United States Patent: Antenna Guy Fitting, Robert Katz
United States Patent: Antenna Guy Fitting, Robert Katz
Robert Katz Publications
The invention to be hereinafter described relates to coupling devices for the attaching of fixed wire antenna to aircraft.
Heretofore, it has been the general practice to make connections between the fixed wire antenna and aircraft by wrapping the antenna wire about a thimble or like device, as in making a splice.
This practice resulted in a number of sharp points and rough surfaces whose susceptibility to corona discharge is well known. This corona discharge resulted in bad weather extremely difficult or dangerous due to interruption of radio navigation and communication services.
The present invention is designed to overcome the …

Application Of X-Ray Technique To The Detection Of Internal Insect Infestation Of Grain, Max Milner, Milford R. Lee, Robert Katz

During the course of a comprehensive investigation of methods for the determination of internal insect infestation in commercial wheat, radiographic techniques have been developed at this station which provide satisfactory delineation of internal infestation. We have applied these techniques to the observation of the growth of such insects as granary weevil, Sitophilus granaries L., and rice weevil, Sitophilus oryza L., from the hatching of the egg within the kernel through larval and pupal growth to emergence as a mature insect. Although considerable detail is always lost in the reproduction of radiographs during engraving and printing, the accompanying figures (1, …
A Simple Experiment On Heat, Robert Katz
A Simple Experiment On Heat, Robert Katz
Robert Katz Publications
This experiment requires apparatus consisting of two ring stands, two bunsen burners, safety matches, a sheet of hard asbestos board and a sheet of aluminum of approximately the same dimensions (6 in. long by 3½ in. wide by ⅛ in. thick). The ring stands are set side-by-side with the sheet of aluminum on one and the sheet of asbestos on the other. Two matches are placed on each sheet; one in the middle directly above the bunsen burner and one on the edge, two or three inches away. In what order will the matches catch fire after the burners are …

Line intensities in the conversion electron spectra of Te121 and Te123 were evaluated in a variable field, 180° focusing beta-ray spectrograph. Electron-electron coincidences were obtained between the transition pairs 82-213 kev in Te121 and 88.5-159 kev in Te123. Decay schemes for the two isomers are shown.
