Abstract: TOGGLE MECHANISM CONNECTOR                        Abstract An over-the-center toggle mechanism for actuating locking dogs for connecting and disconnecting two underwater members.  The first member includes a locking notch and the second member slideably carries locking dogs for transverse movement for engagement and disengagement with the locking notch.  A toggle linkage includes a first pivot connection connected to the dogs and a second pivot connection longitu-dinally actuated by a piston whereby longitudinal movement of the second pivot connections transversely moves the locking dogs.  A resilient load spring acts against the second pivot connections and towards said first pivot connec-tions for locking the second pivot connections in a past dead center position relative to the first pivot connections.          The second member includes a tubular body having an annular cavity with a longitudinally reciprocal carriage mounted in the cavity and actuated by the piston.  The second pivot connections and the spring are transversely movable on the carriage and carried by the carriage.  Preferably the cavity includes seals for sealingly enclosing the cavity and in-cludes a flexible member exposed on one side to the interior of the cavity and on the second side to the exterior of the cavity for compensating for a difference in fluid pressure between the cavity and the outside of the body.

Abstract: ABSTRACT OF THE INVENTION          This invention provides a novel method for making polyether polyols from solid initiator compounds containing from 4 to 8 hydroxyl groups.  The method involves dissolving the solid initiator compound in a solvent such as dimethyl formamide prior to alkoxylation.  The method is particularly useful in making high functional sucrose-based polyether polyols which can be readily processed at moderate temperatures and give low color products.  These polyols are particularly suited for the production of rigid polyurethane foams.

And the fixed scroll member is so disposed in the cylindrical housing that the center of the cylindrical housing is offset from the center of the spiral element towards the terminal end of the spiral element thereof by R/2. In this arrangement, the inner radius of the cylindrical compressor housing is reduced to (a + 3R/2) at minimum.

Abstract: RADIO FREQUENCY ENERGY ANTENNA                      Abstract of the Disclosure A radio frequency energy antenna system for directing a collimated beam of radio frequency energy in free space over relatively wide scan angles.  The antenna system includes a plurality of antenna elements disposed along a curved path for producing a directed, noncollimated beam of radio frequency energy and a radio frequency lens disposed between the antenna elements and free space for collimating the radio frequency energy in the directed, noncollimated beam to produce the col-limated beam of radio frequency energy in free space.  The arrangement of the antenna elements along a curved path produces an amplitude distribution across the collimated beam wavefront which is substantially uniform.  A second radio frequency lens has a plurality of array ports coupled to the plurality of antenna elements and a plurality of feed ports, each one being associated with a corresponding collimated beam of radio frequency energy in free space.  With such lens the antenna has a relatively wide operating bandwidth.  The disposition of the antenna elements along the curved path enables the second lens to be smaller in size and have a shape wherein the array ports and feed ports face one another to a greater degree than if the antenna elements were disposed along a straight line thereby improving the operating effectiveness of the second lens.

Abstract: ABSTRACT     A gas flow unit such as a vaporiser mountable on a gas administration apparatus such as an anaesthesia machine in plug-in fashion includes an interlock system which prevents a valve for controlling the admission to the unit of gas from a supply provided by the apparatus from being operated before a locking mechanism has locked the unit to the anaesthesia machine. The interlock system also includes actuating means which, when the unit is mounted on the anaesthesia machine, opens respective valve members in ports located on the anaestheia machine only when the control valve is moved to its operating position.    In the case when two similar units are mounted side-by-side on the anaesthesia machine and intended for use as alternatives, the interlock system includes pins which when the control valve on one unit is moved to its operating position, extend outwardly from the unit to prevent the control valve on the other unit from being operated.

Abstract: RCA 73,432 Abstract of the Disclosure In a color television receiver including a comb filter for separating luminance and chrominance components of a color television signal, a network is included for enhancing vertical image detail to enhance vertical resolution in the luminance content of a displayed image. The comb filter provides a combed luminance signal output from which vertical detail signal information has been unavoidably deleted, and a combed chrominance signal output including signal frequency components representative of the deleted detail signal, which are selectively extracted from the combed chrominance signal.  Low level detail signals are restored to the combed luminance signal via a first signal processing network which exhibits a prescribed signal restoration gain.  The detail signal is also added to the combed luminance signal via a second network which cores (removes) low level detail signals including noise in a first operating mode, and amplifies higher level detail signals to enhance vertical image definition in a second mode.  Rapid transitions from the coring to the enhancement mode are undesirably manifested in a displayed diagonal image as serrations along the edge of the diagonal line. The visible effects of the serrations are reduced to an acceptable minimum by low pass filtering the enhanced cored detail signal before being added to the combed luminance signal.

Abstract: D-? ?B JEF:eo A METHOD AND APPARATUS FOR REMOVING NOISE      IN A LORAN-C NAVIGATION RECEIVER     Abstract Noise generated in the front end of a LORAN-C receiver that causes noise bias interfering with carrier cycle detection is effectively removed by periodically shifting the phase of all received signals by 180° in the front end of the receiver and then removing any phase shift elsewhere in the receiver where noise is no longer a problem but before the phase shift can affect time difference of signal arrival measurements normally made in LORAN-C receivers.  In this manner, noise generated in the front end of the receiver is averaged out and doesn't introduce bias levels to the received signal.
