Abstract: Abstract of the Disclosure An automatically locking crossbolt deadlock.          Deadlock includes a vertically movable crossbolt which may be moved between locked and unlocked positions.  A lock button is movable between a first position in which the lock button positively holds crossbolt in its locked position and a second position in which crossbolt is free to move.  A drive lever is provided for moving crossbolt between its locked and unlocked positions.  Lock button is moved from its first to its second position upon rotation of a handle so that a panic exit may be accomplished without manually unlocking lock button.  In addition, lock button is movable to a third position for holding crossbolt in its unlocked position to provide an anti-lock out feature.

Abstract: ELONGATE ELECTRICAL CONNECTOR RETAINING DEVICE        Abstract of the Disclosure An electrical connector retaining device for retaining the male and female members of an elongate electrical cable connector in their mated positions is disclosed. The retaining device includes a semi-resilient strap and a rigid frame. The strap includes a planar region and one or more anchoring prongshaving bullet-shaped ends integrally formed with the planar region and projecting outwardly from one edge thereof. Extending obliquely outwardly from the edge of the planar region opposed to the prong edge is a flange. The flange is integrally formed with the planar region and includes a plurality of ridges that lie parallel to the edge from which the flange extends. The rigid frame may be integrally formed in the housing or chassis of an electrical subsystem, or as a separate item. The rigid frame includes an aperture in which one element (e.g., male or female) of the connector is mounted. That element is attached to the rigid frame.  Located in the rigid frame, along one of the longitudinal sides ofthe aperture are holes adapted to receive the anchoring prongs. On the opposite side of the aperture is a slot and one or more cross-bars adapted to receive andinteract with the ridges formed in the strap flange when the strap is wrapped over the assembled connector. The cross-bars may be located in an integral flange lying transverse to the plane of the portion of the rigid frame supporting the connector element. A multitude of cross bars form a ladder arrangement that interacts with a number of ridges, rather than a single ridge.

Abstract: ABSTRACT OF THE DISCLOSURE         A gas turbine engine fuel control for a main hydro-mechanical fuel flow control and an electrically operable valve in series with the flow control for speed limitation purposes.        The valve is controlled by a signal NL or NH derived from an engine speed transducer.  A phase advance compensation circuit advances the phase of the transducer signal and its output is applied to an error amplifier which compares it with a datum (which may vary with altitude).  The error signal is applied to a non-linear amplifier the amplification factor of which in-creases when a certain error threshold is  exceeded.  The com-bination of phase advance and non-linear amplification ensures rapid limitation of speed without introducing stability problems.

Abstract: ABSTRACT OF THE DISCLOSURE         A detecting transmitter device installed in opera-tive proximity with a surface to be observed includes an ultra-sonic waveguide installed in such surface.  Electronic equip-ment electrically connected to the ultrasonic waveguide trans-mits ultrasonic waves to the waveguide.  The ultrasonic waves proceed in the waveguide.  The equipment also receives the ultrasonic waves from the waveguide.  The degree of attenua-tion of the waves in the waveguide depend upon the difference in viscosity and other mechanical properties of water and ice, whereby the detecting transmitter device and the electronic equipment detect freezing of the surface by attenuation of the waves in the waveguide.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus are disclosed for forming a novel corrugated paperboard web of indefinite length, which web includes a planar facer layer and a corrugated layer the flutes of which extend longitudinally the length of the web.  The web is formed by splicing together sections having offset planar facer and corrugated layers of gener-ally equal dimensions, respectively whereby at one end the facer layer projects beyond the corrugated layer and at the other end the corrugated layer projects beyond the facer layer, the flutes of the corrugated layer extending from one projecting end to the other.  Successive sections are spliced together with the projecting facer layer portion of one section overlying the projecting corrugated portion and the facing layer of another section, preferably with the adjacent portions of the corrugated layers of the two sections being in flute-enmeshing engagement.  A conventional second web having a planar facer layer and a corrugated layer with transverse flutes may then be bonded in super-imposed relation to the first web, thereby defining a third web having successive corrugated layers the flutes of which extend longitudinally and transversely of the third web, respectively.

Abstract: ABSTRACT      A detachable balloon  catheter apparatus  and method. The apparatus includes an introducer catheter which is attached at its trailing end to a source of pressurized fluid.  The leading end of the catheter is attached  to  an  inflatable  balloon which may be inflated as the pressurized fluid is injected through the  introducer  catheter.   A valve mechanism is positioned inside the assembled introducer catheter and balloon and the leading end of the valve mechanism is bonded to the interior of the balloon.  As the balloon  is  inflated by the pressurized fluid,  a forwardly directed lateral force is exerted on the valve mechanism so that it is pulled forward into fluid-tight engagement with the valve seat placed at the opening of the balloon.  Once the valve mechanism is pulled into fluid-tight engagement so as to close off the opening of the balloon, further injection of the pressurized fluid serves to detach the inflated balloon from the introducer catheter.

Abstract: ABSTRACT         Electrical and mechanical synchronization of two or more synchronously driven gyroscopes, mounted on the same plat-form, to minimize cross-talk induced drift, is achieved by bringing one gyroscope to a speed which is slightly higher than the other by driving it at a slightly higher frequency.          At speed, coincidence of mechanical position is established by means of signals from pick-offs on each gyro and the drive for the faster gyroscope is shifted to the lower frequency.          Electrical synchronism is established by restarting the lower frequency generator to instantaneously establish a predeter-mined relationship between a pick-off signal and the frequency generator.  Phase-lock start-up of a single gyroscope by in-stantaneous shift of the phase of the driving voltage, relative to the gyroscope wheel position, is also provided.
