Abstract: METHOD AND APPARATUS FOR TOWING ICEBERGS          ABSTRACT OF THE DISCLOSURE          A method and apparatus for towing icebergs.  A hole is augered in the side of an iceberg at a tow point, a expanding base or other type of anchor is inserted into the hole and the iceberg is towed by pulling on a hawser attached to the end of the anchor.  In a preferred embodiment the sea water which entered the hole around the auger is flushed out with fresh water and the fresh water is frozen around the auger or other anchor.  This freezing action creates a bond between the anchor and the iceberg whereby the anchoring point is able to sustain a shearing force equal to the surface area of the refrozen water in contact with the sides of the holes times the shear strength of the bond.

Abstract: IMPROVEMENTS IN SWITCH OPERATING MECHANISMS          FOR HIGH VOLTAGE SWITCHES      ABSTRACT: A three-phase, high voltage switch arrangement is operated through a connected drive shaft by a switch oper-ating mechanism that can be either driven by motor power or manually operated.  When manual operation is desired, a crank handle is folded out of a stored position to an operating position.  An improved mechanism is provided to prevent the crank handle from operably engaging the switch operating mech-anism until stored torsional energy (i.e., the potential energy due to torsional strain) in the drive shaft has been released, thereby avoiding improper operation, such as unexpected whipping of the handle.  In addition, when the crank handle is folded out to its operating position, the motor is disabled so that the motor can not be operated while the handle is engaged with the mechanism so that the handle cannot be driven by the motor.  When it is desired to disconnect the switch operating mechanism from the switch so that maintenance and testing can be performed, a selector handle may be operated that disconnects the drive shaft from the operating mechanism and locks the drive shaft so that the switch cannot be acciden-tally opened or closed due to wind or vibrational forces.  Also, while the selector handle is being operated, the motor cannot be operated while the drive shaft is being disconnected and locked.

Abstract: A compact print wheel position sensing device for parallel-wheel printers includes pairs of optoelectronic printed circuit emitters 22 and receivers 24 arranged in two lines inside and outside, respectively, a tubular shaft 21 provided with radial holes 23 aligned with each emitter/receiver pair and carrying wheels 19 which mesh with corresponding parallel print wheels 11. Each wheel 19 has a set of angularly spaced transparent regions, alternating with opaque regions, which permit transmission between the corresponding emitter/receiver pair at each printing position of the respective print wheel. A logic device includes a memory arranged for storing printing wheel position orders and having double reading heads for each division. A double electronic switch is connected to the heads to read the divisions in numerical sequence, each division being read twice per cycle, the earlier reading head controlling electromagnetic latches for stopping each print wheel at the ordered position and the later reading head subsequently delivering the order signal for comparison with the resulting wheel position, thereby compensating for mechanical actuation delay of said electromagnetic latches.

Title: Vertical synchronization circuit for  television receivers
Inventor: RZESZEWSKI THEODORE S
IPC: H04N5/04
Filed: 1980-06-02
Granted: 1982-10-05
Abstract: ABSTRACT     An  improved   vertical   synchronization  system  for  a television receiver provides both good noise immunity and improved interlace.    This  is acheived by employing two parallel vertical synchronization circuits between the synchronizing signal input of the  vertical oscillator and the synchronizing signal source.  One of these vertical synchronizing circuit paths comprises a standard integrator  circuit  adjusted  for  optimum noise immunity and the other  is  a  cascaded  digital  circuit  adjusted  for   improved interlace but having poorer noise immunity than the first circuit.          The digital circuit produces a synchronizing pulse slightly  ahead of  the  pulse  produced  by  the conventional circuit so that the digital circuit normally controls the operation of the oscillator.          Whenever  extreme  noise  conditions exist, the digital circuit is disabled and the conventional synchronizing signal  circuit  takes o?er the synchronizing task.

Radio-receiver having a frequency-locked loop which comprises, arranged one after the other, a tunable voltage-controlled oscillator, a mixer stage, a filtering element, as well as a frequency-voltage converter which is connected to the tunable voltage-controlled oscillator, several stable tunings being possible for each transmitter. An unambiguous selection is made from these stable tunings of a tuning to a desired station by muting the radio receiver in the other stable tuning frequency ranges. To this end the radio receiver according to the invention comprises a muting circuit as well as a control circuit for the muting circuit in which use is made of a further frequency-voltage converter comprising an all-pass frequen-cy-dependent 180° phase shifting network, a phase detector and a limiter, By adjusting the muting circuit of the radio receiver to the quiescent condition only in the desired tuning range and by activating it outside this range, a suppression of interstation noise is obtained at the same time.

Abstract: ABSTRACT OF THE DISCLOSURE:       The object of the present invention is a new method for fluorometrically assaying the activity of fat-degrading enzymes, such as lipases and phospholipases in samples containing said enzyme, such as in serum.  According to the method the enzyme containing sample is reacted with a subs-trate containing acyl- or alkylglycerols or -phosphoglycerols having at least one fluorescent group, such as a pyrene group.          The compounds may in addition contain fluorescence quenching groups.  The enzyme hydrolyzes the substrate thus giving rise to changes in the fluorescence intensity during the enzyme reaction and the changes in the intensity are measured at a specific emission wave-length of the fluorescent group employed.  The rate of change of the invensity is proportional to the enzyme activity in the sample.  The invention concerns also the new compounds containing fluorescent groups to be used in the method.

Abstract: ABSTRACT OF THE DISCLOSURE An automatic speed control for a heavy duty vehicle includes a controller which regulates communication between a compressed air source and an air actuated throttle mechanism.  The controller generates a control signal which is a function of a speed error signal and the position of the air actuated throttle to regulate the compressed air source.  The speed error signal is calculated as the difference between a commanded speed signal and an actual speed signal.  To generate the control signal, the error signal and throttle position signal are operated on by different lead-lag transfer functions.  These lead-lag terms are thereafter combined with a proportional speed error term to yield the desired control signal.  The system further includes a throttle control feature for powering auxiliary equipment when the actual speed signal is zero.  Another feature of the control limits the commanded speed signal to a set value when it exceeds a predeter-mined limit.
