Abstract: ABSTRACT OF THE DISCLOSURE A television receiver is provided with two or more input terminals for receiving respective RF input signals from an antenna and an auxiliary device, such as a personal computer or a video game, and a terminal selector for selecting one of the input terminals. The antenna may receive a plurality of broadcast signals having different frequencies characteristic of respective channels and, for selecting either one of such broadcast signals received at a first input terminal or the auxiliary signal received at a second input terminal and which also has a characteristic frequency, the television receiver has a plurality of manually actuable channel selecting switches and a manually actuable terminal selecting switch mounted on the cabinet of the receiver, and the receiver is tuned for the signal frequency corresponding to the actuated switch. An interlock arrangement insures that only one switch at a time is actuated and enables the operator to select a channel or the auxiliary device in a single actuation. The actuation of the terminal selecting switch is readily indicated to avoid inadvertent actuation thereof. Further, the terminal selector may include a coupling member which, when the terminal selecting switch is actuated to select the second input terminal, actuates a tuning control switch for effecting tuning of the receiver to the signal applied at that selected input terminal.

Abstract: ABSTRACT OF THE DISCLOSURE      A sub-sea well assembly has features to eliminate side-to-side movement between a wellhead and a wellhead housing due to movement of the drilling vessel.   The wellhead  extends  into the  wellhead  housing  and  is connected on its upper end to equipment extending to the vessel.  Slips are located in an annular space between the wellhead housing passage and the exterior wall of the wellhead.  The slips are mounted so that they will slide from the contracted position when the wellhead is being placed into the wellhead housing to an expanded position after the wellhead is locked into the wellhead housing.-In the expanded position,  the  slips move downward  to wedge, but  are  not  weight  bearing.   The  slips  are self-actuating, with a spring to urge them downward into the expanded position.

Abstract: ABSTRACT OF THE DISCLOSURE A video display apparatus having automatic frequency control circuitry for adjusting the frequency of a horizontal oscillator to provide oscillator synchronization with incoming horizontal synchronizing pulses incorporates an interface circuit for controlling the horizontal oscillator frequency response to frequency control output voltage.  The interface circuit incorporates a two-transistor switch which provides a current path for charging the horizontal oscillator timing capacitor during a portion of the horizontal interval and a current path for bypassing the horizontal oscillator timing capacitor during another portion of the horizontal interval.  The amplitude of the frequency control output voltage will determine the relative length of time that each of the transistors is conducting in order to provide a net increase or decrease rate in the charging of the oscillator capacitor, which in turn adjusts the oscillator operating frequency.

Abstract: CLEANING APPARATUS AND METHOD FOR A POLYCHROMATIC ELECTROPHOTOGRAPHIC COPIER       Abstract of the Disclosure A cleaning apparatus and method for removing residual toner from a photoconductor in a color copier.  The apparatus includes a magnetic brush for removing color toner particles from the photoconductor as the different color toner particles serially appear at the cleaning station.  A detoning roller located proximate the magnetic brush has a portion thereof near the magnetic brush electrically biased to strip charged toner particles from the brush.  A plurality of skiving blades serially operate on the detoning roller in accordance with the respective color of the toner particles to remove the particles from the roller.  The portion of the detoning roller adjacent the skiving blades is electrically biased to repel the particles to facilitate their removal.  Each of the skiving blades is associated with a respective collecting means for collecting color toner particles of a respective color.  When toner particles of one color are being removed from the roller, the skiving blades associated with the other colors are moved to a position where they assist in closing off their respective collecting means from receiving airborne toner particles of colors not intended to be collected.  The toner particles collected by the cleaning apparatus are therefore sufficiently free of cross-contamination to permit recirculation to their respective developer stations.

Abstract: ABSTRACT: Method of manufacturing a semiconductor device comprising a semiconductor body, in which a sunken oxide layer is locally provided.           In this method, after a first oxidation mask (21) has been provided on a surface of the silicon body (1), a depression (40) with side walls (41) extending below the first oxidation mask (21) is formed in the silicon body (1).      Subsequently, after the side walls (41) have been provided with a second oxidation mask (70), an oxidation treatment is carried out. According to the invention, the depression (40) is provided in a manner such that the side walls (41) areflat and enclose an angle (42) of 25° to 45° with the original surface, while the second oxidation mask (70) is formed by a 5 to 50 nm thick layer (71) of silicon nitride or silicon oxynitride, which is applied directly or separated therefrom by a layer of silicon oxide (72) having a thickness of less than 5 nm to the side walls. The method leads to a very flat structure.
