Patent number: 4710195Abstract: A posterior chamber intraocular lens is usable as an implant in patients having both cataracts and glaucoma. The lens includes an optic portion which is capable of performing the focusing function of a human lens. Two haptics are connected to the optic. At least one of the haptic includes a blocking segment. The blocking segment has a length and width sufficient to prevent tissue posterior to a trabeculectomy fistula from occluding the fistula. The blocking segment thus creates a barrier to prevent the posterior chamber and other eye structures from interferring with proper drainage of aqueous humor from an eye.Type: GrantFiled: April 18, 1986Date of Patent: December 1, 1987Inventor: Vincent J.

Patent number: 4708640Abstract: The present invention relates to a method and apparatus for preparing a feed mixture, made of several batch components, at one stage in order to feed it into a smelting furnace. The preparation of the batch may include the preheating and drying of the material, the removal of crystal waters and evaporable substances as well as the conduction of the batch into the smelting furnace. According to the invention, a hot inert gas is conducted through a downwards settling batch so that the gas is mixed into the batch as well as possible, but even partial fluidization is prevented. The apparatus of the invention comprises a pretreatment silo (6) which is uniform at the upper part but is divided into several sub-silos (7) at the lower part. At the lower part of the sub-silos there are connected ducts (8) wherealong the batch flows into the smelting furnace (9) located below the pretreatment silo (6).Type: GrantFiled: December 22, 1986Date of Patent: November 24, 1987Assignee: Outokumpu OyInventors: Matti E.

Patent number: 4703476Abstract: An audio program is encoded with a subaudible binary code. A first value bit (mark) is a first frequency signal and a second value bit (space) is a second frequency signal. The coded message includes an initialization period constituted by a signal having the mark frequency. In decoding, the mark and space signals are detected through first and second band pass filters specific to the mark and space signal frequencies. The mark and space frequencies are sufficiently different to permit separate filtering. The time duration for each bit of the code is substantial. The decoder through a phase locked loop and integrator reads the bit on the basis of the average value of the bit over the duration of the bit. A synchronization signal provides for synchronous reading of the code. This signal that initiates the decoding operation is generated only in response to the coincident detection of the initialization signal, the notch and a mark response at the phase locked loop.Type: GrantFiled: November 6, 1986Date of Patent: October 27, 1987Assignees: Audicom Corporation, Bidco Inc.Inventor: Jonathan M. Howard

Patent number: 4699536Abstract: A pen and penholder combination includes a pen portion. An elongated flexible tether attaches on one end to the pen and on another end to a stop. A disk with a hole formed therein is slidingly received on the tether. The penholder is permanently securable to a writing surface. The penholder has a penholder surface with an upper and lower face. A disk securing slot is formed in the penholder surface. The slot is shaped and dimensioned to receive the stop therethrough and to receive the disk therethrough when the disk is oriented substantially perpendicular to the penholder surface. After the disk is passed through the slot and when it is not oriented substantially perpendicular to the penholder surface it abutts against the bottom face of the surface and cannot be passed through the slot.Type: GrantFiled: May 29, 1986Date of Patent: October 13, 1987Inventor: James Berman

Patent number: 4696046Abstract: A set of Search identification points derived from an optical scan of a finger are compared against File identification points for the same finger. A multiple comparator divides the finger image into multiple segments. The Search and File points from each segment are compared separately. A difference table (D.T.) provides a proximity value Q for each search point. The D.T. is purged of all entries representing multiple Search points. The purge keeps those entries having the highest Q value. The purged D.T. with recalculated Q values is the basis for correcting the position of each Search point on the image plane to compensate for shift in finger position and for the variable distortion and changes that come about in a finger over time and upon successive applications of the finger to input scan. The corrected Search points are compared against the File points to establish a new D.T. A proximity value Q for each entry on this D.T. is calculated and a proximity value Q for the entire table is calculated.Type: GrantFiled: March 27, 1986Date of Patent: September 22, 1987Assignee: Fingermatrix, Inc.Inventor: Michael Schiller
