Title: Landing gear enabling an aircraft to land on and take off from unprepared ground
IPC: B64C25/00
Filed: 1946-04-24
Abstract: 647,642. Aircraft landing gear. SAPORTA, A. April 24, 1946, No. 12335. Convention date, Feb. 23, 1940. [Class 4] An aircraft landing gear comprises three or more skids which may be provided with wheels and may each consist of two parts pivoted together and provided with a spring at the pivot, the skids being independently mounted at their upper ends on a common axis movement about which is constrained by a spring. In the construction of Fig. 2, three or more skids such as 4 are independently mounted about an axis 5 and are each constrained by a blade spring 7 anchored at 8 and bearing against a cam 6 at the upper end of the corresponding skid. A compression spring 10 further constrains the blade spring 7. A stop 8a limits the movement of the skid and wheels 12, 13, 14 may be provided. The lower part of the skid may be pivoted to the upper part, a torsion spring being provided at the pivot. The skids may be capable of lateral play to permit them to deflect when they meet an obstacle. Skids may be placed under the nose and wing tips of an aircraft and a flying boat may be rendered amphibious by the attachment of skids to the hull. The Specification as open to inspection under Sect. 91 comprises also several modified constructions of skid, some of which may be mounted on members which are retracted during flight. It describes also the use of two or four feelers pivoted to the aircraft and longer than the landing skids ; when the feelers engage the ground their angular disposition indicates the height of the aircraft and the degree of irregularity of the ground. The disposition of the feelers may be indicated by lamps in circuits completed by contacts on the upper ends of the feelers and electrodes on the lower ends of the feelers may bo used to determine the conductivity, and thus the wetness, of the ground. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to thermionic valve arrangements
IPC: H03B5/10
Filed: 1934-04-24
Abstract: 423,772. Valve circuits for wireless reception ; valve modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Travis, C. ; 354, West Allen's Lane, Philadelphia, U.S.A.) April 24, 1934, No. 12343. Convention date, April 27, 1933. [Class 40 (v)] In an oscillator-modulator of the multi-grid valve type, the oscillation is sustained by energy fed back jointly by an intermediate anode-grid and by the plate of the valve, with the object of maintaining the oscillation at constant frequency and amplitude despite variations in the voltage of an outer grid. As shown in Fig. 4, applied to a superheterodyne wireless receiver, oscillation is sustained in the tuned circuit 12 of the inner grid 1 by two feed-back coils 13, 28, one of which 13 is connected through a voltage-reducing resistance 14 to the anode-grid 2, and the other 28 to the valve plate 6. The incoming wave received at 19 is applied to the grid 4, which is shielded from the other electrodes by screens 3, 5 and volume control bias, automatic or manual, is applied to the grid 4 through the lead 20. When either coil 13 or 28 is used separately, variation of the control bias on the grid 4 alters the frequency and amplitude of the local oscillation, but by suitably proportioning the coils and using them jointly, the effects neutralize each other. A single feed-back coil may be used connected wholly or in part to both anode circuits, Figs. 2 and 3, (not shown). When applied to a transmission modulator, an audio-frequency transformer is used in the input to the grid 4, Fig. 5, (not shown). The Specification as open to inspection under Sect. 91 includes a superheterodyne receiving circuit in which only the coil 13 is used as a ack-coupling to the circuit 12, the plate 6 being connected through a neutralizing condenser to a coil coupled to the signal input circuit 19. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 408,256.
