This expression, except for the mechanical design, is totally independent of the type of start and the electrical design of the motor. Electrically also, this is demonstrated in I he subsequent example. The expression, however, does not hold good for an ON-LOAD start. On load, the accelerating torque diminishes substantially with the type of load and the method of start, as can be seen from Figure 2.14, and so diminishes the denominator of equation (2.5), raising the time of start. [Pg.44]

It monitors and displays the starting conditions such as time of start and number of starts etc. [Pg.294]

Likely settings - 6 versus tripping time, or time of start versus tripping time—whichever occurs first. Likely features - an advance alarm and an indication before a trip. [Pg.297]

Within a short time of starting Halcion, rebound begins to dominate the clinical picture, and insomnia worsens. Nishino et al. (1995) observed that short-acting BZs were initially preferred for elderly patients. They remarked, However, it has since been found that short-acting BZs induce rebound insomnia (a worsening of sleep beyond baseline levels on discontinuation of a hypnotic), rebound anxiety, anterograde amnesia, and even paradoxical rage. ... [Pg.337]

Pancreatitis has been noted with mesalazine often enough to be taken seriously (66) it usually occurs within a short time of starting treatment, has occurred in children as well as adults, and has sometimes been confirmed by rechallenge (SEDA-18, 375). [Pg.142]

All the values allowing an accurate evaluation of the endpoints (toxicity and clinical response biomarkers, surrogate endpoints, or clinical endpoints). Treatment data, for example, dose and actual times of start and end of infusion. [Pg.794]

At the time of starting the robalzotan project, a well-developed process to prepare the forerunner ebalzotan was already in hand to a level that allowed the production of multiple kilograms of all intermediates, inasmuch as the starting material was freely accessible. Not surprising then that the search for a feasible first synthesis of the new target compound attempted to build on as much as possible of the experience and knowledge that was previously achieved. Racemic aminochroman... [Pg.113]

Modem relays combine the 46, 49, 50, 51 N and 86 functions together with others such as motor stalling, number of starts, thermal state at the time of starting, undercurrent, overloading, high-set current limit. [Pg.535]

Single-shift scheduling is stUl used in many situations. The shift is called a day shift, whether a person starts at 7 a.m. or 3 p.m. Schedules can be made for people and the time of starting can be determined later. The more interesting situation is a seven-day-a-week operation, with people being scheduled to work eight-hour shifts for an average of five shifts per week. [Pg.1746]

In the industrial o allization, operation design which satisfies required product specification is also important. However, methods of determining the seed crystals specifications i.e., size distribution and mass of seed cr3 tals, and the time of addition have not been considered systematically. The required time of start-up operation is known to be different by 10 residence times even in the laboratory scale depending on the seed crystals specifications(2). In the present study relations between the procedure and conditions of start-up operations and the product crystal size distributions are discussed based on the analysis of product crystal size distributions. The purpose of this study is, therefore, to obtain design strategies for start-up operation by use of a typical MSMPR (Mixed-Suspension Mixed- oduct Removal) crystsdlizer which has been used for the theoretical analysis. The ammonium-sul te water system was used. [Pg.172]

The new objectives set by the Phenix power plant have led to an increase in operating life beyond the period originally planned at the time of start-up. In order to extend operations, the CEA has undertaken power plant renovation, based on the following ... [Pg.84]

The extent of conversion is a measure of fractional conversion of reactants achieved in a specified time. Let and be the initial number of moles of A and B, respectively, present in the reaction vessel of volume V. Let nJ and Hg be the number of moles of A and B, respectively, present in the vessel after some time t. The extent of conversion or fractional conversion of A is defined as the number moles of A converted in a specified time per moles of A present at the time of start-up. Thus,... [Pg.10]
