Patent GB-721288-A (GB)
Title: A process for the continuous treatment of granular substances with gases or liquids
IPC: B03B4/06
Filed: 1952-01-11
Abstract: 721,288. Drying or cooling granular material. RUHRCHEMIE AKT.-GES. Jan. 11, 1952 [Jan. 15, 1951], No. 900/52. Classes 34 (2) and 64 (2). [Also in Group II] In the drying or cooling of granular material 1 the material is passed downwardly over an inclined louvred surface 3 in a vessel 1, a fluid is passed upwardly through the surface at a rate sufficient to remove the lightest components with the fluid whilstthe heavier components flow downwardly and components of an intermediate size or weight accumulate in a fluidized state at or above the upper surface of the material in the vessel and are removed through lateral outlets 10 over weirs 9. The material enters through inlet 2 and heavier material is discharged over funnel-shaped grid 4 to outlet 5. The fluid, gaseous or liquid, enters through a line 6 and leaves the vessel through outlet 7. The crosssection of the outlet 5 may be controlled according to the feed rate of material or according to the depth of the layer on one of the louvred surfaces as in Specification 665,032.

Title: Platform Scales.
Inventor: EMERY ALBERT HAMILTON
IPC: G01G19/02
Filed: 1917-01-18
Abstract: 103,666. Emery, A. H. Jan. 21, 1916, [Convention date]. Weigh-bridges; bearings; links; vibration, preventing.-The platform of a weigh-bridge is restrained against horizontal movement by flexible horizontal stays rigidly attached to the platform and to the foundation, and is supported on the weighing-levers so as to avoid straining due to temperature-changes. The girders of the platform are connected at one end by a cross-plate 2, Fig. 1, to which is securely bolted a horizontal stay-plate 4, the other end of the stay-plate being bolted to the foundation 7. Besides resisting longitudinal displacement of the platform, the stay-plate is sufficiently wide to resist lateral displacement. The stay is reduced in section near each end to increase the vertical flexibility. The other end of the platform is steadied by staybars 20 having ends of reduced section. The platform is supported on the weighing-levers by a girder 10 at one end, and by plates 18 at the other end. In order to compensate for changes due to variation of temperature, the plates 18 carry at the ends hardened plates 24, Fig. 4, having cylindrical surfaces which roll on plates 25 attached respectively to the platform and to the bearing-blocks of the weighing-levers. The pivotal points of the weighing-levers may consist of knife-edges or flexible plates. Packing 27 excludes dirt from the folling surfaces.

Title: Improvements in marking or decorating articles of thermoplastic materials
IPC: B44C1/20
Filed: 1931-01-12
Abstract: 357,457. Ornamenting. CELLULOID CORPORATION, 290, Ferry Street, Newark, New Jersey, U.S.A. Jan. 12, 1931, No. 984. Convention date, Jan. 11, 1930. [Class 93.] Articles made of thermoplastic materials, such as cellulose esters or ethers, polymerized vinyl compounds, casein, or the like, are ornamented by pressing into the surface thereof by the application of heat and pressure signs, letters, numerals, or decorative devices formed of thermoplastic materials of lower plasticity. The characters and base may be formed of the same or different materials, and, in the former case, the lower plasticity is obtained by the use of a smaller amount of plastifier. The characters may be placed in position on the article before heating and pressing or may be secured in place by an adhesive. The exposed surface of the characters in the finished article may be flush with, raised above, or depressed beneath the surface of the base. After the articles are pressed, they are allowed to cool, preferably still under pressure, and can subsequently be polished or otherwise finished. When the article is formed by a pressing operation, the formation and decoration can be performed at the same time, or the characters can first be pressed into the blank.

Title: Manufacture of guaiacol
Filed: 1965-01-08
Abstract: Guaiacol is prepared by reacting at pressures below 300 p.s.i.g. a water-insoluble divalent metal salt of catechol with a methyl halide in the presence of water and a water-immiscible organic solvent for guaiacol, separating the organic phase and recovering guaiacol therefrom, the divalent metal being a metal which forms a water insoluble sulphate, e.g. Ba++, Sr++, Ca++, Pb++, the organic solvent being inert to the divalent metal salt of catechol. The reaction takes place at 75 DEG  to 150 DEG  C.  The divalent metal salt may be formed in situ from catechol, a water-soluble mineral acid salt, e.g. a chloride or a hydroxide of the divalent metal and caustic alkali, e.g. caustic soda. Preferably the reaction mixture contains at least 0.25 mole of water soluble divalent metal salt per mole of catechol and 0.7 to 2.00 moles of methyl chloride per mole of divalent metal salt of catechol.  Specified organic solvents used are aliphatic and aromatic hydrocarbons which may be halogenated, and nitro compounds and aliphatic ethers are mentioned.  Figs. 1 and 2 (not shown) indicate flow sheets for the preparation of crude and pure samples of guaiacol and the process may be batchwise or continuous.

Filed: 1988-01-06
Abstract: PURPOSE:To let the housing side be informed of communication signals on the tool holder side by arranging coaxial coils for a receiver-transmitter for the housing side and the tool holding side. CONSTITUTION:A transmitting coil 5 and a receiving coil 6 which is coaxial with the rotating shaft of the transmitter coil are provided for the housing side and the tool holder side respectively. No.1 high frequency signals f1 in high level intermittently transmitted from a transmitter 7 is sent out to the transmitting coil 5. These signals f1 are electromagnetically combined between the coils 5 and 6 so as to be sent out as the output signals of the coil 6. These output signals are transformed into direct current voltage by a capacitor C4. which situation allows a well-known transmitter 8 excited by a capacitor C6 which is set correspondingly to the number of a tool holder, to produce signals continuously in a form of No.2 high frequency signals f2. The output signals of a transmitter T1 are produced at a smoothing capacitor 5 as envelope detection outputs. Hence, the signals f2 are produced in a gate current 9 when no envelope detection output appears. Then, these signals are transmitted from the coil 6 so as to be received by the coil 5.

Title: Device for automatically controlling mold for die casting
Inventor: SUZUKI HIDEYUKI
IPC: B22D17/20
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To hold the whole body of a die in a prescribed temp. range. SOLUTION: A target quantity T1 is calculated from a temp. A1 of the point 1 (S200) and a target injection quantity T2 from a temp. A2 (S300). Successively, a target injection ratio Tr is calculated from the ratio of the target injection quantity T1 of the point 1 as the preset fixed value and the target injection quantity T2 (S400). Then, the releasing agent is injected so that the total quantity of actually injected releasing agent to each point becomes the target total quantity T1 and the ratio of the actually injected releasing agent to each point becomes the target injection ratio Tr (S500). By this way, even local die temp. at each point can be held to in the stable casting range while holding the die temp. (average temp.) in the whole body in to the stable casting range.

IPC: H01L21/8234
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To prevent a capacitor dielectric film from being damaged at cleaning time. SOLUTION: A capacitor dielectric film 35 and a polysilicon layer 36 are formed on the silicide film 32 of the lower electrode LE of a capacitor. Then after a Ti layer and a TiN layer are formed on the polysilicon layer 36 by sputtering, a TiSi2 silicide layer 38 having a high melting point is formed by causing reaction between the Ti and TiN layers and the polysilicon layer. After the TiSiO2 layer 38 is formed, cleaning is performed by applying a voltage across a silicon substrate 10 as pre-treatment, but the dielectric film 35 is not damaged by the cleaning, because the TiSi2 layer 38 protects the film 35.
