IPC: G01N30/34
Filed: 1967-11-16
Abstract: 1,238,654. Liquid chromatography. UNILEVER Ltd. 8 Nov., 1968 [16 Nov., 1967], No. 52292/67. Heading B1X. A liquid chromatography system in which the relative polarity between mobile and stationary phases is variable, and which is suitable for use in separating samples of any polarity, is illustrated in self-explanatory Fig. 4. Thus, columns A and B comprise support material, e.g. diatomaceous earth, supplied respectively with non-polar and polar stationary phases. According to its nature, the sample to be separated is injected on to either column A or B and that column is then supplied with a mobile phase of opposite polarity to that of the stationary phase or with a solvent of intermediate polarity. Mixer 14 can be controlled or programmed to allow the mobile phase to be of stepwise-varied composition, or of continuously varied composition. Before passing to the column to elute the sample into its constituents, the mobile phase is passed through saturator 10 where it is saturated with stationary phase. When the non-polar stationary or mobile phase is iso-octane, a suitable polar mobile or stationary phase is water; acetone is then a suitable solvent of intermediate polarity.

Abstract: 1,251,298. Piecing arrangement. ALTAISKY POLITEKHNICHESKY INSTITUT IM.I.I. POLZUNOVA. 4 March, 1969, No. 11359/69. Heading D1D. Automatic piecing apparatus for spinning and twisting machines comprises plates 5, 6 see also Fig. 1 not shown, which define a V-shaped slot through which the yarn 8 normally runs and in which a broken end is caught, a piecing roller 2 for moving the broken end to the roving issueing from the drafting rollers, the piecing roller being located so that a tangent to the roller from the apex of the V- shaped slot is at an acute angle α to the plates 5, 6 so that the yarn end can be released from the V-slot and means to remove the released yarn end from the slot.  When a yarn breaks and the end catches in the V-shaped slot the plates 5, 6 are rotated about a pivot 55 which carries their mounting body 4. This movement opens a nozzle 38 to atmosphere and through a pneumatic control system, see Fig. 4 not shown, this causes a piston rod 43 to move to the right when viewed as in Fig. 2. Roller 2 is rotatably mounted on a body portion 11 which in turn is rotatably mounted on a lever 54 rotatable about a pivot 47. As shaft 43 is moved to the right lever 54 which is pivotally attached to it is raised. At the same time a flexible member 45 secured at one end to shaft 43 and wrapped at its other end about a pulley on body 11, causes the body 11 to be rotated anticlockwise against a spiral spring so that roller 2 engages the yarn end held by the V-shaped slot and moves it against drafting roller 61. The yarn end is now held against the roving with which it becomes twisted and it is forwarded by the rotation of roller 61 so that it is broken away, from the portion held by the V-shaped slot, a short piece of yarn being left in the slot. The release of yarn tension on plates 5, 6 allows them to be moved by spring 40 and close the nozzle 38. This actuates a series of operations in the pneumatic control system which results in the rod 43 being moved to the left after an adjustable time delay and the parts 54 and 11 returning to their initial positions. In addition a pneumatically operated plunger moves to move plate 5 away from plate 6 against a spring see Fig. 3 not shown and air is fed to a nozzle 12 to blow the piece of yarn in the slot, clear of the machine. Normal operation is thus resumed. The roving is reciprocated laterally of the drafting rollers and the apparatus shown in Fig. 2 is mounted on a bar 49 which is reciprocated in synchronism with the roving so that the broken yarn end is also brought into engagement with the roving end. All the piecing apparatus in a machine may be lifted by a central control for the doffing and donning operation.

Abstract: 1,252,611. Calculating apparatus. A.SAXON, and H. J. T. CLEMENTS. 21 Jan., 1970 [21 Jan., 1969], No. 3345/69. Heading G4B. A calculator for the fertile period in a female menstrual cycle comprises a pair of flat rotatable indicating members 6 pivotally secured one to each of the holes 5 in a base 1, and a flat calender disc 14 placed over the indicators 6 and rotatably secured to the base 1 at hole 4. An opaque smaller disc is secured concentrically to the under surface of transparent disc 14 so that the circumferential portion 16 which bears the scale is left transparent. A radial edge surface 11<SP>1</SP> of one indicating member 6 is curved so that when it abuts the straight surface 11 of the second indicating member a small angle sector 12 of the base 1 is exposed, corresponding to five days of scale 16. A woman whose menstrual cycle is of constant length aligns the mark 10 of each indicating member 6 with the number on scales 19 corresponding to the length of her period. Calender disc 14 is then rotated until the date of the start of the current period is aligned with the start mark 17. The five day fertile period is then indicated by the gap between members 6, the portion 18 of the base visible through this gap being coloured red to add emphasis.  If the length of the menstrual period is irregular the left hand indicator is set to its minimum duration whilst the right hand indicator is set to its maximum duration. The gap between the indicating members thus widens by an amount equivalent to the difference between the maximum and minimum periods, thus ensuring that the fertile period falls within the days indicated in red at 18. The indicators 6 are frictionally held in their set positions so that the fertile periods of future cycles are shown merely by rotating disk 14. The calculator may be constructed from rigid P.V.C.

