Patent CA-1120296-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE           A microfiche reader according to the present invention includes a housing consisting of a hood portion and a base por-tion, a screen located within the hood portion and visible through the front end of the hood, a combined microfiche carriage and index holder, a lens assembly and a projection system.  The com-bined microfiche carriage and index holder serves to accurately locate the microfiche with respect to the index grid.  By reason of the fact that there is no relative movement between the index grid and the microfiche in use, it is always possible to accurately locate the microfiche with respect to the projection system by reference to the index grid.  The index grid is illuminated by an index illuminating lens carried by the housing.  The illuminating lens is located in a fixed relationship with respect to the pro-jection path which again contributes to the facility with which the microfiche may be accurately located in the projection path. The lens assembly includes a support plate mounted above the microfiche carriage and a slide member mounted in the support plate and a pair of lens members mounted in the slide members so that either one may be located in the projection path as re-quired.  The projection system includes a demountable modular unit which may be easily mounted in and removed from the housing. A prefocussed lamp is mounted on the modular unit and the position of the prefocussed lamp with respect to the modular unit may be adjusted so as to vary the length of the illuminating path between the prefocussed lamp and the condenser means whereby the optical system may be adjusted to accommodate objective lenses having different characteristics.  The projection system consists of a prefocussed lamp which projects a beam of light onto a cold mirror which reflects the beam of light through an optical con-denser which in turn directs the beam of light through the micro-fiche to an objective lens mounted thereabove.  A first surface mirror is mounted in the housing and reflects the bean of light emitted from the objective lens to a viewing screen mounted in the housing.  The viewing screen consists of a unitary body of molded plastics material having an image receiving surface formed with a concave spherical curvature.          The image receiving surface may be plated with a suitable coating to form an image reflecting coating thereon.

Abstract: JLS:pm 6/28 Case 5705 TRUCK FOR RAILROAD CARS              ABSTRACT OF THE DISCLOSURE    A truck for a railroad car has a front and rear wheel-set with axle ends rotatively carried in a front and rear steering arm, respectively.  The steering arms are carried in pedestal jaws of a right and left side frame with resilient pads interfacing between the steering arms and the side frames.  The resilient pads allow each wheelset and steering arm to rotate or yaw to an out-of-square condition with respect to the side frame as the railroad car proceeds, for example, around a curve in the track on which the car is traveling.  This rotational movement is selectively regulated by a joint connecting the front and rear steering arms.                             -i-

Abstract: ABSTRACT OF THE DISCLOSURE              A weathertight sash window assembly including a pair of first and second engaging members disposed on and extending longitudinally of a pair of meeting first stile and second stile, respectively.  The first engaging member is movable between a first position in which the first engaging member  pulls or draws the second engaging member toward the interior of the window assembly to force the second stile into a firm engagement with the first stile throughout their length, and a second position in which the first engaging member releases the second engaging member to allow disengagement of the sashes from each other.  The sash window assembly further includes means on the first stile for moving the first engaging member between the first and second positions in response to movement of a first fastener member between its locked and unlocked positions.  The advance in the art is in that a uniform engage-ment between the sashes  is achieved to improve the sealing effect of the window assembly.

Title: Hydrogen sulfide concentrator for acid gas removal systems
Inventor: NICHOLAS DAVID M
IPC: B01D53/14
Filed: 1980-11-06
Granted: 1982-07-06
Abstract: ABSTRACT A novel method is disclosed for treating a con-taminated gas such as a contaminated natural gas or a synthesis product gas from the partial oxidation of petroleum or coal to concentrate and remove hydrogen sulfide at a reduced energy and capital requirement. Hydrogen sulfide in the contaminated stream is absorbed to form a hydrogen sulfide rich solvent which includes co-absorbed carbon dioxide, which is then removed to prevent dilution of the concentrated hydrogen sulfide formed when the solvent is regenerated. The solvent leaving the hydrogen sulfide absorber is heated before entering a high pressure stripper column wherein the co-absorbed carbon dioxide is stripped from the solvent, preferably by stripping with nitrogen or a portion of the product gas, and the carbon dioxide is recycled to the hydrogen sulfide absorber. The C02 stripper is operated at a pressure not substantially below the pressure of the hydrogen sulfide absorber, eliminating the need for large compressors required in conventional methods to recycle the carbon dioxide.

A welding bar having heated fin portions on its upper and lower sides is then passed between and in contact with the support rod and the profile wires to slightly melt them.  The welding bar is then quickly removed and the support rod is quickly moved downwardly against the profile wires and held until the integral joints formed at each inter-section are solidified.  Additional support rods are welded to the profile wires at spaced intervals until the desired screen length has been reached.

Abstract: ABSTRACT OF THE DISCLOSURE                 TIRE PRESSURE SENSING SYSTEM        A pressure indicating system for continually monitoring tire pressure in a moving vehicle in which a pressure sensing means attached to the wheel activates an alarm to alert a driver that the pressure in one of his tires is abnormally low.  A magnet is shifted by the pressure sensing means to activate a Hall effect switch located on a non-rotating portion of the vehicle to trigger the alarm.        The pressure sensing means also acts to relieve high pressure above a predetermined pressure from the tire to prevent over pressurizing of the tire.  The alarm indicates which of the tires is at low pressure and preferably comprises an inexpensive electronic system having a flashing light for indicating which tire is at low pressure.

Abstract: ABSTRACT OF THE DISCLOSURE     A magnetic clutch for selectively connecting a rotatable input shaft to a rotatable output hub using magnetic flux.  An output disc connected to the output hub is mounted between a pair of input discs connected to the input shaft.          Magnetic flux passing through the output disc and the input disc clamps the output discs between the input discs.  The magnetic flux linking the input and output discs provide additional torque to cause the output disc to rotate along with the input disc, so a relatively small clutch can provide a large output torque.
