Title: Foams from vinyl ether prepolymers
Inventor: CHU NING JO
IPC: C08G8/30
Filed: 1964-01-03
Abstract: Ethylenic ethers containing at least two ethylenic linkages per molecule in which unsaturated ether links are adjacent, are reacted with alcohols, polyhydric phenols, carboxylic acids, polycarbamates or polyamides to form prepolymers which are then foamed and cured by addition of acidic catalysts and volatile foaming agents.  In preferred ethers, the ether and ethylenic linkages in pairs are included in cyclic 2H-pyran ring systems linked by groups containing, e.g. ether and ester linkages.  In preferred systems there is at least one group reactive with the unsaturated ether per molecule thereof, and the foaming mixture may contain additional unreacted quantities of the reactants, preferred reaction mixtures containing 35-98% by weight of prepolymer. The foaming agent may be a halogenated hydrocarbon such as trichloromonofluoromethane and the acidic catalyst may be boron trifluoride. Surfactants such as siloxaneoxyalkylene copolymers may be used.

IPC: H04N5/073
Filed: 1972-01-05
Abstract: 1353253 Multiplex systems THOMSON-CSF 5 Jan 1972 [8 Nov 1971] 374/72 Headings H4R and H4L In a system in which a control unit is connected to a television camera by a single cable, control signals from the control unit to the cable are formed into a time multiplexed signal whose D.C. component is zero, and are fed to the cable together with a D.C. power supply. As described video signals to and from the camera are modulated to frequency bands separate from those of the time multiplexed control signals and power supply to enable transmission of all signals over the same cable. Control signals of different bandwidth are accommodated in the time multiplex signal by having different channels sampled at different rates, each sampling rate being a multiple or submultiple of the multiplex frame frequency, which is related to the frame frequency of the video signals. Time multiplexer, Fig. 2, comprises a clock generator (1) of 12,500 Hz which is phase locked to the video frame frequency of the television system by comparator (6). The clock signal feeds, via divide by 2 stage 2, serially connected counters 9 and 49 each having a count of 10. The counter output is used either direct, via AND gate 30, or via a matrix 31, to control the sampling of 45 different control signals 35 at different rates according to their respective bandwidths. The output from the sampler 33 is fed to a comparator 38, fed also with a triangular wave from ramp generator 39, to provide a pulse width modulated output which is converted at 32, by comparison with signal from divider 2, to produce, for each width modulated pulse, two pulses of opposite polarity, each of half the duration of the original width, providing a signal with no D.C. component. Synchronization of the t.d.m. signal is controlled by amplitude modulation of the output pulse stream at the picture frequency by the connection from the output of the divider 5 which is fed with frame frequency pulses and is also responsible for resetting counter 49. Demodulation is effected by a conventional counter and gate assembly, Fig. 4 (not shown). The time multiplexed control signals are added to a modulated viewfinder video signal and the D.C. power supply for application to the cable for transmission to the camera; while at the camera pseudo luminance, red, and blue video signals having field phase reference, interphone, and remote control viewfinder signals modulated on the back porch of the horizontal blanking intervals, are modulated on respective frequency multiplex channels for transmission over the cable to the control unit, Fig. 5 (not shown).

Title: Process for the manufacture of hydrobromic acid from bromine and hydrogen
IPC: C01B7/09
Filed: 1920-01-06
Abstract: 154,472. Napp, H. R., (Tschudi, A.). Jan. 6, 1920. Hydrochloric acid.-Bromine burns quantitatively to form hydrobromic acid, when it meets a heated stream of hydrogen, preferably in slight excess. The bromine, introduced through the pipe B, is evaporated in the quartz vessel A, by means of the heating elements e, in the oven H; and, rising, meets the stream of hydrogen from the pipe W, where the two gases combine forming a flame. To commence the reaction, heat is supplied by the coil R and the supplies of hydrogen and bromine are regulated when the appearance of the flame indicates that this is required. The hydrobromic acid is removed from the sphere of the reacting gases by the upward draught that is produced, and is carried to an absorption apparatus.

The received coded signals are decoded, the short-time frequency spectrum signals are brought back into the time domain through re-transformation, and finally the blocks present in the time domain are assembled. Moreover, the blocks are partitioned into sub-blocks and, in case of signal level changes from one block to the other which exceed a predetermined value, the signal parts in the sub-blocks are subjected to a compression prior to transformation and to a complementary expansion after the re-transformation. To improve the signal-to-noise ratio, the signal is amplified and/or attenuated in the sub-blocks during the compression dependent on the average signal powers in the respective sub-blocks.
