Abstract: 1,073,423. Data transmission. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 24, 1966 [March 1, 1965], No. 8089/66. Headings H4L and H4P. In a transmission system in which received data is sampled at greater than bit rate, the samples are passed to a circuit (12, Fig. 1, not shown) which determines whether the last N samples, stored in a shift register (18), and the present sample are, in the majority, representative of a 1 bit or a 0 bit. The result of this majority decision is compared (26) with the output of a circuit (30) which stores the state of the last-determined data bit. If the comparator inputs differ, the said present sample is passed via a gate (20) to the output-the gated samples on the output therefore representing the data received-and the majority decision arrangement is inhibited for the next N/2 or (N+2)/2 samples. This inhibition prevents noise pulses in the received data from causing erroneous majority decisions. The arrangement may be extended to multi-channel input, as described with reference to Fig. 3 (not shown).

A diaphragm assembly 28, comprises two diaphragms 36, 37 forming a chamber between them connected to atmosphere, the diaphragm 36 being connected to a vent valve member 27 which co-operates with the end of the poppet valve stem 26 to control exhaust from the chamber 28. A chamber 45 above the diaphragm 37 is connected to the inlet port 16 by a passage containing an orifice 72 and communicates with a chamber 47 through a jet 48 the opening of which is controlled by an S-shaped pilot valve member 80. The chamber 47 is connected to the outlet port 17 by a passage 63 and the outlet pressure acts on a bellows 49 to adjust the pilot valve 80 which controls the pressure in the chamber 45. This pressure acts on the diaphragm assembly in opposition to the pressure in chamber 18 to open or close the valve 26a or vent valve 27 to maintain a constant outlet pressure. The inside of bellows 49 may be subject to a loading pressure and the initial position of the bellows may be adjusted manually. A light loading spring 83 acts on the diaphragm assembly to provide a minimum pressure drop, of say 5 p.s.i. across the jet 48.

Title: Improvements in the processes of manufacturing selenium cells for photo-electric work
IPC: H01L31/18
Filed: 1924-03-31
Abstract: 236,266. Hart, R. March 31, 1924. Selenium.-A selenium cell for photo-electric use is prepared by depositing selenium crystals on a grid by sublimation, preferably in an atmosphere of predetermined composition, temperature, pressure, and humidity. The selenium is placed on a glass plate supported on a metal plate heated to about 260‹ C. or to a suitably lower temperature if the operation is performed under partial vacuum. When the selenium melts it is spread over the glass surface, and the grid is suspended above this surface at a distance of about <1>/16 in. A little tellurium or other inert substance may be added to facilitate the spreading. The selenium is thus sublimed and crystallized on the grid which is then allowed to cool, polished by rubber, heated to about 175‹ C, and sealed while hot in a glass chamber containing anhydrous calcium chloride. Selenous and selenic acids may be removed by boiling the cell in distilled water and drying prior to the sealing. Various crystal structures may be obtained by varying the duration of the sublimation and the quality of the illumination during the sublimation.
