Patent CA-2068577-A1 (CA)
Inventor: JAMES DAVID R
IPC: B60J9/02
Filed: 1992-05-13
Abstract: The invention relates to an emergency exit window for vehicles such as school buses.  Spring biased latches are carried by the upper part of a window pane.  The spring biased latches have bolts which engage stops at various locations on opposite sides of the window frame surrounding the window.  The latches may be normally operated individually by hand to raise and lower the window between a ventilating position (including half-open and other partially open positions),  and a fully closed position.   The window is equipped with an emergency handle which may be used to pull the latches towards each other, and thereby enable the window to assume a fully open position.  In the fully open position, inversion stops prevent the window from inadvertently closing in the event that the vehicle is overturned.  The latches are housed in a latch cover which has latch openings.  The latch openings are sized so that they prevent manual use of the latches to cause the window to be fully opened.  Therefore, only the emergency handle may be used to move the window to the fully open emergency position.

Title: Information reading and recording using a scanning tunnel microscope
Inventor: YAMANO AKIHIDO
IPC: G01B7/34
Filed: 1992-05-13
Abstract: There is disclosed an information recording/reproducing apparatus utilizing a probe electrode and a recording medium, based on the principle of scanning tunnel microscope. When a track groove on the recording medium is detected, the distance control between the probe electrode and the recording medium is suspended. Consequently, the tip of the probe electrode does not enter the track groove, and is prevented from collision with the recording medium. The scanning speed of the probe electrode can, therefore, be increased without the danger of such collision. <IMAGE>

Abstract: TITLE               EXPANDABLE MULTI-PLY OBLIQUELY ORIENTED        HONEYCOMB FILTER MEDIA                     APPLICANT  HONEYCOMB CONSTRUCTION SERVICES LTD.                     INVENTORS          Victor Vernon SPENCER (deceased) c/o his executrix Mary Spencer - and -Leonid Andreevich BAGRIN                       ABSTRACT    A multi-ply expandable filter media formed of obliquely oriented honeycomb organized into a ply or run having expandable honeycomb cells with one run oriented at, preferably an acute angle, of 30° to 60° relative to the cells of an adjacent run.  Preferably, the respective plys or runs are arranged in relative parallel planes defining a planar space therebetween.  There is provided means for collapsing the filter media into a closed compressed, transportable state, and when ready for use as a filter media, to allow the same to be expanded and pulled open and to be constrained in an preselected, open, expanded position so that the cross sectional area of each cell is thereby substantially increased. In this manner, the juxtaposed, open plys allow directional change for airflow flowing through the filter media, encouraging deposits of air-borne material to become attached to the wall surfaces of the family of cells of each run or ply. To enhance adhesion, an adhesive may be sprayed over the cell walls.

Patent CA-2085199-A1 (CA)
Inventor: DAY RICHARD M
IPC: B60L3/02
Filed: 1992-12-11
Abstract: The present invention features an improved technique for slowing and stopping a vehicle having an electric service motor, a mechanical parking brake, and a deadman's switch for engaging the mechanical brake.  The method of the invention improves the efficiency of the braking procedure.          The braking method initially determines if the deadman's switch is engaged.  If it is, then the electric service motor is plugged at a predetermined minimum plug rate until the vehicle slows to a specified velocity.  When the specified velocity is reached, the plugging operation is terminated.  The mechanical brake is then engaged to slow the vehicle to a halt.  When the vehicle comes to a halt, the parking brake remains engaged.  The invention also improves safety by increasing the controlled rate of plugging to a maximum value in the event that the deadman's switch is off.  Actual braking performance by plugging is compared with that of accepted rates of deceleration or plugging effort shown by armature current to verify operation of the service braking system.  In the event of inadequate service braking, such braking is terminated and the mechanical brake is applied.

Abstract: An apparatus and method for determining the amount of nitrogen in an object. A support means is provided for supporting the object, and at least one gamma ray beam is disposed on one side of the support for producing a beam of about 9.2 MeV gamma rays and in sufficient intensity to cause measurable resonant absorption by 14N in the nitrogenous compounds. A directing device is disposed between the gamma ray beam and the support for directing the gamma ray beam to the support at a predetermined angle, such that the gamma ray beam forms a path which encounters at least a portion of the object when disposed on the support. An array of gamma ray detectors are disposed on an opposite side of the support for detecting gamma rays of about 9.2 MeV transmitted through the object at both resonant and non-resonant angles. A computation device computes the difference in the amount of transmitted gamma rays detected by the detectors at the resonant angles and non-resonant angles, and the difference is related to the amount of nitrogenous compounds in the object.
