Abstract: Accessories for firearms. They are designed to reduce the recoil felt by the shooter when a firearm is discharged. The accessories meet this goal by modifying the decay pattern of vibrations set up in the stock when the firearm is discharged. Kick may be further reduced by elastic compression and also by pneumatic compression of air in sealed pockets formed in and by accessory components.

Abstract: Small, effective, lightweight, vibration damping devices for implements which are subject to impact. These devices have a head and a stem and are fabricated from a soft elastomeric material. The stem is capable of oscillating over a 360.degree. span in directions generally normal to the longitudinal axis of the device. The peripheral part of the head can oscillate around its circumference in directions generally paralleling that axis.

Abstract: A cable pulling apparatus includes a winch line on a drum supported on a bed of a vehicle and driven by a motor with a clutch between the motor and drum and a brake associated with the drum. A boom defines a guide for the winch line into a manhole into alignment with an underground conduit and a mandrel is attachable to the winch line. An air gun has one end received into the underground conduit and is expansible into engagement with the conduit and a compressor assembly is attached to the opposite end to propel the mandrel and winch line through the underground conduit. A cable is then attached to the winch line and is drawn through the conduit by driving the drum. A blower and a water pump are also supported on the bed to remove gases and water from the manhole.
