Title: Optimized interconnect networks
Inventor: BATY KURT F
IPC: G06F15/16
Filed: 1990-05-07
Abstract: Abstract A multinodal system is one-way interconnected, two-way interconnected or, more generally, (n)-way interconnected, where (n) is an integer.  In a one-way interconnected system, only one connection element couples any two nodes.  Or, put another way, only one communication path exists between every node and every other node.  A two-way interconnected system, on the other hand, has two connection elements coupling each pair of nodes. Likewise, an (n)-way interconnected system provides (n) independent connection paths between each pair. such systems are characteristic in that the relationship between the number of independent buses (b), the number of nodes (v), the number of ports (r), and the degree of interconnectedness (n) can be expressed by the equation   Two-way and (n)-way interconnect arrays may be adapted for use in fault-tolerant communications.
Patent CA-2017861-A1 (CA)
Inventor: KEYAKI KEIICHI
IPC: A44B19/36
Filed: 1990-05-30
Abstract: An apparatus for blocking the release of a slide fastener caused by the movement of a slider. According to the preferable embodiment, this apparatus comprises a pair of sliders, which are provided with a pair of ring-projections respectively, and a pair of engaging members as a blocking member for supporting and ensuring the interlocking of the ring-projections. Then, a pair of studs are provided at the engaging members respectively. When the sliders arranged reversely are moved forwardly to be contacted with each other for closing the slide fastener, the ring-projections are interlocked so that the eyes of the both ring-projections are overlapped. Next, each stud is pushed into the overlapped eyes from each side and engaged to another stud in the eyes so as not to be removed and not to be pulled out. Therefore, the release of the slide fastener caused by the movement of the slider is surely blocked. For allowing the release of the slide fastener, the base of either stud is cut and another side engaging member is pulled out. As so doing, the engaging members are disengaged from each other. Accordingly, the sliders can be moved backwardly away from each other for opening the slide fastener.

Title: Lateral compound torsion suspension
Inventor: KOPIECZEK ANTHONY M J
IPC: B60G21/02
Filed: 1990-07-25
Abstract: ABSTRACT    A suspension system for an automobile includes a compound torsion bar arrangement.  The compound arrangement has a first bar which acts as a sway bar and a second bar which provides an output torque opposite to that of an input torque.   The two bars are arranged to operate together and to be attached to the same location of respective wheel support structures.  Variation of the torsional  characteristics  of  the  two  bars  of  the  compound arrangement allows the roll stiffness to be varied while also varying the forces which tend to lift the inside wheel when the automobile is moving in a curved path.

Title: Dispersant system for making polyvinyl chloride which produces low color chlorinated polyvinyl chloride
Inventor: SHARABY ZAEV
IPC: C08F8/20
Filed: 1990-09-21
Abstract: ABSTRACT           Chlorinated polyvinyl chloride  (CPVC)  is pre-pared from polyvinyl chloride (PVC).   When PVC is made utilizing polyvinyl alcohol,  the  low molecular weight CPVC compound so prepared is colored.   A low molecular weight CPVC compound prepared from PVC that was made in the presence of a cellulose ether instead of polyvinyl alcohol resulted in a very low color compound having a DE of O by definition.   However, a CPVC compound prepared from PVC made in the presence of polyvinyl alcohol re-sulted in a relatively high color (DE 18.51).  During the polymerization of vinyl chloride,  polyvinyl alcohol is replaced  with  the  hydroxypropylmethyl  cellulose  ether having a methoxyl substitution of 15 - 35 percent and a hydroxypropoxyl substitution of from 4 - 35 percent.

Title: Method and apparatus for simultaneously reading both sides of an optical storage disk
Inventor: TAYLOR WILHELM
IPC: G11B7/14
Filed: 1990-11-02
Abstract: METHOD AND APPARATUS FOR SIMULTANEOUSLY READING BOTH SIDES OF AN OPTICAL STORAGE DISK               Abstract of the Disclosure An  optical  storage  disk  reading  apparatus  (10) allows the simultaneous reading of both sides of an optical storage disk (44).  An upper base plate (12) and a  lower base plate  (14)  pivot  about hinges  (22-28) through the action of lead screws (30-32).   The lead screws  (30-32)  are turned by separate stepper motors (38-39)  which drive follower nuts  (34-36)  therealong. The  follower nuts  (34-36)  are interconnected to the baseplates (12-14) by yokes (40-42).  As the lead screws (30-32) drive the follower nuts (34-36), the yokes (40-42)  pivotally move the base plates  (12-14)  about the hinges (22-28).  A cartridge (46) containing the storage disk  (44)  is  loaded  into  the  apparatus  (10)  along receiving channels (48-50).   The channels (48-50) hold the cartridge (46) from movement while the disk (44) is free to move therein with the lower base plate  (14) through an interconnecting drive spindle (20).  The disk (44) is thus positioned parallel to and a fixed distance from  the  lower  base plate  (14)  equal  to the  focal distance of an optical reader (54) thereon.  The upper base plate (12) is positioned parallel to the lower base plate (14) and a variable distance from the disk (44). An optical reader  (52)  on the upper base plate  (12) provides  data  to  the  stepper motor  (38)  associated therewith to move the upper plate (12) to the proper focal distance from the optical reader (52).  When the upper plate (12) moves, the lower plate (14) also moves to keep a parallel relationship therebetween.
