Granted: 1988-10-25
Abstract: TITLE: SOD LAYING MACHINE AND METHOD A sod laying machine having front rear sections articulated together. A boom on the front section has arms extending forwardly, with gripper arms extending downwardly from the boom to grip a roll of sod. A control roller connected to the boom arms drives the sod roll to control its speed of unwinding. The sod roll has its grass side facing outwardly and its top unwinds rearwardly so an operator in a seat at the front of the machine, between the boom arms, has an unobstructed view of the critical area of sod extending in the air from the roll to the ground, to reduce the likelihood of buckles and tears therein. The machine passes over the sod after it is laid, to roll the sod.

Abstract: GRAFT POLYMERS OF POLYMERIZABLE MONOMERS AND OLEFIN POLYMERS                     ABSTRACT OF THE DISCLOSURE      Graft polymers are prepared by reacting an ethylenically unsaturated polymerizable monomer with a polymer of an olefin of 2 to about 8 carbon atoms in a process wherein the olefin polymer is substantially insoluble in the monomer but is cap-able of absorbing the monomer.  In a preferred aspect, a vinyl halide polyolefin graft polymer is produced by reacting a solid polyolefin particle with a vinyl halide monomer in which the polyolefin is substantially insoluble, but is capable of absorbing the monomer.  The solid particles can be contacted with the monomer in one step or in stages.  When the stage-wise reaction is continued until the proportion of polyolefin in the polymer product is about 2 to about 20 weight percent, the resulting product can be formed to a transparent or translucent article.  When a small proportion of solid polyolefin is em-ployed in the polymerization process, both a graft polymer and a polymer of the unsaturated monomer are simultaneously pro-duced in the same reactor and can be readily mechanically separated into the individual products.

Abstract: ABSTRACT OF THE DISCLOSURE      A fire responsive stem retention apparatus for a non-rising stem valve including an outer hollow sleeve secured to the top of the valve bonnet around the valve stem.  An inner cap is received in the outer hollow sleeve and closely fitted therewithin, and houses upper and lower stem bearings therein.  The inner cap has a shoulder which provides an upper support for the upper stem bearing.  Under normal environmental conditions, the inner cap is sweated to the outer sleeve with a thin layer of fusible mate-rial.   The  upper bearing  and  stem are prevented  from moving upward by the shoulder on the inner cap, and an annular shoulder on the stem is prevented from engaging a backseat in the bonnet.          Under fire conditions, the thin layer of fusible material melts rapidly, freeing the inner cap from the outer sleeve and permit-ting the stem to rise until the annular shoulder on the stem engages the backseat in the bonnet.  A screw in the inner cap rides in a slot in the outer sleeve, preventing removal of the inner cap from the sleeve.

Abstract: ABSTRACT OF THE DISCLOSURE         Polyol (allyl carbonate), e.g., diethylene glycol bis(allyl carbonate), are polymerized in solution, i.e., in an organic solvent, until about 20 to 50 percent of the allylic carbon-carbon linkages are consumed.  The solvent is then removed yielding a product that is gel-free, syrupy viscous liquid of unpolymerized monomer and polymer.          This liquid polymer can be polymerized to a hard, transparent material with less shrinkage.  Also described is the addition of mono-  or polyfunctional acrylates to the liquid polymer to produce a polymerizable mixture that can be cured quickly with the addition of a free-radical initiator.

Abstract: ASEPTIC FOOD PROCESSING APPARATUS AND METHOD            Abstract of the Disclosure A greatly improved aseptic processing apparatus and method for pumpable foods is pro-vided which gives accurate, uniform aseptic cook-ing conditions (e.g., time, temperature and pres-sure) while at the same time preserving the inte-grity of particulate in the food product.  In preferred forms, the apparatus includes a recipro-cating piston food pump which generates a continu-ous product stream at a substantially constant nominal pressure.   This stream is fed to a heat exchanger in order to elevate the temperature of the product, whereupon the stream passes through a holding  tube  to  complete  the  aseptic  cooking process.  A metering device such as a rotary pump is located downstream of the holding tube for creating a substantially constant flow rate of product from the apparatus.  Use of a downstream metering device in conjunction with an upstream constant pressure pump permits attainment of even, relatively high system pressures which in turn facilitates  accurate  temperature  control  and eliminates localized internal steam flashing which can deleteriously affect product quality.   By virtue of the present apparatus and method, asep-tic processing of low acid heterogeneous food products such as stews and chilies can be safely accomplished on a commercial scale.

Abstract: 13054b ROTARY MACHINING TOOL AND METHOD OF ITS MANUFACTURE                         ABSTRACT OF THE DISCLOSURE   The present invention is a rotary machining tool and a method of making it using an easily replaceable cutter element assembly. A circular saw is exemplary of a cutting tool which can be made using the present invention. The cutter element assembly comprises two portions. The first is an inverted, generally U-shaped clevis with spaced apart side portions that fit over the circumferential edge of a sawplate. The clevis has an upper portion which extends outwardly from the sawplate edge thereby defining a tooth retaining socket between the sawplate edge and the clevis. The side portions of the clevis are apertured to accept a pin for attachment to the sawplate which has a corresponding aperture. A buttress attached to the clevis normally bears against the leading edge of a gullet and prevents rearward rotation when in use. The second member is an insertable tooth having a head and an elongated tapered shank. The shank has a taper on its upper surface sufficient to form a self-releasing taper, ususally between 3° and 10°. The sides of the shank have less taper so as to form a self-locking taper, typically between 0° and 2.5°. The tooth shank is driven into the socket formed between the clevis and the sawplate. As the tooth is driven in, the clevis is forced radially outward against the attaching pin so as to tightly lock the assembly until the tooth is again driven out for sharpening or replacement. While the teeth may be sharpened in place on the sawplate, it is frequently advantageous to disassemble the saw and sharpen the teeth seperately. This permits a number of grinding configurations to be used which are not otherwise possible when the saw is fully assembled. The only tools required for saw assembly and disassembly are a hammer and punch. A 1.5 m diameter saw having 60 teeth can be completely retoothed in place in as little as 6 minutes.
