Title: CCD image converter - has horizontal CCD region whose lower part corresponds to output gate with blocking ion layer
Inventor: JUNG HUN JUN
IPC: H04N5/335
Filed: 1991-10-14
Abstract: The HEED region has an output gate to form potential barriers at its output, with the gate biased by a DC voltage.

This is removed by an implement which has a groove of the same cross-section as the thread, at the bottom of an open slot at one side of the implement. A similar groove of larger dimension is at the top of the slot. This is used to remove warp threads (4a) without causing damage to the thread. It is moved to the angular position (26) or (31), and drawn away by a hook (2). The seam is completed, pref. using supplementary threads (6) in the direction (A) from the seamline (3) of the woven structure (7). ADVANTAGE - The seam is c.f prior art and without using specialist appts. The cloth is held as it was woven, and sepd. singly, to reassemble in the correct sequence.

This is repeated for different directions of the bipolar gradient pulse and the phase curves analysed using a fit method. The coefficients of the spherical harmonic functions describing the field distribution are derived from the resulting polynomial coefficients and the associated shim coil currents determined. ADVANTAGE - Enables shimming of magnetic field of nuclear spin resonance equipment with very high degree of homogeneity achieved in short time.

Patent DE-4232117-A1 (DE)
Inventor: VANHEERTUM RUDOLF DR
IPC: C04B41/48
Filed: 1992-09-25
Abstract: The invention provides a process for preparing a suspension of cyanuric chloride in an aqueous liquid (fluid), in particular water. Cyanuric chloride melt is sprayed using a spray device having a spray nozzle immersed in the aqueous liquid. Blockages in the nozzle during the critical running-up (starting) and running-down phases are avoided by passing, before and after spraying, superheated steam through the parts of the spray device coming into contact with cyanuric chloride melt. A particularly reactive cyanuric chloride suspension is obtained by spraying a mixture of cyanuric chloride melt and superheated steam. <IMAGE>

Title: Assuring a required final temperature of pipes rolled from pipe blooms - with reheating taking place between the descaling unit and the cooling bed
Inventor: DEDECKE DIETRICH DIPL ING
IPC: B21B45/00
Filed: 1992-10-02
Abstract: The method for assuring a required final temperature which is constant over the rolling length, and is above the crystallisation temperature AC3 of pipes rolled from pipe blooms in a drawing-reducing mill consists of reheating the pipe blooms/pipes. Reheating takes between a water-spray descaling unit, which is located before the drawing-reducing mill, and a cooling bed located after this mill. It depends on the temperature of intermediate heating installation in front of the descaling unit, the rate and temperature of water used for descaling, the roll temperature and the rolling speed, as well as on the dimensions of the finished pipe. Reheating takes place between the first and last stands of the drawing-reducing mill. Alternatively, the finished pipes are reheated immediately after they leave the mill. The reheating process is carried out by means of an induction coil. USE/ADVANTAGE - In pipe manufacture. It allows required strength, yield point and strain capacity of finished pipes to be attained.
