Patent CA-2151800-A1 (CA)
Inventor: VAN ALLMAN DON T
IPC: F16B19/14
Filed: 1995-06-14
Abstract: A steel pin is disclosed of a type to be forcibly driven into a steel substrate via a powder-actuated tool.  The steel pin has a substantially cylindrical shank and a substantially sharp point, which extends from one end of the substantially cylindrical shank, which conforms substantially to a tangent or secant ogive except for a substantially spherical tip having a radius in a range of about 0.015 inch (about 3.75 millimeters 3 to about 0.03 inch (about 7.5 millimeters), which has substantially true concentricity, which has surface-texture irregularities with a roughness-height index value not greater than about 30 microinches (about 0.76 micrometers), and which appears to be substantially free of other surface imperfections when viewed under 60x magnification. Optimally, the ogive is a tangent ogive with an ogive radius about ten times the shank diameter and with an ogive length about twice the shank diameter, and the tip radius is about 0.1 times the shank diameter.  The substantially cylindrical shank is joined to the substantially sharp point at a transition having a substantially smooth, continuously curved surface, and is knurled near the transition.  The steel pin is made by deforming a length of steel wire, as by forging or swaging, so as to form the steel pin with the substantially cylindrical shank and with the substantially sharp point and reshaping the substantially pointed end, as by barrel finishing.

Title: Anode material and method of manufacturing the same
Inventor: IMOTO HIROSHI
IPC: H01M4/38
Filed: 1993-12-28
Abstract: A material for a cathode is made of a carbon material hard to turn to graphite and obtainable by burning a carbon precursor. For this carbon material having the graphitization resistance, the weight % Ps of carbon in the material is smaller than 0.59 or the stacking index SI is smaller than 0.76. This carbon has a structure of stacked layers, which is determined by the diffraction peak due to the (002) plane of the crystal lattice, and the X-ray diffraction spectrum on the side of an angle lower than the diffraction peak among the Xray diffraction spectrum. The average Nave of the number of stacked layers is smaller than 2.46. Alternatively, letting the burning temperature be T ~C, and the half-width of a peak appearing near 1,340 cm-1 in the Raman spectrum be HW, the following condition is satisfied: HW > 138-0.06 T. This carbon material is manufactured by thermally treating a carbon precursor by burining it in an inert gas atmosphere flown at a flow rate of 0.1 ml per minute or more per one gram of the carbon precursor at a temperature of 600 ~C or high, or in an atmosphere pressurized at 50 kPa or less at a temperature of 600 ~C or high. In this case, the carbon precursor is placed in a layer so that the contact area of the precursor with the atmosphere is 10 cm2 or more.

Patent CA-2162661-A1 (CA)
Title: Beverage dispensing control
Inventor: BETHUY TIMOTHY W
IPC: B67D1/12
Filed: 1995-11-10
Abstract: An electronic control for an automatic filling beverage dispensing valve is shown. The dispensing valve includes a valve body, a flow control mechanism and a solenoid. The valve further includes an electrically conductive cup actuated lever for operating a micro-switch that is operatively connected to the electronic control of the present invention. The valve body includes a nozzle and a stainless steel electrical contact for providing electrical connection between the electronic control and the beverage as it flows through the nozzle into a cup. The electronic control the present invention is microprocessor controlled and includes an internal signal generator which generates a signal independent of the input line frequency supplying the power to the control. This generated signal is buffered and applied to the dispensing cup lever while simultaneously being applied to a reference input of a phase-locked loop detector circuit. When beverage fills a cup to the rim thereof the beverage can flow over the rim and thereby provide an electrical continuity between the electrically conductive lever and the stainless steel contact within the nozzle. Thus, a signal is conducted to an input of the phase locked-loop detector circuit where that electrical signal is compared to the generated reference signal. If the two signals are matched in both frequency and phase, the detector circuit generates a continuity detected signal to the micro-processor. The microprocessor thereby ends dispensing by de-energizing the solenoid.

Title: Flow cytometer jet monitor system
Inventor: VAN DEN ENGH GER
IPC: G01N15/14
Filed: 1995-10-13
Abstract: A direct jet monitor (66) illuminates the jet of a flow cytometer in a monitor wavelength band which is substantially separate from the substance wavelength band. When a laser is used to cause fluorescence of the substance, it may be appropriate to use an infrared source (67) to illuminate the jet and thus optically monitor the conditions within the jet through a CCD camera (68) or the like. This optical monitoring may be provided to some type of controller or feedback system (34) which automatically changes either the horizontal location of the jet, the point at which droplet separation occurs, or some other condition within the jet in order to maintain optimum conditions. The direct jet monitor (66) may be operated simultaneously with the substance property sensing and analysis system so that continuous monitoring may be achieved without interfering with the substance data gathering and may be configured so as to allow the front of the analysis or free fall area (7) to be unobstructed during processing.

Filed: 1996-01-17
Abstract: A safety system the structure of which is based on a microcontroller (1) which carries out readings of the orders to open (LA) and to close (LC), (together with the speed (V) of the vehicle), a relay for the order to close (2) governed by a transistor (5), and a relay for opening (3) governed by a transistor (6), these two relays and their transistors (5) and (6) being powered by another transistor (7). The system carries out periodical supervision thanks to clock signals generated by the microcontroller (1) of the state of the switching transistors, checking that the orders given are definitive and coincide with the action that has been brought about, entering if this is not the case into a routine of internal stoppage of the microcontroller (1), shutting off motor traction, and bringing the relay contacts into a safe position which prevents the untimely opening of an automatic door. In the case of a fault arising in the microcontroller the relays are deactivated.
