Filed: 1999-04-23
Abstract: A cutting assembly for a motor chainsaw has a guide bar with peripheral guide groove and guide surfaces. A saw chain circulates in the guide groove in a longitudinal direction of the guide bar. The saw chain has chain members such as centrally arranged drive members and connectors, laterally connecting the drive members.      Some of the connectors and some of the drive members are embodied as cutters arranged altematingly on opposite sides of the saw chain. Rivets connect the chain members pivotably to one another and extend transversely to the circulating direction. The drive members engage the guide groove arid the connectors are slidably supported on the guide surfaces. Each cutter has a base, a support stay connected to the base, and a cutting tooth connected to the support stay. The cutting tooth has a laterally projecting roof portion having a leading end in the circulating direction with a roof cutting edge. The support stay has a first portion positioned in a central plane defined by the drive members, and the roof portion projects in a direction of the cutting plane of the saw chain in which direction the base also faces. The roof portion has an outer angled edge extending in the circulating direction parallel to the base. The angled edge has a lateral cutting edge positioned in front of the roof cutting edge in the circulating direction.

Title: Controlled foam injection method and means for fragmentation of hard compact rock and concrete
Inventor: YOUNG CHAPMAN III
IPC: E21C37/12
Filed: 1999-06-21
Abstract: Breaking hard compact materials, such as rock and concrete, is based upon a controlled-fracturing process. A high-pressure foam is used to pressurize a predrilled hole of appropriate geometry. The high-pressure foam is delivered to the bottom of the drilled hole by a barrel inserted into the hole. The barrel includes a seal near the bottom of the hole. By restricting and controlling the pressure of the high-pressure foam to the bottom of the hole, a controlled fracturing is achieved which results in the fracturing and removing of a large volume of material at a low expenditure of energy. The foam-injection method produces almost no fly rock or airblast. The foam-injection method may be used to fracture, remove and/or excavate any hard material such as rock or concrete. The method may be used in either dry or water filled holes and the holes may be in any orientation. The foam injection apparatus is carried on a boom mounted on a carrier. An indexing mechanism allows both a drill and a foam injection apparatus to be used on the same boom for drilling and subsequent high-pressure foam injection.

Title: Method and apparatus for a sectored cell of a cellular radio communications system
Inventor: BEVAN DAVID DAMIAN NICHOLAS
IPC: H04B7/005
Filed: 1999-11-16
Abstract: A nine-sectored cell (20) of a cellular radio communications system has three base transceiver stations (BTSs) colocated at its cell site (26). Each BTS is substantially independently coupled to a remote base station controller (BSC). Each BTS handles communications with subscriber units within a respective coverage area including three mutually-adjacent sectors (e.g. a1, b1, c1). When a subscriber unit moves between the coverage areas of different BTSs, a soft handoff is controlled by the BSC. When a subscriber unit moves between two sectors in the same coverage area, a softer handoff is implemented by the respective BTS.

Title: Method for operating base station to solve speech disable state based on inter-speech sphere movement of mobile station in enlarging speech radius limited in timing in code division multiple access mobile communication system
Inventor: CHUNG CHAE HUN
IPC: H04W36/38
Filed: 2000-01-06
Abstract: A method for operating a base station to solve a speech disable state based on the inter-speech sphere movement of a mobile station in enlarging a speech radius limited in timing in a CDMA mobile communication system. In a base station where a speech radius wider than that limited by a modem ASIC is partitioned by a predetermined radius unit into a plurality of speech spheres for the enlargement of the limited speech radius and channel elements are assigned to the partitioned speech spheresfor transmission/reception of channels, a handoff operation is performed from an arbitrary channel element in the base station to a channel element assigned to a different speech sphere when a mobile station moves beyond an initial speech sphere during conversation with the arbitrary channel element. At this time, a reverse traffic channel is demodulated and remains at a standby state. Therefore, if the mobile station moves beyond the initial speech sphere above the predetermined radius unit, the demodulated reverse traffic channel is selected and utilized by the channel element assigned to the different speech sphere. This has the effect of preventing a speech disable state based on the inter-speech sphere movement of the mobile station.

Title: Precast reinforced concrete railway crossing slab
Inventor: MILLER PAUL B
IPC: E01C5/10
Filed: 1998-07-20
Abstract: The present invention discloses a precast railway crossing slab (10) adapted to extend transversely across the surface of conventional railway ties, with slots or gaps dimensioned and disposed to receive a pair of railway rails therethrough. The crossing slab includes a post-tensioning system in which metal cable strands or tendons (42) are sheathed within plastic tubes and are positioned in the slab mold frame prior to pouring of concrete. Tendon anchors are also disposed in the slab mold frame prior to pouring. After the concrete hardens, a hydraulic jack is used to tension and anchor the tendons (42) in a stressed condition, thus providing reinforcement to the slab. The railway crossing slab of the present invention may be utilized with or without surface or edge metal plating. Flange way fillers which typically comprise rubber strips extending between the sidewalls of the metal rail and the concrete slab may optionally be employed. The slab may be formed integrally with grooves to receive the rails, or alternatively may take the form of three separate slabs (12, 14, 16) provided with screw holes (18) for securement to conventional wooden or concrete railway ties.

Title: Process for manufacturing pipes
Inventor: NEILL DAVID
IPC: B21J5/06
Filed: 2000-02-28
Abstract: A process for producing clad pipe comprises forming a hollow body (S10) of base material, bonding a cladding material metallurgically to the base material. (S12) to form a composite body and subsequently extruding the composite body to form a pipe. This process allows the metallurgical bond to be validated using non-destructive methods prior to extrusion. Any areas that arc unbonded will be detected, thereby reducing wastage. Moreover, because the metallurgical bond is achieved prior to extrusion, the cladding thickness is controlled during the extrusion process, avoiding migration of the clad material into the base material by disproportionate amounts.
