Patent GB-2099581-A (GB)
Title: Endoscopic probes, systems and methods
IPC: A61B1/00
Filed: 1981-05-28
Abstract: An endoscopic apparatus provides for simultaneous visual and ultrasonic imaging of internal body parts through the use of a probe (10) insertable into a body cavity. The probe (10) includes a rectilinear ultrasonic transducer array (70) acoustically coupled to the body through a cylindrical focusing lens (82) having an outer face which conforms to the probe contour. The transducer array (70) is included in a pulsed ultrasonic imaging system of the B-scan type. A tube (14) connects the probe to a control housing (12). The pulsed ultrasonic imaging system includes pulse generator and pulse receiver means connected to individual elements of the transducer array (70) by coaxial cables extending through the tube (14). Electronic beam focusing and scanning means for rectilinear B-scan operation are provided for imaging of objects at close distances adjacent the probe (10). Visual display means (124) is provided for display of the ultrasonic image from the B-scan receiver. An optical illuminating and viewing system is provided for optically viewing internal body parts through the probe (10), which system includes an objective lens (28) and illuminating means adjacent the distal ends of the probe (10) and transducer array (70). A removable eyepiece at the housing (12) is used for direct viewing by the operator while guiding the probe (10) into a desired position in the body cavity. The optical image can also be viewed by a video camera having an output connected to a monitor (40) adjacent the ultrasonic image display means (124). Consequently, both the optical and ultrasonic images are simultaneously displayable and viewable by the operator. <IMAGE>

Title: Coimmobilisates from fermentable yeasts with coupled enzymes as well as their production and use
IPC: C12P1/00
Filed: 1981-06-05
Abstract: Living, fermentable yeast cells are prepared having an enzyme or mixture of enzymes coupled thereto. Enzyme coupling is carried out by contacting at least partially dehydrated living yeast cells with an aqueous enzyme solution to cause the yeast cells to rehydrate and a layer of enzyme to form on the surface of the yeast cells, and than contacting the rehydrated yeast cells with an enzyme-precipitating solution which optionally contains a cross-linking agent to cause the enzyme to become attached to the yeast cells. An aqueous solution of tannin is preferably the enzyme-precipitating solution and gluardialdehyde is preferably the cross-linking agent. Pepsin coupled to Saccharomyces yeast, when used to ferment grape must to produce wine, results in practically foam-free attenuation, quicker fermentation and better self-clarification. Saccharomyces yeast having amgloglucosidase coupled thereto may be used to ferment beer wort to produce a diet beer.

Title: Production of lightweight aggregate material
Inventor: THOMPSON FAX FARM DOUGLAS OSBO
IPC: C04B20/06
Filed: 1982-11-11
Abstract: Bloated clay is produced in a fluidised bed furnace by introducing moisture-containing particles of clay into a fluidised bed of inert material (e.g. alumina) in a fluidised bed furnace, the moisture-containing clay particles being of higher density than the fluidised bed of the furnace and the temperature of the furnace being such that the clay particles are caused to bloat and become less dense than the fluidised bed so that the bloated clay particles formed float to the top of the fluidised bed from whence they are removed. In addition formed articles are produced from particles of bloated mineral material, particularly such particles made by the above process, by heating such that their outer walls are soft, pliable and tacky and forming the hot tacky particles together under pressure to the required shape.
