Patent FR-2215411-A1 (FR)
Title: Amine salts, esp. nylon-6,6 salts, prodn. - economically and avoiding decompsn. by pptg. the salt from an aq. soln.
IPC: C07C51/41
Filed: 1974-01-24
Abstract: Solid, water-sol. salts of a diamine and a dicarboxylic acid, esp. Nylon-6,6 salts, are economically produced with little decompsn. by adding the diamine to an aqs. soln. of the salt and sepg. the solid salt pptd. Little decomposition occurs as no distillation takes place and hence the high temps. are not encountered which tend to decompose the salt.

Title: Fatigue testing of small cross section wires - involves rotational flexing of sample retained by gluing ends to clamps
Inventor: COQUILLET BERNARD
IPC: G01N3/34
Filed: 1975-12-31
Abstract: Rotational flexing fatigue of small cross section wires such as those used for springs are tested on a machine which overcomes problems such as premature rupture due to the clamping method. A test sample (6) is placed between two identical tubular units (4, 5) mounted on pivots (18, 19). The sample is held by gluing the ends into tubular rings and retained in hollow spindles (29) by clamping nuts (31). The sample is rotated by a variable speed electric motor (7) and at the required speed a lever (45) is operated causing a cam (44) to disengage from a weight platform (40). The tubular units pivot under the weight to present a flexing strain to the sample.
Patent FR-2337862-A1 (FR)
Title: Continuous drying of granular material - using a fluidised bed with zones of decreasing slope each independently supplied with drying air
IPC: F26B3/08
Filed: 1976-01-08
Abstract: The drying takes place in several successive zones, each zone after the first has its bed support palte through which the drying air passes at a shallower angle than the preceding one. The first zone may be at 40 degrees to the horizontal and the fourth zone at 20 degrees, with the slope of intermediate zones reducing gradually. Each zone is also supplied with its own supply of heated drying air independently controlled. For drying at high temps., above 250 degrees C, an alternative design of equipment is preferred which uses steps in each zone instead of sloping plates. The steps in successive zones are shallower and independently controlled heating air is still supplied to each zone. The different zones allow for control of the flow and depth of material. It is also possible to vary the fluidisation air flow and press, to each zone. The result is bed depths not exceeding 10 cm. compared with 20-80 cm using other fluid bed driers. The separate control of drying air-press. and flow for each zone helps to control the flow of dry material as a function of its moisture content.

Title: Digital data transmission method - uses phase modulation of carrier wave and removes ambiguity arising from phase reference of carrier
Inventor: LIGER MARC RENE
IPC: H04L27/20
Filed: 1976-01-23
Abstract: The method of digital signal transmission uses phase modulation of a carrier wave. The digital signal is split up into a series of q binary elements. These correspond to each of n = 2q levels which can be taken by a series of q elements with state of phase xi of a carrier wave. The n state of phase x1......xn are chosen with respective appearance probabilities of P1....Pn for at least one of the sums (between i = 1 and i = n) Pi cos xi and Pisinxi not equal to zero. When all the probabilities P1....Pn are equal x1 and xn are separated by 4 (pi)/(n+1), and xi and xi+1 are separated by 2(pi)/(n+1).

Title: Lightweight reinforcing ring for dust extractor hose - made of e.g. welded drawn metal tube
IPC: B01D46/06
Filed: 1976-04-28
Abstract: The ring is mfd. from e.g. a welded drawn metal tube, or from cellular or fritted metal to reduce the wt. in relation to a drawn wire. by 40-70 % according to the size of the wire or tube useD. By reducing the wt. of the rings, they have less tendency to wear out the fabric of which the hose is made or the stitching threads which hold the rings in position, on vibration of the hose. Compared with plastic rings, they have greater rigidity at the temp. of the filtered gases which arise, and are not subject to chemical attack or premature ageing, e.g. after one year, with the associated tendency to become brittle.
