Patent CA-2237242-A1 (CA)
Inventor: MILLER VAN
IPC: A23C9/15
Filed: 1998-05-08
Abstract: A reduced-fat dairy spread which is spreadable at refrigeration temperatures has an appearance, flavour, consistency, rheology and mouth-feel which is similar to conventional butter. The dairy spread has a formulation which comprises 20% to 55% by weight of butterfat, 30% to 75% by weight of water, 5% to 30% by weight of milk solids, and zero to trace amounts of each of a butter culture, salt, and approved butter colours which are compatible with butter, as well as zero to trace amounts of lecithin, potassium sorbate, sodium benzoate, and an acidifier. The soft but solid appearance, and refrigeration temperature spreadability, of the dairy spread is achieved as a consequence of protein coagulation at elevated temperatures of a stirred mixture of the starting materials. The liquid starting materials, heavy cream or milk, are unhomogenized; homogenization of the mixture does not occur until after protein coagulation at elevated temperatures has taken place. When the reduced-fat dairy spread is made, the water content is bound by the protein constituents of the milk solids, and is in a continuous phase dispersion. On the other hand, the butterfat is in a discontinuous phase, suspended in the continuous phase dispersion.

Title: Ignition systems
Inventor: KINGE RICHARD ARTHUR GEORGE
IPC: F02P3/08
Filed: 1998-07-20
Abstract: Conventional ignition systems have a first capacitor connected by a switch to the primary windings of a transformer. The secondary windings of the transformer are connected to an igniter via a cable. In the present invention, the secondary windings of the transformer are connected to a second capacitor via a rectifier circuit. The igniter is connected to the second capacitor by a cable that also has its own capacitance. In use, the combined charge on the second capacitor and the cable is gradually increased each time that the switch is closed and charge on the first capacitor is transferred to the transformer. The charge on the second capacitor and cable keeps increasing until it is sufficient to fire the igniter.
