Patent IT-1191027-B (IT)
Title: Cement prepn. additive
Inventor: COLLEPARDI MARIO
IPC: C04B/
Filed: 1982-10-08
Granted: 1988-02-24
Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Title: Metallurgical furnace coupling plate mfr.
Inventor: GRIGORIEVICH IOSHPA VLADIMIR
IPC: F27B/
Filed: 1982-03-26
Granted: 1989-11-30
Abstract: Cast iron cooling plates for metallurgical furnaces contg. cooling tubes with a different coefft. of expansion from the cast iron are produced by dividing the mould by two partitions near the inlet and outlet connections for the tubes in three parts. The partitions are formed by compensating spacers (asbestos) and the centre part is cast first. After it has cooled down to the ambient temp. the two end sections are cast. This eliminates casting stresses in the tubes and prevents their carburisation (due to the shorter time of contact with the hot cast iron). Thermal stresses arising in operation have less effect, and the life of the cooling plates is longer.

Title: Removing deformed capsules from stream passing down tube
Inventor: WOOD REX C
IPC: B07B/
Filed: 1981-12-22
Granted: 1989-11-22
Abstract: Misaligned or deformed capsules are removed from a stream of capsules which are advanced successively through a tube. At the upstream end of the tube is a plate with a gauging aperture through which the capsules normally pass. Deformed capsules do not pass through the aperture and are retained by the plate. A retained deformed capsule is dislodged from the plate by pivoting it to move the capsule adjacent an air jet which blows upstream. A detector at the downstream end of the capsule tube detects a blockage of the gauging aperture by the absence of capsules being discharged from the tube. The appts. detects and removes deformed capsules and prevents their blocking subsequent processing stations. The capsule removal is automatic and processes 2500 capsules per min.
