Abstract: A direct suction hermetic compressor assembly is disclosed including a hermetically sealed housing having enclosed therein a compressor mechanism discharging compressed gas refrigerant into the interior of the housing, thereby creating a high pressure housing. The compressor mechanism includes a crankcase defining a suction cavity into which low pressure suction gas is directly introduced. Bearings in the crankcase communicate between the housing interior and the suction cavity, and rotatably support a crankshaft. Annular seals received within grooves in the crankshaft bear against the bearings and are actuated and lubricated by oil fed from within the grooves to prevent high to low pressure gas leakage and to facilitate bearing lubrication. A scotch yoke mechanism operably couples a plurality of radially disposed pistons to a crankshaft eccentric portion within the suction cavity. Oil ducts open onto the loaded surface of the eccentric to limit oil leakage into the suction cavity.

Abstract: A suction accumulator for the compressor of a refrigeration system is disclosed in which a vertical fluid storage vessel comprises a cylindrical central member and a lower end cap. A disk-shaped dirt trap baffle member includes at its outer periphery a plurality of circumferentially spaced tabs that are clamped between the central housing member and lower end cap. Circumferentially intermediate the tabs are gaps through which liquid refrigerant flows from an active zone above the baffle to a quiet zone therebelow. Within the quiet zone, liquid refrigerant flows from a radially outer region to a radially inner region along a tortuous flow path created by a vertically extending wall comprising a portion of the baffle member. A bleed-through orifice in a gaseous refrigerant flow conduit siphons liquid refrigerant from the radially inner region into the gaseous flow path.

Abstract: A four-stroke piston engine in which air is drawn into a cylinder while rotary motion about the cylinder axis is imparted to the air. Fuel may be blown/injected into the air during its rotation in the cylinder while the fuel supply is located on the axis of the cylinder and supplies at least one jet of fuel directed radially outwardly and which jet of fuel in cooperation with the rotating air forms at least one helical stream of mixture within the cylinder, preferably during the compression stroke, which is transformed into a coherent mixture zone enclosed by a ring of air upon completion of compression. The piston may have a recess when the piston approaches top dead center so that an enriched zone is formed in the lower region of the compression space which can be ignited by electrodes disposed in said lower region of the compression space.

Abstract: A mounting system for mounting a face guard on a football helmet, wherein the face guard is able to pivot about a horizontal axis about the top portion of the helmet. The improved mounting arrangement includes a pair of straps in the form of loops which enclose wire segments of the face guard. The straps are mounted to be in tension when the face guard encounters a frontal force. The straps are comprised of a resilient polyurethane material and are dimensioned so that most of the shock force encountered by the face guard due to blows thereon is absorbed by the tension mounted straps. The straps include a tapered end portion and an enlarged neck portion to provide sufficient resiliency yet sufficient rigidity to protect the player and to prevent the face guard from being permanently distorted. The head portions of the straps are dimensioned so that the face guard, in case of an injury to the player, can be pivoted past the head portions about the horizontal axis without distortion of the face guard.

Abstract: This invention pertains to a fluid filter apparatus and more particularly to an improved fluid filter apparatus in which a plurality of disc-like filter elements or pads is preferably mounted on a perforated tubing, although, it can work without the tubing. Each filter element is a disc-like member having a hole cut in the center and is made of a filtering type material such as fiberglass, paper or felt. Each element is cut in a pattern such as a square, triangle or hexagon whose sides are straight or curvilinear which can be cut without waste. Adjacent stacked disc filter elements are orientated such that the configuration of two adjacent filter elements does not coincide. For example, in regard to a square type configuration filter element, adjacent elements are preferably rotated 45.degree. with respect to each other from their aligned position.

Abstract: An improved triangular filter cartridge and apparatus is provided comprising a generally cylindrical vessel having a plurality of generally triangularly shaped filter cartridges disposed therein.

Abstract: A top mounting pull-rope recoil starter as might be employed on a vertical crankshaft small internal combustion engine for rotary lawnmower or similar applications. The pull-rope pulley connects to a ratchet wheel through a twist-lock coupling and the spring chamber formed within the ratchet wheel and pulley is sealed against dust by a rotating seal formed between the pulley and starter housing. The ratchet wheel is selectively engaged by engine flywheel supported pawls, which have integral leaf springs normally biasing them into engagement with the ratchet wheel. When the engine is running, however, the centrifugal force generated by the rotating flywheel on the pawls moves the pawls against the bias of the integral leaf springs out of engagement with the ratchet wheel. The blower housing and starter housing are coupled together by a twist lock arrangement, and securely fastened together by a fastener, such as a threaded screw or a rivet passing through the starter housing into the blower housing.

Abstract: A keyboard system for an electronic musical instrument of the keyboard type, such as an electronic organ, synthesizer or electronic piano. The keyboard is responsive to the velocity with which the key is depressed and controls the tone generation circuitry to produce tones of higher amplitudes for higher key depression velocities. The keyboard also includes an aftertouch control whereby further depression of the key past its normal limit against a compressible medium, such as a foam rubber or felt washer, alters the quality of the tone produced. For example, the aftertouch control could be used to vary vibrato, change pitch, change decay, and the like. A pickup for each key is positioned in an electric field set up between two electrodes, and the voltage impressed on the pickup will change depending on the position of the pickup within the field as determined by the amount of depression of the key.
