Abstract: A thin wall-mountable unit is disclosed which produces a composite image from a card-like object placed in a slot and a person standing adjacent thereto. The unit includes a pair of lenses for focusing images of the objects on intersecting focal planes. A mirror is mounted in the unit at the intersection of the focal planes. A T.V. camera is employed to sense the composite image resulting therefrom.

Abstract: A connective improvement disposed on the exterior of a cathode ray tube includes the metallic fracture-protective member peripherally surrounding the panel as an integral part of the circuitry connecting the exterior coating on the funnel portion of the tube envelope with appropriate grounding circuitry in the chassis. A discrete deposition of connective conductive material is applied to the exterior of the funnel and panel areas, whereof the funnel disposed section has the exterior funnel coating overlaid thereon. The opposed panel-disposed section makes positive connection with the peripheral protective member, which in turn, has a connective element associated therewith to complete the grounding circuitry without disturbing the intervening conductive material or the funnel coating associated therewith.

Abstract: A yoke mounting apparatus for adjustably positioning a yoke relative to a cathode ray tube and maintaining it in position until it is secured to the tube. The yoke is fastened to an elongated member rotatably mounted on a positioning means that can be moved along three orthogonal axes. A tilting mechanism supporting the tube allows tilting of the tube relative to the yoke. A locking means normally prevents any movement between the yoke and tube. A pneumatic source is used to release only that lock preventing the type of movement desired. All the controls for the apparatus are mounted at the front of the tube so the tube screen can be viewed while the relative positions of the yoke and tube are adjusted.

Abstract: A electronic system develops a rotating raster scan in synchronism with a tating image enabling a stationary image sensor to generate video signals for producing an erect, non-rotating image at a remote location. Sine and cosine signals are synchronously developed with the rotation of the image as a function of the instantaneous angle of the rotation. The sine and cosine signals are combined with linear vertical and horizontal sawtooth deflection signals and applied to the deflection means of the stationary image sensor to produce an erect, non-rotating video image on the face of a remote cathode ray tube display.

Abstract: Multiple layer light transmissive laminates and a method for making them. Such laminates are particularly adapted for use as glazing materials. The laminates retain light transmissivity after exposure to elevated temperatures. The laminates include two or more layers of light transmissive sheets such as glass, polymerized methylmethacrylate and the like, bonded together by means of a thermosetting resin which is cured in the absence of free oxygen and in the absence of oxygen-generating polymerization initiators. The curing is achieved by means of radiation energy delivered through at least one light-transmissive sheet into the resin.

Abstract: An electron - optical - photographic system utilizes the novel qualities of an optical density wedge filter for use with a CRT oscillograph having an optical density along the taper of the wedge equal to the square root of the probability density distribution of a random variable, e.g., "white noise" displayed on one side of the X-axis of the oscillograph. The visual portrayal of the amplitude-time presentation of noise (as on a cathode ray tube) is modified by the filter to produce a uniform gray pattern. Addition of a sinusoidal signal to the noise then results in a clear recognition of the signal even when it is well below the noise level.

Abstract: A pair of television receiver high voltage connectors, connecting the receiver high voltage rectifier to the cathode ray tube anode lead and the high voltage transformer, each include a resilient sleeve in which a cup-shaped contact and insulated wire together with an axially compressible spring are supported within a receptacle, formed by a portion of the sleeve inner surface and the cup-shaped connector. The receptacle expands to accommodate the insertion of the end portion of the high voltage rectifier forming an air-tight enclosure for the connection which is completed by the compression of the spring between the contact and rectifier.
