Abstract: 786,615. Linkwork. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 15, 1956, No. 8113/56. Class 80 (3). [Also in Group XXIX] A decoupling linkage for preventing the transmission of longitudinal movement from a member 1 to a member 3, particularly applicable to a manual and automatic fluid-pressure servomotor-control system of an aircraft (see Group XXIX), comprises a transversely disposed link 8 with a sleeve portion 5 for pivotal connection to a cylindrical member 4 on the member 1 and a slot 9 for engagement by pin 10 secured to the member 3. A spring 11 acts between a bracket 12 on the link 8 and the pin 10 to bias the latter into a position coaxial with the pivot member 4 when movement can be directly transmitted between members 1 and 3. The pin 10 is adapted to be moved along the link 8 against the spring 11 when desired by admitting a pressure fluid into a cylinder 15 carried by the link 8 to act on a piston 16 coupled to the pin 10. The pin 10 is thus moved out of alignment with the pivot 4 and no movement can be transmitted between member 1 and member 3 within the designed range. The pin 10 could be controlled by an electric solenoid, or an electric motor associated with a rack-and-pinion mechanism, instead of the hydraulic means. A pin 7 on the pivot member 4 operates in a slot 6 of the sleeve 5 to limit the relative angular movement thereof. In a modified arrangement the link 8 is of tubular form pivoted to a yoke on member 1 and is slotted to allow the passage of member 3 which is pivoted to a slider within the tubular link. This slider is acted upon by a spring and piston to control the pivot alignment. Specification 698,032,.[Group XXXV], is referred to.

Abstract: 1,034,232. Transistor switching circuit. MINISTER OF AVIATION. Feb. 8, 1965 [Feb. 27, 1964], No. 8217/64. Heading H3T. An electronic switch circuit comprises at least three transistors T1, T2, T3 connected with their emitter-collector paths in series and switchable means for biasing transistor T2 so that it may be either conducting or non- conducting. The transistors T2, T3 are connected as grounded base and transistor T1 may be grounded base as shown with the input applied to the emitter or may be grounded emitter with the input applied to the base. Transistors T2, T3 may be rendered conducting or non-conducting by a signal applied to the base of T2 or by transistor T4 which is normally conducting and hence maintains the transistors T2, T3 non-conducting. A negative-going switch pulse applied to the base of T4 raises its collector voltage allowing T2, T3 to conduct and a signal applied to T1 to be received at the tuned output 4, 5. Transistor T5 serves as a buffer amplifier between the tuned circuit and T3 and is omitted in Fig. 1 (not shown).
