摘要:
A rotor housing assembly is adapted such that a barrel valve is arranged to regulate the flow of fuel/air mixture both from outside the housing assembly into an internal lubrication flow path and from the internal lubrication flow path into an internal chamber. The barrel valve includes a substantially cylindrical valve member diagonally traversed by a separation plate, dividing the interior of the valve member into an inlet chamber and an outlet chamber. Fuel/air mixture entering the housing assembly from outside passes through the inlet chamber and fuel/air mixture entering the internal chamber passes through the outlet chamber.

A device for measuring force of bending of a head-flexure assembly including a load cell with a cell reference surface slidably mounted on a base having a reference surface, a shaft threaded into theload cell with a first thread and threaded into the base with a second thread so that by turning the shaft, the distance between the two reference surfaces can be very accurately adjusted providing that the device can be calibrated to an accuracy of less than ten milligrams.

A method for synchronizing transmitters within a communications network by utilizing wide-mode marshaling. Wide-mode marshaling increases the bandwidth dedicated to performing a marshaling process, thereby allowing a controller to quickly marshal the transmitters. Within a TDMA network, a TDMA frame includes a header portion and a multi-channel portion. Each of the transmitters within a TDMA network transmits during an assigned time-slot of the TDMA frame. To marshal a transmitter, the transmitter is requested to transmit a ranging signal to a central controller. If the ranging signal is received during the header portion of the TDMA frame, the controller can accurately detect the ranging signal. However, for longer propagation delays, the length of the header is insufficient. Wide-mode marshaling resolves this by silencing some or all of the transmitters to increase the bandwidth for receiving the ranging signal.

A retractable needle assembly is disclosed. The needle assembly consists of a syringe body, having a needle assembly on one end and a plunger assembly on the opposing end. The needle assembly, which enables and disables fluid communication between the needle and fluid reservoir, comprises a generally cylindrical body sealably disposed within the lower interior of the syringe body. The cylindrical body is rotatable, facilitated by a knurled ring, within the syringe body. Rotation of the cylindrical body causes either enablement or disablement of the needle assembly. Tabs, located on the syringe body are received within notches, separated by one-way and two-way ramps, located on the cylindrical body, such that the ramps facilitate either temporary or permanent disablement of the device. Plunger lock means are also disclosed.

A disk/file for magnetic recording having overall dimensions of one quarter inch thick by about the size of a standard credit card with pin connectors for connecting into a receptacle such as for pc boards. The file features a multi pole rotor mounted on the rims of two disk and a stator divided external to and coplanar with the disks. An actuator features a "wobble" disk rolling around the inside of a nest of electromagnets and turning a small increment with such excursion around the nest thereby turning the shaft of the head support to actuate the head from track to track. The head support arm includes two sections hinged together and engaged with a third link that orients the head to eliminate head skew. A magnet withdraws the head devices from the disk surface to avoid sticktion when the disks are stationary. The head devices feature thin film cores that are oriented flat to the surface of the disk.

摘要:
A device for measuring force of bending of a head-flexure assembly by a given amount characterized by the distance between a clamping surface for one end of the flexure and the plane (recording surface) in contact with the head at at the other end of the flexure. The device includes a load cell with a cell reference surface adjustably supported on a cell base which is slidably mounted on a main base. Adjustment of the location of the cell reference surface with respect to the clamp surface is achieved by a shaft threaded into the load cell with a first thread and threaded into the main base with a second thread so that by turning the shaft, the distance between the two reference surfaces can be very accurately adjusted. When the load cell is deformed by application of the head loading force to the cell reference surface, a signal from the load cell actuates a mechanism maintaining the cell reference surface in its initial location thereby maintaining the initial flexion of the flexure.
