Title: Cysteine protease inhibitors containing heterocyclic leaving groups
Inventor: ZIMMERMAN MARY P
IPC: C07D405/12
Filed: 1994-12-07
Abstract: A class of cysteine protease inhibitors which inactivate a cysteine protease by covalently bonding to the protease and releasing a heterocyclic leaving group is presented.  The cysteine protease inhibitors of the present invention comprise a first portion which targets a desired cysteine protease and positions the inhibitor near the thiolate anion portion of the active site of the protease, and a second portion which covalently bonds to the cysteine protease and irreversibly deactivates that protease by providing a carbonyl or carbonyl-equivalent which is attacked by the thiolate anion of the active site of the cysteine protease to sequentially cleave a heterocyclic leaving group. The heterocyclic leaving group of the protease inhibitor is of the formula: - O - Het, where Het is a heterocycle having 4-7 atoms in the ring, with at least one of the heterocycle atoms being N, O or S.

Title: Flexible bag and method of making and attaching a tie
Inventor: RUTLEDGE GARY L
IPC: B31B50/18
Filed: 1995-01-11
Abstract: A plastic film bag (B) having a tie element (62') coated on its inner surface with an adhesive (358) between the dotted line (356) and its outer end (354). The adhesive is completely covered by a removable release strip (360). The inner end portion (62a') is permanently attached to the bag by means of a heat seal (362) or a permanent adhesive.

Title: Multi-layer bar code arrangement using wavelength separation
Inventor: CHRISTY ORRIN D
IPC: G06K19/06
Filed: 1995-12-06
Abstract: A substrate capable of receiving and retaining imaging is coded so as to maximize the amount of the scannable information that can be packed into an area, and/or to provide an effective security feature. A first machine readable identification code (12) (e g. bar code) is imaged on a predetermined area of the substrate (30), and is opaque to a first predetermined wavelength range of electromagnetic energy (e.g. the infrared region of light). An overlay (13, 27) is applied over and a least partially covering the first code. The overlay is transparent to the first wavelength range. and opaque to a second wavelength range (e-g-the visible spectrum of light). The overlay may be a security block (27) which substantially completely covers the first code, or may be a second bar code (13) (or additional codes) which is transparent to the second range. The codes may be read by multiple passes of different scanner heads (15, 16) by relative movement between the heads and the substrate, or by a scanner (23) in which first and second (or more) different scanner heads are mounted together so that two different wavelength range bar codes on the substrate may be read at the same time.

Abstract: Système d'émission d'un faisceau laser utilisé pour des traitements de surface et d'alignement. Le laser (500) produit une émission (502) selon un certain trajet à un niveau d'énergie convenant au traitement d'une surface. Un translateur optique (520) déplace le trajet du faisceau selon un trajet de faisceau résultant. Un ajusteur optique d'angle (310, 316, 320, 326) fait varier l'angle du trajet de faisceau résultant par rapport au trajet initial pour que le faisceau vienne frapper la surface à traiter. Un détecteur de mouvements (100) émet une énergie lumineuse (101-T) sur la surface et en reçoit de l'énergie lumineuse réfléchie (101-R) renvoyée par la surface par l'ajusteur optique d'angle. L'énergie emprunte, dans ledit ajusteur optique, un trajet parallèle à celui du faisceau décalé. Le détecteur de mouvements détecte les mouvements de la surface par rapport au trajet initial et produit des signaux de commande d'erreur représentatifs desdits mouvements. L'ajusteur optique d'angle modifie l'angle du trajet du faisceau résultant en réponse auxdits signaux d'erreur.

Patent CA-2190316-A1 (CA)
Inventor: LAKDAWALA NESS
IPC: F24F3/14
Filed: 1996-11-14
Abstract: A new method for defrosting a dehumidifier. The new method minimizes the formation of liquid "slugs" which can occur during normal defrosting and which can damage the compressor, and also makes the operation of the dehumidifier more efficient. In the new method, defrosting take place with the fan running to draw warm, room air over the condenser to warm the refrigerant passing through it in reverse, to thus minimize the formation of liquid "slugs". The warm air however is prevented by baffles from passing over the evaporator where it would undesirearably pick up moisture from the melting ice on the evaporator. An apparatus for carrying out the above method is also provided.

Title: Method of and Apparatus for Scrambling a Video Signal with Full Network Transmission and Recording Capability
Inventor: RYAN JOHN
IPC: H04N21/4408
Filed: 1995-07-27
Abstract: A video scrambling and descrambling system that produces color video that is difficult or annoying to watch by randomly switching the color components of a component or composite video. In the scrambling portion, component or composite video (12) is decoded (14) into a luminance component (18) and its two color components (20, 22). A random switching signal (34) is generated (16) to randomly switch the relationship of the color component signals (20, 22). The randomly switched color component signals (30, 36) may be encoded (38) together with the luminance signal (18) to produce a component or composite video signal (40) that is scrambled. The random switching signal (42) is transmitted as part of the encoded signal or through a separate transmission channel such as a control track or radial track portion of a recording medium. A descrambling portion first separates (92) the scrambled component or composite video signal (90) into a luminance component (96) and two scrambled color components (98, 100). The random switching s ignal (106) that has been transmitted to the descrambler along with the scrambled video signal (90) is used to restore the original relationship between the color component signals (98, 100). The luminance component (96) as well as the two descrambled color components (108, 110) are then encoded (114) to produce a component or composite video (112) with the relationship between the color components restored to their respective original positions in the video signal. The method may be used in various transmission and recording formats.
