Abstract: A dish support is rotatably mounted on a base (2). An electrical heating element heats the support and dishes resting on its surface. The support is preferably mounted on rollers (10) which run in a track (13) on the base (2). Thermal storage means in the support store heat supplied by the element. The support can be picked up and removed from the base to connect the element and thereby heat the storage medium. It can then be discontinued and placed on the base so that the dishes can be kept warm by the stored heat.

Abstract: The wound dressing securement device has one or more flexible adhesive base member strips (12,14) that are secured to the skin around or at opposite sides of a wound (50) with sufficient clearance for a wound dressing (60). A plurality of sheet retention members (30) joined to one or more of the base members (12,14) project vertically from an exposed surface of the base member. A flexible, foldable, stretchable hold-down sheet (40) member has a plurality of openings to engage with engagement heads provided on the sheet retention members (30). The hold-down sheet member is sized to form a cover for the underlying wound dressing and bears against the wound dressing to hold it in position on the wound. When the wound dressing is to be changed, the hold-down sheet member is disengaged from the sheet retention members to uncover the wound dressing, and make it accessible for removal and replacement. The adhesive base member(s) remain in place during repeated changes of the wound dressing.

Abstract: The present invention relates to an electron tube cathode comprising a hollow cylindrical structure of thermo-emissive wires which is mounted between two conducting supports (5,6). The two supports (5,6) are firmly mechanically attached to one another. In order to avoid deformation of the cathode during ignition and extinguishing of heating, use is made of at least one spring (53) integrated with one of the supports and placed in proximity to the thermo-emissive wires. The spring is made of a material which has, at ambient temperature, elastic properties which are less good or equal to that which it has at a temperature greater than ambient temperature. Application: grid electron tubes. <IMAGE>

Title: Overhead projector with achromatic fresnel lens
Inventor: VANDERWERF DENNIS F
IPC: G02B3/08
Filed: 1994-05-26
Abstract: A low-profile, transmissive overhead projector (10) (OHP) employs a novel condensing lens system having a catadioptric Fresnel lens (28) and a dioptric Fresnel lens (30). Each of the lenses exhibits chromatic aberration, but the dispersion of one lens is selected to cancel out the dispersion of the other, e.g., if the catadioptric lens has negative dispersion then the dioptric lens is selected to have positive dispersion. The mutual cancellation of the dispersion of each lens practically eliminates longitudinal chromatic aberration through the lens system. The lens system provides a fast condensing system which allows collimation, dispersion or concentration of light striking the lens at a high angle of incidence. This characteristic is particularly suited for a low-profile OHP as it allows the light source to be placed directly under, but very close to, the stage area.

Abstract: A multiplex broadcasting station selecting method which can execute a station selecting operation in group units is provided. A PTY code to be compared and a channel are set to one set of large classification information. The user sequentially calls out the PTY codes to be designated to one group and depresses the same channel key or the like each time the desired PTY code is called, thereby storing into memory the large classification information in which a plurality of PTY codes are made correspond to a same channel number. When executing a retrieving operation, the user depresses one operation key. The large classification information corresponding to the channel number is consequently selected and the group having a similar genre can be retrieved as set. The user can receive either one of or all of the broadcasting stations in the large classification information of the group. A process such that the group is allocated to each of the channels which was conventionally impossible can be executed, so that the range of application of the RDS broadcasting is broadened.

Abstract: On a GaAs substrate (Al Y Ga 1-Y ) 0.5 In 0.5 P crystal layers (0≦Y≦1) is formed to be lattice-matched with the substrate. By radiating As molecular beams on the surface of the crystal layers while heating the layered substrate to a temperature at which In in the crystal layers evaporates, the portion near the surface of the crystal layers is changed into an Al Y Ga 1-Y As crystal layer (0≦Y≦1) of a thickness of several molecules, on which layer an Al X Ga 1-X As crystal layer (0≦X≦1) is formed. Since the surface of the Al Y Ga 1-Y As crystal layer has been purified, the formed Al X Ga 1-X As crystal layer has a high crystallinity, allowing production of a light emitting diode, a semiconductor laser device and the like with high efficiency.

Abstract: Combustion in a gas turbine is controlled through use of flame spectroscopy in order to achieve low NO x  emissions in the exhaust. By detecting and monitoring the combustion flame in the turbine to determine intensity of ultraviolet spectral lines, and dynamically adjusting the fuel/air ratio of the fuel mixture such that this intensity remains below a predetermined level associated with a desired low level of NO x  emissions, the engine produces significantly reduced NO x  emissions in its exhaust but at a sufficiently high combustion flame temperature to avoid any undue risk of flame-out, thereby assuring stable, safe and reliable operation.
