Patent EP-0425555-A1 (EP)
Inventor: MILLAR ROSS WOOD
IPC: C07D303/16
Filed: 1989-07-14
Abstract: Un procédé de préparation d'un ester de nitrate d'un alcool époxyde consiste à faire réagir un alcool époxyde avec N2O5 dans un solvant ordinaire à une température comprise entre -10°C et -40°C, après quoi l'on trempe le mélange de réaction dans une solution aqueuse. La trempe sépare les coproduits d'acide nitrique et d'ester de nitrate en phases aqueuse et organique respectivement afin d'empêcher une réaction ultérieure entre les deux. On supprime la réaction entre le coproduit d'acide nitrique et le réactif d'alcool époxyde produisant des contaminants acycliques, en ajoutant l'alcool époxyde au N2O5 excédentaire, transformant ainsi rapidement l'alcool disponible en ester de nitrate.

Abstract: An optically powered sensor arrangement comprises a plurality of sensors which are interconnected to an optical bus to communicate with a central controller. Each of the sensors receives optical energy from the bus (16) and uses a photo-diode array (52) to convert the received optical energy into electrical energy which is stored in a capacitor (54). Each sensor includes a transducer in the form of a capacitance device (40), such as one in which the capacitance varies with liquid level. In addition, a fixed reference capacitance (44) is provided. Under the action of a timing and sequence control (60), and as energised by the stored electrical energy in the capacitor (54), a pulse encoder (42) produces, in sequence, two integrated outputs, one dependent on the capacitance value of the transducer (40) and the other dependent on the capacitance value of the reference capacitor (44). The integrated outputs are compared with predetermined fixed levels so as to produce a series of short-duration pulses from whose time separation the capacitance value of the transducer (40) can be derived, and thus the liquid level. These pulses drive a light emitting diode (48) to produce corresponding optical pulses which are transmitted to the central control.

Abstract: This invention is to provide a ceramic sliding bearing which is possible to support the axis to which the radial load and the thrust load are applied simultaneously or selectively, and also this invention is to provide a bearing having a small number of parts by constructing the inner and the outer rings by means of ceramics. 
     The ceramic product of this invention is characterized by combination of the ceramic inner ring (1) and the ceramic outer ring (2) wherein said ceramic inner ring (1) which forms an axial hole (4) for engaging the axis at the center thereof, forms a cylinder surface (1a) parallel to the axial center of the axial hole on the outer periphery thereof and forms an approximately rectangular plane to the axial hole at the end portion thereof, and said ceramic outer ring (2) having a cylindrical surface (2a) at the inner periphery which contacts slidably with the outer periphery (1a) of the ceramic inner ring (1) and a plane (2b) which contacts slidably with a plane (1b) formed at the end portion of the ceramic inner ring (1) connecting with said cylindrical surface. 
     The axis is engaged with the axial hole formed at the inner ring, the sliding does not happen between the axis and the inner ring. Accordingly, there is no fear of occurrence of the abrasion to the axis even after long period of use. 
     Since the inner and outer rings are constructed by ceramics, the sliding friction is small thereby being able to   decrease the heat generation due to the friction. Further, since the expansion due to the heat is small, the generation of stress regarding a machine frame and axis, etc. is possible to decrease.

Abstract: 5 n 7  Labels in sheet form are first separated into strips along spaced parallel perforation lines extending in the direction of sheet movement and then into individual labels along spaced perforation lines extending in a direction transverse to sheet movement. The strip separation step can be accomplished with one of three ways. The first embodiment includes a two driven pressure rollers (20) and (22) one of which (22) has a resilient exterior surface including discontinuous alternating larger and smaller diameter areas and the other (20) has a rigid continuous surface of different diameter sections. The rollers cooperate to clamp the sheet at points between the perforation lines as it moves and exert to a force along the perforating lines to burst same. The second embodiment involves moving belts which clamp the sheets between the perforation lines as it moves, gradually separating into different planes. The third embodiment includes a reciprocating element with fins and a pressure pad with slots aligned with the perforation lines to accomodate the reciprocating fins. Transverse separation is accomplished by first and second spaced pairs of rollers. The second pair of rollers is rotated at a higher speed than the first pair such that the labels are completely separated. The individual labels can be accumulated on a slowly moving conveyor.

Abstract: Process for controlling residual free chlorine in drinking water, characterised in that the control is performed by introducing a quantity of chlorine which is determined as a function of the "head" chlorine demand, that is to say upstream of the water treatment or storage line, while obtaining in the distribution system water whose residual free chlorine content reaches the target value. The chlorine demand of the water at the entry of the treatment or storage line is determined rapidly, while accelerating, by heating, the reactions linked with the disinfection, so as to obtain within a short period of time (approximately 5 to 10 min) a water whose residual free chlorine content corresponds to the required value. A certain number of analyses of raw water to which increasing doses of chlorine are added are carried out successively to measure the residual free chlorine. The value of the latter is recorded in a memory for each test carried out as a function of the quantity of chlorine introduced. The chlorine demand curve is plotted with the aid of a graphic software. The chlorine concentration to be introduced into the water is defined by virtue of this curve as a function of a fixed free chlorine value used as a target value.
