Abstract: An apparatus and method for the thermal and photolytic production of oxygen. Chlorine from acid and chlorine storage vessel (10) and liquid water are conveyed to heat exchange apparatus (05) for preheating. The gaseous chlorine and water are then further heated in reformer cell (25) by means of both thermal and photolytic energy, where they react to produce hydrogen chloride and oxygen, with equilibrium amounts of steam and chlorine. The aforementioned hydrogen chloride, oxygen, steam and chlorine are then cooled in heat exchange apparatus (05), where the condensed water acts to solvate the hydrogen chloride to dilute hydrochloric acid. Gaseous oxygen and chlorine are vented and conveyed to gas clean-up unit (100). Another embodiment of this invention is a method for the joint i) abatement of emission of a "greenhouse" gas by removing carbon dioxide from an effluent and ii) manufacture of methanol by reaction of hydrogen with carbon dioxide.

Abstract: A rotary self-cleaning servicing system (50; 200) services inkjet printheads (34; 36) in an inkjet printing mechanism (20). A rotary service station (200) has a wiper supporting tumbler (202) that rotates about an axis (55) parallel to the printhead scanning direction (41) to wipe the printhead (34; 36) orthogonally along the length of a linear nozzle array (354; 355).

Title: Locking pin apparatus
Inventor: ROBINSON HOWARD W
IPC: E02F9/28
Filed: 1995-10-18
Granted: 2004-07-13
Abstract: A locking pin for use captively retaining a tooth on an adaptor portion of an excavating tooth and adapter assembly has a primary wedge member with an integral spring extending upward from the member's distal end. A first positive stop means extends from the wedge member while an opposing second positive stop means extends from the integral spring. After insertion, the locking pin prevents separation of tooth from adapter portion while the first and second positive stop means prevent accidental loss of the locking pin from the assembly. To remove the locking pin, a force sufficient to separate the first positive stop means from the pin is exerted to drive the pin from the assembly. In another embodiment, the integral spring extends from a lateral surface of the locking pin. In another embodiment, the locking pin comprises stop means which are radially extendable by spring means. In another embodiment a non-integral spring is attached to the locking pin and allows for the use of a different material for the spring.

Abstract: An improved highly automated method and system for providing individual animal Electronic Identification, measurement and value based management of cattle in a large cattle feedlot. Through the use of (1) a computer system integrated with (2) electronic or other automatic individual animal identification (3) multiple measurement and remeasurement systems with automatic data input means and (4) a cattle handling and sorting system, animals are individually (a) identified and (b) measured by weight, external dimensions and characteristics of internal body tissue. With this information together with physiological characteristics and historical data on the animals, the computer system calculates the optimum (c) slaughter weight, (d) economic end point and (e) marketing date for shipment to a packing plant. After measurement, individual animals are (f) sorted by direction of the computer in response to calculations from the measurements. The computer system also calculates from the individual animal data and other data (g) each animal's pro rata share of the actual feed intake for the group with which it is being fed. The computer system (h) stores individual animal measurement, performance and location data, which is used by management to (i) select animals for shipment from the feedlot for slaughter at the optimum time. Following an animal's shipment to a slaughter facility, its identification in the computer system is used to (j) correlate the live animal physical characteristics and performance data to the measured and evaluated carcass characteristics data obtained during the slaughter process and (k) build a data base to more accurately identify and measure value based characteristics in subsequent animals produced and fed for more effective value based selection and management of those animals.

Granted: 2007-10-09
Abstract: Procédé et système de récupération d'énergie à partir de combustibles secondaires tels que les déchets agricoles, municipaux et industriels, les combustibles houilleux secondaires tels que le lignite, ainsi que des combustibles solides analogues. Selon ce procédé, le combustible est broyé en petites particules et mis en suspension épaisse avec de l'eau. La teneur en alcalis de la suspension est ajustée de façon à être plus ou moins égale à l'équivalent chimique de la teneur en halogène de la suspension. Suite à sa mise sous pression, la suspension est chauffé à un niveau suffisant pour qu'une partie substantielle de l'oxygène à liaison chimique présent dasn le combustible se séapre de ce dernier sous forme de dioxyde de carbone, laissant ainsi une suspension comprenant des particules de charbon et des impuretés dissoutes telles que des sels d'halogène. Les particules de charbon sont enlevées de la suspension et remises en suspension avec une quantité d'eau dépourvue d'halogène tout juste suffisante pour conférer la viscosité requise à la suspension afin d'en optimaliser la densité d'énergie. Les particules de charbon sont ensuite mises en réaction avec l'air à une température inférieure à leur température d'inflammation afin de convertir le pouvoir calorifique du combustible secondaire en énergie thermique qui est alors utilisée notamment pour entraîner une turbine (253, 255, 257).
