Abstract: CONVEYOR BELT CLEANER     ABSTRACT OF THE DISCLOSURE     A conveyor belt cleaner mounted on a transverse support member including an arm extending from a mounting bracket and a belt cleaner blade se-cured on the arm.  A positioning arrangement is pro-vided between the arm and the cleaner blade to allow the blade to rotate about the central axis of the arm within predetermined limits in either direction so as to allow the scraping edge of the cleaner blade to align with the surface of the conveyor belt being cleaned.  A nut and a resilient washer are provided to secure the blade against a collar.  An alternative securement includes a pin-and-slot connection which allows the same rotative action of the blade relative to the arm and having multiple seals against the en-trance of dirt into the connection.

Abstract: Abstact A method of treating shoe parts having a coating of a moisture-curable composition utilizes an apparatus in which a support (16) for an article, e.g. a lasted shoe S, can be supported within a chamber (30) in which the support can be enclosed.  The chamber (30) is supplied with heat and moisture.  More especially, the article is subjected to infra-red radiation from a heater (44) and steam is supplied to the chamber (30) such that the humidity of the atmosphere within the chamber (30) is maintained during the operating cycle at a dew point of between 50 and 60°C.  The surface temperature of the heater (44) is between 250 and 420°C, preferably between 300 and 380°C, and the article is subjected to infra-red radiation for a period of between 5 and 25 seconds, preferably 10 seconds.  Because the chamber (30) is enclosed, steam is supplied for only the first 5 seconds of the heating period.    To facilitate work handling, the support (16) is movable between a loading/unloading position and an operative position within the chamber (30), and an arrangement of screens (52, 54) is provided for closing the chamber respectively in the loading/unloading position and the operative position.  The screens also serve to cause the steam created during a cycle of operation to be evacuated into ambient atmosphere at the end of each operating cycle.

Granted: 1985-03-12
Abstract: Abstract An aerosol sprayhead assembly which includes a restriction between a sprayhead inlet communicating with an aerosol container and a nozzle opening which produces a fan-shaped spray pattern.  The restriction acts in coopera-tion with the nozzle opening to provide a more uniform spray than may be achieved using an otherwise identical sprayhead which does not include the restriction.  In one embodiment of the invention, the restriction defines an orifice formed as part of the sprayhead.  In another embodiment  the restriction defines a single orifice or a plurality of orifices located within an outlet tube terminating in the nozzle opening.  In a further embodiment of the invention, the restriction defines an integral reduced cross-section portion of the outlet tube.

Abstract: HEAD POSITIONING APPARATUS                 ABSTRACT OF THE DISCLOSURE           A head positioning apparatus for an HVTR has two rotary heads mounted to a rotating drum by electrically deflectable bi-morph leaves.  To trace tracks on the tape when the tape is played back at a speed different from that used to record it, tracking correction signals are repeatedly applied to the bi-morph leaves to deflect the heads into position to trace the tracks properly.  Residual deflection in the bi-morph leaves, when the tracking correction signals terminate at the end of each trace, is removed by a hysteresis-erasing signal that flexes the bi-morph leaf back and forth.  The polarity of the hysteresis-erasing signal depends on whether the tape on playback is running faster or slower than the recording speed.

Abstract: ABSTRACT OF THE DISCLOSURE     Control circuits are provided for a heat exchange unit including environment responsive means placed in the general area of the heat exchange unit's heat exchanger or of the associated heat distribution network or return system.  The environment responsive means is connected in series between the heat exchange unit's main control switch, such as a thermostat, and the fuel valve which controls the flow of fuel to the unit's burner.  The environment responsive means may be either independent of, or connected in parallel with a heat circulator if any, associated with the unit's heat exchanger.  The control circuits of the present invention control the action of the heat exchange units fuel valve to create an intermittent heating flame in response to environmental changes at the heat exchanger, heat distribution network or return system during each heat demand cycle.  This conserves fuel and energy by intermittently terminating the flow of fuel, and thus the burning of fuel, during each heat demand cycle while continuing to utilize and distribute heat stored in the heat exchanger during non-fuel burning periods of each heat demand cycle.

Abstract: ABSTRACT An improved engine construction is disclosed having a valve train including valves and corresponding valve stems for controlling the intake and exhaust ports, cams for imparting reciprocating motion to the valves by way of the valve train, and a valve spring for biasing each valve toward its closed position and the valve train into tracking relation with the cam.  The only element of the valve train coupling a cam to a stem is a cam follower with a depression for receiving the corresponding stem end and a cam engaging surface opposite the depression with the cam follower being held captive intermediate the stem and cam solely by the spring biasing of the stem toward the cam and the engagement of the stem end and the depression.  The spring biasing is provided by a coiled wire spring having outwardly extending legs each of which engages a corresponding stem to urge the valves toward their closed position.  The bight or coiled portion of the spring is held in a relatively fixed position by a portion of the engine casting.  Another feature of the engine resides in the engine block casting which includes an exhaust gas passageway extending from an engine cylinder and including near the end thereof remote from the cylinder an enlarged cavity which defines at least a part of a muffler shell.  Numerous other elements may be cast integral with the engine block including a boss for attaching a pull rope recoil starter assembly along with an anchoring point for one end of the rewind spring of that starter assembly and retaining guides for the rope of the starter assembly.  The locator, such as a stud for the intake and exhaust poppet valve biasing spring, may also be cast integrally with the engine block.  A further feature of the engine resides in a combination crankcase breather mechanism and oil fill cap which due to its remote location from the engine crankshaft as well as the tortuous air flow path through the cap to the atmosphere minimizes the egress of oil from the engine through the breather mechanism.
