Title: Improvements in mercury vapour generators
IPC: F22B3/02
Filed: 1928-07-24
Abstract: 295,021. British Thomson-Houston Co., Ltd., (Assignees of Newkirk, B. L.). Aug. 4, 1927, [Convention date]. Vapour engines.-In a mercury-vapour generator a reduced quantity of mercury is employed and vapour is generated in such a manner as to contain particles of liquid mercury, in order to increase its cooling efficiency. The generator may comprise sets of long tubes 2 of small bore, each set comprising a number of tubes welded together. The lower portions only of the tubes contain liquid mercury and are intensely heated. the upper parts of the tubes being protected from heat. For this purpose a screen 10 of refractory material may be secured to the tubes by brackets 11. The vapour may be given a whirling motion by means of twisted strips 9, or the tubes may be of flattened section. The tubes discharge into the drum 6 by means of pipes 5, which are curved in order to cause a whirling motion of the vapour in the drum and consequent deposit of the suspended liquid, displacement of the liquid in the drum being prevented by means of a grid 6<A>. Liquid mercury passes from the drum to the tubes 2 by a pipe 8.

Abstract: 586,617. Photographic developing apparatus. HALL, HARDING, Ltd., BUNGAY, J. A., and FAUX, F. G. Nov. 3, 1944, No. 21565. [Class 98 (ii)] Photographic developing apparatus comprises a perforated hollow cylinder rotating in contact with an endless travelling band arranged to wrap round the major portion of the cylinder and effectively cover the perforations in that portion of the cylinder, with stationary means mounted in the interior of the cylinder for closing the lower portion and provided with pads or doctors for sealing that portion of the perforated cylinder not covered by the travelling band. As shown, the hollow perforated cylinder 1 mounted in bearings in the body 4 rotates in contact with the endless travelling band 2 tensioned on the rollers 3. A stationary semicylindrical trough 7 provided with sealing pads 8 seals the uncovered part of the cylinder. Ammonia solution may be vaporized in the cylinder 1 by the heater 6, or may be evaporated in an external unit and fed into the cylinder, the uncovered part of the cylinder being then sealed internally by any suitable device. The cylinder and endless band may be driven at different peripheral speeds to prevent uneven distribution of the gas. The heater 6 accelerates development and dries the drum surface at each revolution.

Abstract: 151,154. Gray, J. G. Sept. 8, 1919. Gyroscopic apparatus.-A steering-indicator for moving vehicles comprises a frame 8 mounted in gimbals in a frame 4 which is mounted in gimbals in uprights 15 carried by a base 16. Gyroscopes 1, 9, are secured to the frames 4, 8 respectively and their axes are stabilized into the vertical by rotating erectors 3, 10 of the kind described in Specification 130,697. To the frame 8 is also secured a gyro 11 rotating on an horizontal axis, or whose spin has a component around the horizontal. When turning motion of the vehicle carrying the apparatus occurs, the gyro 11 exerts a torque on the frame 8 and tilts it about the axis 6, the tilt being indicated by a pointer 17 and scale 18. If the vehicle be steered so as to maintain the pointer at zero it follows a straight line course. The movements of the pointer may be made to operate a servo-motor controlling apparatus for training and stabilizing the base 16 in azimuth; or the servo-motor may control the steering-gear of the vehicle. The frame 4 with attachments is preferably in neutral equilibrium about the axes 12, 14, and the frame 8 is in neutral equilibrium about the axes 6, 7. In a modification, the two gyroscopes 1, 9 are separately mounted on pedestal bearings.

In the arrangement described there are several vertical multi-collector transistors on each side of the common linear emitter zone 10, the resistance of which is reduced by heavily doped P + strip 11 diffused simultaneously with contacting zone 3, and a P zone 7 provides isolation from conventional bipolar circuitry formed in the adjacent part of the epitaxial layer. Emitter zone 4 can be brought nearer the surface of the epitaxial layer to improve # by a further donor diffusion into the epitaxial layer after it has been partially formed.

