Abstract: ABSTRACT OF THE DISLCOSURE         A tipping adapter permits a cargo container, which is suspended from a hoisting device, such as a gantry cantilever crane, to be selectively tipped about an axis extending longi-tudinally through the container so that bulk material, such as coal, grain, etc., may be tipped from the container into a ship's hold or other receiving space.  The adapter includes a drive support frame which connects to the crane or a crane-supported container spreader at the connection points normally used in connecting the container to the spreader.  A pivotal frame connects to a container in the same manner in which the spreader connects to the container.  The drive support and pivotal frames are pivotally engaged so that one or more drive motors, mounted on the drive support frame, can be used to selectively pivot the pivotal frame and thereby tip the con-tainer.  Controls are placed at the crane control panel to permit selective container engagement and tipping, and inter-locks are provided to prevent tipping of the container before it is properly engaged.

Abstract: Abstract:    A semiconductor device has a first semiconductor layer and a second semiconductor layer smaller in forbidden band gap than the first layer.  These layers are arranged to form a heterojunction.  There is a first electrode for controlling carriers generated at least in the vicinity of the heterojunction interface, and at least two further electrodes.  The second layer is located between the first layer and the first electrode for controlling the carriers.          Both the first and second layers contain an impurity at a concentration of at most 1015cm-3, and an impurity identical in conductivity type to the carriers is contained at a concentration of at least 1016cm-3 in regions located between the further electrodes and a region where the carriers are generated, so as to electrically connect the further electrodes and the carriers generated in the vicinity of the heterojunction interface under the first electrode for controlling the carriers.  Elements of both the enhancement and depletion modes can thus be readily separately fabricated in the same integrated circuit.          The structure also simplifies manufacture.

Abstract: ABSTRACT OF THE DISCLOSURE     The plastic magnet composition provided by the inven-tion comprises a thermoplastic resin as a binder and a pow-der of a metallic or alloy-type magnet which is coated on the particle surface with a phosphorus-containing compound having at least one phosphorus-to-oxygen linkage in a mole-cule such as phosphoric acid and related compounds. By vir-tue of the surface coating, the magnet powder is freed from the degradation by air oxidation and the danger of ignition in the molding process so that plastic magnets of high per-formance can be readily manufactured with safety. The ad-vantages of the coating layer are further increased when the coating layer is formed of a combination of the phosphorus-containing compound and an organic dye compound. An over-coating on the thus coated magnet powder with an organo-polysiloxane has an effect of increased lubricity.

Abstract: A B S T R A C T         Method and apparatus for monitoring and controlling production line filling of receptacles with a predetermined weight of variable density material.      Each filling station comprises a balance (36) and a piston and cylinder volumetric dispenser (37).  The piston rod (33) is actuated by a cam (34) which optionally includes a portion (341) which is adjustable.  Resilient means (40) are interposed between the cam and the piston.  While a receptacle (39) is engaged in a filling station the following operations take place in succession: the empty receptacle is weighed and at the same time the volumetric dispenser is filled with slightly more material than is to be dispensed; the material in the volumetric dispenser (37) is then transferred to the receptacle (39) and the receptacle is continuously weighed until it has received the set weight of material.  The outlet from the dispenser is then closed, thus jamming its piston before it reaches the end of its stroke.  The resulting forces are absorbed by the resilient means.  Optionally, the amount material which is admitted to the dispenser prior to each filling operation is adjusted by acting on the said adjustable portion of the cam, to ensure that receptacle filling is stopped in the vicinity of a predetermined point on the cam or of the piston stroke.

Abstract: CONTROL SYSTEM FOR A PROCESS     ABSTRACT OF THE DISCLOSURE         A perturbed feedback control system for a process.      Inputs to the process include a feed stream and a manipulated variable.  The manipulated variable is controlled by a feed-back controller.  Measurements of a parameter measured "downstream" of the process are taken periodically and fed back to the controller.  The feedback controller generates a control response on the basis of a comparison of the two most recent values of the downstream parameter.  The comparison is made by calculating a perturbed set point which includes the values of the downstream parameter taken at the two most recent sampling periods.  In a specific embodiment, the per-turbed set point also includes measurements of the most recent and receding values of the manipulated variable.  A control response is applied to the manipulated variable by the feedback controller based on the value of the perturbed set point.  The control system has been applied to optimize the feed rate of chemicals for sludge dewatering on a twin belt filter press.

Abstract: MIXING OXYGEN GAS WITH MEDIUM CONSISTENCY PULP IN A PUMP DISCHARGE                 ABSTRACT OF THE DISCLOSURE          Oxygen delignification of paper pulp (comminuted cellulosic material in a slurry) at medium consistency (i.e., about 6-18%) is practiced without the necessity of a separate mixer.  The pulp is drawn into the inlet of a fluidizing centrifugal pump capable of pumping medium consistency pulp. The pump typically has a vacuum system associated with it for effecting degassing of the pulp.  As the pulp is pumped out of the pump outlet, oxygen gas is added to the pulp.  This is accomplished utilizing a shear plate having a central opening and one or more radial bores, oxygen being introduced under pressure into the bores to pass into the pulp flowing through the plate central opening.  A tube may be disposed in the bore(s) and have an oxygen permeable portion (such as a porous stone or sintered metal) extending into the central opening in the plate, the oxygen being introduced in the form of very small bubbles by the oxygen permeable portion.
