Abstract: ABSTRACT         The invention provides an apparatus and method for monitoring the volume of material loaded into a truck body.          Apparatus is provided for sensing the volume of material held in the truck body and indicating, visually or audibly, when a pre-determined volumetric loading has been accomplished.  Such an indication informs the appropriate personnel that, if the mater-ial being loaded is of high density, loading should be stopped.          Several different embodiments for the sensing apparatus are dis-closed, one of which is a plurality of horizontal holes in the side of the truck body located at a level corresponding to the maximum loading level for a high density material.  A cover plate is provided for covering these holes when not being used as a horizontal sight gauge for monitoring the volume level of the material being loaded.  Each of the plurality of holes includes a mechanism for preventing material flow through the holes when the cover plate is lowered to expose them to view for use as a hori-zontal sight gauge.

Abstract: ABSTRACT       For the seperation of particles, e.g. liquid drops, from a gas stream a vessel with an internal labyrinth is used in general through which the gas is conducted, whereby the particles are thrown out against the walls of the vessel and flow to the bottom of the vessel where they can be collected. Such known arrangements present great flow resistance and do not produce air which is sufficiently clean to be reused and applied under sterile conditions of the type prevailing in aseptic packing machines.      An apparatus for the separation of particles from a gas stream in accordance with the invention is provided with a helical guiding element     and a collar     fitted at the end of the same which is designed so as to have drop-forming elements Consequently, on the one hand a strongly rotating movement is imparted to the air at a relatively low flow resistance, on the other hand it is processed by the drop-forming elements of the collar, which results in high capacity as well as effective separation.

Abstract: ABSTRACT OF THE DISCLOSURE     A gasket of the kind comprising particles of compressed expanded graphite bonded to an apertured reinforcement plate is made by pressing the graphite particles onto the face of the plate without lateral support of those particles at the periphery of the plate, as by pressing between two compressor belts.  In thus dispensing with vertical moulding elements, the method enables a more uniform density of graphite to be obtained over the surface of the plate, and yet leaves the graphite coating at the periphery acceptably uniform with the remainder.          The method is specially applicable to the manufacture of gaskets for the cylinder head of an internal combustion engine.

Granted: 1987-08-04
Abstract: ABSTRACT           A multi-level priority micro-interrupt controller for a micro-program controlled computer handles a plurality of interrupt signals at a plurality of levels of priority, wherein only one interrupt signal for each level of priority may be active at any moment.  When an interrupt occurs which has a higher priority than that of the interrupt currently being handled, the control store address of the next instruct-tion to be executed is stacked and the interrupt handler subroutine for the higher priority interrupt is initiated. When an interrupt occurs which has a lower priority than that of the interrupt currently being handled, it is queued.  After an interrupt has been handled, the stack is popped and execu-tion is resumed at the control store address at the top of the stack.  The control store address of the interrupt handler subroutine for a particular interrupt is decoded from the interrupt signals in two parts, the second part also being used to control the branching to the interrupt handler subroutine.

Abstract: ABSTRACT OF THE DISCLOSURE          This machine can serve as a compressor or motor and, more specifically combines a compressor and a motor to constitute an internal combustion engine with compressed air injection.  A toothed rotor is rotatable in a fluid displacement chamber and in sealing contact with a sealing rotor having peripheral cavities for receiving the teeth of the toothed rotor.  Both rotors are axially curved, so as to better resist differential axial thrust exerted on the same and, therefore, maintaining better sealing contact.          The teeth of the toothed rotor are generally of a hemi-spherical shape to facilitate the provision of effective sealing segments.  When used as an internal combustion engine, a combined fuel injection and ignition device is provided enclosed within a sleeve rotatable within the engine housing, the sleeve having a lateral opening which can be made to selectively register with one of two housing passages opening in two adjacent fluid displacement chambers, with the result that the engine can be reversed by the simple rotation of the ignition device enclosing sleeve.

Abstract: Abstract Aromatic oligomers, in particular arylene ketone and arylene sulfone oligomers, are prepared by reacting an appropriate monomer system in the presence of free Lewis acid and a complex between a Lewis acid, for example, alumi-num trichloride, and a Lewis base, for example, N,N-dimethylformamide, and, optionally, a diluent, such as methylene chloride.  The process is particularly advan-tageous for the preparation of substantially or all para-linked arylene ether ketone oligomers as the presence of the Lewis acid/Lewis base complex markedly reduces alkylation and ensures the substantial absence of ortho substitution. The monomer system can be, for example, a self-reacting monomer such as p-phenoxy-benzoyl chloride or a two-monomer system such as 1,4-diphenoxybenzene and terephthaloyl chloride.
