Patent GB-874420-A (GB)
Title: Oscillator with amplitude stabilization and starting phase correction
IPC: H03B5/34
Filed: 1960-05-31
Abstract: 874,420. Valve oscillating circuits. COLLINS RADIO CO. May 31, 1960 [July 2, 1959], No. 19278/60. Class 40(6) In a crystal oscillator the crystal 2 forms, with a series-connected harmonic-suppressing choke 3, the grid circuit of the oscillator valve 1. The anode circuit comprises a choke 8 shunted for A.C. by a tuned circuit which includes a variable inductance 12. In such an arrangement, if the anode tuned circuit is adjusted for maximum power output, the circuit will not recommence oscillation unless the anode tuned circuit is readjusted to a different value. According to the invention the change in adjustment is performed automatically by connecting across the inductance 12 a condenser 14 in series with a diode 16, so that the effective capacity of the tuned circuit depends upon the amplitude of oscillation. The condenser 14 forms the coupling to a subsequent stage 15, and the diode 16 also maintains the amplitude of the oscillations applied to this valve constant.

Title: Improvements in or relating to labelling machines
Inventor: FAIREST MORGAN
IPC: A63C9/22
Filed: 1953-07-11
Abstract: 744,329. Labelling machines. FAIREST; Ltd., M. July 5, 1954 [July 11, 1953], No. 19294/53. Class 73 In a "top-strapping" labelling machine as described in Specification 744,318 in which a detector 89 Fig. 7 in the feed line of the bottles 5, in the absence of a bottle, prevents the upward movement of the label stack 30 and thus contact with the suction head 16 for withdrawal of a label, the detector 89 also controls the rocking movement of the gumming roller 72 towards contact with a label on the suction head 16. This control is effected by means of a rubber diaphragm 99, one side of which is connected to the suction line of the head 16, a spindle 108 secured to the diaphragm actuating a solenoid 136 to rock the gumming roller 72 into label contacting position under the influence of the suction applied to the diaphragm 99 when a label has been withdrawn by the head 16. With an uninterrupted bottle feed, a label withdrawn from the stack 30 by the suction head 16 closes the suction apertures therein and a sufficient degree of suction is reached in the suction line to actuate the diaphragm whereupon the gumming roller 72 is rocked into label contacting position; on interruption of the bottle feed, the operation of the detector 89 prevents the suction head 16 from withdrawing a label from the stack, the suction apertures in the head remain uncovered and the suction is not sufficient to actuate the diaphragm. Consequently the gumming roller 72 is not rocked and gum is not applied to the uncovered face of the head 16. The diaphragm is loaded by a spring 118 which can be adjusted by a nut 116 so that the suction in the space 105 required to depress the diaphragm is greater than the suction available when no label is held by the head 16. On actuation of the diaphragm the upper end 112 of the spindle 108 deflects the spring arm 113 of the micro switch 114 which closes a circuit 135 in which the solenoid 136 is connected. The solenoid 136 pulls a link 137 connecting it to a lever projection 138 depending from a lever bracket 74 and rocks the bracket to swing the roller 72 from the inoperative position up to the head 16. A spring 139 acting on the link 137 tends to rock the' roller 72 into the inoperative position. Absence of a bottle 5 causes the detector 89 to close a circuit 90 in which a solenoid 91 is connected. This solenoid pulls on a slide 94 Fig. 6. which in turn prevents the outward radial movement of a cam 59 which controls the vertical movements of the label stack 30. The cam 59 is thus held out of the path of a follower roller 60 rigid with the stack 30, the stack is not lifted and no label extracted.

[Also in Group XII] In an open circuit gas turbine plant using solid water-containing fuel, the fuel is passed through a drier arranged before the combustion chamber and the separated water content as well as the products generated in the combustion chamber are passed through the turbine. The fuel used may contain at least its own weight of water, and may consist of undried peat, bagasse, sewage sludge, coal slurry, sulphite pulp-mill waste or town refuse. Fig. 1 showns a plant using peat as a fuel on the site where the peat is gained. Peat gained at 18 is moved by a conveyer 24 in contra-flow to the turbine exhaust and passes by a pipe 19 to a press 20 where the free water is removed. The peat passes through a pre-drying chamber 21, with the turbine exhaust, is separated at 22 and is delivered by a pump 23 to a drying chamber 7. It is mixed with preheated air from the compressor 1 and heatexchanger 6, is pulverized by a hammer mill 8 and delivered tangentially to a combustion chamber 10. Combustion takes place in a whirling stream and the combustion products emerge from an axial outlet 13. They pass through an ash separator 14 to a useful power turbine 4 and a compressor turbine 3. Combustion products are bled off by a pipe 16 and led through the drier 7. Coarser peat particles are separated before the combustion chamber and returned by a pipe 12 to the drier. Part of the gas and vapour content of the materials in passage 9 may be separated and conveyed around the combustion chamber to the outlet 13. The turbine plant is started with an auxiliary fuel such as kerosene. The turbine plant coupled to an alternator may be mounted on a caterpillar tractor, used at the site of a peat deposit and linked by cable to a transmission line sub-station.

