Patent FR-2183535-A1 (FR)
Title: Continuous powder coating machine for sausages - in which sausages are freely suspended in powder-filled atmos
IPC: A23P20/12
Filed: 1972-05-08
Abstract: Machine consists of a box in the shape of an inverted pyramid. Guide rails are provided in the upper portion in which the ends of carrier stems can slide; bonds, attached to the stems, carry the sausages and allow them to swing freely in the box. The lower part of the latter has a beater which projects the powder to the inside of the box in which the sausages are circulating. As the sausages progress they strike a fixed plate which removes any excess powder; this travels to the bottom of the box where it is filtered and rejoins the powder being projected by the beater. Other nonedible articles of a similar shape for decoration and ornamentation can be coated with pulverulent materials in the same way.

Title: Treating refinery sludges - by two-stage extraction to recover wax and oil
IPC: C10G73/36
Filed: 1972-11-20
Abstract: Refinery sludge is deoiled, dewatered and dewaxed by (1) mixing the sludge with a light aliphatic hydrocarbon (pref. a 3-5C alkane), separating the mixt. into water of reduced COD, water-waxy solids slurry and an oil-aliphatic hydrocarbon phase, heating the latter phase to above the critical temp. of the aliphatic hydrocarbon under a pressure to keep the aliphatic hydrocarbon in a dense phase so splitting the oil-aliphatic hydrocarbon phase into aliphatic hydrocarbon and oil portions which are recovered, and (2) separating water from the water-waxy solids slurry, mixing the waxy solids with a light aromatic hydrocarbon (e.g. benzene or cumene), separating the resultant mixt. into wax-free solids, and a wax-aromatic hydrocarbon phase and recovering wax from the latter phase. The wax-free solids may be used as land fill, the recovered wax can be decoulourised, and the oil recovered in step (1) is clean and suitable for feeding to a cat cracker or for blending with fuel oil.

Title: Sedimentation appts. for waste water and sewage - with internal sludge recovery section
IPC: B01D21/02
Filed: 1973-06-26
Abstract: Sedimentation appts., for waste water and sewage, is included in an oxidn. tank. The inlet pipe grazes the surface of the tank and brings the effluent to the point where its speed is at the max., so that its motive force can be used for its circulation. The sludge recovery section consists of an upper partition provided with baffles through which the clear water rises into the settlement portion while the sludge falls to the bottom. The baffles are arranged in series and each consists of two longitudinal shutters in the form of a 'V'. The current of liq., entering the recovery section, produces a zone of reduced press., between the arms of the 'V', which tends to draw the sludge towards the base and prevents any floating particles from rising into the settlement section. The end of the recovery section opens into the oxidation tank and any non-settled matter is re-introduced into the circulation induced by the in-coming liq. passing from (5) to (14). A pipe evacuates the clarified water, freed from sludge. As compared with conventional tanks, the dimensions of the appts. can be reduced and an improved yield obtd. There is no need for the usual system of removing floating matter from the surface of the clarifying section.

Title: Quenching long steel shafts without distortion - using induction heating coil mounted above quenching tank
IPC: C21D1/42
Filed: 1973-09-05
Abstract: Parts with a large length:dia. ratio and a thickness which is not constant along the length, are located vertically in a guide-tube made of a refractory insulating material, the guide-tube being mounted over a bath of oil and surrounded by a mutli-turn induction coil of suitable consign. which is connected to a generator. The bottom of the guide-tube is closed by a sliding refractory plate which is an insulant and has a polished surface; at the end of the heating cycle the plate is automatically removed so the part can fall into the oil-bath.

Title: Propulsion aid for a swimmer - has pedal operated fish tail form joined to swimmer by harness
IPC: A63B35/02
Filed: 1974-03-29
Abstract: The swimming aid is attached to a body harness and oscillated w.r.t. a vertical axis by foot levers, thus propelling swimmer forwards. The harness locates the tail between the swimmers feet, extending beyond the feet and with major tail faces in a vertical plane if the swimmer is lying on his back in the water. Longitudinal straps pass over the swimmer's shoulders and are attached to a belt at the waist. A bar passing through the flexible blade type tail has foot stirrups attached to pedals so the swimmer, by bending and straightening alternate legs, effects tail oscillation and proceeds through the water using his hands for steering.

Title: Cinematographic depth of field calculator - gives field depth for several predetermined valves of diffusion circles
IPC: G02B7/28
Filed: 1974-06-20
Abstract: The field depth calculator has one or several distance scales for use with one or several different objectives classes, for example fixed focal objectives and variable focal objectives; a focal scale (20) associated with a diaphragm scale (21) and an index system (23, 24) designed so that the two latter scales, after being adjusted with respect to each other, coincide the focal value of the objective used with the chosen diaphragm opening. It is then sufficient to bring an index opposite the focal distance in order to read on the distance scales, opposite the two other indexes, the field depth (for a given diffusion circle) corresponding to the class and the objective focal length, as well as the chosen diaphragm opening.
Patent FR-2276597-A1 (FR)
Title: Precise measurement of sonar bearing angle - obtained by determining error in difference signal from two hydrophones
Inventor: DEBART HUBERT
IPC: G01S3/808
Filed: 1974-06-27
Abstract: A sonar source bearing is detected by hydrophones whose distance apart is known. Knowing the speed of the sonar wave in the transmission medium enables determination of the bearing from the difference in arrival of the sonar wave. Measurement of error in this difference enables a precise bearing to be obtained. Two hydrophone detectors arelocated a known distance apart. Their outputs feed into matching circuits containing sampling circuits driven in phase by a clock circuit. The matching circuit outputs pass into delay circuits one of which is adjustable. These are multiplied with additional delay circuit outputs and integrated. The integrator outputs are subtracted and divided to obtain the signal ratio which is then multiplied by a delay circuit output to produce input signal delay error and thus tolerance on the bearing angle.

Title: Powdered lactoprotein prodn. - by heating, acidifying and stirring milk serum, sepn., washing and drying
Inventor: EMERIAULT MARC MAXIME ALPHONSE
IPC: A23J1/20
Filed: 1975-02-25
Abstract: Powdered lactoproteins are obtd. from milk serum by flocculation, separation, washing and drying. Flocculation is carried out by heating, acidifying and stirring separation is carried out in a horizontal centrifuge. The concentration of lactoproteins before drying must be is not 18%. They are then dried using a double fluidised bed in two stages, the first being used to granulate and the second being used after milking of the dry granules produced in the first stage. The fine particles produced by milking are pref. recovered using a cyclone. Before heating, the serum must have a pH is not 1.4, otherwise it must be acidified to pH 6.5-8.5. The lower the initial pH, the higher the final pH must be; e.g. initial 4.5 final 8.3; initial 4.0 final 7.2. Heating is e.g. to 88-98 degrees C pref. 94 degrees C and acidification gives a final pH of 4.5-5.0.

Title: Display structure giving illusion of lightness - using framework formed by logarithmic spirals on spherical surface
IPC: E04B1/32
Filed: 1975-05-06
Abstract: The centre lines of the tubular members formings the display structure are defined in the following way. A number of equally spaced meridians are drawn from the pole of a sphere. A logarithmic spiral intersects each meridian at a point at a constant acute angle alpha. Two families of such curves are drawn, one family inclined in each direction so that two spirals intersect at each point at an angle of 2 alpha. The spherical surface is thus divided into quadrilaterals by the spirals, which diminish in size from the equator to the pole giving an illusion of height and lightness. Other shapes can be formed by using parts of the meridian lines.