Abstract: 1,256,571. Forming non-woven mats. W. H. W. SCHULLER. 28 Feb., 1969 [7 March, 1968], No. 10790/69. Headings D1L, D1N and D1R. A non-woven fibrous web is formed on a moving foraminous surface 5 by advancing a stream 7 of staplefibres (e.g. glass) into the path of a spray of liquid (e.g. water) which is directed against the surface 5. A tube 8 having a longitudinal row of apertures is preferably oscillated in direction AB across the width of surface 5 such that the droplets of liquid move faster than the stream of fibres are fed from conveyor 2. Side walls 13 are washed with liquid from spray tubes 14 to remove fibres deposited thereon. Beneath the surface 5 suction channels 16 are provided through which the liquid is drained for recirculation to conduit 9. An exhauster 17 may provide air suction beneath the surface. Fibres may be fed from both sides of the belt into a spray produced from two sets of stationary nozzles 24 and 22a, 22b which propel liquid vertically downwards and at an angle across the surface respectively. Alternatively the fibres may be fed through one central conduit 39, nozzles 43a, 43b beneath the conduit being traversed in direction IK in unison and having baffles 42, 48 to protect the fibre stream against immediate contact with the spray. The spray tube may be stationary and at an acute angle to the direction of travel of the surface, with the stream of fibres supplied from both sides of the surface. The tube can extend transversely of the surface rather than parallel thereto as shown. Two rows of nozzles may be provided in the tube, with nozzles of one row being spaced between nozzles in the other row. Binders, impregnating agents and dyes may be added to the liquid, or the mat may be passed through a binder or dye bath after moisture has been withdrawn therefrom.

Abstract: 1,259,571. Skittle alley scoring. BRUNSWICK CORP. 27 Jan., 1970, No. 3973/70. Heading A6D. [Also in Divisions G4 and G6] Scores based on pin fall values and the rules of the game are printed on a sheet by printing means on a carriage which swings about a pivot axis, the position of the carriage relative to the axis being adjustable, so as to allow printing of cumulative scores in respect of different bowlers. Pin-fall may be entered manually (Fig. 28, not shown), or automatically from a scanning device which energises an electromagnet at the detection of each fallen pin. Information such as bowler, team and lane, is entered by keys. The score-sheet Fig. 1, is for six players and ten frames. Column 2 is for symbols such as foul, split, chop; column 3 is for first ball pin fall. Column 4 registers the total for first and second pin falls. Column 5 registers the completed frame scores, which because of the rules of the game may be printed one or even two frames previous to the current frame. The totals are entered in row T. Players do not necessarily play in turn so that flexibility in positioning of the printing mechanism is necessary. The print wheels 71-76 are mounted in a carriage 96 which is adjustable across the machine and therefore relative to the record supporting surface 92 according to the number of the player. The carriage 96 is movable horizontally relative to a shaft 99 and rotated round the shaft to bring the print wheels successively on to the record card. This horizontal displacement selects the line to be recorded and is determined by the differential rotation of blocking plate 824. To print in a previous frame position, i.e. after a "strike" or a "spare" a shaft 834 is moved to stop blocking plate 824 one or two increments as the case may be. The storing and computing of scores is as described in Specification 3999/70. Reference is made to Specifications 1,065,061 to 1,065,606. Split is detected as described in Specification 4000/70.

Abstract: 1288792 Digital ohmmeter HICKOK ELECTRICAL INSTRUMENT CO 10 Oct 1969 [11 Oct 1968] 49964/69 Heading G1U A digital ohmmeter comprises an automatically adjustable Wheatstone bridge, an amplifier receiving an input which is a function of the difference in voltage across the unknown resistor arm and the balance arm of the bridge and supplying an output to a voltage-frequency converter, a frequencyresistance converter for converting the frequency. to an apparent resistance forming the balance arm of the bridge and a gate circuit opened for a specific time to pass the pulse output of the voltage frequency converter to a digital display. The time period is selected such that the number displayed when the bridge is balanced is the ohmic value of the unknown resistor. The voltage E c  across the unknown resistor arm CD and that Ef across the balance arm AB are separately integrated in units 34, 37 and applied to a photo-resistance chopper 35 operated from neon light source 40. The chopper output is combined and applied via a capacitor to the input of high gain amplifier 10 as an AC input having value which is a function of the difference between the signals. The amplifier output is synchronously demodulated 52 by further photo-resistors operated from the light source 40 and the resulting DC signal is applied to the input of a DC to frequency converter 11. The frequency of the pulse output from the converter is halved in the flip-flop Q15, Q16 which supplies an output to control the frequency-resistance converter 12 and to an output gate 14. The frequency resistance converter comprises a capacitor connected across the terminals AB via a charge and discharge transistor switching circuit operating at the frequency of the applied pulse signal. The arrangement represents a balance arm equivalent resistance Rf = 1/cf where C +f are the values of the known capacitor and input pulse frequency respectively. The flip-flop output is also supplied to the gate and at balance of the bridge this frequency is proportional to the value of the unknown resistor Rx. The gate is opened for a chosen period of 100 ms. and during this time the number of pulses passing through the gate to a digital totalizer equals the ohmic value of the resistor Rx. Switching circuits are provided for varying the ratio arm resistors, the bridge supply and the capacitive component of the frequency-resistance converter for each decade range of the instrument.