Abstract: 1293780 Automatic steering control SPERRY RAND CORP 19 April 1971 [2 March 1970] 22249/71 Heading G3R In an automatic steering system for a marine vessel, e.g. wherein a heading error signal # e  from a gyro compass system results in a rudder order signal applied to a rudder positioning servo 60, a potentiometer 23 provides a range of thresholds corresponding to a range of yaw angles, and a low gain mode is effective within the preset yaw zone whilst a high gain mode is effective outside the yaw zone. The heading error signal # e  from source 10 is applied to an operational amplifier 11, with a low pass filter 12, 13, and limiter 14, and then to the threshold circuit 21 including the potentiometer 23 the circuit 21 providing a bipolar threshold. Source 10 also provides the heading error signal to an integrator 24 including amplifier 25, integrating capacitor 26 and integrating resistor 27. The signal is applied via a fiveposition integrator gain controlling switch 30 positioned in accordance with the vessel 10 characteristics and loading. A field effect transistor 35 functions as the gain controlling element of the integrator. The integrator has a limiter circuit 36 and is reset to a reference condition by a signal on a reset line 37 when a change in course is commanded. Source 10 also enables the heading error rate to be obtained through a differentiator 40. Signal # e  is applied via a rate adjust potentiometer 41 to a tapped voltage divider 45-49, with taps connected to the wiper arm of a five-position switch 52 gauged with switch 30. Switch 52 selects the gain of differentiator 40 in accordance with the vessel 10 loading and dynamic characteristics. The signal from switch 52 is applied via a differentiating capacitor 44 and an adjustable low pass filter 53 to the amplifier 42 across which the differentiating resistor 43 is connected, as well as a limiter 54. The amplified and filtered heading error signal provided by amplifier 11, the integrated heading error signal from integrator 24 and the differentiated and filtered heading error signal from differentiator 40 are applied to a mixer circuit 55 including a conventional summing network. A limiter circuit 66 limits the amplitude of the rudder order signal, limiting the bipolar signal output of amplifer 56 and providing a single adjustment to vary simultaneously the opposite polarity reference voltages.

Title: Improvements relating to electronlc timing circuits

IPC: H03K5/13
Filed: 1963-06-05
Abstract: 1,008,820. Timing circuits. SOUTH LONDON ELECTRICAL EQUIPMENT CO. Ltd. May 27, 1964 [June 5, 1963], No. 22469/63. Heading H3T. A timing circuit includes a transistor having a charging capacitor connected to its base and a cyclically varying voltage on its emitter. In the rest position the input at I/P is negative, transistor TR1 is conducting, and transistors TR2, TR3 and TR4 are cut off; C1 is therefore short-circuited by TK1 and cannot charge. When the input at I/P becomes positive, it is applied through MR3 to cut off TR1 and C1 starts to charge during each negative half-cycle of the A.C. source A. The charging voltage is also applied to the base of TR2 in similar increments and ultimately it reaches or exceeds the peak voltage on the emitter of TR2, i.e. the algebraic sum of - Ve and the positive peak of the A.C. supply E; the latter is of the same frequency and phase as the source A. TR2 then conducts and turns on TR3. Current now flows through R10 to turn on TR4 and give a positive signal at the output O/P. This signal is fed back through R6 to hold TR3 conducting. The delay between input and output depends on the charging rate of C1 but is also fixed at predetermined values by the phase of the A.C. supply since TR2 can conduct only during the first part of the half-cycle in which C1 is not being charged and TR3 can conduct only near the peak of the supply voltage. This minimizes errors due to component tolerances. The circuit is reset by reversing the polarity of the input I/P, thus turning on TR1 through diode MR3 and cutting off the other transistors through MR4. The circuit can be used for process timing, e.g. in welding, or for frequency division. Two or more such circuits can be joined in cascade to provide outputs at different time intervals.
