Filed: 1975-10-28
Abstract: 1503709 Justifying lines of print INTERNATIONAL BUSINESS MACHINES CORP 28 Oct 1975 [17 Jan 1975] 44238/75 Heading G4H In justifying a line of print, the number of escapement units in the line is set into a register at the start of the line, a number of escapement units corresponding to the width of each character and a minimum width for each space is subtracted from the register to derive a residue, the number of spaces in the line is counted, multiplied by a number corresponding to the difference, in escapement units, between the desired maximum and minimum width of a space, and when the resulting product is equal to or greater than a predetermined number and the residue is equal to or less than the predetermined number, an indication is given, e.g. a bell, to alert the operator to look for a suitable line ending. Preferably the minimum and maximum space widths are 3 and 12 units, the multiplier being 9, and the predetermined number is 36. If the residue drops to or below zero the carrier is automatically backed up to the beginning of the last word. For justifying lines held in a buffer store, an automatic search for the next space is made, followed by insertion of a carrier return code.

Title: Solvent cleaning of spray nozzles
IPC: B05B15/02
Filed: 1973-09-20
Abstract: 1450170 Cleaning spray nozzles COMALCO PTY Ltd 20 Sept 1973 [22 Sept 1972] 44245/73 Heading B2F  . Apparatus for applying sealing compound to a workpiece, includes an intermittently operated ejection nozzle (52), Fig. 1, (not shown) and means for inhibiting build-up of sealing compound at the nozzle outlet, which comprises means to direct a stream of air towards the outlet of said nozzle from a suitable air. outlet 48, Fig. 3, and means to inject a solvent into said air stream at a point 50 upstream from said air outlet, said means to direct an air stream towards the outlet of nozzle (52) including a jet pipe 42 and.adjustable means to control the rate of solvent supply and to produce turbulence of the air at the nozzle outlet. The jet pipe has a small-diameter outlet 48 and a bend 46 of relatively large radius distant from said outlet, and said means to inject a solvent into said air stream comprises a hypodermic needle 40 which enters said jet pipe 42 on the outside of the bend 46 and is aligned substantially coaxially with said jet pipe between the bend and the outlet 48 of the jet pipe. Solvent, e.g. hexane is dispensed under air pressure applied to the surface of the solvent in a container 10, Fig. 4, means being provided to control the air pressure in the jet pipe and at the solvent surface to make the former pressure at least slightly less than the latter. This is done by precision regulators 24, 26 controlling branches 20, 22 of the air supply 18, the branches being fitted with pressure gauges 28, 30. Branch 20 passes to an air inlet 14 in the cap 12 of a solvent container 10, which also has a solvent outlet 16, while branch 22 is fed to air jet pipe 42 having a diameter of 0.5 cm tapering to 0.038 cm at 44. A tube 34, fitted with a filter 36, extends from the solvent outlet of cap 12 and is connected to a small bore tube 38 which has the hypodermic needle at its outlet, said needle entering jet pipe 42 at 50. Thus, the outlet of needle 40 is located at approximately the centre of the cross sectional area of jet pipe 42 and points in approximately the same direction as the air flow. The space between the needle 40 and the hole 50 is sealed by placing a short length of rubber or plastics tube around the pipe, through which the needle is passed. Nozzle (52), Fig. 1, (not shown) is supported in a fixed bracket (54) above a turntable (56) to which can end blanks (58) are fed for lining with sealine compound, e.g. a synthetic rubber, the ejection of the compound being controlled by e.g. valve gear (62). The distance between outlet 48 and nozzle (52) is sufficient to provide turbulence in the area of nozzle (52).

Title: Paper cleaning apparatus
IPC: B41F23/00
Filed: 1966-10-04
Abstract: 1,137,418. Cleaning apparatus. W. C. HERBERT. 4 Oct., 1966 [18 March, 1966], No. 44344/66. Heading B6C. A method for removing foreign particles from a moving sheet which may be subsequently printed, comprises directing a stream of ions at the sheet to neutralize electrostatic charges between the foreign matter and the sheet, then drawing the ionic stream through the bristles of a brush, the foreign matter being loosened by the brush and finally removed under vacuum. Fig. 1 illustrates an apparatus in which a continuous web of paper 10 is cleaned by a vacuum head 14 which extends transversely across the sheet or web and is connected by a flexible coupling 26 to an evacuator 28 and a collector bag 30. Fig. 2 contains details of the vacuum head 14 wherein a conducting housing and coverplate 38, which together with the rear wall 18 forms an open-ended transverse chamber 40, serves as one electrode of the ionizing unit; the central electrode 46 includes a plurality of transversely spaced pointed members 48 which emit high voltage charges ionizing the air between the members 48 and the housing 38, a potential difference being maintained by a high voltage source 50. A transverse brush 64 with bristles 62 is supported between rear wall 18 and intermediate wall 20; front wall 16 and intermediate wall 20 define a passage 22 which connects to the evacuator; hence the stream of ionized particles 80 are drawn along the sheet 10, through the bristles 62 and up the passage 22 (arrows 82 indicate this path). A second brush 72 with bristles 76 is preferably supported on front wall 16, air being dragged through this brush by the vacuum (arrows 84). Therefore the brushes 64 and 72 form limited air barriers which define the cleaning space therebetween, foreign matter being carried away through passage 22. Pressure adjusting means for adjusting the pressure applied to the brushes may also be incorporated (Fig. 3, not shown).

