Abstract: A broad band antenna suitable for mounting on a ground plane comprises a pair of spaced-apart, linear hollow monopoles perpendicular to the ground plane and an air-dielectric coaxial transmission line extending linearly between the monopoles parallel to the ground plane. Means are provided grounding the outer conductor of the transmission line to the ground plane, the inner conductor top-connecting the monopoles.

Abstract: In a large high temperature industrial dryer or other such heated enclosure, a structural heat-insulation panel including opposed metallic sheets in generally parallel, spaced-apart planes, one of said sheets being exposed to a higher temperature than the other sheet, and insulation means between such sheets, wherein the improvement comprises panel ends formed of stainless steel of low heat conductivity. Particularly low heat transfer to the lower temperature sheet is obtained by employing embossed stainless steel pieces as said panel ends.

Abstract: A reconstituted pimiento strip useful for stuffing olives using automatic equipment is prepared by employing a forming apparatus comprising a pair of opposed, continuous belts, the lower belt being recessed on its mating surface to define a trough into which a mixture of pimiento and binder is introduced. The orientation of the belts relative the horizontal is such that both belts dip into a calcium chloride setting bath at a point intermediate their ends. The apparatus further includes discharge nozzle means to introduce the pimiento/binder mix onto the recessed area of the lower belt, the leading nip between the upper and lower belts being downstream of said nozzle means.

Abstract: This invention resides in the discovery of a fluent food emulsifier concentrate comprising a normally liquid partial glycerol ester food emulsifier vehicle in which is stably dispersed ethoxylated fatty acid esters and solid phase fine crystalline food emulsifier components, said concentrate being mechanically dispersible into a comestible mixture for the emulsification thereof. The present invention is particularly suitable for the preparation of a stable fluid shortening containing the emulsifier concentrate and a liquid edible oil suitable for bread and dough mixtures providing both dough conditioning and anti-staling properties. In an example of the present invention, the fluid concentrate comprises a fluent monoglyceride such as glycerol monooleate admixed with ethoxylated mono- and diglyceride and a solid phase ester emulsifier such as a succinylated mono- and diglyceride, or the alkali or alkaline earth metal salt of an acyl lactylate.

Abstract: A process for the synthesis of perfume products, Vitamin E and intermediates described herein involving a coupling reaction. For instance, a process for the synthesis of dehydrophytol and Vitamin E comprising forming a C.sub.15 acetylene from hexahydropseudoionone and then coupling said acetylene with 1-acetoxy-4-chloro-3-methylbut-2-ene to form a C.sub.20 acetoxy-enyne. The latter is readily subjected to partial hydrogenation and saponification in that order to form a dehydrophytol, a useful intermediate for the synthesis of Vitamin E and other products.

Abstract: An antenna consisting of three separate members, two members which are oriented perpendicular to a ground plane which function as short monopole antennas and a third member parallel to and above the ground plane which functions as a single conductor transmission line above ground, top-connecting the two antennas. One of the monopole antennas is connected to the ground plane through a terminating resistor and the other monopole is connected to the ground plane through an impedance matching transformer. The antennas mount on a ground plane, an electrically conducting surface such as the roof of a vehicle, aircraft or other suitable surface, and take an aerodynamic shape. The antenna exhibits a cardioidal pattern over an azimuth angle of approximately 120.degree. and is especially applicable for use in a multiple antenna arrangement in the application of direction finding systems. The antenna is useful over a wide range of frequencies without adjustment, because of its broad bandwidth, which exceeds 100:1.

Abstract: In a process for the manufacture of a lithographic printing plate having a paper base and a lithographic printing surface thereon comprising a resinous coating, lower coat weights leading to high coating speeds can be obtained by first smoothing the base to not substantially greater than about 150 Sheffield units, then size-pressing onto the smooth base either a barrier coat for the lithographic printing surface or a single coat comprising said lithographic printing surface.

Abstract: A process for the synthesis of an acetylenic hydrocarbon from an acetylenic carbinol which involves first replacing the hydroxyl group of the carbinol with a halogen to form a propargylic halide, dehalogenating the propargylic halide to form an allene, and isomerizing said allene to the desired acetylene. The present invention is particularly useful in the synthesis of Vitamin E.

Abstract: Spent clay from the bleaching of C.sub.18+ domestic glyceride esters ("oils") is deoiled by slurrying such spent clay with aqueous alkali at a temperature of at least about 80.degree. C. and a weight ratio of water to clay of about 2-6:1 at a high "pH window" for such oil recovery.

Abstract: Imitation cheese is manufactured by a flow process from a plurality of edible ingredients comprising fat, protein, water, and flavor wherein the cheese product is set by the addition of an acidulant, in lieu of fermentation. The edible ingredients are introduced into an elongated, confined mixing zone in such a way that the acidulant and protein are in distinct and separate flow streams until in said zone, and in the zone are subjected, at a temperature of at least about 100.degree. F, to medium-to-high intensity axial and radial flow mixing. The mixing is continued until a substantially homogeneous mixture is obtained.

Abstract: There is disclosed a dry mix adapted for hydration with chilled water to provide a pourable batter which produces on baking a crust resembling traditional yeast-leavened pizza crust; a process for preparing such pourable batter, and a unitary package of one container for said dry mix in combination with one or more containers for other snack food topping ingredients are also described.

Abstract: Drying apparatus and process are shown featuring a fresh gas flow warmed for obtaining a low temperature rise in comparatively large volume by solar heat collection, then further heated and passed into drying relationship with the material to be dried.

Abstract: An improved lithographic printing plate having a lithographic surface thereon comprising a resinous coating, at least a major fraction of which is a self-insolubilizing or cross-linkable cationic resinous binder.

Abstract: Shown is an apparatus for distributing particulate material onto a conveyor belt for a dryer comprising a feed-chute which is pivotally mounted above the belt so that the discharge end of the chute laterally traverses the conveyor belt surface. The drive to pivot the chute comprises an endless chain with an adjustable linkage between the chain and chute reciprocating the chute into successive traverses with a quick return at the end of each traverse.

Abstract: A synthesis of novel Vitamin A intermediates from betaionone is described as well as a conversion of the intermediates to Vitamin A. The length of the conjugated aliphatic side chain of beta-ionone is increased while still ultimately obtaining the desired trans form of Vitamin A. In general, beta-ionone is ethynylated to ethynyl-beta-ionol, the hydroxyl of which is etherified to form an ethynyl-terminated, alkoxy-substituted, beta-ionol intermediate. The intermediate is coupled through its copper derivative with a compound like chloro-isopentenyl acetate to produce a C.sub.20 skeleton. By semi-hydrogenation, the acetylenic bond on the C.sub.20 skeleton is converted to an ethylenic bond, and by hydrolysis the terminal ester moiety is converted to a hydroxyl group. Treatment with a strong base removes the alkoxy group to produce Vitamin A.
