Title: Improvements in or relating to the preparation of reduction products of n-phenyl-3, 5-diethyl-2-propyldihydropyridine
Filed: 1948-01-19
Abstract: N - phenyl - 3,5 - diethyl - 2 - propyldihydropyridine is hydrogenated at elevated temperatures, preferably 20 DEG  to 150 DEG C., and pressures, preferably 3 to 100 atmospheres of hydrogen, and preferably in the presence of a hydrogenation catalyst such as Raney nickel, and metallic platinum and palladium.  One, two or five mols. of hydrogen may be added by successively increasing the temperature, pressure and quantity of hydrogen used.  In examples the dihydropyridine is hydrogenated in the presence of a Raney nickel catalyst and (1) and (2) ethanol at (1) 3 atmospheres, (2) 70 atmospheres and (3) 100 atmospheres of hydrogen with corresponding temperatures of room temperature, 100 DEG  C. and 150 DEG  C. and times of 3 hours, 10 hours and 20 hours and the following products isolated by fractionating at reduced pressure: (1) N-phenyl-3,5-diethyl-2-propyltetrahydropyridine; (2) N-phenyl-3,5-diethyl-2-propylpiperidine; and (3) N-cyclohexyl-3,5-diethyl-2-propylpiperidine.  The dihydropyridine used as starting material is prepared by gradually adding aniline to commercial butyraldehyde dissolved in dilute acetic acid p  solution at about 10 DEG  C., refluxing for 5 hours, cooling, removing butyraldehyde and 2-ethylhexenal from the oil layer by steam distillation which is then dried and extracted in the cold with dilute hydrochloric acid and benzene to leave an oil layer from which the required product may be obtained by reduced pressure fractionation.  N-Butylaniline and the reaction product of 2 mols. of butyraldehyde with 1 of aniline are obtained amongst the by-products.ALSO:N - phenyl - 3,5 - diethyl - 2 propyl - tetrahydropyridine, N-phenyl-3,5-diethyl-2-propylpiperidine and N-cyclohexyl-3,5-diethyl-2-propyl-piperidine are active insecticides, fungicides, bactericides and herbicides. Compositions containing 1 per cent of the above compounds are effective against cotton beetles and in fly sprays and when containing 10 p.p.m. are effective against mosquito larva.  A kerosene composition containing about 5 per cent by weight of the compounds is effective in weed-killing.

Title: Improvements in or relating to computer priority circuits
IPC: G06F9/48
Filed: 1966-01-13
Abstract: 1,135,554. Multi-programme priority arrangemerit. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 Jan., 1966 [16 Jan., 1965], No. 1655/66. Heading G4A. A priority control arrangement is described for storing randomly occurring requests for the execution of different programmes arranged in groups and for controlling their execution according to a system of priorities. Thus a request for a programme in a higher priority group may interrupt a programme in a lower priority group (strong priority) and a request for a programme in a group in which a programme is already being executed may take precedence over lower priority programmes in the same group only after the current programme is completed (weak priority) or the programmes within a group may have no priority over one another but may merely be taken in cyclical order. As shown schematically in Fig. 3, the arrangement comprises a plurality of request registers A, B, C and D (shown in detail in Fig. 4) a group register Gr (described in detail with reference to Figs. 6-8, not shown) and an address generator Adr. Gen. Each of the request registers A-D has inputs (B 1 -B 4 ) for receiving request signals for the respective programmes and comprises flip-flops (FF 1 - FF 4 ) for storing these requests, a cyclically operating counter TS for scanning the flip-flops in turn to establish which is set and a status flip-flop for indicating (when set) that a programme in that group has been started. The group register Gr, by means of signals from those flip-flops in registers A-D which have been set and by means of signals a and b from the computer which indicate respectively the ending of an instruction and the ending of a programme, performs a book-keeping operation and issues programme start and cancel signals to the registers A-D and programme interrupt signals to the address generator. The address generator, on receiving an interrupt signal, stores the address of the next instruction in the current programme (one store per group being provided) and then passes control through group register Gr to the register A-C corresponding to the request for a programme of higher priority. The invention is said to have applications in signal (e.g. telegram) handling centres.

Title: Improvements in electron discharge devices of the velocity modulation type employingresonating chambers
IPC: H01J25/12
Filed: 1942-02-10
Abstract: 582,491. Yelocity-modulated tubes. BRITISH THOMSON-HOUSTON CO., Ltd., and MILNER, C. J. Feb. 10, 1942, No. 1775. [Class 39 (i)] To avoid delay in the building up of oscillations when voltage is applied to the electrodes of a velocity-modulated discharge tube employing resonator chambers, the voltage impulse resulting from the initial application of operating voltage is communicated to the interior of the resonating chamber or chambers to shock the chamber into oscillation. A probe may extend into the chamber or be coupled to an electrode extending into the chamber. In one form, a loop 8 is connected to the resonator chamber 2 and capacity coupled at 7 with the electron gun 1. In another form, the outer conductor 5 of the output loop 6 is insulated at C1 from an extension 12 earthed directly or through a spark-gap 15 ; the collecting electrode 4 is earthed. When the electron gun receives its biassing potential, a surge passes through the loop and shocks the resonator chamber 3. Specification 582,484 is referred to.

