A rotary conical plug cock comprises a plug 13 having a passage 14 and rotatable between open and closed positions, the plug being displaceable in an axial direction and provided with a corrugated flexible tube 31 for sealing the stem 15. In order to press the plug into contact with its seat the upper end of the latter is formed with a cam surface which co-operates with a complementary cam surface 27 formed on a cover plate 28 clamped in the valve housing 11 by a screwed bonnet member 16. The lower end of the plug is also formed with helical cam surfaces 23, 24 which co-operate with complementary cam surfaces 21, 22 formed on the housing so that upon rotation of the plug to the open position the plug is lifted out of contact with its seat. To ensure satisfactory sealing, the conical surface of the plug is covered with a rubber sleeve 17 which is integrally formed with a corrugated bellows portion 31, the latter portion being clamped, via a flange 32, to the valve housing; the rubber covering on the plug may be replaced by a coating of rubber in the bore. The bellows portion is shaped with the corrugated portion 44, Fig. 10, tapering inwards towards the valve stem 15 in order to permit the axial movement of the plug. In a modification, the corrugated portion may taper inwardly from the middle towards both ends. A stop 30 on the upper end of the plug co-operates with a recess in the plate 28 in order to limit the rotation of the plug.

Patent GB-969793-A (GB)
Title: Production of adipic acid and nitrocylcohexane
IPC: C07C51/31
Filed: 1961-12-01
Abstract: Adipic acid and nitrocyclohexane are produced by reacting cyclohexane with nitrogen dioxide at a temperature between 30 DEG  and 70 DEG C. in the presence of a catalyst based on silica gel and/or a salt of vanadic acid.  The nitric oxide formed during the reaction is preferably eliminated by the introduction of oxygen. Cyclohexyl nitrate, d -cyano-valeric acid and caproic acid e -nitrate are formed as by-products and may be further converted to adipic acid by recycling or by separating them from the reaction mixture followed by oxidation of the cyclohexyl nitrate with nitric acid and hydrolysis with a mineral acid of the caproic acid e -nitrate and the d -cyano-valeric acid.  The nitrocyclohexane may also be transformed into adipic acid by treatment with sodium hydroxide to give the sodium salt of nitrocyclohexane which is converted to cyclohexanone by treatment with hydrochloric acid, the cyclohexanone being subsequently oxidized to adipic acid by means of nitric acid or nitrogen dioxide.  Examples are given.  Other by-products obtained are succinic and glutaric acids and dinitrocyclohexanes.

Abstract: 1,113,016. Battery charging systems. MARCONI CO. Ltd. 3 Aug., 1965 [22 Oct., 1964], No. 43206/64. Heading H2H. [Also in Division G3] A battery 14 floating across a supply is charged at constant current by thyristors 6, 7 which are controlled by the difference between the voltage across a resistor 13, and a reference voltage across Zener diodes 20. The resultant controls a transistor chopper 27, 28 the output from which is amplified by transistors 30, 31 and clamped with the chopper by transistor 32. The output is then passed to an integrator B, the output at point 36 being constant when the charging current is constant. When an exponential ramp voltage from circuit C exceeds the point 36 voltage a transistor 37 and hence transistors 44 conduct, firing thyristors 6, 7. A manual switch 23 causes a higher current to charge the battery should this become discharged due to say mains failure.

Title: Centrifugal fans and pumps
IPC: F04D15/00
Filed: 1975-10-06
Abstract: 1502781 Centrifugal fans and pumps INDUSTRY SECRETARY OF STATE FOR 6 Oct 1975 [4 Oct 1974] 43213/74 Heading F1C The flow-path through a centrifugal fan or pump impeller is controlled by an axially movable control plate 24. At low flow-rates the control plate 24 is moved to the position in which it aligns with the radially inner end of an annular baffle plate 8 whereby flow is confined to the region 9 of the impeller blading 2 and the flow velocity is consequently high enough to avoid stalling or cavitation. To save weight, the baffle plate 8 need not extend fully to the outer periphery of the impeller. There may be several baffle plates, the control plate 24 being alignable with each baffle plate in turn to direct the flow through a corresponding proportion of the impeller width. The impeller may comprise, in effect, two or more contiguous impellers differing in radial dimensions. Two impellers, each having its own control plate, may be arranged back-toback to constitute a double-entry impeller unit.

