Title: Toroidal cylinder internal combustion engine
Inventor: WHITE W
IPC: F01C1/46
Filed: 1981-06-25
Abstract: A pair of toroidal cylinders (2, 4) are arranged in pairs with their transverse axes in colinear alignment. Each toroidal cylinder includes at least one piston (6A-6D). The pistons within adjacent toroidal combustion chambers rotate in opposite directions and combustion is induced at the moment when two pistons disposed within two adjacent toroidal combustion chambers pass. A combustion port (24A, 24B) is provided between the adjacently disposed toroidal cylinders. The combustion process occurs within the port and within internal combustion chambers provided within each of the pistons. This port allows a single combustion to propel the pistons in each of the cylinders in opposite directions. The pistons drive counter-rotating drive shafts (10, 12) which are constrained in a time relationship. A flap valve (44) is provided in the upstream end of each piston to allow the piston to accept fresh intake gases. Intake and exhaust valves (30A, 30B, 32A, 32B) are also provided within the cylinder walls to control the intake of a fresh charge and to allow the combustion by-products to be exhausted.

Title: Electrical connector
Inventor: PORTER WARREN WESLEY
IPC: H01R12/87
Filed: 1982-11-08
Abstract: An electrical connector (1) for a printed circuit board (16) permits a low insertion force while providing a high contact force. The connector (1) includes a plurality of resilient electrically conductive pins (18) and a carrier (22) having mounted therein conductive levers (21) which cooperate with the pins (18). A board (16) inserted into the connector engages the carrier (22) thereby moving first ends of the levers (21) into engagement with predetermined points (45) on the edge contacts (26) of the board (16). As the board (16) is further inserted, the pins (18) are deflected to maintain the first ends of the lever (21) in engagement with the predetermined points (45). The levers (21) have sharpened ends and are effective to pierce an oxide coating which may form on the edge contacts (26). A spring element (41) acts on the carrier (22) to ensure the levers (21) are not in the path of the printed circuit board until after the printed circuit board makes contact with the carrier.
Patent WO-8303508-A1 (WO)
Title: Dial pulsing circuit
Inventor: HUIZINGA DONALD DEAN
IPC: H04M1/31
Filed: 1983-03-23
Abstract: In order to provide push-button telephone service to those telephone systems not equipped to respond to multifrequency dialing signals, it is necessary to convert push-button dialed digits into conventional dial pulses. A pulse train consisting of make and break intervals representing the dialed digit is electronically converted (107) into a corresponding series of make and break intervals on the telephone line (102, 103) by switching (106, 108-1, 108-2) a pulsing transistor (101) that is in series with the telephone line ON and OFF. In order to keep the pulsing transistor ON during nondialing intervals and during each make interval, and not attenuate the voice signal, the pulsing transistor is biased by an adjustable current source (105). The current needed to bias the pulsing transistor ON is linearly related to the telephone line current flowing through the emitter-collector path of the transistor, and which varies considerably from station-to-station. In order to minimize the current needed to bias the pulsing transistor, a current sensor (104) derives a signal proportional to the line current which, in turn, is fed back to the current source (105) in order to adjust the bias current to be proportional to the line current.

Abstract: Le dispositif comparateur de chaînes (105) permet la comparaison de chaînes de caractères à vitesses élevées dans un circuit (103) d'un système d'ordinateur (101). Le dispositif de comparaison de chaînes (105) effectue une mesure numérique du degré de similarité entre les chaînes de caractères comparées en utilisant un algorithme mathématique. L'algorithme est résolu par un nouveau dispositif de comparaison de chaînes (105) ou par un nouveau programme dans un système d'ordinateur (101). Le circuit (103) du système, sous la forme d'une puce peut être connecté dans une boucle de mémorisation d'un sytème d'ordinateur (101) pour localiser et extraire rapidement des enregistrements qui sont très similaires à l'interrogation introduite. Les interrogations inexactes localisent rapidement des enregistrements semblables par rapport aux mesures de similarité relatives aux chaînes de caractères. La méthode de comparaison de chaînes de caractères utilisant le dispositif amélioré de comparaison de chaînes peut fournir une réponse rapide aux interrogations dans un temps de calcul proportionnel à la longueur moyenne de la chaîne de caractères.

Abstract: Ce joint mécanique permet une rotation relative entre deux articles (l'un desquels peut être un dispositif fixe), sur un axe arbitraire. Le joint présente une plage de rotation angulaire aussi étendue que sa plage d'articulation, mais autant de degrés de liberté qu'un joint universel ou à bille. Il permet la transmission, entre les objets, d'une force ou d'un flux (par ex. d'électricité, de gaz ou d'un liquide), ou des deux. Dans une forme d'exécution, le joint est simplement mécanique et est formé de deux toroïdes à interverrouillage serré (21, 31). La section transversale inférieure de chaque toroïde est dimensionnée de manière à correspondre exactement à l'ouverture centrale de l'autre toroïde; un point de liasion (11, 41) sur chaque toroïde permet la fixation d'un article. Dans une variante, l'invention a une structure interne consistant en deux anneaux interverrouillés et fixés mutuellement (481, 491) ou similaires. D'autres structures, généralement annulaires (421, 431) chevauchent les structures internes.

Title: Optical switches using cholesteric or chiral nematic liquid crystals
Inventor: SHANKAR NARENDRA K
IPC: G02F1/1333
Filed: 1990-05-03
Abstract: Fiber optic switches (10) using layers of cholesteric or chiral nematic liquid crystals (CLCs) are disclosed. The CLC layer (12) acts both as a polarization beamsplitter and as a reflector by decomposing incoming unpolarized light into two orthogonal circularly polarized components. In a number of embodiments, switchable waveplates (14, 16) are employed to switch the polarization direction of each of the polarization components. The components are then reflected back toward the CLC layer (12) where they are recombined into a transmitted unpolarized beam (26). The direction of transmission depends on the circular sense of the polarized components, and therefore on the state of the switchable waveplates (14, 16). In other embodiments, the CLCs are used actively by exposing them selectively to electric or magnetic fields or to heat which cause a phase change that temporarily neutralizes the circular polarization effect. In this manner, the CLCs can be used as switch elements by themselves.

Abstract: An apparatus (21) for forming a butt seam between opposed edges of resiliently compressible fabric sheets (28, 29), such as foamed neoprene for wet suits and dry suits. The apparatus (21) includes fabric manipulating assembly (23) which continuously compresses the sheets proximate and inwardly of the edges (32, 33), preferably by a roller assembly (26, 27), to form opposed shoulders or areas (43, 44) that will permit the application of a lateral force to firmly press the opposed edges (32, 33) of the flexible and compressible sheets (28, 29) tightly together during movement and bonding along the seam. The apparatus (21) preferably includes adhesive activation means (24) in the form of an ultrasonic transducer (91) which contacts the neoprene pieces in advance of compression rollers (26, 27) to activate a dry neoprene cement carried on the edges of the fabric pieces. A method for forming the butt seam is described, as are alternatively adhesive activating assemblies and a seamed neoprene fabric sheet.
