Abstract: Crank-chamber precompression type two cycle engines having scavenging ports connected with the crank-chamber through scavenging passages. An air supply passage is connected through a reed type check valve with at least one of the scavenging passages at the upper portion thereof so that air is introduced into the scavenging passage in the ascending stroke of piston movement and discharged into the combustion chamber in the descending stroke of the piston movement to effect scavenging. The air passage is provided with a control valve which is interconnected with the engine throttle valve so that the amount of air supply through the air passage can be controlled in accordance with the load condition of the engine operation.

Abstract: A barrier for water carried pollutants comprises a series of end to end connectable boom sections containing a flotable material; fluid impervious connectors for the ends of the boom sections; flexible draft members and associated connectors for maintaining the integrity of the boom if it becomes necessary to replace one or more of the boom sections, and means associated with the flexible draft members and the fluid impervious connectors whereby separating stresses are minimized at the end connections of the boom sections.

Abstract: Decorative knitted fabrics have a basic weft knit structure with patterned effects produced by a warp yarn loops of which cover selected loops of weft yarn so as to be visible on the face of the fabric. The fabrics are produced by feeding warp yarns to selected needles of a straight bar knitting machine in addition to the normal weft yarn and controlling the tension of the yarn such that the warp yarn loops cover the corresponding weft yarn loops in the desired manner. To ensure the desired structure, it is preferred that the tension in the warp yarn should be relatively high when the yarn is wrapped round the selected needles but relatively low when the needles execute their knitting motion. Apparatus for producing these fabrics includes warp yarn guides which can be moved to and fro in front and behind the knitting needles and moved sideways past one or more needle positions. The warp guides can be swung upwards to clear the needles during fashioning movements.

Abstract: An upholstery fabric, suitable for providing the sole body-supporting surface in a seat construction with a lightweight, for example tubular, frame, comprises a rigid, knitted base fabric and, interengaged therewith, a fabric surface formed from textile yarns having flame retardant properties. The fabric is preferably warp knitted and the base fabric has a rigid net structure. A decorative surface yarn is preferably interlaced at every course with the base fabric.

Abstract: A barrier for water carried pollutants comprises a series of end to end connectable boom sections containing a floatable material which may comprise an oleophilic-hydrophobic-lighter than water composition which will selectively absorb hydrocarbons; fluid impervious connectors for the ends of the boom sections and flexible draft members and associated connectors for maintaining the integrity of the boom if it becomes necessary to replace one or more of the boom sections.

Abstract: A process and apparatus for continuous removal of liquids from sludges. The apparatus includes an endless driven lower pervious belt and an endless driven upper impervious belt. The impervious belt is supported by an upper frame positioned above a fixed lower frame member by spring-loaded, adjustable hydraulic cylinders. The two belts are driven at different speeds to provide continuous shear on sludge pressed between the belts. Each belt is supported on a plurality of horizontally spaced rollers with the rollers for the upper belt and the rollers for the lower belt being longitudinally offset from each other. The horizontal roller spacing from the point of contact of the upper belt to the sludge as it is fed in between the belts is of a diminishing progression which may be arithmetic, geometric, or a combination thereof from the point of contact of the upper belt on the sludge to the discharge end.

Abstract: Amber glass is made by melting a soda-lime glass-forming batch in which at least 1 percent of the silica content is provided by lignite fly ash.

Abstract: A high freeboard barrier for water carried pollutants includes a series of end to end connectable tubular boom sections with each boom section including an upstanding fin and a depending skirt, and further fabric means extending from at least below the water line to substantially above the fin to thereby increase the freeboard of the barrier. The fabric may be fireproof to reduce oil spill fire damage to the barrier. The fabric means may be of the type which extends the length of the skirt or substantially therebelow and the fabric means may be of the add-on type for use with existing barriers.

Abstract: A sheet holder attachment is used with a sheet holder for a counter for counting sheets and comprises a base member, a keep member pivotably mounted on said base member and spring means for urging said keep member toward said base member to hold a stack of small sheets to be counted on said base member. The base member has a stand portion for supporting the lower end of the sheet stack and abutment members adapted to engage the rear end of the sheet stack.

Abstract: A heat-power engine and system using a condensable vapor as the working fluid has a cylinder with a piston operating therein characterized in that the heat input communicates with the swept volume of the engine in a zone comprising the clearance volume of the cylinder at the top dead center of the piston.

Abstract: Shock absorbing strut assembly comprising a telescopically extensible strut having therein an oil chamber of variable volume, a pressure accumulator comprising a spherical housing and a partition member provided in the housing and dividing the interior of the housing into two chambers, each of the chamber being divided by a flexible diaphragm into an oil compartment connected with said oil chamber and a gas compartment, the gas compartments being charged with gas of different pressures.

Abstract: A barrier for water carried pollutants consists of a series of end-to-end connected boom sections with each boom section including a tubular sleeve portion containing flotation means and a depending skirt. The entire series of boom sections are connected to one or a pair of flexible draft members which are connected to the booms at spaced points by connector assemblies comprising this invention.

Abstract: A supporting framework for heat exchange surfaces for atmospheric cooling towers includes a plurality of primary generally vertically directed support members hingedly interconnected and further support members connected to the primary support members via elastic members having a high modulus of compression and a low modulus of elasticity relative to the elements forming the framework.

Abstract: In an apparatus for constructing high-rising, poured concrete walls, pairs of spaced-apart, upright supports are preliminarily mounted on a foundation and then detachably attached to both sides of at least a partially hardened level of concrete wall and at intervals along the length of the wall for repeated, upward, step-wise use as the wall is being formed; a plurality of carriages are mounted on adjacent supports along both sides of the wall for continuous upward movement as the wall is being cast, and adjustable concrete shaping assemblies are mounted on the carriages. Each assembly opposing a similar assembly to define a continuous mold into which new concrete is poured on top of previously poured concrete to form the wall.

Abstract: A device for detecting stacks of coins for use in a coins-packaging machine adapted to wrap each stack of a predetermined number of coins with wrapping paper, said device comprising a stacking cylinder of an electrically insulating material for receiving coins supplied through the upper inlet thereof and stacking the coins thus supplied face to face relation each other to form therein a stack of predetermined number of coins, an electrically conductive bottom plate disposed adjacent the lower open end of said stacking cylinder and adapted to support the stack of coins from the lower end and be removed therefrom for enabling the stack of coins to be discharged from the stacking cylinder into the next stage for wrapping, an electrode of cylindrical shape formed as part of inner wall of said stacking cylinder at a height of a little more distance than the height of said stack of coins from the lower end thereof, a relay and an electric power source therefor connected in series relation between said electrode and
