Title: Improvements in or relating to electric frequency modulation systems of communication
Inventor: MCLEOD THOMAS SYMINGTON
IPC: H03C3/08
Filed: 1949-06-24
Abstract: 662,494. Frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. June 24, 1949, No. 16791/49. Class 40 (v). Non-linearity in the frequency modulation of a radio transmitter by a wide-band signal is reduced by a negative feed-back arrangement. The signal at terminal 1 is applied through a buffer amplifier 14 to a modulator 2 controlling the main transmitter 3. It is also applied to an auxiliary modulator 5 controlling a low-power oscillator 6 of a kind known to give good linearity, and which may be of ultra-high frequency, e.g. 4000 mc/s. The modulated output may be stepped down in frequency, e.g. to 60 mc/s., by an oscillator 8, mixer 7, and filter 9. It is then mixed at 10 with the output from the main transmitter, and the difference frequency is selected by a filter 11. This frequency carries no modulation so far as the desired signal is concerned, but any distortion components introduced in the main modulator is present in the output of the mixer 10, is detected in the discriminator 12, and is fed back to the modulator 2 through an amplifier 13 in such sense as to counteract the distortion. The frequencyreducing stages 7, 8, 9 may be omitted.

Title: Improvements in soot removal apparatus for water tube and similar boilers
IPC: F28G3/16
Filed: 1923-06-28
Abstract: 200,100. Westerberg, C. A. A. June 29, 1922, [Convention date]. Cleaning, fluid-pressure processes for.-An apparatus for cleaning soot from water-tube and like boilers consists of a steam pipe 10 arranged at each of the positions 2-8 and rotated by means of sprocket wheels 12 and chains 13. The rotating pipes are pivotally mounted on the watertubes by means of suspension straps 9 and are provided-with nozzles directed towards the spaces between the tubes. The nozzles are fan-shaped, having a comparatively small inlet opening 4 and a flared outlet 15. The nozzles are arranged so that the longitudinal direction E-E of the outlet opening is inclined to the plane determined by the inlet opening and the axis of rotation, that is the latter is always skew to the direction E-E. The cross-section of the outlet opening may be substantially elliptical or alternatively eggshaped. A fixed steam-pipe 11 is jointed to the movable part 10 by ordinary packings, the movable part having an inlet 17 from the fixed casing 18. On rotation of the pipe 10 the inlet is closed when the nozzles are directed upwardly away from the bank of tubes. This arrangement constitutes an independent cut-off for each rotating pipe and eliminates the necessity for separate valves.

Title: Improvements in and relating to automatic reclosing mechanism for electric switches and the like
IPC: H01H75/04
Filed: 1937-06-17
Abstract: 484,861. Automatic circuit-breakers ; protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. June 17, 1937, No. 16904. Convention date, June 17, 1936. [Class 38 (v)] A high-speed reclosing mechanism comprises two separate sources of operating power, means controlling one of the sources for closing the breaker, tripping means for causing a circuit-opening operation of the breaker, and means responsive to the opening operation for controlling the other of the sources of operating power so as to cause initiation of a reclosing operation of the breaker automatically prior to completion of the circuit-opening operation. The breaker lift-rod 10 is operated from a rod 6 through parallel-motion linkage such that it is lowered to open circuit by upward movement of 6. The latter is connected by a guided pivot 5 to an intermediate point of a floating lever 4 having pin-and-slot connection 32 to each of two bell-crank levers 31 which are connected by thrust-transmitting overset toggles 29, 30 to weighted levers 28. The actuating means comprise a pair of centrifugal devices 2, 3 driven by pivoted motors 21 and linked at 27 to the weighted levers 28 which tend to reset the flyball linkage 24 as shown in the case of device 2. In order to close the breaker to the position shown, a hand-switch 37 is moved to contact 37a to make, over closed contacts 40, 41, the circuit of a coil 38 which energizes the motor 21 of device 3. The lever 4 is rotated clockwise from a horizontal position against stop 35 into the position shown, where cam 46 opens at 41 the circuit of coil 38. The parts are retained by the toggle. Tripping is effected by a trip coil 33 energized over contacts 44 either by a pressbutton 45 or trip relay 43, the tripping action causing the return of 4 to horizontal position with opening of contacts 44 and closure of contacts 48. Reclosure may be again effected by moving hand-switch 37 to contact 37a, but if automatic reclosure is desired, hand-switch 37 is moved to contact 37b, so energizing coil 49b to deflect a latch 49a, so allowing contacts 49 to close. When the breaker is tripped by coil 33, and the right-hand end of 4 rises and allows 48 to close, the circuit of the coil 47 for the motor 21 of device 2 is made, so that the latter device recloses the breaker at once automatically, leaving devices 2, 3 in positions opposite to those shown. In closing, cam 50 moves contact 49 to relatch it open, so preventing more than one automatic reclosure if the breaker is tripped open by coil 53 energized over contacts 51. Manual reclosure can, however, be effected by means of contact 37a, and if 37b is again engaged, a further automatic reclosure will be produced. In addition to automatically initiating the reclosure, the arrangement provides a dashpot effect near the end of the opening stroke, by lowering one end of the lever 4 before the other end roaches its buffer.

