An adhesive may be applied as a foil or coating between the metal and the core. In examples, aluminium sheets and paper cores are continuously laminated by heat and pressure as follows. (1) Three webs of paper are impregnated with phenol-melamine resin solution, dried and bonded as a core between the facing sheets using adhesive foils of gum-modified phenolic resin. (2) The core is constituted by six paper webs including natural resin which have been coated with synthetic rubber latex after manufacture, and the facing sheets are coated with gum-modified phenolic resin adhesive. (3) Facing sheets F (one of which is anodized), binder foils B of polyethylene, adhesive foils A of ethylene-acrylic acid copolymer and paper sheets P are bonded in an assembly FAPBPBPBPAF. (4) Two papers are impregnated with phenolic resin during manufacture, dried and bonded as a core between facing sheets coated as in (2).

Patent GB-1049743-A (GB)
Title: New active substances and their manufacture
IPC: C07D259/00
Filed: 1963-06-11
Abstract: The invention comprises ferrirubin and desferrirubin, which are prepared by cultivating under aerobic conditions in aqueous nutrient solutions containing sources of nitrogen and carbon and mineral salts, Penicillium variabile M2733, Spicaria sp. M4622 or Paecilomyces varioti M4646.  Preferably the iron content of the nutrient solution is at most 10-7 mol./litre. The compounds may be extracted with adsorbents or by solvent extraction. Desferrirubin is formed as well as ferrirubin and may be converted to ferrirubin by addition of ferric chloride.  Ferrirubin may be catalytically hydrogenated to form hexahydroferrirubin. Ferrirubin and hexahydroferrirubin may be converted to desferrirubin and desferrihexahydroferrirubin by reaction with a base or an acid or a substance capable of forming iron complexes. Desferrihexahydroferrirubin may be deacylated by mild acid hydrolysis to form a cyclic hexapeptide, which may be acetylated and the O-acetyl groups selectively split off to form desferrichrysin. Examples are given.  Pharmaceutical preparations for the treating of anaemia and for combating the anti-bacterial effect of antibiotics belonging to the sideromycin group towards gram-positive pathogens, comprise the compounds of the invention with carriers, e.g. gelatine, lactose, glucose, sodium chloride, starches, magnesium stearate, talc, vegetable oils, benzyl alcohols, gums, polyalkylene glycols and cholesterol.

Filed: 1929-07-30
Abstract: 328,518. Bowie, M. C. July 30, 1929. Pencil holders.-A pencil holder consists of a member C adapted to receive in its open end a split sleeve A in which the lead is slidable, the point of the lead projecting through an aperture in the end of a cover D adjustable on the member C. The cover D may be formed with a split open end to render it resilient, the fingers being forced into engagement with the member C by a ring. The sleeve A encloses a rubber sleeve serving to hold the lead more securely. The sleeve A is preferably formed from a rectangular blank of metal rolled into cylindrical form with the ends overlapping so that the lead can be easily adjusted forwards or backwards by rotation in one direction but binds in the sleeve if rotated in the opposite direction.

Title: Improvements in gun-sights for moving targets
IPC: F41G3/00
Filed: 1933-08-22
Abstract: 409,188. Anti-aircraft gun sights. AKT.-GES. C. P. GOERZ, OPTISCHE ANSTALT, Pressburg, Bratislava, Czecho-Slovakia, and PETSCHENIG, K., 5, Sonnleithnergasse, Vienna. Aug. 22,1933, No. 23365. [Class 92 (ii).] Relates to ring sights B, shown in plan, which are maintained horizontal during the elevation of the gun g, the radius of the ring corresponding to the estimated velocity of the target and the distance of the centre M of the ring from the lower sighting mark K being adjusted in accordance with the mean velocity of the projectile dependent on the range. According to the invention, a known form of adjustable ring sight in the form of an iris diaphragm is horizontally pivoted at 2 on a sight carrier 1 and kept horizontal by linkage 4, 5, connected to a fixed arm 6 on the gun carriage. Further, the ring 3<a> of the diaphragm is adjusted to vary the radius of the ring to suit a target velocity scale, and the sighting mark K is adjustable along the sight-bar to suit the mean projectile velocity. To prevent the target being obscured by the diaphragm, the sight line is displaced laterally by an optical device 8 comprising an opaque mirror 9<b> and a transparent mirror 9<a>, the device being horizontally pivoted in a member 10 slidable in a slot x in the sight-bar and controlled by a rod 11. The slot x is shaped to give the adjustment for tangent angle of elevation dependent on the range and angle of site of the target. When the ring B is used as a backsight instead of a foresight as shown, the optical device 8 can be dispensed with. In carrying out the invention in connection with telescopic sights, a projection lens as described in Specification 399,751, [Group XX], is employed.

[Class 83 (i)] Mould-coating apparatus as described in Specification 423,612 is provided with an additional nozzle 10 by which gas carrying powder is directed against the end portion 2 of the mould 1 when the apparatus is in the starting position. After a core, not shown, has been inserted in the bell mouth 2 the apparatus 6, Fig. 2, for supplying gas carrying powder is started and regulated by either of the switches 30, 31 and when the end portion of the mould is coated sufficiently metal is poured into the runner 25. When the bell portion is filled with molten metal the mould is traversed towards the left and a finger 24 trips a switch 23 which causes electromagnetic means 20 to move a valve 16 and direct the supply of gas &c. to the main nozzle 9 instead of the nozzle 10 so that the remainder of the mould is progressively coated during casting. If desired, the apparatus 6 may be turned off after the bell 2 has been coated and until the mould traverse is started. In a modification the mould is stationary and the runner &c. traversed.
