Title: Positive displacement machine
Inventor: BECHER ULRICH
IPC: F04C18/16
Filed: 1999-04-01
Granted: 2008-02-19
Abstract: The invention relates to a positive displacement machine which is especially used as a pump and comprises a work chamber (2) formed in a housing (1). Said work chamber is delimited by two facing walls (3, 4) and by a casing (5), and can be accessed via an inlet (6) and an outlet (7) for a work medium. The invention comprises at least one rotor (8) which is arranged in the housing such that it can move and which subdivides the work chamber. A guiding transmission (10) for controlling the rotor is connected to a drive device (11) located outside of the work chamber. The aim of the invention is to provide a positive displacement machine which can be produced with fewer expenditures and with a lower weight compared to known positive displaced machines of this type. In addition, the aim of the invention is to provide a positive displacement machine which can be operated especially without special lubricants for the bearings. To this end, the rotor or rotors is/are at least partially mounted inside the work chamber, the bearing or bearings (16, 17) arranged inside the work chamber can be accessed by the work medium, and the bearing or bearings is/are produced as antifriction bearings, whereby a lubricant-free operation of the positive displacement machine is possible. As a result, the work medium is virtually prevented from being contaminated with lubricant.

Title: Artificial lens including a multifocal lens system having eccentric axis and method
Inventor: HERRICK ROBERT S
IPC: A61F2/16
Filed: 1998-04-30
Granted: 2008-11-18
Abstract: An artificial lens adapted for use in an eye having a macula is shown. The artificial lens is adapted to be affixed to an eye and has a multifocal optical lens system wherein the principal axis of each lens is eccentric to each other for directing light rays from each image of each lens of the multifocal optical lens system onto a macula of an eye. In the preferred embodiment, the artificial lens includes a first lens having a predetermined diopter power for receiving light rays from a near object and a prism having a preselected diopter power. The prism is positioned on a selected surface of the first lens for directing paracentral light rays from a near object onto a macula of an eye and central light rays to a location superior of the macula. The artificial lens includes a second lens having a predetermined diopter power positioned eccentrically inferior of said first lens for receiving light rays from a distant object and a second prism having a preselected diopter power. The second prism is positioned on a selected surface of the second lens for directing paracentral light rays from a distant object onto a macula of an eye and central light rays to a location inferior of the macula. A method for producing multiple images of an object for an eye is also shown.

Title: Binder with expandable outside pocket
Inventor: MOOR MARC L
IPC: A45C7/00
Filed: 2000-03-17
Granted: 2005-07-05
Abstract: An expandable outside pocket (60) is provided on one panel of a binder (50).  This pocket includes a releasable closure to control expansion of the pocket. In one configuration, the outside pocket includes a zippered gusset (70), where the zipper (72) can be closed to prevent expansion of the pocket capacity. The gusset (70) and zipper (72) configuration enables the pocket to be expanded when it is desired to increase the size of the pocket in order to accommodate larger items such as books, but also enables the gusset to be held in a non-extendable position when the pocket does not need to be expanded, such as when the pocket is only used to carry papers or slim folders. A second zipper (78) is preferably also provided in order to control access to the pocket. In another configuration, the outside pocket includes gussets along its sides which facilitate expansion of the pocket, and a single zipper provides access to the pocket interior when unzipped and also enables the pocket to expand when unzipped. The pocket can be expanded to provide simple access to the pocket interior, permitting convenient perusal of papers within the pocket without removal of the papers.

Title: Separable electrical connector assembly
Inventor: BORGSTROM ALAN D
IPC: H01R24/02
Filed: 2003-06-23
Granted: 2008-11-18
Abstract: Separable electrical connectors which are modified to reduce the probability of flashover upon disassembly operation of a bushing insert from a power cable elbow connector. The bushing insert is provided with vents to vent a cavity formed between the elbow cuff and the transition shoulder portion of the bushing insert with ambient air to avoid a decrease in pressure within the connection region and avoid a decrease in the dielectric strength of the air therein thus preventing flashover. The vents can be provided directly on the transition shoulder portion of the insert, an elbow seating indicator band or on a bushing insert interface shell. Additionally, the band and the shell may be formed of a bright contrasting color which serves to indicate whether the loadbreak connector is improperly assembled. The shell further reduces friction upon assembly of the connector.
