Abstract: STRETCHABLE LOAD-RETAINING                    CONVEYOR BELT                 ABSTRACT OF THE DISCLOSURE         A conveyor salt of stretchable elastomeric material reinforced by layers of cords which permit an initial stretching of the belt at installation of at least 5 percent.  Reinforcing cords are positioned in the belt elastomeric material to generate transverse forces during stretching of the belt which results in the interaction of the material of the belt with the cords.  This interaction causes the edge portions of the belt to curl upwardly and form load-retaining walls at the edges.  The belt may have a bottom stretchable portion which is reinforced to resist outside transverse forces resulting from the passage of the belt around a curve.  A top stretchable portion of the belt has edge portions which bend upwardly to form the load-retaining. walls.  The edge portions of the belt may curl suffi-ciently to bring the edges together and they may be connected for enclosing the load on the belt surface.

Abstract: "ENERGY SAVING CHIMNEY CAP ASSEMBLY" ABSTRACT OF THE DISCLOSURE         Even when no fire is burning in a grate, there is a consistent heat loss from the house through the chimney. Attemps have been made to detachably seal the chimney at the upper end thereof but condensation and freezing often occurs in cold climates tending to cause an ice seal to form between the closure plate and the seat thus making it difficult to open when it is desired to use the fireplace. The present device consists of a cap assembly engageable within the upper end of the chimney having a seat on the main body portion and disc or plate secured to a rod mov-able vertically.  It may be actuated from a sealed seat en-gaging position to an open seat disengaging position and the plate is normally maintained open by means of a spring. Actuation is by means of a cable attached to a rod which extends downwardly to the fireplace.  An asbestos seal is provided to reduce icing but also, when closed against pressure of the spring, the disc "oilcans" downwardly so that, when released, the oilcanning action assists in breaking any ice which may have formed on the seal.

Abstract: ABSTRACT OF THE DISCLOSURE      Preferential sulfur dioxide absorption solvents may be buffered with suitable agents, such as alkanolaminium carboxylates, to substantially retard or eliminate the tendency of such solvents to degrade or accumulate non-regenerable salts, particularly sulfates, when loaded with absorbed sulfur dioxide.  A method for employing the buffer as an immiscible aqueous phase as a separate trimming solvent to selectively abso?  residual sulfur dioxide from a gas stream from which the bulk amount of sulfur dioxide is first removed by contact with a trialkyl phosphate solvent is disclosed.  The method permits the trialkyl phosphate solvent to be regenerated and purged of salts at lower energy requirements.

Abstract: ABSTRACT OF THE DISCLOSURE     A hand carriable powered snow removal apparatus having an internal combustion engine power unit removably connected to one end of a tubular boom which supports an elongated drive shaft connected to the engine power takeoff shaft at and to a right angle drive gear unit mounted at the opposite end of the boom. The gear unit includes a housing mounted on the end of the boom and providing a centered drive arrangement for a pair of opposed paddle type impellers mounted on respective ends of an output shaft projecting from opposite sides of the gear housing. A shroud mounted on the gear housing includes an upwardly projecting rear wall and spaced apart lateral side walls partially enclosing the impellers and providing directional control for the snow being discharged from the impellers.          A set of movable guide vanes is mounted on the forward end of the shroud and is adjustable to provide for varying the directional attitude of snow being discharged from the shroud. The interior of the rear wall forms a substantially continuous smooth surface which reduces the tendency for snow to accumulate and clog the normal flow path of the snow being discharged by the impellers. A removable scraper bar is mounted on the lower edge of the shroud and also serves as a skid for the apparatus while it is in operation.          A handle on the power unit and an adjustable handle on the tubular boom provide for handling and maneuvering the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE A valveless pump system having two moving parts con-siting of a cylinder with a piston therein defining a pump chamber. An inlet part communicates with a dip tube which extends into a container and permits the product in the contain-er to pass into the pump chamber. An outlet port allows for the product thus drawn to be dispensed from the pump chamber. The pump is actuated by pressure directed axially on the piston, forcing it into the cylinder. Fitted with a return device the piston is allowed to reciprocate in the cylinder alternating between a suction and compression stroke. During the suction stroke product is drawn into the pump chamber by way of the inlet port while the compression stroke provides for the dis-pensing of the product thus drawn via the outlet port. The system is equipped with passages and channels sufficient to accomplish the operation of drawing and dispensing the product in addition to providing for the venting of the container. The suction stroke provides for air to be drawn through the outlet part from the ambient into the pump chamber, advantageously removing any residual product from the outlet part where this is desirable. In certain applications the air is drawn into the pump chamber to assist in the dispensing of the product during the compression stroke. The introduction of air into the pump chamber also assures the presence of an air pocket therein, thereby maintaining a resiliency in the system thereby preventing piston "hang up". Embodiments of the pump system are disclosed having a vertical pump axis equipped with a verti-cally reciprocal finger actuated button or having either a vertical or horizontal axis with a trigger actuator. Different cylinder and piston configurations are disclosed facilitating commercial applications of the system.

Abstract: Abstract Process for cooling a continuously cast ingot during casting The cooling of a continuously cast ingot as it emerges from the mould, during casting, is carried out by applying coolant directly to the ingot around its circumference. In order to reduce the extent of doming - which occurs to the ingot base when cooling is too strong - the coolant is applied, at least at the start of the drop, to zones via streams of coolant.     The process can be realised in practice particularly simply with an electromagnetic continuous casting mould which has a cooling device featuring a nozzle, with a ring shaped opening (12) for liquid coolant, directed at the surface of the ingot (1). A deflecting sheet (17) with turret shaped tongues separated by openings is provided projecting into the path of the coolant emerging from the ring shaped gap (12). The deflecting sheet (17) is positioned parallel to the main ingot axis and can he moved parallel to that axis.

Abstract: ABSTRACT The threshold level for demodulating an FM signal, for instance a television picture signal, has been improved or lowered by adaptively restricting the bandwidth of the signal using an adaptive bandpass filter, and therefore, the picture quality and/or S/N ratio of the demodulated television signal has been improved.  The adaptive bandpass filter has enough bandwidth when the signal level is sufficiently higher than the threshold level, but is narrow when the signal level is close to or lower than the threshold level. The bandwidth of the adaptive bandpass filter is adjusted according to the total power of the input FM signal and C/N (ratio of the carrier-signal to noise) ratio.  The improvement of the threshold level is almost 2 dB.

Abstract: ABSTRACT OF THE DISCLOSURE      A crystallizing apparatus particularly for use with undercooled melts.  Crystallizing is effected on the cooling conveyor belt in a thick layer.  A precrystallizer comprises at least two rolls arranged above the cooling conveyor and rotating in the same direction.  A shear gap is formed between the rolls.  A melt is applied to an upper-most one of the rolls in a thin layer.  In the course of the path followed by the melt over the rolls, shearing forces are generated within the area of the shear gap, which enhance the nucleation.  A further enhancement of nucleation is obtained by cooling the rolls, so that relatively large volumes of the melt may be crystallized per unit time in the crystallizing apparatus without the need for the addition of supplemental seed crystals to the melt.  The amount of melt in the precrystallizer is very small.
