Patent GB-806785-A (GB)
Title: Improvements in electromagnetic detecting and tracking devices
Inventor: GUTTON HENRI
IPC: G01S13/70
Filed: 1957-04-17
Abstract: 806,785. Radar. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 17, 1957, No. 26409/55. Class 40 (7). In a radar system a pulse transmitter generates short pulses of radio-frequency energy of steady pulse repetition frequency governed by modulator 1. The carrier frequency of the pulses is synchronized with the output of master oscillator 4 through switch 5 also controlled by modulator 1. The pulses are transmitted from aerial 6 and there is also generated in transmitter 3 an intercalated series of second unsynchronized low-power signals which in the absence of echo responses are progressively and recurrently swept in time position between the first (transmitted) pulses by means of modulator 2. When echo responses are received, as from a target 20, the second pulses will eventually scan to a position coinciding therewith. On coincidence the echo pulses returning to transmitter 3 synchronize the carrier frequency of the second pulses. The second pulses although not strong enough to be effectively radiated are passed to mixer 7 where they are mixed with the output of oscillator 4 to give an output which consists of signals of the Doppler shift frequency associated with the target 20. This Doppler frequency is amplified at 8 and integrated at 10. The integrator output is proportional to the radial distance from initial target " lock-on " and, when it is added to a potential available from unit 2 representing the " lock-on " range, it enables a continuous indication of target range to be presented on meter 11. The output of the integrator is also fed to modulator 2 to prevent further sweep and to cause the second pulses to " follow " the echo signal. In order to determine the bearing of the target from a radar it is known to have two spaced aerials and to measure the difference in phase of the echo signals from the target received thereby. Where the aerial spacing is small, relative to target range, the difference in phase between the Doppler shift beat frequencies is the same as that between the echo signals and can likewise be used to determine bearing. According to another embodiment of the invention two transmitters with separate spaced aerials and separate mixers but with common modulators 1 and 2 and master oscillator 4 provide two Doppler frequencies the phase difference between which is measured to indicate bearing (Fig. 3, not shown). A single integrator associated with one of the mixers is used to determine distance and to provide a signal applied to modulator 2 to cause the second pulses to follow the echo signals. A further pair of additional transmitters can be used to give the elevation of the target by the same means.

IPC: F02B1/00
Filed: 1922-09-30
Abstract: 189,096. Rateau, A. Nov. 12, 1921, [Convention date]. Spray carburettors. -In aircraft engines wherein a p u m p draws fuel from a main or auxiliary reservoir and dipscharges it into the float chamber of the carburettor to which air is fed under pressure, the reservoir at low altitudes is in communication with the atmosphere but at high altitudes is placed, by a manometric device, in communication with the pressure-air passage so as to be subject to a fraction of the pressure therein. A pump A draws fuel from a reservoir B or from a small auxiliary tank and delivers it to the float chamber C of the carburettor open to the passage D to which air is supplied under pressure. The passage D communicates through a pipe E with a cylinder containing a valve F actuated through a rod J by a manometric box I in a chamber H. The valve is loaded by a spring K adjustable by a cap L provided with an aperture M. A pipe G connects the cylinder and chamber H, and a pipe E' the chamber H and reservoir B. At low altitudes, or when the atmospheric pressure exceeds that in the box I, the valve F is lowered and the reservoir B placed in communication with the atmosphere. As the altitude increases and the atmospheric pressure decreases, the valve F is raised and some of the pressure in the pipe D is transmitted to the reservoir B, which, being subject always to only a small pressure, may be made of thin metal.

Abstract: 486,108. Bakers' &c. ovens. BAKER, B. D., and BAKER PERKINS, Ltd. Sept. 30, 1936, No. 26508. [Class 51 (ii)] In a recirculation heating system for bakers' ovens the arrangement of the heating tubes or conduits is such that a heat gradient in one direction of flow of the gases is balanced or modified by a corresponding heat gradient in the reverse direction, and that there is uniform heating of the oven transversely to the direction of flow. In the arrangement shown the heating arrangements for each half of the length of the oven comprise tubes 18, 20 for top heat and 19, 21 for bottom heat, connected respectively between inlet and outlet headers 3, 3a, 4, 4a: and 7a, 7, 8a, 8, so that the heating-gases flow in opposite directions through the two sets of tubes in each tier. Outlet headers are superposed on inlet headers, and the connecting tubes may cross as shown or may be cranked to bring them into the same horizontal plane for the greater part of their length. Even distribution of gases between the headers and the flues may be promoted by decreasing the cross-section of the headers in the direction of gas flow therethrough, and the quantities of gases flowing in the two directions may be controlled by valves. The reverse flow may be through the adjacent limbs of U-tubes, and in a modification described with reference to Figs. 4-7, (not shown), the heating-system comprises partitioned flat box flues through which the heating-gases flow first on the side nearer the goods space and then on the side remote therefrom.

The invention concerns a system whereby a bill of quantities can be recorded on punched tape by the use of a keyboard and an electronic pencil or tracker in conjunction with architect's drawings. Electronic pencil or tracker. Each time the pencil 10, Fig. 2, presses on the drawing a switch 16 is operated. Alternatively, as the tracker 11 is moved along a line representing a conduit, say, a cam operates a switch at the rate of sixteen times per inch. The trailing edge of the resulting pulses picked up by a loop antenna below the table are used to operate a counter-register 21, allowance being made at 19 for the scale of the drawing. For each type of equipment the estimator uses the first three banks of a keyboard according to a code to control a microfilm projector whereby he can determine the exact code of the equipment. He then sets up the remainder of the code number, provision being made for alteration. The estimator then uses the pencil or tracker to register the quantity concerned. Depression of a record key then converts the information into teletype code and punches it on to a tape. A dial 26 may be used to preset the register or to add to the registration, e.g. in the case of vertical lengths of material. Audible warning. Each operation of the counter is accompanied by a click.

The applicator roller 12 is hollow and is heated by water passing through it, the water being supplied from surge tank 24 and heated in heatexchanger 36. Baffle 14 is provided in the applicator roll to prevent the direct flow of water from inlet to outlet. Heat is supplied to the heat exchanger by means of steam supplied via conduit 46 and valve 48 which is operated in response to the temperature, as registered by sensor 40, of the water between the heat exchanger 36 and the roller 12. This permits the temperature of the surface of roller 12 to be maintained at between 5‹ and 15‹F below the gelatinization point of the adhesive. The roller is rotated by motor 62 which also controls a switch 60 by means of a relay 58 so that pump 34 can only circulate the heating water when the roller is rotating.  As illustrated in Fig. 5 the applicator roller 12 may rotate in a bath of adhesive 108 in cooperation with a cooled doctor roller 110.
