Title: A one piece plastics closure having parallel wad support ribs, and moulding     apparatus
Inventor: VAUGHAN GEOFFREY
IPC: B65D41/04
Filed: 1992-03-05
Abstract: A one piece plastics closure 10 comprises top portion 24 having on its internal face a plurality of upstanding, substantially parallel wad, eg seal, support ribs 28 which extend from an internal peripheral wall 26 of radially recessed parts 20 and 22 of the top portion 24 inwardly beyond a skirt portion 12. The closure top 24 projects outwards and has a depending skirt portion 12. The internal face of the closure top portion 24 also has diametrically opposed parts 20 and 22 which are recessed radially outwardly relative to the internal wall 14 of the skirt 12. Preferably the closure is a one piece moulding having either screw threads for engaging the container or formations for a snap-on fit. The wad may preferably be laminated with a seal on one side and a low friction film on the other. Moulding apparatus comprises a central piece (43, fig 8) having two flanking pieces (50, 52, fig 6) arranged so that inner surfaces (70, 72, fig 6) cooperate with surfaces (74, 76, fig 8). This cooperation allow the central piece to be withdrawn, collapsing the mould so that the closure 10 may be removed. Moulding pieces (42, fig 8 and 50, 52, fig 6) are assembled into a mould cavity and liquid plastics, eg Homo Polymer Polypropylene, is introduced through feed lines and outlet nozzles (68, fig 6). During packaging a container is filled and flushed with nitrogen or oxygen. Adhesive is then applied to the containers rim and the closure with the wad in place is applied to the container pressing the wad onto the rim. On removal a foil or glassine layer is sheared from a pulpboard layer which remains on the rim. <IMAGE>

Title: Vectorable nozzle mounting for VSTOL aircraft
Inventor: BALSDON JULIAN GLYN
IPC: F01D25/12
Filed: 1992-05-16
Abstract: A swivelable nozzle 4 is mounted by means of a bearing on an intermediate fixed member 13, 15 such as a mounting ring on the airframe.

Title: A tensioned safety seat belt extension with anti- rucking mechanism
Inventor: COUPLAND PAUL EDWARD
IPC: B60R22/28
Filed: 1994-01-06
Abstract: A belt guide is connected to a support bolt by a pair of elastic members (a) each wound around the bolt and having free ends which pass through apertures in the belt guide and are knotted. The first elastic member is wound three times around the bolt, whereas the second elastic member is only wound twice therearound. This assembly is housed in a two-part cover as shown to contain the movements of the assembly. The cover is pivotally mounted on the bolt. Heavy loading on the belt extends the elastic members and draws the belt guide away from the support bolt. Hook formations at the sides of the belt guide may then engage the lower edge of the cover which is malleable and changes shape under load. In an alternative assembly only one elastic member is present. <IMAGE>

Title: Collapsible bicycle - uses tracks instead of wheels to save space
Inventor: LOGAN NINIAN SIMPSON REID
IPC: B62K15/00

Title: Power amplifier having nested amplitude modulation controller and phase modulation controller
Inventor: BLACK GREGORY R
IPC: H03C5/00
Filed: 1994-12-22
Abstract: Transmitting signals containing amplitude modulated (AM) and phase modulation (PM) components requires a transmitter having AM and PM control loops (515, 517). The PM control loop provides phase modulation, frequency translation and phase predistortion for a transmitter. The phase predistortion/correction is accomplished by using an oscillator (505), thus, the amount of PA phase correction is essentially unlimited. Additionally, the PM control loop (517) is nested about a power amplifier (507) (PA), allowing the PM control loop (517) to correct for any distortion introduced by the PA (507). <IMAGE>

Patent GB-2308935-A (GB)
Title: Thermal imager reference system
Inventor: SMITH BRIAN FREDERICK
IPC: G01J5/48
Filed: 1996-01-06
Abstract: A thermal imager referencing system comprises two rotating cranks in the form of discs (7, 8) each pivotally attached to connecting member (9). The discs (7, 8) are rotated at a constant speed causing two mirrors (not shown) laterally displaced along connecting member (9) to intercept an optical path X of a thermal imager associated with the referencing system. Each rotation through 360 degrees of the discs (7, 8) causes each mirror to pass once through the optical path, the mirror surfaces being respectively arranged to cause a linear array of detector elements (not shown) of the thermal imager to view alternately thermo-electric devices (14, 15), which are at different temperatures, during the flyback time associated with the thermal imager. The referencing system enables processing means of the thermal imager to normalise the detector array, compensating for DC offset and differences in gain between different elements of the detector array. The referencing system is of a particularly compact design and minimises the effect of any temperature variations across the surfaces of the Peltier on the normalisation process. <IMAGE>