Title: Apparatus for extricaging ceramic castings from multiple piece moulds
IPC: B28B1/26
Filed: 1970-09-18
Abstract: 1310844 Slip casting MANSFIELD SANITARY Inc 18 Sept 1970 [13 Oct 1969] 44635/70 Heading B5A In a system for extricating a slip-cast ceramic article, e.g. a toilet pan, an umber of moulds 30 from a mould a, b, c and d are positioned on a table 59 in a carriage 45. Each mould is formed by side portions 32, 33, a base 31, and a core 34. After casting, the cores 34 which are supported on a beam 79, are raised by means of a lifting ring 110 and secured in an upper position by a latch 96. The table 59 is then moved across the carriage to an inversion mechanism 100. The mechanism 100 has tines 125 which locate in notches 128 in the mould portions 32, 33. The tines 125 extend radially from a roll bar 115, which can be moved vertically between guide plates 118, 119 by a hook 134, and secured in an upper position by a pivoted rest 135, to move the moulds clear of their base portions 31. The table 59 together with the base portions 31 can then be moved to the opposite side of the carriage. In the raised position the mould portions 32, 33 and the ceramic article can be inverted about the roll bar 115 by a mechanism (102) Fig. 10, not shown. The tines 125 are engaged by a hook (151) of a fluid actuated piston and cylinder (102) pivotally supported above the carriage at (154). Cylinder (102) rotates the tines 125 about the roll bar 115, and the centre of gravity of the mould and article is arranged so that they tip over on to an outrigger 175 located on a rail (198) Fig. 10, adjacent the carriage 45. A gripper (185), Fig. 11, not shown, suspended from a monorail (209) then picks up the moulds and articles, removes them from the tines 125 and transports them to a conveyer bat (255), Fig. 14, not shown, on a conveyer 270 at a receiving station 190. The gripper has tongs (228) actuated by a fluid piston and cylinder (238), and clamps (232) actuated by a piston and cylinder (234). Before disengaging the mould portions 32, 33 from the castings, the bat (255) is lifted by a piston and cylinder (261) Fig. 14, to assume the full weight of the articles. Thereafter the mould portions are disengaged from the articles by the piston and cylinder (238) and the articles are moved along the conveyer (270) to a receiving station.

Title: Improvements in and relating to data translation and printing apparatus
IPC: G06K15/10
Filed: 1960-12-30
Abstract: 968, 026. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 30, 1960 [Dec. 31, 1959], No. 44706/60. Heading G4H. In a record card interpreter, Fig. 1a, data read from plug-selected field of a card 100 is stored, by mechanically latching appropriate combinations of displaceable slides 109, and then readout into a core matrix 115 so as to control a wire printer 116 to print the data in the end column of the card from which it was read. Two stores "data trans A" and "data trans B" are used so that while data is being read into one from a card data is being read out of the other to the printer. Each data store comprises six vertical sliders 109 and one strap 106- see also Fig. 6-for each character, together with six horizontal bars 108 which are raised in appropriate combinations by cams 110 as a card is sensed. In operation, with the strap 106 in the position shown in Fig. 6, the bars 108 can be raised without affecting the slides 109. However, whenever a hole is sensed in a card an electro-static clutch 104 moves the strap to the right thereby interposing studs 107 between the bars 108 and the slides 109 so that the next bars raised also raise the corresponding slides. Those slides 109 which are raised are retained in their raised positions by releasable spring clips. For read-out purposes, each set of six slides co-operates with a printed circuit board Fig. 2 on the back of which Fig. 5 are a plurality of switches constituted by bent wire 155 and pins 159, 160 controlled by the slides. The printed circuit is such that for each combination of raised slides only one of 47 output terminals is connected to an input terminal.

Title: Recorder controlled fluid delivery system
Inventor: VALERIO FERNANDO DA SILVA
IPC: B67D7/08
Filed: 1967-10-02
Abstract: 1,207,845. Dispensing fluids. F. DA SILVA VALERIO. 2 Oct., 1967 [30 Sept., 1966], No. 44808/67. Heading A4T. A fluid delivery system from a delivery truck in which a ticket is printed with a gallonage reading at the beginning and end of delivery, has means permitting a limited movement of the truck for a short time which, if excessive, stops delivery and prints the ticket and means which stop and print if air enters the delivery pipe. With delivery valve 23, Fig. 2, closed and signal controlled valve 21 open, pump 16 circulates fluid from tanks 11 via 13, 19, 22. When valve 21 is closed pump pressure shifts a piston valve in actuator until pump pressure is applied to open valve 23 and deliver via totalising meter 24. If the ticket is wrongly inserted at 30, Fig. 1B, contacts 31, 32 remain closed and on closing manual delivery switch 34, Fig. 1A, a lamp 43 blinks via relays 37, 40. On correctly inserting the ticket to close contacts 32, 33, momentary closing of switch 34 energizes relay 36 through relay 44 and a switch system operated by cams 47-49 driven via the printing head from motor 45 energized from relay 36. Relay 44 closes to energize the solenoid valve 21 and lamp 60 for fluid delivery and advances a delivery counter 61 by one step. The final printing and stopping of delivery is produced on depressing switch button 62 acting via relays, interlocks and a time delay relay 65. A pendulum operated mercury inertia switch 71 is momentarily closed if the truck is moved and energizes relay 73 which becomes interlocked from relay 64 and feeds delay relay 74 which prevents stopping of delivery and printing for a predetermined time after which the relay closes. Any further truck motion stops flow and prints. Should a predetermined amount of air be entrained in the delivery pipe, a photo cell receiving light through the fluid energizes relay 96 and lamp 98 to close valve 23, and after a delay from relay 97, permanently stops delivery.
