Abstract: Receptacle locking devices are disclosed. A receptacle locking device having a contact arm and a pivoting feature can be pivoted from a first, unlocked position to a second, locked position, wherein the contact arm prevents opening of the receptacle door when the locking device is in the second, locked position.

Abstract: Systems, devices and methods for storage, delivery, receipt, and/or other handling of an item in an electronically controllable storage receptacle are disclosed. The disclosure provides features for keyless access to the storage receptacle by use of user access information, such as a PIN or bar code. Further, features are disclosed for receiving and/or transmitting data related to the recipient and the item to facilitate the various handling actions of the item.

Abstract: A method of supporting a substrate includes inserting a rock bolt into a hole and using the rock bolt to form a groove in a wall of the hole when the rock bolt is inserted therein. The rock bolt is caused to interact with the groove in such a way that the rock bolt is secured in the hole at least in part by the interaction.

Abstract: A Centralizer based Survey and Navigation (CSN) device designed to provide borehole or passageway position information. The CSN device can include one or more displacement sensors, centralizers, an odometry sensor, a borehole initialization system, and navigation algorithm implementing processor(s). Also, methods of using the CSN device for in-hole survey and navigation.

Abstract: A helical drag bit provided with spirally/helically positioned cutting arms. The arms can create a spiral trench geometry in the sidewall of a predrilled pilot hole. The cutting arms can terminate in scoring cutting blades. The helical drag bit can be incorporated into a system and method for measuring geo-tech characteristics. The helical drag bit can be used in a system and method for improving the holding capacity of rock bolts and similar devices for use in the mining industry or in any circumstances where a particulate substrate may benefit from support. Novel rock bolts having new structures can be used with this improved hole geometry or may form such improved hole geometry.

Abstract: The invention relates to a brake system for railway equipment. More particularly, the invention relates to brake devices and systems for pneumatically and manually actuating such devices on railroad train cars such as freight cars. The brake system can be integrated into modern trains without interfering with existing air brake systems. The brake system can be remotely operated, locally pneumatically operated and/or locally manually operated. Monitoring equipment for determining the status of the brakes from remote and local positions may also be provided. The invention may be configured to fit within the envelope of prior art handbrake systems.

Abstract: A safety device may be used to provide separation in the event of a side impact collision. The device may be used in a utility pole guy wire system, interposed between the guy wire and the ground anchor. The device operates in bending. A lateral force of sufficient magnitude applied to the device by the errant vehicle causes a rod within the device to break in tension, even though the tensile strength of the rod may be greater than that of the guy wire. In operation, certain massive portions of the device are tied safely to the ground, while other portions are pulled over the moving vehicle by the tension of the guy wire. The invention may be designed to tolerate axial loads, but to fail reliably when a side force exceeds a desired threshold. When installed in series with a utility pole guy wire, the invention will withstand all normal tensile and incidental loads, and will release when subjected to a high side force as from an automobile impact.

Abstract: A drill bit is provided for drilling holes in hard, reinforced material, including reinforced concrete. According to one aspect of the invention, wear-resistant inserts are provided in a cross-shaped pattern. The inserts ensure that the entire bottom surface of the drilled hole is engaged during each drill bit revolution. The inserts may be secured in pockets or slots. Fluid entry ports may be located between the inserts for efficient handling of drilling fluid and removal of drilled material, without impairing the structural integrity of the drill bit. According to another aspect of the invention, the drilling surface is separated into two or more stages to increase drilling efficiency, especially through composite material such as reinforced concrete.
