Abstract: A floatation device. The floatation device may comprise: at least two float portions and one or more fasteners. The two float portions may be opposing halves of a floatation float configured to form a float when combined. The one or more fasteners may be aligned and positioned on the outer side of the two float portions, such that, when the fasteners engage with each other, the two float portions form as a float. The fasteners may be strap fasteners. Accordingly, the float portions may fasten together on a fishing line after mating the fasteners. To increase the strength of the fastening the devices, an adhesive fastener may be included on the contact surfaces of the float portions. Each float portion may also comprise a recess and a projection for mating or engaging. The floatation device is particularly useful as a floating support for seines and commercial fishing nets.

Abstract: The present invention is floatation device for seines or fishing nets, which preferably includes: at least two cork portions and one or more pairs of fastener inserts. The two cork portions are preferably opposing halves of a floatation cork configured to form a cork when combined. The one or more pairs of fasteners are preferably aligned and embedded inside the two cork portions, such that, when the one or more pairs of fasteners engage, the two or more cork portions form as a cork. Accordingly, the cork portions preferably fasten together on a fishing line after mating the fastener inserts. To increase the strength of the fastening the devices, an adhesive fastener may be included on the contact surfaces of the cork portions. The floatation device is particularly useful as a floating support for seines and commercial fishing nets.

Abstract: Whipstocks and deflectors comprising a degradable composition, and methods of using same are described. In one embodiment the degradable composition consists essentially of one or more reactive metals in major proportion, and one or more alloying elements in minor proportion, with the provisos that the composition is high-strength, controllably reactive, and degradable under defined conditions. Methods of using degradable whipstocks in oilfield operations are also described. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 C.F.R. 1.72(b).

Abstract: A tire monitor for use in conjunction with a remote tire monitoring system of a vehicle includes in one embodiment a dual-axis accelerometer and a control circuit. The control circuit determines position information such as the right/left position of the tire monitor on the vehicle in response to an acceleration signal from the dual axis accelerometer. The tire monitor transmits tire data and the position information to a control unit of a remote tire monitor system. The control unit determines additional position information such as front/rear position of the transmitting tire monitor by detecting signal strength of the transmission. This allows the system to automatically re-learn the position of tire monitors on the vehicle, even after tire rotation.

Abstract: An N-channel radiation-hardened transistor has source and drain regions that are fully enclosed by an intrinsically radiation-hardened thin gate-oxide. which substantially reduces radiation-induced intra-device and inter-device leakage currents. The width of the polysilicon gate directly between the source and drain can be the minimum feature size allowed by the design rules of a given process. The width of the polysilicon surrounding the device is chosen by design rules from the minimum allowed to some wider value to allows the polysilicon overlap to be sufficient to self-align the source and drain without compromising the doping under the field region. The polysilicon should be sufficiently wide so that it completely overlaps any transitional oxide such as LOCOS or trench oxide. The gate capacitance of the N-channel transistor can be tuned to balance SEU hardness and switching performance.

Abstract: The invention provides a method and apparatus (10) for loading a sensitized flowable explosive into a borehole. The apparatus (10) is portable and comprises containers 14, 16 which are pressurizable, for containing an explosive under pressure. Containers 14, 16 have closeable explosive inlets, closeable explosive outlets, and closable fluid inlets. In accordance with the method gas bubbles are dispersed into an explosive base to provide a sensitized explosive which is fed as a batch into the portable containers. The containers are pressurized to de-sensitize the explosive, after which the containers are conveyed to a borehole where the explosive is loaded from the apparatus into the borehole.

Abstract: A marble runway type of game apparatus for children which provides amusement and requires skill and which is of the knock-down type and formed of readily interfitting parts of any suitable material and may be easily molded of any suitable plastic.

Abstract: A frequency synthesizer of the phase lock loop type including a reference frequency source, a voltage-controlled oscillator and a frequency divider connected to the oscillator output to divide the output frequency by a selectively-variable integer N. The outputs of the frequency divider and the reference frequency source are applied to a phase comparator which has an output connected to a filter. The filter output is applied through a multiplier, having a multiplication factor n proportional to N, to the input of the voltage controlled oscillator. The frequency divider and the multiplier are controlled by the same control means in order to keep the loop gain constant, irrespective of the amount of change in N.
