Title: Coated sheet material
IPC: B41M5/124
Filed: 1974-07-04
Abstract: 1476787 Coated paper; generating foam WIGGINS TEAPE Ltd 20 June 1975 [4 July 1974] 29729/74 Headings B1C and B2E [Also in Division D2]  A microcapsule-coated paper for use in pressure sensitive copying systems is made by first foaming a coating composition containing the microcapsules and a particulate stilt material, applying the foamed composition to the paper, metering the composition on the web to a desired coatweight by means of a metering member in contact with the composition on the web, and drying the composition to leave an unfoamed coating on the web. The metering member may be a rigid or flexible blade, a Meyer bar, or roll. The stilt materials may be cellulose fibre floc, granular starch particles, granular synthetic polymers, hollow or liquid-containing capsules of a size greater than the microcapsules, or particulate mineral materials e.g. talc, or pigments. A foaming agent e.g. polyvinyl alcohol, gelatin, casein, soyabean extract, saponin, surfactants may be used. The binder may itself produce an adequate foam. Examples of such binders are the proteins specified above and polyvinyl alcohol. Foaming apparatus. Coating composition in tanks 16, 17 is pumped to a vortex cleaner 19 into which air is introduced via line 20. The mixture is then passed to a high shear mixer 23 to produce a foamed composition. The bubble size of the foam is made smaller by passage of the foamed composition through nozzles 24 and tubes 25, and the resulting foamed composition is passed to a fountain applicator 14 for application to a web 2. In an alternative arrangement (Fig. 3 not shown) a coating composition is foamed with air in a closed in-line mixer, e.g. a closed tank containing a rotatable paddle, and the resulting composition is pumped through a foam generator to a fountain applicator.

Title: Improvements in preparatory treatment of pulverised fuel for engines and furnaces
IPC: F23K1/00
Filed: 1930-10-04
Abstract: 370,461. Fuel ; preparing peat. PAWLIKOWSKI, R., 16, Cottbuser Strasse, G÷rlitz, Germany. Oct. 4, 1930, No. 29740. [Class 50.] Pulverized fuel produced from coal, lignite, peat, and coke after coarse grinding is subjected to two successive treatments with acid and subsequent washing, to remove alkaline salts, in order that the oxide earths in the ash may become finely disintegrated in the furnace or engine. The treatment chamber is lined with the particular substance under treatment, for example in the case of coal by briquettes of coal combined with asphalt, or lime is added during treatment to protect the iron walls of the chamber. The coarsely ground coal is delivered through a pipe r to the first chamber b and is treated with diluted mineral acid admitted by the pipe a. The mixture is delivered from the end of the chamber b by a scraper (onveyer c to a slope e leading to a second chamber f. The used acid from the chamber b passes into a mixing vat g to which lime is added, and the slightly acid liquid flows from the vat to the chamber f for the second treatment. The vessel f has a double bottom door for the discharge of dross, and the fuel mixture is delivered by a second conveyer to a washing slope and afterwards to a drying chamber. The treatment and drying chambers may be heated by engine exhaust gases and the warm engine jacket water may be used for the washing.

Title: Improved means and method of applying a surface layer of grease or the like to an electric cable
IPC: H02G1/08
Filed: 1930-10-06
Abstract: 364,572. Coating electric ables. STANDARD TELEPHONES & CABLES, Ltd. and BISHOP, H. S., Columbia House, Aldwych, London. Oct. 6, 1930, No. 29837. [Class 140.] In a device for applying a layer of grease to the exterior of an electric cable as it is drawn into a duct, the grease is applied by mechanically controllable pressure directed upon an extrusion head disposed about the cable where the latter enters the duct. The extrusion head may be flexibly coupled to a guide member which is adapted to fit the mouth of the duct. In the form shown in Fig. 1, grease is placed in the upper part of a container 1 above a movable diaphragm 2; the latter is forced upwards by oil under pressure supplied by means of a hand pump 8 from a reservoir 5. A byepass pipe and cock 112 permits the pressure to be released and the oil to flow back into the reservoir 5 when the container 1 is to be recharged with grease. The grease forced from the container 1 passes through a pipe 11 to the extrusion head 14 which comprises an annular chamber 15 from which a number of ducts 16 lead to the interior through which the cable 17 passes. The head carries a flexible tubular member 18 of leather or the like which is held against the cable 17 by a spring band 19, the grease being thus evenly applied. The head is attached by two pivoted links 21 to a flared tube 22, Fig. 2, which fits inside the mouth of the duct. A modified form of extrusion head is shown in Fig. 4. A narrow slot 29, which may be adjustable, takes the place of the ducts of the previously described form. The pressure of the flexible member 18 on the cable is provided by means of a pneumatic pressure tube 19 which is inflated through a valve 30. A band 31 of tape or the like prevents expansion of the tube 19 in an outward direction. Universal movement between the extrusion head and the flared member 22 is provided by means of an annular member 22a which is connected by pivoted links 21, 21a to the head and to the member 22 respectively. The device may be applied to the lubrication of aerial cables by supporting it upon a tripod 33, Fig. 6, having a boss 34 adapted to fit inside the members 22, 22a. The boss carries lugs 36 which engage the links 21.

