Horizontal split head
|
An internal defect that occurs within the head of rail. it is a progressive longitudinal fracture in the rail, where separation along a seam spreads horizontally through the head, parallel to the running surface. it may curve upwards or downwards before breaking. the origin of this defect is an internal longitudinal seam, segregation, or inclusion. this may be seen generally by a widening in the top of the rail head. a horizontal crack will eventually start to form on the sides of the rail head. this defect can result in a long section of the rail head falling out and can occur throughout the rail and therefore result in multiple breaks.

Longitudinal, английский
- Generally parallel to the direction of the wood fibres.
- Продольный
- Generally, parallel to the direction of the wood fibers.
- Продольный, относящийся к долготе, стрингер
- [1] extending in the lengthwise direction, as distinguished from transverse. [2] said of any fore-and-aft structural member, such as a frame or bulkhead.
- Running lengthwise.
- Along the length of a structure.
- Direction parallel to the long axis of an object and perpendicular to its radius — for example, down the length of a cylinder. compare circumferential; radial; transverse. lot tolerance percent defective (ltpd): the poorest quality, in percent defective, individual lot that is acceptable in a sampling plan. ltpd is the percent defective that will be accepted by the sampling plan at most 10 percent of the time. with such a plan, the producer agrees to supply just enough nonconforming product such the consumer will accept the lot using the agreed to sampling plan and acceptable quality level. compare acceptable quality level. lumen (lm): si photometric unit of luminous flux, weighted according to the photopic vision response. one lumen equals the light emitted by one candela (cd) point source into one steradian (sr) solid angle (1 lm = 1 cd/sr).
Separation, английский
- Разделение, отделение; эшелонирование; интервал эшелонирования
- Отделение, разделение; эшелонирование; интервал эшелонирования
- The development of layers of paint of different composition in a can during storage when the materials are not completely soluble, miscible, or stable.
- The act of separating or dividing two or more people or things, or the state of being separated

Segregation, английский
- Ségrégation
- Separation, especially of races.
- 1. the act of separating one person, group or thing from others, or of dividing people or things into separate groups which are kept apart from each other 2. the separation of the alleles of each gene and their distribution to separate sex cells during the formation of these cells in organisms with paired chromosomes

- Where a metallic constituent which cools last, forms a final brittle film between crystals. it may also be a concentration of non-metallic impurities. segregations may occur at the center or be grouped in some regular form about the center.
- In manufacturing, nonuniform distribution of alloying elements, impurities, or microphases. self-emulsifiable: see penetrant, water washable.
Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a

Vertical split head, английский
An internal defect that occurs within the head of rail. it is a progressive vertical fracture in the rail, where separation along a seam spreads vertically through the head, parallel to the side of the rail. this is a serious defect because it can— (a) result in a long section of the rail head falling out; and (b) occur throughout the remainder of the rail and therefore result in multiple breaks. detection is by visual observation of widening in the top of the rail head, or the dropping of one side of the rail head.
Local control panel, английский
- An interlocking machine that may be switched to and from local control, but is capable of being switched to remote control.
- Местная панель управления
