Title: Improvements in or relating to ordnance
IPC: F41A19/06
Filed: 1942-04-13
Abstract: 578,629. Automatic ordnance. MOLINS, D. W., HARVEY, V. P., MASON, J. A., POWELL, G. F. W., and MOLINS MACHINE CO., Ltd. April 13, 1942, No. 18638 /43. Divided out of 578,621. [Class 92 (ii)] Relates to firing mechanism for automatic and semi-automatic guns of the kind in which the transversely-sliding breech block is automatically opened on run-out and closed by the insertion of a round, the firing-pin being cocked by a lever during opening of the breech and the cocking-lever returning clear of the pin when the breech closes. According to the invention, a pressure device is operatively associated with the cocking-lever so as to operate the firing button only after the cocking-lever has returned. The invention is shown applied to the breech of a gun having the automatic fuze setting, loading and firing cycle described in Specification 578,621. Fig. 2 illustrates, the rear of the wedge breech block 310, the T- headed cocking-lever 330, and the hand firing- lever 313 which operates the firing-button 333 through plunger 305 and lever 332. The present invention provides, between the cocking lever 330 and a spring-pressed lever 321 that automatically fires the gun through cams 326, 327, a spring-pressed control-lever 315. This lever by engaging the breech block and a surface 324 on lever 321 only premits firing movement of the lever 321 when the breech is closed and the cocking-lever has returned. The spring pressure device 334 acting on the lever 321 is shown in Fig. 3, and a handle 338, when turned from the position A to position H, puts the lever 321 out of action to permit of hand-firing by lever 313. In a modification, firing is automatically effected through a spring plunger device by the return of the loading tray clear of the recoiling parts.

Title: Phenol-formaldehyde-acetone resin
Inventor: CAMBRON EMILE ADRIEN
IPC: C08G8/26
Filed: 1960-05-26
Abstract: A thermosetting laminating resin is prepared by reacting acetone and formaldehyde in alkaline solution to form a monomeric monomethyl derivative of acetone, reacting this derivative under alkaline conditions with phenol or cresol or a mixture of phenol and cresol, and then reacting with addition formaldehyde also under alkaline conditions.  In the example, sodium carbonate is used to catalyse each stage of the reaction, and the final product is dissolved in methanol to give a laminating varnish. Specification 948,776 is referred to.

Filed: 1962-05-15
Abstract: 979,517. Forging; reworking worn rails. GES FUR FERTIGUNGSTECHNIK UND MASHINENBAU G.m.b.H. May 15, 1963 [Aug. 24, 1962], No. 19196/63. Headings B3H and B3V. [Also in Division G3] A forging machine, particularly for re-working worn rails 3, Fig. 2, has its hammer 2 driven by an electric motor 5, Fig. 1, the input power of which is used to control, within preset limits, the effective stroke position relative to the workpiece. The hammer 2 is actuated by an eccentric on shaft 4 and its stroke position may be controlled; preferably however the position of an anvil 6 for the workpiece 3 is adjusted in height automatically by wedges 11  operated by threaded portions 10 of a spindle 9 driven by a reversible motor 7. The spindle 9 simultaneously adjusts through linkage 18-21, the height of two pairs of oblique rollers 16 which support the rail workpiece as it is fed beneath the hammer 2. Anvil 6 is also adjusted horizontally by a wedge 12 operated manually through gearing 14, 15. For adjusting the workpiece height in dependence upon the power input to motor 5, one of its supply lines T, Fig. 5, includes a transducer U whose secondary energizes relays D 1 , D 2  preset by rheostats R 2 , R 3  to upper and lower control limits. These relays when energized, control directly or through further relays C 1 , C 2  solenoid switches S 1 , S 2  in the circuit of motor 7 whereby the latter is driven to lower the workpiece when the input power increases above the limit set by R 3  and to raise the workpiece when the power falls below the limit set by R 2 . Rheostat R 1  is used to preset the mean control voltage or a transducer with a variable number of turns may be used. Alternatively the motor 7 may be an hydraulic motor controlled by solenoid-operated valves.

