Title: Improvements in and relating to typographical slug casting machines
IPC: B41B11/72
Filed: 1936-05-22
Abstract: 475,536. Type-bar-making machines. CLEMO, F. A. (Mergenthaler Linotype Co.) May 22, 1936, No. 14581. [Class 100 (iii)] Ejecting type-bars.-In machines of the kind described in Specification 396,045, and in which a buffer-plate is provided for supporting the slugs during ejection, the shoot leading to the galley is provided with relatively movable side-walls, which are automatically adjusted upon the ejection of a slug, in order to adapt them to various forms and sizes of slug, e.g. slugs of T- or L-shape in cross-section. The curved shoot E, Fig. 2, comprises a fixed base portion E<1> having the left-hand wall E<2>, Figs. 10 and 11, integral with it and formed at the upper edge with a flange E<3>. The movable right-hand wall E<5> also has a flange E<6> on its upper edge, and is mounted on a slide H, Fig. 5, which is normally held in its leftmost position by a spring. The buffer-plate K, which has secured to it a padding-strip K<2> to prevent damage to the face of the slug, is carried by a sliding member K<3>, and is urged towards the mould by a spring. The buffer-plate is normally held away from the mould by an eccentric K<8>, which is forced against the slide K<3> by a spring K<10> acting through an arm K<9>. During the descent of the first elevator A, a cam A<1> thereon acts through a lever L to move the slide H to the right. A pin H<6> on the slide thereupon acts through the arm K<9> to turn the eccentric K<8> and release the buffer-plate, which is moved towards the mould by its spring. After the elevator cam has passed out of action, the slide H carrying the movable wall of the shoot is still held to the right by the buffer-plate, which intercepts a plate H<5> on the slide. As the buffer-plate is pushed back by the ejected slug, the slide H is released, and the right-hand wall of the shoot moves towards the slug. In the case of T- or L-shaped slugs, one or. both of the flanges E<3>, E<6> on the shoot walls pass beneath the overhanging part of the slug, as shown in Fig. 11. The movement of the movable shoot wall is limited, according to the shape and size of slug being cast, by a plate b on the mould, which intercepts a pin H<7> on the slide H. The movement of the slide releases the arm K<9>, so that the eccentric K<8> locks the buffer-plate in its forward position. A spring pin M, which is pushed in by the elevator cam A<1>, enters a recess in the slide K<3>, so that, if the parts are not properly set, and the pin is obstructed, the elevator is arrested and the machine is stopped by the vice automatic stop.

Filed: 1953-05-28
Abstract: 783,172. Hydraulic machines. PULTRA, Ltd. April 29, 1954 [May 28, 1953], No. 14835/53. Class 69 (2). An hydraulically actuated valve reverses the direction of motion of a piston connected to a machine tool table at each end of the stroke of the piston upon the pressure in the supply conduit exceeding that in the return conduit by a - predetermined amount. A variable delivery pump 18 delivers liquid to a cylinder 13 through a conduit 15 and a reversing valve 17. In the position shown liquid is delivered to the end 20 of the cylinder, liquid from the end 19 passing to a reservoir through a conduit 22 and an unloading valve 23. A differential valve 29 is disposed between conduits 15, 22 and while the machine tool table- 10 is in motion the back pressure in conduit 22 is sufficient to keep the valve 29 in its right-hand position. When the table reaches a stop 36 the pressure in conduit 15 increases until valve 29 is moved to the left and liquid passes through conduits 28, 30 to move the reversing valve 17 to the left. The end 20 of the cylinder is thus put into communication with conduit 22 and end 19 with conduit 15, and the piston 27 of a pilot valve 26 is moved to the right. The pressure in conduit 15 falls to its operating valve and the differential valve returns to its initial position. When the valve 29 is actuated on the table contacting a stop 37 liquid is directed through the pilot valve 26 to move the reversing valve to the right.

IPC: B63C7/22
Filed: 1920-06-01
Abstract: 172,341. Dicker, S. G. S., (Ryan, A. H.). June 1, 1920. Electromagnets.-In an electromagnet for attaching buoys &c. to sunken or other vessels and encased in an open-faced casing having a flexible gasket around its edge, the casing is provided with a closure to exclude water and with means for withdrawing any water which may enter. The electromagnet 2 is secured to a block 6 of insulating material, by bolts 4 which may form the terminals, and enclosed in an open-faced casing 7, preferably of non-conducting material such as rubber, which is provided with a flexible gasket 23 round its edge. Rings 11 and 13 serve to attach cables for lowering the magnet and for the connection of buoys &c. To exclude water from the casing while being lowered, a closure is provided which may consist of a spring roller blind 14 operated by cords 18 and locked in position by a ratchet and pawl 19 on the roller 16. After the device has been pressed against the ship's side, the ratchet is released. Any water in the easing is withdrawn into a chamber 24 through a non-return valve 27 by means of a pump 28 operated to exhaust air from the chamber 24, or an electric heater may be used to heat the air, which will thus be expanded inducing a partial vacuum on cooling. The suction in the casing 7 causes the gasket 23 to make water-tight contact with the ship's side, and effective functioning of the magnet is ensured by the exclusion of water.

Filed: 1951-06-26
Abstract: 722,418. Counting particles. COULTER, W. H. June 26,1951, No. 15166/51. Class 37. Apparatus for studying, e.g. counting, particles suspended in a liquid which has an electrical conductivity different from that of the particles comprises means for providing an electrical conducting path of the same order of dimensions as the particles and means for detecting changes in conductivity as the particles pass through the path. In Fig. 5, elements 42, 44 are placed on one side of a narrow tube through which the fluid suspension flows, and the change in resistance as a particle 46 passes through is used for counting by any known method. In Fig. 6, electrodes 68, 67 are connected to a detecting device, and the resistance between them varies whenever a particle passes through the small aperture 65. In Fig. 8, a pointed electrode 87 co-operates with a plate electrode 82, and is rotated by motor 90; whenever the pointed electrode 87 comes near a particle an indication is given on meter 84. The pulse given by a particle may assume different shapes; thus in Fig. 13, the electrodes define a horn-shaped path, and the pulse is as shown at 151, while in Fig. 12, the electrodes define a uniformly parallel path to give a long pulse 143 which may be differentiated to provide sharp pulses 146, 147. In Fig. 7 a circuit is shown for averaging the pulses; the pulses are applied to valve 166 to charge condenser 178 through diode 177, the condenser discharging through resistance 183 so that it attains a charge proportional to the rate of impulsing. Where the particles consist of two kinds having different resistance, the amplitude of the pulses permits one to be distinguished from the other. Where they are of the same kind but differing in size, the amplitude of the pulses is an indication of relative size. The invention is applicable to counting the corpuscles in a sufficiently diluted sample of blood.
