Title: Controlled fracture method and apparatus for breaking hard compact rock and concrete materials.
Inventor: YOUNG CHAPMAN III
IPC: E21C37/00
Filed: 1991-08-06
Abstract: Hard compact materials, such as rock, concrete, et cetera, are broken by igniting an appropriately designed explosive or propellant charge placed within the hole or carried in a special charge-containing device with a short barrel which is inserted and sealed into a pre-drilled hole of particular geometry. One or more approximately cylindrical holes are drilled into the material to be broken by conventional drilling, such as used in the mining and construction industries. The holes have a relatively short depth to diameter ratio, being in the range of about 2:1 to 6:1, and preferably about 3:1 to 5:1. The holes are percussively drilled with microfractures in and around hole bottoms to provide fracture initiation sites at the hole bottoms so as to provide preferred fracture initiation roughly parallel to a free surface of material being excavated. The explosive or propellant charges may be any of several commercially available explosives or propellants, including standard military and commercial rifle powders and various recently developed liquid propellants. The propellant charges, whether solid or liquid, may be placed and ignited within a charge-containing device, which includes a short barrel inserted into the holes drilled into the material to be broken. The barrel of this device may be further sealed into the holes by a helical shim sealing method.

Abstract: A method for producing a plastic product including an axially extending portion (15), such as a duct or pipe, and a radially extending portion, such as a flange or bracket, is provided. A parison is placed in a first mold cavity defined in a mold and blow molded to form the axially extending potion, and then a movable mold segment (13,14) is moved to a retracted position to define a second mold cavity (18) adjacent to a part of an outer peripheral surface of the axially extending portion thus formed. Then, a second molted plastic material (19) is supplied into the second mold cavity (18) and the movable mold segment (13,14) is again moved to another predetermined position to pressurize the second plastic material to thereby form a radially extending portion. The resulting hollow plastic product is extremely high in structural integrity between the axially (15) and radially extending portions.

Abstract: The invention relates to an idle time communication device in which communication windows are created during the transmission of broadcast data from a center unit (10; 17, 17', 17'') to a user's home device (38), said windows being designed to augment the data transmission function by enabling one-to-one bidirectional communication between said center (10) and said user's home (30). 
     The present invention assumes the prior existence of a communication device for the transmission of broadcast data from said independent center (10) through the telephone network (40) to said user's home (30) and achieves its object of one-to-one bidirectional communication between said center (10) and said user's home (30) through the use of packet communication which is carried out during the idle time on said telephone network (40), which connects the switching system (21) of the local telephone exchange (20) with the telephone in said user's home (30). 
     This makes one-to-one bidirectional communication possible and, in so doing, also enables both the transmission of download data from a control unit (11) to a specified terminal (32) and also the transmission of upload data from a specified terminal (32) to a control unit (11) without confusion between terminals in either case. This enables, for example, (a) a control device (11) to transmit download data to a specified terminal (32) and for the due arrival of said download data to be confirmed at the center (10) by the return upload of data from said terminal (32), (b) the center (10) to receive music requests and instructions in the form of upload data from a terminal (32), and (c) the creation of a protocol that will enable error-free communication to be carried out between control device (11) and terminal (32).

Abstract: A skin-package consists of an underfilm (20) and a covering film (10) of hard transparent film. Perforations (21) are formed in a specific manner in the underfilm and are dimensioned such that the covering film (10) engages in the perforations (21) in the manner of cups in the region of the heat sealing between the covering film (10) and the underfilm (20). 
<??>The perforations can, for example, be of circular construction with a diameter of about 1 mm. 
<??>This results in a blocking effect which improves the adhesion and the mechanical stability of the skin-package and thus guarantees less use of material and easier disposal.

Abstract: A method for the manufacture of salt cores is described. The cores are used for the production of cavities in articles which have been made by a pressure casting technique. The cores are resistant to impregnation and fracture during, for example, the application of pressure during squeeze casting. In particular, the method comprises mixing coarse and fine particle salt powders in the ratio from 50/50 to 70/30 coarse/fine, the coarse powder having a maximum particle size of 250 micrometres, the fine powder having a maximum particle size of 25 micrometres. A lubricant, for example, oleic acid is added, possibly the quantity thereof being in the range 0. 1 to 1.0 wt%. A surfactant, such as a silane, also may be added, possibly the quantity thereof being in the range 0.1 to 1.0 wt%. The mixture is pressed to form a core having a density of at least 1.90 g/cm³; and is sintered at a temperature between 650 o C and 775 o C, for a time in the range 15 minutes to 1 hour.

Abstract: A cache memory (16,46,66,110) only stores writes to a data line and not reads. The cache memory (16,46,66,110) does not respond to a read hit directly. Instead, all reads from its associated processor (12,42,62,102) are guided to main memory (20,50,70,120) which supplies the data line corresponding to the read request. If the cache memory (16,46,66,110) has locally stored data corresponding to all or part of the data line read which has been modified, then the modified data is merged with the data from the main memory (20,50,70,120) and sent to the associated processor (12,42,62,102).

Abstract: A transluminal grafting system for grafting a prosthesis (1,12) to the wall (2) of a lumen includes a tubular graft (1) provided with spring assemblies (12) and anchoring barbs (205). The prosthesis is mounted on an apertured tubular carrier (21) and a central control means (26) is inserted into the bore of the apertured carrier. Mooring loops (36) are attached to the prosthesis, pass through the apertures (29) of the tubular carrier, and engage the central control means. An introducer sheath covers the system for smooth insertion into a lumen. When the graft has been positioned, the central control means maintains the axial position of the prosthesis. When the introducer sheath (4) is pulled, the prosthesis is exposed and the spring assemblies return to an expanded state and anchor the graft against the internal wall of the lumen.

Accommodated therein is a fresh water container (2), a ground coffee container (3), a residual water container (4), a grinding unit (5) and control and heating members, denoted jointly by reference numeral (6), for heating and feeding fresh water from the fresh water container to a brewing device (8). The latter is attached to a further housing (19) via spring bars (41) which engage in notches (42). Said further housing comprises a drive motor (15) and a gear mechanism (18) from which a drive axle (20), penetrating the wall of the further housing (19) and producing an operative connection with the brewing device (8), protrudes into a drive spindle of the latter. The brewing device (8) constitutes a first partial module, the further housing (19) with the drive motor (15), the gear mechanism (18) and the drive axle (20) constitutes a second partial module (17) of a first module (16) which can be removed from the machine. In the removed state shown, the operability of the brewing device (8), which comprises all the parts subjected to soiling by coffee powder or coffee, can be checked by the electrical energy for driving the motor, which is still operatively connected to the brewing device (8), being able to be supplied via a socket (21). To clean the brewing device (8), the latter can be lifted off from the second partial module (17) after the removably arranged liquid pipes (29, 30) have been separated. By virtue of the modular construction, cleaning, maintenance, repair and testing work can be carried out easily. <IMAGE>