Title: Fibrous webs and method and apparatus for making same
IPC: D21F11/00
Filed: 1965-05-10
Abstract: A wet-laid non-woven fabric web having the hand and drape of a woven fabric-for use as a filter, table napkin, towelling bandage, bookbinding &c. is formed in a paper-making machine by depositing an aqueous dispersion of fibres on a screen assembly which comprises a base screen member-for example of Fourdrinier wire - having superimposed thereon a moulding screen member of coarser mesh so that the web has a greater fibre concentration between the elements of the moulding screen member than thereon. The coarser screen member may be a woven screen having less than a 1/10th and preferably less than 1/50th of the number of apertures in the fine mesh screen, and may have solid discs secured to the member to block off selected areas of the screen so that the formed web has circular portions of low fibre concentration (Fig. 14, not shown).  The coarser screen member may also be corrugated or have protrusions to form a corrugated or creped web.  The crepe may be of over 100% and be in the machine and/or cross-machine directions.  A Four-drinier, rotoformer, or cylinder machine may be used.  The fibres in the slurry should be well dispersed by having a concentration of substantially less than 5% or by using a dispersing agent.  The strength of the web may be increased by treatment with latex, polyvinyl chloride or cationic agents, or by a post-formation treatment-such as spot welding. Fibres of hemp, casoa jute, kraft, rayon, nylon, polyester or vinyl copolymers may be used.

Abstract: 691,509. Electrolytic etching; electrolytic condensers. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 21, 1951 [Aug. 29, 1950], No. 19697/51. Classes 37 and 41. Tantalum is etched in order to provide an increased effective area when used as a capacitor electrode by treatment as anode in an electrolyte comprising ;at least 6.5 per cent by weight of methanol, a trace of water and a methanolsoluble inorganic halide. Methanol may constitute the sole organic solvent tor may be admixed with other organic solvents ;such as ethylene glycol, ethyl alcohol, isopropyl alcohol, nitrobenzene, glycerine, diethylene glycol monoethyl ether, or formamide. The inorganic halide is preferably a fluoride, e.g. ammonium fluoride or bifluoride, or fluoride of lead, calcium, sodium, copper or beryllium; it should be present in amount sufficient to permit passage of a current. Other ;suitable halides are nickel chloride, lithium chloride, calcium chloride, potassium bromide and sodium iodide. The concentration of ammonium fluoride may be 1.3-4.1 per cent or of ammonium bifluoride 0.62-6.1 per cent; mixtures of these salts may be used. The water content of the solution may be 3.000- 50,000 parts .by weight per million. The ratio of the effective area of the surface produced by the etching to the projected area may be 1.5-6.5 or more. A ratio of 6.65 was obtained by using a solution containing 58 per cent methanol, 39.8 per cent ethylene glycol and 2.2 per cent ammonium bifluoride with about 4200 parts per million of water at 20-25‹ C. The temperature of the solution may be 20- 65‹C.; the lower temperatures in this range are employed when a low voltage is to be employed in the subsequent treatment to develop a dielectric film on the surface. The capacitator may comprise tantalum strips 10, 11 etched in accordance with.the invention and separated by strips 12, 13, 14, 15 of paper or other porous insulating material, all wound into a compact roll for impregnation with a suitable-electrolyte before or after insertion in a container. Terminal straps 17, 18 are fixed to the respective strips and extend through insulating plugs at either end of the container.

Abstract: 1,001,818. Measuring radiation; electrolytic, meters. QUARZLAMPEN G.m.b.H. May 23, 1962 [June 3, 1961], No. 19832/62. Headings G1A and G1Q. A radiation measuring apparatus comprises a photo-electric cell which receives the radiation to be measured and which is electrically connected through a variable resistor to an electrolytic meter at which a measurement proportional to the integral of the incident radiation with respect to time can be read off. In the embodiment shown radiation, such as light, from a source 10 passes through a filter 14 and is received by a silicon photo-emissive cell 16 which is connected through a variable resistor 18 to an electrolytic meter 24 of the mercury type which gives an indication of the total amount of radiation received by the cell during a given time, the scale 38 of the meter 24 being calibrated in either watt-seconds per unit of area or lux hours the range being determined by the setting of the resistor 18. The electrolytic meter 24 has a bulb 26 in which a semipermeable frit plate 28 is arranged at an angle to the horizontal with one of the electrodes 20 of the meter above it and one 22 below it and immersed in the electrolyte 36. An amount of mercury 32 is contained above the frit plate 28 and in electrical contact with the electrode 20. As a result of current produced by the photo-electric cell 16 mercury passes through the frit plate into the vertical measuring tube 34. The meter may be re-set to zero by inverting it and allowing mercury which has collected in the tube 34 to flow back to above the frit plate through an aperture 30. Additional photoelectric cells may be connected in series with the cell 16 to increase the voltage output thereof.
