Patent EP-0023795-A1 (EP)
Inventor: BLAZEK WILLIAM STEPHEN
IPC: B22C7/02
Filed: 1980-07-23
Abstract: A plurality of mold wall segments (26) are positioned in a circular array (80) in an adjustable fixture to form a mold assembly (22). The fixture (54) includes a base with a plurality of upstanding pin members (50). Two of the pin members (50) engage the bottom portion of each mold wall segment. Each pin member is eccentrically mounted on a disc. By rotating the discs relative to their base, the mold wall segments may be moved inward or outward. This movement varies the diameter of the lower portion (22) of the mold assembly. The pin members have threaded end portions which enable the pin members to be moved along their upstanding central axes. This movement varies the height of the lower portion of the mold assembly. In addition, the fixture includes a plurality of radially extending adjusting rods (82), each rod engages a radially inner side (90) surface of a mold segment. By moving the rods radially inward or outward, each mold segment is caused to tilt or rotate about an axis extending through the upper end portions of the pin members (50) which engage the bottom portions of that mold wall segment. This movement varies the diameter of the upper portion of the mold assembly. In one embodiment of the invention, the mold segments of inner and outer annular arrays of mold segments are independently movable relative to each other.

Title: Object and people counting system.
Inventor: MOTTIER FRANCOIS M
IPC: G07C9/00
Filed: 1981-05-04
Abstract: The perimeter of an area is scanned along two adjacent paths which define spacially resolved gates through which objects and people must pass to enter and leave the area. As the gates are scanned, the presence of objects and people are detected. A complete scan produces a gate signature which includes information indicative of the presence and location of objects and people in each gate during the scan. Successive signatures are compared in sequence as scans are made in order to determine changes caused by movement of objects and people in or out of the area. From this comparison an up/down counter is controlled to maintain a dynamic count of the number of objects or people in the area following each scan of the gates. The counter counts up as objects and people enter the area and counts down as they leave.

Abstract: Systems described may be used in shock or motion absorbing devices, acoustic lenses, loudspeaker enclosures, etc. For a loudspeaker enclosure a sealed bag 50 of flexible plastics film contains a folded woven support 54 carrying surgical cotton layers 58 on its faces. The support 54 and layers 58 are wetted with a mixture of water and low boiling point Freons (T.M.) and sealed in the bag 50 with air. The fibres and the water serve as heat sinks interacting with the acoustic energy and interchanging heat of vaporisation and condensation with the low boiling point liquid. The volumetric compliance of an enclosure containing such bags is significantly increased especially with a spatially distributed mass of fine fibres disposed in thin layers separated by communicating channels.

Abstract: A power shutdown control valve assembly (35) is disclosed for use with a hydrostatic transmission. The valve assembly includes a housing (61) defining a poppet chamber (111, 119) and a valve seat (121). A poppet member (141) is disposed in the poppet chamber and defines a biasing chamber (147) and a poppet surface (145). When the poppet member is closed, the poppet surface includes first and second poppet areas (151, 153) exposed to the fluid inlet (123) and the fluid outlet (65), respectively. A spring means (149) urges the poppet member toward the closed position, but when system pressure acting on a first differential area (151 minus 155) overcomes the force of the spring, the poppet member moves away from the closed position and the second poppet area is also exposed to system pressure, thus biasing the poppet member to its open position. In the open position, the flow path from the inlet to the outlet past the valve seat is restricted sufficiently to maintain a predetermined minimum pressure upstream of the valve seat, while permitting full system flow past the poppet member to the low pressure side of the system. As a result of the present invention, the pump output flow bypasses the motor, but is maintained at the relatively low minimum pressure, rather than at the relatively high relief setting, thereby substantially reducing the amount of power consumed, and heat generated, during operation in the relief or shutdown mode.
