Abstract: 585,462. Valve amplifying circuits; electric resonators. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. April 19, 1943, No. 6276. [Classes 40 (iii) and 40 (v)] A transmission line, which may be used as a resonator to provide an intervalve coupling, comprises a metal plate divided in three separate co-planar portions by parallel gaps, the edges of the outer plates may form flanges normal to the principal surfaces of the plates to obtain a lower characteristic impedance, Figs. 2, 3, 4 whilst the central conductor may be cylindrical or flat. A resonator may consist of a metal plate with a U-shaped slot cut therein, alternatively a grooved plate with the face divided by two parallel grooves may be used, the depth of the grooves being substantially one-quarter wavelength. Figs. 10, 12, 13 show the construction of amplifiers in which the input intervalve and output couplings are constituted by plates 14, 14<1> having U-shaped slots forming tongues 14a therein, Fig. 13. The tuning may be adjusted by a condenser consisting of the plate 15 formed from the bent over free end'of the tongue 14a and an adjustable plate 16. The coupling,may be adjusted by varying the spacing between the plates 14, 14<1> or the use of an adjustable plate 26, Fig. 10, -which provides magnetic screening. A valve of the grounded grid type such as described in Specifications 585,448, 585,449, 585,450 and 585,452 may be mounted in the metal partition 9, the input being coupled to the cathode 10 on the potential antinode in the line for short waves. The first antinode may be within the valve in which case a loading coil 18 is provided so that the second antinode of potential coincides with the point of connection to the line. Valve electrodes are connected to H.T. and L.T. through springs 28, 29, 30, Fig. 12, and rails 21, Fig. 13, which make contact when the box 13 is placed on the tray 25. Mica strips between the springs and boxes may form the necessary blocking condensers which together with the inductance of the conductor form low pass filters. The provision of the reactance 18, together with means for adjusting tappings to the lines 14, 14<1> are used to equalise the " Q " of the grid cathode circuit of one stage to the " Q " of the circuit to which it is coupled to avoid the mis-matching consequent on the high ratio of output to input resistance due to the use of inverted valves.

Patent GB-676910-A (GB)
Title: Purification of cellulosic materials
IPC: D21C9/08
Filed: 1950-03-15
Abstract: Cellulosic material, especially wood pulp, is chlorinated and subsequently heated with a 0.1-5 per cent aqueous solution of caustic alkali at a temperature of at least 160 DEG  C.  If desired the chlorination may be preceded by a preliminary treatment with about 0.25-1.25 per cent caustic soda at about 120-135 DEG  C., and the material may also be bleached at some stage or stages following chlorination.  The chlorination is preferably carried out by treating the pulp as a 2.0-3.5 per cent suspension in water for 30-60 minutes at 10-30 DEG  C.  The amount of chlorine used is about 50-70 per cent of the chlorine demand of the pump at this stage as determined by the permanganate number.  The chlorinated pulp is washed with very dilute caustic soda (about 0.02-0.20 per cent) until alkaline.  The main alkali treatment is carried out on a 1-12 per cent suspension of the chlorinated pulp at a temperature of at least 160 DEG  C. and preferably between 160 DEG  and 185 DEG  C. for 15 to 30 minutes. This treatment may be carried out in stages, using fresh solution for each stage, and in one or more of such stages the temperature may be below 160 DEG  C. provided that this temperature is reached or exceeded in one stage and held for 15-30 minutes or more.  Bleaching treatment, if required, may be carried out with alkaline hypochlorite at pH 10-11 containing 0.25 to 1.0 per cent available chlorine at 25-40 DEG  C. for 2-4 hours, the pulp being bleached as a 3.5 to 14.0 per cent suspension.  After bleaching the pulp may be washed until substantially neutral.  An apparatus is described comprising a vertical treatment column or digester through which the pulp suspension is circulated downwardly by a pump and attached conduits provided with valves for the admission of water and treatment chemicals.  The column is also provided with a steam pipe for heating the suspension.  In an example an 8 per cent suspension of sulphite wood pulp in 0.4 per cent aqueous caustic soda is pretreated in the digester for 15 minutes at 122 DEG  C.  The pulp is drained and water added to make a 2 per cent suspension to which 1.5 parts by weight of chlorine is added per 100 parts by weight of pulp.  Chlorination takes place for 50 minutes at 25 DEG  C., and the pulp is then drained and washed alkaline with 0.2 per cent caustic soda.  The pulp is then formed into a 6.25 per cent suspension with 1.3 per cent caustic soda and heated in a digester to 170 DEG  C. and held at this temperature for 15 minutes.  The purified pulp is washed with hot water, bleached with aqueous hypochlorite (0.3 per cent available chlorine on pulp weight) at 35 DEG  C. for two hours, washed and finally dried.

