Title: Paracasein and whey separation system - combines suction decanting with tipping over filter grid in flow line
IPC: B65G65/23
Filed: 1974-11-08
Abstract: Paracasein is sepd. from whey in chees manufacture by removing most of the whey from the tank with coagulated milk by suction, followed by tipping the tank contents over an inclined chute and a filter grid which passes only the residual whey. The paracasein which flows over the grid is sepd. into smaller containers.

Patent FR-2272466-A1 (FR)
IPC: G06F11/10
Filed: 1974-12-27
Abstract: A semiconductor memory includes means for separating the causes of error affecting the addressing and recording of information bits from those affecting check, or parity, bits. The recording words comprise 16 information bits, and are divided into two "bytes", of eight bits each. Each byte is provided with its own check bit; and two half-words of nine bits are recorded at the same address. Each submodule of the memory comprises two printed-circuit cards. The first card supports the integrated memory units wherein, for each word, the information bits of the first byte and the check bit of the second byte are recorded; the second card supports the memory units wherein the information bits of the second byte and the check bit of the first byte are recorded. Since an error cause affecting the control or the addressing circuits mounted on a card does not affect the recording and the addressing circuits of the second card, the recording or addressing of the information bits on one card will differ from the recording and addressing of the related check bit on the other card. Both bytes may be written or read out separately; and the writing or the reading-out signals of the information bits are independent from the writing or reading-out signal of the related check bits for both cards.

Title: Psychoneurograph stimulation response measuring apparatus - gives complementary stimulation at given time before or after one to be measured
IPC: A61B5/16
Filed: 1975-04-28
Abstract: The appts. measures the response of a patient to a sensory stimulation. At a given time before or after the stimulation to be measured, another complementary stimulation is given, causing a visible, foreseeable and recordable reaction. This complementary stimulation can be a sound, a light, a puff or air or heat, or an electrica or mechanical shock, as can the one to be measured, and the stimulations can be adjustable for amplitude, frequency, intensity and duration. A first circuit can apply the measure stimulation, such as an audible signal, and a second one the complementary one, such as a flash of light, in a selected order, until the conditioned reflex is acquired. The complementary stimulation is then no longer necessary to provoke a visible reaction.
