Title: Optical trackers
Inventor: ACKROYD JOHN
IPC: G01S17/66
Filed: 1982-09-07
Abstract: An optical tracker wherein an electronic real-time spatial light modulator 4 holds an image of a viewed scene and, in accordance with that image modulates an internally generated beam 21 of coherent radiation. The resulting signal beam is Fourier transformed (by lens 8 say) and passed to an optical transform filter 9 which is matched to an object, a possible target say, to be detected within the overall viewed scene. The transform filter may comprise a photographically pre-formed member matched to the general characteristics of a likely target but, preferably, it comprises a further electronic real- time spatial light modulator in which a Fourier transform hologram image representative of the target is formed during an image forming or updating step in the tracker operation. This is done by using an optical switch to pass a reference coherent radiation beam to the further modulator along with the signal beam. <IMAGE>

Title: Weigh frame
Inventor: PACKER BRIAN WILLIAM
IPC: G01G11/04
Filed: 1983-10-05
Abstract: A weigh frame for a belt conveyor has an idler roller 2 supported on a support member by a pair of idler support brackets 3. Load on the belt 12 is transmitted by the idler roller 2 and the support brackets 3, and is detected by strain sensing means 13 mounted on the support member t to measure its deflection. The support member 1 is mounted on the frame of the conveyor in such a way, e.g. by pivot joints 5, 6, 7, 8, that forces transmitted from the frame to the support member 1 are perpendicular to the support member 1. The relatively simple "bolt-on" weigh frame has improved accuracy as distortions caused by stresses in the conveyor frame are reduced. <IMAGE>

Title: A process for the production of a protein
Inventor: LOWE PETER ANTHONY
IPC: C12R1/19
Filed: 1984-03-23
Abstract: In a process for the production of a soluble native protein, such as immunoglobulin or methionine-prochymosin, in which an insoluble form of the protein is produced by a host organism transformed with a vector including a gene coding for the protein, the insoluble form of the protein is reversibly denatured in an alkaline aqueous solution at a pH selected to promote dissociation of a group or groups of the protein involved in maintaining the conformation of the protein, and the protein is subsequently allowed to renature by reducing the pH of the solution below a pH effective to denature the protein to produce the soluble native form of the protein. The pH of the alkaline aqueous solution is suitably in the range 9.0 to 11.5.

Title: Drive line for transmitting power from a tractor to an implement pulled by the tractor
Inventor: FRANET ROGER
IPC: A01B71/06
Filed: 1985-03-05
Abstract: A drive line (26) for an implement (14) attachable to a tractor (10) includes two double cross bearing universal joints (32 and 34). During turns between passes over crop the power delivered by the line must turn through a working angle as large as 90 DEG . but for such a tight turn each joint turns the power through two angles of only 22 1/2 DEG  thus enabing full power to be used between passes without undue wear. The implement (14) is attached to lower links (18) of the tractor (10) by way of a yoke (16) which in turn is connected to a drawbar (12) of the implement (14) via a pair of channel-shaped supports (20, 22) rigid with, and at right angles to, one another. One support (20) receives the forward end of the drawbar (12) in its channel and is connected thereto by a vertical pivot pin (21). The other support (22) similarly receives the yoke (16) to which it is connected by a horizontal pivot pin (23). There is thus provided a drive and an arrangement for attaching the implement (14) to the tractor (10) which permits tight turns to be made efficiently.
