Title: Catalyst for the production of formaldehyde from methanol
IPC: B01J23/881
Filed: 1961-03-17
Abstract: A non-supported active catalyst for the catalytic oxidation of methanol to formaldehyde consists of 78-81% MoO3, 15,5-17,5% Fe2O3, 1,5-3,3% CoO, has, in the finished product, the weight ratios Mo/Fe of 4,2-4,8 and Mo/Co of 20,0-45,0 and has a high degree of crystallinity.  It may be in the form of cylinders whose height and diameter both equal 3,5 mm. and which have an average breaking load of at least 7 kg. per cylinder.  The process by which the catalyst may be made is described wherein iron molybdate is precipitated from a mixture of aqueous solutions of a molybdate and an iron salt, the precipitate is washed to eliminate soluble salts, and filtered and dried to reduce the water content to 40-50%; a cobalt salt is precipitated from aqueous solution, which precipitate is washed to eliminate soluble salts, filtered and the water content is reduced to below 70%, by drying if necessary; the two precipitates are mixed in a mil having rolls rotating at different speeds, the resulting material is shaped into granules which are subjected to a further gradual drying at temperatures increasing up to 120 DEG C.; and then activated by a progressive thermal treatment at temperatures up to 450 DEG C.ALSO:Methanol is oxidised to formaldehyde in the presence of a non-supported active catalyst comprising 78-81% MoO3, 15.5-17.5% Fe2O3, 1.5-3.3% CoO and having in the finished product the weight ratios Mo/Fe of 4.2-4.8 and Mo/Co of 20.0-45.0 and having a high degree of crystallinity.
Patent GB-812977-A (GB)
Title: Temperature-compensated transistor amplifier
IPC: H03F1/30
Filed: 1956-03-29
Abstract: 812,977. Transistor amplifying circuits. GENERAL ELECTRIC CO. March 29, 1956 [March, 30, 1955], No. 9862/56. Class 40 (6). In an amplifying stage the output for a given input is maintained constant with varying temperature by employing a negative feedback circuit including a temperature-sensitive element. The emitter resistor 16 of transistor 10 driving output transistor 20 is shunted by a resistor 17 having a negative temperature coefficient. A blocking capacitor 18 prevents variations in the D.C. working potentials while a resistor 14 determines the base bias. In order to maintain a constant power output from transistor 20 with a rise in temperature the drive applied to the emitter must be increased. The fall in effective resistance in the emitter circuit of transistor 10 reduces the negative feedback so that the effective gain of transistor 10 is increased. In a modification, Fig. 2 (not shown), a resistor having a positive temperature coefficient is connected in series with a blocking capacitor across the resistor 14. In the circuit of Fig. 1 the input resistance falls with rising temperature whereas in the modification the input resistance increases with temperature. This variation may be utilized together with the matching to a previous stage to give an overall characteristic which rises or falls with temperature.
Patent GB-970790-A (GB)
Title: Process for the preparation of primary alcohols
IPC: B01J23/90
Filed: 1962-03-15
Abstract: Primary alcohols are produced by hydrogenating a C7 to C22 aliphatic monoepoxide having a terminal epoxide group in the presence of a catalyst which contains at least 50% by weight of cobalt, iron or osmium or at least 50% by weight of a mixture thereof and optionally also containing at most 50% or preferably 35% by weight of nickel, referred to the metal in the catalyst; the hydrogenation may be effected at 100 to 250 DEG C. preferably 120 to 200 DEG C. at superatmospheric pressures up to 400 ats. There may also be present as activator a small amount of thorium, magnesium or alkali metal and the catalyst may be supported on a carrier e.g. aluminium oxide, aibieic acid or pumice. In the examples, which include the preparation of catalysts (see Division B1), the use of catalysts outside the scope of the invention is contrasted, and purification of the resulting products, which contain minor amounts of paraffins and secondary alcohols is effected by vacuum fractional distillation using a spinning band column. Batch and continuous hydrogenation over fixed beds of catalyst are described.ALSO:Catalysts containing at least 50% by weight of cobalt, iron or osmium metal or at least 50% by weight of a mixture thereof, and up to optionally 50%, preferably 35%, by weight of metals present of nickel are employed for hydrogenating aliphatic monoepoxides to primary alcohols (see Division C2).  There may also be present, as activator, a small amount of thorium, magnesium or alkali metal and the catalyst may be supported on a solid carrier, e.g. aluminium oxide, silicic acid or pumice.  In the examples there is described the detailed preparations of a cobalt catalyst containing magnesium and thorium by precipitating the carbonates on to kieselguhr, the final activation being carried out by reduction in hydrogen, and of a non supported, tabletted cobalt manganese catalyst.  The use of other catalysts prepared by identical means or literature methods, as the case may be, is referred to.

Title: Improvements in or relating to telephone transmission systems, particularly two way repeaters
IPC: H04B3/20
Filed: 1929-03-27
Abstract: 308,816. Telefonaktiebolaget L. M. Ericsson, (Assignees of Laurent, T.). March 21, 1928, [Convention date]. Two-way repeaters.-In a four-wire system speech transmission in one pair short-circuits the second pair. Speech over the pair I affects the device D (shown in full in Fig. 3) which enables direct current to flow between v1, v2, heating glow lamps G1, G2 and thus placing a balanced. short circuit for speech currents between d1, d2. Speech-frequency potentials from T3 super-added to the battery E3 cause a glow-lamp G3 to glow and thus alter the grid potential in the valve F3. The condenser C3 and resistance R3 damp out variations in the grid potential if a regular speech-frequency current (e.g. for signalling) is passed by T3 so that only the envelope of the speech curve is passed by F3 to T4, which is designed to transform these low frequencies to light G4. Condenser C4 and resistance R4 are designed to damp out these modulations as far as possible so that the grid of F4 obtains an almost constant voltage, and direct current suf6- cient to light the lamps G1, G2 passes between v1, v2. The transformers T1, T2, Fig. 1, provide a high-impedance section in the line II to render the short-circuiting of this line more effective. In Fig. 2 the short-circuit is across the secondary of a loop transformer and the charging time of the condensers C1, C2 is reduced by a choke L. The term " glow lamps " includes any device capable of independent discharge, such as a Neon lamp, but excludes thermionic devices.

Title: Driving method for optical modulating element
Inventor: TOYONO TSUTOMU
IPC: G09G3/36
Filed: 1986-01-07
Abstract: PURPOSE:To effectively prevent a display state from being inverted into another display state in the middle of a write scan of one image plane by preventing a voltage from being applied to a picture element in a fixed direction for a long period. CONSTITUTION:The whole image plane is placed in a 'white' state at a time or sequentially in a step T. The 1st phase t1 is a phase in which a weak electric field is prevented from being applied in a fixed direction continuously, and a signal having the opposite polarity from an information signal applied to a signal electrode group in the phase t1 is applied in a phase t2. When a pattern shown in a figure is displayed, a driving method which does not have the phase t1 is used and then a picture element A becomes black at a scan on a scanning electrode S1, but an electric signal applied to a signal electrode I1 has -Vo continuously after S2 and the possibility that the picture element A is inverted into white eventually is large. For the purpose, all picture elements on an image plane are placed in the 'white' state previously and temporarily and a voltage -3Vo is applied in the phase t1 for 'black' writing, but the display state is not determined in this phase t1 and a voltage 3Vo for writing 'black' is applied in the following phase t2.
