Title: Process of converting nitrous gases into concentrated nitric acid
IPC: C01B21/26
Filed: 1921-01-07
Abstract: In the preparation of concentrated nitric acid by the absorption of nitrous gases in strong sulphuric acid, the nitro-sulphonic acid thereby produced is decomposed by means of vapours of watery nitric acid.  The latter are passed into the bottom of a tower packed with acid-resisting material, down which the nitro-sulphonic acid is allowed to flow, and air may also be introduced to facilitate the evolution of nitrous gases and vapours of concentrated nitric acid. The latter, on condensation, form red fuming nitric acid, while the former are condensed in water and used for decomposing further quantities of nitrosulphonic acid.  The nitrogen oxides obtained by passing air through the fuming nitric acid to decolorize it, are similarly employed.  The concentration of the denitrated sulphuric acid is 80 per cent.  Specifications 6366/08 and 27239/13, [Class 32, Distilling &c.], are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) states also that instead of air, a gas which preferably contains oxygen may be employed, together with the vapours of dilute nitric acid, to facilitate the removal of the nitrous oxides and nitric acid.  This subject-matter does not appear in the Specification as accepted.

IPC: B65H1/06
Filed: 1963-01-09
Abstract: 988,552. Feeding sheets. R. HEPP. Jan. 9, 1963 [Jan. 18, 1962], No. 952/63. Heading B6B. In apparatus for separating folded sheets A sequentially from the bottom of a stack, the folded edges are engaged by a pair of endless belts 22 which are driven intermittently and for a period of time which is readily adjustable during the operation of the apparatus, whereby the downward movement of the sheets towards the sheet separator is controlled to suit the speed of separation. As shown, the sheet stack is supported by a series of rollers 20 and three sets of discs 13 arranged in a framework 17 which is secured to a shaft 18. The shaft 18 is rotated continuously counterclockwise, and each of the rollers 20 and discs 13 is rotated clockwise. The discs 13 are mounted on a hollow shaft 15, and are each provided with a sucker 19 which communicates through the shaft 15 with a source of vacuum, whereby the folded sheets are separated from the stack. The folded edges of the sheets bear against tongues 1 removably secured on bars 2 resting on a crossstrut 3 secured to side flanges 4, 5 which can be pivoted about an axis 7 by manually operable handles. At the rear edges, the sheets rest against a brush 10 pivoted on a curved rod 11 which is adjustably mounted in a holder 12. The belts 22 are carried by rollers 23 adjustably mounted on the adjustable bars 2, and are driven by friction discs 26 secured to a shaft 27. A cam having three operative lobes and secured to the drive shaft 18, rocks a bell-crank lever connected to a casing surrounding one end of the shaft 27, and this casing is connected to one end of a coil spring which forms a one-way clutch between the casing and the shaft. Thus, each time the cam rocks the casing, the shaft 27 is rotated, and the belts 22 are driven intermittently to feed downwardly the folded sheets. The bell-crank is adjustable relative to the cam by a screw so that the degree of rotation of the shaft 27, and the distance moved by the belts, can be regulated. The pressure between the belts 22 and the sheet stack can be adjusted by pivoting the support bars 2.

Title: Finely comminuted water-soluble material and aqueous suspensions thereof
Inventor: ENEVER JAMES ALEXANDER
IPC: C05C1/02
Filed: 1983-08-18
Abstract: Water-soluble crystalline material which has been comminuted in a saturated aqueous solution of the material in the presence of a water-soluble crystal-growth inhibitor having a hydrophobic portion and a hydrophilic portion in its molecular structure is mixed with a deflocculant which inhibits the interaction of the hydrophobic molecular portions whenever the comminuted solid is suspended in water. The viscosity of aqueous suspensions of comminuted solid is thereby stabilised.The invention is especially beneficial in the preparation of aqueous suspensions of finely comminuted ammonium nitrate for use in slurry blasting explosives.With crystal-growth inhibitors such as water-soluble polysaccharide derivatives, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes or sulphonated polymers the preferred deflocculant, which should be different from the crystalgrowth inhibitor, may include water-soluble polysaccharide derivatives, polyacrylic acid, polyvinyl pyrrolidone, sodium lignosulphonate and/or a salt of a condensate of naphthalene sulphonic acid with formaldehyde.

Patent JP-H02180423-A (JP)
Title: Delay circuit
Inventor: KUSANO TAKAO
IPC: H03K5/151
Filed: 1989-01-04
Abstract: PURPOSE:To compose the delay circuit without considering resistance and capacity on a signal line by providing a means to detect the change of the signal line, namely, to detect that the signal line including even the tip part of its wiring is under a changing state, and to having constitution to make the detected result into an inhibiting signal for other logical gate. CONSTITUTION:A driving element 101 for a clock phi1 is composed of p-channel MOSFETs 1 and 4, n-channel MOSFET 2, 3, and 5, and a buffer 6. Further, a current sense circuit is composed of the n-channel MOSFET 3 and 5, the p-channel MOSFET 4, and the buffer 6. An element 102 is a driving element for a clock phi2 having the same composition as that of the element 101. As an initial state, clock input logic is made into '1' phi1 logic is made into '1' and phi2 logic is made into '0'. At this time, no charge is on a phi2 clock line. Consequently, no current flows in the current sense circuit, and the output of the buffer 6 in the element 102 is the logic '1'. When a clock input changes from this state to the logic '0', the output of the buffer 6 becomes the logic '1' at a point where all the charges on a clock line phi1 flow into a ground potential, and the phi2 clock line is raised to a power-supply potential. Thus, the waveforms of phi1 and phi2 are never duplicated.

Title: Apparatus for treating waste resin
Inventor: TOMIZAWA MASAKI
IPC: B29B13/02
Filed: 1984-01-09
Abstract: PURPOSE:To lower the treatment cost of waste resin without using additional fuel, by providing a combustion resin passage for feeding part of waste resin that has been melted in a melting tank to a resin burner. CONSTITUTION:Waste resin such as waste agricultural resin film is charged into a melting tank 2, a furnace main body 1 is heated by a heating burner 4, and water is fed into a steam generating pipe 8 by a pump 10. The waste resin is heated by outside heating and also by steam from the steam generating pipe to be melted efficiently. Part of the melted resin is passed through a combustion resin passage 16a to a resin burner 3 where it is burnt. When the resin burner 3 becomes operated in a steady manner, the heating burner 4 is stopped and the apparatus is operated using only the heat from the resin burner 3. Thus as additional fuel is not required, the treating cost of waste gas can be substantially reduced.
