Abstract: ABSTRACT OF THE DISCLOSURE A multi-stage condition control system of the time proportional type is shown.  The control system utilizes a counting means as part of the anticipation for system control.          The counting means counts during the time the control system is within its proportional band.  When the control system moves outside of the proportional band, the counting stops.          A count detection circuit senses the absence of counts thereby indicating that the system is outside of the pro-portional band.  The absence of counts is then used to increase or decrease multiple stages of condition control equipment to bring the system back within the proportional band.

Abstract: ABSTRACT:          The invention seeks to provide a humane trap which de-spatches trapped animals without pain or panic.  The trap com-prises a frame with a trap mechanism mounted in the frame and movable between set and sprung conditions.  The mechanism defines in its set condition a collar presenting a desirable opening to a species of animal to be trapped and gauged to resist the passage of the shoulders of an animal of that species.  The mechanism further comprises trigger means operatively associated with the collar to spring the trap mechanism in response to engagement of an animal's shoulders with the collar, and strike means operative on springing of the trap to strike across the plane of the collar opening with a force lethal to the species of animal to be trapped.  Preferably the collar is mounted for swinging movement relative to the frame, and such swinging movement caused by an animal pushing its shoulders against the collar is used to trigger the trap.

Abstract: Technique particulière de prospection géophysique, dite "à courants transitoires". Un dipôle récepteur capte répétitivement la réponse du sous-sol à une excitation impulsionnelle au niveau du dipôle émetteur. Les passages ainsi captés répétitivement sont composés statistiquement en une représentation brute de la réponse transitoire, qu'un prétraitement transforme en représentation lisée et normalisée. Pour chaque station, on prend avantageusement la dérivée logarithmique de cette réponse, (indicatrice locale IL). A partir de celle-ci, on détermine une indicatrice régionale IR, puis par différence (IL-IR) des indicatrices résiduelles. Convenablement représentées, celles-ci font apparaître certains traits de la structure du sous-sol.

Abstract: 48, 191 ABSTRACT OF THE DISCLOSURE This concerns an undervoltage relay device for a circuit breaker system with a time delay feature.   Two lines of the electrical system to be protected are moni-tored by a transformer.  The output of which is rectified and provided to a capacitive element which, among other things,  filters the signal.   The capacitive element may comprise a single capacitor or combination of capacitors. The combination chosen is the function of the amount of time delay desired.   If the voltage across the monitor lines drops below a predetermined value, the voltage level across the capacitive element begins to drop accordingly. This decreasing voltage signal  is provided by way of a voltage divider to one input terminal of a comparator. The  other  input  terminal  of which  is maintained  at  a reference voltage.   When the signal voltage drops below the  reference voltage,  the comparator shift state thus causing an undervoltage relay coil to be deenergized.  The armature of the undervoltage relay coil is spring biased so that upon deenergization the armature moves under the influence of the bias thus tripping the circuit breaker. The capacitive element additionally supplies the voltage for the relay coil.  The discharge path for the capacitive element is deliberately chosen so that sufficient voltage will be supplied to the relay coil to keep it energized during the time out period of the time delay element, even though the voltage across the lines has dropped to a lower value.  The time out is a function of the capacitance of the capacitive element and the resistance of the discharge 48,191 path.  The output of the previously described comparator element is  feedback to another comparator element which controls one of the resistive elements of the previously described voltage divider.  When the output of the first comparator element changes states, the second comparator element acts in such a way as to change the effect of the resistive element in the voltage divider path thus latch-ing the  first comparator into its last obtained state. Another feature is a light emitting diode which is con-nected  in  series with  the  undervoltage  relay coil and which  extinguishes when  the undervoltage relay coil is deenergized, thus providing a positive indication that an undervoltage relay condition exists.   Still another fea-ture includes a memory means which extinguishes when the undervoltage relay condition exists and which remains in a disposition of non-illumination.  Even if the undervoltage relay condition disappears to provide an indication to an operator that an undervoltage relay condition had occurred previously.

Abstract: ABSTRACT   OF   THE   DISCLOSURE        A process for economically converting carbo-metallic oils to lighter products includes providing a converter feed containing 650°F+ material characterized by a carbon residue on pyrolysis of at least about 1 and by containing at least about 4 parts per million of Nickel Equivalents of heavy metal(s).        The converter feed is brought together with cracking catalyst to form a stream comprising a suspension of said catalyst in the feed and the resultant stream is caused to flow through a progressive flow type reactor having an elongated reaction chamber which is at least in part vertical or inclined for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds at a temperature of about 900 to about 1400°F and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and with coke being laid down on the catalyst in amounts in the range of about 0.3 to about 3% by weight.        The catalyst is separated from the stream of hydrocarbons formed by vaporized feed and resultant cracking products, and adsorbed hydrocarbons are stripped from the separated catalyst.        The catalyst is regenerated with oxygen-containing com-bustion-supporting gas under conditions of time, temperature and atmosphere sufficient to reduce the carbon on the catalyst to about 0.25% by weight or less, while forming gaseous combustion product gases comprising CO and/or CO2 and the regenerated catalyst is recycled to the reactor for contact with fresh feed.
