Abstract: ABSTRACT OF THE DISCLOSURE       Described herein are compositions and processes for preparing molded articles wherein shrinkage is substan-tially avoided by providing a thermosetting composition which foams during cure, resulting in articles with very smooth surfaces and which are weatherable.  In one aspect, the invention comprises a thermosettable composition com-prising:  (A) from about 20% to about 70% by weight, based on said composition, of an unsaturated monomer; from about 1% to about 50% by weight, based on said composition, of (B) a thermoplastic polymer soluble in said unsaturated monomer; and from about 10% to about 40% by weight, based on said composition, of (C) a polyunsaturated crosslinking monomer, the amount of (C) being sufficient to cause the cured thermoset resin molded under heat and pressure from said composition to have an optically heterogeneous appear-ance due to foaming during cure, and a density significantly less than the theoretical density if unfoamed.  Also provided is a process for preparing fiber-reinforced foamed thermoset moldings comprising the steps of (? preparing a composition comprising from about 20% to about 70% by weight, based on said composition, of (A) an unsaturated monomer; from about 1% to about 50% by weight, based on said composition, of (B) a thermoplastic polymer soluble in said unsaturated monomer; from about 10% to about 40% by weight, based on said composi-tion, of (C) a polyunsaturated crosslinking monomer; and (D) a fibrous reinforcing agent selected from the class of materials consisting of fiberglass, sisal fibers, asbestos fibers, cotton fibers, nylon fibers, polyester fibers, poly-propylene fibers, quartz fibers, beryllium fibers, boron fibers and carbon fibers; and then (2) curing said composition at a temperature ranging from about 200°F to 350°F and under pressure in a mold; the amount of component (C) in said composition being sufficient to cause foaming, substantial reduction of density below theoretical density, substantial absence of shrinkage, and reduced fiber prominence.  Articles made from the aforesaid composition can be used without finishing or sanding steps and without the necessity of applying a protective coating.

Abstract: ABSTRACT OF THE DISCLOSURE        Continuous-tone original picture information, such as a photograph or original art work, is put into a form suitable for half-tone printing reproduction by raster-scan reading of the original to produce a varying video signal.  The video signal is rendered suitable for writing in a high speed writer by continuously convolving (weight-ing, multiplying) said signal with stored halftone dot data (attenuation) signals obtained from a Read Only Memory, and applying the resultant treated signals, through a quantizer, to control a beam of radiation to expose a sensitive printing or recording medium to a halftone image pattern in which each dot is configured to provide optimum image information transfer to the reproduction medium.  Simulations of the effects of conventional "bump" and "flash" exposures, and of other screen-modifying parameters, can be introduced as desired, and suitable apparatus combinations for performing all these operations are dis-closed.

Abstract: Abstract of the Disclosure A diagnostic arrangement is disclosed for use in conjunction with communication system to detect scanning difficulties. More specifically, duplicated scanners synchronously but independently provide reports indicating changes of state of a plurality of scan points.  These reports are first buffered at the scanners and then transmitted over data links to a remote processor where the reports are compared.  A mismatch indicates either a malfunctioning scanner or other scan point difficulty. To pick a scanner which is providing correct reports, simulation means in each scanner are controlled, when the associated scanner scans the problem scan point, to cause the problem scan point to appear to assume one state and to cause all the other scan points to appear to assume another state.  When each scanner generates a report for this problem scan point, each report is bypassed around a buffer for immediate transmission to the remote processor.  Because the processor expects to receive a predetermined report, the "malfunctioning" scanner can be detected based upon analysis of the reports actually received.

RIVELLI                ABSTRACT OF THE DISCLOSURE         A probe mounting apparatus adapted for use in the deep fat frying of French fries, fish, chicken and the like, wherein the length of cooking time is to be calculated by a timing computer responsive to the temperature of a pre-determined portion of the cooking medium as sensed by a probe assembly including a stiff  sleeve formed of a smooth surfaced metal and containing a temperature sensing element at its end.  The probe assembly is repeatably and accurately attached to the fryer and immersed with its sensory element in a precise location in the cooking medium by means of mounting apparatus comprising:  a mounting block fixedly attached in a predetermined location on the fryer and having an opening therein, such as a slot, arranged to receive the probe sleeve and to define the position of the probe's longitudinal axis in the cooking medium. The block contains gripping devices, such as releasable ball detents, to hold the probe sleeve in the block, and the longitudinal position of the probe sleeve in the block is fixed by positioners such as  collars on the probe to accurately define the position of the temperature sensing element immersed in the cooking medium.  The end of the sleeve is repeatably fixed in the predetermined portion of the cooking medium, thereby supply-ing uniform temperature data input to the computer despite repeated removal of the sleeve from the fryer for cleaning, and probe manufacturing and installation are simplified.
