Abstract: ABSTRACT       A method for improving fuel control in an inter-nal combustion engine employs a pressure ratio to deter-mine the engine's actual volumetric efficiency continuously as the engine is operating.  The air/fuel ratio of the engine's combustible mixture is affected by the volumetric efficiency.  The volumetric efficiency varies during engine operation.  Determination of the actual volumetric efficiency on a real-time basis allows greater accuracy in fuel metering.  The pressure ratio used in the determination of the volumetric efficiency is the ratio of the intake and exhaust pressures or the inverse of this ratio.  The ratio of pressures is combined with a second factor representative of the forces acting upon the air or air/fuel mixture inducted into the engine.  The pressure ratio may be ob-tained without actual measurement of the pressure in the engine's exhaust conduit.

Abstract: ABSTRACT           Image forming methods and apparatus for forming an image, using an image forming sheet which has on an organic substrate a heat-developable image forming layer that is normally non-photosensitive but is rendered photosensitive by preheating prior to exposure and forms therein a latent image by exposure and then provides a visible image by heat development.  An image forming area of the image forming sheet is preheated and heat-developed to obtain the visible image.  In order to prevent an image forming area of the image forming sheet from heat deformation by heating for the preheating or heat development, the image forming area is heated by heating means, holding the opposite side from the image forming layer corresponding to the image forming area in close contact with a flat portion of an image forming area support member in a manner to extend over the entire area of the flat portion, and after the heating, the image forming area is cooled down to a temperature below the glass transition point of the organic substrate, still holding the opposite side from the image forming layer corresponding to the image forming area in close contact with the flat portion of the image forming area support member.  After the cooling, the image forming area support member is brought out of contact with the image forming area.

Abstract: ABSTRACT Soluble coffee is produced by steaming an elongated bed of roasted and ground coffee at atmo-spheric pressure or above and collecting an aromatic flavor condensate.  Thereafter the steamed bed is swept for at least 15 minutes with a gaseous stream having a superficial velocity through the bed in excess of 3 meters/min. in order to entrain and remove liquid acid components.  The coffee is next subjected to aqueous extraction, the extract is then combined with at least a portion of the condensate and dried.  The resulting soluble coffee is much reduced in undesirable acid content compared to soluble coffee obtained from steamed coffee which had not been swept with gas.

Abstract: METHOD AND APPARATUS FOR SETTING A CLAMPING LOAD   ABSTRACT OF THE DISCLOSURE         The clamping preload in a molding machine or the like is set by adjusting the length of tie bars which support two die plates for opening and closing movement and a thrust plate.          A clamping mechanism of given stroke is positioned between the thrust plate and one of the die plates, and operates to close the die plates at one limit of the clamping stroke.  With the clamping mechanism set at its limit and the tie bars set to establish a slight spacing between the die plates, the length of the tie bars is adjusted by means of a drive motor until the die plates are in contact without substantial preload.  The clamping mechanism then opens the die plates and the drive motor is further energized to adjust the length of the tie bars and bring the die plates closer to one another by an amount corresponding to a preselected preload. The adjustment is measured from a high ratio mechanical drive connecting the drive motor to the adjustable tie bars, and the measured adjustment is compared with a desired adjustment corresponding to the preselected  preload to deenergize the drive motor when the desired adjustment is reached.

Abstract: ABSTRACT            This invention relates to a skip or loading flask which has a body defining a storage chamber and a sloping bottom.  A discharge opening is defined in the body adjacent to the sloping bottom, and a door for closing the discharge opening is openable to allow material to be discharged from the chamber.          The body includes at least one pair of opposed walls arranged so that the storage chamber widens downwardly within the body as a wear-reducing factor.  The door may be operable by at least one door-operating mechanism such as over-centre mechanisms, arranged for normally holding the door closed.          For example, over-centre mechanisms may at least partly extend alongside the opposite sides of the body and, in a skip, may be operable by movement of a follower along a cam track to open the door, more complex locking mechanisms thus being avoided.  The door can be pivotable about an axis for closing the discharge opening, and the sloping bottom and the door may then have supporting surfaces meeting at a junction substantially extending along said axis to restrict passage of material between the surfaces.          A loading flask of the invention can be used with a feeder chute located to guide material discharged over the door and having a feeder surface at a steeper slope than the door when the door is in its fully open position.

Abstract: SAFETY BRACE                    ABSTRACT OF THE DISCLOSURE           Provided is a brace for preventing a truck body from falling when raised above its chassis for maintenance, inspection or servicing.  The brace includes a support column, one end of which is pivotally connected to a body longsill and the other end is retained by a release mechanism located on the body for holding the column in riding position.  Provided on the chassis is a retaining means for securely retaining the column when it extends between the body (when raised) and chassis as a brace to prevent the body from falling.  A stop means is provided for limiting the pivot angle of the column.  The brace is installed in supporting position without an operator having to locate any portion of his body under the truck body while raised.  This is accomplished by actuating the release mechanism to release the column.  The body is then raised from remote control location and the column pivots until it abuts its stop mechanism which locates the lower end of the column above the retaining means on the chassis.  Lowering of the body then joins the column and retaining means to form a brace structure which prevents the body from being further lowered.
