Title: Continuous plastics molding process and apparatus
Inventor: KEMERER W JAMES
IPC: B29C48/09
Filed: 1991-01-17
Granted: 1996-03-05
Abstract: A  continuous  process  and  apparatus  for  forming products  from thermoplastic materials  between  top  and bottom mold carriages is disclosed.  Each carriage has a frame  including  a  backup  plate  coated  with  a  low coefficient  of  friction material  over  which  slides  a continuously moving belt mold.  The belt mold is comprised of a flexible silicone rubber mold adhered to a fiber belt.          The silicone rubber mold has a surface of desired shape for mating with an opposed mold surface to form a continuously moving  mold  channel  into  which  is  fed  thermoplastic material at a moldable temperature.  After molding the hot plastic material, localized surface heat of the belt molds is removed by cold air blown against the belt mold.  The low coefficient of friction backup plates have numerous air-bearing holes for feeding high pressure air between the low coefficient of friction plates and the moving fiber belt to reduce friction and reduce wear.  The fiber belts are guided and driven by a wide V-shaped central ridge or by twin-wide V-shaped ridges near their edges.   The V-shaped ridges fit into and mesh with corresponding geared teeth in grooves of the sprocket drive rolls and operate to maintain alignment of the mold belts. An electric drive motor, with or without the assistance of a torque motor, drives both belt molds in unison to maintain their relative alignment.  Electric screw jacks raise the top carriage, extend and retract the grooved exit rolls, and fine tune the alignment of the moving belt molds by adjusting the grooved exit rolls and move the machine to and from the extruder.

Patent CA-2051866-C (CA)
Title: Call set-up and spectrum sharing in radio communication on system with dynamic channel allocation
Inventor: KOOHGOLI MAHSHAD
IPC: H04M1/72511
Filed: 1991-09-18
Granted: 1997-02-25
Abstract: The call set-up technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining the radio traffic channel upon which to set-up a new call. Communication between the base station and subscriber terminal is carried out on a signalling channel until the traffic channel is chosen.  Calls are set-up so that they proceed on the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal.  The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service.  This subset is comprised of those channels having little interference, as measured by the base station, and which, additionally, are not reserved exclusively for stationary, fixed-allocation services in the geographic location of the base station.  The call set-up technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.  The technique also facilitates sharing of the radio spectrum with stationary, fixed-allocation services because there is no need to program each subscriber terminal to avoid the spectrum allocated to the fixed service.

Title: Fitted belt for absorbent garment
Inventor: NEW NANCY ANN
IPC: A61F13/49
Filed: 1990-12-07
Granted: 1998-03-31
Abstract: Disclosed is a disposable absorbent garment (10, 10", 10"') having a belt (12, 12', 12", 12"'). The belt may either be integral with (12", 12"') or detachable (12, 12') from the absorbent portion of the garment.  The belt (12, 12") is arcuate so that one laterally extending edge (16, 16") of the belt is longer than the other laterally extending edge (16, 16") of the belt.  This arrangement provides a better fitting belt which more discretely conforms to the contours of the wearer and is less noticeable under clothing.  Alternatively, the belt (12"') may have a portion which is worn relatively high on the wearer's back, portions which extend diagonally downward to the front of the wearer and a portion which is worn relatively low, below the stomach of the wearer in front.  This arrangement provides a belt (12"') which generally does not interfere with the portions of the wearer's body which encounter large ranges of motion during normal movements of the body.

