Title: Methods and apparatus for preparing gravure printing members
IPC: B41C1/05
Filed: 1974-03-20
Abstract: 1459048 Making printing plates CROSFIELD ELECTRONICS Ltd 14 March 1975 [20 March 1974] 12366/74 Heading B6C [Also in Division H4] The cells of a gravure printing surface are formed by directing a beam of energy on to the surface via a rotary shutter while causing scanning movement between the surface and the beam. The shutter is driven at such a speed that it, or an image of it, is substantially stationary relative to the surface during its passage through the beam. No material is removed from the portions of the surface that are protected from the beam by the shutter, and these portions form the walls of the cells. The surface may be of plastics, and be plated with chrome prior to printing. The printing surface may be flat or, as illustrated, in the form of a rotatable drum 10, Fig. 1. Light from a laser 12 is modulated by tonal information from a unit 16, e.g. a photocell scanning an image to be reproduced. The image may be on an extension of drum 10 or on a similar drum. The modulated light passes via a shutter 17 to remove portions of the drum surface. The shutter is formed with at least one ring of square apertures (Fig. 2, not shown) and is so driven that the apertures, or their image if lenses 14, 15 are used, are stationary relative to the drum surface. The portions of the shutter defining the apertures therefore prevent removal of corresponding portions of the drum surface, so forming the walls between the square cells on the surface. The depth of each cell depends upon the modulation of the beam. The second component of scan is provided by moving the laser, &c. or a beam deflector, parallel to the drum axis. The shutter may have several rings of apertures of differing inclinations for the preparation of printing surfaces for colour reproduction, the ring selected corresponding to the colour to be reproduced. Instead of a disc the shutter may be a frustum of a hollow cone or a portion of a sphere, and instead of a laser beam an electron beam may be used.

Abstract: 611,176. Heating air for combustion. OLSEN, W. L. April 24, 1946, No. 12384. Convention date, Oct. 16, 1940. [Class 64(i)] [Also in Groups X and XII] The combustion air for steam boilers, especially marine boilers with forced draught, is heated in an air channel formed by a casing 5 surrounding the smoke uptake 3 and the chimney 4, which air channel communicates at its upper part through radial or tangential channels 6, 7 with an air channel arranged inside the chimney. A spiral vane or plate 16 may be arranged in the space between the casing 5 and the chimney 4 to impart a rotary movement to the air flowing through and may also serve as a distance piece between the chimney and the casing, being secured to only one of these. Air is forced by a fan 12 through a channel 13 which may taper, to the lower part of the casing, passing upwards between the chimney and the casing to cross channels 6 7, downwards through channel 8 and through cross channels communicating with channels 11 leading to the furnaces 2. A damper may be arranged inside of the air channel 8.

Title: Improvements in or relating to spring hammers and the like
IPC: B21J7/12
Filed: 1927-05-09
Abstract: 278,979. Kort, L. May 9, 1927. Power hammers. - The mean position of the tup a of a spring hammer is adjusted, whilst working, by interposing between the crank e and tup a cylinder f filled with liquid, such as oil, and allowing movement of the piston g by opening a valve k. A spring m tends to return the tup to its middle position. When the valve k is opened wide by hand or foot mechanism the tup remains at rest, as the valve is closed it gives light blows and assumes a high or low mean position according to the height of the work. To prevent the valve being closed -when the crank e is in its lowest position and the spring b from being strained by the tup failing to strike the work, a projection n is provided to engage the valve lever. Oil leaking from the lower end of the cylinder f is returned by the action of an extension of the piston rod, pipe p and non-return valve q.

Abstract: 570,257. Forming laminated articles of wood and metal. WATTS. V. E. Aug. 11, 1943, No. 12989. [Classes 145 (i) and 145 (ii)] [Also in Group XXII] A method of producing laminated structures from sheets of wood, or metal, or of either of these combined with sheets of canvas or a fibrous material, consists in laying a number of laminµ 63, Fig. 1, upon a mould 62, which may be shaped to form a ship's hull, aircraft fuselage, &c., and coating all the meeting surfaces and edges of the laminµ with a polymerizable resin. Pressure is applied over a predetermined area of the built-up structure by means of a rubber or rubber and canvas pressure member 11 acted upon by a shoe 16 connected to the piston 52 of a pneumatic or hydraulic jack 51. The pressure member 11 is formed with a chamber 13 which is filled with glycerine, or glycol heated by an electrical heater to a temperature of about 350‹ F., and an outer chamber 14 which is kept cool by a circulating fluid and prevents the bonding from extending beyond the heated area. When the resin is bonded so as to cause adherence of the layers, the pressure member is applied to the adjacent section and so on, the action being similar to an ironing action. The completion of the setting of the resin may be effected separately from the bonding process described. The resins employed are such as produce a water-insoluble, infusible and chemically inert substance not attacked by fungi, such as phenolic liquid or dry resins, concentrated liquid urea resins, and thermoplastic resins may also be used. Steamheating may replace electrical. In a modification of the apparatus shown in Fig. 1, the watercooled outer area of the presser member is replaced by an area of sand arranged in a sack placed over the heated chamber of the presser member which in this case is formed as a blanket of an electrical conductor such as metallic wool in which is embedded an electrical heating element. In a further modification, Figs. 6 and 7, a flexible presser member 111 is used, formed with a compartment 113 containing heated glycerine &c. under pressure, and an outer cooling compartment 114 through which cold water is circulated. A flexible reinforcing cover 131 and restraining straps 132 are used to support the presser member and the straps are held by clamps with anchored turn-buckles. The plies 163 are placed over a mould or forme 161 made of concrete. Two presser members may be arranged in tandem, and in this case only one outer section of each member is cooled, the heated sections being placed in contact.
