Abstract: Generator System with Fault Condition Excitation Abstract A generator system which is self-excited even during a fault condition includes a main generator having armature  windings  and  a  main  field winding which  is excited by a rotary transformer.  The rotary transformer includes  a  stationary primary winding  and a rotating secondary winding, with the primary winding receiving a controlled portion of the main generator armature output. The current through the primary winding of the transform-er is controlled by silicon controlled rectifiers which are gated by a voltage regulator circuit.  The voltage regulator  circuit  in  turn  receives  signals  from  the voltage delivered to the load, the highest phase current delivered to the load and the voltage at the main genera-tor armature output.  The voltage regulator controls the current through the primary winding of the transformer in accordance with the voltage delivered to the load if that voltage is greater than a predetermined value.  If the voltage delivered to the load is less than the prede-termined value, such as when a fault condition arises, the current through the primary winding of the trans-former is controlled in accordance with the voltage at the main generator armature output.  A current limiter is also provided to limit the output current from the main generator armature during a fault condition to maintain the  voltage  of  the  generator  armature  at  acceptable levels for self-excitation.

Abstract: ABSTRACT OF THE DISCLOSURE     A spring-system, used for the suspension of motor-vehicles, comprises  a mechanical, pneumatic, or hydro-pneumatic suspension-spring inserted between the sprung and the unsprung masses of the motor-vehicle.          The suspension-spring is linear and possesses relatively high positive rigidity with only short spring-travel.  Arranged in parallel with the suspension-spring is a correcting spring having negative rigidity and zero-crossover in the region of negative rigidity.  The cor-recting spring comprises two parts each equipped with permanent magnets, one of these parts being connected to the sprung mass and the other to the unsprung mass.          Each of the parts of the correcting spring comprises a plurality of permanent magnets arranged one behind the other in the direction of movement, with pieces of soft iron arranged therebetween, like poles of adjacent permanent magnets adjoining the soft-iron intermediate pieces, and the magnetizing axes of the permanent magnets being arranged in parallel with the direction of movement.  The arrangement is such that the magnetic flux, deflected by the soft-iron intermediate pieces perpendicularly to the direction of movement, produces, in both parts, like poles facing each other and re-pelling each other in unstable equilibrium at the same height in relation to the direction of movement.

Abstract: ELECTROFORMED CHARGE PLATE FOR INK JET PRINTERS               Abstract of the Disclosure A  charge  plate  for  an  ink  jet  printer comprises a plurality of  electrodes and connecting circuit  paths  embedded  into  a  molded  dielectric substrate and anchored thereinto by means of retain-ing flanges which extend from the innermost embedded ends  of  the  electrodes  and  circuit  paths.  The charge plate is formed by means of photolithographic, plating and molding  techniques.  Nickel electrodes and  circuit  paths  are  plated  through  a  position defining pattern in a photoresistive covering onto a copper foil sheet to a height slightly exceeding the photoresistive   covering   to  form   the   retaining flanges.  The photoresistive covering is then removed and the composite foil sheet/plating is bent toward the  plating  such  that  the  electrodes  extend  at approximately a 90° angle relative to the remainder of  the sheet.   The bent composite  is  then placed into   mold  and  an epoxy substrate  is  formed  to engage  and  surround  the  electrodes  and  circuit paths.  After curing, the substrate with the embedded circuit paths  and electrodes  is  removed  from  the mold,  excessive  copper  foil  is  trimmed  from  the edges and it is placed in a copper etchant to remove the copper foil sheet thereby exposing the charge surface and the conducting circuit path surface of the molded charge plate substrate.

Abstract: ABSTRACT OF THE DISCLOSURE           First and second separately actuatable triggers are mounted to a housing which carries a hollow needle through which a fastener is dispensed.  The needle is mounted to the housing for movement between original and extended positions.  The article to be tagged is situated adjacent the front of the housing.  When the first trigger is depressed, a tag is moved from a stack on the housing into alignment with the needle as the needle is moved forward to pierce the tag and article.  Also, a fastener is fed into the needle. When the second trigger is depressed, the fastener is moved through the needle such that the T-bar end is situated behind the article and the needle retracts to its original position.   The apparatus is pulled away from the article, leaving the tag affixed by the fastener.  The apparatus is light-weight, easily manipulatable, and can be operated by a single hand.

Abstract: ABSTRACT     A carbonation method and apparatus is described in which carbonation is achieved by forcing carbon dioxide in gaseous form from an atmosphere thereof downwardly into a body of water to be carbonated.   This may be achieved by a vaned rotor rotatable about a horizontal axis or other means.  The carbon dioxide atmosphere is preferably maintained at a pressure of about 100 psig (6.8 bars).  The degree of carbonation may be varied by varying the time for which the carbonation operation is carried  on. A  flavour  concentrate  supply  means, containing various flavours,  is pressurized for the supply  of  the  concentrate  utilizing  what  would otherwise  by  waste  carbon  dioxide  gas  from  the carbonation   chamber   after   completion   of   the carbonation operation.

Abstract: ABSTRACT          Double salt, process for its preparation and pharmaceutical composition containing it.      The double sulfate of 1-desoxy-(5-hydroxytryptamino)-D-fructose (DFS) and 1-methylhydantoin-2-imide (creatinine) represents a new solid crystalline phase of unit composition, pharmaceutical quality and remarkable stability.     It is prepared by glycosylation of serotonin with D-glucose, formation of the double salt by addition of sulfuric acid and creatinine and crystallization of the double salt in the presence of ethanol.  The DFS is preferably isolated from the reaction medium by way of the addition complex DFS.Ca(OH)2 which is precipitated by the addition of calcium hydroxide.   The calcium hydroxide is then eliminated by addition of sulfuric acid and the double salt crystallized as described above.     The DFS is the active principle of a medicament effective in particular in the treatment of leprosy.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention is a pressure sensing and measurement device that eliminates errors due to compliance and lack of sensitivity.  The cell uses a pressure receiv-ing means (such as a flexible diaphragm) to detect an impinging object, a means to counteract the pressure caused by the impinging object (such as internal hydraulic pressure), and a detector to measure the amount of internal pressure used to counteract the impinging force.  Since the cell is internally pressurized to a point equal to a value equal to the external pressure, the diaphragm is undeflected and may avoid the problems inherent in simple diaphragm systems (such as bridging and insensitivity).

Abstract: "EMERGENCY OXYGEN SYSTEM FOR AIRCRAFT" ABSTRACT OF THE DISCLOSURE           Emergency oxygen system of the type where masks are in com-partments in the backs of aircraft seats uses an underseat compartment located under the plane of the seat cushion to house the large canister of chemicals which generate the oxygen when the canister is activated. A spring loaded cable connects the two compartments so that when any of the tether cords connected to each mask is pulled, a locking pin is pulled free from a release mechanism for the cable.  Once released, the cable spring immediately moves the cable axially so its lower end can actuate another release mechanism in the canister compartment to activate the canister and produce oxygen.  Since the canister can reach a temperature of over 500°F, its removal from the seat back reduces any possibility of burns to passengers while allowing for a lower back height and less back thickness, thereby providing more passenger living space and less obstruc-tion to viewing of visual entertainment.
