Granted: 1999-05-04
Abstract: A posing station for a portrait studio which allows for great flexibility in the taking of subjects' portraits. The posing station can be converted between a seating area with an aisle behind it for group photographs and an expansive surface for baby and small children photographs. The posing station is linked to a frame which supports the rest of the portrait studio equipment including the lighting, camera and backdrops. This results in all the critical distances between the studio equipment remaining fixed. The studio can also be automated so that the photographer need a minimum of effort while producing expert quality photographs.
Patent CA-2081974-C (CA)

Abstract: An improved control of a motor vehicle torque converter clutch (TCC) which detects a condition of TCC engagement when open converter operation is required, and activates an override mechanism to disengage the TCC independent of the normal TCC control in response to the detected condition.  This ensures that the TCC is disengaged when open converter operation is required, thereby permitting continued operation of the vehicle in conditions where the vehicle would otherwise be inoperable.  When unwanted TCC engagement is detected, the control activates a clutch priority valve by intentionally commanding the engagement of two or more range clutches.  When so activated, the clutch priority valve exhausts all but one range clutch and hydraulically disables engagement the TCC. When the vehicle speed is sufficiently high to permit TCC engagement, all but one of the range clutch pressure commands are eliminated, and the clutch priority valve returns to a normal state to permit TCC engagement.

Granted: 1999-04-06
Abstract: A process for preparing pillared chromium ribbon-like silicate clay .alpha.-olefin catalysts is disclosed. This process utilizes palygorskite and sepiolite clays. The pillaring of said clays comprise the steps of: (a) preparing a hydrolyzed first solution by dissolving a chromium salt and a base in water, heating said first solution to a temperature in the range of about 20°C to about 100°C while stirring continuously until the solution reaches a pH in the range of about 1.5 to about 2.5 and thereby producing a master batch; (b) diluting said master batch with water to produce a diluted second solution and heating said diluted second solution to produce a heated second solution; (c) adding a solid clay selected from the group consisting of sepiolites and palygorskites to said heated second solution, and continuing heating; (d) recovering said pillared chain silicate clay; (e) drying said pillared chain silicate clay to form first product. The activation of said clays comprise the steps of: (a) heating said first product at a temperature in the range of about 150°C to about 500°C and for a time period in the range of about 30 minutes to about 10 hours in an inert atmosphere; (b) thereafter reheating said first product at a temperature in the range of about 500°C to about 900°C and for a time period in the range of about 1 hour to about 50 hours in an oxidizing atmosphere and recovering said catalyst composition. This results in clay catalysts which polymerize .alpha.-olefins.

Abstract: Hot raw fuel gas is produced by the partial oxidation of liquid or gaseous hydrocarbonaceous fuel or an aqueous slurry of solid carbonaceous fuel with substantially pure oxygen. The raw fuel gas is cleaned, cooled in a plurality of indirect heat exchangers, and purified to produce clean sulfur-free fuel gas.     Water is the coolant in one of said indirect heat exchangers and is thereby heated. Dry nitrogen gas is humidified with the warm water and the humidified nitrogen gas is separately introduced into the combustor of a combustion turbine. The clean sulfur-free fuel gas is passed in indirect heat exchange with the raw fuel gas, expanded to reduce its temperature and pressure, and separately introduced into the combustor where it is burned with air while in the presence of the water humidified nitrogen gas. Flue gas containing water humidified nitrogen gas and a substantially reduced amount of NO x gases is produced and passed through a power-producing expansion turbine as the working fluid. Increased power and efficiency are thereby obtained without polluting the atmosphere.

Abstract: A powered bread slicer capable of slicing successive loaves of bread to selected different slice thicknesses.  A rotating circular bread slicing knife is mounted on a pivotal, reciprocal arm for shifting the knife from a retracted position through slicing positions between and transverse to an infeed table and an outfeed table, and return to the retracted position.  The slice thickness is selected, as for standard one-half inch thickness, deli one-quarter to three-eighths inch thickness, garlic or French bread up to one inch thickness, or otherwise.  A variable stepper motor incrementally advances a loaf pusher one step at a time, the dimension of the step being of the selected slice thickness dimension.  The distance by the travelled loaf pusher to reach the end of its travel is monitored to determine whether the bread heal is thick enough to slice once more.  This decision is a function of the selected slice thickness dimension.  A detector sensing the leading end of the loaf initially activates the slicer knife drive and the support arm drive.  A pusher detector adjacent the knife prevents knife advancement with presence of the pusher adjacent the knife, allowing the pusher to move past the knife to push the fully sliced loaf completely onto the discharge table, and then return to the infeed table.

Abstract: An improvement to the chloride process of making titanium dioxide. By recycling some of the cyclone dust, the yield in the chlorination of titanium-containing raw materials can be increased. In order to prevent silica accumulation in the fluidized bed, the cyclone dust is divided into two fractions. An economic solution is described of a single-stage separation of the cyclone dust in a hydrocyclone, the majority of the titanium dioxide occurring in the hydrocyclone underflow, although the separation is not sharp. By grinding the dried solids from the hydrocyclone underflow, the titanium dioxide particles returned to the lower region of the fluidized-bed reactor are rapidly chlorinated, while the quartz and coke particles are rapidly discharged again from the fluid bed, so that no silica contamination occurs.
