Title: Portable radio communication apparatus not necessitating a shielding case
Inventor: YOKOYAMA YUKIO
IPC: H04B1/38
Filed: 1992-07-10
Granted: 1997-10-21
Abstract: A portable radio communication apparatus includes a printed circuit board, an antenna section and a radio section installed on the board, a housing, and a connector. The radio section includes electronic parts of which connecting terminals are connected to the printed circuit board and of which conductor sections formed on an outer surface thereof are connected to a grounding section of the board. The housing accommodates therein the printed circuit board, the antenna section, and the radio section. The housing has a conductor film formed on an inner surface thereof. The conductor sections of the electronic parts are connected to the conductor film on the inner surface of the housing via connectors. Since the conventional type of shielding case and connector are unnecessary, the size and weight of the apparatus can be reduced.
Patent CA-2077220-C (CA)
Title: Steam box
Inventor: KOIVUKUNNAS PEKKA
IPC: D21G7/00
Filed: 1992-08-31
Granted: 2004-02-17
Abstract: The present publication discloses a steam box comprising means (4, 10, 13, 16) for distributing steam onto a web (1) being calendered, at least one valve (5, 6, 7) connected to said steam distributing means and capable of controlling the blowing of the steam onto the web (1) and elements (3, 25, 15, 16, 9) for feeding hot steam to the valve (5, 6, 7). The invention is based on having in each valve (5, 6, 7) at least three steam channels, namely an inlet channel (22) for feeding the steam to the valve, an outlet channel (23) of the, valve for feeding the steam onto the web (1) and a recirculation channel (24) for recirculating the steam, and a check element (20) for controlling and dividing the incoming steam flow from the inlet channel (22) between the outlet channel (23) and recirculation channel (24) of the valve, and a return pipe (27) connected to the recirculation channels (24) of the valves (5, 6, 7), capable of routing the steam directed to the recirculation channel (24) of the valve (5, 6, 7) to, e.g., the condensate return line of the steam distribution system. By virtue of such a circulation the valve can be kept warm even when no steam is directed via said valve, thus preventing the formation of droplets and their blowing onto the web.

Title: Methods and systems for recovering subsurface materials
Inventor: LYNCH R LARRY
IPC: E21B43/12
Filed: 1993-04-01
Granted: 1994-11-01
Abstract: Methods and systems for recovering groundwater, gases and vapors from subsurface locations in a single, integrated operation by applying a vacuum to groundwater recovery wells are disclosed.  Selective recovery of specific contaminants from zones of interest containing high levels of those contaminants is achieved by manipulating the local water table level.  Groundwater recovery systems may also utilize eductor systems having venturi nozzles that create a vacuum networked.  A plurality of such recovery wells operated using eductor systems may be operated by a single pump at or above grade level.  In this fashion, a network of recovery wells may be operated using a single pump and control system.  The recovery methods and systems of the present invention are preferably utilized in association with known contaminant removal systems to provide complete removal of contaminants and improved remediation efficiencies.

Title: Machine and method for forming arched roof vertical wall self supporting metal buildings and building constructions
Inventor: MORELLO FREDERICK
IPC: E04B1/35
Filed: 1993-04-21
Granted: 2004-07-06
Abstract: A mobile metal building forming machine (30, 34, 38, 40, 68, 74) forms a panel (P) of predetermined length from a coil of flat metal and then the formed panels are continuously crimped on their side edges (C s) for strength and are selectively curved by crimping the bottom (C b) of the panel. The crimping and curvature are automatically controlled so that building panels with vertical walls and an arched roof may be formed. A moveable crimping roll (70, 72) is automatically portioned to control the curvature and the roll is chain driven (94, 98, 102) so that it may be moved without affecting its rotational drive.

Filed: 1992-07-24
Granted: 1999-12-21
Abstract: The invention provides that a former (A, B, C) is used for forming scrolls from strip metal (30).      The former has a scroll flight which is in two parts (A,B) which are relatively movable in the direction of the axis about which the former (A, B, C) rotates to coil the strip (30) about said flight (A, B) by drawing it radially into the former. In the first stage of the process the strip (30) is coiled about the inner part (A) of the flight, the outer part (B) being held displaced axially so as not to interfere with the initial coiling by the strip (30), until the strip (30) clears the end of the outer part (B) of the flight which then moves into the plane of the inner part (A) of the flight and coiling can continue onto the outer part (B). The apparatus also includes additional mechanisms for making circle and arches from the strip and for cutting, punching, twisting and right angle bending the strip from the same drive.

Abstract: A method and apparatus for effecting the continuous reliable supply of sodium bicarbonate particles to a blasting nozzle employing pressured air or water for conveying such particles into contact with a surface to be cleaned. A hopper having an inclined bottom surface terminating in a central aperture is provided for containing a mass of sodium bicarbonate particles. One of a plurality of different sized orifices are mounted in a central aperture in the bottom of the hopper and the discharge passage through such orifice is in transverse communication with a pair of pipes. One pipe is exposed to the atmosphere through an adjustable flow valve. The other pipe is connected by a hose to a venturi passage provided in the blast nozzle, thus creating a suction flow of air through the pipe to convey particles passing downwardly through the selected orifice to be injected into the pressured fluid passing through the applicating nozzle. The amount of air flow permitted through the pipe by the adjustable flow valve is coordinated with the aperture size of the particle feeding orifice, which in turn is a function of the size of the particles of sodium bicarbonate being utilized, to produce a volume flow of sodium bicarbonate particles which at no time occupies more than 25 percent of the cross-sectional area of the pipe and the hose connected to the applicating nozzle.
