Title: Mould for resin injection of composite panel faces - allowing lateral mould flooding and frontal ejection
IPC: B29C45/28
Filed: 1972-11-09
Abstract: Mould tool is used for injection of the resin component of a composite panel with a core of rigid expanded foam or of baled wood and surfaces of glass fibre reinforced resin. The mould comprises a rectangular frame with a separate base and a hinged lid. When closed, the cavity is sealed on 3 sides but vented on the side opposite the side through which the resin is injected. Pref. the resin is injected at controlled rates to flood the cavity on a broad front. After moulding the base panel can be dropped to allow levers to push the moulding downwards after the lid is opened. PRef. the 3 sidewall joints have elastic seals. Mould is used for mfr. of panels with smooth surfaces on both major faces, it introduces resin build-up more rapidly and reproducibly than hand lay-up, with less risk to trapping air or crushing or excessive impregnation of the core with resin.

Title: Travelling clamps for holding extruded sheet for thermo-forming - to support hot sheet and prevent lateral shrinkage
IPC: B29C48/08
Filed: 1974-03-01
Abstract: Twin pairs of opposed travelling chain clamps are provided for gripping and moving freshly extruded thermoplastic sheet by its edges, the transport speed of the chains being synchronised with the extrusion rate of the sheet.

Title: Wood chip board having predetermined moisture content - formed by hot pressing in two stages in which temp is program controlled
IPC: B27N3/20
Filed: 1975-09-16
Abstract: Wood chip mats containing adhesive are hot pressed between electrically heated presser plates and during a first pressing period the temperature of the plates is gradually increased to a desired level under programme control, after which the temperature is maintained constant at this level until the end of the pressing operation. A wood chip panel is produced. The residual moisture contained in the resulting panel is controlled to be 1-4% thereby making a better quality panel. Pref. during the first pressing period the pressure applied to the panel is also under programme control and is then rapidly reduced to a value just below the vapour pressure of the water contained in the panel. Gradually towards the end of the overall pressing operation the pressure is reduced to zero. Pref. the temperature is controlled to produce a temperature gradient in the panel below 0.50 degrees C/S.

Title: Eccentric rotary piston compressor - with separator slide in housing loaded by spring effective over part of downward stroke only
IPC: F04C18/356
Filed: 1975-10-22
Abstract: The compressor is of the type having an eccentric piston rotating in a cylindrical housing provided with a spring-loaded separator slide engaging the piston to define a suction and a pressure chamber. The slide is provided with a spring whose characteristic shows a sharp bending point such that, after the slide has travelled a certain distance of its downward stroke towards the centre of the compressor, part of its spring force becomes ineffective, and during the subsequent upward stroke it comes back into effect from the sauce point. This may be achieved by the spring engaging a shoulder in the housing. There may be two springs, a stiff and a weak one, arranged in series.

Title: Assembly of components while mfg. moulded plastic component - with interference fit by local elastic deformation of projections
IPC: B29C65/58
Filed: 1976-01-21
Abstract: Method for assembling a first component of moulded thermoplastic material and a second rigid component of any material is carried out by force fitting projections on the second component in at >=1 seat formed by moulded recesses and/or projections on the first component, while the first component is leaving the mould and still in the plastic state. Force fitting is performed by localised elastic deformation of the seat on the first component, with elastic return of the deformed edges to their original position to fix the projections of the second component in position. These edges are then stabilised by hardening the material with cooling of the first component.

Title: Open fireplace for domestic heating - has refractory construction with air flue adjacent backing and water vessel above hearth
IPC: F24B1/183
Filed: 1976-01-16
Abstract: An open fireplace has a hearth on which wood is burnt. The smoke passes through an opening above the hearth into a chimney which is built on the back of a wall separating the room containing the fireplace from an adjacent room. The partition is made of refractory material. An air flue is built in the adjacent room backing the refractory partition. Air enters at low level and is discharged at high level. It is heated in the flue by heat transfer through the refractory partition. A water vessel built through the partition above the hearth is also heated by the fire. The fire thus provides direct heat, warm air heating and hot water.

Title: Pneumatic threader for yarn through double twister spindle - has axial bore from below connected to air supply
Inventor: CHARBONNIER SIMON
IPC: D01H15/007
Filed: 1976-01-28
Abstract: The end of yarn from the spool is threaded through the shank of double twister spindle, by feeding a compressed gas along an axial bore from below through the spindle. The bore opens out obliquely to the spindle circumference at the level of the outlet for the thread from the upper end of the spindle, into a guide channel much larger in diameter than the outlet for the thread, so as to create a suction in the spindle bore. The gas used is air, and fixed lines with valves and connections beneath the spindle brackets are provided so that compressed air is immediately available when required. The threading of the yarn down the bore of the spindle and out through the support dish takes an appreciable time whether the end is drawn through by a probe or sucked by a bellows. Previous devices for injecting air across the bore at the base of the spindle to suck the thread through, have the objections of complicated and expensive design.
