Abstract:
A burner for use in furnaces such as in steam cracking. The burner includes a primary air chamber; a burner tube having an upstream end, a downstream end and a venturi intermediate said upstream and downstream ends, said venturi including a throat portion having substantially constant internal cross-sectional dimensions such that the ratio of the length to maximum internal cross-sectional dimension of said throat portion is at least 3; a burner tip mounted on the downstream end of said burner tube adjacent a first opening in the furnace, so that combustion of the fuel takes place downstream of said burner tip; and a fuel orifice located adjacent the upstream end of said burner tube, for introducing fuel into said burner tube.
Abstract:
Chemically and yeast leavened bakery products which have improved shelf lives are provided by the inclusion of an effective amount of a starch or flour selected from a plant of a wxsu.sub.2 genotype in the bakery product dough. Breads which contain the starch or flour, preferably obtained from maize, are provided with a softer, moister crumb after baking as well as a fresher texture and appearance after a storage period.
Abstract:
An improved burner and a method for combusting fuel in burners used in furnaces such as those found in steam cracking. The burner includes a burner tube having a downstream end and an upstream end for receiving fuel and air, flue gas or mixtures thereof, a fuel orifice located adjacent the upstream end of the burner tube, for introducing fuel into the burner tube, a burner tip mounted on the downstream end of the burner tube and adjacent a first opening in the furnace, the burner tip having a plurality of air flow notches positioned about an outer periphery thereof, a peripheral tile surrounding the outer periphery of the burner tip, forming the first opening in the furnace, and a burner tip seal in contact with at least a portion of the outer periphery of the burner tip and the peripheral tile, wherein a plurality of air gaps is formed between an inner periphery of the burner tip seal and the air flow notches, the plurality of air gaps effective for providing a portion of the air for combustion.
Abstract:
A pump having a symmetric end cap is disclosed. The end cap is attachable in a first position or a second position wherein the second position is rotated relative to the housing. A trunnion arm extends in a first direction and a system port opens in a first orientation when the housing is connected to the end cap in a first position. The end cap includes structure such that the housing may be connected in a second position so that the trunnion arm extends in a second direction while maintaining the system port opening in the first orientation. The end cap may be provided with a symmetric porting system. A control device for affecting movement of the swashplate is disclosed. Methods of locking the swash plate into a predetermined position are also taught.

Abstract:
A pump unit having a pump cylinder block mounted in a housing on an end cap. The cylinder block is driven by a pump input shaft, where the input shaft has a first driven end and a second end, and the second end extends through the end cap and out of the housing.
Abstract:
A device for controlling a hydraulic pump having a swash plate controlled by a trunnion arm, including a control arm attached to the trunnion arm. The pump is mounted in a housing that may include a symmetric end cap. A stud is mounted in the pump housing and extends parallel to the trunnion arm. A control structure is attached to the stud engages and controls the control arm.
