Abstract: In order to determine the external profile of a diamond, particularly a large diamond which has re-entrant features, an elongate and thin beam is projected onto the diamond whilst the diamond is rotated about an axis normal to the beam; an imaging system is used to image from one side the line along which the beam strikes the diamond, this image being formed on a diffraction grating which is tilted in accordance with the Scheimpflug condition and in order to employ the first order beam of the diffraction grating. The image on the diffraction grating is viewed with a second imaging system. Furthermore, there may be a substantial improvement in light capture. The arrangement is applicable to systems other than those for determining profile.

Abstract: DISTRIBUTED FEEDBACK LASER FOR FREQUENCY MODULATED COMMUNICATION SYSTEMS Abstract To overcome the deleterious effects of the nonuniform frequency modulation response in semiconductor lasers due to current injection in direct frequency modulation applications, it has been determined that the linewidth enhancement factor a be made as large as possible. In one embodiment, distributed feedback lasers well suited for frequency modulation lightwave communication systems are designed to have an integrated feedback element such as a  corrugation grating whose effective pitch is selected to cause the Bragg wavelength and, therefore, the laser operating wavelength to be longer than the wavelength at substantially the maximum gain or gain peak in the semiconductor structure without the grating. That is, the wavelength of the grating is effectively detuned toward the longer wavelength and lower energy side of the peak of the gain profile. Such detuning increases the linewidth enhancement factor in such a way that the nonuniform frequency modulation response and its effects are minimized and, in some cases, substantially eliminated.

Title: Heat-sensitive recording paper
Inventor: OKUDA KATSUMI
IPC: B41M5/42
Filed: 1990-01-30
Granted: 1996-09-03
Abstract: A  heat-sensitive  recording  paper  comprising  a  sheet substrate, a heat-sensitive developing layer formed on the top surface of the sheet substrate that develops when heated, and a covering layer formed on the heat-sensitive developing layer which includes a pigment prepared by coating the surface of natural mica with at least one of titanium oxide and iron oxide.  The area of the heat-sensitive developing layer that develops appears in a colour different from that of the undeveloped heat-sensitive developing layer due to the regular multiple reflection of light which  takes  place  in  the  covering  layer.    Moreover,  the undeveloped part of the heat-sensitive developing layer has a pearl lustre which is also due to the regular multiple reflection of light in the covering layer.

Title: Pivoting tray for coin sorter
Inventor: RASMUSSEN JAMES M
IPC: G07D3/00
Filed: 1990-02-07
Granted: 1994-10-18
Abstract: ABSTRACT OF THE DISCLOSURE    In the field of coin handling, and particularly coin sorting, it is important to keep different batches of coins separated from one another.  A problem arises during the transfer of a batch of coins from a coin tray through an opening and into the coin sorting mechanism, because different batches of coins can inadvertently be mixed if the opening is not adequately protected.  To solve this problem, a coin tray is provided that includes a coin holding portion which is adapted to be pivotally mounted on the coin sorter.  The coin tray pivots between a coin holding position and a coin transferring position, and has an opening therein which allows coins to pass through the coin holding portion to the coin sorting mechanism.  A barrier portion prevents coins on the coin holding portion from entering the opening when the coin holding portion is in the coin holding position.  The barrier portion borders the opening, and is preferably stationary with respect to the coin handling machine.          When the coin holding portion is lifted into the coin transferring position, the barrier portion allows coins on the coin holding portion to enter the opening because the coin holding portion is higher than the barrier portion.  The interior of the barrier portion forms a chute which guides coins through the opening and into the coin handling mechanism.

Abstract: The specification discloses a process for producing a ferroalloy in a smelti ng vessel. A material containing an alloying metal is injected into a molten bath contained in the vessel.  A flux, a carbonaceous material and an oxygen-containing gas are also injected into the vessel. A gas which may be the oxygen-containing gas is injected into the molten bath in order to stir it. The rates of injection of the various components are controlled to achieve control of the oxidising and reducing environment within the vessel consistent with a rapide rate of injection. The material containing the alloying metal is either reduced and incorporated into the metal phase or oxidised and incorporated into the slag. Combustion gases  above the molten bath are oxidised to provide further heat to the process. Alloyed metal or stag containing the alloying metal are  recovered as product. The process is applicable to the production of ferroalloys such as ferrochromium, ferromanganese, ferronickel and ferrovanadium.

Abstract: A porous and spherical silica is recovered in high yields from a neutralized product of an alkali silicate obtained by using an acrylamide type polymer as a coagulation growing agent, and the above silica is reacted as a precursor with a metal compound of the Group II of periodic table in an aqueous medium to obtain amorphous or fine, laminar and crystalline porous and spherical silica or silicate granules having a high degree of true sphericality, a symmetrical grain size distribution and a refractive index over a range of from 1.4 to 1.7. The porous and spherical granules have a primary grain diameter of 0.3 to 30 µm as observed through an electron microscope, have an apparent specific gravity of from 0.05 to 0.5 g/ml, and are cheaply obtained in high yields, and can hence be used as a filler for various paints and resins.  In particularly, the granules excellently disperse in the resins, have a refractive index close to those of the resins, are not crushed during the kneading with resins or extrusion, or do not damage the apparatus.  The films obtained by using these granules exhibit very excellent transparency, anti-blocking property and scar resistance.  Moreover, the porous and spherical zinc phillosilicate type granules having fine grain sizes and symmetrical grain size distributions, are excellent in their odor scavenging property and sweat controlling property.

Abstract: Fluxing compositions containing compounds that generate acids upon photoinitiation from a light source such as Hg/Xe ultraviolet (UV) light sources are described. The acids clean oxides from the printed circuit boards (PCBs) under assembly and then volatilize with little or no need for a cleaning step, or cleaning only with water. The compounds that release an oxide removing agent, sometimes called a "photoacid" include metal and organic onium salts and furyl compounds bearing a carbonyl group. Such fluxing compositions can be used mixed with typical solder formulations. such as lead/tin solders, or applied topically thereto; both techniques permit the assembly of PCBs more easily and with high quality bonds.
