Title: Fm modulation system
IPC: G01S13/58
Filed: 1962-05-22
Abstract: 952,567. F. M. radar. BENDIX CORPORATION. May 22, 1962 [June 12, 1961], No. 19718/62. Heading H4D. In an F.M. radar system comprising a frequency modulated microwave transmitter and a receiver detecting portions of the reflected energy, loss of signal in the receiver due to " altitude holes " is overcome by using a plurality of spaced modulation frequencies to produce a composite receiver response formed from the overlapping separate responses for each modulation frequency. The invention is described as applied to the airborne F.M. Doppler navigation system described in Specification 949,681. As such the system comprises an antenna 11 sequentially radiating and receiving radiation in several directions under the control of an antenna switch 12. The antenna switch 12 also produces synchronizing signals triggering a two-stage counter 13 which provides four states controlling the frequency of a generator 14 in four steps up to 3% either side of 600 kc/s. The centre, 600 kc/s., signal is passed to a bistable flip-flop 21 to produce a 300 kc/s. signal. A further flip-flop 22 provides a 150 kc/s. signal. The 300 kc/s. and the 150 kc/s. signals are passed, together with a signal obtained by doubling the wobbulated 600 kc/s., via individual amplitude controls 20, to an adder 23 and thence to the repeller of a microwave klystron in the transmitter 16, to produce a multi-frequency modulated radiated wave at the antenna 11. A.F.C. 19 is controlled by the 1200 kc/s. signal. The receiver 18, I.F.'s are tuned to about 4.8 mc/s. and so select the 4th harmonic of the 1200 kc/s. echo signal, the 16th of the 300 kc/s. and the 32nd of the 150 kc/s. The three so selected 4.8 mc/s. harmonics are demodulated by a 4.8 mc/s. signal from quadrupler 17 and doubler 15 and are fed to a tracker 24 to produce Doppler beat frequencies which are converted in a computer 25, to give ground speed and drift angle signals, for application to a navigation computer or indicating device 26. The 300 kc/s. and 150 kc/s. flip flops 21 and 22 are switched off automatically above 5000 ft. when the switch 28 is connected to altitude switch 29, or, with switch 28 connected to the receiver A.G.C. 30, the flip-flops may be switched on whenever a position of null signal is detected in the receiver 18, using the wobulated 1200 kc/s. signal alone. In an alternative embodiment, Fig. 3 (not shown), the antenna switch 12 is used to sequentially energize 240 kc/s., 300 kc/s. and 400 kc/s. oscillators. The receiver is tuned to the lowest common multiple of the above three frequencies, i.e. 1200 kc/s., and the respective harmonics are selected from the three echo signals and demodulated with the appropriate multiple of the respective generated signal.

Filed: 1934-07-10
Abstract: 438,906. Valves. LINSLEY, E., and SARGENT, F. G., 17, Victoria Street, Westminster. July 10, 1934, No. 20195. [Class 135] [See also Group XII] A mechanically-driven timing-unit for water gas, and other cyclic processes, comprises one or more pairs of mutually adjustable rotating discs which have on their peripheries projecting rollers which engage with toothed rods paired together by rocker arms the motion of which is transferred to the valve mechanism of the plant. The timing unit comprises a wheel 5 driven from an external prime mover causing rotation of shaft 6, and, by reduction gearing 7, a shaft 9, which drives by reduction gearing 10, 11, a shaft 12 to which timing discs 13, 14 are secured, disc 14 being keyed to the shaft while disc 13 is attached to disc 14 by bolts 15. These bolts pass through slots 16, and a relative adjustment of the discs is obtained by loosening the bolts, and moving one disc, teeth 17 ensuring rigid engagement when the bolts are tightened. Each disc carries rollers 18. Rotation of the discs causes the rollers to engage alternately with projections or teeth on rods 23, 24, the raising of rod 23 by a roller 18 on disc 13 causing the lowering or replacement of rod 24 in position to be actuated by the roller 18 on disc 14. The alternate action obtained by the toothed rods is transmitted through rocker arm 22 to levers 25, 26, 27 giving a reciprocating motion to valve 3. The valve 3 may be a slide valve or a multiple port type, and causes the working fluid 1 to be supplied or exhausted from the power cylinder coupled to the appropriate valve in the water gas or other plant. One or more pairs of timing discs may be arranged on the shaft 12.

Title: Improvements in or relating to bearing mountings and a pressure responsive closure therefor
IPC: B61F15/22
Filed: 1951-08-28
Abstract: 712,493. Axle boxes. TIMKEN ROLLER BEARING CO. Aug. 28, 1951 [March 5, 1951], No. 20249/51. Class 12(1) An axle box 11 has a breather closure comprising a cap 24, Fig. 1. a flexible diaphragm 29 in the cap defining chambers 12 and 28, and a breather opening 32 communicating space 28 to the atmosphere. In known constructions of bearing mounting where the box 11 is closed by a non- flexible member, heating of the bearing forces oil out through the seal 17, whilst on cooling a vacuum is induced in the chamber 12 to draw in water or dirt. In the present construction the diaphragm 29 is of metal, with a mounting ring 30 which may be of rubber bonded to 29. At the other end of the bearing the ring 17 is thickened at 18 and clamped to the box. In operation, as the bearing temperature rises the pressure inside rises above the outer atmospheric pressure and causes the diaphragm to flex without affecting the seal 17 which is made less responsive to the difference in pressures. In a modification the rubber or rubber like diaphragm has rolled marginal portions and is held in place in the recess 31 by a split snap ring. In a further modification the diaphragm is held by a backing ring and screws.
