Abstract: ABSTRACT OF DISCLOSURE           A fuel pumping apparatus for supplying fuel to an in-ternal combustion engine includes an axially movable member urged in one direction against the action of a governor spring by means of a centrifugal weight.  A reaction member for the pivot of the weight bears against one member of a dashpot which includes resilient means in the forms of a spring acting in opposition to the force exerted by the governor spring.  A valve controlled passage including a ball element allows substantially unrestricted flow of liquid into the dashpot chamber when the latter is increased in volume by the action of the spring but a restricted leakage path is provided to control the reduction in volume of the dashpot chamber as the force exerted by the governor spring and the weights increases.  The axial setting of the member controls the quantity of fuel which is supplied to an internal combustion engine.

Granted: 1982-02-09
Abstract: ?-BWL     ABSTRACT           In a system including a carburetor for regulating the air/fuel ratio fed to an internal combustion engine, a sensor is positioned in the exhaust pipe to provide a control signal indicating the amount of some exhaust gas constituent, such as oxygen.  A control circuit is provided to regulate the position of a carburetor component, to change the air/fuel ratio as a function of the control signal derived from the exhaust gas sensor.  This carburetor component is continually displaced, either toward a richer or leaner mixture condition, thus in effect integrating the signal from the exhaust gas sensor which ultimately regulates the air/fuel ratio.  Operation of the control circuit is modified as a function of the engine speed and the engine temperature.

Abstract: CANADIAN PATENT APPLICATION             OF SOREN ALBERTSSON        FOR INCINERATOR            Abstract of the Disclosure The invention relates to an incinerator for crematories, in-cluding a combustion chamber provided with charge inlet, flue gas outlet, supply means for combustion air, heat supply means and ash outlet. The novelty resides in the fact that the combustion chamber is placed in a unit which is movable, between two positions, relative to at least one stationary end wall in which the charge inlet and the flue gas outlet are provided, and is divided into at least two compartments which communicate with each other at some distance from the flue gas outlet and are adap-ted to be positioned, one at a  time, at respectively the charge inlet and the flue gas outlet. The heat supply means works in the compartment present at the charge inlet at just that moment, and the combustion gases from said compartment will pass the other compartment on their way towards the flue gas outlet. The essential combustion of a charge introduced into the incinerator takes place in the compartment where the heat supply means is working, at the same time as the final burnout of a preceding charge takes place in the other compartment which has been displaced to a position adjacent the flue gas outlet and through which the combustion gases pass on their way to said outlet.

Abstract: ABSTRACT OF THE DISCLOSURE         Electrical currents and potentials in test leads associated with underground piping, cables and the like are monitored by a test station apparatus which essen-tially includes a collar supported by a tubular plastic conduit for subterranean implantation or carried above-ground by a carrier plate.  A plastic tube projecting from diametrically-opposed sides of the conduit provides one form of anchor means to maintain the conduit within the ground while in another form the anchor means consists of a collar retained on the lower end of the conduit by a sleeve.  Further embodiments include two different forms of carrier plates for aboveground support of the test station.  A collet-type compression fitting is used to attach a collar onto the upper end of the conduit.          Pedestals extend vertically from the end wall at opposed sides of an annular opening in the collar.  The pedestals support a terminal block extending across the annular opening so that test leads pass through the collar for attachment at either side of the terminal block to ter-minals which are normally enclosed by a dome-shaped cover secured to the collar by threads or by one of different embodiments of interlocking members.

Abstract: Abstract of the Disclosure Plastic films or sheets having tear lines formed therein are disclosed.  These films are made by forming a score along a predetermined line in the surface of a plastic film to form a tear line and then restoring the scored film surface without eliminating the line of tear.  The products tear very easily along predetermined lines even though the restored plastic films have enhanced impact strengths.  By restoring the surface of the scored film, score lines become invisible to the naked eye and the useful life of the film is extended.  Single-ply or multi-ply products are disclosed including products having an embossed or textured surface, still without eliminating the capability for a smooth line of tear.  The products have many utilities as structural materials which may be sized or torn by hand, including wall coverings, window shade coverings, ruptur-able packages and envelopes, to mention a few.

Abstract: ABSTRACT        Apparatus for embossing web material such as a heated thermoplastic web material comprises first and second embossing members each having a resilient embossing surface, and means mounting the embossing members for relative movement to define a roll nip between them.  The resilient surface of the first embossing member has a primary embossing pattern thereon and is of harder durometer than the resilient surface of the second embossing member.  Both resilient surfaces are soft enough to be temporarily deformed in the roll nip to press the web mater-ial between them into surface conforming contact with the primary embossing pattern.  The temporary deformation also helps to expel air from between the web material and the primary embossing pattern to insure conforming contact of the web to the embossing pattern.  A secondary embossing pattern is  pro-vided on the resilient surface of the second embossing member and is of lesser depth than the primary embossing pattern.  The temporary deformation assists in providing full contact with both patterns.        A method of embossing the material includes heating the thermoplastic web material to a temperature within its softening range, introducing the heated material to a nip formed between the first and second embossing members, and allowing the embossed material to cool to set the pattern before re-moving it from the first embossing member.

Abstract: ABSTRACT     A tuyere is disclosed with a partition blocking the direct path between the inlet and outlet orifices (16,18) in the main cooling chamber (14).  Guide members (30,32) extend from the far side (from the partition) of the orifices (16,18) towards but not reaching the nose end wall of the cooling chamber (14).  There-fore whichever orifice (16,18) is used as the inlet for cooling fluid, a fast moving stream is ensured at the nose end of the cham-ber (14) near the partition.  This assists the cooling of the tuyere in this area, which otherwise tends to form a marked hotspot, especially when the inlet and outlet orifices (16,18) are close together.

Abstract: METHOD AND APPARATUS FOR DIGITALLY CONTROLLING               THE FORMATION OF COLOUR IMAGES                 Abstract of the Disclosure The colour images are generated by the point-wise over-printing of the individual printing colours by means of an ink jet printer.  During printing of the second and sub-sequent colours the record medium is illuminated with white light and monitored by a two-dimensional opto-electronic device carrying colour filters.  The spectral components measured are transformed into electrical signals used in each colour channel to control droplet generation, ink pressure and droplet deflection for correction in the direction  of movement of the record medium, and to control the print head transport mechanism for correction in the direction orthogonal to the said direction.    The ink jet printer for performing this method com-prises at least three nozzles arranged in a common print head and a white-light source illuminating the image portions printed on the record medium.  An opto-electronic scanner equipped with colour filters is mounted in scanning position.  Its outputs are connected via a control unit to the control inputs of the droplet generators, of the ink supply and the deflection electronic of each individual colour channel as well as with the control inputs of the print head transport mechanism.
