Filed: 1925-01-21
Abstract: 228,169. Westinghouse Electric & Manufacturing Co., (Assignees of Thomas, P.). Jan. 25, 1924, [Convention date]. Addition to 207,182. Microphones and variable resistance transmitters; telephone systems and apparatus. - Means are provided for limiting the mean current through the glow - dischange microphone claimed in the parent Specification. Alternating current is supplied from a source 7, stepped up to about 4,000 volts by a transformer 6, and rectified, conveniently by a full-wave thermionic discharge rectifier 5. A filter 4 is used to smooth out the current. The current is supplied to a constant current device 3 in which the cathode 12 and anode 11 are sealed in at opposite ends of the tube and a band 15 connected to the positive lead encircles the container. The voltage applied to the device 3 is considerably in excess of that required for saturation, so that variations in voltage do not affect the current supplied to the glow discharge microphone 1. This current is kept just above half a milliampere. Below this value the discharge becomes unstable, and above this value the sensitivity of the inicrophone decreases rapidly.

Filed: 1930-01-22
Abstract: 343,704. Light - curreat relays. COVENTRY AUTOMATIC TELEPHONES, Ltd. and PUCKETTE, C. C., of General Electric Co., Stoke, Coventry. Jan. 22, 1930, No. 2223. [Class 38 (v).] The shouldered core 1 of a relay is secured to the L-shaped yoke 2 by a screwed sleeve 11 passing out through a clearance hole in a bar 5 to which the yoke is secured by screws 6, insulating material 8 separating the yoke and supporting bar. When the sleeve 11 is unscrewed by means of a screwdriver slot in its outer end a shoulder on the sleeve engages the plate 8 so that further unscrewing of the nut 11 forces the core away from the heel-piece and expels it from the yoke. Thus the removal of the core is facilitated while the relay remains in situ. Similarly in replacing the core and winding the shoulder on the screwed sleeve bears on the yoke-piece to force the core into position. In a modification the shoulder on the sleeve 11 may be trapped between the yoke-piece and a plate such as an insulating plate, which is secured to the yoke-piece and forms part of the relay structure.

Abstract: 687,534. Strip-feeding device for autographic registers &c. SMITH & SON, Ltd., W. H. Jan. 29. 1951. No. 2239/51. Class 16. A strip feeding for an autographic register or other recording apparatus device comprises a main feeding device for intermittently advancing the strip and an auxiliary feeding device engageable with the strip at widely spaced longitudinal points for temporary feeding engagement therewith during initiation of each successive feeding movement. The main feeding device, comprising a hand-driven wheel 11. having pins 10 thereon engaging longitudinally spaced holes at the side of the strips 8, which run between strips of card or paper fixed on the writing surface 3 of the device, is supplemented during initial movement of the wheel 11 by pins 16, transversely displaced from the pin 10 and mounted on a resilient metal strip 18. The strip 18 is spring loaded towards the back of the device and is slidably mounted on the underside of the writing surface 3. Further pins 23 are provided at the other end of the strip 18: The strip 18 is moved by the action of a pawl 26, fixed on the shaft of the wheel 11, and which engages a dog 25 on the material of the strip 18. The pins 16 are disengaged from the strips 8 by the actions of cams 27 along the surface of which the metal strip 18 runs. The cams 27 have a larger radius of curvature than the wheel 11 so that after the initial movement the dog 25 is released by the pawl 26 and the strip 18 returns to its original position whilst the wheel 11 continues to be rotated. The pins 23 at the other end of the strip 18 are released from engagement from the strips 8 by the motion of ears 29 stamped out of the strip 18 on cam surface 27<SP>1</SP>' formed on the underside of the writing surface.

Abstract: 138,125. American Coke & Chemical Co., (Assignees of Roberts, A.). June 22, 1916, [Convention date]. Coke ovens.-In a regenerative oven, air is supplied continuouslyto burners arranged at the top of the heating-wall, and the waste gases are exhausted from one or other end of a collecting-flue at the bottom, according to the position of a reversing-valve mechanism. Two regenerative chambers 29, 30 are arranged longitudinally beneath each oven, and are connected at one end to tunnels 31, 32, and at the other to flues 47, each of which can be put into communication, according to the position of the valves 45, 49, with either a downtake 20 leading from a waste gas collecting-flue 18 beneath the sole of the oven. or with a flue 51 leading to an uptake in communication with a recuperator wall 13 between the, heating-walls 10, 11 of adjacent ovens. In the position shown of the valves, air is supplied to the tunnel 31 and passes through the regenerator 29 and left-hand flue 47, past the valve 49, and through the connexion 51 and the uptake to the recuperator wall. The waste gases from the flue 18 descend through the right-hand downtake 20, and flow past the valve 45 through the connexion 47 and regenerator 30 to the tunnel 32. The two tunnels are connected at one end through reversing devices with a stack and a source of air supply. At the upper end of the recuperator wall the air passes through damper-controlled ports to a mixing-flue 21 supplied with gas through ports 22, and the mixture descends through damper-controlled ports 24 to the two heating-walls on opposite sides of the recuperator wall. Direct flow of air through the regenerator chambers is prevented by baffles 53, 54, 55.

Abstract: 865,866. Photo-cells. MINISTER OF SUPPLY. April 23, 1956 [Jan. 26, 1955], No. 2403/55. Class 37. A photo-conductive cell having a sensitized layer of a photo-conductive lead salt supported on an insulating surface in an evacuated envelope, and a glass window in the envelope for transmitting radiations incident upon the layer, is characterized in that the inner surface of the window is in contact with the surface of the layer. After the lead selenide layer 1, Fig. 2, has been deposited and while the cell is being evacuated, a torch is arranged to heat the side 8 of the envelope (which is initially spaced from layer 1, Fig. 1, not shown) until it softens and collapses on to the layer 1. Overheating of the layer is avoided by applying cooling air through a tube 11 and by making the envelope sufficiently thin to limit the heat stored at its plastic temperature. If the layer is prepared by a process requiring a final baking, the final baking time may be reduced so that the effect of the heat carried to the layer by the collapse of the envelope is to complete the baking process. When the envelope has been collapsed it is possible to position optical devices closer to the layer 1 than would otherwise be possible. Specification 834,658 is referred to.

Filed: 1970-01-19
Abstract: 1299772 Sulphuric acid BOLIDEN AB 19 Jan 1970 [23 Jan 1969] 2425/70 Heading C1A Sulphuric acid is made by the contact process in which an SO 2  containing gas, and obtained by burning sulphurous material with air in a furnace, is introduced into a contact apparatus wherein the major portion of the SO 2  is catalytically oxidized to SO 3 . This gas is then introduced into an absorption tower, where SO 3  and some SO 2  is absorbed in sulphuric acid. The sulphuric acid is then introduced into a ventilation tower, where it passes counter-current to air which takes up absorbed SO 2  from the sulphuric acid. The stripped sulphuric acid is then recycled to the absorption tower. The sulphurous material is usually sulphur, sulphur pyrite or other sulphide material. The air may be preheated, up to 350 C, before introduction into the ventilation tower, and the air from the ventilation tower may be partly conveyed to the combustion furnace and partly to the contact apparatus. The acid leaving the absorption tower may be diluted before being fed to the ventilation tower.
