Abstract: The invention relates to an arrangement for employing a drill steel centralizer travelling on a feed beam of a rock drill machine. The drill steel centralizer has a pressure fluid-operated actuator for closing a transfer opening intended for a drill rod during drilling, whereby pressure fluid is fed into the actuator during drilling.

Abstract: An intrusion-resistant apparatus may include a magnetic memory array disposed with an enclosure. The magnetic memory may include a plurality of magnetic memory elements, each adapted to store a binary value only in the presence of a predetermined bias magnetic field having a magnetic field strength and direction within predetermined limits. Means for providing the predetermined bias magnetic field and an encryption/decryption engine may be disposed within the enclosure. An encryption/decryption key may be stored in the magnetic memory array. The encryption/decryption key may be used by the encryption/decryption engine to encrypt and decrypt data.

Abstract: A method includes determining, at a first requesting component of an integrated circuit device, a first key value based on a first set of one or more bits of a first address associated with a first access request of the first requesting component. The method further includes transmitting the first key value from the first requesting component to a resource component of the integrated circuit device. The method also includes determining, at the resource component, an authorization of the first access request based on the first key value and a second set of one or more bits of the first address.

Abstract: An apparatus and a method are provided for selectively accessing digital content carried on a distribution medium such as a physical medium or a broadcast medium. In one embodiment, a plurality of digital content items are encrypted under a plurality of different key management blocks, wherein each key management block is associated with a different set of device keys. The plurality of content items may be provided together on a single distribution medium to devices having assigned device keys, so that devices may selectively access content as determined by the different key management block used to encrypt the various content items and by the device keys assigned to the devices. Depending on the association between the device key and the key management blocks, the decoding device may decode all of the content items, some of the content items, or none of the content items. To provide greater security, each content item may be multiple encrypted using multiple key management blocks per content item.

Abstract: The invention relates to an arrangement for employing a drill steel centralizer (6) travelling on a feed beam (1) of a rock drill machine (2). The drill steel centralizer (6) has a pressure fluid-operated actuator for closing a transfer opening intended for a drill rod (4) during drilling, whereby pressure fluid is fed into the actuator during drilling.

Abstract: A tool is disclosed for driving a slide under a wedge within a slot of an armature or field of a dynamoelectric machine. The tool comprises a frame including a pair of elongated rail members; a force application block located between the rail members; a drive connected to the frame, substantially intermediate opposite ends of the frame; a lead screw threadably engaged at one end with the force application block and connected at an opposite end to the drive such that the drive rotates the lead screw when actuated. Rotation of the lead screw causes axial movement of the force application block. The armature or field includes a core, and this core may have one or more vent slots for facilitating ventilation of the armature or field. A slot plate for locating the tool relative to the slide is present, and a portion of the slot plate extends into one or more vent slots. The slot plate establishes a reaction point for forces applied by the force application block to the stator slide.

Abstract: A post driver has a housing of tubular form extending substantially vertically, and weight telescopically mounted within the housing for movement between an extended position raised above the housing and a lowered position. A strike pad projects from the weight to drive a post into a hole drilled in the ground. A fluid cylinder mounted within the housing extends from a lower part of the housing to the interior of the weight and is operable to raise the weight to its extended position whereby the weight can then fall to a lower position at which its strike pad engages the upper end of the post.

Abstract: Portable robot for carrying out the drilling process in the assembly of aeronautical components which are secured on a support known as a stand. The robot comprises a displaceable platform in order to permit it to be located close to the stand, and an arm, which supports a frame comprising a beam intended to support a drilling head that can be displaced in the three axes.

Abstract: A post driving implement for use with a vehicle, such as a tractor or a skid loader, is disclosed. The post driving implement is comprised of a hammer, a hammer channel, and a hammer cylinder. The hammer travels longitudinally within the hammer channel and is lifted by the hammer cylinder mounted to a closed end of the hammer channel. The hammer cylinder and its associated plumbing is of sufficient size to function as a hydraulic reservoir for the post driving implement, thus eliminating the need for a third hydraulic line to the reservoir on the vehicle and to avoiding need for alteration of the vehicle's reservoir. The post driving implement of the present invention may also include a back plate for mounting the implement to a vehicle. Additionally, the post driving implement may include adjustment mechanisms to vary the positional and angular relationship between the vehicle and the implement.
