Patent CA-1076965-A (CA)

Abstract: Abstract The invention provides a device for removing separated components from a layer floating on a carrier liquid towards an overflow, the latter being provided with an upwardly inclined dis-charge surface submerged in the liquid, along which the floating components can be removed from the layer towards the overflow, which device comprises a movable carrier with blades or vanes or the like, which carrier is movable in such a manner that these blades follow a closed trajectory and are moved immersed into the liquid in the direction of the overflow, which device is charac-terized in that this carrier is constructed in such a manner that the closed trajectories of the individual blades only extend over a partial region of the total displacement path of the supernatant layer.  In particular the closed trajectory of an individual blade or group of blades is or can be adapted to the displacement re-quirements of the layer in the respective region.  Such a device has improved versatility and separating ability for floating lay-ers over conventional separators which may cause undesirable dis-turbances in the floating layer or discharge floating matter in insufficient concentration.

Abstract: ABSTRACT OF THE DISCLOSURE An article of luggage which includes a luggage case having a peripheral side wall which is made of a flexible material.  In order to impart some degree of rigidity to this flexible side wall, a frame structure is situated in the interior of the luggage case and extends along the inner surface of the side wall thereof.  This frame structure has at each of a plurality of regions thereof a pair of frame portions which are substantially rigid and which terminate in free ends which are spaced from and directed toward each other.  This frame structure also includes at each of the above regions thereof a spring construction which is operatively connected with the frame portions for acting on the latter to urge them apart from each other so as to tend to increase the distance between the free ends thereof.  Thus, the substantially rigid frame portions are pressed by the spring means against the inner surface of the side wall of the luggage casing to impart a certain degree of rigidity to the side wall.  At the same time, because of the presence of this spring construction it is possible for the luggage casing to resiliently yield when encountering impacts, crushing forces, or the like, with the spring construction returning the parts to their original condition when these impacts, crushing forces, and the like no longer act on the article of luggage.

Abstract: ANTI-CAVITATION AND PRESSURE MODULATING RELIEF VALVE FOR CONTROLLING HYDRAULIC CYLINDERS                     A B S T R A C T      A construction vehicle has a work implement, such as a bucket-carrying boom, pivotally mounted thereon to be raised and lowered by one or more double-acting hydraulic cylinders.  A directional control valve is conditioned to selectively communicate pressurized fluid to the rod end of each cylinder, for example, through a check valve.  When the fluid pressure in the rod end of the cylinder exceeds a pre-determined level, a pilot signal will be communicated to a modulating valve which will open to closely control and modulate the flow of the fluid exhausted from the head end of the cylinder.  A pilot relief valve is interconnected between the head end of the cylinder and the modulating valve to cooperate therewith to relieve excessive fluid pressures.          The above system is duplicated for selectively pressurizing the head end of the cylinder and for exhausting the rod end thereof.

Abstract: METHOD AND DEVICE FOR PRODUCING HOLLOW ARTICLES HAVING FLANGES              ABSTRACT OF THE DISCLOSURE      A material to be press-formed is confined in a space having a contour corresponding to the outer contour of the flange part of an article to be produced and is pressed between a member having a through hole correspond-ing to the outer contour of the hollow main part of the article and another member holding slidably a mandrel having an outer contour corresponding to the inner con-tour of the internal bore of the hollow article, the mandrel being simultaneously projected into the through hole of the first member.  By the pressing action, the peripheral part of the material is formed into the flange part of the article while an inward flow of the material is caused, thereby elevating the surface of the material in the through hole and forming a recess in the opposite side surface of the material.  The mandrel projected simultaneously with the pressing action aids the materi-al flow and the forming of the hollow main part of the article with minimal force.  Modifications for producing articles having various configurations and for continuous production thereof are also disclosed.

Abstract: FILTER SYSTEM FOR FRYING APPARATUS          ABSTRACT Frying apparatus including a fry pot and a filter system operable during a cleaning cycle for dislodging food particles which cling to the fry pot and for removing food particles suspended in the cooking oil is disclosed. The filter system includes a shower apparatus which discharges jets of cooking oil along the interior side surfaces of the fry pot to dislodge food particles clinging thereto. The cooking oil is strained through a filter into a drain pot and means are provided for pumping the filtered cooking oil back to the fry pot where it is discharged through the shower apparatus. Food particles are continuously separated from the cooking oil as it is conveyed from the fry pot through the filter into the drain pot. In a preferred embodiment a control circuit is provided for automatically turning off the fry pot when the cooking oil is drained during the filter cycle. The control circuit includes means for locking up the fry pot heating system in the off condition when the draining operation occurs. Reset is accomplished by first turning the fry pot off and then back on to insure that the operator exercises positive control before the heating system is energized.

The input shaft also drives the carrier of the third planetary assembly.  A brake grounds the first carrier in the first range and in reverse and causes drive to be delivered to the output through the first ring gear in a hydrostatic mode. The carrier of the third planetary assembly drives the ring gear of the second planetary assembly, and a first clutching means connects the second carrier with the output in a second range, the brake for grounding the first carrier then being released. A second clutching means enables the third ring gear to drive the output shaft in a third range.
