Title: Temperature-controlled fluid coupling
Inventor: BRUNKEN GERD
IPC: F16D35/02
Filed: 1982-12-03
Abstract: The temperature-controlled fluid coupling for the fan of an internal combustion engine comprises two coupling parts (3, 7) rotatable in relation to one another about a common axis (5) of rotation, while a working chamber of a first coupling part (7) carrying fan blades (9) encloses the second coupling part (3), which is driven by the internal combustion engine. Between mutually adjacent faces of the working chamber (13) and of the second coupling part (3) several shear gaps (25, 27), filled with shear fluid in the operating condition, for the transmission of the drive torque extend between different radii. The width of the shear gaps (25) is dimensioned in dependence upon the radial distance from the axis of rotation, and increases with increasing distance. In this way a more uniform shear loading of the shear fluid can be achieved. The disengagement time of the fluid coupling is reduced. <IMAGE>

Title: Hydraulic buffer for elevators with air flow to remove contaminants
Inventor: BIALY LOUIS
IPC: F16F9/06
Filed: 1984-07-11
Abstract: A hydraulic elevator buffer includes a fluid container 16 containing a piston 12 which is pushed down within a cylinder 18 into a volume of hydraulic fluid. The buffer has no seals separating its interior from the atmosphere. As the piston 12 is pushed down, the displaced liquid is forced through ports 18a in the cylinder 18 which gives rise to a restricting force. The displaced liquid escapes into a chamber 19b in which an air/liquid mixture is produced. An annular passage 19d surrounds the piston at the top of the container, and the mixture is forced through the passage, separating the fluid and air. The fluid condenses down, lubricating the piston. The air is forced out through the space 16b between the sleeve 16c of the fluid container and the piston, removing any contaminants around the piston. The container is provided with a fluid filler hole 26 which is at an angle to the horizontal at which a minimum and maximum fluid level in the container can be determined by looking in the hole. The maximum is the level 26a at which the fluid flows out of the hole, and the minimum is the lowest level 26b at which the fluid can be seen in the hole. <IMAGE>

Patent GB-2156622-A (GB)
Title: Target location method and apparatus
Inventor: HEIN ROCHUS
IPC: G01S3/78
Filed: 1985-03-04
Abstract: In a method and apparatus for locating and determining the direction of a source of radiation, especially a target which radiates heat, radiation from the source is passed through a modulator 2 and detected by a photoelectric cell 1, the modulator being arranged such that the phase of the modulation of the output from the cell is representative of the physical deviation of the source from a reference axis. The signal from the cell 1 is amplified and passed to a digital frequency and phase analyser to generate digital values for feeding to a microprocessor 5 together with a reference frequency signal from the modulator 2. These signals are processed by the microprocessor and, as a result, the deviation of the source from the reference axis is established. This digital method has advantages over analogue systems in that it reduces the volume of electronic circuitry and residual ripple on the deviation voltages. <IMAGE>

Title: Method for joining polyolefin pipes by fusion
Inventor: STAFFORD TREVOR GEORGE
IPC: F15B11/02
Filed: 1986-01-06
Abstract: The apparatus increases the hydraulic pressure in rams 16 until one pipe moves towards a heater plate 14. The movement is detected by a limit switch 26 and a microprocessor-based control system 28 adds a pre-programmed value of pressure to that pressure which caused the movement (drag pressure). The total pressure is applied to force the pipe ends against a heater plate 14 to form end beads (bead-up). After heating for a pre-programmed period the control system automatically initiates plate retraction and forces the pipe ends together (fusion) for another programmed period. The applied pressure is the sum of the recorded drag pressure and a pre-programmed added pressure. Operator judgement of bead size, pressures and time periods is eliminated. Pressurised fluid is supplied to the rams 16 from a pump and accumulator combination. The sense of ram motion is determined by changeover valves controlled by the control system 28.
