Patent FR-2317112-A1 (FR)
Title: Tyre tread with sloping tread crowns - to reduce peel damage due to local compression
IPC: B60C11/03
Filed: 1975-07-07
Abstract: The surface profiles of the crown zones of the tread blocks are relieved at a shallow angle or depth over most or all of the surface. They are for tyres for vehicles carrying heavy loads. The tread surface can readily deform slightly if impinging on high points on the road surface or terrain. The deformation reduces local compressive and shear stress concentrations and hence damage due to 'peeling'.

Title: Electrode construction for bipolar cells - esp of the filter-press type for electrolysis of halide solns
IPC: C25B9/20
Filed: 1975-08-25
Abstract: In an electrode construction for a bi-polar electrolytic cell, an electrode in the form of a grill or mesh is attached to at least one side of a corrosion-resistant electrically conductive base plate so that a small space exists between them. The electrode is welded to the base plate at several points either directly or using connection pieces. The connection piece can be in the form of a rod or plate, and the latter can be attached to the base plate by explosion welding. The electrode is used in the electrolysis of alkali-metal halide solns., e.g. mfr. of chlorates, hypochlorites or perchlorates. It has low potential drop; generated gas is quickly removed from electrode surface; electrode can have twice the effective surface area of a plate electrode; voltage elevation resulting from hammer esp. on cathode and polarisation of electrodes by gases both minimised and accurately produced thin electrodes permit high output from small cells.

Title: Protective screen for shower bath - is built up from hinged strips used for drying clothes
IPC: A47K10/04
Filed: 1977-03-01
Abstract: One wall of a protective screen for a shower bath is built up from a number of strips (2). Each strip (2) has an eye formed at one end which fits over a corner pole (3).

Title: Wood-fuelled central heating boiler - has closed air jacket around fire box above which is water coil for heating by indirect exchange
IPC: F24H1/38
Filed: 1977-04-26
Abstract: The boiler has a rectangular casing (1) within which there is a cylindrical combustion chamber (2). This has a grate (3) and an ash pit (4) below it.
