Patent CA-2041698-A1 (CA)
Inventor: REECE JOHN W
IPC: F16H25/00
Filed: 1991-05-02
Abstract: ABSTRACT OF THE DISCLOSURE      A torque compensated camshaft for operating a valve of each of a plurality of valves of an internal combustion engine, the camshaft having an elongate shaftlike portion and an engine valve operating cam for each of the valves, the valve operating cams being spaced apart from one another along the shaftlike portion.  Each of the engine valve operating cams has an outwardly projecting portion, and the outwardly projecting portions are circumferentially offset from one another about the longitudinal central axis of the camshaft.  The camshaft also carries a compensating cam surface, either in the form of an outwardly facing surface of a separate compensating cam or an inwardly facing surface of a portion of a drive sprocket which is keyed to the shaftlike portion.  The compensating cam surface is adapted to be followed by a spring biased compensating cam follower and has portions which introduce torque pulses into the camshaft which are synchronous with and oppositely directed with respect to the torque pulses that are introduced into the camshaft by the engagement between the valve operating cams and spring biased followers which engage such valve operating cams.

Title: Pigment embedding
Inventor: BRODA VINCENT J
IPC: B44D2/00
Filed: 1991-05-13
Abstract: PIGMENT EMBEDDING                               ABSTRACT          The conventional process of creating art work paintings with wax crayon or oil pastel colours involves the depositing of pigment directly onto a naked working surface, be it paper, canvas, or other surface, without in any way preparing that surface for the deposit of that pigment. In the most general sense, this invention a process of creating art work paintings, departs from the conventional process in that the entire or portions of the working surface are completely impregnated with pigment, which pigment is then scraped, rubbed and added to by further application of pigment which then is shaped into the final painting. This procedure of pigment embedding has several distinct variations which give of varied results; such variations which will be described in the invention.     The advantages of this invention are as follows: greater definition of line, the ability to easily surface mix pigments, coloration, ease of pigment colour gradation, ease of modification of the painting especially in the latter stages of the work, longevity of the final work where the entire working surface is embedded, application to any hot or cold press papers, and the ability to avoid the use of expensive toothed paper.

Title: Machine for cutting nape muscles from a front part of a fish and removing the skin from the same
Inventor: KRISTINSSON SIGURDUR
IPC: A22C25/14
Filed: 1991-06-19
Abstract: ABSTRACT          The invention includes a method and a machine for cutting a nape mus-cle 12 of a fish from a front-part 1 and removing the fish skin 13 from the same, after socalled "cutting" the fish into two parts, front part 1 and rear part.  The method includes moving the front part 1 along a fixed, straight track 21 to vertical knives 29, which cut vertical cuts at each side of the the spinal crest 8, and to horizontal fixed knives 15, a kind of a plough (fig. 7 to 9), which is fixed to the shaft housing 31 of the knife shaft 30.  The plough knife 15 cuts almost horizontal cuts 10 from the spine 5 to the skin 13, but not farther.  The uttermost part of the plough, the plough spade 17 is not sharp and tears the nape muscle 12 from the skin 13, when the skin is pulled forwards through a gap be-tween the plough spade 17 and the sliding table 18 below, whereas the nape muscle 12 is retained by the uttermost part of the plough, the plough spade 17.  The machine thus delivers the nape muscles 12 with-out bones and without skin.  This includes, that the machine cuts the horizontal cut 10 opposite the bones and simultaneously removes the skin from the nape muscle 12, with a tool including a plough 15,16,17 for the flesh and a gap 20 for the skin 13, where the skin 13 is pulled through the gap 20, while the plough spade 17 retains the nape muscle 12 and turns it over sidewards.  For different sizes of fish the cutting unit is fixed into arms forming a parallelogram.  A more simple type cuts the nape muscles 12, but does not remove the skin.

Abstract: Abstract A new and improved battery separator takes the form of a porous absorbent nonwoven fibrous web of water dispersible fibers that incorporates up to 65% by weight of fibers having a high cross-sectional aspect ratio, i.e. a significantly greater width than thickness in the dry fibrous web material.  The fibers are uniformly distributed throughout the web material and anchored therein with the help of a suitable synthetic binder.  The high cross-sectional aspect fibers include, inter alia, collapsible hollow fibers and ribbon fibers.  The high cross-sectional aspect fibers when combined with lower denier solid fibers also provide a synergistic reduction in shrinkage.

Title: Reloadable canister with replaceable film spool
Inventor: WEBER FRANK D
IPC: G03B17/30
Filed: 1991-09-24
Abstract: ABSTRACT      A reloadable film canister includes a light-tight enclosure with an aperture for dispensing film therethrough.  A spool of film may be loaded into the enclosure, and may be removed when the film is dispensed.  In one embodiment of the invention, an encoder (field modulating) disk is included as part of the canister.  In another embodiment the encoder disk is affixable to the film spool and loadable with the film spool into the canister.  The spool is mountable in the enclosure for rotation therein and for dispensing, at each step of a stepper motor, a predetermined length of film corresponding to the motor's step size.  The encoder disk has a plurality of uniformly-spaced, peripherally-arranged segments (elements) detectable by an external detector (sensor), the detector and the stepper motor operating under control of a microprocessor.     Upon rotation of the spool and dispensation of film, the disk provides information, via the detector, to the microprocessor enabling the microprocessor to determine, from the number of motor steps and number of segments detected during rotation, the diameter of the film roll and the length of undispensed film remaining in the canister.
