Title: Wheelbarrow with spring suspension
Inventor: CLEMENTS ROBERT JAMES
IPC: B62B1/18
Filed: 1984-05-01
Abstract: The single wheel is carried by a trailing-arm which is linked to the frame or chassis of the wheelbarrow via a torsion device consisting of an outer steel tube, which is concentric with a solid bar, the space between the tube and bar being filled with moulded rubber which acts as a shock absorber as well as a torsion suspension. The solid bar of the torsion device fits into a position which would be the axle in a conventional wheelbarrow. This suspension unit allows a wheelbarrow to traverse rough ground with the minimum of effort and with little spillage of the material being carried. When tipping the load, in the usual up and over mode, the suspension unit will act as a self-adjusting fulcrum by moving closer to the surface on which the load is being dumped. <IMAGE>

Title: Process for purifying chymopapain
Inventor: ORAY BEDII N
IPC: C12Q1/37
Filed: 1984-07-03
Abstract: A process which permits the commercial scale isolation of large amounts of homogeneous populations of Chymopapain B or Chymopapain C, free from cross-contamination and other proteins and with low levels of pyrogens, from either papaya latex or crude chymopapain preparations.

Title: Moulding container closure sealing gaskets
Inventor: STROUD GASTON ALBERT
IPC: B29C35/08
Filed: 1986-06-17
Abstract: A method is described of forming microcellular gaskets from vinyl chloride plastisol in container closures made from high melting olefin polymers especially polypropylene. The liquid plastisol sealing compound within the container closure is heated both by conventional thermal means and also by microwave energy. Thermal heating is used to attain a temperature between 100 DEG and 130 DEG C in the container closure, whilst allowing the microwave energy to heat the plastisol to a temperature sufficient both to decompose the blowing agent within the plastisol and to fuse or flux the gasket, generally between approximately 170 DEG  and 195 DEG C. The microwave heating of the plastisol is carefully controlled so that the transfer of heat from the gasket to the polyolefin closure does not cause the closure to soften or distort.
