Abstract: A process and apparatus for preparing a multi-compartment container having two open ends and a partition wall that forms a fluid-tight seal defining two compartments each holding a separate component to be mixed with one another by the end-user prior to use. The process and apparatus for filling the two-compartment container comprises filling one compartment with material through an opening at one end of the container; sealing the opening; rotating the container; filling the other compartment with material through an opening at the other end of the container; and sealing the other opening preferably with a removable seal.

Abstract: This invention relates to a system and method of detecting any compromise to the seal separating the compartments in two-compartment flexible packages. Such seal tamper indicating system may include a middle seal area configured to form an interface compartment between the two main compartments, the interface compartment providing a visual indicator of whether a seal has been compromised. In another embodiment, a flow valve device may be connected between two compartments, the normally closed position of the valve providing the sealing between the two compartments until the contents of the two compartments are ready to be mixed.

Abstract: A container holding two separate components which are mixed prior to use is provided. The container comprises a housing with a dispensing opening and neck portion between said opening and the bottom end of housing. The container further comprises a displaceable member disposed within the housing and having a partition wall with an edge adapted for a sealing engagement with internal walls of the neck portion, thereby defining two compartments separated by said partition wall. A displaceable member is axially displaceable between two positions along an axis extending through the neck portion. These two positions comprise a first position where the edge of the partition wall sealingly engages the internal walls of the neck portion, and a second position where the edge of the partition wall and the internal walls are disengaged permitting flow communication between the two compartments. This flow communication allows mixing of the two components to form a formulation which is then ready for use.

Abstract: A container holding two separate components, which are mixed prior to use is provided. The container comprises a housing defining a first compartment having a sealable opening and a neck portion between said first compartment and said opening. The container further comprises a displaceable member which is disposed within the housing which has a partition wall with an edge adapted for sealing engagement with the internal wall of the neck portion, thereby defining a second compartment sealed from the first compartment and being in flow communication with the opening. The displaceable member is axially displaceable between two positions along an axis extending through the neck portion. These two positions comprise a first position where the edge of the partition wall sealably engages the internal walls of the neck portion, and a second position where the edge of the partition wall and the internal walls of the neck portion are disengaged, permitting flow communication between the two compartments.

Abstract: A container for storing two components separately and then mixing them prior to use includes a housing having an opening and a neck portion, a displaceable member, and a closure member. The housing is formed with a first compartment and a second compartment intercommunicating at the neck portion. The displaceable member has a partition wall for sealing the neck portion. The displaceable member is formed such that the partition wall moves from a non-sealing position in which the first and second compartments intercommunicate to a sealing position in which the neck portion is sealed. The displaceable member also may feature at least one conduit for allowing introduction of a component through the opening into the housing. The closure member seals the at least one conduit of the displaceable member and/or the opening of the housing. The displaceable member may be moved by rotating, pushing or pulling and may be moveable by a portion exterior to the housing.

Abstract: A disk certifier which analyzes a read signal generated from a disk of a hard disk drive. The read signal typically has a sinusoidal waveform with modulated peak amplitudes. The waveform is generally defined by the equation A.multidot.sin(wt).multidot.(1-m(t)), where the term m(t) is the amplitude modulation of the signal. The peak signal is provided to a phase lock loop circuit which generates a multiplier peak signal generally of the form sin(wt). The certifier includes a multiplier which multiplies the read signal by the multiplier read signal to provide a multiplied read signal described by the equation A/2.multidot.(1-cos 2(wt)).multidot.(1-m(t)). The multiplied read signal is filtered by a low pass filter which has a cut-off frequency Wc below w. The low pass filter provides a filtered multiplied read signal which is described by the equation A.multidot.(1-g(t)), wherein the term g(t) is the portion of m(t) with frequencies below Wc.

Abstract: The present invention relates to a method and apparatus for the measurement of defects in magnetic recording disks using a logarithmic amplifier. A magnetic head senses a magnetic field of a magnetic disk and creates a read signal having a varying amplitude. The test apparatus has a squarer which receives and squares the read signal. A logarithmic amplifier coupled to the squarer converts the squared signal to a logarithmic signal. The logarithmic signal is filtered by a first filter. A second filter coupled to the logarithmic amplifier provides an average of the peaks of the logarithmic signal. A digital-to-analog converter coupled to the second filter scales the output of the second filter. The test apparatus further comprises a comparator having a first input and a second input, where the first input is coupled to the first filter, and the second input is coupled to the digital-to-analog converter.

Abstract: An apparatus and method for demodulating an amplitude modulated read signal generated by a magnetic head of a hard disk drive. The apparatus includes a pair of serially connected track and hold circuits that receive the read signal. The track or hold state of each circuit is controlled by a phase lock loop circuit which also receives the read signal. The first track and hold circuit initially tracks the read signal to a peak value. The circuit then switches to a hold state and provides a constant output signal that corresponds to the peak voltage of the read signal. While the first track and hold circuit is in the hold state, the second track and hold circuit is in a tracking state. The second track and hold circuit tracks the output of the first circuit. Because the output of the first circuit is a constant value, the second circuit also provides a constant output signal in the tracking state.

Abstract: A tester for measuring the resistance of magnetoresistive heads as a function of the magnetic field applied to the heads. The tester applies a time varying magnetic field to the magnetoresistive head to be tested and filters the resulting time varying (AC) voltage signal indicative of the resistance of the head with a capacitor to remove the DC component of the signal. The AC component of the signal is then amplified, digitized, and analyzed to obtain the resistance properties of the magnetoresistive head.
