Title: Crayon moulding kit and method of making
Inventor: FROMM WAYNE G
IPC: B43K7/00
Filed: 1996-01-29
Abstract: A method and apparatus for molding crayons of novel shapes.  The apparatus includes a one or more two-part mold assemblies, and one or more crayon bars.  When the two-part mold is closed it defines a mold cavity having a volume approximately equal to the volume of the crayon bar.  The crayon bar is formed from a wax-like material, such as paraffin or beeswax, to which a non-toxic pigment has been added, which pigment will drop when the crayon bar is rubber across paper or the like.  The wax-like material is selected to be deformable when heated to a temperature range between body temperature and an upper temperature below that of scalding water.  In use the crayon bar will be heated to its deformable temperature, placed in a mold, the mold then being closed and pressure being applied to cause the crayon bar to deform to the shape of the mold cavity.  In order to facilitate pressure being applied the kit also includes press means, and may include a reservoir in which the crayon bar may be heated.
Patent CA-2168468-A1 (CA)
Inventor: FROESCHKE REINHARD
IPC: B01J2/20
Filed: 1995-05-23
Abstract: Dans les systèmes rotatifs connus de formation de gouttes, munis d'un guide, ce dernier est centré par l'intermédiaire d'une fixation, avec un mandrin, au niveau d'une cavité ménagée à l'extrémité libre du tambour fixe, ce qui est très complexe. Il est prévu que le tambour fixe dépasse du tambour rotatif, au niveau de son extrémité libre et que le bras pivotant du guide soit protégé à l'aide d'une bague entourant cette extrémité cylindrique et d'un dispositif d'accouplement. Cette mesure permet également des déplacements longitudinaux dus aux dilatations thermiques. Ce dispositif s'utilise dans des systèmes rotatifs servant à transformer des matières fondues en gouttes.

Title: Broadband communications system
Inventor: THOMPSON LEO J
IPC: H04N7/173
Filed: 1994-09-19
Abstract: A broadband communications system hav-ing means for coupling telephony (10) or other digital networks to a CTV network (12). The sys-tem includes transmitting a multiplex of telephony signals in 3 MHz channels in the forward band of the CTV network. Each 3 MHz channel is QPR modulated on a carrier and contains multiple sub-scriber telephony signals. The forward telephony channels are demodulated and demultiplexed by a plurality of subscriber terminals into the indi-vidual telephony signals directed to an addressed subscriber. The individually addressed telephony signal is then applied to a line card which con-nects the subscriber telephony equipment to the system. Audio and control signals returning from the subscriber are digitized into standard tele-phony signals and modulated on a carrier in 50 kHz reserved telephony channels onto the reverse band of the CTV network. The multiplicity of reverse band telephony channels are demodulated and multiplexed into a standard telephony signal which can be directly interfaced to the telephony network.

Patent CA-2180680-A1 (CA)
Title: Skimming device
Inventor: LESSARD MICHEL
IPC: B22D43/00
Filed: 1996-07-08
Abstract: A skimming device for skimming debris floating on the surface of a volume of liquid. The skimming device includes a pair of jaw members pivotable relatively to one another. Each jaw member has a base wall defining a free peripheral edge and a walled peripheral edge. A peripheral wall extends upwardly from the walled peripheral edge. The jaw members are adapted to pivot between a jaw open configuration wherein the peripheral walls are in abutting contact with one another and a jaw closed position wherein the free peripheral edges of the jaw members are in an abutting relationship relatively to one other and the jaw members form an open top container. The base wall free edge is thus adapted to skim the top surface of the liquid as the jaw members move between the jaw member open configuration and the jaw member closed configuration. A deflecting plate is mounted underneath each base wall. The deflecting plates are angled so as to bias the floating debris towards the base wall free edge as the jaw members are lowered in contact with the volume of water and as the jaw members pivot towards their closed configuration.  The jaw members are pivotally mounted on a spacing arm. The spacing arm is pivotally mounted on a base member. A stabilizing device is provided for presenting tilting of the jaw members as the spacing arm is pivoted relatively to the base member. The spacing arm is also mounted so as to be rotatable about the base member. In a second embodiment, the spacing arm is also telescopic so as to allow positioning of the jaw members over the top surface of the volume of liquid.
Patent CA-2184729-A1 (CA)
Title: Regulation of pyrocarbon coating
Inventor: EMKEN MICHAEL R
IPC: B01J8/24
Filed: 1995-03-03
Abstract: Deposition of a pyrocarbon coating of precise thickness onto one or more substrates being levitated along with a bed of particles in a fluidized bed coating enclosure is accomplished by varying the amount of hydrocarbon supplied to the bed as a part of an upward levitating flow to compensate for changes which are detected in the size of the fluidized bed. Increases and decreases in the size of the bed are detected by monitoring either the differential pressure above and below the bed or the weight of the bed, and compensating changes are made to return the bed to its desired size by changing the flow rate of hydrocarbon. For example, when a growth in bed size is detected that is not attributable to an aberration in either particle supply or withdrawal, the amount of hydrocarbon being supplied to the bed is decreased so as to cause the size of the bed to gradually return to its desired value.

Title: Multi-layer blown-film extrusion die
Inventor: BENTIVOGLIO ALFREDO
IPC: B29C48/10
Filed: 1997-02-20
Abstract: This invention relates to a Multi-Layer Blown-Film Extrusion Die. An Extrusion Die is a key component of extrusion equipment, used in manufacture of Blown film for packaging industry. Although this Extrusion Die relates to production of five or more layers of blown films, it can also be used for production of lesser number of layers. While in the conventional outside fed die, melt was to be conveyed around the die in a fanning-out configuration, in this invention the polymer melt is split into two streams, before being fanned or spread around the circumference. Polymer melt enters several spiral or helical grooves prior to joining the gap that enjoins melt with other layers of the melt streams. The dimensions of spiral grooves and lands are carefully calculated, keeping in view relevant factors such as melt viscosity, shear sensitivity temperature and pressure requirements etc.
