Title: Curb cutting system
Inventor: BLACKHURST MICHAEL
IPC: B28D1/04
Filed: 1991-06-21
Abstract: ABSTRACT OF THE DISCLOSURE      A fully powered, one man curb cutting system is trailer mounted, for towing behind a vehicle to its location of use.       A motorized and steerable fifth wheel is deployed from a retracted to an extended position,  to raise  the trailer tongue clear of the hitch, and to propel and steer the trailer into  a  desired  position  adjacent  a  curb  to be  sawed. Referring to the vehicle left side when viewed from the rear, adjacent a working curb, as the "nearside", a pair of nearside jacks, carried on extensible arms pivoted to the trailer may be deployed to desired locations adjacent the curb to be sawn, in supporting relation with the saw.   The trail wheels may then be partially retracted in order to transfer some of the trailer weight onto the nearside jacks.       Adjustment to the extent of retraction of the trailer wheels permits orientation of the cutting plane of the power driven saw to a desired angle,  laterally,  whereat a set of off-side jacks are extended downwardly in supporting relation with the trailer off-side, and the wheels then retracted clear of  the ground.   Adjustment between  the nearside jacks can correct the cutting plane, longitudinally.  The saw is driven directly from a motor carried inboard  on a carriage mounted for longitudinal travel along a track on the chassis frame of the trailer.  The motor also powers a hydraulic pump, by means of which the fifth wheel system is operated in both its load transfer and trailer driving modes.  The pump also serves to to  energize  the  deployment  of  the  near-side  jacks,  the retraction of the four trailer main wheels, the loading of the off-side  jacks  in  trailer  supporting  relation,  and the powering of  the  carriage  along  the  chassis  frame  and the vertical positioning and lateral feed of the saw.

Title: Optical fiber connector having enhanced provisions for interconnection and for prevention of optical and mechanical disconnection
Inventor: ANDERSON JERRY M
IPC: G02B6/38
Filed: 1992-05-13
Abstract: An optical fiber connector which is assembled to a coupling housing by causing only relative linear motion between the connector and the housing and which also includes facilities for preventing optical disconnection from anotherconnector having a portion disposed in the housing includes a cap having two diametrically opposed slots each having an enlarged portion. A barrel is retained within the cap and has mounted thereto a ferrule in which is terminated an end portion of an optical fiber which is to be connected to another optical fiber. The connector is moved to cause the ferrule to enter a sleeve of a housing of a coupling and to cause locking pins of the housing to enter and to be moved along the slots of the cap until each pin is received in an enlarged portion of a slot. A cap extender is connected to an end of the cap and includes an annular detent. A shell which is disposed about and is slidably movable on the cap is moved to cause theannular detent projecting radially from the cap extender to become locked to latching means formed on an inner wall of the shell to lock the shell to the cap and prevent mechanical disconnection of the connector form the coupling mounted in apanel. An annular shoulder on the cap extender limits the travel of the ferrule to prevent optical decoupling from another ferrule in the coupling housing when tensile forces are applied to a cable the optical fiber of which is terminated by the ferrule.
