Abstract: 1435226 Making casks from staves DCL COOPERAGE CO Ltd 26 July 1974 [2 Aug 1973] 36748/73 Heading B8D Apparatus for use in erecting cask shells from staves comprises a jig plate 7, an abutment ring 13 fixed to the jig plate, and support members 14 attached to the jig plate and supporting a temporary truss hoop 16 spaced above the jig plate in co-axial relationship with the abutment ring, the jig plate being supported so that it can be rotated about the axis of the ring or an axis parallel thereto. The apparatus enables a cooper standing at one position to assemble a plurality of staves in a general upright condition with the lower ends located by the jig plate, abutment ring, temporary truss hoop, and a lower truss hoop placed loosely on the jig plate about the abutment ring without having to move around the cask shell being created. The apparatus also includes a windlass comprising a cable loop 27, which can be stored in an inoperative condition on a stand 32, and a pair of horizontally-opposed pneumatic rams 28, which grip the ends of the cable loop and which are actuable, when the loop is positioned over the upper ends of the staves, to tighten the loop and draw in the staves. An upper truss loop may then be placed over the assembled staves. One of the support members 14 is hinged at 18 so that, on pivoting down of this member, the assembled shell may be removed. The temporary truss is taken off and re-used. Whilst the jig plate may be mounted on a roller carriage and turntable, or on roller bearings, so that it can be freely spun, as shown, the jig plate is supported on an air cushion 23 formed between it, a base-plate 1, and a P.T.F.E. skirt ring 9 and is free to rotate and move in a direction laterally to the line of action of the rams within the confines of a ring of nylon rollers 6. The lateral movability of the jig-plate ensures that the cask shell is subjected to only radial constrictive forces on tightening of the cable loop.

Title: Control method and apparatus for the repeated pouring of identical quantities of molten material from a ladle with a bottom discharge orifice
IPC: B22D39/04
Filed: 1976-09-10
Abstract: 1531835 Automatic control of metal pouring BROWN BOVERI & CIE AG 10 Sept 1976 [10 Sept 1975] 37598/76 Heading G3N [Also in Division B3]  A bottom discharge ladle has the rate of outflow into a mould controlled by the position of a plug 32 which is moved by a stepping motor 11 operated from a computer which processes signals of the weight of material in the ladle and the duration of the discharging operation. In order to obtain a uniform casting the rate of flow has to be controlled so that at the end of the casting time the mould is just full. Additionally the height of material in the ladle will affect the outflow rate so a strain gauge 5 monitors the weight of ladle 30. The computer responds to manually set values of duration and the like, and the output of strain gauge 5 to produce a number of pulses which operate stepping motor 11 to move plug 32 until a position monitor indicates to the computer that the required position is reached. An electromagnetic valve 16 is provided, which when de-energized, exhausts the air-pressure in chamber 38 and allows plug 32 to fall and stop the outflow of material. On restoration of power the stepping motor will be run to the closed position indicated by a limit switch ready for the next casting operation. The ladle shown is supported on strain gauge 5 and has a lid 33 which is supported from the plug bottom bearing 35 which also supports the top bearing 37 and the stepping motor 11 through frame 36. Hand wheels 47, 48 set the limits of travel of plug 32 and guide 40 prevents rotation of the plug. In operation the stepping motor drives gear 43 which rotates on screw 44 to raise or lower the plug. As the plug is raised the reservoir 38 is filled with air under pressure so that under failure conditions the air is exhausted and the plug drops to close orifice 31.

Title: Pervious metal fiber material and method of making the same
IPC: B22F3/00
Filed: 1961-10-27
Abstract: A porous metal compact such as a filter is made by gas plating a mass of randomly disposed organic carrier strands with a metal such as Fe, Ni or Cu followed by decomposition of the organic strands to leave the hollow metal jackets which are compressed to form a porous compact.  The organic strands may be natural fibres such as cotton or synthetic such as viscose and cellulosic fibres and the gas plating is effected either on the individual fibres or on a mat of the fibres by the thermal decomposition of the corresponding metal carbonyl. After the plating step which is effected in an inert gas such as CO2 or N2 the coated mat of fibres is heated to 1400-1500 DEG F. in the case of Ni on cellulose fibres, and after cooling, the remaining Ni jackets are pressed and sintered.  A woven metal cloth may also be sintered on to the malted metal jackets as a reinforcing means.

A "hybrid contactor" comprises an electromagnetic contactor B, P, a shunt thyristor Th1 connected across the contacts P, a second thyristor Th2 to discharge a blocking capacitor C through the thyristor Th1, and an arrangement for controlling the thyristors so as to prevent or minimize arcing at the contacts, this arrangement including a differentiating circuit A1 to derive a signal for triggering the thyristor Th1 from the leading edge of the voltage pulse arising across the contacts P when opened. This signal is applied through a monostable vibrator A2 and amplifier A3 to the control electrode G1 of the thyristor Th1 to cause the thyristor Th1 to conduct. The signal from A3 is also applied to a second differentiating circuit A4 which differentiates the trailing edge of the signal to produce an output, which through an inverter A5, a gate A6, and an amplifier A7 triggers the thyristor Th2 after a delay imposed by a resistance capacity circuit C4, R13 in the inverter A5. The thyristor Th2 conducts to permit the capacitor C to discharge through and block thyristor Th1. If however the opening of the contacts P was due to contact bounce, the control switch I for the coil B being closed, then an inverter A10 applies a blocking signal to the gate A6 to prevent the operation of the blocking circuit Th2, C, the thyristor Th1 ceasing to conduct when the contacts reclose. A differentiating circuit All, an amplifier A12 and a pulse transformer A13 control a third thyristor Th3, through which the capacitor C is charged. The supply for the transistors in the various circuit elements is provided by a capacitor Cl which is charged from the contactor coil supply through switch I and discharged by a thrystor Th4 which is triggered on at the end of an opening operation by the signal from amplifier A7.
