Patent EP-0354760-A2 (EP)
Inventor: STANKUS JOHN C
IPC: E21D20/02
Filed: 1989-08-08
Abstract: A roof anchor (10) for supporting an underground mine roof (12) has an elongated shaft (16) with a head (20) formed at one end. The head (20) supports a washer (23) and a roof supporting plate (24) that surrounds the mouth of a blind bore (14) formed upwardly into the roof. A resin capsule (32) is positioned within the blind bore (14) above the roof anchor (10). The shaft (16) of the roof anchor has an adjustably securable annular washer (26) surrounding the shaft. The annular washer (26) is fixed in a position so that when the resin capsule (32) is ruptured to release the resin to bind the roof anchor (10) within the bore hole, the resin completely fills the bore hole from the blind end of the bore to the rigid annular washer (26) fixed to the shaft of the roof anchor. By making the position of the annular washer axially adjustable, the roof anchor may be utilized with varying amounts of resin as conditions at the mine site require and still cause the resin to be subjected to a compressive force within the bore hole in the space between the end of the bore hole and the annular washer.

Abstract: A clutch plate assembly (24) for a vehicle driveline includes a spring damping mechanism disposed in parallel with a viscous shear damper mechanism (30) for damping spring recoil. The spring damping mechanism includes a set of pairs of relatively high rate helical compression springs (34,36) for transmitting torque and attenuating torsionals when a transmission input shaft (22) is connected to a load and a set of relatively low rate helical compression springs (38) connected in series with the high rate springs (34,36) for attenuating torsionals when the shaft (22) is not connected to a load. The viscous damper mechanism includes an annular housing (48) having first and second radially extending sidewalls (52,54) defining a compartment (48a) having a clutch assembly (50) disposed therein for viscous clutching coaction via a viscous shear oil. An inner member (58) of the clutch assembly (50) includes a dynamic seal assembly (66 or 72) molded integral therewith for sealing the inner extent of the compartment (48a). The inner extent of the housing includes a plurality of fasteners (56e) structurally interconnecting the inner extent of the sidewalls (52,54) to prevent relative axial movement of the sidewalls due to centrifugal effects. The housing sidewalls (52,54), and the clutch and seal assemblies are formed to facilitate a method for readily assembling and accurately filling the damper with viscous shear oil.

Abstract: A method and an apparatus are provided for aligning a belt-like member, wherein a belt-like member (15b) prepared by cutting a raw material (15) of the belt-like member on a conveyor (12) at two locations with inclined cuts, is conveyed by the conveyor, wrapped around a cylindrical drum (1) and stuck to the drum. The inclination angle of the line of cut at the leading end of the belt-like member is measured at the time of cutting, the inclination angle of the line of cut at the trailing end is measured at the time of cutting, and by comparing the inclination of the cut line at the trailing end with the inclination angle at the leading end, an amount of correction for the inclination angle is calculated. After cutting at the trailing end, the trailing end portion is attracted and held by an attracting device (120), and by rotating this attracting device on the basis of the aforementioned amount of correction for the inclination angle, the inclination angle of the line of cut at the trailing end is corrected so as to coincide with the inclination angle of the cut line at the leading end. While maintaining this corrected condition, the belt-­like member (15b) is wrapped around the cylindrical drum (1) for sticking the ends together.

Abstract: A system for removal of asbestos material comprises a pair of collection and discharge units (3,5). Each unit includes a housing (7), a hopper (9) mounted to the housing (7), and a slide gate valve (5) or valves for selectively sealing and opening the associated hopper (9). A vacuum line (115) and a collector tube (119) are connected to each hopper (9). Suitable valves are installed in the vacuum lines (115) and collector tubes (119). By controlling the slide gate valves (51) and the vacuum line (115) and collector tube valves (133,135), a vacuum can be created in the hoppers (9) alternately to draw material into a selected hopper (9). With the vacuum dissipated from a hopper (9), the sliding gate valve (51) is operable to discharge material from that hopper (9) while the other hopper (9) is being filled, thereby enabling material to be continuously removed from the source (120).

Abstract: The invention relates to an electronically controlled wheelchair, having electric motors to drive the wheelchair wheels, electrically operable parking brakes for the wheelchair wheels, an electronic control circuit for the drive electric motors and a manually operable actuating switch for controlling the electronic control circuit, including an interruption in the power supply to the drive electric motors and activation of the parking brakes in the neutral position of the actuating switch. In order to be able to terminate the occurrence of uncontrollable wheelchair operating modes at short notice, as can be caused, for example, by external electromagnetic alternating fields in the control circuit, the invention provides for a neutral position detector, which detects the neutral position of the manually operable actuating switch and, when the actuating switch is in the neutral position, emits a motor switching signal which interrupts the power supply to the drive electric motors, bypassing the electronic control circuit. These advantages are ensured by a neutral position detector which differs in its various embodiments from those previously known in that it is constructed in principle using few and/or relatively low-wear parts. This increases the reliability and permits the detection of a relatively narrow neutral position region.

Abstract: In an FDDI token ring network, a repeat filter that treats FDDI Set and Reset symbols occurring in a frame prior to an End Delimiter symbol as a violation and does not repeat these symbols onto the FDDI ring. In addition to the three states described in the FDDI repeat filter standard for a byte-wide implementation, a repeat filter in accordance with the present invention includes a fourth END state. The presence of this END state allows the REPEAT state to be resticted such that it treats bytes within a frame with either symbol of the byte being either a Set or Reset symbol as a violation and a Halt byte is transmitted onto the ring; the repeat filter then enters the Halt state. In addition, the repeat filter is also responsive to "mixed" bytes that consist of an FDDI data symbol and an FDDI control symbol. If the mixed byte is a data symbol followed by an End Delimiter symbol, then the repeat filter transmits an FDDI zero symbol followed by an End Delimiter symbol and enters the END state; if the mixed byte consists of a data symbol followed by an Idle symbol, then the repeat filter transmits an Idle byte and enters the Idle state.

Abstract: A menu bypass system for an IBM 3270 type of display system. An IBM 3270 type display system includes a display terminal, a communications controller and a host computer running a host application which controls the terminal. The host computer and terminal communication use a protocol which allows the host to transmit data to and read data from the terminal at any time. After a transmission from the terminal to the host, the terminal is normally locked from further transmission until the host application responds. The menu bypass system allows transmission of request units generated by attention identifiers. These request units are stored in a queue and transmitted to the host one at a time in response to host commands. For certain host commands, such as erase/write, a previous write transmission from the controller to the terminal is aborted.

Abstract: Translucent detergent bar contains 30 to 45wt% soap, 5 to 15wt% monohydric alcohol and 5 to 15wt% dihydric alcohol whose molecule contains at least one alkylene group with at least three carbon atoms and water. Optional ingredients include up to 10wt% non-soap detergent and polyhydric alcohols, sugars and polyalkylene glycols. The combination of monohydric and dihydric alcohols promotes translucency while avoiding disadvantages observed with either of them alone. The bars can be made by forming a melt of the component ingredients, casting the melt into moulds and allowing it to set.