[Also in Divisions B1 and B2] In an embodiment especially for drying, of apparatus for contacting fluids and particulate solids, the solid is fed by a conveyer 63 to a pre-drier 62 where it descends on trays 64 while being heated or dried by exhaust air from the chain apparatus. It then falls into a hopper 65 supplying a screw conveyer by which it is delivered to the upper surface of a rotating disc 12. Hot air delivered below the disc from the pipe 59 carries the powder up the annular space 25 at the top of which it separates out by cyclone action and falls through outlets 37, while the air passes down between the cylinders 16, 17 and up the track 17 to the predrier. The separated powder falls to an annular bed 55 where it is maintained in a fluidized state by air entering at 57; the final powder product is removed from the bed 55 by a downtake 58 while the fluidizing air passes through pipe 59 to the main apparatus. Heating coils 57, 60, 61 are provided. The fluidization chamber 25 may be subjected to an electric field or ionizing radiation.

Title: The manufacture of azodyestuffs
IPC: C09B29/20
Filed: 1938-07-06
Abstract: 516,773. Dyeing. I.G. FARBENINDUSTRIE AKT.-GES. July 6, 1938, No. 20055. Convention date, July 6, 1937. [Classes 2 (iii) and 15 (ii)] Water-insoluble azo dyestuffs are manufactured on the fibre, e.g., on textiles of natural or regenerated cellulose, or on animal fibres, by coupling diazotized aniline which contains in 3- or 4-position in a ketonic linkage the residue of an organic carboxylic acid, e.g., of the aliphatic, aromatic, hydroaromatic or araliphatic series, and which is further substituted twice by alkyl and/or alkoxy groups, with an arylamide of an aromatic o-hydroxycarboxylic acid, the components being free from water-solubilizing groups. The formation of the dyestuffs may be carried out by the usual ice colour process, or by using the dizao compounds in stabilized form, e.g., as nitrosamines or diazoamino compounds. In examples: (1) cotton ware piece goods are impregnated with 2-3-hydroxynaphthoic acid 2-methoxy-4-chloranilide and a bluish-bordeaux dyeing is developed with diazotized 2:4-dimethoxy-5-aminoacetophenone (2) cotton yarn is impregnated with. 2:3- hydroxynaphthoic acid alpha-naphthylamide and a bordeaux dyeing is developed with diazotized 3-amino-2:5-dimethoxybenzophenone. In a table of further combinations the following additional components are specified: dizao components : 2:4-dimethoxy-5-aminobenzophenone and -propiophenone, 2:4-diethoxy-5- aminoacetophenone, 3-amino-2:5-dimethoxyacetophenone and 2-methoxy-4-amino-5-methyl acetophenone ; coupling components : the 2- and 3-methyl-4-methoxyanilides, 2-methoxy-5- chloranilide, 2:4-dimethoxy-5-chloranilide, 2:5- dimethoxy-4-chloranilide,- o-anisidide, o- and p-toluidides, 2:5-dimethoxyanilide, o-phenetidide, 4-chloranilide and 2-methyl-4-chloranilide of 2:3-hydroxynaphthoic acid, 1-(1<1>-2<1>-benzocarbazole - 5 - <11> - hydrdxy- 4"-carboylamino)-4- methoxybenzene and 1-methyl-2-(1<1>-2<1>-benzocarbazole - 5<11> - hydroxy - 4<11> - carboylamino) -5- methoxybenzene. Specifications 17,279/13 and 279,146, [both in Class 15 (ii)], are referred to. Aminoketones of the type defined above are obtainable by nitrating the correspondingly substituted ketones and reducing the nitro compounds, or by introducing the carboxylic acid residue into suitably substituted anilines by the Friedel-Craft reaction. Thus 3-amino- 2:5-dimethoxybenzophenone is obtainable by nitration and reduction from 2:5-dimethoxybenzophenone. The Specification as open to inspection under. Sect. 91 comprises also the manufacture of the dyestuffs in substance. The products are pigment dyestuffs. This subject-matter does not appear in the Specification as accepted.
