Title: Device for vacuum moulding for the manufacture of cooked and semi-cooked pressed cheeses
Inventor: PIERRE MEGARD
IPC: A01J25/12
Filed: 1990-11-20
Abstract: The device comprises a moulding cylinder (1) of vertical axis (2), with a lower part (5) of circular horizontal cross-section surrounded by a jacket (6) inside which the side wall of a cheese mould (9) can be introduced. The jacket (6) has a polygonal, for example square or rectangular, horizontal cross-section, into which fits the circular horizontal cross-section of the lower part (5) of the moulding cylinder (1). For the manufacture of the cooked pressed cheeses, the jacket (6) receives a mould (9) of circular horizontal cross-section. For the manufacture of semi-cooked pressed cheeses, the jacket (6) receives a cheese mould of polygonal horizontal cross-section, corresponding to the cross-section of this jacket, the curd which is deposited in the mould is subjected, in this case, to a subsequent cutting operation. The moulding device thus constitutes a versatile equipment for cheese factories.

Filed: 1991-12-27
Abstract: In order to fractionate an "effective" colour space (ECS), which corresponds to a set of "basic" chromatic components (BCCs) intended for a particular industrial application, (1) the ECS is estimated by selecting a reference colour space (RCS) including the ECS and by determining the trichromatic co-ordinates (L1, a1, b1; L3, a3, b3 ...) of said BCCs in the RCS, by means of measurements of the full colour tones of each BCC and known calculations; (2) the CCBs, with the exception of white and black, are arranged in ascending order of shade to obtain a set of "standard" chromatic components (SCCs) which are graphically positioned according to the co-ordinates a, b thereof; (3) the "effective" chromatic components (ECCs) forming the outer boundary of the polygon with the largest surface area are chosen from said SCCs; (4) the boundary of an "effective" volume sector (EVS) is determined in the ECS and for each pair, i.e. "effective pair" (EP), of ECCs which are immediately adjacent on the graphic line (1, 3) and taken together with black (B) and white (W), said EVS being the one to which said EP corresponds; (4) each EVS is fractionated according to the average allowable overall operational colour difference ( DELTA  E) for the industrial application under consideration; and (5) a reference (L, C, H) is assigned to each resulting EVS fraction, whereby the set of EVS fractions thus defined and identified forms the desired shade chart.
