Patent FR-2332044-A1 (FR)
Title: Regeneration of an exchanger bed of granular material - using countercurrent to reduce soln. losses to absolute min.
Inventor: BARRAQUE C
IPC: C01B31/08
Filed: 1975-11-19
Abstract: Regeneration of a bed of granular material which has been used for purificn. of a soln., e.g. for recovery of Fe and/or Cr from surface treatment liqs, and which is located at the bottom of a vessel in which the operations of purificn. and regeneration are carried out, is effected by first of all driving out and recovering the residual treatment liq. The material in the bed is next loosened and rehydrated by injecting water, and in a second stage the bed is regenerated by a flow in countercurrent, followed by rinsing with water. During these operations the liqs. are collected at the level of the upper surface of the bed. In a third stage, the liq. to be treated recovered in the first stage is injected, before a new purifying cycle is commenced. All the injections of liq. in the three stages outlined are effected from below upwards. Losses are eliminated involved in co-current processing, and there is no need to neutralise the effluents before they are run into the sewers.

Title: Kicking bag for babies and infants - comprising combined sack and jacket to keep child safe, warm and easily accessible
IPC: A41B13/06
Filed: 1976-01-28
Abstract: A kicking suit for small babies and infants, consists of a sack made in one piece with a jacket upper section opt. having have sleeves. The sleeves are too long for the child's arms so that the ends can be closed over it hands. There is an opening from top to bottom or practically to to the bottom, of the sack, which widens out downwards from the jacket section. This opening can be closed tightly either by a full length sliding clasp fastener or by a row of buttons. Allows the child to be left without risk of harm by rucked up garments interfering with breathing etc. The child is kept warm with the minimum of garments - say, napkin and rubber pants, and is available for examination immediately, as required possibly in clinics, or for changing with min. handling. Laundering work is thus also reduced to the min.

Title: Precision casting mould binder - based on silica organosol diluted with aq. phosphate soln. for increased stability
IPC: B22C1/20
Filed: 1976-02-11
Abstract: A precision casting mould based on refractory aggregates is made using a binder which is prepd. by mixing a silica hydrosol, contg. 3-6% SiO2, with an organic liq., and, after separating, recovering an organosol contg. 16-30% SiO2. The organosol is diluted up to approx. 20 vol.% with water contg. is approx. 4% phosphates. The refractory aggregates are bonded by colloidal silicic acid as well as by a phosphate bond during melting of the metal to be cast. A low cost mould with a strong SiO2 organosol bond is mfrd. The mechanical properties and stability are improved. Conventional appts. is used in the prepdn. of the organosol and the mould. It is not necessary to supply any energy nor is there any evolution of pollutants. The sols. are compatible with all the usual refractory materials used in precision casting moulds. Heavier parts can also be cast.

Title: Upgrading pile coated fabrics - by thermal deformation of the hair coating on a more heat resistant canvas base
Inventor: TYBERGHEIN MARIE-LOUISE
IPC: D06C23/04
Filed: 1976-07-22
Abstract: Upgrading of hairy fabrics, i.e. fabrics with a long- or short-hair pile, comprises (a) starting from a hairy woven fabric of generally known type, e.g. that used for fabricating an artificial fur and consisting of canvas with a hair coating and of material selected so that the hair undergoes permanent deformation under the action of heat while the heat-resistance of the canvas is considerably greater than that of the hair, (b) exposing the canvas to the simultaneous action of heat and pressure along a pattern consisting of straight line sections, as a result of which the parts of the hair covering so affected are deformed and the generally desired design consisting of wide or narrow elements in the hair covering is formed, whereby its external aspect of the fabric on the side of the hair covering is favourably modified, i.e. upgraded and improved. The improvement of the artificial fur fabric can be achieved without the need to introduce a foreign body or material.

Title: Anodising aluminium for bonding with polymer adhesives - is carried out in phosphoric acid bath at 10-30 degrees C
Inventor: MARCEAU J ARTHUR
IPC: C25D11/08
Filed: 1977-02-22
Abstract: Porous aluminium oxide layers are formed by anodising the article in a bath contg. 1.5-50 wt.% (10-12) wt.% H3PO4 at 10-30 (21-24) degrees C, and using an anodising voltage of 1.50-50 (10-15) volts. Pref. the anodising process is carried out for 10-30 (20-25) mins., and the article is rinsed within 0.3-2.3 mins. after anodising is completed. The process is useful for pretreating aluminium articles which are to be bonded with polymeric adhesives such as epoxy adhesives, e.g. in aircraft manufacture. The porous aluminium oxide layer formed is compatible with polymeric adhesives and gives high bond strengths. The resulting adhesive bonds have high resistance to hydrolysis and failure of the bond is generally by cohesive failure in the glue line rather than adhesive failure in the oxide layer or at the glue/oxide interface.

Title: Appareil a plusieurs instruments pour les cabinets dentaires
IPC: A61C1/02
Filed: 1977-08-11
Abstract: Appareil pour cabinets dentaires à plusieurs instruments interconnectés de sorte que jamais deux ou plusieurs ne fonctionnent simultanément. L'appareil comporte pour chaque instrument un émetteur signalant la reprise de l'instrument de son support et un circuit d'activation logique connecté à l'émetteur et aux circuits d'activation des autres instruments. Il émet un signal d'activation pour son propre instrument et un signal de blocage pour les autres, quand il reçoit un signal de reprise de son emetteur sans qu'un signal de blocage soit reçu des autres circuits d'activation. Une seule ligne d'interconnexion 8 est prévue pour transmettre les signaux de blocage. Un circuit de reconnaissance 6, intercalé entre l'entrée concernée du circuit d'activation et la ligne d'interconnexion 8, est reliée à la sortie du circuit d'activation 4, de sorte qu'il retransmet un signal de blocage de la ligne d'interconnexion à l'entrée du circuit d'activation 4 seulement quand aucun signal d'activation n'apparaît à la sortie de ce dernier. L'emploi d'une seule ligne d'interconnexion réduit sensiblement le coût et l'encombrement de l'appareiL
