Patent CA-2160617-A1 (CA)
Inventor: ROLL RICHARD ALLEN
IPC: G02B6/38
Filed: 1995-10-16
Abstract: An improved method is provided for applying optical fiber support members (17, 18) to a pair of fixtures such as vacuum chucks (24, 25) such that the fixtures can thereafter be used to clamp the support members to opposite sides of an array of optical fibers (14). The improvement comprises arranging the optical fiber support members in a magazine (29, 30) and bringing the two fixtures into proximity with a magazine. Automatic apparatus (33, 34) is used for urging a pair of optical fiber support members from the magazine onto the two fixtures such that the support members adhere to the fixtures. After placement of the support members on the fibers, the cycle is repeated.
Patent CA-2160643-A1 (CA)
Inventor: LAWARE GUS
IPC: B65D83/14
Filed: 1995-10-16
Abstract: An overcap for a self-pressurized aerosol container is disclosed that dispenses the contents of the container as an aerosol spray in either an intermittent or continuous manner. The overcap is particularly useful in conjunction with the delivery of a fine particle size insecticide spray or fog and is economical to manufacture because it has few moving parts. The overcap comprises a shell containing an aerosol actuator button that further contain mutually cooperable, releasably locking engagement means. Intermittent aerosol dispensing is achieved without interference by the engagement means. Continuous aerosol dispensing is achieved by having the user position a movable engagement means so that it engages the other engagement means while the actuator button is held by the user in its dispensing position. The user then releases the actuator button and the engagement means retain the actuator button in the atomization position for continuous spraying. The second engagement means may be released to stop the continuous spray simply by again pressing the actuator button.

Title: Umbilical cord clamp
Inventor: REYNOLDS JAMES L
IPC: A61B17/122
Filed: 1995-10-31
Abstract: A unitary clamp integrally structured from two U-shaped members respectively disposed one from the other by an interjoining web between proximate arms of each U-shaped member, distal ends of each member having latching means so as to latch, simultaneously, both U-shaped members into a closed position and the interjoining web sheets spacially disposing each U-shaped member into adjacent closing engagement about an umbilical cord.  The web sheets are cut by a pair of scissors to sever the cord and one of the U-shaped clamp members is thus attached to the umbilical cord attached to the abdomen of an infant while the other to the umbilical cord connected to the placenta.  On voiding of the placenta, the latter is discarded.  When healing of the umbilical cord to the infant is achieved, that clamp member may be removed or discarded.

Title: System and method for transmitting compressed data or pre-compressed data based on a preset compression ratio
Inventor: KAWASHIMA TETSUJI
IPC: H03M7/48
Filed: 1995-04-21
Abstract: A difference/compression ratio calculating means 76 in a data processing means 71 of a data transmitting apparatus according to the present invention calculates an actual difference and an actual compression ratio based on the data length of pre-compression data received from a data source 2 through pre-compression data receiving means 74 and the data length of compressed data outputted from a data compression circuit 67. If the actual difference is equal to or greater than a preset difference a and the actual compression ratio is equal to and greater than a preset compression ratio .beta., then the compressed data is transmitted to a data destination 3 through a transfer request data output means 79. Otherwise, the pre-compression data is transmitted to the data destination 3. With this arrangement, it is possible to prevent a phenomenon in which the size of compressed data which occupies a storage area in the data destination 3 is substantially the same as the size of uncompressed data which occupies the storage area, and also to avoid wasteful data expansion in the data destination 3.

Title: Method of controlling the hydration behaviour of gipsum in the manufacture of composite materials
Inventor: SCHMELMER BERNHARD
IPC: C04B40/02
Filed: 1994-06-23
Abstract: Described is a method of controlling the ratio of the hydration time (HZ) to the open time (OZ) in the manufacture of composite materials. The mixtures from which the boards are manufactured consist of hydratable calcium sulphate, in particular gipsum binders, aggregates, fibres, water additives and other additives The HZ:OZ ratio is less than 1. This is achieved by adding a retarder-accelerator combination and using pressure. This gives a maximum reduction in the hydration time for the manufacturing process relative to the open time.

Title: Combination body and back bath scrubber
Inventor: WEILL THEODORE C
IPC: A47K7/02
Filed: 1996-01-31
Abstract: An article for use when bathing includes first and second mitts each having a pocket-defining end for receiving a person's hand and a flap extending from the pocket-defining end.  Each mitt is made from opposing panels sewn together to form a pocket in the shape of a person's hand, with one edge of the mitt being left open for access to the pocket.  A transverse slot extends parallel the one edge spaced from the open edge to form a handle.  A patch of hook-and-loop material is sewn onto the flap and a mating patch of hook-and-loop material is sewn onto the "palm" of the pocket-defining end.  The patch and mating patch are releasably engageable to hold the mitt in a folded position, which is conveniently sized to facilitate use as a single-handed scrubber.  The patches on the flaps of the first and second mitts is also releasably engageable so that the mitts can be attached to form an elongated article useful for scrubbing a person's back.

Patent CA-2177583-A1 (CA)
Inventor: LAMPE ROSS W
IPC: H04L27/12
Filed: 1995-09-26
Abstract: Des signaux à modulation de phase constante (CPM) tels que des signaux quaternaires CPFSK sont filtrés pour limiter leur largeur de bande tout en réduisant simultanément la quantité de modulation d'amplitude et les interférences entre symboles introduites par ce procédé de filtrage. En concevant le filtre de modulation sous la forme d'un filtre à réponse impulsionnelle finie, de façon à n'ajouter qu'une quantité nominale et régulée de modulation d'amplitude, on peut utiliser des amplificateurs de puissance non linéaires à fort rendement pour émettre les signaux CPFSK filtrés. Bien que le filtre ajoute une faible quantité de modulation d'amplitude et d'interférence entre symboles, les récepteurs de signaux numériques à processeur démodulent de manière satisfaisante ce type de signaux à l'aide d'algorithmes à estimation de séquences tels que l'algorithme de Viterbi. Ainsi, le filtrage des signaux CPM permet de réduire le spectre du signal émis tout en traitant les interférences entre symboles résultant de la quantité régulée de modulation d'amplitude ajoutée par le filtrage. Le recourt à des largeurs de bande rétrécies associées à des amplificateurs de puissance non linéaires à haut rendement rend cette invention particulièrement adaptée aux radiocommunications mobiles à bande étroite.

IPC: G10K11/00
Filed: 1995-01-23
Abstract: Each of the acoustic transducers (el-ements) of an  array has  a  maximum  di-mension of less than .lambda..  They are located at the vertices (4, 6) of a regular polyhe-dron (14), which may be an  icosahedron (12 elements), or a  dodecahedron (20 ele-ments).  This placement effectively locates the  elements on  the  surface of a sphere with diameter selected to  provide  an in-terelement spacing of .lambda./3  to  2.lambda./3.  The signals are delayed for phasing  to  form  di-rective "beams".  A second  array  includes elements located at the vertices (6, 34) of a smaller polyhedron (600A)  centered  at  the same point and included within the  first ar-ray,  and operated  at a higher  frequency than the  outermost  array.  In order to reduce the effects of  shadowing, the  locations of the transducers of  the  smaller  included array (600A)  are selected to lie  on  radials (630) passing through the  centroids  (614)  of the faces of the polygon defining  the  larger ar-ray (14).
