Abstract: ABSTRACT A photoprinting  apparatus includes a housing having a control panel for operation of the printer and a safe-light window through which a photo-sensitive strip of material within the housing can be observed during the orienting, exposing and developing of the image.  A reading font is disposed at the front of the housing and an imaging font corresponding in information and symbol location to the reading font is placed upon a table capable of rectangular coordinate movement within the housing.  An arm secured at one end to the font table overlies a detent plate having accurately spaced recesses therein.  Each recess corresponds to the center of a symbol on the imaging font and the reading font.  A pointer on the arm which extends over the reading font enables the operator to move the table to bring the imaging font in position to project a symbol upon a photosensitive sheet located within the housing.  An optical system within the housing is provided with a first safelight illumination source for projecting an image of the selected symbol upon the photo-sensitive sheet for spacing and aligning pur-poses.  A second light source exposes the image upon the sheet after electro-optical means have automatically corrected any baseline errors.  The font table and optical system can be shifted within the housing along spaced rods to change the magnification or point size of the symbols  on the font. Precise symbol size can be achieved by light sensors within the housing.  The quality of the developed images is maintained by solenoid actuated chemical dispensers which add fresh chemicals to the surface of the photo-sensitive sheet after each exposure.  Each symbol on the imaging font is provided with a base line reference bar which is projected with the image upon the photo-sensitive sheet.  The baseline reference bar is sensed before each exposure and the vertical position of the imaging font adjusted to its desired precise location before each exposure.  The photo-sensitive sheet is carried in the form of an elongated strip within a cassette in the housing from which it is fed into the exposing area in the housing.

Abstract: ABSTRACT OF THE DISCLOSURE     Spacer strips are positioned between vertically adjacent layers of timber in timber packages by locating a plurality of spacer strips which are supported by distribution members over the topmost layer of a timber package whereupon a plurality of depressors which are operatively associated with a frame structure are moved downwardly from an upper position so that respective depressors engage respective spacer strips supported by the distribution members so as to conduct and guide the strips downwardly into position upon the topmost layer of the timber package while the distribution members which support the strips are at the same time withdrawn from their supporting positions.          According to the invention, the despressors are arranged in a manner such that as the depressors move downwardly subsequent to engaging respective spacer strips, the frame structure with which the depressors are associated remains substantially stationary and, additionally, the downward motion of the de-pressors comprises a free fall preferably accomplished by pro viding a sliding fit of the depressors in the frame structure.

Abstract: ABSTRACT      A method of purifying aqueous solutions of iso-.alpha.-acids by removing .beta.-acids therefrom comprises first bringing the solution to an iso-.alpha.-acid concentration of 0.5% to 10% w/w, particularly 0.5% to 5% w/w, then reducing the pH to a value in the range 7 to 10, pre-ferably 8 to 9, so as to form an easily filtered preci-pitate of .beta.-acids.  Preferably pH reduction is effected by bubbling carbon dioxide through the solution.  The separated iso-.alpha.-acid solution may be concentrated to an extent that a phase separation takes place into two aqueous phases one of which has a higher iso-.alpha.-acid concentration than the other.  The recovered iso-.alpha.-acid solution is suitable for direct addition to beer without haze formation.

Abstract: ABSTRACT OF THE DISCLOSURE         Novel plating baths and the processes for plating therewith are disclosed which provide corrosion-resistant nickel/ zinc alloy coatings containing 13-15 weight/% of nickel for iron or steel substrates.  The novel baths have combined nickel and zinc contents in the range of 14 to 24 ounces of metal per gallon with the ratio of nickel to zinc maintained in the range 0.1:0.4.          These baths permit satisfactory plating of the alloy to be achieved at current densities in the range 30 to 120 amperes per square foot.  At alloy coating thicknesses in the range 0.00005 to 0.0005 inches, a salt spray corrosion resistance in excess of 0,5 hours per microinch is afforded.  Additionally, by coating the substrate, before alloy plating, with a substantially pure nickel priming layer, the corrosion resistance rate can be effec-tively doubled.  Apparatus for the continuous plating of the priming layer and the corrosion-resistant alloy layer is also described.

Abstract: Abstract of the Disclosure A tool such as a sledge or an axe is fastened on a handle by an adhesive which expands as it solidifies. A flexible sleeve is fitted on the handle and has a flange which is disposed at the lower end of the end portion of the handle that projects into the usual bore in the head.          The flange closes the bottom of the bore and the sleeve includes an upwardly projecting extension which engages the lower end of the wall of the bore so that the flange and the extension locate the head properly on the handle in both the horizontal and vertical planes. The end portion of the handle which projects into the bore of the head is smaller in cross section than the bore to leave a space between this end portion and the wall of the bore and this space is filled with an adhesive which is liquid when it is poured into the base but which expands as it solidifies to provide a firm connection between the handle and the head. The flange on the sleeve serves the additional purpose of sealing the lower end of the bore in the head and thus holds the adhesive in the bore until the adhesive solidifies.

Abstract: ABSTRACT Formation is excavated from within a retort site in formation con-taining oil shale for forming a plurality of vertically spaced apart voids extending horizontally across different levels of the retort site, leaving a separate zone of unfragmented formation beneath each void.  Explosive is placed in each zone, and such explosive is detonated in a single round for forming an in situ retort containing a fragmented permeable mass of forma-tion particles containing oil shale.  Formation is explosively expanded upwardly and downwardly toward each void.  A horizontal void excavated at a production level has a smaller horizontal cross-sectional area than a void excavated at a lower level of the retort site immediately above the produc-tion level void.  Explosive in a first group of vertical blast holes is detonated for explosively expanding formation upwardly toward the lower void, and explosive in a second group of vertical blast holes is detonated in the same round for explosively expanding formation upwardly toward the lower void and downwardly toward the production level void for forming a general-ly T-shaped bottom of the fragmented mass.

Abstract: ABSTRACT           The invention relates to a free-standing wall or partition assembly wherein a plurality of panel members are removably connected to upright support poles by a plurality of panel-to-pole clips.  In the invention a frame member along the edge of the panel member has a channel in which unitary clips having a base portion receivable in the channel are slidable.  Each clip has arcuate side walls to grip a support pole and planar walls connecting the side walls to the base.          The planar walls are resiliently biased against the edges of the channel to keep the clip in position but by squeezing the side walls together the clip  may be slid along the channel to a new location.  Also disclosed is a new and improved structure for joining adjacent pole sections together and a new and improved male and female clip assembly for directly joining panel members together without an intervening pole.
