摘要： A stamped hardened sheet steel tapered ferrule with cantilevered radially resilient fingers is wedged by a spring against a tapered bore of a hardened steel housing. The fingers bend radially inwardly to grip a stranded steel cable in the ferrule bore in response to the spring action. When the cable is slid in the ferrule in one direction, the ferrule gripping the cable is further wedged against the tapered bore and further grips the cable. The cable is released when it is slid in the opposite direction pulling the engaged ferrule away from the tapered bore of the housing. The cable has a flag at one end which with the seal lock a hasp therebetween limiting the relative motion of the cable in the opposite ferrule release direction. In a second embodiment, the ferrule is in interference fit with a rod or cable and the spring is not used forcing the ferrule to always grip the rod or cable. The ferrule in both embodiments grips the softer cable with higher rotational force than the ferrule friction force with the housing bore so that rotation or twisting of the cable relative to the housing rotates the ferrule therewith. The cable can not be threaded out of the ferrule by rotating the cable. A lubricant or reduced friction material coating can be used to enhance relative rotation between the ferrule and housing.

摘要： An air spring load monitoring system provides a vehicle operator with an on-board visual display of the load distribution imposed on each axle from front to rear of a truck and trailer, and displays differential loads imposed from side to side across each axle as a result of local overloading caused by unequal load distribution. Pneumatic transducers produce analog output signals proportional to the internal air pressure of each air spring as an accurate indicator of payload distribution. Load data is presented by load display groups in which visual display elements are positioned in spaced relation along a scale representative of a predetermined air spring load range. The visual display elements of each group are positioned in side by side relation for visual comparison to each other and to the scale. Each visual display element is representative of a predetermined load range increment. A signal conversion circuit drives a predetermined visual display element in each display group which corresponds with the load range increment containing the air spring load value represented by the analog output signal.

摘要： A lock body through bore receives a steel bolt with an array of annular grooves. A locking mechanism secured in the bore has an annular array of locking jaws normally biased engaged with an inserted bolt groove. A jaw spreader has a conical surface for spreading the jaws radially outwardly to disengage the bolt. A locking member normally is radially outwardly of the jaws to preclude such spreading. A spring with a high spring constant, e.g., 300 pound load, axially biases the locking member in the jaw locking position. The spreader and locking member define a locking jaw conical path for radially outwardly releasing the jaws during bolt insertion and for locking the jaws in the opposite bolt withdrawal direction. A manually operated tool with a rotatable cylinder which engages the spreader and including a pair of lock gripping tines provides a high force to the spreader to axial displace it against the locking member spring to release the bolt locking jaws while simultaneously radially outwardly releasing the jaws from the bolt.

摘要： A plurality of walls form a housing cavity in which a latch hasp is received. An opening in the housing receives therethrough the latch hasp, the latch enclosing the cavity. The bolt seal has a shank with a head at one end or with a U-shaped bight in a second embodiment. The head engages a housing wall and a locking body engages and locks to the shank at a shank end distal the head. The shank between the head and lock body is fully enclosed by the housing and latch to preclude access to the shank by tampering tools. In a second embodiment, the shank bight engages the received hasp of a latch. The shank distal the bight is locked to the housing by a locking body. The latch depends into and encloses the housing cavity open at the top. The shank between the bight and the locking body is fully enclosed in the cavity. Different housings are disclosed wherein the head may be enclosed or exposed for access by a shank breaking tool. A reusable bolt and locking body is disclosed for use with several embodiments.

摘要： A molded transparent thermoplastic housing has a programmable transmitting circuit for transmitting seal identifying serial number, seal location, container identification and other data to a local receiver. A door in the housing permits access to the circuit for programming the seal indicia and related data for transmission. A contact arrangement forms a switch upon insertion of a locking bolt into a locking mechanism in the housing and applies battery power through the bolt to activate the data generating circuit. A conductor along the bolt shank is connected to the circuit provides a tamper evident signal to the circuit when the bolt is severed. The circuit senses the removal of the bolt or severed bolt condition for generating a “tamper” signal which is transmitted to a local receiver/reader. The conductor at the bolt may be a wire in a plastic tube surrounding the shank, a conductive layer over an insulation layer on the shank and over the conductive bolt head in ohmic contact with the head or a wire in a hollow metal tube. Severing the bolt severs the wire or the ohmic contact between the head and coating or between the head and the wire in the tube to indicate tampering. The seal periodically in random periods transmits the seal condition, whether normal or tampered. In an alternative embodiment, an interrogation unit may interrogate the seal which then transmits its locked or tampered states according to the locked or tampered condition of the bolt.

摘要： Apparatus for injecting coolant into the fuel-air mixture supplied to a turbocharged internal combustion engine in which coolant is stored in a reservoir that is connected to the outlet side of a turbocharger compressor and is pressurized during times that the turbocharger is generating positive pressures above a predetermined level. The pressure in the reservoir forces coolant to the inlet side of the turbocharger to cool fuel and injection is interrupted when the pressures are below that level and cooling of the fuel-air mixture is not required.

摘要： A weight measurement method and apparatus for measuring and monitoring the weight load on a vehicle such as a tractor trailer rig. A load pin and bearing assembly mechanically couples the weight of a trailer and its payload to the leaf springs of a tractor trailer truck. The shackle pin is intersected by a longitudinal bore in which multiple strain gage sensors are mounted. A miniature signal processing unit is totally enclosed and shielded within the longitudinal bore and is electrically connected to the strain gage sensors. The signal processing unit develops weight signals that are communicated by conventional low voltage signal cabling to a load display unit in the tractor cab. An offset lubricant passage provides a means for lubricating the load pin bearings while preventing contact of the lubricant with the strain gages, internal wiring and signal conditioner components housed within the main longitudinal bore.
