Patent CA-2228649-A1 (CA)
Inventor: METTES JACOB
IPC: G01N27/42
Filed: 1996-08-01
Abstract: A new design for and an improved process of manufacturing a detecting unit (12) for a type I electrolytic cell (10) with thin film electrodes. In the first step of the process, a long, narrow, transparent, hollow glass tube (98) is provided having an inside surface, an outside surface, and an end with a rim. A thin, noble metal film (120) is deposited on the inside surface of the hollow glass tube. Then, a beam (130) from a light source (140) is directed through the hollow glass tube to remove a first portion of the noble metal film from the inside surface of the hollow glass tube and create a first spacer area (122). The beam also removes a second portion of the noble metal film from the inside surface of the hollow glass tube and creates a second spacer area. Consequently, two, separate electrode wires (46, 48) are created.  Finally, an hygroscopic film is deposited on the entire inside surface of the hollow glass tube, covering completely the first and second electrode wires, and the spacer areas.

Abstract: A down hole running tool (14) travels in a first direction through a drill pipe for installing bit segments (18) at the end of a drive sub (12) attached to the drill pipe. The tool (14) includes a first portion (82) and a second portion (84) which is retractably coupled to a leading end of the first portion (82). The first portion (82) includes a tubular extension (134) which receives a spigot (136) that extends from an upper end of the second portion (84). A pin (138) extends transversely through the tubular extension (134) and resides within opposing slots (140) formed in the spigot (136). There is a stepped reduction in the internal diameter at the lower end of the tubular extension (134) so as to form a cup-like structure (146). A spring (168) is disposed about the spigot (136) and has an upper end seated in the cup-like structure (146) and a lower end bearing against an upper face (170) of the second portion (84). The spring (168) is biased so as to push the first and second portions (82 and 84) apart in the longitudinal direction. When the tool (14) is lowered into the drive sub (12) and the second portion (84) hits a stop, the first portion (82) is able to continue movement for a short distance against the bias of the spring (168) by virtue of a gap existing between the surface (170) and the end of the cup-like structure (146).

Abstract: An electric open-top melter for use in the manufacture of mineral fibers, such as fiberglass, is provided with a side-discharge outlet.  The side-discharge outlet allows the melter, conditioner/refiner, and forehearth to all be located on substantially the same level, thereby allowing molten glass to flow from the side of the melter, through the conditioning zone, and into the forehearth from which spinners produce glass fibers or the like.  Isolation members are provided in the conditioning or refining area so as to enable molten glass therein to be isolated from the melter and forehearth when the molten glass level is lowered below the tops the isolation members.
Patent CA-2246078-A1 (CA)
Inventor: CHMIEL STEVEN F
IPC: H02P3/04
Filed: 1998-09-28
Abstract: A control circuit (10) is provided for an electric motor brake (12) having an electromagnetic brake coil (14) energizable to actuate the brake to a released condition permitting rotation of an electric motor (16), and de-energizable to enable actuation of the brake setting the brake to a braking condition stopping rotation of the motor. The control circuit includes a switch (102) having an on state energizing the brake coil, and an off state de-energizing the brake coil. A discriminating trigger circuit (76 et al) responds to voltage across the motor to trigger the switch between its on and off states, and discriminates between increasing and decreasing motor voltage during energization and de-energization, respectively, of the motor, to trigger the switch to its on state at a first motor voltage, and to trigger the switch to its off state at a second motor voltage higher than the first motor voltage, to compensate for voltage generated by continuing inertia-rotation of the motor following de-energization thereof otherwise delaying actuation of the brake. The triggering of the switch to its off state at the second motor voltage enables faster application of the brake and stopping of the motor. The same switch both energizes and de-energizes the brake coil, without a separate relay for de-energizing the brake coil.

Abstract: Mineral fibre additives for enhancing the properties of bitumen are disclosed. A mineral fibre additive for fluxed bitumen is provided wherein the fibres are agglomerated into nodules before being added to the bitumen, and the additive comprises a water- and heat-stable binder previously treated with a wetting agent for wetting the fibres with the bitumen. The water- and heat-stable binder preferably consists of phenolic resins of the kind usually used in insulating fibre mats made of either glass wool or rock wool. Similarly, the wetting agent advantageously consists of silicone resins. A method is also provided for producing said additive. According to the method, (a) fibres are taken from a bonded mineral fibre mat such as an insulating mat, (b) a resin acting as a wetting agent for the bitumen is sprayed onto the fibres, and (c) the fibres are treated in a noduliser. Step (b) may be carried out before or after step (c). The use of insulating mineral fibre mats has numerous advantages. Indeed, the problem of recycling industrial products is causing growing concern and finding a use for insulating fibre panels to be recycled is highly important.
