Abstract: Abstract of the Disclosure A pallet post, which is adapted to be positioned between a plastic upper deck and a plastic lower deck of a pallet, is disclosed.  The pallet post has a longitudinal axis, means for rotatably mounting the pallet post about the axis between the upper deck and the lower deck of a pallet, and at least three winglike arms which project radially from the axis. The winglike arms are substantially equally spaced about the axis and extend the length of the pallet post.  The pallet post has the advantage that if struck by a tine of a fork lift truck, the post tends to rotate and to deflect the tine so that it passes the post without damaging the post or the plastic decks of the pallet between which the post is rotatably mounted.

Abstract: ABSTRACT OF THE DISCLOSURE          A center-to-end type information service system utilizing the public telephone networks that are fundamental communication media of nation-wide scale is disclosed in which desired information is requested from the terminal side to the center by means of a telephone set or simplified keyboard and then delivered to and received by a TV receiver. A part of the center functions is transferred together with the exchange function to a subcenter located near the terminal.  Thus, the length of transmission path connecting the center to terminals becomes shorter and the cost of the whole system can be cut down.  A simplified character generator is provided in the subcenter, thereby diminishing traffic of the video network.

Abstract: PROCESS FOR THE PREPARATION OF THE METHYL     ABSTRACT OF THE DISCLOSURE         An improved process for the preparation of the methyl ester of 4-oxopentane-1-carboxylic acid by the reaction of acetone with methyl acrylate.  The reactants are reacted in a reaction zone in the presence of both a primary amine and/or Schiff base as a catalyst, and an acid compound to form a reaction mixture containing the methyl ester.  The reaction mixture is distilled to form a distillate containing unconsumed reactants and catalyst and a residual liquid phase containing the methyl ester. The distillate is recycled to the reaction zone, and the methyl ester is recovered from the residual liquid phase by a further distillation.  The amount of oxygen dissolved in the reaction mixture is maintained at a level below 20 parts by weight per million, and the distillation of the reaction mixture is carried out at a temperature of less than 195°C, at a pressure of at least atmospheric, and in the presence of an inert solvent having a boiling point of between 80 and 195°C.

Abstract: ABSTRACT OF THE DISCLOSURE          A plastic cap for vacuum sealing glass containers such as bottles or jars is disclosed.  The cap includes a top wall and a depending annular side wall which extends over and is adapted to be threadedly secured to the neck of a container.  The depending side wall has at its lower edge a lead-in chamfer and suitable threads adapted to engage corresponding threads formed on the exterior of the container to which it is to be secured.  In a preferred form, serrations are provided on the exterior surface of the cap for gripping purposes, and a reinforcement shoulder is located on the outer perimeter of the side wall adjacent the lower edge thereof to prevent excessive cap expansion upon application to a container.  Vacuum sealing is attained by means of two annular flanges depending from and integrally formed with the top wall of the cap.  The two flanges are so located and angled as to engage the inner and outer rim edges of the container to which the cap is applied, whereby the flanges form air-tight seals with the rim edges when the cap is screwed onto the container.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for detecting the color temperature of a source of light including first and second semiconductor photo-sensing elements are connected in series and are oppositely poled with respect to each other.  Light of predetermined colors having different spectral characteristics is supplied to the first and second photo-sensing elements.  An output signal is derived from the opposite ends of the series circuit representing the color temperature of the light source.  In a preferred embodiment, the output signal is produced by an operational amplifier having inputs, connected to one end of the series circuit, an output con-nected to the opposite end of the series circuit, and a resistance connected between the two inputs of the operational amplifier.  In one application, the output voltage is supplied to a differential amplifier which, in turn, provides first and second voltages representing the relative intensities of the light received by the photo-sensing elements.  The difference between these first and second voltages is combined with first and second color video signal components, respectively, such as color difference signals, so as to vary the levels of these respective color video signal components.  The differential amplifier has a single output for providing a white-balanced red or blue color signal voltage.

Abstract: SCANABLE  ANTENNA ARRANGEMENTS CAPABLE OF PRODUCING A LARGE IMAGE OF A SMALL ARRAY          WITH MINIMAL ABERRATIONS Abstract of the Disclosure The present invention relates to antennas which have reflector arrangments that produce a large image with minimal aberrations at the exit aperture thereof of a small feed array.  In the present arrangment, the feed array is placed at the conjugate plane relative to the exit aperture of a geometrically confocal reflector system comprising a parabolic main reflector and a parabolic subreflector so that exact imaging of the array is obtained at the exit aperture.  In such arrangements, alignment and surface accuracy errors of the various reflectors can be easily corrected by appropriately changing the phase or the position of the associated elements of the feed array.  A three-reflector arrangement having sequential geometric confocality is disclosed which also alters the focal length of the main reflector sufficiently to permit the inclusion of polarization and/or frequency diplexing means in the overall reflector system.

Abstract: PNEUMATIC TRANSPORT AND HEAT EXCHANGE SYSTEMS                 ABSTRACT OF THE DISCLOSURE           Gas-solids transport and heat exchange techniques are disclosed wherein solid particulate material is circu-lated in a "figure 8" or a circular flow path for selective contact and/or direct heat exchange with gaseous media. The particulate material is introduced into streams of gaseous media at spaced locations in the flow path and subsequently separated from the  gaseous streams following contact and/or heat exchange therewith. The gaseous streams are maintained separate from one another by loose packed bed columns of par-ticulate material formed in the flow path and used to intro-duce the particulate material into the gaseous streams. The flow rate of the particulate material is regulated by the controlled biasing of particulate material from each of the columns thereof directly into the gaseous streams, and the particulate material is circulated solely through the use of the gaseous media and the force of gravity. The particulate material is circulated in cocurrent relationship with each of the gaseous streams in figure 8 flow path systems and, in circular flow path systems, the particulate material is cir-culated in cocurrent relationship with one of the gaseous streams and in countercurrent relationship with the other of the gaseous streams. In heat exchange applications, heat transfer between the streams of gaseous media is provided as a function of the flow rate of the particulate material and the relative flow rates of the streams of gaseous media.

Abstract: Abstract A fluid pressure responsive transducer is disclosed of the kind having a thin flat vibrating diaphragm serving as a wall of a continuous pres-sure chamber for converting a variable fluid pressure magnitude directly into a variable frequency electrical signal.  The thin flat diaphragm, secured only at its periphery to the chamber, becomes progressively stiffer as it is pro-gressively deformed by fluid pressure loading more and more from its flat or unstressed position.  A dual cavity configuration of the pressure chamber is formed by a rigid divider wall with a restricted passage therethrough.  The effects of disturbing acoustic waves which might otherwise be generated in-terior of the fluid chamber or within  pneumatic lines coupled thereto are thus suppressed.
