Abstract: ABSTRACT OF THE DISCLOSURE           An electron discharge device is known wherein a stream of electrons generatad in an evacuated enclosed and extending over a broad area is passed through a thin window to a region of high pressure outside the enclosure.  This invention improves such a device by positioning between the window and the electron emis-tion means of the device a structure which comprises a generally flat metal plate of high thermal conductance having closely spaced parallel slots extending over and covering the intended area of the electron beam. The bottom of each slot is disposed adjacent one surface of the plate and over its length and is provided with a row of closely spaced holes of the same diameter as the bottom width of the slot. The holes go through the remaining material leaving a small web between adjacent holes.  The window is mounted of the slotted side of the plate while the side of the plate with the holes faces the emission means disposed in the evacuated enclosure.  The plate preferably is provided with coolant flow passages for the continuous removal from the plate of significant amounts of heat generated by the impact of electrons on the plate and by electrons passing through the window.

Abstract: ABSTRACT     In a recording spectrophotometer the ordinate of the plotter-scriber is controlled by she output of a photomultiplier while the abscissa of the plotter-scriber is controlled by a selectable mode manually adjusted controller.        In one mode, the controller furnishes a time base signal of selected rate of change, so that the abscissa of the plotter-scriber varies with the passage of time in accordance with said rate of change.        In another mode, the controller furnishes a stepping signal of selected periodicity, for application to n stepping motor, which changes the wavelength adjustment of the spectro-photometer at a rote determined by the selected periodicity.          The spectrophotometer furnishes to the plotter-scriber an analog voltage varying with the instantaneouw wavelength setting of the spectrophotometer, so that the abscissa of the plotter-scriber correspondingly varies with the instantaneous value of the wave-length A common manually adjusted digital setting means is used for adjusting either the said selected rate of change of the time base or the said selected periodicity of the stepping signal.

Abstract: ABSTRACT OF THE DISCLOSURE      A combined bearing sealing and bearing adjusting subassembly for use with two members which rotate relative to each other upon a tapered roller bearing assembly, such as a belt conveyor idler roll which rotates relative to a stationary shaft upon a pair of axially spaced tapered roller bearing assemblies, and the combination of such a bearing sealing and bearing adjusting subassembly with a conveyor idler roll assembly. A separate cartridge-like subassembly is mounted between the two relatively rotatable members and contiguous each respective tapered roller bearing assembly.  Each cartridge-like subassembly includes a combined contact seal and a labyrinth seal which cooperate to prevent ingress of foreign matter into the corresponding bearing assembly or the egress of lubricant from the bearing assembly.  Each cartridge-like sub-assembly also includes a plastically and elastically deformable collapsible spacer member which absorbs clearances resulting from manufacturing tolerances of components of the idler roll assembly and also by controlled release of the elastic deforma-tion of the spacer member provides a predetermined axial preload or, alternatively, end play adjustment of the corres-ponding tapered roller bearing assembly, as desired.  The collapsible spacer is so characterized that it provides the same axial preload or end play, as desired, without individual selective adjustment, for the bearings of any one of a number of idler roll assemblies in which the components of the respective idler roll assemblies have dimensional variations within a given range of manufacturing tolerances.

Abstract: ABSTRACT     A two-way cable television broadcasting system wherein a single coaxial cable is used to deliver TV and FM programs to many subscribers with each subscriber having a specific allocated band of frequencies for reception of any desired television or FM program and where each subscriber can independently select the program desired to be seen and/or heard which will be delivered to the subscriber over an allocated band of frequencies. The subscriber drops from said coaxial cable are so arranged that they descend in frequency along the length of the feeder cable. Auto-matic switching of any incoming program to any drop is achieved by means of converting all incoming channels to a common I.F. frequency at an amplifier or control station and then deconverting said frequency to the desired outgoing band of frequencies.
