Patent EP-0147948-A3 (EP)
Title: Non-intrusive agitation of a fluid medium
IPC: B01F31/42
Filed: 1984-11-26
Abstract: Impeller means 4 and 5 is provided in a container 2 for agitating fluid. The impeller means is movable to effect fluid flow. The impeller means includes an impeller 4 which is separate from a wall portion of the container to a point of which the impeller 4 is connected by supporting means 5. Movement of the impeller means relative to the wall portion is achieved by making the impeller means flexible.A vibrator 6 may be provided to cause movement of the impeller means. The characteristics of the components can be chosen so that when the vibrator is activated the impeller vibrates with a greater amplitude than the wall portion 3. This can be achieved by vibrating the wall portion at a frequency approximately equal to a resonant frequency of the impeller means.

IPC: D01D5/08
Filed: 1985-05-24
Abstract: Disclosed are a method and apparatus for forming a 
filament of disordered material. The apparatus is a melt 
spinning system (1) having a chill surface means (3) and 
pressurizable reservoir means (7). The reservoir means (7) 
are spaced from and beneath the chill surface means (3) 
and have an effluent orifice (11) located beneath the chill 
surface (3) and adapted to allow upward flow of the molten 
reservoir means contents to the chill surface (3). The meth­
od of the invention contemplates providing molten material 
in the reservoir means (7) and pressurizing the reservoir 
means to form a negative meniscus (11) of molten material 
in contact with the chill surface (3). In this way there is 
formed an edge defined filament of disordered material.

Title: Position-measuring device
IPC: G01D5/26
Filed: 1985-08-10
Abstract: A position measuring instrument comprising a graduation unit and a scanning unit. The graduation unit comprises a centering flange, a graduation carrier and a measuring graduation located on the graduation carrier. The scanning unit comprises a scanning component which comprises a scanning graduation and a stop. During assembly, the scanning unit is positioned radially with respect to the graduation carrier by positioning the stop against the centering flange. The scanning component may then be moved along a guide towards the measuring graduation. As the scanning component is moved towards the measuring graduation the stop no longer contacts the centering flange. A spacing foil removably sandwiched between the measuring graduation and the scanning graduation is used to position the scanning graduation at a predetermined distance from the measuring graduation. A locking means is then used to prevent further movement of the scanning component along the guide.

Title: Hydrolysis of lignocellulosic material
IPC: C13K13/00
Filed: 1985-09-10
Abstract: A continuous hydrolysis process for the hydrolysis of wood or other lignocellulose material into sugars and other products has an overall countercurrent flow of liquids and solids but an integral co-current flow of the liquids and solids as part of the process.As shown in Figure 2, woodchip or other feedstock is formed into a slurry which is acidified, pressurised and heated before being hydrolysed in reactors J. Three heat exchangers L1, L2 and L3 form a closed circuit in which exchanger L2 recovers heat from the slurry, L1 returns heat to the slurry and L3 makes up lost heat. The slurry is cooled before pressure reduction by pressure reducing means N and separation of the solids and liquid. The cooling prevents flashing to steam of part of the liquid in the slurry so that the process is single phase where generation of steam is avoided. After separation the solids can proceed to further processing or to discharge as lignin as indicated by arrow B. The liquid can proceed to further processing or discharge as indicated by arrow D.

Patent EP-0253587-A3 (EP)
IPC: H01F27/42
Filed: 1987-07-10
Abstract: Current sensing apparatus is described for measuring 
the helix current of a travelling-wave tube (TWT). The 
apparatus includes a helix current sense inductor (80) and a 
reference inductor. The sense inductor (80) includes windings 
(84, 86, 92) for receiving the cathode and collector currents 
(ICA, ICO) of the TWT and for receiving a bias current (IB), and 
also a sense winding (94). The cathode and the collector currents 
cause permeability of the core (82) of the inductor to vary in 
proportion to the difference between those currents, which is 
equal to the helix current. The bias current (IB) is supplied 
to the bias winding (92) to compensate the core (82) of the 
sense inductor for temperature-related permeability 
variations. The bias current (IB) is supplied by the reference 
inductor which has a core selected to have magnetic properties 
which match those of the core (82) of the sense inductor (80). 
A plurality of sense inductors (80) in conjunction with one 
common reference inductor may be used for sensing the respective 
helix currents in the TWTs in a multi-TWT array.

Abstract: Superconducting thin films of Yb₁Ba₂Cu₄O z , 
where Yb represents ytterbium, Ba represents barium, Cu 
represents copper, 0 represents oxygen, and z is a 
value ranging between about 6 to 8, are produced in a 
non-vacuum environment using Metallo-Organic Deposition 
techniques. An ink comprising the neodecanoates of the 
ytterbium, barium, and copper is formed and spun on a 
single crystal substrate of strontium titanate. The 
ink is dried in an air environment, heated in an air 
environment at a temperature sufficient to decompose 
the neodecanoates, about 500°C, and then annealed to 
promote recrystallization and grain growth of the 
remaining metal oxides. The annealing step is 
preferably accomplished using rapid thermal annealing 
techniques wherein the material is uniformly and 
rapidly heated to an appropriate temperature for an 
amount of time ranging up to about 2 minutes. The 
resulting films of material exhibit superconductive 
characteristics at elevated temperatures above the 
temperature of liquid nitrogen.

Abstract: The present specification discloses a gas-fired 
appliance comprising a burner arrangement (37,39) for 
the combustion of gas with a valve arrangement (43) 
located in a gas flow line to said burner arrangement 
(37,39). To thus adjust the burner arrangement (37,39) 
a person must approach the appliance and manually adjust 
the valve arrangement (43).  
     The present invention provides a receiver (51) in 
the appliance, the receiver (51) being adapted to 
control the opening and/or closing of the valve 
arrangement (43) in response to signals received from a 
transmitter (53) operable at a position remote from the 
appliance. Thus the burner arrangement (37,39) can be 
controlled at a distance. This is especially useful for 
the aged and infirm, particularly with regard to gas 
fires. The present invention also provides a valve (1) 
which is opened by a surge current which then reduces to 
a value sufficient only to hold the valve (1) open 
against the force of a spring (21).

Abstract: The flow of work requests in a server driven process to process 
communication environment is described. Logical connections 
between processes and bus managers interfacing bus units (50, 
52) to an I/O bus (54) are assigned to connection groups for 
management by the bus managers. Each bus unit has its own 
connection groups for the logical connections. Bus unit 
resources are assigned to each connection group based on 
performance factors, and a series of bus unit messages are used 
to control the flow of work so that a group which has no more 
resources will not accept further work requests. The 
originator of the work requests will resequence rejected work 
requests and resend them when the connection group has freed up 
resources. A further mechanism is provided to facilitate work 
consistent with the server driven architecture when bus units 
do not have adequate DMA capabilities. Two ways of reversing 
control of transfer of work requests and data so that the 
server need not have master DMA capability are presented. 
Management of storage in a remote processor is used to transfer 
work and its associated data into storage accessible by a bus 
unit with slave DMA capability. The slave DMA bus unit then 
transfers the information into storage it manages. In another 
way of reversing the flow, a bus unit message is used to make 
the original server a requestor. The bus unit message contains 
information which varies the request sent by the requestor. In 
this manner, the server, which was the original requestor 
transfers information using its master DMA capability flow.
