Title: Strip feeding device
IPC: B41J11/36
Filed: 1954-05-10
Abstract: 755,999. Typewriters &c. STANDARD REGISTER CO. May 10, 1954, No. 13610/54. Class 100 (4). Relates to apparatus for printing entries on dual record strips 142, 143, Figs. 4, 6, advanced differentially past a recording station at type bars 41, especially where it is desired to make journal entries in successive business forms comprised in a journal record strip 142, which is advanced by one increment on each carriage shift of the machine and to duplicate one line from each form on the other strip 143, to form a condensed summary of the data entered on the first strip. The apparatus comprises independent feeding means for feeding each of the strips 142, 143 in adjacent superposed relation past the recording station and an auxiliary platen 101, in the form of an arcuate plate mounted concentrically to the platen roll, which may be interposed between the strips 142, 143, at that position, so that entries made on the overlying strip are not recorded on the underlying one. Means are provided for withdrawing this platen 101, Figs. 1, 4, 6, 8, when the entries are desired on both strips. Shielding means, comprising a plate 112, Fig. 8, with a flanged shield portion 113, operated by movement of the platen 101 to its interposed position, prevent the operation of a pawl 64, Fig. 8, and ratchet 61 associated with the feed device of the underlying strip and withdrawal of the platen 101 disables the shielding means 112, which are re-enabled in response to actuation of the feed device for the underlying strip. The auxiliary platen 101 may be pivotally mounted on a superstructure carrying the main platen roll 39, Figs. 4, 6, 8, for swinging movement into and out of recording position and eject means comprising a lever 128 are provided for automatically moving the auxiliary platen into the recording position after a predetermined number of feeding operations of the platen roll or by hand when desired, to turn shaft 118 to withdraw platen 101 from recording position and simultaneously move platen 39 nearer to typestation 41. When the auxiliary platen 101 is withdrawn from recording position pin wheels 85 are operated to advance strip 142 quickly to bring the first line of the next succeeding form to recording position, and the shielding plate 112 is moved in a counter-clockwise direction and the pawl 64 is free to engage and turn ratchets 61 and 108 by which the strip-feeding mechanisms are operated on the next actuating movement of an actuating slide 65, Fig. 8, carried on one of a pair of bearing plates 28, Figs. 1, 4, 6, 8, of the machine. The ratchet wheel 61 and platen roll 39 are advanced thereby one increment of movement for each reciprocating movement of the carriage of the machine. Reciprocation of the paper-feeding pins is effected by rotation of the pin wheel body, on which the pins are carried, and an internal cam as described in Specification 564,301.

Patent GB-968701-A (GB)
Title: Method for the preparation of metal oxide sols with two oxide constituents
IPC: G21C3/48
Filed: 1961-04-18
Abstract: Sols of uranous oxide coated with thoria or of thoria coated with uranic oxide are prepared by heating and agitating (e.g. by boiling under reflux) a solution of salts of the respective metals in the presence of a hydrolytic agent slowly liberating ammonia under the process conditions whereby consecutive hydrolysis takes place, and thereafter removing electrolytes from the sol.  The sols may thereafter be clad with silica by mixing with a silica sol and adjusting the pH.  Suitable hydrolytic agents are urea, ammonium carbamate, potassium cyanate, hexamethylene tetramine, acetamide and formamide, which are preferably used in amount equal to or slightly in excess of the amount required for hydrolysis.  Electrolyte-removal generally involves flocculation followed by centrifuging or decantation, redispersion in deionized water and removal of remaining ions in the resultant sol, e.g. by passage through a mixed ion exchange resin bed.  For the production of uranous oxide/thoria sols, it is necessary to start with a solution of pH 0.1-0.4, to interrupt the heating after deposition of uranous oxide (about pH 2.8) and to continue heating thereafter until a pH of 3.0-5.0 is reached. For thoria/uranic oxide, the initial solution has a pH of below 2 and heating is terminated when both oxides have formed, at a pH of 4.5-5.0. The sols produced in examples have sizes ranging from 10-150 mm  to 40-400 mm . Starting materials are Th(NO3)4 and UO2(NO3)2, and ThCl4 and UCl4.  In an example of silica cladding, the final sol is stabilized with NaOH to a pH of 8.

Abstract: 1319558 Sputtering layers on semi-conductors INTERNATIONAL BUSINESS MACHINES CORP 27 March 1972 [6 May 1971] 14224/72 Heading C7F [Also in Division H1] An electrically conductive track on a semiconductor device e.g. an oxide or nitride passivated silicon wafer comprises a layer of tantalum nitrogen overlain by a layer containing gold. The tracks, which extend from apertures overlying the diffused zones of a junction transistor in an integrated circuit wafer, are formed by reactive D.C. sputtering of tantalum in an atmosphere in which the partial pressure of nitrogen is greater than 2À5 x 10<SP>-3</SP>torr. to a thickness of 1-2000A followed by sputtering of gold to a thickness of 7000A. The layer of gold may have an overlayer consisting of #-tantalum, if further layers e. g. of insulation are to be deposited, or of tantalum-nitrogen where solder connections are to be made to it. The layers are conventionally pattern-etched to form the required conductor pattern. The sputtering apparatus may have three water cooled cathodes of different materials, the substrate being mounted on a rotatable holder having cooling channels. Presputtering takes place on a movable shutter. The tantalum-nitrogen prevents the gold from diffusing and thus alloying with the silicon, and does not itself react with the gold to lower its conductivity. The silicon contact areas are coated with platinum silicide before the tantalum-nitrogen is deposited.

Abstract: 1,146,832. Selective signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 4 April, 1966 [5 April, 1965], No. 14363/65. Heading G4H. Remote reading of consumers' meters which close contacts for a given portion of a revolution of a spindle is obtained by sampling the states of the contacts at a rate which is greater than the maximum rate of rotation of the spindles. One method of sampling is shown in Fig. 2. Each of a number of pilot wires P is connected to a pair of meter contacts M1, M2, e.g. for normal and off-peak loads.. A sampling signal which is alternately positive and. negative is applied to the wires P in turn by a scanner SC, and the resulting potentials at B, C depend on the states of contacts M1, M2. Load control relays L1, L2 may be operated by applying a long positive or negative signal to the associated wire P. In Fig. 3 (not shown), the scanning signal is supplied to wires P simultaneously, but the wires P are connected to a detector in turn by scanner SC. In Figs. 4, 5 (not shown), the sampling signal is A.C. derived from the mains supply. In Fig. 6 (not shown), each pilot wire P is connected through four meter contacts to different phases of A.C. derived from a transformer at the consumer's premises. A waveform characteristic of the states of the contacts is transmitted to the central station detector. In Figs. 7, 8 (not shown), the load control relays are connected to opposite ends of a transformer secondary at the consumer's premises and are operated by applying the appropriate phase signal to the associated pilot wire from a transformer at the central station. In Fig. 9 (not shown) the arrangement is similar to Figs. 7, 8 but in addition the meter contacts are connected to the same transformer secondary as the load relays to provide a waveform characteristic of the states of the contacts.
