Title: Improvements in automatic braking apparatus for aircraft
IPC: B64C25/46
Filed: 1953-05-30
Abstract: 733.834. Anti-skid brake control system. DUNLOP RUBBER CO., Ltd., TREVASKIS, H. W., and MORTIMER, F. R. May 5, 1954 [May 30, 1953; Feb. 9, 1954], Nos. 15112/53 and 3731/54. Class 103 (1). An anti-skid device for control of fluid pressure brakes for aircraft of the kind described in Specification 676,708, is modified in that the fly-wheel element 7 is under constraint by a clock-type accelerating spring 16 in addition to the usual deceleration spring 13, the two springs acting together to hold the fly-wheel, when it is neither accelerating or decelerating with respect to the drum member 2, in a mid-position in which a spoke member 11 carrying the cam balls 27 lies mid-way between the ends 9 and 10 of a 120 degree slot in the part 5 which rotates with the drum member. Since the inlet valve to the brakes can only be opened when the fly-wheel spoke 11 is in midposition, it prevents an improper application of the brakes at the end of a long wheel bounce through which the fly-wheel may have lost speed and also corrects for too heavy an application at touch down due to the landing speed being considerably in excess of that necessary to operate the centrifugal releases 47. Specifications 683,490, 706,351 and 729,081 also are referred to.

Title: Improvements in the loading of telephone transmission lines
IPC: H04B3/26
Filed: 1926-06-17
Abstract: 277,427. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). June 17, 1926. Loading circuits to improve transmission.-If an entrance cable 10, Fig. 1, leading from an open-wire line 9 is uniformly loaded with coils 11, 12 .. so as to have a characteristic impedance equal to that of the line 9 thus avoiding any irregularity at the junction, the spacing of the coils 11, 12 - - does not correspond to the spacing of the loading coils 2 of a standard uniformly loaded toll cable 1 which may be routed through the same conduit. In order to avoid this inconvenience, entrance cables are, according to the invention, loaded so as to have the required characteristic frequency by means of equally-spaced alternate large and small inductance coils L1, L2, Fig. 6, which are so arranged that the large coils may be located in the existing manholes 5, 6 - , whilst the smaller coils, being of smaller size and relatively few in number can be readily housed at intermediate points. Alternatively, the coils may be of equal inductance value but spaced at alternately long and short intervals L, M as shown in Fig. 9, or unequal coils and unequal spacing may be combined. The loaded line may terminate at the mid-oipnt of a large coil L1, as shown in Fig. 6, or at the mid-point of a small coil L2, or by combination with a portion B B<1> of an equivalent uniformly-loaded line, Fig. 7, at any other position.

Filed: 1927-06-08
Abstract: 272,896. Geigy Akt.-Ges., J. R. June 18, 1926, [Convention date]. Grant of Patent opposed. Dye preparations. - Solid preparations in powder form, yielding dispersions with water suitable, for example, for dyeing acetate silk, are made by grinding insoluble or sparingly soluble organic dyestuffs or dyestuff intermediates (other than vat dyestuffs or lakes) with soap (i.e. salts of saturated or unsaturated fatty acids) or saponin at ordinary temperatures and in the absence of any other protective colloids. In an example, aminoazobenzene is ground with soap in solid form. Specifications 12955/05 and 219,349 are referred to. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the manufacture of solid preparations convertible into dispersions, from organic compounds in general, by grinding them, at ordinary or raised temperature, with dispersing agents, in the presence or absence of protective colloids. The process may be modified by separately grinding the ingredients, mixing them, and exposing the mixture under pressure to a temperature not harmful to the ingredients, or the ingredients may be suspended in water and the suspension dried and then ground. The dispersing agents mentioned are soaps, including neutral or acid salts of saturated, unsaturated or sulphonated fatty acids 'and salts of naphthenic acid and of acids produced by the oxidation of paraffin or brown coal, resin soaps, saponins, lignine and lignine-sulphonic acids and their salts, and the condensation products of formaldehyde with naphthalene sulphonic acids or with phenols or their sulphonic acids or their salts. Suitable protective colloids are starch, dextrin, British gum or other starch products, glue, gelatine, gum arabic and other gums. The dispersing agents and protective colloids can be used singly or in admixture. In additional examples, (1) the indophenol from p-aminodimethylaniline and alpha-naphthol is stirred with a solution of soap, turkey red oil and dextrin, dried and powdered, (2) 1 : 4-diaminoanthraquinone is ground with a naphthalene sulphonic acid and formaldehyde condensation product and British gum, (3) dianisidine is ground with saponin or sodium lignine-sulphonate and starch. and (4) finely divided phenol is mixed with pulverized soap; the product when mixed with a little water yields a solution which can be diluted as desired without separation of the phases. This subjectmatter does not appear in the Specification as accepted.

IPC: C07C51/25
Filed: 1949-03-25
Abstract: The invention comprises a -neopentyl acrylic acid which is made by subjecting a -neopentyl acrolein to mild oxidation.  The oxidation may be effected in the liquid phase with molecular oxygen at below 100 DEG  C. or with an oxidizing agent such as silver oxide.  The methyl and p-bromophenacyl esters are described and the acid and esters may be hydrogenated to the corresponding trimethyl pentanoic derivatives.  In an example a -neopentyl acrolein is treated with oxygen at 15 DEG  C. to yield the required acid and the acid hydrogenated using Adam's platinum catalyst to give 2,4,4-trimethyl pentanoic acid.

An earth conductor 24 from a piece of equipment is brazed to the inner end of the strip 22 and a metal cylinder 26 is brazed to the outer end 28 of the strip 22. The end of a rod 32 is engaged in the cylinder 26 and the rod is driven into the soil, Fig. 10. The strip 22 is thus uncoiled and when the cylinder 26 is at the desired depth the rod 32 may be removed and an aqueous solution of an earth treating agent may be poured into the resulting hole to reduce the resistance between the strip 22 and the soil. The rod 32 may be made of one piece or may be made of sections 32a, 32b, 32c as shown which are screwed together, a head 34 being screwed on to the uppermost section. Instead of the strip 22 the electrode may be formed of a coiled wire (22a, Fig. 4, not shown). Two similar electrodes may be attached to one metal cylinder (Fig. 5, not shown) for driving into the soil or four electrodes may be attached to one cylinder (Figs. 7, 8, not shown).
