Patent NO-158351-C (NO)
Inventor: GRECSEK JOHN JEROME
IPC: C11D7/00
Filed: 1982-02-25
Abstract: Free flowing spray dried beads which are useful as a detergent or for the manufacture of a particulate built synthetic nonionic organic detergent composition include water softening aluminosilicate (such as a zeolite), bentonite and water soluble builder, and may also include water soluble synthetic organic detergent and a small proportion of water soluble silicate, although such silicate is preferably omitted. The beads can be made to be of a bulk density within a broad range, and the bulk density may be varied by control of the bead formula and by modification of spray drying conditions. The base beads and detergent compositions formulated with them are of reduced aluminosilicate deposition characteristics, due to the presence of bentonite and the absence of or presence of only a low content of water soluble silicate, with the bead composition being maintained within given ranges. The moisture content of the beads will be such as to maintain at least 2% and preferably 3% or 4% or more of moisture in the bentonite so that its normal swelling power is retained, because the swelling of the bentonite is considered to be important in dispersing the beads in wash water and also, even more importantly, in helping to prevent aluminosilicate agglomeration and objectionable deposition thereof on materials washed, and in helping to break up any minor proportion of such agglomerates which might be formed.

Title: Method and apparatus for optimizing fuel-to-air ratio in the combustible gas supply of a radiant burner
Inventor: CLARK DANIEL REED
IPC: F23N5/08
Filed: 1991-05-30
Granted: 2001-08-28
Abstract: A method and apparatus to optimize the proportion of gaseous fuel and air supplied to a radiant burner employed in a heating appliance. With the flow rate of the gaseous fuel supply held constant, the flow rate of the air supply is adjusted to change the relative proportion of air and fuel in the mixture to attain an optimum value far burner combustion, i.e. a vague where the proportion of air is slightly greater than the stoichiometric ratio. The invention employs a sensor to measure the intensity of the radiation emitted by the burner while the the air supply to the burner is varied. From the measurements obtained, control parameters are derived which are then applied to set the air supply flow rate to a level that results in the optimum proportion of air and fuel in the mixture.

Inventor: SALAMI BAHMAN
IPC: B03B9/06
Filed: 1993-09-01
Granted: 1998-04-14
Abstract: Waste material, consisting of collected nickel-cadmium or nickel-hydride cells, after a preliminary reduction in size (1), is subjected to a subsequent grinding reduction in size (2) and is then screened.  The screen coarse fraction (G) is separated into a light fraction (L) and a heavy fraction (H) by means of an air separation (4), and the later fraction (H) is magnetically separated.  The light fraction (L) and the non-magnetic portion (HN) are dried (6) and screened (7) in order to free the non-metallic components (P,PPW) from the predominantly metallic fine portion (S) and so that they can be divided out as a harmless product.  The magnetic portion (HM) is mechanically scoured (8) and possibly washed (9), whereby one obtains a smeltable Ni-Fe mixture.  The screen fine fraction (F) and the fine portion (S) resulting from the processing of the coarse fraction (G) axe dissolved in thinned acid (HCL).  After filtering (21) the acid at least metallic nickel and as the case may be cadmium or metal hydride are selectively extracted from the purified solution (22).  The acid after being cleaned of waste electrolyte (KOH) can be recycled.

Title: Continuous process for expanding thermoplastic minipellets
Inventor: HALL THOMAS N III
IPC: C08J9/18
Filed: 1993-09-28
Granted: 1998-02-03
Abstract: The subject invention pertains to a continuous process for expanding thermoplastic minipellets, particularly polypropylene.  The minipellets are continuously expanded by continuously charging and mixing water and minipellets in a slurry tank to form a slurry which is subsequently pressurized.   A blowing agent such as butane is entrained into the pressurized slurry flow, which said slurry is then heated by a heating means, such as a shell and tube heat exchanger, to the softening point of the minipellets.  The heated minipellets are given the time necessary for impregnation by permitting them to flow through one or more impregnation vessels.  The impregnated minipellets are released through an orifice into an expansion vessel where the blowing agent flashes off, thereby expanding the minipellets.
