Abstract: 1374374 Isoxazolopyrimidines and their preparation FMC CORP 13 Oct 1972 [15 Oct 1971] 47240/72 Heading C2C  Substituted isoxazolopyrimidines of the formula wherein R and R<SP>1</SP>, which may be the same or different, are straight or branched aliphatic hydrocarbon radicals having 1 to 4 carbon atoms may be obtained by reacting, in an acid medium, a 5-alkyl-3-amino-4-cyanoisoxazole of the formula with an acylating agent containing the radical R<SP>1</SP>-CO-. The acylating agent employed may be an acid chloride or anhydride and a suitable acid is sulphuric acid. The isbxazole starting materials may be obtained by reacting malononitrile with the appropriate trialkyl orthoalkanoate to give the corresponding 2-cyano-3- alkoxy-2-alkenenitrile, hydrolysing the latter to give the 2 - cyano - 3 - hydroxy - 2 - alkenenitrile (which may also be obtained by the reaction of malononitrile with the appropriate acid anhydride in the presence of potassium carbonate), treating the free hydroxy compound with PCl 5  to give the corresponding 3-chloro-2-cyano-2- alkenenitrile, and reacting the latter with N- hydroxyurea (prepared by the reaction of hy. droxylamine hydrochloride with ethyl carbamate in the presence of sodium hydroxide). The products possess herbicidal properties and may be formulated and applied in a conventional manner.

Abstract: 1405942 Phosphorus pentasulphide HOOKER CHEMICALS & PLASTICS CORP 19 Oct 1972 [12 Nov 1971] 48198/72 Heading C1A A process for increasing the reactivity of phosphorus pentasulphide (P 4 S 10 ), as measured by its reaction with n-hexanol, comprises heating an inert gas, e.g. N 2 , CO 2 , He, Ne, A or CCl 3 F, mixing the inert gas with vapours of P 4 S 10  and condensing the vapours of P 4 S 10  to separate the P 4 S 10  of increased reactivity from the mixture. The vapour may be produced by maintaining molten P 4 S 10  at a pressure of 200- 300 mm. Hg., then the inert gas is introduced into the vapours of P 4 S 10  at a point remote from the molten P 4 S 10  but upstream of the condensation region and the P 4 S 10  vapours are condensed by contacting with a second stream of inert gas.

Abstract: 1,153,386. Electric selective signalling. A. C. COSSOR Ltd. 15 Feb., 1968 [24 April, 1967; 27 Oct., 1967], Nos. 18826/67 and 48989/67. Heading G4H. To detect whether a first pulse is followed after a predetermined interval by a second pulse the first pulse is entered into a shift register (shifted under the control of clock pulses) either one or two stages being set to their "one" state by the first pulse in accordance with its time of arrival relative to the clock pulses, gates connected to some of the register stages passing the first pulse after a predetermined delay to coincidence circuits to which is fed the second pulse. In one embodiment (Fig. 1), to determine whether a second pulse arrives 4 Ás after the first, if the first pulse arrives during the first half P of a clock pulse cycle, after 4 Ás the pulse is in stage 14 of the shift register and during the second half cycle P of the next clock pulse cycle, i.e. after 4 to 4À5 Ás delay, AND gate 23 gives an output to trigger one shot multivibrator 26 the output of which is connected to the coincidence circuits 20. If the pulse arrives during a second half P of a clock pulse cycle the "1" state of the circuit stage 10 is transferred to the next stage 11 during the first half P of the next clock pulse cycle and since the trailing edge of the input pulse occurs during this first half cycle stage 10 is again set to "1". In this case during the first half of the fifth cycle of the clock pulses stages 14, 15 are set to their "1" state and via AND gate 25 trigger the one shot multivibrator 26 as before. In the embodiment of Fig. 2 (not shown), in which the input pulses are not of precise duration the shift register stages are preceded by logic circuitry which, as in the embodiment of Fig. 1, controls the setting of either one or two stages to the "1" state in accordance with the time of arrival of the input pulses relative to the clock pulses. In the embodiment of Fig. 3, the outputs of the n - 1, n, n + 1 and n + 2 stages of the shift register are selectively coupled to AND gates 40, 41 and 42 to give an output via an OR gate 43 and one stage shift register 34 to the coincidence circuit 20. The apparatus may be used in secondary radar transponders.

Abstract: 1415297 Conveyer belts HARLEYFORD HYDROSAND EQUIPMENT CO Ltd 23 Oct 1972 [21 Oct 1971] 49040/71 Heading B8A [Also in Divisions B1 and F3-F4] Water is removed from wet solids by compression between a perforated conveyer 1 and a roller or an endless belt 15 driven in the same direction as the conveyer. Before being compressed the solids are sprayed by sprays 10 to clean and disintegrate them. The compressed solids are removed from the conveyer 1 by a scraper. The conveyer 1 may be of the type described in Specification 1,160,244 with an upper portion perforated with slits, a base portion with larger perforations and sidewalls. The belt 15 may be slightly inclined to the conveyer 1. Rollers 19, 20 acting on the belt 15 and conveyer 1, respectively effect the compression. Rollers 19 may be individually mounted from the frame 11 on sprung arms. Rollers 20 may have circumferential grooves to assist drainage. The head drum 4 (Figs. 4a, 4b, not shown) comprises a perforated outer surface on a perforated inner axle to which compressed air is supplied. Rotatably mounted on the inner axle is an intermediate coaxial cylinder, maintained stationary by a ballast weight, with a longitudinal slot which directs the air from the inner axle to those perforations in the outer drum surface that are simultaneously overlying it, clearing the slits in the conveyer 1 as they pass over the drum 4. Additionally or alternatively the conveyer may pass over a similar drum to the axle of which suction is applied. Shafts 47 (Fig. 6a) are carried above the conveyer on wheels 48 which are rotated by being supported on the conveyer outside its sidewalls 46 and transport away any large articles 50. An indicator 8 detects unduly large articles on the conveyer and stops the machine. The conveyer is cleaned on its return flight by rotary brushes and water jets and a scraper cleans the belt 15. The machine may be mounted on a wheeled chassis (Fig. 5, not shown).
