Title: Apparatus and method for using lockout for synchronization of access to main memory signal groups in a multiprocessor data processing system
Inventor: CUTLER DAVID N
IPC: G06F15/177
Filed: 1988-06-30
Granted: 1992-06-02
Abstract: ABSTRACT    In a multiprocessor data processing unit, a data element in the main memory unit, that has system wide significance, can have a requirement that this data element be altered in a controlled manner.  Because other data processing units can have access to this data element, the alteration of the data element must be synchronized so the other data processing units are  not  in  the  process  of  altering the same data element  simultaneously.   The  present  invention includes an instruction that acquires access to an interlock  signal  in  the  main  memory  unit  and initiates  an  interlock  in  the  main  memory  unit, thereby excluding other  data  processing units from gaining   access   to   the   interlock   signal simultaneously.   The  instruction  causes  the  data element  related  to  the  interlock  signal  to  be transferred  to  the  data  processing  unit  where  the data  element  is  saved,  can  be  entered  in  mask apparatus and then have a quantity added thereto. The altered data element is returned to the main memory unit location and the main memory interlock signal is released, thereby completing the instruction.

Title: Method for writing and means for reading position indicating markers on tape
Inventor: NEWELL CHESTER W
IPC: G11B15/08
Filed: 1989-06-01
Granted: 1995-02-14
Abstract: A method of making and of reading markers at control positions on a length of magnetic tape having light-impeding coatings on opposed sides of a transparent tape substrate.  Markers are recorded by directing focused beams to control positions along longitudinal areas of the magnetic tape.  The beams have an energy sufficient to ablate the coatings, but to leave the tape substrate intact.  Raster scanning of the control posi-tion provides rectangular markers at prescribed posi-tions.  An optical splitting element is used in reading the markers.  The element is a heptagonal prism which re-ceives light from a tape drive and forms two parallel, spaced apart beams which are first directed at separate elevations through the markers in the magnetic tape, then converged to the light sensors in the drive.  Preferably the optical path through the prism is a path formed by folding a hexagonal prism, with the fold being a reflec-tive surface.

Title: Non-absorbent litter for use with absorbent pad
Inventor: YANANTON PATRICK
IPC: A01K1/01
Filed: 1989-07-14
Granted: 1993-05-18
Abstract: ABSTRACT OF THE INVENTION The invention relates to the prevention of the odor caused by the action of bacteria on cat urine in a cat litter box. The cat litter box has a base and walls and is provided with a sorbtive-desiccant member for the collection of animal urine. Litter is in direct moisture transfer contact with the sorbtive-desiccant member. The odor prevention process includes the steps of transferringcat urine directly from granular particles, to the sorbtive-desiccant member, sorb-ing the urine in a sorbtive-desiccant member having high surface area and high urine sorbency, dispersing the urine quickly in said sorbtive-desiccant member, and evaporating said urine from said high surface area sorbtive-desiccant memberthrough the granular particles. The sorbtive-desiccant member maintains the urine in a medium which subjects the bacteria in the urine to the effects of drying. The granular particles are non-absorbent particles having sufficiently large diameter to provide sufficient interparticle spacing to permit free flow of urine from the particles to the sorbtive-desiccant member and the free flow of mois-ture from said sorbtive-desiccant member to the air. The base of the litter box prevents urine from leaving one side of said sorbtive-desiccant member. Thereby the bacteria, which are capable of breaking down cat urine, die or become dor-mant and thus prevent significant odor formation.
