Granted: 1991-10-01
Abstract: METHOD AND APPARATUS FOR PLASMA SOURCE ION IMPLANTATION          ABSTRACT OF THE DISCLOSURE     Ion implantation into surfaces of three-dimensional targets is achieved by forming an ionized plasma about the target within an enclosing chamber and applying a pulse of high voltage between the target and the conductive walls of the chamber.  Ions from the plasma are driven into the target object surfaces from all sides simultaneously without the need for manipulation of the target object. Repetitive pulses of high voltage, typically 20 kilovolts or higher, causes the ions to be driven deeply into the target.  The plasma may be formed of a neutral gas introduced into the evacuated chamber and ionized therein with ionizing radiation so that a constant source of plasma is provided which surrounds the target object during the implantation process.  Significant increases in the surface hardness and wear characteristics of various materials are obtained with ion implantation in this manner.

Abstract: !                                            B 61816518 ABSTRACT OF THE DISCLOSURE  .      A heating apparatus  is  disclosed  for  heating a calender  roll.   The heating apparatus  utilizes heat supplied by induction heating and from a heat transfer medium .  The heating apparatus includes heating channels defined by the roll.  The channels extend through the roll such that the heat transfer medium is permitted to flow through the channels so that heat is transferred from the transfer medium to the roll.   An induction heater is disposed adjacent to the external surface of the roll and extends  along substantially the entire length of the roll such that when the induction heater is energized, heat is induced in the region of the external surface of the roll for supplementing the amount of heat transferred from the heating medium so that the temperature of the external surface of the roll is increased to a level which, in the absence of the induction heater, would cause excessive shell stress.   Furthermore,  the temperature level  is attainable without the hazards associated with the use of a heat transfer medium operating at  least  at such temperature level.

Abstract: COOLING SYSTEM FOR GASIFIER BURNER OPERATING IN A HIGH PRESSURE ENVIRONMENT                          (D#78,323-F) ABSTRACT         A burner for operating in a high temperature and high pressure  atmosphere  such  as  in  a  fuel  burning  gasifier, requires a high degree of cooling such as by water circulation through the burner.   In  the  event of physical breakage or damage to  the normal cooling system, means is provided for introducing a higher pressure coolant into the system.   The latter fills the system, both upstream and downstream of the cooling  coil,  to  permit  progressive  discontinuance  of the burner operation without substantial damage.  It further avoids the backflow of gas from the high pressure gasifier which would otherwise be discharged to flow back through the cooling system and  be  discharged  into  the  atmosphere  thereby  creating  a dangerous as well as a harmful environment.

Abstract: MAGNETIC BRIDGE DEVICES                    ABSTRACT OF THE DISCLOSURE Various devices are constructed with gap-modified magnetic bridge circuits.  In a magnetic bridge device for evaluation of samples, a magnetic bridge circuit (10, 20, 30, 40, 40; 50) as at least four arms (P1-P2; A12-B12, A13-B13, A14-B14, A15-B15), a driving leg (A11) and a sensing leg (B11), one of the arms (A15-B15) being utilized for evaluating a sample (S), pole pieces (P1-P2) of a sample-evaluating arm having end faces defining between them a sample-evaluating gap (G15).  An electrically conductive gap insert (C) produces an enhanced fringing flux exteriorly of it.  The sample (S) is placed in juxtaposition to the sample-evaluating gap for affecting the fringing flux.  A-driving circuit (WA1) for the driving leg provides a time-varying flux path within the four arms of the bridge.  A sensing device (WB1) associated with the sensing leg senses changes in the sensing leg caused by changes in the fringing flux resulting from characteristics or movement of the sample.  A specific single-side modification provides an accelerometer (40`).  Other device embodiments may be used for evaluating a tubular structure (T), such as pipe, for detecting flaws within the pipe or other structure.  In one form, the device (50) of the present invention is inserted wholly within the tubular structure, and includes driving and sensing legs (54,56) having axes which each intersect symmetrical axis of elongation of the structure and which are, themselves, mutually perpendicular, being preferably spaced apart along the direction of elongation to introduce time-varying flux within the walls of the structure four effective arms of the magnetic bridge, divided into quadrants of the structure.  A structural anomaly in any quadrant causes an imbalance sensed by a coil wound about the  sensing leg.  The quadrantal magnetic flux components may extend both circumferentially and axially within the walls of the structure.

Title: Method for the manufacture of alloy railway rails
Inventor: ACKERT ROBERT J
IPC: C21D1/00
Filed: 1989-08-14
Granted: 1992-10-20
Abstract: ABSTRACT     An improved method for the manufacture of hardened railroad rails comprises the steps of forming a railroad rail from an alloy steel of a preselected chemical composition, force cooling the rail from a preselected cooling start temperature above about the austenite-to-ferrite transformation temperature, terminating the force cooling when the temperature of rail reaches a preselected cooling stop temperature, and before a substantial volume fraction of the austenite in the rail head has transformed to pearlite, and holding the rail under substantially isothermal conditions until the austenite-to-pearlite transformation is complete.  The chemical composition of the alloy steel is selected such that the austenite-to-pearlite reaction occurs earlier in time than the austenite-to-bainite reaction under the substantially isothermal conditions.  The use of this method makes avoidance of bainite easier to achieve, so relatively simple and inexpensive process control equipment can be utilized.

Abstract: An FCC catalyst regeneration technique in which the catalyst is regenerated in a dense bed regenerator.  Regeneration effluent gases are collected from different parts of the regenerator vessel in a common collection zone and passed through the catalyst separation cyclones from the common collection zone.  The cyclones may be arranged with their inlet horns adjacent one another in the common collection zone or a cyclone inlet manifold with a common inlet may be connected to the cyclone inlets.  The inlet port to the manifold may be extended to form an elongated vertical duct through which regeneration effluent gases and entrained catalyst pass from the dilute phase of the dense bed to the cyclone so that mixing of the effluent gases is promoted to ensure combustion in residual quantities of oxygen present in the effluent gases before the gases enter the cyclones.  Improved operating flexibility is obtained together with a reduced likelihood of cyclone damage as a result of localized high temperature excursions.  In addition, the NOx level of the regenerator stack gases is reduced by introducing unregenerated spent catalyst at different heights of the regenerator and contacting such catalyst with regeneration effluent gases.

Abstract: A conditional replenishment video data transmission system involves the transmission of updating digital data for clusters of consecutive picture elements, all or most of which show a change since the previous frame, in lines of a raster over an image to be transmitted. The lines of the raster are numbered cyclically in groups of 8, the numbers being part of line synchronizing code words, and the position along a line of the first element of each cluster is identified by a number. The data are transmitted at a constant rate from a transmitter buffer to a receiver buffer and an auxiliary data store records the addresses of the line synchronizing code words in the receiver buffer. The address of the receiver buffer read by a reading means can be corrected by reference to the address data in the auxiliary storage means if for example the line numbers do not follow in sequence or the element addresses are not in ascending order due to corruption during transmission. Alternatively, the reading means may be controlled at all times by the address data in the auxiliary storage means and not only when a tracking error has occurred. The tracking of the received data in the receiver buffer by the reading means may show a consistent error relative to the position predicted by the assumed transmission delay time; preferably such tracking errors are corrected by a whole frame jump using a receiver buffer of more than one frame capacity.
