Abstract: A method and an apparatus for testing a self-commutative electric power conversion device, capable of verifying the maximum voltage stress and the maximum current stress in the main circuit of the device by using a testing facility equipped with the power source and the load having relatively small capacities. The pulse shaped turn on and turn off signals are supplied to the switching elements in the self-commutative electric power conversion device, such that a load current having a desired current level for testing flows though an inductive load connected to an AC output side of the self-commutative electric power conversion device having the DC capacitor charged to a desired voltage level for testing. Then, voltage and current waveforms in the self-commutative electric power conversion device are measured, while the pulse shaped turn on and turn off signals are supplied to the switching elements, to verify an operation of the self-commutative electric power conversion device under voltage stress and current stress.

Title: Automatic processing of calls with different communication modes in a telecommunications system
Inventor: YUDKOWSKY MICHAEL ALLEN
IPC: H04M3/51
Filed: 1993-05-12
Granted: 1997-09-16
Abstract: A multimode service system processes calls routed to it by a digital switch in a telecommunications system wherein choices are selectable by the user. Calls are processed by automatically determining the mode of communication utilized by the calling party and communicating with the calling party utilizing the calling party's communication mode to obtain information needed to route the call or implement user selectable features. A reply from the user provides information which determines feature selection or a call routing path. The multimode servicesystem transmits a signal to the telecommunications system which defines the feature or path selection based on the reply from the user.

Title: Remote procedure call pooling with shared memory
Inventor: RUSSELL EDWARD A
IPC: H04L29/06

Granted: 2000-11-07
Abstract: A server for executing operation calls by a client, including a dispatcher, a plurality of worker tasks, and a dispatcher shared memory area and worker control block for each worker task. Each operation call provided from a client is a sequence or one or more remote procedure call requests and each includes a packed buffer containing parameters. The dispatcher receives a buffer directly into the dispatcher shared memory space of the worker task selected to execute the remote procedure call request. sets the semaphore and sends a request acceptance response. The selected worker task unpacks the buffer into its memory space, executes the request, places the results into a packed buffer in its dispatcher shared memory area and sends a remote procedure call to the dispatcher.  The dispatcher executes a remote procedure call to the client and sends the result buffer directly from the shared memory area. The server further includes a dispatcher state save mechanism and the remote procedure call from the worker task includes an identifier of the corresponding saved dispatcher state for the request. The packed buffer associated with a request includes client information and each worker task stores the client information in a worker shared memory space common to the worker tasks and each request of an operation call may be assigned to a different worker task.

Title: Laser assisted demolding of ophthalmic lenses
Inventor: ROSS DENWOOD F
IPC: G02C7/02
Filed: 1993-09-16
Granted: 2001-11-27
Abstract: Described is an apparatus and method for removing a molded ophthalmic lens from between the mold portions in which it is produced. A source of intense electromagnetic radiation, preferably a carbon dioxide (CO2) laser of about 80 Watts at a wavelength of 10.6 µm, is applied to at least one of the mold portions. The exposure of the mold portion to the laser is between one half and one second.      Differential expansion of the heated mold polymer relative to the cooler polymer shifts one surface with respect to the other, and the shear force :breaks the polymerized lens\polymer mold adhesion and assists in the separation of mold portions. The greater the temperature gradient between the surfaces of the mold portions, the greater the shearing force and the easier the mold portions separate.      The heated back mold portion is promptly removed so that very little energy is transferred to the polymer lens, avoiding the possibility of thermal decomposition of the lens.

Abstract: An apparatus for tensioning a belt or cable, reeved about first and second pulleys or sprockets, both mounted for rotation on supports. The apparatus includes a base plate and a post mounted through a closely-sized aperture in the base plate. An arm is mounted to the post at a mounting point at one end of the arm, such that the arm is rotatable about the post with respect to the base plate. An idler sprocket is rotatably attached to the arm at a point spaced apart from the mounting point of the arm, near the opposite end, and positioned so as to be engageable with the belt or chain. Engaging pins are positioned on the arm at a point near the idler sprocket. The base plate has corresponding holes for engaging the engag-ing pins on the arm in a plurality of positions with respect to the base plate. The post is a shoulder bolt which is inserted into the aperture from one side of the base plate and is fastened to the arm on the opposite side of the base plate by a nut threaded onto the end of the shoulder bolt, capturing the arm be-tween the nut and the shoulder. A spring captured between the base plate and the head of the shoulder bolt biases the bolt to slide through the aperture in the base plate, so as to engage the pins in the holes.

Title: Production of fluorocarbon compounds
Inventor: SWANEPOEL JACOBUS
IPC: H05H1/34
Filed: 1994-10-13
Granted: 2006-10-03
Abstract: The invention provides a method and installation for the production of a desired fluorocarbon compound, which includes the steps of providing a high temperature zone; and feeding at least one input material into the high temperature zone to generate a body of hot gas including fluorine-containing species and carbon-containing species. The molar C:F ratio in the body of hot gas is controlled at a selected value between about 0,4 and 2; and the specific enthalpy of the body of hot gas is controlled between about 1kWh/kg and about 10kWh/kg for a time interval, so that a reactive thermal gaseous mixture forms, containing reactive species including reactive fluorine-containing precursors and reactive carbon-containing precursors. Thereafter the reactive thermal mixture is cooled at a cooling rate and to a cooling temperature selected to produce an end product including the desired fluorocarbon compound. The input material is typically a C1-C10 perfluorinated carbon compound of the general formula C n F m in which 0 < n <= 10, and m = 2n, 2n + 2, or 2n -2 where n > 1, for example a gaseous fluorocarbon such as tetrafluoromethane (CF4).

Title: Optical magnifying apparatus
Inventor: FREEMAN ROBIN JOHN
IPC: G02B27/22
Filed: 1993-05-07
Granted: 1998-02-03
Abstract: Optical magnifying apparatus comprises an objective lens (11) from which light is directed to a beam splitting mirror (12). A portion of the light passes through the beam splitting mirror to a first concave mirror (13) and is reflected back via the beam splitting mirror through a viewing lens (5) to a first eye (16) of an observer. The remainder of the light is reflected by the beam splitting mirror to a second concave mirror (17) from which it is reflected back via the beam splitting mirror through the viewing lens to a second eye (19) of the observer. Focussed first and second images (14, 18) of an object (10) are produced respectively on the surfaces of the first and second concave mirrors. The optical axes of the concave mirrors are relatively offset such that the relayed pupils of the mirrors are separated horizontally by a distance approximately equal to the average interpupilary spacing of an observer. The relative inclination of the optical axes of the concave mirrors may be adjustable to enable non-stereoscopic or stereoscopic images of the object to be observed.
