Title: Improved method of mechanically processing wood-pulp for paper-making
IPC: D21B1/12
Filed: 1947-08-06
Abstract: 660,570. Treating paper pulp. PRICE BROS. & CO., Ltd. Aug. 6, 1947 [Nov. 25, 1944], No. 21343/47. Class 96. Individual fibres in paper pulp are bent or curled and shives are broken up by forming the aqueous pulp into small nodules, in which the fibres are randomly intertwined, and compressing and rolling the nodules between two rough surfaces moving relative to each other to aggregate them into groups which are themselves rolled, under pressure, in changing directions which may vary continuously. The pulp may be rolled at right angles to the direction in which it is pressed and the surfaces may be parallel and plane. The paths along which the pulp rolls may be curved. One surface 3 may move relative to the other 4 so that all points in the former execute separate closed paths, e.g. equal circles 6. The surfaces may be moved periodically to and fro. The clearance between the surfaces may be “ to # inch, the pressure between them from 1 to 20 lb. sq. inch and their relative velocities from 50 to 300 ft. min. A machine (not shown) for treating nodulated or unnodulated pulp has two horizontal metal plates with flat opposed knurled surfaces. The upper plate is moved cyclically to and from the lower plate and is simultaneously reciprocated across and parallel to the lower plate, downward motion occurring near the start of a cross stroke and upward motion taking place at the start of the return cross stroke. Groups of nodules may be reoriented by jets of compressed air. The lower plate may be gyrated horizontally. Pulp may be dewatered to a consistency of 2 to 60 per cent before treatment. To facilitate the breaking-up of shives, the pulp may be heated and bond-softening chemicals may be added. Bleaching, de-sizing and de-inking agents may be added. It is stated that the freeness of the pulp is not impaired by the treatment and that the resulting paper has a high wet stretch. Specification 650,733 is referred to. The Specification as open to inspection under Sect. 91 also comprises apparatus for prenodulating the pulp and apparatus for treating the pulp before nodulation. This subjectmatter does not appear in the Specification as accepted.

Patent GB-853433-A (GB)
Title: Improvements in or relating to apparatus and method for controlling the thickness ofa workpiece
IPC: G05B19/06
Filed: 1958-07-04
Abstract: 853,433. Rolling. WESTINGHOUSE ELECTRIC CORPORATION. July 4, 1958 [July 16, 1957], No. 21466/58. Drawings to Specification. Class 83 (4). [Also in Group XXXV] In a method of controlling the thickness of moving material being rolled, a first correction is made proportional to a first detected thickness error and a second correction is made which is a function of the first correction, the first detected thickness error, and a second thickness error detected after the first correction. An electric control system (see Group XXXV) is described in which signals dependent on the error in thickness of material emerging from the rolls of a strip rolling mill are derived from a radiation gauge at intervals dependent on the speed of the mill. After one error signal has produced a first correction by causing adjustment of screwdown motors which set the roll spacing, it is stored together with a signal representing the first correction so that they may be used with the next error signal to compute the second correction. This two-stage method of correction is repeated at intervals. In a modification, the first thickness error signal is obtained from a strain gauge associated with the mill and the second correction signal is computed from a second thickness error signal obtained from the strain gauge, a signal representative of the first thickness error obtained from a radiation gauge located at an appropriate distance on the output side of the mill, and a signal representative of the first correction obtained from the position of a screw-down motor. Alternatively the two thickness error signals may be obtained from two radiation gauges located at different positions on the output side of the mill, the distance between them being adjustabe with strip speed. In another modification three signals, obtained as in the previous modification, are displayed on meters and, at an appropriate time indicated by a light flash initiated by the mill motor, computer potentiometers are set manually to positions corresponding to the meter readings so that the second correction of a screw-down motor is effected by the computer output.

IPC: G01N25/64
Filed: 1960-06-21
Abstract: 951,942. Measuring electrically. BRADFORD DYERS' ASSOCIATION Ltd. June 16,1961 [June 21, 1960], No. 21744/60. Heading G1N. The moisture content of a material is determined, for the purpose of controlling that content, by measuring the relative humidity of air in moisture equilibrium with the material by means of electrical wet and dry thermometers which give a single signal, and modifying the signal in accordance with the temperature by means of a second electrical dry thermometer. Applications are in the control of the moisture content of continuous lengths of textile materials, bales of cotton, wool, tobacco, hay and silage. Air is drawn from the vicinity of a continuous sample 1 of textile material after it leaves a drying apparatus (not shown) and passes over a dry thermistor 3 and a wet thermistor 4, kept moist by wick 5 dipping into water reservoir 6. Further dry thermistor 9 compensates for the temperature of the airstream. Thermistors 3, 4 are fed with two equal antiphase outputs from a balanced transformer and the resulting output is amplified and fed to a non-linear amplifier, whose gain is controlled by thermistor 9. The output is rectified and fed to a meter giving a relative humidity reading indicative of the moisture content of the material, and to a control unit which alters the speed and/or temperature of the drying apparatus. The percentage moisture content by weight may be calculated for a given material. Electric resistance thermometers or thermocouples may be used instead of thermistors.
