Title: Improvements in or relating to the manufacture of packings or bodies for transfer ofmoisture and/or heat
IPC: C04B41/50
Filed: 1962-01-05
Abstract: 998,132. Laminates. C. G. MUNTERS. Jan. 5, 1962 [Jan. 9, 1961], No. 483/62. Heading B5N. [Also in Divisions B1 and F4] Heat or moisture transfer components, comprising adjacent thin sheets of asbestos secured together and shaped, for example by corrugation of at least alternate sheets, so as to form passages between them, are treated (a) to remove or render innocuous organic materials such as starch and/or cellulosic fibres which are employed to bond the fibres of the sheets together and which are liable to become ignited in use and cause disintegration of the sheets, e.g. by loss of water of crystallization from the fibres, and (b) by impregnation with inorganic material to replace the material removed. Treatment (a) consists of burning of the organic constituents under controlled non- oxidizing conditions which prevent too high a rise of temperature. As shown in Fig. 2, the component comprises thin alternately corrugated asbestos sheets 40, 42 the fibres of which are bound with starch and the inclusion of cellulose fibres. The corrugated sheets provide channels 26 about 1-3 mm. in depth and are secured to the plane sheets by inorganic adhesive such as sodium silicate. The sheets are impregnated (treatment (b)) to increase their strength, before heat treatment, with calcium silicate (formed by precipitation between calcium chloride and sodium silicate), or, when used for drying or moisture transfer, may be impregnated after heat treatment with a hygroscopic salt such as lithium chloride. The laminated components may be in the form of a rotor as described in Specification 770,201. The heat treatment may be carried out in apparatus, Fig. 1, comprising an outer insulated chamber 10 containing an inner chamber 20 having a grid 30 for uniform distribution of air and a second grid 24 supporting the component 26 to be treated, the periphery of the grid being blocked off by a screen 28. Hot air is circulated through the component by a fan 34 and the temperature and combustion controlled by the admission of air through a butterfly valvecontrolled inlet 14 and the release of gases through a similar outlet 12. The invention is applicable in the manufacture of cooling towers.

Title: Synchronous data transmission systems
IPC: H04L7/033
Filed: 1972-01-07
Abstract: 1336271 Synchronizing data transmission systems SIEMENS AG 7 Jan 1972 [27 Jan 1971] 771/72 Heading H4P In a data signal receiver a scanning or sampling signal fa produced by a frequency divider FTT1 is maintained in synchronism with a data signal received at E by an arrangement in which each data signal reversal detected by circuit SU sets bi-stable K to a one state which opens gate G3 to pass to a counter SE counting pulses fz, either through gate G4 for backward counting or through gate G5 for forward counting depending upon the polarity of a reference signal fv whose frequency is the same as the scanning frequency fa but out of phase by 90 degrees. Signal f2a is twice the frequency of fa and its next positive flank resets bi-stable K to stop counting. If the scanning frequency fa is in phase with the data elements received at E the counter FE counts backwards and forwards for equal periods. Lack of synchronism produces a positive or negative count in counter FE which upon exceeding a predetermined value arising from several data elements of the received data signal provides a pulse which is directed to the frequency divider counter FTTI via gate G1 or G2 depending on the polarity of the reference signal fv to interleave or inhibit pulses in FTT1 to thereby advance or retard the phase of the scanning frequency fa.

Title: High frequency acceleration cavity
Inventor: MIURA TAKASHI
IPC: H05H13/04
Filed: 1995-01-06
Abstract: PURPOSE: To suppress a local temperature rise and multipactering discharge, and to realize an input of a large high-frequency power, by forming a cooling passage to cool locally near the opening connecting the waveguide of a high frequency cavity, around the opening, in a circular form. CONSTITUTION: The Joule heat generated by a wall current 10 to a cavity main body is removed by a cooling pipe 11 provided on the outer surface of the cavity main body. On the other hand, since the current is concentrated near an opening 5, a cooling passage 12 is formed in a circular form around the opening 15, and a cooling water is fed to cool. The cooling water fed to a feeding joint 16 flows through the passage 12 passing through a cooling water feeding port 14, and then passing through a cooling water exhaust hole 15 and an exhaust joint 17, and returns to the cooling system. Consequently, the generation of discharge following a vacuum deterioration resulting from the discharge gas from the wall surface, and the increase of the heat stress by the temperature difference can be avoided, and a large high-frequency power can be generated.
