Title: Improvements in or relating to the impregnation of metals with silicon
IPC: C23C10/44
Filed: 1937-11-25
Abstract: 512,144. Cementation ; coating metals, SHEPHERD. G. R. (Ihrig, H. K.). Nov. 25, 1937, No. 32494. [Classes 72 and 82 (ii)] In a process for the siliconizing of articles made from a metal capable of cementation by silicon, such as a ferrous base article, the article, or that part of it which is to be siliconized, is placed in, or brought into, contact with silicon carbide and/or ferro-silicon in a closed chamber, heated in the absence of chlorine containing gas, e.g., under non-oxidizing atmosphere, such as nitrogen containing a small amount of hydrogen, and then a current of chlorine gas or the vapour of a chloride, other than chromium chloride, is introduced into the chamber until the desired depth of penetration of silicon is obtained. When silicon carbide is used alone, the initial heating is carried up to at least 1500‹F. and when ferro-silicon is used alone, the heating is up to at least 1600‹F., and when the chlorine &c. is introduced the temperature used is up to 1830‹F. The article may be first treated in contact with silicon carbide and ferro-silicon subsequently added. The rate of penetration of silicon into the article is regulated by regulating the rate of supply of chlorine &c. and may be at a rate which is at least equal to or less than that of the diffusion of silicon into the article. Examples of chlorides which may be used are ammonium chloride, calcium chloride, ferric chloride, manganese chloride, copper chloride, nickel chloride and sodium chloride and these may be blown into the chamber. When chlorine is used it may be mixed with nitrogen. Composite cases on the article may be formed by introducing a metal or alloy or a mixture of metals and/or alloys with or without a metal chloride into the siliconizing agent, e.g., copper which may be mixed with silicon carbide or added to a mixture of silicon carbide with copper or other chloride or stainless steel scrap may be mixed with the silicon carbide. The article may be shaped to its completed form prior to the first heating and may be rotated during the treatment. If a ferrous article is treated it should contain less than 0.05 per cent. of sulphur. The article may be heated in the non-oxidizing atmospheres with a substance obtained by mixing the residue of a previous treatment with silicon carbide or ferrosilicon. Finally, oil is applied to the siliconized layer, such oil being retained in the pores of such layer. The article may be treated so as to provide a complete impregnation of silicon.

Filed: 1962-08-27
Abstract: 1,006,016. Electronic counters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 27, 1962 [Aug. 29, 1961], No. 32799/62. Heading G4A. The stages of a binary counter respond to the beginning of a pulse to be counted whereas auxiliary elements conditioning the stages for for response are affected by the end of said pulse. The counter is made up of a number of circuits shown in Figs. 2-5. An L block, Fig. 2, operates as an AND gate followed by an inverter. A dot OR or L1 block, Fig. 3, operates so that if all the inputs are 0 the output is 1 while if any input is 1 the output is 0. Fig. 4 shows the basic bi-stable element of the counter and comprises two L blocks in which a +vegoing pulse applied to 40 sets the element and locks it in set or 1 condition. Likewise a + ve going pulse applied to 42 resets the element to 0 condition. Fig. 5 shows a driving amplifier D. Each bi-stable pair of L blocks 50, 51 of the stages 10-15 of the counter is controlled by the outputs of steering elements S1-S3 through L and L1 blocks so that according to whether the counter is set to forward or reverse operation so those stages which are to reverse at the next pulse receive a +ve-going pulse on the set or reset lead as the case may be. The change-over takes place at the beginning of the count pulse. After the change-over the counting stages control the steering elements S1-S3 through further L and L1 logic blocks so that the necessary changes are made at the end of the count pulse. Resetting. The counter resets to zero automatically. Alternatively a predetermined number set up on leads 119 can be entered when lead 117 is marked. Further the counter can reset when it attains a predetermined number, gate 121 as an example changing the capacity of the counter to 26.
