Abstract: A breading machine has first and second combination battering/breading units positioned in close proximity to each other. Certain features of the invention have utility with machines having only a single battering/breading unit. Each of the combination units has a battering unit for applying a fluent batter to a food product. The battering unit includes a batter reservoir and a battering unit conveyor system for delivering food products from said batter reservoir to a battering unit conveyor discharge section that propels the food product from the battering unit. The combination units also include a breading unit for receiving food product from an associated battering unit. The breading unit includes a breading reservoir and breading unit conveyor system for applying particulate breading to the food product at a breading station by moving breading material from the breading material reservoir and food product coated with the batter to the breading station.

In one embodiment the paper web includes a continuous relatively thinner region and a plurality of discrete relatively thickner regions. The relatively thicker regions are disposed in the plane of the relatively thinner region. The paper web can have a relatively patterned face and a relatively smooth face.

Abstract: A robot for transporting a plurality of wafers from one processing station to another in a batch-type semiconductor device manufacturing process includes a chuck for holding wafers, a spray nozzle for spraying inert gas on the wafers in order to cover them and thereby prevent their contact with the surrounding air, and a supply line for connecting the spray nozzle and an inert gas supply source. The spray nozzle has a plurality of spray openings spaced apart at uniform intervals. The inert gas is sprayed over the wafers from a nozzle that moves with the robot, thereby creating an inert gas environment around the wafers. Accordingly, as the robot moves, water or other particles adhering to the wafers do not contact the surrounding air moving relative thereto. Hence, marks are prevented from being produced on the wafers.

Abstract: In a method and an apparatus for plating a plurality of kinds of works, an unattended route-free vehicle transports the works to a number of processing tanks to immerse the works in the processing tanks. A controller calculates a processing time of the processing tanks and a transporting time needed for the vehicle to transport the works to the processing tanks and renders the vehicle to transport one kind of the works during the immersion-processing of another kind of the works, thereby performing the plating process of a plurality of kinds of works one after another.

Abstract: An improved process is disclosed for deinking waste paper which contains laser, electrostatic, and other non-impact printing toners/inks to produce high quality (high brightness, little to no dirt content) pulp with little or no fiber loss. The process involves attachment of ink particles in the waste paper pulp to a magnetic carrier material with the help of an agglomeration agent followed by removal of the attached ink particles by magnetic separation. The magnetic treatment preferably is conducted at ambient or greater temperature, at neutral to alkaline pH, and at a low pulp consistency. Agglomeration and magnetite addition, followed by exposure of the repulped waste paper to a magnetic field provides near complete ink removal over exposure to the magnetic field without such pretreatment.

Abstract: A pulp dewatering and washing apparatus comprising a pressure vessel in which is contained a table assembly having a foraminous surface, in the form of a conveying belt, on which a pulp slurry is deposited. A differential pressure chamber in the table assembly is vented to a lower pressure location to cause a pressure differential across the pulp slurry to cause dewatering. Also, wash water is deposited on the dewatered pulp in sequential cycles to accomplish washing. A contact plate is provided to press the pulp slurry to aid in dewatering. The conveying belt of the table assembly on which the pulp slurry is deposited is stationary during the dewatering and washing, and then after the pressure differential between the vessel and the pressure differential chamber is reduced to zero, the conveyor belt moves the dewatered and washed slurry to a discharge location.

Abstract: The diaphragm of the electroacoustic transducer is made of a material in which fibers having at least two different radii taken out of wood are mixed together. Two mean radii A and B, among different mean radii of the fibers are set to satisfy the relationship: 0.5.times.A.ltoreq.B.ltoreq.0.5.times.A. By utilizing such a diaphragm, the balance of the density, rigidity, and internal loss of the diaphragm can be improved, and thus the acoustic characteristics of the electroacoustic transducer such as a speaker unit can be improved.

Abstract: In a process for the recovery and re-use of raw materials from paper mill waste sludge, the sludge is subjected to a preliminary cleaning treatment at a relatively low consistency, thickened to a consistency of 10 to 30%, heated to at least 100.degree. C. and then passed through a disperser in the thickened heated state before being passed to a papermachine for re-use. Papermaking fibre from at least one other source is mixed with the sludge before and/or after treatment as just described, so that the final paper product typically contains up to 30% of raw materials recovered from sludge. The action of the disperser is to break up dirt and other debris, and as a result, the recovered raw materials can be re-used in the manufacture of high quality fine papers.

Abstract: An injection device is disclosed for the treatment of wood without the necessity of a rivet-set. The injection device has a deformable elastic body having an internal cavity intended to receive a conical injection head and including an anti-return valve system therein. The upper part of the body has a double wall which consists of an external wall and an internal wall. The external wall absorbs deformations due to the driving-in phase of the injection device. The internal wall insures the nondeformation of the circular ridge of the cavity to guarantee the seal between the conical injection head and the injection device during the injection phase of the treatment product.

Abstract: Process and device for coating hollow objects exhibiting an opening, and beverage cans in particular, in which the hollow objects are immersed completely and with the opening downward in a paint-filled submersion bath, the openings being moved into the vicinity of nozzles for the paint, which are located underneath the surface of the liquid in the submersion bath and which at least partially displace the air trapped in the hollow objects immersed in the submersion bath by means of streams of paint discharging from the nozzles. With this process and device hollow objects can be painted uniformly inside and outside in one step without its being necessary to turn them either to fill them with paint when immersed in the submersion bath or to drain them after their being lifted out of the bath.
