Patent IT-1211136-B (IT)
Title: Metal joints formation by brazing
Inventor: GEROSA LUIGI
IPC: B23K/
Filed: 1981-11-25
Granted: 1989-09-29
Abstract: The circuit has a switch coupled to a source of a voltage supply and has a control input responsive to a signal that is indicative of when electron beam current cut-off is required and related to a deflection signal for the electron beam for selectively conducting a current associated with electron beam cutoff. A capacitor is coupled to the switch and to a control grid of the cathode ray tube for storing a charge to develop an electron beam blanking voltage on the capacitor. The switch conducts the current related to electron beam cutoff when electron beam current cut-off is not required and disables conduction of the current related to electron beam cutoff when electron beam current cut-off is required. The capacitor is charged from the current related to electron beam cutoff that flows through the switch and is supplied by the source of the voltage supply when electron beam current cut-off is not required. The switch decouples the source of the supply voltage from the capacitor and places the blanking voltage developed on the capacitor across the control grid when electron beam current cut-off is required to cut-off the electron beam current in the cathode ray tube.

Title: Electrostatographic toner contg. an alkyl pyridinium cpd.
Inventor: CHIN H LU
IPC: G03G/
Filed: 1979-10-30
Granted: 1986-05-14
Abstract: An electrostatographic toner comprises a resin, a pigment, and an alkyl pyridinium cpd. or its hydrate of formulae (I) and (II) respectively: R is a 8-22C, pref. 12-18C, hydrocarbon radical, and A is an anion, pref. halide, sulphate, sulphonate, nitrate or borate. The toner can be used in a reverse system and provides a positively charged toner which gives high quality images over a longer period of use than prior art toners. It is resistive to moisture leaching and gives images which transfer to plain bond paper without blurring. The cpd. is completely compatible with the resin and provides toners with improved particle-to-particle uniformity and narrow charge distribution.

Granted: 1989-11-30
Abstract: The apparatus has an X-ray source (3) having an electron source (31) and a stationary anode (4) which describes a full or partial anode ring with a circuit for accelerating electrons emitted from the electron source, using a high positive constant voltage, towards the anode ring. The electrons form an electron beam (32) which collides with the anode ring at a focal spot (41) which, in turn, emits X-ray radiation in the form of a fan beam (42). With a full or partial X-ray detector ring (5) the detector ring and the anode ring are coaxially arranged and define a scan slice. The detector ring is such as to permit the spatial resolution around the ring of the X-rays detected. A number of electron sources are arranged on an electron source ring (33) in proximity to the anode ring. A circuit is provided to control the sources individually in order to emit electron beams in set time sequence. The focal spots produced by the electron beams on the anode ring are each electromagnetically swept over a portion of the anode ring.

Title: Glass-ceramic of cordierite type - from materials contg. oxides of magnesium, aluminium and silicon with addition of nucleating agent
IPC: C03C/
Filed: 1975-08-05
Granted: 1985-05-08
Abstract: Prodn. of glass-ceramic of the cordierite type by melting together starting materials contg. MgO, Al2O3 and SiO2, chilling the melt to effect solidification of glass, heating the glass to form cordierite-type crystals embedded in a glass phase, is improved by introducing into the material up to 3 wt. % of a nucleating agent selected from Mo, Ta, Zr, Ng, Ti, Li and/or As, or their oxides, or cpds. capable of liberating the oxides at elevated temps., or LiF. Pref. the solid glass is comminuted (particle size =0.004 mm), mixed with a comminuted nucleating agent, and the mixt. is heated at a temp. at which cordierite-type crystals surrounded by the glass phase are formed. The cordierite crystals should have the formula 2MgO.2Al2O3.nSiO2 (n = 5-8, pref. 5) These refractory materials are suitable for high-temp. application e.g. in gas turbines, for applications, involving temp., fluctuations such as heat exchangers, for other purposes, e.g. in radar construction. The coefft. of thermal expansion is low (1.60 x 10-6 degrees C-1) due to the high content of the cordierite-type crystals (>=80 wt. %). The preliminary grinding of the glass, mixing it with comminuted nucleating agent and heating the mixt. results in uniform formation (throughout the whole material) of a great number of small cordierite-type crystals. High mechanical strength can be achieved.
