Abstract: A drilling bit having two helical withdrawal grooves which extend from the drilling head in the direction toward the insertion or chucking end. The withdrawal grooves have least slope in the vicinity of the drilling head. In the other regions, the withdrawal grooves have a different slope. As a result, no cross-sectional jumps disposed at uniform intervals are provided on the drilling bit, so that transverse oscillations cannot be reinforced by partially constantly or continuously reflected pulses. A considerable reduction in noise is achieved. Furthermore, the central portion of the drilling bit, which is critical during drilling, receives great rigidity.

Abstract: Methodology, and associated circuitry, for encoding and decoding signals utilize combined time-signal path diversity techniques that trade-off bandwidth for autonomy of communications and simplified signal processing, thereby improving reliability. Transmitter (800) processes an incoming data stream by partitioning the stream into contiguous blocks. Each block is encoded into a data frame for transmission over one or more paths comprising the medium interconnecting the transmitter and receiver. Frame encoding is effected by generating an array of pulses distributed in time as well as distributed across the paths. Receiver (100) is generally arranged as a correlation detector in that the receiver only responds to the particular time-signal path pattern for which it is configured. Sensors in energy transfer relation to the one or more paths are positioned at detection points on the paths in correspondence to the time-space pattern of the receiver. The outputs of the sensors are processed to produce a correlation signal at the given frame rate whenever the coded signal corresponding to the receiver configuration is propagating along the paths.

Abstract: An explosive powder charge operated tool for driving nails includes a housing with a muzzle part mounted in and projecting axially outwardly from the housing. By moving the muzzle part rearwardly into the housing, the tool is in the ready-to-fire condition. A magazine is supported at one end within the muzzle part and extends generally radially outwardly from it. A slide in the magazine feeds individual nails in a nail strip into the bore in muzzle part into position to be driven by a piston located within the housing. When all of the nails in the strip have been driven from the tool, one end of the strip projects into the muzzle bore. A stop shoulder on the one end of the strip faces toward an end face on the housing and contacts the end face when the muzzle part is pressed into the housing, preventing the placement of the tool in the ready-to-fire condition.

Title: Method for tunnel driving and device for carrying out the method
IPC: E21D9/06
Filed: 1987-07-15
Granted: 1992-09-02
Abstract: A method of tunnel driving in unstable soils beneath the ground-water level, the face being constantly acted upon by counterpressure from a medium such as water and/or a thixotropic liquid during driving or air during pauses in the driving and being excavated with an excavating tool (6) located in front of the pressure shield (12). The mixture of waste and medium located in the chamber (15) between face and pressure shield (12) is conveyed away, in the course of which the excavation space can be partitioned off in a pressure-tight manner via the pressure shield (12) from the tunnel already driven. When the pressure shield (12) is partitioned off in a pressure-tight manner, the mixture having water and/or thixotropic liquid is mechanically transported into a storage space (16) for the compressed air, which storage space (16) is arranged behind the pressure shield (12), is connected to the chamber (15) via a first opening (19) and is separated in a pressure-tight manner from the tunnel (30). In this storage space (16), the larger parts, such as stones, foreign bodies or the like, are separated out of the mixture, are mechanically comminuted and are fed back to the mixture, the free-flowing mixture being transported away out of the storage space (16) in a pressure-tight manner via a delivery line (25). Instead of the liquid transport, the now fluent solid waste, for the purpose of dry transport, can first of all be transported into the storage space (16) when the same is opened towards the tunnel via a second opening (28) and can be directly transported mechanically from there via the opening (28) into the tunnel (30) without separation of larger parts.   <IMAGE>