Title: Electrical apparatus
IPC: G01R13/04
Filed: 1971-09-17
Abstract: 1319189 Analogue to digital conversion INTERNATIONAL BUSINESS MACHINES CORP 17 Sept 1971 [10 Nov 1970] 43347/71 Heading G4H A tester for monitoring an electric circuit 10, e.g. a computer, has threshold units 12-15, the logic 1 or 0 output of a selected unit or units being gated by circuit 20 at successive points in time to successive stages of the upper and/or lower storage buffers 22, 24, the contents of each buffer being displayed on a respective visual digital display 42, 44. The tester is primarily for detecting intermittent faults in circuit 10 manifested by an aberration in a repetitive signal or the occurrence of a signal from an otherwise dead source, e.g. a fluctuation in a D.C. signal. A previous normal signal is held in the upper buffer 22 and compared with fresh samples of the signal introduced into the lower buffer 24, a non-comparison of any of the stages causing a comparator 50 to generate an error signal which is visually indicated to an operator and fed back to the circuit 10 for control purposes. Alternatively the upper and lower buffers may simultaneously each receive a signal from a different threshold unit 12-15, purely for display without any comparison. Also the two buffers may hold the real and compliment forms of a single threshold unit. Data may also be inserted manually by the operator into the upper buffer for comparison with samples introduced into the lower buffer. Stages of the upper and lower buffers are enabled successively to accept the output of a selected threshold unit by means of an oscillator driven ring circuit 26. According to operator instructions the ring circuit may automatically cycle repeatedly thereby repeatedly introducing fresh samples of a threshold unit output into the buffer or buffers and so updating the display or displays, or may commence a cycle upon an operator instruction or an external trigger or a trigger derived from the test signal itself via the same or a different threshold unit, with or without a delay. Either a positive or negative going slope of the triggering signal may be chosen to start a cycle. The oscillator frequency and hence cycling frequency is operator adjustable. Alternatively an external oscillator may be used to drive the ring circuit. The comparator error signal may be used to inhibit further cycling after the cycle from which it arose. The display, shown in cross-section, Fig. 25a, comprises an upper row of light-emitting phosphor elements represented by element 1150 and a lower row represented by element 1151. Each element is energized by a signal on line 801 or 901 of its respective SCR, which receive an A.C. energizing signal from source 1141. The whole display may be blanked by energizing SCR 1149 to short circuit the A.C. source.

Filed: 1963-11-07
Abstract: A coating or impregnating composition having a total solids content of at least 8% by weight comprises an aqueous medium having dispersed therein a water-insoluble addition polymer of monoethylenically unsaturated molecules, and a wax, said polymer containing at least 1% by weight of units from monomer molecules containing basic nitrogen atoms, the proportions of polymer and wax being 10 to 95 parts by weight of polymer to 90 to 5 parts by weight of wax; the aqueous medium also containing a dispersing agent and polyvalent metal ions other than, or in addition to, calcium or magnesium ions. Long lists of suitable monomers are given.  In the two examples ethyl acrylate, methyl methacrylate and dimethylaminoethyl methacrylate are copolymerized in aqueous emulsion using, as emulsifying agent, octyl phenol modified with 40 ethylene oxide units.  In one example, zinc chloride and butoxyethoxyethanol are added to the polymer emulsion to produce a coating composition which is sprayed on to uncured asbestos-cement shingles which are then dried and cured.  In the other example, the polymer emulsion is blended with a mixture of polyethylene wax, oleic acid and morpholine, with an ammonia soluble alkyd resin, and with plasticizers and surface active agents to form a floor polish to which is added barium acetate, nickel chloride, manganese sulphate, or zinc tetra-anmine benzoate and these four polishes are applied to rubber floor tiles.  Many other coatable rigid surfaces are specified.  Conventional plasticizers, emulsifying agents, dyes, pigments and fillers may be incorporated in the compositions.ALSO:A coating or impregnating composition having a total solids content of at least 8% by weight comprises an aqueous emulsion containing a water-insoluble addition polymer of monoethylenically unsaturated molecules, and a wax, said polymer containing at least 1% by weight of units from monomer molecules containing basic nitrogen atoms, the proportions of polymer and wax being 10 to 95 parts by weight of polymer to 90 to 5 parts by weight of wax; the aqueous medium also containing a dispersing agent and polyvalent metal ions other than, or in addition to, calcium or magnesium ions.

Patent GB-1069290-A (GB)
Title: Process for preparing organic compounds containing one or more nitrile groups
IPC: C07D309/38
Filed: 1964-11-02
Abstract: Organic compounds containing one or more nitrile groups are made by reacting a compound containing one or more carbonamide-N-sulphonic halide groups, -CO.NH.SO2X, where X is halogen, with a compound containing one or more carboxylic amide groups.  As the reaction proceeds with elimination of the halosulphonic acid which is bound by the amide, it is preferred to use at least one equivalent of amide per -CO.NH.SO2X group.  The reaction can be effected at temperatures in the range - 30 DEG  C. to 120 DEG  C. optionally in the presence of solvents or excess of the amide compound.  The amides can be recovered by treatment with water and neutralizing the separated acid.  The carboxylic amide compounds include cyclic amides, polyamides, ureas and carbamic acids.  The radical to which the -CO.NH.SO2X group is attached can be saturated or unsaturated aliphatic, cycloaliphate, e.g. cyclohexyl, aromatic, e.g. phenyl, pyrenyl, anthracenyl, or heterocyclic e.g. thiophene, pyran or pyrrole, and may be substituted by further groups, e.g. carboxylic, ketonic or alkoxy groups; the preparation of all of these types is illustrated by the examples.  The carbonamide-N-sulphonic chlorides can be made by treating compounds containing replaceable hydrogen with chlorosulphonyl isocyanate or by reaction of the latter with carboxylic acids.

