Patent CA-1340767-C (CA)
Inventor: STELTENKAMP ROBERT JOHN
IPC: C11D1/52
Filed: 1987-08-07
Granted: 1999-09-28
Abstract: N-lower alkyl neoalkanamides of 1 to 4 carbon atoms in the lower alkyl thereof, and of 5 to 14 carbon atoms in the noealkanoyl group, e.g., N-methyl- and N-ethyl neodecanamides, are new compounds which have insect repellent properties, being especially effective against cockroaches, e.g., the German cockroach. However, they are also useful as repellents for other insects, including, for example, American cockroaches, mosquitoes, flies, fleas, ants, and lice. The most effective of the described amides for insect repellency are normally liquid and are sufficiently volatile to be detectable in air by insects. They may be applied directly to surfaces to be treated or they may be incorporated in detergent compositions, such as laundry detergents, floor and wall cleaners, rug cleaners and shampoos, hair shampoos, and liquid and bar soaps, and have been found to be sufficiently substantive to the substrate being washed so as to impart insect repelling properties to it. The invented N-lower alkyl neoalkanamides have been found to be of long lasting effectiveness, with significant and measurable insect repellency being obtainable for as long as two weeks after application. They are stable during normal trees, relatively low in manufacturing cost, of high substantivities to substrates, economical to use, unobjectionable in odor to humans, and safe to humans and animals, and to the environment. In addition to insect repelling uses, the invented N-lower alkyl neoalkanamides are also useful components of perfumes. Various products, such as detergent compositions, shampoos, waxes and polishes, pet care items, insect repellents and insecticides, may be perfumed with the invented perfumes, which results in such products and compositions being made insect repellent so that surfaces to which they have been applied also become insect repellent, as well as perfumed.

Abstract: A  process  for  preparing  a  stable pourable shortening   having  a  pumpable  consistency  that  is retained  at  ambient  temperatures  after  storage for extended  periods  over  a  temperature  range of about 0°F   to   about   100°F  and  the  resulting  product. Solid    fatty   glyceride    particles   capable   of crystallizing  in  the beta phase are mixed with liquid glyceride   oil.    The  particle  size  of  the  solid particles  is reduced while dispersed in the liquid oil until   substantially  all  of the  particles  have  a maximum  particle  size  of  about  70  microns.    The temperature   of   the  mixture  is  increased  as  the particle  sizes of the solid particles are reduced such that  the temperature does not exceed the melting point of  the  solid  fatty  glyceride particles and at least 10%  of  the  solid fatty glyceride particles remain in the  solid  phase.    The  mixture is cooled to ambient temperature  to  form a pourable shortening having from about  2  to  about 18% by weight total solid particles with  at  least  90% of the particles having a particle size  less than about 45 microns and at least about 80% of  the  particles  having a  particle  size less than about  30 microns.  The pourable shortening can be used for  frying  and pastry baking, and incorporation of an emulsifier  provides an all-purpose pourable shortening that is particularly adapted for baking cakes.

Granted: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE    A full-open end closure (27) with edge-protection for a peripherally-located scoreline (34) which defines the disc (31) to be removed.  A back-scoreline (132) located within the removable disc co-acts with a longitudinally rigid (non-lanced) opener (30), made integral by a rivet (32) formed from sheet metal of such disc.  A multilayer fold (40) of sheet metal in the removable disc shields the raw edge of ruptured residual peripheral scoreline metal which remains with such disc.  The back scoreline central portion (160) is contiguous to and radially inward of such rivet and, a pair of legs (163, 164) extend on opposite sides of the rivet toward the adjacent portion of the peripheral scoreline such that rupture of the back scoreline legs tends to move the opener in a radial direction of   the end wall closure.   Such radially-directed movement of the opener is controlled, and the working end of the opener is turned inwardly, in relation to a container at a prescribed location with respect to the peripheral scoreline so as to facilitate ease of initial rupture.  The remainder of the peripheral score-line is severed by continuing arcuate movement of the handle end of the opener which placed the handle end radially outboard of the container for lever action opening using the chime seam (170) as a fulcrum.
