Abstract: CUTTING APPARATUS            ABSTRACT     A cutting appparatus for cutting a longitudinally extending member such as rail comprises a frame; means for clamping the frame to the member to be cut; and a cutting torch which is pivotally attached to the frame. A pivoted torch holder is provided having bearing means permitting axial displacement of the torch relative to the member to be cut.  The precise axial distance of the tip of the torch relative to the member to be cut is determined throughout the making of the cut by means comprising a plate attached to the frame and defining a cam surface and a cam follower connected to the torch.  The shape of the cam surface thus makes it possible for the path described by the tip of the torch to conform, if desired, to the profile of the member to be cut.     BACKGROUND OF THE INVENTION     This invention relates to cutting apparatus, particularly but not exclusively to cutting apparatus for transversely cutting through complexly shaped, longitudinally-extending members such as rails.            In order to repair or replace damaged rail welds it is frequently found necessary to cut the weld out of the rail. This is currently done using an oxygen-fuel gas torch. In order to help the cutting operative make the cut it is known to fix over the rail a template having three spaced apart torch holding pegs (or  sockets) to which complementary sockets (or pegs) attached to the torch may be fitted.  The torch may be pivoted about each associated peg to enable the cut to be made in three parts.  In practice, this arrangement

In the control circuit, a digital/decimal converter (N/D) con-verts the hour unit digital data into a one out of ten code signal.          The tenth outputs (E0 to E9) of the converter are connected to the vertical wires of a cross-point matrix having three pairs of output wires (00 to 05). The output pairs are respectively assigned on the hours of which the tenth figures are 2, 1 and 0. The output wires are connected to the corresponding inputs of a logical circuit (22) which has also other inputs connected to the active outputs of the clock when the hour tenth figure is 1 or 2, respectively. Cross-points (D3 to D17) of the matrix are selectively connected in accordance with the different predetermined programs. Electronic contacts (X7 to X10) are mounted on the output wires (01-02) of the matrix and controlled by the program selecting circuit  (SP).  The output of the logical circuit  (22)  is connected to a reference value adjusting potentio-meter  (P1),  the voltage transmitted to said potentiometer,  through the  output  (13)  of  the  logical  circuit  (22)  varying between two values  in accordance with the logical levels of the inputs of the logical circuit (22).     The thermostat comprises a bistable relay, means for energizing the coil (SW) of said relay in one direction or the other during the successive changes of state of the output of the temperature sensor of the thermostat, one contact (SW2) of said relay closing or opening the output circuit (F3, F4) of the thermostat, and means for de-ener-gizing the coil  (SW) between the changes of state of the output of said temperature sensor. The switching means of the coil comprise an assembly of electrical cells.     An inverter (X15, X16) is mounted between the back panel termi-nal (33) of the clock (21) and the corresponding input terminal (40) of the display device (DA). The other input terminal of the inverter is connected to the blinking output (9) of the clock digital circuit (Z1).  The  inverter  (X15,  X16)  is  controlled  by  a  circuit  which measures the voltage of the cells  (S1,  S2,  S3),  and switches the blinking  output  (9)  to  the back  panel  signal  input  (40)  of the display  device  (DA)  when said voltage  falls below a predetermined value .

Abstract: Case 2844 ROTOR PROTECTION APPARATUS ABSTRACT OF THE DISCLOSURE Apparatus for protecting a squirrel cage induction motor against excessive temperatures which can occur in the rotor, provides a thermal model of the rotor.  The thermal model has three regions A, B and C representing the starting portion of the rotor conductor, the main portion of the rotor conductor, and the rotor core.  The rotor is frequency sensitive and currents of higher frequency induced in the conductors tend to be in region A, and currents of lower frequency tend to be in region B.  Equipment connected to the stator winding determines values for the positive and negative sequence components of the supply for the fundamental frequency and preferably also for the second and third harmonics present, and provides signals representing these values.  Heat calculation circuitry receives the values for all the positive and negative sequence components and a signal representing speed, determines the currents that would be induced in regions A, B and C, and derives equivalent currents which would produce the same heat.  A summing circuit sums these equivalent currents for each of the regions A, B and C and applies the summed values to a first, second and third storage devices which stores the values representing temperatures.  Interconnections between the three storage devices simulates the thermal resistance between the regions A, B and C and the thermal resistance to ambient. A temperature detector is connected to each storage device and when the value stored in the storage device reaches a predetermined level representing a critical temperature, the detector provides a trip signal which interrupts the supply of power to the motor.

Abstract: ABSTRACT    The addition of a small amount of a halogen compound, e.g. chloroethyl phosphate, in a process producing elastomeric polyurethane RIM parts using tertiary amines as the chief catalyst component results in scavenging the residual amines after the part has been cured by annealing.  The parts from such a process can be coated with a wide variety of enamels having a high solids content and completely cured to result in a higher degree of adhesive between the coating and the part's surface than those parts from a process without the use of such a halogen.

Abstract: METHOD AND APPARATUS FOR SIGNAL RECOVERY    IN A LOGGING WHILE DRILLING SYSTEM Abstract of the Disclosure A method and an apparatus are provided for recovery of data in a well logging while drilling system wherein a data signal originating from a downhole apparatus is transmitted to the earth's surface through drilling mud. The method includes measuring pressure pulsations in a mud flow line at the earth's surface in two spaced apart locations then combining the data signals to cancel downhole propagating pressure waves such as surface generated interference noise.  The combined data signal is then processed by convolution filters, and then passed through a detector to determine the presence or absence of a valid data signal.  In the apparatus these data signals are passed through the drilling mud by pressure fluctuations originating at a downhole apparatus.  Two closely spaced pressure sensors measure mud pressure pulsations in a mud line at a surface location.  One of the measured pressure pulsation signals is time shifted an amount equal to the travel time of the group propagation acoustic velocity in the mud between the two pressure sensors.  One of the two signals has its polarity reversed and the two signals are combined to cancel any downward propagating energy from the combined pressure data signal.  The combined pressure data signal is then processed by each of n matched filters in a baseband PCM system to determine the presence or absence of one of n symbols in the residual data signal.  Each output of the filtered data signals is then input to a "Largest of" Bayesian detector to identify either the presence of a symbol or absence of the data signal.

Abstract: A powder feed control system employs an arrangement of conduits and valves for selectively directing a gas flow either through a powder feeder or through a bypass so as to quickly and precisely control the introduction of powder into and the removal of powder from the gas flow in a plasma spraying system. The arrangement of conduits and valves includes a two-way solenoid operated valve for directing the gas flow either into a powder feeder through a main conduit or into a bypass conduit which rejoins the main conduit on the other side of the powder feeder at a powder shutoff valve and a bypass and check valve. The bypass and check valve insures that the gas flow in the bypass conduit flows to the output rather than upstream to the powder shutoff valve. The powder shutoff valve includes a resilient member mounted within the bore of a housing and collapsible upon itself to close off an internal bore therein in response to the introduction of pressurized gas into a space between the housing bore and the resilient member. Air introduced into a cannister in the powder feeder with the loading of powder into the cannister is removed by an arrangement which includes a valve for selectively coupling the inside of the cannister to a vacuum source.
