Title: Improved Process for the Recovery of Sulphate of Potash (SOP) from Sulphate Rich Bittern
Inventor: PARIMAL PAUL
Filed: 2006-03-05
Granted: 2011-02-27
Abstract: The present invention relates to a novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern. The process requires only bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern. Kainite is converted into schoenite with simultaneous removal of NaCI in a single step and the filtrate (SEL) is used for production of KCI. The schoenite is reacted with aqueous KCI to yield SOP and the filtrate (KEL) is recycled in the kainite to schoenite conversion step. The production of KCI from SEL is carried out with the aid of DPA. Lime is treated with DPA in water for the production of highly soluble Ca(DPA)2, which in turn treated with SEL to produce insoluble K(DPA) with >95% yield. The isolated K(DPA) is treated with 1:1 HCI to produce KCI and insoluble DPA, which can be recycled for the production of Ca(DPA)2. The aqueous KCI thus obtained is treated with schoenite to prepare SOP, purity 90-92%: The KEL obtained along with SOP is recycled to generate schoenite. Utilisation of all effluent and intermediate streams allow for an overall SOP yield >89% w.r.t. the potash content in the mixed salt.

Title: Ink-jet printing device
Inventor: BARBERO AQUILINO
IPC: B41J2/155

Granted: 1988-10-14
Abstract: The device has an electrically insulating ink container containing one electrode and a counter-electrode disposed adjacent to the jet nozzle which is laser-bored through the container cover plate.  The two electrodes are excited by a voltage pulse such as to generate a spark between the ink meniscus and the counterelectrode, and to expel ink particles, rather than a single blob. The ink can be kept in circulation between the container and a reservoir by a pomp.  The meniscus can be kept outside the nozzle by a second nozzle coaxial to the first, or by a suitable arrangement of the ink hydraulic circuit.  In the case of magnetic ink, the meniscus is pulled back by a magnetic field.  The ink can also be brought in front of the nozzle by capillarity.

Abstract: The magnetic recording and reproducing system of helical scan type sequentially records four types of pilot signals of different frequencies, one for each field of a TV signal, in superposed relation to the TV signal. During normal reproduction, at the same speed as used in recording, two frequency signals are generated representing the frequency difference between reference signals and the pilot signals reproduced from  adjacent tracks on both sides of the main track. The level difference between the frequency signals represents a tracking error which is used to control the relative position of the rotary head and the recording track.

Title: Frequency detection circuitry
Inventor: LEE BYUNG-JO
IPC: H03K5/00

Granted: 1992-03-23
Abstract: The  detector  clears  a  counter  at  the  noise  frequency relatively high and low compared with  the  target  frequency  and enables  the  counter  at  the  target  frequency.  The   detector comprises an input signal detector (1) for detecting tip  or  ring signal transmitted through  telephone  lines  and  for  generating rectangular pulse having some Hysteresis width,  a  differentiator (2) for differentiating the rectangular pulse and  for  generating positive differentiating pulse, a comparator (3) for comparing the positive pulse with reference voltage (Va) and for  comparing  the compared value with charge discharge  pulse  (V2)  to  output  the frequency between two reference voltages (Va,V2),  and  a  counter (4) cleared or enabled according to the output signal of the input signal detector (1) and the comparator (3).
