Title: Single-phase inverter circuit for conditioning and converting dc electrical energy into ac electrical energy
Inventor: GONZALEZ SENOSIAIN ROBERTO
IPC: H02M7/5387
Filed: 2006-07-31
Abstract: The invention presents a structure for the conversion of direct current electric power into alternating current electric power,  characterised in that  it is simple, highly efficient and minimises the problem of electromagnetic compatibility. The circuit includes, in its first preferred embodiment, six switching elements governed by a command unit, four switches forming an H-bridge (T1, T2, T3, T4) and two auxiliary switches (T5D, T6D), and two auxiliary diodes (Daux1 and Daux2). The elements of the H-bridge switch at grid frequency, whereas T5D and T6D switch at high frequency by means of pulse width modulation (PWM), or other appropriate modulation techniques. The voltage of these auxiliary switching elements (T5D, T6D) is limited topologically to half the direct current input voltage (Vin), thereby reducing switching losses and resulting in a high performance converter.

Patent EP-2603623-A4 (EP)
Title: Toughened polylactic acid fibers
Inventor: TOPOLKARAEV VASILY A
IPC: C08L67/04
Filed: 2011-07-06
Abstract: Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid. These domains have a particular size, shape, and distribution such that upon fiber drawing, they absorb energy and become elongated. This allows the resulting composition to exhibit a more pliable and softer behavior than the otherwise rigid polylactic acid. Through selective control over the components and method employed, the present inventors have discovered that the resulting fibers may thus exhibit good mechanical properties, both during and after melt spinning.

Inventor: KOHLER RAMON C
IPC: F16C1/10
Filed: 1980-10-09
Abstract: A flexible cable (24a) connected at one end to a throttle lever (not shown) is displaceable in a telescoping manner relative to a protective sheath (22) and is pivotally connected at its second end to a connecting lever (28, 28'). The connecting lever (28, 28') and a portion of the flexible cable (24a) reside within a housing (12) which is attachable to a mounting member (14). The connecting lever (28, 28') has splines which are circumferentially engageable with a splined governor shaft (16, 16') which protrudes from the side of the member (14) and extends into the housing (12) through an opening (12a). A cover (32) is attachable to the housing (12) in closely spaced axial relationship with the connecting lever (28, 28') so as to prevent its disengagement from the governor shaft (16, 16'). The connecting lever (28, 28') extends into the opening (12a) to insure access to the connecting lever (28, 28') when it is disengaged from the shaft (16, 16'). The flexible cable (24a) has two extreme displacement limits (E, F) which correspond to two extreme rotative limits (E, F) for the shaft (16, 16'). Method and apparatus are provided for maintaining the calibration and correspondence between the cable's displacement limits (E, F) and the shaft's rotative limits (E, F) when the connecting lever (28, 28') is disassembled and reassembled with the governor shaft (16, 16').

Title: A maskless process for applying a patterned coating.
Inventor: FEFFERMAN GERALD BURT
IPC: H05K3/00
Filed: 1982-12-08
Abstract: A process for applying a patterned coating to a circuit board (31) without the use of a patterning mask. A surface (30) of the circuit board is coated with uncured material (32) having a cure reaction which is inhibited by the presence of oxygen. The thickness of the material on land areas (34) surrounding holes (36) through the circuit board is reduced by causing a portion of the material to flow into the holes. The material is then exposed, in the presence of oxygen, to an energy source which advances the cure reaction only of sublayers (37) of the material which are isolated from the oxigen by overlayers (38) of the material. Surface layers of the material, including substantially the entire thickness of the reduced thickness portions of the layer, remain uncured, allowing subsequent selective removal of the uncured portions of the material.

Title: Method for installing cable using an inner duct.
Inventor: CONTI ALLEN C
IPC: G02B6/44
Filed: 1985-06-24
Abstract: An inner duct (30) which can fit inside a duct (10) and extend along a length thereof for receiving communication cable, particularly a light-guide cable. The inner duct has a continuous side wall with protruding ribs (35, 36) on the inside and outside surfaces to maintain an effective supply of lubricant during the installation of the inner duct and cable in the inner duct. The ribs on the inside surface (35) of the inner duct guide cable during placement operation. It is preferred to install a plurality of inner ducts into a duct during which the ribs on the inner duct interlock with one another to prevent spiraling. The ribs also facilitate the dissipation of heat due to friction and ambient sources of heat. Conventional techniques of replacing cables in existing ducts do not introduce additional inner ducts. The problem of damaging cable by friction arising during pulling of the cable is eliminated by the use of the inner ducts of the present invention.

Abstract: Le procédé d'apprentissage/reproduction pour engin de terrassement ci-décrit est le procédé utilisé pour l'automatisation des opérations d'une pelle hydraulique et d'autres engins de construction. Les opérations effectuées par un opérateur sur l'actuateur d'un engin de terrassement sont mémorisées et reproduites afin d'effectuer automatiquement la même opération. Le procédé décrit permet notamment d'effectuer la même opération qu'au moment de l'apprentissage même si la charge sur l'actuateur de l'engin de terrassement lors de l'apprentissage n'est pas la même lors de la reproduction. A cet effet, on enregistre la quantité de fluide fournie par la pompe au moment de l'apprentissage et le débit d'alimentation à chaque actuateur de l'engin de terrassement. Lorsque la quantité de fluide fournie par la pompe se modifie en fonction de la variation de la charge au moment de la reproduction, on effectue une commande de sortie du moteur, afin que la quantité de fluide fournie par la pompe corresponde à celle fournie lors de l'apprentissage. Lorsque le débit d'alimentation de l'actuateur de l'engin de terrassement se modifie, une soupape de régulation de débit montée dans son circuit d'admission est commandée de sorte que la quantité de fluide fournie par la pompe corresponde également au débit au moment de l'apprentissage.
Patent EP-0462182-A4 (EP)
Title: Matrix metalloproteinase peptides: role in diagnosis and therapy
IPC: C07K16/00
Filed: 1990-03-01
Abstract: A family of metalloproteinases exist which cleave extracellular matrix molecules. These metalloproteinases are secreted in a latent inactive form and require activation in order to specifically cleave the preferred substrate. A series of peptides have been prepared based on the complete sequence analysis of type IV procollagenase. Peptide inhibitors were synthesized which correspond to cysteine repeat regions and histidine containing regions; the mechanism of action of these peptides involves inhibition of binding of the enzyme to the substrate. Peptide inhibitors were synthesized which correspond to the peptide cleaved off during activation, and constitute a novel class of metalloproteinase inhibitors. These inhibitors are members of a series of peptides which contain the core amino acid sequence RKPRC or analogs thereof. The cysteine residue is required for activity. Affinity purified antibodies directed against specific peptides can be used to a) detect any general metalloproteinase enzyme with the sequence in part VAAHE or PRCGNPD, and distinguish it from other known members of the metalloproteinase family, b) block functional domains resulting in the inhibition of enzyme activity, and c) distinguish latent from activated forms of the enzyme.
