Filed: 1972-09-26
Abstract: 1408205 Measuring the width of lines of typewritten print KARA-KOUNT Inc 26 Sept 1972 [28 Sept 1971] 44305/72 Heading G4H Apparatus 10 for measuring the width of a line of typewritten print comprises pulse sources 42-52 which provide coded signals representing each character selected from keys 16, a group of memories 68, a timing circuit 60 and a counter 86. The apparatus is used with a conventional electric typewriter 12 and includes twelve type style selection switches 20 as well as twelve type height selection switches 22. When a character key 16 is depressed a signal generator 66 supplies a signal to the timing circuit 60 which enables a selected one of six read-only memory stores in the group 68, each memory storing the character width data for a different one of six type styles. The memory store selected is determined by manual actuation of two of the switches 20 and at the end of a period of time determined by the circuit 60 the selected memory supplies a six bit output signal representing the selected character width on a line 146 to the counter 86. Clock pulses from a source 174 are fed via a divider 210 and a gating circuit 120 to the counter, the division ratio of the pulses being determined by the selected one of the type height switches 22. When the number of pulses supplied to the counter 86 corresponds to the signal supplied on the line 146, the counter provides a stop signal on a line 150 to the gating circuit. Clock pulses are also fed to a counter 122 simultaneously with the supply to the counter 86 so that the number of pulses fed to the counter 122 is a selected multiple of the pulses received by the counter 86. A numerical display 18 provides a digital indication of the total width of a line of print. The counter 122 and the display 18 are reset to zero at the end of each line by a carriage return pulse generator 62. Function switches 26 are provided including OFF, ADD, HOLD and SUBTRACT switches to enable respectively operation of the typewriter without operation of the apparatus 10, the addition of each character width in the line, holding of the existing total width despite further character key actuation, and subtraction of the width of an incorrect character. In the event of the selection of a character that is not suitable for the selected type style, the memory group 68 provides a signal on a lead 124 to an alarm circuit 100. Switches 34, 36, 38, 40 enable respectively a flashing light alarm, a low, medium or high audible alarm or a combination of these effects to be selected.

Title: Improvements in or relating to sorting fibrous material
Inventor: AYERST RONALD PERCY
IPC: B07B7/08
Filed: 1966-10-04
Abstract: 1,220,214. Centrifugal separation. NATIONAL RESEARCH DEVELOPMENT CORP. 4 Jan., 1968 [4 Oct., 1966], No. 44319/ 66. Heading B2P. Single-crystal, whisker-like fibres having a diameter of not more than 5 microns and a length/diameter ratio of between 20 and 1,000 are separated from coarer fibres of substantially the same density and/or from contaminants of non-filamental shape but of substantially the same density and having an equivalent diameter intermediate between the length and diameter of the whisker-like fibres by feeding a liquid dispersion of the whisker-like fibres and coarser fibres and/or contaminants into the tangential inlet of a hydrocyclone and collecting a dispersion of whisker-like fibres discharged from the overflow outlet of the hydrocyclone. The whisker-like fibres may be fibres of silicon nitride, silicon carbide or aluminium oxide of 1-2 microns in diameter and 100 microns long contaminated with grit, or asbestos fibres of 1-5 microns in diameter and 100-1,000 microns long intermixed with coarser asbestos fibres and grit. The liquid dispersion is contained in a vessel 3 which is connected via a control valve 4 and a pump 5 to a primary hydrocyclone 1 having an under flow pot 10 of translucent material across which light is projected to a photo-electric device 11 associated with a control unit 12 for a valve 13 in a discharge pipe 14. A connecting pipe 6 leads from the vessel 3 via a control valve 7 and a pump 8 to a secondary hydrocyclone. At the start of an operation, the valve 4 is opened and the valves 7 and 13 closed. A prepared volume of the dispersion is continuously pumped from the vessel 3 through the hydrocyclone 1 and back to the vessel whereby the coarse fibres and contaminants accumulate in the underflow pot 10 of the hydrocyclone. When due to this accumulation the light which reaches the device 11 is reduced to a predetermined value the device 11 sends a signal to the control unit 12 which causes the valve 13 to open for a short period of time to discharge the contents of the pot 10 through the pipe 14. The time intervals between successive discharges of the pot 10 is an indication of the concentration of unwanted material remaining in the circulating dispersion and when the intervals exceed a preassessed time period the circulation of -the dispersion is stopped either by an operator or by an automatic timing control system (not shown) which cuts off the power supply to the pump 5. A device which senses the dielectric constant of the liquid content of the underflow pot may be used instead of the photo-electric device 11. Further sorting of the whisker-like fibres may be effected by opening the valve 7 and closing the valve 4 and pumping the liquid dispersion from the vessel 3 through the hydrocyclone 2 from which the very fine whiskerlike fibres are discharged through the overflow outlet 22.

