Head note

An abridged copy of U.S. Patent No. 5,131,727 is provided in Figure 1 to illustrate the elements of an issued U.S. patent. The covet or front page of a U.S. patent (Fig. la) must foUow the form requinements placed on issued patents by the U.S. PTO. Specifically, the front covet discloses the inventor in two locations, A and C. The first named inventor is generally used as a head note. A, for the patent. A given patent may often be referred to in an informal sense by this inventor s name. 

The total suction head. Figure 3-41, is the difference in elevation between the liquid on the pump suction side and the centerline of the pump (plus the velocity head). Note that the suction head is positive when above the... 

The crude episulfone (3.0 g.) is placed in a 10-ml. round-bottomed flask fitted with a reflux condenser and is heated at 95° for 30 minutes, when it decomposes with loss of sulfur dioxide. The reflux condenser is replaced with a distillation head (Note 6), and the yellow residue is distilled under reduced pressure (water aspirator). d -2- Oxo-7,7-dimethyl -1 -vinylbicyclo [2.2.1] heptane... 

The heavier chlorocyclohexanone layer is separated and combined with three 150-ml. ether extracts of the aqueous phase, and washed with 150 ml. of water and then with 200 ml. of saturated sodium chloride solution. After filtration (gravity) through anhydrous sodium sulfate the ether is removed and the residue vacuum-distilled in a modified Claisen flask. The fraction (300-340 g.) boiling below 100° at 10 mm. (Note 5) is collected (Note 6). This material is then fractionated carefully under reduced pressure by means of a 42-in. modified Vigreux column (heated) with a total condensation variable takeoff head (Note 7). The yield of 2-chlorocyclohexanone boiling at 90-91°/14-15 mm. is 240-265 g. (61-66%) (Notes 8 and 9). 

With practice, you can multiply simple matrices in your head.) Note that matrix multiplication is not commutative AB is not necessarily BA, e.g. 

Allen, Ep. 1930. A list of topics jotted down at the end of the draft (see Allen s head-note to the letter) indicates that he wanted to speak about nostra schola, that is, the school Melanchthon had instituted in Niirnberg in 1526. 

The meanings of the symbols employed in the tables, principally in the column headed notes , are given below. 

In a l-l. three-necked flask equipped with a dropping funnel, a thermometer, and an efiicient fractionation column fitted with either a vapor- or liquid-splitting head (Note 1) is placed 400 ml. of mineral oil. The oil is heated to 240-270 and dicyclopen-tadiene (Note 2) is added at the rate of 5-10 ml. per minute. The reflux ratio and the rate of addition of dicyclopentadiene are adjusted to maintain the distillation head temperature at 40°. The cyclopentadiene is collected in a Dry Ice-acetone receiver (Note 3). 

A. N,N-Dimethylcyclohexanecarboxamide. In a 1-1. threenecked flask equipped with a reflux condenser and a dropping funnel, both carrying drying tubes, is placed 128 g. (1.0 mole) of cyclohexanecarboxylic acid (Note 1). Thionyl chloride (179 g., 1.5 moles) (Note 1) is added during 5 minutes to the acid, with stirring by a magnetic stirrer. The flask is placed in an oil bath and heated at a bath temperature of 150° for 1 hour. The reflux condenser is then replaced by a distillation head (Note 2), 200 ml. of anhydrous benzene is added, and the mixture is distilled until... 

Fig. 3 Crevice and pitting corrosion of a stainless steel autoclave head. Note the crevice corrosion underneath the bolts (now removed) and in the gap between the two parts that are still assembled, and the pitting corrosion on the free surface. This corrosion was probably caused by chloride derived from thermal insulation. (View this art in color at www. dekker.com.)...

In large measure syntheses of aglycones have relied on the employment of one (or more) of three general reaction classes Friedel Crafts alkylations or acylations, nucleophilic condensations, and Diels Alder reactions the various routes are conveniently discussed under these three headings. (Note unless otherwise Indicated, all compounds described in the section on aglycone synthesis are racemic.)... 

In an attempt to simplify searching procedures, we have made an effort to minimize the variety of terms used in the matrix heading. However, in a nmnber of cases, the matrix is associated with various key words that can be used to narrow the search. For exEimple, the term formulations has the key words tablets, creams, ointments, and injections associated with it. Thus, to find references applicable to tablets, search first for formulations under the matrix heading and then tablets under the key word heading. Note that the term bulk is used instead of raw materials. Some of the more common matrix terms md their associated key words are given below. 

Perfumers divide these various notes into top, middle and bottom or, more in keeping with the industry image, into head, heart and base. These classifications are based on a combination of volatility and impact of ingredients. The head notes are those which are most obvious on opening a bottle of perfume and the citrus notes, for example, fall into this category. The heart are the medium volatility notes which are responsible for the basic character of the perfume and the base notes are the least volatile notes which help to hold the others back and blend them together. The base notes become more obvious after the rest of the perfume has evaporated. A well balanced fragrance will typically have about 25% head, 50% heart and 25% base. Apart from the fruits, all the... 

Vetiver olli Viscous, brown to reddish brown oil with a heavy, very adherent, earthy, slightly acidic, woody, balsamy odor, often with a fatty-moldy head note. Production By steam distillation from the roots of the tropical grass species Vetiveria zizanioides (Poaceae). Origins Reunion ( Bourbon ), Haiti, Indonesia, Brazil, China, India. The yearly world-wide production is probably about 2001. 

Primary bending stress in head, Note Primary bending stress is maximum at the center of the head. 

This also may be calculated in one s head (note that the spin functions in the square brackets are normalized . 

For example, highly volatile substances are said to display "head notes," those less volatile and usually associated with flowers are said to have "heart notes, and the least volatile ingredients, usually with woody, balsamic, or musklike aromas, are described as "base notes." ... 

The results from experimental determinations of the constant A are presented in Table II. 1 for the following conditions gap between contiguous bodies 4 A no deformation of contact zone contiguous bodies are ideally smooth. In those cases in which the gap between the contiguous surfaces is not equal to 4 A, its values are given in the column headed Notes in Table II. 1 (in the series of experiments reported in [54], the surfaces were rough quartz plates). 

This technology provides relatively good results, however, flexibility is limited due to its structure (and particularly the fibre s large diameter), which prevents its use on hardly curved surfaces, as human head. Note that, according to the authors measurements, the second blanket will raise the skin temperature to 43°C after 10 min of light delivery at 1 W input power (no information is provided for the first blanket).
