Abstract: ABSTRACT           Axial retention of the drive shaft is provided in a fluid pressure device of the type including an internally-toothed member, an externally-toothed member disposed eccentrically therein for relative orbital and rotational movement, and a drive shaft extending into a central bore defined by the external-ly-toothed member.  The drive shaft has male splines and the externally-toothed member has female splines in the central bore, engaging the male splines. The front face of the externally-toothed member has a recess including a stop surface generally perpendicular to the axis of the device and the drive shaft has a shoulder extending radially outward and engaging the stop surface to limit the axial movement of the drive shaft into the central bore.  Wear is minimized because the mating stop surface and shoulder are rotating at the same speed and, preferably, the shoulder "nutates" with respect to the stop surface.

Abstract: Abstract of the Disclosure A pressure gauge of small size and type suitable for fire extinguisher use. Comprising the gauge is a dial plate secured in keyed registration onto the front face of the casing. A tubular stem extending laterally from the inside face of the viewing crystal is axially slotted to embrace a radial portion of a wound Bourdon tube supporting a pointer opposite the dial plate.  Rotating the crystal prior to securing it to the casing enables the tube slot to zero position the pointer at the zero graduation on the dial plate.  When secured to the casing the distal end of the crystal stem compresses an 0-ring washer for effecting an internal pressure seal between the casing and Bourdon tube thereat.

Abstract: APPLICATION FOR UNITED STATES PATENT             SPECIFICATION          METHOD AND APPARATUS FOR EVAPORATION OF MOISTURE FROM FRUIT AND VEGETABLE PARTICLES                Abstract of the Disclosure A method and apparatus for evaporating and con-densing moisture from a procession of prepared fruit and vegetable particles at subatmospheric pressures, to manufac-ture puffed, low-moisture food products.          A series of stations of decreasing pressure and increasing temperature is established within the dehydrating apparatus, and the procession of food particles is led and guided by the apparatus to pass systematically from station to station of the series for dehydration treatment.   As the particles advance through the series of stations of suc-cessively lower pressure, they encounter an oil temperature in each succeeding station which is higher, and a vapor head pressure which is lower, than in the preceding station. By the time leading particles have traversed all stations of the series, they have become puffed and dehydrated,  Then they are cooled by contact with cool oil to fix the puffed con-dition, the oil is then removed from contact with the par-ticles in a centrifuge, and the finished food particles are then removed from the centrifuge and restored to atmospheric condition, without disturbing the regular progress of entry and dehydration of the following particles of the procession.

Abstract: ABSTRACT OF THE DISCLOSURE   An optical coupler comprising an optical chamber having a reflec-tive wall.  A light emitting device, such as an LED or the end of an optical fiber, is positioned adjacent to one end of the optical chamber.  The end of a receiving optical fiber extends into the chamber from the opposite end thereof.  A light transmitting filler fills the chamber so that light emitted into the chamber by the light emitting device will reflect off the chamber wall and impinge upon the outer surface of the receiving fiber. The receiving fiber is insensitive to alignment problems due to the close proximity of the reflector and receiver surfaces and the large receiving surface area.

Abstract: ABSTRACT         The present invention relates to the preparation of titanium disulfide and more particularly to the production of stoichiometric titanium sulfide having a high degree of crystalline perfection and a controlled particle size by directly reacting metallic titanium and elemental sulfur. Particulate titanium is heated to a reaction temperature of between about 475°C and about 600°C, and the heated titanium is contacted with an atmosphere having a sulfur partial pressure substantially equal to the equilibrium sulfur partial pressure over titanium disulfide at the reaction temperature to form titanium disulfide, the titanium and sulfur being in substantially stoichiometric amounts.  The heated titanium is held at the reaction temperature to homogenize the titanium disulfide.  The stoichiometric titanium disulfide so produced is particularly useful as a cathode material in electrochemical cells, since crystal imperfections which would reduce the effectiveness of the titanium sulfide as a cathode material are minimized.
