Title: Wear indicator for a disposable razor
Inventor: DOROODIAN-SHOJA SIAMAK
IPC: B26B21/40
Filed: 1995-01-17
Abstract: A wear indicator (20) is located on the head or frame (14) of a disposable razor or razor cartridge (10), in close proximity to the shaving edge (18) of the blade (16).  The wear indicator comprises a mass of material that gradually wears away as the disposable razor or cartridge is used in shaving, the amount of material wearing away being correlated with the amount of wear on the blade edge to provide a visual indication of the relative wear on the blade.  Preferably, the wear indicator comprises two strips of material, one atop the other, the upper strip wearing away to reveal the contrastingly-colored lower strip.  Alternatively, the material may wear away to reveal or indicia or lettering on the lower strip.

Title: System for simplifying the implementation of specified functions
Inventor: DOMANIK RICHARD A
IPC: G06F3/033
Filed: 1996-09-13
Abstract: A machine, method and medium for implementing functions using an input device in a manner that enhances efficient operation of a mechanism capable of operating in at least two states. The functions are implemented via a convenient input device, such as a mouse. One or more specified actuators of the input device implement a given function when the mechanism is in a first state, while at least one of those actuators implements a different function when the mechanism is in a second state. In embodiments of the present invention contemplating that the mechanism is a microscope system, two states in which the microscope system is envisioned to operate are a scan state and a pause state. The scan state allows the microscope system to execute a pre-defined scan sequence, while the pause state allows the microscope system to pause from that sequence.

Title: Method for mitigating residual stresses in welded metal components using high torch travel speeds
Inventor: OFFER HENRY PETER
IPC: B23K9/02
Filed: 1995-04-19
Abstract: A process for providing a significant improvement in the detrimental tensile residual stress condition on the root side of welds, especially on the inside wall of piping welds. The method uses a high welding torch travel speed (10 inches/min), especially on the last one or two cap passes. The process relies on the limited thermal heat sink capability of the pipe wall and nearly completed weld joint itself to generate a significant through-wall temperature gradient, and therefore a sufficient through-wall stress gradient during the welding. This stress gradient results in metal plasticity and permanent strains, and therefore a reduction in the magnitude of the final residual stress or, preferably as conditions allow, a reversal in the direction of the stresses from tensile to compressive. The method can be used as a welding process or as a heat treatment. In the case of heat treatment, the far surface of the weld joint is heated without fusion of the material making up the far surface.

Patent CA-2187926-A1 (CA)
Title: Method and system for routing packets in a packet communication network using locally constructed routine tables
Inventor: FLAMMER GEORGE H III
IPC: H04L12/56
Filed: 1995-04-11
Abstract: In a packet communication system, wherein nodes are assigned an absolute coordinate-based address and muting decisions are made at each node (S2, S7) without the use of directory-based routing, routing decisions made for a particular packet with an ultimate destination are stored at each node so that the next packet sent by that node to that same ultimate destination can be forwarded in accordance with the previous routing decision made for that destination. Routing decisions are stored locally at each node in a routing table (S6, S12). In one embodiment, nodes also store routing information about the source node for a packet so that when a return packet is received for the original source, the relay node will not have to make a routing decision.
Patent CA-2188076-A1 (CA)
Inventor: ROSS MICHAEL RAY
IPC: H04L7/00
Filed: 1996-10-17
Abstract: Synchronizing wireless base stations by reception of a synchronization signal that is transmitted in an unused B channel of an ISDN link interconnecting a switching network and the base stations. The synchronization signals are generated by the tone circuit of the switching network which advantageously is a digital signalling processor (DSP). Each base station is interconnected to the switchingnetwork via two basic rate interface (BRI) links. Each base station can handle amaximum of three wireless handsets thus leaving one of the four B channels present in the two BRI links unused. It is this unused link that is utilized to transmit the synchronization signals from the switching network to the base stations. Furthermore, the switching network is configured in such a manner that all base stations receive the synchronization signals at the same time over the unused B channels.

Patent CA-2196346-A1 (CA)
Inventor: BAKER ALBERT D
IPC: H04Q11/04
Filed: 1997-01-30
Abstract: Provisioning a Central Office (CO) Basic Rate Interface (BRI) access is a complex procedure which involves hundreds, and potentially thousands, of parameters that must be asserted to configure the CO for a particular user's service profile. In such a complex procedure, errors in the provisioning may be introduced which are difficult and costly to detect and correct. To solve this problem, a provisioning tool which exercises BRI lines i.e., digital subscriber lines (DSLs) from a CO to a premises switch is defined which validates that transport related restrictions and permissions are properly administered at the CO. This is achieved by the system calling itself over such lines, and varying the types (e.g., voice, digital, data, 3.1 kHz audio, et al.) of call attempts that are placed to ensure that all lines support the intended services.

Patent CA-2202582-A1 (CA)
Inventor: ZOLLIKER PETER
IPC: H04N1/00
Filed: 1997-04-14
Abstract: A method for producing copies of photographic originals, wherein an original is scanned regionally. With the aid of measurement data thus obtained, a decision is made in a test step, on the basis of specified criteria, whether the original is worth copying or not. On the basis of this decision, the particular original is or is not copied onto photographic copy material. In the test step, the scanned original is assigned to at least one of at least three categories oforiginals; namely a first category which includes originals that are unequivocally worth copying, a second category which includes originals that are unequivocally not worth copying, or a third category which includes originals that are neither unequivocally worth copying nor unequivocally not worth copying. Both originals assigned to the first category and originals assigned tothe third category are copied onto photographic copy material, and the copies oforiginals assigned to the third category are specifically identified as belonging to that category and are not included in calculating the price for processing the customer's order.

Title: Ultra-sensitive detection of contaminants in gas via intracavity laser spectroscopy (ils)
Inventor: KALISKY YEHOSHUA
IPC: G01N21/35
Filed: 1996-08-29
Abstract: Contaminants in gases such as corrosives are detected optically at concentrations below 1 part-per-million (ppm) and extending to a level below 1 part-per-trillion (ppb) by using intracavity laser spectroscopy (ILS) techniques. A laser (500), the ILS laser (500), is employed as a detector (10). The ILS laser (500) comprises a gain medium (507) contained in a laser cavity (5). A gas sample containing gaseous contaminant species is contained within a gas sample cell (406) which is placed inside the laser cavity (5) and on one side of the gain medium (406). In the case where gaseous species are to be detected in corrosive gas, the corrosive gas is prevented from reacting with the components of the ILS laser (500). The output signal from the ILS laser (500) is detected and analyzed to identify the gaseous species (via its spectral signature). The concentration of the gaseous species can be determined from the spectral signature as well.
