Abstract: 1476602 Steering wheel movement detector NISSAN MOTOR CO Ltd 26 Aug 1975 [26 Aug 1974] 35242/75 Heading G1N An arrangement for detecting relative angular movements of the steering wheel of a motor vehicle comprises a transducer 24 which in use provides an electrical signal which increases in value in one direction of rotation of the wheel and decreases in value in the other direction of rotation, a first means 26 for detecting and storing decreasing value signals and for storing the signal when it reaches a minimum value unless the immediately previous stored value was lower then said minimum in which case no change occurs and a second means 28 for detecting and storing increasing value signals and for storing the signal when it reaches a maximum value unless the immediately previous stored value was higher then said maximum in which case no change occurs. Means, e.g. a differential amplifier 30 are also provided for detecting the difference between the stored signals at any one time and means 34 for comparing the difference with a reference value to provide an output when the difference reaches the reference value. The arrangement further includes means for resetting one of the stored electrical signals at a said output occurrence to the instantaneous value of the electrical signal, the stored value in the first means being increased on resetting or the signal in the second means being an increasing signal or at a maximum value or the stored value in the second means being decreased on resetting or the signal in the first means being a decreasing signal or at a minimum value. As described the transducer 24 comprises a potentiometer. As shown in Fig. 4, the first and second means 26, 28 comprise substantially the same circuits except that the diode D 1  provided in the means 26 is reversed with respect to the diode D2 of the means 28. The storage in each means is provided by a capacitor C 1 , C 2 . Each diode D 1 , D 2  may be shorted by a switch rs, or rs2 respectively, the switches being closed for resetting the capacitors to the instantaneous voltage. The resistance network at the input of each means 26, 28 is adjustable such that the same potential is provided at both inputs of the corresponding amplifier 40, 40'. The output is used to cancel an increasing signal in an integrator 14, the latter forming part of an alarm circuit, Fig. 1 (not shown).

Title: Improvements in and relating to colour photographic films bearing sound tracks and methods for producing the same
IPC: G03C7/24
Filed: 1935-12-24
Abstract: 467,614. Photographic colour and sound films. KODAK, Ltd. (Eastman Kodak Co.) Dec. 24, 1935, No. 35655. [Class 98 (ii)] A multi-layer colour sound and picture film has the sound track composed of silver sulphide and situated on the front emulsion layer. When the film is to be processed to a negative, the sound track is copied through a filter which cuts out light to which the lower layers are sensitive. If the upper layer is blue sensitive, the copying is done through a blue filter, a yellow filter being disposed over the other layers. If the film is processed by reversal two methods are used. In one method, the upper layer is copied as above and the under layers are then fully exposed to light to which they are sensitive. Upon reversal the under layers are entirely clear and the image is left in the upper layer only. In the other method, the exposure light is such that it will correctly expose the upper layer and over-expose the under layers, e.g. orange yellow light for use with an upper blue sensitive layer. The conversion of the sound track image to silver sulphide may be effected at any stage of the processing. In the method described in Specifications 440,032 and 447,092, after development of all layer to minus red and fixing, the sound track is bleached to a silver halide or salt by an applicator roller and immersed in a solution of a soluble sulphide. Suitable bleaching baths are specified and include ferricyanides, copper chloride, iodine and chromic acid. The film may also be exposed to gaseous hydrogen sulphide, the sound track being selectively wetted by a roller and water, passed through halogen vapour, and later through a mixture of ammonia and hydrogen sulphide, the gases being contained in long vertical chambers with suction devices at their upper ends. The humidity in the gas-toning operation is controlled to prevent edge-drying. The free sulphide is finally washed from the film by a spray of water. Alternatively a liquid sulphide bath may be applied by an applicator roller and may comprise sodium sulphide, glycerine, quinone, and hydrochloric acid. Specifications 382,506, [Group XXXVIII], and 440,089 also are referred to.

