sockets should be crippled. This means that the weakest spot in the wireline needs to
be at the point of attachment to the tool, so that the line may be pulled free of a stuck
tool and recovered by its winch.
Wireline tools should be fitted with a fishing neck so that they may be
recovered with a normal fishing assembly. A sonde containing a radioactive source,
an unusually expensive tool, or a tool lost in a washout or large diameter hole should
not be treated in this manner. Although this method is more complex and takes much
longer, it is more likely to recover the fish.

The Infinitive
The infinitive is a verbal form (a non-finite verb form) which consists of the
base form of the verb with the particle "to": to do; to go; to play; to take; to break; to
find.
The English infinitive and the Russian non-finite verb form have similar
features. At the same time, the infinitive in English has a number of peculiarities
which make using the infinitive difficult for language learners.

Properties and functions of the infinitive
The infinitive has some properties of the verb. The infinitive names an action

(to drive a car) or state (to be sick), but cannot show person, number, or mood. The
infinitive has active and passive forms (to take; to be taken) and can express voice
and time, though in a rather limited way.
The infinitive can have a direct object (He plans to visit a museum) or a
prepositional object (He wants to know about it) and can be modified by an adverb
(He tried to walk slowly).
The infinitive can be part of the compound verbal predicate (She can drive; We
must go) or part of the compound nominal predicate (His aim is to help you). The
infinitive alone, without another verb, is generally not used as the predicate.
The infinitive has some properties of the noun and can be in the function of the
subject (To quit now would be a mistake) or of an object (He likes to sing; She asked
me to wait). The infinitive can be in the function of an attribute (He has no desire to
see them).
The infinitive can function as an adverbial modifier of purpose (He came here
to study) or as an adverbial modifier of consequence (He was too tired to go to the
cinema).
Use of particle "to"
As a rule, the infinitive is preceded by the particle "to".
The particle "to" is omitted after modal verbs (You can go; You must take it),
after the verbs "make, let" (Make him eat; Let her play), after the verb "help" in
American English (Help me find my book), and in constructions like "She saw him
leave; He heard her sing". The infinitive without the particle "to" is called bare
infinitive.
If the verbs "make, help, see, hear" in such constructions are used in the
