Abstract: The present invention provides an oral dosage form comprising a first composition and a second composition. The first composition comprises an effective amount of a therapeutic agent and the second composition comprises an effective amount of an adverse-effect agent. The adverse-effect agent is covered with a coating that is substantially insoluble in the gastrointestinal tract. In one embodiment, the adverse-effect agent is coated with an outer base-soluble layer and an inner acid-soluble layer. The therapeutic agent can be uncoated or can be coated with a coating having an outer acid-soluble layer and an inner base-soluble layer. The dosage form discourages administration of the therapeutic agent by other than oral administration.

Title: Preventing unauthorized hoistway access
Inventor: KOCHER JOHANNES
IPC: B66B13/16
Filed: 2004-03-03
Granted: 2011-09-20
Abstract: The invention relates to a means and method of preventing unauthorized access of personnel into the hoistway of an elevator system. In particular the invention provides a security device (14) for mounting in the vicinity of an auxiliary release mechanism of a sanding door to prevent actuation of the auxiliary release mechanism during normal operating conditions. The security device (14) comprises an energization circuit which, in use, is responsive to changes in operating conditions of the elevator system and may also include an obstruction member (28) movable in response to the energization circuit between a first position preventing key access through a keyhole during normal operating conditions and a second position permitting access through the keyhole during abnormal operating conditions. Accordingly, a key can only be inserted through the keyhole to actuate an unlocking bit of the auxiliary release mechanism to release the landing doors during abnormal operating conditions.

Abstract: A method for producing retinal nerve cells by inducing differentiation of iris pigmented epithelial cells into the retinal nerve cells. In a first method, iris pigmented epithelial cells derived from a mammal and embryo retinal stem cells derived from a bird are co-cultured. In a second method, iris pigmented epithelial cells of a bird or a mammal is isolated, and the iris pigmented epithelial cells is subjected to adherent culturing.  According to these methods, the retinal nerve cells can be produced by using iris pigmented epithelial cells collected from a patient per se. Therefore, there is a possibility that highly effective regenerative medical treatment can be realized.

Title: Self-tuning ultrasonic meter
Inventor: FREUND WILLIAM R
IPC: G01D3/08
Filed: 2004-09-08
Granted: 2011-04-19
Abstract: A method and related ultrasonic meter identify and correct for transit time errors such as peak switch errors. The method includes calculating values for a set of diagnostics from measurements of the fluid flow, including transit time measurements. Based on the values for the diagnostics, and whether and how they fall outside of their respective ranges, the meter can identify a variety of problems with the meter or fluid flow, such as whether there has been an intermittent peak switch, a permanent peak switch, or the presence of noise, velocity pulsation in the fluid flow, temperature stratification, or other problem. In the event there is a problem with the meter, the meter self-tunes in order to minimize the chances of the problem happening again.

Title: Process for the variable limitation of a flat flow channel and process for extracting a mass channel of variable geometry
Inventor: GROSS HEINZ
IPC: B29C48/92
Filed: 1996-09-25
Granted: 2009-05-12
Abstract: The geometry of a flow channel (1) can be varied within wide limits if at least one wall of the flow channel (1) takes the form of a sheet stack (2) which is pushed from the rear into the channel to a greater or lesser extent by means of adjusters (7). The adjustment may be effected either uniformly over the entire width of the flow channel (1) or only locally at certain points thereof. It is thus possible, while a medium is passing through the flow channel (1), to alter from outside the flow resistance either of the entire channel or only at certain points and thus alter the entire mass flow or the mass flow distribution as desired. New processing possibilities are given by the greater flexibility of the sheet stack (2) in relation to solid channel walls.

Title: Assembly structure and procedure for concrete towers used in wind turbines
Inventor: FERNANDEZ GOMEZ MIGUEL ANGEL
IPC: F03D11/04
Filed: 2006-11-10
Granted: 2014-09-30
Abstract: Structure and procedure for erecting concrete towers used in wind turbines in which said towers consist of sections (4) which in turn may each comprise a different number of segments (1) or longitudinal sections. The procedure includes two differentiated cycles, which may take place alongside each other: the pre-assembly of each section of tower and their assembly. The sections may be pre-mounted on bases (5) placed on the ground, with the segment in turn fitted with the help of struts (2) and mechanical jacks (3). This procedure is extremely versatile in that it makes the best logistic use of the material, resources and requisite assembly times since the assembly procedures for each section can be developed alongside each other in the different wind farm towers, and also greater heights can be achieved than is traditionally possible.
