Title: System for producing a liquid spray curtain for application to a moving web
Inventor: REBA IMANTS
IPC: B05B7/08
Filed: 1981-05-13
Granted: 1984-12-20
Abstract: A method and a system are provided for producing a continuous liquid spray curtain which, when sprayed onto a moving surface, covers essentially the entirety of that surface without substantial streaking thereof. The subject spray curtain is produced by discharging a continuous air curtain at a relatively high velocity of at least 600 feet per second (183 metres/sec.). A plurality of liquid streams are at the same time discharged from a liquid discharge means (37) at a relatively low velocity of not more than about 20 feet per second (6 metres/sec.). The air curtain contacts the liquid streams at a minimum contact angle of between about -10 DEG  and about +30 DEG , measured from the center line of the liquid discharge means. The contacting air curtain atomizes the liquid streams and forms the subject high velocity, uniform, liquid spray curtain.

Title: A blood sampling set
Inventor: AAS FLEMMING
IPC: B01L3/14
Filed: 1981-10-29
Granted: 1985-10-03
Abstract: A capillary tube containing a sample is anaerobicly sealed by means of closure caps each comprising an end wall and a skirt portion. Each open end of the capillary tube is sealed by inserting the open tube end into the cap skirt portion, and in order to avoid that a volume of air is forced into the capillary tube, the space defined between the open tube end and the cap end wall is vented to the atmosphere through one or more venting passages defined in the walls of the closure cap or between the inner surface of the cap skirt portion and the adjacent outer peripheral surface of the capillary tube. The open tube end is brought into sealing engagement with sealing means on the cap end wall, and frictional engagement established between the inner surface of the cap skirt portion and adjacent outer peripheral surface parts of the capillary tube secures that said sealing engagement is maintained.

Title: Apparatus for measuring the flow rate of molten material
Inventor: RANSHEIM ANDERS P
IPC: G01P5/18
Filed: 1981-12-14
Granted: 1987-04-23
Abstract: Apparatus for measuring the flow rate of a flow, stream or jet (1) of a molten, radiation-emitting material, in particular molten glass or ceramic or mineral materials, comprising two radiation detectors (S1, S2) arranged to detect the radiation emitted from a limited section of the material flow at two mutually spaced locations along its path. The output signals of the detectors are applied to signal-processing circuits (ST1, ST2), which discriminate therefrom all pulse-like amplitude variations (P) exceeding a given specific magnitude and provide corresponding signal pulses (P min ) on their outputs, said pulse-like amplitude variations originating from randomly occurring, local deviations in the radiation from the material flow (1) due to the presence of gas bubbles in the material. The time interval between the occurrence of a signal pulse on the output of the signal-processing circuit (St1) of the upstream detector (S1) and next following occurrence of a signal pulse on the output of the signal-processing circuit (ST2) of the downstream detector (S2) is determined by starting a digital counter (R), which is driven at a constant frequency, with the first-mentioned signal pulse and stopping the counter with the second signal pulse. The resultant count in the counter (R) is transferred to a calculating unit (D), which calculates the flow rate of the material flow on the basis of sad count and the distance (L) between the detecting locations of the detectors (S1, S2). A gating circuit (B) is connected between the signal-processing circuit (ST1)  of the upstream detector (S1) and the counter (R) for blocking the transfer of any signal pulse occurring on the output of said signal-processing circuit within a given time interval after a preceding occurrence of a signal pulse on said output.

Abstract: An improved process and an improved composite bearing material produced thereby comprising a hard metal backing strip having leaded-bronze bearing lining tenaciously bonded to at least one face surface thereof and wherein the bearing lining is characterized by having the lead constituent thereof substantially uniformly distributed throughout the lining matrix in the form of extremely finesized particles providing improved operating characteristics to the bearing materials fabricated therefrom. In accordance with the process aspects of the present invention, the steel backing strip is provided with a metallic plating composed predominantly of nickel to at least the face on which a prealloyed leaded-bronze powder of a controlled composition is applied and is thereafter sintered at a controlled temperature for a short period of time sufficient to effect a liquid phase sintering of the powder together and the formation of a bond between the powder layer and the metallic plating on the face of the backing strip whereafter the sintered composite strip is cooled and is compacted usually at temperatures below about 300 DEG F. (149  DEG C) to effect a substantially complete densification of the powder layer. The composite strip is again reheated at a controlled temperature and for a brief period of time sufficient to further enhance the physical properties of the bearing lining and to further enhance the strength of the bond between the lining and backing strip under controlled conditions to inhibit growth of the finesized lead particles into undesirable larger particles. The composite strip is thereafter again cooled and may be subjected to a further compaction at moderate warm temperatures to achieve still further densification and to improve the physical properties and sizing of the composite strip.

Abstract: Submicron x-ray lithography using a single shot of ultraviolet laser energy of one nanosecond (ns) duration and of relatively low energy to produce an x-ray pulse for exposing a resist to obtain a submicron pattern thereon. The incident x-ray flux used is about an order of magnitude smaller than heretofore required to obtain a comparable exposure with similar x-ray resists. A shield which transmits the x-ray pulse, but blocks the plasma material, is thermally coupled to the resist and heats the resist by transfer of the heat from the plasma thereto, upon exposure of the resist by the x-ray pulse.
