Abstract: An  induction  heating  furnace   (10)   is disclosed comprising an induction coil assembly (16) and a ladle (12)  having a metallic shell  (14) that supports a crucible holding metal to be heated by the furnace.  The ladle (12) is readily separated from the induction coil assembly (10) so that the heated metal may  be  conveniently  and  reliably  moved  among operational stations.  The induction coil assembly (10) has a preselected length which is less than the length of the shell (14).  The induction coil assembly (10) surrounds, but does not touch the  shell  (14)  and generates an electromagnetic induction  field.   The induction coil assembly (10)  comprises a coil  (20), upper and lower yokes (28 and 34) and an intermediate yoke (40) coextensive with the coil (20). The upper and lower yokes (28 and 34) are separated from each other and electromagnetically coupled together by the intermediate  yoke  (40).     The  upper,  lower  and intermediate  yokes  (28,  34  and  40)  each  comprise stacked laminates  (72  and 74)  formed of sheets of ferrous material.

Granted: 1998-11-10
Abstract: A dual pulse flashlamp-pumped laser system (50) having a power supply circuit (62) which not only charges two capacitors (C1, C2) which are successively discharged to produce  two  laser pulses,  but also  supplies a simmer current through the flashlamp (58) between the pulses.  The first laser pulse follows a trigger pulse on a flashlamp trigger wire (60) which ionizes the flashlamp gas, permitting a first capacitor (C1) to discharge through the flashlamp (58).  The simmer current maintains the flashlamp gas in an ionized state, so that a second trigger pulse is not needed.  The second laser pulse follows an SCR-controlled discharge of the second capacitor (C2) through the flashlamp (58).

Granted: 1998-12-01
Abstract: 2131292 9321042 PCTABS00027 An inflator comprising: a pressure vessel (10) for storing a quantity of stored inflation gas under pressure. The pressure vessel comprising a first burst disk (46) and a seal disk (310) both for selectively sealing same. The inflator (10) including a gas release mechanism (52, 300) for permitting the controlled, staged release of the inflation gas at determinable inflation rates. The gas release mechanism includes: a first pyrotechnic device, positioned outside of the pressure vessel and spaced from the first burst disk (46), including a piston (72) moved into a disk piercing position to rupture the first burst disk (46) in response to the buildup of pressure caused burning of a first quantity of propellant material (218). The bursting of the first burst disk permits the inflation gas to initially flow out of the pressure vessel at a determinable cold inflation rate, the piston thereafter provides a conduit to communicate the products of combustion of the burning propellent to the pressure means so as to increase the temperature of the inflation gas therein and thereby increase the rate of egress of the gas. The inflator (10) also includes a second pyrotechnic mechanism (300), positioned outside of the pressure vessel and spaced from the seal disk (310), for providing, when activated, additional products of combustion arising from burning of a second quantity of propellent material, the products of combustion opening the seal disk (310) and thereafter entering the pressure vessel to heat the inflation gas therein and thereby elevate the rate of egress of the inflation gas above the rate achievable by the first pyrotechnic device.

Title: Circular saw leveling and tensioning machine
Inventor: BROWN ERNEST W
IPC: B23D63/18
Filed: 1995-01-18
Granted: 2005-07-26
Abstract: A circular saw blade straightening and tensioning machine has a set of straightening and tensioning rollers on both sides of a saw blade. The rollers are mounted on parallel shafts. Each shaft has a hub at its end, comprising a center portion horizontally eccentric with respect to the center line of the shaft, and a pair of side portions disposed on opposite sides of the center portion. Each of the side portions is horizontally eccentric with respect to the shaft center line, but in a direction opposite to that of the center portion. A roller is rotatably mounted on each of the center and side portions of the hubs. An actuator rotates each of the upper and lower shafts selectively ninety degrees in both the clockwise and counterclockwise directions. Rotation of the shafts selectively force a center roller against one surface of the saw blade while simultaneously forcing the side rollers against the other surface of the saw blade, thereby to level deformations in the blade. Rotation of the shafts in opposite directions forces the center rollers on both shafts against both surfaces of the saw blade, thereby to tension the blade. A sensor includes a movable foot pivotably mounted intermediate four fixed foot supports. The movable foot carries a gauge that measures the deviation underneath the movable foot from the plane determined by the fixed supports.

Patent CA-2156007-C (CA)
Inventor: LEBING WYTOLD R
IPC: C07K14/81
Filed: 1995-08-14
Granted: 2010-03-09
Abstract: Cation chromatography with solutions at pH less than 6.0 and low ionic strength can be utilized to purify human .alpha.-1. proteinase inhibitor (.alpha.-1 PI) from biological fluids including plasma and plasma fractions. The cation chromatography takes advantage of the fact that active .alpha.-1 PI does not bind to the cation column under these conditions but other proteins, including denatured .alpha.-1 PI and albumin, do. The effect is that active .alpha.-1 PI flows through the chromatography column leaving the contaminating proteins behind. Recovery of .alpha.-1 PI is high and improvement of purity is dramatic.

Title: Apparatus and method for feeding print media from a stack
Inventor: MARZULLO JOSEPH H
IPC: B65H1/02
Filed: 1995-11-24
Granted: 2005-11-08
Abstract: The sheet feeder includes a tray having a pusher mechanism mounted at a rear portion and a feeder mechanism mounted at a forward portion. The pusher mechanism is driven through a spring wrap clutch which includes a ratchet which engages a pawl mounted on the feeder mechanism. When the feeder mechanism is in a first position the pawl is disengaged from the ratchet and the clutch is free to rotate and engage the pusher mechanism which advances the stack of sheets against the feeder mechanism, driving the feeder mechanism back to a second position where the pawl engages the ratchet, disengaging the spring wrap clutch and halting the pusher mechanism. As sheets are fed from the stack a spring urges the feeder mechanism back towards the first position, disengaging the ratchet and engaging the clutch and repeating the cycle. A spring maintains a substantially constant normal force between the feeder mechanism and the stack as the feeder mechanism moves between the first and second positions.

Granted: 2003-05-06
Abstract: A safety circuit for monitoring computer hardware that can create an unsafe condition if a failure occurs. The circuit includes a microprocessor, a keyword decoder, and a dynamic safety relay drive circuit.  The microprocessor runs a set of internal tests which c reate a keyword made up of a series of bits. A particular series of bits indicates  the desired operation of the microprocessor. On alterna te generations of the keyword one bit in the series is inverted. The keyword de coder receives the keywords and outputs a "true" signal if the keyword indicates the desired operation of the microprocessor, and "fals e" signal if the keyword indicates otherwise. The output  of the keyword decoder is transmitted to the dynamic safety relay drive circuit , and this signal will keep the circuit energized as lon g as its alternating. The position of the bit which is inverted is rotated through th e keyword so that different bit paths through the keywor d decoder may be tested.
