Title: High speed sleever
Inventor: LERNER HERSHEY
IPC: B65C3/16
Filed: 1992-11-06
Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus for placing sleeves on bottles and other objects is disclosed. In particular, a high speed method and apparatus having a plurality of sleeving stations for placing sleeves on bottles is disclosed. Each sleeving station includes a circularly arranged set of relatively movable parallel pins which areoperable to contract or expand. A label transporter deposits a sleeve on the pins when they are contracted. The pins expand to stretch the sleeve. A bottle and the pins are then moved relative to one another to place the bottle inside the stretched sleeve. A gas flow is provided between the bottle and the sleeve to reduce friction. The sleeved bottle is then stripped from the pins. The method occurs without starts and stops by the bottle or the sleeve and is thus capable of very high production rates.

Title: Disposable internal electrode
Inventor: HLINSKY ROBERT L
IPC: A61N1/39
Filed: 1993-01-18
Abstract: DISPOSABLE INTERNAL ELECTRODE ASSEMBLY     Abstract of the Disclosure An internal defibrillation electrode assembly (10) is disclosed including a disposable electrode (12) and a reusable handle (14). The electrode includes an electrode spoon (16), a shaft (18), and a barrier sleeve (20). The handle includes a handle body (58), electrical cable (60), sleeve connector (62), and electrical connector (64). The handle has a dagger-style configuration that makes the electrode assembly easy to use and is further constructed to allow the electrode to be quickly and reliably attached. In that regard, during assembly, a bayonet (32) on the shaft of the electrode is engaged in a bayonet receptacle (68) of the handle. The sleeve is then pulled over the handle to form a barrier between the handle and the environment. After the electrode assembly is used, the sleeve is removed from the handle, the electrode disengaged from the handle, and the electrode disposed of. After attaching a new electrode, the handle is then ready for immediate service. The handle can also be used with a reusable electrode that does not include a barrier sleeve. To that end, the handle is constructed to exhibit a relatively long life when subjected to repeated steam sterilization.            PHYS\4930AP.DOC

Patent CA-2100846-A1 (CA)
Inventor: GUPTA ALOK K
IPC: H04M3/36
Filed: 1993-07-19
Abstract: A unified and systematic approach is taken both to design of a virtual communications network within a carrier's telecommunications network, and to design the screening filters provided in the VCN data base which control the admission of calls to the network. For this purpose, telecommunications traffic information that is relevant for both the design of the VCN architecture as well as for development of the screening filters is aggregated and applied both to a networkdesign tool that is used to generate the customer's virtual network configuration, as well as to a screening filter generator (SFG). The traffic information may include, for example, traffic data contained in network and customer premises equipment call detail records and billing data. In one embodiment, the SFG also receives outputinformation from the network design tool, indicative of the on-net and off-net locations in the VCN, and information from a carrier data base that provides a weighting factor indicative of the incidence of fraudulent calling to different domestic and international destinations.  The SFG is arranged to jointly process the traffic information as well as the fraudulent calling information (together withinformation relating to VCN design parameters, if desired) in order to generate screening filters that can be installed, and thereafter used, in the VCN to determine, on a call by call basis, whether a call made using the VCN is allowed or denied.Advantageously, the screening filters are designed so that they will minimize orreduce the possibility that the VCN will be used to make fraudulent calls.

Inventor: AGRAWAL RAKESH
IPC: C01B21/04
Filed: 1993-09-16
Abstract: The present invention relates an improvement to a cryogenic process for the separation of air which produces at least a nitrogen product and is carried out in a distillation column system having at least one distillation column from which the nitrogen product is produced. The distillation column of the distillation column system must comprise a rectifying section. In the process of the present invention, air is compressed, freed of impurities which will freeze out at cryogenic temperatures, cooled to near its dew point and fractionated in the distillation column system to produce the nitrogen product. The improvement is the operation of the distillation column such that the ratio of downward liquid to upward vapor flow rate (L/V) is no less than 0.65, preferably greater than 0.75, but less than 1.0 in the rectifying section of a distillation column from which the nitrogen product is produced. The flowrates are in moles per unit time.

Title: Method and system for oxidation in a molten bath
Inventor: MCGEEVER CASEY E
IPC: F23G5/00
Filed: 1992-07-06
Abstract: A method and system is disclosed for converting a feed, such as a carbonaceous waste, to dissolved atomic constituents for subsequent oxidation of the dissolved atomic constituents. The feed is injected into a molten bath which, at a sufficient temperature, causes conversion of essentially all of the feed to its atomic constituents, such as atomic carbon. Essentially all of the atomic constituents which are to be oxidized in the molten bath dissolve in the molten bath. An oxidant is injected into the molten bath at a rate sufficient to cause the oxidant to exothermically react with the dissolved atomic constituents to heat at least a portion of the molten bath. The heated portion is thereafter exposed to subsequently injected feed, whereby essentially all of the subsequently injected feed is converted to atomic constituents, and whereby essentially all of the atomic constituents which are to be oxidized in the molten bath dissolve in the molten bath, thereby converting the feed to the dissolved atomic constituents for subsequent oxidation of the dissolved atomic constituents.

Title: Compound Bow Draw Check
Inventor: ARMSTRONG FLOYD W
IPC: F41B5/14
Filed: 1994-02-15
Abstract: A compound bow drawcheck is disclosed for a compound bow which has a bow string connected to a bow cable and a rotatable cable guide over which the bow cable is guided, whereby the cable guide rotates in a predetermined relationship with the bow cable when the bowstring is drawn and between a first position wherein the bow string is not drawn and a second position wherein the bow string is at a desired draw. The draw check includes a detector which detects when the cable guide is in the second position and an indicator which produces asignal when the second position is detected. The detector is either an electrical switch operated by mechanical interaction between a contact strip on the cable guide and electrical contacts on the bow limb carrying the cable guide, an optical sensor detecting a mark on or a hole in the cable guide or a sensor detecting a magnetic strip on the guide. The indicator includes a signal light or LED or a buzzer. The draw check is more accurate than prior art devices and detects underdraw as well as overdraw.
