Abstract: ABSTRACT OF THE DISCLOSURE         Lubrication system includes lubricant reser-voir that contains an extrudable base material impreg-nated with lubricant, such as oil.  Motor parts, including the reservoir defining parts, are readily assembled with one another and retaining means is provided that permits the efficient transfer of oil to extrudable base material, but prevents inadvertent movement of base material away from a predetermined locale in reservoir.  In one illustrated form, such means are in the form of a plastic member or basket having perfora-tions therein of a size to restrict the movement of extrudable base material therepast and yet promote the movement of oil into the predetermined locale.          In another form a retainer member is fabricated from a lanced and expanded metallic material that forms a perforated base material retainer or basket.  Retainer may be collapsed to permit accommodation thereof in reservoirs of various lengths, and reduce need to stock differently sized retainers for machines having different reservoir dimensions.  Method includes extruding material quickly through a plurality of extrusion openings, so as to reduce tendency to form air pockets or voids within reservoir and reduce filling time;  and restricting free flow or movement of the extruded material with a perforated or foraminous wall.

Abstract: METHOD AND APPARATUS FOR GRINDING A WORKPIECE            Abstract of the Disclosure An improved grinding machine includes a grinding wheel which is moved along a path extending at an acute angle to the axis of rotation of a workpiece.  The workpiece is movable along its axis of rotation.  During plunge grinding operations, the workpiece can be reciprocated along its axis of rotation.  During traverse grinding operations, it is necessary to com-pensate for the acute angle of the path along which the grinding wheel is moved relative to the axis of rotation of the workpiece.  This may be done between traverse grind strokes by initiating movement of the grinding wheel toward the workpiece from a position in which the edge surface of the grinding wheel is offset from the plane of a radially extending shoulder surface. Upon completion of a grinding operation, the wheel is retracted to a clear point.  Different clear points are used so that the grinding wheel is retracted to only the extent necessary when finishing portions of a workpiece having different diameters.  The position of an edge surface of the grinding wheel along the axis of rotation of the workpiece is indicated by data stored in a Z-axis register.  Data corresponding to the distance a face surface on the grinding wheel is spaced from the axis of rotation of the workpiece is stored in an X-axis register.  The data stored in both registers is changed when the grinding wheel is moved toward and away from the workpiece along the path which extends at an acute angle to the axis of rotation of the workpiece. However, the data in only the Z-axis register is changed when the workpiece is moved along its axis of rotation relative to the grinding wheel.  The data in the Z-axis register is adjusted to compensate for the distance which a reference surface on the workpiece is offset from a zero datum position during an initial workpiece locating operation.  To reduce the likelihood of wheel breakage, operation of the grinding machine is automatically inter-rupted when the current required to drive the grinding wheel exceeds a relatively low predetermined amount during high speed positioning movements of either the grinding wheel or the workpiece.  If the current required to drive  the grinding wheel exceeds a rated operating load by a predetermined amount during a grinding operation, the grinding operation is also interrupt-ed.  Fine and coarse pulse generators are provided in association with drive shafts for moving the grinding wheel and the workpiece.  The outputs from the pulse generators are compared and if there is a predetermined difference in the outputs of the fine and coarse pulse generators associated with a particular drive shaft due to a malfunctioning of the grinding machine, operation of the grinding machine is interrupted.

The improved system can be quickly assembled, disassembled, rearranged and newly assembled in different panel order without the necessity of taking the panels out of their frames.  Multi-ple panels are joined  together by means of elongate vertical frames and center posts having reciprocally mating splines and keyways which freely move longitudinally such that the center post can be slipped out, the panels rearranged and the center post put back in to position.  The stability of the system is secured by providing a temporary removable insert in the keyways carrying an elastomeric material which is expanded to frictionally engage the side walls of the keyways.  The elastomeric material can be reversably con-tracted to release the sidewalls.

Abstract: ABSTRACT OF THE DISCLOSURE             An internal combustion engine having a cylinder with a reciprocable piston operable to compress air on its upstroke within the cylinder.  The cylinder communicates via a passage with a main combustion chamber and a subsidiary combustion chamber communicates with a chamber via a passageway.  A reciprocable valve is provided operable to selectively block communication between the two chambers.  Fuel is injected into the subsidiary chamber during the compression stroke of the engine, the chambers then being in communication.  Before top dead centre the valve is operated to block communication between the chambers with compression continuing thereafter in the main chamber.  Around top dead centre additional fuel injection into the subsidiary chamber is begun, the air fuel mixture in the subsidiary chamber is then ignited and the valve opened to cause ignited fuel in the subsidiary chamber to pass-along a passageway to ignite the air-fuel mixture in the main chamber.
