Abstract: A metered dose inhaler comprises a piston (3) which is mounted in a cavity 12) within a body (1), and is urged by a pre-loaded spring (6) into a reduced cross-section pressure chamber (4). The piston (3) may be loaded by means of an actuating rod (31) having a handle (32), and may be latched in a loaded position by a latching means (33). A liquid drug (e.g. in aqueous solution) is contained in a collapsible bag (10). Metered quantities of the drug are successively presented in the pressure chamber (4), and then subjected to a sudden and great increase in pressure, to eject the liquid drug through an atomising head (22), to reduce it to a fine atomised spray of small mean particle size - for example, less than 30 micrometres. Non-return valves (13 and 23) control the flow of liquid through the device. The sudden pressure pulse is caused by releasing the spring loaded piston (3), upon depressing an actuating button (35) connected to the latching means (33).

Abstract: SUCTION FITTING WITH PUMP CONTROL DEVICE                ABSTRACT OF THE DISCLOSURE          A suction fitting for use in a water circula-tion system, the fitting having a perforated body that is mounted to permit fluid flow through both front and rear perforated faces, and thereby minimize the possi-bility of complete blockage of the fitting by entrapped hair or skin. Operation of a circulating pump is con-trolled to prevent damage to equipment and property and also to minimize the possibility of serious personal injury or death. The suction fitting further includes a suction tube for connection to the pump, for circula-ting water in the tub or spa back through jets in the tub or spa, and a pressure sensor line connecting the water in the tub or spa to a water level sensor. The front face of the perforated body has a number of grooves,  to provide fluid communication between the pressure sensor line and the suction tube, through one or more front-face perforations.  When flow into the suction fitting is blocked,  a reduced pressure is sensed immediately behind the front face of the perfor-ated body,  through the pressure sensor line and the grooves in the front face, and the pump is disabled to prevent damage or physical injury.

Abstract: An apparatus and method for providing accurate layer registration for multiple layer electronic printing systems discloses a means and a method of reducing the positional scan-to-scan error in a multiple layer electronic printing systems, typically multi-bearm laser raster output scanners, in which accurate layer registration is critical. The method comprises determination of a time delay between page sync signal and start-of-scan signal, using this delay to determine delay dependent offset factor called the phase registration parameter, and correctively mapping image data to proper output channels based on the phase registration parameter and the laser number. The phase registration parameter must be determined at the beginning of each scan layer and the offset factors must be re-adjusted based on the new phase delay.

IPC: C03B37/027
Filed: 1993-06-18
Abstract: The presence of (typically unintended) birefringence in single mode optical fiber can severely limit the usefulness of the fiber for, e.g., high bit rate or analog optical fiber communication systems, due to the resulting polarization mode dispersion (PMD). It has now been discovered that PMD can be substantially reduced if, during drawing of the fiber (13), a torque is applied to the fiber such that a "spin" is impressed on the fiber. Desirably the torque is applied such that the spin impressed on the fiber does not have constant spatial frequency, e.g., has alternately clockwise and counterclockwise helicity. At least a portion of optical fiber according to the invention has a spin whose spatial frequency exceeds 4 spins/meter.

IPC: G09F9/37
Filed: 1991-12-16
Abstract: A display assembly comprises a plurality of elements mounted in an array to form spaced parallel rows. Each element in each row has at least two signal faces and is rotatable about a common axis of its respective row to expose a signal face at a presentation surface (8). At least one setting station (24) is disposed adjacent one side of the array and has a number of actuators (26) arranged in a line parallel to the rows. The array of elements is movable relative to the setting station or stations (24) in a direction perpendicular to the rows and each actuator (26) is adapted to selectively engage an element during such movement to determine which signal face thereof is exposed. In this way, a full traverse of the array by a setting station (24) creates a predeterminable image comprising exposed signal faces at the presentation surface.

Abstract: In a selectively called radio receiver in which a demodulated signal of a specific bit rate is produced with battery saving kept in synchronism with the demodulated signal, a bit rate detecting unit detects the bit rate with a controllable sensitivity while the synchronism is lost. A bit rats detecting control arrangement controls the sensitivity within a predetermined sensitivity range, The bit rate detecting unit may misdetect the bit rate with a variable misdetection rate which is accumulated to an incremented amount from an initial amount representative of no disdetection while the synchronism is lost. The bit rate detection control arrangement may decrmement the misdetection rate to the initial amount when the incremented amount reaches a predetermined amount, Alternitively, the bit rate detection control arrangement may control the misdetection rate between a greater and a smaller amount and then cause the misdetection rate return to the initical amount. In either event, the bit rate detection control arragement controls the sensitivity within a predetermined range,
