Abstract: A pressure-tight, rotary pipe coupling joins rotating, high temperature fluid transmission lines. Pressure seals of the coupling are maintained at a temperature lower than that of the high temperature or primary transmitted fluid by thermally insulating the seals from the high temperature fluid and by pumping a fluid coolant through annular cavities located adjacent the seals. A balanced pressure structure substantially eliminates thrust forces between the coupling members and reduces rotating friction.
Abstract: A braking device for a ski having two blades arranged in the shape of an inverted V resiliently hinged to a plate mounted on the rear end of a ski, the blades are adapted to pivot downwardly and dig into the snow when the ski tends to slide rearwardly. The blade closest to the rear end of the ski is narrower than the other so that it digs into the snow readily and the wider blade provides the necessary braking force.

Abstract: The shaft driven by a reversible motor for opening and closing a door is provided with at least one reflective surface. An optical source/detector senses rotation of the shaft and generates a pulse each time one of the reflective surfaces passes. A programmable counter circuit counts the pulses in one direction when the door is opened and de-energizes the motor when a predetermined count is reached without the use of mechanical switches. The counter is decremented when the door is closed, and de-energizes the motor when the count returns to zero. Any obstruction will cause the system to stop the door if sensed during opening, or to reverse the door's direction if sensed during closing. Provision is made to account for any "coasting" the door may experience due to inertia; and the system will also track and permit small changes in the closed position of the door, as might occur if snow accumulates beneath the door.
Abstract: Aqueous protein dispersions obtained from vegetable sources are subjected to successive pressure and cavitation cycling (e.g., centrifugal homogenization) at temperatures below the protein heat denaturization and under slightly alkaline pH's (e.g., pH 7.0-8.0) to provide a high NSI product. These high NSI products may be dried to provide a vegetable seed product having functional properties and utility similar to milk proteins. Buffered salt extracts from such spray-dried products reveal a predominant restructuring of the protein constituents into high molecular weight protein aggregates. Low NSI soy concentrates obtained by aqueous alcohol extraction processes are converted into a high NSI product possessing many of the desirable functional attributes of soy isolates plus those of milk proteins.

Abstract: A direct current responsive mixing circuit (10) includes three mixers (14, 16 & 18), each having one D.C. port and two A.C. ports. The D.C. ports are responsive to D.C. and A.C. signals, while the A.C. ports are responsive only to A.C. signals. One mixer (14) has an A.C. port (24) receiving a pump signal and a D.C. port (28) receiving an I input signal. A second mixer (16) has an A.C. port (26) receiving the pump signal and a D.C. port (32) receiving a Q input signal. The remaining A.C. ports of the first two mixers (14 and 16) are connected to the two A.C. ports (36 and 38) of the third mixer (18). An output signal having a component corresponding to the product of the I and Q input signals is produced at the D.C. port (40) of the third mixer (18). In this construction, the mixing circuit 10 is responsive to A.C. and D.C. input signals and may produce a D.C. output signal component.
Abstract: By the process of this invention, printed circuits are prepared containing an electrically conductive wiring trace from materials having adherent and non-adherent surface areas, e.g., printed circuit substrates bearing an imaged photoadhesive layer. Onto the adherent surface areas of the material are applied ductile metal or alloy particles, and any excess particles are removed from the non-adherent areas. The metallized areas are conjoined, e.g., with silicon carbide brush or rounded metal rod. The conjoined areas can be electrolessly plated, electroplated or soldered. Multilayer printed circuits can also be prepared by repeating these steps with additional layers of photoadhesive material adhered to underlying printed circuits.
Abstract: A draw-texturing feed yarn that is new in that it is a heather feed yarn, i.e., is suitable for draw-texturing to form textured yarns that are suitable for making fabrics having a uniform fine heather tone, comprising spin-oriented filaments of two differently-dyeable polyesters. The different component filaments are well mixed to a degree indicated by a new measurement termed DCM (Degree of Component Mixing). The different component filaments preferably have a balanced stress ratio (SR), i.e. the ratio of their stresses at the strain corresponding to the draw ratio undergone during draw-texturing is about 0.8 to about 1.2. Preferred components are homopoly(ethylene terephthalate) and cationic-dyeable copolyester. The heather feed yarns may be prepared by cospinning, with suitable arrangement of spinneret orifices and selection of suitable features, especially polymer viscosities.

Abstract: An improved low-energy detonating cord, which is light-weight, flexible, strong, and non-conductive, detonates at high velocity, and is readily adapted to high-speed continuous manufacturing techniques, has a continuous solid core of a deformable bonded detonating explosive composition comprising a crystalline high explosive compound, preferably superfine PETN, admixed with a binding agent, the crystalline explosive loading being about from 0.5 to 10 grains per foot (0.1 to 2 grams per meter) of length; and, enclosing the core, a protective plastic sheath, e.g., about 0.005-0.075 inch (0.127-1.905 mm) thick, no metal or woven textile layers being present around the core or sheath. Preferably, one or more continuous strands of reinforcing yarn, e.g., running substantially parallel to the core's longitudinal axis, are located between the core and the plastic sheath, or in or around the sheath.
Abstract: In a light-sensitive material for tanning development containing unhardened or only slightly hardened gelatin silver halide emulsion layers, the silver content required to obtain maximum density is reduced by incorporating carbon black pretreated with water-miscible compounds which have a higher affinity for carbon black than gelatin. Suitable treatment may be provided by at least two of the following: poly-n-vinyl lactams, polyalkylene oxide derivatives, water-miscible compounds containing at least two OH groups, and polyalkylene oxides with a molecular weight of at least 400.
Abstract: An improved process for the continuous chlorination in vapor phase of butadiene to a mixture of dichlorobutenes at a temperature about 90.degree.-250.degree. C., wherein chlorine is premixed with a portion of butadiene and introduced at one end of a tubular reactor, while the remainder of the butadiene, which is used in a large excess, is introduced at one or more points downstream from the point of introduction of the chlorine-butadiene mixture, the temperature and volume of this additional butadiene being sufficient to effectively cool the reacting mixture so that the maximum temperature in the reactor does not exceed about 250.degree. C. but does not fall downstream from the butadiene injection point below about 130.degree. C.

Abstract: An apparatus for supplying and attaching stiff crimpable sheet material at its selvedges to pin chains of a tenter frame includes an overfeed means for squeezing the material at each selvedge into a wavy shape and a pinning brush having a peripheral surface that corresponds to the wavy shape of the selvedge of the material. The pinning brush synchronously moves with the selvedge of the material so that the crests and valleys of the peripheral surface of the brush are maintained in alignment with valleys and crests, respectively, of the selvedge.
