Abstract: A socket-wrench socket is provided having a plurality of longitudinally extending members therein mounted within wall circumferential slots of the workpiece-receiving opening of the socket and secured in place by a flexible web. These members have flat surfaces for engaging the workpiece and are biased into engagement with the workpiece by the web. These members and the slots are formed such that rotation of the socket causes the slots to exert radially inward camming force onto the members at the same time that rotational force is applied to the members. The members translate the camming force to flat surfaces of the workpiece for improved gripping, and translate rotational force to the workpiece for manipulation of the workpiece in the direction of that rotation.

Abstract: A barbeque grill arrangement is provided having a grill unit removably mounted on a rack which attaches to an exterior vehicle wall to form a stable grill support solely by the vehicle connection.

Further, the linkage members are configured and mountable on the trusses so as to provide no interference with the attachment of the structural members creating the roof surface.

Abstract: A tonneau cover is provided which has at least one hinge-mounted latch adjacent the front of the cover, at least one support prop along the side of the cover intermediate the front and rear of the cover, and at least one latch mounted adjacent the rear of the cover, with a pair of independent side rails mounted to the vehicle, at least one of which contains a bracket for releasably receiving the hinge-mounted latch, a support prop receiving bracket cantilevered below and away from the vehicle side wall, and a rear catch bracket for receiving the rearward latch independent of dimensional variations induced from thermal forces over the cover. To facilitate release of the hinge-mounted latch within close confines of the front area of the vehicle bed, a self-contained trip handle is included in the receiving bracket.

Abstract: Apparatus for detecting an operating condition of a machine synchronizes sampling instants with the machine condition so that high reliability data are obtained. More particularly, an indication of the operating condition of a rotor of the machine is developed at each sampling instant. The operating condition may be, for example, the position of the rotor, in which case estimates of the rotor position and rotor velocity at each of the sampling instants are developed. Sampling signals are then derived from the rotor position and velocity estimates to synchronize the sampling instants to the rotor position.

Abstract: A template is provided for pump feet cups that is separately formed from the sump basin, positioned therein via sump basin flats to have a predetermined orientation with respect to the sump basin cover, and then attached to the sump basin to maintain a fixed position therein. A single template can be used with a variety of pump feet orientations by forming the template from a plurality of cups joined by a separable web. Foam or like material can be placed within the cups to receive the pump feet. Where the sump basin is formed from polyethylene material, the template can be molded from like material and then fixed to the lower interior surface of the sump basin by ultrasonic welding.

Abstract: A case trimming apparatus is provided having a hollow, longitudinally extending housing which is open at both ends, receiving and securing a cutting tool at one end and enclosing the cutting edge of that tool while rotatably receiving the open end of a case at its other end and retaining the case in alignment with the cutting edge. The end of the housing which receives the open end of the case includes a ledge to engage the shoulder of the case rather than engage the case by its diameter. The ledge can be removably mounted in the housing. The housing includes a chamber for retaining shavings and may include an opening from that chamber to remove shavings during trimming. Manual actuation is accomplished by rotation of the case relative to the housing while applying pressure to the case toward the cutting edge. An adapter is provided for connecting the housing to a standard power tool, such as a conventional electric hand drill, in order to provide an alternative rotary power source.

Abstract: A plumbing assembly is provided which is formed from a plurality of rigid pipe sections, connected between a movable sink and a relatively fixed fluid outlet. These pipe sections are joined together by swivel fittings that permit the pipe sections to rotate with respect to each other. In this manner, different distances between the sink and the fluid outlet are accommodated by a folding and unfolding motion of the plumbing assembly in a minimum of space behind the wall of an expandable portion of the room. Fluid supply lines for providing hot and cold water to the sink faucet can be mounted within the same spacial area by means of similar swivel fittings that create an offset parallelogram structure. The lengths of at least the fluid draining pipe sections and the supporting structure behind the wall are selected such that a downward slope is maintained over the entire fluid flow path between the sink and the fluid outlet regardless of sink position during usage.

Abstract: An apparatus is provided for femoral artery compression having an inflatable bladder, a cooling member and a rigid panel disposed within a sterile envelope and securable to a patient about the wound site via a detachable strap. The envelope can be pre-cooled as a unit and located over the wound such that the rigid panel focuses compressive force against the artery, trapping it between the panel and the pelvic bone rim. The bladder is adjustably inflatable by a conventional squeeze bulb valve arrangement and forces the cooling member against the rigid panel and the tissue in the wound vicinity. The rigid panel includes ridge structure to restrict sliding movement with respect to the cooling member. The envelope includes separate chambers for each of these components so as to restrict their movement once the envelope has been properly positioned. The envelope and its components are preferably constructed from inexpensive materials such that the entire apparatus is conveniently disposable after a single use.

Abstract: A heating and air conditioning system for a motor vehicle includes a plenum supplied with air by each of a pair of variable speed blowers. A set of heating and air conditioning ducts extend from the plenum to the drivers side of the vehicle, and another set of heating and air conditioning ducts extend from the plenum to the passengers side of the vehicle. Accordingly, both the driver and the passenger can control the blower supplying air to the ducts on the corresponding side of the vehicle. A defrosting duct extends from the plenum to supply defrosting air to the windshield of the vehicle. One of the blowers normally supplies air to the defrosting duct, but the volume and velocity of air may be "boosted" by optional use of the other blower.

Abstract: A protective cover for firearm percussion caps is provided which is removably mounted to the existing firearm nipple and secured to another portion of the firearm by an elastomeric loop. The cover has a hollow, generally cylindrical configuration formed from resilient and weatherproof material, such as rubber, and can flex off of its longitudinal axis to facilitate installation onto the nipple in close confines. A radially extending handle formed from a more rigid material is mechanically mounted to the cover between two O-rings formed from material more easily bonded to the cover. The interior of the cover is sufficiently resilient and sized so as to sealingly receive most commonly used firearm nipples via an interference fit to prevent moisture penetration to the percussion cap.

Abstract: A safelock system for removable gears is provided having a self-seating gear segment rotatably mounted on a helical ball spline for bi-directional axial movement with respect to the gear teeth to be locked. A relubrication structure is provided to service the interior of the ball spline. The interlocking teeth are two-dimensionally tapered from the point of initial engagement. Diverse biasing structures are employed to facilitate the axial self-seating reaction of the gear segment after initial engagement with the gear to be locked.
