Patent ES-239752-A1 (ES)
Title: Processes for the control of iron bacteria and compositions for use therein
Inventor: BUCKMAN STANLEY J
IPC: D21C9/00
Filed: 1958-01-23
Abstract: The growth of slime-forming iron bacteria, e.g. Sphaerotilus natans in industrial water is controlled by the use of one or more water-soluble salts of N-monoalkyl-substituted dithiocarbamic acids the alkyl radical(s) of which contain less than 4 carbon atoms. The salts may be used in conjunction with one or more other toxicants having a greater effectiveness against slime-forming micro-organisms other than iron bacteria e.g. one or more water-soluble salts of cyanodithio imidocarbonic acid (for controlling species of Aerobacter and Pseudomonas) ortho-phenyl phenol 2, 4, 6-trichlorophenol and other polychlorophenols. The two kinds of toxicants may be added to the water together in concentrated aqueous solution, or they may be added separately, preferably first controlling iron bacteria by addition of N-monoalkyl-substituted dithiocarbamates and subsequently adding the cyanodithioimidocarbonates or other toxicants. Where other toxicants are employed which do not form concentrated aqueous solutions with N-monoalkyl-substituted dithiocarbamates, e.g. organomercury and organotin compounds and inorganic or organic compounds of copper, the toxicants are added individually in solution or as solids, or in combination as solids or suspenisons in water or other liquid. A preferred composition is an aqueous solution of a mixture of potassium N-methylditriocarbamate, sodium cyanodithioimidocarbonate and ethylenediamine in percentage proportions by weight of 18,0, 13,1 and 4,9. The alkyl-substituted dithiocarbamates are added as 0,1 to 20 parts per million of water. Specification 809,351 is referred to.

Title: Thermistor device and method of producing said device
IPC: H01L29/45
Filed: 1967-04-06
Abstract: A thermistor has two leads ohmically bonded to a doped synthetic single crystal diamond and displays a negative temperature coefficient of resistance of greater than 0.05 over a temperature range in excess of 500 C. The dopant may be boron, aluminium, or beryllium and may be incorporated (in the proportion of 0.001-1.0% by weight of diamond) during the nickel-iron catalysed conversion at 1100- 1700 C. and a pressure of 45-60 kilobars of graphite to diamond. 250-300Á diamonds are separated from residual graphite, catalyst, and pyrophyllite container material by respective treatments with sulphuric-nitric acid, hydrochloric-nitric acid, and dilute hydrofluoric acid. To make the thermistor of Fig. 1 (not shown), a degreased diamond (1) is placed in contact with degreased heat sink-lead assemblies consisting of iron-nickel-cobalt leads (4) welded to molybdenum or tungsten bodies (3) each coated with, for example, a palladium-nickel-chromium alloy (2). These parts were jigged with an alumino-silicate glass preform (5) in a gas-tight furnace containing oxygen-free forming gas of low dew point and heated to form ohmic con tacts and seal the assembly, the leads being pushed inwards during the process. An outer envelope (7) of devitrified glass is applied to protect the lead-heat sink welds. Oxide on the exposed portion of the leads is removed and the leads chromium-plated. Bonding alloys to replace the ternary alloy used are gold-nickelchromium, iron-nickel-cobalt, and palladiumnickel. The lead materials are tungsten, molybdenum, and the following materials which require no protective chromium coat:-platinum, palladium, and platinum-clad molybdenum. If leads are attached directly to the diamond, alloying, diffusion bonding, thermocompression bonding, ultrasonic welding, or nail-head bonding may be used. If headers are used bonding materials may be placed thereon by evaporation, as a slurry, or by firing-on an alloy preform. The atmosphere used in the firing stage and which is retained within the encapsulation, may instead be argon, helium, nitrogen or hydrogen, or the firing may be effected in vacuo.

Filed: 1968-12-28
Abstract: A slave press B is maintained in synchronism with a master press A. The press B is driven by a motor 21B through a variable coupling 23B whose energization is controlled by a circuit 31B the input to which is the algebraic sum of the signals from a speed reference source 39, from a tachometer 29B whose output varies in amplitude with the speed of the press and from a phase comparator 51B whose output varies in amplitude with the angular displacement between the crank-shaft of the press and the reference standard A. As shown the reference press A is also driven through a coupling 23A controlled to maintain the speed set by the speed reference 39 and drives the rotor 43A of a selsyn 41A. The press B also drives a selsyn 41B, the stators of the two selsyns being coupled. The A.C. supply to selsyn 41A is compared with the output of 41B by a phase discriminator 51B whose output is fed to the control circuit 31B. The speed reference 39 may provide a fixed reference or may vary so that the presses follow a set programme. In a modification, Fig.2 (not shown) the selsyns are replaced by pulse generators feeding digital counters whose outputs are compared and the result converted in a digital to analogue converter to a phase error signal which is fed to the control circuit 31B as described in Specification 1,223, 202.
