摘要： A novel optical assembly is disclosed for use in an ultra-compact, jack-in-the-box projection television receiver. The stationary optical assembly is permanently installed in a lower portion of the cabinet for forming a television image, and projecting an aerial image of the television image upwardly a predetermined image projection distance along an optical path folded by optical path folding means. The receiver includes a unitary optical assembly having a viewing screen selectively storable in the cabinet and elevatable therefrom for receiving and displaying the image. The stationary optical assembly comprises the following, in combination: an image source means for forming the television image, a cathode ray tube holding assembly, and mirror means to reflect the aerial image steeply upward along the folded optical path. Also included are chassis means for receiving and supporting the image source means, CRT holding assembly, and mirror means. The optical assembly according to the invention may also find application in a receiver in which the unitary optical assembly is fixed in permanent elevation from the receiver cabinet.

摘要： To hold three CRTs in proper optical alignment in a projection television system, each of three pods holds one CRT. Each pod includes a cylindrical housing for holding the front piece of a CRT, and a back cover which holds the CRT inside the housing. Preferably, each housing is adapted to hold its CRT at a preselected rotational position and at a preselected tilt angle with respect to a straight ahead optical projection axis.

摘要： A surge protector or arrester for providing surge protection for relatively low voltage or secondary equipment, circuits and systems includes a vertically stacked, parallel arrangement of two, independent, spark gap and valve block assemblies, the components of which are generally horizontally disposed within a triangularly shaped surge protector housing. The triangular shape of the housing enables maximum spacing of the three electrode contacts associated with the two assemblies to prevent their flashover while maintaining minimum exterior housing dimensions. The components of the two assemblies are disposed horizontally within the housing after a sealing and insulating compound has been applied to the entrance portions of the three contacts. Each of the three contacts includes an integrally formed crimp contact, an integrally formed lead-in electrode and an integrally formed spring contact. A plurality of novel spark gap electrodes and a plurality of expansion chambers, spaces or reservoirs are provided within the housing to enable hot, highly pressurized, ionized gases formed during the discharge operation of one or both of the assemblies to expand and cool to thereby prevent flashover of two or more of the contacts.
