Patent EP-0038506-A3 (EP)
IPC: G09G3/00
Filed: 1981-04-13
Abstract: Die Erfindung betrifft eine Schaltungsanordnung zur 
Ansteuerung einer Mehrzahl von optoelektronischen Anzei­
geelementen, z.B. Leuchtdioden, z.B. zur Anzeige von Vermitt­
lungs - und/oder Betriebszuständen, wobei die Anzeigeele­
mente matrixmäßig angeordnet sind und über die Matrix­
steuerleitungen ansteuerbar sind.  
     Die Aufgabe der Erfindung besteht darin, die Anzeige­
elemente so zu beschalten, daß bei gleicher Ansteuerung 
über die Matrixsteuerleitungen ein geringerer Stromver­
brauch vorliegt.  
     Dies erfolgt dadurch, daß bei gleichzeitigem Ansteuern 
von Anzeigeelementen (LED1, LED3) in unterschiedlichen 
Matrixspalten diese Anzeigeelemente hintereinander 
geschaltet werden und daß bei Verwendung von Anzeigee­
elementen aus nur einer Matrixspalte (LED1, LED2) (LED3, 
LED4) oder bei keiner Anzeige durch eine Strombegrenzung 
(BG) der passende Abschlußwiderstand für die ferne Strom­
versorgung der Anzeigeeelemente hergestellt wird.  
     Hieraus ergibt sich der Vorteil, daß bei Hintereinander­
schaltung von zwei Anzeigeelementen ein Anzeigeelement 
bereits einen Teil des sonst je Anzeigeelement notwendigen 
Vorwiderstandes darstellt und auch bei partiellem Anzeige­
elementbetrieb bei unterschiedlich langen Zuleitungen ein 
optimaler Eingangswiderstand für die Stromversorgung über 
die Teilnehmerleitung gegeben ist.

Title: A body structure and nozzle for enhancing the flow of drilling fluid in a rotary drill bit
IPC: E21B10/52
Filed: 1981-05-25
Abstract: A rotary drill bit for drilling a bore hole in the surface of the earth is provided in which the drill bit comprises a body having a duct therethrough for carrying drilling fluid. A conical cutting head having an axis at an acute angle with respect to the axis of the drill bit .is mounted in the cutting head. An elongated nozzle is positioned at the end of the duct for injecting the drilling fluid into the bore hole. The nozzle has an opening which opens into the bore hole wherein the longitudinal center line of the opening follows the locus of the mid-point between the side wall of the bore hole and the outermost circumference of the cutting head. Drilling fluid injected through the nozzle removes detritus from between the teeth and the cutting head at the bottom of the bore hole. The body of the drill bit has a first portion having a truncated conical surface with the axis of the truncated cone coinciding with the axis of the cutting head. The surface of the truncated cone is tangent to the side surface of the bore hole at a line on the opposite side of the body from the nozzle. This forms a passage between the surface of the truncated cone and the side surface of the bore hole for the upward flow of drilling fluid and detritus.

Title: Positioning reel
IPC: F21V21/18
Filed: 1983-01-31
Abstract: A positioning reel (10) for suspending a body (17), such as a lightweight tool, at any vertical position within the limits of the suspension cord (18) length is disclosed. An adjusting screw (38) which regulates a clutch-type tensioning brake (22, 30, 32) permits the supporting force of the positioning reel to be set to equalize the weight of the suspensed body such that little effort is required to lower the suspended body. With the downward external positioning force removed from the suspended body, it remains in its present position. The suspended body can be easily raised by applying an upward external force equal to slightly more than the weight of the suspended body. When raising the suspended body, a clock-type coil spring (24) actuates a spool (22) within the positioning reel for retracting the suspension cord. A spring-type override clutch (22A, 62) permits reeling in the suspension cord while bypassing the tensioning brake. With the upward external force removed from the suspended body, it will again remain in its present position.

IPC: B65D5/70
Filed: 1983-06-15
Abstract: The drawings and description disclose a liquid carrying 
paperboard carton having straw opening means formed in a 
side wall panel thereof. The straw opening means includes a 
first tear strip formed on the side seam-supported edge of 
one side panel by spaced laterally-extending die cuts formed 
all the way through the paperboard layer, and extending 
from a side edge across a portion of the width of the 
underlying panel to a vertical score line for forming a flexible 
hinge. A second tear strip is formed on the underlying side 
seam by die cuts formed through the thermoplastic coating 
only, directly beneath the first tear strip. An arcuate cut is 
formed on the panel adjacent the side seam through the 
coating thereon so as to interconnect the inner ends of the 
second tear strip. The arcuate tab formed by the latter cut 
breaks away from its panel when the carton is formed, and 
serves as a starter tab for lifting the first and second tear 
strips, whereupon the tear strips may be peeled back past a 
notch or edge of the underlying side seam to accommodate 
the insertion of a straw therein.
