Title: Finger profile identification system
Inventor: COLBERT CHARLES
IPC: G07C9/00
Filed: 1990-04-11
Abstract: A method of and apparatus for verifying the identity of an individual is based on the profile of a hand print. A set of reference data is created by viewing (9, 10) an individual's hand and determining the location of the edges of each finger separately to generate a set of finger profiles, establishing a central axis for each finger profile by reference to the edges thereof, rotating the central axis of each finger profile until it is normal to a reference line, determining the width of each finger profile at predetermined locations parallel to said reference line, and recording said finger profile information in a memory such as an ID card.  Thereafter, a candidate's finger profile can then be compared (6) with the reference profile obtained by reader/recorder (7) by comparing the width of each finger profile at predetermined locations, determining whether the correspondence between finger widths at said predetermined locations meets a predetermined criteria, and then indicating acceptance or rejection of the candidate.

Abstract: -32-                   Case 150-5448 ABSTRACT   A process for the de-inking of printed waste paper containing paper that is printed with ink containing hydrophilic binder resins (for example as in the flexographic process) comprising a) pulping the waste paper at a pH of 4 to 7 in the presence of an ink collector chemical containing a hydrophobic portion and being cati-onic and water-soluble or sparingly water-soluble at a pH from 4 to 7;   b) applying to the resultant paper pulp a strong alkali to obtain a pH of 10-11; and c) separating the detached printing ink particles from the fibre suspension of the paper pulp by flotation.            A cationic surfactant is preferably added at the same time as the ink collector chemical.

Inventor: BEERENDS JOHN G
IPC: G10L19/06
Filed: 1991-10-10
Abstract: Frequency  components  are  calculated  from the  STP-filtered speech signal.  The amplitudes of these are combined in a manner such that the resultant values are associated  with   frequencies   which   are   situated equidistantly on a linear Bark scale. Said components are quantised, possibly after scaling. In the decoder, the components are again distributed over the frequency spectrum. In the coder, the fundamental regularity D is determined with an LTP technique, after which it is transmitted. In the decoder the phases of the reconstructed signal at the spacing D in the past are determined. These phases are combined with the amplitudes already present in the frequency spectrum, after which transformation back to the time domain takes place. Inverse STP filtering is then carried out.

Abstract: ABSTRACT             A fire escape chute for a home includes a housing secured to a building wall below a window having a first chamber for  a  compressed  air  tank having an  outlet with a normally closed release valve and a second storage chamber.  A yieldable chute support pan forms the bottom of the second chamber and is pivotally mounted upon the housing and retained in a horizontal position.  A hollow double wall open ended collapsible chute is stacked within  the  second  chamber upon  the  pan.   A normally closed  cover  is  pivotally  mounted  upon  the  housing  and supportably  retains  the  pan.   A  retracted  expansion  device within the second chamber is connected to  the cover and when manually  released  tilts  the  cover  to  an  upright  position retainingly engaged by a latch.   An air plenum on  the cover having a plurality of outlets is connected to the air release valve.   One end of  the chute encloses and is secured to  the plenum and communicates with its outlets. The cover outwardly opens upon release of  the expansion device,  triggers  the air supply to the plenum and chute,  the pan drops and the chute drops from its housing to instantly inflate.

Filed: 1991-12-30
Abstract: Abstract ST?D PLUG WELL EXTINGUISHING BO?EY WOGEY FLAME STARVER, AND BALLISTIC BLOWOUT CONTROL DELIVERY          In a tool for fighting oil well fires, it is known as a clam-ping device for securing a beveled tubular sleeve against the well casing manually or robotically in order that a drill or armour piercing stinger could be pressed or drill-ed through the tree flange, casing or tubing in one or more operations. Then a variety of different sealing materials by themselves or mixed with temperature con-verting agents could be injected directly through the well casing and into the production tubing thereby achiev-ing an instant shut in. This procedure then enables a second stage operation to pump a volume of fluid, gases or weight material to stabilize and control the well's hydrostatic to create the bottom hole control necessary for major work over proceedings. It also has the ability for quick solidification, killing the well so it can be cap-ped immediately. This unique characteristic includes any combination of oil or gas lines and watermains.

Abstract: PR?CIS Dans les modèles de supports à vélo actuellement sur le marché, plusieurs présentent des inconvénients non négligeables: - Instabilité des roues du vélo parce qu'elles ne sont pas fixées. - Certains supports avec appui sur la valise abîment la peinture de la voiture. - D'autres empêchent complètement l'accès à la valise de l'auto. - Le modèle de support à vélo installé sur le toit demande une force physique importante pour hisser le vélo sur le toit de la voiture. Il empêche aussi l'accès à un garage sous-terrain. - D'autres sont encombrants lors de l'entreposage. Contrairement à tous ces modèles, la présente invention s'installe très rapidement, est très légère tout en étant fort solide et permet une stabilité accrue des vélos qui y sont installés. Ce dernier aspect apporte une contribution importante à la sécurité routière. Lors de son rangement, il n'occupe qu'une toute petite place dans le fond de la valise. Le principe de cette invention est fort simple. Deux (2) supports rectangulaires sont glissés chacun à l'intérieur d'un tube rectangulaire qui leur sert de base, cette base étant installée de façon permanente, soit sous le pare-choc ou le châssis de la voiture. Sur le support de droite, un fer-angle oblique vers la gauche sert à maintenir le cadrage du vélo lui assurant une bonne stabilité. De plus, le deux (2) supports rectangulaires sont ajustables pouvant ainsi s'adapter à différentes grosseurs de vélo.

Abstract: The invention is directed to an expandable scent for implantation in a body lumen, such a an artery, and a method for making it from a single length of tubing. The scent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements. The individual radially expandable cylindrical elements consist of ribbon-like material disposed in an undulating pattern. The stents are made by coating a length of tubing with an etchant-resistive material and then selectively removing portions of the coating to form a pattern for the stent on the tubing and to expose the portions of the tubing to be removed. This may done by machine-controlled activation and relative positioning of a laser in conjunction with the coated tubing. After the patterning of the tubing, the scent is formed by removing exposed portions of the tubing by an etching process.

Abstract: TITLE               Improvements in Fat-reduced Butters ABSTRACT    An unadulterated, edible water-in-oil emulsion having a reduced butterfat content relative to butter, but containing not less than about 30% by weight butterfat.  The emulsion comprises a combination of native butterfat and, buttermilk, wherein an initial mixture of same in a water-in-oil emulsion at a temperature of from greater than 30 to about 34.0 degrees C is passed through:  a first, upstream scraped surface heat exchanger; an emulsion-working intermediate crystallizer operating under fat crystallization promoting/emulsion softening conditions; and, a second scraped surface heat exchanger.   These are operated under conditions  selected  to  substantially  avoid  any  increase  in  the temperature of the emulsion and to effect an overall reduction of the temperature of to between greater than 14 to about 17.0 degrees C.  The temperature is reduced primarily in the first heat exchanger, remains more  or  less  unchanged  in  the  intermediate  crystallizer,  and  is thereafter generally actively maintained throughout the second heat exchanger. The emulsion is cooled and rotated into and out of heat exchange-surface contacting relation so as to avoid emulsion-channelling therethrough   and   thereby promote   homogeneity   of   butterfat crystallization.   The  crystallized emulsion product  is  relatively physically stable, and is even printable.
