[Classes 39 (i) and 40 (v)] In an ultra-short wave electron discharge device of the kind set forth in Specification 523,712 wherein an electron beam is modulated in velocity by a longitudinal electric field so that density modulations or bunches of electrons are produced, the operating characteristics are adjustable, the device being usable as a self oscillator amplifier or detector. Hollow resonator shells 41, 42 are movable through rings 4, 5, which form part of the envelope; the shells 41, 42 are slotted to enable them to be flexed and thereby change the distances of their end faces apart. The rings are carried by bellows 2, 3 from a central shell 1 and have sealed thereto glass ends 8, 9. Toggle links 35, 36, which bear (i) on the rings 4, 5 and (ii) on abutment rings 28, 29 supported on ball races, are moved by independent micrometer screws to adjust the shells 41, 42; these-termed " rhumbatrons "-have end plates 43, 44 with grids 45, 46 and holes 85 in plates 44. The shells also have central projections 47, 48 with grids 49, 50 on their ends; these have tubular projections extending into an aligning recess in a bracket in the central shell 1. A concentric line 55 extends into each resonator shell 41, 42 with a loop 57, 58; this line 55 has a wire wrapped around it by means of which it may be turned from a third micrometer screw through suitable leverage. The indirectly heated cathode 65 is carried on a water cooled bolt 12 ; a co-planar surface 68 with ring 67 is used to form the electrons into a beam passing through the grid 45 and thence through grids 49, 50, 46. Grids 72, 73 and 74 with a hole 75 are placed beyond the grid 46 and a fluorescent screen is mounted in the glass end 9; the grid 72 directs electrons from the grid 46 to grid 73 but may be omitted. As an amplifier, modulated high frequency signal may be fed through the loop 81. As a transmitter, radiation takes place through holes 85 in the end plate 44 of shell 42 ; as a detector, radiation may be received by the same holes 85 but preferably through holes in the end plate 43 of shell 41. Biasing potentials are supplied from a battery 86. The bunching of electrons is obtained in the manner described in Specification 523,712. Energy from shell 42 is transferred back to shell 41 through the loops 57, 58 and line 55, the amount being variable. Velocity analysis may be effected by subjecting that part of the stream that passes through the hole 75 to a magnetic or electrostatic force within the end 9 and observing a track on the screen 76 as described in Specification 530,785. Specification 517,264 also is referred to.

Title: Improvements in or relating to the manufacture of new organofluoro-siloxane products
IPC: C08G77/24
Filed: 1947-06-20
Abstract: An organofluorosilane of general formula RFSiX2, where R is a hydrocarbon radicle and X is a readily hydrolysable group such as a halogen atom, a hydrocarbonoxy radicle or an amino group is hydrolysed under moderate hydrolysis conditions to give organofluorosiloxanes containing the structural unit <FORM:0627800/IV (a)/1> where n is a whole number greater than 1.  A mixture of organofluorosilane and non-fluorinated organosilane may be cohydrolysed.  The products vary from thin liquids to hard solids, e.g. where the organic radicle is a chain of 12 or more carbon atoms, they may be waxy or rigid solids.  Hydrolysis may be effected by water at ordinary or elevated temperature and may be at boiling point in the presence of an inert solvent such as an ether, a hydrocarbon, or halohydrocarbon.  Acid catalyst may be used.  Mild oxidation or heating at 50-200 DEG  C. of the initial polymers (e.g. with 10 or less silicon atoms per molecule) increases polymer size and eventual formation of insoluble resins. Thin films of the liquid polymers exposed to air at ordinary temperatures are converted to tack-free solid films.  They may be used to coat metals, ceramics, textiles, paper and as fungicides and hydrophobing agents.  On vigorous hydrolysis as with alkali, or by treatment with metal alcoholates or metal carboxylates, the fluorine atoms in the fluorosiloxanes may be replaced by oxygen or organic radicles to provide a wide variety of siloxanes. In examples the following were hydrolysed by water: (1) a benzene solution of phenyl trifluorosilane; (2) a toluene solution of octadecyl trifluorosilane; (3) a benzene solution of phenyl diethoxy fluorosilane in the presence of HCl; (4) a benzene solution of ethyl dichlorofluorosilane, and the following were hydrolysed by treatment with tertiary butyl alcohol; (5) a mixture of 1 gram of phenyl dichlorofluorosilane and 19.3 grams of phenyl ethyl dichlorosilane; (6) tolyl dichlorofluorosilane.
