摘要:
A lateral force device for displacing a towed underwater acoustic cable piding displacement in the horizontal and vertical directions having a spool and a rotationally mounted winged fuselage. The hollow spool is mounted on a cable with cable elements passing therethrough. The winged fuselage is made with the top half relatively positively buoyant and the bottom half relatively negatively buoyant. The winged fuselage is mounted about the hollow spool with clearance to allow rotation of the fuselage. The difference in buoyancy between the upper and lower fuselage maintains the device in the correct operating position. The wings are angled to provide lift in the desired direction as the fuselage is towed through the water.

An unmanned hydroplaning water surface vehicle having a gondola housing with external midway lift and control foils that allow the unmanned surface vehicle to provide lift and control in water at sufficient speed. A superstructure trimaran hull serves as a stable operation platform during low speed maneuvers or at rest. The superstructure hull encloses command and control systems capable of remote, semi-autonomous or fully autonomous control and navigation and vehicle attitude control. A plurality of mission specific payloads and sensors are positioned within the superstructure hull and gondola housing to allow for various types of missions. A strut connects the gondola housing and the superstructure hull above the waterline, as well as to provide for the passage therebetween of a plurality of transmission and control lines. The strut also mounts a rudder above propeller at the stern end of the gondola housing.

A streamlined fairing comprises an elongated leading edge tension member, elongated trailing edge member of flexible material integrally bonded to the leading edge member, and a flange member secured to the leading and trailing members for preventing relative displacements therebetween and for improving the shape stability of the fairing. The flange member has a cross-sectional width which is between about 10% and about 50% of the maximum width of the fairing and a cross-sectional length which is between about 5% and about 20% of the chord length of the fairing.

Disclosed are dry mixes for the provision of finished cakes, especially layer type, having a discrete and discontinuous pudding phase characterized by large sized pudding regions. The present dry mixes require no batter mixing or aeration but merely require the addition of measured amounts of water and baking. The present mixes comprise a cake component comprising a conventional full formulation dry mix for cakes in a particular physical form referred to as "granulated." Additionally, the mixes comprise a pudding component comprising a conventional instant pudding also in granulated form. The granulated pudding components have also been formed into larger sized pieces referred to herein as "nuggets." The granules of both the layer cake and pudding components are each essentially characterized by the physical features of (1) particle size, (2) bulk porosity, (3) density, (4) initial rates of moisture absorption, and (5) moisture content. Conventional agglomeration equipment and techniques employing moisture as the binding agent are useful herein for preparing the granulated pudding and layer cake fractions of the present invention. Providing the pudding component in the form of nuggets overcomes problems of insufficient rehydration in the provision of layer cakes with large pockets of a discontinuous pudding phase.

Disclosed are non-dairy dessert compositions suitable for the preparation of soft serve aerated frozen desserts. The compositions comprise from about 25% by weight to about 75% of a whole comminuted fruit puree, from about 0.3% to 1.5% by weight of an acid-stable whipping agent, from about 0.1% to 0.5% by weight of an acid-stable polysaccharide gum, from about 1% to about 15% of a malto dextrin bodying agent, from about 12% to about 28% of a nutritive carbohydrate sweetening agent, and from about 1% to 10% of an edible fatty triglyceride oil. The moisture content of the dessert compositions ranges between about 45% to 75%. After homogenization of the dessert compositions, an aerated frozen, soft serve dessert having a density of 0.2 to 0.95 g./cc. can be prepared in conventional aerated frozen dessert equipment.

Non-dairy dessert compositions suitable for the preparation of aerated frozen desserts by either commercial agitated freezing or by at-home static freezing. The compositions comprise from about 35% by weight to about 80% of a specially prepared cooked fruit base, from about 0.3% to 1.5% by weight of an acid-stable whipping agent, from about 0.05% to 0.5% by weight of an acid-stable polysaccharide gum, from about 1% to about 15% of a malto dextrin bodying agent, and from about 1% to 10% of an edible fatty triglyceride oil. The moisture content of the dessert compositions ranges between about 45% to 75%.

The present mixes comprise a cake component comprising a conventional full formulation dry mix for cakes in a particular physical form referred to as "granulated."

The granules of both the cake and pudding components are each essentially characterized by the physical features of (1) particle size, (2) bulk porosity, (3) density, (4) initial rates of moisture absorption, and (5) moisture content. For the layer cake component the particle size of the layer cake granules essentially ranges from about 0.9 to 3.0 mm. The bulk porosity essentially ranges from about 0.55 to 0.64. The density essentially ranges from about 0.45 to 0.70 g./cc. The rates of initial moisture absorption essentially range (at 70.degree. F.) from about 0.055 to 0.075 gram of water per gram of mix per second. The moisture content is less than about 5%. For the pudding component, the particle size essentially ranges from about 2.8 to 3.4 mm; the bulk porosity ranges from about 0.50 to 0.65; the density ranges from about 0.5 to 0.7 g./cc; the initial rate of moisture absorption from about 0.060 to 0.080 g. H.sub.2 O/g. mix-sec., and a moisture content of less than about 5%. Conventional agglomeration equipment and techniques employing moisture as the binding agent are useful herein for preparing the granulations of the present invention.
摘要:
A paravane includes an elongated fuselage; a wing section of spaced wing bers attached to an intermediate portion of the fuselage; stabilizer fins for maintaining the paravane lined-up with the direction of tow; a depth control flap positioned adjacent the wing section and having a pivot axis extending closely adjacent to the towing point; and depth control means for controlling the position of the control flap. The wing members have a straight leading edge portion, a straight trailing edge portion and a curved intermediate portion wherein the wing members are arranged such that the chord lines extend at oblique angles with the longitudinal axis of the fuselage and such that the resultant hydrodynamic lift force vector acting on the wing section passes through the tow point.

Components of a flexible fairing shroud are attached adjacent their leading edges to bushings through which the fairing shroud is angularly displaced about a protectively surrounded structure exposed to a fluid medium. Inflow of the fluid medium is thereby accommodated in a direction resulting in inflation of the fairing shroud to a desired streamline shape established and maintained between leading and trailing edges during flow of the fluid medium to substantially reduce vibrations otherwise induced by such flow.
