Title: Improvements in the hydration of acetylene
Filed: 1930-01-06
Abstract: A catalyst for the preparation of acetaldehyde and crotonaldehyde from acetylene and steam is prepared from cadmium oxide and phosphoric acid.  In the example, 128 parts of cadmium oxide are dissolved in an aqueous solution of 98 parts of orthophosphoric acid. The solution is evaporated to dryness, and the product dried and pelleted.ALSO:Acetaldehyde; crotonaldehyde; catalytic agents' preparation and treatment of.-Acetylene and steam' preferably in the ratio of 1 : 3, are passed at elevated temperature, e.g. 300-400 DEG C., over a chemical compound containing cadmium, phosphorus, and oxygen, with or without hydrogen.  Suitable starting materials for the preparation of the catalyst are cadmium oxide and phosphoric acid. Usually the main products are acetaldehyde and crotonaldehyde, but small amounts of acetic acid, methane, and oxides of carbon may be obtained.  The ratio of the acetaldehyde to the crotonaldehyde produced depends on the exact composition of the cadmium phosphate employed.  If the ratio of the number of molecular proportions of phosphoric anhydride (P2O5) to the number of molecular proportions of cadmium oxide in the compound is below 0,4 or above 0,6, only very small quantities of crotonaldehyde are obtained, while at a ratio of 0,47 the yield of crotonaldehyde rises to a maximum.  The total conversion of acetylene to acetaldehyde and crotonaldehyde also reaches a maximum at the same ratio of 0,47.  In the example, 128 parts of cadmium oxide are dissolved in an aqueous solution of 98 parts of orthophosphoric acid; the solution is evaporated to dryness, and the product dried and pelleted.  Over this catalyst a mixture of 3 volumes of steam and 1 volume of acetylene is passed at a temperature of 350 DEG  C. and a space velocity of 100 reciprocal hours.  The reaction gases are cooled, and the condensate distilled, yielding 2 parts of acetaldehyde to 1 of crotonaldehyde. Specifications 154,579, 320,362, and 332,635, [all in Class 2 (iii), Dyes &c.], are referred to.

Title: Improvements in or relating to repeat length measurement and control for a rapidly moving printed web
IPC: B41F13/02
Filed: 1962-01-08
Abstract: 994, 821. Photo-electric registration monitoring. BOBST-CHAMPLAIN S. A. Jan. 8, 1962 [Jan. 19, 1961], No. 692/62. Heading G1A. [Also in Divisions G3 and H3] Apparatus for repeat length measurement in web printing comprises a pair of photo-electric scanners detecting marks a whole number of repeat lengths apart to produce pulses, means producing a waveform increasing with time and means responsive to the position of said pulses with respect to said waveform to measure deviation from correct repeat length. Photo-electric scanners 56, 58, Fig. 5, detect corresponding marks of successive patterns printed on the web. A gating signal 118, Fig. 6, derived by a photo-cell 104 receiving light from a lamp 100 interrupted by a drum 96 geared to rolls 46 and 50 is combined with the scanner outputs to raise the wanted pulses to a level sufficient to trigger a thyratron in a web pulse selector 108. Drum 96 has a further aperture which co-operates with a photo-cell 102 to generate a micrometer pulse having a sloping leading edge. This signal is duplicated by cathode followers 114, 118. Pulses 120, 122 produced by the selector 108 and representing the marks sensed by the scanners are used to pick off the voltage of the micrometer signal at the instants that they occur. These voltages are fed to a difference amplifier 150 which produces outputs indicative of the instantaneous deviation of repeat length or the deviation averaged over a period, either of which may be displayed on a local meter M or a remote meter/recorder 31. The repeat length may be corrected by rotating a crank 82, Fig. 3, which rotates shafts 64 and 65 through mitre gears 72, 76 and 14, 78. These shafts carry the movable roll 48 which may carry an index cooperating with a scale to indicate the repeat length between the fixed rolls 46, 50. The output of amplifier 150 may operate an automatic control circuit having a three phase output which can be connected to a three phase motor 38 through switches 190, 192 to control the movement of the roll 48. The period for which the correction signal is applied to motor 38 is controlled by the instantaneous deviation and the sense by the average deviation.

Title: Improvements in Spark Gap Devices
Inventor: GUTHRIE ALLAN GEORGE ALEXANDER
IPC: H01T1/04
Filed: 1966-01-07
Abstract: 1,174,766. Surge diverters. E.M.P. ELECTRIC Ltd. 3 April, 1967 [7 Jan., 1966], No. 811/66. Heading H2H. A spark gap device for a surge diverter generally similar to that described in Specification 908, 240 is modified to cause the arc to contact a surface of the extinction chamber before reaching the periphery thereof. This is achieved by producing asymmetry between the chamber and the plane in which the arc moves outwardly from the electrodes under the action of the magnetic field. In one embodiment, Fig. 1 (not shown), the chamber has a trapezoidal section and the electrodes are disposed so that the plane of arc movement is mid-way between and parallel to the two parallel sides, thus causing the arc to be cooled as it runs along the other two sides of the chamber. In another embodiment, Fig. 2 (not shown), the chamber is elliptical in section and the plane of arc movement is displaced from the major axis by suitable disposition of the electrodes. The magnet blow-out effect is provided by permanent magnets in the first embodiment and by electromagnet coils in the second embodiment, the magnets and coils being mounted on each side of the chamber. The embodiment shown in Fig. 3 uses a symmetrical arrangement of chamber section and electrodes, but displaces the plane of arc movement CC by appropriate shaping of the permanent magnets 10 to produce an asymmetrical magnetic field relative to the chamber. Such asymmetry may be produced by shaped polepieces or suitably disposed electros magnet coils. The embodiment of Fig. 5 usediscs 17, 18 each of whose four quadrants are provided with shaped surfaces alternating from a flat profile 15 to a depression 16, the discs being opposed so that profiles 15 and depressions 16 are matched for each quadrant to produce the asymmetrically-shaped chamber shown. Centre portions 19 provide the space for the electrodes (not shown). Shaping and overlapping of the profiles, depressions and other portions of the discs enable channels, steps and grooves to be provided in the chamber if desired, Fig. 4 (not shown). The permanent magnets 10 are shaped to completely enclose the arc extinction chamber.

Title: Driving method for display panel
Inventor: OGUCHI KIKUO
IPC: G02F1/133
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To dissolve cross talk phenomenon caused by characteristics of liquid crystal by reversing polarity of an applied electric field to liquid crystal of pixels in one vertical scanning period and mixing pixels to which electric fields of both polarities are applied. SOLUTION: A polarity of a (i-1)th scanning signal is set to a ground potential or positive making the prescribed DC potential a border, a polarity of a (i)th scanning signal is set to negative, and a polarity of the (i+1)th scanning signal is set to positive. This is a condition in which a polarity of a scanning signal is reversed for each signal. On the other hand, in voltage waveform Vci of a picture signal electrode Ci also, a polarity of applied voltage is reversed for each scanning signal electrode when a scanning signal and a picture signal are constituted. A voltage waveform applied to a selected pixel is made a waveform shown with VRI-Vci , and low frequency components are eliminated.  This is due to that a driving frequency of a picture having a low frequency component near a frame frequency with which cross talk is caused frequently is frequency-converted to a high frequency side, cross talk phenomenon is improved by this effect.
