Abstract: 1,002,032. Frequency analysers. E. A. NEWMAN, D. V. BLAKE, and J. S. APPLEBY. May 2, 1962 [May 5, 1961]:No. 16430/61. Heading G1U. A signal to be frequency-analysed is applied to a terminal 11 of a delay line (Fig. 1) and the voltages at each mutually-opposed pair of a plurality of monitoring points e.g. A 1 , A 2 , are multiplied together by individual voltages-multipliers (Fig. 2) to determine the degrees of auto-correlation between oscillations at said points. The applied signal is delayed between mutually-opposed points  during time intervals equal to the periodic times of the harmonic components the delay between points A 1 , A g  adjacent the ends of the line being equal to the periodic time of the harmonic of lowest frequency. Each voltage multiplier comprises a pentode valve V, having a short suppressorgrid characteristic and which governs a gas-filled triode valve V 2  whose glow-intensity indicates the voltage product. The valves V 2  in the voltagemultipliers may be disposed in a linear array (not shown) such that the frequency components of the applied signal are displayed by the valves having maximum brightness and may be photographed, each valve reaching maximum brightness when the corresponding harmonic is present and the oscillations at the associated monitoring points are inphase with one another. Alternatively, visual indicator tubes of the "Magic Eye" type, or galvanometers, may be used in place of valves V 2 . The voltages at the mutually-opposed points may be divided by one another by individual voltage dividing circuits (not shown), or they may be combined with one another in some other non-linear manner e.g. by individual phase sensitive detectors, instead of being multiplied together. The signal may alternatively, be applied to a diaphragm 16 (Fig. 3) at one end of an acoustic delay line 17, transducers T 1 ----T 6  being provided at mutually-opposed monitoring points and connected to individual voltage-multipliers M 1 , M 2 , M3, respectively. The line 17 may be a tube filled with solid, liquid or gaseous material, reflections being prevented by sound absorbing material 18. The transducers may be of the piezo-electric type.

Abstract: 1,229,599. Tractor power lift mechanisms. CAM GEARS (LUTON) Ltd. 25 June, 1968 [28 June, 1967], No. 30140/68. Divided out of 1,218,552. Heading A1P. [Also in Divisions B8H and F2V] A spool valve for controlling a single acting ram in a tractor power lift mechanism has pressure inlet 35A, exhaust 35B and ram duct 36. An internal chamber 32 of the spool is closed at one end by a non- return valve 33 biased by spring 33B against seat 34. As shown, the valve is in its neutral position. Movement of the spool to the right closes the exhaust duct so that pressure builds up in chamber 32 to open valve 33 and supply fluid to the ram. Movement of the spool to the left causes valve 33 to engage abutments on the housing and thus open to connect the ram to exhaust. An adjustable stop 43 limits such movement whereby the rate of exhaust of fluid can be controlled. In an embodiment an overload release duct operating on excessive movement of the spool is incorporated. In the embodiment shown in Fig. 3A the spool is biased by spring 50. Movement of the spool to the left blocks off the exhaust duct 35B so that pressure fluid opens valve 33 to supply the ram via duct 52. Movement of the spool to the right opens valve 33 and connects ram to exhaust. This movement is limited by manually adjustable stop 56. Overload caused by excessive movement of the valve to the left causes the ram to be connected to exhaust through duct 53. In further embodiments the biasing spring 50 is double acting and the non- return valve 33 is formed by a ball valve associated either with the spool- or the valve body. In another type of valve (Fig. 7, not shown) a non return ball valve, which is manually operable, is incorporated in the ram duct to control the exhaust of the ram.

Abstract: 1,230,054. Telephone exchange equipment; transistor switching circuits. MARCONI CO. Ltd. 19 Jan., 1970 [8 April, 1969], No. 2456/70. Headings H3T and H4K. Current taken from exchange battery terminal 2 to one leg 1 of an exchange line is fed over a first switch (transistors 3, 4), a second switch (diode 8) operating when current is drawn above a certain value so as to introduce feedback dependent on direct current in the line but substantially independent of speech components on account of the capacitor 7 shunting the resistor 6 across which the voltage to operate the second switch 8 is developed. The point at which feedback is switched in by diode 8 is set by divider 10, 11, and an auxiliary bias source. A transistor 9 is switched with diode 8 to give a low impedance shunt for the base of transistor 3. The transistors 3, 4 are of opposite type to compensate for temperature variation. By adjusting the current at which feedback becomes operative to a value below the holding current of a connection, establishment of a connection can be effected at a speed which is not retarded by the time constant of the feedback circuit. If the current at which feedback becomes operative is less than twice the holding current, the presence of feedback allows short duration tests to be made without fear of setting up double connections.

Abstract: 1,232,028. Making valve bags. CANADIAN INDUSTRIES Ltd. 5 Aug., 1968 [21 Aug., 1967], No. 38464/67. Heading B5D. In a machine for making valve bags such as disclosed in Specification 1,211,696 a folded web 16, Fig. 8, of heat-sealable plastics film has overlapping valve panels 21 sealed along the open edges at 17 and 26 to form a tube. Gussets are formed at the sides of the tube by wheels 27, 28, 30 and V-shaped and transverse seals made. The plastics web is advanced in units of one bag width by drive rollers 33 which are governed by a photo-electric cell responding to marks printed on the film web. The tube is then cut into separate bags. Alternatively the machine can be arranged to form pillow-type bags. Valve panel insertion.-Film from reel 19, Fig. 10, overlaps thinner film from reel 18 at roller 43 and both pass through a sealing device 20 to join them at the overlap. The sealer 20 consists of a heat sealing element 45 which acts against an anvil attached to plate 50 and is activated by an air piston and cylinder 48 acting against springs 49. The sealed film passes between metering rollers 51, 52, each of which mesh together by spur gears 57, 58, Fig. 12, and are rotatably mounted on freely rotating shaft 53 and fixed shaft 54 respectively by unidirectional clutches 83, 84. The draft 53 is driven by a pinion 76 and rack 75 the extremity of which carries a rod 80 and adjustable collar 81 coacting with stop 82 to limit the throw of the rack 75 and thus meter the plastics film. The rack 75 is activated by air cylinder 77. Each end of shaft 53 carries spur gears 59 which engage racks 60 sliding in guide 61 to advance a film support plate 62 when the metering rollers discharge a length of valve panel. The film then advances between clamping element 63 and cutting member 65 until the edge lies over the anvil 86 and underneath the edge of the lower layer of the web 16 and the trailing edge of the preceeding valve panel 21. The leading edge of the valve panel is then heat sealed to the edge of the lower ply web 16 by element 87 acting against the anvil 86 and actuated by air cylinders 92, 93 through the frame 88. Air cylinder 67 clamps member 63 against the cutting member 65 and air cylinder 74 actuates a knife 70 to cut off the panel to the required length. The web 16 is advanced and a folding device 24, Fig. 8, folds the valve panel 21 over the upper layer of the web 16, to be heat sealed thereto at 25 by element 26 acting on former plate 22.
