Patent CA-2402204-A1 (CA)
Inventor: BARTH GEORG MARTIN
IPC: D04H3/11
Filed: 2000-04-18
Abstract: A plurality of substantially parallel continuous filaments, e.g. of cellulose acetate or rayon, and preferably newly formed, are consolidated or partially stabilized, e.g. by application of solvent and pressure, by hydroentanglement, by embossing, or by crimping and stretching. The filament assembly or subassemblies thus produced are further stabilized by folding, bundling, twisting or intertwining, e.g. to form braids ( 10 ), and are then bonded to a carrier layer or sandwiched between outer layers ( 12, 14 ), e.g. by hydroentanglement, melt blowing, spinbonding etc. The stabilized filament assemblies may be arranged spaced transversely and may be cut just prior to bonding so as also to provide longitudinally spaced three dimensionally thicker regions, ready for conversion to finished products such as absorbant feminine hygiene products or medical swabs or the like.

Title: Flow-through ammonia photodissociation device
Inventor: SUNATORI GO SIMON
IPC: B01J19/24
Filed: 2002-09-27
Abstract: ~ An ammonia photodissociation device comprises a flow-through fluid channel, a porous membrane, a catalyst, and an ultraviolet light source. The flow-through fluid channel has an inlet port for inflow of gaseous ammonia (NH3), and an outlet port for outflow of a mixture of gaseous nitrogen (N2) and gaseous hydrogen (H2). The porous membrane separates the flow-through fluid channel into a first chamber and a second chamber. The catalyst is disposed on the porous membrane in order to increase the rate of chemical reactions. The ultraviolet light source generates electromagnetic radiation in the ultraviolet (UV) region of the spectrum, and is capable of dissociating gaseous ammonia (NH3) into a mixture of gaseous nitrogen (N2) and gaseous hydrogen (H2) according to formula: 2 NH3 -> N2 + 3 H2. This invention relates to photodissociation devices, and the principal use of the invention is for hydrogen generators.

The first portion is arranged to receive the second portion and at least partially defines a flowline receiving aperture. The first and second portions (5,8) together form a magnetic circuit around the aperture and the second portion carries a winding (9) arranged for electrical connection to the communications unit (4).  The winding links with the magnetic circuit when the second portion (8) is received in the first (5) such that an alternating current in the winding will generate a corresponding current in a flowline disposed in the aperture and vice versa. The arrangement allows the first portion to be permanently mounted on a flowline and the second portion to be inserted in situ.
Patent CA-2433049-A1 (CA)
Inventor: HILL MICHAEL R S
IPC: A61B5/0215
Filed: 2001-12-27
Abstract: An implantable stimulator and monitor measures a group of heart failure parameters indicative of the state of heart failure employing EGM signals, measures of blood pressure including absolute pressure P, developed pressure (DP=systolic P - diastolic P), and/or dP/dt, and measures of heart chamber volume (V) over one or more cardiac cycles. These parameters include: (1) relaxation or contraction time constant tau ($(mc)$(mc)); (2) mechanical restitution (MR), i.e., the mechanical response of a heart chamber to premature stimuli applied to the heart chamber; (3) recirculation fraction (RF), i.e., the rate of decay of PESP effects over a series of heart cycles;  and (4) end systolic elastance (EES), i.e., the ratios of end systolic blood pressure P to volume V. These heart failure parameters are determined periodically regardless of patient posture and activity level. However, certain of the parameters are only measured or certain of the data are only stored when the patient heart rate is regular and within a normal sinus range between programmed lower and upper heart rates. The parameter data is associated with a date and time stamp and with other patient data, e.g., patient activity level, and the associated parameter data is stored in IMD  memory for retrieval at a later date employing conventional telemetry systems.  Incremental changes in the parameter data over time, taking any associated time of day and patient data into account, provide a measure of the degree of change in the heart failure state of the heart.

Title: Method of applying marking agent to aluminum sheet for scrap sorting purposes
Inventor: COURVAL GREG J
IPC: C22B1/00
Filed: 2002-03-26
Abstract: Application of a marking agent to metal stock, such as aluminum sheet, during and as a part of procedures for preparing the sheet for subsequent, scrap-generating manufacturing operations, to provide a detectable mark on pieces of manufacturing scrap derived from the marked sheet and commingled with scrap of other aluminum alloy sheet, so that the scrap can be sorted and the marked alloy scrap pieces separated from scrap of other alloy sheet to which the marking agent was not applied. Different marking agents, providing detectably different marks, may be respectively applied to sheet of different compositions if scrap pieces of more than two different compositions or compositional families are to be sorted and separated from each other. The marking agent may be added to a lubricant or prelubricant conventionally applied to the sheet by the sheet producer prior to delivery to the manufacturing customer. If an indelible marking is applied selectively only to areas of the sheet stock that will be scrapped, it can be safely retained throughout the manufacturing operation without affecting the final produced article.
