Title: Fast time constant circuit with clipping diode
IPC: G01S7/292
Filed: 1951-02-19
Abstract: 709,275. Radar. GILFILLAN BROS., Inc. Feb. 19, 1951 [Aug. 28, 1950], No. 4031/51. Class 40 (7) A pulse radar receiver includes a circuit having a relatively short time constant of one half or less than one half of the duration of the desired signal to differentiate and transform each of the received signals into two peaked signals of opposite polarity and means for eliminating, by clipping, those peaked signals which have a polarity opposite to that of the peaked desired signals. This arrangement enables desired signals to be indicated, for example, on a cathode ray tube, which would otherwise be masked by interfering clutter signals of relatively long duration. In one embodiment the receiver I.F. signals are detected by diode 20 and pulse signals such as wanted pulse 29 and undesired longer pulse 39 fed by switch 30 either directly to amplifier 32 feeding the indicator or to a unit 34 containing the short time constant circuit. If the detector output is applied to terminal 30B the pulses 29 and 39 are differentiated by the network 35, 36 so that each pulse is reduced to a short peaked signal of one polarity at the beginning of the pulse and a similar signal of opposite polarity at the end. Usually only the peaked signals corresponding to the beginning of the pulses are effective to operate the indicator and according to the invention the pulses of opposite polarity are removed by clipper 41. It is explained with reference to Figs. 3A, 3B and 3C (not shown) that wanted pulses can be indicated whether occuring at the middle or near the beginning or end of an unwanted pulse. The clipper is of particular value when the wanted pulse immediately follows the end of an unwanted pulse and the circuit would not otherwise recover in time to pass the peaked signal corresponding to the beginning of the wanted pulse. A more complex clipping arrangement using a crystal detector in a circuit between the grid and anode of valve 32 is described with reference to Fig. 4 (not shown). Specification 596,515 is referred to.

Filed: 1950-02-23
Abstract: 682,368. Centrifugal governors. STANDARD TELEPHONES & CABLES, Ltd. (Bell Telephone Manufacturing Co. Soc. Anon). Feb. 23, 1951, No. 4467/51. Class 57 [Also in Group XXXIV] A governor, e.g..for.a telephone dial, comprising a bracket fixed to a spindle, a plurality of pivots symmetrically . mounted on the bracket, an outer housing, a plurality of weights each engaging at one end a pivot and displaceable away from the spindle into engagement with the housing by the centrifugal forces generated by rotation of the spindle, means for applying a restoring force to the weights, and means for adjusting the restoring force is characterised in that said adjusting means comprises a member mounted on the spindle in pressing engagement with, and angularly adjustable with respect to, the bracket; that a plurality of coiled springs are mounted on the pivots and each provided with two arms, the end of one of which engages a well defined point on a weight and the end of the other of which engages the adjustable member at a distance from the spindle which is defined by the angular position of the adjustable member with respect to the bracket; and that during operation of the governor the adjustable member rotates as one with the bracket but when the governor is stationary, can be manually rotated relatively thereto while still in pressing engagement therewith, thereby changing the position at which the springs engage the adjustable member consequently changing the magnitude of the restoring force exerted by the springs and the speed of rotation of the governor at which the weights engage the housing. In the embodiment shown a spindle 1 is rigidly attached to a bracket 9 and a driving gear wheel 3. Two weights 4, 41 are mounted on pivots 5, 5<SP>1</SP> respectively and have fibre portions 19, 19<SP>1</SP> arranged to contact the inner surface of the housing (not shown) when the centrifugal forces overcome the restoring forces of springs 6; 61. An adjusting member 12 is held in pressing engagement with a member 11 attached to the bracket 9. The angular position of member 12 relative to member 11 can be adjusted manually, a locating tooth 13 engaging a rack 14 on member 11. This adjusting member allows a variation of the position at which it is engaged by the spring arms 23, 23<SP>1</SP> and consequent variation of the restoring force exerted by the springs. The speed of rotation of the governor is thus readily controlled.

Abstract: 779,374. Mixing - machines. VSCHP, VYZKUMNY USTAV STROJU CHLADICICH A POTRAVINARSKY.CH, and BARCOK, L. Feb. 18, 1955 [Feb. 27, 1954; Nov. 6, 1954], No. 4929/55. Class 86 [Also in Group VI] Dough is made by mixing predetermined batches of raw materials and feeding predetermined quantities of the mixture into at least one fermentation vessel where the mass previously fed to this vessel is propelled forward by this additional mass while it ferments and matures. The mixing vessel 1 has a rotary beater 3 with vanes 9 of plough share formation mounted on arms 10 secured to a driven shaft 8. Vanes of this shape agitated near the surface of the mass agitate it violently leaving the remainder almost at rest. Either vessel 1 or beater 3 or both vessel 1 and beater 3 are movable axially. In operation a slide 5 closes the outlet orifice 4 of vessel 1 which vessel is then supplied either in batches or continuously with flour and water and any other necessary ingredients. Initially beater 3 is in its lowest position relative to vessel 1 and, as the mass rises the beater or the vessel is so moved that the vanes revolve closely under the surface of the mass. When the predetermined quantity of the mass to be treated is present in the vessel, the beater is retained in position just below the level of the top of the mass. Discharge orifice 4 is then opened so as to allow the mass to flow into the inlet portions 6 of the fermentation vessel immediately below at the same rate as raw materials are supplied to vessel 1. The mass added to portion 6 pushes the mass already in portion 6 through to portion 7 and thus expels some of the mass from the portion 7. Instead of the slide 5, a pump may be used. In a modification, Fig. 4 (not shown) a series of stages may be provided each similar to the one described above. In a further modification, Fig. 5, leaven is beaten with water in beating bowl 19 and discharged through closing valve 20 into beating vessel 21 to which flour is supplied from apparatus 22. The mass from vessel 1 flows into distributer 23 where it is divided into two portions going to fermentation vessels 26 and 27 respectivelly. A gas cushion is formed in the inlet portion of each vessel which exerts a pressure on the mass in the vessel which may be decreased and increased by relief valves 29 and compressed gas supplied through tubes 28 so that the time taken by the masses to pass through the vesels is controlled. The contents of vessel 26 are returned to beating bowl 19 as leaven and the mass from vessel 27 flows into beating vessel 30, where it is whipped with water, salt solution and other ingredients and then passes to a kneading bowl 33 to which flour is supplied from apparatus 32. The mass finally passes to vessel 34 for further treatment.
