Title: Method of avoiding decreased-size first drops when aspirating from immersed rest conditions
Inventor: FOOTE ANDREW SHELLEY
IPC: B01L3/02
Filed: 1996-04-25
Abstract: A method for avoiding a reduction in volume of the first drop dispensed by a pump from a dispensing tip stored immersed within the liquid to be dispensed.  The method comprises the steps of:  a) while the tip is still immersed in the liquid, dispensing enough air from the tip into the liquid to create an air bubble which, when the tip is withdrawn from the liquid, will break apart, b) withdrawing the tip from the reservoir to cause the bubble to separate therefrom, optionally producing a skin of liquid across the tip orifice, c) aspirating the optional skin and a small amount of air into the tip at least two times, d) ejecting more volume of air than was aspirated in step c), leaving at most only traces of liquid in the tip, e) adjusting the pump so as to position it at about the center point of its dispense/aspirate cycle, f) immersing the tip back into the reservoir of liquid, g) aspirating an amount of the liquid from the reservoir into the tip, and dispensing the aspirated amount back into the reservoir, the amount being enough to substantially clean out the traces of liquid, and h) thereafter, aspirating the preselected amount of liquid for subsequent dispensing.

Abstract: A synthetic reinforcement (22) having a plurality of micro-recesses (58) on at least one surface (54) to facilitate adhesion to at least one wood structural member (10) and a process for making the same is disclosed. The synthetic reinforcement (22) is comprised of a plurality of continuous fibers (46) that are maintained in position by a resin encasement (50). The surface (54) of the synthetic reinforcement (22) is characterized by micro-recesses (58) that are located in a generally random pattern, which increases the surface area of the resin encasement. The micro-recesses are formed by way of the addition of an agent such as a solid particulate, liquid or a multiplicity of gas-filled spheroids into the raw resin and then abrading away the agent in the surface of the cured resin. The synthetic reinforcement (22) is connectable to a wood laminae (10) or to another synthetic reinforcement with commercial grade adhesives such as the resorcinol resins, which are suitable for adhering the wood laminae together.

Inventor: LAGREE JAMES LEO
IPC: H02H1/00
Filed: 1996-10-02
Abstract: A two-source medium voltage electric power distribution system has main circuit breakers in each main bus connected to one of the sources and a tie circuit breaker in a tie bus connecting the main buses. Overcurrent trip units in the main circuit breakers, have one current transformer (CT) sensing current in the associated main bus and a second CT sensing current in the tie bus. The CTs are connected to sum their sensed currents in opposition so that with the tie circuit breaker closed the overcurrent trip unit on the faulted side of the system will see the sum of the fault currents from the two sources and trip the associated main circuit breaker open. The overcurrent trip unit of the main circuit breaker on the opposite side of the system from the fault will have the same current flowing in the oppositely poled CTs and will not trip, while the tie circuit breaker will see the fault current from the source on the opposite side of the system from the fault and will trip. Zone interlock signals from the overcurrent trip units of feeder circuit breakers are applied to the tie-circuit breaker trip unit and the trip unit of only the main circuit breaker on the same side of the system as the fault to allow time for the feeder circuit beaker to respond to faults in the feeder circuits with out blocking the other main circuit breaker from tripping in response to a simultaneous main bus fault on the opposite main bus.

Abstract: An unscrambler for unscrambling a bundle of elongated tubes comprises a plurality of forward belt-support columns, a plurality of aft support columns, a plurality of flexible belts suspended in parallel between the forward and aft support columns forming a belt magazine for retaining the bundle of tubing which extend longitudinally in a direction perpendicular to the belts, and a plurality of ramps positioned longitudinally between each pair of adjacent belts sloping upwardly towards the forward support columns and positioned such that they provide support for the bundle in the belt magazine. The ramps each have a wedge extending from their upper surfaces, and each wedge has a forward face which intersects the upper surface of the ramp to form a v-shaped groove on the ramp. Furthermore, each of the belts have a cleat attached to their upper surfaces.  Tightening of the belts causes the bundle to be guided up the ramps and lifted above the wedges on the ramps such that the bundle expands outwardly. Subsequent slackening of the belts causes the expanded bundle to be lowered onto the wedges such that the wedges separate a portion of the tubes from the bundle and such that the v-shaped grooves retain the separated portion of tubes on the ramps.  Tightening of the belts again causes the cleats to engage and convey the separated tubes from the ramps to a magazine ramp adjacent the forward support column.

Inventor: PALMER ANTHONY JAMES
IPC: B41J17/04
Filed: 1997-05-08
Abstract: A thermal printer for printing on a continuous print medium by ink transfer from a thermal print ribbon has a print head which is pivotally mounted and which is driven in an oscillatory nodding motion by means of a stepper motor so as repeatedly to bring a linear array of energisable printing elements to bear against a platen roller. Both the element array and the platen extend transversely to respective paths of travel of the print medium and the ribbon. The print medium is fed through the printer from an inlet region, between the platen and print head, and thence to an outlet region. The instantaneous rate of travel of the print medium past the print head is substantially the same as the rate of feed of print medium to the printer. Typically this rate is of the order of 250 to 400 mm per second. The ribbon also travels between the print head and the platen, overlying the print medium and is driven in such a manner that it travels at the same rate as the print medium during each printing operation up to a speed equivalent to the maximum printing speed of the print head. This is achieved by driving the ribbon with a motor the speed of which is controlled according to the sensed speed of travel of the print medium, e.g. by coupling the motor to processing circuitry which takes an input signal from a shaft encoder associated with the platen roller. These methods of driving the ribbon have the advantage that the ribbon speed can be varied to take account of different print medium speeds, e.g. due to the requirements of differing packaging processes, and also in response to transient variations in print medium speed during each printing operation. To restore the aspect ratio of characters when the print medium is travelling faster than the speed equivalent to the maximum speed of the print head, lines of dots are skipped.
