Patent GB-590542-A (GB)
Abstract: 590,542. Gas burners. BARKER, W., and MASKERY, C. June 26, 1945, No. 16237. [Class 75 (i)] A gas burner of the Bunsen type has a flanged metal base 1A of channel section which admits air to the burner, one side of the channel closing one end of the jet tube 1B. Gas is supplied to the jet 1C through the tube 1B, while the air is supplied through the channel, the mixing tube, which consists of a chimney 2A with a flange 2C being longitudinally adjustable with respect to the jet 1C by sliding in a friction sleeve 1D which is fastened in a machined hole in the base. The lower end 2B of the chimney 2A may be draped to fit over the pipe 1B to shut off the air altogether, and rotation of the chimney 2A when the end 2B is resting on the tube lifts the chimney and permits of a fine control. A shield 2C may be attached to the chimney 2A to facilitate its adjustment when hot, and to protect the sleeve 1D from corrosion.

Title: Methods of duplicating magnetic tape recordings
IPC: G11B15/467
Filed: 1973-12-20
Abstract: 1454555 Duplicating magnetic tapes MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 Dec 1973 [30 Dec 1972] 59247/73 Heading G5R In a method of duplicating video magnetic tape recordings in a contact-type video tape printer, wherein a master tape and a copy tape are brought into contact with one another, playback tracking servo control pulses are recorded on to the master tape prior to the printing step, the gradient of the leading edge of each such pulse being substantially different from that of its trailing edge. The control pulses may have a trapezoidal or sawtooth shape. The magnetic coatings of a master tape 3 from a reel 1 and a slave tape 4 from a reel 2 are brought into intimate contact at a capstan 5 and wound together at high speed on to a reel 7, the tapes are thereafter rewound on to reels 1, 2 at slow speed whilst being subjected to the action of a magnetic flux or heat generator 8. The resultant control signals on tape 4 have less overshoot and print through noise pulses than tapes duplicated from masters having the usual rectangular control signals thereon. The control signals are recorded on the master tape by passing the vertical sync. pulses of a composite video signal from a sync. separator into a bi-stable circuit, the output of which triggers a monostable circuit which in turn triggers a sawtooth or trapezoidal wave generator feeding a record head, Figs. 6, 7 (not shown).

Patent GB-615163-A (GB)
Abstract: 615,163. Burners for gaseous fuel. SCHAFER, J. July 30, 1946, No. 22701. Convention date, Sept. 3, 1945. [Classes 75 (i) and 75 (iii)] A gas burner comprises one or more mixing units each comprising a gas nozzle discharging into a conically converging bore, the mixer body being formed with elongated air inlet passages inclined to and converging on the axis of the bore on to which they open at the rear end with the air discharge openings substantially in contact. In the burner shown the gas nozzle 1 discharges into a conical mixing chamber 3 into which inwardly inclined air passages 4 open at the rear and with their discharge openings in contact and the mixture leaving the chamber 3 is discharged through a nozzle 5 into a second conical mixing chamber 7 formed with similar elongated inwardly inclined air inlet passages 8 also having their discharge openings in contact. The discharge nozzle of the burner is formed by a screw cap 9 fitted with a central tube 10 formed with peripheral grooves 11, the outlet end of the cap being formed with a converging wall 13 to direct the mixture flowing along the grooves 11 towards the core of the gas stream flowing through the tube 10 and thereby shaping and stiffening the flame. The burner is stated to operate with gas pressures of 8 grammes per square centimetre upwards. The air flow may be regulated by an adjustable collar 15 fitted with an annular spring 16 to retain it in position when adjusted. The burner may be ignited by presenting a flame at the ports 8 and then closing the openings by the collar 15 to cause the flame to jump' to the opening 14. The main part of the burner may be of aluminium, the cap 9 and tube 10 being of brass. Specification 592,816 is referred to.

Abstract: 1,260,878. Purifying aluminium. DOW CHEMICAL CO. Dec. 18, 1969, No. 61767/69. Heading C7D. [Also in Division C1 A process for the purification of aluminium by removing silicon from an aluminium alloy comprises reacting the alloy with sulphur or a sulphide at a temperature sufficient to produce and evaporate silicon subsulphide (SiS), and cooling the residual alloy. The sulphide may be Al 2 S 3 , H 2 S or SiS 2 . The silicon subsulphide vapours may be condensed to produce silicon (See also Division C1) and SiS 2  the latter being subsequently used to react with further aluminium alloy. A storchrometric quantity of the sulphide or sulphur is preferably used though where Al 2 S 3  is used excess Al 2 S 3  serves as a flux. The low silicon alloy may be further treated with Al 2 S 3  at a temperature sufficient to form and evaporate aluminium subsulphide (Al 2 S), the vapour being condensed to yield pure aluminium and Al 2 S 3  the latter being returned for further reaction with the low silicon alloy. Oxidation may be prevented by the use of an inert atmosphere e.g. argon.

Filed: 1978-11-03
Abstract: A printing unit for an offset rotary printing machine, having a plate cylinder 5, a blanket cylinder 2, an inking unit 8 for supplying ink to the plate cylinder and a dampening unit 15. In order to remove dirt and fibre particles picked up by the blanket cylinder, the dampening unit is arranged for applying dampening liquid onto the blanket cylinder during printing. Preferably, the dampening unit is arranged at a region of the blanket cylinder between the contact regions of the latter with the impression and plate cylinders. In use the dirt particles are removed from the blanket cylinder by the dampening unit before they can be carried round by the blanket cylinder to the plate cylinder where they would get mixed in with the ink. An application roller of the dampening unit may be driven at a different peripheral speed to that of the blanket cylinder. The damping liquid may be supplied in a recirculatory system and be passed through a filter during recirculation. <IMAGE>
