Title: Process of manufacture of cutting, piercing, and the like instruments
IPC: B23C5/02
Filed: 1925-12-12
Abstract: 267,587. Ignatieff, A. Dec. 12, 1925. Compound forms; drills and cutters; saws; milling-cutters; taps; screwing-dies; files; lathe and like tools.-In making cutting, piercing and like instruments having a cutting edge formed with two faces, the non-working face is covered with at least two layers of graduated hardness so as to retain the cutting-edge sharp during use. A lathe tool has hard layers 1 welded or otherwise fixed as by clamps and screws to the rear edge of the tool 2. A similar tool or straight tool for planing or shaping may similarly have hard layers on its rear edge. A saw, Fig. 4, or with finer or broader teeth a file, has the hard layers 1 on the rear face of the teeth. In another form of saw having two rows of parallel teeth, Figs. 5 and 7, a soft central layer is covered on both sides with layers of gradually increasing hardness and is then corrugated and planed on its outer surfaces to form hard layers 1 extending in the form of bars or strips from the points of the teeth. This form of saw may be made by casting the bars on to straight layers. A circular cutter of the hob type has its spiral faces covered with the cutting layers. A helical crown borer, Fig. 10, with a conical central channel has four conical teeth and four helical multiple cutting layers 1. A twist drill with cutting layers 1 on the shank 5 has a conical head 6 secured thereto having the cutting layers 1 on its two threads. The rear ends of the head abut against the projections on the shank. Multiple toothed broaches, reamers, helicoidal milling cutters, circular saws or files, screw-cutting taps and dies may be similarly provided with hard cutting layers. A screw chaser, Fig. 13, has cutting layers 1 on its non-working faces. The cutting layers may be applied by electrodeposition or by spraying. Specifications 13011/13, 207,822, [both in Class 83 (iii), Metals, Cutting], and 261,166 are referred to.

Patent GB-651324-A (GB)
Title: Improvements in or relating to printing by means of dyestuff carriers insoluble in water
IPC: D06P5/00
Filed: 1946-10-25
Abstract: Fibrous materials are printed with printing compositions containing dyestuffs incorporated with water insoluble, especially water-repellent, dyestuff carriers, characterized by the fact that the dyestuff carrier consists of a linseed oil varnish or varnish and printing oil, and that all the necessary modification of the dyestuff carrier is produced by treating the printed material with moist steam for a period to render the dyestuff carrier at least in part water-penetrable whereby penetration of the dyestuffs to the fibres is effected.  Any unmodified dyestuff carrier may subsequently be removed with an organic solvent, e.g. trichlorethylene.  The material may be wetted with water before or during the steaming process, and a wetting agent may be added to the water.  In order to fix the dyestuff on the fibres, the printed fabric may be moistened with a solution containing an acid or acid salt before steaming, e.g. lactic, tartaric, oxalic or formic acid may be used.  A neutral substance which will release acid under the action of moist steam may be added to the printing composition, e.g. triacetine.  Acid substances may be included in the moist steam in order to fix the dyestuff on the fibres, e.g. formic acid.  The modification of the dyestuff carrier may be expedited by adding to the printing paste substances which are in themselves soluble in water and act as a connection between the water-repellent dyestuff carrier and the moist steam, e.g. monohydric and polyhydric alcohols.  In example (1) a fabric is printed with Indanthren Brilliant Blue GCD Fine PV, "Rongalite C" (Registered Trade Mark), potash, varnish, aluminium hydroxide and glycerine, is steamed with moist steam and then reoxidized in the usual way, washed, soaped, rinsed and tentered.  A number of other examples are given illustrating the use of various dyes such as vat dyes, acid dyes, wool dyes, acetate dyes, &c. with the dyestuff carriers.

