Abstract: A support structure for supporting and tilting an oversized cargo to reduce the effective width of the cargo. The structure comprises a bolster frame having a base and a stanchion connected to the base. The stanchion extends upwardly from a lower end connected to the base to an upper end opposite the lower end. A cylindrical roller supported is by the upper end of the stanchion for rotational movement relative to the stanchion about a rotational axis. The cylindrical roller is also supported by the stanchion for pivotal movement relative to the stanchion such that the rotational axis pivots relative to the stanchion. The bolster frame also includes a bearing pad connected to the base. The cylindrical roller and the bearing pad at least partially support the oversized cargo. The support structure may be mounted on a trailer for transporting oversized cargo, such as concrete double-tees.

Abstract: A method of reducing the effective width of cargo, such as a concrete double-tee. The method comprises positioning the arm in a first position in which the arm is substantially horizontal, the arm being pivotally biased toward the first position, lowering the double-tee onto the arm such that the first leg of the double-tee is received by the first bracket and the second leg of the double-tee is received by the second bracket, and pivoting the arm and double-tee to a second position in which the second end of the arm contacts the base to support the arm, the arm being biased toward the second position when the arm supports the double-tee. The concrete double-tee includes a deck, a first leg and a second leg. The support structure includes a base, a stanchion extending upwardly from the base, an arm pivotally connected to the stanchion and extending between a first and second end. The arm includes a first bracket disposed near the first end and a second bracket disposed near the second end.

Abstract: A drying apparatus, and in particular, a hand dryer that comprises a first compartment and a second compartment. The first compartment comprises an inlet for allowing air to enter the first compartment and a germicidal tube mounted in the first compartment for sterilizing air in the first compartment; while the second compartment comprises a heating element for heating sterilized air in the second compartment and a blowing unit for causing sterilized air in the second compartment to rapidly exit the second compartment and out of the hand dryer. A fan is provided for causing sterilized air to leave the first compartment and enter the second compartment. In this way, the sterilized air that exits the second compartment and out of the hand dryer is at least essentially free of airborne microorganisms.

Abstract: A support structure for supporting and tilting an oversized cargo to reduce the effective width of the cargo. The structure comprises a frame having a base and a stanchion connected to the base. A rocker arm is pivotally coupled to the stanchion to pivot about a pivot axis. The arm includes a first and second end disposed opposite one another. The arm has a center of gravity disposed between the first end and the pivot axis and that biases the arm to pivot in a first pivotal direction. First and second brackets are positioned near the first and second ends of the arm for receiving the cargo. The cargo has a center of gravity disposed between the pivot axis and the second end that causes the arm to pivot in a second pivotal direction opposite the first pivotal direction.

Abstract: First and second concrete sections connected to one another. The first concrete section has a first side and a first edge at least partially embedded in the first side. The second concrete section has a second and a second edge at least partially embedded in the second side. The first and second concrete sections are positioned adjacent one another with the first and second edges being elongated and relatively straight and extending adjacent one another. The first and second edges are substantially evenly spaced from one another along the sections. The first and second edges are formed from a plastic material. A continuous weld is formed between the first and second edges and extends along the length of the edges and connects the first section to the second section. The weld is formed from a semi-flexible plastic material and resists materials from passing between the edges.

Abstract: A pre-formed concrete section comprising a deck and first and second legs extending from the deck. The deck includes a first side, a second, and a width extending between the first and second sides. The deck also includes a top surface, a bottom surface, and a thickness extending between the top and bottom surfaces. The distance from the first leg to the second leg is more than two times greater than the distance from the first side to the first leg. The width of the deck is more than four times greater than the distance from the first side to the first leg. The thickness of the deck decreases as the deck extends outwardly from the first leg toward the first side. The thickness of the deck decreases as deck extends outwardly from the second leg toward the second side. A platform including multiple sections includes unevenly spaced legs.

Abstract: A hand dryer 2 consists of an outer housing with a main fan 8 which draws air into the housing and out of a first outlet 12 on operation by a user. The dryer 2 also incorporates a substantially constantly operated second fan 22 which provides a substantially constant sterilising air flow.

Abstract: A satellite stabilization system compensates for the destabilizing torque introduced by solar radiation pressure by the emplacement of tabs of material angled relative to the back surfaces of the antenna reflectors to intercept solar rays. The material of the tabs interacts with the solar radiation in substantially the same manner as the interaction of the material on the back surface of each antenna reflector to produce a radiation pressure and consequential increment in a torque about an axis of the satellite. Each of the tabs is constructed in the manner of a plate or disk, and is attached by means of a spring mount to the back surface of one of the reflectors. The reflectors are angled relative to each other, as well as to a body of the satellite which holds feeds for illuminating the reflectors, for directing beams of radiation from the feeds towards the earth.

Abstract: A method of detecting a deflated tire on a vehicle which includes sensing the angular velocity of each wheel and producing a signal proportional thereto, processing the four signals in a processor unit which subtracts the sum of the signals from one pair of diagonally opposite wheels from the sum of the signals from the other pair of diagonally opposite wheels, sensing when the magnitude of the result is between 0.05% and 0.60% of the mean of the two sums, comparing the signals for each of the four wheels in turn with the signals for each of the other wheels, sensing when one of said signals is different from the average of all four signals by more than 0.1% and in the event of both sensed signal factor being present, operating a warning device to indicate a tire is partially or completely deflated.

Abstract: A vehicle wheel rim is disclosed a pair of bead seats, and axially inwards of and adjacent to each bead seat a circumferentially extending tire toe engaging groove. There is a secondary bead retaining means between the bead seat and the groove comprising a hump having a height measured radially from the bead seat surface adjacent to the hump of 1 to 3.0 mm. The hump preferably has a steep surface on its axially outer edge. The resultant wheel still correctly seats a normal tire with the toe engaging the hump when the tire is deflated and correctly engages in a TD type of tire with the toe in the groove.

Abstract: A tire is disclosed, including a tread portion, sidewalls and a pair of beads each containing a substantially inextensible annular bead core, having a bead seat and an extended toe portion. The extended toe portion includes an elastomeric material, extending lengthwise from the bead core in a direction radially and axially inwards thereof, the toe of a rigidity in the direction of its length such that in use of the tire on a wheel rim having a groove complementary to the toe and engaging the toe when an axially inward force is applied to the tread portion, a radially and axially outwardly directed force is generated at the bead core to affect bead retention. The toe has a substantially continuous, circumferentially extending toe decoupling means at the junction of the tire bead seats and the toe so that the toe is effectively decoupled from the bead in bending of the toe axially inwards of the tire. The decoupling means may be a single cut of a small groove.
