Filed: 1938-07-04
Abstract: 516,685. Recording  apparatus. SIEMENS & HALSKE AKT.-GES. July 4, 1938, No: 19779. Convention date, July 23, 1937. [Class 106 (iv) ] [Also in Group XXXVI] Apparatus for the automatic graphic recording of vector loci in respect of alternating- current values comprises an automatic complex alternating-current compensator having one of its variable elements connected to a recording pen and the other to a writing surface, the movements transmitted being at right-angles. The compensator K is connected through a crosscoil instrument S to the supply circuit which feeds, through transformer T, currents in quadrature to slide wires Rl, R2. Contacts Kl, K2 are driven from the rotors of induction meter motors A, B, the voltage winding of which are fed with currents displaced 90 degrees from phase - shifters Ph, the series - connected current windings being supplied through an amplifier having an input proportional to' the voltage set up in the coil SD of instrument S. As the coil SD swings, the balancing potentials effecting compensation cause the contacts Kl, K2 to vary, and these contacts are geared to a pen F and recording strip P. The storage rollers D of the recording strip are under torque in opposite directions produced by two induction motors (not shown) this arrangement maintaining the strip P taut.

Title: Improvements in and relating to prepayment mechanism
IPC: G07F15/00
Filed: 1933-07-14
Abstract: 422,276. Prepayment mechanism for meters. HOLDEN, F., and MEASUREMENT, Ltd., Terminal House, Lower Belgrave Street, London. July 14, 1933, No. 19944. [Class 27] In a prepayment meter in which a continuously rotating motor is operating to deduct from the prepayments basic charges, such as rent, a shaft a, Figs. 1 and 4, is rotated in opposite directions, through the usual differential mechan. ism, by prepayment and by the consumption meter and continuously rotating motor respectively. The shaft a drives by wheels b, c a parallel shaft d having wheels e, f gearing with wheels j, g to drive respectively two cams m, i loosely mounted on the shaft a, the cam i being the slower moving cam and being integral with a member having a peripheral cam groove h. A blade o carried by a shaft n coacts with the cams i, m, the shaft n carrying also a collar s having a tooth or notch t engaged by a detent u, Figs. 1 and 3, on an arm v pivoted at w and rigid with a second arm v<1> carrying a spring x and a tooth y which holds a switch arm z in closed position by engaging its upper end 2. A spring tends to rock the arm z in a clockwise direction to open contacts 8, 9, the arm z pressing against the spring x and by means of the detent u tending to rotate the shaft n in an anti-clockwise direction against the action of a counterweighted arm p, q. When the cams m i move clear of the blade o, the shaft n is rocked and releases the switch arm z, the cams being so co-related that the cam i moves clear of the blade before the cam m in order that release of the switch is always effected by the fast moving cam. When the switch is opened, the shaft n is moved axially to carry the blade o out of the path of the cam m to render this inoperative for holding the switch in closed position and to allow the rent charge motor to increase the debit charge against the prepayment mechanism. This is effected by the cam groove h which engages a pin 6 on a sleeve 3, Fig. 3, loose on the shaft n and located between the collar s and the boss o <1> of the blade o, the sleeve 3 being prevented from rotating by blades 4, 5 engaging the periphery of the grooved member. Indicators.-A disc 10, Fig. 5, on the shaft a has a notch 11 which engages a pin 12 on a counterweighted indicating finger 13. The disc 10 turns in one or other direction from its neutral position according as the prepayment mechanism is in credit or is in debit due to rent charges and this turning of the disc moves the finger 13 to one side or other to indicate debit or credit, the amount of which is shown by markings on the disc in conjunction with a fixed pointer 15.

Title: Improvements in or relating to machines for forming cartons
IPC: B31B3/32
Filed: 1959-12-11
Abstract: 938,578. Carton making machines. CARTONMASTER (DISTRIBUTORS) Ltd., and E. J. E. POWELL. July 27, 1960 [June 11, 1959(2); Dec. 11, 1959], Nos. 19975/59, 19976/59 and 19977/59. Class 18. A machine for making cartons that are heat sealed comprises a plurality of non-rotatable formers around which a blank is wrapped, the formers being mounted on a rotatable table or endless chain, means for heat sealing the longitudinal seam, means for forming and assembling a flanged cap, and an expanding mandrel which facilitates the sealing of the cap. The machine revolves around a central shaft and is driven either continuously or intermittently by means of a Geneva motion. In one embodiment Fig. 1, the blanks are fed from a conveyer on to a flyer 27 pivoted at 28 which passes the blanks to a vertical position against one of the formers 3, a clamp 4 being temporarily raised by means of a cam track 11 and follower 10. Clamps 4 and 5 fold the blank round the former so that the longitudinal edges overlap, the clamp 5 being controlled by a cam track 19 and follower 18. An electrically heated pressure member 21 moved by another cam track 25 and follower 24 effects the sealing. In a modification, the flyers 27 are replaced by suction means on the clamps 4. The former 3 is hollow and accommodates the shaft 30 of the expanding mandrel 32, the expanding movement being effected from a cam track 39 by members 38, 36 and 33. A spring-loaded cam controlled plunger 40 carries a cupped die 50 which appplies and forms one end closure. A cam 48 raises the die against the end of the mandrel and carton body and a cam 45 slides, or swings, the plunger in a horizontal plane to allow the carton to be removed by mechanical or pneumatic means to a conveyer. Either the mandrel or the die 50 may be heated electrically. The mandrel, Fig. 3, is expanded by a cam 61 and segments 54 have interengaging fingers so that there is no gap between the segments when expanded, the edges 59 may be toothed, grooved, and/or rubber clothed. Alternatively, the mandrel may be expanded by hydraulic or pneumatic means. Instead of a cap type closure, a push-in type may be fitted instead. In a second embodiment, Fig. 6, for applying the push-in type of end closure. an electric motor drives a gear 67 to cause rotation of tables 65, 66. The table 66 carrier has a number of carton supporting members 68 raised by a cam track 71. The table 65 carries capping heads 75 moved vertically by a cam 78. An expanding mandrel 82 is housed within the head and is operated by a cam 85 and follower 84.

