Patent EP-0049925-A3 (EP)
IPC: E02F3/30
Filed: 1981-10-05
Abstract: Such excavator comprises a supporting column (1) of 
structural cross section, a hydraulic pump (2) and associated 
control box (13) for feeding the hydraulic system, a motor (3) 
driving said pump (2). an articulated arm (4), a working tool 
(5) and a control system (6) for the arm (4) and the tool (5).  
     A pivot (11) extending with its axis parallel to the vertical 
longitudinal axis of the column (1) is mounted on the 
projection (1d) of the column (1) and the articulated arm (4) is 
secured by means of the hinge (16) to the pivot. Such pivot 
(11) permits the articulated arm (4) to be rotated through 180° 
about the axis of the pivot. The hinges (16) also permit the 
articulated arm (4) to be lifted.  
     The working tool (5) is mounted at the distal end of the 
portion (4b) of the articulated arm (4). All rotary movements 
of the articulated arm and its portions as well as the working 
tool are hydraulically controlled by means of hydraulic rams 
(12, 4c, 4d and 5a).  
     The motor (3) is an electric motor or an internal 
combustion engine and may be located adjacent the column 
(1) or outside the well (21).  
     The column (1) is secured by means of the brackets (7) to 
anchoring means (8) or by means of the guide (1a) to a rail on 
(20) of the well (21).  
     In this manner the excavator can perform its excavating 
work within the well by penetrating gradually more and 
more thereinto as the depth on the well increases. A plurality 
of anchoring means or rails may be mounted at the same 
depth of the wall of the well to give the excavator a range of 
maneuvrability of 360°.  
     This excavator permits to make vertical or inclined wells 
of any cross section and shape, particularly wells of small 
diameter or of oblong cross-sectional shape which cannot be 
made by conventional excavators.  
     Further, this excavator is particularly useful for excava­
tions under difficult working conditions such as in places that 
are not easily accessible or cannot be easily supplied with 
electric power.

IPC: B29C71/00
Filed: 1987-01-20
Abstract: A method for producing a formed product such as a 
sheet or film of a polyarylenethioether having increased 
crystallinity is provided. The method comprises 
contacting a molded product of a resin containing an 
effective amount of a polyarylenethioether including not

an organic substance having an SP value of 8 to l2 at a 
temperature of not lower than the solidification point of 
the organic substance and not higher than the melting 
temperature of the resin for a time sufficient to obtain

product with the organic substance and then subjecting 
the formed product thus treated to heat treatment in the 
substantial absence of the organic substance. According 
to this embodiment, the crystallinity can be markedly 
enhanced in the same treating period of time.
