Filed: 1947-07-25
Abstract: 628,071. Photo-electric cells; thermionic valves. BRITISH THOMSON-HOUSTON CO., Ltd. July 25, 1947, No. 20113. Convention date, July 27, 1946. [Glass 39 (i)] A photo-cell and a thermionic gas-filled triode acting as amplifier are contained in separate compartments of the same envelope which is divided by a transverse metallic wall 4. This wall has a central aperture 5, and may be integral with the lower section 8 or with the upper section 11 of the envelope ; in the latter case a window 9 is provided. The upper compartment contains a frusto-conical photo-cathode 13, attached to wall 4 round the periphery of the aperture 5, and a central photo-anode 12 which is supported directly by the cathode 14 in the lower compartment. Concentric with the cathode are an anode 16 and a grid 15, the latter being attached to the wall 4 and thus to photocathode 13. The triode electrodes are supported from an insulating disc 17 through which also pass the various leads. This construction affords improved protection for the photocathode against heat from the triode section, and the protection may be further increased by an asbestos collar 36 mounted in the aperture 5. In a modification, Fig. 3 (not shown), the grid is as before, but the anode is mounted centrally under photo-anode 12, while the cathode is placed eccentrically, outside the grid. The filling may be mercury vaporized from a drop 35, or argon at 100/150 microns, or neon or xenon; alternatively the device may be completely evacuated. The tube may be used in the circuit of Fig. 5 (not shown) to operate a relay in response to a predetermined energy level from a source such as an incandescent or U-V lamp, X-ray tube, &c.

Patent GB-705023-A (GB)
Title: Improvements relating to carrier-current intercommunication apparatus
IPC: H04B3/54
Filed: 1951-08-28
Abstract: 705,023. Preventing inductive disturbances; signalling-over power circuits. COONEY, J. R. Aug. 28, 1951 [Sept. 6, 1950], No. 20285/51. Class 40 (4) [Also in Group XL (c)] In a carrier-wave communication system utilizing power lines as the transmitting medium, the receiver is muted in the absence of signals in order to eliminate line noise. A combined transmitter and receiver embodying the invention comprises a ganged control switch 10, 10b, shown in receiving position, having alternative " locking " and " non-locking " transmitting positions T<SP>1</SP>, T respectively. In reception, signals are fed from the power line 25b to the grid of valve V1 via condenser C8, coupling coil 20 and tuned circuit 15 ; the valve operates as a diode, rectified audio signals appearing across the R.C. combination R1, C1 which has a time-constant short relative to the interval between noise impulses. Audio signals pass via a condenser C4 to the grid of an amplifier V3 which is coupled to a further stage V2 feeding loudspeaker LS over transformer T2. According to the invention the valve V3 is disabled in the absence of signals by deriving its screen potential from the anode of a muting valve V4, via R.C. combination R3, C3 which has a relatively long timeconstant. The grid of valve V4 is connected by lead 24 to the detector circuit, so that in the absence of a signal the anode current and consequently the potential drop in the load resistance R2 is large : the screen potential and thus the gain of valve V3 is then low. The appearance of a signal causes the valve V4 to be biased back, rendering the screen potential of the valve V3 high, so that this valve then becomes operative. With switch 10 in a "transmitting" position, the anode and screen of valve VI are energized and the valve oscillates by virtue of inductive back-coupling provided between the tuned grid circuit 15 and a further tuned circuit 18 connected to the anode. To render the transmitting frequency close to that for reception a high value of grid resistance R1 is used and also a high grid excitation voltage : the coupling to the power line is also reduced by means of a tap on the coil 20 to obtain efficient. operation in the presence of heavy loading by the power line. The valve VI is anode-and-screen modulated, the loudspeaker LS being used as a microphone feeding valve V3 via a transformer T1 while the primary of transformer T2 acts as a modulation choke. Specification 490,281 is referred to.

