Title: Photographic recording materials
IPC: G01T1/08
Filed: 1970-09-11
Abstract: 1309327 Uses of luminescence EASTMAN KODAK CO 11 Sept 1970 [16 Sept 1969] 43499/70 Heading C4S [Also in Division H1] A photographic material for electron beam recording includes a support bearing a radiation sensitive layer, a fine-grain scintillator layer containing fluorescent particles having an average diameter of less than 0À5 microns, which ensures low background noise, and a coarse-grain scintillator layer of fluorescent particles having an average diameter of at least 0À5 microns, by visual inspection of which the alignment and focusing of the electron beam may be checked. The coarse grain layer may either be removable before read-out, e.g. by dissolving in the processing operation when the radiation sensitive layer is silver halide, or may be located only at the beginning of each roll of film. The scintillator employed is preferably an oxazole or oxadiazole compound, e.g. where Ar is a radical which includes an aromatic nucleus, and is incorporated in a solid solution in particles of a hydrophobic polymeric carrier material-e.g. a water-insoluble resin, a polymer of styrene, a copolymer of styrene with lower alkyl acrylates, or polyvinyl benzoateby use of a mutual solvent, and homogenizing to give a particle size 0À1 to 0À2 microns average diameter for the fine grain layer particles, and 0À7 to 1À5 microns average diameter for the coarse grain layer particles. The particles are dispersed in a hydrophilic colloid, e.g. for the fine-grain layer-gelatine, cellulose, or vinyl polymer, and for the coarse-grain layer-cyanoethylated gelatine, cellulose ether phthalates, polyvinyl alcohol, or polystyrene sulphonic acid, which will wash off during processing at about 35‹ C. The preferred ratio of scintillator to solid solution carrier material is 0À2 to 10% by weight. The coarse and fine grain layers may include an anti-hardener and a hardener respectively, and silver halide grains, pigments, and colour-forming couplers may also be incorporated. The material may also incorporate an electrically conductive layer, e.g. of vaporized metal, or a terpolymer of methyl, acrylate, acrylonitrile, vinylidene chloride and acrylic acid which has been imbibed with a cuprous iodide solution. The radiation-sensitive layer may be a direct-positive silver halide emulsion, and the support a cellulose ester, paper, foil, or glass. The scintillator layer may be either over or under the radiation sensitive layer, or may be on the opposite side of the support, or more than two fluorescent layers may be employed if there is a radiation-sensitive layer on each side of the support.

Title: Data processing system
IPC: G06F17/18
Filed: 1971-09-20
Abstract: 1313816 Data processing INTERNATIONAL BUSINESS MACHINES CORP 20 Sept 1971 [30 Oct 1970] 43656/71 Heading G4A  A data processing system is programmed to generate a data compaction code for an N- character data base. A data base sample is first read into the system and from this is generated a first matrix (Fig. 4, not shown) showing the frequency with which each of the N-characters appears in the sample in each of its possible "states". (For an illustrated example of 10 characters each character may appear in 11 possible "states"-either as an initial character or following any one of the 10 characters.) For each column of this matrix (i.e. each state) the characters are then coded by a standard compaction code such as a "Huffman" code and a value is derived for the total number of bits necessary to encode all characters in that state (e.g. Fig. 5B, not shown) in the sample. Similar values are found for every possible combination of two states and difference values are computed to assemble a second matrix (Fig. 5A, not shown) which shows the number of extra bits that would be necessary in each case in encoding the sample if any two of the N+1 states is merged. The lowest value in this matrix is then selected and the two appropriate states are merged to reduce the N + 1 states to N; the second matrix is then recomputed and the process is repeated several times to reduce the number of states to a predetermined number of groups (5 in the illustrated example). The final form of the first matrix (Fig. 6A, not shown) is then reordered, i.e. each column is rearranged in numerical order (Fig. 7, not shown). Each row of the matrix is allocated an intermediate character (a-j) and mapping tables are produced to show which initial character (A-J) is represented by each intermediate character in each group (Figs. 8, 9, not shown). From the reordered matrix a new matrix (Fig. 10, not shown) is formed corresponding to the second matrix and the merging process is continued (reducing the five groups to two coding sets in the example). The intermediate characters are then assigned variable length compact code words, in conventional manner, for the two coding sets (Fig. 11A, not shown). The assignment table, the mapping tables and group and coding set membership tables (Figs. 11A, 8 and 9, 6B, 11B respectively) then comprise all the necessary data to form encoding and decoding tables for the data base which permit a most efficient use of a memory store.

