Title: Infrared radiation source incorporating a raman medium for isotope separation
Inventor: ANDREOU DOROS
IPC: H01S3/108
Filed: 1991-05-24
Abstract: A tuneable infrared radiation source has a laser cavity 10, 13, a Raman medium positioned within the cavity, and a subcavity 16, 13 through which a Raman shifted beam (Stokes or anti-Stokes) can be emitted. The cavity has minimum output coupling and minimum losses so that a laser pulse is fully developed before Raman threshold is achieved, and the output Raman beam is emitted through the subcavity. The Raman shifted wavelength can be tuned using grating 10. A germanium etalon separates the subcavity, which may contain para-hydrogen or deuterium, from the main cavity which may contain a CO2 laser. The laser cavity may accommodate a focal beam waist (56, Fig 5). The laser may operate between a mirror (60, Fig 6) and the surface of a lens (68, Fig 6) with the Raman subcavity operating between inner surfaces of lenses (64, 68, Fig 6). The source produces 16 mu m radiation for Uranium Hexafluoride isotope separation. A series of sources may be fired parallel to each other through supercooled UF6 gas (L1-L5, Fig 7), and a beamsplitter (76, Fig 7) may be used. <IMAGE>

Title: An apparatus for detecting the presence of a person inside a room having a door
Inventor: ICHIKAWA MASAHIRO
IPC: G08B13/19
Filed: 1991-09-02
Abstract: The apparatus comprises a pyroelectric infrared sensor 1 and a piezoelectric air pressure sensor 2. The infrared sensor detects movement of a person and produces a signal indicating the movement. The air pressure sensor detects opening and closing of the door and produces a signal indicating the opening and closing. A logic device including monostable multivibrators 4a, 4b, 4c, 4d. 4e, AND gates 5a-5e, and an OR gate 8 is connected between the outputs of the two sensors. When the signal indicating the movement is applied to the logic device later than the signal indicating the opening and closing. the logic device produces a signal indicating the entry of a person. When the signal indicating the opening and closing is applied to the logic device later than the signal indicating the movement, the logic device produces a signal indicting the exit of a person. These signals are processed by the logic device to know the presence or absence of a person. <IMAGE>

Title: Device for restricting the flow of a fluid
Inventor: ENGLISH CHRISTOPHER JOHN
IPC: F16L55/027
Filed: 1991-11-19
Abstract: A flow-control device comprises a coil (10) which is an interference fit in a slot defined by a carrier (11). The coil restricts flow of the fluid through the slot, from surface 12 to surface 13, flow taking place through the interstices between the outside of the coil and the boundary surfaces of the slot. Two fluids can be mixed by both having an inlet to the slot with there being a common outlet from the slot. The end wall abutting the coil may be moveable so that the size of the interstices can be adjusted. <IMAGE>

Title: "joining together elements of a furniture construction system"
Inventor: SCOTT GEORGE WILBERT SAMUEL
IPC: A47B17/00
Filed: 1992-01-09
Abstract: This invention relates to the construction of office and modern home furniture by an assembly process which involves the use of several different connecting and bridging elements which in practice will normally be made of light alloy metal. The basic load transmission elements of the furniture construction system are joined together directly by means of one capscrew and where rotation about this screw is prevented by the provision of dowels in dowel holes in the surfaces to be connected; or indirectly through short or long beams in a similar manner; or the elements may be each capscrew and dowel connected to a polygonal hub. After the selected elements have been assembled into the desired shape of furniture the resulting unit can then be clad or topped with functional items such as glass table tops, office desk slabs and suspended drawers and filing cabinets.

Title: A shock valve
Inventor: HARPER-BOURNE MARCUS
IPC: B60R21/268
Filed: 1992-08-13
Abstract: A shock valve for releasing a fluid in response to an acceleration applied to the valve above a threshold value includes a fixed lever arm (1) defining a sealed fluid passageway (4) therein and an associated mass (2). During acceleration the mass (2) exerts a bending moment on the arm (1) causing the arm to fracture at a weakening incorporated therein. The weakening may comprise a peripheral groove (5) formed around the arm (1). The mass may be separate from the arm as shown and include an anti-rattle device in the form of a coil spring (24) or a plate spring (figure 5, not shown). Alternatively the mass may be integral with the lever arm. The valve has been found to perform reliably and predictably and is particularly useful for controlling the release of cooling fluids in missiles eg for the seeker head of a mortar shell.

Title: Dyeing tissues
Inventor: MIZUSAWA YOSHITADA
IPC: G01N1/31
Filed: 1992-09-14
Abstract: Apparatus for dyeing tissues has a dyeing tray (3) with a plurality of plateaux (12). A slide is placed over each plateau to form a wedge-shaped capillary gap between the plateau and the undersurface of the slide carrying a tissue sample. A liquid drip surface (13) and a liquid discharge port are formed at one end of the top surface of each plateau. A liquid delivery port (18) in a sidewall (28) of the tray communicates with the liquid discharge port. A dyeing liquid is dripped onto the exposed drip surface and spreads into the gap for dyeing the tissue. After dyeing used liquid is sucked and discharged by way of the liquid delivery port.

Title: End fittings for reinforced elastomeric tubes
Inventor: VANCE JAMES C
IPC: F16L33/01
Filed: 1992-10-29
Abstract: A coupling device is adapted for attachment to an elastomeric tubular body 28 having integral, looped reinforcement fibers 16 as part of a tubular assembly. The coupling device includes a coupling member 30, a stem 24 and a mechanism 8 for retaining the elastomeric tubular body 28 in sealing engagement with the stem 24, when connected therewith.

Title: Simulated projectile vision
Inventor: COURTNEY WILLIAM ALEXANDER
IPC: G06T15/10
Filed: 1993-10-12
Abstract: In order to improve television coverage of sports which involve the flight of a projectile over long distances, such as golf or archery, a simulated view of the projectile's landing zone, as seen from the projectile, is produced in real time. Microwave radars or sonars 3, 4, 5 measure the distance to projectile 2 at two instants. From these the trajectory 1 of projectile 2 may be calculated, ignoring wind, spin and air resistance, and hence the estimated landing zone may be determined. This is then combined with either a real-time image produced from a camera located external to the projectile, or with a map or pre-recorded image of the landscape, to provide the simulated view. Thus the viewer will be shown a dramatic view of the game. <IMAGE>

Title: Light emitting diodes with modified window layers
Inventor: HUANG KUO-HSIN
IPC: H01L33/00
Filed: 1993-12-08
Abstract: A light emitting diode includes a first conductivity type semiconductor substrate, a basic AlGaInP double heterostructure and two window layers of second conductivity type semiconductor. A layer of first conductivity type AlGaInP an undoped AlGaInP layer and a layer of second conductivity type AlGaInP form the double heterostructure. The AlGaInP layers are epitaxially grown above the substrate sequentially. The window layers contain one layer of GaAs and the other layer of GaP. The first window layer is formed by epitaxially growing GaAs over the AlGaInP heterostructure. The second window layer is formed by growing GaP directly on the first window layer using either OMVPE or vapor phase epitaxy (VPE) technology. The inclusion of a GaAs window layer increases current spreading and, hence, the efficiency of the device. The yield rate of manufacturing the light emitting diode is also increased because the quality of GaP layer surface is improved. <IMAGE>
