Patent FR-2350123-A1 (FR)
Title: Two stage liquid film evaporator - with centrifugal dispersion of fluid in each stage
IPC: B01J10/02
Filed: 1976-05-04
Abstract: A vertical evaporator is equipped with means for introduction of dispersed fluid throughout the heat transfer area. Any number of dispersion and evaporation stages may be employed and the device described uses two stages. For concentration or distillation of temperature sensitive products and for chemical reactions in the manufacture of intermediates for plastics, microbiological and pharmaceutical products. Evaporation occurs at maximum rate at the point at which droplets impinge on the heat transfer surface, therefore rather than introduce the liquid at the top of the heated wall and let it fall in a film, the rotor distributes droplets throughout the wall area. The vapour stream has to pass through the rotor in order to escape, hence any entrained droplets are extracted centrifugally from the vapour at this stage.

Title: Creping textile web by passage through nip - having one surface with recesses to allow the web to thicken and reduce its density
IPC: B31F1/16
Filed: 1977-01-31
Abstract: A textile web is creped by passage through a nip between two moving surfaces, one of which is elastic. One of the surfaces has recess so that as the webs relaxes on passage through the nip it expands into the cavities to form regions of the film which are thicker and of lower density. The method may be used with paper, cardboard, knitted, woven or non-woven fabrics. Conventional creping processes merely deform the film and corrugated. The present process produces a new creping effect because of the expansion to produce thicker low density regions.

Patent FR-2358700-A1 (FR)
Inventor: DOMBROWSKI FERDINAND
IPC: G05D23/19
Filed: 1977-05-31
Abstract: A charge controller of an off-peak storage heater supplies the AC pulse sequences, which are to be monitored, with empty spaces via the connection (Mp, 26) to the control device. Across the poles (6, 7) there is a control voltage, a time-dependent signal which defines the monitoring period of the charging/discharging cycle of the storage heater. The display device (53) is controlled as a function of the charging/discharging state of the capacitor (37). The charging/discharging process is controlled either by the two-stage amplifier (13, 17) or by the transistor (9). During the monitoring period, the glow lamp (5) is not illuminated and the high-impedence photoresistor (3) switches the transistor (9) off. In this case, the amplifier (13, 17) controls the charging/discharging process of the capacitor (37). At the same time, the first stage (17) of the amplifier has the AC voltage pulse sequences applied to it by means of the diodes (24, 28) in such a manner that the pulses of the one polarity supply the operating voltage and those of the other polarity supply the voltage to a control electrode of this stage (17). The transistor (13) remains switched on and prevents the display device (53) responding as long as there are a sufficient number of AC voltage pulse sequences with uniformly distributed positive and negative voltage elements.
