Title: Absorbent media circulating apparatus
Inventor: PRESSLEY DAVID
IPC: A47L7/00
Filed: 1995-07-13
Abstract: A powder circulating apparatus provides a closed loop system  for  delivering  an  absorbent  media  to  an  area adjacent a tire at which wearing of the tire surface is occurring,  conveying away the absorbent media and those materials  absorbed by or entrained with the absorbent media, and recirculating the absorbent media to the tire adjacent area.  The apparatus advantageously permits the delivery of the absorbent media from one of a pair of spray locations so as to take advantage of the air flow adjacent the tire due to the direction of the rotation of the tire.

Filed: 1995-12-01
Abstract: The system allows radio broadcast listeners to use a telephone to connect to a database that contains prerecorded audio descriptions (e.g- spoken text and/or music) of material played by the radio station. The database is indexed by the radio station's program schedule or play list to allow the user to select a particular audio description of interest (e.g. the song currently airing, the song last played, etc.). Hearing the audio description over the telephone insures the listener that the requested selection is in fact correct.

Inventor: SHARMA SUDHIR KUMAR
IPC: F27D99/00
Filed: 1992-07-03
Abstract: An apparatus and method for providing a selected atmosphere at and within an opening to the interior volume of a furnace.  Two or more paralleled diffusers adjacent to the furnace opening laminarly emit different fluids and provide a multi-layer fluid curtain over the opening.  The curtain has a composite modified Froude number from 0.05 to 10, and a thickness at emission of at least 5% of its extent in the flow direction.  Partially covering the outside of the curtain is an optional, substantially flat, outer shield with an aperture coinciding with the furnace opening, which reduces the necessary flow rates of fluids.  Optional side shields around the sides of the curtain also reduce the necessary fluid flow.     A preferred diffuser comprises a porous tube in a housing with an outlet directed to emit fluid across the furnace opening.  The outlet is covered with a screen to disperse the fluid flow and to protect the porous tube.

Title: Device and method for controlling attachment of construction machine
Inventor: TOZAWA SHOJI
IPC: E02F9/24
Filed: 1995-10-13
Abstract: During manual operation, pilot pressure discharged from a pilot pump (41) is fed from a manual operation valve (44a) or  (44b) through an electromagnetic change valve (49a) or (49b) to a main control valve (33). During automatic operation, pilot pressure which is output from an automatic-mode selecting valve (46) is fed through an electromagnetic proportional control valve (48a) or (48b) as well as an electromagnetic change valve (49a) or (49b), all of which are controlled by a controller (21), to main control valve (33).  When limiting the operation range of the attachment during manual operation, pilot pressure output from manual operation valve (44a) or (44b) is fed through electromagnetic proportional control valve (48a) or (48b) as well as electromagnetic change valve (49a) or (49b) to main control valve (33).  At that time, main control valve (33) is returned to the neutral position by causing electromagnetic proportional control valve (48a) or (48b), which are both controlled by control signals from controller (21), to block the pilot pressure.

Patent CA-2189304-A1 (CA)
Inventor: TAKEUCHI ATSUSHI
IPC: B29C45/26
Filed: 1996-10-31
Abstract: A process for producing a bumper for a vehicle uses a first step of injecting an outer layer forming material into a bumper forming cavity through a gate in a mold, and a second step of injecting a core forming material, thereby allowing the core forming material to flow into the outer layer forming material existing in said gate and said cavity, while allowing the outer layer and core forming materials to flow within the cavity.  In the mold, the volume of a mounting portion forming area of the bumper forming cavity is set so that the thickness t1 of at least a mounting portion of the bumper for mounting to a vehicle body to extend laterally from a central portion of the vehicle body can be larger than the thickness t2 of a bumper main portion excluding the mounting portion, and the gate opens into the mounting portion forming area.  Thus, the outer layer forming material can be allowed to flow substantially uniformly over the entire cavity, thereby enhancing the filling rate of the core forming material.
