Title: Improvements in tunable high-frequency electric coupling circuits
IPC: H03H2/00
Filed: 1936-03-19
Abstract: 477,304. Valve circuits for receiving wireless signals. HAZELTINE CORPORATION. March 19,1936, No. 8271. Void. Convention date, April 26, 1935. [Classes 40 (iii) and 40 (v)] Relates to means for coupling an aerial circuit to a wireless receiver in such a way that the overall gain is high and constant throughout the tuning range. The invention is described with reference to the ganged tuning circuits of a supersonic heterodyne receiver. The aerial is coupled to the input circuit of the pentode amplifier V1 by the common capacities Cs (furnished by the shielded lead-in S) Cp and Cc. Cc may be fixed but as shown is a variable condenser of the same design as the tuning condensers Ct, C2, C3. Owing to the presence of the coupling capacity in series with the tuning condenser in the input tuned circuit the effective capacity of that circuit differs from that of the circuit 10. The total coupling capacity is made as nearly as possible equal to Ca {R2/R - 1} where Ca is the antenna capacity and Ra and R are the respective resistances of the antenna and the input tuned circuit. Values of L and L2 can be chosen such that the circuits C, 10 remain matched throughout the range. In the modification shown in Fig. 4, the rotors of the ganged condensers Ct, Cc can be earthed. Specification 312,354, [Class 40 (v)], is referred to.

Filed: 1921-03-18
Abstract: 181,142. Cheshire, F. B., Cheshire, G. S., and Cheshire, T. A. March 18, 1921. Fluid-actuated valves.-Additional air is admitted to the induction pipe between the carburettor and the cylinder by a valve so actuated that the less the difference in the pressure existing in the induction pipe and the atmosphere the greater is the quantity of air admitted. The valve comprises a tubular casing 1 with inlet port 2, a part 15 leading to the induction pipe and a plug 11 a passage 10 in which is connected through pipe 19 with the induction pipe above the carburettor throttle valve 20, the connection being controlled by a screwed valve 12. The casing encloses a tubular piston valve 3 with central passage 4 the valve being coonnected through a stem 5 with a solid piston 6 carrying a rod 7 and loaded by a spring 8. A ball 23 and rod 21 serve to prevent the valve 3 from rising under certain circumstances, the ball being located in a cavity connected by a pipe 26 with the carburettor choke tube. At starting no air will enter the induction pipe the parts being in the posi tion shown in Fig. 2. After having started, the vacuum in the choke tube will remove the ball 23 and allow the rod 21 and valve 3 to rise uncovening the port 15 and allowing air to pass therethrough from the port 2 and passage 4. As the throttle is opened wider, the suction holding the piston 6 down becomes less and the valve 3 rises and uncovers still further the port 15. As the suction further decreases, the piston will move past the port 2 and allow air to pass directly beneath it to the port 15 in increasing quantity. At high speeds the lower end of piston 6 will rise and close port 15 thus cutting off the additional air.
