Title: Visible recorder apparatus
IPC: G04G99/00
Filed: 1972-08-09
Abstract: 1396172 Recording apparatus HONEYWELL Inc 9 Aug 1972 [31 Aug 1971] 37058/72 Heading G1J [Also in Division H4] Time calibration lines defining a time scale having any of a number of different periodicities (line spacing) commensurate with the frequency range of signals recorded on a light sensitive medium have code marks associated therewith indicative of such periodicity. In Fig. 1, data signals supplied to one or more input channels 14, are supplied via respective amplifiers 16 to respective comparators 18 in which they are compared with the sawtooth output from a scanning generator 6 to produce, on amplitude equality, output signals which operate respective one-shot monostable multi-vibrators 20 the outputs from which are supplied via OR gate 22 and unblanking amplifier 24 to unblank the beam of a display cathode-ray tube 22 as it is scanned in a single horizontal line by the sawtooth from generator 6. A fibre optics 10 transmits the light trace to a light sensitive recording member 12 (preferably of the direct print out type) which moves vertically at a predetermined speed so that the input data signals are recorded as vertical traces as shown in Fig. 3 which also shows the (horizontal) time calibration lines together with, as an example, code marks indicative of, in this case, (see Fig. 4) a periodicity of 10<SP>4</SP> m.s. (=10Hz). Fig. 2 which shows the manner in which the calibration lines and code marks are produced, employs two J, K type flip-flops 34, 36, the J input to 34 being derived from a timing oscillator 40 via a variable frequency divider 42 controlled by adjusting means 46, the K input to 34 being derived via inverter 44 and both flip-flops being clocked by line retrace pulses 32 from scanning generator 6 the arrangement operating to produce via AND gate 38 a beam unblanking pulse fed to OR gate 22 which unblanks the beam for the duration of a complete horizontal trace at intervals determined by the adjusting means 46. The code marks are produced by supplying the line retrace pulses 32, selectively, via switches 52 controlled by the adjusting means 46, to one-shot circuits 54, providing the delays indicated, the outputs being differentiated by means 56, 58 and supplied via OR gate 60 as one input to AND gate 62 which received, as second input, the output of AND gate 38 after division by 10 in divider 64 (since the code marks are displayed only on every tenth line) and via a one-shot delay circuit 66 which holds AND 62 in the enabled state to allow sufficient code pulses to pass to produce code marks of reasonable length.

Abstract: 1,072,031. Injection-blow moulding. E. I. VALYI. Sept. 10, 1964 [Sept. 10, 1963; Nov. 27, 1963; March 18, 1964], No. 37097/64. Heading B4A. In an injection-blow moulding apparatus the blowing core or mandrel is sequentially located in a parison mould, moved axially to a blow mould with the parison, and withdrawn axially from the moulded article into a conditioning chamber where it is treated with a cooling or parting fluid, the moulded article being maintained under fluid pressure while in the blow mould after retraction of the core. In the parison mould 11 the mandrel 13 initially rests on the bottom of the mould cavity the top of which is defined by neck mould parts 52, 53. The plastics material is injected by a nozzle 20 and when the length of the parison has been formed the injection pressure causes upward movement of the mandrel and of a piston 42 which engages a pin 48 to actuate a switch 49 which de-energizes a solenoid 39 to actuate a cut-off valve 31 in the supply to the nozzle 20. The parison mould 11 is opened and the neck mould, mandrel and parison are elevated to a position within the blow mould 80, 81 which closes. Fluid under pressure is supplied to the mandrel to effect blowing after which the mandrel is withdrawn upwardly from the moulded article into a conditioning chamber comprising telescoped members 60, 70 and the surface of the mandrel receives a conditioning fluid such as cooling air or a parting agent, or a lining for the article. Air under pressure continues to be supplied to the article in the mould via port 87. The neck mould is then opened and the blow mould moved transversely out of the path of the mandrel as it returns to the parison mould where injection begins while the moulded article is removed from the blow mould by an inflatable finger.

