Abstract: 1,068,885. Mixers; edge-runner mills. NATIONAL ENGINEERING CO. OF CANADA Ltd. June 22, 1964 [July 30, 1963], No. 25670/64. Headings B1C and B2A. In a mixing and pulverising apparatus having a rotary agitator, a compressed air borne additive is introduced in metered quantities below the surface level of material in the mixing container. As shown, an edge-runner mill for foundry sand has mullers 13 and mixing blades 14. Binder is metered from a hopper 21 into a compressed air line 17 by a valve 22 actuated at timed intervals by a pneumatic or electric control 23. The line 17 may enter the container tangentially (Fig. 5) or supply a ring manifold round the base of the container (Fig. 2). The injection of binder may be synchronized with the position of the rotating members by a cam on the cross-head which closes a switch operating on an electropneumatic valve; the period of the closure of the valve and consequently the amount of additive injected may be controlled by a time switch (Figs. 3 and 4). There may be a pair of connected containers arranged for continuous discharge operation (Figs. 3 and 5) as in Specification 905,539. The binder may be metered from the hopper by a valve having two members operating to close alternately the entrance and exit of a valve chamber (Fig. 4) as in Specification 1,023,949 and the air and binder may be injected into the container by a nozzle which can be kept clear by a piston reciprocable by a hand wheel and screw (Figs. 6 and 7).

Title: Improvements in and relating to reproduction processing operations conducted on elements in sheet form
IPC: G03C1/74
Filed: 1964-06-23
Abstract: 1,068,520. Laminates KALLE A.G. June 23, 1964 [June 28, 1963], No. 25974/64. Heading B5N. [Also in Divisions G2 and H1] Two elements in sheet form, to be used in a reproduction process, are caused to adhere together temporarily, while the copying operation is carried out, by giving them an electrostatic charge. A particular application envisaged is to photographic contact printing. The positive and negative sheets are placed in contact, and given an electrostatic charge by means of corona wires. This causes the sheets to adhere firmly together so that they can be handled as a single unit while the exposure is made. The close contact, which may last some hours, improves the sharpness of the image. Several layers may be temporarily bonded together in this way, and if the materials of some of the layers do not accept an electrostatic charge, they are bounded or bonded by layers which do.

Filed: 1955-09-12
Abstract: 782,398. Panoramic telescopes. FARRAND OPTICAL CO., Inc. Sept. 12, 1955, No. 26053/55. Class 97(1) A panoramic telescope comprises an axially symmetrical objective followed on the image side by an aperture stop located on the optical axis beyond the focal plane, and a cylindrical lens adjacent the said focal plane which, together with the objective forms two axially spaced images of the stop in front of the objective at or adjacent which images are two reflecting elements rotatable for scanning the object field to get a panoramic view. In the apparatus described the scanning elements consist of prisms 19 and 20, Fig. 1, each having an internal plane reflecting surface, these surfaces being mutually perpendicular and rotatable about perpendicular axis contained in the surfaces. Fig. 1 shows the arrangement in plan and Fig. 3 in elevation. Rotation of the prism 19 scans the field in azimuth, the prism 20 being arranged to rotate simultaneously about the same axis, as indicated in Fig. 4. Rotation of the prism 20 about its axis scans the field in elevation thus enabling scannng to be effected in polar co-ordinates simlar to those employed in fire control systems. Located behind the objective 3 of the telescope, Fig. 1, are erecting lenses 4, 5 forming the aperture stop and located at the rear focal plane of the objective is a lens formed of a spherical lens 7 and a cylindrical lens 9 having a positive power in the plane of Fig. 3 but no power in the plane of Fig. 1. Accordingly in the plane of Fig. 1 an image 10 of the aperture stop is formed at the first prism 20 and in the plane of Fig. 3 an image 109 of this stop is formed at the prism 19. By this means a large angle of view is ensured. In an alternative the lens 9 may have negative power in the plane of Fig. 3 when the image in this latter plane is formed at the prisms 20 and the image in the plane of Fig. 1 is formed at the prism 19. Fig. 6 shows the mounting of the prisms. The prism 19 is carried by a shaft 56 rotatable about a vertical axis by gears 31 and 55. Prism 20 is supported in a cradle 32 rotatable about the same axis as the shaft 56 by gearing 35 and 53. The rotations effect scanning in azimuth the gears being arranged to rotate the cradle 32 through twice the angle of rotation of the prism 19. Rotation of the prism 20 about a horizontal axis 24 to scan in elevation is effected by suitable gearing driven from a shaft 48.

Title: Process for the manufacture of stable organic acid esters of cellulose
IPC: C08B3/00
Filed: 1930-09-01
Abstract: Cellulose acetates and other organic esters of cellulose are stabilized in the crude esterification solutions by heating to an elevated temperature, for example, 60-100 DEG  C., after neutralization of the acid catalyst and after the addition of sufficient water to prevent changes of the solubility properties of the ester during the process.  In the case of cellulose acetate the quantity of water should be such as to reduce the acetic acid to a concentration of 50-80 per cent.  In examples illustrating the application of the process to cellulose acetate, to the crude solution containing sulphuric acid and sodium bisulphate, sodium acetate is added and afterwards water with stirring, the solution being then heated; to the crude solution containing sulphuric and hydrochloric acids and also acetic acid and ethylene chloride, sodium acetate and water are added, and the solution heated, preferably with the recovery of the ethylene chloride; in both cases the acetate is recovered by precipitation with hot water. Specifications 207,562 and 337,366, [both in Class 2 (ii), Cellulose, &c.], are referred to.
