Patent CA-2222666-A1 (CA)
Title: Optical sampling by modulating a pulse train
Inventor: HADJIFOTIOU ANAGNOSTIS
IPC: G02F1/35
Filed: 1997-11-26
Abstract: An interferometer, such as a Mach-Zehnder type is fed with a pulse train. One arm is fed with a data stream, so as to modulate the pulse train according to the data stream. This enables the data stream to be regenerated, or sampled without converting from optical form into electrical form. Thus all optical regeneration, multiplexing, demultiplexing or retiming to remove jitter, can be achieved. An optical amplifier (20) in one arm of the interferometer enables the interference condition of the interferometer to be varied, to cause the pulse train to be modulated by the data.

Abstract: A one piece, rectangular shaped, non ferrous sheet metal device, bent upward to form a perpendicular step tread, positioned and permanently fastened to a raised structure's pitched roof deck.. This device is a readily available foot or hand hold to safely support a person when they access; move on and about; or exit a roof's surface from a ladder, scaffold or bucket lift. When more than one of these step devices are installed and strategically spaced horizontally, vertically or diagonally about the roof's surface they form a secure, permanent ladder type system which can be used for routine maintenance tasks or emergency situations. The long tongue above the step tread has a minimum of five, widely spaced, "X" pattern holes about its surface for insertion of the stainless steel screws that permanently fasten the device to the roof's deck.  This same tongue is. installed between two courses of roofing material in "shake" type fashion whether it be cedar shakes, interlocking duroid, asphalt, vinyl, fiberglass shingles, ferrous or non-ferrous metal sheeting.

Patent CA-2239841-A1 (CA)
Inventor: DESHPANDE RAJENDRA D
IPC: D21F3/02
Filed: 1998-06-08
Abstract: A press of the Beloit Extended Nip® type has a nip defined between a backing roll and an elongate shoe. A paper web travels on a dryer felt through the nip and is supported over the shoe by a bearing blanket. The shoe has a rigid concave core to which is fixed a layer of compliant material which defines a concave surface. Lubricant is introduced between the compliant material and the bearing blanket to form a hydrodynamic fluid film. Preferably the rigidity of the compliant material is of the same or lesser order of magnitude than the rigidity of the fluid film at the center of the shoe in the machine direction, such that the fluid film at the nip causes a depression in the compliant material which is filled with lubricant. The thickness of the lubricant is thus greater at the center of the shoe than at regions outward from the shoe center and the escape of lubricant from the shoe is retarded. The compliant material comprises an elastomer with a low coefficient of friction and high abrasion resistance. It has the ability to deform with increased pressure upon it, thus allowing a paper wad or web deformity to pass through the nip without damage to the bearing blanket.      Alternatively, the compliant layer may define a plurality of lubricant pockets.

Title: Magnetic stretching of magnetized neurons for spinal cord or peripheral nerve repair and regeneration
Inventor: HALPERN ALAN A
IPC: A61N2/00
Filed: 1999-05-21
Abstract: A severed or otherwise interrupted spinal cord or peripheral nerve is provided with metallic nanoparticles which are absorbed or actively incorporated into the neurons and their axons. The severed or otherwise interrupted nerve or cord is then exposed to an external magnetic field which is moved longitudinally of the severed or otherwise interrupted nerve or spinal cord, thereby stretching the magnetic particle-loaded neurons and their axons along the desired axis for bridging the gap or gaps and repairing the injured spinal cord or nerve. The procedure may be repeated to extend the area of repair.      The severed or otherwise interrupted spinal cord or peripheral nerve is advantageously provided, either internally or alongside, with an insert comprising multiple strands of biodegradable material having metallic particles oriented along the axis thereof, for focusing and concentrating the external magnetic field in the desired axis.      Magnetic particles tagged with substances which are biologically incorporated into neurons and their axons may be employed to increase the absorption of the magnetic particles into the cells and/or to stimulate the growth activities of the cell.
