Title: Amplification devices for amplifying variable width pass bands in radio electrical apparatus
IPC: H03F1/50
Filed: 1946-08-28
Abstract: 631,177. Valve circuits. HATTE, P. L. M. Aug. 28, 1946, No. 25725. Convention date, Oct. 11, 1944. [Classes 40 (v) and 40 (vi)] A H.F. amplifier comprising a high Q resonant circuit is given an effective wideband characteristic by continuously varying the point of resonance on either side of the mid-band position at a very high frequency. The Figure shows the application to the I.F. amplifier of a superheterodyne receiver. The incoming signals at antenna 1 are amplified in stage 2 and converted to the intermediate frequency in stage 3 the resonant frequency of this stage being determined by the high Q circuit comprising inductor 5 tuned by capacitor 6 in parallel with the input capacities of valves 9 and 7. Valve 9 is an I.F. amplifier stage beyond which point the circuit of the receiver may be conventional. The input capacity of valve 7 is varied continuously and very rapidly over a range by varying the suppressor grid potential by oscillator 12 so that the resonant point of the I.F. amplifier is rapidly varied over a considerable frequency range and the amplifier is thus given an effective wide-band characteristic, the band width of which may be varied by adjustment of the output amplitude of oscillator 12. An H.F. amplifier of this type may be used in a super-regenerative receiver in conjunction with a, number of normal amplifying stages the receiver tending to oscillate when the resonant frequency of the controlled stage passes through the resonant frequency which is common to the other stages. A wideband amplifier of this type may also be used for H.F. amplification in a television transmitter.

Abstract: 600,377. Wrapping-machinery. ROSE, A. G., GILBERT, J. A., and ROSE BROS. (GAINSBOROUGH), Ltd. Oct. 4, 1945, No. 25818. [Class 94(i)] A method of forming packages comprises folding a wrapper of paper, foil, film or other material in the form of a U about the bottom and two opposed sides of an article, with the upstanding portions of the wrapper parallel to the direction of travel of the article, pressing the upstanding portions together to form a longitudinal seam, which is then sealed and folded on to the article, turning the partially wrapped article through 90 degrees so that its ends lie parallel to its direction of travel, and collapsing and sealing end portions of the tube extending from the ends of the article to form lateral seams. Articles 11, Figs. 3 and 4, (Fig. 4 is a continuation of Fig. 3 to the right), are fed in succession to a series of open-ended pockets 12, a succession of heatscalable wrappers 14 being fed across the path of the articles so that each article carries with it into the pocket a wrapper which is thus folded in U-form about the article. Each pocket 12 is mounted for movement about a vertical axis on a guide block attached to a conveyer chain which is driven intermittently and carries each pocket in turn to a series of operating stations. Freely mounted on the base of each pocket is a pair of rollers 19, 21, the roller 19 engaging stationary guides 22. Each article is carried from the feeding station A to an intermediate station and thence to a first folding station B, the upstanding portions of the wrapper being brought together during the latter movement by a pair of folding members 26 into contact with a stationary web 27, forming a longitudinal seam. The article is then carried to a sealing station where the seam is sealed by pairs of heated rollers 28. The article is then brought to a turning station C, the roller 19 moving out of the guides 22 and the roller 21 engaging a fixed guide 29, rotating the pocket through 90 degrees and entering the guides 23. As the article leaves the turning station, the longitudinal seam is folded over the article by a stationary folder 31, and at a second folding station D pairs of spreader fingers 32 collapse the walls of the ends of the wrapper tube to form end seams which are completed by pairs of rotary folders 33 pivoting about the ends of the package in arcuate tracks 36. The seams are sealed by two sets of heated rollers 39, and at a delivery station E, lifting members 41 eject the article into a stacker disposed above the conveyer chassis, members associated with the stacker folding the end seams and tabs extending from the end of the package over on to the package. At a second turning station, the pockets are rotated into their usual position, and returned by the chains to the feeding station.

Abstract: 896,429. Grinding and polishing. GRUBB, K. T.,and GRUBB, B., [trading as STUERS CHEMISKE LABORATORIUM, H.]. Aug. 12, 1958 [Aug. 17, 1957], No. 25901/58. Class 60. [Also in Group XXXVI] A process for the wet grinding or polishing of surfaces comprises supplying liquid to the upper surface of an abrasive or polishing sheet 4, Fig. 1, which is placed so as to be freely displacable on a rotary supporting disc 1 having an elevated marginal portion 2, the liquid being supplied adjacent the axis of rotation of the disc. The sheet, which may be sandpaper, glasspaper, or a polishing cloth for use in electrolytic polishing, is placed on the disc and its edges, which, until such time as the sheet is soaked by the liquid such as water, alcohol or electrolyte, supplied from a pipe 5, may tend to lift from the disc, are retained in contact therewith by means of a ring 3 ; the sheet is freely displaceable relative to the disc and ring so that it can expand relative thereto. During rotation of the disc, the centrifugal action on the film of liquid between the sheet and disc has a suction effect on the sheet to hold it in position without bulging so that a plane surface is produced in a workpiece held on the sheet. The opposite poles of a source of voltage are applied to the disc and workpiece during electrolytic polishing. In other embodiments, the elevated portion of the disc may be undercut to act as the retaining ring, slots upwardly sloping from the surface of the disc permitting the removal of waste material, or the ring may be stationary and supported above the disc with a gap therebetween. In further embodiments, the ring 10, Fig. 3, may be supported on the elevated portion 6 by pegs 9, 12 and be spaced from the sheet to permit the liquid to flow between the disc and ring, or consist of an annular ring 15, Fig. 5, supported in the portion 17 by lugs 16. In order that workpieces of a size larger than that of the disc may be machined, a disc 20, Fig. 6, of a depth greater than the height of the elevated portion 21 is placed on the disc 1 and the sheet 22 placed on the disc 20 with its edges held down by a ring 23. The liquid may be formed into a ring during rotation of the disc and collected in a scoop to be fed back to the centre of the sheet.

