Title: Cathode ray tubes
Inventor: FRYKLUND ROBERT ALDEN
IPC: H01J29/78
Filed: 1962-04-25
Abstract: 1,009,704. Cathode-ray tubes. RAYTHEON CO. April 25, 1962, No. 15807/62. Heading H1D. A cathode-ray tube comprises a gun for producing a plurality of electron beams directed towards different points along an arcuate path on a target, a plurality of grids for independently controlling the electron beams respectively, and a deflection device adapted to deflect the beams cyclically along the arcuate path. In one embodiment, Fig. 1, the electron gun 12 comprises a ceramic cylinder 13 cemented to a disc 14 which contains an indirectly heated cathode 15 positioned in an annular recess in its surface. The electron emission from the cathode is controlled by 48 independent grids 17, each aligned with an aperture 20 in a disc 19 which acts as an anode. An electrostatic focusing electrode structure 23 comprises two concentric cylinders 24, 25, and accelerating electrodes 30, 31, 34, 35 project the beams towards a fluorescent screen 11. With no potential applied to deflection electrodes 38, 39, a circular pattern composed of 48 overlapping elongated spots is obtained on the screen. By deflecting the beams away from the axis of the device in an alternating magnetic field produced by a coil 45, the spots are further elongated so that a circle of larger diameter is produced on the screen. In a further embodiment, magnetic focusing is employed in place of the electrostatic focusing produced by the structure 23. Specification 1,009,705 is referred to.

Title: Improvements in and relating to gyroscopically controlled instruments
IPC: G01C19/42
Filed: 1946-05-27
Abstract: 612,571. Gyroscopic apparatus. SCOPHONY, Ltd., and JONES, P. L. F. May 27, 1946, No. 16080. [Class 97 (iii)] A gyroscope, e.g. a rate of turn gyroscope is provided with friction damping means to prevent continual oscillation of the indicating means or to ensure stability when used for automatic control. The rotor is mounted for rotation about an axis A, Fig. 2, in an inner gimbal 10 which in turn is mounted on a spindle 12 for limited rotation about an axis B in an outer gimbal 11. The outer gimbal 11 can rotate about a spindle 14 on axis C in the frame 13. The rotor axis A is constrained to be normally perpendicular to axes B and C by the springs 15. Spindle 12 is extended at 12<1> and carries a member 16, which may be cylindrical or conical, positioned between, but normally not contacting, two cheeks 17 and 18 fixed to the frame 13. The outer surface of member 16 and the inner surfaces of the cheeks 17, 18 are of non-metallic material such as leather or hard rubber. Indications of rate of turn are given by pointer 19 co-operating with scale 20. Initial acceleration of the frame 13 during a turn or oscillation of spindle 12 about its mean position causes one cheek 17 or 18 to contact surface 16 and the resulting friction sets up the required damping torques. The damping torque may be adjusted by varying the distance between the zones of contact of members 17, 18 with 16 and the intersection of axes B and C. Spindle 12<1> may be mounted .on a separate axis parallel to that of spindle 12 and geared to rotate therewith and cheeks 17, 18 may be constructed as the prongs of a fork.

Abstract: 1465251 Cleaning coke oven doors &c. INDUSTRIAL HIGH PRESSURE SYSTEMS Inc 19 April 1975 16243/75 Heading C5E The mating surfaces of the doors and door jambs of coke ovens are cleaned hydraulically after use by jets of water. When the door has been withdrawn and the oven emptied, a wheeled cleaning unit of the form depicted in Figs. 4 and 5 is introduced into the opening and the operative surfaces of the door jamb 10a are cleaned by opposing jets of water directed from nozzles 33. During the cleaning operation, each head 30 bearing the nozzles 33 is moved up and down along one vertical surface of the door jamb and across the top and bottom in a path defined by a pair of roller carriage members 15 running within a track 14. The required motion forwards and backwards is produced by a reversing motor 22 acting through a chain drive 17. The hydraulic circuitry is of conventional construction (Fig. 1, not shown). The opposing surfaces of the withdrawn door 11, Fig. 6, are cleaned in a similar fashion by jets of water issuing from nozzles 40. According to another embodiment, the spray heads for both door jamb and door may be mounted on the same hydraulically operated telescopic column 70, Fig. 7, in rotatable housings 72. In use, the column is extended and retracted in the vertical direction, the spray heads being positioned horizontally, to clean the vertical surfaces of the door or door jamb. At the upper and lower ends, the spray heads are swung vertically by operation of synchronous electric motors (not shown) so as to clean the horizontal surfaces.

Title: Improvements in or relating to methods of drying hides or skins
IPC: C14B1/26
Filed: 1943-10-08
Abstract: 572,367. Cooling and drying hides. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Oct. 8, 1943, No. 16481. [Classes 29 and 34 (ii)] [Also in Groups VI and VIII] Untanned hides and skins which have been soaked in water or tanned hides and skins which have been kept in a wet or damp condition during tanning and any subsequent operations are dried by freezing and removing water therefrom by sublimation by means of flowing dehumidified air or other gaseous water-absorbing medium under sub-freezing conditions. Untanned hides so dried may be wet back, tanned, and again so dried after freezing. An untanned hide should be scraped free of flesh before soaking, and the soaking water may contain salt or sodium polysulphide to remove soluble protein, but any added agent should be thoroughly washed out before freezing. Drying to 8-13 per cent. moisture is preferred, and the drying protects untanned hides from bacterial action, which may therefore be stored or shipped without further treatment. Drying after tanning gives a soft flexible leather of light colour. Freezing may take place at temperatures between 10‹F. and -110‹F. and drying between 30‹F. and -20‹F. As shown in Fig. 2, the hide 4 is carried on a metal plate 6 and frozen by sprays of brine solution from a distributor 10. Tanned hides are held flat on the plate by a presser member 14, the grain side being against the plate. For drying, Fig. 3, the hides 4 are carried on conveyors 16 through spaces between perforated members 18, and air is passed through the latter by a blower 20, so that both sides of the hides are dried simultaneously. A dehumidifier 22 serves to dry the circulating air which is kept at sub-freezing temperatures.
