Title: Improvements in or relating to the continuous drying of filaments
IPC: D01D10/04
Filed: 1951-10-01
Abstract: 692,133. Drying, fibres, yams, &c. PHRIXWERKE AKT.-GES. Oct. 1, 1951 [Nov. 16, 1950; April 11, 1951; June 14, 1951], No. 22859/51. Class 34 (i) [Also in Group IX] In a method of drying filaments by passage through a drying chamber supported in convolutions on an endless conveyer 4 the filament 2 passes downward on to the conveyer through a current of gas moving in the same direction. The filament 2 passes over a guide roller 1 and downward through a guide shaft 3, which has a thread nozzle 5, on to the conveyer 4. Gas is blown or drawn through an inlet 6. into the shaft 3, carrying the filament in its current and depositing it on the conveyer, the formation of the convolutions being effected by lateral reciprocation of the conveyer belt or by reciprocation of the feed nozzle 5 or by the roller 1. Drying is performed by means of electric resistance heaters 10, 10<SP>1</SP>, 10<SP>11</SP>, and the velocity of advance of the conveyer is adjusted to correspond to the rate of drying of the filament, the dried filament leaving the chamber through a guide 11 and moisture laden air escaping through an opening 7. In a modification of the apparatus (Fig. 2) drying is effected by hot air which enters through a shaft 13, an insulating zone 14 preventing heating of the shaft 3, the lower part of which is cooled by cooling coil or the like. Cool moisture laden air is discharged through a shaft 15 by suction and a flap valve 6 can be operated to prevent air circulation in the front cool part of the apparatus and regulate the relative amounts of cold and hot air drawn in through shaft 3 and 13.

Filed: 1925-09-14
Abstract: 255,259. Wade, H., (W-H Keyless Lock Co., Ltd.). Sept. 14, 1925. Locks, permutation, in which separately-operated locking rings are arranged round a latchblocking bolt, have a common operating-means for latch-bolt and blocking-bolt, this means passing transversely through the blocking-bolt. The usual notched rings 16 are mounted on a slotted cylindrical sleeve 22 fitting in the part 20 of the bolt 19 and co-operate with lugs 21. The latchbolt 41 is operated by turning the spindle 37 by the knobs 38.

Abstract: 1,025,286. Colour television tubes. RADIO CORPORATION OF AMERICA. June 13, 1963 [July 9, 1962], No. 23690/63. Heading H1D. A scanning deflection coil system, particularly for a three-gun shadow-mask colour television picture tube, comprises saddle coils which conform to the tube neck and bulb and have parallel-sided window areas and in which the turns concentration shifts progressively in each coil, from the outer edge at the rear of the coil towards a more uniform distribution at the front of the coil. A more barrelled exit field is obtained at the front of the coil in order to reduce coma and astigmatism. The winding distribution is obtained by reducing the horizontal and vertical distance of the centre of curvature of the outer surface of each coil from that of the inner surface from rear to front of the coil.

Title: Pumping installations and a control arrangement for them
IPC: F04D15/02
Filed: 1964-06-08
Abstract: 1,063,849. Centrifugal pumps; hydraulic accumulators. SIEMENSSCHUCKERTWERKE A.G. June 8, 1964 [June 28, 1963], No.23728/64. Headings F1C and F1P. [Also in Division G3] When there is no demand for water in a domestic water pumping installation, Fig. 1, comprising a pipe system 5 and a pressure accumulator 6, a piston 10 in a housing 2 is held in contact with a seal 17 by a spring 11, and a conical valve 13, resiliently connected to the piston, is held clear of its seating 9 to permit the pump driving motor M to be switched off by a switch 7 operated by the pressure in the system 5 communicated to the switch through passages 8, 16. When water is tapped from the system, the fall in pressure closes the switch 7 to start the motor M. The pump delivers to the system 5 and thereby raises the piston 10 which closes the valve 13 and isolates the switch 7 in its closed position. When the water demand is such that the flow falls below a small critical value, the consequent lowering of the piston 10 opens the valve 13 and exposes the switch 7 to the substantially restored pressure in the system 5 with consequential stoppage of the pump. In another embodiment, Figs. 2 and 4 (not shown), the piston and associated valve are replaced by a conical valve (22) carrying on its upper surface a vertically extending needle (24) which, when the conical valve is raised by the pump delivery, engages the aperture (25) in a radially resilient ring connected to a plug (27) having a bore communicating with the switch, which plug is adjustably screwed into the housing (2) for regulation of the value of the small critical flow. Further, the pressure accumulator is connected directly to the housing (2) or is integral therewith and contains an air-filled elastic ball. In a further embodiment, Fig. 3 (not shown) the pump delivers to a pipe (29) containing a constriction (30) associated with passages (36, 37) communicating with a diaphragm chamber (32). When water is demanded the reduction in pressure downstream of the constriction (30) closes the pressure-operated switch (not shown) to start the pump, and the resulting pressure differential across the diaphragm closes a valve (35) to isolate the switch until the water demand falls below the critical value and the pressure differential across the diaphragm is thereby substantially eliminated. In a final embodiment, Fig. 5 (not shown) low pressure created by the withdrawing of water causes the pressure-operated switch (7) to start the pump (P), the delivery of which opens a butterfly valve (43) and closes a connected contact (45) on to a terminal (46). This maintains operation of the pump, irrespective of the position of switch, until the demand falls below the critical value when the butterfly valve is closed and the contacts (45, 46) are thereby opened.

The phosphate may be provided in a luminescent screen such as in Hg or Cd vapour lamps or in double coated c.r.t. screens. Excitation may be by X-rays, electrons, and short and long u.v. radiations. Emission wavelengths, half-bandwidths, &c. are disclosed for specific compositions, and also uses, such as in lamps for photochemical reactions, e.g. lacquer hardening and document reproduction, and with other phosphors for colour correction. Preparation is preferably by heating oxides or materials decomposing to oxides on heating (e.g. 900 to 1250 C. in a weakly reducing atmosphere). Heating may be in stages with intermediate grinding. A preheat is preferably 700 C. in air. Non-stoichiometric compositions are discussed, and detailed examples include preparations and specific phosphates. An excess of one or more constituents may enhance the formation reaction and/or grain properties. Fig. 2 (not shown) indicates temperature dependence for specific phosphors. Crystal structures are discussed.
