Abstract: TALL LENGTH SPLICE IN A MOVING WEB                Abstract of the Disclosure A method and apparatus are provided for forming a zero tail length splice between a new roll of web material (26) and an expiring roll (24) without interrupting contin-uous movement of the web (W).  The method includes providing a splicing strip (60) adhesively secured to the leading edge (62) of the new roll (26) and releasably secured to the surface of the new roll (26) so that it can be rotated with-out unwinding until it is spliced to the moving web (W) of the expiring roll (24), placing a marker (80) on the circum-ference of the new roll (26), which marker (80) is located a predetermined distance ahead of the leading edge (62) of the new roll in a position to be sensed by a sensing device (162) as the roll (26) is rotated adjacent the moving web (W), sensing the location of the new roll (26) relative to the surface of the moving web (W) as it is brought into close proximity with the moving web (W) and stopping its movement so that the roll (26) is held in the desired position just above the surface of the moving web (W), bringing the new roll (26) up to a rotational speed so that its surface speed matches the surface speed of the moving web (W), forcing the moving web (W) into engagement with the rotating new roll (26) at the point of closest proximity therebetween, after the leading edge on the new roll (26) has passed the point of closest proximity as determined by the sensing device(162), noting the passing of the marker (80), and then further activating a cutting means (102) upon the second passing of the marker (80), for severing the moving web (W) at a distance equal to the distance along the circumference of the new roll (26) from the leading edge (62) to the point of closest proximity between the new roll (26) and the moving web (W) so that substan-tially a zero tail length splice is formed when the splicing strip (60) adhesively engages the surface of the moving web (W) adjacent the tail end (168) thereof.

Abstract: A B S T R A C T     A conveyor belt cover for steep conveyance of dusty material having two flexible conveyor belts spaced apart from each other and running along the conveyor path as carrier belt and cover belt.  Each belt has at its longitudinal edge flexible closure strips which become engaged in pairs in the conveyor path to form a closed box-shaped conveyor space and which become disengaged at return locations of the cover belt by a lateral tilting of the closure strips of the cover belt.          The latter are disposed at the outside with respect to the closure strips of the carrier belt.  The closure strips of both conveyor belts have waved vertically orientated ridges with each ridge being of the same height with the ridges of one closure strip being laterally offset from those of the other such that the ridges are disposed beside each other at a small transverse spacing in pairs along the conveyor path.  Each waved ridge has profile knobs at the wave crests disposed at the outer side in the case of the carrier belt and at the inner side in the case of the cover belt.  The knobs are arranged in one or more rows in parallel with the conveyor belt and at such vertical spacing from the conveyor belt that they contact each other in rows at least at their respective undersides facing the conveyor belt.

Abstract: Abstract of Disclosure:            Combustion apparatus for burning waste oils of various viscosities with high combustion efficiency and which can meet  strict  polution regulations comprises primary and secondary combustion chambers with the secondary combust-ion  chamber  located above the primary combustion chamber and the primary combustion chamber located within an outer housing so as to define between the outer housing and the primary combustion chamber a plenum space. An air blower delivers air to the plenum space which feeds air into the primary combustion chamber through air inlet openings in its side wall. The primary combustion chamber has a burner bowl provided at its base and a burner ring disposed above the burner bowl. Oil is supplied at a constant rate to the burner bowl via a positive displacement pump. The burner ring features a central aperture and two concentrically disposed rings of orifices with the orifices of the outer ring being of larger diameter than the orifices of the inner ring. The air inlet openings in the sidewall of the primary combustion chamber comprise a first set located below the burner ring and a second set located adjacent the top edge of the primary combustion chamber above the burner ring. The second set of air inlet openings are preferably relatively smaller and more numerous than the first set. In operation the oil supplied to the burner bowl vaporizes and the flame pattern produced by the burner ring cooperates with the arrangement of air inlet openings to produce stable burning conditions for a wide variety of fuels.

Abstract: 9D-HR-13591-Griffin et al ABSTRACT OF THE DISCLOSURE           A refrigerator having a freezer compartment on top and a fresh food compartment below with all air duct connecting the two compartments.  A temperature control system and method of controlling is provided and includes a temperature sensing element located at the top of the fresh food compartment and shielded from the stream of cold air being directed into the fresh food compartment.  The temperature sensing element changes the temperature in both the freezer and fresh food compartments without changing the constant ratio of those respective compartment temperatures,  An air flow assembly divides the cold air entering the fresh food compartment through the connecting air duct between the top of the compartment and the bottom.  The air flow control assembly is arranged to divide the cold air stream such that the ratio of the difference in the freezer and fresh food compartment temperatures is changed.  By this air flow system and method, the interaction between the cold air flow control and the temperature sensing element provides that the temperature in the freezer compartment may be adjusted up or down while the fresh food compartment temperature remains relatively constant.

Abstract: 1934-305a ABSTRACT OF THE DISCLOSURE             Shredded tobacco is supplied from a storage reservoir to one or more cigarette making machines by way of discrete pneumatic conveying pipes.  The reservoir receives fresh tobacco at regular or irregular intervals so that the quantity of tobacco in its interior is constant.  The contents of the reservoir are maintained in suspension so that at least the major part of the supply of tobacco shreds forms a fluidized bed which is located directly below the intakes of the conveying pipes.  When a machine requires a batch of tobacco shreds, the respective pipe is connected to a suction generating device so that it draws air from the region between the underside of the fluidized bed and the upper side of the bottom wall of the reservoir whereby the ascending current of air entrains tobacco particles directly from the fluidized bed.        The supply of tobacco in the reservoir can be converted into a fluidized bed by mechanically agitating the reservoir so that the shreds move up and down and/or by causing a plurality of streamlets of compressed air to rise through perforations in the bottom wall of the reservoir.  The latter may have a circular, semicircular or polygonal cross-sectional outline.

Abstract: Abstract of the Disclosure A method of cleaning a drying wire of a paper making machine by means of at least one pressurized water jet directed against the surface of the wire by means of a nozzle. The nozzle is supplied with water under a pressure higher than normal water pipe pressure, preferably a pressure of 3-9 MPa. The increased pressure of the water jet reduces the amount of water remaining in the wire due to the increase of the amount of water passing through the wire. Con-sequently the increased pressure of the water jet makes it possible to clean the drying wire during production and web formation.
