Abstract: A retarding system for a work machine having a power source, a transmission, and a manually operated braking mechanism is disclosed. The retarding system has an engine retarder associated with the power source and a controller in communication with the transmission, the manually operated braking mechanism, and the engine retarder. The controller is configured to determine a deceleration rate of the work machine and compare the deceleration rate of the work machine to a predetermined threshold rate. The controller is also configured to determined if the manually operated braking mechanism is active and to cause the transmission to downshift if the deceleration rate is less than the predetermined threshold rate and the manually operated braking mechanism is determined to be active. The controller is further configured to prevent the transmission from downshifting if the deceleration rate is less than the predetermined threshold rate and the manually operated braking mechanism is determined to be inactive.

Abstract: A transmission has only a single, minimal orbiter in which an input gear and an output gear, each being connected to separate input and output shafts, are interconnected through an orbiting cluster gear that meshes with only the input and output gears. The cluster gear is carried by a web that is itself rotated by a hydraulic control motor through a first clutch. When rotation of the web is prevented, rotation of the input gear produces rotation of the output gear at a predetermined reduction of the input drive, this gear reduction being continuously diminished proportional to the speed of rotation of the web in a first direction. When the vehicle reaches highway speeds, the control motor is disconnected and a second clutch is activated to connect a predetermined overdrive that is located between the engine drive and the transmission rather than being conventionally positioned between the transmission and the final output shaft.

Abstract: A computer system having a hard disk drive and a video display device, includes a RAID card having an interface controller and a RAID controller. A motherboard is constructed with a central processing unit, a system bus, a SCSI controller and edge connectors for the mounting of the RAID card, and when the RAID card is mounted in the edge connectors, the RAID controller is connected to the system bus via the interface controller so that the RAID card inputs and outputs data to and from the CPU. The RAID controller is connected to the hard disk drive through the SCSI controller, thereby providing RAID capabilities for the computer system.

Abstract: The chain drive described in the present disclosure, instead of using a single sprocket wheel, saves space by making use of two or more sprocket wheels coupled together by slip-free means, each sprocket wheel having only a small number of low sprockets. The number of sprocket wheels, the center-to-center distance between the sprocket wheels, the tip diameter of the sprocket wheels, and the phase offset of the sprockets as between the sprocket wheels which form a set of such wheels are all so matched that one sprocket of one sprocket wheel always engages in the chain in rhythmical sequence, so that all the sprocket wheels rotate smoothly when the chain moves evenly.

Abstract: A center differential for a four-wheel drive vehicle comprises three members, i.e.: an input member rotatably connected for rotations to the output shaft of a transmission; a first output member for transmitting rotation of the input member to a rear wheel output shaft; and a second output member for transmitting rotation of the input member to a front wheel output shaft. Frictional engaging elements are interposed between any two of those three members, and a applying force transforming device for generating a force to engage the frictional engaging elements on the basis of a tangential force which is generated relatively between any of the three members are also provided.

Abstract: A power transmission that uses inertia forces. The drive member carries a urality of high density rollers that are acted on by centrifugal force. The driven member includes reaction surfaces that periodically move the high density rollers inwardly in opposition to the centrifugal force. As the rollers are moved inwardly they impart energy to the driven member, thereby producing a power transmission action. The reaction surfaces on the driven member are designed so that the system is responsive to speed and load changes.

Abstract: An improved amusement or game device of the type which has one or more indicia-bearing rotatable reels which are rotated upon initiation of play by a player is disclosed. The game device has an improved main drive mechanism which permits the player to vary the initial rotational speed of the reels in direct proportion to the speed in which an associated operating handle is pulled. A supplemental drive mechanism is included for increasing the speed of the reels if the player fails to pull the operating handle with sufficient force to rotate the reels at a predetermined minimum speed. The device also includes an improved indexing means for stopping the reels in accordance with the operation of the game device. The game device also includes means for absorbing excessive energy that may be provided by a player pulling the operating handle with extraordinary speed or force.
