Title: Apparatus for form-fitting shoes, and other articles of footwear
Inventor: BROWN DENNIS N
IPC: A43D3/08
Filed: 1996-05-03
Abstract: An apparatus for internally expanding an article of footwear. A hand-operated pressure assembly is provided, in which a knob is manually rotated in order to transversely extend first and second piston members. Hemispherical bearing surfaces on the ends of the piston members are received in corresponding receptacles formed in the legs of a hinged spreader assembly; as the pistons extend outwardly, the spreader assembly is forced against and stretches a selected interior portion of the article of footwear. Cupped overlay members are provided for detachable mounting to the legs of the spreader assembly so as to permit selective adjustment of its width to match that of the particular shoe or boot on which the work is being performed. Preferably, the hydraulic fluid which is used in the pressure assembly is ordinary tap water, so that leakage does not represent a hazard in a retail environment.

Title: Improved, adjustable tool for dispensing viscous material, such as two-part adhesive
Inventor: TIMMERMAN MARK S
IPC: B05C17/005
Filed: 1996-05-27
Abstract: An adjustable tool is disclosed for dispensing a two-part adhesive from a two-chamber cartridge having a mixing nozzle with each chamber having a plunger. Pistons are insertable into the respective chambers. Piston rods and a drive rod move conjointly with the pistons. A lever is pivotable on the frame. A feed nut is mounted loosely on the drive rod so as to be capable of gripping the drive rod when canted for moving the feed nut, the drive rod, the piston rods, and the pistons conjointly to a forward limiting position of the feed nut when the lever is actuated. A spring biases the feed nut backwardly and permits the feed nut to be canted, to grip the drive rod, and to be moved forwardly and conjointly with the drive rod, the piston rods, and the pistons when the lever is pivoted into an actuated position. A set screw threaded adjustably into a threaded hole in the frame defines a backward limiting position of the feed nut. The screw head engages an outer margin of the threaded hole, in a counterbore, to provide an inner limit to threading of the set screw. A cover mounted over the threaded hole has an access hole sized to permit a screwdriver tip of a smaller size but not the screw head to pass and engages the screw head at an inner margin of the access hole so as to provide an outer limit to unthreading of the set screw.

Title: Brake Control for Multi-Platform Freight Car
Inventor: SICH GARY M
IPC: B61H11/06
Filed: 1996-07-23
Abstract: A brake system is provided for a multi-platform railroad car in which a single microprocessor is employed to control the car brakes. In one embodiment, a single electro-pneumatic control unit provides a common brake pressure to the brakes of each truck in accordance with the truck design net brake ratio and load weight of whichever truck requires the lowest brake pressure. In a second embodiment of the invention, the brakes on separate truck sets are provided with different common brake pressures by employing separate electro-pneumatic control units for each truck set under control of the microprocessor. In such an arrangement, the different common brake pressure on one truck set can be increased to make-up at least a portion of a brake deficit on another truck set due to light car loads associated with the other truck set in order to meet or at least closely approach the commanded net braking ratio for the entire multi-platform car.

Inventor: SMITH PAUL FIELDING
IPC: H04B1/40
Filed: 1995-12-05
Abstract: A multi-channel digital transceiver (400) receives uplink radio frequency signals and converts these signals to digital intermediate frequency signals. Digital signal processing, including a digital converter module (426), is employed to select digital intermediate frequency signals received at a plurality of antennas (412) and to convert these signals to baseband signals. The baseband signals are processed to recover a communication channel therefrom. Downlink baseband signals are also processed and digital signal processing within the digital converter module (426) up converts and modulates the downlink baseband signals to digital intermediate frequency signals. The digital intermediate frequency signals are converted to analog radio frequency signals, amplified and radiated from transmit antennas (420).

Patent CA-2186105-A1 (CA)
Inventor: WAYMOUTH ROBERT M
IPC: C08F10/06
Filed: 1995-03-24
Abstract: Cette invention concerne de nouveaux catalyseurs dont la structure et l'activité peuvent être modulées pour produire une grande variété de polymères et de copolymères d'alpha-oléfines, et pour produire de préférence des polyalpha-oléfines stéréoséquencées comprenant une grande variété de segments amorphes et cristallins présélectionnés afin de moduler avec précision leurs propriétés physiques, principalement leurs propriétés thermoplastiques élastomères. Plus spécifiquement cette invention concerne de nouveaux catalyseurs et systèmes de catalyseurs qui permettent de produire du polypropylène stéréoséquencé comprenant des diastéréo-séquences isotactiques et atactiques, ceci ayant pour effet de donner une grande variété de propriétés élastomères. La quantité et le nombre des parties cristallines, la teneur en pentades isotactiques, le nombre et la longueur des chaînes atactiques intermédiaires et la masse molaire globale peuvent tous être modulés par la structure stérique des catalyseurs et par les conditions du processus. Les nouveaux catalyseurs de cette invention sont des alliages organométalliques non rigides porteurs de ligands dont la géométrie peut être modulée sur une échelle de temps qui est plus lente que la vitesse d'insertion des oléfines, mais plus rapide que le temps moyen nécessaire pour construire (polymériser) une chaîne polymère unique, afin d'obtenir une structure stéréoséquencée dans les polyoléfines produites. La symétrie de la structure du catalyseur est telle que lors de l'isomérisation, cette symétrie alterne entre une géométrie chirale et une géométrie achirale. On peut moduler cette modification de la géométrie en sélectionnant la structure et le type des ligands et en modulant les conditions de polymérisation de manière à moduler avec précision les propriétés physiques des polymères résultants.
