Title: Improvements in and relating to Means for Stopping the Delivery of Roving in Spinning Machines.
Inventor: SHARP PETER
IPC: D01H13/18
Filed: 1918-01-28
Abstract: 125,682. Sharp, P. Jan. 28, 1918, Delivery, stopping; thread-guides.-The roving passes through a guide 4, Fig. 1, at the end of a spring-controlled lever 1, between the rollers 5, 8, and under the feeler 11 to the flyer 9. When the roving breaks, the lever 1 is released and the roving moved into the groove 7 on the rollers 5. The feeler 11 is pivoted at 12<a> in a casing 3 and is substantially balanced. Its upper end carries a latch 14 engaging under a plate 18 on a pivoted piece 19. When the end breaks, the feeler 11 falls and raises the member 19, until the latch 14 escapes from under the plate 18, when the member 19 falls back, and a pin 21, Fig. 5, on its upper end engages a spring-held trigger piece 22, and releases a pivoted catch 24 from a snag 27 on the lever 1, allowing the lever to move about its pivot 2. The raising of the member 19 releases a weighted tumbler 30 from the abutment 28 on the member 19. To restore the parts to their operative position, the lever 1 is moved. back by hand. A catch 31 on the lever forces over the tumbler 30 and thereby raises the member 19. The lever 1 is locked again by the catch 24 engaging the snag 27. The plate 18 on the member 19 is slightly curved at its ends to facilitate the sliding off, and the bringing to rest of the latch 14 on the feeler 11. The mechanism is put out of action for doffing purposes when the frame is stopped, by spring plungers 41 operated by cams 40 on a hand-operated rod 42 and adapted to engage the tumblers 30. The feelers 11 can all be simultaneously lifted past their normal position and then lowered to engage the threads on the re-starting of the frame by means of a series of cams 45 on a rod 44 which engage levers 46 with bowls 48 acting on the feelers. The usual thread-guide between the rollers 8 and the fliers 9 is dispensed with and a guide formed in the end of the arm 12 on the feeler 11.

Title: Heating liquids by direct contact with hot gases
Inventor: SWITZER ROBERT LELAND
IPC: F22B1/26
Filed: 1963-01-14
Abstract: 973,465. Evaporating liquids; concentrating phosphoric acid. UNION OIL CO. OF CALIFORNIA. Jan. 14, 1963, No. 1642/63. Heading B1B. Corrosive liquids, such as aqueous phosphoric acid, are concentrated by passing the liquid through line 14 into zone A of crucible 5 where the liquid is mixed with hot combustion gases discharged from nozzle 4, having a convergent/ divergent passageway 10, at the lower end of a dip tube 3 which contains a fuel burner 11 disposed so that the flame of burner does not impinge on the nozzle. The mixture of hot gas and liquid flows up annulus B, and enters detrainment zone C. The concentrated liquid is withdrawn through lines 26. The gas stream, containing water vapour, passes out through line 17 where it is washed by water spray 18 and passed through baffles 20, to remove large droplets of entrained liquid, the gases are then treated with a further water spray 23, and passed to the discharge-stack via a series of annular discs 28 made of felt or glass fibres. Separated liquid is withdrawn through lines 21 and 24. The lower portion of the nozzle 4 is cooled by passing cooling fluid through an annular chamber 9 in the nozzle. Fuel, such as producer gas, water gas, Diesel oil or kerosene, is supplied to the burner 11 through line 12, and the fuel is ignited in air or oxygen by a spark means through ignition wire 32. The temperature of the combustion gases is controlled by introducing cool air or recycled stack gases through line 25. When used for concentrating phosphoric acid, the temperature of the combustion gases is regulated to between 1000 and 2000 ‹F. prior to contacting the acid. The temperature of the acid in annulus B is maintained at about 430 ‹F. by controlling the feed-rate of the acid. Crucible 5 and dip-tube 3 may be made of graphite. The upper end of the metal shell is protected by a liner made of graphite, polyethylene, polytetrafluoroethylene, or epoxy resin. The treatment of sulphuric acid and salt solutions is mentioned. If desired, the lower part of the nozzle may be made of material which is permeable to the cooling fluid, so that the cooling fluid diffuses into the nozzle passageway and exerts a washing action.