Abstract: 1,032,466. Aircraft instruments. SMITHS INDUSTRIES Ltd. Feb. 20, 1964 [Nov. 20, 1962; April 25, 1963; May 16, 1963; Nov. 28, 1963], Nos. 43762/62, 16353/63, 19398/63 and 47121/63. Heading B7W. [Also in Division G1] An aircraft instrument comprises means for indicating the relationship between the forward acceleration and the rate of change of pitch to enable a pilot to control the aircraft satisfactorily particularly during different stages of the take-off, e.g. during the preliminary ground run, and the initial flight. As shown (Figs. 1, 2, 3) a signal representing forward acceleration, as measured by a pendulum type accelerometer 11, is fed to an amplifier 8 in opposition to a signal representing the rate of change of pitch, as measured by a gyro 1, the difference being indicated by a " barber's pole " type instrument 53-5. The output from accelerometer 11 is dV/dt + g sin #, where # is the pitch angle, and the second term is evaluated in a pitch altitude gyro 16, and subtracted from the accelerometer signal in an amplifier 29. Similarly, the output from pitch rate gyro 1 contains extraneous terms due to roll and yaw which are evaluated and subtracted at unit 4. The forward acceleration signal dV/dt is modified in accordance with a predetermined value of forward velocity required for climb-out, and a predetermined value of pitch angle required for lift-off, these signals being automatically added and removed in accordance with the measured instantaneous values of velocity and pitch, and modified at individual stages of the take-off procedure. For aircraft operating on Short Take-Off principles a preset minimum forward acceleration requirement is also added. In one embodiment (Fig. 6), the acceleration and pitch signals are fed to separate movable members 112, 113 of a combined meter, each member being moved up or down by its signal acting through a servomotor 118 and rack-andpinion 114, 115, so that the appropriate relationship between the acceleration and rate of change of pitch angle is obtained when the members 112, 113 stay superimposed on each other.

Abstract: 1,043,760. Variable-speed gear and control. T. YAMAOKA. Oct. 27, 1964 [June 5, 1964], No. 43778/64. Heading F2D. [Also in Division B7] A cultivator or other agricultural tractor has two hydraulic systems, controlled by a single lever 50, respectively controlling a variable-ratio belt drive and reversing gearing arranged in series between engine 1 and driving wheels 6, 6<SP>1</SP>. Movement of lever 50 in the direction G (Fig. 3), about axis I-I actuates Bowden cable 35 and lever 36 to move valve spool 34 in direction 38 permitting pressure fluid from hydraulic pump 24 to pass through valve inlet 33, chamber 47 and conduit 40 to pulley chamber 42, thereby increasing the effective diameter of pulley 9 to increase the vehicle speed. When the right-hand pulley flange has moved the required axial distance the valve body, which is movable by arm 45 engaging pulley groove 44, closes inlet 33. When lever 50 is moved in direction F valve spool 34 connects chamber 42 with reservoir 49. Pressure fluid from pump 24 is also delivered through conduit 26 to chamber 30 of pulley 12 to maintain the belt tension. On movement of lever 50 in direction I about axis II-II extension 51 of the lever moves spool 53 of valve 52 to connect pump 24 through valve inlet 55 with cylinder 60 thereby sliding gear 13, which is connected to piston 61, on splines on shaft 27 into mesh with gear 14 to drive the wheels 6, 6<SP>1</SP> through chain 18 in the reverse direction. On movement of lever 50 in direction H valve spool 53 moves to connect cylinder 60 with reservoir 49 permitting spring 62 to slide gear 13 into engagement with gear 15 and hence drive the vehicle in the forward direction through gear pair 16, 14.

Abstract: 1,032,998. Rolling; making composite billets. CARPENTER STEEL CO. Oct. 27, 1964 [Oct. 29, 1963], No. 43849/64. Headings B3A and B3M. A billet 11 of a material which is very difficult to roll, has butt welded to its leading and trailing ends a section 12 of relatively easy metal to roll. A substantial reduction in the billet is then possible in one pass since the softer metal draws the billet between the rolls where otherwise the resistance would be too great. For example, a 2¢ inch square billet of nickel alloy A1S1 685, containing 56À19% Ni, 19À45% Cr, 13À58% Co, 4À42% Mo, 3À06% Ti, 1À30% Fe, 1À28% A1 and smaller amounts of Si, C, Cu, Zr, B, S, Mn and P, has attached to its ends sections of A1S1 304 stainless steel (Cr 18-20%, Ni 8À0-12À0% &c.). The composite billet, after heating to 2180 F. in a furnace, was rolled, the temperatures before and after rolling being 2020-2040 F. and 1875-1910 F. The sections 12 may be trimmed from the billet after rolling.
