Abstract: ABSTRACT OF THE DISCLOSURE   A laser recording device comprising a laser beam monitor (LBM) which can be utilized to generate a pulse train the pulses of which can be correlated with instantaneous beam position. Alternatively, the pulse train may be used as a controlling "clock" for the output shift registers of a CCD array. The LBM is characterized by the provision of a retro-reflective light pulse generator which allows a pulse detector of the monitor to be positioned adjacent the focus of another component of the recording device, for example, a ploygon scanner whereby the LBM is compact.

Abstract: ABSTRACT       In an assembly, for use in transducer type instruments such as accelerometers, having a position sensing movable member including a pick-off element, wherein the movable member is secured to a support member by a flexure or hinge and the support member in turn is cantilevered between two stator members, instrument bias errors resulting from the securing of the non-cantilevered portion of the support member between the stator members can be reduced by aligning the edges of the surfaces of the stators that contact the support member with the centroid of the pick-off element so that the axis of cantilever rotation passes through the centroid of the pick-off area.

Abstract: Docket 2481 Abstract Of The Disclosure A wide endless flexible band (10) is molded on a flat core blade (12) with one group of laterally extending rows of outwardly projecting printing characters (16) molded on one side of the core blade between a set of laterally extending notched guide bars (32). The notches within the guide bars are used to align the wide endless band on a rotary cylindrical arbor (40) precisely with a set of spaced cutters (44) which slit the wide band at laterally spaced intervals into a plurality of relatively narrow endless printing bands. The wide endless band is also molded with a second group of raised characters (14) which correspond to the printing characters and are positioned on the other side of the core blade between a set of laterally extending continuous guide bars (24). The continuous guide bars have outer surfaces which are flush with the outer surfaces of the raised characters and provide for precisely guiding a member (28) which removes a coating of color contrasting material from the outer surfaces of the characters to make them visually readable.

Abstract: ABSTRACT An open-cell electrolyte chlorine generator such as a type used for the chlorination of various aqueous streams including swimming pools is constructed without the use of a diaphragm or membrane isolating or partitioning the electrolyte between the anode and cathode. Instead, a gas separating plate separates the electrolyte above horizontally projecting electrodes, in order to keep the different gasses generated at the different electrodes separated as they rise to the top of the cell. Aqueous buffering reagents are added to the chloride-containing electrolyte to neutralize the hydroxide anions generated at the cathode and to optimize the evolution of chlorine gas by stabilizing the pH of the electrolyte. The chlorine and hydrogen gasses produced may be separ-ately added to the solution which is to be treated, with an optional cooling circuit taking the pre-treated solu-tion and passing it through the cell (in heat-exchanging tubing) prior to treatment with the gasses.  Thus during much of the operation of the cell, only the desired product (chlorine gas) and the easily disposed of hydro-gen gas must be removed from the cell.

Title: Strip pickling apparatus with straight-through strip  travel
Inventor: NOE OSKAR F
IPC: C23G3/02
Filed: 1982-10-27
Granted: 1985-04-23
Abstract: Abstract of the Disclosure A metal-strip pickling apparatus has feed means including upstream and downstream bridle-roller pairs for longitudinally displacing the strip under longitudinal tension along a straight transport path from the upstream bridle-roller pair to the downstream bridle-roller pair.  A housing longitudinally traversed by the strip is subdivided longitudinally by a succession of transverse partitions into a longitudinal succession of compartments each having a respective treatment bath, normally of acid.  Each partition has a rigid lower partition half having an upper edge and an upper partition half having a lower edge portion elastically engaging the upper Pace of the strip moving along the path.  The upper edges all are longitudinally aligned and touch the lower face of the strip moving along the path.  The acid baths have liquid levels above the upper edges of the respective lower partition halves.  The lower portions of the upper partition halves seal tightly with the strip and respective lower partition halves.  Thus liquid from one bath cannot pass between the respective partition halves into the next compartment.  The use of a straight transport path through the apparatus means that strip tension is irrelevant.

Abstract: Abstract of the Disclosure Apparatus for simultaneously controlling the contrast of broadcast color video signal information and auxiliary color graphics information displayed by the kinescope of a color television receiver.  Plural kinescope color signal coupling paths receive color video signals, a white drive graphics signal which is applied in common to the plural signal paths with a sense for enabling the kinescope to display color graphics information during graphics intervals, and plural blanking signals which are separately applied to the color signal paths for selectively blanking the outputs of the signal paths to determine the color of displayed graphics information.  A picture control signal simultaneously varies the level of the color video signal and the level of the common white drive graphics signal in the same sense.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for sending pressure pulses through drilling fluid in a drill string in a well bore includes an assembly adapted to be lowered from the surface through the drill string to a position adjacent the lower end of the drill string.  The external dimension of the assembly is substan-tially less than that of the internal diameter of the drill string, so there is always a substantial clearance between the assembly exterior and the drill string interior to per-mit a substantial flow of drilling fluid down the drill string, past the assembly, through a drill bit, and into an annular space between the drill string exterior and the well bore.  The assembly includes an internal bore to per-mit drilling fluid to flow through the assembly.  Means are provided for intermittently restricting flow of drilling fluid through the assembly bore to send the pressure pulses to the surface in response to the magnitude of a downhole condition to be measured.  The assembly includes means to permit it to be retrieved by a wire line from the surface and without removing the drill string from the well bore.

Abstract: Abstract of the Disclosure An improved bearing assembly supports a pair of parts for movement relative to each other.  The bearing assembly includes a plurality of rotatable bearing elements such as rollers, which engage raceways on the parts.  The bearing elements are disposed in openings formed in a longitudinally extending cage member which separates the bearing elements.  The cage member is supported by wear pads which engage at least one of the raceways.  The bearing elements roll along a central portion of the raceway.  Wear pads support the cage member.  To minimize scraping or marking of the portion of the raceway engaged by the bearing elements, the wear pads engage opposite sides of the raceway.  The wear pads extend through openings formed in the cage and can be readily disconnected from the cage to facilitate replacement.
