Title: Improvements relating to electrical duplexers
IPC: H01J17/04
Filed: 1957-02-13
Abstract: 843,634. Waveguide accessories. COMPAGNIE FRANCAISE THOMSONHOUSTON. Feb. 13, 1957 [Feb. 14, 1956], No. 4940/57. Class 40(8). [Also in Group XL(a)] One or more discharge tubes are positioned in a coupling aperture in the common narrow wall 4 of two contiguous waveguides. The tubes are arranged to fire when the coupled energy exceeds a certain level. The discharge tubes 6, Fig. 1, (only two shown), have metallized ends 8 which make contact with metallic collars 10 through conductive rings 9. The tubes are secured by threaded bushes 11. The whole of the aperture 5 may be occupied by a tube in the form of a parallelopiped 62, Fig. 5, whose upper and lower surfaces are metallized and electrically connected to the walls of the guides. Better coupling between the two guides may be obtained by using two spaced apertures each provided with discharge tubes. Where the coupling is used as a duplexer in a TR system, one of the waveguides is connected between a transmitter and an antenna and the other between a receiver and a dummy load. In order to reduce the level of energy transmitted by the duplexer, two duplexers may be arranged in parallel, energy from the transmitter and from the antenna being equally divided between the two duplexers by means of known 3 db. couplers (Figs. 4a, 4b, not shown).

Title: Improvements in or relating to cellular material
Inventor: PARKER ROBERT SYDNEY RICHARD
IPC: C08J9/00
Filed: 1963-02-07
Abstract: Rigid or semi-rigid cellular material may be produced by a process which comprises mixing a polymer or copolymer of vinyl chloride, a polyisocyanate, a blowing agent and an adduct of maleic anhydride and a diene, heating the mixture in a mould under pressure to form a partially expanded material, cooling the mould under pressure then removing the partially expanded material and completing the expansion by heating the material in the presence of water or water vapour. Suitable polyisocyanates are the p,p1,p11-triisocyanate of triphenyl methane, p,p1-diphenyl methane diisocyanate, toluene 2,4-diisocyanate and toluene 2,6-diisocyanate.  The preferred blowing agents are azo-compounds, e.g. azo-di-isobutyric di-nitrile, azo-di-isobutyric amide oxime and azodicarbonamide; sulphonyl hydrazides, e.g. p,p1-oxy bis-(benzene sulphonyl hydrazide) and benzene sulphonyl hydrazine; hydrazones, e.g. benzil hydrazones; organic nitrites, e.g. tertiary butylenine nitrite; nitroso compounds, e.g. N : N1 - dinitrosoethyleneurea, N : N1 - dinitroso N : N1 - dimethylenephthalamide and N : N1 - dinitroso - pentamethylenetetramine; ureas and salts of ureas, e.g. urea oxalate and substituted ureas and their salts, e.g. aminoguanidine bicarbonate and nitrourea.  Fluorocarbons may also be used and blowing agents. In forming the adduct the suitable dienes are cyclopentadiene, transpiperylene, furan, isoprene and especially butadiene.  Other unsaturated anhydrides may be added to the mixture in addition to the maleic anhydride adduct, e.g. itaconic anhydride, acrylic anhydride and citraconic anhydride.  A modified form of the invention comprises first forming a grafted polymer of polyvinyl chloride and maleic anhydride to be used in place of the polymer or copolymer of vinyl chloride.  Additives such as stabilizers, plasticizers, fillers and pigments may also be incorporated in the mixture.

Title: Automatic control of television receiving systems
IPC: H04N5/52
Filed: 1939-02-16
Abstract: 525,284. Automatic control of television receiving apparatus. HAZELTINE CORPORATION. Feb. 16, 1939, No. 5214. Convention date, March 15, 1938. [Class 40 (v)] In a television system in which the intensity of general illumination is transmitted by the average intensity of the carrier, the signal during the frame retrace period, which is modulated by synchronizing pulses only, is used to provide a controlling potential which is responsive to the intermediate amplitude-level of the modulation envelope of the signals, but independent of its " timing " characteristics. The derived potential may be used for automatic volume selectivity, or tuning control, but as described is applied to volume control only. The signal output from detector 15, Fig. 1, is applied to valve 20, and if the input signal is as shown in Fig. 2 the anode current of valve 20 is as indicated in Fig. 4. The time period of condenser 26 and resistance 25 is long compared with the line blanking periods, but short compared with the frame blanking periods, so that the voltage developed across condenser 26 is of the form shown in Fig. 5. This voltage is subtracted from the anode voltage supplied at B so that a voltage as indicated in Fig. 6 is obtained by peak rectifying anode 21 reversed by valve 22 and applied through smoothing filters 30, 31 as a control voltage to the radio frequency amplifier 12, the oscillation modulator 13, and the intermediate frequency amplifier 14. Battery 33 is provided to compensate for the +B voltage. The control voltage is fairly steady and as it is derived from the unmodulated parts of the carrier, it is independent of light modulation components. The diagrams A in Figs 2, 5 and 6 indicate a signal of normal strength and those at A<SP>1</SP> a faded signal and it will be seen that the control voltage P, P<SP>1</SP> varies with fading.

Title: Improvements in sheet-folding machines
IPC: B65H45/14
Filed: 1926-02-25
Abstract: 248,383. Spiess, G. March 2, 1925, [Convention date]. Folding paper.-In paper-folding machines employing buckling-plates 1 and co-operating folding-rollers, the stop-bar in each buckling-plate is mounted so as to be capable either of parallel adjustment or of separate adjustment for each end. The stop shown in Fig. 1 is in the form of aT-bar 4 having near each end an upwardlyextending arm 5 secured by nuts 12 to a threaded spindle 11 carried by a bracket 7. The bracket 7 slides on a bar 6 and has a spring-pressed pin 9 which engages notches in the bar 6. To adjust the stop 4, the brackets 7 at either end are moved to obtain an approximate adjustment, and the nuts 12 are employed for a fine adjustment. The sheet is guided in the plate 1 by wires 3 passing through holes in the bar 4. In the form shown in Figs. 3 and 5, the stop-bar 13 has, near each end, a downwardly-depending nut 14 through which passes a screwed spindle 15. The end of the spindle 15 removed from the folding-rollers passes through a sleeve 23 externally threaded to engage a nut 21 in the plate 1. Hand-wheels 24, 17 are secured to the sleeve 23 and spindle 15 respectively, so that the stop-bar 13 can be adjusted by turning either of these wheels. The wheel 17, however, is used for simultaneously adjusting both ends of the bar 13 by means of a chain passing over sprocket wheels 18 secured to the spindles 15, separate adjustment being obtained by means of the wheel 24. A spring 25 engages teeth on the periphery 26 of the sleeve 23 to retain it in adjusted position. The nuts 14 may be mounted so as to swivel on the stopbar 13.
