Title: Machine for centrifugally casting iron pipes
IPC: B22D13/02
Filed: 1975-03-27
Abstract: 1492473 Centrifugal casting PONT-A-MOUSSON SA 27 March 1975 [3 April 1974] 12816/75 Heading B3F In a machine for centrifugally casting iron pipes on a horizontal axis, the casting mould 1 is maintained on sets of at least three coplanar rollers 7, the lower two rollers 8 being supporting rollers, and the upper pressing roller 12 being driven by a hydraulic motor 19. The upper roller 12 is mounted between the branches of a pivotal arm 13, pivotted on a fin 14 and the position of the roller 12 is controlled by a hydraulic jack 15, the piston 18 of which is attached to arm 13. An L-shaped lever 21, also pivotted to pin 14, has a projection 22 on the upper portion, the projection being capable of abutting a pin 24 on arm 13. The other end of lever 21 has a projection 25 and a ramp portion 26. When the mould 1 is in the casting position, it is supported on rollers 8, and upper rollers 12 bear down on it. Lever 21 is in the downward position, and ramp 26 lies below the upper level of rollers 8. To remove the mould from the machine, jacks 15 are actuated causing arm 13 to pivot about pin 14 and raise rollers 12 off the mould surface. The pin 24 then contacts projection 22 on lever 21 thus pivotting lever 21 and raising ramp 26 above the level of the rollers 8, thus the mould is removed from contact with the rollers. Simultaneously levers 27 pivotted on the end of arms 13 contact the casing 2 and due to their S-like shape, press against panel 5 in the casing, causing it to open and expose the mould which can then be rolled out of the machine on to rolls 33 in line with ramp 26. The rollers 8, 12 have diameters at least equal to the diameter of the moulds and, with an axial length equal to or greater than their diameter, consequently, the number of sets of rollers may be limited. The design of the machine is such that all the control and operating mechanisms is enclosed in fluid tight compartments.

Abstract: 837,911. Packages ; unpacking; boxes. CARR FASTENER CO. Ltd. March 21, 1957 [April 26, 1956], Classes 18 and 94(1). A package comprises a box, Fig. 1, provided with a slidable base 4 and formed with vertical partitions 2 defining compartments for the reception of stacks of valve holders or often electrical components which are required to be assembled on a panel, each stack resting on the base 4. The latter is formed with guide flanges 5 which engage the opposed side walls 1a of the box. Alternatively, the base may be slidable in transverse slots in the end walls 1b, in which case the flanges are omitted. The upper end of the box is provided with a cover 3 having a flange 3a which may be bent up to allow it to be withdrawn by sliding when it is desired to inspect the contents of the compartments. In use, the package is supported in a hopper 8, Fig. 3, having a base plate formed with apertures 8a which are aligned with the compartments a and are large enough to allow a stack of components to descend freely into a shoot 10 when the lower end of its compartment is uncovered by withdrawal of the base 4. An endless conveyer 11 is operated to position a panel 12 beneath the shoot so that a series of apertures 13 therein are aligned with terminals on the components, and an escapement mechanism associated with the shoot is then operated to allow the lowermost component to fall on to the panel so that its terminals enter the apertures. The operations are repeated with succeeding panels until the first stack of components is exhausted, and the hopper is then moved to position the next compartment over the shoot. If the panel is formed with a series of apertures for the reception of several components, it is moved in steps beneath the shoot. The box may be formed with two or more rows of compartments arranged side by side and a corresponding number of shoots provided to enable several components to be fed simultaneously to the panel. Specification 837,912 is referred to.

Title: Mechanical compensator for variable impedance remote indicating devices
IPC: G01F1/24
Filed: 1947-05-14
Abstract: 641,954. Electric indicating systems for pressure, flow, and temperature. FISCHER & PORTER CO. May 14, 1947, No. 13022. Convention date, Aug. 31, 1946. [Class 40 (i)] In a remote indicating device wherein a pair of transmitter coils and a pair of receiver coils are connected in an A.C. bridge, armatures movable by a variable condition respectively engage one transmitter coil and disengage the other, and armatures operating an indicator are correspondingly moved by the receiver coils to respectively engage one such coil and disengage the other, a weight is operatively connected to the receiver armature structure to exert a force thereupon tending to return the structure to its mid position against the action of the receiver coils when the transmitter armature structure is deflected from its mid-position, to compensate errors due to supply voltage variations. In the Figure a variable impedance remote transmission device of the kind described in Specification 610,708 has an elongated transmitter armature 26, axially movable by a vertically disposed flow meter float within a pair of transmitter coils 27, 28 which are energized from an A.C. source and bridge connected with a pair of laterally disposed receiver coils 36, 37 having movable armatures 40, 41 suspended from a pivoted beam 44 carrying an indicator. Variations in fluid flow displace the transmitter armature from a symmetrical position within the coils and correspondingly vary the fields of the receiver coils to move the armatures respectively upwards and downwards, thus tilting the beam to give a remote indication of the change. Errors due to the increasing attraction of the receiver armatures as they approach the coil centres and to changes in the supply voltage are compensated by an adjustable pendulum 9 fixed at right angles to the beam centre. Other mechanical compensating means such as a loaded cam roller may be employed, and the device may be applied to asymmetrical transmitter and receiver systems of the kind described in Specification 279,977, [Class 40 (i)]. The system may be responsive to pressure and temperature variations.
