Abstract: Abstract of the Disclosure A partition formed of two spaced panels forming outer wall surfaces.  The partitions are spaced by a paper honeycomb structure, passages in the honeycomb being substantially per-pendicular to the panels.  There are elongated H-shaped members fitted on each of two opposite ends of the panels, the H-bar of the members being adjacent the panel end edges.  There is a partition stabilizing bar extending centrally between the panels and extending through a space between two sections of the honeycomb. The stabilizing bar is threaded at both ends and secured to and through the H-bars of the H-shaped members so as to prevent bowing or collapse of the partition in the direction of the bar.      The method includes the steps of putting the partition together, particularly the steps of inserting the stabilizing bar between the honeycomb sections after they have been se-cured between the panels and of securing the stabilizing bar to the H-shaped members.

Abstract: RACKET SPORT TRAINING DEVICE    ABSTRACT This Invention relates generally to training devices which make it easier for a player to learn correct strokes in any of a multiplicity of racket sports.  Racket games such as badminton, tennis, racket ball, and squash are enjoying unparalleled popularity among those persons fond of the active participant sports.  Every year hundreds of thousands of people take up a racket for the first time to play one of these health and invigorating games.  Among these multitudes, there are many people who wish to attain levels of achievement in the sport greater than that of a casual player.  Unfortunately, such training usually mandates that the player find a top notch instructor, of whom there are all too few.  The present in-vention overcomes this problem by providing a racket sport training device (10) for a player to use against a flat surface (42) (such as a wall), and including an elongated shaft (12), a handle (14) attached to one end of the shaft, and a ball (16) or other rotatable member (16') attached proximate to the other end of the shaft.  The rotatable member (16, 16') is adapted to contact and follow the flat surface (42) in order to guide a racket sport player through the correct arm and wrist motion for the racket ball sport being practiced.

Abstract: APPARATUS FOR MEASURING MICROWAVE       ELECTROMAGNETIC FIELDS     ABSTRACT OF THE DISCLOSURE     A microwave signal is transmitted from a transmitting antenna through a transfer medium to an electrically modu-lated and mechanically spun microwave scatterer.  The scatterer may include an electric field responsive antenna, such as a dipole, for measurement of the electric field, or a magnetic field responsive antenna, such as a loop, for measurement of the magnetic field.  An impedance within the scatterer is electrically modulated at an audio frequency, and the scat terer is mechanically spun at an angular frequency substantially below that at which it is electrically modulated.  The scatterer thereby re-radiates to a receiving antenna a signal at the microwave source frequency which is modulated at both the frequency of electrical modulation and the mechanical spinning frequency of the scatterer.  Signals from the microwave source and from the receiving antenna are combined to yield an output signal having a magnitude which is a function of the magnitude of the field received by the scatterer and which is phase shifted proportional to the phase shift of the microwave signal from the transmitting antenna to the scatterer and thence to the receiving antenna.          The output signal may be compared with a signal coherent with the frequency of rotation of the scatterer to determine the tilt angle of the electric or magnetic field received by the scatterer.

Abstract: VENTURI DISPERSING FEEDER       Abstract of the Disclosure A Venturi dispersing feeder particularly suited for utilization as part of a flash drying system, and through the operation of which wet material is introduced into a hot gas stream far purposes of effecting the rapid evaporation of the moisture in the material.  The subject Venturi dispersing feeder includes a feeder body, which functions as a housing for rotor means.  The latter rotor means is equipped with a multiplicity of blade means suitably mounted thereon for rotation therewith.     The feeder body further has formed therein inlet means, connec-table in fluid flow relation with a source of wet material and operable for feeding the wet material therethrough into the feeder body,and outlet means, connectable in fluid flow relation with a stream of hot gases and operable for discharging the wet material from the feeder body into the stream of hot gases in substantially parallel relation to the path of flow of the latter.  The feed inlet means and the discharge outlet means are each oriented relative to the major axis of the feeder body so as to bear a tangential relationship to the path of rotation of the blades means that are mounted on the rotor means.  Through the action of the blade means, the wet material entering the feeder body through the feed inlet means is mixed therein, and agglomerates contained in the wet material are disintegrated.     Thereafter, the wet material is discharged from the feeder at a high velocity in a non-agglomerated form through the discharge outlet means thereof into the path of flow of the stream of hot gases whereupon, in the presence of the hot gases, rapid flash drying of the wet material takes place.  The feeder body is suitably supported on a base.  The latter base is provided with adjustment means operative for effecting adjustments in the angle of discharge of the wet material from the discharge outlet means relative to the path of flow of the stream of hot gases so that the wet material leaving the discharge outlet means can be made, through adjustments in the angle of discharge thereof, to enter the hot gas stream with the desired orientation relative thereto, i.e., in substantially parallel relation to the path of flow thereof and in coincident relation therewith.

Abstract: ABSTRACT OF THE DISCLOSURE           The shroud or stationary housing for the impeller of a centrifugal compressor includes inherent means for selectively controlling the displacement thereof during operation of the centrifugal compressor, and in a manner to substantially maintain uniform spacing or clearance between the shroud and the blade tips of the rotating impeller in order to achieve improved performance at both part and full power operating conditions.          The shroud is preferably formed of a unitary member including an annular, concave disc portion substantially corresponding to the configuration of the tips of the blades of the impeller, with the annular concave disc portion being rigid and connected to a fixed flange support portion by a flexible, annular diaphragm which extends generally perpendicular to the shaft of the impeller.  The annular diaphragm is sufficiently flexible such that during operation of the centrifugal compressor, the dif-ferential thermal and pressure forces generated along the length of the blades within the compressor cause deformation of the flexible diaphragm and a substantially linear movement of the rigid, concave disc portion relative to the flange support portion.  The movement of the annular concave disc portion sub-stantially corresponds to the change in configuration of the blades, thereby minimizing blade tip losses.
