Title: Manufacture of alkyl isothiocyanates
IPC: C07C331/20
Filed: 1962-06-27
Abstract: A resinous polymeric material is formed during a process for the isomerization of alkyl thiocyanates to alkyl isothiocyanates (see Division C2), wherein the alkyl thiocyanate is heated under reflux in the presence of the corresponding alkyl isothiocyanate. The polymeric material is insoluble in most organic solvents but soluble in methyl thiocyanate, chloroform and dimethyl formamide, it contains a greater percentage of carbon and nitrogen and a smaller percentage of hydrogen and sulphur than the alkyl thiocyanate from which it is formed.  The infra-red spectrum is complex but is void in the region where thiocyanate and isothiocyanate groups are found.ALSO:Alkyl isothiocyanates are prepared by heating an alkyl thiocyanate under reflux in the presence of the corresponding alkyl isothiocyanate until it is itself converted into this isothiocyanate, a proportion of the alkyl isothiocyanate is continuously fractionated from the vapours and removed and further alkyl thiocyanate is added to replace the alkyl isothiocyanate removed.  During the reaction a "natural catalyst" is produced (see Division C3) together with the trimer of the alkyl thiocyanate starting material.  The reaction may be initiated by the use of known isomerization catalysts. Examples are given.  In Example 3, methyl thiocyanate and tetraethylammonium bromide are heated to give tetraethylammonium thiocyanate and methyl bromide.

Title: Gas discharge panel display systems
IPC: G09G3/28
Filed: 1974-06-05
Abstract: 1468252 Matrix displays INTERNATIONAL BUSINESS MACHINES CORP 5 June 1974 [29 June 1973] 24814/74 Heading G5C Write and erase pulses for a gas discharge panel with crossed conductor arrays insulated from the gas, each comprise a low amplitude long pulse and a high amplitude short pulse, neither sufficient to cause a discharge alone; the relative positions of the pulses being different in write and erase operations. The conductors 14 ... 17 are normally connected to buses 24, 33 to which sustain pulses are applied. In a write or erase operation selected transistors 19, 20, 28, 29 are switched to connect respective conductors to buses 25, 34 to which sustain pulses are also applied. The low amplitude pulses 66, 68 are applied between buses 24, 25; 33, 34 by circuits 41, 42 and the high amplitude pulses 65 are applied to buses 24, 25 by circuit 45. In write operations the pulse 65 occurs in the centre of pulses 66, 68 and both are added to a sustain pulse. In erase operations the horizontal sustain pulses are switched off when the vertical sustain is zero and the pulses 70, 71 are applied, their trailing edges coinciding. The sustain pulses are resumed when pulse 71 ends. Since the high amplitude pulses are applied to both horizontal buses and no high voltages are applied to the vertical buses, the selector circuit transistors 19, 20, 28, 29 can be low voltage components. The sustain pulses across the cells of the panel may comprise a high amplitude short pulse coincident with the leading edge of a low amplitude long pulse Fig. 4 (not shown); in this case the pulses on the horizontal and vertical buses are not the same.

Title: Improvements in and relating to the combustion of liquid fuel in steam generators and the like
IPC: F23D99/00
Filed: 1919-10-11
Abstract: 156,889. Scott, L. L. Oct. 11, 1919. Liquid-fuel furnaces.-Relates to steam-generators burning heavy oil and intended more especially for steam-propelled vehicles. The boiler is of the coil type and the burner 23 is arranged at its top and smaller end, the hot products of combustion escaping between the coils into the surrounding casing. The fuel is sprayed by passage under pressure through an atomizer outlet, and is at once ignited by the electric igniter 32 positioned within the burner funnel 31. Air supplied by a fan is delivered past a non-return flap 73 and baffles 38, Fig. 2, to a casing 36 surrounding the burner and having a funnel outlet 37 concentric with the burner funnel and projecting below it so that the full amount of air does not meet the fuel till after ignition. The fan, the oil pump 15 and the feed-water pump 5 are driven by an electric motor 34 which, together with the spark, is controlled by a switch 49. An oil bye-pass 20 is normally retained closed when the motor is running by a solenoid 45 in circuit with the field coils, but is adapted to be short circuited automatically should the steam temperature rise too high. The bye-pass also serves by means of a spring 42 to prevent excessive fuel pressure. An adjustably loaded ball valve in the burner head ensures that an adequate pressure is established before fuel enters the atomizer.

Sluice gates; movable weirs.-In sluice gates or weirs, particularly those intended to supply canals with water free from silt, the coefficient of discharge is increased while maintaining the crest at such a height as to exclude silt by indined guide surfaces or flaps attached to the crest of the gate or weir. In a vertically sliding double gate 1, 2, Fig. 3, of which the lower part 2 rests when lowered behind a masonry block 3, an upstream flap 10 is hinged to the top of the gate 2, the other end of the flap 10 sliding on a sill 12, and on the downstream side of the gate is mounted a flap 13, which may be fixed to the gate or hinged thereto so as to be adjustable through a small angle and maintained in position by means of guides in the gate piers or by supporting-tackle. The flap 13 is of such a length and is so controlled as not to extend to the floor of the channel when the gate is raised. The outer edge 15 of the flap 13 may be curved as at 16, or may be curved upward. In the construction shown in Fig. 5, the lower gate is eliminated, the flaps 10, 13, being hinged to a member 18 forming the crest of the weir which is raised and lowered by mechanism and abuts against the upper gate 1 to close the sluice; or the upper gate may be omitted. Alternatively the gate may be formed as a float or rigid body 25, Fig. 6, moving vertically in a recess 26 and having its upper surface sloping up to, and awav from, the crest. Openings 28, 29 are provided for flushing out the recess 26. The Specification as open to inspection ur.der Sect. 91 (3) (a) states that a single lower gate member 20, Fig. 6 (Cancelled), may be employed, hinged at 21 and having its upper surface curved so as to present an upwardly inclined upstream surface and a downwardly inclined downstream surface. The gate 20 may be housed when lowered within a recess, and in its raised position may make contact with an upper gate or with a fixed sill 23. This subjectmatter does not appear in the Specification as accepted.
