Title: Improvements in or relating to coupling arrangements for resonant networks
IPC: H03H7/01
Filed: 1939-04-13
Abstract: 529,168. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BRAILSFORD, J. D. April 13, 1939, No. 11275. [Class 40 (v)] A high impedance source, e.g. a valve V1, feeds a variably tuned filter 1, the output of which is connected to the grid of valve V2. As the impedance of the D filter 1 rises with frequency, the gain from valve Vl to valve V2 would not be uniform with frequency. This non- uniformity is corrected by making the feed to the filter 1 through a condenser 2 in association with a resonant circuit 3, which is tuned to the lowest frequency of the filter 1. Further, in order that the circuit shall have a " Q " value proportional to frequency, the output side of the circuit 1 is connected to the valve V2 through a condenser 4 and circuit 5 which is tuned to the lowest frequency of the filter 1. These arrangements are shown in the Specification to be equivalent to feeding into and out of variable condenser taps on the filter 1. Specification 518,969 is referred to.

Title: Improvements in thread milling machines
IPC: B23G1/32
Filed: 1938-04-13
Abstract: 496,631. Thread - milling machines. PLOTTNER, W., and HILLE-WERKE AKT.- GES. April 13, 1938, No. 11421. [Class 83 (iii)] A planetary-type thread-milling machine wherein an annular ring cutter is moved axially through the pitch of the thread during the planetary movement has the cutter spindle mounted eccentrically in an inner sleeve which is itself eccentrically mounted in an outer sleeve, relative movement between the sleeves to determine the depth of cut being permitted by resilient means and co-operating projections on the two sleeves. The milling-spindle 2, driven by a belt pulley 5, is mounted eccentrically in an inner bush 3 which is itself mounted eccentrically in an outer bush 4 which is rotated to give the planetary movement of the cutter round the work by worm gearing 7 driven from a motor through belt pulleys, and bevel gearing. Another worm 15 driven from this train drives a wheel 16 rotatable on the outer bush and carrying a hollow ring 17 having a cam projection 18. The inner bush carries a ring 19 adjustably secured by screws 20, 21 which are loosened when the inner bush is to be rotated to adjust the diameter of the planetary movement. The ring carries a cam 22, and is constrained by springs 25, 26 so as to engage a projection 29 on the ring 19 with a projection 30 on the bush 4. The rotation of the inner bush to the work diameter is effected from a hand operated spindle 33 through worm gearing 36 and disengageable spur gears 32, 31. After completion of the cut, the cutter is withdrawn from the work by automatic relative rotation between the inner and outer bushes. Normally the inner bush is entrained by the springs to rotate with the outer bush but at a predetermined point, after the cutter has rotated a full 360‹ round the work the projection 22 on ring 19 overtakes and engage a projection 18 on the rotating ring 17 and thus prevents the bush 3 from rotating with the outer bush 4. This relative movement between the bushes serves to withdraw the cutter from the work. The relative forward movement of the outer bush after engagement of the parts 22, 18 tensions the springs 25, 26 and separates the abutments 29, 30. After an interval, owing to the eccentric rotation of rings 17, 19 the abutments 18, 22 come out of engagement and the relative positions of the bushes are restored by the springs which cause re-engagement of the abutments 29, 30.

Title: Improvements in and connected with the catalytic treatment of organic and inorganic substances
IPC: C10G1/06
Filed: 1931-04-18
Abstract: <PICT:0386982/III/1> In the destructive hydrogenation of coal mixed with oil or the catalytic treatment of liquids in admixture with gases or of mixtures of gases, the materials are passed together through a central inlet pipe 24 and pass outwards through radial channels in contact with a catalyst to a common outlet chamber.  The passages may be formed by superposed cones 36, with punchings 38 to keep them apart, resting upon a cone 34.  The cones 36 of metal or asbestos are coated with catalyst on one or both surfaces.  A catalyst consisting of powdered metal or oxides may be attached by coating the surfaces, while warm, with a silicon ester which may be dissolved in a solvent such as alcohol, dusting or sprinkling the catalyst on the tacky surface, and heating preferably in a reducing atmosphere.  The central inlet pipe may contain a mixing device consisting of deflectors 31 and wire gauze separators 32.  In hydrogenating coal, a pressure of less than 150 lbs. per sq. in. and a temperature of about 230 DEG  C. are used.  The materials may be passed in succession through a series of catalyzing chambers.

