Patent CA-2011239-C (CA)
Title: Construction kit for horizontally and vertically sliding window assemblies
Inventor: DALLAIRE RAYMOND
IPC: E06B3/44
Filed: 1990-03-01
Granted: 2000-10-17
Abstract: A construction kit for horizontally and vertically sliding window assemblies is provided wherein a single set of extruded profiles are used to construct either type of window. Each window has a main frame including a sill, a header and a pair of jambs which are constructed from a single hollow multi-chambered main frame extrusion. Each window also includes at least two sashes which are likewise framed by a single multi-chambered sash extrusion profile. Other features of the construction kit include snap in glazing profiles which permit the rapid and economical glazing of window panes, snap in members for supporting weather stripping and guiding window sashes to provide extra versatility in the placement of guide rails and weather stripping. A unique system for weather stripping at the meeting rails is also provided whereby a slot for holding weather stripping is provided on the rear surface of the meeting rails so that the weather stripping can be wrapped around the end of the meeting rail and secured by frictional engagement between the rear surface of the rail and the window sash. This not only provides a much faster system for weather stripping the meeting rails but also provides a much more effective barrier against the intrusion of air in the area between the ends of the meeting rails and the window sashes. An additional feature of the construction kit is the two tiered main frame extrusion which provides an extra surface along the outer edges of the window to permit installation of an additional weather stripping, thus yielding a window with superior wind resistance.

Title: Compressor housing having a structure for preventing slippage of vibroisolating members
Inventor: TAKAHASHI HAREO
IPC: B60H1/32
Filed: 1990-03-07
Granted: 1996-10-08
Abstract: An automotive refrigerant compressor according to the present invention comprises a compressor housing that includes at least one bracket. The bracket has a hole through which a fastening member, such as a bolt for example, penetrates. A vibroisolating member is provided that includes a cylindrical portion and an annular flange portion radially extending from one end of the cylindrical por-tion. The cylindrical portion is firmly inserted into the hole in the bracket, with the flange portion disposed at an outer surface of the bracket. The flange portion includes a pair of protrusions on oppos-ing sides of the flange portion. The protrusions are inwardly bent at the base thereof so as to fit along a side surface of the bracket when the cylindrical portion of the vibroisolating member is inserted into the hole. In accordance with this construction, the refrigerant com-pressor can be easily mounted within the engine compartment of a motor vehicle without having to be concerned with the conventional problem of slipping vibroisolating members. Furthermore, when a so-called vibroisolating steel member is used as the vibroisolating member of the present invention, separation of the vibroisolating member's rubber plates from the steel plates can be prevented with-out having to be concerned with the amount of torque used to tighten the fastening bolt.

Title: Automatic changeover manifold
Inventor: MARIC RADOVAN R
IPC: G05D16/06
Filed: 1990-09-26
Granted: 1994-03-29
Abstract: An automatic changeover manifold is described which permits an uninterrupted supply of fluid, for example, cryogenic  liquified  gas,  from  a  source  to  a  fluid delivery  conduit.    Liquid  flow  is  controlled  by solenoid-operated on-off valves which are switched from an open-condition to a closed-condition in response to a detected low pressure condition.   When flow ceases in one feed line, the solenoid-operated valve in the other feed line opens.   The electrical circuit prevents both solenoid-operated valves from being open at the same time,  provided an electric current is present in the circuit .

Granted: 2002-02-19
Abstract: A method and apparatus for mounting and tightening an open clamp about an object to be fastened in which a first jaw-like member causes the band end portion intended to constitute the inner bard portion to be placed about the object to be fastened, a second jaw-like member then causes the other band end portion of the clamp intended to constitute the outer band portion to be placed about the object to be fastened in such a manner that the outwardly extending hook or hooks in the inner band portion is or are adapted to engage with the corresponding aperture or apertures in the outer band portion. Two further jaw-like members each having pincer-like nose portions at the free ends are then actuated to engage with the outwardly extending leg portions of a plastically deformable ear in the clamping band to plastically deform the latter after the mechanical connection by engagement of the outwardly extending hook or hooks in the corresponding aperture or apertures is established, to tighten the clamp about the object to be fastened. A holding device thereby holds the clamp in position until the first and second jaw-like members have been actuated and assume the holding function to permit release of the clamp by the holding device. Operation of the machine is fully automatic by appropriate sequence controls of fluid-actuated piston and cylinder units.

Abstract: A fluid transfer structure for a transmission has a tube disposed in a central bore of a shaft.  The shaft and the tube cooperate to provide a feed passage, central of the tube, and a substantially annular lube passage formed between the tube and the central bore. The tube and shaft have cooperating structures that provide proper alignment of the tube in the central bore.

Title: On-board catalytic converter efficiency monitoring
Inventor: HAMBURG DOUGLAS R
IPC: F02D41/14
Filed: 1993-08-20
Granted: 1995-10-03
Abstract: Apparatus,  method  and  system  are  provided  for monitoring catalytic converter efficiency in treating exhaust gas from an internal combustion engine.   The air/fuel ratio fed to the engine is perturbed on a cylinder-to-cylinder basis above and below a mean or average air/fuel ratio.   The signal from an exhaust gas exposed to the exhaust gas sensor downstream of the converter for the perturbation interval is compared to  the  signal  for a  non-perturbation  interval.   A signal  is  generated  when  the  comparison  indicates catalytic converter   efficiency   below   a  minimum acceptable level.   The comparison may be carried out by comparing the difference in the mean value of the EGO sensor output signal for the perturbation and non-perturbation  intervals  to  a  preselected  and  stored reference value corresponding to the minimum acceptable efficiency.  The efficiency monitoring test system may be incorporated into fuel control means for controlling air/fuel ratio during normal engine operation.
