Filed: 1970-08-18
Abstract: 1314348 Cathode-ray tube circuits RCA CORPORATION 18 Aug 1970 [20 Aug 1969] 39676/70 Heading H4T A circuit arrangment for correcting NORTHSOUTH and EAST-WEST pincushion distortion employs a saturable reactor 40 (Fig. 2) the two-part control winding 42a, 42b of which is connected in series with the vertical deflection coils 24a, 24b by means of a bifilar-wound split inductor 30 and a second two-part winding 44a, 44b of which it is connected at X-X in parallel with the horizontal deflection coils (not shown). In operation, NORTH-SOUTH correction is effected by modifying the vertical deflection current in deflection coils 24a, 24b as a function of the horizontal deflection current induced in control winding 42a, 42b by windings 44a, 44b, a voltage corresponding to such current being developed across the impedance network formed by capacitor 32 and resistor 33 and applied to the split inductor 30 which, with capacitor 26, forms a series circuit resonent at the horizontal frequency. The magnitude and phase of the correction current thus caused to flow in deflection coils 24a, 24b are adjustable by potentiometer 28 and by movement of the core of inductor 30 respectively. EASTWEST correction is effected by the variation in the inductance of winding 44a, 44b (which shunt the horizontal deflection coils) produced by the variation in core saturation of inductor 40 by the vertical frequency deflection current. The detailed manner of operation of the arrangement is described with reference to Fig. 3 (which shows the transductor core end windings indicated by the reference number of Fig. 2 prefixed by the numeral 3) together with explanatory waveforms and a phase diagrams (Figs. 4a ... 4d and Fig. 5, respectively, not shown). The transductor 40, inductor 30 and the associated resistors and capacitors may be mounted on a printed circuit board carried by the deflection yoke of the tube (Fig. 6, not shown).
Patent GB-346386-A (GB)
Title: Improvements in or relating to the treatment of grainy material
IPC: B65D88/74
Filed: 1929-12-31
Abstract: 346,386. Drying granular material. EDHOLM, H., Solsidan, Saltzjobaden, Sweden. Dec. 31, 1929, No. 39887. Convention date, Jan. 2. [Class 34 (ii).] Humid grainy material is dried by subjecting it to short drying periods, during which moisture from the surface layers of the grain particles is removed, interspaced by rest periods of several times longer duration than the drying periods, during which the moisture content of the grain particles can distribute itself evenly before further drying, and during which the grain is not subjected to drying air or to artificial heating. This drying process is carried out in a. vertical silo shown partly in section in Fig. 4, in which are arranged at different levels a number of drying zones. The grain is delivered to the bin 6 by a pneumatic elevator and passes down through the first drying zone which consists of a series of parallel sloping plates 8 with adjustable fillets 9 at their top edges, to regulate the flow of grain through the zone. The angle of the plates is adjusted to be slightly greater than the angle of repose of the grain so that a triangular space 10 is formed below each plate through which the drying air is passed. The grain then passes into a space 11 in which practically no drying takes place and the moisturecontent becomes evenly distributed before the grain passes into the next drying zone which is formed by inverted V-shaped beams 12, which may havea series of baffles on their under sides to cause the air to travel over the grain in a zig-zag manner. The grain falls between these beams in thin streams, and air from the channels 13 passes outwardly against the grain through the holes 14. Further drying zones 16, 19, 23, 26 are provided, spaced by zones 15, 18, 22, 25 in which no drying takes place. In the lower drying zones the areas of the air channels are made progressively smaller. The outlets 28 at the bottom of the silo are fitted with pivoted tables 29 ; when these are stationary no grain flows from silo but when they are rocked by means of the rod 31 grain will flow through into the receiver 32 from which it can be returned if necessary to the top of the silo. The electric motors that drive the fans which supply the air for drying and the air for the pneumatic elevator are connected to the electric supply through a switch operated by a relay controlled by a hygrometer so that drying is only proceeded with when the humidity of the air is above a certain value. Cold air is used, but it may be preheated in damp weather. The Specification also describes several other forms of drying zones, which are shown in Figs. 6. 7, 9, 10, 11. In the arrangement shown in Fig. 9, the slope of the plates 49 may be adjusted simultaneously, in that shown in Fig. 10 the plates 53 are adjustable, and in that shown in Fig. 11 the plates 55 are adjustable. These adjustments have the effect of varying the cross section of the air passages.

Abstract: 869,638. Contacting gases with liquid. FLUOR CORPORATION Ltd. Dec. 23,1957, No. 39919/57. Class 55 (2). [Also in Group XIII] Water passes from a header 21 to branches 22 to be sprayed from nozzles 14 over grid packing 16 and is cooled by air drawn up by a fan 23 in a top stack 24, through side louvres 15 and the packing 16 at up to 2200 feet per minute and then through inclined water-detraining baffles arranged in three annular layers 31, 32, 33. The baffles, which are inclined transversely in opposite directions in successive layers, Fig. 2, at an inclination which may vary from layer to layer, direct the air into the fan 23, in a spiral course opposite to the direction of fan rotation. A longitudinal groove 40, near the lower edge of each baffle, conducts the detrained water to a central conical support 36 mounted on a tubular column 35 (supported from the floor 18 of the cooling tower or from the water distribution system). It flows into a ftmnel 37, whence it may overflow or pass into the column 35 and out through a bottom opening 39 on to the floor 18. A pump 19 passes the water back to the top header 21. The top baffles 33 are said to be only so wet on their undersides that the moisture is not re-entrained by the air. A motor 25 drives the fan 23 through a gear assembly 28 supported by the tubular column 35.

Abstract: 1404758 Truing spoked wheels RALEIGH INDUSTRIES Ltd 22 Aug 1972 [25 Aug 1971] 39953/71 Heading B7C A method of truing a wheel subsequent to fitting spokes 16 to the wheel hub and loosely screwing spoke nipples 26 mounted in the wheel rim 15 to the spokes comprises the steps of clamping the hub and rim with the hub offset relative to the rim such that some of the nipples. 26 project from the rim 15, and tightening the projecting nipples by rotating the clamped wheel relative to resilient band means, e.g. 19, 22, which contact the spoke nipples and rotate them on their spokes. The hub and rim may be clamped with the hub initially centralized relative to the rim, the thus clamped wheel then being rotated relative to the band means to partially tighten all the spoke nipples 26. The hub may be offset axially relative to the rim, or may be offset angularly by rotating the hub relative to the rim, and in these instances offsetting may be effected first in one sense and then in the opposite sense, tightening of projecting nipples being effected after each offsetting action and the process being repeated, if necessary, until the wheel is true. Alternatively the hub may be eccentrically offset relative to the rim. In the apparatus for carrying out the method shown in Figs. 1 and 3 the rim is clamped by horizontally or vertically mounted annular platens 10, 13, respectively having a rim retaining flange 11 and a rim receiving groove 14 and being movable towards and away from one another. At the centre of each platen 10, 13 is a hub clamping and hub spindle receiving device 12, appropriate means to move the latter being provided according to whether axial, angular or eccentric offsetting of the hub is desired. Means for centering the hub relative to the rim may also be provided. The resilient band means are mounted on a carrier 17 movable towards and away from the platens 10, 13 and comprise a movable endless band 19 and an endless band 22 fixed to non-rotatable members 23 on the carrier. The band 19 is mounted on pulleys 18 connected to knurled wheels 20 whereby when the wheels 20 are brought into contact with a friction surface 21 on the platen 10 and the platen 10 is rotated the band 19 is driven. The ratio between the diameters of the wheels 20 and pulleys 18 may be 1: 2.
