Abstract: CONTACT PLATE FOR HEAT-MASS EXCHANGE                     APPARATUS                 ABSTRACT OF THE DISCLOSURE      The present invention relates to contact plates for heat--mass exchange apparatus and may be used in various branches of industry and in production of polymeric materials.  The plate has a base provided with at least one perforation widen-ing in one direction, its edge with its widening end contact-ing the apparatus walls.  With a plate having a plurality of perforations the edges of the perforations disposed along the periphery of the base contact the apparatus walls and the edges of adjacent perforations contact each other, thus reduc-ing the development of stagnant zones on the plate, decreasing its hydraulic resistance and improving the efficiency of heat--mass exchange.

Abstract: ABSTRACT     An agricultural irrigation machine of the hose-drum type in which a hose through which water is passed leads from a drum on which the hose is wound to an irrigation trolley or sledge carrying a nozzle or water-gun.   The hose-drum is mounted to rotate about a horizontal axis on a turret which can be turned about a vertical axis, whereby the hose-drum can be oriented in the direction of the unwound part of the hose.   The hose-drum is driven in the hose-rewinding sense while water is flowing through the hose to the irrigation trolley or sledge.  In known hose-drum machines of this type, the hose-drum is mounted on a horizontal axle or shaft supported at its ends in brackets upstanding from the turret.  In the irrigation machine of this invention, there is no axle or shaft; instead the hose-drum rests in a cradle of rollers and is driven in the hose-rewinding sense by a sprocket wheel engaging a captive chain wrapped around a peripheral channel on a flange of the drum.

Abstract: ABSTRACT           An oil feed system for an oil burner is disclosed.  The feed system includes an oil preheater through which the oil is pumped to ensure that the oil fed  to the burner nozzle is warm enough to ignite easily and completely.  A purge line is provided to recirculate the standing oil in the supply line which leads to the burner nozzle back through the heater so that on start up cold oil is not sprayed from the nozzle.  A solenoid valve in the purge line opens for a predetermined time initially during which oil is recirculated.  It is not necessary to close off the burner nozzle during this period because the nozzle presents a considerably higher resistance to the oil than the purge line which is connected through the solenoid valve to the suction side of the feed pump with the result that the cold oil flows directly to the purge line.

Abstract: ABSTRACT     A torroidal oxy-fuel burner capable of operating on a low. pressure natural gas supply comprises a barrel having a conical opening and a cone which is disposed in the conical opening and defines one wall of a conical passageway extending between the cone and the conical opening.   In use, oxygen is passed through the passageway and natural gas is directed into a fuel supply port which is disposed radially outwardly of the outlet of the passage-way.    The oxygen leaving the conical passageway entrains the natural gas from the fuel supply port and forms a torroidal flame down-stream of the cone.    The burner can be fired on other gaseous or liquid fuels if desired.

Abstract: ABSTRACT OF THE DISCLOSURE:           A device for the dimensional measurement of articles comprises a receiver spaced from and aligned with a source for emitting a light beam.  The receiver receives the light beam and emits a corresponding signal. The source and receiver func-tion as a photo-coupler unit. First and second supports support individual articles to be controlled and the photo-coupler unit.          A motor provides relative movement between the first and second supports thereby causing blocking of the light beam by the ar-ticle and carrying out the scanning of the article. A digital counter has minimum and maximum preselectable measurement values.          A measuring device measures the signal produced by the receiver during scanning. Logic circuits couple a linear transducer to the counter to control the readout thereof. The measuring device includes a linear amplifier connected to the receiver which amplifies the signal produced by the receiver and is calibrated to a level such that it provides a signal only when the axis of the light beam is blocked by the article.The linear transducer directly measures the relative movement of the supports thereby directly and accurately measuring articles of any shape and length greater than one micron.

Abstract: ROTARY SHEAR     ABSTRACT OF THE DISCLOSURE             An improved rotary power shear that includes an electric motor which drives, through a reduction gear assembly, a rotary shear assembly comprised of a driving shear wheel which rotates against a cooperating driven shear wheel. The design of the tool is characterized by a handle that extends above the motor housing and gear casing, and which supports the tool at one end from the gear casing and at the other end from the rear of the motor housing.  In this manner the tool is balanced when held by the handle as the weight of the gear casing and cutting assembly at the forward end of the tool offsets the weight of the motor at the rearward end Or the tool.  In addition, the design of the tool is facilitated by the provision of a single bracket member that serves the multiple functions of supporting and biasing together the rotary shear wheels, providing a cover for the gear casing, and also providing a support for the stub shafts on which the gears are journalled.          An overload release clutch is also incorporated into the reduction gear assembly to protect the tool from being damaged by excessive workpiece resistance. The preferred embodiment of the tool further includes a forward-and-reverse switching capability.

Abstract: Abstract A focusing mechanism for a camera includes a drive arrangement for displacing the camera lens in accordance with the contents of a counter into which the output of a pulse generator is gated during a range pulse whose dur-ation is directly related to the distance of a subject from the camera.  The pulse generator is programmed so that its pulse repetition rate matches the time-derivative of the function relating the subject distance to the lens pos-ition at which a subject is in focus.  Integration of the generator output is carried out by gating the generator pulses into a counter during the range pulse such that at the trailing edge of the range pulse, the contents of the counter will be the integral of the time-derivative evaluated between the lim-its of the range pulse, i.e., a definite integral representative of the lens position at which a subject will be in focus when located at a distance de-fined by the duration of the range pulse.  For fully automated operation as applied to a still camera, shutter actuation can be in response to arrival of the lens to the position at which the subject is in focus.  Applied to movie cameras, the lens can track a moving subject maintaining it in focus during filming.
