IPC: G01J3/42
Filed: 1965-08-25
Abstract: 1,122,215. Photo-electric systems. INSTITUT FUR REGELUNGSTECHNIK. Aug. 25, 1965, No.36521/65. Heading G1A. In an arrangement for measuring the intensity of a fluctuating light flux relative to a comparison flux fluctuating in phase therewith by directing them on to separate photo-cells and controlling an attenuator in the comparison flux path to equalize the fluxes, the sensitivities of the photocells are equalized by directing light on to both photo-cells that has been chopped at a frequency V2 (>V1, the frequency of the fluctuating light) and adjusting the anode voltage of one cell until the outputs of the cells at V2 is zero. In an embodiment for measuring the absorption of a liquid, light from a metal-vapour lamp energized with A. C. or pulsating D.C. is split to provide the measurement and comparison fluxes. The sensitivity correcting light beams are derived from the same source.

Abstract: 800,543. Weft replenishing looms. RENSHAW, G. A. Dec. 12, 1955 [Dec. 17, 1954], No. 36557/54. Class 142(2) The shuttle boxes are arranged one above the other, but each box is displaced horizontally from the preceding box so that a full bobbin can be inserted into any box from above. The boxes 10-13 slide in guides 48, 49 and are moved by a member 50 operated by cams or a dobby. The magazine has compartments 56-59 and is controlled by any known colour selecting mechanism which releases a bobbin of the required colour to a conveyer 62. When a weft feeler indicates that a shuttle requires replenishing a dagger is raised and strikes an abutment on the stay at the next beat-up. The inserter 71 is subsequently pivoted and the conveyer also tilts and the released bobbin rolls down until it is held by a lip 90 and a pin 110. Further movement of the inserter forces the bobbin into the shuttle. If the shuttle box fouls the conveyer, the conveyer will swing forwardly about a pin 77. Each box has a swell 32 (Fig. 2) loaded by a spring 36. The "free"end of the swell is retained by a screw and nut 44.

Title: Apparatus for controlling television signals
IPC: H04N5/272
Filed: 1959-11-05
Abstract: 886,086. Television. FERNSEH G.m.b.H. Nov. 5, 1959 [Nov. 5, 1958], No. 37636/59. Drawings to Specification. Class 40(3). Relates to apparatus for controlling television signals comprising means for applying television signals from each of two television scanners to a combining circuit by way of gate circuits which are opened alternately by the action of a keying signal produced by scanning a master pattern by means of a third television scanner. The signal from the combining circuit represents a composite image in which the scene viewed by the first of two scanners is replaced by the scene viewed by the second of the two scanners over an area determined by the master pattern scanned by the third scanner. In the apparatus, means are' provided for varying the phase and/or duration of the keying signal relative to the gated television signals, in order to permit the position and/or size of the area to be adjusted, by changing the position or size of the scanning raster in the third scanner. The relative, size of the horizontal and vertical scans is also made adjustable to permit the aspect ratio of the area to be adjusted. When the scan amplitudes are increased above normal so as to overscan the area of the target in a pick-up tube employed as the third scanner, there is a tendency for the scanner to develop spurious signals. In accordance with' the invention these : are eliminated by a blanking system, Fig. 5 (not shown), which generates line and frame frequency pulses coincident with the scanning of the target and functions either to blank the tube beam except when it is traversing the target or to suppress the tube output signal except when the target is scanned. As an alternative the pickup tube may incorporate a frame electrode surrounding the target which engages the beam whenever it overscans the target and is held at a suitable potential to prevent the production of spurious signals. As an alternative to varying the area size by variation of raster size, the size of the image of the master pattern presented to the third scanner may be varied either by varying the distance of the pattern from the scanner or by use of a lens system of variable magnification. Reference is made to the rotation of the area, this being brought about either by rotating the pattern in a plane perpendicular to the optical axis of the third scanner, or by the use in the scanner of a pick-up tube including an image section in which the electron image may be rotated. Preferably a number of different master patterns may' be provided which may be carried by suitable members to permit their introduction into the optical path of the third scanner' when required. Provision is made to introduce reference level pulses into the keying signal during the blanking intervals which function to set the trigger level of a phasesplitting stage which provides oppositely phased versions of the keying signal for control of the gate circuits in the signal paths from the first and second scanners.

Abstract: 1406678 Automatic control FORNEY INTERNATIONAL Inc 11 Aug 1972 [11 Aug 1971] 37641/72 Heading G3N [Also in Division F4] A control system for two banks of burners in a furnace comprises electronic summing circuits for providing signals respresentative of the number of burners in operation in each bank, comparator means for comparing the two signals, and control means including logic circuitry for controlling the number of burners in operation, in response to the overall load deinand. In the illustrated embodiment the burners are connected to an adder/ subtractor amplifier 80 which produces an output depending on the difference in the numbers of burners in operation in the two banks, electronic comparator circuits 92, 94 connected to AND gates 110, 114, 116 and 118 producing signal outputs responsive to the difference in the numbers of burners in operation in the two banks, and a control circuit 128 responsive to said output signals for controlling the burners. Each summing circuit comprises flame detectors (16), Fig. 2, (not shown), one for each burner (15), connected to the input circuits of transistor amplifiers, Fig. 4, (not shown) whose output circuits are connected to the differential amplifier 80 and in parallel with each other. This output is fed into the two comparators 92, 94 in which the voltage signal from the amplifier 80 is compared with voltages from a corresponding pair of two series of potentiometers 46, 48, in which each pair corresponds to a given value of the difference in the numbers of burners in operation. The output from the comparator circuits 92, 94 indicates which of the banks has a greater number of burners in operation and is fed, together with signals from a load control circuit 128, which indicates the overall heat demand, into the four AND gates 110, 114, 116 and 118 whose output controls two burner control circuits 142, 146. The control circuits 142, 146 restore the balance in the numbers of burners by lighting some in one bank if more heat is required or extinguishing some in the other bank if less heat is required, by operating valves V10, V10' in fuel-pipes P10, P10'. A D.C. source 20 provides power for all the active circuits and a Zener diode network 26 provides a voltage reference.
