Title: Improvements in or relating to stud welding
IPC: B23K9/20
Filed: 1965-08-13
Abstract: 1,121,105. Welding by pressure. OMARK INDUSTRIES Inc. 13 Aug., 1965 [21 Aug., 1964; 24 Aug., 1964], No. 34800/65. Heading B3R. In arc stud welding with a stud having a tip portion of smaller cross sectional area than the shank of the stud the stud holder falls freely under gravity to contact the stud with the work and the tip portion is vaporized and an arc is produced between the end of the stud and the work. A shaft 14, Fig. 1, carrying at one end a stud holder 16 has an enlarged head 18 functioning as a piston in a cylinder 10 and extending out of the cylinder. The lower end of the cylinder is closed by a plug 26 and an aperture 30 in the cylinder wall is connected to a source of compressed air through a solenoid operated valve 46, the valve normally permitting air to raise the stud holder clear of the work. Lead shot 46 is provided in a cavity 66 in the enlarged head 18, being packed loosely to absorb reactive shock forces, and a member 70 on the head 18 slidably engages a guide 74. The shaft 14 is connected to one side of a capacitance 80 via a normally open switch 88 and the work is connected to the other side. The welding stud has a small projecting tip 96. In operation the air in the cylinder 10 is quickly exhausted through the valve 46 and the shaft 14 and stud holder fall freely, the switch 88 being closed so that on contact with the work the stud tip is vaporized to create an arc or the arc may be produced first. In a modification a shaft carries a collapsible stud holder at one end and a number of weights of iron, lead &c. at the other end and is slidable in a housing. The shaft is raised by engagement of a piston-rod with a weight support at the upper end of a shaft, the piston of the rod being arranged in a cylinder in the housing. A guide rod secured to the weight support engages a cavity in the housing and the rod forms a cam surface for a cam operated switch for connecting a capacitor between the stud and work. The housing is arranged for vertical adjustment by a hand wheel. In operation with the stud raised by the piston, the piston is caused to be urged rapidly downwardly by air pressure and the shaft falls feely by gravity, an arc which vaporizes a conical extension on the stud forming between the conical extension and the work before the stud hits the work. When the stud hits the work the stud is released by the collapsible stud holder to prevent rebound. The work is clamped by a pressure fluid ram during welding.

Abstract: 869,378. Photo-electric apparatus. PARKINSON COWAN Ltd. Oct. 27, 1959 [Oct. 30, 1958], No. 34859/58. Class 40(3) A system for transmitting the reading of an instrument to a remote point comprises an element arranged to be rotated synchronously with a receiver and carrying a source of light and a photo-cell operating in conjunction with two devices for reflecting or varying the intensity of light received by the cell from the light source, one of the said devices being mounted at a fixed point in relation to the instrument scale, and the other being mounted to move with the pointer or equivalent member of the instrument. The dial of the instrument 1 is formed with a black disc 2 provided with a mirror 3 and the pointer 5 carries a mirror 4. A motor 15 mounted on a plate secured by studs 7 to a ring 8 adjacent an opening in the instrument face drives a disc 10 carrying a photo-cell 12 and an adjacent lamp 13, the arrangement being that a cam 19 on the shaft of the motor closes a micro-switch 18 effecting the energization of a relay, when the beam from the source 13 is reflected by the fixed mirror 3 to the photo-cell 12. When the light beam is reflected from the mirror 4 carried by the pointer 5 on to the cell 12, a pulse is passed via slip rings 11 on the disc 10 to energize the electromagnetic relay which is arranged to switch on and switch off a transmitting circuit. At the receiver, a relay correspondingly operated and de-energized operates a clutch to connect and disconnect a pointer to a synchronous motor. In an alternative arrangement, the disc 2 may be a gloss white, whilst the fixed member 3 together with the pointer 5 have a matt black surface.

Patent GB-1017870-A (GB)
Title: New anthraquinone dyestuffs and process for their manufacture
IPC: C09B1/58
Filed: 1964-08-26
Abstract: The invention comprises anthraquinone dyestuffs of the formula <FORM:1017870/C4-C5/1> in which A is NH2 or nitro group, X represents an arylmercapto group consisting of not more than two condensed carbocyclic rings, which may be substituted by halogen atoms, alkyl groups or phenyl groups, and Y represents a hydrogen atom or a halogen atom or a cyano group or an aliphatic, aromatic or a heterocyclic acylamino group.  The dyestuffs may be made by condensing an appropriate 1-amino or nitro-anthraquinone 2-carboxylic acid halide with an arylmercapto-substituted 1-amino-anthraquinone. Alternatively the corresponding anthraquinone carboxylic acid in admixture with the aminoanthraquinone may be heated with thionyl chloride.  If the nitro-substituted dyestuff is formed it may be converted to the amino-substituted dyestuff by reduction with hydrosulphate or reaction with ammonia.  The 1-chloroanthraquinone-2-carboxylic acid halide may also be condensed with the aminoanthraquinone, the chlorine being converted to amino by reaction with ammonia or arylsuphonamides. The arylmercapto group may be introduced after the condensation by reacting a dyestuff of the above formula where A is amino and X is a substituent that can be replaced by an aryl mercapto, e.g. nitro or a halogen atom, with an aryl mercaptan. The dyestuffs in which Y in the formula is an aliphatic, aromatic or heterocyclic amino group can also be prepared by condensing a compound of the above formula wherein A and Y are both amino groups with an aliphatic, aromatic or heterocyclic carboxylic acid halide.

[Also in Group XIII] In a system for maintaining a constant temperature within an enclosure on an aircraft, in which a servomotor controls a mixer valve admitting a mixture of hot and cold air to the enclosure, the two air streams are derived from a vortex tube supplied with ram air from an inlet in the leading edge of the wing. The ram air entering at 13 is separated by the vortex tube 15 into a hot (peripheral) component collected by duct 19 and a cold (central) component collected by duct 17. The two ducts supply the enclosure 45 via the mixer valve 27 actuated by a reversible two-phase motor 51, which also actuates spill valves 55 which discharge the surplus air. The enclosure 45 is vented at 43. The motor 51 is controlled by an undisclosed temperature-sensitive device 47 and amplifier 49. Reference has been directed by the Comptroller to Specifccation 698,407, [Group XIII].
