Abstract: A constant air pressure unit for an air handling system. The unit comprises a housing having an air inlet opening for admitting pressurized air into the housing. The housing has a top wall with a by-pass opening therein and a door is displaceably retained over the by-pass opening. The door has a predetermined load whereby the door is caused to lift away from the by-pass opening when the pressure of the air in the housing is equal to the pressure required to lift the load. The door load defines a maximum housing pressure. In the case where the pressure at the inlet opening starts to increase above the predetermined maximum housing pressure, the door lifts and by-passes the excess pressurized air and thus limits the inlet and housing pressures. In a corollary unit, an air outlet opening for releasing air is included. A pressurized airflow path is defined between the inlet opening and the outlet opening. The outlet airflow is restricted by the use of an adjustable restrictor blade which will start to increase the pressure in the housing. With the door load selected for a desired inlet pressure, the excess pressurized air is then evacuated through the by-pass opening so as to maintain a substantially constant air pressure at the inlet and thus a substantially constant inlet airflow volume rate with a variable outlet airflow volume rate.

Abstract: In accordance with the process of the invention, bacteria are used to provide hydrogen sulfide and carbonate compounds for treating solutions containing metal ions. To produce the hydrogen sulfide, the bacteria utilize sulfate ions present in the solution. Hydrogen sulfide produced by the bacteria is used to remove metals from the solution as insoluble metal sulfides. The process of the invention thereby removes sulfate and metal ions from the treated solution. The bacteria used are mixed populations, including strains of naturally-occurring sulfate reducing bacteria, which have been serially adapted and selected to be highly active with the particular solutions to be treated and with the carbon and hydrogen sources being utilized. The bacteria may be fed gaseous hydrogen and carbon nutrients produced by a partial oxidation burner. Carbonate compounds produced by the bacteria may be used to raise the solution pH for treatment and discharge. By controlling the addition of hydrogen sulfide and carbonate compounds to the solution, the preferential isolation of particular metal sulfide concentrates may be accomplished in separate precipitation steps, each with a specific pH and sulfide dosage.

Abstract: Heavy crude oil containing at least 1% by weight water is hydrotreated and upgraded while being produced downhole in a production well. During production the heavy crude oil containing water is subjected to sonic energy at a low frequency of 400 Hz to 10 kHz downhole in the presence of a metal hydrogenation catalyst that causes the water in the crude oil to react and form hydrogen which then hydrotreats and upgrades the heavy crude oil during production. In another embodiment, if the heavy crude oil does not contain water, the hydrogen may be formed in-situ by contacting the heavy crude oil downhole with a chemical compound comprising ammonia, hydrazine and formic acid that in the presence of a metal hydrogenation catalyst and sonic energy causes the chemical compound to react and form hydrogen which then hydrotreats the heavy crude oil during production. Suitable catalysts include nickel on zinc dust, platinum on carbon and palladium on carbon, preferably nickel on zinc dust. The hydrotreated and upgraded heavy crude oil has improved properties making it easier to refine and transport by pipeline. The upgrading includes reducing the amount of asphaltenes and resins in the heavy crude oil and increasing the amount of aromatics and saturates.

Title: Apparatus for trimming folded printed products, such as newspapers, periodicals, brochures and the like
Inventor: MEIER JACQUES
IPC: B26D11/00
Filed: 1996-07-11
Granted: 2006-11-07
Abstract: An apparatus for trimming printed prorducts.      The apparatus includes a drum with a plurality of radially displaced receiving compartments. The printed products which are to be trimmed rest, along their folded edges, against stops which form the base of the radial receiving compartments. The products are gripped by a displacement device and displaced radially outwards into a cutting position. In the cutting position, the printed products are clamped in the region of their side border located opposite the fold edge. When the clamped printed products run past a stationary cutter element, the printed products are trimmed on the side border. After completion of the cutting operation, the clamping of the printed products is released and the displacement device is moved by a further distance radially outwards. Consequently, the trimmed printed products are advanced into a removal position, in which they are gripped by grippers of a removal conveyor. The controlled advancement of the printed products both into the cutting position and into the removal position ensures that the printed products can be trimmed and received by the grippers of the removal conveyor in precisely defined positions along the printed products.
