Filed: 1947-11-14
Abstract: 646,944. Cylinder locks. BRYCE, E. J. Nov. 14, 1947, No. 30319. [Class 44] A lock for a door 17, Fig. 2, or the like comprises a cylindrical member 2 disposed with its axis of rotation parallel with the plane of the door and with a part of the cvlindrical surface accessible on at least one side of the door, the cylindrical member being furnished with a radial keyhole and also with a lug 6 coacting with a notch 18 in the latch 8. When a key 1 is inserted in the keyhole and the cylinder thereby rotated the lug 6 moves into a shallower part of the notch 18 and allows the latch 8 to be retracted against the action of a spring 7 by means of an arm, not shown, engaging a slot 9 in the latch, the arm being formed rigid with a handle-operated spindle. On further rotation of the cylinder 2 by the key 1 the lug 6 re-enters the deeper portion of notch 18 and retains the latch in its retracted position. The key 1 is provided with notches 3, 3<1>, Fig, 6, for cooperating with pivoted levers 19, 20, and is formed with a rib 13. The levers 19, 20 are pivoted to plungers 4, 4<1> respectively which can engage notches 16 in the casing 5 enclosing the barrel 2. In the locked condition of the barrel the plunger 4 alone engages a notch 16 but on inserting the key 1 the lever 19 withdraws the plunger 4<1> until the key is fully inserted, when the notch 3<1> allows the plunger 4<1> once more to be retracted by its spring. If a keyhole 14, Fig. 8, is provided on each side of the barrel then a seesaw 10 may be provided to block the keyhole which is not in use. Also a pivoted lever 12 acted upon by compression springs may engage and steady the key 1, a longer key being used from one side than from the other.

Patent GB-494625-A (GB)
Title: New basic condensation products
IPC: C08G73/02
Filed: 1937-11-09
Abstract: The hydroxylated polyamines obtainable by treating a glycerol dihalogenhydrin or epihalogenhydrin with ammonia or an amine are treated to replace all or some of the hydroxyl groups by halogen atoms, and the halogenated polyamines so obtained are condensed with ammonia or a primary, secondary or tertiary aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic amine.  The products yield lakes with substantive or acid dyestuffs, and may be used for after-treating textile fibres dyed with such dyestuffs, whereby the fastness of the dyeings is improved.  The starting materials may be prepared by reacting a glycerol dihalogenhydrin or epihalogenhydrin with ammonia or an aliphatic, aromatic or heterocyclic amine.  The conversion of the hydroxylated polyamines so obtained into halogenated polyamines, which may still contain hydroxyl groups, may be effected with hydrogen chloride under pressure, or by the action of thionyl chloride at 5-100 DEG  C., or by means of phosphorus pentachloride or sulphuryl chloride.  The reaction of the halogenated polyamines with ammonia or amines may be effected at 60-120 DEG  C. in the presence of a solvent and an acid-binding agent.  In the examples: (1) a reaction product of glycerol a , g -dichlorhydrin and monoethanolamine is treated with thionyl chloride, and the product is treated with pyridine; a solution of the final product may be used for treating cotton or viscose rayon dyed with chloramine pure blue A; (2) a halogenated polyamine obtained as in example 1 is treated with p-phenylenediamine or (example 3) with aniline; (4) a reaction product of glycerol a , g -dichlorhydrin and ammonia is treated with thionyl chloride, and the product is treated with ammonia or (example 5) with pyridine; (6) as in examples 1-3, but with different proportions of the reagents; o-phenylenediamine may also be used in the final condensation; (7) a reaction product of glycerol a , g -dichlorhydrin and diethanolamine is treated with thionyl chloride, and the product is treated with pyridine.  The Specification as open to inspection under Sect. 91 covers the use as starting materials of polyamines in general containing one or more alcoholic hydroxy groups, and refers to the use of products obtained by the reaction of ethylene oxide with ammonia or its organic derivatives, or by the reaction of ethylene bromide or chloride with primary or secondary hydroxyalkylamines such as mono- or di-ethanolamine.  The conversion of the hydroxypolyamines into bromopolyamines, which may still contain hydroxyl groups, is mentioned.  This subject-matter does not appear in the Specification as accepted.

