Title: Process for preparing low earing aluminum alloy strip on strip casting machine
IPC: C22F1/04
Filed: 1979-07-27
Abstract: The present invention teaches a multi-stepped process for preparing high strength, improved formability, low earing strip stock which is especially suitable for the manufacture of deep drawn and ironed hollow bodies such as cans or the like. The process of the present invention is carried out in two distinct operations. The first operation comprises continuously casting an aluminum melt into strip form on a strip casting machine so as to produce a desired dendritic arm spacing, hot rolling the continuously cast strip at casting speed in a temperature range between 300 DEG C. and the non-equilibrium solidus temperature of the alloy with the total reduction in excess of 70% and finally coiling the hot strip and allowing it to cool in air to room temperature so as to produce a metal strip having properties favorable for subsequent cold rolling operations. The second operation comprises an improved cold rolling operation in which a brief heat treatment at 350 DEG C. to 500 DEG C. for not more than 90 seconds is introduced between a first and second cold rolling operation.

Patent ES-8200198-A1 (ES)
Title: Data receiver including means for forming line samples and method of operating such a data receiver.
IPC: H04L7/02
Filed: 1980-09-12
Abstract: In a multipoint data communication system using quadrature-amplitude modulation, a master modem (20) and a plurality of tributary modems (11a, 11b . . . 11n) are interconnected via respective transmission channels (13a, 13b . . . 13n, 16). Adaptive equalizer circuitry (55, 56) in the master modem equalizes the channel from a particular tributary by multiplying samples of signals received from the tributary by an ensemble of tap coefficients associated with the tributary. The tap coefficient ensembles for each tributary are stored in a memory (91) from which they are retrieved at the start of transmission from that tributary. Timing-acquisition circuitry (29) within the master modem adjusts the phase of the latter's sampling circuitry (23, 27) at the start of transmission from a given tributary so that the received signals are sampled at the correct time points. In particular, a timing acquisition signal having spectral components only within the non-rolloff region of the equalized baseband-equivalent transfer function is transmitted by the tributary. The master samples and equalizes the received timing acquisition signal to form a succession of timing acquisiton equalizer outputs. The time by which the operation of the sampling circuitry is to be advanced or retarded is determined as a trigonometric function of two successive ones of the timing acquisition equalizer outputs. The timing acquisition signal is illustratively a double-dotting pattern having a four-symbol-interval period. That period is integrally related to the carrier frequency. This allows the samples needed in order to begin forming the timing acquisition equalizer outputs to be generated by replicating the samples taken over only four symbol intervals.

Title: Radiator
IPC: F28F9/18
Filed: 1982-03-05
Abstract: In a radiator having flat tubes arranged in parallel and connected to header pipes for feed and return flow, each flat tube has two connection bores near the front end thereof.
