Inventor: FOWLE ROBERT C
IPC: E01D19/06
Filed: 1995-08-09
Abstract: A method for sealing an expansion joint to inhibit leakage includes the steps ofcollapsing a generally hollow resilient sealing element by creating a vacuum therein such that the width of the sealing element becomes less than the width of the expansion joint; and then positioning the sealing element within the expansion joint and releasing the vacuum so that the sealing element expands to fill the expansion joint allowing adhesive to act between the sealing element and the expansion joint. An expansion joint sealing kit is also provided.

Title: Manufacture of metallic strip
Inventor: FEHRSEN JOHANNES HENDRIK
IPC: B21B37/24
Filed: 1994-02-11
Abstract: A method and apparatus for manufacturing metallic strip (20) with a varying thickness is described. The metallic strip is particularly for use as part of a windscreen wiper blade assembly. Feedstock (14) having a constant thickness and width is passed in a cold condition through a pair of opposed forming rollers (16, 16) and the separation of the rollers is varied thereby deforming the feedstock in a varying manner along the length thereof to provide formed strip with a varying thickness. The rollers (16, 16) have parallel axes with one axis being fixed and the other axis being displaced back and forth. The thickness of the formed strip varies in a ratio of 3:1. The formed strip is heat treated in a varying manner. The amount of power supplied to heat the strip varies in accordance with the thickness of the strip. A preferred roller arrangement (15) has a pair of rollers with each roller being supported by bearings located intermediate its ends to provide an exposed end portion, with the rollers being offset and with the end portions overlapping. The overlapping end portions define a rolling region between them.

Title: Pressurized fluid dispensing nozzle
Inventor: FRY DAVID ANDREW
IPC: F17C5/02
Filed: 1994-05-13
Abstract: A pressurized fluid dispensing nozzle (110') such as for LPG is screw-threadedly engageable with a tank inlet (192) such as on a vehicle. A sealing sleeve (154) carrying a nose piece (140') is biassed into abutment with a gasket (194) on a seal face (196) of the tank inlet and is urged rearwardly by the abutment. The sealing sleeve (154) is slidably mounted on a sealing member (136') which is urged rearwardly with the sealing sleeve (154) into a valve actuating condition. A trigger (118') is actuated to open a valve assembly (120') by shifting the valve assembly forwardly to bring a valve body (126') into abutment with an actuator (132') on the sealing member (136) which lifts the valve body off a valve seat (128'). The pressurized fluid passes along a passage (146') through the sealing member (136') to be dispensed but part of it enters a chamber (150) through ports (134'). The pressurized fluid in the chamber (150) acts on the sealing sleeve (154) to drive it into sealing engagement with the tank inlet gasket (194) or, if the gasket is missing, with the seal face (196).

Title: Composition and process for prepainting treatment of plastics
Inventor: FURUYAMA OSAMU
IPC: C08J7/043
Filed: 1994-08-09
Abstract: Water-based liquid compositions  for treating plastic moldings prior to the painting thereof contain as essential component at least 0.05 weight % of at least one selection from carboxylic acids that do not contain any terminal alkyl group in their molecular structure and hydroxycarboxylic acids that do not contain any terminal alkyl group in their molecular structure. The surface bleed of the internal additives present in plastic moldings can be inhibited by treatment with the water-based prepaint treatment compositions in accordance with the present invention.  This results in an inhibition of timewise changes in the paint-receiving surface and thus stabilizes the paintability.
Patent CA-2172937-A1 (CA)
Title: Pallet container
Inventor: SCHUETZ UDO
IPC: B65D77/06
Filed: 1996-03-28
Abstract: In the pallet container which is equipped with a plastic inner container and a lattice jacket of vertical and horizontal lattice rods (9, 10) of metal, stacking and transport safety is achieved by special design of intersections (15) where lattice rods (9, 10) are welded to one another.      At intersections (15) lattice rods (9, 10) are indented to form double-walled, cavity-like depressions (16).  Depressions (16) have center elevation (17).  At each intersection (15) between longitudinal edges (18, 19) of center elevations (17) of depressions (16) of two lattice rods (9, 10) which lie at right angles on top of one another, this shaping of lattice rods (9, 10) results in formation of four contact points (20) which lie in one plane, each with a material accumulation which corresponds to four times the wall thickness of the lattice rods.  Lattice rods (9, 10) are joined to one another by electrical resistance pressure welding or electrical spot welding at intersections (15) in the area of four contact points (20).      Sections (25, 26) of cavity-like depression (16) of lattice rods (9, 10), the sections adjacent on each side to elevation (17) with contact and welding points (20), form bending points of limited elasticity with a bending resistance moment which is reduced relative to elevation (17) to relieve the welds at intersections (15) under static and/or dynamic loading of the lattice jacket.

Abstract: A dental magnetic attachment, which is embedded in the denture base so as to face a soft magnetic keeper 103 and attract the keeper by magnetic force, comprising at least three yokes which are plates and made of soft magnetic material, and at least two pieces of magnet which have the magnetization direction parallel to the thickness.    In the example the attachment comprises a central yoke 10, the magnet 1, the magnet 2, the outer yoke 11, and the outer yoke 12.    The invention is characterized by a magnet arrangement in which like poles of the magnet 1 and the magnet 2 faces each other. Because of it mutually independent two magnetic circuits are formed and they offer strong attractive force which is two times larger than that of existing ones in a compact volume required for dental attachment.    Furthermore, corrosion resistance and wear resistance are improved by covering the attracting face of the magnet 1, 2 with spacers made of non-magnetic material and covering the whole attachment with the cap made of non-magnetic material except the attracting face of the attachment.

Title: Mobile terminal and system using variable length abbreviated slot format for reverse digital control channel
Inventor: ALANARA SEPPO
IPC: H04W48/16
Filed: 1996-11-18
Abstract: A method is disclosed for operating a user terminal (10), such as a cellular radiotelephone, of a type that is bidirectionally coupled to a network (32) through an RF interface. The method includes a first step of receiving a message from the network, at least a portion of the message indicating a size of a cell within which the user terminal is located. A second step of the method transmits a message to the network, the message being transmitted so as to include a guard time period that has a duration that is set by the mobile terminal a function of the indicated size of the cell. In a preferred embodiment of the invention the message received from the network is an Access Parameters message. The message transmitted to the network is an Abbreviated Burst, transmitted on a Random Access Channel (RACH), and includes at least one data portion. A number of bits transmitted during the data portion of the message is made inversely proportional to the duration of the guard time period. By example, the number of bits transmitted during the data portion varies within a range of about 200 to about 242. A digital cellular radio communications system that operates in accordance with the variable Abbreviated Burst is also disclosed. A further method of the invention adaptively adjusts the guard time period as a function of a distance between the user terminal and a base station.
