Abstract: A detonator for initiating a firing of a shaped charge in a gun is configured to include a housing having first and third conducting portions and a second insulating portion, which is sandwiched between the first and third conducting portions; an initiator located fully inside the first conducting portion or the third conducting portion; a first electrical line electrically connecting the initiator to an internal wall of the third conducting portion; and a second electrical line electrically extending from the initiator to the first conducting portion, through the entire second insulating portion.

Abstract: A testing system for a shaped charge of a perforating gun, the testing system including a housing; a casing assembly located inside the housing; a perforating gun having at least one shaped charge, the perforating gun being located within the casing assembly; a sample material located within the housing, and in direct contact with the casing assembly; a wellbore accumulator in direct contact with the casing assembly and configured to supply a first fluid, at a wellbore pressure, inside the casing assembly; and a formation accumulator in direct contact with the sample material and configured to supply a second fluid, at a formation pressure, on the sample material.

Abstract: A hydraulic time delay system and method in a wellbore tool is disclosed. The system/method includes an actuation mechanism which allows pressure to act on a functional piston in the wellbore tool. The movement of the piston is restrained by a partially or filled reservoir which is allowed to exhaust through a flow restriction element. The restriction element comprises standard metal tubing with a known inner diameter and is cut to an exact length as predicted by fluid dynamic modeling. A time delay and rate of piston movement desired for the downhole tool, between a trigger event such as pressure and a functional event, can be tuned with parameters that include the length and diameter of the tubing, reservoir fluid viscosity and number of tubes in parallel. In another embodiment, a secondary plugging element added to the reservoir controls the rate of piston movement and time delay.

Abstract: A pepper spray gun assembly having a trigger valve for dispensing a non-lethal spray, such as a pepper spray. The assembly includes a storage cylinder for receiving a non-lethal spray charge and a smaller pre-charged charging cylinder for engaging the storage cylinder. The charging cylinder is fluidly coupled to the storage cylinder so as to provide a regulated gas in the head space of the storage cylinder. When the trigger of the trigger valve is operated, the regulated gas will force the charge to be expelled through the nozzle of the trigger valve assembly.

Abstract: A locking device for preventing unauthorized retraction of a telescopic prop is made up of an adjustable clamp which can be fitted round the outer circumference of the prop together with a fastener for tightening the clamp, such as a nut and bolt with anti-tamper heads and a shield to prevent access to the head with a gripping instrument. The device can be placed around the outer circumference of an extended prop adjacent to the collar such that once the clamp is tightened the collar is sandwiched between the locking device and the pin. Alternatively the device can be placed around the outer circumference of the inner tube of the prop adjacent to and abutting the end of the outer tube of the prop in order to prevent unauthorized retraction of the prop.

Abstract: A gas pressure regulator comprising a housing. The housing includes a regulator cap and a regulator body. The regulator cap and the regulator body engage one another through the use of bayonets on one of the regulator cap or the regulator body and pockets on the other of the cap or body. The regulator housing includes a piston having a piston stem in a piston head. The piston stem has a channel and a seat seal on a removed end thereof, the channel for carrying gas to the piston head. The piston head also engages a piston spring. The regulator housing also includes an adjustable seat for receiving a high pressure compressed gas at one end and providing it to the piston stem at a second end. The adjustable seat is adjustable, such that when it is adjusted away from the piston stem, higher cutoff pressure is required than when it is closer.

Abstract: A coin operated game playing machine is operated by a microprocessor so as to permit tournament play among a number of players. Names of top ranking players are displayed and a portion of the playing receipts is allocated to an award fund for distribution to the tournament winners as determined by numerical scoring.

Abstract: A sequence control circuit makes use of a stepping switch to progress the steps of an automatically controlled apparatus. The switch steps as limit switches operate to conclude each stage of the sequence and proving switches, in series with the limit switches, operate to complete sub-circuits and prove the state of the circuit as satisfactory.

Abstract: A combined spoon and toy for providing an incentive to small children to enjoy eating their food. The toy is integrally interposed between the ladle and handle portions of the spoon.
