Abstract: ABSTRACT A reduced calorie dairy mix for use in frozen dairy desserts and yoghurt is made from milk and/or milk products that have been treated with a lactase/beta-galactosidose enzyme which hydrolyzes lactose to glucose and galactose. This increases sweetness, reduces lactose crystallization problems and creates a greater freezing point depression. Aspartame or other high potency sweeteners may be added without the need for additional bulking agents and/or bulk sweeteners.

Abstract: A drill, which is excellent in sharpness and strength, capable of preventing burrs at an exit of a machined bore and of suppressing an excessive enlargement of the machined bore size, and is low in manufacturing costs, and easy to re-grind.     A rake face (30) is provided to improve sharpness of a single chisel edge (3) formed between the tip end of the drill and a first main cutting edge (1), and a non-chisel-edge-forming portion (B1OB2) is provided between the drill tip end and a second main cutting edge (2) to improve strength of the drill.  A margin portion (5), provided in a peripheral portion of the drill tip end at the side close to the first main cutting edge and having a non-cutting-edge-forming portion (11), is disposed in slide contact with an inner peripheral surface of a machined bore to achieve a guide shoe function, thereby improving, during drilling process, stability of an outer peripheral cutting edge (6) formed in the peripheral portion of the drill tip end at the side close to the second main cutting edge.  The outer peripheral cutting edge extends at an acute angle relative to the outer periphery of the drill as seen from the axial direction of the drill, to cause machined material to be directed to the inward of the machined bore, thereby preventing burrs.  The rake face associated with the chisel edge is comprised of a twisted curved surface whose lead is the same as those of rake faces (10) of various drill portions, making it easy to produce the drill and perform re-grinding.

IPC: F23C1/12
Filed: 1991-03-21
Abstract: An apparatus and method for reducing nitrogen oxide emissions from furnace flue gas is provided in which natural gas or other fluid fuel which has little or no fixed nitrogen is introduced into the upper portion of the furnace. The fuel diffuses by laminar or turbulent diffusion into oxygen-rich flue gas where it reacts with oxygen and nitric oxide to form CO2, H2O and N2, thus reducing the nitrogen oxide emissions from the furnace.      In this manner, the amount of nitrogen oxide in the flue gas is reduced. The apparatus and method can be easily applied to new furnaces or retrofitted on existing furnaces.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus in which a latent image is developed with marking particles. The marking particles are transported to the latent image by a donor roller. As the marking particles are being moved to the latent image, they are electrically charged by a blade in contact with the donor roller. An AC potential is applied on the blade. The AC potential is operator adjustable to change the charge on the toner particles. This corrects for changes in the environment and permits the slope of the tone reproduction curve to be optimized for the latent image being developed.
