Title: Apparatus for producing ozone
IPC: C01B13/11
Filed: 1957-05-22
Abstract: 854,616. Producing ozone. CHLORATOR G.m.b.H. May 22, 1957 [May 22, 19561, No. 16272/57. Class 39(1). A plate-type apparatus, for producing ozone by continuous silent electric discharges between flat electrodes having a stabilising dielectric layer interposed between them, comprises electrodes 2, 3 and dielectric layers 5 formed as annular discs and arranged as a plate battery in a metallic tube 1 having a cooling jacket, alternate electrodes 2 having their circumferences in heat-conducting contact with the tube. The gas to be ozonised is introduced through the central apertures 7 of the discs, flows through narrow slots defined by distance pieces 6 between the electrodes, where ozone is formed, and is drawn off through exhaust channels 8 at the wall of the tube 1 which communicate with each other through recesses at the circumferences of the electrodes 2, or inversely. The electrodes. 2 perferably consist of rigid metal discs of such thickness that no substantial difference of temperature between different points of each electrode is possible. Insulating rings 4 may be provided at the inner edges of the electrodes 2 and at the outer edges of the electrodes 3. In an alternative embodiment of the invention, Fig. 2 (not shown), the electrodes in contact with the tube wall are naked and their counter-electrodes are covered by dielectric layers, the electrodes having a substantially greater central aperture than the dielectric layers so that the latter prevent spark discharges between the electrodes. The apparatus is preferably operated at a pressure of several atmospheres, e.g. 5-20 atmospheres, the width of the slots in the electric discharge zone then being 0À1-0À4 mms. The water used for cooling the tube 1 may be subjected to approximately the same pressure as the gas in the interior of the system so that the tube may have a relatively thin inner wall. The dielectric layers may consist of a material having a high dielectric constant and small dielectric losses, e.g. a material including a. titanium compound. The tube and the electrodes 2 may be connected to earth while the counter-electrodes are connected with an electric lead 9 disposed in the axial space of the apparatus.

Title: Channel vocoder
Inventor: ROTHAUSER ERNST
IPC: H04B1/66
Filed: 1966-04-15
Abstract: 1,120,706. Vocoder. INTERNATIONAL BUSINESS MACHINES CORP. 15 April, 1966 [26 April, 1965], No. 16552/66. Heading H4R. A channel vocoder which includes a number of band-pass filters to derive signals defining the spectrum of a speech signal has an integrator arranged on the output of each band-pass filter with the integration time of each integrator controlled in accordance with the pitch frequency of the input speech signal. The arrangement eliminates pitch frequency dependence of the various analysis channel outputs. Fig. 2 shows a system in which the speech spectrum is analysed by band-pass filters BP 1  to BP n  whose outputs are rectified and integrated in circuits I 1  to I n  to provide signals defining the speech spectrum. The integrators are sampled and reset by pulses on line K o , the pulses being derived from the speech pitch pulses during voiced sounds and from a constant repetition rate pulse generator IG during unvoiced sounds, switching being under the control of a voiced-unvoiced discriminator D1. In a vocoder where the excitation function is derived as a pulse train, both during voiced and unvoiced sounds, the pulses being randomly spaced within limits during unvoiced sounds, the excitation function pulses may be used to sample and discharge the integrator both during voiced and unvoiced sounds, Fig. 3 (not shown). Where the spectrum signals are to be transmitted in digital form an arrangement such as is shown in Fig. 5 may be used where the integrator has a threshold discriminator D 1  to D 1  connected to reset the integrator when the integrator output reaches a predetermined value. Each resetting produces a pulse on line e and these pulses are counted by the respective counter BZ 1  to BZ n . Each excitation function pulse is applied to store the counter count and to reset the counter to zero. If the spectrum signals are to be quantized, e.g., to eight levels, the integrator and level discriminator may be arranged so that it produces a maximum of 8 pulses on line e for the maximum signal level during the longest expected excitation function period. By using a three-stage binary counter for each counter BZ 1  to BZ n  a binary signal is obtained directly from the state of the binary counters. Excitation function pulses may be derived as shown from the speech signal during both voiced and unvoiced sounds, or the resetting pulses may be derived from an idependent generator during unvoiced sounds as in Fig. 2 (or Fig. 4, not shown). Transistor integrator circuits are described, Figs. 6 and 7 (not shown).

Abstract: 163,606. Tomlinson, C. L. June 23, 1920. Drawings to Specification. Gilding, silvering, and platinizing.-Consists in a process for producing a glass mirror having a metallic reflecting surface embedded beneath its surface. The glass used is of the kind having in its composition a high proportion of lime so that when strongly heated it resists softening of the mass while its surface becomes plastic or liquid. In making the mirror, a deposit of gold, silver, platinum, or copper is formed on one surface. The glass is then heated for a short period to such a degree that the surface only is caused to melt and absorb the deposit of metal. To form the metallic coating, dry chloride of gold, silver, platinum, or copper is mixed with oil of rosemary and made into a paste, which is thinned with oil of lavender. The paste is applied to the polished surface of the glass, which is then heated sufficiently to evaporate the oils.
