Title: Electronic patterning device for loom - having reversing circuit to facilitate un:weaving of complex patterns
Inventor: TZVETKOV KRUM KOSTOV
IPC: G05B19/07
Filed: 1982-05-12
Abstract: An electronic patterning device for a loom, using counters which control the weaving sequence by counting the number of picks of each type of weft during insertion, and are reset when the weft is changed, has a reversing circuit which operates during unweaving operations to control the unweaving of complex patterns. The reversing circuit is connected through a feed-back loop to the pattern-control circuit, and to a transducer on the loom crankshaft. It comprises an inverting switch, logic circuits, a flip-flop and a rectangular-wave generator which controls the count-down of the counters during unweaving. This arrangement eliminates complications arising from weft-changes during reverse-counting, and provides problem-free unweaving of complex designs. /2.

Patent FR-2563119-A1 (FR)
Inventor: MORIN JEAN-XAVIER
IPC: C10J3/48
Filed: 1984-04-20
Abstract: A process for circulating solid particles within a fluidization chamber, in which is formed a circulating fluidized bed comprising a dense lower zone (A) with a high concentration of particles, above which is located a dilute zone (B) containing particles carried along by the rising stream of a gas towards the upper part of the chamber (1), the latter opening into a circuit (4) for discharging the gases and particles, incorporating a device (41) for recovering the particles carried along, which is connected to the chamber (1) by means of a circuit (45) for recycling the recovered particles. In the upper part (12) of the fluidization chamber, the circulation speed of the cases is reduced before their discharge, so as to produce above the dilute zone (B) an upper zone (C) with a higher concentration of particles, in which some (35) of the particles escape from the stream of gas and fall in a shower along the side wall of the chamber, at the same time forming a descending annular film (34). The improved fluidization chamber for carrying out the process applies particularly to the combustion and/or gasification of combustible material.

Title: Teaching medium for displaying, simulating and embodying the Gauss law
IPC: G09B23/18
Filed: 1984-06-13
Abstract: Device for displaying, simulating and embodying the Gauss law. It is constituted by a parallelepiped receptacle equipped with a sliding upper face pierced at its centre. The front face comprises two slides in which there slide perpendicularly two indices and a vertical reference mark physically representing its middle. When the user pours in a granular material, or beads, after a minimum layer has been deposited, the appearance of a bell-shaped curve representative of the Gauss law is observed. The profile of the layer takes the form of a bell-shaped curve which remains of constant shape whatever the height of the layer. If the upper sliding face is moved slightly around the middle, the shape remains the same. If the quantity changes, the law does not change. The device according to the invention is particularly intended for a physical representation of the Gauss law, in order to aid understanding by students and pupils in technical schools and polytechnics.

Title: Process for manufacturing guides for fringing (edging), shaping and tuck-forming, by moulding as a single piece
IPC: B29C33/52
Filed: 1984-09-11
Abstract: The invention relates to a manufacturing process making it possible to produce, simply, effectively and rapidly, guides as a single piece which are intended for making a tuck for flat or tubular edge-pieces (flanges), which are reinforced or otherwise, of covers, sleeves, etc. This is carried out using textile fabric, plastic, non-woven, paper, coagulate-containing or PVC- or polyurethane-coated materials which are precut into parallel-sided strips. The process according to the invention consists of a treatment of the core to be moulded so that the latter, despite complex and multiple lines of counter-draught, can be extracted from the mould after its polymerisation, the latter, thus freed from the core, being transformed into a shaping guide or die. The process according to the invention is characterised in that the core, in its entirety, is formed with a flexible material corresponding to the dimensions (thickness, width) of the base strip, having, at one end, the rectangular profile of the strip to be treated and, at the other end, the final profile of the treated edge-piece (flange) which is to serve for carrying out the moulding of the guide.
