Patent FR-2261490-A1 (FR)
Title: Air conditioning equipment for product drying - sucks in humid air in housing via products before evaporation
IPC: F24F3/153
Filed: 1974-02-18
Abstract: Humid air is sucked in by the equipment via the products to be dried to filter it, both equipment and products being accommodated in a closed housing. It is dried by evaporation and then reheated by the calories released by a condenser, so as to maintain a controlled temperature inside the housing. Drying can be effected by condensation of water particles on an evaporator, comprising a finned tube inside which an expanded coolant circulates. The water droplets can be collected in a gutter also allowing ascending air flow to a centrifugal fan (10) at the top of the equipment (A). There can be a thermostat mounted inside the housing or equipment allowing circulation of calories released when the vapour from the compressed coolant is liquefied.

Title: Rapid construction system for house - has protecting sheet placed over rafters on verticals before wall construction
IPC: E04B1/00
Filed: 1974-04-23
Abstract: A house with a conventional external appearance is constructed by erecting a set of vertical posts (2) embedded in the foundation (3) and interconnecting them with longitudinals (4) and then erecting the triangular roof supports (5) above them, made up of wooden rafters followed by diagonals (9) between the triangles to form a rigid frame. This can then be covered by a plastics sheet to protect the whole area from the weather. Walls can then be erected underneath, made up of panels (11, 12, 13, 14) which can include fibre glass slabs, expanded foam slabs and finishing layers as well as load carrying panels, and ceiling sheets (18) added, followed by insulation layers above them. Thus an unobstructed space is formed underneath which can be divided up as required.

Title: Physiological liquid circulation investigation appts - releases impulses when signal derivative is zero
Inventor: MILLERET RENE
IPC: G01P5/24
Filed: 1975-01-10
Abstract: The apparatus investigates the circulation of a physiological liquid utilising the Doppler effect and having a transducer connected to the transmission and receiving circuits. At each period of the signal examined an impulse of set amplitude and duration is emitted, and the impulses are integrated so that the mean value of signal obtained is proportional to the frequency of the incident signal. Means are provided for detecting when the signal derivative falls to zero, the impulses being released when this occurs. There can be two similar paths, 90 deg. out of phase with each other, indicating frequency change, and phase of the two rectangular signals from each of the paths being recovered by a double bistable master-valve unit.

Title: Continuous control process for flocculation plant - using turbidimeter with a rotary polarising filter
Inventor: SIBONY JACQUES
IPC: C02F1/52
Filed: 1975-01-28
Abstract: Continuous control process for the operation of a plant for the flocculation of a liq. to be clarified consists in using a turbidimeter with a rotary polarising filter; this allows the determn., at any moment and notably at the start of the treatment, of the amt. of colloids in the liq. which have not been affected by the flocculation treatment. The turbidimeter is linked to an alarm system which operates when the colloidal turbidity attains a given value; it is also linked to an automatic regulating device for the dosing pump of the flocculant. When the value of the colloidal turbidity increases beyond an admissible max., the output of flocculant is modified accordingly. The process can be used for the constant supervision of the flocculation from the start to see whether all the colloidal particles are in fact flocculated. In addition, the rate of the flocculant addition can be adjusted continuously to ensure that all the colloids in the liq. are flocculated. The process and device can be adapted for regulating the flocculation treatment not only by adjusting the rate of addition of the flocculant, but also by controlling the amt. of dissolved oxygen in a biological treatment or of the pH of the medium.

Title: Microscopic observation using colour television - has high resolution and definition using series of narrow bandwidth monochromatic spectra
IPC: H04N11/00
Filed: 1975-07-24
Abstract: Microscopic observation of an object is performed using simplified television techniques. High power resolution and high definition are obtained using a seies of monochromatic light spectra of narrow bandwidth in a rapid sequence. These are synchronised for display. A number of spectra of monochromatic light are obtained from a source of white light by rotating a disc in front of it containing colour filters of narrow bandwidth spaced around the disc. The filters are exposed to the light in successive synchronism with the frequency of the images and part images so that each of the narrow bandwidth spectra are produced with a given part image. The monochromator producing the light also produces synchronisation signals for the monochromator in the display and recording equipment.

Title: Composting garden waste - in partially closed containers using additives contg saprophytic bacteria and absorbent materials
IPC: C05F11/00
Filed: 1975-08-19
Abstract: In a process for composing compost material (e.g. grass cuttings) with the aid of a composting additive contg. a source of saprophytic bacteria, a source of nutrients for the bacteria, and a nitrogen source, the composting is carried out in a partially closed container (e.g. a plastic sack) and the additive contains an absorbent material (e.g. cork powder). A composting additive for use in this process and contg. a source of saprophytic bacteria, a source of nutrients for the bacteria, a nitrogen source, and an absorbent material is claimed. The absorbent material absorbs liq. decompsn. prods. from the compost, ensuring that valuable plant nutrients are not leached away and that a foul-smelling compost is not produced as a result of incomplete decompsn. of the material to be composted. The partially closed container keeps heat loss to a min.

Title: Ioniser for atmosphere purification - emits ions from flame of metal burner wired to rectified high tension supply
IPC: A61L9/22
Filed: 1976-01-28
Abstract: The ions are emitted by the flame from a metal burner which is wired to one output terminal of a rectifier supplied with electric current at several hundred to several thousand volts. This high tension supply is derived from a transformer fed from the mains, e.g., 220 volts A.C. The burner is mounted on a plastic base contg. the transformer, a multi-diode rectifier and, if desired, a voltage divider control. A plastic cowl fits around the burner obscuring all but its flame from a side view. Fuel for the burner can be town gas, butane, propane, paraffin, petrol etc. If the fuel is supplied in a cylinder, this may be housed in the plastic base. While one output terminal of the rectifier is wired to the metal burner, the other is connected directly to the mains. Used in prodn. of ions to purify the atmos. of dwellings, hospitals, offices, etc. Emission of ions is two to five times as great as corona discharge ioniser of comparable voltage and bulk. There is no prodn. of ozone and oxides of nitrogen as there is with corona discharge ionisers.

Title: Glass plate stacking and lifting machine - has ram operation controlled by feeler detecting vacuum or pressure alterations
IPC: B65G49/06
Filed: 1976-04-23
Abstract: The plate stacking and lifting machine is particularly for handling sheet glass, having one or more ram operated suction cups moving to and from the stack. A feeler releases the impulse controlling ram piston rod movement on touching the stack, whose height varies as items are loaded or removed. The feeler reacts to variations in pressure in the vacuum supply to the cups (8), or in the compressed air supply to the ram (7). When lifting the top plate off the stack (2), the cup can be already connected to the vacuum source, so that when it makes complete contact the sudden increase in vacuum is detected.

Title: Water operated piston and cylinder tilting mechanism - has cylinder chamber connected to oil supply to prevent scale formation
IPC: A47J27/14
Filed: 1976-04-26
Abstract: The piston and cylinder actuator is for tiltinga plate or vessel (B) which may be part of the equipment for a canteen or other heavy duty cooking equipment and is operated by water pressure. A valve (7) is operated to connect the supply (8) to the piston (2) to lift it, then reversed to lower it. The top of the cylinder (3) has an opening (5) for a line (10) connected to an oil tank (11). When the piston is lowered, oil is then drawn into the chamber above the piston by gravity or suction ensuring that the interior is adequately lubricated to prevent scale formation resulting from the water supply.