Abstract: 1,039,008. Making envelopes. R. WINKLER, and K. DUNNEBIER. Nov. 9, 1964 [Nov. 15, 1963], No. 45520/64. Heading B5D. In an apparatus for making envelopes (Fig. I, not shown) blanks 10 with the side flaps prescored pass individually through rollers 1, 4, where knives 2, 3 produce score lines 12, 12<SP>1</SP> for the bottom and top flaps, and are then directed by suction rollers 5, 7 into folding ploughs 14, where the side flaps are folded down, and then to a roller 15 on which they are gripped by rows of suction holes 16, 17 adjacent the bottom and top score lines. Gum is applied to the side flaps by means of segments 23 attached to a drum 22, splattering of gum on to undesired areas being prevented by plates 27. On passing under a roller 30 vacuum is released from the suction holes 17 and a forward end 13 of the blank is carried by suction holes 31 on the roller 30 into the position in Fig. 6 (not shown). Suction at holes 31 is then released and the blank, held by the suction holes 16 acting alongside the score line 12, is carried under the roller 33 to fold the bottom flap against the glued side flaps. Suction is then removed from the holes 16 and the envelope is carried away by suction provided through holes 35 of a roller 34. The roller 15 (Figs. 2, 3 and 4, not shown) comprises two rings 41, 42 attached to a shaft 47 by spokes 43, 44 and connected to each other by four arms 48 and four arms 49. Each arm 48 carries a suction channel 50 and a row of suction holes 16, and each arm 49 a suction channel 58 and a row of suction holes 17, the channels being connected by flexible tubes 54, 62 to a vacuum source. The arms 49 are adjustable with respect to the arms 48 for varying the distance between the rows of suction holes 16, 17 to accommodate different size envelopes. The rim (Fig. 2) is formed by a series of segments having the shape of circular arcs and being fastened to strips 55 which form part of the channels 50 and carry the suction holes 16: segments 65, 66 provide openings along which the position of the suction holes 17 can be adjusted, while segments 68 have grooves 69 in alignment with the gumming segments 23 so that smearing of the rim with gum in the absence of a blank is avoided.

Filed: 1964-11-16
Abstract: Wet process H3PO4 is purified by evaporating it in a submerged combustion or analogous evaporator to 80% by weight P2O5 content, thereby forming insoluble compounds of the impurities, diluting the conc. acid to a filterable viscosity and removing the solids therefrom. The purified acid may be reconcentrated in a second evaporator.  The solids, which may be separated by e.g. filtration or decantation, may be washed with H2O which is then added to the purified acid.  The solids, claimed per se, comprise poly- and meta-phosphates of Al and Fe. These solids may be digested with HCl to forming the chlorides and H3PO4 values, the latter being removed by solvent extraction or ion exclusion, or the solids may be fused with KCl to give KPO3.  The gaseous effluent from the evaporators may be condensed, e.g. as described in Specification 1,081,891, and the H3PO4 recovered.  Organic impurities may be removed from the impure acid by adding small mounts of an oxidant, e.g. HNO3, KNO3, before concentration.
