Inventor: MARSHIK GARY JEROME
IPC: E05D15/22
Filed: 1994-01-18
Granted: 1997-11-18
Abstract: The present invention is directed to a locking slide block for slidably and pivotably mounting a window sash to a side member of a window frame having a vertical jamb channel.  The locking slide block has a housing with oppositely disposed sliding surfaces for guiding the housing in the jamb channel.  Operably connected to the housing is a locking means for selectively engaging the jamb channel and locking the housing in a fixed position, and a cam for selectively operating the locking means.  A sash pivot operatively connected to the cam is operably connectable to the sash.  The housing also has a sash pivot retainer spring.  A retaining means is utilized to protect a free second end of the retainer spring from bowing and deforming due to forces applied to the window sash in operation.

Title: Knitting method
Inventor: JEFFCOAT KEITH
IPC: D04B1/22
Filed: 1995-10-27
Granted: 1998-11-03
Abstract: A method of determining the shape of a knitting pattern (Figure 2e)  for continuous knitting of a three dimensional weft knitted object (10) having a two dimensional development (Figure 2c)  in which at least one pair of edges (B,C)  to be knitted together have a large angle  ( ? )  therebetween in excess of x° where x° is the maximum knittable angle between edges  for  the  particular  application of  the  cover.    The method produces a cover having distinct sutures including a first suture (27)(28) formed from knitting together two edges (13)(14) with two sutures (36)(38) extending from one end of the  first  suture  (27)(28)   to  intersect  another  suture (37)(39)  extending from the other end of the first suture (27)(28) at a point (P2).

Title: Sonde de niveau a joint serti
Inventor: COST EVAN
IPC: G01F23/26
Filed: 1994-05-31
Granted: 2000-11-21
Abstract: L'invention concerne une sonde de mesure de niveau dans laquelle toutes les voies de fuite potentielle sont fermées par rétrécissement concentrique de la surface diamétrale extérieure de la sonde à l'aide d'un moyen mécanique tel qu'une sertisseuse ou une étampe rotative destinée à fournir suffisamment de force pour déformer sensiblement uniformément la terre (34), la protection (14), ainsi que des éléments actifs (10) et des isolateurs (12, 16) autour de la circonférence de ladite sonde, de manière à créer des joints d'étanchéité multiple. Une encoche (42) entoure l'élément actif (10) de la sonde au point de sertissage ou de refoulement, afin de ménager une "protection anti-éclatement", de sorte que l'électrode active (10) de la sonde est maintenue en place lorsqu'elle est utilisée dans une cuve à haute pression. Un joint d'étanchéité à la pression situé entre les électrodes et le matériau isolant est également maintenu à l'aide d'un isolateur élastomère revenant à sa forme d'origine à préchauffage, ou une électrode mince qui "donne" un peu lorsque l'isolateur se dilate radialement au cours du chauffage. L'agencement de l'invention élimine ainsi les pièces et les manchons d'usinage coûteux pour produire des joints d'étanchéité à pression.
Patent CA-2166248-C (CA)
Title: Optical character recognition of handwritten or cursive text
Inventor: AL-KARMI ABDEL NASER
IPC: G06V30/10
Filed: 1995-12-28
Granted: 2000-01-04
Abstract: A method and apparatus for optical character recognition particularly suitable for cursive and scripted text in one or more of several languages follows the tracings of the script and encodes them as a sequence of directional vectors.  It reads a preprocessed word or sub-word of interconnected characters as a unit and the characters are accepted in a specific language only if all characters in a unit have been recognized by testing against a first set of language-specific rules without leaving a remainder of any vectors in the unit. If there are vectors remaining unused, it moves a character marker to utilize more or fewer vectors for the current sub-word in order to obtain recognition. If the vectors do not form a character in a first language, the invention consults a second set of language-specific rules and follows similar steps to obtain recognition of one or more characters against the second set of language-specific rules. Also disclosed is a computer-usable medium, for example a magnetic or optical storage diskette, containing code means to execute the invention.

Abstract: The invention relates to a near-field optical microscope, in particular to a scanning near-field optical  microscope (SNOM),   comprising   means   for determining the intensity of light emerging from the near-field at a direction differing from the direction  perpendicular to the surface of the sample to be  examined, preferably emerging at an angle .theta. larger than the critical angle.  Superposing light with   different  azimuth  angles  ? by using   suitable   positioned  mirrors and   beamsplitters  enables  imaging with higher contrast.  The invention allows an accurate control of the distance between the probing tip of the SNOM and the sample by using  the measured  intensity in a feedback loop.

Patent CA-2178369-C (CA)
Inventor: HEGGIE WILLIAM
IPC: C07C237/46
Filed: 1996-06-06
Granted: 2001-10-16
Abstract: The present invention describes a process for the purification and crystallisation of Iopamidol, wherein 1-propanol, or 2-propanol, is added to an aqueous solution ofIopamidol followed, if necessary, by azeotropic distillation to reduce the quantity of water in relation to the quantity of propanol, and thereby ensure an high yield. The aqueous solution can be prepared either by the dissolution of crude Iopamidol inwater or directly from the reaction in which the Iopamidol is formed.   The present invention presents advantages for the routine production of Iopamidol since the crystallisation is straightforward to perform, can be easily controlled and is reproducible at an industrial scale.