Abstract: 1,109,224. Making pile fabrics. BERGEDORFER EISENWERK G.m.b.H. ASTRAWERKE, S. S. C. FLEISCHER, C. C. THOMSEN, and P. DURRSCHMIDT. 14 July, 1965 [16 July, 1964], No. 29950/65. Headings DIE and D1K. Pile tufts n are fed to a carpet making machine by assembling them in carriers 89 mounted on endless conveyor chains. The tufts are located by insulated spacers 90 and metal combs 99. Yarns are supplied by colour selector bars similar to those employed in gripper Axminster looms. A row of grippers 16 first moves horizontally from c to d to draw out sufficient yarn for a row of tufts, which are then cut by an endless band knife; the grippers then move along the path d to e to deposit the tufts between the spacers 90 of a carrier. The tufts are pushed home by plungers which, if a tuft is missing, touch the combs 99 to complete a stop motion circuit. The length of tuft can be changed by modifying the path of the grippers 16; if the straight movement cd is extended to d', the final movement is extended by ee', which is half dd', so that tufts with equal legs are always formed.

Title: Improvements in or relating to demodulating circuit arrangements
Inventor: PARKER-SMITH NORMAN NEVILLE
IPC: H04N5/16
Filed: 1948-11-22
Abstract: 663,874. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 28, 1949 [Nov. 22, 1948], No. 30330/48. Class 40 (iii). [Also in Group XL (c)] In a circuit for demodulating a pulse or sine wave signal modulated by, for example, a D.C. signal, of the type in which the modulated signal is fed to a phase-splitter, the outputs of which are applied to D.C. restorers supplying outputs of the same polarity, one output or each output from the phase splitter is used to control the time constant of the D.C. restorer fed by the other. By this means the circuit may be made responsive to rapid changes in the signal amplitude without reducing the time constant of the D.C. restorer between successive pulses or cycles. In one known circuit the outputs from a phase-splitting valve 3 are fed to similarly arranged D.C. restorers comprising diode or other rectifiers 22 and 23 and the two resulting outputs are combined in a common resistor 17 of two corresponding amplifier valves. In a second known circuit, Fig. 2 (not shown), a transformer phase-splitter feeds two leaky grid restorers, the outputs from the anodes of which are combined in a common resistor. In some cases the D.C. modulation varies too rapidly for the time constants of the restoring circuits to follow. This applies, for example, in television systems when the input signal is in the form of short pulses derived through gating circuits during the black level period at the commencement of the scanning lines since the black level may vary from time to time but is required to be held constant during the rest of the time period. In Fig. 3 the phase-splitter valve 3 feeds parallel output valves 11, 12 as in Fig. 1 through similarly-arranged D.C. restorers comprising diodes 30 and 23. The charging circuit for the capacitor 9 of the first D.C. restorer includes however a further diode 28 in series with a small resistor 29. During the main part of the line period a valve 32 connected in series with resistor 29 is conductive and diode 28 is therefore blocked by the voltage developed across the resistor. Part of the input pulse, however, is fed from the cathode of the phase-splitter through capacitor 40 and a limiter valve 37 to cut-off valve 32 and render the diode conductive for the duration of the pulse so that the charge on capacitor 9 can rapidly readjust itself. The time constant of the other rectifier may be similarly controlled by the output, from the anode of the phase-splitter. When a sinusoidal input is applied to terminals 1 and 7 it is necessary to tune the output circuit of the limiter. According to the Provisional Specification resistor 31 may be connected to the H.T. supply instead of to earth. The output voltage from terminals 18 and 19 may be used to control the black level in a television transmitter or to provide an A.G.C. potential in a television receiver.
