Abstract: An inlet orifice device to control thruput flow for a pressure regulator, and to prevent increases in inlet pressure from causing variations in outlet pressure. The novel inlet orifice device also permits improved relief valve performance by limiting the maximum available thruput flow to constant levels, within the design range of inlet pressure, regardless of the variation of the inlet pressure supplied within such range.The improved inlet orifice device serves the dual function of controlling the thruput flow by (1) varying the open area (flow limiter area) on the inlet side of the pressure regulator thru the said device and (2) cooperating with the valve to vary the open area (throttling area) on the outlet side of the said device. The improved inlet orifice device includes a fixed nozzle on the inlet side and a control member moveable relative the nozzle and the valve, which valve is disposed on the outlet side and actuated responsive the diaphragm.

Abstract: A latch needle is disclosed with a sliding bolt of unique construction which is easily manufacturable and which serves with particular effectiveness in accordance with this invention in carrying out blindstitch sewing.

Abstract: A child's sewing machine having a frame including a work-supporting bed, a vertical standard projecting upwardly therefrom adjacent one end of said bed, a hollow bracket arm extending horizontally from said standard longitudinally above the bed and terminating in a sewing head, said bracket arm having a through aperture formed therein adapted to accommodate a veriical spool pin providing rotatable support for a thread supply for a thread carrying needle, said frame further carrying stitch sewing instrumentalities including a thread carrying needle. An adapter plate is secured to the bracket arm and has provision for a horizontal spool pin thereon and an upstanding thread guide.

Abstract: A barometrically compensated pressure index continuous integrator assembly for measuring the throughput fluid flow of a meter comprising a pressure sensing means mounted within a chamber and adapted to expand or contract in a straight line responsive to changes in the pressure of the fluid flow. The chamber or pressure sensing means communicates with the fluid flow of the meter to communicate line pressure therefrom and the other is evacuated to substantially zero absolute pressure. A link transfer assembly interconnects the pressure sensing means with a pressure index continuous integrator for regulating the output thereof in accordance with variations in the absolute pressure being measured.

Abstract: Apparatus and method of making a very dense tufted fabric using a programmed intermittent backing fabric feed in combination with means for changing the relative lateral displacement of the point of needle penetration into the backing fabric. The method in general comprises feeding a backing fabric through the machine, tufting stitches into the backing, stopping the fabric feed and initiating relative lateral displacement between the backing fabric and the needles, tufting additional stitches into the backing fabric and either initiating further relative displacement between the backing fabric and the needles and tufting again or feeding the fabric forward and repeating the process.
