Abstract: Abstract A lattice type girder has upper and lower chords between which extend inclined struts.  The struts may be of continuous zig-zag form with interconnected sections.  The ends of the struts or strut sections are received in recesses in the chords and secured therein by a hardening and binding substance, such as urethane plastics or epoxy glue.  This substance fills the recesses and preferably has the same compressive and tensile strength as the material of the chords.

Abstract: ABSTRACT      An alignment and exposure system is provided with a main stage for positioning a reference mark or a semicon-ductive wafer directly beneath a projection lens.  The reference mark is mounted on the main stage by a substage permitting the reference mark to be positioned in alignment with the axes of motion of the main stage and in a plane parallel to and coincident with the image plane of the projection lens.  Selected portions of a reticle disposed above the projection lens on another stage may be illuminated with either exposure or nonexposure light by a controllable light source unit.  While employing the projection lens and a first objective lens unit to view images of portions of the reference mark or wafer illuminated by projected images of the illuminated portions of the reticle, the main or other stage may be employed to directly align the wafer with respect to the reticle or the reticle with respect to the reference mark.  While employing a second objective lens unit to view images of portions of the wafer illuminated by projected images of a pair of prealignment reticles, the main stage may be employed to align the wafer with respect to those reticles.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to the self-contained tech-nical means and may be advantageously used for carrying out geological, hydrographic and oceanological works.      An apparatus for taking bedrock samples from the bottom of deep-water basins comprises a float with a rod and support-ing frame, containers with ballast weights and a working member. A casing of the working member is made split with an open bottom. Disposed inside the working member casing is a shell destroyed when acted upon by an initiating device at the moment the work-ing member gets in contact with the bottom of a water basin, and a device for catching and holding a sample. The initiating device is installed in the upper part of the working member and provided with a release mechanism operatively associated with a device for dropping ballast weights.      The upper part of the working member casing is provided with a thrower. The lower part of the working member casing is provided with a packing ring.      The device for dropping ballast weights is located in the middle part of the supporting frame coinciding with the float rod provided with pin-type catches cooperating with flex-ible links fixing the ballast weights.

Abstract: IMPROVED CONTENT-ADDRESSED TEXT SEARCH             APPARATUS FOR TYPEWRITERS                Abstract of the Disclosure search system is provided that locates a reference point in a string of text-representative codes based on comparisons with an operator keyboarded text string (the address string).  Such comparisons are automatically modified, however, to equate certain codes and code patterns that present an ambiguity to the operator in establishing the address string, e.g. a tab operation and a series of space operations may have the same apparent result for printing but are stored as different codes.  By so expanding the acceptable "matching" code patterns selectively with respect to the codes presented for comparison, the likelihood of operator success in identifying a desired text location is increased significantly.

Abstract: ABSTRACT   The invention concerns a new way of purifying crude 6-[D-2-(D-2-amino-3-N-methylcarbamoyl-propionamido)-2-p-hydroxyphenylacetamido]penicillanic acid.  This is achieved by the steps of:  (A) contacting an aqueous solution of 6-[D-2-(D-2-amino-3-methylcarbamoyl-propionamido)-2-p- hydroxyphenylacetamido]penicillanic acid with a nonpolar, macroporous styrenedivinylbenzyle copolymer absorption resin to adsorb 6-[D-2-(D-2-amino-3-N-methylcarbamoyl- propionamido)-2-p-hydroxyphenyl-acetamido]penicillanic acid on the resin, (B) eluting the adsorbed 6-[D-2-(D-2-amino-3-N-methylcarbamoyl-propionamido)-2-p-hydroxyphenylacetamido]penicillaanic acid or a mixture of water and a water-miscible organic solvent, and then (C) isolating pure 6-[D-2-(D-2-amino-3-N-methylcarbamoyl-propionamido)-2-p-hydroxyphenyl-acetamido]penicillanic acid from the eluates.  This process enables the recovery of the purified compound in high yield by a simple absorption-elution operation.

Abstract: JACKETED WOOD STOVE     ABSTRACT OF THE DISCLOSURE  A jacketed wood stove has a jacket forming an air space conformably surrounding the top, bottom, rear and sidewalls of the firebox, and a double-jacketed front access door.  The periphery of the access door is slotted for internal convective cooling of the door.  Ambient air enters the air space beneath the firebox, flows rearwardly, then upwardly behind the firebox and forwardly along the top and sidewalls of the firebox to progessively heat the air and to cool the outer jacket.  A reflective intermediate baffle between the jacket and the side and rear walls of the firebox further cools the jacket.  Heated air returns to the room via sidewardly-directed outlet slots along the upper and frontal margins of the jacket sidewalls.  A pedestal supports the jacketed firebox above the floor.  The pedestal contains a first conduit for introducing ambient air into the air space and second conduit for introducing outside combustion air into the firebox. The pedestal also houses a blower for blowing air into the air space.  A horizontal baffle inside the firebox deflects the flames and hot gases forwardly and laterally against the firebox walls to more efficiently extract heat from the fire.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a method of joining together lengths of fiber reinforced plastics pipe and pipe fittings wherein the pipe lengths and fittings are each provided with an annular end portion adapted to be bonded to an adjacent length of such pipe.  According to the invention such annular end portion is provided with a surface layer of a textile fabric, such fabric being embedded in plastics material and being releasable therefrom upon application of sufficient force.  In preparation for joining said annular end portion to another length of the pipe or fitting, a force is applied to such surface layer which is sufficient to cause the same to be peeled off thereby to expose a clean surface on the annular end portion.  This clean surface, having a roughness dependent upon the texture of the fabric, serves to facilitate the making of a strong bond between the surfaces which are to be joined.

Abstract: RCA 75,661 ABSTRACT         A circuit is disclosed for automatically blanking the kinescope of a color television receiver during channel changing intervals.  The receiver also includes an automatic kinescope beam current limiter, plural kinescope driver stages, and a source of reference bias voltage to which video signals amplified by the kinescope driver stages are normally referenced, coupled in common to the plural kinescope driver stages.          During channel changing intervals, the blanking circuit modifies the reference voltage with a given blanking response time so that the driver stages and kinescope are blanked.  The blanking circuit exhibits an unblanking response time, slower than the blanking response time, for permitting the reference bias voltage to gradually return to a normal level after the channel change interval ends, at which time the driver stages and kinescope are unblanked and operate normally.

Abstract: ABSTRACT OF THE DISCLOSURE   A thick film line modulator/scanner (50) for use in an electro-optic line printer (14). A light valve utilizes a thin electro-optic layer (212) with the index of refraction of the layer being higher than the neighboring material so that the light can be guided in it. A laser beam (48) is focused into the layer, the beam expanding sideways so that a sheet of collimated light is provided. This light is affected by an array of electrodes (240, 242), consisting of an extended set of individually addressed metal fingers (240) on one side of the film (212), and a broad electrode (242) on the other side of the film. This broad electrode could also be segmented to the individually addressed electrodes. The light diffracted by this electrode set is reimaged onto the recording medium (14) with the zero order diffracted light blocked out, so that each electrode acts as a light modulator for one picture element on the output.