Title: Improvements in locks
IPC: E05B27/04
Filed: 1927-11-25
Abstract: 299,211. Pepper, L. Nov. 25, 1927. Locks, revolving-barrel; wards for; preventing picking of.-Unauthorized opening of radial pintumbler locks by a, tapping pick-lock is prevented by supplementary pin-tumblers 18 at an angle to and on both sides of the usual tumblers 12. Further security may be given by spring-plungers 19 at right-angles to one or more of the supplementary tumblers 18 so that when the barrel 14 is moved to bring these tumblers into line with those 13 in the barrel, the descent, of the tumblers enables the plungers 19 to snap into recesses and lock the tumblers against retraction. This prevents further rotation of the barrel for unlocking and retains the barrel in the partly turned position, indicating tampering. The correct key holds the pins 13 with their upper surfaces flush with the periphery of the barrel and so prevents the supplementary tumblers from coming into action. Further security may be ensured by providing wards 5 in recesses 6 in the barrel, necessitating corresponding cutting of the correct key.

Title: Improvement in slitting machines
IPC: B26D1/22
Filed: 1927-11-25
Abstract: 295,877. Marks, E. C. R., (Cameron Machine Co.). Nov. 25, 1927. Stationary-cutter machines. - In a score-cut slitting machine movement of the discs towards and away from the roll causes simultaneous endwise traverse of the discs, so that a new point of contact is established when the members reengage. Movement of a wheel 33 swings a memher 12 on which the slitting discs are axially adjustable, and a cam 17 actuates a pawl 21 cooperating with a ratchet wheel 22 on a cam 25. The cam 25 engages a stationary pin 27 and is carried bv the member 12. Movement of the discs away from the backing roll causes a small axial movement of the cutter support member 12 and prevents grooving of the roll.

[Class 39 (i)] In a tube for television transmission, the image 3, Fig. 1, is projected on to the inner side of a photo-electric cathode 1, which is not transparent, and the electron image is focused, e.g. by a coil 8, on to a mosaic 5 scanned by a light spot. Mirrors 2, 11 reflect the image and light spots on to the cathode and screen ; the light spot may be produced by a rotating lens disc or by a nipkow disc. An anode 6 is provided. In a modification, the image is projected on to the mosaic screen and the light spot on to the cathode to form an electron beam which scans the mosaic. In another form, the electron image from the photocathode 1, Fig. 2, is concentrated by a negative cylinder 23 on to the aperture in a lens formed by a cone 24 and a ring 25, connected to a wallcoating or cylinder 6, which forms an anode. Dimensions of the electrodes and values of potentials thereon are contained in the Specification. The mirrors 2, 11 are secured as shown to electrodes 24, 25 respectively ; the mirrors may be dispensed with, the light spot and the image being projected directly at inclined angles of incidence. Trapezoidal distortion may be eliminated by adjusting the angles of incidence. The light spot may be produced by means of a Braun tube 29. Specification 489,362 is referred to. The Specification as open to inspection under Sect. 91 also comprises subject-matter which is contained in Specification 489,422. A photoelectric mosaic 5a, Fig. 4a (Cancelled), may be arranged on a transparent layer 5c and is arranged so that the elements are located in the openings of an earthed photo-electric layer 1. A mesh anode 6, Fig. 4b (Cancelled), is connected to the signal amplifier 10 and is positively biassed by a battery 7. The image 3 is projected on to the mosaic 5a and a scanning light spot is projected on to the layer 1, which may be formed by developing a photograph of the mosaic 5a. In another form, a cell comprises a semi-conducting layer 23, Fig. 5a (Cancelled), of selenium or cuprous oxide provided with a transparent electrode 24, which is connected to the amplifier 10, and a mosaic electrode 5a. A " blocking layer " is formed which can be penetrated by electrons in the direction from 23 to 5a when illuminated. The image 3 is projected on to the mosaic 5a and a scanning light beam is projected on to the blocking layer. In a further form, the mosaic electrode 5a, Fig. 5b (Cancelled), is arranged between two semi-conducting layers 23, 23<1>. An electrode 26 is earthed preferably through a battery 7. The electrode assembly need not be contained in a vacuum. This subject-matter does not appear in the Specification as accepted.
