Patent GB-2030920-A (GB)
Title: Producing coated spheroidal particles
IPC: C21C1/10
Filed: 1979-08-16
Abstract: Spheroidal particles of a first material, especially a metal, are made by applying a gyratory motion to a container carrying a powder of the material and a binder. The particles are then coated with a second material, such as Al2O3, TiN or zircon, by adding a powder of the second material with a binder and continuing the gyratory motion. Finally, the coated particles are sintered. The structure of the coated particles is able to accommodate shrinkage during sintering without deleteriously affecting the integrity and adhesion of the coating. Also, a wide range of combinations of first and second materials may be used. A particular application of the coated particles is as inoculants to be added to a melt.
Patent GB-2056589-A (GB)
Title: Clutch assemblies
IPC: F16D13/52
Filed: 1979-08-22
Abstract: A drive sprocket (1) is driven through interleaved clutch plates (12, 5) from a rotating clutch centre (3) interconnected by drive pins (8) with a pressure plate (4) which bears on the clutch plates. Pressure is applied to the pressure plate (4) by Belleville dished spring washers (15) reacting against a cover plate (6). The dished washers (15) apply an even pressure to the pressure plate (4) and allow for delicate control of the extent of clutch release (or slip) because the dished washers have a power curve which flattens off as maximum compression is applied. The clutch is particularly suited for the control of racing motor cycles. <IMAGE>

Patent GB-2042963-A (GB)
Title: Method and apparatus for producing hollow plastic microspheres
IPC: B01J13/22
Filed: 1979-08-17
Abstract: Hollow plastic microspheres (17) made from thermoplastic or thermosetting plastic compositions. The hollow plastic microspheres (17) are made by forming a liquid film of thermoplastic or thermosetting plastic composition across a coaxial blowing nozzle (5), applying a blowing gas (10) at a positive pressure to the inner surface of the plastic film to blow the film and form an elongated cylinder shaped liquid film (12) of plastic.

Title: Fluid couplant containers
IPC: G01S7/52
Filed: 1980-02-04
Abstract: A fluid container (10) for containing a fluid in contact with the top of a body being ultrasonically scanned. The container comprises fluid-impervious material (20) and an opening to be placed on the body, for example over the breasts of a female torso.

A method is also described which is particularly easily carried out using the container (10). It entails matching the impedance of a liquid couplant in the container to the impedance of examined body tissue. The time per unit distance taken for ultrasonic pulses to travel through body tissue and a reference liquid respectively are found and the reference liquid mixed with a second liquid in a ratio dependent on the difference between those times to form a liquid couplant with an impedance similar to the impedance of the body tissue. <IMAGE>
