Patent CA-2647731-A1 (CA)
Inventor: GARCIA MARIA FERNANDA
IPC: C09K3/18
Filed: 2007-04-04
Abstract: An antifreeze composition comprising one or more metal chlorides, in particular, calcium chloride and magnesium chloride, and a solution having an alkaline pH in which at least one of the following ions is dissolved: Bromide (Br-), Bicarbonate (HCO3-), Borate (BO3 3-), Silicate (SiO3-), Fluoride (F-), Iodine (I-). this composition is capable of providing an effective antifreeze action, for example on roads, airstrips and vehicle windows, also in conditions of extremely cool temperatures. In fact, the composition remains in the liquid state even at very low temperature reducing, in particular, the environmental impact with respect to the solutions of prior art. This is possible because the interaction existing between a metal bivalent ion 10, such as Ca2+, or Mg2+, and a chloride ion (Cl-) 20, in the antifreeze composition brings the ions at a high balancing distance "R". This is due to the presence of at least one weak ion 15, for example Bicarbonate (HCO3-), Borate (BO3 3-), Iodine (I-), Fluoride (F-), etc. that interacts with the ions of the bivalent metal and of the chloride.

Inventor: LYNGSTADAAS STAALE PETTER
IPC: A61K33/24
Filed: 2007-09-11
Abstract: The present invention teaches the use of a metal or an oxide of a metal having a capability of reducing the amount of the chemokine IP-IO in a sample and/or reducing the production of IP-IO in cells. The metal is a metal of group 4 or 5 in the period table of the elements and preferably titanium. These metals and metal oxides can selectively bind IP-IO to its surface to thereby scavenge IP-IO from the surrounding medium. In addition, a metal-cell contact induces a reduction in the production of IP-IO from IP-IO producing cells. The metals and metal oxides of the present invention can therefore be used for treating and/ or preventing medical conditions characterized by adverse IP-IO expression, such as inflammatory reactions.

Abstract: The present invention relates to a scanning system optimized for lidar that includes a nodding mirror, a rotary electromagnetic drive, a rotary optical encoder, and control circuitry. The rotary electromagnetic drive includes a yoke incorporating a permanent magnet, and an arm having a coil at one end of the arm. The coil is enclosed within the yoke, and an opposite end of the arm is coupled to the nodding mirror, such that movement of the coil within the yoke in response to a current causes the nodding mirror to rotate. The rotary optical encoder produces an output signal in response to rotation of the nodding mirror, which serves as feedback to the control circuitry. The control circuitry adjusts the current provided to the rotary electromagnetic drive in response to the output signal, such that the nodding mirror rotates in a reference scan pattern.

Title: Railroad gondola car structure and mechanism therefor
Inventor: FORBES JAMES W
IPC: B61D7/00
Filed: 2009-09-11
Abstract: A railroad gondola car has a hopper carried between two trucks. The hopper has convergent end and side slope sheets that feed a bottom discharge. The bottom discharge has a pair of longitudinal doors. The door closing mechanism is a mechanical transmission that includes a set of linkages running from the door to a reciprocating pneumatic cylinder. The linkages run generally parallel to the slope sheet. The car has a very short draft installation that includes a removable coupler carrier bar, and the main shear plate has a removable draft gear installation panel. There is a machinery space above the end section shear plate. It is overhung by the slope sheet that is substantially unobstructed by any other primary structure. The pneumatic cylinder is mounted on an angle in this unobstructed machinery space, oriented longitudinally over the draft sill beneath the main drag link of the mechanical transmission, and above the main pivot of the driving input lever of the transmission. The main lever is bifurcated, and straddles the pneumatic cylinder. The mechanism includes a primary lock in the form of an over center lever arrangement, and a compact secondary lock that acts sideways rather than lengthwise. The sidewalls of the car include vertical stiffeners and side sheets. The lower portion of the side sheets lies laterally inboard of the stiffener web, while the upper portion lies laterally outboard of the stiffener web. The side slope sheet of the hopper meets the sidewall at the transition of the sidewall sheet from the inside-the-post to the outside-the-post condition.
