Title: Flexible coupling for shafts - has two identical plates with projecting dogs formed from sheet metal, interlocking and separated by elastic material
IPC: F16D3/68
Filed: 1975-10-09
Abstract: This design of flexible coupling for shafts avoids the need for costly tooling and machining, by constructing all the components in the halves of the coupling from sheet steel. The coupling has two drive faces each consisting of five dogs (31) projecting from a plate (27) which are identical. When assembled face to face the spaces between the dogs are filled with elastic material in the form of plugs. In the present design, each dog is made separately from sheet steel and is attached to the support plate (27) by bonding or welding. Internal (30) and external (28) rims on the plate position the dogs radially and the whole assembly is held in a housing again made from sheet steel. The housing consists of a sleeve (22) carrying a circular plate (24) with a rim (25) which surrounds the support plate rim (28). The two plates (24,27) may be spot welded together and the sleeve a shrink fit on the hub (20) held by the drive shaft. If desired, the sleeve may be omitted and the plate (24) extended beyond the rim to form a flange for bolting to e.g. a flywheel.

Title: Filter tips for tobacco smoke - made from corrugated paper contg. thermoplastic olefin polymer with added carbon particles
Inventor: BAUMANN LAWRENCE LEE
IPC: A24D3/04
Filed: 1976-12-08
Abstract: Filters for tobacco smoke consist of a filtering tube made from paper corrugated in the longitudinal direction; the paper contains 5-50% by wt. of thermoplastic olefin polymer pref. high density polyethylene or polypropylene, fibres. The fibres may be 1-10 mm long with a specific surface area of 5-70 m2/g and the paper may contain sulphite and/or sulphate pulp. The paper may have additional particles, e.g. of carbon, bonded to its surface by the olefin polymer fibres. A continuous length of the filter tube is subsequently cut into short lengths to form filter tips. The original tube, or the individual lengths, are heated to soften the fibres and bond the whole assembly together. The filter tip contg. the thermoplastic fibres shows a lower press. drop and improved hardness is compared with the corrugated paper used hithto. There is the added advantage that particles, such as activated carbon, may be bonded, by heating, to the fibres without the need for an auxiliary adhesive.
