Title: Batch reception station for winemaking grapes - which checks wt. and quality of each batch for process control and purchase price
IPC: B65G/
Filed: 1975-03-05
Abstract: A plant installation is claimed for the reception, weighing and onward transfer of a batch of freshly gathered grapes to winemaking operations and/or storage vessels. The plant is a combination of:- (a) a reception hopper into which the batch is tipped, the hopper being mounted on the weighing platform of a mechanical or other type of weighing device, e.g., load cells; (b) a pump rigidly fixed to the hopper from which it is to pump the must which passes from the hopper into the pump suction; (c) means to ensure that hydrostatic loading in the pipework on the delivery side of the pump is not transmitted back to give rise to errors in weighing the batch. Pref. the pump outlet is connected to the onward transfer pipe via a deformable coupling or a telescopic gland coupling and an isolating stop valve is fitted between the coupling and the transfer pipe. A sampling branch for must is fitted in the pump delivery, as near as possible to the pump. Must analysis, to determine batch allocation via a multi-way valve at the end of the transfer line, is pref. completed in the time taken for the start of the batch to be pumped from the hopper to the multi-way valve. Using only a single reception hopper, the wt. and the quality of each batch is individually assesses so that process allocation can be decided at once and the batch supplies eventually paid on a wt./quality basis.

Title: Moulding resin impregnated foam and fibrous sheets laminate - using high frequency field to effect polymerisation
IPC: B29C70/00
Filed: 1975-12-11
Abstract: Fibre reinforced plastics mouldings are produced by impregnating an expanded plastics sheet with a thermosetting resin, forming a laminate of the sheet with a fibrous sheet, compressing the laminate in a mould to transfer the resin into the fibrous sheet, polymerising the resin and demoulding after hardening of the resin. The improvement consists in polymerising the resin by subjecting the laminate to a h.f. electric field after cold compression of the laminate. Process avoids the use of external heat for effecting polymerisation and, therefore, attendant drawbacks e.g., viscosity variations in the resin, air occlusion, separate heating of different parts of complex moulds etc. Heating by dielectric loss is more homogeneous and rapid throughout the thickness of the laminate.
