Abstract: ABSTRACT OF THE DISCLOSURE          A self-routing switching system connected between input highways and output highways, includes conversion modules, doubled SRM networks, output modules, and first and second selectors.  Normally, one of the SRM networks is connected between the conversion modules and output modules through the first and second modules.  When a request to switch the active network to the other SRM network, the first and second selectors switch connections to the conversion modules and output modules so that the other SRM network is connected between the conversion modules and output modules.  Before actually switching the connections, it is determined whether or not all cells have been discharged from the active SRM network.

Granted: 1994-06-21
Abstract: VALVE TRAIN WITH LASH/COMPLIANCE COMPENSATION Abstract of the Disclosure Modified cams and cam followers are designed to remove lash arising from clearances and compliance in valve train components.  The cam followers have a crowned cam contacting surface having a crest, and the cams have a relief formed in a part of the base circle opposite the lift profile.  The relief extends across the area opposed to the crest so that in the region of the relief, the cam engages the follower in a path offset from and lower than the crest.  The cam regions remote from the relief contact the follower on the crest.  When the cam moves from the offset contact to the crest contact the valve train will be compressed just enough to remove the compliance prior to lift profile engagement.  If any lash is present, it is also removed by the same action.

Abstract: A compact padding machine for screening and conveying soil into a trench. The machine is usable as an attachment to a conventional bucket loader, bulldozer or other base machine. The padding machine includes a screening belt, an underlying inclined conveyor belt, and a transverse, extendible discharge conveyor belt. Soil is collected and conveyed upwardly on the screening belt. Fine grained soil passes through the screening belt, is deposited onto the inclined conveyor belt, and is discharged therefrom onto the transverse conveyor belt, from where it may be conveyed into an adjacent trench. A hydraulic vibrator is coupled to the screening belt to disaggregate clod of fine-grained soil and cause the soil to pass through the screening belt. Rocks and other large objects are conveyed to the rear of the machine and discharged. An auxiliary attachment may be used to collect discharged rocks and convey them away from the path of the following base machine, either by conveying them into the trench, on top of the screened soil, or by conveying them to the opposite side of the padding machine, away from the trench. A pivotable auxiliary conveyor belt is also available to enable screened soil to be discharged at variable distances from the machine.

Title: Pipe coupling
Inventor: STRAUB IMMANUEL
IPC: F16L17/02
Filed: 1991-06-05
Granted: 1994-02-01
Abstract: Abstract The pipe coupling having an elastomer sealing sleeve which is approximately C-shaped in cross-section has a cylindrical housing which is split in the longi-tudinal direction, has end walls bent inwards and can be constricted like a pipe clip by means of a closure having tensioning screws, in which arrangement the sleeve, which is enclosed at the end faces and at the circumference by the housing and by a metal insert sheet bridging the housing gap and is  approximately C-shaped in cross-section, is compressed in the circumferential direction and is brought to bear against the pipes to be coupled. Sliding rings compressible in the circumferential direc-tion are located between the end faces of the sleeve and the end walls of the housing, which sliding rings, upon assembly of the coupling, are brought to bear against the outer walls of the pipes and form a sliding seat with the latter. This leads to the increase in insensitivity to changes with regard to the relative position of the sealing parts and the parts to be sealed, the existing adaptability of the coupling to irregular pipes at the same time being further increased.

Title: Dynamic bus arbitration with grant sharing each cycle
Inventor: MARENIN GEORGE BOHOSLAW
IPC: G06F13/14
Filed: 1991-08-28
Granted: 1996-05-14
Abstract: Apparatus and method for optimizing bus arbitration during direct memory access (DMA) data transfers across a nondedicated bus between a memory and/or a plurality of external  devices  each  master  having  an  arbitration priority.   At  least  two  nonoverlapping  clocks  are provided per transfer cycle and there is at least one transfer  cycle  per  arbitration  cycle.   Arbitration priority  requests  are  transmitted  from  each  external device to an arbitration bus only at the rise of the first clock.  At the end of the last clock, the priority code of the external device having the highest priority is determined to designate the external device which is to become bus master.  Addresses and data are transferred between  the  designated bus  master  and the  memory or another of the external devices via the nondedicated bus during the next cycle after a then active bus master relinquishes  control.   The priorities  of the  external devices can be changed dynamically.  Arbitration cycles are pipelined in such manner that there is no loss of address or data transfer cycles.   The then active bus master may extend the number of cycles during which it communicates with one or more external devices.  A device designated as next in line as bus master may be preempted under a certain condition.

