Abstract: 440,132. Hand-propelled bicycles. DINWOODIE, L. M., 13, Clouston Street, Glasgow. Oct. 3, 1934, No. 28270. [Class 136 (ii)] A bicycle is provided with a front road wheel driven from a hand-lever, and a steerable rear road wheel controlled by a steering-member mounted on the hand-lever. A hand-lever 4 is bifurcated to straddle the front wheel 2 and is pivoted near the centre of the wheel so that it can be oscillated in a longitudinal plane to drive the wheel through a cable 6, spring winding-drum 8, one-way ratchet mechanism, and sprocket-and-chain gearing 10, 11, 12. A transverse handle 13 is horizontally pivoted at the upper end of the lever 4 so that it can be rocked in a vertical plane to steer the rear wheel 3 through a pulley 19, endless cable 18, and a pulley 17 on a rear fork 16. The lever 4 is guided by a roller 21 engaging an arcuate track on a frame member 22. The frame is fitted with footrests 15 and a sliding seat 14, which runs on rails provided on longitudinal members 23 connected by transverse members 24. In a modification, a pinion mounted on the lever 4 rolls on an arcuate rack on the member 22 and drives the front wheel through sprocket-and-chain and ratchet gearing.

Title: Method of detecting a fuel element failure
IPC: G21C17/04
Filed: 1974-07-01
Abstract: 1445827 Monitoring reactors UNITED STATES ATOMIC ENERGY COMMISSION 1 July 1974 [23 July 1973] 29065/74 Heading G6C Fuel element failure in a sodium-cooled, fast breeder reactor is detected by mixing a sample of the sodium coolant with a molten mixture of non-radio-active iodides, e.g. a eutectic mixture of barium and strontium iodides, for a sufficient length of time for any radio-active iodine present in the sodium to accumulate in the molten mixture by isotopic exchange, physically separating the sodium from the molten mixture and monitoring the molten mixture for the presence of radio-active iodine. Where a cladding failure results in the sodium coolant entering a fuel element and contacting the oxide fuel therein, the resultant interaction causes swelling and weakening of the oxide structure with solid fission products including iodine compounds being leached from the fuel by the sodium and released along with fission gases into the sodium coolant system. Such a failure needs to be detected early and its progress monitored carefully for indications of fuel washout imminency. When fuel washout becomes imminent, the reactor must be shut down and the failed fuel element removed. If the reactor has not reached full equilibrium sodium activity after start-up, a single treatment may be satisfactory, but if the original sodium activity is high, it is necessary to follow up the described treatment with another treatment in which the molten mixture remianing after the radio-active sodium has been drawn off is mixed with about an equal volume of non- radio-active sodium. Residual sodium activity in the molten mixture is then in large part transferred to the non-radio-active sodium which is subsequently physically removed.

Title: Production of synchronising impulses in a television transmitter
IPC: H04N5/067
Filed: 1937-10-25
Abstract: 504,460. Television. RADIOAKT.-GES. D. S. LOEWE. Oct. 25, 1937, No. 29072. Convention date, Oct. 26, 1936. [Class 40 (iii)] Line-synchronizing impulses 6 are suppressed during, and a short time 9 before, each framing impulse 10 in order to prevent interference between the impulses at the receiver: The line and framing impulses have the same amplitude but different durations, and the interval between the line impulses is at least the period of one line. The line impulses generated by a valve 21 are suppressed when framing impulses are applied to that valve from a framing generator 22. The impulses are mixed in a valve 5 with two grids, to which the respective impulses are applied to suppress the anode current. By reducing the framing impulses by a potentiometer 18, the time of suppression 10 in the valve 5 is made less than the time of suppression 8 in the valve 21. Alternatively, the synchronizing signals are generated by a light syren, the line impulses are interrupted by cutting off the light by a shutter, and the framing impulse is derived from this modulation of the line signals by rectification, as described in Specification 471,286. The rectifier has so great an inertia that the framing signal does not begin until the line signals have faded, and the duration of the framing signal is so shortened by biassing or by division of the potential as to last for less than the period of the interruption.

Indolyltetrazoles of Formula IV are obtained by heating a nitrile of formula with at least an equimolar weight of an azide in a liquid medium for at least 12 hours, preferably at 80-140‹ C., and optionally using a Lewis acid. Indolylacetonitriles of Formula X are obtained by reacting a corresponding substituted indole with formaldehyde and dimethylamine or N- methylaniline to form a Mannich base and treating the latter with alkali metal cyanide. Alternatively the corresponding indol-3-acetic acid (or ester), e.g. ethyl-5-methoxy-2.methyl-3 - indoleacetate, is made by Fischer indole synthesis and converted to the amide, e.g. 5-methoxy- 2 -methyl- 3-indoleacetamide which is then dehydrated to the nitrile. Pharmaceutical compositions for treatment of inflammatory diseases comprise a compound of Formula I or salt thereof and an inert diluent or carrier in forms suitable for oral or parenteral administration.

IPC: F23C3/00
Filed: 1951-12-14
Abstract: 705,447. Liquid or pulverized fuel combustion apparatus. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Dec. 14, 1951 [Dec. 15, 1950], No. 29326/51. Class 51 (1) Apparatus for burning liquid or pulverized solid fuel comprises an elongated combustion chamber 1 constructed in the form of a solid of revolution, an atomizer or injector 6 for the fuel fitted centrally at one end of the chamber and surrounded by an air supply conduit 7 which leads into the chamber and is provided with means for causing rotation of the air flowing therethrough, a further air supply passage in the form of an annular slit 10 which debouches into the chamber at or near the same end but at the circumference thereof, and means for supplying to this slit air having a rotary motion in the same rotational sense as the air supplied to the atomizer or injector. The air flowing through the conduit 7 is rotated by helically placed guide vanes 8 whilst the air emerging into the chamber from the slit 10 is given its rotational whirl by being blown tangentially via conduit 12 into the annular chamber 11 which supplies the slit. The burner flame is stabilized by a small part of the air entering, through the conduit 7 being directed by an annular partition 9, surrounding the atomizer, on to the flame. The combustion products leave the apparatus at 5 whilst ignition of the fuel is effected through an opening 14 and the flame viewed through an inspection hole 15. The air resistance offered by conduits 7 and 12 is preferably such that equal quantities of air are delivered by the conduits to the chamber 1-it is undesirable that one of these quantities should be more than double the other. It is desirable for the length of the chamber 1 to have a ratio of not less than 2:1 to the diameter. The annular chamber 11 may be provided with a plurality of tangentially arranged supply conduits similar to 12.
