Title: Container with outlet duct
Inventor: JUANG MING JEN
IPC: B65D25/40
Filed: 1988-12-12
Abstract: A fluid container (1) has first and second openings (2, 5) and a duct (6) capable of being placed (a) in a first position in which it interconnects the first and second openings (2, 5) such that they are in fluid communication with each other, and (b) in a second position in which it is removed from one of the openings (2, 5) but not from the remainder of the container, the arrangement being such that, when the duct (6) is in the second position, both openings are in fluid communication with the surroundings of the container (1) and liquid may be poured into and out of the container through one opening, the other opening acting as an air hole. The duct includes a flexible portion (7) for ease of pouring. Each opening has a screw threaded cap associated therewith, one cap (8) has a central aperture through which the duct can pass, a rib (11) on the duct preventing separation of the cap from the duct on removal of the cap from the container. The other cap (12) is internally threaded, a lip (15) on a projection (4) of the container preventing separation of cap (12) from the container. Preferably the opening (5) is arranged in a hollow handle (3). <IMAGE>

Title: Moulding a textured or three dimensional surface onto a concrete block
Inventor: MARTIN CHRISTOPHER
IPC: B28B7/38
Filed: 1989-06-02
Abstract: The mould has one or more block moulding cavities, at least some of which incorporate a movable element (3) having a textured surface, forming one face of the mould cavity. The element is linearly or pivotally movable by a means (5) between a first advanced position in which the textured surface engages material to be moulded by compaction or compression in the cavity, and a second retracted position in which the texture element surface is disengaged from the moulded material, enabling block removal without damage of the textured surface. A cover (9) may be provided to prevent ingress of moulding material to the space (10) in which the element moves. Other mould cavity surfaces (13, 15) may be textured. The mould part defining the cavity walls may be raised to effect release from the moulded blocks, and simultaneously effect cleaning of the textured element surface, by a brush (21) carried by a moulding plunger. <IMAGE>

Title: Waveguide feeding array antenna
Inventor: KOIKE HIROSHI
IPC: H01Q21/06
Filed: 1990-11-06
Abstract: A waveguide feeding array antenna is provided to be capable of separating and taking up each of the polarization components of the horizontal and vertical polarized waves received concurrently at an opening of each of a plurality of waveguides arranged to form a network, by means of a taking-up equipment disposed in the waveguide circuit. Both polarization components can be made thereby to be effectively separated from and composed with each other while realizing the simplification and economization of the waveguide network. The polarized waves can be reported by a polarization filter (18, Figs 4 and 5) having horizontal slits (19). Waveguide arrangements are described having L shaped bends (Figs 6-9) or T shaped branches (Figs 10-12) which allow both polarized waves to pass. Further L shaped branches (Figs 22-25) T shaped branches (Figs 26-29) or H shaped al die cast base (Fig 33) wave guide arrangements are described. Alternatively the horizontal and vertical polarized waves may be converted to circular polarized waves (Figs 13 and 14). <IMAGE>

Title: Ensuring continuity in the supply of running strip
Inventor: BOLDRINI FULVIO
IPC: B65H19/18
Filed: 1991-03-27
Abstract: A method of changing a first running-out strip (3) for a new strip (33) on a manufacturing machine (2) uses a traction device (13) for feeding the first strip (3) to the machine (2) at a first predetermined speed, and a push device, eg. nip rollers (9, 49) Fig. 2, for feeding the new strip (33) along a U-shaped strip guide (12) at a second predetermined speed. The second speed is controlled as a function of the first speed, so that the loading portion of the new strip (33) overlaps a corresponding trailing portion of the first strip (3) along the strip guide (12). The push device is deactivated subsequent to engagement of the new strip (33) by the traction device (13). When roller (31) senses approaching roll depletion, the running-out strip (3) is cut at (11) and nip rollers (9, 49) activated when the cut trailing end is sensed at (55). A further sensor activates a suction device which causes the overlapped trailing portion to be diverted into a disposal device (57). <IMAGE>

Patent GB-913825-A (GB)
IPC: H01K1/14
Abstract: 913,825. Incandescent elements for electric lamps. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 10, 1961 [Oct. 13, 1960], No. 36341/61. Class 39 (2). An electric incandescent lamp has an incandescent element of refractory material having two spaced parallel limbs joined together at one end, the free ends being connected to current supply contacts, the length of the limbs being not less than four times the spacing between the limbs at their free ends. The refractory material may be a carbide, such as tantalum carbide, or a refractory metal. The limbs may be narrowed to about half width directly above the contacts to reduce shear stresses, and may also be thickened to compensate for the decrease in cross-section. Fig. 5 shows a limb 1 having cutaway portions 3 forming a narrow neck adjacent the contacts and thickened at the free end 6. Alternatively, when refractory metal strip is used, the edges of the ends of the limbs adjacent the contacts may be bent outwardly. In a further modification a series of parallel cuts may be made in the strip at the free end. Alternatively, the cuts may be made adjacent the free end and the metal 11, Fig. 12, twisted through a right angle.

Title: Casing with lid screw venting device
Inventor: ALLART BERNARD R
IPC: F16J13/02
Filed: 1992-01-09
Abstract: A casing comprises a casing body (1), a lid (3) fastened to the casing body by means of screws (9) which pass through the lid with clearance via screw passages (7), and an O-ring (6) interposed between said body and lid. Some screw passages (7) open out within the perimeter defined by the O-ring and into cavities (8) which are made in the lid and which permanently communicate with the interior of the casing.

Title: A liquid delivery system
Inventor: GODFREY PETER
IPC: B67D7/04
Filed: 1992-07-02
Abstract: The liquid delivery system is intended particularly for delivering fuel. A fuel tank 10 is connected to a dispenser 21 by an underground pipeline 17. The dispenser includes a valve 18 and a pump 20 by which fuel is pumped from the tank 10 to a nozzle 23. The valve holds the pump in a primed condition and prevents return flow of fuel to the reservoir along the pipeline 17. If the pipeline 17 develops a leak, fuel will then flow from the pipeline back to the tank 10, the fuel drawing air into the pipeline 17 from the point of the leak. If desired air can be admitted into the valve 18 through an openable bore 37 to allow fuel to flow from the pipeline 17 back to the tank 10. <IMAGE>

Patent GB-2366604-A (GB)
Title: Interface
Inventor: JOHNSON FREDERICK ALISTAIR
IPC: F15D1/12
Filed: 1992-09-08
Abstract: A marine vessel (1, Fig 1) has, on its surface immersed in a fluid medium, a number of piezo-electric elements 5, 10 thereon. Each element has, associated with it, an integrated circuit 8 which is programmed so as to cause the elements to modify the surface behaviour of the vessel enabling the surface to act as an extension of the fluid medium. This facility enables turbulence to be reduced, acoustic reflections to be cancelled, escape of noise from the vessel to be eliminated, and acoustic signals to be transmitted as and when necessary. Selected elements act as sensors and others as drivers. The elements may be used as submarines or aircraft.