Abstract: 1384625 Tensioning SIEMAG SIEGENER MASCHINENBAU GmbH 13 March 1972 [17  March 1971] 11535/72 Heading B8R Apparatus for tensioning a strip comprises a plurality of guide bars, e.g. 11-13, symmetrically mounted on either side of the centre of each of a pair of spindles 2, 7 by the engagement of nuts, e.g. 16, 24, with screw threaded portions 15, 23, the pitches of the latter being proportional to their mean distance from the centre of the spindles and the crest diameter of the screw threaded portion 23 being smaller than the core diameter of the screw threaded portion 15. In the embodiment shown a vertical shaft 5 coupling the two spindles by bevel gears 4, 6, at least one of which is axially slidable on a splined portion 9 of the shaft 5. A fixed guide bar 10 is mounted at the centre of each spindle and the guide bars 11 and 13 are mounted on the nuts 16 and 24 respectively. The guide bars 12 are mounted on shafts 18 which are rotatably mounted on the nuts 16 and coupled to the spindles in a non-rotational but longitudinally slidable manner by keys 19 in keyways 20. The guide bars 13 mounted on the lower spindle carry edge guides 14. When the width of strip is to be changed, the spindle 2 is rotated by a chain 3, the rotation of the spindle 2 also causing the rotation of the spindle 7 via the bevel gears 4 and 6. The rotation of the spindles causes the guide bars 11 and the shafts 18 to move outwardly, as seen in the right hand half of the Fig. the shafts 18 also being rotated to cause the guide bars 12 to move outwardly. In this way the guide bars 12 are displaced by double the distance through which the bars 11 are displaced. The rotation of the spindles also causes the nuts 24 to move outwardly, the pitch of the screw threaded portions 23 being such as to displace the bars 13 and guides 14 three times the displacement of the bars 11. In another embodiment the shafts 18 are replaced by screw threaded portions on the spindles, the screw threaded portions overlapping with the screw threaded portions 15 to form a double helix.

A hook 10 maintains the cutters in the closed position against the action of a spring 7 and in this position, the wall 5<a> diverges from a line joining its outer end to the pivot 3 in the direction in which the cutting edge 6<a> moves in approaching the wall.

Title: System for transmitting coloured characters

Filed: 1974-03-15
Abstract: 1466422 Cathode-ray tube displays NIPPON ELECTRIC CO Ltd 15 March 1974 [15 March 1973] 11665/74 Heading H4T In a system for transmitting computer generated colour graphic characters a character representing video signal is transmitted over a first path and a colour-determining digital signal is transmitted over a second path. The transmitter includes a video encoder responsive to input data from a digital store to produce the video signal and a colour signal generator responsive to the input data to produce the colour-determining signal in the form of a synchronizing pulse timed with respect to the video signal and followed by a sequence of colour determining binary code pulses. Horizontal and vertical synchronizing signals are added to the video signal and at the receiver a decoder responsive to the colour-determining signal reproduces the sequence of code pulses as a parallel binary signal and this together with the video signal is supplied to a colour display unit. With this arrangement there is substantially no mutual phase shift between the respective (Red, Green and Blue) colour signals and any difference in the lengths of the transmission paths (cables) is compensated by an adjustable delay line which controls the instant at which the parallel binary colour signal (derived by the receiver decoder) is combined with the video signal to form the composite signal supplied to the display unit. The whole operation is described with respect to block and other circuit diagrams together with the waveforms operative at various points in the circuits.
