Title: Hydraulic winch derrick swinging mechanism - has two winches aligned to pull derrick to one side, driven by common supply
Inventor: HAGENES HARALD
IPC: B66D1/26
Filed: 1977-12-14
Abstract: The hydraulic unit system for swivelling a derrick has two winches so aligned that they pull the derrick to one side. They are controlled by a manoeuvring valve (2) and are driven by a common hydraulic supply (3). The pressure sides (1) of the two motors are connected to a common hydraulic supply (12) which supplies a somewhat higher pressure than the maximum pressure at the take-off sides (4) and (5) of the two motors. To swivel the derrick, pressure medium is fed from the hydraulic supply (12) to the motor which pays out so that the moment on this is reduced. Consequently, the other winch can pull the derrick to its side.

Inventor: TAKADA MASAHIRO
IPC: F28F9/22
Filed: 1978-07-13
Abstract: Fixed-bed shell and tube heat exchange reactor for exothermic catalytic vapour phase oxidn. comprises a bundle of reaction tubes filled with an oxidising catalyst and located in a shell. The tubes extend through apertures in a perforated shield plate which divides the shell into two heat transfer medium feed zones.

Used for oxidn. of hydrocarbons, esp. naphthaline or o-xylene to phthalic anhydride and ammonoxidation of aromatic hydrocarbons into aromatic nitriles. Heat distortion of the shield plate and tubes is prevented because the tubes and shield pate do not contact one another. The design of the reactor permits the temp. difference between the two heat transfer zones to be maintained at 0.100 degrees C.
