Abstract: ABSTRACT     A bone screw to be used in combination with a correction and supporting apparatus is provided. With such correction and supporting device the problem arises that when two vertebrae are expanded, the vertebra in between said vertebrae is shifted to the inside of the curvature of the spinal column. To correct or prevent such lateral shifting a bone screw is provided having a threaded shaft (60) and a segmented or fully spherically shaped head (61), an extension (62) having a support face (64) fitting on said head (61) being provided. An element (66) is connected to said extension (62). Said element (66) serves to connect said extension with a rod (29,30) at said correction and supporting apparatus. Element (66) and extension (62) are connected such that the distance between the support face and said element may be adjusted.

Abstract: 17 ABRÉGÉ DESCRIPTIF Procédé et dispositif de caractérisation et de localisation en temps réel de singularités d'une image numérisée, notamment pour la reconnaissance de formes dans un traitement d'analyse de scène Les singularités constituant les points caractéristiques de l'image sont des points de contour à forte courbure tels que des coins ou régions de petite taille, l'image étant formée d'une trame bidimensionnelle de pixels présentant chacun un niveau de gris déterminé. Le dispositif de l'invention comprend : des moyens dérivateurs (10) approximant, pour chaque pixel à analyser, les dérivées partielles d'ordre 2 de la fonction de niveau de gris de l'image (F(x,y)); des moyens caractérisateurs (23, 30), déterminant à partir de ces dérivées un attribut (.lambda.2) représentatif de la caractéristique recherchée et affectant cet attribut au pixel ainsi analysé ; et des moyens localisateurs, recherchant parmi les pixels de l'image ainsi analysés les points maximisant ledit attribut. Très avantageusement, les moyens dérivateurs (10) comprennent des moyens convolueurs effectuant une convolution de la fonction de niveau de gris de l'image (F(x,y)) avec des fonctions correspondant aux dérivées partielles d'ordre 2 d'une fonction de régularisation, cette fonction de régularisation permettant d'atténuer le bruit présent dans l'image. De préférence, l'attribut choisi est la seconde valeur propre de la matrice des dérivées secondes, et la fonction de régularisation est une fonction gaussienne, notamment une fonction gaussienne centrée.

Title: Printer driving apparatus for line printer
Inventor: IGUCHI KESAYOSHI
IPC: B41J2/30
Filed: 1991-08-14
Abstract: A printer driving apparatus for a line printer comprises:  a measuring circuit to measure the number of print dots; and a driving circuit which can change drive timings of dots of a print head in correspondence to a print ratio in each print cycle.  When the number of print dots is small, an interval between strobes is narrowed.  When it is large, an interval between strobes is widened.  Thus, a high-speed printing can be performed in the case of using the power source of the same capacity.  When a high-speed printing is not required, the capacity of the power source can be reduced.

Patent CA-2061243-A1 (CA)
Inventor: STANEVICH KENNETH W
IPC: H01B17/58
Filed: 1992-02-14
Abstract: The invention provides a connector for passing continuous insulated electrical conductors such as pins or multi-stranded wire through a surface or bulkhead, while preventing leakage of liquids and gases along the conductors, especially between gaps in  the  strands.   An  exemplary  connector  of  the  invention comprises a body having seal-zone openings in which a sealant is applied to and cured around a compressed bared section of multi-stranded wire.  The body contains strain relief members adjacent to the sealed openings to provide longitudinal as well as  transverse  strain  relief.   A sealant member  and  radially spaced clasps are located around the sealed openings and strain relief  members  so  that  the  connector  may  be  removably twist-locked  onto  a  bulkhead  without  disturbing  the  sealed wires.   The  invention  also  provides  a  method  for  achieving  the sealed pass-through of electrical conductors.

Title: Bicycle frame lug with integral cable guide
Inventor: MULLER MARC
IPC: F16C1/26
Filed: 1992-07-08
Abstract: ABSTRACT          A bicycle frame lug comprises a hollow body having at least two cylindrical sockets extending along separate, angularly divergent axes and adapted to receive bicycle frame tubes at a bicycle frame joint.  At least one cable guide member is formed integrally with an outside surface of the body.  This differs from the prior art practice of brazing or welding cable guide members to the frame tubes themselves at the risk of weakening or degrading the thin aluminum or steel alloy materials.  The integral cable guide members reinforce the lugs, providing added strength to the frame without adding weight.

Filed: 1991-04-17
Abstract: A DNA fragment, encoding all or an insecticidally-effective part of a Bacillus thuringiensis crystal protein, is modified by changing A and T sequences to corresponding G and C sequences encoding the same amino acids. These changes are in a plurality of translational codons of the DNA fragment that would otherwise directly or indirectly cause a nuclear event which would negatively control transcription, nuclear accumulation and/or nuclear export of the mRNA. The A and T sequences are changed into G and C sequences in translational codons of at least one region of the gene which, during transcription, would otherwise have thereon a relatively low percentage of RNA polymerase II as compared to another adjacent upstream region of the gene.

Title: Portable test receiver for remote monitoring system
Inventor: CAHALAN IRVING W
IPC: G08C25/02
Filed: 1993-04-16
Abstract: ABSTRACT    A portable test receiver for field maintenance of a remote sensor monitoring  system for underground transformers.   The apparatus uses a phase locked loop method to demodulate the DPSK modulation of the remote monitor transmitter.  The apparatus is battery operated and easily moved to permit monitoring of spot networks  and critical  locations  for maintenance work.   The apparatus features a single software driven display offering good visibility with low current drain.   Decoding the transmitter signal is accomplished by using the crystal oscillator circuit of the transmitter is used to generate a reference which is compared to the transmitter  signal to detect phase  flips.  Since the apparatus is battery-powered, there is no AC power to provide "zero" crossing points of the monitored transmitter.  Bit timing is provided by taking advantage of the nulls at the 60 cycle "zero" crossings found in the transmitter signal.

Inventor: SIMON JOHN G
IPC: A61M25/00
Filed: 1991-12-24
Abstract: The present invention is a removable drug delivery system used by patients suffering from lower urinary tract infections.  Infections involving bacteria in the urine and/or in the superficial regions of the urethral and bladder tissues should be highly amenable to treatment by the release of antibiotics into the urine in the bladder, or onto the walls of the urethra.
