Title: Vehicle safety belt test apparatus and method
Inventor: KIDD JAMES
IPC: G01M99/00
Filed: 1997-09-16
Abstract: A vehicle  safety belt  test  apparatus  (10)  and method is described.  The apparatus is comprised of a frame (11) which is adapted to be positioned on a seat (12) of a vehicle and disposed to distribute pressure substantially evenly on the seat.  One or more pistons (16) are secured to the frame and to a seat belt support curved member  (15). The support curved member (15) is adapted to receive opposed free ends of two spaced-apart seat belt portions (21,  21') of a seat belt thereover with a buckle (22') of the seat belt securing the opposed free ends together.  The seat belt portions (21, 21') are secured at a securing end (35) to a frame of  a vehicle.   A pressure control  device  (17)  is provided to actuate the pistons (16) to displace the seat belt support member (15) relative to the frame whereby to exert a predetermined force on the seat belt portions (21, 21') to test the restraining strength of the seat belt.

Title: A method of seaming a circular cover panel onto the body of a can
Inventor: JAKOBSEN HANS JORGEN GRAA
IPC: B21D51/34
Filed: 1996-03-29
Abstract: A method of seaming a circular cover panel (1) provided with a turnable pull ring (2) onto the body of a can. The cover panel comprises a circumferential score line (5) as close as possible to the rim portion (6) of said panel. The pull ring (2) on the cover panel used is mounted in a non-radial position on said cover panel (1) with the result that a clearance (<u>a</u>) is provided between the rim portion (6) of the cover panel and the nose (3) of the pull ring, and a clearance (<u>b</u>) is provided between the rim portion (6) of the cover panel and the handle part (2) of the pull ring. As a result, a closing chuck can be inserted in these clearances (<u>a</u>, <u>b</u>) during the seaming of the cover panel. In this manner the seaming operation is very simple and very rational because it is not necessary to use a particular closing chuck, and because the cover panel need not be angularly positioned on the seaming machine before the closing chuck and the cover panel are moved towards each other.

Title: Self-adjusting ball valve assembly
Inventor: KOSKINAS JOHN
IPC: F16K5/20
Filed: 1996-09-05
Abstract: A self-adjusting ball valve assembly having a ball valve body, a shaft assembly or shaft mounted to the ball valve body, a spherical segment carried by the shaft, and elements for adjusting the position of the shaft. The ball valve body (12) has a port (10a, 10b) for fluid transit therethrough and a first through passage, located concentrically about a body axis. The shaft (34) rotatably mounts through the first through passage along a shaft axis (16), which is maintained parallel but offset from the body axis (42). The spherical segment (14) mounts to the shaft and radially extends from the shaft axis within the ball valve body, and includes a portion (14b) for sealing engagement with the port, upon rotation of the shaft through a predefined angle. The adjustment elements automatically adjust the offset between the body axis and the shaft axis to enhance the sealing engagement between the spherical segment and the port. A drive unit coupled to the shaft carriage reactively translates the shaft as the ball segment rotates enhancing seating of the valve and reducing the load on wear surfaces during valve operation. The segment is keyed to the shaft with dowel pins (36) and the shaft itself may be locked against rotation with pins that are selectively moved into cross-apertures. A shear coupling prevents damage to the shaft or drive unit when the shaft is locked.

Title: Real time control architecture for admission control in communications network
Inventor: CLARK TIMOTHY IAN JAMES
IPC: H04L12/56
Filed: 1998-02-24
Abstract: The present invention relates to communications network and particularly although not exclusively to a method of optimizing the performance of a communications network with respect to admission and control of communications data. A communications network comprising N node elements operates N decision tables (1000) for controlling admission and control of data communications to the N node elements. Each node element generates corresponding performance data, and the N decision tables and N performance data are collected at a central network controller. The network controller determines a set of new decision tables (1004) from the collected decision tables (Fig. 10) and distributes a new set of decision tables (1006) to each of the N node elements, which then proceed to operate the new decision tables throughout the network (1000).

Title: Pen-type injector drive mechanism
Inventor: KOVELMAN PAUL H
IPC: A61M5/172
Filed: 1996-09-06
Abstract: A medication injection mechanism, for delivering a dosage of medication from a medication cartridge having a piston, includes a two-piece drive shaft, a ratchet mechanism, and a drive mechanism. The two-piece drive shaft includes a plunger portion and a drive portion. The plunger portion has an end that contacts the piston of the medication cartridge, ratchet teeth disposed on the sides of the plunger portion that define a thickness of the plunger portion, and an opening to provide a passage through the plunger portion of the two-piece drive shaft. The drive portion is formed by rails that are coupled together by a connector that passes through the opening in the plunger portion so that the drive portion is coupled to the plunger portion, and can move relative to the plunger portion. Each of the rails forming the drive portion has threads on a surface that extend beyond the defined thickness of the plunger portion. The ratchet mechanism engages with the ratchet teeth of the plunger portion to permit the movement of the plunger portion toward the piston of the medication cartridge and to inhibit movement of the plunger portion away from the piston of the medication cartridge. Also, the drive mechanism engages with the threads on the rails of the drive portion, but is free of contact with the ratchet teeth on the plunger portion to adjust the position of the drive portion relative to the plunger portion so that the drive portion can be moved toward the piston of the medication cartridge a fixed distance and the plunger portion is moved a distance that is less than or equal to the fixed distance.

Filed: 1996-12-13
Abstract: A desalination plant (10) is disclosed which includes a pump for pumping water at a pressure of between 50 and 65 Bar to a generally cylindrical filter element (30) which includes a plurality of reverse osmosis membranes defining salt passages. Immediately upstream of the filter element (30) there is a disc (40) with a plurality of holes (44) in it.  The disc (40) forms an obstruction which causes a pressure drop between the upstream side thereof and the downstream side. It also divides the water flow into a series of separate streams which impinge on the end of the filter element and flow into the salt passages. The water downstream of the obstruction is not only at a lower pressure than the water upstream of the obstruction but also is flowing turbulently.  The disc (40) and filter element (30) are in a cylindrical casing (12). The brine which emerges from the filter element, and which is still at a substantial pressure, can be fed through a device such as a Pelton wheel to recover some of the residual energy therefrom.
