Title: Process for printing and padding textiles and preparations therefor
IPC: D06P1/12
Filed: 1957-10-18
Abstract: Textile materials are coloured with a colour capable of being developed under neutral or acid conditions by the use of a padding or printing colour which contains as coupling component a 4-arylazo-1-amino-7-oxynaphthalene free from groups imparting solubility in water and a stabilized diazo-compound of the formula:- <FORM:0863216/IV(c)/1> in which R represents an at most bicyclic aryl residue free from groups imparting solubility in water and X represents a hydrocarbon radical which may contain groups imparting solubility in water.  Preferred diazo compounds are those in which X represents an alkyl group, which may have a branched chain, and R represents a benzene residue which contains at least one substituent not imparting solubility in water.  Preferred coupling components are 4-arylazo-1-amino-7-oxynaphthalenes of the formula:- <FORM:0863216/IV(c)/2> in which R1 represents an at most bicyclic aryl residue, more especially a naphthalene residue which may be substituted, or preferably a benzene residue which contains at least one substituent not imparting solubility in water.  The coloured material may be treated with bichromate after the printing or padding operation, preferably in an acetic acid bath before the coloured material is dried and steamed or subjected to dry heat treatment at temperatures above 100 DEG C.  For printing, a printing paste is preferably used, and for padding, a solution obtained by replacing by water 70-100% of the thickening agent used in the printing paste. Examples of the colouring of cotton fabrics are given, and many dyestuff components are specified.  Specifications 785,613 and 829,570 are referred to.

Title: Process for the preparation of lubricating oils with improved viscosity characteristics
Filed: 1952-12-24
Abstract: A process for the preparation of lubricating oils comprises subjecting a mineral lubricating oil fraction to a pretreatment with a liquid alkylation catalyst to remove highly reactive aromatic compounds and subsequently alkylating the aromatic compounds remaining in the lubricating oil fraction in the presence of a solid alkylation catalyst by means of an alkene or alkyl monohalide.  The liquid alkylation catalyst may be liquid hydrofluoric acid, used in quantities between 10 and 100 per cent. by volume based on the oil, and preferably at temperatures of 0 DEG  to 20 DEG C.; sulphuric acid, in quantity between 5 and 100 per cent. by volume, and temperature between -20 DEG C. and 100 DEG C.; or a Gustavson complex (obtained by reacting aluminium chloride with an aromatic hydrocarbon oil), in quantity between 5 and 40 per cent. by weight, and temperature between -20 DEG C. and 100 DEG C.  The solid alkylation catalyst may be aluminium chloride or bromide, zinc chloride, ferrous chloride, stannic chloride or phosphorus pentoxide.  The alkene, which may be pure or a mixture of alkenes, has straight chains of 5 to 18, preferably 8 to 18, carbon atoms. The corresponding alkyl monohalides may also be used.  Before the pretreatment with the liquid alkylation catalyst the oil may be dewaxed such as by diluting with a solvent, e.g. methylethylketone or methylisobutylketone, and cooling to crystallize the wax.  The oil may also be treated with sulphuric acid before dewaxing to remove asphaltenes if any are present.

Patent GB-364237-A (GB)
Title: Improvements relating to the control of distant mechanisms by wireless communication
IPC: H04B1/04
Filed: 1930-11-04
Abstract: 364,237. Wireless control of distant apparatus. CHANCE BROS. & CO., Ltd., and SPAINK, J. H., ABBINK-, Lighthouse Works, West Smethwick, Staffordshire. Nov. 4, 1930, No. 33118. [Class 40 (v).] A wirelessly operated relay for controlling distant mechanism is associated with a thermostatic switch so that the signal must be sustained for a predetermined time before the switch can start the mechanism. The invention is described with reference to a starting motor for the engine operating a fog signal at a remote position, at which circuits 1 .. 9 are shunted across a storage battery s. The train of wireless waves for starting up the fogsignal closes contact x, circuit 2, energizing relay r and closing contact r<1> in circuit 3 with heater h. After a predetermined time the heater moves the switch arm h<1>, circuit 4, from the full to the dotted line position, thus causing the self-locking relay b to close circuit 5 through relay a, contacts c<1> already being closed by relay c, circuit 8. Relay a operates contacts a<1>, a<2>, circuit 1, to start the motor m<1> for starting the engine, and also contacts a3 in circuit 9. A heavy current passes through the field m<2> and armature ml windings, but current through relay winding v<1> prevents actuation of the contacts controlled by v. After the engine has started, the motor is driven thereby and the back e.m.f. generated reduces the current through v<1> and allows v to close v<2>, circuit 7, whereupon relay f opens f<2>, circuit 5, and puts a out of action and opens a<1> and a<2>. Also f closes f bringing g into action to move arm g<1>, circuit 8, after a predetermined delay from the full to the dotted line position to energize d and close contacts d<1>, circuit 5, in readiness for stopping the engine. Before g<1> has changed over r has released r<1> and h<1> has returned to normal, short-circuiting b and causing b<2> to be re-opened. To stop the engine another train of wave repeats the operations, but c, circuit 8, is now out of action and current flows through d<1>, already closed by d, to operate relay e and the contacts el for disabling the magneto i. The closure of a<3> energizes magnet k to open the engine fuel valve and y to close a release valve in the compressed air receiver, if used, these magnets being energized through contacts f 3 as long as the engine is running. The magnet o, circuit 5, partially closes the engine throttle as long as relay b is energized.

Title: Improvements in or relating to fuses for grenades and other projectiles
IPC: F42C7/12
Filed: 1935-12-02
Abstract: 464,935. Projectile fuzes. CRAVEN, P. A. Dec. 2, 1935, No. 33316. [Class 9 (i)] A grenade or other projectile is provided with a coil spring 1 surrounding the striker 4, one end 3 of the spring being attached near the base of the cylindrical tube 2 whilst its other end is secured at 3<1> to the striker. The striker is adapted to be partially withdrawn from the cylinder 2, e.g. by means of a lever handle, the spring 1 being thereby extended and the striker may be held in this withdrawn position by means of a release or shearing pin. Withdrawal or shearing of this pin causes the striker to be driven forward by the spring 1 so as to cause its end 4 to strike the detonating cap 7, the subsequent rebound of the coils of the spring to their normal position freeing the striker from the cap 7. Thus positioned, reapproachment of the striker and detonating cap is practically impossible until after the spring has been again extended and released as above described.
