Abstract: 131,273. Du Pont de Nemours & Co., E. I., (Assignees of Baker, T.). Aug. 8, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Workshops and plant, arrangements of; varnishes. - Volatile solvents are recovered from coated surfaces, such as split hides and aeroplane wings by passing a current of air over the surface and passing the vapour-laden air through an absorbent consisting of " dead oil," i.e. a coal tar distillate boiling at 240-350‹ C. The coated surfaces are run on a truck 5 into a drying-chamber 1 heated by a steam coil 2. Solvent-laden air is withdrawn through outlets 10, 11 and is led by a pipe 12 to a cooler 10 and thence to an absorbing- tower 18 in which it is passed repeatedly through a counter-current of an absorbent liquid. The vapour-freed air is withdrawn through a pipe 23 by a pump 24 and may be returned to the drying- chamber by the openings 3, normally used for inspection purposes. The wheels of the truck 5 run between rails 7. The coating-table 8<b> may have hinged sides 8<c> which are used to prevent heavy vapours from streaming down to the floor. As the coating proceeds, the truck is gradually pushed into the drying-chamber, air being meanwhile sucked into the chamber through the door 4. A dope for coating aeroplane wings consists of nitrocellulose dissolved in a mixture of butyl acetate, benzol, and ethyl acetate.

Patent GB-133311-A (GB)
IPC: A61M1/08
Abstract: 133,311. Morse, R. V. Oct. 2, 1918, [Convention date]. Magnetic speed indicators operating by sighting aerial objects. -Relates to anti - aircraft sighting-devices having means for correcting for the speed of the target and consists in apparatus, shown diagrammatically in Fig. 1 comprising a primary sight 5, mounted to move with the gun and set for tangent angle of elevation only, and a secondary sight 6, which is the sight used by the gunlayer, capable of being set at an angle to the primary sight to correct for the speed of the target. This setting is indicated at the primary sight. The gun - layer at the secondary sight 6 elevates and trains the gun to keep the sight on the target, and the observer at the primary sight 5 operates mechanism 7, 8 for angularly setting the secondary sight. In the construction shown in Fig. 2 the primary sight has fixed cross-wires 10, the intersection P of which represents the point of impact of the shell, and movable cross-wires 11<1> mounted in a frame 11 adjustable horizontally and vertically by hand wheels 7, 8 which also operate the mechanism for setting the secondary sight 6 so that the lines of sight defined by the movable cross-wire 11<1> and by the secondary sight 6 respectively are always parallel, and when the gun is laid to keep the sight 6 on the target, the target is kept on the movable cross-wires 11<1>. The duty of the observer at the primary sight is to operate the cross-wires 11<1> so that the target is heading towards the centre P, and is at such a. distance from it that during the time interval of lead the target would reach the centre P. The horizontal and vertical leads may be automatically determined and continuously indicated in the field of view of the primary sight by apparatus shown in Fig. 3. In the body 5 of the telescope is a vertical wire or strip 30 on which is thrown a spot of light which is adjusted by magnetic speed indicator mechanism mounted in a casing 41. A ray of light is reflected bv a fixed mirror 33 through a helical slot 35 in a cylinder 34 and through a vertical slot 32 in a partition in the casing. The cylinder is capable of rotating against the torsion of a spiral spring 48, under the influence of a magnet 46 which is rotated at a speed proportional to the vertical component of the angular speed of the target, by mechanism connected to the elevating-gear of the gun, and is raised into the cylinder a distance proportional to the time of flight by mechanism connected to the fuse-setting apparatus, so that the resultant position of the cylinder, and consequently of the spot of light on the strip 30, indicates the vertical lead. The horizontal cross-wire is operated in accordance with this indicaiton. Similar apparatus is provided for the horizontal lead. Two separate secondary sights may be provided for training and elevating respectively. The apparatus may be arranged as separate mechanism not combined with a gun. Specifications 133,307 and 133,308, [both in Class 92 (ii), Ordnance &c.], are referred to.

Abstract: 1,134,223. Disc brakes. GIRLING Ltd. 28 March, 1966 [3,0 March, 1965], No. 13343/65. Heading F2E. In a pivotally-mounted caliper disc brake, brake pads 18, 20 are adapted to be urged into frictional contact with the brake disc by a mechanically movable thrust member 22 which acts on at least one brake pad 20 through the intermediary of a resiliently deformable body 30 constituting a force-multiplying element which is deformable to effect braking engagement without being subjected to shear force. In the embodiment shown in Fig. 3 the main brake is actuated by opposed piston and cylinder units 14 which urge pads 16 of friction material against the brake disc. The thrust member 22 is acted upon by a pivoted actuating member 24 to actuate the resiliently deformable rubber block 30 against the friction pad 20 and, by reaction on the pivotally mounted caliper housing 10, the pad 18 which is fixed in the caliper member 10 is adapted to be brought into contact with the opposite face of the brake disc. Adjustment for wear of the mechanically actuated brake is provided by means of a grub screw 32 associated with the indirectly operated pad 18. An automatic adjusting mechanism for the hydraulically actuated brake is provided by a compressible ring 28 which embraces each piston 15 such that, when the fluid pressure is removed, the ring 28 grips the piston and prevents it from retracting any further than is permitted by the natural tendency of the ring to recover its original shape. An alternative embodiment is disclosed in the Specification in Figs. 5 and 6 (not shown), wherein fluid motor means and the mechanically movable member act independently on the same brake pads through a force-multiplying element.

Abstract: 133,859. Martin, E. Jan. 8, 1919. Cased or compound forms; wire; tubes.-Wire and tubes formed of a teel foundation and an outer layer of copper, tompac, nickel, silver, brass, or other alloy, are constructed by surrounding hollow or solid steel billets with a cylindrical compound jacket, the outer layer of which is of the required metal, and the inner layers of which are formed of composite layers of metal adapted to form a brazing connex on with the billet. The whole is then united by heat and compression and subsequently rolled and finished by usual means such as drawing. In carrying out the process, the billet is ground, cleansed by potash, and subjected to a coppering bath. The cover is obtained by hammering, polishing, and rolling a mass of copper to a thickness of e.g. 35 millimetres, and to the interior of this plate is applied a composite layer composed of copper and brass, with 20 per cent of a metal having a lower fusing point such as silver, and 1 to 2 per cent of a metal having a higher fusing point such as nickel, which is intended to form a brazing between the steel and copper, and to the outside of the plate is placed one or more thin sheets of the metal or alloy intended to form the outside of the tube or wire, its thickness being a tenth of a millimetre. The composite layer is preferably composed of two plates of brass of 2 to 3 millimetres thickness between which are placed a layer of 5 millimetres of an alloy of copper with about 3 per cent of nickel, and a sheet of silver half a millimetre thick. The composite layer is rolled to a thickness of about a third of a millimetre before being applied to the copper, and the whole is then welded in a hydraulic press, rolled to a thickness of 10 to 15 millimetres, cut into disks which are stamped into tube blanks and' drawn to the correct size to place around the steel billet, and made of such thickness that the percentage of copper, brass, &c., to steel is from 3 to 6. The combined billet and covering is heated in a furnace and compressed and welded preferably in the press described in Specification 128,927, [Class 87 (i), Bricks &c.], and is subsequently rolled, drawn, and annealed, a core being employed when tubes are being made.
