperate with the opposite surfaces of a cam 7 on the handle shaft 8 extending through the door. A second cam 9 freely mounted on the shaft 8 has two opposite cam surfaces 9a adapted to engage the inner ends of the bolts and maintain them in shot position. Cams 7 and 9 are held in frictional contact by means of a spring washer 10, Fig. 4, on the inner end of the shaft 8. To hold cam 9 against rotation, it is formed with two other surfaces 9b, either of which may engage with a vertical spigot 11. Fig. 2, attached to the armature plate 12 of an electromagnet 13, so that as cam 9 rotates in one direction spigot 11 is depressed until the cam reaches the position for holding the bolts shot, when it is forced upwards by a spring (not shown), bearing on the armature, and bears against the step 9c of the cam, thus preventing return movement. Further movement of cam 9 in the same direction is. prevented by shoulders 9d bearing against the inner ends of the bolts. Withdrawal of the spigot 11 to release cam 9 is effected by energizing the electromagnet, either by means of a key-operated switch or of a permutation device such as that described in Specification 651,987. Energization of the magnet also operates one of a pair of contacts, the other of which is operated by movement of the cam 7 through a push rod 15. The contacts are electrically connected so that if the handle is turned when the magnet is not energized an alarm circuit is operated. The electromagnetic control may be replaced by direct mechanical control.

Abstract: 1,271,885. Transistor switching circuits. BORG-WARNER CORP. 23 April, 1970 [14 May, 1969], No. 19616/70. Heading H3T. [Also in Division H2] A motor overload indicating signal is applied to an operational amplifier 36 which has a feedback circuit 40, 98, 41, 42 to provide proportional-plus-integral operation in the response of the output signal to a given change in the resultant signal. The amplifier output is applied through a diode 43 and conductor 26 to a transistor 27 to disable the firing circuit immediately in response to a sudden motor overload exceeding a predetermined level, or with a time delay in response to an overload less than that level. The amplifier output also renders a transistor 77 conductive to energize a protective relay 90 having additional contacts 92, 93 for rapidly resetting the feedback capacitors. A positive feedback path through a diode 73 becomes effective as soon as the amplifier output goes negative, disabling the negative feedback path via 40 and providing a rapid switching action. Capacitor 76 prevents operation by undesired transients.
