Title: Preparation of esters of thiocarbamic acids useful as herbicides growth inhibitors and insecticides
IPC: C07C333/04
Filed: 1977-09-02
Abstract: Thiocarbamic esters are prepared by reacting a carbamoyl chloride with a mercaptan in the presence of an aqueous solution of an inorganic base and a catalytically active quantity of a phase transfer catalyst. Subsequently, the organic and aqueous phases are separated and the thiocarbamic ester is isolated from the organic phase. A substantially lower concentration of the solution of the inorganic base and a smaller excess of mercaptan are required in the novel process. The reaction is effected in a significantly shorter time.

Title: Ionic discharge devices
IPC: H01J17/32
Filed: 1957-12-02
Abstract: 845,240. Discharge apparatus. SOC. D' ELECTRONIQUE ET D'AUTOMATISME. Dec. 2, 1957 [Nov. 30, 1956], No. 37507/57. Class 39(1). A relaxation oscillator comprises a gas or vapour plasma discharge tube having at least an anode and a cathode across which is established a potential difference which is low with respect to the ionization potential of the said atmosphere in a circuit including at least one series load, at least one condenser element, one plate of which is in contact with the said atmosphere and the other plate of which, not contacting the said atmosphere, is connected to the cathode of the said tube and, within the condenser element, a beta particle emitter material ensuring a permanent transfer of electrical charges from the condenser plate connected to the cathode of the tube to the other plate upon which they are stored until ionization of the said atmosphere occurs between the said charged plate and the said cathode. In the arrangement shown, the discharge tube comprises a cathode in the form of a rod or cylinder 2 coated with an electron emitting layer 3, and a cylindrical anode 4 having a gap in which is mounted a condenser having coaxial cylindrical plates 5 and 7, the inner plate 5 being connected to the cathode 2 by a lead 8 which may extend outside the tube envelope 1. A coating 6 of a radio-isotope such as thallium 204 or silicon 31 which emits beta particles is deposited on the inner surface of the cylinder 5 which is made of nickel about 25 microns thick. The condenser 5, 7 may be evacuated or may have a solid dielectric of, for example, glass, mica or an organic material. A potential difference is applied across the anode 4 and cathode 2 by a battery 9. With a filling of mercury or cadmium vapour this potential difference may be lower than 6 volts ; with hydrogen, nitrogen, argon, krypton or xenon, lower than 12 volts, and with helium or neon, lower than 24 volts. Beta particles emitted by the coating 6 pass through the cylinder 5 and the dielectric of the condenser, and charges accumulate on the plate 7 until the potential difference between this plate and the cathode 2 exceeds the ionization potential of the gas or vapour filling. A discharge then occurs between the anode 4 and cathode 2, the condenser 5, 7 discharges and a pulse is obtained at the transformer 10. Asymmetry of the pulse shape is reduced due to the deionization time of the filling, which effect may be enhanced by adding a metastable gas to the filling. Variation of the pulse repetition frequency with temperature may be prevented by connecting in parallel with the condenser 5, 7 a negative temperature coefficient condenser which may be either outside or inside the envelope 1. A control grid may be provided in the tube, and a thermionic cathode may be used. The portion of the envelope 1 opposite the gap in the anode 4 is protected by an arcuate shield 11.

Title: Ink recorders

Filed: 1975-09-12
Abstract: 1519179 Recording apparatus PERKINELMER Ltd 8 Dec 1976 [12 Sept 1975] 37511/75 Heading G1J In recording apparatus of the type comprising means for transporting a strip chart 2 lengthwise in response to an independent variable relative to a recording pen 7 movable transversely to and in contact with the chart in response to a dependent variable, and also having means for reversing the motion of the strip chart to return it to a datum position to enable repeat recordings to be made in quick succession on the same length of the chart, the chart is pressed against a platen 3 during recording by a pressure roller 1E having a plurality of longitudinal grooves extending along the entire working length of its cylindrical surface, the grooves being separated by sharp crests. The grooves minimize smudging of the slow-drying ink used during the repeat recordings, e.g. while recording the scans of a spectrophotometer, and preferably the groove density is between 50 and 60 grooves/inch. The pressure roller 1E is mounted in a frame 1 pivotally supported on trunnions 1 D1, 1 D2 and is located above a semi-circular cylindrical section 3A of the platen 3. The pen 7 is carried by a carriage 8 slidable along a bar 9. A torsion spring 10 presses the pressure roller towards the platen. During a recording sweep, a solenoid 11 is energized. Before each return sweep, the solenoid is de-energized, allowing a spring 11B to raise the armature 11B so that a stud 11D raises an arm 12A secured to the trunnion 1D2 to lift the pressure roller 1E clear of the chart 2. As it rises the roller 1E engages a lug 8A of the pen carriage 8 to lift the pen 7 clear of the chart. When the datum position is reached, the solenoid 11 is energized again to allow the pressure roller and the pen to contact the chart ready for the next recording sweep. The frame 1 has a sharp transverse edge 1C to enable a user to tear off the chart while holding down the edge 1C hard against the chart.

Abstract: 368,421. Amalgamating hydrocarbon oils and coal. TRENT, W. E., 17, Battery Place, New York, U.S.A. Dec. 15, 1930, No. 37819. [Class 50.] Coal is purified and amalgamated with hydrocarbon oils by subjecting the produced coal to agitation with oil in the presence of water which serves to separate the ash, the amalgamated bodies being then subjected to further agitation in the presence of fresh water to eliminate additional quantities of ash. Coal, powdered to pass through a sieve of 200 meshes per square inch, is fed through a conduit 1 to an amalgamator 2, to which oil and water are supplied through pipes 3, 4, the oil being in the proportion of 12 to 13 per cent by weight of the carbonaceous content of the coal. Small plastic masses of 1/32 to 1/16 inch are formed by action of paddles 5, arid these masses together with the water containing ash flow into a receiver 7, and are carried as a conveyer 9 and delivered into a hopper 11 which feeds a second amalgamator 12. Fresh water is supplied through a pipe 14, and the plastic bodies adhere, and form larger masses of “ to 1 inch diameter which may be formed into briquettes. These larger masses are carried on a screen 15 to a container 16, ash and water being discharged through a pipe 17. Specifications 151,236 and 293,454, [both in Class 50, Fuel, Manufacture of], are referred to. Reference has been directed by the Comptroller to Specification 293,454.

A system for automatically operating windows 4 and 5 on either side of the root ridge 1 of a building comprises a horizontally pivoted weather vane 21 which tilts under action of the wind to close the window opening into the wind and open the other. The windows 4 and 5 are operated through levers 6-11 by pneumatic or hydraulic actuators 12 and 13 connected by pipe lines 15-18 to control mechanism for opening or closing the windows in response to temperature or humidity. The weather vane 21 is carried by a horizontal shaft 20 mounted in a socket 19. An arm 22 on the vane contacts one of two switches 23, 24 controlling a pneumatic or hydraulic relay 25 connected by a pipe line 26 to the window control mechanism. The vane is held in one of its extreme positions by a tension spring 28 and if a wind blows with a component perpendicular to the ridge of sufficient strength to overcome the tension of the spring 28, the vane tilts to its opposite extreme position to close the window opening into the wind and open the other. A mechanical or electric actuating mechanism may be employed in place of the pneumatic or hydraulic mechanism. The building may be a hothouse, laboratory or museum.
