Abstract: A vehicle discharge system for a vehicle (1) provided with a rearwardly tippable bed (2) which includes a tailgate (3) comprises a housing (5) mounted at the rear of the bed (2) adjacent to the tailgate (3), a discharge auger (4) rotatably supported within the housing (5) and arranged to receive material which passes the tailgate (3) when the bed is tipped, auger drive means (9) to drive the auger and discharge material carried within the vehicle bed (2) to the side of the vehicle (1) as the bed is tipped and flow control means (10) capable of differentially exposing material held within the vehicle bed (2) to the discharge auger (4). The flow control means comprises a flow control gate (10) which is capable of being movedin a plane substantially perpendicular to the plane of the base of the vehicle bed (2) and tilted to form a tapered and adjustable opening which exposes material within the vehicle bed to the auger as the bed is tipped. The nature of an augeris to preferentially pick up material from one end remote from that at which material is discharged and so the flow control gate is tilted to expose less of the auger to the material at that end. The combination of varying the opening heightand degree of tilt of the flow control gate ensures material is discharged evenly and controllably across the width of the vehicle bed.

Abstract: A thermal and shock resistant data recorder assembly as an outer container (1) containing an inner container (2) which in turn houses one or more data recorder elements (3). The elements (3) which have a thin conformal coating thereon are encapsulated in an innermost cavity (4) of the inner container (2) in an Ester wax material which absorbs heat when changing from a solid to a liquid. An outermost cavity (8) surrounds the innermost cavity (4) in the container (2) and in turn contains a first insulating material which gives off water vapour when heated to absorb heat. Surrounding the inner container (2) in the outer container (1) is a second insulating material.  The Ester wax material is enabled to leak when liquid into the outer container and from thence, if necessary, to the exterior of the outer container.          This permits pressure equalisation. The first insulating material is provided with a fusible material plug which melts under heat and allows the vapour to escape to the exterior of the assembly.

Patent CA-2183502-A1 (CA)
Title: Gas detector
Inventor: TULIP JOHN
IPC: G01N21/39
Filed: 1996-08-16
Abstract: A gas detector of gas in a target zone has a transmitter of frequency modulated light and a receiver. In the receiver, a homodyne detection circuit mixes a detected signal with a reference signal at one of the modulation frequencies, where the reference signal has been derived from light that has passed through the target zone. The homodyne detection circuit includes a bandpass filter, amplifier, phase lock loop and phase shifter. Etalon fringes are reduced by moving them to high frequencies and filtering them out. Gas density is measured by comparison of the detected signal from the target zone with a signal from a gas reference cell. A method of detecting gas includes transmitting frequency modulated light through a target zone, receiving the light, and homodyne detection of the detected signal by mixing the detected signal with a reference signal at one of the modulation frequencies, where the reference signal has been derived from light that has passed through the target zone. Light from a laser transmitter propagates along several optical light guides from a laser transmitter to a laser receiver. The optical light guides form a guided light path traversing each of several target zones where unwanted gas may be present. An optical switch permits selection of one of the paths and hence one of the target zones for the detection of gas. A preferred light guide uses optical fibers with optical switches, or a combination of a splitter and a switch. A lens system provides for the collection of light from a transmitting fiber optic and receiving fiber optic. The gas detector is provided with means to eliminate phase sensitivity of the detector. Also, a gas detector for detecting a target gas in multiple target zones. A light collector receives light from the first scanning optical element that has returned from the multiple target zones and directs the light towards the receiver. A controller controls the position of the first scanning optical element and thereby controls which of the target zones is traversed by light from the laser transmitter.

Two of the plurality of TIR surfaces (138, 140) are located either side of the focal point of the aspheric illuminating lens. An aspheric imaging lens (142) having a split-axis aperture stop transfers the image rays to the image sensing device.
