Title: Re-use of thermoplastic scrap - by reprocessing mixtures of different resin mouldings into thick walled components with fibrous texture
IPC: B29B17/02
Filed: 1972-07-17
Abstract: Recovered pieces of film, foam, sheet, mouldings etc. comprising principally polyolefins, polystyrenes or vinyl resins are if necessary firstly isolated from other materials by conventional sorting, washing and milling techniques. The resulting dried ground mixture of recovered resins is analysed and then enriched if necessary with selected resins to create a roughly standard compsn. This adjusted feedstock is then dried with a blowing agent and reprocessed using temps. higher than those required by any of the component resins in the pure state, usually at 150-180 degrees C, to obtain an extrudate or (injection) moulding with a fibrous cellular structure, with a surface which normally consists preferentially of PVC with a highly glazed surface. The mixture may contain some particles of other materials such as polyamides or comminuted papers which are infusible at the reprocessing temp. used and which act as filler grains within the body of the product component. Method is used in mfr. of relatively thick walled components such as synthetic planking, being receptive to screws, nails, or similar fastenings, self extinguishing w.r.t. flammability, dimensionally stable and rot-proof.

Title: Emulsifier for foundry moulding sands - to prevent sticking to pattern surfaces
IPC: B22C1/22
Filed: 1973-06-15
Abstract: A method of making cores and foundry moulds is claimed in which a mixt. of sand, a salt which on heating forms an acid, and a resin esp. of the urea-phenol-formaldehyde type, characterised in that 0.2-2 wt.% of an emulsifier is added, which comprises 20-80 wt. pts. of a fatty acid, an oil, a paraffin hydrocarbon or a distillation residue therefrom and 20-80 wt. pts. of diluent based on oil or coal distillate and 0-10% of a classic emulsifier.

Title: Case or desk with removable section - has flexible partition between sections and adjustable work surface
IPC: A45C11/00
Filed: 1973-06-25
Abstract: Considering that in a brief-case of this type both papers, books, pens and other hardware directly related to the activity to be performed, as well as other objects such as glasses, cigarettes, etc are to be stored and carried, and that each of these may have multiple roles, a new concept of its internal partition and operation is proposed. The main aim of the invention is to drastically reduce the number of operations required to make available the needed material or, conversely, to store it once the work is terminated. The desk has a main chamber and a smaller chamber, a flexible partition separating the two. The smaller chamber is removable or adjustable to provide a suitably inclined work surface.

Title: Anti-splash system for liquid container on vehicle - inner flexible membranes moved by fluid pressure to expel liquid
IPC: B65D88/62
Filed: 1974-02-19
Abstract: A liquid container with outlet flow control device, on a vehicle, is divided internally into separate compartments (7) by dividing walls. Each compartment has a flexible membrane (10) placed against its outer wall. Perforated screens (15) placed across the corners at the separating wall junctions form outlet flow channels connecting with the outlet pipe (3). Fluid pressure is introduced between the outer wall and the membranes to expel the liquid. The membranes can move until pressed against the separating walls. Each outlet channel (16) is connected to the outlet channel via an opening (19). A ball (22), slightly larger in diameter than the tube, opposes movement of liquid due to acceleration forces by being moved to block one or other of the openings.

Patent FR-2269665-A1 (FR)
Title: Fluid duct pressure regulating valve - control diaphragm failure results in valve closing against high pressure supply
IPC: F16K17/20
Filed: 1974-07-19
Abstract: A poppet valve (8) is mounted on a spring loaded (18) piston (16) by a shaft (15). The piston and spring are contained in a cylindrical housing (11) of slightly greater diameter than the piston. A flexible diaphragm (14) connected to the piston seals off the spring housing from the fluid duct (5, 6). The pressure in the upstream manifold (5) acts in opposition on the areas of the valve (d1) and diaphragm (d2) which are equal. Valve position is thus independent of upstream pressure but does depend on spring setting (21) and downstream pressure. The piston area (d3) is greater than the active diaphragm area (d2) so that if the latter fails, the piston is forced up and the poppet valve closes. Orifice (22) prevents pressure building up on the upper side of the piston and restricting its movement.
