Patent CA-2033923-A1 (CA)
Title: Safety latch for a tire carrier
Inventor: GREAVES JEFFREY
IPC: B62D43/04
Filed: 1991-01-10
Abstract: This  invention provides a safety mechanism for a winch assembly when storing a load,  in a raised or stored position,  such as a tire under a vehicle,  or a boat on a trailer.  The invention finds particular application to a spare tire, but those skilled in the art will appreciate the broader benefits of such a structure when used with a winch assembly for other uses such as a boat winch for a trailer or any analogous use wherein it is desirable to ensure the confining of a load in the raised or stored position.

Title: Check-relief valve for a hydraulic circuit
Inventor: FOX THOMAS R
IPC: F16K15/14
Filed: 1991-01-30
Abstract: CHECK-RELIEF VALVE FOR A HYDRAULIC CIRCUIT            ABSTRACT OF THE DISCLOSURE             A  check-relief  valve  for  use  in  a  hydraulic circuit  comprises  a  channel  through  a  valve  body  which  is divided by a central annular restriction into two portions.  On each  side  of  the restrictor  is  provided a valve  seat which cooperates  with  a  spherical  ball  to  close  off  flow  in  a direction  toward  the  restriction.   At the outer end of each portion of  the  channel  is provided  a perforated plate which prevents the ball from restricting flow when the ball is forced against the plate.  Either the ball or the restrictor is formed of a resilient deformable material which can be deformed when the pressure in the fluid exceeds a predetermined maximum in which case  the ball is forced through the restriction to the opposite portion of the channel.   The check valve is used in a system of a  swather  for moving one of the draper assemblies longitudinally of the frame of the swather and simultaneously reversing the direction of rotation of the drive to the draper.      A check valve restricts the fluid flow to the drive motor for the  rotation  of  the  draper  so  that  all  of  the  fluid  is available to move the draper and its support longitudinally of the  frame  until  the draper  reaches  end stops whereupon  the check valve releases by the deformation of the valve member to allow fluid to continue to flow through the drive motor to the draper rotation.

Title: Belt conveyor weighbridge
Inventor: PORCARI VINCENZO
IPC: G01G11/04
Filed: 1991-04-17
Abstract: BELT CONVEYOR WEIGHBRIDGE ABSTRACT OF THE DISCLOSURE   A weighbridge for a conveyor belt assembly for measuring the weight of a section of conveyor belt carrying a load of material to be transported along the conveyor belt assembly is disclosed. The conveyor belt assembly has frame members positioned longitudinally along side the conveyor belt and engages the underside of the conveyor belt to support it. The weighbridge comprises one of these crossmembers, with said member being mounted for generally vertical movement relative to the adjacent frame member and thus constituting a weighbridge crossmember. The weighbridge further comprises a load sensing assembly mounted on the adjacent frame member for supporting the weighbridge crossmember. A bracket member selectively mounts the load assembly on the adjacent frame member moveable between first and second positions. In the first position, the load assembly and weighbridge crossmember are free to move longitudinally and transversely with respect to the frame member within a limited range of movement. In the second position, the load assembly is affixedly secured on the adjacent frame member against movement whereby on installation and adjustment of the weighbridge the mounting means is free to move so as to relieve longitudinal and transverse forces otherwise induced in the weighbridge and prior to use the load sensing assembly is mounted in condition free of such induced forces.

Patent CA-2041678-A1 (CA)
Inventor: MARZ DANIEL
IPC: H03D3/24
Filed: 1991-05-02
Abstract: An on channel frequency agile phase lock loop ("PLL") demodulator  is  provided  using  a  precise  and  stable oscillator, such as a voltage controlled crystal oscillator ("VCXO")  having  its  output  frequency variable  over  a limited range.  The output of the oscillator is multiplied by a multiplication factor to produce a mixing frequency.          The multiplication factor scales the limited range of the oscillator to produce a proportionate mixing frequency deviation.  A frequency synthesizer is used to enable the demodulator to detect signals on different channels.   In one embodiment, the output of the frequency synthesizer is mixed with the scaled oscillator output to provide a mixing frequency having a fixed deviation for all channels.  The demodulator can be used for detecting data transmitted over a cable television network.

Abstract: A method and apparatus is provided to retain elements (16) of the spine and/or pelvis in a desired spatial relationship. A plurality of fasteners (20) are connected with a plurality of the elements. A longitudinal member (26) is connected with the fasteners by a plurality of connector members (32). The longitudinal member and fasteners are movable relative to each other to adjust the distance between the longitudinal member and fasteners to thereby obtain the desired spatial relationship between the longitudinal member and elements to which the fasteners are connected. Once the longitudinal member and fasteners have been positioned in the desired spatial relationship, clamps (44, 50) are engaged to hold the longitudinal member, fasteners and connector members against relative movement. To provide for the adjustability of the longitudinal member relative to the fasteners, oblong openings (38) are formed in the connector members. In one specific method of adjusting the position of the longitudinal member relative to the fasteners, the longitudinal member is rotated about an axis which extends through a portion of the longitudinal member. <IMAGE>