Abstract: 1,210,624. Liquefied gas storage containers; cryostats. MAX-PLANCK-GES ZUR FORDERUNG DER WISSENSCHAFTEN E.V. 6 Feb., 1969 [13 Feb., 1968], No. 6593/69. Headings F4H and F4P. A radiation shield surrounding a vessel containing a liquefied gas is cooled by a heat exchanger which is fed with exhaust gas from the vessel and which has an internal crosssection larger than that of the pipe leading the gas to it. The vessel may be a cryostat or a reservoir for supplying a cryostat. As illustrated, the radiation shield contacts a heat exchanger whose internal wall has a helical element 3 which, together with a plug 15 defines a helical flow path for the exhaust gas flowing in a pipe 4. If it is necessary to introduce inserts into the vessel through the pipe 4 the plug 15 may be omitted. In this case, a pipe for the inserts may be enclosed within the pipe 4 and be contacted by the helical element 3, the exhaust gas then flowing in the annular space between the two pipes. In an alternative form of heat exchanger, Fig. 4 (not shown), the helical element is omitted and a sintered metal plug fills the transverse cross-section of the heat exchanger.

Title: Improvements in selection of sounds and apparatus therefor
IPC: G01S1/72
Filed: 1919-03-17
Abstract: 144,799. Burgess, J. A., and Hutchings, G. B. March 17, 1919. Detecting subaqueous sounds; receiving audible signals.-A sound-selective arrangement, particularly for detecting subaqueous noises, comprises means whereby undesired sound frequencies are eliminated by interference. Resonators for strengthening the desired frequency may be used in conjunction with the interference apparatus. As described, the received sounds affect a submerged resonator 17 having a sound-insulating casing 18. A microphone 16 transmits the impulses to a diaphragm soundproducer 14 of ordinary telephonic type. A megaphone 13 directs the sound produced to the first of a series of resonators 11, preferably three in number and with their axes at right-angles as shown. The resonators may, however, be mounted on supports allowing any desired adjustment of their relative positions. The sound then passes through a series of interference devices, each of which suppresses a particular frequency. Each device comprises a looped tube offering two paths for the sound between the entrance and exit. The paths are adjusted to differ in length by an odd multiple of half a wave-length for the frequency to be suppressed. Thus sound passing, for example, from the entrance tube 19 to the exit tube 25 traverses the two paths 20, 29, the latter of which comprises a U-form telescopic member so that the length of path can be adjusted by a rod 34. Any required number of similar interference devices, adjusted for the suppression of different frequencies, may be used in series. Five are shown. The purified sound passes to a listening head-piece 40. If desired, the sound may effect a second microphone 41, the current impulses, after amplification, by any suitable device 42, being reconverted into sound impulses, which are passed through a second series of interference devices, represented at A, to a head-piece 43. Fig. 3 shows a modified form of interference device comprising a tube with a closed end, and either straight, 44, or curved, 45, co-operating with a second tube having a telescopically adjustable end closure 46 or 47. Fig. 6 shows a. modified form of resonator comprising a cylindrical portion 48 fitted with an adjustable portion 49 having a passage-way 50 leading to a tube 52 for the passage of the amplified sound.

Title: Improvements in electric selective signalling and control systems
IPC: H04M3/40
Filed: 1927-03-10
Abstract: 291,874. General Electric Co., Ltd., and Clark, H. C. Hannam-. March 10, 1927. Party-line direct-call systems.-In a system in which an amplifier is provided at each station, selection is effected by means of impulses of alternating current of audible frequency which control step-by-step selector switches. The figure shows an intermediate station on the line with a two-way amplifier R. In the case of the end stations, a simplified form of amplifier may be employed. When a subscriber removes his receiver 14, relays 17, 19 energize, and when the dial 20 is moved off-normal, relay 23 energizes and connects the A.C. leads 26, 27 to the line by way of the dial 20 and the amplifier R. At each other station, the dialled impulses are received over leads 33, 34 by a rectifier 37 and relay 38 (or merely an A.C. relay) and control the selector magnet 40. Relay 41 remains energized during impulsing, and relay 59 is energized as long as the selector is off-normal. When relay 41 falls back, relay 50 pulls up and opens the impulsing circuit of that station. The connections of each selector are distinctive of the station, and at the called station, calling lamp 45 lights, and relays 17, 19 complete the talking circuit when the called subscriber removes his receiver. At the remaining stations, however, engaged lamp 47 lights in series with relay 46 which prevents the energization of relay 17. When the called party hangs up, relays 17, 19 relapse in turn, and relay 52 pulls up and disconnects relay 59, so that the selector of the called station restores. When the calling party hangs up, relays 17, 19 relapse and relay 23 energizes momentarily, and sends an impulse over the line to serve as a clearing signal. This energizes relay 52 at the remaining stations and causes the selectors to restore. A conference call between more than two stations may be held by stepping the selectors to the last position, when all the calling lamps 45 are connected up. A key 64 may be provided for restoring the selector at a control station for interrupting an existing call.
