    摘要： Noise-abatement devices are provided for a pneumatic tool that can include a housing having a first end and a second end. An expansion chamber is defined within the expansion chamber. At least one tube is located at least partially within the expansion chamber in which the tube has at least a perforated portion, and an outlet defined therein. The device also includes a port outlet in fluid communication with the expansion chamber in which the port outlet and the outlet are located near the second end of the housing.

    摘要： An apparatus which inhibits the theft of equipment such as personal computers is disclosed. The equipment must have an external wall provided with a specially designed, approximately rectangular slot having preselected dimensions. An attachment mechanism includes a housing for a spindle having a first portion rotatable within the housing, a shaft extending outwardly from the housing, and a crossmember at the end of the shaft having peripheral dimensions closely conforming to the internal dimensions of the slot. An abutment mechanism also emanates from the housing, and is located on opposite sides of the shaft intermediate the housing and the crossmember. The peripheral cross-sectional dimensions of the abutment mechanism and the shaft in combination closely conform to the dimensions of the slot. The length of the shaft from the housing to the crossmember is approximately equal to the thickness of the external wall of equipment. The crossmember is aligned with the abutment mechanism so that the crossmember can be inserted through the slot with the shaft and the abutment mechanism occupying the slot. The spindle is then rotated 90° to misalign the crossmember with the slot, thereby attaching the attachment mechanism rigidly to the external wall. A cable is secured to the housing and to an immovable object so that the equipment cannot be stolen.

    摘要： A progressive cavity pump or motor, particularly suitable for hydrocarbon recovery operations, includes a rotor 20 and a stator 10. Fluid pressure in cavities between the stator and the rotor create torque which rotates the bit. An interior surface of the stator is rigidly secured to the outer housing of the pump stator and defines an interior profile. A substantially uniform thickness elastomeric layer 62 is supported on the outer housing. The pump rotor has an exterior profile which corresponds with the interior profile of the elastomeric layer.
