Abstract: 1296305 Pressure-sensitive adhesive tape JOHNSON & JOHNSON 19 April 1971 [3 Feb 1970] .21010/71 Heading B2E [Also in Divisions D1 and D2] An adhesive, e.g. surgical tape, comprises (a) a web comprising (1) a randomly-dispersed blend of about 10-50% by weight (based on web) of wood pulp fibres, about 5-40% by weight (based on web) of hemp fibres, and about 4-20% by weight (based on web) of rayon fibres, all of said fibres having a length not in excess of half an inch, and (2) about 20-60% by weight (based on web) of a flexible binder dispersed throughout the blend, the web being linearly compacted without substantial creping to a length less than about 96% of its uncompacted length whereby an extensibility of at least about 8% of the compacted length is imparted thereto, and (b) a pressure-sensitive acrylate adhesive coated on one surface of the web. The binder may comprise cross-linked polyethyl acrylate. The adhesive may comprise the porous acrylate adhesive, e.g. a crosslinked blend of 2-ethylhexyl acrylate-vinyl acetate copolymer with 2-ethylhexyl acrylate-ntertiary-butyl acrylamide copolymer, applied by transfer coating, spraying, or roller. A release coating may be provided on the adhesive-free surface thereof and may comprise stearyl methacrylate/acrylonitrile copolymer preferably applied by gravure roll after application and curing of the adhesive. As shown in Figure 3, web 10 passes from roller 26 over guide roller 28 and then down into the nip 30 formed between the unyieldable surface 32 of heated drum 34 and the yieldably-supported rubber outer surface 36 of continuous rubber compacting belt 38. Belt 38 is held against surface 32  of drum 34 by means of nip roll 39, tensioning roll 40 and bottom guide roll 42. Because of the differences between the low coefficient of friction of surface 32 of drum 34 and the, high coefficient of friction of surface 36 of belt 38, the web tends to stick to the surface 36 and to slip on surface 32 so that the web is compacted longitudinally in the machine direction. Sufficient pressure is exerted with  respect to the web faces to prevent crinkling or creping of the body of the web. Belt 38 is cooled by water sprays 44 and 46 and water bath 48. The resulting compacted web 20 then passes over guide roll 56 and then positioning rollers 58, 60 and 62 which hold web 20 flat as it passes over radiant heater 64 which completes drying. Adhesive 66 is transferred on vessel 68 by partially-immersed transfer roll 70 to kiss roll 72, the volatile content of the adhesive being reduced or eliminated by flashing using infra-red heaters 74. The release coating is sprayed on the web by nozzle 76 and the product then enters curing oven 78.

Abstract: 1313123 Monostable circuits NAUCHNOISSLEDOVATELSKY INSTITUT POSTOYANNOGO TOKA MINISTERSTVA ENTERGETIKI I ELEKTRIFIKATSII SSSR 14 April 1971 9343/71 Heading H3T A monostable circuit has its pulse length determined to be a whole number of clock pulse intervals and comprises two transistors having a capacitor 4 from one collector to the base of the other, a capacitor 5 from said collector to the joined emitter, a resistor 6 from the base of the said other to the joined emitters and the collector of the said other connected with no intervening electronic components to the base of the said other transistor. In a rest condition, transistor 2 is on and transistor 1 off. During operation, alternate positive and negative clock pulses are applied at terminal 7. A first positive pulse turns transistor 2 off, causing capacitor 4 to charge via the base-emitter junction of transistor 1 and turn it on so the circuit is in a first quasi-stable state. The following negative pulse turns transistor 2 back on and transistor 1 is cut off by the positive voltage on its base to put the circuit in its second quasi-stable state. Capacitor 4 then starts to discharge through transistor 6. Each positive clock pulse tends to turn transistor 2 off but the magnitudes of the pulses at its collector are reduced by the capacitor 5 and only have an effect on transistor 1 when the capacitor 4 is nearly discharged, the reduced pulses then being large enough to turn transistor 1 off and bring the circuit to its first quasi-stable state again after a whole number of clock pulse intervals (Fig. 2, not shown). The circuit may be used as a frequency divider.

In Fig. 1 the burner 1 is supplied with gas via a pipe 2 provided with a manually operated tap 3 and a valve 4. The valve 4 is only open when a probe 5 is heated by the burner flame. The over-ride means comprises a valve 7 which by-passes the valve 4 and is connected via a mechanical linkage 8 and an operating member to the oven door, such that the valve is open and closed when the door is open and closed respectively. To ignite the burner 1 the oven door is opened, thus opening the valve 7, the main tap 3 is opened manually and the gas flowing to the burner 1 is ignited. Though not shown the tap 3 can be associated with a mechanical arrangement for insuring that the tap 3 cannot be turned on unless the oven door is open. The flames heat the probe 5, thus opening the valve 4 so that gas still flows to the burner 1 after the oven door is shut. In a second embodiment, Fig. 2, the by-pass valve 7 is connected to an ignition jet 9. To ignite the burner the oven door is opened and the main tap 3 turned on allowing gas to flow to the jet 9 where it is ignited by a permanent pilot 11. The jet 9 heats the probe 5, thus opening the valve 4 and allowing gas to flow to the main burner 1 where it is ignited by the jet 9. This jet 9 is then extinguished on closing the door. In a simpler embodiment the by-pass valve is omitted and the valve 4 is operated directly by the oven door.

Title: Method for analyzing registered images
IPC: G06T1/00
Filed: 1993-10-05
Abstract: A dual echo magnetic resonance imaging system produces two registered images of a patient in which the images have different contrast relationships between different tissue types. A two dimensional feature space histogram of the two images is produced and a separate centroid is located in the feature space histogram for each one of a pair of tissue types. A Cartesian coordinate system is defined in the feature space so that one axis of the system passes through the two centroids. Vector decomposition is employed to project each image element data point in the feature space onto a point on the one axis. The fractional quantity of each tissue type present in the image element is determined based upon the Euclidean distances from that axis point to the respective centroids. The fractional quantity is calculated for each element in the original images to form a pair of tissue images. The elements of a tissue image are processed to measure the amount of that tissue type in the imaged portion of the patient.
