Abstract: -1-               RCA 74, 014 IMPROVED ERROR CODING FOR VIDEO DISC SYSTEM            The present invention relates generally to video disc systems, and more particularly to error codes used in video disc systems for encoding and decoding digital information on a recorded video signal.           In video disc systems, certain advanced features maybe implemented by recording digital information along with the video signal. Examples of such advanced features include automatically skipping over locked groove defects, display of program playing time, and automatic end-of-program detection. Copending patent application "IMPROVED DIGITAL ON VIDEO RECORDING AND PLAYBACK SYSTEM" by T. Christopher and C. Dieterich, and assigned to the same assignee of the present invention, discloses a video disc system including a player having a simple, efficient, video-to-digital interface for separating prerecorded digital information from the video signal and how such digital information is used to implement the above-mentioned features.           Additionally, it is important that the digital data read by the player be substantially free of undetected errors. Copending application "VIDEO DISC SYSTEM" by C. Dieterich and assigned to the same assignee as the present invention, discloses a digital data recording and playback system suitable for use with the present invention. The recorded digital format disclosed in the latter above-mentioned patent application comprises a start code, an error code, and information bits. During playback, the video disc player samples digital data encoded on the video signal until a start code is detected. After the start code is detected, the error code and the information bits are clocked into appropriate registers. In a sequential process, the error code and information bits are decoded to determine if there is an error. The decoding process results in a predetermined constant (referred to herein as a remainder) if no errors are detected.           Various hardware configurations are available for decoding a digital message in accordance with the above-mentioned format. Minimum requirements include data storage means for storing received data, error code check means including an error code check register for computing a remainder, means for detecting a start code, means for detecting a valid remainder, and control RCA 74,014 IMPROVED ERROR CODING FOR VIDEO DISC SYSTEM                ABSTRACT           An improved error code used for encoding and decoding data in a video disc system of the type wherein the data format comprises a start code followed by an error code and information bits. The error code is chosen so that the error code check register in the video disc player begins with the start code in the register, and, if no errors are detected after the full message is received, also ends with the start code in the register. This unique code simplifies both the control logic and the decoding logic in the video disc player decoder.

Abstract: Abstract of the Disclosure Lock for a safety belt, with a belt lock into which an insertion tab can be inserted and can be locked by a locking latch, as well as with a pushbutton which can be shifted parallel to the insertion path of the insertion tab against a spring force, and through the operation of which the locking latch can be moved against the force of a compression spring from a locking position into the opening position.  A spring tab which is clamped on one side and is arranged substantially parallel to the shifting path of the push-button is provided as the compression spring.  The pressure of the spring decreases when the pushbutton is shifted into the opening position, as the effective spring length between the clamping point and the point of attach of the force becomes larger.

Title: Prismatic beam rotator for an optical beam projector
Inventor: STEWART GEORGE W JR
IPC: G02B26/10
Filed: 1981-04-13
Granted: 1982-03-16
Abstract: ABSTRACT OF THE DISCLOSURE A beam projector which is controlled to alternately transmit rectangular cross-sectional beams substantially parallel to a projection axis, wherein the beams are respec-tively pulse modulated over a correspondingly distinct pulse rate frequency range to supply yaw and pitch information and are respectively scanned in a direction correspondingly or-thogonal to the cross-sectional length of each beam.  The size format of the beam cross-sections and the angles of scan are controlled according to a predetermined time variable function.  In a first time period, the largest cross-sectional beams are alternately transmitted and the scan angle is de-creased as a function of time, so that a fixed area of detect-able information is available for detection with respect to an imaginary orthogonal reference plane moving along the projection axis at a rate corresponding to the predetermined time variable function.  In subsequent time periods propor-tionately smaller cross-sectional beams are transmitted and the scan angle is continually controlled.  The disclosed embodiment employs the use of a single set of proportionately different size formatted cross sectional laser sources as a radiation generator, a scanning mechanism, a vibrationally modulated Pechan type prism and a fixed focus optical system to effect alternately transmitted beams, of selectable cross-section, orthogonally oriented and scanned with respect to each other.

Abstract: CONTROLLED ORIENTED DISCHARGE                 OF CUPS FROM A           BLANKING AND FORMING PRESS            ABSTRACT OF THE DISCLOSURE     Apparatus and method for discharging, flanged cups in a controlled oriented fashion from a blanking and forming press.  The formed cup is raised to a position slightly higher than the upper face of the drawing die, and moved in a straight line by means of a high pressure air pulse to the inlet of a conduit-like discharge chute. The formed cups are moved through the discharge chute by air pressure issuing from angled slots in the walls of the chute.  The invention is particularly advantageous for use with blanking and forming presses simultaneously producing, a plurality of formed cups in order to discharge the formed cups separately from each station in an orientation substantially the same as that in which the cup was formed.  The invention eliminates damage to the formed cup caused by random bulk handling in conven-tional discharge equipment.

Abstract: DATA COMMUNICATION SYSTEM             ABSTRACT      A data communication system for use in the control and monitoring of mobile stations, for example, in a bus monitoring system, from a central station over a communication channel carrying both data and voice information.  Information is encoded into digital messages having a start code followed by one or more data blocks.  The start code identifies the beginning of the data block that follows and enables syn-chronization of clock circuitry to the received data frequency. The data blocks have N digital words with M binary bits where one word is a parity word and N-1 words are data words.  Each of the data words has a data portion and parity portion coded for correction of at least one error.  Relia-bility is enhanced by a data detector which discriminates between data and noise or voice to provide an indication of the presence of data.  In transmitting the digital messages, the bits of the N words in each data block are interleaved to provide protection against error bursts.

Abstract: ABSTRACT OF THE DISCLOSURE A process for compression rolling of thermoplastic sheet material such as polyethylene or polypropylene which involves passing the material between cylindrical rollers having surfaces constituted of lubricative material selected from the group consisting of polytetrafluoroethylene, polyamides, polycarbonates, polyacrylates, polymethacrylates, graphite and molybdenum sulfide, under boundary lubrication conditions to effect a reduction in the original thickness of the material of between about 5 and 95 percent in a single pass. The circumferential speed of the rollers is maintained essentially equal to the linear speed of the thermoplastic sheet material passing therebetween and the film rewind tension is maintained in the vicinity of the elastic limit of the material exiting from the rollers. The process is useful in that it can be carried out by continuous cold rolling, i.e., at ambient temperature.
