Title: Improvements in or relating to kite apparatus
IPC: B64C31/06
Filed: 1942-04-30
Abstract: 555,542. Pyrotechnic apparatus; aerial warfare. WHEELWRIGHT, K. S. April 30, 1942, No. 5797. [Class 9 (ii)] [Also in Group XXXIII] In kite apparatus for projecting and sustaining a line or cable by means of a rocket or pistol, the kite has a spring-controlled hinged frame whereby it may be folded and enclosed in a cover and be projected to flying height, the line being drawn or paid our during the projection and its tension acting to release the cover and thus permit the kite to open. The kite shown comprises a pair of booms b and a two-section transverse spar f, f<SP>1</SP> the outer ends of which are received in pockets al in the kite fabric. The sections f, f<SP>1</SP> are pivoted together at f<SP>2</SP> and their other ends are pivoted to runners b<SP>2</SP> slidable on the booms b. Elastic cords g attached to the sections f, f<SP>1</SP> and to the upper ends of the booms act to extend the kite frame. The kite cover h consists of two layers of fabric stitched together at h<SP>1</SP> so as to provide a series of longitudinal cells each of which receives a loop of the kite line e. The cover is rolled around the folded kite and its adjacent edges are secured together by a number of pins i that are passed through tubular members h3, h' attached to the edges. The line e is anchored at its lower end by an elastic cord e<SP>1</SP> to the dinghy &c. from which the kite is to be projected and at its upper part is attached to the pins i and to the kite. A further pin i<SP>1</SP> secures the line e<SP>2</SP>, j<SP>1</SP> of a rocket j to loops b<SP>3</SP> on the kite. When the rocket is fired, the tension in the line e effects the withdrawal one by one of the loops from the cover and finally of the pins i, il so that the cover and the rocket are detached from the kite which then unfolds. T he kite cover may instead be a metal cylinder acting as a projectile and the line may be unwound from a reel on the ground. The device may be used for raising a radio aerial or signal from an aircraft dinghy or for raising a kite barrage for defence against aircraft attack.

[Class 135] In a self-closing valve or tap of the kind comprising an axially-movable main valve spindle 10 the rate of return of which to its closed position is dependent upon the rate at which fluid is permitted to flow from the exterior of a dashpot chamber 6 to the interior through a valve-regulated passage in the spindle 10, the regulating valve 27 is mounted in the spindle 10 and is adjustable independently thereof, being readily accessible at the operating end of the main valve spindle 10 for this purpose. The main-valve washer 11 is secured against a shoulder on the spindle 10 by a collar 13 of slightly less diameter than the chamber 6 and co-operates with an annular valve seat 12 formed on a body member 4 screwed into the casing 1. The chamber 6 is screwed into the inner end of the member 4 and in it slides the collar 13 and also a cup washer 14 secured between the collar 13 and a suitably-shaped nut 15 screwed on to the end of the spindle 10. An axial bore 21 in the spindle 10 communicates through radial passages 22 in the spindle and an annular space 23 and radial passages 25 in the collar 13 with an external recess 24 in the collar which is in communication with the liquid supply through holes 8 in the chamber 6. A needle valve 27 is mounted in the spindle 10 to control the fluid flow through the bore 21, and has a threaded part 29 engaging a threaded part of the bore 21 for adjustment by means of a screw-driver inserted at the top of the casing. The valve 11 is opened against the action of a spring 17 and during this operation, liquid is forced from the chamber 6 through the passages 21 ... 23. Liquid can then flow past the valve 11 to the tap 3 through openings 8, 37. When the valve is released, liquid flows back through the passages 21 .. 23, the rate of flow being regulated bv the valve 27 so as to control the return of the spindle 10 to normal position. In place of the needle valve 27, a rod extending through the bore 21 may carry a conical valve member engaging a seating at the end of the bore 21. A screwed plug 31 closes the outer end of the bore 21 and a screw-on hood 32 of inverted cylindrical cup form with a coloured closure disc 35 is mounted on the end of the spindle.

Title: Improvements in and relating to the manufacture of sheet material from wood particles
IPC: B27N3/08
Filed: 1946-03-02
Abstract: In a process of making sheet material, wood particles of predominantly cellular structure which are large in the direction of the fibres and small in at least one direction at right angles thereto (e.g. wood shavings, wood wool) are mixed with a binder to a moisture-containing non-tacky composition, moulded, and cemented together under compression and under such heat that moisture evaporates, means being provided or afforded by which under the application of pressure vapours escape from all parts of the sheet to the effect that the composition is dried.  Water or organic solvents may be added to the wood particles to increase the moisture content, whilst the particles may be softened by pre-heating and compression before being cemented together, and wood dust should preferably be removed from the particles.  Other fibrous substances, e.g. asbestos, cotton waste, cork bark, hair, vegetable fibres, may be admixed with the wood particles; also rubber and bitumen.  Binders preferred are ureaformaldehyde resins and collagen-containing material (e.g. vegetable-tanned leather), which may be sprayed or dusted on to the wood particles or applied as a suspension in water & c.  Reference has been directed by the Comptroller to Specification 631,097.

[Class 94 (i)] A device for filling large paper bags or sacks comprises a rigid rectangular collar or frame of the dimensions corresponding to the transverse dimensions of a filled bag, and a flexible sleeve or skirt carried by the collar. The frame or collar α, Fig. 6, may be formed from a metal rod, or of wood, and to it is secured a flexible .sleeve b which may be of stout multi-ply paper. Each side of the sleeve has a flap f with sides converging to a free edge, a line of creasing g being provided to facilitate the folding of the flaps.  In use, the frame is placed over the mouth of an opened bag s, Fig 4, and adjusted until the crease lines g are at the level of the top edge of the bag. The flaps f are then folded inwards, and the bag is filled until the contents reach the level of the frame a. The frame confines the mouth of the bag and forces it to conform to a rectangular section; and the sleeve b and the flaps f maintain-the rectangular formation. Finally the flaps f are turned upwards, and the mouth of the bag is folded and secured by adhesive, as indicated in Fig. 6. In a modification, shown in Fig. 7, the frame is provided with a depending skirt or sleeve j which may be made of stout paper and folded to rectangular form corresponding to the shape of the frame. The skirt j thus forms a flexible packing-mould to shape the bag and contents to the described form. In some cases, the skirt may be of sheet metal instead of paper, and its length may be sufficient to support the greater part of the length of the bag. A footing or flange may be provided to receive the lower end of the skirt, or the sides of the skirt may be supported by bars.
