Title: Improvements in skeleton cores or bobbins
Inventor: DAVIDSON ERIC BROWN
IPC: B65H75/20
Filed: 1954-09-21
Abstract: 766,926. Bobbins. DAVIDSON SPRINGS, Ltd. Sept. 9, 1955 [Sept. 21, 1954], No. 27294/54. Class 120 (3). A skeleton cone or bobbin structure is composed of a helical spring 1 encased within a cage-like sheath formed by a length of wire 2 laced progressively, in substantially equal turns around adjoining coils of the spring from one end to permit limited radial spring movement, the lacing 2 being applied whilst the spring 1 is radially expanded under an externally applied torsional force, and acting by abutment between oppositely directed lacing turns 2b around individual spring coils, when the force is removed, to prevent the laced spring returning to the position which would, but for the lacings 2, be its neutral position of rest ; thus the whole of the permitted spring movement is available for further radial expansion of the spring. It is stated that when placed over a mandrel having an external diameter slightly oversize in relation to the minimum internal diameter of the laced structure, the latter has to be further radially expanded against considerable spring reaction, and the mandrel is gripped firmly by the structure.

Title: Improvements in or relating to reeling systems particularly applicable to the reeling of antenna wires in aircraft
IPC: H02G11/02
Filed: 1937-10-08
Abstract: 487,568. Winches. STANDARD TELEPHONES & CABLES, Ltd. Oct. 8, 1937, No. 37377. Convention. date, Dec. 30, 1936. [Class 78 (v)] In a reeling device for radio antennae carried by aircraft' feed-rolls 20, 21 are: provided which keep the length of antenna between them and the storage reel 100 always in tension, whether the reel be winding on or off, and to give a non- snarling wind the reel 100 is mounted angu-' larly on its driving shaft 13, its central' fibre web 7 being gripped between two tapered washers 1'6 so that the reel wobbles in turning. A friction drive is interposed between the reel and its shaft, consisting of leather washers 15 buttressed between a hub 8 pinned to the shaft 13 and a disc 10 slidable on flats on the shaft. An adjustable spring 12, non-rotatable with respect to the shaft and the disc 10, bears on the latter. The feed roll 21 is carried by a swinging shaft 34 spring-pressed to bring the roll 21 against the antenna lying in a groove in the rim of the roll 20, which is driven by the motor 18 through a gear-box 19 furnished with a ratchet-andpawl and pinion arrangement which rotates the roll 20 at different speeds in different directions. These speeds are such as to wind off the antenna from a full reel slightly faster than it would otherwise come off, and on to an empty reel slightly slower than the reel tends to take it, thus under every condition of direction and fullness of reel causing a slip to occur in the friction drive between reel and shaft 13. Means are also provided for paying-out, and taking-in, pre-determined lengths of antennae, cbnsisting of a switch-cam driven from the shaft of either the roll 20 or the roll 21, and operated by selective pressbuttons acting through relays to stop the motor 18 automatically at given points. Fig. 5 shows the apparatus mounted near the tail of an aeroplane, the antenna 23 passing through an insulating tube 50 to the rolls 20, 21 and the reel 100, and being tapped by springs 51 connected with a line 52. Wires 55 lead to the push-buttons located near the operator. A ball or fish 54 stretches out the antenna.

Patent GB-712704-A (GB)
Title: Improvements in or relating to process of preparing higher alcohols from aldehydes and the alcohols resulting therefrom
Filed: 1951-11-29
Abstract: Primary alcohols are made from normal saturated aldehydes of 2-4 C atoms per molecule by mixing them with Co and H2 in a mol. ratio of between 2 : 1 and 1 : 4 in the presence of a cobalt carbonyl and/or hydrocarbonyl catalyst at 120-200 DEG  C. and about 1000-10,000 p.s.i. for a period that establishes a mol. velocity as mols. of aldehyde per hour per gram atom of cobalt of not above 10 and so effecting an alcohol having at least twice as many C atoms per molecule as the starting aldehyde.  Preferably 0.01-0.2 gram atoms of cobalt per mol. of aldehyde is used.  Primarily acetaldehyde yields n-butanol, propionaldehyde hexanol and n-butyraldehyde 2-ethyl-1-hexanol The catalyst may be preformed or formed in situ before introduction of aldehyde or during the reaction from water soluble cobalt compounds such as the acetate or sulphate or insoluble compounds such as the oxide.  Oil dispersions and slurries of catalyst may be used.  A preformed catalyst is preferred.  The presence of a sulphur compound and a solvent will hasten the start of the reaction and if the catalyst is not preformed 0.1-5 per cent of an inorganic sulphur compound, e.g. ammonium or hydrogen sulphide is added.  The presence of water increases the tendency to form condensation products and the formation of higher alcohols.  Other specified solvents are non-olefinic hydrocarbons, e.g. paraffins and aromatics and ether.  Reaction is preferably effected for at least 2 hours, the products being cooled and allowed to separate into oil and aqueous layers.  Catalyst is removed from the oil layer by acid washing and the alcohols recovered.  When a mixture of aldehydes is used, e.g. acet- and propion-aldehyde products such as amyl alcohols may be obtained.  In examples, CO and H2 are reacted with (1) acetaldehyde in the presence of ethyl ether, cobalt oxide and ammonium sulphide (catalyst being preformed) to yield n-butanol and 2-methyl-1-pentanol with some ethanol; (2) paraldehyde in place of the acetaldehyde of (1) yields butanol and mixed hexanols and octanols; (3) propionaldehyde under similar conditions to those of (1) to yield 2-methyl-1-pentanol; (4) n-butyraldehyde in the presence of water, toluene, cabaltic oxide and ammonium sulphide to yield 2-ethyl-1-hexanol and butanol, the absence of water leading to an increase in the yield of butanol; and (5) n-butyraldehyde in the presence of aqueous cobalt acetate solution to yield 2-ethyl-1-hexanol, butanol and 2-ethyl-1-hexanol.

In the embodiments the mask is placed directly on an unexposed photo-resist and the resist exposed through it. In one set of Figures (Figs. 6A to 6T, not shown) a transistor of the type shown in Fig. 3 is built up by successive photo-resist, etching and diffusion techniques. In Fig. 3, an N-type silicon wafer 23 has boron diffused therein to give region 21 followed by phosphorus to give region 20 to which aluminium connections 25 and 26<SP>1</SP> are made. The electrode connections are made by depositing a film of A1 and etching away the unwanted portions using a separate mask or the mask used for forming the various semi-conductor regions. A silicon oxide film is left on the surface between the connections through part of the manufacturing process. The regions 15, 16, 17 and 18 are made during the process of manufacture due to successive movements of the mask but are not regions essential to the working of the device. In another set of Figures (Figs. 8A to 8K, not shown) a planar transistor is made.
