Abstract: ABSTRACT OF THE DISCLOSURE:           A granulated composition of self-extinguishing polycarbonate containing carboxylates of general formula (I) of metals of Group I A, I B, II A or II B of the Periodic Table of elements, or of ammonium:                                           (I) where A1 and A2, may be for example a polycondensed benzene; B1 and B2, may be for example halogen atoms; m and n may vary from one to five; s1 and s2 may vary from zero to five; z1 and z2 may vary from zero to six; and i may be zero or one.  When the carboxylic acid of general formula (I) is salified with a metal of Group I A, I B, II A or II B of the Periodic Table of elements, X is a di- or pluriradical e.g. -SO2-.  When the carboxylic organic of general formula (I) is salified with an amino group, x is a di- or pluriradical e.g. >N-R-N<; where R is aliphatic.   The composition may be used to confer flame resistance on a variety of objects.

Abstract: FRACTURING METHOD FOR STIMULATION OF WELLS    UTILIZING CARBON DIOXIDE BASED FLUIDS      Abstract of the Disclosure A method of fracturing a subterranean formation with a stabilized foamed fracturing fluid comprising from about 50 per-cent to in excess of about 96 percent by volume of carbon dioxide with the  remainder comprising an aqueous liquid and a selected surfactant.  The foam is formed in situ by injection of a stabi-lized liquid-liquid emulsion containing liquid carbon dioxide into a well bore penetrating the formation.  The temperature and pressure of the emulsion is controlled to maintain the carbon dioxide in the liquid phase during injection into the well bore. thereafter, the carbon dioxide is heated by the subterranean for-mation to a temperature above about 88° F. at which time the sta-bilized emulsion spontaneously forms a high quality stabilized foam.

Abstract: METHOD OF FORMING BATTERY ELECTRODES            ABSTRACT OF THE DISCLOSURE     A method for forming battery plates or electrodes produces a substantial reduction in the forming energy per gram of active material, by providing the plates or electrodes being formed with energy in the form of at least three, and preferably eight, constant-current steps, an intermediate step being a higher current level than steps which precede or follow it.  A low constant current is provided at the beginning of formation, when plate resistivity appears to be high due to the resistivity of the raw material, a higher constant-current is provided when formation has begun and plate conductivity is high, and a lower constant-current is provided towards the end of formation, as plate or electrode potential builds towards full charge.  The method and apparatus disclosed is used in the tank formation of positive and negative battery plates or electrodes for use in dry charged batteries having antimonial and calcium grid positive plates.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention is concerned with a method of opening, axially shirring and dividing off tubular casing material, especially synthetic casing for the sausage manufacture, to form tubular folds or corrugations, and of subsequently conveying the same to a processing location such as, especially, the charging tube of a sausage stuffing machine, with the shirring being performed by pushing forward the tubular casing material against stop means.  In accordance with the invention, the said stop means will be put into operation only after the beginning of the advancing movement at a point located in spaced relationship behind the starting end of the tube and is then moved back in accordance with the length increment of the corrugation in the shirring direction.  The divided-off tubular corrugations are fed to the processing location by reverting the movement of the stop means in the opposite direction, thereby maintaining an unshirred section permitting an easy closing of the front end of the corrugation for further processing on the stuffing machine.

Title: Power actuated operator for windows and the like

Granted: 1987-02-24
Abstract: Abstract of the Disclosure A power actuator for a window includes a rotary drive member and a rotary driven member which is turned by the drive member and which is connected to the sash of a window to open and close the sash as the drive member is turned in one direction or the other. A reversible electric motor drives a speed reducing gear train and the output gear of the train is coaxial with and rotatable relative to the drive member, a crank arm with a projecting pin is pivotally mounted on the drive member to swing between an active or radially projecting position and an inactive position overlying the drive member. When the arm is in the inactive position, the pin connects the output gear and the drive member so that the motor may turn the driven member. With the arm in the active position, the pin no longer couples the output gear and the drive member and the latter may be turned manually by the crank arm independently of the gear train. When the sash reaches either the fully open or fully closed position by power actuation, the motor stalls and the stall current is sensed to stop the motor and reverse the latter momentarily to relieve the torque in the gear train.

Abstract: Voltage Regulator Abstract A motor driven generator has a generator con-trol unit which incorporates a programmed microproces-sor to control generator operation.  A generator volt-age regulator utilizes the microprocessor of the gen-erator control unit to develop an error voltage which is added to the average phase voltage of the generator, controlling the generator field current.  In the event of a phase failure the generator control unit senses an abnormally high phase voltage condition, disables the average phase voltage circuit.  In the event of an abnormal difference between the high and low phase voltages, the gain of the error signal circuit is re-duced.

Abstract: ABSTRACT OF THE DISCLOSURE A system and method for generating a unique sync pattern that may be appended to a selected data sector of a disk storage system (20).  The data to be stored in the disk storage system is encoded in accordance with a desired  fixed rate run-length limited code, such as a 2-7 code.  The unique sync pattern is generated by first encoding  a  prescribed  data  word  (BF7A)  in  accordance  with  the desired code.  At least one bit of the encoded prescribed data word is then changed in a manner such that the changed encoded word still complies  with  the  coding  rules  of  the  desired  code,  yet  the resulting bit pattern does not represent any valid sequence of data in accordance with the desired code.   Hence,  the changed encoded word may be readily distinguished from data using sync detect logic (204),  thereby providing the synchronization function,  while still being handled and processed by the same encoding/decoding circuitry (136, 137) as is employed to handle and process the data.

Abstract: ABSTRACT     The invention is concerned with a process for rejuvenating an aqueous acidic trivalent chromium electrolyte which has been impaired in effectiveness due to the contamination by excessive quantities of hexavalent chromium, the electrolyte containing triva-lent chromium ions, a complexing agent for maintaining the trivalent chromium ions in solution, halide ions, ammonium ions and hydrogen ions to provide a pH on the acid side.  The process of the invention comprises the step of adding to the electrolyte a reducing agent comprising vanadium ions in at least an amount sufficient to reduce the concentration of hexavalent chromium ions to a level which is not in excess of 0.4 grams/liter.          The invention enables one to restore the plating efficiency and throwing power of a chromium electro-plating bath while avoiding the costly and time consum-ing step of dumping and replacing the electrolyte.

Abstract: ABSTRACT:           The invention relates to a slave-type interface circuit.  It can receive signals from a bus if the coding A0, A1 and A2 of its inputs S0, S1 and S2 corresponds to that mode of operation.  The signals from the bus are then delivered to the inputs L1 and L2.  With another mode of operation the coding of inputs S0, S1 and S2 corresponds to off-line operation on the basis of logic levels applied to the same inputs L1 and L2.  A branching block (SBL) directs the signals from the inputs L1 and L2 either to a bus receiver RBUS or directly to a decoder CDEC controlling a group of switches (COM).  In the case of operation with a bus, the bus receiver (RBUS) controls the logic for the progress for operations.
