Abstract: A method of volume screening signalling messages in a communications signalling system, in which control orders from a centralized control are distributed so as to provide equitable volume screening of selected signalling messages being sent over each available communications link of a plurality of links within link sets that interconnect signal transfer points (STPs) of the system. This is achieved by dynamically apportioning the acceptance rate of the selected signalling messages from each available link, in the same proportion as that of the total signalling messages being sent over that available link.

Abstract: A tailgate for preventing cattle from backing up while in a guide chute is described. The tail gate comprises a tube, angle brackets and a gate section. The angle brackets are arranged to be fitted into the tube such that the angle brackets can be attached to horizontal or vertical surfaces. The gate section is arranged to pivot about the tube from one side of the tube only so that cattle may pass freely from one side of the tail gate but are prevented from passing from the opposite side. As a result of this arrangement, cattle contacting the gate from the opposite side of the tail gate will reflexively remain in place. This in turn prevents the cattle from backing up and speeds up the flow of cattle through the chute. The tail gate is arranged to be fitted into chutes of various widths at any point along the chute fitting and the height of the gate section can be varied for use with animals ofdifferent sizes.

Title: Method and apparatus for data network call processing
Inventor: AMIN UMESH J
IPC: H04W88/16
Filed: 1997-11-10
Granted: 2002-01-01
Abstract: A method and apparatus for processing data network communication calls. A calling party device sends a call initiation request to a packet data network node from a computer. The request includes identifications of alternate calling party devices along with respective priority for each device. The packet data network node determines the highest priority called party device which is available and initiates communication between the calling party device and the called party device. The called party device may be, for example, a computer, a landline telephone, a wireless mobile station, or a pager. If the called party device is a telephone, the packet data network node establishes a data network connection with the calling party computer and a telephone connection with the called party telephone and performs the required conversions to allow communication between the calling party computer and the called party telephone.

Abstract: A sheet dispensing mechanism employs an open bottom sheet dispenser (44) positioned beside a molding device (14), molding articles (34) which are cyclically ejected and driven vertically downwardly along an article ejection path (T), with the bottom sheet (40) shingling out against an oblique baffle (112A). A pair of rotatable indexing rollers (88) with a high coefficient friction member (89) on the periphery of each roller penetrate the open bottom of the dispenser to press the single sheets against the baffle, thereby allowing the indexing rollers to frictionally drive only the end sheet in the direction of the path. A spring biased articulated nip roller assembly (99) downstream of the dispenser accelerates the indexed sheet to intersect the ejection path of the article simultaneously with ejection of the article. A proximity switch senses the arrival of the food portion at the article ejection station to initiate one cycle rotation of the indexing rollers to index the bottom-most sheet of the stack.

Abstract: A pair of wing assemblies for attachment to a snow thrower or snow blower employing an impeller within a housing and having a forward opening therein to facilitate the feeding of snow to the impeller. The wing assemblies are each adjustably pivotally attached to a horizontal rack provided on each side of the housing. The position of each wing assembly is determined by the position of an arm connecting the back of the wing with the rack. In a first operative position, suitable for use after a light snowfall, the wings are positioned so as to diverge forwardly and thus increase the catchment area of the snow to be fed to the impeller, thereby improving the efficiency of operation of the snow thrower. In a second operative position, the wings are positioned so as to diverge rearwardly so as to push snow away from the snow thrower and increase the width of the path cleared. An inoperative third position with the wings folded laterally in front of the snow thrower permits compact storage of the snow thrower without having to remove the wing assemblies.

Abstract: A system and method are provided for executing a request from a client application. Unlike conventional networks in which a client application transmits several data access transactions to several server applications, the client application of these preferred embodiments merely sends a single request to a gateway application, which converts the request into appropriate data access transactions. The preferred embodiments provide the advantage of allowing a client application to communicate with a plurality of server applications without knowing the server application's format or syntax requirements. Further, unlike environments in which a client application compiles data received from each contacted server application, in the environment of the preferred embodiments, the client application is presented with a single integrated response.

Abstract: An anaesthesia control system and a method of calculating an index representative of the depth of anaesthesia is disclosed. The method comprises subjecting a patient to a repetitive audio stimulus and monitoring auditory evoked potentials (AEP) produced by the patient and then recording these auditory evoked potentials using EEG recording means and providing a signal corresponding to the coarseness of the monitored AEP signal and using this signal as an index indicative of anaesthetic depth. The raw AEP signal is divided into a series of sweeps and each sweep is synchronised with the repetitive audio stimulus and sweeps are recorded in sequence to produce a time averaged sweep from which the anaesthetic index is calculated. The anaesthetic index is constantly updated by repeatedly conducting a successive series of sweeps. The system and index signal can be used as part of an anaesthesia control system for regulating the supply of anaesthetic to the patient to maintain the anaesthetic index at a predetermined level.

Abstract: A seal (12) that is particularly suitable for use in a gas spring (14) and other high pressure hydraulic and pneumatic sealing applications and that minimizes the leakage of relatively high pressure gas and lubricating oil from the rod end of the gas spring or other applications. The generally annular seal body (62) includes a number of convex sealing lobes (74, 76, 78, 82, 84) on its radially inwardly and outwardly facing surfaces. All of the sealing lobes have a predetermined radius and project radially beyond the plane of their respective surfaces. The axial facing surfaces (68, 72) of the seal body (62) are generally flat or non-concave. The seal also includes a wiper insert (94) secured in a recess (92) in one comer of the radially inwardly facing surface (64) of the seal body (62). When the seal body (62) is compressed between the relatively movable, annularly spaced piston rod (32) and cylinder (16), the compression induced stress in the seal causes the seal body (52) and insert (94) to form an effective gas and oil seal.
