Title: Improvements in or relating to frequency shift telegraph receivers
IPC: H04L27/16
Filed: 1952-09-23
Abstract: 699,729. Automatic frequency control systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Sept. 23, 1952 [Feb. 14, 1952], No. 23861/52. Class 38 (iv). Frequency drift in a frequency-shift telegraph system employing heterodyne reception is compensated by applying the two reduced frequencies f<SP>1</SP> f<SP>2</SP> in parallel to two similar discriminators D\ D<SP>2</SP>, each centred on the mean of the two desired values of f<SP>1</SP> and f<SP>2</SP>. Both the A.C. and the D.C. output are taken from one discriminator D<SP>1</SP> and only the A.C. output is taken from the other, D<SP>2</SP>. The two outputs are differentially combined to provide a D.C. voltage u for controlling at BP the frequency of the local oscillator O. The received waves are amplified at V and mixed at M with the output of the local oscillator O to provide the reduced frequencies f<SP>1</SP>, f<SP>2</SP> which may be in the audio range. These are passed through an amplifier Z and limiter B to the similar frequency discriminators D\ D<SP>2</SP>. Both the A.C. and the slowly-varying D.C. output are taken from the discriminator D', and may be passed to the signal-receiving circuits F, eg. a teleprinter. A network C,R suppresses the slowly-varying output from the discriminator D<SP>2</SP>. The two outputs are so combined in series that the A.C. output is suppressed, and the slowly-varying D.C. output representing the tuning error is fed back as a control voltage u to a reactance valve or other frequency controller BP associated with the local oscillator O. When signalling ceases and only one of the two frequencies is transmitted, the existing setting of the local oscillator frequency is maintained by connecting a steady voltage (which may be adjustable by a potential divider P connected to a source Q) across the resistor R to neutralize the steady voltage output from the discriminator D<SP>1</SP>. The source Q and divider P are switched in by a delayed-action relay Re which is operated by connection to the signal-receiving circuits.

Title: Improvements in or relating to a fluid flow regulating device
Inventor: TAUSCHER VERNON ARTHUR
IPC: F15B13/043
Filed: 1953-08-29
Abstract: 756,442. Valves controlled by auxiliary valves. NORTH AMERICAN AVIATION, Inc. Aug. 29, 1953, No. 23950/53. Class 135. A fluid flow regulating device comprises means causing flow from a common source through restriction means into a pair of parallel channels, a T-shaped junction for recombining the flows into a single channel, valve means at the junction controlling the flow from each of the pair of channels, and means responsive to the differential pressure between the channels for regulating flow in a hydraulic system substantially linearly with respect to a major part of the motion of an actuating means for the valve means. Pressure fluid passes via inlet 2, passages 22, 21 and restrictions 28, 29 in pistons 37, 38 at the ends of hydraulic valve 9, to passages 17, 19 having their junction with an exhaust passage 18, 23, 4 controlled by the central land 25 of a solenoid-operated pilot valve which has a negative lap at the T-junction where passage 18 enters pilot valve cylinder 24. An increase or decrease in current through solenoid 16 causes the armature 12 carried by diaphragm springs 13, 14 to move the pilot valve so that pressure builds up in one of the piston chambers 41, 42 and shifts the hydraulic valve lands 39, 40 to supply or exhaust fluid through the ports 3, 5. The springs 13, 14 are so chosen that the displacement of the pilot valve is proportional to the current in the solenoid and the flow through valve 9 is shown to be substantially linear within limits to the solenoid current. The pilot valve is balanced with respect to exhaust pressure which acts on the end lands 35, 36 via passages 33, 20, 34 and 32, and is unaffected by the pressure differential in the passages 17, 19. The restrictions may be in the casing leading from passages 21, 22 to chambers 42, 41. The fluid source may be connected at 4 and the exhaust at 2.

