Patent FR-2327348-A1 (FR)
Title: Appts. for liquid treatment e.g. dyeing of textile loop - has a first chamber from which loop is advanced to second chamber on perforated roll
Inventor: LEJEUNE ALFRED
IPC: D06B3/28
Filed: 1975-10-06
Abstract: Appts. includes a descending duct connecting at its lower end into a first chamber (I). The textile advances into (I) via the duct into which treatment fluid is fed. The textile is advanced out of (I) by a feed roll situated above it, and fed into a second chamber in which a rotating perforated roll is located.

Title: Triac with high speed voltage change during switching - has grooves formed on conductive surfaces filled with insulating material to prevent lateral current flow
Inventor: LOCQUENEUX RENE
IPC: H01L29/747
Filed: 1975-12-24
Abstract: The triac consists of top layer (fig. 4B) comprising triangular P and N zones with N and P zones doped into adjacent corners of the triangles: ang a bottom layer (fig. 4C) the mirror image of the top layer but without the doped corner zones. The two layers are separated by an N-type layer (N2) as in prior art structures. A groove (shaded area) is provided between the two triangles in both the top and bottom layers. These two grooves are formed by chemical etching and are filled with a passive material. The grooves extend into the central N-type layer (N2) and effectively form a barrier between the two lateral halves of the structure -- ie the currents are constrained to follow a given curve.

Title: Large engine cooling system - has cooling tower with natural draught augmented using engine exhaust gas flow
Inventor: HELLER LASZLO
IPC: F02C7/14
Filed: 1976-01-08
Abstract: Large engines are cooled using a natural draught cooling tower, the media being cooled passing through a heat exchanger (26). The draught in the tower is assisted using engine exhaust gases which are mixed with the heated cooling air. Thus, the cooling effect produced by the tower can be modified by regulating the engine exhaust gas flow to it. The exhaust gas is fed into the base of the cooling tower by pipes which have distribution orifices directed towards the tower centre. The pipes (29) are placed just radially inward of the heat exchanger and receive the exhaust gas via an underground duct (30).

Title: Grading machine for carrots - has bars on belts passing over rollers with radial increase of gap between bars releasing trapped carrots
IPC: B07B13/04
Filed: 1976-03-18
Abstract: The machine is used to grade carrots according to thier diameter, the vegetables falling through the gaps between tubular bars attached to a belt at each end. The endless loop formed is positioned over a pair of rollers, the lower section hanging loose. The ungraded carrots are placed on the belt, those passing through being removed through the front of the machine. As the belt (3) passes over the end rollers (5). The radial effect progressively opens the gap (A) between the bars (12-16). This enables any carrots trapped or pinched between the bars to be released (B) automatically at the sides of the machine without damage.

Title: Cellulosic sheathing with metallic flake colouring - made using an alkaline suspension of the colourant(s)
IPC: A22C13/00
Filed: 1976-09-03
Abstract: In mfr. of wet shrink fibrous sheathing, the sheathing compsn. is deposited from alkaline dispersion incorporating 5 pts. pigment per 100 pts. solid coating material. The pigment comprises metallic lamellae to provide a pearl finish when solidified. Method is esp. for making covers pigmented to give a shining finish of copper or silver, e.g. for tubular packaging for enclosing foodstuffs such as sausage meat, flavour sauces, etc. or for materials such as toothpaste and face cream. Direct blending in alkaline solution avoids the complication of adding the pigment by means of an independently applied pigmented gel coat. The gloss measurement technique is insensitive to shade variations imposed by the supplementary colourants.

Title: Non:return valve actuating mechanism - has balance passage with control valve leading to remote part of system
IPC: F16K15/00
Filed: 1976-10-14
Abstract: The actuating mechanism is for a non-return valve in a feed water system, has a plunber movable lengthwise between the open and shut positions. Under normal flow conditions a number of forces act on the plunger holding it in an intermediate position. A balance passage connects an internal portion of the valve to a more remote part of the system, so as to generate a further force acting on the plunger so as to hold it open. There is a valve in this passage, to allow reduction of the extra force concerned, and thus move the plunger from the desired open position to the intermediate one.

Title: Slave mechanism for hydraulic transmission of excavator - has lock preventing reversal unless pump control attains specified position
IPC: B60W30/18
Filed: 1978-01-13
Abstract: The slave unit is designed for incorporation in the controls of an hydrostatic transmission, utilising a lever(15) in selecting the sense of rotation. A spring(14) or hydraulic pressure acts in the direction of the switch and on a distributor inverter(8), with the evvect that a locking mechanism(17) prevents switching unless a pump control(10) has attained a predetermined position. The latter position depends on the pressure in the relevant feed(9), and the transmission is of a type having a two-way reversible variable discharge pump. The hydraulic pump control automatically returns to a zero discharge position, being activated bi-laterally by a control distributor.
