Title: Sampled signal detector
IPC: H04W84/02
Filed: 1977-05-23
Abstract: 1524019 Selective signalling MOTOROLA Inc 23 May 1977 [10 June 1976] 21664/77 Heading G4H A signal (e.g. tone) is detected by comparing a portion of the signal with a portion of the signal received previously to detect correlation therebetween, varying the interval between successive portions each time correlation occurs, and providing an output signal after the occurrence of a predetermined number of successive correlations. In a first embodiment, each portion is sampled as a series of 64 bits and with two successive portions established in respective shift registers and corresponding portions of a reference signal established in respective further shift registers, each shift register is loop-shifted and corresponding portions of the input signal and reference compared serial-by-bit, bitinequalities being counted. If either count exceeds a threshold, the reference portions are shifted by one bit position and the process repeated, until a relative position is found in which neither count exceeds a threshold or all possible relative positions have been tried. Then, after a predetermined interval, a new portion is sampled from the input signal and from the reference, and the earlier existing portion of each is discarded, the interval being shorter than before in the case of neither count exceeding the threshold and the same as before in the case of all relative positions having been tried, and the above comparison procedure is repeated. When each of a series of progressively shorter predetermined intervals has been used, as above, a "detection" output is produced. As a modification, bit-inequality thresholds equal to "one" could be used, dispensing with the counters. A series of tones could be detected, using respective references. In a second embodiment, portions of the input signal are compared with each other, not via the mediation of a reference as above, but by shifting them into a chain of shift registers with interposed inverters and using a register network for parallel-by-bit comparison. In the second embodiment (though not the first), the interval between portions sampled from the input signal must be an integral multiple of the period of the signal to be detected.

Title: Improvements in aeroplane propellers
IPC: B64C11/36
Filed: 1931-07-30
Abstract: 378,196. Screw propellers. SCHROEDER, R. W., Glenview, Illinois, U.S.A. July 30, 1931, No. 21768. Conventlon date, Aug. 2, 1930. [Class 114.] An automatically variable pitch screw propeller is provided with an adjustable stop mechanism operated by the pitch variation of the blades to determine different limiting pitch position of the blades. The mechanism is adapted to operate under the control of the pilot who, by slowing down the speed of the propeller and then increasing it, causes the blade to change from one pitch range to the next. The boss 2 of the propeller has spigots 4 upon which the socket ends of the blades 9 are mounted. Two journal roller bearings 10, 15 and a thrust bearing 23 to take centrifugal forces are fitted over the spigot. On the for-' ward extension of the propeller shaft is secured a bracket 31 which supports a drum 36 and upon this is wound a spiral spring 39 anchored at one end and at its free end carrying a shackle 49. Secured to each blade root is,a divided collar 41 having a wing extension 46 and this is connected by a cable 51 with the shackle 49. The spring 39 therefore tends to rotate the blades to a maximum pitch position. The blades are so shaped and disposed with regard to their axis of rotation that the centrifugal couple acting on the blades tends to move the blades to a minimum pitch position. For equalizing the pitch of the two blades a free ring 79 on the shaft has forked ends engaging rollers 76 on the split collars. 41. A stop member 81 is secured to one collar 41 and carries a pivoted spring-pressed pawl 84 which engages the teeth 87 of a ratchet member 69. The latter, a detent member 68 and a cam stop member 67 are supported on a pivot 66 on a flange on the hub. When the pitch changes and the collar 41 moves in a clockwise direction relatively to the hub, the tooth 86 of the pawl 84 engages a tooth 87 of the ratchet and rotates it to bring the low surface 89 or high surface 90 of the cam stop member 67 into a position such that on subsequent rotation of the collar 41 counterclockwise the stop 81 will abut against the low or high surfaces 89 or 90. Instead of sets of two surfaces more than two may be provided on the member 67.
