Title: Railcar cushion device tester and method
Inventor: LITTEN GLEN L
IPC: G01M17/08
Filed: 1994-03-04
Abstract: RAILCAR CUSHION DEVICE TESTER AND METHOD                ABSTRACT OF THE DISCLOSURE       A railcar cushion device is tested by applying a force necessary to move the cushion device in a controlled motion at a predetermined velocity or velocities according to a motion profile.  The cushion device's performance is analyzed by measuring the force applied at various positions during the motion profile and comparing the force to a standard for cushion devices in good condition at the positions. Alternatively, a damping coefficient or other performance parameter for the cushion device is calculated from the force applied and position of the cushion device and compared to a standard to analyze cushion device performance.  A tester for performing cushion device testing comprises a hydraulic ram and an electronic motion controller for applying the force to the cushion device.  The motion controller uses motion feedback from a position transducer to provide the controlled motion to the cushion device.

Patent CA-2120837-A1 (CA)
Inventor: BRAGG JAMES R
IPC: E02B15/04
Filed: 1994-04-08
Abstract: A method is disclosed for removing spilled oil from shorelines, other solid surfaces, or from the surface of a body of water by adding to the surface a mixture of fine hydrophilic mineral solids dispersed in an aqueous liquid that interacts with the oil to form buoyant mineral fines-oil floccules.  These floccules reduce the tendency of the oil to adhere to solid surfaces or to re-coalesce, thus facilitating dispersion and removal of the oil.

Title: Animal feeder
Inventor: CATELLIER RONALD J
IPC: A01K5/00
Filed: 1994-05-13
Abstract: ANIMAL FEEDER          ABSTRACT OF THE DISCLOSURE A feeder for hogs comprises a cylindrical outer wall which is upstanding from the floor to a height above the shoulder of the animal. A feed supply duct is arranged coaxially with the wall along a centre part of the feed area within the wall and discharges feed downwardly to escape from a lower end of the duct to spread slightly outwardly across the floor at the base of the feeder.  Between the duct and the wall is provided a plurality of radial extending angularly spaced divider plates each of which extends from the floor to the top of the wall.  This forms a plurality of compartments each of which is accessible by a hole through the outer wall of shoulder width so that only a single animal can reach into the compartment through the hole for feeding without disturbance by surrounding animals.  A seperate base pan can be provided to be inserted into the lower end of the feeder.  The feeder is of a simple construction and provides efficient feeding due to reduced competition of the animals.

IPC: B23K3/06
Filed: 1992-12-02
Abstract: A cover plate (34) extends over a solder reservoir (10) and has a slot (40) for a solder wave (22) to extend up above the plate, a gas excluding oxygen is supplied under the cover plate (34) and flows up through the slot (40) on both sides of the solder wave to blanket the solder wave.

Patent CA-2128964-A1 (CA)
Inventor: OSATO YOICHI
IPC: G11B11/105
Filed: 1994-07-27
Abstract: A magnetooptical recording medium is constituted by laminating at least a first magnetic layer and a second magnetic layer in an order named on a substrate which has transparency and on which receiving a laser beam is incident.  The coercive force of the second magnetic layer is greater than that of the first magnetic layer.  The coercive force of the second magnetic layer is greater than o~/2M~2h2, where ~w is a magnetic wall energy between the first and second magnetic layers, M~2 is a saturation magnetization of the second magnetic layer, and h2 is a film thickness of the second magnetic layer.  The coercive force of the first magnetic layer is grater than ~w/2M~1h1, where M~w is a saturation magnetization of the first magnetic layer, and h1 is a film thickness of the first magnetic layer.  The compensation temperature of the first magnetic layer is smaller than the Curie temperature of the first magnetic layer.  A method of recording information on the magnetoopical recording medium is effected as follows.  A direction of a magnetic moment of the first magnetic layer is aligned in one direction by applying an external magnetic field thereto.  A laser spot with low power is irradiated to the medium while applying a recording bias magnetic field in the same direction as the direction of the external magnetic field so as to form a first recording bit in a high temperature region in the laser spot.  A laser spot with high power is irradiated to the medium while applying the recording bias magnetic field so as to form a second recording bit in which a magnetic wall is present between the first and second magnetic layers, in the high-temperature region in the laser spot.  One of the first bit forming recording and the second bit forming recording is selectively determined in correspondence with information.

Filed: 1993-04-23
Abstract: Bioadhesive polymers in the form of, or as a coating on, microcapsules containing drugs or bioactive substances which may serve for therapeutic, or diagnostic purposes in diseases of the gastrointestinal tract, are described. The polymeric microspheres all have a bioadhesive force of at least 11 mN/cm2 (110 N/m2).  Techniques for the fabrication of bioadhesive microspheres, as well as a method for measuring bioadhesive forces between microspheres and selected segments of the gastrointestinal tract in vitro are also described. This quantitative method provides a means to establish a correlation between the chemical nature, the surface morphology and the dimensions of drug-loaded microspheres on one hand and bioadhesive forces on the other, allowing the screening of the most promising materials from a relatively large group of natural and synthetic polymers which, from theoretical consideration, should be used for making bioadhesive microspheres.

Title: Tire curing bladder with improved release from the tire innerliner
Inventor: PATITSAS GEORGE P
IPC: B29K21/00
Filed: 1994-11-03
Abstract: Disclosed are expandable bladders for use in curing presses for hydrocarbon rubbers such as pneumatic tires. The  bladders  are  a  crosslink  elastomer  comprising isobutylene repeat units and the bladder composition includes graphite.  A preferred isobutylene elastomer is a  brominated   copolymer   of   isobutylene   and  p-methylstyrene.   The bladders have enhanced lubricity, low adhesion to tire innerliners, and lower hot tension set.  The above enhancements allow hydrocarbon rubbers such as  tires to be molded with fewer defects caused by abraded or deformed bladders.   They also enhance the useful life of the bladder reducing the cost of tire curing.

Filed: 1995-02-23
Abstract: A  hydroforming  process  and  apparatus  for  manufacturing components  of  a  vehicle  exhaust  or  intake  manifold.    The hydroforming process is utilized to form a tubular member to the desired configuration for use in a manifold.  The tubular member is loaded into a hydroform press and filled with a suitable liquid. The liquid within the tube is pressurized in order to maintain a predetermined internal fluid pressure which prevents collapse and crimping of the tube during forming.  The hydroform press includes two sets of dies to form a compound bend in the pressurized tube. Upper and lower dies close on the tube first to bend the tube in a vertical plane.  Horizontal dies are wedged inwardly spreading the first die set and bending the tube in a horizontal plane.  As a result, a compound configuration may be placed on the tube making it suitable for use in a vehicle manifold.
