Title: Preparation of selenides and tellurides
Inventor: ANDERSON JAMES THOMSON
IPC: C01B19/00
Filed: 1962-05-31
Abstract: Metal selenides and tellurides are prepared by dissolving metal oxides or salts in a solution of an ethylene diamine derivative of acetic acid and thereafter precipitating the required compound by treatment with an aqueous solution of ammonium selenide or ammonium telluride. The preferred ethylene diamine derivatives are ethylene diamine tetra-acetic acid, and N-hydroxy ethyl ethylene diamine tri-acetic acid. The ammonium selenide or telluride may be prepared by decomposing the corresponding aluminium compound in a strong solution of ammonia.  In a modification of the above process, the acetic acid derivative of ethylene diamine is replaced by an aqueous solution of ethylene diamine hydrate.  All the operations necessary for the reaction are preferably conducted in an atmosphere of inert gas, e.g. nitrogen.

Title: Means for joining the paper webs of reels to feed printing presses
IPC: B65H19/18
Filed: 1929-07-09
Abstract: 336,256. James, H. V. July 9, 1929. Feeding webs.-A web-renewing mechanism for a rotary printing-machine having a magazine reel stand is provided with a visual indicator driven through reduction gear from the new reel to indicate a suitable period during the rotation of the reel for the manual actuation of means adapted to cause the expiring web to be pressed into contact with an adhesive portion of the new reel. The reels are carried by frames 3 rotatably mounted on stands 2 and each reel is provided with an indicator comprising a disc 64, driven by a 4-1 reduction gear from the spindle of the reel. Differently coloured arcs 69, 67 represent the pasted and unpasted portions of the circumference of the reel and the leading end of the web is so positioned that the passage of the arc 67 past a fixed pointer 68 corresponds to the passage of the unpasted portion of the reel past devices 40 serving to press the expiring web b into contact with the new reel, any time during that period being suitable to actuate the devices 40. The roll a is brought to the position shown by intermittently operating the motor, which rotates the frames 3 by means of a jogging motor until the reel, by engaging an arm 31, actuates a switch 25 to open the circuit of the jogging motor. The switch 25 simultaneously opens a circuit to de-energize a solenoid 36 and closes a switch in a circuit containing a press-button switch and a solenoid 48. The armatures of the solenoids 36, 48 are connected together and to a lever 41 connected by a link 42 to an arm 43 on a shaft carrying a number of flexible arms 39 terminating in the pressing devices 40. The deenergization of the solenoid 36 allows the devices 40 to fall by gravity to the position shown in full lines. When the joining of the webs is to be effected, the press-button switch is closed at a proper time as shown by the indicator arc 67 thereby exciting the solenoid 48 to cause the devices 40 to press the web b against the reel a. The movement of the core of the solenoid 48 is also caused to close a circuit to a solenoid 55 and thereby operate, by means of a, strip 57, a shaft 59 so as to rotate a number of flexible arms 60 to bring a knife 61 carried thereby into contact with the old web b to sever it. In a modification the devices 40 are actuated mechanically by connections from a hand-lever, one of the connections being adapted to operate a switch controlling the solenoid 55. The feed of the web from the reels is controlled by endless belts such as the belts 6 or the belt system described in Specification 309,819.

Abstract: 756,714. Colour television tubes. RAULAND CORPORATION. July 21, 1954 [July 21, 1953], No. 21258/54. Class 39 (1). A colour television receiver of the shadow mask type has an auxiliary blocking mask 37, Fig. 3, between the shadow mask 38 and the gun and having apertures in registry with but larger than the apertures in shadow mask 38. The auxiliary mask 37 collects about 50 per cent of the beam current and thus prevents overheating of mask 38 so thathigher voltages can be used and consequently a brighter picture obtained. If screen 41 is positive to parallax mask 38 to give port deflection acceleration, auxiliary mask 37 is made positive to 38 to collect secondaries therefrom so as to prevent secondary bombardment of the screen. The auxiliary mask 37 is made by a photo-engraving process comprising contact printing a grill three successive times on the same photographic plate, rotating the grill 60 degrees between exposures, and exposing a cupronickel sheet coated with engraver's enamel through the negative obtained as described above with ultra-violet light. On developing the unexposed enamel washes away and the exposed metal ports are etched away with FeCl 3 . The phosphors may be dot triads, lines or strips and simultaneous or sequential transmission systems can be used. The masks may have aperture diameters of 0.02 inch and 0.01 inch respectively and the masks are spaced by 0.005 incb. Mask 38 is energized by a rectifier energized by an A.C. supply or from the scanning generator, and mask 37 by a separate battery.
