Title: Spiral binding method and apparatus
Inventor: STILES WILLIAM P
IPC: B42B5/10
Filed: 1995-10-11
Abstract: An apparatus (10) for spiral binding a stack of papers (24) together as a unit. The apparatus includes a punch (12) for punching a plurality of holes (23) along one edge of the stack of papers and a spiral binding unit (14) for feeding a spiral coil (36) into the holes. The spiral binding unit (14) includes an aperture (44) through which a coil is inserted between a shoe (74) and a rotatably mounted roller (72). As the coil (36) is inserted, the shoe (74) pushes the coil into contact with the roller (72). As the roller (72) rotates, the coil (36) is guided through a series of slots (86) which cause the coil to spiral into the holes in the stack of paper. The punch (12) includes a ramp (186) that presses a series of punch pins (188) through the stack of papers. The ramp (186) includes a plurality of steps (222) that incline upwarldy on either side of a center step (224). The punch first punches holes in the center of the stack of papers and then punches holes outward from either side of the center. The apparatus includes indicators (38) that provide an operator with an indication of appropriate size of spiral coil to use, and an indication of when a wastebasket (52) holding the wastepaper requires emptying.
Patent CA-2205539-A1 (CA)
Inventor: KERSHAW STANLEY S
IPC: H01F27/04
Filed: 1989-12-01
Abstract: Testing of a transformer in an oil filled housing is done by providing an external arrester insulator/isolator penetrating and making an electrical connection through the housing while preventing leaking of oil from said housing.  An arrester inside said housing is electrically coupled between an interior end of arrester isolator and a predetermined potential point within the housing.  An exterior end of said arrester isolator is removably and electrically coupled to a ground potential point.  The ground coupling is removed from the exterior end of the arrester isolator and the transformer is tested by measuring electrical characteristics on transformer connections emerging from the housing.  The ground coupling is reconnected to the exterior end of the arrester isolator after testing is completed.  If required, an insulating cap may be applied to the external isolator to provide additional withstand capability to external flashover during the tests.

Abstract: A liquid discharging method comprises the step of displacing the free end of the movable member following the creation of air bubble in the air bubble generating area.  For this method, the fulcrum of the movable member is positioned on the side different from liquid discharging side with respect to the displacement area for the free end of the movable member to be displaceable, and at the same time, the free end thereof is arranged to face the effective bubbling area positioned on the downstream side of the central portion of the length of the effective bubbling area that forms the bubble generating area in the direction of the movable member from the fulcrum to the free end thereof, and a part of the effective bubbling area positioned to face the free end of the movable member on the downstream side of the effective bubbling area is arranged to face the displacement area directly.          Thus, the initiation of the displacement of the free end of the movable member is effectuated quickly and reliably, and the pressure exerted by the air bubble creation is led to the discharge port side and the fulcrum side of the movable member sufficiently at the time of bubbling, and the development of air bubble that follows is directed to the discharge port side more reliably and efficiently.

Patent CA-2229273-A1 (CA)
Title: Polymer segregation process
Inventor: JOSEPH SIBICHEN
IPC: B29C48/05
Filed: 1998-02-10
Abstract: The present invention provides a method enabling segregation of the various ingredients making up the polymer based products into component product streams and collection of these component streams so as to form individual product streams. Thus, according to this invention there is provided a process for purposefully segregating polymer-polymer and polymer-additive mixtures. The process for segregating the various combinations of components may be advantageously used on the one hand for the production of separate product streams from a mixture of polymers or polymer-additives in, for example, recycling of waste plastic based products, or on the other hand, in the production of polymer-polymer or polymer-additive layered structures exhibiting preselected spatial segregation of the various components. In its simplest form, the polymer segregation part of the process consists of a tube added to an extruder. During segregation, polymer layers containing different blend compositions are formed. Operating conditions are selected to enhance differences in viscosity between polymer components. This includes addition of low viscosity grades of one of the polymer components present to encourage migration of that component to the high shear region of the flow. Segregation may occur in either the extruder or in a tube added onto the end of the extruder, or in both. Preferential segregation of additives into one or more of the polymer layers can also be effected. Addition of components which attract the additives to be segregated provide a method of segregating a wide variety of additives.
Patent CA-2229302-A1 (CA)
Inventor: SCOBEY MICHAEL A
IPC: G02B6/293
Filed: 1998-02-12
Abstract: An optical multiplexing device demultiplexes collimated light from a fiber-opticsource into separate individual wavelength sub-ranges or channels, and/or multiplexes separate channels to a common fiber-optic waveguide or other destination. An optical block defines an optical gap between two parallel surfaces having an optical port on a first such parallel surface for passing the multi-channel collimated light into the optical gap. A channel port and at least one other reflective element, e.g., multiple channel ports arrayed in spaced relation to each other, are secured to the optical block at the parallel surfaces, providing an unobstructed, epoxy-free multi-point light path within the optical gap. At each channel port an interference filter secured to the optical block spans the optical gap. Each filter transmits a wavelength sub-range of the multi-channel collimated light passed by the optical port, and reflects other wavelengths. Thus, a wavelength sub-range of the multi-channel light passed through the optical gap to a first channel port, which is in-band of that first channel port, is transmitted through that first channel port. Light not transmitted through that first channel port is reflected back through the optical gap, e.g., to strike a second channel port, at which a second, different wavelength sub-range is transmitted. The reflected optical signal thuscascades in a "multiple-bounce" sequence through the optical gap of the multiplexing device, sequentially adding and/or removing channels.
