Title: Improvements relating to etching processes
Inventor: HOLMAN HERBERT EDWARD
IPC: C03C15/00
Filed: 1950-02-01
Abstract: 723,303. Etching. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 1, 1951 [Feb. 1, 1950], No. 2557/50. Class 100 (2). [Also in Group XL (a)] A method of etching includes the step of forming a resist on a surface to be etched by evaporating a non-metallic material and condensing the vapour thereof on said surface. The resulting resist coating is sufficiently non- porous even when thin. The resist material may be polythene, polystyrene, bitumen, colophony resin, or paraffin wax. A coating of metal, e.g. silver, platinum, gold or copper may be applied to the surface of a glass plate by condensation in a vacuum or by sputtering, and the resist layer applied over the metal, the metal coating imparting elasticity to the composite layer to prevent disruption. A further non-metallic coating may be applied under the metallic coating to increase the adhesion of the latter to the glass. In one way of carrying out the method, a glass plate to be etched is coated with non-metal by vaporizing the non-metal in a vacuum in an electrostatic field (see Group XL (a) ). After cutting the design, etching is carried out by hydrofluoric acid vapour.

Title: Improvements in Mechanically Driven Hack Saws.
Inventor: SHIRTLIFF FREDERICK
IPC: B23D49/00
Filed: 1916-02-28
Abstract: 104,218. Shirtliff, F. Feb. 28, 1916. Reciprocating-saw machines.-Relates to hacksaw machines, and consists of means for relieving the saw on the return stroke, adjusting the pressure on the saw, and automatically stopping the machine. A tension band m passes over a pulley l mounted on the crank-shaft k, and is anchored at one end to a shaft n and at the other to a weighted lever p. A cam on the shaft rocks a lever o and the shaft m on the return stroke of the saw, and so increases the tension of the band m and its grip on the pulley l, which thus raises the saw from the work. The pressure on the saw is adjusted by a sliding bar r, which can be locked in any position by turning it. This is effected by the wedging action of a ball x, Fig. 4, lodged in a longitudinal groove in the bar r and in a groove v at right-angles thereto on the inner face of the guide u. To stop the machine, a belt-fork 2 is moved by a slide 3 under the action of a weight 7 acting through a lever 6; this action is normally prevented by a catch 11 held up to a projection on the slide 3 by a weighted lever 9. An arm 10 of the lever 9 carries a set-screw 13, which engages with a part 14 of the rocking saw support and is so adjusted that, when the work is sawn through, the catch 11 is released. A handle 17 acting through a lever 8 to release the catch 11 enables the machine to be stopped manually. A gauge z facilitates sawing off stock lengths, and a gauge 1. comprising a bar having bent-over ends of identical dimensions and alinement, enables work to be set parallel to the table b and at right-angles to the saw.

A domestic fireplace has behind its firegrate 17 a boiler 10 which has associated with it a burner means for igniting smoke produced by the fire in the firegrate thereby providing heat for the boiler. The boiler 10 consists of a front water receptacle 12 connected by pipes 14 to a back water receptacle 13 which is connected to the usual hot water system by pipes of which one 19 is shown. The two open sides of the passage formed by the receptacles are wholly closed by the burner plates 11 each of which comprises a vertical series of jets 26 supplied with fluid fuel by pipes (not shown) connected to the mains supply. The jets are so arranged that with the usual chimney throat 21 closed by damper 20 (posn. shown), smoke from the grate 17 entering the said passage via duct 16 is ignited by the said jets thereby reducing the smoke particle content of the combustion gas and also additionally heating the water receptacles. The burner plates are of inverted L-shape form each comprising an elongated vertical portion containing the jets and a slightly narrower upper portion 24 (not shown) which serves to define the exit 25 of the combustion gas passage. A hot wire igniter or a pilot jet may be provided for the lowermost jet of each series. The size of the flames may be regulated by means of a tap (not shown) on the supply line. Automatic control of the burner means could be achieved by using some electronic device in conjunction with a means of measuring smoke density. Burner 22 of known construction is used to ignite fuel in the firegrate. The burner means may be of any suitable form such as a plate having a single vertical row of jets and a C- or U-shaped horizontal cross-section. Such burner means could be used with the boiler to define a combustion passage.