Title: Wide strip diode laser employing a lens
Inventor: SIZER THEODORE II
IPC: H01S5/026
Filed: 1992-09-30
Granted: 1997-10-14
Abstract: An improved diode laser is attained by augmenting the conventional diode laser structure with a cylindrical lens that arrests the divergence of the beam in the spatial direction where it is rapidly diverging. To properly arrest the divergence of the beam and to thereby circularize it, the cylindrical lens is placed at a point in space where the size of the laser beam in the two orthogonal spatial directions is substantially the same. With proper selection of the lens' focal length, the nearly circular cross section of the light is maintained as it travels away from the diode laser. The diode laser is further improved by making the diode structure facet that is closest to the lens highly transmissive, and forming a partially reflective facet on the other side of the lens. This elongates the resonsance cavity.
Patent CA-2082291-C (CA)

IPC: B01D3/14
Filed: 1992-11-06
Granted: 1996-08-13
Abstract: This invention relates to an improvement in a process for the separation of a multi-component stream by distillation.  A multi-component feed is introduced to a multicolumn distillation system comprising a first or main column and a side column wherein at least a light component A is separated from a heavier component C in the first column, the lighter component A being removed as an overhead fraction and the heavier component C being removed as a bottoms fraction.  In the distillation of a multi-component stream containing more than two components, e.g., components A, B & C or in the distillation of a binary stream containing components A & C and volatile impurities I for producing at least one component having dissimilar purity a side column is used for such separation and recovery.  The improvement for enhanced recovery of a component in the side column comprises withdrawing a liquid fraction from the main or first column at a point intermediate the overhead and bottoms and introducing that liquid fraction to an upper portion of the side column.  Lighter components are withdrawn from the side column and returned to an optimal location in the distillation system, typically the main column.  Reboiling in the side column is effected by removing a portion of the liquid typically from the bottom of this column and vaporizing this fraction against a vapor fraction obtained from the main column.  At least a portion of the vapor fraction from the main column is condensed and liquid is returned to an optimal point in the main column distillation system.  The vapor fraction withdrawn from the main column and used to vaporize the bottoms of the side column is withdrawn at a point below the liquid removal point for the liquid feed to the side column.

Abstract: On décrit un procédé et un appareil d'inspection électromagnètique transitoire servant à inspecter des objets au moyen de détecteurs mobiles. L'appareil (13) comprend une partie de détection (27) qui est pourvue d'une antenne d'émission (29) et d'au moins une antenne de réception (31). Las partie de détection (27) est placée à proximité de l'objet devant être inspecté, de sorte que les antennes (29, 31) soient contiguës à l'objet. La partie de détection (27) est déplacée le long de l'objet alors même que l'antenne d'émission (29) induit simultanément du courant dans la paroi et que l'antenne de réception (31) produit un signal de réception en fonction de la diffusion de courant induit dans la paroi. Comme les antennes (29, 31) se déplacent au cours de l'acquisition des données, la vitesse d'inspection est accrue. Les données sont alors interprétées afin de déterminer l'épaisseur de l'objet.

Abstract: Le piège comprend un bâti et une paire de mâchoires montées de façon pivotante au bâti. Chacune des mâchoires peut être déplacée entre une position ouverte et une position fermée où les mâchoires sont contre une patte de l'animal à capturer. Les mâchoires sont dépourvues de dents ou de portions acérées afin de ne pas blesser un animal capturé. Un lacet, pourvu d'une boucle anti-retour et ayant une extrémité ancrée à un arbre ou une racine, est disposé sous les mâchoires afin de se serrer autour de la patte de l'animal. Lors de l'utilisation du piège, l'animal qui se fait prendre cherchera à s'enfuir, ce qui aura pour effet de déplacer le piège. Toutefois, étant donné que le lacet est ancré, il se refermera sur la patte de l'animal afin d'empêcher sa fuite. Ce dispositif permet donc la capture des animaux sans les blesser gravement, comme c'est le cas avec des pièges à mâchoires usuels.
