Abstract: An apparatus and method for burning organic material including farm bedding waste of the present invention includes a firebox (14) having an air injector (22) disposed within the firebox (14). A heat exchanger (20) is also disposed within the firebox (14) above the air injector (22). The fuel (18) to be burned, a mixture of organic farm bedding waste, is piled in the firebox (14) surrounding the air injector (22) and heat exchanger (20). By injecting air into the pile of fuel, the fuel is burned from the inside out, surrounding the heat exchanger (20) with the burning fuel. The unburned fuel acts to insulate the burning fuel from the walls of the firebox (14). The apparatus can be used as an incinerator, a furnace to heat a building, or any other use requiring the generaion of heat.

Title: Coin discrimination apparatus and method
Inventor: GERRITY DAN
IPC: G07D3/12
Filed: 1997-06-27
Granted: 2003-08-12
Abstract: A coin discrimination apparatus and method is provided. Coins, preferably after cleaning, e.g. using a trommel, are singulated by a coin pickup assembly configured to reduce jamming. A coin rail assists in providing separation between coins as they travel past a sensor. The sensor provides an oscillating electromagnetic field generated on a single sensing core. The oscillating electromagnetic field is composed of one or mare frequency components. The electromagnetic field interacts with a coin, and these interactions are monitored and used to classify the coin according to its physical properties.  All frequency components of the magnetic held are phase-locked to a common reference frequency. The phase relationships between the various frequencies are fixed, and the interaction of each frequency component with the coin can be accurately determined without the need for complicated electrical filters. In one embodiment, a sensor having a core, preferably ferrite, which is curved, such as in a U-shape or in the shape of a section of a torus, and defining a gap, is provided with a wire winding for excitation and/or detection. The sensor can be used for simultaneously obtaining data relating to two or more parameters of a coin or other object, such as size and conductivity of the object. Two or more frequencies can be used to sense core and/or cladding properties. Objects recognized as acceptable coins, using the sensor data, are diverted by a controllable deflecting door, to tubes for delivery to acceptable coin bins.

Patent CA-2298262-C (CA)

Granted: 2006-01-31
Abstract: The invention relates to the knowledge of sugar alcohols as indicators of biochemical maturity of pine zygotic and somatic embryos. It has been discovered that loblolly pine zygotic embryos have a progression of different sugar alcohols as they approach biochemical maturity. Pinitol is the first sugar alcohol to appear in abundance. This is followed by D-chiro-inositol, and finally by fagopyritol B1. As a later appearing alcohol becomes more abundant in the embryos, the earlier ones decrease in amount present. Analysis of the embryo sugar alcohols can be helpful in determining when to harvest cones from seed orchards. Further it can be used as a guideline for formulation of more effective culture media in the propagation of somatic embryos by tissue culture. There appears to be a requirement for fagopyritol B1 if good germination of somatic embryos is to be achieved.

Abstract: Selon l'invention, un panneau de particules, un panneau de fibres ou un panneau OSB (panneau de particules orientées) (25) est réalisé à partir d'un matériau cellulosique auquel on a ajouté un liant durcissable par rayonnement. A cet effet, on forme une couche de diffusion (4) qui subit un compression finale dans un dispositif de pressage (16), le cas échéant après une précompression dans une presse préliminaire (5), puis cette couche (4) est durcie brutalement au moyen d'un dispositif de bombardement électronique (22). A la différence du procédé de production connu, au moyen d'un liant thermodurcissable, le procédé de l'invention n'est pas entravé par le transport de chaleur jusqu'au centre des panneaux ni par un profil d'humidité non homogène. Le risque d'éclatement des panneaux est évité de sorte qu'il est possible de produire des panneaux avec un rendement et une qualité élevés. Les panneaux ne nécessitent aucun stockage de conditionnement, à la différence des procédés de production connus au moyen d'un liant thermodurcissable.

Granted: 2003-09-23
Abstract: A dynamic flow adapter to be used in measuring the rate at which air flows into the brake pipe of a locomotive. The flow adapter includes a housing, a dynamic flow valve and a differential transducer. The housing defines an input passage, an input chamber, a primary passage, a supplemental passage, an output chamber, a secondary passage and an output passage. The primary passage contains a primary orifice having a first diameter. The secondary passage contains a secondary orifice having a second diameter. The input passage communicates with the input chamber, and the input and output chambers communicate through the primary orifice. The output chamber communicates with the output passage through the secondary orifice. The supplemental passage is in parallel with the primary passage and when opened allows further communication between the input and output chambers. The dynamic flow valve is disposed within the supplemental passage. When the rate at which air flows from the input passage into the input chamber is less than or equal to a predetermined amount, the dynamic flow valve closes the supplemental passage. When the flow rate into the input chamber is greater than the predetermined amount, the dynamic flow valve opens the supplemental passage to an extent determined, up to a fully open position, by the magnitude of the flow rate. This allows air to flow through the supplemental passage, in addition that flowing through the primary passage. The transducer generates a signal proportional to the difference in pressure between input and output chambers.

Granted: 2005-03-22
Abstract: An apparatus and a method for preventing a user from bypassing a viewer blocking system that uses program related information, such as content ratings, included in a program signal. The present invention prevents the user from exploiting the time delay associated with detecting, decoding and comparing the program related information by switching channels to observe portions of objectionable programs before the blocking system can react. The present apparatus comprises a processor (110) which provides an output signal (RGB OUT) derived from a selected program signal (VIDEO, VIDEO IN, AUDIO IN) of a selected signal channel and prevents or allows user access to the output signal in response to a determination of whether a user selected program blocking criteria is met. The processor modifies the output of a selected program signal upon user selection of a new signal channel if a default blocking mode is selected by the user, then continues to modify the program signal associated with the newly selected signal channel at least until the program related information is determined.

Title: High efficiency gear pump for pumping highly viscous fluids
Inventor: WRISLEY ROBERT E
IPC: F04C13/00
Filed: 1999-09-17
Granted: 2007-07-10
Abstract: A gear pump exhibiting improved efficiency over a broader range of fluid viscosity and pump speed includes a compression zone defined between each of a pair of pump gears and internal walls of a gear chamber, wherein the compression zones have a non-uniform thickness along a longitudinal direction of the gears. The geometry of the compression zones provides a mechanism whereby the drag of the viscous fluid which is induced by the rotation of the pump gears carries the viscous fluid through a progressively narrower gap in the direction of rotation ending in a final smooth pinch-off at the start of the seal zone. The geometry of the compression zone maximizes the drag and pressurization of the viscous fluid being pumped into the teeth of the gears, thereby assisting in the complete filling of the teeth.  The result is improved fill efficiency over a broader range of pump speeds and over a broader range of fluid viscosity.