The machine which may be used for waxing, polishing or shaving a floor, according to the nature of the brush, comprises a housing 1 for the electric motor 2, 3, the vertical shaft 4 of which carries an eccentric peg 7 mounted in a bearing 8 carrier in the generally rectangular-shaped plate 9. A rearward extension 9a of the plate 9 is connected at 10 to, and centrally between, two springs 12, the outer ends of which are connected to attachments 11 on the housing 1. A generally rectangular-shaped brush is resiliently and detachably mounted on the plate 9, Fig. 2, by pegs 92 on the plate engaging in rubber sockets 93 on the brush backing. Rubber pegs 94 on the back of the brush also engage the underside of the plate 9. The handle 16 of the machine is connected to a socket 14 detachably carrier or the housing 1 by a screw 15. A downwardly bent portion of the handle may be provided with a roller or sliding shoe to be engageable with the floor surface and the roller or shoe may be adjustable for height on the handle. The handle shown may, in a modification, be replaced by a handle in the form of a vacuum cleaner, whereby dirt may be sucked from the floor. Owing to the resilient connection of the plate extension 9a with the housing 1 at 10, any point on the brush performs an elliptical orbital movement. In the modified embodiment shown in Fig. 12, the driving plate 109 is resiliently connected to the housing 1 by two pairs of springs 112, 212 the outer ends of the springs being connected at 111, 211 respectively to the housing. In a further modification two brushes 13 are carried by the drive plate and arranged parallel to each other on opposite sides of the motor shaft.

Filed: 1937-09-03
Abstract: 501,756. Mercury switches. CIANCHI, A. Sept. 3, 1937, No. 24149. [Class 38 (v)] An electromagnetically or magnetically-operated mercury or like switch with a slow make and a slow break comprises a container 1 and a float 4 carrying an armature 5, the float being hollow and containing mercury which communicates with mercury in the container through a small hole 8. In the position shown, circuit between electrodes 2 and 7 is broken. On energization of a coil 6 the float which slides on the electrode 7, is pulled down, causing the mercury in the container 1 to rise and start flowing through the hole 8. After a time interval levels outside and inside the float 4 become equalized and the electrode 7 is engaged by the mercury to close the circuit 2, 7. On de-energization of the coil 6, the float rises, and mercury begins to flow out of the float through the hole 8, but circuit is not broken till the mercury in the float has dropped sufficiently to clear the electrode 7. The flow continues till the mercury levels are again equal and the parts in their original position. By connecting the electrodes 2, 7 as shown by dotted lines, the switch becomes a continuous interrupter, completion of the circuit between the electrodes 2, 7 serving to short circuit the coil 6. Specification 497,323 is referred to.

Title: Improvements in or relating to telecommunication systems
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04M11/06
Filed: 1964-06-11
Abstract: 1,039,664. Line transmission systems. STANDARD TELEPHONES & CABLES Ltd. June 11, 1964, No. 24248/64. Heading H4R In a telecommunication system a speech channel 1 (Fig. 1) is terminated by a recording head 2 co-operating with a delay device 3 such as a rotating magnetic drum, a magnetic disc or magnetic tape loop. Speech recorded on the delay device 3 is read out by a head 4 and fed to a channel 7, after a delay preferably exceeding 100 milliseconds. Channel 1 is also connected to a detector 8 for detecting periods of silence in incoming speech. The detector output is fed as a stepped waveform to a timing and control circuit 9. This has two timing circuits. The first produces an output which lasts for a period equivalent to the delay of device 3 and commences when a speech burst begins. The second produces an output which also lasts for a period equal to the delay but starts when the speech burst ends. When a period of silence occurs in the incoming circuit the second timing circuit is started. If the period of silence is still present at the end of the timing period a switch 6 is operated changing channel 7 from link 5 to a data store 10. Circuit 9 also initiates transmission of data from store 10. When the silence in incoming speech ends, the silence ends on link 5 at a later time equal to the delay. The first timing circuit output switches the outgoing channel 7 back to the link 5 as the delayed period of silence ends and it also stops the transmission of data from store 10. The timing periods may be slightly altered to obviate undue clipping. Supervisory signals to advise the receiver of changeover are controlled by the two timing circuits. The magnetic drum may carry several tracks for use with several channels. The outgoing channel may serve more than one data source, the control circuit being arranged to connect the channel to the data sources one at a time on a priority basis. A 4-wire " Go " and " Return " system may be arranged so that a conversation and two data messages can be handled together.