Title: Displaying isodensity lines
IPC: H04N5/33
Filed: 1968-09-24
Abstract: 1,224,670. Displaying isodensity lines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 Sept., 1968 [26 Sept., 1967], No. 45357/68. Heading H4F. The Specification relates broadly to the production of isodensity lines on a C.R.T. display of the energy distribution across a scanned field, said energy being X-ray or radioactive for example. In the particular embodiment however, the energy is infra-red and the lines are isotherms. A photo-resistive detector 2, Fig. 1, thus scans the field by means of electro-optical scanning means 4. Since the signal to noise ratio of the detection output is a maximum at only one observed temperature, which temperature may be different for that being plotted, the detector is connected with biasing means 10, whereby its characteristic can be shifted to bring the optimum temperature equal to that being investigated. The photo-resistive detector 2, Fig. 2, may be contained in a resistive bridge with means 10 including a variable resistor calibrated in temperature. By this means the variation of the output of detector 2 (or bridge) is very much less than the corresponding possible variation of temperature. A non- saturable amplifier 20 receives the output of the detector and passes to a series of amplifiers 22/24 each preceded by a limiter 26/28 ensuring that the amplifier is never saturated. The temperature being investigated corresponds in the output, Fig. 3a, of the amplifiers, to a voltage between limits Ni and Ns. A selector 30, Fig. 4, thus splits the output Fig. 3a into that part, Fig. 3b, occurring between said limits and that part occurring above limit Ns. The latter part is inverted in means 40 to produce Fig. 3c and is then subtracted from Fig. 3b in means 32 (with 36 closed) to give an output, Fig. 3d, showing large peaks where the output was within the limits and indicating the temperature being plotted. Such an output can be fed to the brightness control of the C.R.T. 8 to produce the isotherm, a background of the entire thermal picture being added with the closing of 41. In the selector of Fig. 4 input Fig. 3a appears at input 45, output Fig. 3b appears at 32<SP>1</SP> and inversion of Fig. 3c appears at 40<SP>1</SP>. For (t 0  - t 1 ) the input voltage fails to break down any of the diodes D 1 , D 2  or D 3  and the outputs are at biasing voltages Ni and Ns respectively established by sources 42 and 47. Between t 1 -t 2  D 1  but not D 2  or D 3  breaks down and the output at 321 follows the input between t 2 -t 3 , all the diodes break down, output 32<SP>1</SP> is held to Ns and output 40<SP>1</SP> follows the input. A transistor version of means 30 (Fig. 5, not shown) is given

For example, a sheet separator roller and a stacking roller may be longitudinally adjustable and form a group. Lateral abutments for the sheet pile, for sheets being forwarded therefrom, and for the sheet stack, may be positioned one of each on each side cf the sheet path, all those on one side of the path forming a group. The adjustment drive means may comprise threaded spindles rotated by handles. Alternatively, drive may be by a stepping motor having an electrical control system. Adjustment may be initiated after changing the format of sheets or web, or by sensing devices such as photoelectric detectors which sense any change in the width of a web or sheets. Adjustment of elements on one side of the feed path may automatically cause equal and opposite or proportional and opposite adjustment of elements on the other side of the path in the case of format change, but not in the case of small variations from mean tolerance value.

Abstract: 1369984 Coiling helices POST OFFICE 19 Nov 1971 [28 Sept 1970] 46120/70 Heading B3E [Also in Division H1] A method of producing the helical winding of a waveguide comprises using a rotatable right cylindrical mandrel 1, a carriage 4 slidable on the mandrel and prevented from rotating therewith by a guide 12 parallel to the mandrel, and means for controlling the angle at which a wire from the carriage approaches the plane perpendicular to the mandrel and passing through the first point of contact of the wire and mandrel. In Fig. 1, the mandrel is vertical and the carriage has jaws 5 resting on part of the uppermost turn of the wire. The wire feedstock passes over a pulley 9 adjustable on an arm 10 depending from the carriage. The jaws 5 may be set by screws 6 (if the mandrel is cylindrical) or may be spring urged to engage the mandrel. A precision sleeve 14 is attached to the mandrel. Fibreglass tape impregnated with epoxy resin mixed with fine iron powder or graphite powder is wrapped around the winding and provides a lossy dielectric. Carbon fibre rovings may also be added to the fibreglass. After curing, the mandrel and sleeve are withdrawn to leave a socket at one end of the waveguide. A corresponding spigot may be formed on the other end by injection moulding, or by machine forming before withdrawal of the mandrel.
