Extensometer automatically measures elongation in elastomers

Extensometer, with a calibrated shaft, measures the elongation of elastomers and automatically records this distance on a chart. It is adaptable to almost any tensile testing machine and is fabricated at a relatively low cost

Neutrino Event Rates from Gamma Ray Bursts

We recalculate the diffuse flux of high energy neutrinos produced by Gamma Ray Bursts (GRB) in the relativistic fireball model. Although we confirm that the average single burst produces only ~10^{-2} high energy neutrino events in a detector with 1 km^2 effective area, i.e. about 10 events per year, we show that the observed rate is dominated by burst-to-burst fluctuations which are very large. We find event rates that are expected to be larger by one order of magnitude, likely more, which are dominated by a few very bright bursts. This greatly simplifies their detection.Comment: 14 pages, Latex2.09, uses aastex4.0 and epsf.sty, 3 postscript files. Minor revisions. To be published in ApJ Letter

Self-charging metering and dispensing device for fluids

A self-metering and dispensing device for fluids obtained from a pressurized fluid supply is discussed. Tubing and valving means permit the introduction of fluid into and discharge from a closed cylindrical reservoir. The reservoir contains a slideably disposed piston co-acting with a coil compression spring, with piston travel determining the amount of fluid in the reservoir. Once the determined amount of fluid is introduced into the reservoir, the fluid is discharged by the force of the coil compression spring acting upon the piston

Admiralty Litigation In Perpetuum: The Continuing Saga of Package Litigation and Third World Delivery Problems

Certain admiralty cargo issues are litigated frequently, often in search of a magical test which will preclude all further litigation. Three such issues are package limitations, the burden of proving the condition and quantity of cargo stowed within containers, and the point at which the ocean carrier delivers cargo at discharge and thus completes its duties under the contract of carriage. Despite the frequency with which these issues have been litigated, significant disagreement remains among the circuit courts as to their proper resolution. This article will examine the current state of judicial uncertainty in these areas and the indications given by the courts as the positions most likely to be adopted in the future
