Title: Arrangement for fixing an elevator rope
Inventor: HAKALA HARRI
IPC: B66B11/04
Filed: 1995-09-27
Granted: 2000-05-23
Abstract: According to the invention, at least one end of the elevator ropes (8) is fixed to a guide rail (4, 7) of the elevator. According to an embodiment of the invention, the whole elevator is so suspended by its ropes (8) that all vertical forces are transmitted by the guide rails (4...7) to the bottom (27) of the shaft (1). The invention provides the advantages that the elevator is easy to install and that the vertical forces are transmitted by the guide rails (4...7) to the bottom (27) of the shaft (1), permitting a lighter construction of shaft walls.
Patent CA-2203643-C (CA)
Inventor: FRIEDRICH RALPH
IPC: F16L47/00
Filed: 1995-10-24
Granted: 2000-04-25
Abstract: A pipe joint for fiber reinforced composite pipe (10, 13) has internal and external matching tapers (11, 14) with a low taper angle. A half round helical groove (16) is formed in each of the internal and external tapers (11, 14) for receiving several turns of a ductile key (17). Deformation of the key (17) in shear redistributes longitudinal loads along the length of the pipe joint. The outer member of the pipe joint (13) has a high stiffness so that internal pressure in the pipe presses the tapered surfaces (11, 14) together so that the resulting friction enhances the longitudinal load carrying capability of the joint. High external stiffness may be provided by winding the external moiety of the joint with high modulus of elasticity fiber.

Abstract: A vehicle suspension system having a pair of hanger brackets (5) and a pair of beams (15). A first end of each beam is attached, via a bushing sleeve to each hanger bracket, and an axle (19) is rigidly attached to the second end of each beam. Each beam is manufactured from a plurality of layers of laminate material which extend circumferentially around the axle and the bushing sleeve (30). An adhesive layer extends between the bushing sleeve and axle, and the layers of laminated material, for securing the bushing sleeve and axle to the beam. Inasmuch as the laminate material and adhesive have relatively low modulus o f elasticity, these materials flex in response to movement of the axle, thereby assuring that the connection between the laminate beam (15 ) and the axle (19) remains stable, even as the axle moves in response to forces acting thereon. In another embodiment of the invention, each beam (47) is integrally formed with an air spring piston (48). In another embodiment of the invention, a parallelogram suspension is provided with a pair of parallel and spaced-apart control arms (62) manufactured of laminate material. Alternatively, the control arms of t he parallelogram-type suspension may be integrally formed with a stabilizer bar (68) extending therebetween. In alternative embodiments, a pair of air spring pistons (48) may be mounted on the stabilizer bar (68), substantially reducing the weight and cost associated with the manufacture and operation of air spring suspension systems.

Granted: 2004-04-06
Abstract: A method and apparatus to provide access to a dispatch system is disclosed. A  communications manager (40) grants an exclusive system talker privilege to one remote unit (10) in the system at a time. After a remote unit (10) requests and is designated as the exclusive system talker, no other remote unit (20, 22) may transmit for a first pre-determined amount of time. After the first pre-determined time has elapsed, any other remote unit (20, 22) may request the exclusive system talker privilege and become the exclusive system talker. The exclusive system talker privilege is revoked by the communications manager (40) to any remote unit who retains the exclusive system talker privilege for more than a second pre-determined amount of time. The exclusive system talker privilege is also revoked upon the release of a push-to-talk button on a remote unit (10). Furthermore, a base station (44) in communication with a remote unit (10) designated as the exclusive system talker will generate a surrogate relinquishment request to the communications manager (40) if the exclusive system talker travels outside the coverage area of the system, loses power, or is destroyed.

IPC: G06F12/00
Filed: 1998-10-28
Granted: 2005-02-15
Abstract: A system, method, and computer readable-medium for performing operations associated with browser requests are provided. The system includes a plurality of dispatchers coupled to a plurality of web listeners. Each of the dispatchers receives from a corresponding web listener browser requests received by the corresponding web listener. The dispatchers are configured to send messages through an inter-machine communication mechanism to cartridge instances. The messages cause the cartridge instances to perform the operations associated with the browser requests. Each cartridge instances includes a cartridge execution engine and a cartridge. The cartridge execution engine handles all inter-machine communication with the dispatchers, and passes the requests to the Lamiides by making calls into the application programming interface of the cartridge. Consequently, cartridges are isolated from the complexities of inter-machine communication, and may therefore be used in a highly distributed system without being distribution-aware.
