Abstract: A vacuum transfer conveyor apparatus is provided for 
transferring containers (52) from one elevation to another 
having a plenum wall (W) against which a transfer belt (60) 
traverses, which wall (W) is provided with a plurality of 
parallel longitudinal slots (92,98,198,112) which extend from 
larger pick-up openings (94) at the upstream end of the 
plenum wall to the downstream end. These slots

the seal between the edge of the container and the transfer 
belt. The transfer belt (60′) may be provided with a deform­
able foam (114) surface which provides an improved seal 
between the edge of each container (52 and the transfer belt

Title: Process and apparatus for making sponge iron, especially pig iron
IPC: C21B13/14
Filed: 1985-09-30
Abstract: A process for producing sponge iron from iron ore is described, which is reduced to sponge iron in a reduction shaft furnace by means of a hot reduction gas. For this purpose reduction gas at a temperature in the range 750 to 900 DEG  C. is introduced into shaft furnace (1) level with bustle plane (5) having been produced in a gasifier (2) then cooled and purified in a cyclone separator (12). Reduction gas is introduced below the bustle plane (5) at a temperature below that of the reduction gas introduced in the bustle plane and is preferably introduced into the shaft furnace (1) between 650 DEG  and 750 DEG C. Increased carburization of the sponge iron is obtained. Increased carbon separation also results through a volume increase, particularly by increasing the cross-section through the lower part of the shaft furnace. Carburization is also assisted in that the ratio of the reduction gas quantity supplied below the bustle plane is made as large as possible compared with the reduction gas quantity supplied in the bustle plane.

Patent EP-0213784-A3 (EP)
IPC: H05B44/00
Filed: 1986-08-05
Abstract: The output of a laser diode or L.E.D is amplitude 
modulated by varying the forward current through it. 
This is done by applying a dc current component from a 
first current source and an ac current component from 
another part of the circuit. The ac current component 
is applied to the laser diode l via an ideal impedance 
matching transformer which comprises four capacitors 
l0, ll, l2, and l3. One of the capacitors l2 is the 
internal capacitance of the laser diode l such that when 
the frequency of the modulating signal is varied and 
hence the response of the laser diode l varies, ideal 
matching is still obtained since the capacitor l2 
enables compensation to be made.

Abstract: A monoclonal antibody to a metal salt or a metal com­
plex is produced by a hybridoma cell line formed by in vitro 
fusion of mouse spleen cells which have been sensitized to 
the metal salt or the metal complex and cells from a myelo­
ma cell line, e.g. P3-AgX-653. The monoclonal antibody may 
be used in a process for the recovery of metal values from 
a solution or a dispersion or a slurry or the like containing 
a metal salt or a metal complex which includes the steps of 
contacting the solution or the like containing the metal salt 
or the metal complex with a support on which are immo­
bilized monoclonal antibodies to the metal salt or the metal 
complex so that a complex is formed between the mono­
clonal antibodies and the metal salt or the metal complex, 
and when the support has reached the desired metal value 
loading, eluting the metal values from the support with a 
suitable eluant and collecting the eluate containing the 
metal values. The monoclonal antibody may also be used in 
a method of detecting the presence of a metal salt or a metal 
complex in a sample.

data of the associative memory. A variety of improvements are 
made to the associative memory (1). For instance, a plurality 
of coincidence detection signal lines (16) of the associative 
memory (1) are divided into at least two groups, and one group 
among them is selected by switching means (5). Reference data 
of the associative memory (1) comprises three values consis­

Abstract: A method of attachment of a thermally conductive ele­

includes initial steps of forming an oxide-free preform (56) 
of a fusible metal alloy (50) by extrusion of alloy between 
two mold blocks or plates (36,40). During the extrusion, the 
oxide coating (54) is left behind so that the extruded alloy is 
essentially free of oxide. The extrusion takes place at a 
temperature elevated to approximately the liquidus tem­
perature of the alloy. The preform, which may be in the form 
of a pill (56) or section (74) of thin foil, is placed between 
interfacing surfaces of the thermally conductive element 
and the chip, and is then extruded along the interfacing 
surfaces under pressure and elevated temperature to form 
a thermally conductive, oxide-free bonding layer of superior 
thermal conductivity.
