Abstract: A substantially hemispherical bowl is provided with a handle. An inner boat-shaped receptacle, which has a generally V-shaped cross-section and tapers toward each of its ends, is supported by the bowl in a generally inverted position relative to the bowl, with one side of the boat-shaped receptacle generally conforming to and slightly spaced from the inner surface of the bowl at one side of the bowl. The space between said side of the boat-shaped receptacle and the inner surface of the bowl forms a pouring passage extending from an inlet slot between the edge of such receptacle and the inner surface of the bowl to a discharge slot between the edge of the bowl and the bottom of such receptacle.

Abstract: The invention provides a marine drive unit of the through or over transom drive type, in which the power leg is pivoted on the axis of a transverse shaft at the heart of the drive transmission so that the power leg can tilt upwardly and rearwardly about that axis whilst the drive gears remain meshed, without utilising any universal joints.

Abstract: A chamber which forms a material inlet and an exhaust gas outlet at one end of a rotary kiln has an inclined bottom arranged to cause preheated fine material deposited thereon to slide by gravity into the end of the rotary kiln. A dense stream of fine granular material is deposited on such inclined surface, and fuel in finely divided form is introduced into the dense stream of material flowing down the inclined surface to cause the fuel to become intimately mixed with the material. Gas is discharged from the kiln in contact with the stream of material as such a velocity as to entrain a substantial proportion of such stream, the temperature and composition of the gas being such as to cause combustion of the fuel mixed with the entrained material.

Means are provided for heating said depressed central surface and thereby heating food receptacles supported thereon. A removable cover substantially fills the depressed central portion of said support to form with the surrounding portion of said support a substantially level unheated surface for supporting food receptacles. Means are provided for spacing said cover from said depressed central surface.

Abstract: A warp tension controller for a loom comprises a warp tension sensor for generating a first signal which is a measure of the warp tension, a source of a reference signal, and means for comparing said signals and producing an output signal representing deviation of said first signal from said reference signal. An operational amplifier has an inverting input connected to receive said output signal, and has an output connected to means for adjusting the warp tension. A feedback circuit connected between said input and said output of said amplifier comprises a resistor in parallel to an integrating capacitor.

A trough-like yarn-storing means is provided immediately above and substantially coextensive with said conduit, and said blowing nozzle is spaced from and directed toward the end of said trough-like means, the axis of said nozzle extending just above the level of said conduit and at the level of said trough-like means.

Abstract: The invention provides a bin for household waste having a lid which is counterweighted or spring urged so as to be normally held in a closed position, and with catch means arranged so as to engage the lid when it is swung to an open position and hold the lid in the open position; release means are provided to disengage the catch means and allow the lid to swing to the closed position again.

Abstract: A sheet handling device, especially for stacking sheets, includes overhead conveyor belts with a suction chamber to hold sheets against their undersides and mechanism for displacing the sheets from the belts onto a table. This mechanism includes a set of fingers which, as well as being displaceable through the plane of the belts, are also displaceable in the direction of sheet feed to enable them to engage the sheets while travelling in the same direction at substantially the same speed and thereafter slow down the sheets and displace them towards the table.

Abstract: A plurality of parallel strands comprise chain links which are articulately connected together by grate pins that extend transversely over the entire width of the grate. Rod-like holding members are carried on the chain links and extend substantially parallel to the grate pins. Assemblies of individual support bars have upper edges higher than the chain links, each support bar having two recesses to receive two rod-like holding members. Each assembly of support bars extends substantially between the longitudinal centers of two chain links and is supported by a separate pair of rod-like holding members, for receiving material deposited on the travelling grate chain, and comprises slots for the passage of treatment gas. Each pair of rod-like holding members is interrupted at an intermediate point to provide a gap for insertion and removal of the support bars.

Abstract: Leads electrically connected to the respective terminal portions of coiled wires in a core-type transformer are each provided with a flange on the insulating covering. A set of lugs formed on each of two opposite ends of a coil cover or of a coil bobbin have first grooves in spaced side-by-side relationship for receiving parts of the leads and second grooves arranged crosswise with the respective first grooves for receiving their flanges. A pair of lead covers are snapped into position to enclose the parts of the leads together with the flanges thereon and their connections to the terminal portions of the coiled wires, in such a manner that the leads can be positively retained in position in the respective grooves.

Abstract: A worm drive hose clip comprises a housing, a band having one end secured to the housing and the other end passed through the housing, and a screw which is effectively journalled in the housing and held axially captive therein. Teeth are formed on one face of the band for engagement with the screw, each of which has a crest which is concave along a central portion of its length extending transversely of the band. The root-to-crest height of the central portion of each tooth increases toward each end of said central portion of the crest.

Abstract: A power feed chain has two chain bands and a plurality of connecting struts. The strut construction resists twisting, so as to hold the two chain bands parallel to one another and in longitudinal alignment. It is in the form of a lightweight but rigid grid, comprising two cross-ties consisting of strips of flat material arranged in parallel planes, and a plurality of spacers of flat material which extend between the cross-ties and are arranged in parallel planes that are perpendicular to the planes of the cross-ties. Each spacer has in each of its long sides a relatively deep notch which has parallel sides and which fits around one of the flat cross-ties, so that the spacers and cross-ties form a rigid torsion-resistant grid frame.

Abstract: The invention provides a gas tap particuarly intended to be made of aluminium, using an axially movable plunger to control flow, in which the tip of the plunger is modified for low rate flow control, by providing a low rate flow passage in the tip of the plunger.

Abstract: The shaft cooler comprises a plurality of power-driven adjacent horizontal hollow perforated comminuting rolls. An upper section of the shaft cooler is adapted to hold a layer of material from 50 to 100 cm. deep above the rolls. Cooling air is supplied to the interior of each roll to cause it to be discharged into such layer of material. An aftercooling section below the rolls is provided with means for indirect cooling of the comminuted material and has a depth which is several times that of said layer.

Abstract: The blow gun comprises a hollow body having an inlet for compressed air at one end of the body. A tube extending from the other end of the body has a closed end mounted to swivel in the body, and has a radial port leading from the interior to the exterior of the tube adjacent to the closed end of the tube. A cap carried by the closed end of the tube is radially spaced from the periphery of the tube and shrouds the port. A seal is located in the body, surrounding the tube, on which the cap normally seats to prevent air from entering the port, but from which one side of the cap can be separated by swinging the tube out of axial alignment with the body, to admit air to the port. A nozzle fixed on the outer end of the tube has a Venturi passage extending outward from the tube, the inner end of such passage being radially spaced from the tube and having ports arranged laterally of the tube which act as inlets when air is discharged through the nozzle and as outlets when the nozzle is obstructed.
