Patent GB-1088246-A (GB)
Title: A process of producing hypoxanthine
IPC: C07D473/30
Filed: 1964-11-13
Abstract: Hypoxanthine is obtained by subjecting 4-amino-6-hydroxy-5-nitroso pyrimidine or salt thereof to reduction with a reducing agent to convert the nitroso group to amino to form the corresponding 4,5-diamino compound and subjecting the latter to imidazole ring closure by means of formamide to convert it to hypoxanthine, the reaction being carried out in the presence of formamide and without isolation of any intermediate product.  The 4-amino-6-hydroxy -5-nitroso-pyrimidine or salt thereof may be obtained by subjecting 4-amino-6-hydroxy -pyrimidine or salt thereof to nitrosation by means of a nitrosating agent in the presence of formamide and is then directly reduced without isolation.  The nitrosation may be carried out either (a) by adding a stirred solution or suspension containing a nitrite, e.g. ammonium, sodium or potassium nitrite, in formamide to the 4-amino-6-hydroxy pyrimidine or salt (e.g. Na salt) thereof, followed by dropwise addition of formic, acetic or mineral acid (e.g. HCl or H SO4) while stirring, or (b) by passing gaseous HNO2 through 4-amino-6-hydroxy-pyrimidine or a salt thereof (e.g. Na salt) together with an acid to free the 4-amino-6-hydroxypyrimidin from the salt.  The reduction of the nitroso compounds may be carried out by treating with a suitable reducing agent or by hydrogenation in the presence of a catalyst.  Several suitable reducing agents are specified including sodium hydrosulphite, sodium thiosulphate, potassium sulphite, organic dithionites, sodium sulphide, ammonium hydrosulphide or polysulphide, sodium bisulphite, hydrazine sulphate or hydrate, formaldehyde-sodium bisulphite, stannous chloride, aluminium amalgam, and various catalytic hydrogenation procedures are also specified. The final ring closing reaction is suitably effected at above 150 DEG  C. and the entire process is preferably carried out in an inert atmosphere, e.g. nitrogen.

Abstract: 1481239 Burner controls RINNAI KK 28 Oct 1974 [26 Oct 1973 (2)] 46606/74 Heading F4T An apparatus for cooking under pressure comprises a pressure cooker 1, a source of heat 9 and a timer 19, which latter starts when a predetermined pressure of temperature in the cooker is reached, and terminates the supply of heat after a predetermined time. A casing 6 secured to the bottom of the cooker encloses two thermal-sensitive detectors 7, 8, and gas is supplied to burner 9 via electromagnetic valves 11, 12, having a by-pass 13, and a pushbutton operated valve 14 also connected to a pilot burner 15. Timer 19 is connected to valves 11, 12, pilot lamps 20, 21, 22, and switches 23, 24. In operation, with pilot 15 alight, gas being supplied to valve 12 and switches 23 closed, an electric current passes through pilot lamp 20 to light it. Change-over switch 24 is actuated to arrange for fluid to be left in the cooker at the completion of cooking, pilot lamp 21 is lit, valves 11, 12, are opened and burner 9 is lit by pilot 15. When the pressure in the cooker reaches a "set" value, thermal detector 7 is actuated to close valve 11 and to actuate timer switch 19 which has previously been set for a predetermined time. Gas flows to burner 9 through by-pass 13 so as to maintain the pressure in the cooker, until the timer closes valve 12 to shut-off burner 9. If no fluid is required in the cooker at the end of the cooking period switch 24 is operated to light pilot lamp 22 and to open valves 11, 12. When the set pressure is reached, thermal sensor 7 closes valve 11 and when the cooking period is complete and the fluid has boiled away, sensor 8 closes valve 12 to shut-off burner 9. Temperature sensors 7, 8, may be replaced by pressure detectors in the cooker. In a modification, the gas burner may have a constant size flame, and sensor 7 only actuates the timer and does not reduce the flame. Sensor 8 will over-ride the timer.

