IPC: C23F3/00
Filed: 1988-07-26
Granted: 1990-05-23
Abstract: The invention provides a physicochemical process for refining relatively rough metal surfaces to a condition of high smoothness and brightness, in relatively brief periods of time, which is characterized by the use of a non-abrasive, high-density burnishing media. The process can be carried out in one step and with minimal production of media fines, thus affording economic and environmental advantages.

Title: Method for obtaining a skin equivalent and so obtained skin equivalent
IPC: C12N5/00
Filed: 1988-03-02
Granted: 1991-01-16
Abstract: The method for obtaining a skin equivalent (27) involves preparing a dermis equivalent (24) by mixing contractile cells, a nutrient medium and collagen so as to form a gel which contracts; using this dermis equivalent (24) as a substrate for an epidermis equivalent (26) obtained by sowing with the keratinocytes from an animal or human explant. According to the invention, the substrate (24) is sown with at least one section of a hair follicle (22) comprising at least partially its cellular sheath, the said section being implanted substantially perpendicular to the free surface of the substrate. <IMAGE>

Abstract: A sintered-foil electrode for nickel-cadmium batteries is made of nickel-plated sheet steel in the form of a perforated strip-type support material for nickel powder deposited on it and sintered to form a porous layer, electrochemically active mass being incorporated in the pores of this sintered body in the form of nickel hydroxide or cadmium hydroxide. In order to increase the effective surface and the adhesion of the coating to the support material and the resultant electrical performance and mechanical durability of the associated battery, the invention proposes that the support material is a cold- rolled low-carbon steel strip which supports a nickel layer having a thickness of 2  mu m to 6  mu m and an electrolytically or electrolessly deposited cobalt or cadmium layer having a thickness of 0.1  mu m to 3  mu m.

Title: Process and device for the production of cheese
IPC: A23C19/06
Filed: 1989-07-05
Granted: 1993-06-23
Abstract: A process for the production of cheese, in which cut-up gel from a tank used for the concentration of milk is transferred into a flotation press with the aid of a conveying device, and after extraction of the whey from the gel the remaining curd, packed into moulds, is repeatedly and individually subjected to the compressive force of the respectively assigned piston of a pressing head belonging to the flotation press, but the moulds are to be turned between every two pressing operations. In order to reduce the heavy physical work in the production of small and moderate quantities, and to shorten the production time whilst at the same time improving the quality of the cheese, the process according to the invention is carried out in a manner such that the transfer of the gel takes place directly in sets of individual moulds provided within the flotation press and, after closure of all the individual moulds with a water-permeable cover in each case, the sets of moulds are subjected to alternating pressing and turning operations, at least the necessary raising and lowering of the sets of moulds during each turning operation being carried out mechanically. A flotation press for the production of cheese, to which is assigned a conveying device for the supplying of the gel, is characterised in that a plurality of sets of moulds (8), comprising in each case a rigidly cohesive row of individual moulds (9) extending in the width-wise direction of the flotation press (1), a distribution device (20), which is displaceable in the longitudinal direction of the flotation press (1) and serves to fill the said individual moulds set by set with the gel, as part of the conveying device, and a mobile turning mechanism (30) for the sets of moulds (8) which can likewise be moved along the flotation press (1) are provided. <IMAGE>

Abstract: A process is described in which hydrogen peroxide is added to the liquid and in which the liquid is then passed through at least one reactor, in which reactor the liquid is subjected to a short-wave electromagnetic radiation. To ensure a sufficient excess of hydrogen peroxide, a first part stream is removed from the treated liquid after leaving the reactor, which is merged with a second part stream containing a solution of reagent which can be reduced by the hydrogen peroxide. The end point potential of the mixture obtained by reaction of the hydrogen peroxide with the substance contained in the reagent solution is used to control the amount of hydrogen peroxide to be added to the untreated liquid.

Abstract: Whether or not a hit is given to a game is determined before symbol trains stop moving, or preferably when a start lever is manipulated for starting the motion of the symbol trains. For a game allowed to have a hit, the motion speed of symbol trains is switched from a high speed to a low speed, or the speed is set at a low speed from the beginning. For a game not allowed to have a hit, the symbol trains move at a high speed from the beginning. From the difference between motion speeds, a player can be given beforehand suggestion as to whether the game has been allowed to have a hit.

Abstract: Un stimulateur cardiaque intracorporel programmable (10) qui fonctionne sur la base du rythme auriculaire comprend des moyens qui empêchent que le c÷ur (12) ne soit stimulé à une vitesse limite supérieure pendant des périodes prolongées. Le stimulateur stimule le c÷ur à un rythme qui suit le rythme auriculaire jusqu'à la vitesse limite supérieure du stimulateur, puis continue à stimuler le c÷ur à cette vitesse limite supérieure, tout en continuant à surveiller le rythme auriculaire. Si le rythme auriculaire surveillé dépasse une deuxième vitesse limite supérieure, on considère qu'une arythmie auriculaire rapide ou tachycardie est présente, et le stimulateur passe automatiquement de son mode momentané de fonctionnement à un autre mode de fonctionnement, afin d'essayer d'arrêter ou d'interrompre l'accélération auriculaire. Des conducteurs (14 et 16) transmettent à des électrodes (15 et 17) des impulsions de stimulation générées par un générateur (18) d'impulsions auriculaires et par un générateur (20) d'impulsions ventriculaires. Un système de commande (26) génère des signaux de déclenchement qui sont transmis au générateur (18) d'impulsions auriculaires et au générateur (20) d'impulsions ventriculaires par deux lignes (32 et 34) de transmission de signaux. Des amplificateurs (22 et 24) sont invalidés par un signal d'effacement transmis à ces amplificateurs par le système de commande via des lignes (36 et 38) de transmission de signaux. Un circuit de mémorisation (40) est couplé au système de commande (26) par un bus d'adresses/données (42). Un circuit de télémétrie (44) est connecté au système de commande (26) par un bus d'instructions/données (46).
