Patent CA-2007100-C (CA)
Inventor: SAUER HEINZ
IPC: F16B2/20
Filed: 1990-01-04
Granted: 1994-08-16
Abstract: An expandible annular elastic strap has a circumferentially slotted first end portion, a tongue-like second end portion which extends into the slot of the first end portion, and an intermediate portion composed of an outwardly projecting circumferentially extending median section and two marginal sections which flank the median section.  The width of each marginal section need not exceed and can be less than half the width of the second end portion, and the three sections of the intcermediate portion of the strap extend all the way from the first to the second end portion.  The median section of the intermediate portion can be provided with one or more circumferentially extending slots which taper in opposite directions.  The median section reduces the area of contact between the external surface of a clamped hose and the intermediate portion of the strap.  In addition, the median section increases the moment of resistance of the intermediate portion and thus contributes to more uniform distribution of clamping force all the way around the clamped portion of a hose which is to be maintained in sealing engagement with the external surface of a nipple or pipe.

Title: Mechanism for inverting carrier
Inventor: OSHIDA MAMORU
IPC: B65G47/252
Filed: 1990-02-13
Granted: 1998-07-07
Abstract: An inverting mechanism according to the present invention comprises an inverting body for inverting which includes a plate member fixed to each of a plurality of carriers connected to an endless chain and four inverting elements rotatably supported on each plate member at circumferential positions spaced equidistant from each other, and an inverting cam provided on a rack rail on which the inverting elements roll.  The inverting element on the body traveling on the rail drops into a groove formed in the inverting cam to rotate the body about the dropped inverting element as another inverting element rolls along a projection on the reversing cam to downwardly direct the top opening of the carrier and thereby an article to be transferred can be taken out of the carrier.

Title: Compact circuit breaker with an electronic trip unit
Inventor: MEINERS DAVID JOSEPH
IPC: H01H71/02
Filed: 1990-02-22
Granted: 1999-12-28
Abstract: A compact current limiting circuit breaker with an electronic trip unit arranged within the circuit breaker cover and current transformers in the circuit breaker case incorporates reinforcement ribs in the cover to provide added strength. The cover also includes line terminal plugs that removably attach to the cover for preventing inadvertent access to the circuit breaker line terminals when the circuit breaker is energized. Protrusions formed on the bottom surface of the circuit breaker cover under the trip unit provide further strength while cooperating with flexible pads on the top of the current transformers to automatically compensate for manufacturing tolerances.

Title: Method and apparatus for pipelined parallel rasterization
Inventor: BIRK YITSHAK
IPC: B41J5/30
Filed: 1990-10-29
Granted: 2001-04-24
Abstract: A rasterizer 10 for converting a datastream 12 which describes a page to be printed into a rasterized pagemap bitstream 13 to be sent to a printer. The rasterization is done in four stages using parallel processors in all stages except the first, and pipelining the processors between all of the stages. In the first stage 11, a scan processor 14 identifies and stores state-independent blocks 14 in the datastream. In the second stage 17, parallel block processors 22 convert the scanned blocks into stored intermediate-form data objects 20 and request preparation of often-used resources such as characters.      In the third stage 23, the objects are sorted and stored by geographical region of the pagemap by parallel sort processors 24. In the fourth stage 31, the sorted objects are rasterized into pelmaps and placed in the pagemap by parallel bin processors 30. All four stages are pipelined. End-of-block markers are used in the third and fourth stages to maintain correct ordering of the objects within the final pagemap. The rasterizer uses general purpose microprocessors for all stages.
Patent CA-2033780-C (CA)
Title: Thin, dielectrically isolated island resident transistor structure having low collector resistance
Inventor: BEASOM JAMES D
IPC: H01L21/331
Filed: 1991-01-08
Granted: 1996-07-30
Abstract: The occupation area and thickness of dielectrically isolated island-resident  transistor  structures,  which  employ  a  buried subcollector for providing low collector resistance at the bottom of the island, are reduced by tailoring the impurity concentration of a reduced thickness island region to provide a low resistance current path from an island location directly beneath the base region to the collector contact. The support substrate is biased at a voltage which is less than the collector voltage, so that the portion of the collector (island)  directly beneath the emitter projection onto the base is depleted of carriers prior to the electric field at that location reaching BCVEO,  so as not to effectively  reduce  BVCEO.  Since  the  support  substrate  bias potential depletes some of the region of the island beneath the base region of carriers, the doping of the island can be increased compared to the case where the substrate is not biased, while maintaining the electric field at this location less than the BVCEO field.

Patent CA-2063116-C (CA)
Inventor: ITO KENGO
IPC: B41M5/39
Filed: 1992-03-16
Granted: 2002-01-15
Abstract: A method for forming images by a thermal transfer process.      The method comprises the steps of providing a printing sheet having an image-receiving layer on one side thereof, providing an ink ribbon having a dye layer comprising a hydrophilic cationic dye, contacting the ink ribbon with the image-receiving layer, and applying a thermal energy to the ink ribbon in an imagewise pattern to thermally transfer the dye from the ink ribbon to the image-receiving layer. The image-receiving layer comprises at least a layer compound which has ion exchangeability with the cationic dye, so that the dye image is fixed through the ion exchange. Since the dye is bonded to the layer compound through ion exchange, the dye is fixed comparable to that of silver salt photography. A thermal transfer system using the ink ribbon and the printing sheet is also described.

Title: Method and apparatus for fragmenting a block of frozen vegetable tissue
Inventor: NOLIN RICHARD
IPC: B02C1/10
Filed: 1992-04-07
Granted: 1997-05-27
Abstract: An  apparatus  for  fragmenting  a  block  of  frozen vegetable tissue such as peat moss, without causing wide-spread  damage  to  the  individual  vegetable  fibers, comprising a pair of planar jaw members movable between opened and closed positions.   Each jaw member has a grating-like  configuration defining  a  plurality  of discharge apertures in a spaced apart relationship and also comprises projecting crushing teeth.  In the closed position, the jaw members are in a mating relationship, whereby the crushing teeth of each jaw member deeply penetrate the discharge apertures of the opposite jaw member.  In operation, a block of frozen vegetable tissue is loaded between the jaw members while they are in the opened position.  The jaw members are closed for bursting into fragments the block of frozen vegetable tissue under the effect of multiple pressure points created by the crushing teeth on the block surface and for expelling the fragments through the discharge apertures.  The invention also relates to a novel method for fragmenting a block of frozen vegetable tissue without causing wide-spread damage to the individual vegetable fibers.

Filed: 1992-05-20
Granted: 1995-04-18
Abstract: A tree delimber having a boom slidably mounted in a sleeve and means for moving the boom relative to the sleeve.   Tree feeding means are mounted on the sleeve, movable between a closed tree feeding position and an open tree receiving position.  There are tree gripping arms on the front of the boom and tree delimbing arms on the front of the sleeve.  Both gripping and delimbing arms can be selectively positioned in one of: a tightly closed position to clamp a tree;  an open tree receiving position;  and a lightly closed position to loosely hold a tree.  As the tree feeding means move a tree past the delimbing arms to delimb it, means are provided for sensing any stoppage of tree travel.  On sensing stoppage, means initiate gripping of the tree by the delimbing arms and delimbing of the tree by the gripping arms.  The invention also covers a method of delimbing with the above machine.
