Abstract: Abstract of the Disclosure A speed control apparatus for sensing over speed conditions of a vehicle.  A signal source which produces signals at a frequency which are proportional to vehicle speed feeds an electronic high pass filter whose cut-off frequency is variable and settable to a frequency which is proportional to the predetermined speed above which an over speed condition exists.  A relay driver is operated in re-sponse to signals passed by the electronic high pass filter to operate a relay.  In order to check the cut-off frequency of the high pass filter, a check oscillator is provided which is turned to a frequency slightly in excess of the desired cut-off frequency of the high pass filter.  The relay driver operates an electronic switch which intermittently provides the signals from the check oscillator to the elec-tronic high pass filter.

Abstract: ABSTRACT:     Two six-pole annular magnetic structures are arranged about the neck of a three-in-line colour display tube so as to be eccentric with respect to each other and with respect to the centre of the neck. The centre of one six-pole is situated halfway between the central electron beam and one outer electron beam. The two beams on both sides of the centre of the six-pole, consequently,are subjected to equal forces of the same direction.      The third beam is subjected to a force in the same direction, but this force is nine times larger due to the three times as larger distance from the centre of the six-pole and due to the square-law field variation thereof. Because of their identical direction and value, the forces acting on the former beams will not disturb the convergence therebetween.

Abstract: Abstract of the Disclosure A marine riser including a uniquely designed three element connection structure and associated connecting a. ? releasing means for the inhibiting of fatigue failure caused by moments and axial loads resulting from relative motion between the fixed ocean bottom and a floating drilling platform or ship, such as  a semisubmersible rig.  The system includes a preloaded connection including a female member and a male member coaxially aligned and held in compression by a nut placed in tension.  The connection holds riser pipe sections together.  The connection is preloaded through a tool to a degree such that when a load equal to the yield strength of the pipe section material is applied to the pipe sections joined by the connector, the compressed faces of the male and female members do not separate from each other. The degree of preload would be sufficient to maintain the contact between the compressed faces under expected working loads of the pipe sections.  The tool operates in conjunction with lugs located on the nut and a flange or platform with mounting holes located on the male member.  A lock is provided on the nut to prevent the disengagement of the male and female members after they are brought into compression by the nut.  The position of the lock relative to the nut lugs determines the sustained preload of the connection.  Seals are provided between the male and female member to prevent leakage of fluid between the interior of the riser connector and the surrounding environment.  The connector also includes provision for the support and connection of sections of kill and choke lines.
