Title: Improvements in or relating to navigational aid apparatus
Inventor: ATHERTON JAMES FRANCIS
IPC: G01S1/02
Filed: 1952-05-09
Abstract: 907,191. Radio/inertial navigation systems. AVIATION, MINISTER OF. May 11, 1953 [May 9, 1952], No. 11867/52. Class 40 (7). A navigational aid in a craft comprises a radio receiver 1 providing from time-to-time signals relating to the position of the craft, inertia apparatus 4 (e.g. suspended mass) adapted to compute the position of the craft from movements thereof, and auxiliary apparatus for effecting successive corrections of the apparatus 4 under the control of signals from the receiver 1. In an " H " system of aircraft navigation, strobe pulses within the receiver are locked to the incoming responder signals and are timed, not directly by error voltages produced in the receiver, but by signals derived from the apparatus 4 after the latter has been corrected. Error signals from 1 are integrated at 2, converted at 3 to represent cartesian coordinates, and applied to the mass-controlled computing-apparatus 4 to correct drift, and an output from this apparatus, converted at 3 into polar co-ordinates, is then employed to control the generation of the strobe pulses at 1. By this employment of inertia apparatus the radio link is able to operate with longer time intervals (e.g. one minute) and hence to use more powerful pulses which reduce the effect of jamming. In an alternative arrangement, Fig. 2, the error signals from the receiver 1 are integrated and converted into cartesian co-ordinates and the resultant compared at 6 with information from 4 to provide an error signal to maintain the apparatus 4.

Title: Improvements in and relating to hydrofoil assemblies
IPC: B63B39/06
Filed: 1960-04-04
Abstract: 924,374. Hydrofoils. M. A. T. TRASENSTER July 4, 1961 [April 4, 1960], No. 11896/60. Class 113. An hydrofoil assembly including a hydrofoil blade mounted for pivoting movement about an axis transverse to the direction of travel of the craft has control means comprising two drag elements arranged to cause a pivoting movement of the blade, the pivoting movement induced by the elements being in opposite directions and the relative drag on the elements so varying with the position of the assembly with respect to the water surface that the resultant pivoting effect is zero when the assembly is in equilibrium and when the assembly is not in equilibrium is such as to restore equilibrium thereof. In one embodiment the hydrofoil blade 1 attached to the shaft 2 has an upper drag element 3 with enlarged portion 4 and a lower drag element 5 with a stabilizing fin 7. A decrease in speed and consequent loss of lift causes element 3 to become further immersed and the drag on element 3 will rise above that on the element 5 to produce a turning movement to increase the angle of attack of the blade 1 and return the assembly to a position of equilibrium. In another embodiment the shaft 2 of the blade 1 has secured thereto a drag element 5, 10, 12 and via pinions 9 and shaft 8 a second drag element 3, 4 of different and tapering shape so that at a certain depth the drag on the two elements will be in balance whereas above this the drag on the element 5, 10, 12 will dominate and below it the drag on the element 3, 4 will dominate,
