Patent number: 7601184Abstract: The invention relates to a method for producing candles comprised of a starting material that contains, at least in part, fats and/or oils. Optional additives such as colorants are admixed to the starting material, and the starting material, in a liquid phase, is sprayed onto a cooling medium (10) whereby being transformed into a solid phase and, during a pressing process, is subsequently pressed to form a pressed article and is optionally milled. According to the invention, the starting material solely contains oils and/or fats that are hardened and, on the cooling medium (10), are transformed into an essentially homogenous, crystalline, preferably granular crystalline structure.Type: GrantFiled: February 21, 2003Date of Patent: October 13, 2009Inventor: Dieter Tischendorf

Patent number: 7553433Abstract: Provided is an aerosol method, and accompanying apparatus, for preparing powdered products of a variety of materials involving the use of an ultrasonic aerosol generator (106) including a plurality of ultrasonic transducers (120) underlying and ultrasonically energizing a reservoir of liquid feed (102) which forms droplets of the aerosol. Carrier gas (104) is delivered to different portions of the reservoir by a plurality of gas delivery ports (136) delivering gas from a gas delivery system. The aerosol is pyrolyzed to form particles, which are then cooled and collected. The invention also provides powders made by the method and devices made using the powders.Type: GrantFiled: February 19, 2007Date of Patent: June 30, 2009Assignee: Cabot CorporationInventors: Mark J. Hampden-Smith, Toivo T. Kodas, Quint H. Powell, Daniel J. Skamser, James Caruso, Clive D. Chandler

Publication number: 20090148929Abstract: A biostimulation agent in the form of hollow spheres comprising soy wax or a combination of soy wax and beeswax. The biostimulation agent is capable of providing sufficient nutrients to help maximize biostimulation of indigenous microbes capable of biodegradation of chemical and/or petrochemical spills in the environment. The hollow spheres can be applied by spraying the loose product onto a spill. Alternatively, the hollow spheres are contained within a porous cylinder, bag, or boom that allows a spilled chemical and/or petrochemical to permeate through and contact the spheres.Type: ApplicationFiled: October 19, 2006Publication date: June 11, 2009Applicant: UNIREM, INC.Inventors: Raymond J. Tarasi, Gary W. Dalrymple
