Abstract: ABSTRACT      A graft is used to supply blood to one or more coronary artery branches.  The graft is also usable as a peripheral revascularization and inter position pros-thesis to supply blood to desired blood vessels.  The graft has an elongated U-shaped tubular body provid-ing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver.  One or more openings in the body allow blood to flow into the coronary artery branches.  The flow and pressure of the blood in the passage is controlled by a restric-tion providing a restricted passage located remote from the inlet end of the tubular body.  In one embodiment, the restriction is reinforced with a sleeve to main-tain a desired cross sectional area and length of the restricted passage.  The pressure differential between the blood supply and blood receiver maintains continu-ous and adequate blood flow at a desired pressure in the continuous passage and provides a continual supply of blood for the coronary artery branches.

Abstract: METHOD AND APPARATUS FOR OPHTHALMOLOGICAL SURGERY     ABSTRACT OF THE DISCLOSURE     The invention contemplates use of a scanning laser characterized by ultraviolet radiation to achieve controlled ablative photodecomposition of one or more selected regions of a cornea.  Irradiated flux density and exposure time are so controlled as to achieve desired depth of the ablation, which is a local sculpturing step, and the scanning action is coordinated to achieve desired ultimate surface change in the cornea.  The scanning may be so controlled as to change the front surface of the cornea from a greater to a lesser spherical curvature, or from a lesser to a greater spherical curvature, thus effecting reduction in a myopic or in a hyperopic condition, without resort to a contact or other corrective auxiliary lens technique, in that the cornea becomes the corrective lens.  The scanning may also be so controlled as to reduce astigma-tism and to perform the precise incisions of a radial keratotomy.  Still further, the scanning may be so con-trolled as to excise corneal tissue uniformly over a precisely controlled area of the cornea for precision accommodation of a corneal transplant.

Abstract: ABSTRACT           A memory refresh circuit controls the refreshing of dynamic RAM included in a system wherein a control store outputs micro-code instructions to control the system opera-tion in response to sequences specified by a sequence and in-terrupt logic circuit (SIL).  A counter transmits certain counts  of system machine cycles to an array logic device.        In response to one count, the array logic device generates a memory refresh request signal which is applied to a RAM address logic circuit (RAL).  The RAL monitors the micro-code instruction output at each machine cycle to determine whether the instruction will access the dynamic RAM during that machine cycle --if not, the RAL generates a signal to initiate a memory refresh operation, which operation requires two machine cycles to complete.  The array logic device also monitors the micro-code instructions to determine if and when a refresh operation was initiated --if yes,  it deter-mines whether the instruction in the following machine cycle needs to access the dynamic RAM.  If it does, the array logic device generates a freeze clock signal which causes the SIL to freeze the execution of the instruction until the refresh is complete, i.e. this refresh will be partially transparent.          Alternatively, if no refresh has been initiated after a specified number of machine cycles, the array logic device generates an interrupt signal.  In response to this inter-rupt, the SIL causes the control store to execute a pair of NOP instructions to cause an uninterrupted refresh operation.

Abstract: Abstract of the Disclosure An apparatus for transferring a relatively flat object from a first station (10) to a second station (60) includes a support (11) for the object at the first station, a substantially closed housing, and a piston disposed therein for sliding movement from a normal position to an activated position.  An actuator (112) extends through the housing and is integrally formed with the piston for sliding movement thereby.  Compressed air is selectively directed into the housing for movement of the piston to the activated position, whereby the actuator (112) strikes a blow edgewise of the object for propelling it toward the second station along a predetermined path (116).  A pair of fingers (130) disposed at the second station define therebetween a portion of the path along which an incoming object enters the second station.  Each finger includes a path wall having an end surface extending generally inwardly from the finger for blocking the object path for halting object movement.  A spring pawl extending partially into the path from each finger prevents rebounding of the object from the end surfaces.

Abstract: EXTREME PRESSURE ADDITIVE FOR USE IN METAL LUBRICATION         ABSTRACT     It is known to use chlorinated paraffins as an extreme pressure lubricant additive in lubricating metals.  Such additives are highly corrosive, however, and for that rea-son are not suitable for a number of uses, such as in the lubrication of internal combustion engines.  The present invention overcomes the corrosive problems of the previous chlorinated paraffin additives.  The present invention in-volves the mixing of a major amount of chlorinated paraf-fins with a minor amount of an alkaline earth metal sulfo-nate, such as calcium sulfonate, and preferably a base mi-neral oil.  The resulting additive can be added to standard motor oil to improve its extreme pressure performance in internal combustion engines.

Abstract: Abstract The invention comprises a method for the determination of the volumetric flow rate of multi-phase fluid flows, for example, of the flow rate of an oil/water mixture in a conduit.  A known amount of radioisotopic tracer is injected into at least one of the phases and the concentration of the tracer in the flow is determined at a downstream sampling station, thereby enabling the flow rate of the multi-phase flow to be determined.  The tracer(s) used should be soluble in only one phase of the fluid flow with the proviso that where a plurality of tracers is used, no two or more tracers are soluble in the same phase.
