Title: Determination of Fibre Characteristics in Paper Making
IPC: G01N33/34
Filed: 1966-10-06
Abstract: 1,154,350. Electro-physical measurements determining fibre size. BELOIT CORP. Oct. 6, 1966 [Oct.22, 1965], No.44756/66. Heading G1N. [Also in Division G3] The invention relates to measuring the size of fibre particles in a paper-making process from the amplitude and duration of pulses derived by the "boulter" principle. The paper stock is continuously sampled and brought to a predetermined dilution and conductivity before passing through the measuring circuit. The system is illustrated by block-diagrams which are largely self-explanatory. Sample control Fig. 1 The sample flow is continuously monitored and controlled; the dilution-water-flow is monitored and controlled to a predetermined ratio with the sample; after heating to a controlled temperature, the conductivity is monitored to control the electrolyte added to the dilution-water to maintain a predetermined conductivity. Length of the fibre is determined from the duration of the pulse which is clipped to constant amplitude and integrated to produce a sawtooth with a maximum amplitude proportional to the pulse duration Fig. 2 (not shown). A resetable holding circuit for the sawtooth maximum amplitude is illustrated in Fig. 6 (not shown). Diameter of the fibres is determined from the pulse amplitude. Errors due to coincidence of two or more fibres is eliminated by holding the signal for a "threshold maximum fibre length" - any signal in excess of this inhibits gating of the holdcircuit, Fig. 3 (not shown). In addition held sample values could be compared with a predetermined maximum value and rejected if in excess of this. These circuits may be combined to provide fibre volume and consistency analyzing arrangements Figs.4, 5 (not shown).

Filed: 1966-10-06
Abstract: 1,103,848. Broaching. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 Oct., 1966 [9 Oct., 1965], No. 44768/66. Headings B3B and B3L. A machine for cutting chevron-pattern grooves 2, 2a in a tubular workpiece 13 comprises a reciprocatable table 6 to support the workpiece for free rotation, a cam 16 (17) for attachment to the workpiece, and a pin 22 (23) to engage the cam and mounted on a tool carriage 27 movable transversely of the table. The work is clamped in a sleeve 12 against a shoulder 14 by a screwed ring 15. The cams 16, 17 are clamped on the sleeve 12 by a nut 19 and may have one or several grooves. An adjustable slide 28 carries a tool bar 30 having two sets of cutters 32, 32a, secured by wedges 34, 34a, to cut right- and left-hand helically-shaped grooves. In operation, the slide 27 is moved by a piston 36 by an amount determined by a cam 39 and a stop 44a, thereby engaging the pin 23 in the groove 21. When the carriage 6 is traversed, each cutter 32 takes a helical cut. At the end of the traverse, the slide 27 is returned to engage the pin 22 with the groove 20 so that the cutters 32a can then take a cut. Axial extensions (52) at the ends of the grooves 20 direct the tools out of the cut. When all the grooves have been cut, an increment of movement is imparted to the cam 39 so that subsequent cuts are made to an increased depth. To enable the tool to be withdrawn, the slide 27 is locked in the intermediate position of Fig. 10 by directing fluid through ports 46 and 49. In a modification, only one cam 16 is provided. In a further modification, the slide (27), Fig. 11 (not shown), is moved vertically.

Abstract: 448,512. Electromagnetic relays. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.-(Allmanna Svenska Elektriska Aktiebolaget; Vasteras, Sweden) Dec. 8, 1934, No. 35335.. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 12, 1935.] [Class 38 (v)] [See also Groups XXXVIII and XXXIX] Signalling or control over power circuits is effected by superimposing a voltage of the same frequency as the supply but displaced in phase and modulated by voltage of a frequency or frequencies significant of the desired signal or control. This is, in effect, frequency modulation of the supply, and the receivers comprise relays responding directly to the modulating frequencies. The modulating frequencies may be below or above the supply frequency, but a frequency double that of the supply is not used. as the receivers have a natural tendency to respond to this frequency. A receiving relay comprises a fixed winding 44 tuned to the supply frequency by a parallel condenser 60 and connected to the supply in series with a moving coil 45 carried by a rod 46 suspended by leaf spring 47. The rod 46 also carries springs 50, 51 timed to modulating frequency by weights 48, 49, so that when the supply is modulated at that frequency the moving coil and associated springs respond and make contact with springs 52, 53. The relay tends to respond at a frequency double that of the supply since both winding 44 and coil 45 are traversed by current of that frequency and to minimize this effect, a weighted spring 59 tuned to this frequency is connected. to the moving coil. In a modification, Fig. 7 (not shown), the moving coil is separately connected to the supply by means of a transformer.

Abstract: 1315396 Cellulose-acetate-coated fertilizers IMMOBILIARE SETTE SRL 22 Sept 1970 [29 Sept 1969 26 Nov 1969] 45026/70 Heading C1B A fertilizer with a matrix in granular form, e.g. a matrix of polystyrene or pumice granules, is coated with a film of cellulose acetate which is capable of being decomposed on contact with the soil owing to autogenous physical and biochemical reactions, so as to perform a progressive fertilization of the soil. In particular, the trace element boron may be supplied by this method, e.g. by applying solutions of sodium tetraborate (Na 2 B 4 O 7 .10H 2 O) to the matrix or by grinding boron-containing glass to a powder, preferably of grain size 10 to 100 mÁ, to provide the matrix. A process for the production of such fertilizers comprises dipping grains of broken or ground matrix materials of a size about 3 mm. into a solution containing various fertilizer substances, e.g. substances which contain nitrogen, phosporus, potassium, trace elements, phyto-hormones and/or fungicides or weed killers. Waste waters may be used provided these contain sufficient materials of fertilizing value. The matrix grains impregnated with fertilizer substances are dried at a temperature such as to avoid the decomposition of organic substances present in them, e.g. phytohormones. The film material may then be sprayed on to the grains. The grains may be coloured by impregnating the fertilizer solutions with various pigments so that different fertilizers may be recognized.
