Title: Improvements relating to the production of etched glass surfaces
Inventor: HOLMAN HERBERT EDWARD
IPC: C03C15/00
Filed: 1948-07-03
Abstract: 654,708. Half-tone screens. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 3, 1948, No. 17930. [Class 98 (ii)] [Also in Groups XXII and XL (a)] A metal mesh of very fine pitch, whose filaments are of triangular cross-section, is applied to one surface of a glass plate with the base of the triangle in contact with the glass. The assembly is placed in a vacuum chamber and baked to de-gas it. A resist of gold, platinum, &c., is then evaporated through the interstices of the mesh on to the exposed areas of the glass surface on which the mesh is mounted. The mesh is then removed leaving on one surface of the glass plate a pattern of metal squares corresponding to the interstices in the mesh, and this surface is then exposed to an etching agent such as hydrofluoric acid. This may be effected by placing the glass plate over an aperture in a chamber in which high temperature hydrofluoric acid is present, an electric heating coil being provided in the vicinity of the glass plate to maintain its temperature above the condensation temperature of the acid vapour. The etching is continued so as to form deep grooves in the glass plate. The metal resist is then removed and a metal layer is evaporated on to the lands, i.e. the top surfaces of the protuberances, and also on to the bottom of the etched grooves. The metal evaporated on to the lands is then rubbed off, leaving the mesh at the bottom of the grooves, the conductivity of which may be increased by electroplating more metal on to it. The invention is applicable to the manufacture of glass screens for use in the half-tone process of photographic reproduction. Specifications 458,675, 598,994, [both in Group XXII], 620,033 and 634,318, [both in Group XL (a)], are referred to.

During their passage forward the leaves are straightened against the depending curved portions 15 - 20 of the fingers. The plane, of the fingers may be inclined to cause the butt end of the leaves to be aligned against one side of the frame 8. The fingers or claws may be arranged to rise and fall alternately through a sloping table,. A series of upright claws may be mounted on a bar given a circular movement and projecting through a table comprising a series of parallel bars.

Title: A new or improved needle for use in making rugs and for other purposes
IPC: D05C15/06
Filed: 1934-06-19
Abstract: 433,400. Rug needles. JONES, K. W., Ladock, Upper Mulgrave Road, Cheam, Surrey. June 19, 1934, No. 18117. [Class 112] A tufting needle for making rugs and the like has a fixed member co-operating with a sliding clutch member to grip the wool at certain points and stop the feed. In the form shown in the Figures, the stop is an inturned part 6 of the channel-shaped needle 1 and the clutch 5 is a sheet metal slider on the needle. In operation, the needle is threaded with wool 11 which passes through the eye 2, the clutch 5 being held to the rear of the depression 7 in the needle till the required length of wool has been pulled through the eye. The clutch is then released when the tension in the wool pulls it to the position shown in Fig. 5, holding the wool against further feed through the eye. The needle is pushed through the backing to make the first loop, the backing engaging the clutch and pushing it back to its wool-freeing position, the clutch being stopped by a rear-stop 9. The needle is then partly withdrawn, the free end of the wool being passed by the operator through the bight of wool between the backing and the eye, the withdrawal of the needle being then completed. The friction of the wool during withdrawal causes the tongue 8 of the clutch to nip the wool between itself and the stop 7 to pull tight the bight. The operation is then repeated. A second rear clutch may be provided to determine exactly the length of loop formed by each stroke of the needle.
