Title: Head to track alignment in a rotating head magnetic tape unit
IPC: H04N5/7826
Filed: 1974-10-30
Abstract: The position of a length of magnetic recording tape, adjacent a rotating head device is servo controlled to accurately position a transverse tape data track in alignment with the head path. The tape includes a longitudinal servo track. A portion of the servo track is read by the rotating head as it sweeps transversely across the tape. The servo track is formed as a constant frequency pattern having periodic sync marks which define the center of a data track. The rotating head signal constitutes a clock which is used to drive an up/down counter as the head sweeps across the servo track. The counter's counting state changes as the head sweeps the servo track, such that the residual count, which remains after the head leaves the servo track, is a measure of the magnitude and direction of head-to-track alignment.

Title: Process for production of calcium hypochlorite
IPC: C01B11/06
Filed: 1974-11-15
Abstract: A continuous cyclic process for production of calcium hypochlorite wherein an aqueous solution saturated with calcium hypochlorite and sodium chloride is chlorinated by using chlorine gas to produce sodium chloride crystals and an aqueous chlorinated reaction mixture, the formed sodium chloride crystals being then separated from said aqueous chlorinated reaction mixture. First sodium hydroxide is added to the foregoing aqueous solution which solution also contains calcium hypochlorite and sodium chloride in the crystal phase. Then calcium hydroxide and sodium hydroxide is further added to the aqueous chlorinated reaction mixture remaining after separation of said crystals therefrom. This mixture containing calcium hydroxide and sodium hydroxide is again chlorinated with chlorine gas to produce a slurry containing mainly sodium chloride crystals, calcium hypochlorite crystals and a mother liquor saturated with calcium hypochlorite and sodium chloride. The obtained slurry is divided into a first slurry [I] having mainly calcium hypochlorite crystals, sodium chloride crystals and mother liquor saturated with calcium hypochlorite and sodium chloride, and a second slurry [II] containing calcium hypochlorite crystals with a small amount of sodium chloride crystals and mother liquor saturated with calcium hypochlorite and sodium chloride. The second slurry [II] is then treated so as to remove the calcium hypochlorite crystals with a small amount of sodium chloride crystals thus forming a third phase mother liquor [III] saturated with calcium hypochlorite and sodium chloride. This third phase mother liquor [III] and the first slurry [I] is then recycled to the first step, i.e., the aforesaid aqueous solution with saturated calcium hypochlorite and sodium chloride containing a small amount of calcium hypochlorite crystals and sodium chloride crystals.
