Abstract: ABSTRACT OF THE DISCLODURE           A microscope is shown of generally clamshell-like con-figuration having top and bottom parts resiliently joined through a connecting structure.  Hand deflection of the parts, resilient-ly resisted, results in relatively reduced motion between lens and specimen for focusing.  The microscope may be formed as a unitary molding of resinous plastic or as a blank of foldable sections, and it may have built-in slide retainers. The light admitting aperture maybe used to precisely locate a liquid spec-imen for viewing within the focal-range of the microscope.

Abstract: ABSTRACT       A process is disclosed for the elimination of accumulated iron in the organic phase of a fluid-fluid extraction that contains di-2-ethyl-hexyl phosphoric acid.  This process involves treating said organic phase with an aqueous acidic solution of chloride ions, subsequently extracting the iron with an anionic ion exchanger leaving the di-2-ethyl-hexyl phosphoric acid iron-free for subsequent re-use, and regenerating the anionic exchanger by treatment with water to provide a relatively concentrated aqueous ferric  chloride solution.          Di-2-ethyl-hexyl phosphoric acid is used commercially as a cationic exchanger in the extraction of hexavalent uranium from sulfate  solutions, in the separation of uranium and vanadium, in the separation and purification of rare earths, in the separation of cobalt and nickel, and in many other such applications.

Abstract: ABSTRACT    Equipment for use in a high speed line printer or the like is disclosed which includes a series of independently actuable print hammers mounted for reciprocation in adjacent side-by-side paths.  All hammers are mounted on current car-rying spring  supports.  The shank of each hammer carries a coil which is positioned with the turns of each coil lying in planes which are normal to fields generated by rectangular permanent magnets, e.g. sintered ceramic magnets, which are disposed on opposite sides of the hammers, and which have zones of opposite polarity extending transversely of the series of hammers.  The coils on the hammers are located within portions of the fields generated by said zones of opposite polarity so that the hammers are individually driven along their paths upon delivery of an electrical impulse to the coils carried by the selected hammers.  Also disclosed is an arrangement of the coils on the hammers whereby coils are mounted in a staggered array with the coils on adjacent hammers disposed on opposite sides of the hammer shanks.  The coils adjacent one another on the same side of the hammers are arranged in stepwise fashions longitudinally of the hammers.  All hammer supports are shown as being mounted on common base members which also carry a printed circuit board which provides the control circuit for selectively impulsing the individual ham-mers in the series.

Abstract: TITLE:     TEXTURED FOOD PRODUCT.     ABSTRACT OF THE DISCLOSURE   Textured food products having a fibrous, lamellar or striated structure are produced by preparing a mixture of nutritious ingredients and water containing an anionic gelling agent, causing the gelling agent to set or form a gel in the mixture by reaction with a non-toxic metal ion and freezing the mixture with the formation of ice crystals either before, during or after the set of the gelling agent.   Divalent or polyvalent metal ions are preferred because these form thermally irreversible gels which maintain in the finished product the textured structure obtained by freezing even in the absence of heat coagulable materials    It is, however, preferred to include proteins in the composition for nutritional purposes and the resulting simulated meat products are stable to canning processes.  Preferred ionic gelling agents are pectates and alginates.

Abstract: CALIPER BRAKE ACTUATING CYLINDER     ABSTRACT OF THE DISCLOSURE     Pnuematic caliper brake actuator having diaphragm, piston member and cylinder body.  Cylinder body has outer por-tions having clearance recesses therein to accept the outer ends of arms carrying brake shoes.  At least two return com-pression springs extend between the piston member and outer portion of cylinder body, the springs having outer ends straddling the clearance recess and inner ends against piston member to retract piston when fluid pressure is reduced.  The clearance  recesses are hollow projections positioned off-centre and symmetrically relative to outer portion of cylinder and spaced apart to accept arm outer end therebetween and accept outer ends of the return springs therein to restrict lateral movement of springs.  Overall dimension across outer faces of projections on opposite sides of the cylinders is ap-proximately equal to an overall dimension across the outer por-tions of the opposed arms.  This results in extreme outer portions of moving portions of the caliper being generally within planes containing fixed portions of the caliper, re-sulting in an overall dimension across outer ends of the arms being less than would be possible with a single spring as used in prior art cylinders.