Abstract: 704,370. Fluid-pressure servomotor-control systems. OTIS, H. C. Nov. 6, 1951 [Nov. 17, 1950], No. 25942/51. Class 135 A safety valve 9, Fig. 1, e.g. for a well-head 1, comprises a body 12, Fig. 3, with an inlet 13 and outlet 15, a tubular member 22 slidable in the body and carrying a closure member 16 tor co-operation with a seat 17 and a pressureresponsive member 29 which forms, with the member 22 and a seal 23, a chamber supplied with line fluid through an orifice 37 and adapted to be vented when a predetermined high or low pressure is reached in the chamber to cause member 16 to be seated. The closure member is held in open position by the pressure in the chamber plus a spring 44, and the chamber communicates with pilot valves connected to pipes 40, 41, Fig. 4, one opening at a predetermined high pressure and the other at a predetermined low pressure. Should either valve open due, e.g. to a blockage or leakage, respectively, in the outlet, inlet pressure seats the member 16, orifice 37 being then positioned downstream of seal 23 to prevent a continuous bleed of fluid through the open pilot valve. To move the member 16 to open position the open pilot valve is closed, and inlet pressure admitted to the chamber by opening a valve 46, which is closed once member 16 is unseated. In another arrangement, the orifice 37 is omitted and pressure fluid is supplied to the chamber through a line 71, Fig. 5, from a point 50 downstream of a throttle 10 connected to the outlet of the valve. When the closure member 57 is unseated, the pressure fluid passes through orifices 75, 76 to both sides of the pressure responsive member 77, but when one of the pilot valves opens, inlet pressure commences to move the member 57 towards its seat, and causes a ring 72 to cut off the orifices 75 whereby the pressure acting through orifices 76 aids in seating the closure member. U.S.A. Specification 2,566,772 is referred to.

Title: Improvements in or relating to aerial systems
IPC: H01Q11/04
Filed: 1929-08-27
Abstract: 318,112. Latour, M. Aug. 27, 1928, [Convention date]. Aerials; directive signalling. - Relates to a short-wave aerial comprising a horizontallyarranged continuous conductor bent to form alternate horizontal and vertical sections, all lying in one plane, and all acting as radiators. In order that such an aerial may radiate or receive in or from a direction making any desired angle x with its plane, it is designed in accordance with the formula h + x  x cos a = (2n + 1) #/2, where h and x are the respective lengths of the vertical and horizontal sections, # is the wave-length, and n is any integer. For maximum radiation in the plane of the aerial (a = o), the following values may be taken : n = o, h = #/4 and x = #/8. Another example giving a = o for all values of x, is n = o, h = #/2. If in the latter example x = h, then when # = 2h, maximum radiation is in the plane of the aerial; but by increase of the* wave-length the beam is swung away from the aerial plane, and when # = 4h is normal to that plane. A plurality of aerials may be arranged in parallel planes or in the same plane, or aerials as described may be combined with aerials which radiate in directions normal to their planes. Specification 272,117 is disclaimed.

Title: Improvements in rotary valves
IPC: F16K5/20
Filed: 1929-08-28
Abstract: 338,913. Schmidt, A., and Haselhorst, E. Aug. 28, 1929. Rotary spherical valves ; wedging or jamming.-Relates to rotary spherical valves of the type comprising a rotatable body on which are mounted valve plates which are withdrawn from their respective valve seatings in the initial part of the opening movement prior to the rotation of the said body. The arrangement of the valve comprises a bored spindle 7, 9 passing through a bored spherical body 15 which is coupled to the spindle 7, 9 for a part of the rotation of the spindle and to the casing during the remaining part of the movement. Valve plates 20, 21 are mounted in turned recesses on the spherical body 15 and these are radially displaced by eccentric parts of the spindle during the latter part of its rotation, the said valve plates being movable radially by the action of claws 27 formed on plates 23, 23', 24, 24' and eccentrics 11, 11<1>, 12, 12<1>, one of the said plates 23 having a projection 57 guided in a groove 51 in the casing and engaging, in one position, a shoulder 56 for the purpose of locking the plates while the eccentrics displace the valve plates. The device for locking the spherical body to the spindle and to the casing alternatively comprises a roller 50 engaging a groove 51 in the casing and operating, through levers 47, 48, a notched locking-bolt 41 to engage a corresponding recess in the collar 10<1> of the valve spindle and so lock the body 15 to the spindle. From the fully open position in Fig. G, an anticlockwise rotation of the spindle moves the spindle and spherical body together until, after a quarter turn, the roller 50 engages a recess 51 in the groove 52 of the casing and so disengages the spherical body from the spindle; further rotation of the spherical body is thereby prevented and hence the eccentrics press the valve plates tightly against their seats in a further quarter turn of the spindle, the valve being then fully closed. In the opening movement the reverse action takes place.
