Title: Formulations and process for effecting stoppage  of leaks of liquid from tanks, pipes and the like
Inventor: LYTTON DONALD B
IPC: F16J15/20
Filed: 1978-06-22
Granted: 1982-06-15
Abstract: Abstract of the Disclosure Formulations, and process, particularly for temporarily, but effectively, stopping leaks in tanks or pipes and the like through which liquids such as gasoline, oil, water or similar liquids are running or flowing, at low pressures, until a permanent repair of the leak or crevice through which said liquid is seeping can later be made.  The formulations are in the form of two separate compositions, each of which is of generally putty consistency, which are blended together just prior to use to form a product having a putty or putty-like con-sistency which is pressed into the area through which leakage of the liquids is occurring.  The formulations, when blended together or admixed for use, contain one or more epoxy resins, one or more epoxy curing agents, one or more waxes or waxy materials, and, advantageously, one or more fillers, with or without minor proportions of one or more supplemental ingredients.

Abstract: Perfectionnement et au dispositif au procédé permettant de réaliser l'épuration de gaz contenant des composés solubles dans un liquide.  Dans un dispositif du type colonne de lavage cyclonique.  On réalise dans une première zone ou zone de lavage la combinaison d'un courant gazeux cyclonique et d'une pulvérisation verticale de liquide de haut en bas, dans une deuxième zone de la colonne ou zone de dévésiculage la combinaison du courant gazeux cyclonique et des parois de la colonne de manière à arrêter les vésicules sous forme de pellicule liquide et on empêche l'entraînement de la pellicule liquide jusqu'à la sortie des gaz. Le perfectionnement selon l'invention consiste à réaliser avant la zone de lavage de la colonne cyclonique une zone de lavage préliminaire dans laquelle le gaz à traiter subit une accélération et une turbulence telles qu'il se charge de fines gouttelettes avant son introduction dans la colonne cyclonique.  L'invention permet d'améliorer l'absorption sans créer d'inconvénients dûs aux vésicules, et s'applique avantageusement aux absorptions accompagnées de réaction chimique et nécessitant moins d'un plateau théorique.

Abstract: ABSTRACT            An electric cooker comprises a fitting plate having an opening surrounded by an upwardly projecting rim, a cooker plate received in the opening and having a cooking surface on which a cooking vessel can stand, and a sheet metal ring surrounding the cooker plate and extending outwardly therefrom.  The ring has an internal section which is detachably mounted to the cooker plate and an external section which extends generally downwardly and beyond the rim to terminate adjacent the fitting plate.  The sheet metal ring is so shaped and arranged to provide a smooth transition from the cooking surface to the fitting plate.  The electric cooker of the invention allows relatively flat cooking vessels to be shifted more easily on the stove while preventing issuing liquids from penetrating through the stove surface.

Abstract: RANDOM ACCESS STORAGE DEVICE WITH A              MOVABLE RECORDING MEDIUM            Abstract of the Disclosure A random access storage device has signals recorded on tracks (assigned addresses in advance) on a rotary recording medium such as an optical video disk.  These addresses are randomly searched for at high speed.  Erroneous searches attributable to a transient phenomenon such as a jump for the search, a drop-out, etc. are prevented.  To this end the device has an error check circuit.  In a random access operation, a read head is mechanically moved to the vicinity of a target address, whereupon an address signal of a track to which the head has moved is read.  Whether or not the address signal is normal is decided by the error check circuit.  If the address signal is decided to be normal, it is stored in a register as a reference address.          A light spot is deflected by the number of tracks that correspond to the difference between the reference address of the register and the target address. If the address signal is decided to be abnormal, the light spot is unconditionally deflected onto the adjacent track.  An address signal is again read out at the new position.  Thereafter, the error decision and the other above described operation are again carried out.

Title: Arrangement for suppressing high frequency  currents in bearings of shafts
Inventor: GRASSMANN HANS-CHRISTIAN
IPC: F16C19/52
Filed: 1979-09-06
Granted: 1982-08-24
Abstract: ABSTRACT OF THE DISCLOSURE In order to suppress the high-frequency currents in bearings of shafts, the bearing capacity is arranged in the configuration of an electric quadrupole in such a manner that the high frequency voltage becomes a minimum. In the case of ungrounded shafts, a further impedance is provided between the bearing housing and the housing of the treatment chamber such that the sum of this further impedance and the impedance of the shaft are great compared to the bearing impedance.  Additionally, a low resistance in the form of a sliding contact is shunted across the bearing impedance.  The further impedance according to one embodiment is a capacitance and in another embodiment is a parallel L-C resonant circuit which is connected in series with the bearing. The capacitance of the L-C circuit is formed by an insulating plate and the inductance by a winding.

Abstract: ABSTRACT OF THE DISCLOSURE Processes are provided for producing specifically recited human Le form interferon proteins.  These processes comprise either subjecting a solution containing human Le form interferon proteins to affinity chroma-tography such that the human Le form interferon proteins are selectively retained, and eluting the retained interferon proteins; or cultivating a microorganism carrying DNA coding for the production of the Le form inter-feron proteins, and recovering the proteins from the culture medium. Such strictiy monospecific anti-interferon is extremely useful for antibody af-finity chromatography for purification of crude or partially purified inter-feron to obtain, in a simple and economic way, large amounts of pure Inter-feron or highly purified interferon for clinical purposes, standardization, chemical studies, sequence studies, and as immunogen for repeated preparation of monospecific anti-interferon.  The monospecific anti-interferon is also useful for establishing a genetic engineering system for the production of interferon protein.

Abstract: METHODS AND APPARATUS FOR SENSING WELLHEAD PRESSURE            Abstract This invention relates to methods and apparatus for monitoring fluid pressure in a subsea petroleum instal-lation or other similarly inaccessible system while isolating the well fluid from the production control system.  In one particular form of the invention, a body of secondary fluid is pressure-responsively coupled to but isolated from the oil or other primary fluid of interest by a piston, which subjects the secondary fluid to the pressure existing on the primary fluid.  In addition, a measuring device is connected to the secondary fluid to derive an electrical signal represen-tation of the pressure on the secondary fluid as a correlative indication of the wellhead or other pressure actually sought to be measured.  Further, the isolating device is constructed and arranged to effectively seal off the primary fluid from escape into the environment or into the production control apparatus and the pressure of the priamry fluid is maintained in the event of damage to any portion of the chamber enclosing and holding the secondary fluid.  It is a particular feature of this invention to provide at least a minimum pressure on the secondary fluid of a magnitude such as to effectively limit the further compression of the secondary fluid by the piston, when the piston is initially subjected to the primary pressure.

Abstract: ABSTRACT Petroleum crude and certain liquid distillate fractions derived there-from, and other sulfur containing fuels or residues are reduced in sulfur con-tent by intimately contacting the fuel or residues with alkanol solutions of al-kali metal hydrosulfides, at temperatures and pressures from ambient up to the critical temperature of the alkanol for from 1 to 20 minutes.  Thereafter, the fuel is caused to separate from the alkanol solution by the addition of water. A liquid-liquid separation separates desulfurized fuel from the alkanol solu-tion.  Hydrogen sulfide formed in the process is used to regenerate alkali met-al hydrosulfide for use in desulfurizing additional petroleum fuel.
