Title: Instrument for observing jewels' brilliance as diamond, and method of taking photographs with said instrument
Inventor: YAMASHITA KINSAKU
IPC: G02B27/00
Filed: 1990-02-16
Abstract: The present invention relates to an instrument for observing the brilliance of jewels, especially of diamonds, and a method of  photographing  them  with  this  instrument.   The  instrument of this invention is composed of a lower tubular portion compris-ing  a  non-transparent  material  and an upper  tubular portion comprising a semi-transparent material, and a magnifying observ-ation lens can be furnished on the upper end part of said upper tuhular portion in accordance with using purposes of the instru-ment.   The  semi-transparent  upper  tubular  portion  can  move slidably with respect to the lower tubular portion.  The diamond is positioned on a placing part within the lower tubular portion, and an observer studies it from the upper end part of the upper tubular portion.  According to this instrument, the semi-trans-parent  upper  tubular portion adjusts  appropriately  the  light directing to the diamond,  and as a result,  it is possible to observe  characteristic  patterns  corresponding  to  the  diamond brilliance.  Further, the photographing method of this invnetion is  to  take photographs of diamonds within the  lower tubular portion with a camera from the upper side of the upper tubular portion of the instrument,  and it serves to judge the diamond brilliance  more  clearly  than  the  conventional  photographs  of diamonds.

IPC: A47J31/10
Filed: 1990-11-06
Abstract: The coffee brewing machine can be used to prepare alternatively normal coffee or espresso coffee and comprises a boiler having a temperature control. The cold water is fed to the boiler by a water pump with adjustable feed rate. Two different brewing members are used for the preparation of the two kind of coffees, namely a sieve holder and a filter support which are connectable via a mounting and supporting flange to the boiler. A mode switch is assigned to the mounting and supporting flange which automatically changes the mode of operation of the coffee brewing machine upon exchanging the brewing member. Thereby, the feed rate of the water pump and the temperature of the hot water are adapted to optimize the conditions for preparing either normal coffee or espresso coffee.

Inventor: NIVENS JERRY W
IPC: F25B41/42
Filed: 1990-01-23
Abstract: Appareil à passage intégral fonctionnant à température constante pour assurer la recirculation et le refroidissement (2) d'un liquide frigorigène en interrompant le cycle normal du frigorigène pour permettre l'admission d'un liquide à plus basse température à l'intérieur du détendeur (5), ce qui permet d'alimenter le compresseur (9) d'un gaz à plus basse température et à plus basse pression, et qui contribue à diminuer les besoins et les coûts énergétiques associés au fonctionnement du compresseur. Cette réduction de la pression et de la température entraîne également une diminution des coûts d'exploitation et d'entretien, et se traduit par l'utilisation de moins grandes quantités de frigorigène. La construction d'un refroidisseur intermédiaire est un facteur-clé pour atteindre les objectifs mentionnés ci-dessus; celui-ci doit être construit de manière à ne pas entraver la libre circulation du liquide, tout en préservant le contact physique direct entre la conduite d'aspiration du compresseur (22) et la canalisation de frigorigène en cuivre (24), afin d'assurer un transfert thermique optimal et une réduction de la pression à l'intérieur de l'ensemble du système.

Title: Rerouting and change-back systems for asynchronous transfer mode network
Inventor: OMURO KATSUMI
IPC: H04L45/24
Filed: 1991-06-17
Abstract: A change-back system is designed for an asynchronous transfer mode network in which a rerouting path is set to replace an original path when a fault is generated in the original path within the network, which network includes a plurality of communication nodes which are coupled via lines and communicate information in the form of cells, and the original path and the rerouting path couple first and second communication nodes within the network.  The change-back system makes a change-back process to change the path used from the rerouting path to the original path when the fault is restored.  The change-back system includes a first circuit for detecting a restoration of a fault in the original path, a second circuit for transmitting a cell from the first communication node to the second communication node via each of the rerouting path and the original path when the restoration of the fault is detected, prior to making the change-back process, and for measuring a first time it takes for the cell to travel through the rerouting path and a second time it takes for the cell to travel through the original path, and a third circuit for calculating a guard time which is a difference between the first and second times and for delaying transmission of a cell from the second circuit to the original path after the restoration of the fault, so that the cell after the restoration of the fault is transmitted to the original path at least after a time which corresponds to the difference from a time when a cell is last transmitted to the rerouting path immediately before the fault is restored.

Title: Iodo compounds
Inventor: MCKILLOP ALEXANDER
IPC: C07C69/63
Filed: 1990-02-28
Abstract: ABSTRACT OF THE DISCLOSURE         Diacetoxyarene compounds are obtained by reacting a perborate such as sodium perborate monohydrate or tetrahydrate and acetic acid with an iodoarene compound under mild conditions, such as 40 to 50°C.  The iodoarene can be further substituted by a wide range of substituents, such as halo, nitro, alkyl, alkoxy or carboxylic acid, in any position around the nucleus, except that electron-withdrawing substituents occupy meta positions only.  The invention process thus enables a wide range of substituted diacetoxyarene compounds to be produced using widely available and easily handled materials under mild operating conditions.

Abstract: ABSTRACT     A method of accessing a base station from a mobile station in a mobile radio system, in which the mobile station communicates with the base station in one or more time slots included in a frame according to the TDMA-principle. In one time slot, there are reserved fields for control information (SACCH, DVCC) which, however, are not used in the uplink and the downlink communi-cation if the time slot represents a digital control channel.
