Title: Use of platelet derived growth factor in ophthalmic wound healing
Inventor: STERN MICHAEL E
IPC: C07K14/49
Filed: 1993-02-24
Abstract: A method of accelerating corneal wound healing and/or improving the quality of wound healing in a mammal comprises: (1) providing an ophthalmically compatible solution of platelet-derived growth factor; and (2) applying the solution to the cornea of a mammal at the time of or subsequent to occurrence of a corneal wound in a quantity sufficient to accelerate clinically detectable healing, the healing being accelerated through proliferation of epithelial cells and/or keratocytes of the cornea stimulated by application of the platelet-derived growth factor to the cornea. The method also improves the quality of wound healing. The platelet-derived growth factor can be selected from the group consisting of the AA isoform, the AB isoform, the BB isoform, and mixtures thereof.  A preferable form of platelet-derived growth factor is a recombinantly-derived refolded B-chain homodimer of 119 amino acids, having the amino acid sequence of S-L-G-S-L-T-I-A-E-P-A-M-I-A-E-C-K-T-R-T-E-V-F-E-I-S-R-R-L-I-D-R-T-N-A-N-F-L-V_ -W-P-P-C-V-E-V-Q-R-C-S-G-C-C-N-N-R-N-V-Q-C-R-P-T-Q-V-Q-L-R-P-V-Q-V-R-K-I-E-I-V_ -R-K-K-P-I-F-K-K-A-T-V-T-L-E-D-H-L-A-C-K-C-E-T-V-A-A-A-R-P-V-T-R-S-P-G-G-S-Q-E_ -Q-R. The concentration of platelet-derived growth factor in the solution can be from about 10 µg/ml to about 1000 µg/ml, preferably from about 50 µg/ml to about 500 µg/ml, and most preferably about 100 µg/ml. The invention also comprises pharmaceutical compositions for application to the cornea of a mammal for accelerating corneal wound healing and/or improving the quality of wound healing and tablets for preparation of the pharmaceutical compositions.

Abstract: CROSS-SPRING-JOINT FOR SIDE-PIECES OF SPECTACLES                SUMMARY            The present invention relates to a new kind of joint, in particular for securing side pieces of spectacles to the frame of spectacles, which is capable of conferring to the bows an appropriate elasticity, both when they are braced over the temples and when they are opened or closed, so that they are not limited by any problems of size. The characteristic feature of the joint is that it has a forked part or forked spring (11 or 111), the ends (112, 114) of which have inner surfaces provided with teeth (122, 123, 124, 125) or grooves (16, 17) with slanting walls shaped so that they stand at right angles to each other and are concentrically arranged around a transverse joint pin (19, 119) linked to a second part inserted between both fork ends (112, 114). Said part is fixed to the frame (18, 118) of the spectacles and allows both parts to rotate, pressing apart the ends (12, 14 or 112, 114) of the fork, achieving the desired elasticity when the parts are rotated.

Title: Measuring and adjusting optical axis of a headlight
Inventor: MURATA NAGATOSHI
IPC: G01M11/06
Filed: 1994-12-14
Abstract: The alignment of the optical axis of a headlight HL is examined by projecting the light from the headlamp onto a translucent screen (2). A light shielding panel (5) and an imaging screen (7) are attached to the lower portion of screen (2). Light enters the device by pinhole (6) and is reflected from mirror (8) and imaged onto screen (7).      Camera (3) views both the illumination pattern on translucent screen (2) and the image of the light source on screen (7). The actual position of the headlight HL is located from the position of the source image on screen (7). A measuring area is then positioned on screen (2) and the headlamp is adjusted until a characterizing feature of the pattern on screen (2) lies within the measuring area.      The optical axis may also be corrected by adjusting the headlamp so that the image of the source on screen (7) becomes a normal shape.

Title: Metal to metal sealing wireline plug
Inventor: TURNER EDWIN CARROLL
IPC: E21B33/00
Filed: 1995-12-01
Abstract: The method and apparatus includes lowering a blanking plug assembly into the bore of an oilfield tubular member and inserting a sealing assembly on the blanking plug assembly into the seal bore of the tubular member without sealingly engaging the seal bore.  A support shoulder on the blanking plug assembly lands on the landing shoulder of the oilfield tubular member. Wireline jars jar down on the lock sleeve of the blanking plug assembly to shift dog members radially outward into latching grooves in the oilfield tubular member.  The lock sleeve then locks the dog members into the latching grooves. The wireline jars then jar up on a plug of the blanking plug assembly to move the plug upwardly to an upper position within the blanking plug assembly. The sealing assembly is prevented from moving upward and a tapered surface on the plug is driven through the sealing assembly thereby radially energizing the sealing assembly into sealing engagement with the outer tubular member. As the plug moves upwardly, latch members disposed on the blanking plug assembly are received by grooves in the plug to maintain the plug in its upper position. The method provides definitive indications as to whether the dog members are locked into place, whether the sealing assembly is in metal-to-metal engagement with the outer tubular member, and whether the plug is latched in its upper position.

Title: Freehand image scanning device and method
Inventor: ALLEN ROSS R
IPC: H04N1/107
Filed: 1996-01-10
Abstract: A scanning device (10) and method of forming a scanned electronic image (54) include an imaging sensor (22) and at least one navigation sensor (24 and 26).  In the preferred embodiment, the imaging sensor is a linear array of sensor elements, with a two-dimensional navigation sensor array at each end.  The scanning device has three degrees of freedom, since position information from the navigation sensors allows manipulation of an image signal from the imaging sensor to reduce distortion artifacts caused by curvilinear scanning.  Acceptable sources of the position information include printed matter and contrast variations dictated by variations in the inherent structure-related properties (64) of the medium (14) on which the scanned image is formed. Illumination for optimal operation of the navigation system may be introduced at a grazing angle (30) in some applications or in the normal to a plane of the original in other applications, but this is not essential.

Title: Circuit and method for battery charge control
Inventor: STOCKSTAD TROY LYNN
IPC: H01M10/44
Filed: 1996-02-16
Abstract: A battery charge control circuit (10) senses the charge condition of cells in a battery pack (12, 14, 16, 18) using measurement circuit (51). Upon detection of a single under-voltage cell, the charge control circuit is placed in a sleep mode. Pack sense circuit (240) senses when the battery pack is placed in a charger. If circuit (10) was in a sleep mode, it is awakened. If any cell is measured over-voltage, the status is checked versus the other cells. If all the cells are over-voltage, the battery is considered balanced. If one or more cells are not over-voltage, control circuit (32) activates a discharge transistor (212, 214, 216, 218), discharging the cell within a hysteresis voltage below the over-voltage limit. Charge balancing of cells is continued until the cells are within a programmable hysteresis voltage of each other.