Title: Improvements in an automatic filter plate moving apparatus in a filter press
IPC: B01D25/172
Filed: 1964-11-19
Abstract: 1,091,680. Filter press plate moving apparatus. K.-I. KURITA. Nov. 19, 1964 [June 9, 1964], No. 47196/64. Heading B1D. [Also in Division B8] Plate moving apparatus in a filter press comprising plates 11 consists of rotatable horizontally staggered pawls 34 and 40 attached to chain lugs 32 which are on both sides of the press and are moving to the right, which pawls slide under extensions of the filter plates (Fig. 4) until they come to the end plate (Fig. 3) whereupon they rotate upwards urged by springs 36 and 42 respectively and engage with the extensions thus moving the plate. Thus as lug 32 passes the end filter plate, cam 38 which has been held down by plate extension 39 is free to move upwards when it has passed the end of the extension (Fig. 3) thus allowing attached main pawl 34 to rotate upwards and engage the shaded part of the plate under the extension. When auxiliary pawl 40 passes the end of the extension 39 of the penultimate plate (situation not shown) pawl 60 also rotates upwards and engages the L.H. side of the end plate extension. On reaching the other end, cam 38 is forced down by the extensions of already moved plates or a movable piston head (28), (Fig. 1, not shown), thus disengaging pawl 34, and pawl 40 urges the disengaged plate against the already moved plates before passing on. The moved plates are returned by the piston head (28) operated from an oil pressure cylinder (30). The chains containing lugs 32 are moved by an electric motor (16).

Abstract: 1,114,842. Hooks. P. W. BARKER and J. G. PEIRSON. 4 Dec., 1964 [4 Dec., 1963], No. 47955/63. Heading E2A. A hook 1 to be suspended from a cable or swivel by a pin 4 in apertures of a clevis 3 has secured to at least one end of the pin a mounting 5 on which is pivoted a mousing- piece 7, e.g. on a pintle 6. As shown, the piece 7 comprises two parallel plates 15 joined by a cross-member 16 locating on the inside of the hook nose 9 but this member may be replaced by the inturned end of a plate 14 which joins the upper ends of the plates 15 and may extend right down those plates. A spring 8 on the pintle 6 urges the musing-piece 7 to the closed position and is located between two lugs 13, Fig. 3, secured on the mounting 5 for receiving the pintle. Instead of the pintle 6, aligned trunion pins may extend from side flanges 12 of the mounting 5 to form pivots X for the side plates 15. In another embodiment, Figs. 4, 5 (not shown)), a simple curved mousing-piece is pivoted by its eye on a pintle (26) and between lugs of a mounting, the lugs and pintle being located adjacent the bottom of the clevis (3) and the hook neck (2). The mounting in this embodiment may be a simple plate with the lugs at one end and attached at the other end to one end of the clevis pin (4). Alternatively the hook may be so formed that its clevis (3) and pin (4) are generally in a plane perpendicular to the median plane of the hook and the mounting is then a channelform member with its lateral webs supported one by each end of the pin (4).

Abstract: 1,198,618. Polyepisulphide-aminoplast reaction products. DUNLOP CO. Ltd. 24 Oct., 1967 [27 Oct., 1966], No. 48154/66. Heading C3R. [Also in Division B2] Modified polymers of the type claimed in Specification 1,148,652 are prepared by simultaneously reacting together a thermosetting amine-formaldehyde condensation product containing reactive hydroxy groups, an episulphide polymer containing at least 2 hydroxy groups per molecule, and an alcohol, at a pH of less than 7. The episulphide polymers may be prepared as described in Specification 1,109,164, modified, if necessary, to convert the reactive groups to hydroxy groups by, for example, adding formaldehyde to the mixture of aminoplast and episulphide polymer. The aminoplast may be prepared in situ in which case excess formaldehyde is used. The amount of aminoplast is usually from 10 to 250% by weight of the polymer. Suitable alcohols are isopropanol, butanol, amyl alcohol and benzyl alcohol. The amount of alcohol should be more than sufficient to react with the methylol groups in the reaction mixture and to render the reaction product soluble in hydrocarbon solvents. Compositions which may be stored and later used as coatings or adhesives are obtained by stopping the reaction before gelling occurs. Cross-linking is achieved on use by acidifying the composition. Pigments and fillers such as titanium dioxide, carbon black, calcium carbonate, calcium sulphate, barium sulphate and magnesium silicate, and other additives may be mixed with the compositions.

