The substrate to be coated is cleaned then positioned in a rigid mold of ceramic or metal material having a defined mold cavity. The space between the mold cavity surface and the substrate is filled with a metal powder and the mold powder and substrate assembly is pre-sintered. The pre-sinter conditions are selected such that the powder lightly sinters together and adheres to the substrate but not to the mold cavity surface. After removal of the mold the coated substrate is further sintered to obtain the proper desired bond strength and pore volume. Sintering is carried out in n protective atmosphere.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention is a regulator circuit for combined regul-ation of the emitted wavelength from a laser diode, and its output. According to the invention, a fraction of the radiation from the laser diode (1) is caused to be transmitted, via a glass fibre (2) to a sensor unit (8). The sensor unit contains a dispersing device (3), possibly separate focussing devices, and a detector unit (4). The detector unit (4) contains one or more detector elements, whose electrical output signals are conducted to a signal decoding unit (5). The signal decoding unit (5) is connected (i) to a temperature generator (6), in turn conn-ected by thermal means to the laser diode, (ii) to a power generator (7) which is electrically connected to the laser diode. By using a concave lattice as the dispersing device, the reflective radiation from the lattice (3) is focussed on to the detector elements in the detector unit. By placing two detector units close together, side by side, and having the radiation focussed on the detector units adjusted such that the radiation beam, at the correct wavelength, hits the detector elements in equal measure, balanced electrical signals from the detector elements are obtained, any differential controlling the temperature generator (6), and the sum of which controls the power generator (7).

Abstract: RAILWAY EMERGENCY BRAKE SYSTEM                 Abstract An emergency brake control valve and a system incorporating the same that enables the locomotive engineer to remotely initiate emergency braking at the rear or any intermediate car of the train. The system includes a master unit that is contructed so as to be mounted in the locomotive of the train and a remote control unit that is contructed so as to be mounted on one of the cars. Preferably, the remote control unit is mounted on the last car so that emergency braking may be initiated at the rear of the train. Actuation by the engineer of an emergency brake switch (20) produces an output signal that is transmitted by a radio transmitter (22) and received by a radio receiver (24) in the remote control unit. In response to the received signal, an actuator (26) is energized to operate a solenoid valve (28) from a normally closed position to an open position to connect a control port (48) of an emergency brake control valve (30) to atmosphere. This produces a pressure differential that causes a movable valve member (70) in the emergency brake control valve to shift to an open position in which the vehicle brake pipe (21) is exhausted to atmosphere through an exhaust port (27, 44). To terminate emergency braking, the solenoid valve is closed. This, in turn, shifts the movable valve member to its closed position so that normal braking activities can be resumed. The invention is adapted for complementary use with a system that monitors and remotely displays a plurality of train status conditions. To enable supply of the brake pipe air pressure to pressure sensors (56, 58) in a train status-monitoring system, the movable valve member (70) has a passageway (81) that provides fluid communication between its primary and secondary sides. When the valve member is in its closed position, the brake pipe air pressure is supplied through this passageway and thence through the control port (48) to the pressure sensors for the brake pressure monitor. For use in either a stand-alone system or in conjunction with a remote monitoring system, the emergency brake control valve (30) has a glad-hand connector (34) so that the valve may be coupled directly to the existing glad-hand connection (36) for the brake pipe of the railway vehicle.

Abstract: METHODS OF AN APPARATUS FOR FLUID SUPPORT                  Abstract of the Disclosure A fluid support device is described that counter-acts the gravitational bending moment present in a sub-strate tube during a modified chemical vapor deposition preform fabrication process.  Hence, use of this device results in the production of a straight optical fiber preform.  The device includes a hemicylindrical annulus section in close proximity to the portion of the substrate tube to be supported, and uses flowing fluid to offset gravity and to center the substrate tube.  Gaseous use of the device increases and stabilizes the thermophoretic force without contact by either solid or liquid materials, avoiding any reduction in strength of the finished fiber.

Abstract: METHOD AND APPARATUS FOR SECURING UNIFORMITY AND SOLIDITY IN LIQUID JET ELECTROSTATIC APPLICATORS USING  RANDOM DROPLET FORMATION PROCESSES        ABSTRACT OF THE DISCLOSURE          Uniform application of a controlled relatively small liquid volume per unit area to a moving fabric substrate is obtained even though application is made using a liquid jet electrostatic applicator which employs random drop formation processes.  Repetitive print times during which randomly formed droplets are passed onto the substrate along a linear orifice array are controlled so as to have a minimum duration sufficiently large as to average out expected random variation in droplet formation processes occurring along the orifice array.  At the same time, the center-to-center spacing of each printed pixel (during which randomly formed droplets are intercepted so as not to fall onto the substrate) is controlled so as to maintain a desired relatively small controlled liquid volume per unit area within the fabric substrate section to be printed.  In one exemplary embodiment, the print times are maintained in excess of approximately 200 microseconds and/or so as to insure that the expected standard deviation of liquid volume printed onto the substrate during each print time is less than approximately 0.2.