Abstract: 646,566. Guiding webs. MOUNT HOPE MACHINERY CO. Dec. 5, 1946, No. 36051. Convention date, May 17, 1945. [Class 100 (i)] An apparatus for guiding a web of cloth travelling in a predetermined plane comprises a pivoted arm carrying a pair of rolls engaging opposite faces of a marginal region of the web, and means rotatably mounted opposite the edge of the marginal region of the web, said means being out of contact with the edge of the web while the web is travelling in a predetermined path but being rotated when the web laterally in a direction towards said rotatable means whereby the arm carrying the rolls is moved about its pivot thus causing the web to move laterally towards its predetermined path. Two rolls 10 and 12, Fig. 1, mounted on an arm 14 pivotally mounted on a shaft 16 guide a web W, Fig. 3, travelling downwards in a vertical plane, the roll 12 being mounted on a bracket 21 and urged into contact with the roll 10 by a spring 32 the tension of which is adjustable. A grooved wheel 62 is mounted on a shaft 42 carried in bearings 52 fixed to a base member 18 by a frame piece 44. When the edge of the web engages and rotates the wheel 62, teeth on the shaft 42 in engagement with teeth 54 on a quadrant 58 mounted on the arm 14 cause the arm 14 and rolls 10 and 12 to be rotated in a vertical plane about the shaft 16, so as to vary the inclination of the rolls 10 and 12 and consequently their guiding effect. The weight of the rolls is counterbalanced by a tension spring 78. Rods 72 and 74 are pro. vided for guiding the selvedge into the groove and maintaining it taut. A pair of rolls 10 and 12 are mounted adjacent each edge of the web and their distance apart may be adjusted to suit varying widths of web by slidable members carrying the base members 18, the slidable members being moved by a rotatable screwed bar. In a modification, the rotatable wheel 62 may be carried by the arm 14 and the quadrant may be fixed relatively to the arm 14. The apparatus may be modified to guide webs travelling upwards in a vertical plane or webs travelling in a horizontal or in any inclined plane between horizontal or vertical. If in any particular case gravity is not effective for swinging the frame in the required direction, suitable springs may be employed for this purpose.

Title: Process for purifying fluids containing carbonyl sulphide as impurity
IPC: C10K1/14
Filed: 1956-11-28
Abstract: Gaseous or liquid fluids which are at least partly immiscible with water and containing carbonyl sulphide as impurity, such as hydrocarbons and industrial gases including water gas, coke-oven gas, producer gas and illuminating gas, may be purified by contacting as a gas or liquid with aqueous diethanolamine for at least 15 seconds at not more than 70 DEG  C. and separating from the diethanolamine phase.  The fluid and aqueous diethanolamine may be mixed with a propeller mixer or centrifugal mixer, the mechanical power supplied to the mixture being from 0.2 to 1.5 kilowatts per cubic metre.  In treating gases the volume ratio of aqueous diethanolamine to the gas phase is between 5 and 20 : 1; in treating liquids the ratio of aqueous diethanolamine to the liquid is at least 1 : 10 and is preferably about 1 : 2.  The concentration of the aqueous diethanolamine is usually 10-60 weight per cent of diethanolamine. Substances such as triethylene glycol or 2-methoxy ethanol may be added to promote the passage of carbonyl sulphide to the diethanolamine solution.  The process may be applied to the purification of a propane or butane fraction from a cracking process; this will generally be carried out in the liquid phase at superatmospheric pressure.  Multi-stage operation using a countercurrent flow can be used.  The product generally will contain less than 0.0001 per cent by weight of carbonyl sulphide sulphur and 0.0005 per cent by weight of hydrogen sulphide sulphur.  In an example, pentane containing both carbonyl sulphide and hydrogen sulphide was treated using a two-stage countercurrent washing with 20 per cent aqueous ethanolamine in varying volume ratios of solvent to hydrocarbon in each stage between 0.3 : 1 and 0.5 : 1 at 20 DEG  C.; the total sulphur content which in the feed varied from 232 to 298 X 10-4 weight per cent was reduced to from less than 1 to 4 X 10-4 weight per cent.
