Title: Optical communications
Inventor: MILLER LEE DOUGLAS
IPC: H04B10/00
Filed: 1992-10-24
Abstract: An optical communications system which facilitates rapid establishment of communications between two stations (1, 2). The system uses acousto-optic cells (5, 6) for scanning and frequency modulating a laser beam. The frequency shift introduced by the cell (6) is indicative of the direction of arrival of the beam at a remote station (2). By detecting said shift, the relative positions of the two stations (1, 2) may be deduced. Each station successively broadcasts the result to the other which stops scanning locking onto that position. The invention is suitable for use with secure communication systems and IFF systems. <IMAGE>

Title: Reduced fat meat
Inventor: ROEHRIG PAUL GENE
IPC: A23L13/50
Filed: 1993-01-28
Abstract: Sources of meat having a high fat content, such as meat trimmings, are processed in a manner by which meat products prepared therefrom have a dramatically reduced fat content while retaining the desirable functionality of the unprocessed meat sources. The fat-containing meat trimmings or the like are comminuted, heated and centrifuged under specific processing conditions in order to provide unformulated raw reduced fat meat having a fat content of not greater than on the order of about ten percent by weight while having excellent functionality. The unformulated reduced fat meat is formable into a variety of familiar meat products, including wieners, sausages, hamburger patties, and the like, thereby providing products having taste, appearance, texture and other qualities which are substantially indistinguishable from products prepared from high fat unformulated raw materials but which have dramatically reduced fat contents.

Title: Crack detection in a sheet of material around a fastener hole
Inventor: SARGENT JEFFREY PAUL
IPC: G01N29/04
Filed: 1994-08-24
Abstract: Cracks (14) can be detected in one or more sheets (1, 2) of material such as aluminium in the vicinity of a fastener hole (3) through the sheet whilst the fastener remains in position in the hole (3). Two focussed longitudinal wave ultrasonic transducers (4, 5) are located at an angle to the top surface of the top sheet (1) on diametrically opposite sides of the fastener and hole (3), coupled to the sheet surface and pulsed ultrasonic energy is fed to one transducer (4) and converted therein to a focussed shear wave beam (6) which is passed in transmission obliquely into the material in the direction of the hole (3) and any crack if present. The presence of a crack creates a shadow region by relative changes in acoustic transparency through the sheet material which shadow region is picked up by scanning the other transducer (5) in synchronism with the transducer (4) and presented visually whereby both the position and size of the crack can be ascertained directly or indirectly from the visual image. <IMAGE>
