Title: Method and apparatus for modifying the characteristics of a seismograph amplifier
IPC: G01V1/24
Filed: 1940-02-19
Abstract: 536,747. Seismographs. CLEVELAND, F. J. (Socony-Vacuum Oil Co., Inc.). Feb. 19, 1940, No. 3133. [Class 106 (iv] Comprises a method of and means for recording seismic waves generated in the earth's surface by the detonation of a charge of explosive in which the waves which have travelled by divers paths from the shot point to detecting stations are detected and corresponding signals generated by the detector are amplified and recorded, characterized in that a gradual varying degree of amplification is imparted to the signals. Figs. 2a, 2b placed end to end illustrate a seismogram recorded with one form of the invention and shows not only definite first breaks, but also shows distinctly reflections from shallow substrata interfaces as well as those from deep interfaces. The charge 2 is detonated by a blaster 3, Fig. 4. The signal is communicated by conductors 4, blaster 3, conductors 5, the time-break circuit 6 and conductors 7 to a recording galvanometer 8 when it is recorded at the instant of detonation. A timer 9 places a record of time-intervals as transverse lines on the seismogram. The signal from the blaster-time-break is also communicated by conductors 10, switch 11 thrown to the left, and conductors 12 to a master control 1 which acts to control the gain in amplitude from a thermionic amplifier 13. The seismic waves are detected by the geophone 14 and converted into electrical waves of corresponding phase and amplitude. These pass by conductors 15 to the amplifier and then by conductors 16, 7 to the galvonometer 8. By throwing the switch 11 to the right and making the geophone 14 the one placed farthest from the shot point, the initiation of control can be accomplished by the direct travelling energy arriving at the point 14. Varying ways of arranging the amplifier circuits are described. The first energy detected will be given maximum amplification, after which the sensitivity of the amplifier will decrease to a predetermined low value so that reflections from shallow horizons can be intelligibly recorded and then automatically increases exponentially with time to a maximum value in such a manner that all subsequent reflections will be amplified to substantially the same amplitude throughout the period of time the reflections it is desired to correlate are recorded.

Title: Improvements in television synchronizing-signal separators
IPC: H04N5/10
Filed: 1940-02-19
Abstract: 537,878. Television synchronizing-signal separator. HAZELTINE CORPORATION. Feb. 19, 1940, No. 3138. Convention date, March 16, 1939. [Classes 40 (iii) and 40 (v)] Undesired random pulses are removed from received synchronizing television signals by first deriving from said signals a first signal limited to an amplitude of less than twice the amplitude of the desired pulses, and also a second signal having periodic maximum values corresponding in periodicity and phase with the desired pulses and in which the undesired random pulses appear if at all in a time distribution substantially different from that of the corresponding received random pulses, adding the two derived signals, and limiting the resultant to obtain the desired pulses. The apparatus enclosed within the dotted lines 21, Fig. 1, serves to separate the frame signals from line signals and from random signals as follows. The mixed signal a, Fig. 2, is fed by means of condenser 28 and resistance 29 to valve 30 having an output network 31, these devices being designed to limit the output to the part below the dotted line shown along signal a. The limited signal is then applied to a diode 33 and to a reflecting network 32 which feeds the delayed reflected signal also to the diode. The network operates as more fully described in Specification 531,712. The delay exceeds the width of line pulses x but is less than the width of frame pulses y, so that the combined signal appears as at b, Fig. 2. The diode is biased by means of resistance 36 and condenser 37 to limit the signal to the part above the dotted line shown along signal b. Hence the final output is as shown at d, Fig. 2, substantially pure frame pulses. The devices 22, 23, 24, Fig. 1, the device 23 being a. delay network, operate in somewhat similar fashion to isolate line pulses. In these devices, the delay is equal to the line scanning period, so that the line pulses add up while the irregular random pulses do not and are removed by the limiting operation. Specifications 491,728, 514,271 and 518,434 also are referred to. The Specification as open to inspection under Sect. 91 also comprised the subject-matter now described in Specification 538,587. This subject-matter does not appear in the Specification as accepted.

