Title: Polyester plaster mouldings include coloured veins - by using displacement flow to envelop local deposits of coloured material on the cavity surfaces
Inventor: BOUFFIER PATRICK
IPC: B28B1/00
Filed: 1988-02-23
Abstract: Moulded profiles which simulate marble are made by (a) coating parts of the walls and base of a cavity mould with a colourant consistent with the veins of natural marble, pref.  as a welded blend with particles of plaster for adherance to the walls; (b) pouring into the base of the mould to about 10% of its capacity, a quantity of plaster tinted to the required background colour, after which (c) the cavity is almost filled with a block of a harder plastic compsn.  The block is then pressed under sufficient force to cause the initial charge to be displaced sufficiently to fill the gaps between the hard core and the mould walls, enveloping the contrasting material without significant displacement.  The plasters may be modified with or based on polyester resin. USE/ADVANTAGE - A relatively simple process to produce solid blocks while restricting the use of colourants to the superficial zones.

Title: Differential coder with auto-adaptive predictor filter, with rapid gain adaption, and corresponding decoder
Inventor: FREDERIC ZURCHER
IPC: H03M3/04
Filed: 1990-07-03
Abstract: The invention relates to a differential coder with auto-adaptive predictor filter. The coder comprises a comparator (12) and a prediction loop including an auto-adaptive predictor filter (14) with several channels, an automatic gain circuit (16) and a multiplexer (18). The circuit (16) allows the gain to be adapted on the basis of k+1 successive values DELTA (n-k) to DELTA (n) according to the law: if G(n), current value of gain > GC(n-1), previous value of the peak gain, then: GC(n) = f .G(n) if G(n) <= GC(n-1), f = dispersion coefficient, or else GC(n) = G(n) if G(n) > GC(n-1). For each pair of successive values DELTA (n-(j-1)), DELTA (n-j), a state variable is defined with pj = 2k - jJ if DELTA (n-(j-1)) = DELTA (n-j), or otherwise pj = 0, and delta (C DELTA (n)) coefficients are defined with delta C( DELTA n) k - 1 delta C( DELTA n) > 1 if 2k - 1 <= C DELTA (n) k. The current value of the gain G(n) satisfies the relationship G(n) = delta (C DELTA (n)) x G(n-1) if the calculated value of G(n) is greater than a reference value u x GC(n). Application to speech coding/decoding in telephony.
