  • Patent number: 8052178
    Abstract: Disclosed is a temporary door lock assembly. The assembly is formed from five major components: a rosette; a bolt; a barrel; a locking arm; and an inside plate. These components are lockingly interconnected without any fasteners or the use of any tools to form a door lock. The lock can be temporarily secured within the lock opening and barrel of a door frame during residential or commercial construction to thereby delay the need to install more complicated and expensive permanent locks.

  • Publication number: 20090119972
    Abstract: A fishing hook device changing fundamentals of ā€œJā€ shape fishing hooks with modifications to the extended shank length only allowing all prior art. Towing eye position relative to hook bend and hook point is changed allowing fish unrestricted access to the forward bait fish head clear of obstruction by the fishing line. Sharpened hook point faces away from the fisherman and cannot snag. This device has a once-only structural shape change only after the hook point impales flesh inside the fish mouth lower jaw. A second version has a re-settable structural shape change after the hook point impales the fish.

  • Patent number: 5742613
    Abstract: A fault tolerant random access data storage system comprises a plurality of rows of memory chips 31 plus a first spare row of chips 32 and a second spare row of chips 33, each chip comprising an array of memory locations. A controller 25 addresses the chips with the logical addresses of the rows within the arrays being skewed relative to their physical addresses but in a different manner for the different rows of chips, and with the logical addresses of the columns within the arrays being skewed relative to their physical addresses but in a different manner for the different manner for the different rows of chips. The locations of faults within the chips are recorded so that if a selected array row in a selected chip row 31 is faulty, then a replacement row in the first spare row of chips 32 is selected instead, and if a selected array column in a selected chip row 31 is faulty, then a replacement column in the second spare row of chips 33 is selected instead.

  • Patent number: 4937807
    Abstract: Method and apparatus for addressably writing digital representations of high-fidelity sound recordings in a non-mapped digital storage device, such as a CD music ROM, using conventional PCM (pulse code modulated) equipment, but in a more condensed and efficiently sampled ADM (adaptive delta modulated) format thereby providing high-density addressable storage of several thousand recordings in a single music ROM jukebox as well as high-speed information transfers. The invention enables communication and control links between conventional digital audio processors and conventional microcomputers. Timing data is embedded in the ADM formatted and blocked data file. The microcomputer is utilized for editing ADM data, inserting catalog data, and transferring the data file to a standard PCM file writer suitable for making non-mapped CD music ROMs containing addressable ADM data files on conventional equipment utilized in the indstry.

  • Patent number: 4811325
    Abstract: Data processing system for high-speed reproduction of musical recordings at a point-of-sale terminal utilizes optical CD music ROM banks of master programs prerecorded by a Dolby ADM (adaptive delta modulated) technique to condense their "information" content. Condensation permits higher data throughput during high-speed reproduction. In a "premastering" process to make encoded masters, a special multiplexer board provides interfacing between Dolby ADM digital audio data and a conventional data processing system. The multiplexer board performs computer-like data blocking and also writes a unique sync code directly in the data block. The data processing system also catalogs and edits the blocked digital audio; places encrypted catalog, pricing, and other indicia in the data file representing the music; and sends the data file to convention 16-bit PCM file writer for making the encoded CD music ROMs which contain the ADM data representing the encoded audio program.

  • Patent number: 4113197
    Abstract: Splicing apparatus for joining the paper web from successive reels in a cigarette or cigarette filter rod making machine includes provision for running each reel closer to the end in a controlled manner to reduce wastage of paper. For that purpose the diameter of the in-use reel may be monitored by an arm coupled to an electrical detector with an averaging or smoothing circuit so that a signal is obtained which is insensitive to reel non-circularity or eccentricity. Alternatively the end of the paper may be detected as a result of the loss of tension in the paper.
