Filed: 1967-07-26
Abstract: 1,195,233. Non woven fabric, paper. JOHNSON & JOHNSON. 26 July, 1967 [26 July, 1966], No. 34300/67. Headings D1R and D2B. An expanded nonwoven fabric is made by impregnating a web with a binder and a foamaible liquid, vaporising the liquid within at least a portion of a fibrous web to puff at least a portion of the web then stabilising (or bonding) at least a portion of the puffed portion by setting the binder. The web can be impregnated with a solution or emulsion of the binder, e.g. an acrylic compound, if desired, only at discrete portions of the web. The binder may be present in the web before impregnation with the foamable liquid. The latter may be a solvent for the binder during heating. The foamable liquid can be water-containing fatty acid or sulphonated alkyl ester foaming agents. The binder can also be present in the foamable liquid impregnant or as thermoplastic fibres or powder, e.g. plasticised cellulose acetate. Preferably the web is heated dielectrically using electrolytes, e.g. NH 4 CL in the foamable liquid if necessary so that the web is heated only whilst the liquid is present. The degree of puffing varies with the thickness of the web, the conductance of the liquid, the amount and foamability of the liquid and the energy level of the dielectric heater. After puffing; the binder may be concentrated near the faces of the web, the web may contain randomly arranged fibre strata and fibre chambers, and the fibre density adjacent at least one surface may be greater than in the centre of the web. The initial web can be air-laid or wet-laid. A wet-laid web may be pressed before puffing. The web may contain fibres of cotton, linen, hemp, silk, wool, wood pulp, rayon, acetate, polyester, acrylic or modacrylic compounds. The fibres preferably have a length of less than 0.5 inch.

Title: An improved machine for grading tea and other substances
IPC: A23F3/00
Filed: 1929-11-14
Abstract: 339,758. Firman, W. G. Nov. 14, 1929. Pneumatic separating.-In apparatus for grading tea and other materials by transverse air currents, the material is fed by the device described in Specification 8002/10, [Class 59, Grinding, crushing, &c.], modified by the provision of means which automatically stop the feed when the pressure in the main air chamber falls below the required amount. The feed hopper comprises two converging bottom plates 1, Fig. 6, carried by shafts 2 with cranks 3 connected to a pivot 5 by links 4. The pivot 5 is slidable in a lever 9 actuated by a crank and connecting rod to rock the plates 1, and is held in contact with an adjusting screw 8 by a spring 14 which is supported by a bar 15 carried by links 16 from a pivoted bar 17 loaded at one end by its own weight or a spring 26 and normally maintained in its upper position by a latch 19. A valve 24 at the open upper end of the main air-chest is carried by a spindle 22 cut away at 23 so that when the air pressure falts, the shaft turns and allows a rod 21 to fall and release the latch 19, whereupon the bar 17 falls and moves the pivot 5 in line with the pivot of the rocking lever 9 to close the plates 1. The separating apparatus, Fig. 1, comprises the main air-chest 25 from which a number of air jets pass into a corresponding series of collecting compartments carrying with them the graded products. The first compartment 40 is provided with a wire screen 38 on which the material is fed by the hopper. A jet of air 39 carries the dust and fluff through thescreen, the dust being deposited on the floor of the compartmeut and the fluff collected in a trap consisting of a casing 41 with inverted cones 42 and open-ended truncated cones 43. Air jets 44 level with the floor carry the deposited dust to discharge. The material then falls in front of a jet 45 which blows the fine particles into a compartment 46 from which they are delivered by inclined boards to discharge shoots 48. The remaining material falls down the shoot 50 and is carried, according to grade, by an air jet 51 into a chamber divided into compartments 52, 53, 54. The air jets are formed by slots 56, Fig. 5, in the wall of the air-chest and are adjustable in size by boards 57 having inclined slots 58 engaged by pins on a longitudinally movable rod 59. The air jets 44 are formed in casings 64 external to the apparatus and connected to the air chest by flap valves.

Title: Improvements in or relating to gas-turbine or jet-engines
IPC: F02C7/26
Filed: 1945-12-27
Abstract: 625,810. Gas turbine and jet propulsion plant. BALLANTYNE, D. H. Dec. 27,1945, No. 34991. [Class 110(iii)] In starting a gas turbine or jet engine with an exhaust or jet pipe of considerable length, resonance in the pipe is prevented by opening a valve controlling an additional gas exit and closing it when the engine is running under its own power. The long exhaust pipe 11 has an outlet 24 which is additional to the exit nozzle and is located adjacent the inlet end of the pipe 11, said outlet being controlled by an unbalanced valve 18 which is held in the open position by a spring 22 attached to a lever 21 mounted on the spindle 20 of the valve. As soon as the pressure in the pipe 11 rises above a pre-determined figure, it acts on the unbalanced valve 18 and closes it against the action of the spring 22. If desired, the valve 18 may be opened and closed by an electric motor operated in conjunction with the starting system. The valve 18 is mounted in a trunk 19 which is attached to the pipe 11 and nacelle 6 by spherical joints 25, 26 and 27, 28 to allow for expansion. The flange 25, Fig. 4, is attached to the pipe 11 by spherical headed bolts 31 which engage keyhole slots 30 in the flange. A projection 29 on the flange 27 engages a lug 23 on the trunk 19 to prevent the trunk turning and disengaging the joint 25, 26. The flange 27 may be removed to allow the trunk 19 to pass through the nacelle 6. The Provisional Specification refers to preventing resonance in the jet pipe at starting by the introduction of cooling air.

Abstract: 1,086,336. Automatic voltage control. GENERAL MOTORS CORPORATION. Aug.4, 1966 [Sept.15, 1965(2)], No.35005/66. Heading G3R. A voltage regulator 10 for an alternator 12 having a stator 14, a field winding 16 and an output rectifier 18 comprises a first switching circuit 26 connected to control the excitation current in the winding 16 and a second switching circuit 28 which controls the operation of circuit 26 in response to output voltage variations as detected by a circuit including a voltage divider 58, 60, 62 and a Zener diode 56. The circuits 26 and 28 each comprise a pair of NPN transistors interconnected as shown. When the output voltage is below a desired value the Zener diode 56 is non- conducting, the switching circuit 26 then being so biased that it conducts to allow the flow of field current; the output voltage thus increases, and when it exceeds the desired value the Zener diode 56 conducts and biases circuit 28 to conduction. whereby circuit 26 is rendered non-conductive and the field current is reduced. This cycle is repeated to maintain the output voltage constant at the desired value. The voltage divider may include a thermistor Fig. 2 (not shown). The inherent capacitance of the Zener diode 56 and the resistance of the circuit connecting the Zener diode to the voltage divider may be utilized to constitute an RC circuit for attenuating the alternator ripple component and the ringing component introduced by the junction capacitance of the rectifier diodes 18, thus preventing the regulator from bein triggered by these components. The regulator 10 may comprise one or more monolithic silicon blocks fabricated by an integrated circuit technique.
