Title: Continuously Operated Heat- treatment Furnace for Pipes
IPC: F27B9/24
Filed: 1981-07-30
Abstract: An apparatus for heat-treating pipes comprising a furnace chamber A for accommodating a plurality of pipes P as arranged in parallel, a chain conveyor 15 disposed in the furnace chamber for transporting the pipes P in a direction at right angles to the axes of the pipes, and a plurality of stopper means 20 for stopping the pipes intermittently at suitably spaced- apart positions in the path of transport by the chain conveyor 15 and causing each of the pipes to rotate about its own axis in cooperation with the chain conveyor 15. Since the pipe is intermittently stopped and rotated about its own axis during heat treatment, the pipe is free of thermal deformation to an elliptical shape. Pipes can be heat-treated in succession in a small space, therefor with a very high efficiency. The force of transport of the chain conveyor 15 is utilized for rotating the pipe without necessitating any additional device for the rotation, hence advantageous in cost. <IMAGE>

Title: Sliding walls of vehicles or containers, in particular railway freight wagons
Inventor: GIESE KLAUS-DIETER
IPC: B61D19/00
Filed: 1982-07-06
Abstract: Guide rails 4, 5 for sliding wall sections 1, 1 are arranged in mirror- symmetrical positions on a shaft 3 which is rotatable to cause the rail 4 to engage rollers 2 of the wall section and move the latter into a sliding displacement plane with the rail 4 then taking up the position originally occupied by the rail 5. The rail 4 is thus aligned with longitudinally adjacent rails 5 to enable the sliding wall section to move in front of wall sections still in their closed positions. Cams 6 mounted on the shaft 3 engage the associated wall section when the latter is being moved into its closed position and serve to lift and retain the closed wall section with its rollers clear of the rail 4. A claw secured to the wall section may be arranged automatically to engage an aperture in the rail 4 so as to prevent longitudinal movement of the wall section in its closed position. A torsion spring may act on the rotatable shaft 3 to reduce the effort required to overcome the weight of the wall section. <IMAGE>

Title: Making gaskets
Inventor: BATE CECIL ALBERT
IPC: B30B5/06
Filed: 1983-09-16
Abstract: A gasket of the kind comprising particles of compressed expanded graphite bonded to an apertured reinforcement plate is made by pressing the graphite particles onto the face of the plate without lateral support of those particles at the periphery of the plate, as by pressing between two compressor belts. In thus dispensing with vertical moulding elements, the method enables a more uniform density of graphite to be obtained over the surface of the plate, and yet leaves the graphite coating at the periphery acceptably uniform with the remainder. 
<??>The method is specially applicable to the manufacture of gaskets for the cylinder head of an internal combustion engine.

Title: Resistive circuit detector
Inventor: BRADFORD MICHAEL P
IPC: H02H9/02
Filed: 1984-04-02
Abstract: A voltage drop develops across a current-limiting resistor 14 connected between a power source 10 and a load 16 in proportion to the current draw. A zener diode 18 becomes conductive in the reverse direction when the voltage drop increases to a threshold, thereby turning on a light emitting diode 22 (LED), to detect excessive current draw. A photo-SCR may be optically coupled to the LED to provide a latched fault indication. For detecting partial or complete open loads, normal load current will be high enough for LED 22 to be on, and to turn off as current falls. A thermistor may be substituted for the current limiting resistor in certain cases to provide protection and detection at higher current demand levels. <IMAGE>
