Title: Arrangement for changing-over the direction of transmission in two-way loud-speaking systems
IPC: H04M9/00
Filed: 1945-09-18
Abstract: 599,406. Two-way loud speaking systems. AUTOPHON AKT.-GES. Sept. 18, 1945, No. 24109. Convention date, Oct. 21, 1944. [Class 40 (iv)] In a two-way loud speaking system the speaking direction is changed immediately after the end of a speech train, but provision is also made for breaking in. In the system shown the relays ML, LM have their two coils wound in opposition so that if current in coil M predominates contact m is made and if current in coil L predominates contact l is made. The coils L and M are fed respectively from the rectified outputs of the receive and transmit amplifiers ALa, AM. The relays have also a neutral position in which neither contact l or m is made. In the state immediately after the subscriber at ST2 has finished speaking relays RC and TR will be released at ST1 and operated at ST2, the contacts of these relays at the latter station being shown in the operated position. Speech currents from ST1 by closing m operate TR at ST1 and by closing l release TR at ST2. When the subscriber at ST1 stops speaking m and l release at ST1 and ST2 respectively thereby operating RC at ST1 and releasing RC at ST2 to change the speaking direction. If the subscriber at ST2 interrupts the subscriber at ST1, LM at ST2 is neutralized and l opens the circuit for RC which changes the direction for ST2. Incoming speech from ST2 neutralizes LM at ST1, m opens and RC operates to change the direction for ST1. The microphone M and loudspeaker La may be combined into a single two-way electro-acoustic transducer. If desired, the possibility of feed back in the equipment may be further eliminated by frequency changing in one direction.

Inventor: WILSON PETER JOHN
IPC: B23D63/00
Filed: 1967-11-24
Abstract: 1,192,932. Making saws. JAMES NEILL & CO. (SHEFFIELD) Ltd. 21 Feb., 1969 [24 Nov., 1967], No. 24119/67. Heading B3A. A method of making a bimetallic hack-saw blade blank comprises welding edge-to-edge a strip of high speed steel and a strip of carbon steel, the strip of high speed steel being at least four times the width required for the hard edge of the blade, shearing off the surplus width of high speed steel and welding it to another strip of carbon steel and repeating the shearing and welding until all the high speed steel has been used. When the width of high speed steel has been reduced to, say, 6 times the width of a hard edge a second strip of carbon steel may be welded to the other edge of the strip of high speed steel to hold it and/or prevent it bending during shearing. In an alternative embodiment both edges of the high speed steel strip have carbon steel strips welded to and then sheared from them until the width of high speed steel is reduced so as to require one carbon steel strip to be used as a support strip. The welding is preferably performed by the electron beam process, and the shearing by a guillotine, discs or by rollers.

Abstract: 378,222. Gas condensing and washing processes and plant. STILL, C., Recklinghausen, Westphalia, Germany. Aug. 29, 1931, No. 24375. Convention date, Aug. 30, 1930. [Class 55 (ii).] Gases withdrawn by suction from the interior of the charge in coal distillation are cooled in stages to obtain oily condensates separately. Gas mains 7, 12 are connected respectively to the free space 5 and suction tube 9 of a retort 1 for the withdrawal of two kinds of distillation gases. The gases collecting in the tar main 12 pass through countercurrent water coolers 34, 35, to an impact separator 41 before passing to washing towers 68, 69 and 81, 82 for removal of ammonia by washing with water, and removal of light oil by scrubbing with wash oil, respectively. The gases then pass to storage through an offtake 127. Behind the impact separator 41, a centrifugal exhauster 44 and a condensate separator 45 are inserted. Each cooling stage results in obtaining separate oils which collect in containers 48, 49, 52 and contain respectively up to 3 per cent, 8 percent. and 25 per cent of light oils. The tar oil content of these containers may be used in the benzol washers 81, 82, and for this purpose is conducted via pipe lines 108, 110, 92 to a still 95 for separation of the washing and light oils. The main 12 and free space 5 of the retort are cleansed by flushing with warm ammoniacal liquor collected in a separator 22 from the preliminary cooling of the gases and re-circulated through pipes 28, 30, 31. The gases taken off from the free space 5 are subjected to the usual purification processes.