Title: Improvements in or relating to radio apparatus for detecting and locating objects
IPC: G01S1/02
Filed: 1943-02-03
Abstract: 610,704. Radiolocation. SPERRY GYROSCOPE CO., Inc. Feb. 3, 1943, No. 1835. Convention date, Aug. 12, 1941. [Class 40 (vii)] In a radiolocation system of the pulserepetition type comprising a single scanning antenna system for emitting energy and receiving the reflected energy, indicator means show the azimuthal and elevational positions of a reflecting target and also its slant range. The system shown in Figs. 1A, 1B indicates only azimuthal bearing and slant range and does not itself illustrate the invention. The system shown in Fig. 5 shows how the system of Figs. 1A, 1B is modified in order to show also elevation, in accordance with the invention. First system, Figs. 1A, 1B. The pulse generator 1 causes the transmitter to produce short pulses of energy which are radiated by the antenna 7 and, after reflection, are received by the same antenna and passed via a tuned resonator 16, amplifier 20, mixer 28, I.F. amplifier 30, detector 31, videa-amplifier 32 to the control grid 41 of a cathode-ray tube. To prevent the emitted energy from affecting the receiver, the resonator 16 has a spark-gap 17 which discharges during emission and thus short-circuits the receiver. In addition, pulses from the generator 1 block the amplifier 20, prevent the generation of oscillations by the local oscillator 25, and block the video amplifier 32. The transverse deflecting coils 13 of the cathode-ray tube are connected to a potentiometer 11, the arm of which oscillates with the reflector 8. The vertical deflecting coils 34 are connected over leads 39 to a time-base circuit controlled by the pulse-generator 1. The cathode beam is normally cut off by a potential applied over resistance 36 to electrode 38, but is restored by the received pulse applied to grid 41, the position of the spot 42, Fig. 2, on the screen indicating the bearing in azimuth and the range. The cathode beam is cut off during the return stroke by a pulse applied over circuit 37 to electrode 38. Complete circuits for the pulse generator 1 are illustrated in Figs. 3A, 3B (not shown). Modified system, Fig. 5. Two cathode-ray tubes 115, 116 are used, tube 115 indicating bearing and 116 range. The reflector 8 is rotatable about horizontal and vertical pivots, and the two deflecting coils 114, 121 of tube 115 are controlled by potentiometers 111, 11 associated with these two movements. The transverse deflecting coils 117 of tube 116 are connected over circuit 39 to a time-base circuit controlled by the pulse-generator. The circuit 40 from the receiver is connected to the control grid of tube 115 and the vertical deflecting coils 118 of tube 116, the screens of these tubes indicating the bearing and range as shown in' Fig. 6. A phase comparator 123 may be connected to leads 39, 40 to give a range reading on meter 124. The scanning arrangements may be as described in Specification 610,711. Specifications 501,996, 523,712, 576,154 and 609,298, [Group XXXVI], also are referred to.

A method of forming an "iron-on" interlining having a discontinuous coating of discrete particles of thermoplastic material comprises distributing the thermoplastic material in particulate form over the surface of a carrier band, to which it does not adhere, as a single layer, and heating the particulate material on the band, the density or distribution and temperature of heating being such that the thermoplastic material remains in particulate form, and transferring the heated particulate material to a fabric by causing the fabric while travelling to bear against the exposed surfaces of the particulate thermoplastic material with a pressure such that the coating obtained on the fabric consists of discrete particles. The thermoplastic material may be polythene, polyvinyl chloride, polyvinyl acetate, or copolymers of polyvinyl chloride and polyvinyl acetate, and may additionally contain a plasticiser. The fabric may be woven, knitted, or non-woven e.g. crimped nylon fibres bonded by an acrylic polymer. The carrier band may be an endless belt coated with silicone rubber or polytetrafluoroethylene, or it may be a length of silicone rubber or of paper coated with polytetrafluoroethylene which can be repeatedly rolled into and unrolled from a coil. The band may be formed with numerous uniformly spaced depressions. The method may be carried out, as shown, by distributing thermoplastic particles from distributor 3 on to band 1, which carries the particles beneath heaters 4 to a nip between rollers 5 and 6, where the particles are transferred to fabric being unwound from coil 7 on to coil 9, the fabric being preheated by heater 8.

Title: Improvements in or relating to the removal of benzene and its homologues from an absorbent liquid
IPC: C10K1/18
Filed: 1958-01-24
Abstract: A process for removing light oil from benzolized wash oil with stripping steam while purifying the wash oil for re-use as debenzolized wash oil comprises first contacting a portion of said wash oil with steam to produce a mixture of steam and oil vapours and to leave as a residue any non-volatile components of the wash oil, <PICT:0828391/III/1> contacting the mixture with the benzolized wash oil, and applying additional heat to the wash oil and residue to said portion whereby a greater amount of said portion is converted to oil vapour than is possible by the use of steam alone.  In a preferred embodiment benzolized wash oil is passed through a conventional countercurrent oil-to-oil heat exchanger where it is warmed, and then passed on to a steam or fired heater 12 where the temperature is raised to 160 DEG  to 200 DEG  C.  The hot benzolized oil is introduced into a conventional bubble-cap tray type stripping tower 13 where it is subjected to a countercurrent upward flow of steam which removes the light oil as vapours from the wash oil, the vapours and steam then passing to a rectifying column 17 wherein the light oil is separated into two fractions, one comprising benzol, toluol and xylol and boiling below 145 DEG  C. and a heavy naphthalene fraction boiling above 150 DEG  C.  Rectification is brought about by the provision of a reflux condenser 19 and a fluid separator 20 in which the water is separated from the benzol fraction which is separated into two portions, one being used for product and another being returned to the rectifier as reflux.  A purifier 31 into which steam is introduced through a conduit 35 removes the polymerized and non-volatile impurities from the wash oil. Superheated steam is produced in heater 50.
