Title: Corner piece for a curtain pole
Inventor: GUALTIERI ORAZIO
IPC: A47H1/02
Filed: 1998-10-19
Abstract: A curtain pole corner piece of variable angle has two end sections 11 between which are located a number of wedge-shaped pole sections 7,9 having flat ends which are not parallel to each other. These sections have an axial aperture (21, Fig 4) through which a tension spring 13 passes. One face of each section 7 has a boss (23) surrounding the aperture and the other face has a corresponding recess (25) whereby abutting sections mate rotatably with each other. By twisting a section 7 relative to its neighbours the degree of curvature in the corner piece is adjusted. Sections 11 are attached to the ends of the main curtain pole and have threaded bores receiving the ends of the spring; rotation of a section 11 thus allows the spring to be tensioned. Seven pieces 7,9 may be used with the faces angled at 15{ to allow a maximum angle of 90{.

Title: Baffle mechanism for an I. S. machine
Inventor: LOVELL WALTER E
IPC: C03B9/36
Filed: 1998-11-04
Abstract: An I.S. machine has a blankmold (218) which is open at the top and includes inner (272) and outer (254) annular top sealing surfaces. Associated with the blankmold (218) is a baffle including a body (248) having a cup shaped portion (250) closed at the top, with a vertical cylindrical bore (266) open at the bottom, and an annular bottom sealing surface (252) for sealingly engaging the blankmold outer annular top sealing surface (254). A tubular sleeve (256) opens into, and extends vertically upwardly from, the top of the body. A piston (262) has a cylindrical head (264) including a top surface, a cylindrical sealing surface, and an annular bottom sealing surface (281) having a plurality of radial notches (286) across the bottom thereof. A tubular rod (260) extends vertically upwardly from the top surface for slidable displacement in the tubular sleeve (256), and a collar (270) is secured to the top of the rod. A spring (268) located between the collar and the cup shaped portion urges the cylindrical head (264) vertically upwardly to a position where the cylindrical head top surface engages the top of the cup shaped portion. The cylindrical head (264) may be displaced to a first location where a selected distance separates the top of the cylindrical head from the closed top of the cup shaped portion and another predetermined distance separates the cylindrical head annular bottom sealing surface (281) from the blankmold inner annular sealing surface (272). Further downward displacement of the collar (270) displaces the cylindrical head (264) relative to the cup shaped portion to a second location where the cylindrical head annular bottom sealing surface (281) engages the blankmold inner annular sealing surface (272). With this arrangement, when the piston is located at the first location, settle air can be directed through the rod (260), via passage means (278,280) into the cylindrical head (264), and hence through the annular separation between the cylindrical head annular bottom sealing surface (281) and the blankmold inner annular sealing surface (272) into the blankmold. When the piston is located at the second position, air from the blankmold can flow out through the notches (286) and passage means (278,280) into the rod (260).

Patent GB-2338096-A (GB)
Title: Arithmetic division method
Inventor: FENNY SIMON JAMES
IPC: G06T15/04
Filed: 1996-01-31
Abstract: An arithmetic division for implementation using hardware or software is performed by firstly storing the reciprocal of each nth value in a range 0 to X where n is greater than 1 and storing the differences between the reciprocals of the intervening n-1 values. A mantissa and an operand for an arithmetic division are received. One of the stored reciprocals is retrieved in response to the most significant part of the received mantissa and a set of differences is retrieved in response to a least significant part of the received mantissa. The differences and the reciprocal are summed and the result is multiplied by the received operand, thereby giving the result of the arithmetic division.
Patent GB-2341241-A (GB)
Title: Operation of an internal combustion engine during the start-up and after-start phase
Inventor: MENCHER BERNHARD
IPC: F02D41/04
Filed: 1999-08-16
Abstract: A fuel metering system increases the quantity of fuel supplied to an internal combustion engine during the start-up phase and after-start phase of the engine, in order to compensate for the increase in the condensation of the fuel on the manifold wall which occurs when the engine is cold. The system further has means for determining the pressure in the intake pipe of the engine, and for determining therefrom the gradient of the pressure in the manifold. The increased fuel quantity is then reduced by a certain amount in dependence on this pressure gradient. The increased quantity of fuel is also controlled in dependence on detected engine temperature. Thus the system takes into account the reduction in the film of fuel condensed on the manifold wall which can occur after engine start-up when the engine is not entirely cold and pressure gradients are large. The manifold pressure can be measured directly, or can be derived from a signal indicating the intake-air quantity or the contents of the cylinder.

Patent HU-T68049-A (HU)
Title: External fixator
Inventor: FAGGIOLI GIOVANNI
IPC: A61B17/64
Filed: 1993-07-11
Abstract: A dynamic external axial splint for use in rehabilitating a fractured bone comprises a pair of spaced clamps for bone screws or bolts anchored to the respective fragments of the fractured bone. A central body releasably and universally connects and locks these spaced clamps via ball-joints having provision for selective retention of a wide variety of angular relations, between the central body and the central axis of each of the spaced clamps. The central body comprises first and second end members and a third or intermediate member, affording on the one hand, longitudinally and adjustably fixed lap of one end member with the intermediate member, and also affording limited resiliently snubbed and axially guided displaceability as between the intermediate member and the other end member, thus rendering the two end members and the respective bone-fragment anchorages clamped to the end members subject to the same axially guided and resiliently snubbed action. The axially displaceable and resilient snubbed action is selectively neutralized by a single clamp adjustment which converts the dynamic external splint into a fixed external splint or fixator.

Title: Liposome-encapsulated phosphorylated nucleosides for treatment of retroviral diseases
IPC: A61K9/50
Filed: 1988-04-07
Abstract: The present invention provides a method for preventing or treating disease caused by retroviruses, particularly human immunodeficiency virus. Liposomes are prepared containing phosphorylated derivatives of nucleosides which act as chain-terminators of viral DNA. The phosphorylated nucleosides per se, without encapsulation in liposomes, do not readily enter cells. However, they are found to be effective if encapsulated in liposomes because they remain in liposomes longer, they do not escape easily from cells, and they constitute the active form for incorporation in viral DNA chains. When administered to a host, the liposomes are taken up by endocytic and phagocytic cells, which are important reservoirs of HIV infection. If coated with an appropriate ligand, such as an immunoglobulin molecule, liposomes containing the phosphorylated nucleosides can be directed to phagocytic cells, CD4-positive cells, or infected host cells.

Filed: 1989-02-24
Abstract: The present disclosure describes flame-retardant, high-temperature resistant polyimide fibers, nonwovens made from said fibers, as well as the fibers and molded articles obtained after a heat treatment. A composite of such fibers is heated to a temperature in the glass transition range of the fiber, i.e. between 280 DEG  and 350 DEG  C. This heat treatment develops a contraction force of 0.3 to 1.1 cN in the fibers which results in a fiber shrinkage of between 20 and 60% and the formation of cohesive bonds. The fibers of the invention enable the manufacture of molded articles that are particularly strong, have a high temperature resistance and flame-retardant properties, while having a relatively low density.
