Abstract: The present invention provides a thermally insulated cabinet for protecting electronic data storage devices from damage by accidental and environmental conditions and from intentional acts. This cabinet provides an interior envelope which contains one or more data storage devices surrounded by multiple layers of thermal insulation. The thermal insulation layers allow electrical power, data and device control cabling to access the device, thus permitting real time operation of the device while the device is contained within the inner envelope. The apparatuses include an active cooling system adapted to draw heat from within the interior space.

Abstract: A fireproof filing cabinet is disclosed. The cabinet has a shelf on which material such as files can be stored, having an open front side enclosable by a fireproof door. The door rotatably engages a retracting mechanism having a lift assist, so that the door rotates from a closed position, enclosing and sealing the shelf, to an open position, and then to a retracted position inside a compartment mounted adjacent to the shelf A lift assist mechanism enables opening and closing the door.

Abstract: A system for a vehicle includes a hollow axle, a wheel hub which surrounds the axle, bearings provided therebetween, at least one nut having a predetermined inner diameter mounted on an end of the axle, and a hub cap mounted to the wheel hub. An exciting element is mounted within the hub cap by a mounting wheel. A sensor member is mounted in the end of the axle and radially spaced from the exciting element. The sensor member has an outer diameter which is less than the inner diameter of the nut such that the wheel hub, the bearings, the nut, the hub cap, the exciting element and the mounting wheel can be removed without having to remove the sensor member from the axle.

Abstract: An anti-lock brake system (ABS) or an electro-pneumatic brake system (EBS) for a vehicle, such as a trailer, is used to perform a function of the vehicle when it is in reverse such as sounding an audible back-up alarm and/or lighting a back-up lamp. A sensor member is mounted on an axle of the vehicle is used to determine the speed of rotation of the wheel and to determine the direction of rotation of the wheel by sensing an exciting ring which rotates with the wheel. A controller processes information from the sensor member regarding the wheel speed and the direction of wheel rotation. A circuit causes the function on the vehicle to be performed when it is activated by the controller.

The proximity sensing system may be in communication with electronics and a feedback device in the trailer, such as a display device and/or a speaker. The electronics is configured to control the feedback device depending on what is sensed by the proximity sensor. Preferably, a tractor includes an engine and an electronic engine controller in operable association with the engine. The proximity sensor is in communication with the electronic engine controller, and the electronic engine controller is configured to operate the engine depending on what is sensed by the proximity sensor. The proximity sensor may be optical, microwave or ultrasonic technology based, or may be some other suitable sensor.

Abstract: A braking system, such as an Anti-Lock Brake System (ABS) or Electropneumatic Braking System (EBS), which is configured to communicate information in a wireless transmission to a remote location. The braking system may be provided on a trailer, and may be configured to communicate the information to a fleet base. The information which is communicated to the fleet base may include information regarding tire pressure and bearing health, as well as other information about the trailer. The braking system includes an Electronic Control Module, and the Electronic Control Module may be connected to a communications antenna for transmitting the information to the fleet base, or may be in communication with a Trailer Tracking system on the trailer, where the Trailer Tracking system is configured to transmit the information to the fleet base.

Abstract: A system for monitoring bearing health of a wheel of a vehicle, such as a trailer, is provided. The system is configured to monitor at least one characteristic relating to the wheel bearings, such as a temperature, vibrations, and/or proximity. The monitoring system may be configured to monitor more than one of these characteristics (i.e., temperature, vibration and proximity) or even all three. The system is incorporated into a wheel speed sensor. The system may be incorporated in an anti-lock brake system (ABS) or electro-pneumatic brake system (EBS). Regardless of which characteristic is actually monitored by the system and whether the system is employed with an ABS or EBS, the bearing monitoring system provides that one or more bearings of a vehicle can be continuously and automatically monitored in the field.

Abstract: A novel composite plate is used to form a wall or a door of a vehicle, such as a trailer or van. Each composite plate used in the trailer is formed from a pair of metal skins, such as aluminum or steel, having a foamed thermal plastic core member sandwiched therebetween. The skins are bonded to the core member by a known flexible adhesive. The foamed thermal plastic core member is resilient and may be made from foamed high density or foamed low density thermal plastic. The foaming of the core member in the present invention reduces the weight of the composite plate versus prior art solid plastic core composite plates and provides for an increased the peel strength of the composite plate versus prior art solid plastic core composite plates.

Abstract: A brake system for an air braked trailer includes a first control line for transmitting air from a source, a second control line for transmitting air, a relay valve allowing air to flow therethrough, and a pneumatic control module (PCM) having structure for reducing pressure from an inlet port of the PCM to an outlet port of the PCM. The PCM is connected to the first control line and is solely connected to the relay valve by the second control line. The first and second control lines are capable of being decoupled from the PCM and being coupled to each other to remove the PCM from the system so that a technician can check the system. An exhaust valve is integrally connected with the PCM and is capable of exhausting air to atmosphere. When the system is used on trailer, the PCM is mounted away from the relay valve, and preferably forwardly of a forward axle of the trailer.

Abstract: A novel railcar includes a floor, upstanding side walls which are connected to the floor and a top. A no slack coupler is provided for coupling adjacent railcars together to form an articulated train. The railcar includes a landing gear having a flanged wheel beneath a forward portion thereof and a bi-directional bogie mounted beneath a rearward portion thereof. The landing gear and bogie can be used to support and move the railcar on railroad tracks. Structure is provided for attaching a dolly adaptor to a rear end of the railcar and for connecting a tractor to a front end of the railcar. The railcar can be easily detached from the remainder of the articulated train, moved off of the tracks and transported around a rail yard by the tractor and the dolly adaptor so that the railcar can be loaded at a dock. Thereafter, the railcar can be easily reattached into the train on the track.

Abstract: A railcar which forms part of an articulated train includes a novel deck system and a novel, low-level, low-profile, no slack coupler. The railcar is formed from a floor, upstanding side walls which are connected to the floor and a top to form an enclosure. The deck system includes an upper deck and a lower deck which are connected together and are counterbalanced against each other. The decks are movable to a first position wherein the decks abut against each other so that cargo, such as automobiles, general freight and the like, can be loaded onto the upper deck and onto the floor. The decks are movable to a second position wherein the decks are spaced apart from each other so that cargo can be loaded onto the upper deck, the lower deck and the floor. In several embodiments of the novel deck system, the decks can be moved relative to the floor when the decks are in the first and second positions.