Abstract: 582,892. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 31, 1944, No. 1725. Convention date, Jan. 30, 1943. [Classes 39 (i), 40 (iii) and 40 (v)] [Also in Group XXXV] A grid 14, Fig. 1, is placed in the path of an electron beam 17 and connected to an external circuit of a television transmission tube so that electric pulsations are produced on the grid or on the picture signals of a frequency depending on the scanning speed of traverse of the electron beam and this frequency is compared in tho circuit with a standard frequency to produce a correcting bias if the frequencies differ, the bias being applied to the scanning circuit to ensure uniform scanning speed. The grid 14 may comprise a single set of strands 18 in front of the usual mosaic 15 ; or, as shown in Fig. 3, the grid may comprise two interlaced sets of strands 79, 81, and a -capacity screen 70 is interposed between the grid and the mosaic 82. The pulsations produced on either of the two sets of strands 79, 81 may be used singly or in combination. In the circuit shown in Fig. 1, the frequency of the produced pulsations is compared with the frequency to which a resonating circuit 38, 39 is tuned, and a difference berween these frequencies causes a double diode combination 46, 47 to produce a voltage bias in one direction or the other between the outer ends of a resistance 43. This bias is fed into the grid circuit of an amplifier 52 in the circuit transmitting the scanning control to the cathode-ray tube.

[Class 39 (i)] In a television transmitting tube in which a mosaic screen is scanned by a cathode ray to generate picture signals, and wherein a connecting signal is applied to reduce the effect of " tilt," the correcting signal is made more constant, despite rapid changes in the brightness of the image, by generating in the tube electrons having a speed of the order of the emission speed of photo-electrons, these electrons being additional to photo-electrons which may be emitted from the mosaic or by the scanning beam. The slow-speed electrons may be generated thermionically or by projecting light on to a photoelectric surface, such as an anode, from a filament, which is arranged behind the mosaic and is energized by D.C. or A.C. The mosaic may be light sensitive, or a separate photo-cathode may be provided, and the slowspeed electrons may be generated continuously or intermittently between successive frames.

Title: Improvements in or relating to coating compositions
IPC: C08L61/14
Filed: 1942-02-13
Abstract: Film-forming materials are obtained by heating a fatty acid derived from a drying or semi-drying oil with an oil-soluble phenol formaldehyde resin derived from a phenol having an alkyl substituent in the position para to the hydroxyl group.  Specified oils are soya bean, oiticica, linseed and perilla, and specified phenols are p-cresol, p-tertiary butyl phenol and p-tertiary amyl-phenol.  The phenol/aldehyde ratio may be between 1/2 and 2/1 and the ratio of resin to oil acid conveniently 1/2 and 1/3 .  Heating of the resin and oil acid is effected at about 275 DEG  C. and is continued until the acid value of the system falls as low as possible, generally to about 80.  The products may be incorporated with solvents, thinners, drying oils and/or pigments to form varnishes &c.  They may be blended with other synthetic resins.  In examples: (1) an oil-soluble resin, derived from one mol. of p-tertiary butyl phenol and two mols. of formaldehyde, is heated with three parts by weight of linseed oil fatty acids; (2) a similar resin is heated with 4 parts of linseed oil fatty acids, first at 210-220 DEG  C. and then at 275 DEG  C.; the product may be thinned with xylol to form a coating composition, or may be employed to plasticize an aminoformaldehyde resin, e.g. such as is described in Specification 483,399.  The coating compositions may be applied, both as air-drying and stoving finishes, to surfaces of metal, wood or paper; as insulating finishes for electrical conductors, and, blended with urea-formaldehyde resins, as adhesives in the manufacture of abrasive sheets.
