Title: Method and device for controlling a gas stream
IPC: G05D7/03
Filed: 1987-12-15
Abstract: The evacuation of foul smelling gases from the interior of a toilet bowl is effected by a fan which is driven by an electric motor and conveys the gases from the bowl through a control chamber in the flushing tank and into an evacuating conduit which is connected to the drain pipe. The motor is started in response to closing of a master switch which is distinct and preferably remote from an actuating knob which must be lifted or otherwise moved in order to enable a body of flushing liquid to flow from the tank into the bowl. A siphon is provided to permit liquid to flow from the interior of the control chamber into the interior of the flushing tank in response to rising pressure in the control chamber. Such pressure, which rises in response to starting of the motor, causes a lowering of the liquid level in a portion of the control chamber and a rise of the liquid level in another portion of the control chamber so as to establish in the siphon a continuous column of liquid which flows by gravity from the control chamber into the flushing tank so as not to waste the liquid which normally seals the inlet for gaseous fluid from the outlet for gaseous fluid in the control chamber.

Abstract: An industrial, digitally controlled processing system 
including two nominally identical electronic devices 
connected in the system in a manner such that one of the 
devices functions as an active device in the system and the 
other device functions as a standby device, in which each 
device includes a back-up control unit including an optical 
fiber link for establishing communication between the device 
and the other nominally identical device, the unit being 
operative for determining whether the device is presently 
functioning as an active or standby device and for receiving 
signals indicating whether the other nominally identical 
device is functioning as an active or standby device, and 
for synchronizing the operation of the device with that of 
the other nominally identical device, and having a switch 
responsive, when the device is functioning as the standby 
device, to the occurrence of a failure in the other nominally 
identical device for causing the device to begin operating as 
the active device.

IPC: G01D5/248
Filed: 1987-11-26
Abstract: Quadrature input signals (26,28) from an 
opto-electronic or magnetic readhead (20) which is 
movable relative to a periodically marked scale (22), 
are respectively multiplied by quadrature reference 
signals from a reference oscillator (32) in multipliers 
(52,54). The resulting signals are added together in a 
mixer (56) to give a signal (S) which is at a frequency 
which is the reference frequency shifted by the 
frequency of the input signals. This signal (S) is 
then compared with the reference signal. The reference 
signals are generated from a high frequency clock (30) 
which is subsequently used to compare the period of the 
reference signal with that of the signal (S), giving 
outputs which interpolate the position of the readhead 
(20) within the pitch of the marks on the scale (22).

Patent EP-0297626-A3 (EP)
IPC: G06F9/22
Filed: 1982-08-06
Abstract: A control unit for a functional processor is disclosed 
which minimizes programming complexity by eliminating 
data transfers and the transfer control associated with 
two level memory systems and which improves flexibility 
in program task changeovers in pipelined arithmetic 
architectures. This is accomplished by employing 
common page addressing for accessing memory address 
stacks for storing either main memory addresses or 
address increments, coefficient address stacks for 
storing coefficient memory addresses or address incre­
ments, and microinstruction sequencing control branch 
stacks for storing branch and loop control parameters. 
This permits chaining of long sequences of signal 
processing subroutines without external control and the 
associated execution time overhead. An additional 
feature is a revolving buffer operation in which a 
plurality of main memory modules are cyclically connected 
to each of a plurality of scratch pad buffers in the 
arithmetic unit in a synchronous manner so as to 
maximize the throughput of the combined operation of 
memory transfers, arithmetic processing and I/O transfers. 
In another feature, the controller employs a dual 
clocking arrangement whereby scratch pad storage elements 
and arithmetic elements can be selectively controlled 
to operate at twice the rate at which microinstructions 
are accessed from the microprogram store. The re­
sulting controller for a pipelined arithmetic archi­
tecture provides a closely coupled control of looping 
and branching control operations with storage accessing 
operations and pipelined arithmetic operations to 
provide for immediate and flexible responses to changes 
in programming tasks.

IPC: B32B3/04
Filed: 1984-04-11
Abstract: For co-molding a plurality of articles from a plurality of 
polymeric materials, a preferred molding apparatus has a 
plurality of valve-controlled co-injection nozzles (296) and 
injection cavities (102). The polymeric materials (A to E) 
are melted and fed from their sources (202, 204, 206) by 
screw extruders (214, 216, 218) to a set of rams (232, 234, 
252, 260, 262) which appropriately pressurize and move 
streams of the polymeric materials to feed blocks (296) each 
associated with or forming part of a respective nozzle (296) 
for injection into the related cavity (102). The streams 
leaving the rams (232, 234, 252, 260, 262) are conveyed along 
respective runner ducts (220, 222, 250, 257, 258) to a runner 
extension member (276) in a runner block (288), and in the 
runner extension each material stream is divided into a 
plurality of branch streams. Each branch stream is ducted to 
flow splitters in the runner block (288) for further division 
into plural feed streams equal in number to the number of 
nozzles (296), and the separate feed streams are then fed one 
to each nozzle (296). The apparatus is configured such that 
for each material, the plural feed streams reach their 
respective nozzles (296) after passage along ductings of the 
same length and geometry to ensure that the streams enter 
their nozzles as nearly as possible in the same condition, 
ready for injection. Each nozzle (296) receives the 
polymeric materials (A to E) as separate feed streams and 
combines them appropriately into a plural-layer, 
plural-material stream for injection. The nozzles all have 
pin and sleeve valves (800, 834) to control admission and 
flow of the different materials to their central channels 
(240) wherein the combined stream is formed. Valve operation 
is under microprocessor control (2040) and the valves - which 
are effectively substantially identical - are coupled to 
common valve actuating cams (850, 856) for operation in 
 
 
unison, so that at any instant in the molding cycle the 
combined streams formed in the nozzles (296) for injection 
are as near as possible identical to one another. By 
appropriately controlling the pressures of the polymeric 
material streams and by appropriately controlling the timing 
of valve operating movements, precise control is obtainable 
whereby e.g. internal layers of the injected articles are 
positioned where best suited depending on the service 
required of the articles.  
     The method and apparatus are applicable to the 
production of injection or injection blow molded articles 
such as containers for commestibles and beverages.

members along an outer peripheral surface of the 
mandrel (M). A positioning device has a pair of guide 
members (4,5) mounted on an inner surface of each of 
the support plate members for engaging opposite side 
edges of one of the webs.
