Title: Improvements in transmission systems and transmitters and receivers therefor
IPC: H04B1/02
Filed: 1962-02-27
Abstract: 952,033. Radio signalling; radio receivers &c. SIEMENS & HALSKE A.G. Feb. 27, 1962 [Feb. 28, 1961], No. 7702/62. Heading H4L. In a transmission system in which a main carrier is modulated by a band of frequencies, an auxiliary carrier which is modulated in a manner representing the frequency difference between the main carrier and auxiliary carrier is transmitted in a frequency band outside that occupied by the sidebands due to the said band of frequencies. At the receiver the auxiliary carrier and its modulation are combined so as to reconstitute the main carrier and the reconstituted main carrier is used for demodulation purposes. At the transmitter, Fig. 2, the auxiliary carrier frequency is generated at 6 and supplied via a phase adjuster 7 to a frequency divider of ratio 1/n=<SP>1</SP>/32. The output of the frequency divider is frequency multiplied by n - 1 at 9 and is also supplied to a frequency divider 11 of ratio <SP>1</SP>/ m =<SP>1</SP>/ 10 . The (n-1)th harmonic is amplified at 12 and fed to a ring modulator 1 which also receives the baseband signal for transmission, and the output is supplied via sideband filter 2 to frequency-changers 4 and 5 providing the required transmitting frequency. The output of oscillator 6 is modulated at 13 with the frequency divided signal <SP>1</SP>/ m  and fed to the common output 3. Supervisory signals also may be fed in at 14 to the modulator 13. After frequency-changing at the receiver, Fig. 3, the incoming signal is fed to a terminal 3<SP>1</SP> and a filter 15 selects the auxiliary carrier with its characteristic modulation. After amplification at 16 the auxiliary carrier is fed to a demodulator 18, the supervisory signal being selected at 20 and fed to an output 21 and also used via terminal 22 for gain control. The characteristic modulation is selected at 23 and multiplied by m=10 at 24 and fed to a frequency-changer 27. A narrow band filter 19 supplies the auxiliary carrier frequency via a phase adjuster 26 to the frequencychanger 27 and the difference frequency, which equals the main carrier frequency, is passed via a filter 28 and amplifier 29 to a demodulator 30. The received signal also is supplied via a filter 31 to the demodulator 30 which provides at its output the baseband signal.

Abstract: 1,148,422. Pneumatic despatch apparatus. SIEMENS A.G. 20 Feb., 1967 [21 Feb., 1966; 9 March, 1966], No. 7904/67. Heading B8A. A pneumatic pipe-line conveyer system is provided with stations each of which can serve selectively as a despatching, receiving or intermediate station. In the embodiment shown in Fig. 1, the housing 1a is provided with aligned conveyer pipe connections 2a, 3a, an inlet aperture 11a and a receiving chamber 14a. Within the housing there are mounted on a spindle 8a two pipes 4a, 5a and two deflectors 6a, 7a. In the position shown, a carrier arriving through the pipe connection 2a or 3a passes through the pipe 5a unhindered. To insert a carrier into the pipe-line it is placed in the pipe 4a and the spindle 8a is then rotated through 180 degrees to align the pipe 4a with the pipe connections 2a, 3a. When the spindle 8a is rotated through 90 degrees to bring one of the deflectors 6a, 7a between the pipe connections 2a, 3a, Fig. 2 (not shown), an incoming carrier is deflected downwardly, hits a buffer 12a or 13a and falls into the chamber 14a. In a second embodiment, Fig. 3B, the pipes 4a, 5a, the deflectors 6a, 7a and the spindle 8a of the previous embodiment are replaced by a plate 8b which supports a tubular member 14b consisting of two half shells 23, 24, pivoted to the plate 8b at 25, 26, and a deflector 15b, and which is movable along a spindle 13b and a guide 10b. In the position shown, the tubular member 14b is aligned with the pipe connections in the housing wall to allow free passage of a carrier. A carrier 17 to be despatched is inserted through the aperture in the housing and rests on flanges 21, 22 on the half shells 23, 24, as shown. The plate 8b is then raised until ribs 19, 20 on the housing force the carrier into the tubular member 14b, the half shells 23, 24 being forced apart about the pivots 25, 26 against the action of springs. The plate 8b is then lowered to return the tubular member to the position shown in alignment with the pipe connections. To receive a carrier, the plate 8b is raised to bring the deflector 15b between the pipe connections, the arriving carrier then being deflected downwardly through a flap 16b. The stations may be mounted in vertically extending conveyer pipe-lines.

