Filed: 1985-11-29
Abstract: 1. Process for the preparation of pure dialkyl succinates by catalytic hydrogenation of derivatives of maleic acid and/or fumaric acid, characterized in that the catalytic hydrogenation is carried out on the corresponding undiluted dialkyl maleates and/or dialkyl fumarates, which are in the liquid state of aggregation, at temperatures of 40 to 190 degrees C, with the proviso that the reaction temperature stabilizes above the melting point of the starting material which is used, and under a pressure of 1 to 40 bar.
Patent EP-0165058-A3 (EP)
IPC: H04B10/00
Filed: 1985-06-12
Abstract: An optimized full duplex light wave communication 
system having a base unit and a portable unit. Two 
continuously operative channels exist between the base and 
portable units for two way communication at frequencies 
selected to minimize interference despite the presence of 
light within the environment of use at both frequencies. In 
addition, photo emmiters and sensors are specifically confi­
gured in an assembly to minimize cross talk between sensors 
and emitters. A closed loop is formed around the two 
communication channels that it is operative to regulate the 
intensity of illumination received at the base photo sensors 
to a constant level that provides quality audio communica­
tions and minimize portable unit battery drain. The closed 
loop additionally causes base station transmitter frequency 
tracking of any center frequency variation in the portable unit 
receiver.

Patent EP-0195759-A3 (EP)
Title: Contact end for a welding electrode
IPC: B23K9/28
Filed: 1986-02-12
Abstract: A contact tip for supporting a consumable welding electrode and for supplying welding current thereto. The contact tip is generally rod-shaped and has a passage with a helical contact surface. The welding electrode is fed through the passage and makes electrical contact with the contact tip. Because of the helical contact surface, the passage never becomes constricted by cumulative deposits of dirt and extraneous matter from the welding electrode surface. Also, the helical contact surface, which axially extends at least one complete turn, has an unbending effect on the welding electrode, thus straightening the electrode. A distance "A" of the electrode axis from the contact tip axis may be chosen, as desired, considering the diameter of the welding electrode. Optionally, the contact tip may include a sleeve-like nozzle, to shield the contact tip from deposits of welding splatter.

a chamber (26) formed by side walls (14,16) and 
a cylindrical outer wall (18). The side walls having 
aligned openings (22,24) therethrough which are 
on the longitudinal axis of the outer wall (18). 
A refractory tube (34) which is adapted to contain

(22,24) and across the chamber (26) in the housing. 
The portion of the side walls (14,16) of the chamber 
(26) adjacent the openings (22,24) are closer together 
than the remaining portions of the side walls (14,16) 
so that the chamber (26) has a first portion (30) 
around the refractory tube (34) which is narrower 
than a second portion (32) of the chamber around 
the first portion. A coupling loop is electrically 
coupled to a side wall (16) of the chamber (26)

in which the plasma formed in the refractory tube 
(34) is very short for increased power and greater 
brightness of the plasma. This also provides a 
resonant cavity which requires no tuning and is 
more stable.

Title: Self-adjusting steering mechanism for borescope, endoscope, or guide tube
IPC: A61B1/005
Filed: 1988-07-26
Abstract: In a cable-steerable endoscope, borescope, or guide tube 
in which opposing cables (34, 36) are displaced to deflect the tip of the 
instrument, a self-adjusting mechanism in the control section 
ensures that a maximal differential force and a minimal total 
force is applied to the two steering cables (34, 36). The self-adjusting 
mechanism has a frame (52, 53) that is affixed within the control section 
and a slider plate (56) that is slidably disposed on a longitudinal 
rail (54) of the frame (52, 53). The slider plate projects outwardly to 
engage ends of the cable sheaths (42, 44) for the steering cables. The 
slider plate engages the frame rail (54) when there is force on only one 
steering cable to lock the slider plate against sliding motion. 
When there is no force, or equal forces on the steering cables, 
the slider plate moves proximally on the frame. This 
arrangement, along with a reset spring, automatically takes up 
unneeded play or slack in the cables and also avoids the 
simultaneous tensioning of the two cables that can produce high 
steering forces and that can damage the steering section.
