Abstract: LIFT ASSEMBLY INCLUDING A REACTION SWITCH             Abstract Of The Disclosure A lift system for a transit vehicle includes a stationary main frame secured within a door recess of the vehicle and a side frame that is movable relative to the main frame.  An articulated platform including steps pivotally secured to the side frame and scissor linkage pivotally and slideably connected to the main frame is also included.  The lift system also includes a reaction switch coupled to the main frame to sense torque imparted to the main frame upon engagement of the platform with an obstacle such as a curb or the ground. If sufficient torque is created due to contact of the platform with an obstruction, the reaction switch is actuated to terminate further downward movement of the platform thereby preventing destruction of the system.

Abstract: ABSTRACT     A cold applied joint sealant usable for both portland cement and asphaltic concrete pavements, which comprises an asphalt/urethane formulation resulting from the mixture of a liquid butadiene polymer, containing predominantly primary terminal hydroxyl groups, with a urethane reactant of di- or polyisocyanate. The sealant has low urethane content and cures to provide a low modulus, high penetration, with 85%-95% resilience and zero flow. An initial set time of less than about 120 minutes is achieved, which permits vehicular traffic to be accommodated thereover soon after application.

Abstract: ABSTRACT     The invention relates to the treatment of brine, and, more par-ticularly, to the treatment of the brine elutriate withdrawn after evaporation of the brine at an elevated temperature to separate some of the sodium chloride thereon.  The crude brine normally contains sodium sulphate and potassium chloride, sometimes to relatively high levels, and the invention is directed primarily at the separation out of these salts.  To achieve this, the brine elutriate is cooled in a chamber and a NaC1-/KC1-/Na2SO4- salt mixture is separated off by crystallization.  The remaining parent solution can be returned to the evaporation stage, without disturbing the equalized balance of the secondary salts in the brine to be processed.  The NaC1 present in the salt mixture can be recovered by deposition with refrigerated water and separation of the Na2SO4.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a fertilizing tool and holder therefor.  The holder interconnects the fertiliz-ing tool with a shank of a cultivator.  The holder has a base portion provided with at least one aperture through which a bolt passes  to releasably secure the holder  to  the  shank.          The holder is further provided with a pair of spaced apart wall portions, upstanding from the base portion, defining a tool receiving channel with a forward opening.  The wall por-tions include aligned apertures and have a rigid transverse member extending therebetween to reinforce the wall portions.          The wall portions are adapted to matingly receive the tool in the channel whereby an adjacent end of  the tool abuttingly engages the transverse member and the base portion.  A second nut and bolt or a roll pin passes through the aligned aper-tures and an aperture in the adjacent end of the tool to re-leasably secure the tool to the holding device.  At least one of the wall portions includes shielding protrusions adjacent its aperture to protect the nut.  The use of this holding de-vice  permits  for  the  tool  to  be  readily  replaced.  The fertilizing tool comprises an elongated blade having a for-ward facing,  substantially flat nosed end portion which  is adapted to cut into and shear earth below surface soil.  The blade is further provided with a leading cutting edge extend-ing above the flat nosed end portion which cutting edge is adapted to cut through the earth.  A channel is cast in the blade for delivering  fertilizer behind  the  flat nosed  end portion.   This  novel fertilizing  tool  delivers  fertilizer below the seed line with minimal tillage.

Abstract: ABSTRACT OF DISCLOSURE           Method and apparatus for heat shrinking projecting edges of heat shrinkable (but unshrunken) film onto articles such as cylindrical containers.  The film is tightly wrapped around the bodies of the articles and the overlapping ends are held together by glue.  The projecting edges of the articles are then heat shrunk onto the shoulders and/or curved lower ends of the bodies as the containers are transported and are caused to spin while being transported.          In so doing the hot air is blown in a direction such that it does not blow directly onto the glue at the side seams.         This may be accomplished by using a circular, turret type transport and by having blowers which blow hot air obliquely, rather than radially at the articles.  Where the articles are closely packed, each article acts to shield the next article when its side seam is parallel to the flow of hot air.

Abstract: FIBER OPTIC SWITCHABLE COUPLER   Abstract of the Disclosure A pair of optical couplers are arranged in series with a pair of outputs from the first optical coupler supplying the pair of  inputs  to  the second optical  coupler.   At least  one  of  the optical  fibers  between  the first and second couplers  is  arranged  to have a variable  length, said variation being at least one-half the wavelength of the light signal utilized within the system.  When light is supplied to one input of the first coupler, this light can be switched selectively to either of the outputs of the second coupler by varying the length of one of the optical fibers between the coupler.  Thus, a light signal supplied to either of the inputs of the first coupler can be  selectively output  at  either of  the outputs of the second coupler of can be made to alternate between these outputs in accordance with the length of the intervening optical fiber.

Abstract: ABSTRACT            A digital data processor is provided to  multiply data elements by coefficients.  It includes a systolic array of cells consisting of nearest neighbour connected gated full adders.  The cells multiply data bits received from laterally adjacent cells and subsequently pass them on.  The product is added to a cumulative sum bit from a cell above and to a carry bit recirculated from an earlier compu-tation.  The output is passed to a cell below, and a new carry bit is recirculated for addition  in a subsequent computation.  Data and coefficients are input in counterflow to opposite sides of the array. An adder tree accumulates non-simultaneously computed contributions to individual output terms.  The tree incorporates a delay and switches arranged to implement or bypass the delay according to earlier or later computation of a contribution.  By virtue of this accumulation, the processor provides reduced cell redundancy compared to the prior art.

Abstract: LASER TRANSMITTER Abstract of the Disclosure In a fiber optic laser controller for use in digital transmission a digital data stream and a DC bias are applied to the laser.  During a monitoring period, the DC bias is stepped from a zero to a peak current.  At a first threshold current, lasing occurs in response to digital '1' modulating current but not in response to digital '0' modulating current.  At a second higher threshold current lasing occurs in response to both digital '1' and '0'.  The threshold currents are identifiable as peaks in the second derivative d2L/dI2 where L is the light output for an applied bias current I.  A feedback circuit including a photodiode, D/A and A/D converters and a microprocessor controller are used to maintain the bias current at the second threshold current in spite of changes in the laser characteristics caused by device aging or temperature change.                         - i -
