Abstract: 1,008,753. Board making. BELL MASCHINENFABRIC A. G. Dec. 11, 1961, No. 44323/61. Heading D2A. A method of severing and removing a fibrematerial coating 4 on the forming cylinder 1 of a pressed pulp load making machine consists in severing the coating along a groove 6 by means of one or more cutting element 7 which can also grip the coating after it has been severed to draw it off and place it on a conveyer belt 26. As shown, two gripping and cutting elements 7 are provided on piston rods 10, 10a and normally these elements lie beyond the ends of the cylinder 1, one each side. When sufficient thickness of coating is on the cylinder or after a predetermined number of revolutions thereof, the cutting and gripping elements are brought into line with a groove 6 in cylinder 1, moved inwardly to the centre of the cylinder to sever the coating and then the pivoted gripping elements 7c of the grippers are operated to grip the severed edge. The elements then move away from the cylinder to lay the board on conveyer 20. Further elements 8 which lag the elements 7 in an adjustable manner may be arranged to grasp the outer margins of the severed edge. To prevent damage to the coating the cylinder 1 is automatically slowed during severing and removal of the coating. The board is conveyed away by conveyer 26 to a non-driven conveyer (see Fig. 5 not shown) e.g. a series of adjacent bars and thereto the conveyer belt of a press or drier. Since thin board would buckle on the non-driven conveyor provision is made to incline conveyer 26 upwardly so that a thin board will be able to slide down the non- driven conveyer to the press or drier conveyer. In the form shown the cutting and gripping element are pneumatically controlled but electro-mechanical devices may alternatively be used.

Abstract: 871,680. Electric digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 31, 1959 [Dec. 31, 1958], No. 44362/59. Class 106 (1). Information is recorded on a magnetizable medium by producing relative movement between the medium and a plurality of magnetic fields, applying a first magnetic field to magnetize elemental areas of the medium in one direction, applying a second magnetic field to reverse the magnetization of the elemental areas, means being provided to remove the second field at times determined by the information to be recorded so that spaced elemental areas remain magnetized in said one direction. The numerous embodiments described have as a common feature a unipolar magnetic recording head which produces an effective magnetic field in the plane of the medium as shown in Fig. 1. The head may be a permanent magnet 13, Fig. 2, provided with a winding 14, or a permeable member having an energizing winding, or a wire which contacts the medium and through which current is passed, the circuit being completed through the medium to a brush contacting the opposite side. As shown in Fig. 2, the medium is premagnetized in direction 11 and is moved past head 13 whereupon the first part of the field of head 13 magnetizes the medium in direction 12, and the second part of the field reverses the magnetization to the original direction 11. By energizing winding 14 so that the field is reduced for a short period as the medium passes under the head, or by moving the head away from the medium, elemental areas 16 remain magnetized in direction 12. Alternatively, head 13 may be deflected electrostatically at right angles to the direction of motion of medium 11 so that small areas magnetized in direction 12 are not erased by the second part of the field.

The hour wheel 1 carries twelve circumferentially spaced magnets 11 which normally co-operate with aligned pieces 12 of soft iron in the wheel 6 to drive the latter. When the wheel 6 is rotated by means of a stem or other mechanism to set the hour hand 7, the wheel moves in angular steps owing to the forces between the magnets 11 and soft iron pieces 12. Rotation of the hour wheel 1 is avoided since the magnetic forces are insufficient to overcome the frictional mounting of cannon pinion 4 on its arbor 5. The wheels which are magnetically linked may alternatively be minute wheels, in which case the number of magnets is reduced in proportion to the ratio between the hour wheel 1 and minute wheel pinion 2. The soft iron pieces 12 may be replaced by further magnets, and one or both wheels may be made of a magnetizable material and magnetized to obtain the desired poles.
