An inertial sensor unit for determining north, has a housing and a positioning gimbal rotatably mounted in this housing about a substantially vertical axis. A releasable, cooperating detent mechanism defines three fixed angular detent positions of the positioning gimbal about the substantially vertical axis relative to the housing. The positioning gimbal is successively rotated into the three detent positions. A fiber optical gyro is mounted on the positioning gimbal. The input axis forms an acute angle with a substantially horizontal axis orthogonal to the above mentioned substantially vertical axis. A signal processing system is provided, to which the signals generated by the fiber optical gyro in the three detent positions are applied. The signal processing system provides, therefrom, the angle between a reference direction and north.

A valve structure that includes a housing, a valve element, and a seal. The housing includes a first communication path between a first port at a first pressure level and a second port at a second pressure level. The valve element is movable with respect to the housing between a first position, a second position, and an intermediate position between the first and second positions. The first position permits substantially unrestricted fluid flow between the first and second ports. The second position substantially prevents fluid flow between the first and second ports. The seal is located at an interface between the housing and the valve element. The seal deforms in response to a differential between the first and second pressure levels such that at the intermediate position, there is restricted fluid flow between the first and second ports.

An assembly for the transfer of operating movement around the corner of a window or door, particularly tilt/turn closures, involves an angled casing, guiding a flexible deflection member, which connects the operating rods of the closure. An intermediary connecting member between the flexible deflection member and an operating rod forms a slide bolt, preferably a tilt-lock locking-slide, which is stiffened by a longitudinal batten. The batten fits in a slot on one leg of the angled casing. The sliding bolt engages the flexible member by means of a cam-and-recess. The batten stabilizes the flexible member when it is under compression. The assembly and the sliding bolt are shaped to allow insertion in grooves in the profiles which form the closure frame. A clamping piece holds one of the legs in the frame. Elements of the assembly assist in dispersing transverse forces which can cause binding.

The present invention relates to a method wherein communication links between subscriber access lines of subscriber access units of an exchange in a switching system comprising a number of exchanges are established within the exchange concerned either directly in the respective subscriber access unit or between the subscriber access units connected by trunk lines directly to one another or via at least one subscriber access unit, without involving a central switching device of the exchange concerned, and under the control of the central controller belonging to this exchange.

A vapor purge system that permits evaluation of the system with a minimum number of hoses and connections, and without the use of additional components. The system includes a valve having first and second ports in communication with a first chamber and a third port in communication with a second chamber, the first and second chambers being defined by a metering member that divides an internal volume of a housing. A first conduit connects a diagnostic member having first and second operative states with the first chamber, the connection being made through the second port. The first operative state prohibits communication with an exterior of the valve, and the second operative state permits communication with the exterior. The diagnostic member provides the ability to reliably measure flow through the valve. The system can use three (3) hoses including five (5) connections from a vapor supply port connected with the first port to the third port operatively connected with a manifold.

A window or a door with a panel (1) mounted on a fixed frame (2) on or near an upright boundary edge by hinge fittings (5, 6). To relieve the hinge fittings (5, 6) of the vertical component of the force of weight or load of the panel (3), a brace (11) is provided, engaging with the panel (3) on the one hand in the area of the hinge fittings (5, 6) and on the other hand, anchored to the fixed frame (2) against the force of weight or direction of load of the panel (3). The brace is provided above, but adjacent to, a lower corner hinge.

In a wing frame 1 for windows, doors, or the like, composed of metal or plastics profiles, the actuation gear assembly 10 for a connecting rod 9 is so housed that adjacent an undercut profiled guide channel 5 for the connecting rod 9, an installation space is required which corresponds to only a fraction of the maximal cross-sectional height 23 of the gear housing 13. For this purpose the bottom 8 of the guide channel 5 is provided with a perforation 27 through which can be passed the first housing section 15, which stores the pinion 14 of the actuation gear assembly 10.

A washing brush contains a brush body with a central opening, that engages a cylindrical projection, which is positioned in the vicinity of the edge of a cover. The cover is in one piece with a gripping member, which can be connected to a water-carrying member.In the center of the cover and the brush body is provided an annular locking member, which passes through the cover within the liquid-carrying area in the form of a push button. By depressing the push button, it is possible to release the angular locking member between the gripping member and the brush body.

A tape cassette, particularly a magnetic tape cassette, has two or more windows which are separated from one another by a separator housing member and which are located on a common carrier which may consist, for example, of connecting webs between the windows. The window arrangement is useful in standardized cassettes, for example compact cassettes, as well as in all other film, sound, video and data cassettes.
摘要:
A system and method for controlling evaporative emissions of a volatile fuel. The system preferably has a fuel vapor collection canister, a purge valve, an isolation valve, a fuel tank, and a vent valve. The fuel vapor collection canister includes a supply port and a discharge port. The purge valve includes an inlet port and an outlet port. The inlet port of the purge valve is in fluid communication with the discharge port of the fuel vapor collection canister. The isolation valve includes a housing, a valve body, and a seal. The housing has a first port in fluid communication with the supply port of the fuel vapor collection canister, a second port, and a fuel vapor flow path that extends between the first and second ports. The valve body is movable with respect to the housing along an axis between a first configuration and a second configuration. The first configuration permits substantially unrestricted fuel vapor flow between the first and second ports, and the second configuration substantially prevents fuel vapor flow between the first and second ports. The seal, which is located at an interface between the housing and the valve body, includes an annular lip that projects obliquely toward the axis in the first configuration. The fuel tank is in fluid communication with the second port of the isolation valve. Thus, the fuel tank can be isolated from the fuel vapor collection canister while purging the fuel vapor collection canister. The vent valve controls ambient fluid flow with respect to the fuel vapor collection canister
