Title: User interface system for computers
Inventor: AGNARSSON SNORRI
IPC: G06F3/048
Filed: 1993-05-07
Abstract: Abstract of the Disclosure USER INTERFACE SYSTEM FOR COMPUTERS           In accordance with the present invention, user inter-face functions in a computer application program are handled entirely separately from processing functions performed by an application program and the user interface is called from the application processing part of a program.  Whenever the process-ing part of a program requires a user command, an open user interface system (OUIS) is called and begins interacting with the user.  Eventually, the user selects some operation that requires the attention of the processing part of the program.  The OUIS then stops interacting with the user and returns control to the processing part.  When the requested processing is completed, the processing part calls the OUIS again (requests the next opera-tion)  and the OUIS resumes interaction with the user.   The elements defining the interface are arranged in a tree, and user actions typically require updating the interaction status of elements in the user interface.   Updating entire subtrees to update the user interface occurs in two stages:  preupdating and postupdating.  The user interface tree is not considered updated until all elements have been postupdated.  Preupdating flows down the tree, with no element being preupdated until a preupdate has been made of its parent element, if any.  Postupdating flows up the tree, with no element being postupdated until all subelements in its entire subtree has been postupdated.    User interface descriptions are stored in special files, independent of the corresponding program.   The  interface can then be modified without affecting the logical functioning of the application program, and without having to modify the program.     M:\7066\07388\

Title: Variable angular insertion method for lining tubular members
Inventor: MCMILLAN JIM S
IPC: F16L55/16
Filed: 1992-01-21
Abstract: 2100968 9212844 PCTABScor01 A method for lining a tubular member with an elastomeric liner having an outside diameter which is initially greater than the inside diameter of the tubular member. A series of downsizing rollers (37, 57, 59, 61, 63) reduce the outside diameter of the liner a preselected amount. A series of shaping rollers (65, 84, 85) from the downsized liner into an ellipse, thereby allowing the downsized liner to be guided around bends and turns into the interior of the tubular member. After insertion, the liner is allowed to expand to substantially its original outside diameter to secure the liner within the tubular member.

Title: Device for implanting an endoprosthesis
Inventor: GIANOTTI MARC
IPC: A61B17/00
Filed: 1993-11-18
Abstract: Sleeve element (1) is mounted in a lengthwise displaceable fashion on a core element (4). Core element (4) has a pistol butt-shaped handle (8).    Sleeve element (1) has two projections (10, 11) which can only be surrounded by fingers in order to retract sleeve element (1) onto core element (4) to eject an endoprosthesis. Because of its pistol butt-shaped handle (8), greater human force can be used to hold core element (4) than it is possible to use to retract sleeve element (1) by applying fingers to its projections (10, 11). This ensures that when the endoprosthesis is positioned and released by retracting sleeve element (1), there will be no change in the position of core element (4), which would cause an undesired change in the position of the endoprosthesis to be implanted.

Title: Apparatus and method for detecting magnetic electronic article surveillance markers
Inventor: CORDERY ROBERT A
IPC: G08B13/24
Filed: 1993-08-31
Abstract: Method and apparatus for detecting the presence of a magnetic marker in a dual frequency interrogation zone. A dual frequency field is generated to produce an interrogation zone wherein the higher frequency is substantially higher than the lower frequency. The signal generated by the magnetic marker is detected filtered and amplified. Time windows are selected at the expected pulse locations of the signal. The signals detected at the time windows are multiplied by a window function. The product resulting therefrom is averaged to produce a demodulated signal and the presence of a marker in the interrogation zone is determined by detecting the demodulated signal at the lower frequency of the dual frequency interrogation zone.

Title: Inflatable air mattress and pillow incorporating novel variable tension-response internal structural systems
Inventor: GANCY ALAN B
IPC: A47C27/08
Filed: 1994-01-12
Abstract: An inflatable air mattress is designed so as to provide increased comfort during use through the employment of a novel variable tension-response internal structural system. The novel tension-response is achieved through the appropriate parallel-coupling of individual rubber bands. The uninflated mattress occupies minimal storage and shipping space, and is lightweight. An inflatable air pillow, having different userresponse requirements from that of a mattress, employs a novel variable tension-response internal structural system consisting of series-coupled rubber bands. The uninflated pillow occupies minimal storage space. Parallel-coupled rubber band units can be combined in series-coupled units to produce special effects in other applications. The novel tension-response systems can also be constructed into 2- and 3-dimensional embodiments, for mattress, pillow, and other applications.

Title: V.alpha.12.1 t-cell receptor-specific reagents for diagnosing and treating rheumatoid arthritis
Inventor: BRENNER MICHAEL B
IPC: C07K16/00
Filed: 1992-08-27
Abstract: Provided are monoclonal antibodies, fragments, and derivatives thereof reactive with an epitope of the T cell receptor alpha chain variable region, V.alpha.12.1, on human T lymphocytes. The monoclonal antibodies are reactive with approximately 2 % of CD4+ T  lymphocytes and with approximately 5 % of CD8+ T lymphocytes in peripheral blood cells in normal individuals and define a subset of individuals afflicted with an autoimmune disease, especially rheumatoid arthritis, that exhibit increased expression of the V.alpha.12.1 gene on CD8+ peripheral blood T lymphocytes when compared to normal individuals. Also provided are methods for diagnosing, treating, and monitoring the progression of rheumatoid arthritis in a subject using V.alpha.12.1-specific reagents, especially the monoclonal antibodies, fragments, and derivatives of the invention, that bind to a cellular component of T cells and detect V.alpha.12.1 gene usage. Higher levels of assurance in the diagnosis of RA can be made by establishing that the expansion of V.alpha.12.1 gene usage is clonal or oligoclonal and that the V.alpha.12.1 expansion correlates with the occurrence ofthe MHC allele, HLA-DQw2.

Title: Bird feeder
Inventor: AYER S GORDON
IPC: A01K39/01
Filed: 1994-10-02
Abstract: A container for dispensing feed to a number and variety of subjects. Primarily abird feeder. The container comprises a hollow body which can be filled with feed. The body has holes connecting it's exterior to it's interior. Due to the angle, diameter and depth of the holes the feed does not spill out through them but is contained within the central core of the container while at the same time it is accessible from the exterior through the holes. Since no deflectors or other mechanical devices are used to prevent the feed from spilling out the side holes of the container, the flow of feed is smooth and continuous with no opportunity for it to bind or hang up on such devices. The container can be constructed of a single piece or several pieces joined together to form a single piece and can be manufactured out of a single type of material such as wood, plastic, cellulose or ceramic.
Patent CA-2119163-A1 (CA)
Inventor: BRAHMS MARTIN
IPC: H04M15/28
Filed: 1994-03-16
Abstract: A switching device is presented for the transmission of telecommunication signals between a telephone network exchange and at least one subscriber connected thereto, where the exchange is able to transmit metering pulses, in addition to the voice signal. The signals are transmitted as digital signals between the exchange and the subscriber via a two-wire line, Which is connected with the exchange through a hybrid switching unit. To prevent the metering pulses from interfering with the voice signals, a parallel resonant circuit consisting of an inductance and a capacitor is connected to the two-wire system of the hybrid switching unit, and the receiving branch of the hybrid switching unit has an active and a passive filter connected in series. The passive filter is adjusted for the metering pulse frequency, and a filter that is tuned to the passive filter is used as the active filter, which compensates for a decrease in the NF (low frequency) level caused by the passive filter, with a corresponding increase.
