4720291 Aero-hydraulic pollution control system
New Patents
measuring the pressure drop which occurs between two sides of an orifice plate attached to a filter bag. The apparatus includes a chamber with an orifice plate at one end and a pair of tubular pressure taps located on either side of the orifice plate whereby one tap is located on the upstream side of the orifice plate and the other is located at the downstream side. Both taps have a particular location and configuration to avoid clogging whenever the bags are cleaned. The apparatus is used in a sequentially timed and controlled system for measuring and recording bag performance of many bags in a baghouse. The system is formed by attaching the above apparatus to a plurality of bags in a baghouse and connecting the pressure taps from each apparatus to a sequentially activated and controlled valve system which individually measures the pressure drop at each bag through the use of a single differential pressure-measuring device. The controlled valve system also allows purge gas to pass through the taps while isolating the pressure-measuring device from the taps through which the purged gas is passing. The system also includes a baghouse temperature sensor, a baghouse pressure drop measuring device and a recording device so that individual bag flow and fabric drag can be calculated and recorded.

feature of the invention assists to cool exhaust gases and enables a heat recovery from the working liquid. The invention can be used for a dual purpose as an air pollution control and as an element of a technological process, where pollutant soluble in a liquid creates a new product.
4721596 METHOD FOR NET DECREASE OF HAZARDOUS RADIOACTIVEI NUCLEAR WASTE MATERIALS Richard Marriott, Frank S Henyey, Adolf Hochstim assigned to Perm Inc A method for decreasing the amount of hazardous radioactive reactor waste materials by separation from the waste of materials having long-term risk potential and exposing the~e materials to a thermal neutron flux. The utilization of thermal neutrons enhances the natural decay rates of the hazardous materials while the separation for recycling of the hazardous materials prevents further transmutation Of stable and short-lived nuclides.
4720291 AERO-HYDRAULIC POLLUTION CONTROL SYSTEM Ilya London A self-contained wet type pumpless gas pollution control and sludge-handling system, applicable for dusts, vapors, aerosols, mists and fumes, comprises the open-to-the-atmosphere liquid pollutant extractor (17) hydraulically interconnected with the gas pollutant extractor (28). The system makes use of the aerodynamic force of the exhaust fan to circulate a waterfall contaminant capture system and accumulate floats in the extractor (17) available for removal at any time. The unique concept of the open and easily accessible liquid pollutant extractor provides various types of the hydraulically automated floats removal at any time, avoiding a drainage of the system, i.e. preventing a water pollution. The diffusion control feature originates an operating liquid level, prevents and supresses fire, and provides a static pressure feedback control to stabilize a desired amount of the gas flow in spite of unexpected fluctuations of the flow resistance in the exhaust system.

4721947 WELDING
MONITOR
Kenneth W Brown, Cambridge, United Kingdom assigned to The Welding Institute A welding monitor for use with a welding system is described. The monitor comprises a store (74) for storing at least two sets of predetermined aCceptable ranges for one or more welding parameters such as voltage and current. A comparator bank (66,67) is provided for each parameter to compare the operating value of each parameter in use with the corresponding stored range or ranges. A display including sets of light emitting diodes (18-20) displays information relating to the stored ranges and operatir~g values and is responsive to the comparator banks (66, 67) to indicate the relationship between an operating value of at least one of the parameters and the corresponding predetermined range.
