Title: Truck sleeper cab to day cab conversion kit assembly
Inventor: REED DONALD MICHAEL
IPC: B62D33/06
Filed: 2003-10-28
Abstract: A conversion kit assembly for converting a sleeper truck cab with a modular sleeper/cab into a day cab includes a sleeper truck cab including a rear sill, two laterally spaced walls, and a roof, with each of the walls having a B-pillar assembly at a rearward end of the sleeper truck cab. The B-pillar assemblies are coupled together at their upper ends by the roof, and at their lower ends by a lower member such as a lower panel or a rear sill such that the rearward end of the sleeper truck cab is substantially square. The sleeper truck cab further has,a plurality of attachment points at the rearward end for attaching the modular sleeper. A  first plurality of fasteners, which connect the modular sleeper to the sleeper truck cab, are removed. The modular sleeper is removed from the sleeper truck cab thereby creating a rearward opening at rearward end of modular truck cab. A closeoff panel assembly comprising a frame sub-assembly and an outer panel welded to the frame sub-assembly is then attached to the sleeper truck cab by fasteners disposed at locations corresponding to at least some of the plurality of attachment points. The closeoff panel assembly is provided to close the rearward opening created by removal of the modular sleeper from the sleeper truck cab. First and second reinforcement members connect the closeoff panel assembly to the B-pillar assemblies of the sleeper truck cab, and third and fourth reinforcement members connect the closeoff panel assembly to the lower panel or rear sill of the sleeper truck cab, to distribute loads from the closeoff panel to the sleeper truck cab, and thence to the vehicle chassis. A load is distributed from the closeoff panel assembly to the sleeper truck cab with the reinforcement members. A gasket is also used between the sleeper truck cab and the closeoff panel assembly to seal moisture from the cab.

Title: Temperature control system for air/oil shock absorber module
Inventor: WEBER ARNETT R
IPC: B60G15/14
Filed: 2003-11-12
Abstract: A module consisting of a shock absorber and an air spring is provided with a control for avoiding an undesirably high temperature within the air spring. In particular, a temperature responsive valve is mounted on the air spring, and is operative when the temperature of the air spring reaches a predetermined level. At that point, the temperature responsive valve opens, allowing flow of air outwardly of the air spring. A source of cooler air is also associated with the air spring.  In particular, a leveling valve opens to deliver air into the air spring, when the air volume within the air spring decreases due to opening of the temperature responsive valve. Thus, a cooler air is delivered into the air spring. The control thus automatically maintains an acceptable temperature in the air Spring, even when the shock absorber reaches very high temperatures.

Abstract: A method of disposing materials such as pet waste. First, an assembly is provided that has a container; a fitting for accepting and retaining a garden hose; a pressure nozzle for receiving water from the fitting and expressing the water under pressure; and a nozzle-retaining apparatus oriented so that the water expressed is directed into the container at an angle adapted to produce a churning motion within the container. Biodegradable material is placed into the container and the insertive coupler of a standard garden hose is attached into the fitting. Finally the faucet is turned on to cause water to flow through the hose and out the nozzle thereby watering and stirring and fragmenting the biodegradable material while the operator remains at a distance far enough away from the container to avoid the unpleasant odor that is emitted from the container by virtue of the watering and stirring and fragmenting.

Abstract: An iterative multiplier circuit (10) comprises modules (15 to 18) that subdivide the respective input signals (Zn, Jn) into a first part (msb(Zn), msb(Jn)) that is the power of 2 immediately lower or equal to the input sign al and a second part (Zn-msb(Zn), Jn - msb(Jn)) corresponding to the difference between the input signal and the aforesaid first part. A shift module (19) generates a respective output signal through shift operations that implement the multiplication operation for numbers that are powers of 2. The circuit operates according to a general iterative scheme in which at each step three components of the output signal (X.Y) are computed, corresponding to the product of two numbers that are powers of 2 and to two products in which at least one of the factors is a power of 2. The number of steps in the iterati on scheme is controllable, thus allowing to vary the accuracy with which the output value (X.Y) is calculated.

Abstract: To achieve a large thickness of conductive metal-containing material in a feature of a product unit processed with a liquid-based etch process, the desired thickness of material is apportioned to the two opposing surfaces of a substrate to create a two-part feature. Conventional features are made by identically patterning two same-thickness metal-containing layers and electrically connecting the resulting patterned parts in any suitable manner . However, features may also be made that do not have identical parts on opposite sides of the substrate, the two parts being electrically connected but differing in thickness, in shape, or both. Moreover, having two metal- containing layers separated by an insulator is also useful for allowing different sections of the same feature or circuit to cross one another witho ut shorting, or to overlap in whole or in part without shorting. A polymer substrate (1004), e.g. polyethlyene terepthalate, is covered on the top and bottom surfaces by a metal- containing layer, e.g. aluminium or copper foil, which are in turn covered by etch masks (1110, 1120, 1130, 1140, 1150, 1160, 1180), e.g. a resin formed by gravure printing or photoresist. The web is immersed in a bath or sprayed with an etchant, e.g. NaOH, to form the metal- containing web (1115, 1125, 1135, 1145, 1155, 1165, 1175, 1185).