Title: Improved means for delivering granulous material from hoppers and the like
IPC: B65G47/00
Filed: 1938-12-28
Abstract: 523,212. Delivering material from hoppers. NICOLAS, J. H., and GOUSSEAU, F. X. A. E. L. Dec. 28, 1938, No. 37672. Convention date, Dec. 29, 1937. [Class 78 (i)] A number of orifices 15, Fig. 5, in the bottom of a main hopper are opened and closed by the sliding movement of obturator plates 23 which are mounted on a common wheeled carriage movable between stops 30, 31 by an anchor member 44 operated by a pivoted bridge 39, carrying the delivery hopper 32 trunnioned at 35a out of line with the bridge pivots 40. When the hopper 32 fills faster than it can discharge through the holes 54 in the outlet pipe, the weight eventually tips the beam into the position shown in Fig. 5 against the action of the springs 48a, 49a and so causes the fluke 45a of the anchor to close the orifices 15. After the initial tilt a ball 42 rolls to the lower end of the bridge to increase the preponderance of weight and effect a quick action of the carriage. As the hopper 32 continues to discharge after the orifices 15 are closed, the springs 48a, 49a and the counterweight 57 eventually restore the bridge to a position beyond the horizontal, and the ball then rolls to the other end to complete the movement and re-open the orifices. In a modification, the anchor member is replaced by flexible connections between each end of the bridge and the carriage. Details in the construction of the hoppers: The hopper 32 is fitted with rollers 55 so that it can slide on the outlet pipe 33 and is also fitted with brush sealing- means 56. The main hopper is faced with tongued and grooved boards 1, Fig. 1, nailed to posts 2 supported in channel-irons 3. These channel-irons are bolted to a lower framework comprising wooden beams encased in channelirons and carrying feet 6. The orifices 15 are formed at the base of inverted pyramidal recesses formed by cross-girders p of angle-iron flanged by inclined metal sheet 12, 12a and by wooden filling-pieces 14 at right angles to the cross girders. The obturators are spaced from the openings 15 by an amount greater than the size of the largest material handled (for example, wheat) so that they cannot crush any material in closing. They are also formed with slightly up-turned edges to prevent delivery of material when they are in the closed position.

Abstract: Building units, e.g. bricks tiles, blocks slabs, floors &c. are prepared by casting in a mould and allowing to set a composition prepared by admixing reactive magnesia, at least 75% of which passes a 100 B.S.S. sieve, with at least one of a water-soluble chloride or sulphate (not magnesium) or sulphuric acid, and with a fibrous material and water.  The sulphate may be of Fe, Al, Cu, Zn, Na, K, NH4, or an alum and preferably reacts with magnesium hydroxide to produce a substantially water-insoluble oxide or hydroxide. Magnesium chloride, if used, may comprise up to 96,5% of the composition may include magnesium nitrate besides the chloride.  The fibrous strengthening material e.g. wood wool of flour, timber, cane, asbestos, may be impregnated with an aqueous solution of the chloride, sulphate or sulphuric acid and excess of the latter removed before mixing with the reactive magnesia, e.g. magnesite of dolomite calcined at 750 DEG C. to 850 DEG C.  Suitable fillers which may be incorporated include sand, quartz, marble fragments, granite, pulverised chert, diatomaceous earth, calcium carbonate, burnt clay, coke breeze, cinders, ashes, powdered pumice, kaolin, talc, barytes, glass, plaster, powdered slag or metal mineral ores, or pigments, the preferred particle size of these aggregates being greater than 100 B.S.S. mesh but smaller than 8 B.S.S. mesh.  The composition can include colouring matter or a metallic finish can be imparted to the slab by giving it a wash with a solution of a metallic salt which reacts with a metal salt already included in the composition; the resultant metallic film may be thickened by electro deposition and lacquered to resist oxidation.  By substitution of 7 1/2 to 20% of the magnesium chloride solution with a 7 1/2 to 15% alcoholic shellac solution a glazed finish may be obtained.
