Title: Improvements in or relating to computing-appliances or indicatingscales for correcting altimeter readings
IPC: G01L11/00
Filed: 1921-03-03
Abstract: 180,763. Wimperis, H. E., Bygrave, L. C., and Capon, R. S. March 3, 1921. Multiple-indication apparatus ; index hands.- The observed readings of an aneroid altimeter are corrected for temperature at height by means of relatively slidable members bearing scales cf height and temperature. The apparatus is described as a calculator distinct from the aneroid instrument; but it may be incorporated with the latter in which case one member is set automatically by the mechanism. In the construction shown in Fig 1 for use with isothermally-calibrated altimeters a disc carries a height scale a having equal graduations from 6,000 feet upwards but increasing graduations below this height. Pivoted on this disc is a second disc b provided with Centigrade, Fahrenheit and absolute temperature scales which open out towards their lower ends. In use the disc b rotates so that an index d points to the uncorrected height reading whereupon the true height may be read opposite the observed temperature. In the form shown in Fig. 2 for use with altimeters corrected for mean temperature, the smaller disc f bears two height scales while the larger disc h is provided with an evenly divided scale of heights g and a temperature scale m. In Fig. 3, a single disc i has an observed height scale and a true height scale and supports a pivoted arm p graduated at l for temperature and having an index pointer k. In a further form the temperature member bears two scales namely of mean temperatures and of true temperatures at height, and also has duplicated index pointers.

Title: Improvements in and relating to methods of and mechanism for driving paper machines and the like
IPC: D21F7/02
Filed: 1920-03-11
Abstract: 158,468. British Thomson - Houston Co., Ltd., (General Electric Co.). March 11, 1920. Speed-maintaining systems.-In a paper machine or the like in which a plurality of units are required to run in fixed speed relation, the driving shafts of the units are each connected to auxiliary shafts all of which are constrained to run at the same speed and carry pulleys connected by belts with the driving shafts, whereby adjustment of the speed of any unit is permitted by shifting the belt of that unit. The units 1, 2, 3, Fig. 3, are each driven by a direct current motor 50, 60, having a variable resistance 62 in the field-wind. ing circuit, the driving shafts being connected through gearing 15, 16 and cone pulleys 17, 18 to the armature 13 of a three phase synchronous motor. A wattmeter 30 is inserted between each armature 13 and the synchronizing mains 20, 21, 22 and indicates both ways from zero, thus showing whether the corresponding synchronous machine is acting as a motor or a generator. Contacts 31, 32 on the wattmeters are connected to the oppositely-coiled field-windings 33, 34 of a pilot motor, the armature 35 of which operates through a worm to vary the resistance 62, to vary the input to the motor in accordance with variation in the load on any unit as indicated by the wattmeter, according as contact is made at 31 or 32, either automatically by the wattmeter needle or manually by push buttons. A fixed speed relation between the units is thus maintained, while at the same time the speed of any unit may be independently varied by shifting the belt 19 on the pulleys 17 and 18. In the modification shown in Fig. 4, the synchronous motors are dispensed with and mechanical synchronizing means is used. The means in this case consists of a shaft 73 having bevel wheels 76 gearing with wheels 75 connected through magnetic clutches 74 to shafts 72, the wattmeters being replaced by torsion dynamometers 30<1> connected to pilot motor circuits for controlling the resistances 62, as before.

Patent GB-649085-A (GB)
Title: Improvements in and relating to generation of electromagnetic waves
IPC: H01J25/78
Filed: 1946-03-11
Abstract: 649,085. Electron discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. March 11, 1946, No. 7533. Convention date, March 15, 1945. [Class 39 (i)] High-frequency electromagnetic waves for electric signalling or similar purposes are produced and propagated by directing an electric pulse of charge, or charges having a regularly varying density, against an oppositely moving electromagnetic wave. The principle of the invention is explained by reference to the Doppler effect and resides in the fact that a charge 3, Fig. 1, when moving in a direction opposite to a wave 2 from a source 1 will disperse or reflect the wave to produce, e.g at points 1, 4, waves which have frequencies greater and less respectively than that of the fundamental. It is shown that by using waves of 1 cm. length and electron beam voltages of the order of 300,000, waves of 1 mm. length can be produced. In one form, waves from a source 6, Fig. 2, are supplied through a probe 7 to a dielectric guide 5, and an electron beam from the gun 9, in respect of which the guide acts as anode, is directed through the reflecting filter 11. A high-frequency modulating voltage on the grid 13 causes the electrons to enter the guide as pulses of charge. When electron velocities of the order of the velocity of light are used, the guide should be of a length comparable with that of the modulating wave. The reflected waves pass through a filter 19 to an output guide 18 and may be frequency modulated by varying the anode potential by means of the movable arm 20 on the voltage source 12. In another form, two opposite streams of charge pulses 25, 26, Fig. 3, reflect waves from source 21 to produce waves 27, 28 ; further reflections will produce waves of still higher frequencies. In a further form, a magnetron 36, Fig. 4, comprising cathode 30, anode 31 and magnets 32 produces a rotary electron stream, which may be formed into pulses by the modulating voltage 33, to reflect the wave 34 in the guide 35. The output wave of higher frequency is reflected into the output guide 39 provided with the filter 40. A Barkhausen-Kurz oscillator may also be used. The Specification as open to inspection under Sect. 91 comprises also arrangements, contained in Specification 649,130, wherein frequencymodulated waves are produced in a wave-guide by means of a modulated electron beam which is deflected by modulating signals to and fro along a slot in the guide. This subject-matter does riot appear in the Specification as accepted.
