Title: Improvements in or relating to rigid airships
IPC: B64B1/58
Filed: 1926-10-12
Abstract: 282,518. Airship Guarantee Co., Ltd., and Wallis, B. N. Oct. 12, 1926. Aerostats.-The outer cover of a rigid airship is stretched across the ridges formed by the longitudinal girders and is then pulled inwards by lacing it to initially taut circumferential mesh wiring disposed between the cover and the shear wires of the framework. The framing shown consists of triangular girders with tubular corner booms a secured to similar transverse rings as described in Specification 282,167, the apices of the girders projecting outwardly beyond the transverse rings. A series of clips D is secured over the outer booms a, the clips having eyelets at their inner ends through which pass the wires B of an initially taut mesh wiring. The panels of the fabric covering I are also taut laced to each adjacent panel with or without the catenary system described in Specification 280,670. A series of circumferential or longitudinal tapes E is provided on each panel, and cords F passed through eyelets in these tapes and under the wires B, are drawn tight to draw the already taut cover and mesh wiring towards one another as shown. Variations of contour in the outer fabric are thus prevented without deforming the main shear wiring.

Abstract: 269,256. Mount, W. D. Oct. 13, 1925. Pulp, preparation of. - In the production of wood pulp black soda ash is leached and lime is slaked concomitantly in the same liquid, the mixture is continuously causticized, the causticized product is separated into clear liquid and sludge, and the wood is treated with the clear liquid to produce pulp magma. The black ash, lime, and slaking liquid are introducing into the slaking pot 6 and from thence to the oausticizer 10, the caustic liquid being passed through a decanter 30 to separate the sludge, and the clear liquid being removed through a pipe 31 to a storage tank 32 and digester 34. The sludge is delivered to a filter 43, the solid matter, comprising calcium carbonate and carbon, being removed to a rotary kiln 3 for calcination, and the resultant lime is deposited upon a conveyer 2 which takes it to the slacking pots 6. From the digester 34 the pulp and caustic liquid are conducted to a tank 36 and separated by a rotary filter and washing device 37, the separated liquid passing to an evaporator 39 and thence to rotating furnaces 1 wherein it is converted into black ash and deposited upon the conveyer 2. The causticizer preferably comprises a vertical casing 11 containing a number of reaction pans 12, each provided with an upwardly extending flue 13 and a mushroom head 14, an overflow pipe 15 being connected to each of the upper pans. The mixture from the slacking pots 6 is fed into the highest pan and steam or hot air is blown in through a pipe 17 at the bottom. Additional alkali liquid may be added to the causticizer, the liquid, which may be cooled by passing it through a condenser, being fed into an annular trough 22 above the highest pan.

Abstract: 1506749 Cathode-ray-tube circuits SONY CORP 18 June 1975 [20 June 1974] 25967/75 Heading H4T Apparatus for correcting misregistration of electron beams on the colour phosphors of a colour C.R.T. due to thermal expansion and distortion of a selecting structure (e.g. shadow mask) through which the beams pass, the apparatus comprising coils 8a-8d adjacent the neck 3 of C.R.T. 1 for producing magnetic fields, a first circuit for supplying a correcting current to said coils the current varying according to the temperature of the beam selecting structure, and a second circuit for supplying a current to the coils which varies in a predetermined manner during the initial period of operation of the tube. As described, the temperature sensitive element of the first circuit comprises a thermistor 12 mounted on a printed circuit board to measure the ambient temperature of the C.R.T. and a thermistor 13 mounted on a deflection yoke 5 which is in thermal contact with the beam selecting structure. It is said that the yoke 5 does not change temperature until approximately 5 minutes after the C.R.T. is switched on, that is the change in temperature of the yoke lags behind the beam selecting structure. It is said that the electron drift D 1  after 5 minutes is half the maximum, steady value drift (Fig. 3, not shown) and the compensation due to the current in the first correcting circuit maintains the drift at D 1 . The second circuit 29 provides a current varying in a predetermined way for the first 5 minutes of operation to maintain the drift equal to D 1 , the current being passed through the coils in the opposite direction, and being reduced to 0 during the 5 minute period. The second circuit may alternatively comprise two thermistors in series (Fig. 6, not shown) whose resistance increases with time when a current flows.

The feeder(s) to the upper of two vertically displaced aerials, the lower one of which is a crossed-direction-finding aerial, are guided by a vertical frame surrounding the latter. In an embodiment the mast head 2 of a ship carries a V.H.F. direction-finding system including eight aerials 1 connected in parallel in pairs; a lower frequency direction-finding system includes pairs 3, 4 of ferrite rods and an auxiliary aerial of two frusto-conical or frusto-pyramidal linings disposed above and below the plane of the frames. A crossed frame with tubular frames 5, 6 guides the feeders to the V.H.F. directionfinder, the planes of the frames being aligned parallel to rods 3, 4. It is stated that directionfinding errors resulting from currents flowing in frames 5, 6 do not ensue. To reduce reduction in the sensitivity of the lower aerial system rings of ferrite 8 are arranged on frames 5, 6. The tubes of the latter are electrically connected to parts 9, 10. Frames 5, 6 may be utilized as a further direction-finder, coupling windings being on at least some of the ferrite rings, Fig. 2 (not shown).
