Abstract: ABSTRACT OF THE DISCLOSURE A column sensor includes a disc which is rotatably supported at one end of a lever arm  and in proximity to a card reading station of a manually operable card reader. The lever arm is itself supported for rotation and biased by a spring bearing on an end of the lever arm so that a circumferential surface of the disc is urged into contact with one of the major boundary surfaces of an elongated passageway in the card reader. As a card is moved through the passageway, incremental rotation of the disc due to contact of the circumferential surface thereof with a surface of the card is detected by a light source-light detector pair mounted on the lever arm and on opposing sides of the disc, with light being coupled from the light source to the light detector through a plurality of circumferentially-spaced, axially-extending apertures in the disc so that the light detector accordingly provides an alternating electrical output signal representative of the spacing of data columns on the card.

Abstract: ABSTRACT  In a Power Propelled Reciprocating Piston Pump Liquid Sprayer, it is known to have a reservoir which is mounted on a frame to whose cross members wheels are attached by which the said reservoir with its contents is propelled foreward.  The power unit mounted on the said reservoir can be either electric or the gas powered engine type, it drives both the sprayer and the reciprocating piston pump mounted at the base of the said reservoir. The said pump employs a spring tensioned rubber piston with manual adjusting mechanism and is reciprocated by a power driven crank.  On the induction stroke liquid in the said reservoir is drawn through the sliding disc valve into the cylinder, on compression, contents is forced through a spring ball loaded valve into a separate chamber situated within the said reservoir. From the said chamber runs a tube to the exterior of the said reservoir. where a flexible hose is attached with a spray nozzle on the end.  Spring loaded release valve with the pressure adjustment and a faucet are situated on the said chamber which enable any surplus fluid to be released back into the said reservoir.  The poser to the rear wheels is transmitted via a "V" belt to a pulley attached to the said crankshaft to which a sprocket is attached and from which power is further transmitted via a link chain, clutch and shaft arrangement, propelling the sprayer in the foreward direction and reducing its speed to approximately walking pace.

Abstract: OPEN TOP REFRIGERATED DISPLAY CASE     HAVING AMBIENT AIR DEFROST                 ABSTRACT OF THE DISCLOSURE        An open top refrigerated display case having an ambient air automatic defrost system and a method of operating such a case.  A single air conduit extends in a U-shaped formation along opposing side walls and the bottom wall of the display case.  The air conduit has openings at both ends in the location of the upper portions of the side walls.  Arranged within the air conduit is at least one reversible fan and a set of refrigeration coils.  During a refrigeration cycle the fan circulates air through the air conduit in a first direction towards the refrigeration coils.  When frost buildup within the display case has reached a certain level, the system is switched to a defrost cycle.  During the defrost cycle, the fan circulates the air in the opposite direction through the air conduit and draws in ambient air from outside of the display case.          Since such ambient air is of a lower temperature than the normally refrigerated air, it serves to defrost the system.  The ambient air, after passing over the evaporator coils and through the air conduit, is expelled from the air conduit in a direction towards the outer side of the refrigerated case and away from the interior of the case.

A windshield wiper transmission link is also connected to the crank arm.  The crank arm has an inner diametral bearing surface which is rotatably supported on a pin secured at one end in cantilever fashion to a housing, and an outer diametral bearing surface which is adapted for rotatable support in a cylin-drical opening in another housing.  The outer bearing surface has axially extending recesses in which a lubricant is retained.  When high transmission loads are applied to the crank arm, the pin deflects slightly so that the increased bearing loads are supported on the outer bearing surface to prevent further deflection of the pin.

Granted: 1983-10-18
Abstract: ABSTRACT         The invention is to provide an improved process for preparing polyolefins having predetermined properties, in particular, melt index and/or density by polymerizing olefin in the presence of a Ziegler catalyst and hydrogen. The parameters corresponding to the concentrations of olefin and hydrogen, participating in the properties, in the gas phase of reactor are detected by high-speed gaschromatography. The detected signals are applied to a computer.           The feed volumes of olefin and hydrogen into the reactor are controlled by means of an operation control output, and the respective concentrations in the reactor are controlled.  Consequently, the resulting polyolefins possess extremely stable and uniform properties.

Abstract: ABSTRACT      The invention relates to a process and an installation for the heat-treatment of fine-grained material.    Before it is introduced into the precalcination zone (4), the waste air  from the cooling zone (3) is divided into two component streams into which the partial quantities of material coming from the two preheating zones (2, 5) are introduced. Separately measurable quantities of fuel are added to these two component streams before they are combined with one another.    In this way, the material is maximally de-acidified in the precalcination zone (4) before it is introduced into the calcining zone (1) without any danger of deposits being formed in the precalcination zone.

Abstract: Abstract of the Disclosure This, invention is a volatile hydrocarbon detector apparatus to continuously sample methane gas in an oil well drilling mud.          The detector apparatus includes 1) a gas sampler assembly to gather the methane gas from the drilling mud; 2) a control module assembly to receive and amplify electrical signals from the gas sampler assembly; and 3) a recorder assembly to receive output electrical signals from the control module assembly.    The recorder assembly is of conventional nature and operates to record on a paper roll the date, time of day and the amount of methane gas present in the drilling mud.  The main novelty lies in the gas sampler assembly which includes 1) a hood assembly to straddle a flowing channel of drilling mud; 2) a sensing head assembly mounted in the hood housing assembly to measure amount of methane gas therein; and 3) a pump assembly operable to draw inlet air through the sensing head assembly and discharge air into the channel of drilling mud. The discharge air acts to agitate the drilling mud to increase release of methane gas therein to trans-mit a more accurate measurement of the methane gas to the recorder assembly.
