Abstract: 798,615. Dispensing paper cups; vending apparatus. AMERICAN CAN CO. Aug. 29, 1956 [Sept. 1, 1955], No. 26426/56. Classes 27 and 116 [Also in Group XXX] A container dispenser which may be coin freed has dispensing elements 9 mounted on a support 1 and arranged to feed containers e.g. paper cups through an aperture 7 in the support, the elements being adjustable in position to deal with containers of different sizes. A magazine 6 containing a stack of rim-beaded paper cups 8 is mounted on a plate 1 over the aperture 7 about which is positioned a set of rotary dispensing worms 9, each having an upper journal 10 and a lower journal 11 above which is an integral pinion 12. Each worm has a flat top face and a knife-edge 14 at the starting-point, and a groove 15 ending in a flat projecting land 16 having a curved outer edge. A driving motor 4 has an upstanding shaft 18 journalled in the plates 1 and 2, provided with a pinion 19 meshing with an idler gear 20 carried on a shaft having a journal pin 22 at each end for engagement in apertures in the plates 1 and 2. The gear 20 drives a ring gear 23 which has a hollow portion 24 depending through an aperture 25 in the plate 2 and meshes with the pinion 12 on each of the dispensing worms 9, thus driving them in unison. The first operation causes the knife-edges 14 to engage the lowermost cup above the rim-bead, place the bead in the grooves 15 and transfer the cup downwards during a single revolution until its rim bead rests on the flat lands 16. The next cup in the stack is maintained above by the flat tops 13 until the succeeding operation, when the first cup is discharged after the worms have turned 15 to 20 degrees, the next cup being lowered on to the lands 16. In order to accommodate paper cups' of different sizes, there are alternative sets of apertures 28 and 29 for the dispensing worms and 31 and 32 for the drive gears; larger ring gears are provided for use when these are employed.

Title: Improvements in or relating to a process for the treatment of gases obtained by hydrocarbon pyrolysis
IPC: C07C7/11
Filed: 1957-08-23
Abstract: Gases obtained by pyrolysis of hydrocarbons are treated to obtain acetylene and olefines separately in a substantially pure state by first washing the pyrolysis gas with liquid ammonia under atmospheric pressure and at - 70 DEG  C. to - 60 DEG  C. to form an ammoniacal solution containing substantially all of the acetylene and only a minor quantity of the olefines, and leaving a gas rich in olefinic hydrocarbons and substantially free from acetylene, compressing the ammoniacal solution to a pressure of several atmospheres and then subjecting it to a partial reduction of pressure at a temperature in the range of 25 DEG  C. to 40 DEG  C., thereby desorbing the olefines with a small quantity of acetylene which are returned to the washing zone and leaving an ammoniacal solution of acetylene substantially free from olefines, and thereafter distilling the ammoniacal solution to separate the acetylene from the ammonia.  In an example a gas mixture obtained by the pyrolysis of light petrol containing 7% acetylene, 6% propylene and 16.5% of ethylene is treated at - 70 DEG C. at atmospheric pressure.  The ammoniacal solution is compressed to 18 atmospheres and is then partially desorbed at 40 DEG  C. and then distilled to give 99.9% acetylene.  The gas issuing from the absorption tower comprises propylene and ethylene together with some acetylene and also ammonia which is removed by sulphuric acid treatment.

Abstract: 1443180 Automatic control of conveyers BRITISH STEEL CORP 4 June 1974 [6 June 1973] 26940/73 Heading G3R In a system in which material is conveyed from a first container 3 to a second container 1 from which it is continuously discharged, the rate of discharge from the first is controlled in accordance with a determination of any deficit or excess weight of material in transit and the measured weight of material in the second container so as to maintain a desired value for the said weight in the second container. The discharge rate from 3 is is measured by a belt weigher 8 whose output on line 19 is compared at 18, Fig. 2 with the required discharge from 1 calculated according to the measured speed of 12 and related parameters and manually or automatically supplied at 20. Any difference (which indicates that an excess or deficit will ultimately occur) is supplied to a summer 21 directly and negatively via a delay 22 equal to the transit time of the material. The output of 21 is integrated at 23, a proportion of the output of which is fed back to 21 to eliminate drift. The output of integrator 23 is the excess or deficient weight of material in transit, and this is combined at 27 with the output of load cell weighers 13 on container 1. The output of 27 is compared at 29 with the desired value for the weight of 1 and any difference used to adjust the set value for a material feed controller 15 at container 3. In the embodiment, the material in 3 is ore, which is combined with coke from 4 and hot return fires from 5 to supply a sinter strand 12. The flows of coke and fires are controlled in known manner as a set ratio of the flow of ore.

