Title: An apparatus and method for emulsifying a pressurized multi-component liquid
Inventor: GIPSON LAMAR HEATH
IPC: B29C48/14
Filed: 1996-12-04
Granted: 2005-02-08
Abstract: An apparatus and a method for emulsifying a pressurized multi-component liquid by applying ultrasonic energy to a portion of the pressurized multi- component liquid as it is received in a chamber and passed through an orifice. The apparatus (100) includes a die housing (102) which defines a chamber (104) adapted to receive a pressurized multi-component liquid and a means for applying ultrasonic energy (116) to a portion of the pressurized liquid. The die housing (102) further includes an inlet (110) adapted to supply the chamber with the pressurized multi- component liquid, and an exit orifice (112) defined by.the walls of a die tip (136). T he exit orifice (112) is adapted to emulsify a pressurized multi-component liquid when the means for applying ultrasonic energy is excited with ultrasonic energy while the exit orifice (112) receives pressurized multi-component liquid from the chamber and passe s the liquid out of the die housing (102). When the means for applying ultrasonic energy (116) is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip (136). The method involves supplying a pressurized multi-component liquid to the foregoing apparatus (100), applying ultrasonic energy to the pressurized liquid but not the die tip (136)while the exit orifice (112) receives pressurized liquid from the chamber (104), and passing the pressurized liqui d out of the exit orifice (112) in the die tip (136) so that the multi-component liquid is emulsified.

Patent CA-2248721-C (CA)
Title: A computer system and process for defining and manufacturing images using structured objects with variable edge characteristics
Inventor: KIVOLOWITZ PERRY S
IPC: G06T15/00
Filed: 1997-03-05
Granted: 2005-12-20
Abstract: An image representation using a structured object may be readily manipulated by a computer. This image representation can represent more complex images where the structured object defines a boundary for which image values near the boundary in a region are defined by a function called an edge characteristic function. The edge characteristic function is applied by determining, for each point in the region, a point on the boundary to which the given point is closest, herein called an anchor, and a distance to that point. Different edge characteristic functions may be assigned to different points along the boundary. In one embodiment, edge characteristic functions are assigned to selected for characteristic points on the boundary. These edge characteristic functions may be interpolated to provide edge characteristic functions for remaining points along the boundary. Each point not on the boundary is processed according to the edge characteristic function of the point on the boundary to which it is closest and according to the distance to that point. An edge characteristic function may also be a function of other factors. This image representation provides many benefits including the ability to generate more complex images which can then be manipulated more easily or be converted from different image formats. One form of manipulation is interpolation over time. In image compositing, this image representation also allows for easy attenuation of various effects over regions in a controlled way.

Granted: 2008-10-14
Abstract: The invention relates to a process and a device for producing silicon-rich foundry pig iron. The process comprises the following steps:   a) silicon oxides and iron-carbon metals are introduced into a DC furnace as the charge;   b) the charge is maintained under a highly reductive atmosphere;   c) the column of material is guided annularly at least in the vicinity of the vessel base; and d) is exposed to the radiant heat from a heat source which is situated in the free area in the region where the annular column of material opens out above the furnace base.     The DC furnace, with an electrode which is arranged centrally, projects into the furnace vessel and is guided as far as the vicinity of the base, and a counterelectrode which is arranged in the base of the furnace vessel, is one in which the electrode projecting into the vessel is surrounded by a coaxially guided sleeve, the ratio between the external diameter (d) of the sleeve and the internal diameter (D) of the furnace vessel being d:D = 1:4 and the opening of the sleeve being spaced apart from the furnace-vessel base at a distance (a), where 2 x d <=- a <= 4 x d.

Title: Apparatus and methods for cleaning delicate parts
Inventor: PUSKAS WILLIAM L
IPC: B08B3/12
Filed: 1997-08-01
Granted: 2008-02-05
Abstract: Clamped ultrasonic transducers are driven at harmonic resonant frequencies in a range of 100 kHz - 350 kHz to impart microsonic frequencies to process liquid. The application of microsonic frequencies to liquid preferably occurs simultaneously with a sweeping of the microsonic frequency within the transducer's (122) harmonic bandwidth to reduce or eliminate (a) standing waves within the liquid, (b) other resonances, (c) high energy cavitation implosion, and (d) non-uniform sound fields, each of which is undesirable for cleaning and/or processing of semiconductor wafers and other delicate parts. The invention can also drive ultrasonic transducers (122) such that the frequency of applied energy has a sweep rate within the ultrasonic bandwidth of the transducers; and that sweep rate is also varied so that the sweep rate is substantially non-constant during operation. An ultrasound generator of the invention sometimes utilizes amplitude modulation (AM), and the AM frequency is swept over time so as to reduce resonances. Two or more transducers are sometimes used by the invention, in combination, to broaden the overall bandwidth of acoustical energy applied to the liquid around the primary frequency or one of the harmonics. The bandwidths of the transducers are made to overlap such that an attached generator can drive the transducers, in combination, to deliver ultrasound to the liquid in a broader bandwidth.
