Title: Improvements relating to coating ferrous metal articles
Inventor: CARTER GILES FREDERICK
IPC: C23C10/22
Filed: 1963-12-31
Abstract: A ferrous metal article such as of mild steel is diffusion coated by immersing it in a molten bath containing as a transfer agent at least 10% Ca and having incorporated therein as diffusing element one or more of Mo, Zn, Ti, Nb, V, Zr, Y, Ce and Ga, the bath being maintained at a temperature of at least 800  DEG C. but below the melting point of the ferrous metal.  The bath may also contain Cr, Ni or Al, and/or, as diluents, Cu, Pb, Sn or calcium nitride.

Abstract: 1,083,469. Electromagnetic relays. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 18, 1964 [Dec. 18, 1963], No. 51589/64. Heading H2B. . The life of a sealed magnetic reed contact unit having reeds made of 0À1% carbon, 0À5% manganese, 0À25% silicon, 51% nickel and balance iron and diffusion coated with gold at their contact surfaces, is increased by repeatedly breaking a current greatly in excess of the rated capacity of the unit. In Fig. 2, an oscillator 20 having a frequency of 100 c/s. energizes the coil 18 of the contact unit 12b, 14b, the coil 25a of a mercury-wetted relay through a time delay 27 and the coil 30a of a time delay relay. The oscillator also supplies the serially connected contacts 25b, 30b, and 12b, 14b of the mercury relay, time delay relay and contact unit respectively. The contacts 25b of the mercury relay are arranged to close 250 microseconds before the contact unit 12b, 14b opens, thus ensuring that the reeds do not close under load and only carry current for 250 microseconds. After approximately 100 cycles the delay relay contacts 30b open and the treatment ceases. The current pulses used are 5 amps and the rated capacity between 50 and 200 m.A. The contact surfaces are hardened by the above treatment.

Title: Facsimile system of run-length type
IPC: H04N1/419
Filed: 1973-11-15
Abstract: 1456658 Data transmission; facsimile systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 15 Nov 1973 [15 Nov 1972 (2)] 53026/73 Headings H4P and H4F In a facsimile transmitter, black and white images are converted by horizontal scan into run length marks and spaces which are clocked alternately into respective counters from which variable length binary words are developed and transmitted. At the transmitter, from the image scanned a varying length mark signal for black and space for white is produced in a photo-electric converter (28, Fig. 5a, not shown) which are received into run length generator 13 which produces continuous signals each representing the length of mark and space signals. Connector 50 connects output terminal 48 of 1 bit eliminator 47 of generator 13 to counter 51 which counts the number of clock pulses for the first space signal during horizontal scan H1. Counter 52 is then connected and counts the number of clock pulses representative of mark signals during next horizontal scan H2, Vertical scan controller 35 produces a series of pulses which may or may not coincide with the end of a horizontal scan period and which are applied to the reset terminal of flip-flop 56, providing a 1 on Q terminal so that counter 51 is connected through 54 to shift register 58 and bit number identifying matrix 60. At this instant VSC35 produces a start pulse hence generator 61 triggers shift register 58 which receives information from counter 51. A coding matrix 59 selects one of the output terminals of SR58 in accordance with a bit number supplied to matrix 60 through which terminal and selected matrix in 59 binary code information is passed and on which a coding operation is performed for the appropriate space signal (So). A completion pulse through OR42 and generator 43 sets FF44 to 1 hence pulse generator 13 produces a run length pulse representing a space signal S1. Through pulse generator 53 and FF40, counter 51 is then cleared. At the same time counter 52 is connected to SR58 and matrix 60 whereby a selected matrix in 59 performs a coding operation for mark signal (M1). On completion, the transmitter produces successive variable length binary groups representing spaces S1, S2 et seq alternate with marks M2, M3. Vertical sync. pulse generator 15 produces a train in response to signals from terminals R, S of VSC35, also to sync. binary code generator 63 which are interleaved with mark and space coded signals. For transmission a carrier wave of 2À5 KHz identifies the leading portion of the vertical synchronizing code and 2À0 KHz the trailing portion with 2À0 KHz carrying mark and space code signals. As one counter is operating with the converter circuit while the other counts and memorizes a run length signal from the optical scanner, transmission speed may be increased without increasing horizontal scanning speed. Receiver details are described in connection with Figs. 13a, 13b (not shown) aspects of which are the subject of a separate abridgment related to divided application 22940/76.
