Title: Improvements in or connected with the construction of cantilever wings and other aircraft structures
IPC: B64C3/18
Filed: 1934-07-28
Abstract: 431,895. Aircraft structural members. SHORT BROS. (ROCHESTER & BEDFORD), Ltd., and GOUGE, A., Seaplane Works, Rochester, Kent. July 28, 1934, No. 22090. [Class 4] Framework.-A spar for cantilever wings or other aircraft parts comprises cruciform section booms A, B, C, D, Fig. 3, each having two horizontal flanges and a vertical web above and below, the booms being interconnected by bracing members. In each boom the inwardly extending web part a<3> is of greater length than the outer and provides attachment by gusset plates to tubular struts b, b<1>, as shown in side elevation in Fig. 1. Transverse and diagonal struts c, cl, Fig. 6, are similarly attached to inwardly extending flanges a, a<1>, Fig. 3. Each transverse panel is braced by crossed members d, d<1> secured as shown in Fig. 7. The booms which may be extruded sections of the material known under the Registered Trade Mark " Duralumin " or of other light alloy or steel may be progressively reduced in weight from root to tip of the spar by milling the corners of the sections in successive stages ; thus the boom section may be changed at e, Fig. 1, from that shown in Fig. 4 to that shown in Fig. 7. The length of the web or breadth of the flanges may also be varied. In a modification the booms are built up from two T -sections or four angle sections riveted together in such manner as to produce a cruciform boom. The arrangement of the diagonal members connecting the booms to each other, Figs. 1 and 6, is such that bending stresses on the spar due to lift forces and torsion due to aileron operation is taken in tension. Ribs f, Fig. 6, may be secured to outwardly extending web parts a<2>.

Title: Improvements in and relating to photo-sensitive material
IPC: G03C7/06
Filed: 1931-08-04
Abstract: 383,311. Photographic plates &c. ; colour photography. AMIRA TRUST, Vaduz, Liechtenstein, and WELKER, J. P., 191, Rothenbaumchaussee, Hamburg, Germany. Aug. 4, 1931, No. 22141. [Class 98 (ii).] A photographic material, particularly for use in colour photography, comprises a transparent backing on which is an uncoloured, sensitized emulsion in the form of lines or particles with clear, transparent spaces. Two or more such films may be exposed one behind another with interposed colour screens to produce colour sensation records for the production of colour photographs. The emulsion may be sprayed on to the backing or may be mechanically printed thereon. Alternatively, the material may be produced by forming interstices in a layer of emulsion by stamping or by burning by heat or acids. Material for making diapositives may be produced by photographically printing a suitable screen pattern on to a sheet of emulsion, developing and removing the developed portions, e.g. by permanganate of potassium and sulphuric acid. The material may also be produced by printing a coloured &c. resist and removing exposed portions chemically, the resist being finally removed by suitable solutions.
Patent GB-811265-A (GB)
Title: Improved height control system for motor vehicle pneumatic suspension
IPC: B60G17/052
Filed: 1957-07-12
Abstract: 811,265. Road-vehicle undercarriages. GENERAL MOTORS CORPORATION. July 12, 1957 [Aug. 24, 1956], No. 22141 /57. Classes 108(2) and 108(3) A height control system operable independently on each wheel of a vehicle comprises air springs for. each wheel each controlled by a valve for the supply of air to or from the spring the rate of flow of air being controlled by a master valve responsive to said flow. The system tends to keep the height constant under changes of load and during stopping, starting and cornering and the master valve prevents too rapid changes or hunting. A springs 25, 27, 31 each have a piston 58 connected by levers 44, 46 to a valve assembly 30 while the left front spring 29 has its pressure chamber interconnected with that of the right front spring 31 through a valve assembly 61. Each valve assembly 30 has inlet and exhaust valves 32, 34 connected by pressure and exhaust lines 40, 42 through a master valve assembly 66 to high and low pressure tanks 22, 24 controlled by a compressor 10 driven by the engine. A plate 52 in each valve assembly 30 is attached to a lever 44 and on compression of the spring opens the inlet valve 32 while of expansion of the spring opens the exhaust valve 34. In operation upon compression of a spring its piston 58 opens its inlet valve 32 to admit air from the high pressure line 40 to restore the original height of the spring. The air in the line 40 is drawn from the high pressure tank 22 through passages 90, orifice 72 and passage 92 in the master valve, and a line 40a. The passage 90 has a restriction 88 the flow of air through which causes a resiliently mounted plunger 70 to close an orifice 74 so that any air to be drawn from the low pressure line 42 has to pass through a passage 112 having a greater restriction 114. The master valve thus prevents rapid simultaneous supply and exhaust movements of air so that levelling proceeds positively without any valve hunting. On cornering or starting or stopping one pair of springs is subject to expansion and one pair to compression and the attempted flow of air to and from the springs will close both orifices 72, 74 thus restricting any flow so that there is little change of height after the normal ride position has been restored. Omission of a valve assembly 30 for the spring 29 is compensated for by the restrictions 62a, 62b in the valve assembly 61.

[Also in Division C7] In a process for coating substrates, especially metals, a radiation curable material is vapour deposited on the substrate and the deposited film is subjected to ionizing radiation under vacuum (e.g. 10<SP>-3</SP> to 10<SP>-5</SP> Torr.) to polymerize the material in the film. " Radiation curable material " is defined as any material which can be cross-linked by an accelerator electron beam, X-rays or γ-rays (and which may not be capable of cross-linking by chemical means), which has a vapour pressure at S.T.P. of < 1 Torr. Examples are low M.W. addition and condensation polymers, e.g. epoxy resins, unsaturated polyester resins and monomers, e.g. vinyl stearate. The ionising radiation may be an electron beam, e.g. of energy up to 20 KaV. The method is suitable for coating a continuous elongated substrate, e.g. strip or wire and the drawing (not shown) illustrates a suitable apparatus.
