Title: Improvements in or relating to methods and apparatus for dispensing granular material
IPC: B01F15/04
Filed: 1959-06-15
Abstract: 875,939. Weighing and dispensing apparatus. WAHL, E. A. Jan. 15, 1959 [July 1, 1958], No. 20473/59. Class 143 [Also in Group XXX] A batch of granular or like material is weighed in a de-energized, screw conveyer during one portion of a weighing cycle and discharged therefrom by energizing the screw during another portion of the cycle, the discharged batch entering a continuously running screw conveyer by which it is dispensed over a period of time equal to the duration of the weighing cycle. In the system particularly described an automatically controlled batch weight is discharged into the continuously running screw in each of a series of consecutive weighing cycles and the continuously dispensed material emerges at a uniform rate determined by the weight of each batch and the duration of each cycle. Each batch is weighed in a receptacle 18 whose lower portion incorporates a screw 23, the material being fed from a vibrated hopper 53 via a screw feeder 57. When the required batch weight is attained, beam 11 tilts and breaks switch 74 to de-energize simultaneously the vibrator 62 of the hopper and the motor 61 driving the feed screw 57. The batch is discharged by the subsequent energization of a motor 36 which turns a flexible shaft 33 to rotate the screw 23, an eccentrically mounted transverse member 31 on the shaft of the screw assisting the discharge by vibrating the receptacle 18. The weigh beam 11 is clamped during discharge between a pad 39 and the stem 42 of a solenoid 41 energized at the same time as the motor 36. Each complete weighing cycle comprises the time taken for one revolution of a timing motor 78 which rotates cams 79, 81 acting on switches 76, 77 respectively. In each cycle switch 76 is first closed to initiate feed to the weigher, the switch re-opening after the feed has stopped and remaining open while switch 77 is closed to control the discharge. The screw conveyer 571 into which the weigher discharges is of such length that although fed at one end with discrete batches, the material emerges at the other end at a substantially uniform rate. Specification 815,691 is referred to.

Abstract: 891,044. X-ray spectrometers. HILGER & WATTS Ltd. May 23, 1960 [June 19, 1959], No. 21164/59. Class 98(1). [Also in Group XL(b)] An X-ray spectrometer has a radiation detector movable to positions corresponding to preselected parts of the spectrum and programmed switching means for controlling movement of the detector from one position to the next in sequence. Measurement of line intensity. X-rays from a source 1, Fig. 1, pass through a filter 12 to impinge on a scintillometer 11 and a sample 3. Secondary X-rays from sample 3 are collimated and fall on the analysing crystal 31 whence they are diffracted to a second scintillometer 8. Both scintillometers integrate, a pulse from scintillometer 11 at a predetermined count stopping the scintillometer 8 and initiating a print-out. The crystal 6 and scintillometer 8 are on tables 9 and 10 connected by 1:2 gearing to maintain the correct geometrical relation. The filter 12 comprises segments 13, 14 of different density and the crystal 31 a plurality of crystal segments, the segments being selectable by solenoids 25, 34 Fig. 3. Setting up the programme is effected on a six-bank uniselector 50. The first of -contacts 122, 121, 120 are connected to the appropriate one of contacts 179, 125, 124, respectively, to set the tens, units and fiftieths of degree setting for the first spectral line to be measured. The first of contacts 123 is connected to one of contacts 184 to determine the count at which scintillometer 11 produces its stopping pulse. The first of contacts 127, 128 are connected or not to contacts 129, 130 respecuvely according to whether or not the filter and crystal solenoids are to be energized. The procedure is repeated with the second of contacts 123-120, 127, 128 to set the requirements for the second line to be measured. Execution of the programme. Operation of the start button 193 energizes a motor 43 to drive tables 9, 10 and the switch banks 60<SP>1</SP>, 60<SP>11</SP> coupled therewith. These banks make one revolution for one degree movement of table 10 and have 50 contacts. When the wiper 137 reaches contact No. 49 of bank 60<SP>1</SP>, a relay 70 is energized to move on a switch 70 representing degrees of movement of table 10. After 10 degrees --of movement a pulse from bank 70<SP>11</SP> energizes a relay 80 of a switch bank 80 representing tens of degrees. When the wipers 88, 100, 109 are on the contacts respectively connected to the first of contact 120, 121, 122, circuits are completed to operate coincidence switches C1, C2, C3. This changes over switch CX to brake the motor and initiate measurement and printing. On completion of printing switch 190 is closed to energize relay 50 and move uniselector 50 to the next set of contacts. When all measurements are completed relay Q is energized to reverse motor 43 until table 10 resumes its starting position.