Abstract: 1345045 Polarimeter NIPPON KOGAKU KK 19 April 1971 [16 April 1970] 27165/71 Heading G2J [Also in Division G1] A polarimeter for determining the optical activity of a specimen S comprises a polariser P and analyser A spaced apart along the optical axis of the polarimeter in crossed-Nicol relation, an optical modulator Mo, intermediate the polariser and analyser, a rotatable quarter wave plate Q 2  and a rotatable half wave plate H between the polariser and the modulator, and a photo-electric detector 3 whose output is mixed with the signals representative of the alternating supply to the optical modulator so as to control servomotors 12, 11 to rotate the devices Q 2  and H. The final orientation of the quarter wave plate is indicated at 37 as the angle of elliptical orientation i.e. the rotation produced by the specimen S. The phase difference produced by the specimen is calculated by an arithmetic circuit 30 operating on signals proportional to the orientations of the quarter wave and half wave plates Q 2 , H. The optical path also includes lens system 1, 2, a filter F to provide monochromatic light, a quarter wave plate Q 1  oriented at 45 degrees to the polariser axis. The optical modulator comprises KDP crystals X1 and X2 and intermediate quarter wave plate Q3. The modulator provides cyclical modulation of the angle of orientation and phase of the linear polarisation provided by P. The square wave signals mutually 90 degrees, out-ofphase, supplied to crystals X1 X2 are provided from an oscillater 13, comprising an arrangement of pulse generator, capacitors and bistables, Fig. 2 (not shown). These respective square waves are also applied to synchronous rectifiers 5, 6 in the circuits controlling rotation of the half-and quarter-wave plates H 1  Q 2 , respectively. In operation, the system functions automatically, the light passing the analyser A being detected and the detector output being demodulated at 5, 6 to cause rotation of H and Q 2  to balance the rotation of the polarised beam caused by the sample S and produce a null detector output. The mounting arrangements for H and Q 2  have micro-switches so that if rotation through 45 degrees from the reference direction occurs Figs. 3, 4 (not shown), flip flops 19, 26 are actuated and servomotors 12, 11 are reversed. Potentiometers 28, 29 coupled to the Q 2 , H rotation provide the required signals. The arithmetic circuit 30 comprises resistors and an operational amplifier and the value of phase is indicated at 38.

Abstract: <PICT:0670083/III/1> <PICT:0670083/III/2> <PICT:0670083/III/3> Solutions of solids are dried to give uniform pellets by introducing the solution directly into the interior of a heated, agitated bed of particles established in a cylinder rotating about its longitudinal axis which is disposed approximately horizontal; the operating conditions, and particularly the temperature of the bed and the depth at which the solution is introduced below the surface of the bed, being adjusted so that the peripheral particles are maintained in a dry state.  The process is particularly applicable to the drying of an aqueous solution of calcium chloride, and also to solutions of magnesium chloride, sodium phosphate, and sodium silicate.  A kiln 10 containing a bed 22 of calcium chloride pellets, is rotated, via a chain and sprockets, by motor 18.  The bed is heated to 400 DEG F. by a series of burners 48 (see Group XI) supplied with a mixture of gas and air through conduit 46.  The burners are disposed at an angle of about 20 DEG  with the surface of the bed so that the flames do not actually contact it.  A solution containing approximately 55 per cent by weight of calcium chloride is pumped through pipes 39 and 34 into main feed-pipe 26, and it is then distributed through a series of pipes 24 into the interior of the bed; the points of introduction below the surface of the bed being between 10 to 45 per cent of the depth of the bed.  The kiln discharges the product (pellets having an average diameter between 1/4 inch and 3/4 inch and a density between 1.32 and 1.64 grm./ml. respectively) through cylinder 62 into chamber 64 and chute 67; while combustion gases are discharged through flue 68.  Fresh bed particles may be supplied to the kiln from hopper 73 through chute 71.  The process may be employed to convert material made up of irregular particles of mixed sizes into nearly uniform pellets by dissolving a portion only of the original material in a solvent, feeding the resulting solution to the drying apparatus p while at the same time also feeding the remaining portion of the material as solid particles.
