In a feed pump (2) designed as a side channel pump, with an impeller (5) rotating in a pump casing (3) and having blade chambers (12, 13), the blade chambers (12 13) have an inflow region (16, 17), the profile of which is designed asymmetrically to that of an outflow region (18, 19). The feed pump (2) can thereby be adapted to an intended characteristic simply by exchanging or reversing the rotation of the impeller (5).

The present invention relates to a bioactive feed pellet comprising besides commonly used nutritionally valuable components, a biologically active ingredient such as a therapeutically or prophylactically active compound, a vaccine, a pigment, a vitamin, and/or an enzyme, whereby the bioactive ingredient has been applied to the pellet in the form of a primary coating dispersion and/or emulsion and/or solution in a fatty component or a mixture of dietary oil, said component or dietary oil comprisi...

A dry cattle feed comprised of 80% to 87% hardwood meal naturally containing phosphorous, potassium, calcium, magnesium, sodium, zinc, iron, copper, and manganese harvested from all varieties of oak, pecan, and mesquite trees.

A rotationally mounted cam for use with an archery bow. The cam comprising a primary string feed-out, a secondary string feed-out and a string take-up. The primary string feed-out feeding out a predetermined amount of string when the cam rotates about an axle as the bow is drawn. The secondary sting feed-out arm having an end of the string anchored thereto. The secondary string feed-out independently rotationally mounted to the cam at a rotation point. The cam providing the bow with the capabili...

The present invention relates to a fastener supply system and, more particularly, to a fastener supply system which uses a plurality of feed stands mounted upon a turntable which are automatically positioned to ensure continuous fastener feed. The system detects the flow of fasteners at one or more power feeders and when the fasteners are getting low, rotates a new supply of fasteners to the power feeder and begins to supply fasteners before the installation head supply is interrupted. The opera...

A feed wheel (24) for use in a wood working machine (10) in which the feed wheel is rotated while in driving engagement with a wood piece to drive the wood piece past a wood working element. The feed wheel is preferably driveable in one direction only and is freely rotatable in the direction opposite to that for feeding. The feed wheel is preferably formed of a hub part (40) and a rim part (38) which is separable from the hub part. The rim part includes teeth arranged to extend at a helix angle ...

In a feed pump designed for feeding fuel in a motor vehicle and having two feed chambers (11, 12) located opposite one another, of which one is connected to an inlet port (18) and the other to an outlet port (19), the feed chamber (11) connected to the inlet port (18) has a calming region (21) which a compression region (22) adjoins. Fuel entering the feed pump is thereby first calmed. Subsequently, in particular, gas bubbles present in hot fuel are dissolved due to the vapour pressure in the fu...

In a feed pump (2) designed as a peripheral or side channel pump, guide vanes (9, 11, 12) arranged in an impeller (4) have a different angle of inclination in the radially inner region from the radially outer region. As a result, the characteristic curve of the feed pump (2) can be modified simply by exchanging the impeller (4). By virtue of the invention, the feed pump (2), whilst having an intended feed pressure and volume flow, can be set to particularly high efficiency, depending on the visc...

An improved vertical feed mixer has a mixing chamber defined by a floor, a sidewall, and an open upper end through which feed material, such as hay bales, is loaded into the chamber. A vertically disposed auger with tapered flighting is rotatably mounted within the chamber for cutting, mixing, and discharging the feed material through a discharge opening near the bottom of the chamber. A plurality of grader blades extend outwardly from the auger shaft in close proximity to the bottom wall of the...

An enzyme feed additive is provided comprising a xylanase, a protease, and optionally a .beta.-glucanase. The ratio of the units of xylanase activity per unit amount of the feed additive to the units of .beta.-glucanase activity per same unit amount of the feed additive is 1:0-0.25. Preferably, the xylanase is the low pI xylanase and/or the high pI xylanase obtained from Trichoderma longibrachiatum. Preferably, the protease is a mutant subtilisin comprising a substitution at the amino acid resid...
