Abstract: The disclosure relates to a method of joining titanium and titanium based alloys to columbium at low pressure and low temperature, wherein a titanium foil is electroplated with layers of copper and nickel with a columbium sheet then being placed in intimate contact with the exposed layer. The materials are then heated in a vacuum to a temperature above the Ti-Cu-Ni eutectic temperature and below the beta-transus of the titanium material to provide a joining of titanium to columbium without materially altering the mechanical properties of the materials involved.

Abstract: The disclosure relates to a refrigeration system using a multi-component refrigerant wherein the heat exchanger/phase separator can be positioned in any orientation and does not operate due to gravitational forces. This is accomplished by providing a constriction at the upstream end of the refrigerant path with a capillary tube entry slightly upstream of the constriction, the amount of liquid refrigerant striking the constriction being sufficient to provide an effective liquid seal at the opening to the capillary tube to prevent gaseous refrigerant from entering thereinto.

Abstract: The disclosure relates to a non-tippable toy which is capable of rocking about an axis and ultimately resting in a vertical position and which is also capable of motion in a lateral direction by utilizing an axle having a pair of wheel-like members affixed thereto, the axle being rotably mounted in the body of the toy so that the toy is capable of rocking about the axis. The toy also includes weights secured to the bottom of the toy body by means of a spring fastener or the like to provide the low center of gravity. The toy body includes a pair of shoulders thereon, preferably surrounding the shaft, which receive components thereon designed to alter the configuration of the toy. Numerous aspects can be provided to the toy by replacing the wheels with a plurality of feet in the shape of a wheel so that the lateral motion of the toy is not impaired. Also, the wheels can be mounted on the shaft in an off-center position to provide a side to side and up and down motion to the toy during lateral motion thereof.

Abstract: The disclosure relates to a method of rapidly removing binder from a "green" body composed of metal or cermet fine particles and a carbon-containing binder wherein the debinderizing step is performed in a water saturated atmosphere to provide chemical reaction with elemental carbon, the reaction products being removed from the system.

Abstract: A portable infusion device for injecting medicinal fluids into a human or animal body by means of a positive pressure pump that is automatically operated at selected time intervals to inject accurate amounts of fluid medicine into the body.

Abstract: The disclosure relates to a kit box formed of electrostatically protective material comprising a housing of rigid material and a plurality of bins, preferably without sides formed of flexible material wherein the bins are stacked one atop the other and are releasable secured in the housing. The securing apparatus is a combination of mating locking elements in the housing and on the outer surface of the bins as well as the compressive force applied to the resilient bin structure by the housing wherein the bins are retained under compression.

Abstract: The disclosure relates to a combination lamp and night light wherein the lamp also generates the illusion of a three-dimensional scene when the night light is operated. The scene is removably secured to the lamp base to permit changing of the scene.

Abstract: The disclosure relates to a feedstock of particulate material for use in formation of articles therefrom, the feedstock including a homogeneous combination of large particles, small particles and a binder. The large particles comprise less than about 60% by volume of the feedstock and are defined as particles having a diameter greater than their diffusion length. The fine particles and binder combined comprise more than about 40% by volume of the feedstock, the fine particles being defined as particles having a diameter less than their diffusion length.

Abstract: The disclosure relates to a refrigeration system wherein the evaporator of the refrigeration system is placed within a vacuum system as a "Meissner" coil previously described. Optionally it may be provided with extended surface(s). The cryosurface has a single tube passage for flow of either an evaporating low temperature refrigerant fluid for cooldown and continuous cold operation, or superheated compressed refrigerant gas for adding heat during the defrost cycle. Appropriate valves select whether cold fluid or superheated refrigerant gas flows through the tube in the cryosurface. A recuperative heat exchanger and a superheating exchanger preheat, in two stages, a cold compressed refrigerant gas stream after the gas has been rectified within the system. This superheated gas stream defrosts the cryosurface, flows back through the recuperative heat exchanger where it is recooled and then is reintroduced into the cold cascade heat exchangers.

Abstract: The disclosure relates to a circuit using a relatively inexpensive relatively slow sampling rate A-D converter which provides resolution which is far superior to that obtained normally from the A-D converter being used. This is accomplished by providing a variable delay circuit wherein the delay is controllable. The maximum delay of the delay circuit is matched to the sampling rate of the A-D converter being used. The delay is then varied so that trigger pulses for commencing a sampling cycle are commenced at different points along the wave or information signal being sampled so that, after several different amounts of delay have been provided to information initiating triggering pulses, the information signal will have been sampled at various points therealong to provide the higher degree of resolution required while still using a relatively inexpensive slow sampling rate A-D converter.

Abstract: An electronic amplifying apparatus intended for sound reproduction and for music instrument amplification wherein two parallel amplifiers, working simultaneously, each in a different class of operation, are fed from a single driver or signal source and whose outputs are combined. In the preferred embodiment at least two pairs of push-pull vacuum tubes are required and they are arranged so that one pair operates Triode Class A while the other pair (or pairs) operates Pentode Class AB (or Class B). The circuit can then be optimized so that the desirable sonic characteristics of Class A Triode operation are imparted into the Class AB (or Class B) Pentodes which actually produce all or nearly all of the power. The output power waveform has the high power and efficiency typical of Class AB (or Class B) Pentode operation but without the detrimental sonic side effects, namely, there is the complete absence of crossover or "notch" distortion, and there is a "soft" gradual onset of clip.

Abstract: The disclosure relates to a linearizer circuit capable of substantially replicating a non-linear waveform on a piece-wise linear basis by providing a pair of circuits, one capable of reducing the slope of an output circuit curve when a predetermined output level has been reached and the other capable of increasing the slope of an output circuit curve when a different predetermined output level has been reached. Such circuits are cascaded in required order and with predetermined slope parameters to replicate a non-linear curve on a piece-wise linear basis.
