Abstract: "RESPIRATORY CONTROL"                     ABSTRACT The present invention relates to apparatus for relief and treatment of respiratory difficulty.  Prior art apparatus is typically complex and expensive and is not well suited for use by a person while going about normal activities. Furthermore, the prior art apparatus typically in-volve mixing of exhaled and inhaled air, leading to contamination of the filtering means.  This invention provides a self-contained breathing and filtration apparatus, contained entirely within the mouthpiece, which does not mix the inhaled and exhaled air, and which can be manufactured inexpensively.  In the invention a mouthpiece contains two separate air passages with valve means for controlling inflow through one passage and outflow through the other passage, and with provision for including a filter or medication through a replaceable cartridge which is carried within the mouthpiece.

Abstract: ABSTRACT        A selective calling receiver is described having a receiver section for demodulating a carrier wave modulated by a calling signal, a decoder connected to the output of the receiver section for selectively receiving the demodulated calling signals and controlling the receiving operation and a switch for supplying power from a power source to the receiving section intermittently under control of the decoder.  This intermittent powering reduces power consumption and is typical of prior devices.  To reduce the power consumption further the decoder is also powered intermittently according to the invention.  This is done by supplying clock pulses continuously to the decoder and varying these clock pulses according to whether the set is receiving or not.  For example, the clock frequency may be made greater during the receiving period than during the non-receiving period.

Abstract: GLASS FIBER REINFORCED SYNTHETIC RESIN TUBE HAVING INTEGRAL METAL ATTACHMENT AND METHOD OF PRODUCING SAME            Abstract of the Disclosure A synthetic resin, fiberglass reinforced tubular member having an integrally attached metallic element is disclosed, along with a pres-sure gelation method of fabricating the same.  The tubular member is used in making electrical hot line tools, and to this end the metallic element is composited to the tube body without use of metallic fasteners or the like.  In practice, a preimpregnated fiberglass material is wrapped about a mandrel to present a predetermined number of layers thereof, whereupon the metallic attach-ment is temporarily affixed to the fiberglass layer, preferably by placing strips of the wrapped material against the edges of the attachment and in bridging relationship to the wrapping.  The fiberglass material is then cured to embed the attachment in the sidewall and yield a fused, void-free monolithic structure.  The preferred pressure gelation curing technique also serves to form upraised ridges of fiberglass material along the length of the attachment to further ensure creation of an essentially integral unit.

Abstract: ABSTRACT OF THE DISCLOSURE      A thermoelectric device is disclosed which comprises the formation of a multiplicity of thermocouples on a substrate in a narrow strip form, the thermocouples being formed by printing with first and second inks formed of suitable different powdered metals with a proper binder or flux.  The thermocouples are formed in series and the opposed coupled areas are melted to form an intermingling of the two metals and the strips may be formed in sustantial lengths and rolled onto a real, or in relatively short strip form and disposed in a side-by-side abutting relationship in substantial numbers to define a generally rectangular panel form with opposed ends in electrical connection.  The method of forming the panels included the steps of feeding a suitable substrate, either in a continuous roll or sheet form, through first and second printers to form the series connected multiplicity of thermocouples thereon.  From the printers the sheet or strip passes through a melter such as an induction furnace and from the furnace it passes through a sheeter, if the strip is in roll form.  The sheets are then slit into narrow stripe relative to the thermo-couples, printed thereon and the strips are then formed into a bundle.  A predetermined number of bundles are assembled into a panel form.

Abstract: SELECTIVE VAPORIZATION PROCESS AND DYNAMIC CONTROL THEREOF ABSTRACT OF THE DISCLOSURE Whole crude and residual fractions from distillation of petroleum and like feed stocks are subjected to selective vaporization to prepare heavy fractions of reduced Conradson Carbon and/or metals content by short-term, high temperature riser contact with a substantially inert solid contact material of low surface area in a selective vaporization zone. High boiling point components of the charge which are of high Conradson Carbon number and/or high metal content remain on the contact material as a combustible deposit which is then burned off in a combustion zone whereby the contact material is heated to a high temperature for return to the selective vaporization zone to supply the heat required therein. The system is dynamically controlled for fuel supply in the combustion zone by the lower hydrogen content, least valuable components of the feed. That control is exercised by controlling the temperature of the selective vaporization zone to about the minimum value which will maintain a predetermined desired temperature in the combustion zone.

Abstract: ABSTRACT A plural fluid magnetic/centrifugal-fluid seal is provided for hermetically sealing the space between a rotated shaft member and a close fitting spaced-apart stationary housing wherein the housing and the shaft are shaped to provide magnetic pole-like close clearance gap regions between their opposed surfaces.  A high viscosity ferromagnetic fluid normally is disposed in the magnetic gap region with the rotating shaft member at rest and at low rotational speeds.  A permanent magnet or electromagnet is provided which forms a closed magnetic circuit through the magnetic gap region with the high viscosity ferromagnetic fluid.  A circumferentially arranged centrifugal seal forming region is radially disposed outward from the magnetic gap region and is located between the ro-tatable shaft and the stationary housing member.  A low viscosity centirfugal sealing fluid is disposed in the centrifugal seal forming region and is centrifugally thrown outwardly during high speed rotation of the rotating shaft member to form a centrifugal hermetic seal between the rotating shaft member and the housing at high rotational speeds of the rotating member.  The seal is designed to pro-vide a reservoir for the ferromagnetic sealing fluid in a space intermediate the rotating shaft member and the stationary housing member for collecting the ferromagnetic fluid during high speed rotation of the rotating shaft so as to keep the two different viscosity sealing fluids isolated one from the other is separate but communicating spaces.  In certain designs it is possible to use the lubricating oil of an apparatus or machine as the low viscosity centrifugal sealing fluid by providing fluid passageways between the machine lubricating oil cooling and supply system and the centrifugal seal region whereby the centrifugal seal serves as an auxillary lubricating oil pump for pumping the lubricating oil from the centrifugal seal region to a lubricating oil reservoir that comprises a part of the lubricating oil supply system.  Such an arrangement can be included in combination with a conventional pressurized labyrinth seal positioned on the rotating member adjacent the plural fluid magnetic/ centrifugal seal in a location between the plural fluid magnetic/centrifugal seal and a hostile high pressure atmospher

Abstract: Case 5781 RAILROAD CAR TRUCK     ABSTRACT OF THE INVENTION    A railroad car truck includes a pair of spaced side frames carrying therebetween a transversely positioned bolster.  Ends of the bolster are positioned within a window formed in each side frame.  A connection between the side frame and bolster includes an interposed set of springs which cushions vertical movements of the bolster.  These movements are dampened by sets of friction shoes which interact with wear surfaces formed as part of the bolster and side frame.  The bolster-side frame connection also accommodates pitching and yawing movements of the bolster and pitching movements of the side frames.  These rotational movements are not cushioned and can produce substantial stresses when contact occurs between abutting structural members of the bolster and the side frames.  To maintain such stresses below the yield point of the structural members, bolster-side frame contact is restricted to areas of the bolster where the stresses may be distributed to members having sufficient strength.     -i-
