    Abstract: Door operator for commercial and domestic use with swing-mounted doors are disclosed. Each operator employs a variable-speed d.c. motor as prime mover, and a vertically oriented door-driving operator output shaft journalled in a transmission having a compact transmission housing which includes shock mounts for mounting of the transmission housing and operator within structure associated with the door. The transmission provides speed reduction coupling of the motor drive shaft to the operator output shaft with substantially right-angled relationship between their axes of rotation. The transmission includes a drive gear, to which the motor drive shaft is coupled by miter gear arrangement of different types, with the drive gear in coaxial relation with the operator output shaft but independently rotatable about it. Epicyclic sun-and-planet gear drive mechanism of specialized design is coaxial with the operator shaft and includes planet gears driven for epicyclic movement about the axis of the operator output shaft, providing speed reduction coupling of the drive gear to the output shaft. Different possible spring arrangements, including rack-gear operated spring modules of interchangeable character, are used for resiliently coupling restorative force to the operator output shaft upon rotation thereof in at least one direction.

    Abstract: A ball check valve is described having a fluid port, a ball moveable toward and away from the port, a seating surface surrounding the port and an elastomeric sealing element. The seating surface has a conical annular surface extending radially outwardly away from the ball and an annular ridge between the port and the conical surface. The sealing element has an outer sealing surface for contacting the conical seating surface and an annular groove for receiving the seating surface ridge. On its ball side, it has an annular outer surface and an inner sealing surface for contacting the ball. A sealing element retainer contacts the outer portion of the elastomeric sealing element outer surface on its ball side to hold it in position.

    Abstract: An access control apparatus for an access gate. The access gate typically has a rotator that is configured to rotate around a rotator axis at a first variable speed in a forward direction. The access control apparatus may include a transmission that typically has an input element that is operatively connected to the rotator. The input element is generally configured to rotate at an input speed that is proportional to the first variable speed. The transmission typically also has an output element that has an output speed that is higher than the input speed. The input element and the output element may rotate around a common transmission axis. A retardation mechanism may be employed. The retardation mechanism is typically configured to rotate around a retardation mechanism axis. Generally the retardation mechanism is operatively connected to the output element of the transmission and is configured to retard motion of the access gate in the forward direction when the first variable speed is above a control-limit speed. In many embodiments the transmission axis and the retardation mechanism axis are substantially co-axial. Some embodiments include a freewheel/catch mechanism that has an input connection that is operatively connected to the rotator. The input connection may be configured to engage an output connection when the rotator is rotated at the first variable speed in a forward direction and configured for substantially unrestricted rotation when the rotator is rotated in a reverse direction opposite the forward direction. The input element of the transmission is typically operatively connected to the output connection of the freewheel/catch mechanism.
