Abstract: Electrical connection for the photocathode in an image intensifier tube, said photocathode being present on the input window of the image intensifier tube, and which input window is secured by means of a layer of vacuum-tight material, e.g. frit, to a metallic cathode flange, which in turn is secured to the outer wall of the image intensifier tube, and in which the electrical conducting lead effecting the connection is passed via the frit layer to the outside of the image intensifier tube, and in which means are provided for keeping the electrical conducting lead clear of the input window and/or the cathode flange at least at one place along its length through the frit layer.

Abstract: A woven stringer for a slide fastener has reinforcing projections integral with molded coupling elements. The reinforcing projections extend only along upper connecting threads of four spaced connecting threads upon which the coupling elements are molded to permit free compressing and flexing of the lower connecting threads.

Abstract: In a rotary earth crumbler having a central shaft (1) with mounting discs (2) fast thereon and an annular series of U-shaped resilient stirrups (3), the leg portions of these stirrups are formed with an outwardly convex curved section (12) which extends into a fixing slot (11) in the mounting disc and is then locked therein by deformation of parts of the slot borders below the mid portion of the curved section, thereby narrowing said slot. The locking may easily be released when needed, viz. by bringing the slot borders back to the original shape.

Abstract: In performing operations on a continuous slide fastener chain at spaced locations therealong, the slide fastener chain is incrementally advanced to successively advance the spaced locations to an operating station. The chain is advanced from a reel which is braked only when a loop of maximum size is sensed in a loop forming mechanism. Tension is relieved in the slide fastener stringer by means of a continuously rotating capstan which will grip the slide fastener stringer to advance the chain and overcome inertia of the reel.

Abstract: A tree medication capsule is disclosed as including a vial having a medication sealed therein by means of an end cap; the vial, medication and end cap constitute a self-contained unit which is inserted into a predrilled hole in a tree. The vial is made of frangible material so that upon breaking, as by a mallet tap on the end cap, the medication is free to escape into the tree.

Abstract: Programmable power supplies are made responsive to beam-index and timing signals in order to automatically control the size and position of the display on a cathode ray tube. The high voltage power supply is also made programmable, responsive to video signal content, to reduce the energy stored in the high voltage circuits. Savings in energy consumption are also obtained by efficiently modulating the target screen of a beam-index type color cathode ray tube. Energy lost at the target screen is less than 10% compared to approximately 70% for a conventional color tube, an improvement factor of 7:1 or more. Taking advantage of the above features, a multi-color display apparatus is disclosed which employs dual excitation of a planar target screen to provide high resolution information in monochrome together with a wide range of colors for enhancement of contrast and for improved information discrimination.
