A punch is installed eccentrically at front end of the cylindrical portion of the punch holder, which is then firmly fixed by means of the crescent-formed seat or split-half hollow cylindrical seat and the clamping block to the inside hole which is furnished at the front end of the ram.

A device for feeding wire stock of fixed length to a cutoff tool in a linear and continuous manner by means of the reciprocating motion of a wire cutting mechanism driven by an eccentric shaft being utilized to sever and sequentially feed the cutoff wire stock one at a time to a die head.

A nut forming machine of the conventional cold nut forming type employing a frame body mounting a crank shaft; a power source and belt drive means; a ram carrying first, second, third stage punches and a piercing punch; respective cooperating die sets; punch out means; rocking means; stock feeding and blank cutter means; transfer clamp means; and a cut off base mounting a slide block for actuating the blank cutter wherein (1) the ram is connected at its laterally opposed ends by respective crank...

The disclosed invention relates to a feeding device for a rotary die head of an automatic highspeed cold heading machine adapted for forming bolts, machine screws, rivets, and like products and, more particularly, to an intermittent rotary motion mechanism consisting principally of one or two pairs of cam gears and an epicyclic train of gears for transmitting an intermittent rotary motion to the rotary die head of the heading machine.

A knockout mechanism for a high-speed automatic cold heading machine having first and second eccentric shafts. A driving link is mounted on the first eccentric shaft by an antifriction bearing. A rocker arm is pivotally connected to the driving link at a location spaced from the connection of the link to the first shaft. The rocker arm is connected to the second shaft so that the rocker arm continuously oscillates. Knockout means including an ejecting rod are actuated by the rocker arm to eject ...

A feeding device for high speed nut formers and more particularly a feeding device whereby blanks are fed along a guide way in a series of short linear transfer operations and are positioned in front of die stations in sequence by means of a transfer mechanism capable of transferring said blanks linearly along a straight guide way and returning along an arcuate path.

A feedstock cutting and feeding device for forming machines having a reciprocating cutter which will cut the feedstock in one, short stroke and hold the cut feedstock in a position to be easily introduced to a transfer disc by the advancement of the feedstock.

A magnetic deflector for a magnetic ink jet printer has compensating pole pieces which alter the gradient field produced by deflection pole pieces so as to counterbalance centering forces acting on magnetic ink drops moving through the magnetic field in off center locations. The compensating pole pieces are preferably passive and extend from the zero potential region of the magnetic circuit of the deflection pole pieces.

An automatic high-speed cold heading machine which forms heads on wire blanks by means of punch, cutting, and ejector mechanisms, where the operations of the punch and the ejector mechanisms are performed simultaneously and, wherein, the punch, the cutting knife and the ejector mechanisms are driven simultaneously in continuous harmonic motion with no pause or dwell for the purpose of achieving stable high speed operation.

This invention provides a process for clarifying and concentrating Xanthomonas heteropolysaccharide fermentation broth, which process includes filtration and ultrafiltration steps. A clarified and concentrated xanthan gum solution of the present invention contains between about 8-15 weight percent xanthan gum, and exhibits a viscosity in the range of 15,000-30,000 centipoises, and a light transmittance of greater than 5 percent as measured by a colorimeter.
