Patent CA-2106024-A1 (CA)
Inventor: DEDIO EDWARD L
IPC: G03C5/58
Filed: 1993-09-13
Abstract: A photothermographic element comprising a photosensitive silver halide, an organic silver salt and a reducing agent in concentrations such that imagewise exposure to actinic radiation generates from the silver halide a catalyst which accelerates an image-forming reaction between the organic silver salt and the reducing agent is processed by a method comprising the steps of (1) imagewise-exposing the element to actinic radiation to form a latent image therein, (2) subjecting the imagewise-exposed element to a first heating step at a temperature and for a time sufficient to intensify the latent image but insufficient to produce a visible image, and thereafter (3) subjecting the element to a second heating step at a temperature and for a time sufficient to produce a visible image.  This method of "thermal latensification" serves to greatly reduce the significant speed losses that were heretofore encountered with photothermographic elements when considerable time was allowed to lapse between exposure to actinic radiation and generation of the visible image by heating.

Title: Eye filtration prosthesis for relieving intraocular pressure
Inventor: PRICE FRANCIS W JR
IPC: A61F9/007
Filed: 1992-08-14
Abstract: A technique and device for relieving intraocular pressure with a reduced risk of inflammation that may be caused by retrograde flow back into the eye. A unidirectional drainage device (50) is implanted which allows fluid flow away from the eye with a minimal pressure gradient (5 mm Hg. or less), and includes means to prevent retrograde flow. When implanted, the drainage passageway is initially restricted by a flow restrictor (53) at a point downstream from the minimal pressure gradient unidirectional valve (56).  Between valve (56) and flow restrictor (53) is a drainage trap (57) in which debris is receivable without restricting the operativeness of valve (56). After fibrosis has occurred to prevent excessive drainage that might cause hypotony, flow restrictor (53) is removed to allow the free flow of fluid away from the eye, with inflammatory debris being prevented from reentering the eye.

Title: Temperature control in extruders
Inventor: PANDIT MADHUKAR
IPC: B21C23/00
Filed: 1994-03-25
Abstract: The process described gives a process for the cyclic control of extruders and facilitates the precise control of an extruder to achieve maximum output and at the same time optimal quality of the extruded profiles. To do this, the extrusion velocity is controlled in such a way that the profile exit temperature is constant and equal to a prescribed temperature run. Thereby the extrusion velocity and the profile exit temperature are measured over the complete cycle interval for each and every cycle k, and with the knowledge of the relationship between these quantities and the run of the extrusion velocity of the cycle k, the run of the extrusion velocity for the (k+ 1 )th cycle is determined, such that the control error and the control effort are as low as possible and after completion of the (k+ 1 )th extrusion cycle the whole process is repeated for every subsequent cycle till the whole extrusion programme is completed. The process is especially suited for the manufacture of extruded profiles of metals with low and/or wavelength dependent emmissivity and/or variable surface charakteristics, in particular for the manufacture of extruded aluminium and aluminium alloy profiles.

Title: Method and apparatus for producing electrical energy within the body of a ruminant
Inventor: O'GRADY GERALD E
IPC: A01K11/00
Filed: 1994-06-07
Abstract: The need to positively identify ownership of cattle is well recognized and understood and has given rise to the practice of hot iron branding. This method, however, has proven less than satisfactory and a variety of alternate methods have been explored with varying degrees of success. One such method utilizes a transponder encased in a pellet and depos-ited in the cow's reticulum where it remains until slaughter. This method, lacking an active source of electrical energy, is severely limited in its range of data transmission and in addi-tion is unable to power other sensors for monitoring various bodily functions such as tem-perature. The present invention discloses a method and apparatus which overcomes these shortcomings by providing an active source of electrical power within the reticulum of the animal and which comprises an elongate, cylindrical zinc tube closed at one end and hav-ing an integral dividing wall with an elongate solid carbon rod extending coaxially therethrough. A first chamber in the zinc tube is coated with an insulating material such as plastic, which insulating material seals the carbon rod's passage through the dividing wall. The zinc tube first chamber is filled with a compaction of Manganese Dioxide which com-pletely encases the carbon rod. A membrane, porous to the animal's digestive fluids cov-ers the opening in the zinc tube and admits digestive fluids into the first chamber. The structure thus formed is essentially a single electrochemical cell capable of generating electrical energy. A second chamber in the zinc tube houses electronic circuitry which boosts the electrical power output of the cell to levels usable by a variety of additional electronics capable of monitoring bodily functions and transmitting this information along with animal identification information to a base station within a range of between 20 and 30 feet.