Filed: 1918-02-25
Abstract: 123,572. Paterson, A. D., and Oil Fuel Economizer, Ltd. Feb. 25, 1918. Spray carburettors.-The mixing chamber a contains a fuel nozzle b and a floating chokemember c, which is controlled by engine suction and controls the air, entering by an inlet g and the outlet of mixture through a conduit f; the greater the suction, the greater is the proportion of air to fuel. In the form shown, the member c has air inlet and mixture outlet apertures d<2>, d<1> and a contraction d controlling the space around the fuel nozzle. It is acted on by a light spring c<1> adjusted by means of a set-screw c<2> acting on the stem c<3> of a plate c<4>. The outlet f is screwed into the induction pipe and is controlled by a piston valve h actuated by a Bowden wire or other means, the uppermost position of the valve being determined by an adjustable screw h<2>. At starting, a valve is used to close the air inlet g, so that fuel alone is supplied to the engine. This valve in its lowest position allows air alone to pass direct from the inlet g to the outlet f, to dilute the mixture from a second carburettor. In a modification, Fig. 5, the floating member l includes a sleeve l' controlling secondary air inlets k, and is connected by rods l<3> to a, plate l<4> controlled by a spring l<5>. The plate l<4> is held down by a trigger device at starting to enable fuel alone to be supplied. The mixture outlet n is controlled by a piston valve m, which may be lowered to admit air alone from inlets o to the outlet n. The air supplies may be heated electrically or by exhaust gases, &c. The Provisional Specification states also that for heavy fuel an electric heating coil may be placed in or around the fuel nozzle or supply tube.

Title: Improvements in electric water heaters of the storage type
IPC: F24H1/20
Filed: 1945-02-12
Abstract: 597,408. Heating water. DRAFFIN, A. R. Feb. 12, 1945, No. 3502. Convention date, Dec. 13, 1943. [Class 64 (i)] [Also in Groups XI and XXIX] In an electric water heater of the storage type, hot water from a circulatory heater 6 is directed by a control device 13 either through a pipe 10 into the lower part of a storage vessel 2, so that all the water therein is gradually raised to the desired temperature, or through a pipe 11 to the top of the vessel to supply hot water for immediate withdrawal through a pipe 2a. The control device (see Group XXIX) may be manually operated but preferably directs water to the top of the vessel automatically upon the operation of a switch changing over from " off-peak " to " ordinary " tariff. In the example, communication between a pipe 9 and either of the pipes 10, 11 is controlled by a plunger moved by spring- controlled bellows containing a heat-sensitive liquid, the bellows being contained in a small water chamber surrounded by a low wattage heating coil, Fig. 2 (not shown), which may be brought into circuit either automatically upon operation of the change-over switch or independently thereof. Alternatively the plunger may be actuated by a solenoid &c. Small diameter pipes 26, 27 allow a small by-pass flow of hot water between pipes 9 and 11 when the heating coil of the diverter is on, and prevent steam accumulation and overheating of the water surrounding the bellows. A single thermostat is housed in a tube 25 and controls the heater 6 irrespective of the position of the control device 13.

Letter-spacing.-A carriage escapement member 131 is provided with teeth co-operating with three dogs 133, 134, 135 pivoted to a slide 137 and spaced about by a distance equal to an integral multiple of three times the spacing unit plus one such unit, the teeth of the member 131 having a pitch of three time said unit. When a key is pressed a stepped sector 171 is set according to the number of units of spacing required, and a shaft 228 carrying levers 147, 148, 149, 150 is rotated, the levers releasing the dogs and also releasing the slide 137 from a latch 143. The slide is then moved the required spacing distance to the right against the sector 171 by a spring 141, the carriage meanwhile being held by a set of retaining dogs. The dogs 133, 134, 135 are then restored and the retaining dogs released, whereupon the carriage moves to the left until the latch 143 re-engages the slide. Tabulating mechanism; carriage-return mechanism.-Actuation of the tabulating or carriagereturn key engages a clutch 244 on a continuously rotating shaft 70 to rotate a cam 243 and rotate a shaft 228 through a linkage 240, 239, 235. The shaft 228 carries levers 225, 226, 227 which release the dogs. At the same time, a lug 246 releases a latch 247, which is rocked clockwise, and a lug 254 disengages the clutch after 130 degrees of revolution. The carriage is now moved to the left by a spring or to the right by an electric motor until the carriage stop or left margin stop encounters the corresponding counterstop, which displaces a member 258 to release a pin 238 from a shoulder 237, a spring 236 releasing the clutch for re-engagement, through a linkage 257, 255, so that the cam rotates to its original position. The shaft 228 is also rotated to return the dogs to an intermediate position in which only the dog 133 engages the escapement teeth, the arm 245 resting against the lift of the latch 247. When the shaft 146 is rocked for a subsequent letterspacing, or when the back-space key is pressed, the latch 247 is swung counter-clockwise by a link 251 or a slide 199 respectively, to release the lug 246, returning the dogs to the control of the levers 147, 148, 149. Carriage release.-A manually operated bar 229 engages the end of the lever 227 to rock the shaft 228, the latch 247 controlling the return of the dogs in the same way as above.
