摘要:
@ A method is described for producing and projecting a theater quality entertainment motion picture, by photographing and then projecting the motion picture on a screen, which creates an unusually vivid impression of realism. The film frames have a resolution of over 40 line pairs per millimeter, and each frame has an area of at least 230 square millimeters (0.36 square inch), which creates more than 10 million pixels per frame on the film and on the screen. The illumination level on the screen is greater than 16.5 foot lamberts. The film frames are photographed and projected at a predetermined constant rate of more than 50 frames per second, such as 60 fps. The high resolution and ligh level, combined with the unusually high frame rate, has been found to produce an unusually vivid impression of realism.

A mobile accommodation unit, such as a caravan (1) has at least one extension part (2) movable between a retracted non-operative position substantially within or overlying the caravan and an extended operative position relative to the caravan. The extension part (2) has rigid walls, which are preferably made of sheets of a suitable synthetic polymeric material or metal sheeting having an interlayer of a suitable synthetic polymeric resin e.g. a polyurethane, to provide overall heat insulation and security. The extension part has a collapsible floor (5) comprising a plurality of strips, each connected to an adjacent strip along an intermediate line of articulation. The floor (5) is substantially planar in the extended operative position and folded-up or disarticulated in the retracted non-operative position within or overlying the caravan.

Piercable closure (12) for sterile or sterilisable medical/ pathology sample bottles, the closure being in the form of a dished cap apertured (28) through its end or base, and the cap aperture being closed by an added impervious membrane (36) that is more readily pierced than any practical integral thinning of the cap material. The membrane (36) is conveniently carried by an annular washer-like base member (32) whose aperture (34) registers with the cap aperture but is covered by the membrane.
摘要:
Railway traffic signalling light comprising a plurality of light emitting diodes 212 (LEDs) more than sufficient to produce total light emission adequate for intended usage, at least enough of said LEDs being energisable together to be so sufficient, the plurality of LEDs being deployed in an areal array in association with similarly areally distributed emitted light concentrating means 215 effective in conjunction with overall light output delivery provision to produce output light of predominantly substantially parallel directionality. Means for sensing and indicating failure of LED's may be included. Means for modulating light output in accordance with received information and a receiving means for such information may be included.

Controlled atmosphere entry/exit lock unit (10) for association with a controlled atmosphere cabinet (80), the lock unit (10) having two controlled access means (13; 30) both usually operable alternatively for sealing and communicating, one (30) relative to said cabinet (80) and the other (13) relative to outside, the lock unit further having atmosphere control means (70-78) operable for achieving internal atmosphere conditions compatible with what may be prescribed for said cabinet (80), the one access means having movable door means (30) and related powered actuation means (50; 30A, B) including for sealing relative to access with said cabinet (80).
摘要:
Device (10, 70) and method of fabricating as lamination of one thermoplastics layer (42) heated to bond or merge with another thermoplastics layer (43) and melt flow in permeating another layer (21) if present by agency of radiation passing through said other thermoplastics layer (43) without melting same. Tubes can be erected and laminated on site to line existing pipes or conduits (40). Stiff or flexible sheets or webs (70) can serve as special composite tiles or panels, or as conveyor belts.

Materials delivery devices, e.g. for drugs etc. (Figs 1-7) or body fluids (Figs 8-12), have administration means of piston-and-cylinder (100; 300) or peristaltic rollers and tube (546, 565; 646, 665; 746, 765; 846, 865; 946, 965) type, and intermittently incremental drive transmission means of cooperating toothed rack (143) or wheel (345; 445; 545; 645; 745; 845; 945) and deflectable biassed pawl (153, 156; 343, 356; 453, 456; 553, 556; 653, 656; 753, 756; 853, 856; 953, 956) type driven by pulsed reciprocating solenoid action (110; 310; 410; 510). Portable patient-wearable drug delivery devices (10; 30; 40; 50) can use pre-loaded cartridges (120; 320; 420; 520) and have solenoid drive (130) for needle-entry and battery-powered electronic control, etc. Intravenous infusion pumps (60; 70; 80; 90) can operate relative to body fluid reservoirs or for body fluid transfers.
摘要:
Method and apparatus for forming and packaging pad-like articles (10) of resilient compressible foam having one dimension (thickness) smaller than its other two dimensions. The pad-like articles are successively fed into an entry to a compression mechanism (20) having an interior space (21) in which each article is turned on itself to compress it in the one dimension (thickness-upon-thickness) by movement of bounding surfaces (22) of the interior space. The compressed pad-like articles (10c) are then pushed from the compression mechanism transversely to said movement of bounding surfaces of the interior space and a containing wrapping applied.
摘要:
A method and apparatus to automatically produce blocks of solid CO2 at low pressure. The apparatus includes at least one closed mold coupled to a liquid CO2 conditioner and a CO2 gas recovery system, and a control panel for automatic operation. The method consists in supplying liquid CO2 to this mold at a low pressure in order to fill the mold with CO2 snow of low density during a definite period of time, to then raise the pressure inside the mold to an intermediate pressure by supplying liquid CO2 at this pressure (and at a temperature of approximately -40 DEG C.) to form a dense mass of solid CO2 which after a definite time will block the admission of CO2 to the mold, causing a significant pressure drop that is used to create a signal to automatically close off the supply of liquid CO2 and finalize the production cycle of the block.