Abstract: 517,866. Pneumatic separating. McCONNEL, HINDS, Ltd., HINDS, G. A., and McCONNEL, F. W. July 9, 1938, No. 20340. [Class 117] In the separation of hop leaves from flowers, the mixture is fed on to the upper run 12 of an endless conveyer 9 of open mesh material. A parallel endless belt 8 overlaps the conveyer and its lower run 13 forms the bottom of a vacuum chest 7 with a fan 6 mounted at the top. The conveyer 8 extends beyond the chest 7 at its delivery end and its upper run passes through a slit 18 in the side of the casing. At the overlapping parts of the conveyers, the lighter constituents of the mixture on the conveyer 9 are lifted and caused to adhere to the run 13 of the conveyer 8 until it passes out of the zone of the air current when it falls on to a guide plate 24 and conveyer 25. The heavier material remains on the conveyer 9 and is delivered on to a conveyer 28. In a modification, the vacuum chest is closed by a mesh disc rotating about a vertical axis, and the mesh feed conveyer 9 and a solid conveyer for delivering the light material are disposed side by side beneath the disc.

Fluid-pressure.-In vacuum brake apparatus a driver's valve is provided having means for placing the vacuum exhauster in direct communication with the train pipe, and the pipe on the locomotive, the means also serving to admit air to the train pipe only, or to the train pipe and the locomotive pipe, and to cut the electric motors out of the power circuit. The driver's handle also controls the vacuum pump. The valve chamber B has three compartments, the first communicating with the train pipe b, the second e with the vacuum exhauster pipe a, and also with the locomotive pipe through a non-return valve g, and the third f with the locomotive pipe c direct. Mounted on the spindle i is a valve member h adapted to be rotated by a handle j. The lower plate of this member has ports k, l, m, Fig. 4, adapted in certain positions to register with ports (shown shaded in Fig. 2) in the upper plate of the chamber B. The member h is divided by a partition n, and the upper plate has perforations opening one side to atmosphere. A spring positioning plunger o may be provided on the valve h, and a spring stop for the handle. In the dotted line position of the handle j shown in Fig. 2, the exhausting pump is working at full speed to exhaust the train pipe and also the locomotive pipe past the valve g. When the handle is moved to the running position E, the speed of the exhauster is reduced. In the position F atmospheric air is admitted to the train pipe b only. When the handle is moved between F and G the driving motors of the locomotive are cut out of the power circuit, and in the position G atmospheric air is admitted to both the train pipe b and the locomotive pipe c to effect a complete application of the brakes. The electric switch gear controlling the vacuum pump, and the motors of the locomotive may be connected to the lower end q of the valve stem i.

As described, the auxiliary signals HL and HR are fed via delays 76, 78 so that the control signal SN is only blocked after the auxiliary signals have existed for a predetermined length of time. The delayed signals are fed together with signals w, -w to AND gates 73, 74, the outputs of which are connected via a NOR gate 81 to AND gate 83. If either AND gate 73 or 74 is enabled, NOR gate 81 delivers a "0" output to inhibit AND gate 83 and hence in inhibit signal SN. If negative signals HR and HL are used, the gates 73, 74, 81 are replaced by NAND gates.

Filed: 1969-05-27
Abstract: 1277082 Impedance converters PURDUE RESEARCH FOUNDATION 27 May 1969 [27 May 1968] 20454/69 Heading H3U [Also in Division G4] In order to obtain a desired non-linear characteristic, a non-linear element is connected to one of the ports of a two-port network which scales the characteristic of the element. Three possible types of such network ("scalors") are shown in Fig. 1 where the necessary transformations are set forth and the realization shown in schematic form. In the latter, diamonds represent sources controlled by one of the input variables I or V, an arrow distinguishing a current source and a  sign a voltage source. It can be seen that the effect of the networks is to expand either the voltage or current axes, or both and hence to re-shape the characteristic I-V curve of a non- linear resistor connected to the input port. The modified characteristic is available at the other port. Figs 2 and 3 show, respectively, practical voltage and current scalors. The scalors can also be used to scale the #-I curve of an inductor or the Q-V curve of a capacitor. The current and voltage sources comprise standard operational amplifiers.