Title: Improvements in and relating to processes for carrying out anion exchange reactions in aqueous liquids
IPC: B01J41/04
Filed: 1940-12-02
Abstract: 543,212. Purifying water. PERMUTIT CO., Ltd., (Permutit Co.). Dec. 2, 1940, No. 17154. [Class 46] In order that organic acid-adsorbing or anion exchange material used in treating water may retain its efficiency for longer periods the oxygen content of the water is reduced to 1 milligram per litre or less before it comes into contact with the treating material. For this purpose the water may be passed through a tower in which a partial vacuum is maintained, or substances which will combine with oxygen, such as ferrous compounds, iron, aluminium, zinc, magnesium or their alloys, may be introduced into the water. In this way a metal oxide may be formed which will also remove silica from the water. Metals may be introduced into the water electrolytically by passing it over, for example, aluminium or iron anodes. If water is being treated successively with hydrogen-ion exchange material and anionexchange material, part of the water from the hydrogen-ion-exchange material may be passed over iron and, after removal of the ferrous compounds formed by precipitation or coagulation and filtration, returned to the main stream entering the hydrogenion-exchange material. Alkali may be added to ensure precipitation. Specification 450,309 is referred to.

Abstract: 201,357. Mitchell, E. A. June 21, 1922. Safety cut-off valves.-In a fluid-pressure distributing system wherein reducing valves are used, a stop valve is placed on the high pressure supply side of the reducing valve and is held open mechanically until the pressure on the low pressure consumption side is so far increased as to release the trip holding device. The valve is re-set by hand. The pressure reducing valve a, Fig. 1 is connected by levers b to a loaded diaphra.gm c, the inlet d thereto being connected by a pipe e to the outlet from the high pressure valve h. The latter is connected by levers to a balanced lever o which has a shoulder catch r adapted to engage with a, trip lever t. The arm u of the lever t is in the path of a rod v on a piston y which is subjected to the reduced pressure in the casing z. The piston has a liquid seal. When this reduced pressure increases the piston y is forced up to contact with the lever t, which is thereupon disengaged from the lever o, and the valve h is closed. The high pressure valve casing may be integral with the reducing valve casing. A double-disc balanced reducing valve may be used.

Title: Improvements in or relating to toothed gearing
IPC: F16H55/08
Filed: 1931-06-13
Abstract: 377,377. Toothed gearing. GEAR PROCESSING, Inc., 6700, Grant Avenue, Cleveland, Ohio, U.S.A.-(Assignees of Fehr, R. B. ; 79, West Bethune Street, Detroit, Michigan, U.S.A.) June 13, 1931, No. 17255. Convention date, March 19. [Class 80 (i).] Contact during the arc of approach is prevented by relieving, either gradually, Fig. 11, or abruptly and uniformly, Fig. 1, the addendum or dedendum portion of the working faces of one of the gears, leaving unrelieved the other portion and the portion on the opposite face corresponding to the relieved portion of the working face, and also leaving unrelieved the working face of the other gear. For gearing in which one wheel 10, Fig. 1, always drives and drive is always in the same direction, either the addenda 12 of the working faces of the teeth of the driven wheel 11, or the dedenda of those of the driving wheel may be relieved. When the direction of drive is always the same, but either wheel may drive, such as in a motor vehicle transmission when the car coasts against engine resistance, relief is provided also on the addenda of the trailing faces of the normally driving wheel 21 as shown in Fig. 11, or on the dedenda of those of the driven wheel 20, or alternatively the dedenda and addenda are relieved on opposite faces of the driving or driven wheel only, the mating wheel being wholly unrelieved. For helical gears, a high helix angle, low pressure angle and fine pitch are used to obtain at least three pitch point contacts, that is at least two tooth contacts in the axial direction. The tooth relief may be completely or partially formed during the original tooth-cutting operation by lapping, grinding or burnishing, or by treatment after the teeth have been correctly profiled. After heat treatment the tooth contours are made uniform by a reciprocating internally toothed complementary lap which is rotated relatively to the wheel during non-engagement periods. The Specification as open to public inspection under Sect. 91 (3) (a) describes also an arrangement in which one wheel always drives but the drive is in either direction. For this purpose relief is provided on either the dedendum portions of both sides of the teeth of the driving wheel or the addendum portions of both those of the driven wheel. This subject-matter does not appear in the Specification as accepted.
