IPC: E03D1/33
Filed: 1916-11-27
Abstract: 112,961. Muntz, W. E. Nov. 27, 1916. Ball and float valves.-A float-operated trip or release-catch mechanism for releasing a mechanical movement or arrangement, such as weights for operating valves, comprises a flat thin float q connected by a chain p or other flexible or jointed connexion to a weighted release lever k. In the example shown in Fig. 1 as applied to flushing- cisterns a, the release lever is provided with a catch-member m which engages a notch in the spindle of a supply valve e to hold this valve in its closed position whilst the discharge valve f, interconnected by levers and a rod g, h, i, to the supply valve e, is kept open to allow the contents of the cistern a to pass away for flushing. The operating-chain i<1>, when pulled by hand, moves the valves and release-mechanism to the positions shown. When the water has left the float q, the weight of the float, acting through the chain &c. p, releases the catch m and allows the counterbalance weight j to open the supply valve e and to close the discharge valve f. As applied to a safe or strong room fastening or lock, a float reservoir is attached to the inside of the door and a catch m on the lever k arranged to engage a ratchet or rack on the top edge of the bolt of the lock so as to allow the bolt to be moved for locking, but prevent its return from unlocking. A number of pin holes are formed in the bottom of the float reservoir, however, so that during the night, or in a predetermined time, the water runs away so as to leave the float q free to release the catch m and allow the lock bolt to be drawn back to open the safe or strong room.

Title: Arrangement for automatic tuning of radio receivers or the like
IPC: H03J7/04
Filed: 1937-06-19
Abstract: 474,967. Wireless receiving circuits. COLE, Ltd., E. K. June 19, 1937, No. 17126. Convention date, Sept. 1, 1936. [Class 40 (v)] In a radio receiver of the kind having automatic frequency control, the tendency of the receiver tuning to pull-in to the frequency of a powerful station adjacent in frequency to that of a desired weaker station is prevented by limiting the automatic frequency control voltage within predetermined limits. By this means the control voltage, which normally varies in amplitude with the signal strength of the station received, is maintained approximately constant. The Figure shows a known automatic tuning arrangement in which the frequency of the tuned circuit 9, 10 of the local oscillator 4 of a superheterodyne receiver is controlled by a thermionic reactance 11 deriving its control voltage from the usual type of two-circuit error-detector 14 ... 20. According to the invention, a limiter circuit comprising a pair of reverse-coupled diodes 22, 23, negatively biassed by batteries 24, 25, is connected in parallel with the control voltage supply to the reactance 11. Thus, when the control voltage on either side of the true I.F. exceeds the voltage of 24, 25 respectively, the diode 22 or 23 becomes operative to limit the voltage applied to valve 11. In a modification, Fig. 4 (not shown), the sources 24 25 are replaced by resistances traversed by rectified current derived from the oscillator circuit 10 through a coupling coil, rectifier and resistancecapacity filter. By this means the bias voltage on the limiters is made to vary with frequency to compensate for the variation with frequency of the effect of the automatic frequency control system.
