Abstract: The invention provides exemplary systems and methods for releasably securing a data storage device within a data storage system. In one exemplary embodiment, the invention comprises a cabinet which defines an enclosure. The data storage device is removably held within the enclosure. A cover is further provided which comprises a pivot end and a latch end. The pivot end is pivotally attached to the data storage device so that pivoting of the cover will release the data storage device at least partially from the enclosure. A cover latch is operably attached to the latch end, with the cover latch engaging the data storage device to prevent pivoting of the cover when the cover is closed.

Abstract: A modular cabinet for enclosing a plurality of disk drive canisters. The cabinet includes left and right sides and a center section, each formed of molded structural foam. Each side includes horizontal top and bottom portions which include tongue-like projections for mating with similar features in top and bottom portions of the center section. The sides and center section are secured together through the use of four latching members which cooperate with features molded into the sides. The design of the components permits easy assembly of the cabinet without the use of tools. Horizontal rails molded into the internal surfaces of the sides and both surfaces of the center section form the bays for receiving disk drive canisters.

Abstract: This invention is a magnetic clutch brake mechanism operable to achieve either a clutch or a brake function and can be installed, for example, on a lawn mower apparatus to selectively control the rotating movement of a lawn mower blade member. The magnetic clutch brake mechanism includes: (1) a main actuator assembly; (2) a drive rotor assembly which is connected to a main drive shaft for rotating same; (3) a clutch plate assembly operably connectable to the drive rotor assembly; and (4) in this case, a blade mount assembly to receive a rotatable lawn mower blade that is securely fastened thereto. The main actuator assembly includes an actuator bracket member which is connected to an actuator ring member that is selectively movable axially about the drive rotor assembly and the clutch plate assembly to alter a magnetic field therein. The drive rotor assembly includes a rotor member which is driven by a gasoline or electric motor in order to rotate same at a desired speed.

Abstract: A variable flow reversible vane pump having a rotor with slidable vanes, a shaft providing rotary power take off for the rotor and a cam ring wherein said rotor rotates with the vanes engaging the inside of the cam ring. A case encases the cam ring and a front bearing plate connects to the front of the case. A rotary valve surrounds the shaft and flushes against the cam ring and the rotor with slidable vanes and has a structure defining a plurality of directly opposed channeled arcuate grooves, at least one port in each of the opposed grooves, and a plurality of gear teeth along part of the periphery. A rear bearing plate encloses the other end of the cam ring and the rotor and has a structure with rear plate apertures in communication with one of the opposed arcuate grooves and the port therein of the rotary valve plate. A rotatable gear is lodged within a gear channel of the case and meshes with the gear teeth along the periphery of the rotary valve plate.

Abstract: Apparatus of increased simplicity, reliability and economy is provided for automatically maintaining the tautness of a mechanical coupling such as commonly employed, for example, between a vehicular brake and its actuating mechanism, which would otherwise be subject to loosening during normal use as a result of wear or the like. The apparatus, although also utilizable with mechanical couplings employing rigid connecting links, is especially suited for use with couplings employing flexible cables or the like, wherein it need only be interposed in series with the cabling between the actuating mechanism and the device actuatable thereby, thereby adapting the apparatus for use in a variety of applications in which control cable couplings are employed.

Abstract: A manually operated, cable control lever assembly especially adapted for use with a handlebar grip is provided with an elongate lever having one end thereof pivotally mounted to a support bracket which also restrains the movement of the control cable in a direction generally aligned with the lever. The lever is provided with: an essentially straight, internal cavity extending longitudinally therethrough and providing a first access opening in the free end of the lever; an attenuated, internal passageway in communication with the cavity and diverging away from the latter toward the free extremity of the lever and terminating in a second, recessed access opening; and, an access slot extending between the access openings and into the passageway.

Abstract: A twistable type throttle-grip assembly especially adapted for use with motorcycle-like vehicles manipulates a single control cable and is normally operational in a first rotational range for controlling the supply of fuel to the vehicle's internal combustion engine thereby controlling the vehicle's speed and is provided with an integral latch mechanism which may be operated by the thumb of the operator while holding the hand grip to release the hand grip for rotation into a second rotational range associated with the operation of a cable controlled, combustion cylinder compression release device on the engine to turn off the latter and permit manual pedaling of the vehicle.

Abstract: This invention relates to a wire matrix printer system using a plurality of unique print wire actuator mechanisms operable to print dots on a printing medium. The novelty is in each print wire actuator mechanism using an electro-mechanical combination including (1) a print wire actuator; (2) a permanent magnet collector; (3) a solenoid collector; and (4) a connector assembly holding the aforementioned together as a unit. The print wire actuator includes a print wire assembly having a wire member moved through a printing stroke under the unique combined force of (1) a torsion rod, and (2) a solenoid member. Additionally, the wire member is returned to the rest or starting position under the force of the torsion rod and a permanent magnet collector member.

Abstract: A vibratory plow suitable for laying flexible cable, pipe and the like underground. The vibratory plow assembly includes a frame which supports the assembly on a tractor, bulldozer or other vehicle, a vibrator and a plow. The vibrator includes a housing and a rotating eccentric weight assembly which imparts an oscillatory motion to the vibrator housing about a neutral axis having a varying and reversing moment. The vibrator is supported on the frame by resilient bearings in the neutral axis of the vibrator and the plow is supported on the vibrator housing spaced from the neutral axis to impart vertical vibration to the blade. The first embodiment includes a blade on each side of the neutral axis, such that the blades are vibrated in opposite directions to impart a shearing action. In the second embodiment, only one blade is utilized and a counterweight is supported on the vibrator housing to counterbalance the blade.

Abstract: An incremental digital control system to effect incremental adjustments to an operating system. The control system is responsive to selective relationships between digital signals representative of operational characteristics for producing changes in control signals to effect the desired incremental adjustments.

Abstract: An actuator for a wire matrix printer including a plunger which is mounted in a frame for reciprocal movement between first and second positions therein, and the plunger has a print wire fixed thereto by a special swaging technique. The plunger is moved to and held in the first position against the bias of a special spring by a permanent magnet. When the actuator is to be fired, a neutralizing coil is energized to nullify the holding effect of the magnet, enabling the spring to accelerate the plunger towards the second position (towards a platen). The spring is disconnected from the plunger after it is accelerated, enabling the plunger and print wire attached thereto to travel ballistically at least part of the way to the second position from the first position.
