Title: Improvements in and relating to paper bags and closures therefor
IPC: B65D30/24
Filed: 1926-12-22
Abstract: 287,251. Coleberd & Co., Ltd., (Bates Valve Bag Co.). Dec. 22, 1926. Securing bags, special means for.-In a paper bag or sack having an end closed by a sewed seam filter means such as a cord is provided along the seam and the thread passed through it to prevent escape of dust from the contents of the bag through the needle holes in the bag. A tubular valve bag 10, the walls of which comprise several relatively-movable sheets of parper, is closed at one end by a U-shaped binding strip 12 secured by stitching 11, the stitching being effected through a flexible cord 13 disposed outside the bag on the side at which the needle enters the material of the bag, the opposite side either having a similar cord or having its needle apertures closed by the loops in the thread formed by the stitching operation. The binding strip 12 prevents dust from escaping between the end walls of the bag and, to minimize the risk of its being damaged, it may be .adhesively secured at its lower edges to the bag. In a modification, a length of tape replaces the flexible cord.

Title: Fast Access-Content Organized Readout Memory
IPC: G06F17/30
Filed: 1968-07-08
Abstract: 1,198,008. Content organized memory systems. BURROUGHS CORP. 8 July, 1968 [31 July, 1967], No. 32551/68. Heading G4C. In a memory system comprising a memory in which words of information are stored in numerical order, means are provided for accessing individual bits in addition to complete words whereby the memory may be addresed by its contents. As shown, a core or thin film memory matrix 1-10 is provided with a memory address register MAR 1-14 for addressing word locations corresponding to rows of the matrix and a bit sequencer 1-22 for addressing bit locations corresponding to columns of the matrix. Information read (destructively) from the memory is passed to memory information register MIR 1-26 the individual bit outputs of which are OR-ed by gate 1-28 connected to two 1-bit comparators 1-30 and 1-32, the latter of which controls the rewriting of information into the memory matrix only when binary 1's are read. In operation, a word to be searched for is placed in a reference shift register 1-34 and MAR 1-14 and bit sequencer 1-22 set to values corresponding to the first bit of the first word of the numerically ordered part of the memory. This bit is read and compared in comparator 1-30 with the corresponding bit of the reference word. Depending on the result of this the bit sequencer 1-22 is incremented (compared bits equal) or the MAR is incremented (reference word bit greater than MIR bit) or the search is terminated (reference word bit less than MIR bit). This process of reading a single bit, comparing and incrementing the MAR or bit sequencer continues until an adverse comparison is detected or the MAR reaches the last word in the numerically ordered part of memory or the bit sequencer is incremented beyond the last word bit value. In the latter event the whole word corresponding to the contents of MAR are then read into MIR and compared with the reference word using comparator 1-36 to establish whether the word searched for is present or not. The disclosure includes a number of marked examples and algorithms for sorting a list of words into order, merging new words into an existing list and deleting words from a list and closing the resulting gaps.

Abstract: 929,668. Powder metallurgy. GENERAL ELECTRIC CO. Ltd. Sept. 25, 1961 [Sept. 28, 1960], No. 33305/60. Class 82. [Also in Groups XI and XL (a)] An electrode for use in electric discharge apparatus, e.g. thermionic valves, discharge lamps, and inert gas shielded tungsten arc welding apparatus, comprises an electron emissive part 8, Fig. 2, which is formed from a composite sintered body composed mainly of tungsten and consisting of a case composed of tungsten containing a dispersion of electronemissive material of low work function and, partially or wholly surrounding the core and integral therewith, an outer layer 9 composed wholly or mainly of tungsten and substantially free from such electron emissive material. The outer layer may be composed of pure tungsten with one or more additative materials, e.g. alumina, potassium silicate, for influencing the crystal structure, and the electron emissive material included in the core may comprise one or more of the oxides of thorium, zirconium, yttrium, lanthanim and the rare earth metals in a proportion in the range 10-15% by weight of the total weight of the core. The ratio of the thickness of the outer layer to the diameter of the core is preferably in the range of 7: 1 to 1:7. When the electrode is used in arc welding or spark cutting apparatus, and when used in discharge tubes one end of the electrode may be exposed, thus forming a small electron emissive portion, or the outer layer may be ground away. In a specific example of a method of manufacturing the electrode, a double funnel of the type shown in Fig. 1 is used. Silicated tungsten powder is inserted into the bottom of the mould to a level a and the inner funnel 2 inserted. The inner portion 4 is filled with thoriated tungsten to the level b, silicated tungstan fed into the portion 5 to a level slightly higher than b, and the funnel 2 carefully removed. The composite mass so formed is subjected to a pressure of approximately 15 tons/sq. inch, and the compressed powder removed. Sintering is accomplished at a temperature of 2950‹ C. in an atmosphere of hydrogen by passage of an electric current through the bar, the temperature being kept at this level for 12 minutes. The final bar may be machined and rolled or pulled into a wire for use as a thermionic cathode. Specification 898,847 is referred to.
