Abstract: A B S T R A C T.   An apparatus for ventilation, recovery of heat, dehumidification and cooling of air or industrial gases for use in industrial processes and in airconditioning of residential, commercial and industrial buildings compri-ses a highly effective valveless periodic flow type dehumidifier-heat ex-changer in which a countercurrent flow of two gaseous streams through a sta-tionary matrix of  a heat and moisture exchanging material is  achie-ved by an air fan controlled by a variable timer controller. The stationa-ry matrix may include a single bed or two beds of solid materials with dis-tinguished moisture and heat sorption properties, a heater and a wet filter to provided simultaneously an effective transfer of heat and moisture, re-moval of particulates and adiabatic cooling of the two gaseous streams. The released sorption heat is temporarily stored within the matrix material and then used in reactivation of the matrix. If required, additional heat may be conveniently provided by a fossil fuel, electric, solar or waste heat energy sources. Small amount of power is used in opera-tion of the air fan that may also provide ventilation of the air conditio-ned building.                T I T L E   O F   I N V E N T I O N .

Title: Method of applying energy, carbon skeleton and nutrient materials to vegetation
Inventor: YAMASHITA THOMAS T
IPC: C05F11/00
Filed: 1989-09-06
Granted: 1995-10-10
Abstract: Composition for and method of stimulating growth of plants,  e.g.  increase  in  crop  production.    The composition  comprises  a  carbon  skeleton/energy component, typically a sugar or mixture of sugars; a macronutrient  component  providing  the  elements nitrogen,  phosphorus,  potassium  and  calcium, preferably also magnesium and sulfur; a micronutrient component  providing  zinc,  iron  and  manganese, preferably also copper, boron, molybdenum and cobalt. The  composition  also  preferably  contains  a vitamin/cofactor  component  and  an  enhancement component.  The composition may be in the form of an aqueous solution or in a form suitable for coating seeds or coating pollen.   It may be applied as a foliar spray, as a soil amendment, as a root dip or as an injectable solution.   Preferably where,  for example, it is used as a foliar spray it is applied at intervals at different stages of growth.            The  method  is  useful  for treating vegetation  to promotes plant growth and/or crop production,  also for  treating  pollen,  seeds,  roots  and  soil  and inhibiting growth of insects and micro-organisms.  A formulation  including  an  energy/carbon  skeleton component,  a macro nutrient component and a micro nutrient  component  is applied,  e.g.  in  aqueous solution by foliar spraying.   This is done in a manner to make optimum use of the inherent ability of vegetation to harvest solar energy and to utilize other sources of energy and carbon skeleton, such that the energy and nutrients applied by the method of the invention is a fraction of the energy and carbon skeleton requirements of the vegetation.

Abstract: A considerable portion of the gas developed by fermentation in an anaerobic purification equipment for waste water, together with buoyant sludge, is collected by at least one additional collecting system (5), before it may reach the upper part of the reactor. This additional collecting system is fitted at a distance below the collecting system (6) fitted as usual just below the level of one or more overflow gutters (3; 23) for purified water. The additional collecting system (5) has a hydraulic link with one or more rising pipes (7, 7', 27, 32,31) for raising the liquid sludge mixture by gas lift action. The rising pipes discharge into a separation device (8) from which one or more downpipes (9; 29) for returning separated liquid and sludge extend to the lower section of the reactor chamber. As a result of the tranquility at the top and the turbulence near the bottom, a substantial increase of the load capacity of the equipment can be obtained.

Date May 16, 1991.A process and apparatus for monitoring and ensuring safe operation of unvented kerosene heaters in indoor spaces detects the hazard of incomplete combustion and the concomitant reduced O2 and increased CO2 levels in the indoor air. CO2 level in the indoor air is monitored quickly and accurately, - regardless of the burner's flame height. This is achieved by sensing O2 level in the burner exhaust which is used as a measure for monitoring the CO2 level in the indoor air and as a control signal. During burner operation outside a predetermined flame height range, the O2 detection is used both for restoring a normal heating condition and for monitoring operation at minimum flame height and to generate a warning signal and a delayed automatic shut-down of the burner.
