Abstract: ABSTRACT OF THE DISCLOSURE            In copying apparatus having a magnification ratio varying device, wherein a photosensitive member in motion is exposed to an optical image of an original by slit exposing to form an electrostatic latent image thereon and the original scanning velocity is varied in accordance with the magnification ratio selected, it  is necessary to effect registration of the forward end of the image of an original with the leading end of a photosensitive sheet or a transfer-printing sheet.         The above-mentioned registration is effected by delivering a copy sheet after lapse of a predetermined period of time following the production of a detection signal by a detection means, the above-mentioned predetermined period of time being varied in conformity with the selected one of magnification ratios.

Abstract: NEUTRON ABSORBING ARTICLE AND METHOD FOR       MANUFACTURE OF SUCH ARTICLE            ABSTRACT OF THE DISCLOSURE:         A neutron absorbing article, preferably in long, thin, flat form, suitable for but not necessarily limited to use in storage racks for spent nuclear fuel at locations between volumes of such stored fuel to absorb neutrons from said spent fuel and prevent uncontrolled nuclear reaction of the spent fuel material, is composed of finely divided boron carbide particles and a solid, irreversibly cured phenolic polymer forming a continuous matrix about the boron carbide particles, in such proportions that at least 6% of B10 from the boron carbide content is present therein.  The described structures possess a multiplicity of desirable properties for the` use mentioned, including withstanding thermal cycling from repeated spent fuel insertions and removals, withstanding radiation from said spent nuclear fuel over long periods of time without losing desirable neutron absorbing and physical properties, being sufficiently chemically inert  to water so as to retain neutron absorbing properties if brought into contact with it, not being galvanically corroding and being sufficiently flexible so as to withstand operational basis earthquake and safe shutdown earthquake seismic events without loss of neutron absorbing capability and other desirable properties when installed in storage racks for spent nuclear fuel.  In preferred embodiments of the invention the phenolic polymer is a phenol formaldehyde type polymer, such as a trimethylol phenol formaldehyde type polymer, the boron carbide contains at least 12% of B10, the plate contains from 8.0 to 11.5% thereof, the plate density is 1.6 to 2.1 g./cc. and the proportions of boron carbide (which may be accompanied by limited amounts of certain impurities) and phenol formaldehyde type polymer (preferably free of halogens, mercury, lead and sulfur) are from 20 to 35% of the former and 65 to 80% of the latter.  The invention also relates to a plurality of such neutron absorbing articles in a storage rack for spent nuclear fuel and to a method for the manufacture of the articles.  In the manufacturing method a portion of the phenol formaldehyde type resin, in liquid state, is mixed with the boron carbide particles, compacted and cured, after which the cured article is impregnated with additional phenol formaldehyde type resin, which is then cured to make the final product.

Abstract: ABSTRACT OF THE DISCLOSURE         In a measuring device such as a coilable tape rule, the movable elongated measuring element or blade is provided with a series of optical markings to indicate passage of distance.  Photoelectric sensing means in the form of a pair of sensors carried by the stationary ele-ment such as the tape rule housing detects shifts in light level or transitions provided by the markings when the blade is illuminated and moved to traverse a distance being measured.  A phase relationship of the sensors and the  markings is utilized by logic circuitry to provide signals indicative of both amount and direction of move-ment.  The logic signals are counted to indicate net distance traversed by the blade which indication is con-verted to units of measure and visually displayed.  The blade can include conventional graduations and related indicia along with the optical markings so as to be both human readable and machine readable.  Duplicate pairs of sensors are provided and signals associated with both pairs are compared for error detection, and the error detection circuitry has an externally applied reset controlled according to signals associated with the sensor pairs.

Abstract: ABSTRACT      The present invention relates to a method of extracting gold from placer gravel.  Whereas conventional techniques are relatively effective in the processing of coarse gold particles, i.e. plus ten mesh tyler, the present invention finds application in recovery of gold particles of all sizes from submicroscopic through coarse nuggets larger than ten mesh tyler.  A rotating sluice box uses centrifugal force to enhance the sluicing process, and a centrifugal amalgamator then extracts gold from the concentrate thus produced, under centrifugal force.  Gold is removed from the mercury by conventional techniques.

Abstract: ABSTRACT          The present invention is directed to electrical connectors and more particularly to interstage connectors for guided missile stages.  Specifically, the present invention relates to a  connector wherein the contact members supported within the connector component housings may be engaged and disengaged independently of the engagement and disengagement of the housings.  Most prior interstage connectors utilize pin and socket type electrical contact members which are aligned parallel with the connector's central axis.  Thus, the connector contact members are subject to damage or shorting if the contacts are not engaged and disengaged along a line substantially parallel with the central axis of the connector component housings.  In the connectors of the present invention, actuator means are provided for engaging and disengaging the connector contact members independent of the engagement and dis-engagement of the connector housings and include a movable insert member disposed within a second housing for movement between mating and non-mating positions.  The contact members supported within the second housing each include a terminal portion, an active contact portion carried by the insert member for engagement with a first housing contact member, and an extendable portion for maintaining electrical connection between the active and terminal portions as the insert member is moved between its mating and non-mating positons.  The actuator means further include a latching mechanism for moving the insert member to its mating position to securely interengage the connector contact elements, and a separation assembly for disengaging the connector contact members prior to disengagement of the connector housings.

Abstract: APPARATUS FOR THE DISPLAY AND DISPENSING            OF MERCHANDISE              Abstract of the Disclosure Apparatus for the display and dispensing of merchandise with at least one vertically extending carrier supporting the goods.  The carrier can be slid out of the apparatus into a position in which it extends most of the way out of the apparatus, this position being determined by a stop, the goods being readily observable in this posi-tion.  The stop limiting the sliding-out distance of the carrier can be selectively manually displaced from its operative position, whereupon the carrier can be pulled out in its entirety and detached from the apparatus.  The goods can be removed from the carrier only after the latter has been detached from the apparatus.  Upon re-insertion of the carrier, the stop automatically snaps behind the carrier, so that no special manipulation of the stop is needed at this time.

Abstract: SLEEVE VALVE HYDRAULIC JAR TOOL Abstract of the Disclosure A hydraulic jarring tool includes a reliable and closely repeating hydraulic detent actuation means.  The jarring tool includes an outer member and an inner member telescopically arranged.  Spline means between said outer member and said inner member transmit torque.  A hammer and anvil system provide a jarring effect upon actuation of the tool.  An upper seal and lower seal provide a fluid seal between said outer member and said inner member.  A working fluid is maintained in a working fluid chamber between the upper and lower seals.  The detent actuation means provides a tripping action to produce the jarring effect.  Annular grooves in a lower stop member cooperate with a sliding sleeve element to provide orifice passages that produce the detent action by the slow metering of the hydraulic working fluid.  Large bypass holes through the sleeve element allow the working fluid to flow rapidly in the opposite direction to recock the jar tool.