Title: Improvements in the production of ballast-free potassium ammonium nitrate
Inventor: HAMPRECHT GUENTHER
IPC: C05C1/00
Filed: 1959-06-11
Abstract: A ballast-free potassium ammonium nitrate is prepared by alternately treating a cationexchanger with an aqueous solution of potassium chloride and then regenerating the exchanger with aqueous nitric acid in a series of columns, in which a portion of the regeneration solution is withdrawn, whilst still incompletely reacted, from the effluent of each of the columns, combining the withdrawn portions, neutralising the combined solution with ammonia, and evaporating to obtain a solid product.  The total solution withdrawn in one cycle is such that it contains an amount of potassium nitrate equivalent to the capacity of one column, and such an amount of nitric acid that, after neutralisation with ammonia, the product has the desired N:K2O ratio, preferably 1:1.4 to 1:1.5.  The solution remaining after a portion has been withdrawn is replenished with nitric acid before being passed to the next column.  In an example the cation exchanger employed is a nuclearly sulphonated styrene divinylbenzene copolymer. The statement of prior art refers to a manner of preparing potassium nitrate by treating an aqueous potassium chloride solution with a cation exchanger and regenerating the exchanger with aqueous nitric acid in a plurality of series-connected columns through which the potassium chloride or nitric acid are passed.  At the end of each column the top fraction (i.e. that part of the issuing solution which contains practically no potassium ions in the case of the passage of potassium chloride through the exchanger when charged with hydrogen, or that which contains practically no hydrogen ions in the case of the passage of nitric acid through the exchanger when charged with potassium) is withdrawn from the cycle for further processing, while the remaining fraction of the solution is fed to the next column, together with an amount of fresh potassium chloride or nitric acid equivalent to the top fraction withdrawn.ALSO:A fertilizer consisting of a potassium ammonium nitrate and a phosphate may be prepared by alternately treating a cation exchanger with an aqueous potassium chloride solution and then regenerating the exchanger with aqueous nitric acid in a series of columns, in which a portion of the regeneration solution is withdrawn, whilst still incompletely reacted, from the effluent from each of the columns, combining the withdrawn portions, adding thereto phosphates, which are preferably water- or citrate-soluble, neutralising with ammonia, and evaporating to obtain a solid product.

Title: Improvements in or relating to radiographic examination techniques
Inventor: COTTERELL KENNETH
IPC: H04N5/32
Filed: 1962-05-24
Abstract: 1,038,711. Point-by-point radiographic examination. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 17, 1963 [May 24, 1962], No. 20050/62. Heading H4F. A specimen 1, Fig. 1, for example a fuel element of an atomic reactor, is rotated by a motor M and examined point-by-point by an X-ray source 2 in conjunction with a radiation detector 11, 12 (a scintillation crystal and photomultiplier) which are traversed axially of the specimen by a threaded shaft 6, signals from the detector being applied through processing circuit 13 to a facsimile type of recorder 14 which is driven in synchronism with the scanning by a coupling 17 from motor M. 8 and 10 are lead collimating elements. The invention may use gamma rays in place of X-rays as illustrated, and may also extend to examination by radiation emitted from a specimen. In the processing circuits, Fig. 2, the signals from the scintillator and photomultiplier 11, 12 are applied via a cathode-follower 20 and pulse amplifier 21 to a sealer 22. The sealer may then be used selectively to operate the recorder either by way of pulse generator 23 and power amplifier 24 (so as to produce a half-tone type of record with variable dot spacing) or by way of a ratemeter 25 and amplifying system 26-31 (so as to produce a continuous tone type of record). In system 26-31, the ratemeter output modulates a signal from oscillator 27, the signal being amplified at 28 and 29 and then rectified at 30. An adjustable bias 31 and an adjustable gain control in amplifier 28 permits the effective range of recorded signal to be adjusted and unwanted (i.e. background radiation) counts to be eliminated. Reference is made to the examination of specimens in the form of plates.

