Title: Facsimile transmission systems
IPC: H04N1/419
Filed: 1974-07-22
Abstract: 1444482 Facsimile transmission systems SIEMENS AG 22 July 1974 [23 July 1973] 32329/74 Heading H4P In a facsimile transmission system in which each length covered by an uninterrupted sequence or run of scanning points of the same colour along a scanning line is converted by pulse code modulation into one or more code words in which if the number of bits n in the first code word is not large enough to convey the length one or more further codewords are formed and transmitted along a communication channel, where more than one code word is employed for the representation of a run the second and/or third code words have a number of bits less than n. At the receiving end a number of bits in each first code word is determined on the basis of the same criterion used at the transmitting end (i.e. depending on the nature of the original to be transmitted). On occurrence of a code word of maximum value further code words are identified from the received bit sequence the individual code words are decoded and the lengths covered corresponding to different colours, such as black and white, are facsimilied An example of the sequence of the number of bits in successive code words following the first code word having n bits is n-1, n, n+1, n + 2, n + 3. Other examples are disclosed. At the transmitting end Fig. 2 a coder 1 is controlled by a pulse source 17, a scan line start circuit 19 and a comparator 3 to form the code words. A shift register 2 is controlled by the pulse source 17 and has as many stages as the number of bits in the largest code word and indicates a residual as yet uncoded remainder in the run which is to be coded. If n = 3 when the first three stages of the shift register 2 have been occupied by the first code word a comparator control 4 via control line 11 closes switches 5, 6 and 7. The comparator 3 compares the first code word with a given three bit code word (such as all ones or all zeros) which indicates if there is still any uncoded remainder in the run which is being encoded. Any uncoded remainder is notified by the comparator 3 to the coder 1 and the comparator control 4. The coder 1 produces the next code word which consists of only two bits and is fed into the first two stages of the shift register 2. Similar to above the comparator control 4 activates the control line 12 and connects the first two stages of the shift register 2 via the switches 5 and 6 to the comparator 3. The above is repeated until the comparator 3 encounters a code word indicating that the run being coded has been fully coded. The receiving end includes a pulse source (23, Fig. 3, not shown) a shift register (24), a scan line start circuit (22), a comparator (25) a comparator control 28, control lines (35-40) switches (29-34) and a decoder (26) functioning in a corresponding manner to the transmitting and such that the decoder identifies the code words.

Abstract: 1,046,009. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 7, 1964 [Aug. 9, 1963; June 22, 1964], No. 32334/64. Heading G6C. In the manufacture of nuclear fuel elements, rods of uranium metal or alloy are coated, prior to canning, with a metallic deposit which is intended to retard the attacking action on the fuel by the cooling fluid in the event of a can bursting, and to prevent diffusion of plutonium and/or its fission products from the fuel, by applying a thin sheet of coating metal or alloy over a uranium metal or alloy rod which is maintained applied thereon by continuous mechanical pressure and heating the rod in a vacuum or in an inert atmosphere at a temperature and for a period of time which are sufficient to cause diffusion of the coating metal or alloy to a predetermined depth within the rod. Suitable coating metals are copper, zirconium, aluminium, niobium and nickel, all of which are of particular value in providing protection against oxidation, and of which the latter three provide protection against the diffusion of plutonium and/or its fission products. The best results for oxidation protection are obtained with zirconium and, in order to obtain a metallurgical bond with the can, a copper layer may be deposited above a zirconium layer or a single layer of a zirconium-base alloy containing a low percentage of copper may be used. By way of example, a uranium rod is first pickled and rinsed and then rolled in a thin foil of the coating metal or alloy which has itself been previously pickled, the foil being turned over at the two ends of the rod so as to entirely surround the rod and then applied against it in a suitable appliance, such as that described in the Specification. The assembly is placed in a secondary vacuum of between 10<-5> and 10<-6> mm. Hg and heated to between 350 and 400 C. for several hours in order to ensure the elimination of gas, then heated to between 600 and 800 C. for a period of approximately 100 hours under which conditions diffusion of the cladding material into the uranium occurs so as to provide an adherent and compact layer of coating metal or alloy having a thickness of the order of 10 microns.

Abstract: 1,099,568. Magnetic recording; tape stores. WESTERN ELECTRIC CO. Inc. July 20, 1966 [July 26, 1965], No. 32563/66. Headings G4C and G5R. Successive input signals of binary information are recorded on a magnetic medium by means of a magnetic head having a magnetic gap, the magnetic medium being advanced through a distance less than the length of the gap after receipt of a first binary signal and before receipt of the next succeeding signal, so that the portion of the medium (tape as described) which was adjacent to the leading edge of the gap during receipt of the first signal remains within the gap and the magnetic condition produced in this portion by the first signal is subsequently replaced by the magnetic condition produced adjacent to the trailing edge of the gap by the next succeeding signal. The passage of the leading-edge condition across the gap produces an output from the head which may be compared with the input signal in a temporary store, for immediate verification. The recording medium may be advanced in equal steps in response to the receipt of input signals, or it may be advanced at a uniform velocity with the input signals occurring at uniform intervals. The recording process described uses the NRZI system in which polarity is changed only on receipt of a binary one and does not change for a binary zero.

Title: Improvements in precision casting
IPC: B22C9/04
Filed: 1947-12-11
Abstract: 635,959. Mould materials; moulding processes. DUESBURY, W. H., and ATKINS, C. Dec. 11, 1947, No. 32648. [Class 83 (i)] In a process of moulding, a pattern is coated with a high refractory material bound by ethyl silicate with the addition of a condensing agent and is then invested in a refractory material which is bound by cement and which is waterborne. The investment material comprises 75 to 96 per cent by weight of a refractory material such as charp, chammotte, silica flour, molochite or the like mixed with 4 to 25 per cent of ordinary cement or alumina cement. The coating comprises ethyl silicate with 1 to 5 per cent of a condensing agent such as piperidine or monoethanolamine and if desired a wetting agent with or without a volatile solvent miscible with ethyl silicate, such as alcohol, the whole being mixed with refractory material such as a mixture of potter's flint and china clay. The coating may be applied to the pattern by spraying, painting or dipping. After drying and firing, the ethyl silicate forms pure silica. In certain cases it may be desirable to apply the refractory mixed with ethyl silicate separately from the condensing agent in order to avoid gelling prior to application. This may conveniently be done by spraying simultaneously through different nozzles. After the investment has been settled by vibrators, the top liquid is poured off, the mould allowed to stand for the cement to set and the wax pattern is then melted or burnt out and the mould is fired.
