Title: Mobile multi-printer station printing barcode labels and signs
Inventor: JOHNSON KELLY L
IPC: G06F3/12
Filed: 1996-06-11
Abstract: A mobile multi-printer station communicates with a remote host station via radio frequency messages. The multi-printer station includes a number of different types of printers for printing on different types and sizes of record members such as labels, tags and signs. Each of the printers is supported on a cart for mobility. The cart also supports a radio frequency communicator for receiving and transmitting radio frequency printer messages to and from the host station. The radio frequency communicator couples received printer messages to each of the printers on the cart. Each of the printers includes a memory for storing a printer address and a processor that is responsive to the received digital information identifying a printer for comparing the information to the stored printer address and the printer processor processing digital data in response to a match between the stored printer address and the received digital information. Communication parameters may be programmed into a printer on the cart by multiple actuations of a single key to provide a very simple procedure for setting communication parameters.

Title: Floating myocardial electrode for implantable pulse generator
Inventor: STOKES KENNETH B
IPC: A61N1/05
Filed: 1994-12-19
Abstract: An implantable lead (10) for establishing electrical contact between a medical device and body tissue, in which an active fixation mechanism (18) secures the lead (10) in place while allowing a distal electrode (14) on the lead to mechanically "float" with respect to the body tissue. In one embodiment, the active fixation mechanism (18) comprises a curved hook disposed on the lead (10) at a point spaced proximally back from the distal end (14) of the lead (10). The curved hook (18) defines a helix around at least a portion of the lead's circumference.  A hollow introducer needle is slidably disposed on the lead (10). The hollow needle is provided with a longitudinal slit in a distal section of its length, such that the distal section of the needle can be advanced over the distal end (14) the lead (10), past the fixation hook, which is received in the longitudinal slit. With the needle slid over the distal end (14) of the lead (10), the needle is stabbed angentially into an implant site, bringing the fixation hook (18) proximal to the surface of the body tissue. Then, the needle is twisted (bringing about a twisting of the lead (10)), causing the curved fixation hook (18) to pierce and engage the body tissue, securing the lead (10) in place. Then the needle is withdrawn from the body tissue and removed from the lead (10). In an alternative embodiment, the lead (10) can be placed by an endocardial approach using a flexible cannula with a longitudinally slotted tip.

IPC: C07C29/156
Filed: 1995-02-28
Abstract: Stabilisation of a reduced cop-per catalyst by a) passivating the cat-alyst by passing a gas stream that is free of reducing gases and which contains 0.05 to 0.5 % by volume of oxygen and an amount of carbon dioxide at least twice the amount of oxygen through a bed of the cata-lyst until the catalyst is passivated, the proportion of oxygen in said gas stream and the temperature at which it is fed to the bed being such that the temperature of the catalyst does not rise to above 100°C during said pas-sivation step, and then b) increasing the oxygen content of the gas pass-ing through the bed until the oxygen partial pressure corresponds to that of air at atmospheric pressure. The process may be applied to the stabil-isation of fresh reduced catalysts or to the stabilisation of used, e.g. spent catalysts, before discharge thereof from a reactor.

Patent CA-2190339-A1 (CA)
Inventor: BOWLIN WILLIAM P
IPC: B27B31/06
Filed: 1996-11-14
Abstract: A saw carriage or module for manually, semiautomatically or automatically cutting stems typically supplied by a stem handling apparatus,  which  stem handling apparatus delivers  full-sized, substantially tree-length stems to one or more of the saw carriages for cutting into logs, poles or other segments.  During automatic operation of the module(s)  stems are typically scanned by an optical device and the physical characteristics of the scanned stem are sent to a computer, which selects the cutting pattern and transfers this information to a programmable logic controller.  The programmable logic controller typically orchestrates positioning of one or more linearly-adjustable saw carriages or modules and on-board carriage saw blades to optimize cutting of the stems into the segments.  After the modules and saws are so positioned, each stem is sequentially transferred by the handling apparatus to the saw modules, where it is positioned, clamped and cut into multiple segments at the preselected optimum points.  Stem segments are ejected from the saw carriages or modules by ejecting devices provided on each module.