Abstract: Méthode permettant d'améliorer la transmission d'information sous forme de paquets de données, conformément à un protocole de mise en file répartie. En combinant les mesures de l'invention avec des techniques d'effacement de créneaux temporels et avec des protocoles de mise en file tels que le DBQB (Distributed Queue Dual Bus) et le D3Q (Dynamic Distributed Dual Queuing), on obtient un protocole qui permet d'utiliser plus efficacement la capacité du système de transmission.  cette fin, conformément à l'invention, chaque unité d'accès qui est capable d'effacer des données est aussi capable de remettre à zéro les bits de demande reçus : ces unités d'accès enregistrent le nombre de bits de demande à remettre ainsi à zéro pour le canal de transmission pertinent et l'unité d'accès qui reçoit ledit bit de demande remet à zéro un bit de demande sur le canal de transmission si le nombre de bits de demande qu'elle doit remettre à zéro sur ledit canal est supérieur au nombre de bits de demande qu'il lui reste à transmettre sur ledit canal. Ces dispositions empêchent les demandes de demeurer inutilement dans les compteurs des unités d'accès. De plus, l'invention prévoit des mesures qui permettent d'utiliser le principe des deux protocoles dans une structure en anneau, ce qui autrement provoquerait inévitablement des difficultés considérables.

Abstract: Present-day limitations of the conventional touch-tone keypad are overcome permitting alphabetic information to be entered into a distant computer. The caller speaks a speech portion into a telephone handset, and then types out the speech portion on the touch-tone keypad. The computer receiving the call converts the spoken voice in-formation into a form suitable for additional digital processing, as by extracting speech-recognition features from the spoken informa-tion (32). The computer processes the typed numeric string into a list of all the possible combinations of characters it could represent (31). The extent of correlation between the features of the spoken speech portion and each of the combinations is determined (33), and the combination having the highest correlation is taken to be the speech portion entered by the user (34).

Inventor: BAKER BRUCE R
IPC: G06F17/27
Filed: 1991-08-08
Granted: 2002-10-22
Abstract: A Natural Language Pro-cessing System utilizes a symbol parsing layer (5) and an intelligent word parsing layer (5) to produce a syntactically or pragmatically cor-rect output.  A plurality of polysem-ic symbol sequences are input through a keyboard with semantic, syntactic, or pragmatic segments in-cluding agent, action and patient segments, for example.  One poly-semic sequence is input from each of the three segments of the key-board (1).  A symbol parsing device, then parses each symbols in each polysemic symbol sequence to access a previously stored word, morpheme, or phrase.  The accessed word, morpheme, or phrase (50) corresponds to the input polysemic symbol sequence and further corresponds to one of the designated agent, action or patient segments.  Each accessed word, mor-pheme, or phrase further accesses corresponding and previously stored grammatical and semantic information.  An intelligent word parsing layer (5) subsequently applies each of the plurality or words morphemes, or phrases to a predetermined hierarchy of rules based upon the accessed grammatical and semantic information.  The intelligent word parsing device subsequently parses the received plurality of accessed words, morphemes, or phrases into a syntactically or pragmatically correct output.

Title: Apparatus for shear-cutting a stack of amorphous steel strips
Inventor: HOUSER WILLIAM KIRK
IPC: B23D15/08
Filed: 1993-03-11
Granted: 2001-12-11
Abstract: For shear-cutting a stack of thin strips of amorphous steel along a cutting plane that extends transversely of the stack, I utilize apparatus that comprises two blades that are positioned at the start of a cutting operation on opposite sides of the stack. Each of the blades has a first surface for engaging one side of the stack and a second surface extending transversely of the first surface and generally parallel to said cutting plane arid intersecting the first surface at a corner. The first surface of each blade is disposed at a predetermined rake angle with respect to a reference plan extending through a point on the corner of the blade and normal to said cutting plane. The apparatus is further characterized by the following features that cooperate to impart to the blades an exceptionally high resistance to wear: (i) the sum of the rake angles is of a negative value and between 5 and 35 degrees, and (ii) both blades are of a cemented carbide cutting material that consists essentially of tungsten carbide particles and cobalt particles compacted under high pressure and sintered at a temperature exceeding the melting point of the cobalt, the tungsten carbide particles being, on average, of submicron size and the cobalt constituting more than 15 percent and about 16 percent by weight of the cutting material.