Abstract: 874,126. Cathode-ray tube circuits. BUSH & RANK CINTEL Ltd. Sept. 24, 1959 [Sept. 26, 1958], No. 30804/58. Class 40(7) A circuit for preventing burning of a cathoderay tube screen due to the occurrence of beam current on switching off the equipment comprises at least one diode, shunted by a resistor, connected between a source of potential and the cathode, and a capacitor returning the cathode to a source of constant potential, it being so arranged that the time constant of this circuitry greatly exceeds that of the grid circuitry. The supply 6 feeds both the anode voltage source 2 and the time-base unit 7. The cathode of the tube has associated with it circuitry as shown or, in order that the high insulation capacitor 11 may be replaced by an electrolytic capacitor, two diodes in series are substituted for diode 10 and their common junction taken to earth through the electrolytic capacitor. The time constant of the grid circuit being much less than that of the cathode circuit, at switch-off the grid falls rapidly to earth potential whereas the cathode potential falls only slowly so that the electron beam is immediately cut off.

Title: Improvements in or relating to the manufacture of coloured articles from dispersions of rubber or the like
IPC: D06P3/79
Filed: 1929-10-11
Abstract: 338,303. Dunlop Rubber Co., Ltd., Twiss, D. F., Murphy, E. A., and James, R. G. Oct. 11, 1929. Colouring rubber articles.-Rubber etc. articles obtained from aqueous dispersions by dipping, spreading, painting, extruding, spraying, electrophoresis, impregnating, or moulding are coloured by chemical reactions locally or generally over their surfaces subsequent to the formation of the article either by incorporating one or more of the reacting substances with the aqueous dispersion before the formation of the article, and then treating the formed article with a second reagent, or alternatively the formed but not dried article may be brought into contact with chemical reagents, which upon further treatment with other reagents will form the desired colour. In addition to the usual compounding ingredients, aqueous dispersions of synthetic or mineral rubbers or rubber substitutes such as factice, or cellulose esters or casein may be added to the aqueous dispersion of rubber. Example. A wet shaped deposit is produced from latex containing a substance such as #-naphthol which can react with a diazo solution to produce a dyestuff preferably insoluble in water. The formed but not dried article is immersed in a solution of diazotized aniline, p-nitraniline or primuline to produce a red azo dye. If desired the application of the diazo solution can be local with consequent local development of colour. In other examples (1) the formed article is dipped in a solution of indigo white, and becomes blue by oxidation; (2) an article which has been coagulated or set by an aluminium or other salt is dipped in a hot solution of alizarin, to form a lake; (3) an article which has been set by an acid coagulant is dipped in an alkaline sulphide solution of a sulphur dye to precipitate the dye. Specifications 290,313 and 303,544 are referred to.

Title: Improvements in or relating to microphones
Inventor: CRAGG WILLIAM DONALD
IPC: H04R1/22
Filed: 1959-09-11
Abstract: 915,811. Microphones. STANDARD TELEPHONES & CABLES Ltd. Sept. 11, 1959, No. 31044/59. Class 40 (4). A pressure gradient directional microphone has the rear portion of its diaphragm D connected by tubes L1 and L4 to a cavity C3 having access to the external air via shallow holes R3 and a tube L8 and to a closed chamber C2 via a further tube L2. Tubes L4 are held in gaskets R4 of acoustic resistance material such as porous metal. The tube L2 contains acoustic resistance material such as lambs' wool. The shallow holes R3 are also covered with acoustic resistance material such as silk. For producing the phase change necessary to produce a cardiod polar diagram the rear of the diaphragm is fed, in the case of signals below 300 c./sec. via a low-pass system comprising the tube L8; and in the case of signals above 300 c./sec. via the resistance capacitance system R3, C3. The directional effect is arranged to fall off between 3000 c./sec. and 6000 c./sec. after which the " obstacle " effect is relied upon to produce the directional characteristics. The L2, C2 system increases the low frequency response. The high frequency response of the microphone may be reduced by the provision of an annular ring attached to the diaphragm. The response may be boosted in therange 3000-4000 c./sec. by the provision of a tube in a position similar to that of L4, said tube being closed at the end remote from the diaphragm and containing acoustic resistance material at its other end. The chamber C3 may contain thin spiralled layers of acoustic resistance material.
