Patent EP-0053057-A3 (EP)
IPC: F01N3/22
Filed: 1981-10-27
Abstract: A vehicle emissions control system includes an air pump 
(12), a catalytic converter (22) communicated to the air 
pump, and a bleed control valve (28) which controls the 
quantity of air communicated from the air pump to the 
catalytic converter. The bleed valve (28) includes a support 
arm (50) which suspends a valve element (40) adjacent a 
tapered valve surface (36). The support arm (50) relaxes in 
response to repeated flexing due to the pulsating output of 
the air pump (12). Accordingly, when the vehicle is new, the 
valve element (40) is held away from the valve seat (36) to 
permit substantially uninhibited communication through the 
bleed valve (28) so that almost all of the air which would 
otherwise be communicated to the catalytic converter (22) is 
bled off. As the vehicle is used, the support arm (50) relaxes, 
which permits the valve element (40) to move progressively 
closer to the valve seat (38), thereby decreasing the quantity 
of air bled off through the bleed valve (28) to thereby 
progressively increase the quantity of air communicated to 
the catalytic converter (22).

retour de balayage vertical, emmagasine un signal représen­
tant une tension et maintient celle-ci pratiquement constante 
pendant la période de balayage vertical et qui est précédé 
par un réseau correcteur (41, 41a) permettant d'augmenter le 
gain en boucle ouverte de la boucle statique.

Patent EP-0097455-A3 (EP)
IPC: G01N33/48
Filed: 1983-06-09
Abstract: A fluid processing apparatus and method which utilizes 
centrifugation to separate constituent components of e.g. 
blood, in a flexible bag (8). The less dense separated 
components e.g., supernatant, is expressed from the bag (8) 
by centrifugal force acting on a plate (15) adjacent the bag 
and the more dense component (e.g. RBC's), remains. The 
bag (8) is oriented at a double angle in the centrifuge rotor 
(28) so that less dense component accumulates at one 
location (A) and more dense at a second location (C) 
diagonally opposite the first location, thus facilitating remov­
al of the less dense component to a further bag (2) and 
washing of the more dense component in the bag (8) by 
wash solution expressed from a still further flexible bag (20) 
by centrifugal force acting on a plate (17) adjacent the bag.

Title: Coin testing apparatus
IPC: G07F1/04
Filed: 1984-07-26
Abstract: @ A coin testing apparatus subjects a coin inserted into a coin entry (1) and rolling down an inclined track (2) to testing at a testing station (3) comprising sensors (4,5,6) which may for example be inductive sensors. If a coin is found to be acceptable an accept signal is generated and this causes gate mechanism (8) to open to permit the coin to access accept path (9), the gate mechanism (8) being normally closed so that unacceptable coins can only access a reject path (10). A post-gate detector (11) in the accept path (9) senses the passage of an accepted coin and serves to close the gate mechanism (8) and also to determine allocation of a customer credit. A pre-gate detector (12) upstream of the gate mechanism (8) has its output logically processed with the accept signal produced when an acceptable coin is tested and/or with the output of the post-gate detector (11).

Abstract: Sheets (126) of wrapping film are drawn into a wrapping 
machine from a continuous film source (108) to accom­
modate large girth packages (120W). Predetermined lengths 
of film corresponding to the entering lengths of the pack­
ages (120W) to be wrapped are initially drawn into the 
machine, with additional film being drawn in accordance 
with the girth dimensions of the packages. In a first embodi­
ment, the additional film is drawn from the source (108) by 
fully elevating packages into the film with the stress thus 
produced pulling the additional film required. In a second 
embodiment, a secondary package pusher (134) is connect­
ed to a rear underfolder (128) such that as the film is folded 
beneath a package, any portion of the package exceeding 
a given length is pushed from the wrapping station beyond 
a film edge-engaging position to draw additional film ap­
proximately equal in length to the extended portion of the 
package. In a third embodiment, the film is drawn from the 
source (108) by means of a gripper (102, 136) which is 
pivoted to draw additional film in accordance with the girth 
of a package as determined by the entering length of the 
package.

Patent EP-0198346-A3 (EP)
IPC: H01L45/00
Filed: 1986-04-04
Abstract: A threshold device (10,54,82) is provided 
which passes very little current when the voltage 
applied across it is below its threshold voltage and 
which can pass a large amount of current when the 
voltage applied across it exceeds that threshold. The 
threshold device comprises a common body (12,62) of 
deposited amorphous semiconductor material and two 
separate electrical contacts (18,19), each having a 
junction forming portion (20,21; 60,64; 52,65) in 
contact with the common body. The junction forming 
portions each form a junction (22,24) having a 
depletion region (26,28) in the semiconductor material 
of the common body. As a result, when a voltage is 
applied between the two contacts, one of the junction 
is forward biased and the other is reverse biased. 
Both the spacing between the junctions and the 
electrical properties of the common body and the 
junctions are such that when the threshold voltage is 
applied between the contacts, the depletion region of 
the reverse biased junction extends all the way to the 
depletion region of the forward biased junction, 
greatly increasing the conductivity between said two 
contacts. The threshold voltage at which such a 
punch-through of the depletion regions occurs is less 
than the voltage required to cause avalanche breakdown 
across the reverse biased junction. Among other 
things, such threshold devices are used as isolation 
devices (54,82,92,94,102,104) for the individual 
pixels (42) of a light influencing display (40).

be disposed at one end of the load bearing arms and an op­
tical detecting system (28, 26) to be disposed at opposing 
ends of the load bearing arms. The target includes a plural­
ity of light sources generally disposed in a plane and at 
least one light source disposed outside the plane. The op­
tical detecting system includes a first and second linear de­
tector array adjacently disposed with longitudinal axes per­
pendicularly oriented. Each array senses target motion 
along a single line parallel to its longitudinal axis. An imag­
ing lens and a cylindrical lens are provided for each array to 
focus images from the target light sources into lines orient­
ed perpendicular to the longitudinal axes of the respective 
arrays. The optical detecting system resolves translational 
displacement of a target and associated robotic arm end 
along with pivotal changes in the orientations of the target 
and robotic arm end.

Abstract: Each IDT (inter-digital transducer) (22, 24) of a SAW (surface acoustic wave) device (20) is formed on a thin resistive doped silicon film having the same pattern as the IDT, which improves adhesion of the IDT to the substrate. The silicon film also constitutes electro-acoustic absorbers (26, 28) between the IDTs and edges (40, 42) of the substrate, and can have a linearly tapered edge adjacent to each IDT to suppress reflections at the absorber boundary. The SAW device is formed by sputtering silicon onto the substrate, subsequently forming the IDTs, and then etching the silicon from areas where it is not wanted.