Title: Airborne positioning systems
IPC: G01S13/78
Filed: 1975-11-25
Abstract: 1517329 Radio navigation GRUMMAN AEROSPACE CORP 25 Nov 1975 110 Dec 1974148333/75 Heading H4D A mobile 12, Fig. 1 determines its position by means of sequential usage of a plurality of D.M.E. stations 14A-J (i.e. a Rho-Rho system) and a recursive updating of position and individual station bias data using Kalman or polynomial filter techniques. At the start of a situation an initialization process is activated whereby, for a polynomial filter implementation, all station biases, position, velocity and acceleration corrections together with velocity, and acceleration values, are all set to zero. An arbitrary aircraft position X, Y is assumed - e.g. that of one of the ground stations. For a Kalman filter implementation two stages in the initialization process are needed involving a first stage in which polynomial filter provides the initial position and velocity estimates. The initial data is then recursively updated using corrections #x, #y, #t the time between range measurements and various weighting factors. This enables the range to the next D.E.M. station to be predicted - barometric altitude and assumed station bias also being used for the prediction. The D.M.E. station is then interrogated and the response caught in a range gate (possibly using early and late gate techniques) positioned according to the prediction. The range gate may initially have to be swept if the range estimate is poor. The updating correction values #X, #Y are calculated from the actual range and predicted range and recursively used next time round. The initialization process is completed when the range corrections or residuals #R are 1000ft. or less. The program then switches to recursive updating of the station biases. With a polynomial filter the bias Bi of the i<SP>th</SP> station is, after the Mi<SP>th</SP> interrogation of that station which yields residual #R, updated to i.e. the recursive average of the residuals. With a Kalman filter the biases are updated using the position (as against range) estimates. A flow diagram implementing the above is shown in Fig. 4.

Filed: 1968-10-11
Abstract: 1,215,965. Handling and boxing coin rolls. MILLIKEN INDUSTRIALS CORP. 11 Oct., 1968 [12 Oct., 1967], No. 48392/68. Heading B8C. A coin roll handling machine for boxing coin rolls 22 comprises a coin roll shoot 10, a gate 32 to retain coin rolls in the shoot, a coin roll accumulator 14, and a pusher 12 to supply rolls to the accumulator. The rolls collect behind the gate until a roll is resting on a microswitch 26 to operate a four-way valve through a delay switch and supply air to a double-acting cylinder 56. The pusher 12 is thereby moved rightwards to release a microswitch 86 energizing a three-way valve to raise the coin gate 32, and deposit a predetermined number of rolls on a vertically movable platform 76. The rolls actuate a microswitch 72, causing the platform 76 to rise, and the rolls, projecting at both ends over the respective edges of the platform, force upwards two pivoted spring-loaded flaps 92. When the rolls have cleared the flaps the flaps swing out under the rolls to support them as the platform 76 is lowered. A cam 94 closes a microswitch 74 to reverse the four-way valve, causing the pusher 12 to return leftwards. The microswitch 86 is re-engaged to close the gate 32. The rolls which have been resting on top of the pusher move to refill section 20 of the shoot. The above operation will be repeated until a microswitch 70 is actuated by the top layer of rolls accumulated, causing a ram (78), Fig. 5 (not shown), to push the rolls into a box (80) on a conveyer (16).
