Title: Communication package with apparatus and method for storing and retrieving a permanent message
Inventor: HARMAN JEFFREY A
IPC: G10L19/00
Filed: 1996-03-29
Abstract: A communication package has, enclosed in a storage disc, a voice chip connected by power input bus terminals to a renewable, battery power system which provides easy battery accessibility. The storage disc preferably contains an acoustically resonant chamber and diffusion apparatus and preferably contains a removable barrier between the power system and the power input bus terminals that must be removed before the voice chip can be energized (Figure 3). A voice message is stored in the communication package by recording the voice message into a recording unit, replaying the voice message, optionally re-recording at least a portion of the message until the replay is satisfactory, converting the message to a compressed, digital "sound file" and then downloading this "sound file" onto the voice disc. Identifying information is converted into a compressed, digital "text file" and transmitted with the "sound file" to be displayed as a visual identification of the "sound file" (Figure 4).

Patent CA-2222072-A1 (CA)
Inventor: HOVE LEO
IPC: E01C19/10
Filed: 1996-05-24
Abstract: Compte tenu des inconvénients propres à l'application classique à chaud du bitume, on s'est efforcé de remplacer cette méthode par une technique à froid qui consiste à appliquer un mélange de pierres et d'émulsion de liant bitumineux tenant lieu de liant ("rupture") une fois le matériau posé. Cela requiert un degré de planification et une capacité de production élevée dans les usines de bitume et par ailleurs, l'utilisation de la technique à froid est limitée en ce qui concerne la haute viscosité souhaitable pour le liant bitumineux. L'invention se rapporte à un procédé qui consiste à utiliser deux groupes de matériaux dont la préparation est distincte et que l'on peut stocker afin de prélever à tout moment la partie nécessaire aux applications. Il suffit de mélanger ces fractions avant l'application, de sorte que les émulsions de liant respectives agissent comme agents de rupture l'une par rapport à l'autre. Il est possible d'utiliser du bitume à haute viscosité dans les deux émulsions. On décrit également la fabrication et la distribution des produits en deux groupes séparés en tant qu'aspects concernant les usines.
Patent CA-2222990-A1 (CA)
Inventor: CECCON HARRY L
IPC: A61B18/20
Filed: 1996-06-03
Abstract: A flashlamp-excited dye laser generating light pulses for therapy has a circulator which circulates a gain media through a dye cell. A controller coordinates operation by triggering flashlamps to excite the laser gain media while the circulator is circulating the gain media. This operation enables the generation of laser light pulses with a duration of at least one millisecond. If the flow velocity of dye solution is great enough such that the new solution enters the resonant cavity before the solutions in the cavity are substantially spent, ultra-long pulses with high fluences are possible. Specifically, longer pulses of up to 50 msec can be achieved with energies of up to 50 Joules. These energies enable reasonable spot sizes, which makes the invention relevant to dermal therapy, for example.
Patent CA-2223321-A1 (CA)
Title: Timing adjustment control for efficient time division duplex communication
Inventor: SCOTT LOGAN
IPC: H04B1/707
Filed: 1996-05-28
Abstract: A system for time division duplex communication over a single frequency band wherein guard time overhead is reduced by active adjustment of reverse link transmission timing as a function of round trip propagation delay. Responding to a polling message from the base station, a user station seeking to establish communication transmits a reply message. The base station using a propagation delay calculator (812) calculates the distance of the user station by measuring the propagation delay with respect to receipt of the reply message and a timing control unit (806) and transmitter (807) for sending a timing adjustment command to the user station instructing it to advance or retard its timing. Thereafter, the base station monitors the user station transmissions and periodically commands it to adjust its timing in a like manner. The user station transmits a control preamble at the start of each time slot to allow the base station to perform round trip timing calculations and adjustment of the user station's power or antenna selection.

Patent CA-2237283-A1 (CA)
Title: Capillary carpet irrigation system
Inventor: CARON JEAN
IPC: A01G27/04
Filed: 1998-05-08
Abstract: The invention relates to a capillary carpet irrigation system which includes a water bearing capillary carpet disposed on a supporting surface and a plurality of water  permeable  pots  resting  upon  and  in  hydraulic connection with the carpet.   The pots contain growing medium and roots of plants.   Conventional irrigation equipment supplies water to the carpet.   A four layer capillary  carpet  includes:  a water  impermeable  base membrane  of  polyethylene;   and  a  water  permeable microperforated dark coloured top membrane. Between the top and base membranes two water bearing capillary mats  are  supplied  with  water  from  the  irrigation equipment.   The base membrane prevents water seepage into   the   underlying   soil    substrate.       The microperforated top membrane permits passage of water into the carpet while inhibiting evaporation and weed growth.  The dark colour also inhibits algae growth in the  mats.    The  fine  pore  rigid  capillary  mat  is disposed  upon  the  base  membrane  and  is  capable  of receiving water  from the  irrigation equipment.    The rigid mat is relatively stiff and can retain a selected hydraulic transmissivity while supporting the weight of the pots.   A resilient coarse pore capillary mat is disposed  upon  the  rigid  mat  and  beneath  the  top membrane.     The  compressible  mat   is   resiliently compressible  locally under each pot thus  defining  a plurality  of  localized  capillary  action  conduits between  the  rigid mat  and each water  permeable pot through  the  permeable  top  membrane.    The  resilient coarse mat when uncompressed has a negligible capillary rise and serves to inhibit evaporative water loss from the  underlying  rigid  mat.     The  pores   of  the compressible  mat  impede  air  circulation  immediately above the upper  surface of water held in the water bearing rigid mat.  The air within the compressible mat pores immediately above the rigid mat therefore have a high humidity.  Air circulation within the compressible mat is impeded by the inherent resistance of the porous structure.  Thus, water vapour escape from the water surface in the rigid mat through the perforations of the top membrane is impeded reducing evaporative water loss.  To impede root growth from the pots into the top membrane and porous mats, a root growth biobarrier is disposed within each pot.

Abstract: Apparatus, kit and method for painting a marbleized pattern on an essentially flat interior surface using paints with a plurality of colors. Before beginning the process, if necessary, the surface is cleaned and prepared This can include applying masking tape around the periphery of the area to be painted. Splotches of paint of one color are then applied to a portion of the total area to be painted using a stiff bristled brush. Splotches of other paint colors are then applied interspersed with the previous colors, The brush is then used to preliminarily blend the various splotches of paint. A special blending tool faced with wool is used to complete blending the paint. The wool face is moistened before use, end blending is completed by patting the paint with the wool face of the tool while changing the angles and locations of the tool between each contact. Accent veining lines can be added to the blended paint surface using a feather dipped into a paint of a different color than the blended surface.
