Apparatus and method for supplying feedstock to a reservoir containing material having a portion which is heated to a molten condition and vaporized by an electron beam. The electron beam is supplied from a heated filament and directed to impact on the vapor source material by electric and magnetic fields. The feedstock is suspended above a portion of the reservoir out of the path of the electron beam. Skip electrons along with some secondary electrons emitted from the surface of the material in...

A feedwell comprises two parallel circular channels side by side or superimposed. In the case of side by side channels they have apertures in their floors and device is provided for adjusting the sizes of the apertures. When the channels are superimposed, the apertures face radially inwardly and also have a device for adjusting their sizes. In the case of two side by side channels downward flow below the apertures is baffled by two series of superimposed and spaced apart baffle plates of differe...

A feed mechanism for transferring workpieces from a loading station to an unloading station comprises a carrier which is arranged to grip the workpieces during their transference and a frame relative to which the carrier is horizontally movable to effect the transference. The carrier is also movable vertically relative to the frame so that it can be raised or lowered vertically into engagement with each workpiece at the loading station. A piston and cylinder assembly is operable to raise and low...

This invention relates to an improved feed for poultry comprising vegetable materials containing a specified amount of iodine, niacin, hormones and trace amounts of calcium and magnesium which result in a lower cholesterol content of laid eggs and a process for feeding such animals.

A container, having generally vertical end and sidewalls and a semi-cylindrical bottom portion, defines a discharge opening in the bottom portion that is normally closed by an underlying plate-like closure member. Toggle linkage and a closure member engaging cam operate to press the closure member against the bottom portion so as to make sealing contact between the container and the closure member. A feed mixing agitator rotates within the container and includes mixing vanes adjustably mounted o...

A high speed knitting machine and method, in which yarn is fed to the needles of the knitting machine by fluid under pressure in a feed conduit, in such a way that it is directed into the hooks of the needles tangentially to the stems of the needles.

A mixer with a substantially conical mixing chamber supported vertically with its apex lowermost. A tapered auger is situated in the mixing chamber and mixer drive is provided at the base of the mixing chamber. The narrowmost end of the tapered auger is connected to the drive such that the auger rotates around its own axis and its upper end rolls around the upper periphery of the mixing chamber. The upper end of the auger has a wheel to allow the auger to freely roll around the upper periphery o...

Apparatus for feeding corrugated blanks to processing machinery which comprises roller members mounted above a vacuum chamber which enables each advancing blank to be held flat while minimizing friction between the advancing blank and the feed bed comprised of the rollers. Improved vacuum chamber construction is utilized in which an adjustable back stop includes improved sealing means to minimize vacuum loss.

A fluid cylinder assembly includes a cylinder and a piston slidably disposed in the cylinder, the cylinder having a cylinder bore closed at both ends by end caps. One of the end caps is provided therein with a flow control valve assembly for controlling the fluid flow from the cylinder bore during a working stroke of the fluid cylinder assembly. The flow control valve assembly comprises a poppet valve having a pair of poppets on a valve rod and a spool valve movable in response to the operation ...

An improved label feed comprising a first roller means for feeding an elongated parent strip of label material into the labeling apparatus, guide means in advance of the first roller means, cuttng means in the form of a rotary blade and an oscillating stationary blade adjacent the guide means for severing individual labels from the parent strip, and second roller means in advance of the cutting means for feeding the label strips onto a vacuum drum or the like for application to containers. A lea...
