摘要： The present invention relates to an improved cryogenic process for the separation of air to produce an oxygen product and a nitrogen product. The present invention employs a distillation column system with three distillation columns, a low pressure column, a medium pressure column and a high pressure column. The improved three column distillation system process comprises: (a) producing an oxygen product with a product purity of less than 98% purity oxygen and producing no argon product; (b) producing a gaseous nitrogen product which represents greater than 35% of the feed air and which is removed from the medium and/or high pressure columns; (c) recovering a major portion of the oxygen product from the low pressure column; and (d) condensing at least a portion of the high pressure nitrogen overhead from the high pressure column by heat exchange against a liquid stream in the medium pressure column and utilizing at least a portion of the condensed portion to provide reflux to the high pressure column.

摘要： A circuit and corresponding method for doubling the frequency of an input signal, even when the input signal is of low frequency or a square wave. The input signal is applied to a phase-shifting circuit that produces a pair of output signals that are theoretically 90° apart in phase, but may lack the desired form if the original input signal is of low frequency. The waveforms of the two output signals are enhanced in latching hysteresis buffers that produce more uniformly squared waves, with zero crossings corrected to be more exactly 90° apart and with desirably steep state transitions. The enhanced-waveform output signals are coupled to an exclusive OR (XOR) gate to produce a double-frequency output.

摘要： A mattress support table with conveyor receives a mattress from a feed conveyor. The support table then indexes to a central position whereat a sewing machine passes around the periphery to sew the uppermost fabric panel to the border panel. The table then indexes to the exit conveyor and discharges the sewn mattress to be turned over, whereupon the mattress is returned to the support table to sew a bottom fabric panel. The table conveyor may be moved with a sewing machine so that an edge of the mattress is presented to the table periphery thereby allowing the sewing machine access to the edge.

摘要： Upholstery tufting apparatus comprises an insertion needle (5) with an aperture (4) to receive a tuft for insertion into an article to be upholstered. The tuft is presented to the needle aperture (4) along a tuft feed axis (3). The apparatus has a plurality of tuft strings (2a, 2b, 2c), a first string (2a) with tufts of a first length and a second string (2b) with tufts of different second length. The apparatus has one or more tuft feed units, and an actuator operatively connected to said tuft feed unit(s). The first and second tuft strings (2a, 2b) are associated with the tuft feed unit(s). A selected one of the tuft feed unit(s) is actuatable by the actuator to align one of the first and second strings (2a, 2b) with the tuft feed axis (3) according to the length of tuft required to be inserted into an article to be upholstered. A method for tufting an upholstered article employing said apparatus is also described.

摘要： A circuit for supplying selected currents to a charge pump without harmful effects arising from operation of current switches in the charge pump. A charge pump current setting is applied in digital form to a set of two-position switches coupled to binary-weighted current sources. Currents from the sources selected by the switches are combined, and the total current is mirrored to the charge pump. Simultaneously, those of the binary-weighted current sources not selected by the switches to contribute to the charge pump current are separately combined, and this total current is mirrored to an electrical replica of the charge pump. Thus the currents supplied to the charge pump and to the replica charge pump are complementary in the sense that they always add to a constant total current drawn from a common power supply. Therefore, abrupt changes in current load are avoided and switching noise effects are minimized.
