Title: Process for preventing polymer deposits during polymerization of monomers comprising ethylene bond
Inventor: SHIMIZU TOSHIHIDE
IPC: C08F2/00
Filed: 1989-08-18
Abstract: A method of preventing polymer scale formation in a polymerization vessel during the polymerization of a monomer having an ethylenically double bond, wherein said polymerization is carried out in a polymerization vessel in which its inner wall surface has been previously coated with a coating solution containing (A) at least one member selected from the group consisting of particular anionic dyes, and alkali metal salts and ammonium salts of a sulfonated product obtained by sulfonation of a condensate of a particular aromatic amine compound with a particular aromatic nitro compound, and (B) a particular cationic dye and having a pH of more than 7, and then dried to form a coating. This method can effectively prevent scale formation in the polymerization of extensive monomers having an ethylenically double bond, so that 100 or more polymerization runs can be repeated without formation of polymer scale.

Title: Process and device for producing sweets with two fillings, with the central filling being a granular one, and product obtained
Inventor: RIZZI ROBERTO
IPC: A23G/
Filed: 1990-05-31
Granted: 1994-07-08
Abstract: The sweet has two fillings: a pasty one and an inner granular one. The process involves feeding in the two fillings - an inner granular one and a pasty or liquid one around the granular one - concentrically but separately: the first via screw feeder means and the other via pump means into a probe, up to a point where they meet and with a sugary outer coating intended to form the shell of the sweet. The special feature of the device is that the probe it uses to extrude the two fillings is made up of an internal structure designed to pump the granular products via a screw feeder, and of an external annular structure designed to convey a second creamy or liquid filling pumped from a different supply site, the said probe structures being separated by a leaktight gap with high thermal insulation. <IMAGE>

Abstract: The detector element (R) is a spiral of fine Pt alloy wire in a bridge network comprising two fixed resistors (R1,R2) and two variable resistors (P1,P2) one (P1) of which is first set in the absence of gas to give the experimentally optimum voltage across the detector (R). The other variable resistor (P2) is then adjusted to set the cathode of a first diode (DS1) below its threshold voltage for a predetermined concn., with two further diodes (DS2,DS3) holding two transistors (TR1,TR2) cut off so that a relay (RL) is de-energised. Gas concn. above the preset level then provokes a voltage variation for rapid switching of the transistors and relay.

Abstract: A bottle cap of the tear-off type, particularly an easy-to-open cap for wide mouth bottles, in which a central top wall which covers the top portion of the mouth of the bottle is connected to a lateral band which surrounds the opening of the neck of the bottle and is bent under the edge of the neck to grip the cap, and a tear-off tab, bounded by one or more score lines, extends from the top wall through the lateral band and an angular sealing is interposed between the mouth of the bottle and the top wall and the lateral band. The angular sealing is bonded to the undersurface of the central top wall at a bond area inside the score line or lines, whereby, when the cap is broken by lifting the central top wall by means of the tear tab, the angular sealing is lifted with the central top wall in one piece and slips off from underneath the lateral band thereby freeing or loosening the lateral band from the mouth of the bottle.The sealing can also be bonded to the tear tab at the area bounded by the score line or lines towards the lateral band, to make the lifting of the sealing itself along with the central top wall easier, without breaking it.

IPC: D21C9/10
Filed: 1989-09-18
Abstract: The invention concerns a procedure for the bleaching of pulp using oxygen as an oxidating bleaching chemical. The essential features of the invention are that oxygen is used in the first oxidation stage of the bleaching process, that the pulp is subjected to enzyme treatment, and that after oxygen bleaching and enzyme treatment, the pulp is washed. According to the invention, the subsequent oxidation stages can be implemented using bleaching chemicals containing chlorine, e.g. chlorine gas and/or chlorine dioxide. The use of enzymes allows partial burning of the washings and enables the amounts of toxic compounds in the spent bleach liquor to be reduced, simultaneously lowering its chemical oxygen demand.
