Abstract: A mass spectrometer is disclosed comprising an ion trap wherein ions which have been temporally separated according to their mass to charge ratio or ion mobility enter the ion trap. Once at least some of the ions have entered the ion trap, a plurality of ion trapping regions are created along the length of the ion trap in order to fractionate the ions. Alternatively, the ions may be received within one or more axial trapping regions which are translated along the ion trap with a velocity which is progressively reduced to zero.

Abstract: A mass spectrometer is disclosed wherein the experimentally determined mass to charge ratios of ions are reported together with an error band for each mass to charge ratio determination. The error band may, for example, reflect a 95% probability or confidence that the real, true, actual or accepted mass to charge ratio of the ion lies within the error band. By accurately determining the error band the possible candidate ions in a database can be accurately restricted whilst also guarding against over restriction.

Abstract: A memory includes byte aligned column redundancy capabilities for use in repairing the memory when a defective column is present. The memory array includes a repair/redundant column for use in repairing the memory when another column of the memory array is defective. The memory also has a redundant write multiplexer to select, when a defective column is present in the memory array, an input data bit to be written to the redundant column. A first input of the redundant write multiplexer may be coupled to receive either the LSB or the MSB of write data associated with the first column group and a second input of the redundant write multiplexer may be coupled to receive either the LSB or the MSB of write data associated with the second column group.

Abstract: Protein surfactants are recovered from processed menhaden fish. Stick water is clarified and soluble proteins contained therein are precipitated by the addition of ammonium sulfate. The precipitated proteins are recovered from the solution.

Abstract: Shaping of automatic audio crossfade is accomplished by adding a shaping function to the theoretical logarithmic crossfade function to decrease the rate of gain change at the limit of audibility. The gain change at each sample time within a crossfade interval is computed as a logarithmic function of the fractional part of the crossfade interval completed and the gain differential between the sources. The shaping function may be in the form of a cosine function that can be accessed with a look-up table that is added to the fractional part of the crossfade interval so that the gain change is expressed by:ti G.sub.delta =20*log{(k-s(k))*10.sup.(G.sbsp.1.sup.-G.sbsp.2.sup.)/10 }where S(k) is the shaping function, k is the fractional part complete and G.sub.1 -G.sub.2 is the gain differential between sources. The gain change is added to the current gain for the particular audio source and applied to a variable gain element for that source.

Abstract: A coach seat locking mechanism is disclosed which is compatible for use with existing revolving type coach seats. A metallic body having a vertical bore is affixed to one end of the seat lower frame and a locking rod is vertically reciprocal within the bore between an upper, locking position and a lower, unlocked position. A pedal arm having a cam is pivotally affixed to the body and is designed for foot operation form an upper, locking position to a lower, unlocked position. Upon depressing the pedal arm, the locking rod is lowered to its unlocked position and simultaneously, the pedal cam contacts a body affixed extraction arm to transversely move the seat upper frame away from the coach sidewall. A detent is pivotally secured to the body to maintain the pedal arm in its unlocked position.

Abstract: User selection of meter ballistics is accomplished by separating the meter display from the meter drive circuitry. An input signal is input in parallel into appropriate level determining circuits, with the outputs being selected for processing by a microprocessor. The microprocessor processes the selected outputs according to a ballistic standard selected by an operator to generate a display signal. For LED displays the display signal has a bar component that illuminates all the LEDs up to the maximum level of the displayed output and a dot signal that illuminates only one or a very few LEDs around the maximum level of the displayed output.

Abstract: An audio mixer architecture using virtual gain and switching has a single gain stag in each audio input signal path. A plurality of audio input signals are input to respective audio input channels having two or more active gain elements at the output to provide parallel signal paths for each audio input signal. The audio signals from the active gain elements are combined to form up to four audio output channels in any desired combination of audio input signals. The individual audio input signal gains and the master audio output signal gains are synthesized together as a single gain control signal for each active gain element to simulate successive gain stages for each audio input signal path within a single gain stage for that path.

Abstract: Flexible bag dispensers for plastic bags such as those used to carry merchandise purchased in grocery stores or hardware stores. The dispensers are generally "w"-shaped to form two cells in order to dispense two sets of bags. The frame is formed by a back portion which connects three or more side portions which support the bags. Flexion members such as spring-loaded hinges may be mounted to and connect members in the back portion, one or more side portions, or at intersections between one or more side portions and the back portion to allow the side portions to flex when a person or object impacts the dispenser.

A metallic body having a vertical bore is affixed to one end of the seat lower frame and a locking rod is vertically reciprocal within the bore between an upper, locking postion and a lower, unlocked postion. A pedal arm having a cam is pivotally affixed to the body and is designed for foot operation form an upper, locking position to a lower, unlocked position. Upon depressing the pedal arm, the locking rod is lowered to its unlocked position and simultaneouly, the pedal cam contacts a body affixed extraction arm to transversely move the seat upper frame away from the coach sidewall.

Abstract: Dispensers for storing flexible bags and holding such bags open at an appropriate height while they are being filled with items. The dispensers include a bag container or holder means such as a spool or hook which may be adjustably mounted vertically and laterally to the dispenser frame. A suspending means corresponding to the bag container means holds the handle of the bag not held by the container means and may accommodate an extender to allow the bag handle to be held adjustably in height. Such a dispenser may also be formed to be adjustable in width to accommodate larger bags and spread them appropriately for optimal wall separation. Novel C-shaped brackets may be used to receive wire rungs on the dispenser frame to allow the dispenser to be manually removed and remounted with a single swift motion at various heights to a counter, wall or other surface.