Title: Improvements in or relating to Nuclear Explosion Detection Systems
Inventor: HICKS GORDON GRAHAM
IPC: G21D5/00
Filed: 1966-05-06
Abstract: 1,165,331. Detecting nuclear explosions. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 25, 1967 [May 6, 1966], No. 20289/66. Heading G1A. A nuclear explosion is indicated in response to the production of three electrical pulses in a predetermined time sequence from the characteristic radio-frequency and optical radiations from such an explosion, the first pulse P1 being derived from the r.f. signal when its rate of rise exceeds a predetermined value, its duration is less than a predetermined time, and its field strength exceeds a predetermined level, the second P2 from the characteristic fast-rising portion of the optical radiation when its rate of rise exceeds a predetermined value and its duration is less than a predetermined time, and the third P3 from a slow-rising portion of the optical radiation when the rate of rise exceeds a predetermined value and its duration exceeds a predetermined time. Characteristic wave forms are shown in Figs. 1 and 2, the time interval. T on the graph of optical radiation being used to provide in addition an indication of the yield. A rod aerial 1, Fig. 3, and a coupled broad-band emitter follower 2 are coupled by cable to remote and protected circuitry in which the signal is applied to parallel paths, in one of which its level is detected in a Schmitt circuit 6 to produce a pulse P4 corresponding to the leading edge of the Schmitt pulse, and in the other of which, a pulse P6 is produced if the rate of rise is adequate to operate a Schmitt circuit 11 and its duration is less than that of a pulse applied to an "and" gate 13 by a generator 12. The optical transient is detected by a pair of detectors each comprising five photo-voltaic cells connected in parallel and mounted with their sensitive surfaces in the vertical plane on the periphery of a horizontal circle and between two plates which limit the angle of vertical coverage to 20 degrees. The cells are connected to their respective analyzing circuits via low resistance transformer circuits to give a linear response, and the pulse P2, together with pulse P1, derived from the coincident presences of P4 and P6 in the r.f. circuit, develops a pulse P9 to produce a pulse P3 from an "and" gate 35 whereby the time of a clock 41 is stored in a binary store 47 and indicated in a unit 43. The pulse P2 from the fast-rising portion of the optical portion may be produced through a rate-of-rise circuit 20, or through a level circuit 25 if the light cells are saturated. The yield is determined by a milli-second stop-clock in unit 37 which is started, after a delay of 80 m/sec. in unit 36, by the pulse from "and" gate 24 when pulses P1 and P2 are present, and stopped by pulse P3, the delay compensating for P3 occurring at least 80 m/secs. after point C of the curve in Fig. 2. Resetting arrangements are described and circuit component values and operating times are exemplified. The arrangement is aimed at preventing false operation by lightning.

Patent GB-446614-A (GB)
Title: Improvements in the manufacture of aliphatic alcohols
IPC: C07C29/04
Filed: 1935-07-17
Abstract: <PICT:0446614/IV/1> Alcohols are produced from ethylene or propylene by absorption in sulphuric acid, under suitable conditions so as to obtain an acid reaction mixture containing a substantial proportion of dialkyl sulphate, distilling off the dialkyl sulphate under reduced pressure, such as 20 mm. and hydrolyzing the dialkyl sulphate, the dilute acid remaining after the separation of the alcohol being capable of reconcentration without loss as it is free from carbon. The absorption of ethylene may be effected with sulphuric acid of 95--96 per cent at 70--80 DEG  C. under pressure such as 300 lbs. When in the course of the process carbonaceous materials accumulate in the reaction liquor, it may be diluted and hydrolyzed in the usual manner and the alcohol distilled off; a large proportion of the carbonaceous materials can then be mechanically separated for instance by a sand filter before reconcentrating the acid.  Preferably, the absorption of ethylene is stopped when about 1,5 molecules have been absorbed per molecule of sulphuric acid, using 96 per cent acid at 80 DEG  C.; with 98--100 per cent acid the amount absorbed may be 1,75--1,8 molecules.  In an example, ethylene is absorbed in sulphuric acid in an absorber 4, the gas entering at 6.  The absorption liquor is taken through a pipe 9 to a tower or chamber 11 to allow dissolved gas to escape by a pipe 12; the liquor then passes to a vacuum still 15 of suitable type, the diethyl sulphate vapour being condensed at 18 and led to a hydrolyzer 35, alcohol being separated in a still 31.  The residual acid from the still 15 may be led back to the absorber 4 or passed to a hydrolyzer 26, the alcohol being distilled off in the still 31.  Specifications 157,578, 175,077, and 336,681, [all in Class 2 (iii)], are referred to.
