Abstract: 1,233,484. Associative stores; data processing. INTERNATIONAL BUSINESS MACHINES CORP. 26 July, 1969, No. 37665/69. Headings G4A and G4C. In an electronic digital data storage system in which data is transferred between a data register and any word register of an associative array, the word register being selected by an associative search using orders of the data register specified by a mask register, a mask store is provided having a plurality of mask data registers, the contents of one or more of which are loaded into the mask register. Different masks may be loaded during the first (selection) and second (read/write) phases of a store cycle. A control store provides search arguments for the main associative store (above), an associative function store which controls the latter, and for the mask store which is also associative (but need not be). The main store may perform table-look-up operations. The argument bit positions of the mask store have possible states 0, 1, " don't care". If two or more words are read from the mask store (or other associative store) simultaneously, they are ORed together. The main and mask stores may be duplicated, the main stores receiving the same data and same function control signals, and the mask stores receiving the same search argument. The data may include extra function bits, so by using different masks on them, the main stores may perform different operations from each other. Each main store may perform an operation (e.g. add in real-time process control applications) on a respective character of a multi-character word, by table-look-up. If no mask is selected for a given main store (due to no match in the mask store), this may inhibit the respective main store. Alternatively, data read from one main store may go to the data register of the other, optionally with interchange of selected fields. With this serial arrangement the first main store may generate partial sum and carries, and the second may add carries into the partial sum, thus performing addition by table-look-up. Main stores may have two data registers, and in the serial arrangement this allows the second store not to be used for operations other than addition by using, in these operations, the data register not communicating with the second store, the empty state of the data register of the second store signifying to it no-operation. Each data register may have a respective mask register. The control store may be non-associative and addressed by an instruction counter, or associative and using a " next " operation to get successive instructions. The associative stores may be as in Specification 1,186,703 referred to.

Abstract: 1,233,631. Bridge cranes. ASHMORE, BENSON, PEASE & CO. Ltd. 18 March, 1970 [24 Jan., 1969], No. 4116/69. Heading B8B. A gantry 1 is rigidly supported at one end on leg 2 and pivoted at the other end at 11 on leg 3. The legs 2, 3 are mounted on respective pairs of trucks 4 each having a plurality of wheels 5 running on parallel tracks 6, 7 extending normally to the length of the gantry 1. Some or all of the wheels 5 on the trucks 4 are driven to move the gantry 1 along the tracks 6, 7. The wheels 5 on either end of the gantry 1 are independently driven with consequent risk of skewing the gantry 1. A contact arm 20 is rigidly secured to the gantry 1 near the pivot 11 and is normally positioned midway between pairs of limit switches LS1, LS2 and LS3, LS4 attached to the leg 3, Fig. 4A. If, for example, the gantry 1 is moved in the direction of arrow F, Fig. 4B, and the leg 3 leads the leg 2 then LS2 is actuated and causes adjustment of the relative speed of the legs 2, 3 to reduce their relative displacement to zero. LS3 is a back-up switch which is actuated to cut off all power if the skew increases significantly above that which causes LS2 to be actuated. LS1 and LS4 act similarly if the leg 3 lags behind the leg 2 in the direction of gantry movement F. Fig. 5 (not shown) indicates a control circuit wherein skewing in either sense in either direction of movement of the gantry 1 is corrected.

Abstract: 1,252,636. Semi - conductor devices. WESTERN ELECTRIC CO. Inc. 20 March, 1969 [25 March, 1968], No. 14587/69. Heading H1K. In the manufacture of a (Gunn-effect) semiconductor device, two spaced apart ohmic contacts are formed to an epitaxial layer of the conductivity type grown on a substrate; these contacts are made to extend through at least substantially the depth of the layer. The substrate may later be removed. As described, a high resistivity gallium arsenide wafer has an N-type epitaxial layer grown on one of its faces. This layer is provided with a silicon oxide masking layer 14 which exposes only the desired contact areas. The masked wafer is then immersed in molten tin 19 saturated with gallium arsenide and the temperature raised to dissolve the exposed parts 16 of the epitaxial layer. The melt is then cooled to redeposit gallium arsenide, now heavily doped with tin, in these parts. The excess melt is poured off and the wafer cleaned. After provision of thin film contacts, the substrate wafer is partially lapped off. The still self-supporting assembly is then bonded, at the contacted surface, to a first beryllia block. After this, the wafer may be further reduced in thickness or completely removed, for example by etching (with I.R. thickness monitoring). A further beryllia block is then bonded to this face of the assembly. In practice many devices are produced in one wafer which is subdivided after the stage in which the first beryllia blocks are bonded to the contacted surfaces. Alternative heatdissipating supports are metal blocks thermocompression bonded to thin layers of semiinsulating substrate. Removal of semi-conductor at the contact area of the epitaxial layer and its replacement may be made separate processes.

Abstract: 1,267,097. Welding by fusion. LINDE A.G. 11 Dec., 1969 [12 Dec., 1968], No. 60447/69. Heading B3R. In flux-submerged arc welding using a consumable wire electrode the voltage drop between the electrode and workpiece is maintained at such a low value that the positive column region of the arc substantially fails to exist and the welding current is maintained at a value greater than 1000 amps. It is stated that the arc normally comprises three regions, viz. anode drop (the region adjacent the anode), cathode drop (the region adjacent the cathode), and positive column (the region between the anode and cathode drops). The voltage drop over the anode and cathode drops together is stated to be about 22 Volts in submerged arc welding and has only small dependence on current strength. Hence, the welding voltage is set in the region 22-24 Volts in dependence on current strength for currents between 1000 and 4000 amps, and as a result the positive column region is substantially eliminated. Greatly increased welding rates are stated to be obtainable in such conditions. Preferably the diameter of electrode is 6 to 8 mm. for currents in the range 1000-2500 amps, and at least 7À0 mm. for currents in excess of 2500 amps. Preferably, also, the length of the electrode between the current input and its tip is less than 35 mm., and a constant voltage/ current source is used which obviates the need to control the wire feed. A welding rate of 300 cm./min. is referred to.
