Filed: 1962-05-10
Abstract: 955,050. Jet propulsion plant. UNITED AIRCRAFT CORPORATION. May 10, 1962 [May 10, 1961], No. 18107/62. Heading F1J. [Also in Divisions B7 and F3] A rocket powerplant has a solid propellant and a source of liquid propellant, means dividing the solid propellant into symmetrical segments about the axis of the power-plant, reaction means in the exhaust stream fromeach of the segments, and means for controlling the flow of liquid propellant through each of the segments so as to vary the reaction rate between the propellants in the segments and the resultant forces on the reaction means. Referring to Fig. 1, the rocket includes an outer casing 12 which terminates in an aft exhaust nozzle 14 formed as an annulus between the casing 12 and a streamlined central plug 16. The combustion section 20 comprises a solid propellant 22 formed with a plurality of axial passages 24, 26, the solid propellant 22 and the exhaust nozzle 14 being divided into segments by a number of partitions 30, 32. A header 40 is provided between each segment and an oxidiser tank 36 containing a suitable liquid under pressure, an injector portion 42 of each header 40 receiving oxidiser from a throttle-type control 44 by means of which the flow of oxidiser to the passages 24, 26 can be varied as desired. Each of the segments of the exhaust nozzle 14 contains one or more deflector vanes 50, 52 (Fig. 2), adjacent deflector vanes in adjacent segments turning the flow slightly in opposite directions. Hence, by varying the oxidiser flow by means of the controls 44, there will be differential forces between adjacent deflector vanes 50, 52 to provide a directional control for the rocket. A control system for a powerplant of the above type is described, also one for a power-plant having annular combustion segments and annular passages for the oxidiser flow. A tri-propellant hybrid rocket motor arrangement is shown in Fig. 6, a solid propellant 150 such as beryllium being provided with passages 152 and a pump 156 which drives a first fluid propellant such as hydrogen from a tank 154 through cooling passages 158 in the outer casing 160 of the rocket, through struts 162 and through a passage 164 around a plug 168 via passages 170, 172 to a turbine 174. The heated hydrogen drives the turbine 174 and flows through a passage 176 to one or more nozzles 178 in each of the passages 152. The turbine 174 drives a pump 180 and the pump 156, the former pumping a second fluid propellant from a tank 182 through a passage 184 to one or more nozzles 186 in each of the passages 152. A control system is provided to control the flow of both fluid propellants to each of the passages 152.

Title: Improvements in or relating to braking systems for vehicles
IPC: B60T13/14
Filed: 1940-12-31
Abstract: 545,670. Hydraulic brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and PARNELL, F. G. Dec. 31,1940, No. 18257. [Class 103 (i)] Braking systems for vehicles shown in Fig. 1 have one set of brakes operated by a master cylinder 10, and another set operated at the same time by pressure means, such as a pump 44 and accumulator 19, delivering pressure fluid through a pedal-controlled valve 18, Fig. 2, to an outlet leading to the brake cylinders, part of the same supply actuating a piston 15 for operating the master piston of cylinder 10. A lever 24 pivoted at its mid-point to the rod between the piston 15 and the master piston is connected to a pedal 27 and to the valve 18 so that either pressure system may be directly operated by the pedal if the other fails. Fig. 4 shows a master cylinder 53 with its piston 52 having integral with it a piston 51 receiving pressure to operate the piston 52 from a circulating system of the kind described in Specification 545,667. Until the pedal advances the thrust-rod 77 to move forward a plunger 57 to close the valve 73, 74 fluid from a pump enters a cylinder behind the master'cylinder through a port 64 and passes through the valve into a central passage in the plunger 57 and out to exhaust through port 65; as in the form shown in Fig. one set of brakes additional to one operated by the master cylinder is operated from the pressure supply used to actuate the master cylinder. In vehicles having more than two pairs of wheels a "tandem" master cylinder, such as that described in Specification 446,364, may be used for operating two sets of brakes. An exhauster to create a vacuum may be used instead of a source of pressure.

Title: Improvements in or relating to radar systems

Abstract: 656,094. Radiolocation. MARCONI'SWIRELESS TELEGRAPH CO., Ltd. July 7, 1948, No. 18301. [Class 40 (vii)] In a frequency-modulated radar system in which the direct and reflected signals are heterodyned to give a beat frequency indicative of the range, means are provided for indicating the distance of targets having a relative radial velocity within a predetermined range of velocities or for indicating the radial velocity. The invention utilizes the fact that the phase of the beat frequency produced by a stationary target, as observed at a predetermined point in successive modulation cycles, is constant whereas when the target is moving the phase will vary at a rate dependent on the Doppler shift frequency. The invention is described as applied to a known system in which the beat frequency output from 5 produced by heterodyning the direct output from the transmitter 2 and the reflected signal received at 5 is analysed by heterodyning it at 6 with a cyclically varying frequency from oscillator 7, and applying the resultant output through a band-pass I.E. amplifier 8 to a frequency changer 9, together with a second output from oscillator 7 to give short trains of oscillations having a frequency equal to the original beat frequency and which occur at a time relative to the variation period of oscillator 7 which is dependent on the beat frequency and hence on the target distance. In accordance with the present invention, the reconstituted beat frequency is gated at 10 by pulses of recurrence frequency equal to the modulation frequency which are produced by shaping at 11 an output from the modulating wave generator 3 the pulse duration being less than one quarter of a cycle of the beat frequency. The output from 10 comprises a pulse train amplitude modulated at the Doppler frequency, Fig. 2 (not shown), the modulation frequency being extracted by a low-pass filter 12 whose output is applied through a filter 13, passing the desired range of Doppler frequencies to an amplifier 15 and indicator 14, e.g. frequency meter or loud-speaker. Alternatively the phase of the gating pulses may be varied to maintain the output from 10 of constant amplitude, the rate of variation being a measure of the Doppler frequency. The output from filter 13 may also be applied to produce a P.P.I. or type A display of targets within a predetermined range of speeds. Since the range search is comparatively slow, a long time is required to complete a P.P.I. display and this may be reduced by combining the outputs from several systems searching different limits of range. In order to avoid ambiguities the modulation frequency should be at least twice the upper limit of Doppler shift frequencies.
