Title: Improvements in and relating to automatic control equipments for electric motors
IPC: H02K19/12
Filed: 1928-08-11
Abstract: 295,636. British Thomson-Houston Co., Ltd., (Assignees of Hough, E. L.). Aug. 15, 1927, [Convention date]. Regulation of exciting machines. - A synchronous motor 1 is started as an induction motor (on reduced voltage) by the closure of a switch 3 connecting the mains to a compensator 4, the motor field circuit containing an exciter machine 8 which is temporarily ineffective because its own field is greatly weakened by a high resistance 16. When the speed of the motor approaches synchronism a relay 18 responsive to induced alternating current in the motor field releases its armature and by short-oircuiting the resistance 16 causes the exciter to become effective. Direct current from the exciter, after rising to a determined value, then energizes a relay 15 which switches-in a change-over relay 22 to bring about the opening of the compensator switch 3 and the closure of the full-voltage switch 5. At the same time a variable resistance is added to the exciter field, and a shunt is completed at the contacts 46 around the contacts of the relay 18. The foregoing sequence of operations takes place automatically after closure of a hand switch 9, acting through a master relay 10.

Title: An improved combined shackle, anti-vibration and shock-preventing device for springs of motor and other road vehicles
IPC: B60G15/02
Filed: 1923-09-19
Abstract: 226,282. Jensen, C. A., (Steuart, F. G.). Sept. 19, 1923. Laminar springs; vibration-dampers; dash-pots. -A combined shackle and shock absorber for the springs of a vehicle comprises two members relatively slidable and arranged at a rearwardly and upwardly inclined angle, one member being attached to the spring mounted on the road-wheel axle and the other attached to the chassis or upper spring. In Fig. 1 one member consists of a guide h secured to the chassis by a square or other section bolt m so as to prevent rotation but permit of limited adjustment. The other member a consists of a slide pivoted to the spring eye by a pin d. Movement of the slide in the rearward direction due to shock on the spring is scarcely impeded, but the return movement is retarded on account of the angularity of the guide. A lubricator q and passages r, t are provided for the slide and shackle pin, while pads p to exclude dust are attached to the slide. To increase the retardation of the return movement the slide in Fig. 3 is in the form of a half-nut engaging with a screw mounted in bearings 8 in the guide. On shock to the spring the nut moves rearwardly and rotates the screw, which is permitted to rotate freely by means of the pivot 4 bearing on the thrust plate 11. The return movement, however, causes the flat end of the screw to bear upon the thrust plate 16, and the friction set up impedes the rotation of the screw and consequently the return of the spring to normal position. In Fig. 6 the guide consists of a square-section cylinder h<2> in which is mounted a piston 24 attached to a piston rod connected to the spring by a slide a<2>. The piston is provided with spring-controlled flap valves 38, which open fully when the piston moves in a rearward direction but close when the opposite movement takes place, the fluid then passing from one side of the piston to the other through restricted apertures in the flap valves. Lubrication may take place by the escape through a small aperture 45 of the oil in the cylinder or independent lubrication may be provided.

Title: Restricted Stacking on Shallow Reflections
IPC: G01V1/36
Filed: 1966-05-26
Abstract: 1,152,353. Seismic signal processing. PETTY GEOPHYSICAL ENG. CO. 26 May, 1966 [2 June, 1965], No. 23741/66. Heading H4D. In a system for compositing common depth point seismic signals obtained using a plurality of seismic source-to-detector spacings, distortion of the composite signal is reduced by suppressing initial portions of the signals (where large rates of change of moveout are encountered). For traces recorded with sources and detectors at surface locations disposed on either side of a common reflection point, the lengths of these portions are greater for the wider sourcedetector spacings. In one embodiment, recorded traces reproduced in channels each including an amplifier are composited in a summing amplifier and the channel amplifiers are blocked for different initial periods according to the sourcedetector spacing. In an alternative embodiment a rotating magnetic drum with recording and reproducing heads whose separation is varied by a servo control imparts a time-varying delay (the moveout correction) to each seismic signal. The rate of change of moveout is determined from the frequency-modulation in the reproduction of a carrier wave signal recorded on a control track on the drum and scanned by a reproducing head moved together with the servocontrolled heads, and if the moveout rate of change is in excess of a threshold value the moveout-corrected signal applied to an output channel for summation is suppressed.

Title: Improvements in or relating to radio location equipment
IPC: G01S1/02
Filed: 1945-09-14
Abstract: 600,494. Radiolocation ; pulse generating circuits. CARTER, R. H. A. Sept. 14, 1945, No. 23824. [Classes 40 (vi) and 40 (vii)] In a radar receiver having a cathode-ray tube indicator on which received signals are displayed as intensity modulation of a time-base trace representing range, the gain of the receiver is automatically alternated between a high and a low value either during alternate time-base traces or during alternate groups, each containing a plurality of traces. The system is particularly useful in receivers having amplitude limiters in which signals from small objects may be swamped by permanent echoes at high gains and short ranges. In the case of a radial rotating time-base indicating azimuth as well as range, the receiver gain may be changed once every rotation. To change the gain, controlling pulses, for example the timebase trigger pulses or North radial scan brightening pulses, may be applied to a multivibrator having two steady states and the square wave output used either directly or through a relay to control the gain in the intermediate frequency amplifier of the receiver. Specification 587,185 is referred to. Pulse generating circuits. The multivibrator has a common trigger input T1 acting on the main valves V1 and V2 through diodes V3 and V4 introduced to prevent any possibility of a trigger pulse resulting in a further fall in the anode voltage of the conducting valve and failing to reverse the conditions in the circuit. Variable resistor R12 is provided for lining up the circuit and ganged resistors R6 and R11 control the amplitude of the square output waveform derived at T2.

Filed: 1958-07-24
Abstract: 875,684. Treating tobacco. BRITISHAMERICAN TOBACCO CO. Ltd. July 15, 1959 [July 24, 1958], No. 23873/58. Class 130. [Also in Group XIII]  Tobacco continuously passing from cutting to cigarette-making machines is conducted through a pneumatic drying system which entrains the cut-leaf introduced through a rotary-lock device 2 for conveyance through vertically arranged diverging-converging drying chambers 3, 4, to a separator 5. The dried product passes through a rotary lock 6 to the cigarette machine whilst the dust-laden air passes to a cyclone separator 7 from which the cleansed air flows through a fan 8 for discharge to atmosphere or recirculation, by which the humidity of the drying air is controlled, via ducting 11. The recirculation valve 10 is regulated by a device 12 responsive to the air temperature in the duct 13 between the chamber 4 and the separator 5. The air may be heated in a heater 1 by steam, electricity or fuel combustion . to a temperature of 320 ‹ F. Burnt combustion gases may be used as the drying and conveying medium. The air velocity through each chamber 3, 4 is such that the tobacco particles are caused to circulate therein if necessary until of suitable size and dryness for passage to the separator. The chambers may contain vanes or baffles, or tangentially disposed jets through which hot or cold air is admitted may be used to impart a helical motion to the rising particles. The drying system may comprise a single chamber 3 or 4. After leaving the system through the device 6 the tobacco may be cooled by passage through a similar system or it may drop from a rotating wire gauze drum 18, Fig. 3, through a baffled tower 14 in counter-current to cold air induced therethrough by a fan 20. The velocity of the air through the tower may be controlled by allowing further air to enter through a valve 22.