Abstract: 1,100,942. Valves. ELECTRICITE MECANIQUE ET APPLICATIONS. 24 Feb., 1965 [28 Feb., 1964], No. 7980/65. Heading F2V. A check-valve 1 controlling flow between a chamber 35 having an inlet 2 and a chamber 34 having an outlet 3 is adapted to be held open to permit flow in the opposite direction. To permit such latter flow, a solenoid (not shown), is energized to depress a plunger 27 to rotate a lever 26 pivotally mounted at 29, the lever carrying adjustable tappets 31, 32 which engage respectively a push-rod 22 engaging a check-valve 19, and a valve member 25 guided in a bore 17 and loaded by a spring 24. Rotation of the lever first causes valve member 25 to obstruct communication between passage 17 and chamber 18, and then opens check-valve 19 to allow fluid from chamber 34 to flow via passages 4, 12, 16 and 13 to a space 6 in a chamber 36 containing a piston 8 having a longer effective area than valve 1 and connected to valve 1 by a push-rod 9, thereby moving the piston to open the valve. When the solenoid is de-energized, the plunger retracts, check valve 19 closes, valve member 25 rises under the action of spring 24 and the main valve 1 closes under the action of spring 10, the fluid behind the piston being exhausted via passages 13, 17, 14, 38 and 39. The plunger 27 may alternatively be actuated mechanically or pneumatically.

Title: Improvements in and relating to control mechanisms for dual fuel internal combustion engines
Inventor: MITCHELL CALLUM BLACK
IPC: F02D19/10
Filed: 1959-03-10
Abstract: 869,906. Engines using alternative fuels; regulating. ENGLISH ELECTRIC CO. Ltd. March 2, 1960 [March 10, 1959], No. 8213/59. Classes 7(2) and 7(6). In a mechanism for connecting a shaft A, Fig. 1, of a speed governor to the fuel metering linkage of a dual-fuel engine, the crank-arm B carries on its crank-pin a freely rotatable control member D having two bearings E1, Al spaced from the crank-pin C by the same distance as the throw of the crank arm B, bearing Al controlling the liquid fuel supply and bearing E1 controlling the gas and air metering valves, and the axis of the bearing not in use being brought into line with the axis of the shaft A. The gas metering valve driving shaft M is spring-loaded, as far as allowed by a variable stop Q, to the opened position of its valve and the air metering valve driving shaft S is spring- loaded to the closed position of its valve, both in the directions of the arrows, and the shaft Z controls the liquid fuel pump racks. For controlling the gas fuel without control of the liquid fuel the bearing Al is in line with the shaft A as shown in full lines and movement of the crank arm B rotates bearing El about the axis of bearing A1 to push, through a linkage K, K2, Kl a pin L2 of a freely pivoted lever L against a fixed dog L1 on the shaft M. Simultaneously, a lever P, freely rotatable on the shaft S and which carries an adjustable stop O, is rotated by engagement of a variable ratio radius arm N, in the slots of levers L, P, the stop O acting one one arm of a two-armed dog P1, fixed to the shaft S. The other arm of the dog PI co-operates with a pin R1 of a lever R freely rotatable on the shaft S, which is connected by linkage T, E to the bearing El. On the bearing A1 a telescopic member U is connected to the shaft Z through a lever V. Movement of the control member D into the position D1 shown in chain dotted lines causes the rod T through pin R1 and dog P1 to set the shaft S in an optimum position for liquid fuel operation air supply whilst rendering the control of shaft M inoperative and the control of shaft Z operative, due to the alignment of the shaft A with the bearing E1. An intermediate setting of the control member D allows operation on mixed fuels. A control device G, more fully shown in Fig. 2, changes fuel supply from gas to liquid fuel automatically and from liquid fuel to gas through manual operation of the lever H. With a failure of gas fuel supply the centre E1 moves upward to admit more gas fuel and the bar E abuts a stop F1 to raise a member F against a spring d. This disengages member F from a stop J and the spring-loaded plunger a moves the member F to the right to turn the control member D into the position D1. Manual release of the member F can be effected by depressing a lever g and resetting of the member F is effected by the lever H.

Abstract: 798,363. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 16, 1956 [March 19, 1955], No. 8318/56. Class 40 (3). In a colour television picture reproducing device in which component colour images produced by at least two cathode-ray tubes are combined optically to form a composite colour picture the image signals modulating the electron beam of each tube having different band widths the tube to which the signals of greater bandwidth are applied is selected to have a smaller control electrode aperture than the tube or tubes to which signals of lesser band width are applied. By this means the " fineness of focusing " on the screen is made sufficient only for the particular definition (band width) to be reproduced with a consequent reduction in the specific cathode current load and therefore an increase in the life of the tubes. By having the control electrodes of all tubes at predetermined distances from the cathode (depending on the particular aperture) the cut-off voltage of each tube may be equalized.
