Convention dates, July 30, 1932 and Nov. 25, 1932. [Classes 83 (ii) and 83 (iii)] [See also Groups VIII and XIII] A perforated suction press-roll &c., for paper-making machines comprises a shell 110, Fig. 6, with a covering 111 of rubber the outer part 111<a> being softer than that 111<b> next to the shell. The rubber is secured in annular grooves or threads, and longitudinal dovetail slots having rounded inner corners. The shell, which is seamless and of bronze or gunmetal, is drilled to have helically disposed holes in a gang drilling machine the end hole 122, Fig. 7 of a row being broached triangular or square for identification. The shell is removed from the drilling machine, finished to size and shape, the rubber applied and cured, and the shell replaced in the drilling machine. The identification hole is then extended from the inside through the rubber and used for locating the shell in the same position with respect to the indexing mechanism as it originally had. Holes of smaller diameter than those in the metal shell are then drilled in the rubber leaving small sleeves and slugs as shown in Fig. 11, which are pushed out by rods placed in the drill chucks and fed in without rotating. In action, Fig. 6, the press pressure is sufficient to close the holes at the nip, thus preventing the felt being distorted thereinto. Specification 422,829 is referred to.

Title: Improvements in or relating to automatic electric switches with overload release
IPC: H01H71/46
Filed: 1953-07-24
Abstract: 735,603. Automatic circuit-breakers. SIEMENS-SCHUCKERTWERKE AKT.-GES. July 24, 1953 [July 30, 1952], No. 20620/53. Class 38 (5). An automatic circuit breaker can be manually opened and closed by a slidable hand operating member which is coupled with a pawl slider carrying two pawls, one of which can lock a contact-operating slider in closed position and is controlled by a releasing slider, whilst the other pawl engages a fixed abutment in the closed position and is controlled by the contactoperating slider. Fixed contacts 1, 2 are arranged to be bridged by a movable contact 3 on a carrier 4 which is biased upwards by a spring 6. The contacts are held closed by the contact-operating slider 24 which has an arm 26 which is engaged by the first mentioned pawl 19. The latter is pivoted on a slider 18 together with a pawl 20 and has a part 22 engaging a recess 23 in the hand operating member 16 so as to couple this member with the pawl slider. The pawl 20 has a part 20<SP>1</SP> engaging the fixed abutment shown at 33 and each pawl has an arm 1911, 20<SP>11</SP> respectively engaging apertures 30, 27 in the releasing slider 25 and the slider 24. The arms 19<SP>11</SP>, 20<SP>11</SP> are urged against the edges of the apertures by springs 32, and the slider 25 is normally held in the Fig. 1 position by a bimetal strip 9 having a heater and in series with the contacts. When bimetal 9 deflects, the slider 25 is released and is moved down by a spring 29 so that a sloping part 31 of aperture 30 forces the pawl 19 clockwise to release the arm 26 and slider 24 to open the contacts. The upward movement of slider 24 causes a sloping part 28 of its aperture 27 to tilt pawl 20 counterclockwise to disengage part 20<SP>1</SP> from the abutment 33, so as to allow the spring 29 to raise the member 16 into an intermediate, indicating, position, Fig. 2 which is determined by the arm 19<SP>11</SP> abutting the upper end of aperture 30. The contacts will thus still open even if the member 16 is held down by hand (Fig. 3, not shown). Downward movement of slider 25 also allows contacts 12, 13 to close an indicating circuit. To reclose the breaker, the member 16 is pulled out from the Fig. 2 position, the arm 19<SP>11</SP> of the pawl 19 thereby raising the slider 25 which is relatched by the bimetal strip 9. Subsequent depression of the member 16 then causes arm 19<SP>1</SP> to engage and depress slider 24 to close the contacts. The contacts may be opened manually by pulling the member 16 out, the movement of arm 19<SP>11</SP> along aperture 30 releasing the slider 24 and opening the contacts. The parts are arranged in a slender rectangular casing having recesses and projections to guide the parts.

Title: Improvements in the process for preparing porous plates from cement and fibrous material on board-making machines
IPC: B28B1/52
Filed: 1937-07-30
Abstract: Porous fibre-cement plates are made on a board-making machine, by sieving or blowing a gas-producing agent such as aluminium or calcium carbide on to the fibre cement composition while it is on the felt band conveying it from the hollander to a cylinder, on which it is wrapped until a sufficient thickness has been applied, whereupon the layer is removed from the cylinder, dipped in water, and dried on shelves preferably adjustable to determine the amount of expansion. The gas-producing agent may be applied to the material while it is being rolled on to the forming cylinder.  By running the first and last layers on to the cylinder without the application of any gas-producing agent, plates are obtained having compact surfaces and a porous interior.
