Title: Measuring circuit for an ionic current
IPC: F02P5/04
Filed: 1984-10-23
Abstract: A measuring circuit for the ionic current measurement in the combustion chamber of an Otto engine is disclosed. The circuit has an ignition transformer the secondary coil of which supplies an ignition circuit. On the side carrying the positive voltage of the ignition pulse, the coil is connected to ground and, on the side carrying the negative voltage of the ignition pulse, it is connected to the ignition spark gaps via a distributor. The circuit has, inserted into the ignition circuit, a parallel circuit of a high-voltage Zener diode connected in the non-conducting direction related to the ignition current, and a capacitor as the measuring voltage source. The present invention supplies the measuring voltage to the ignition spark gap without circuit elements influencing its sensitivity. A parallel circuit is connected between the side carrying the positive voltage of the secondary coil and ground. The secondary coil is connected via diodes immediately to the ignition spark gaps such that the anode of each diode is connected to the side of the secondary coil carrying the negative voltage of the ignition pulse. A coupling capacitor for decoupling of an ionic current signal is coupled to the primary winding of the ignition transformer.

Abstract: The invention is a method for providing an electrically con­
ductive path through a substrate. It is especially useful for elec­
trically connecting together electrically conductive paths (25) 
on opposite sides of a circuit board (20). The method is charac­
terized by the steps of forming a passage (21) through a sub­
strate (20) that connects to at least one conductive path (25) 
on each side of the substrate (20), filling the passage (21) with 
an electrically conductive powder (10), applying pressure with 
a die (30) to obtain a compacted powder (11) in the passage 
(21), and then heating the compacted powder (11) to a tem­
perature that increases the conductivity and ductility of the 
compacted powder (11) and its adhesion to the substrate (20) 
without adversely affecting the shape or condition of the sub­
strate (20).

IPC: B03D1/02
Filed: 1985-05-13
Abstract: An improved method and apparatus for froth flotation 
separation of the components of a slurry, having particular 
utility for the beneficiation of coal by the flotation separation 
of coal particles from impurities associated therewith, such 
as ash and sulfur. In this arrangement, a forward product 
stream is formed in which a mixture of the particulate matter 
slurry and the chemical reagents is sprayed through a nozzle 
at a first relatively low pressure onto the surface of water in a 
forward stream flotation tank to create a floating froth phase 
containing therein a first quantity of the particulate matter. 
The remainder of the particulate matter slurry separates 
from the froth phase by sinking in the water, and the froth 
phase is separated as a first product. The remainder of the 
particulate matter slurry is then directed to a scavenger 
product stream in which the separated slurry is sprayed 
through a second nozzle at a second higher pressure onto 
the surface of water in a second scavenger stream flotation 
tank to create a floating froth phase containing therein a 
second quantity of the particulate matter. The second froth 
phase is then separated as a second product. The amounts of 
the products recovered in the first and second product 
streams are substantially independentially adjustable by con­
trolling the first and second spraying pressures.

IPC: E01B7/00
Filed: 1985-01-25
Abstract: An improved railroad stub switch is described in which 
the axial rail tension or compression forces due to tem­
perature fluctuations are transmitted through the switch by 
means of radius arms connected to both the switch and fixed 
rails, thereby eliminating the need for expensive expansion 
joints at the switch. In a preferred embodiment, interlocking 
point shoes are also employed so as to hold the butt ends in 
vertical and horizontal register and transmit a signal to the 
trailing side rail of the impending approach of a load from the 
approach side rail, thereby reducing batter on the trailing 
side rail.

Abstract: A clutch servo for a vehicle cable-operated clutch system 
has a housing (1), an input member (3) to which an input 
force is applied by the cable (2) which has an inner cable (2a) 
and an outer sheath (2b), an output member (4) connected to 
a clutch, and a movable wall (5) for augmenting the output 
force which acts through the output member (4). The 
movable wall (5) is operated by a fluid pressure chamber (6), 
pressurisation of which is controlled by valve means (8) in 
response to the input force. In one construction the inner 
cable (2a) is movable relative to the movable wall (5), and a 
locking means (7) is incorporated to lock the inner cable and 
the movable wall against relative movement when the 
movable wall is not in its retracted position. This ensures that 
the servo is not affected by adjustment of the cable to 
compensate for clutch lining wear when this adjustment is 
performed between the servo and the pedal. In another 
construction the servo includes adjuster means in the form 
of locking means (62) between the housing (1) and an end 
(58) of the sheath (2b), which is inoperative when the inner 
cable (2a) is retracted to allow relative movement between 
the end (58) and the housing, and which operates when the 
inner cable (2a) moves from its retracted position to lock the 
sheath (2b) and the housing (1) against movement. A valve 
actuating means (9) in the form of a lever (35; 70; 86) is also 
incorporated to transmit the input force from the cable to the 
valve means, operation of which is controlled by the input 
force and an opposing force in resilient means (51, 52; 70; 
91).

Patent EP-0223558-A3 (EP)
IPC: G02B30/27
Filed: 1986-11-13
Abstract: The invention relates to the 
production of three dimensional images for 
direct viewing or for recording on a 
sensitised recording surface. Hitherto, three 
dimensional images have been produced by a 
two-stage process, and the resultant images 
have needed to be viewed using special 
equipment. To produce such images in e.g. 
photography, either a multiple lens camera has 
been needed, or a means to allow a single lens 
camera with a slit plate, to move along a 
horizontal track. The images so produced 
exhibit a high degree of so-called flipping. 
More recently, an attempt to overcome these 
problems proposed the use of a wide aperture 
lens behind a slit plate. This allows the 
object to be viewed from various and 
continuous directions but the image is a 
spatial image that is inverted in depth, and 
the process remains as a two-stage process. 
The object of the present invention is to 
provide a method and apparatus for the direct 
production of integral parallax orthoscopic 
panoramagramic images, which objective is met 
 
 
by a process comprising directing at an object 
a means of gathering and focussing incoming 
radiation from the object of a wavelength to 
which said means is suited, positioning to 
either side of said gathering and focussing 
means a grouping means for producing a number 
of groups of individual waves, each group 
emanating from a part of said object, said 
grouping means generating an image in 
pseudoscopic form, and a means of encoding 
the pseudoscopic image as discrete parallactic 
information on a single plane, for subsequent 
viewing as an orthoscopic image.

Abstract: The present invention provides significant improve­
ments in the design and performance of a specific type of 
Rotary Membrane Filter (RMF) apparatus which has the cap­
ability of separating particles from a fluid having the same 
and nearly the same density as the particles by utilizing shear 
to achieve separation, not centrifugal forces. A particular app­
lication for the apparatus is in the processing of fluid suspen­
sions in which the suspensions contain fragile particles which 
are subject to damage due to excessive shear stresses. The 
prior art describes processing at constant shear rate, whereas 
the present invention provides the design and optimization of 
operation of such an apparatus at constant shear stress, 
which is maintained at a value below that at which significant 
damage to the fragile particles is encountered. The use of the 
invention is plasmapheresis (blood separations) is described 
in detail, it being understood that the teachings of the inven­
tion are also directly applicable to other fluids containing 
fragile particles.  
     The application of the RMF in a continuous flow pro­
cessing system designed to extract blood plasma from a 
donor is described, including return of corpuscular com­
ponents to the donor.
