Title: Cylinder liners
Inventor: TOMMIS NORMAN
IPC: C23C8/32
Filed: 1984-08-28
Abstract: A cylinder liner is produced from a mild steel by pressing, drawing or extruding to a tubular shape and then finish machining. The finally shaped liner is then nitrocarburised with a mixture of carburising and nitrogenous gases to form a hard "epsilon" layer on the liner surfaces. The liner so produced requires no subsequent finishing processes, can be pressed into an engine block without brittle fracture and is resistant to both exterior wear from water, in a wet liner, or from the engine block, in a dry liner, and interior bore wear from an associated piston and piston rings.

Title: Automated burn-in board unloader and IC package sorter
Inventor: GUSSMAN ROBERT LEE
IPC: H05K13/04
Filed: 1984-10-25
Abstract: IC packages are unloaded from sockets on a burn-in board according to predetermined performance grades. The IC packages are displaced from the sockets by inserting tools through passageways extending through the burn-in board 32 and socket to contact the underside of the IC package and push the IC package from its socket. Sorting is accomplished by collecting the displaced IC packages of a particular grade and storing them separate from all other IC packages. As burn-in board 32 is traversed under channels 92, pusher means (not shown) are selectively energised to pass through holes in the board to push packages of given performance standard into sloping grooves 62 down which they pass for collection in plastics tubes stored in racks 30; the apparatus is automatically controlled by means 24. <IMAGE>

Title: Method for the concentration of viruses from fluids
Inventor: NEEMAN ISHAK
IPC: C12Q1/70
Filed: 1985-05-28
Abstract: Virus-containing fluids such as sewage and biological fluids are contacted with an adsorbent matrix comprising animal erythrocyte ghost cells. The resulting matrix is acidified whereby the viruses adsorbed are separated as a precipitate. Subsequently the precipitate is eluted, by a solution having a pH above that prevailing during the acidifying step, preferably by a buffer solution having a pH of above 6.5, thus obtaining a concentrate of the corresponding viruses. The adsorbent matrix may be either in the form of particulate solid particles (as a bed, column, cartridge), or coating on an adequate support. A preferred form of the adsorbent matrix is a continuous film such as a membrane.

Title: Apparatus for adhesive tape manufacture
Inventor: YU DAVID
IPC: B05C9/04
Filed: 1988-03-17
Abstract: Double-sided adhesive tape is manufactured by pulling plastic tapes (1) downward over adhesive-applying tubes (41, 42) transversely placed in the central portion of the tape path.

Title: Determination of area of drawings
Inventor: MARINAKIS MICHAEL
IPC: G01B11/28
Filed: 1989-06-09
Abstract: The invention makes use of a natural quantity, e.g. the weight, of a sheet of paper or other drawing material, and of the correlation of this weight to the area of the same drawing material, whereby a coefficient of weight per unit area is established so as to determine the area of any particular drawing by cutting, and weighing the said area and using the coefficient to determine the area of the cut-out portion. Drawing paper 4 containing a marked area 5 is placed on a transparent table 1 so that a light beam from a source 11 can be received by a sensor element 12.

Title: Swageable hose end fitting for very high pressure hoses
Inventor: TAKEN COLIN JAMES
IPC: F16L33/207
Filed: 1989-06-21
Abstract: An end fitting for a very high pressure wire-reinforced hose (11) which is pared and clamped between stem and ferrule members (10 and 25) of the fitting. The stem member (10) has two longitudinally spaced shoulders (17 and 18) which are spaced apart by a circumferential groove (19). The ferrule member (25) incorporates two spaced-apart grooves (32 and 33) which locate about and complement the stem member shoulders (17 and 18), and a shoulder (34) that locates about and complements the stem member groove (19). The various shoulders and grooves in the two fitting members (10 and 25) co-operate to force a projecting end of the hose reinforcement to assume a serpentine path and to positively lock the reinforcement between the two members. Additionally, the ferrule member (25) is formed with a number of inwardly projecting circumferential ribs (30), each of which is surrounded by a circumferentially extending land (37), and the ribs and lands co-operate to effect localised concentrated clamping of the hose reinforcement when the ferrule member (25) is swaged onto the stem member (10). <IMAGE>
