The present invention relates to heat tolerant phytases and DNA sequences which code therefor. The phytases are useful in hydrolyzing phytate to inositol and inorganic phosphates. The phytases are valuable feed additives.

Heat tolerant phytases

The coupling is provided with a load bearing plate (6) tiltably mounted on a circular plate (10) supported on the tractor for rotation about a substantially vertical axis (20). The load bearing plate receives, in a slot (7) formed therein, a pair of spaced apart kingpins (1,3) on the underside of the trailer (A) in such manner that the trailer and the two plates are restrained from rotation with respect to each other. A pair of fluid operated rams (29,30) are mounted on the tractor and are arranged to cooperate an opposite sides of said axis (20) with rollers (35,36) carried by the circular plate via a pair of swinging arms (23,24) pivoted on a center shaft at one end and on the ends of the ram piston rods (27,28) near their opposite end. Thus only one ram at a time may become operable to resist rotation of the plates away from an in-line position of the tractor and trailer or to restore this position, to avoid trailer swing or to cure a jacknifing condition, without the piston rods fouling the center shaft.

Coupling for an articulated vehicle or the like

In this arrangement, the pitching, rolling and steering movements that take place between a motor car and a trailer are separately accommodated, with the pitching movements being accommodated by a horizontal transverse hinge structure arranged to be nearest the towing vehicle and comprising two relatively moving parts, motion therebetween occurring through an elastic member. A device is provided for stressing the elastic member in a variable and controlled manner whereby weight may be taken off the rear axle of the car to a desired extent and distributed to the front axle of the car and to the trailer axle. The rolling movements are accommodated by a stub-shaft at the front of the trailer, rotatably inserted into a longitudinally extending horizontal hole provided in the second of the above moving parts, and the steering movements are accommodated by an eye at the rear end of the stub-shaft, pivotally engaged in a fork-like member, carried by the trailer towbar, for motion about a vertical axis.
