Abstract: Abstract of the Disclosure Herein disclosed is a process for producing a steel bar or  steel  wire,  comprising  the  steps  of  heating  a steel containing less than 2 % of C at a temperature higher than the Ac1 point of the steel, rough working the heated steel, finish working the rough-worked steel within a temperature range between Ar1 and Ar3 or Arcm with a reduction ratio of at least 20 % and subjecting the finish-worked steel to an annealing treatment, whereby providing a steel bar or steel wire having an improved spheroidal structure of cementite.    The  cooling  rate  of  the  rough-rolled  steel  to  the starting  temperature  of  the  finish  rolling  should  be controlled in the following manner:    When the hardenability of the steel is not higher than that of 0.15% C plain carbon steel, it is preferable to cool the  rough-worked  steel  at  a  cooling  rate  higher  than 250°C/sec.    When the hardenability of the steel is between   those of 0.15% to 0.4 % C plain carbon steel, it is preferable to cool the rough-worked steel at a cooling rate higher than 10°C/sec.    When the hardenability of the steel is not lower than that of 0.4% C plain carbon steel, it is preferable to cool the  rough-worked  steel  at  a cooling  rate  higher  than 2°C/sec.    The  annealing  may  be  conducted  by  an  isothermal treatment, slow cooling treatment, repeating treatment or a usual annealing method.

Abstract: FEEDER DEFLECTION COMPENSATION             ABSTRACT          A high-pressure transfer device, utilizable with wood chips or particulate material, includes low-pressure inlet and outlet ports, with low-pressure shoes associated therewith, and high-pressure inlet and outlet ports with high-pressure shoes associated therewith.  A rotor containing a plurality of diametrically through-going pockets operatively communicates with the ports.  The low-pressure ports, and shoes, are quadrate in cross-section, and retainers are provided surrounding the low-pressure shoes for guiding radial movement thereof.  The retainers include end portions which engage side walls of the high-pressure shoes for guiding radial movement thereof.  Biasing means bias the shoes into operative association with the rotor to maintain effective sealing between the rotor and housing, unaffected by radial deflection of the housing.  The high-pressure shoes contain through-extending openings which may be quadrate in cross-section at the portions thereof closest to the rotor, and circular in cross-section at the portions thereof furthest from the rotor.  Pressure compensators, supplied with hydraulic fluid at a pressure proportional to that at the high-pressure inlet and outlet, are operatively associated with the high-pressure shoes to maintain the bias thereof into engagement with the rotor.  The rotor, and all shoes, are made of metal.

Abstract: ABSTRACT   In apparatus for shaping sheets of heat-softenable material, such as glass and plastics, an upper vacuum mold is provided with an apertured wall member of low expansion refractory material to engage a heat-softened sheet during a portion of its shaping.  In order to improve its durability, metal clamping devices that cause high local stresses in the refractory wall member are not used to secure the refractory wall member to metal structural elements of the vacuum mold.  The present invention comprises novel mold structure to support a lower apertured wall member of refractory material on an inverted metal box member without metal attachment devices that induce high local stresses.

Abstract: DOCUMENT CONVEYING METHOD AND APPARATUS       ABSTRACT OF THE DISCLOSURE An apparatus and method are provided whereby two superposed strips (26, 28) of documents are conveyed in a direction of conveyance (30) toward a downstream workstation.  The strips (26, 28) are conveyed over one another in a direction of superposition whereby the leading edges of documents of one strip alternate in sequence in the direction of conveyance with the leading edges of documents in the other strip.  A determination and control (190) circuit is provided to determine whether the leading edges of documents in one strip are tending to creep up on the leading edges of documents in the other strip due to differing speeds of motion of the two superposed strips.  If a creeping condition is determined by the circuit (190), the circuit (190) energizes braking means (400) whereby the motion of at least one of the strips is at least temporarily retarded for rectifying the creeping condition.  The determination and control circuit (190) comprises a detector (188) for determining when leading ones of documents have been separated from their respective strips; timing pulse generation means (200); counter select means (206) for selectively enabling a first counter (202) and a second counter (204) to count timing pulses (the counters (202, 204) being enabled in alternating fashion after documents are separated in alternating strip fashion from their strips); and, comparison means (207) for comparing the counts in the two counters (202, 204). The detector (188) detects when leading edges and trailing edges of separated documents are conveyed past the detector (188).  The counters (202, 204) are enabled to count when the trailing edge of a preceding separated document is detected and are disabled when the leading edge of a just-separated document is detected.  The control circuit (190) periodically deenergizes the braking means for a time period extending from the time at which the leading edge of a just-separated document is detected until the time at which the trailing edge of the just-separated document is detected, thereby precluding uneven wear of the braking means.

During a power-up phase, the timer generates a system reset signal and counts the counters in a predetermined sequence.  A flip-flop (32) is set and reset during the power-up phase and inhibits generation of the system reset signal.  During a normal operating phase, the timer (10) generates a test signal that must be responded to by the host system to continuously inhibit generation of the system reset signal.
