Granted: 1994-02-08
Abstract: ABSTRACT OF THE DISCLOSURE          A reclosable bag having an open end with a side margin adjacent the open end, a metal segment in the side margin having ends extending beyond the opening and a sealing tape overlying the metal strip for encapsulation thereof.  Apparatus for manufacturing reclosable bags includes a continuous webbing of flexible bags joined end-to-end, a continuous roll of metal strip with an arrangement for forming the metal strip into discrete segments.  A roll of adhesively coated sealing tape and an arrangement for positioning the sealing tape over a metal strip segment while applying the sealing tape to one end of a flexible bag.  A method of forming the reclosable bags includes the steps of providing a serial succession of bags joined end-to-end, stretching a portion of each bag so as to be free of wrinkles, aligning a metal strip segment with the wrinkle-free portion of the bag and sealing the metal strip segment of the bag with a portion of sealing tape.

Title: Isobenzothiazolone chromogenic thiol indicators and their derivatives
Inventor: ALBARELLA JAMES P
IPC: G01N31/22
Filed: 1989-06-01
Granted: 1999-09-21
Abstract: The present invention involves a newly synthesized chromogenic thiol-indicating isobenzothiazolone derivative having the structure:   (see formula I) In this. structure at least one of R1 and R2 is preferably nitro, arylazo, substituted arylazo, benzylideneamino or substituted benzylideneamino.   When only one of R1 and R2 is so substituted, one of R1 and R2 may be hydrogen. The R3 substituent is preferably alkyl, carboxyalkyl, hydroxyalkyl, aminoalkyl, haloalkyl, aryl, carboxyaryl, hydroxyaryl, aminoaryl, heteroaryl, carboxyheteroaryl, hydroxyheteroaryl, aminoheteroaryl, hydroxy, alkoxy, or amino.    Preferred species of the isobenzothiazol-3-one derivative of the present invention are seen which comprise R1 as nitro and R2 as hydrogen. Other preferred species include derivatives where R2 is hydrogen and R1 is the the arylazo, phenylazo, the substituted arylazo, 4-hydroxyphenylazo, 4-nitro-2-methylphenylazo, 2-hydroxy-1-napthylazo, 2-hydroxy-5-methylphenylazo, 2-hydroxy-4-methyl-5-nitro-phenylazo, 4-hydroxy-1-napthylazo, 4-hydroxy-3-methyl-1-napthylazo, 4-hydroxy-5-aza-1-napthylazo, 2-amino-1-napthylazo, 1-hydroxy-2-napthylazo, 1-hydroxy-2-(N-dimethylaminopropylcarbamoyl)-4-naphthylazo, 1-hydroxy-4-methoxy-2-naphthylazo, 2-hydroxy-3-carboxy-1-naphthylazo, 1-hydroxy-3,6-disulfo-2-naphthylazo, 2,3-dihydroxy-1-naphthylazo, and 2-hydroxy-3,5-dimethyl-1-phenylazo. In one particular embodiment R1 is the substituted benzylideneamino, 2,4-dinitrobenzylideneamino and R2 is hydrogen.      Particularly preferred compounds of the present invention may have R3 which is alkyl, aryl, hydroxy, alkoxy, phenyl or amino. These, in turn, can be substituted with functional groups selected such that they provide the necessary reactivity and/or solubility properties. Some functional groups are chosen so that they will react with macromolecules, causing the indicator to be immobilized.      A central utility of the compounds of the present invention involves their use in the detection of thiols. Thus, the present invention comprises a process for measuring the presence or appearance of thiols, particularly in an aqueous system. This process comprises contacting said aqueous system with a chromogenic thiol-indicating isobenzothiazolone derivative as described herein.      Chromophoric changes due to thiol-mediated reduction of the isobenzothiazolone derivative then occur.      Such changes can be in a solution or on an indicator surface in contact or having been in contact with the aqueous system. The chromophoric changes, due to a bathochromic shift in characteristic light absorption upon reduction of isobenzothiazolone derivative, are proportional to the amount or rate of appearance of thiols in the aqueous system.

Title: Process for the selective growth of gaas
Inventor: MEIER HEINZ P
IPC: H01S5/227
Filed: 1989-06-02
Granted: 1993-03-02
Abstract: ABSTRACT            The process is particularly useful in the fabrication of GaAs quantum well (QW) laser diodes. Starting point is a ridge-patterned (100)-substrate (21), the crystal orien-tation of the sidewalls,  e.g.,  (411A)-oriented,  being different from that of the horizontal top. The sidewall facets thus have a lower Ga incorporation rate.            In  a molecular  beam epitaxy  (MBE)  system,  the  lower AlGaAs cladding layer (22) is first grown,  followed by the high-temperature growth of the active GaAs QW (23). Due  to  diffusion  and  desorption  processes,  the  GaAs thickness at the sidewalls is smaller than on the hor-izontal top of the ridge. During a short growth inter-rupt,  the  GaAs  completely  desorps  from  the  sidewall facets. With the subsequent growth of the upper cladding layer (24), the QW becomes laterally embedded in higher bandgap material providing for lateral electric confine-ment.

Abstract: A lock which is adapted to transduce the code from a key by electronic means is constructed to resemble the form and functionality of a conventional mechanical cylinder lock. A main casing 1 houses the bolt 3, a rotatable thrower or cam for retracting the bolt, an electromechanical release mechanism which normally blocks rotation of the thrower, and a processor to control the release mechanism in response to the detected key code. The electronic reading means are located in association with the keyway 26 of a rotatable barrel 25 in a cylinder unit 19 manufactured as a separate unit from the main casing 1. The thrower and barrel 25 have respective cooperating mechanical couplings 36/37 and the main casing 1 and cylinder unit 19 have respective cooperating electrical connectors 34/33. The lock is therefore assembled by attaching the cylinder unit 19 to the outside of the main casing 1, thus establishing a rotary driving connection from the barrel 25 to the thrower and establishing an electrical connection from the key reader to the processor.
