Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed, in combination, a window frame including inter-connected pairs of opposite, spaced parallel, frame members defining a sash receiving opening; a sash mounted in the opening for pivotal movement about a sash pivot axis extended transversely between opposite members of one of the pairs of the frame members between a closed, open and a reverse position relative to the frame, and a releasable latch assembly positioned apart from the axis between the axis and a frame member parallel thereto at an adjustably selected spacing therebetween.  The latch assembly interconnects one of the frame members transverse to the pivot axis and the sash for limiting the amount of initial pivotal opening movement of the sash out of the closed position into a limited open position.  It includes key releasable means oper-able for permitting further pivotal movement of the sash out of the limited open position through a freely pivotal open position toward the reverse position.  The latch assembly includes a key operated latch movable between a latching and a releasing position for permitting the free opening movement of the sash, and means for retaining the key in the latch whenever the latch is intermediate the latching and releasing positions.

Abstract: Phthalocyanine dyes containing an ortho-amino-sulfanilide group, and process for preparing them Abstract of the disclosure:      Very valuable, new phthalocyanine compounds, suitable as dyestuffs, had been found which contain one or several ortho-amino-sulfanilide groups.  These dyestuffs can be applied and fixed on various fiber-materials, especially in accordance with the old ice-color technique. The novel dyestuffs are fixed by treating them on the material on which they had been applied, by means of nitrous acid.  The dyeings and prints thus obtained possess very good fastness properties, such as to rubbing, to washing and to light.

Abstract: ABSTRACT OF THE DISCLOSURE         A combination heat storage material capable of functioning in two discrete temperature regimes, and comprises of two constitutents, one of which has a phase change in the temperature range of between about 35°F. and about 55°F., and the other of which has a phase change in the temperature range of between about 90°F. and about 130°F.  The two constituents are essentially non-reactive with each other and thereby maintain their independent phase change characteristics.  They can therefore function in a heat pump environment to provide a heat sink, into which heat may be dissipated for air-cooling purposes, as well as a heat source which provides heat for heating purposes.

Abstract: ABSTRACT OF THE DISCLOSURE           The variable speed transmission includes a power input drive shaft and a variable throw crank having a zero throw position aligned with the input shaft.  The variable throw crank is coupled to the input shaft for rotation there-with and its eccentricity with respect to the axis of rotation of the input shaft can be varied.  A control plate, also referred to as a master link, is rotatably mounted on the crank and a plurality of clutches having input and output shafts are operatively connected to the control plate through a plurality of pitman type links, whereby the control plate oscillates the input shafts of the clutches upon rotation of the power input shaft and variable throw crank of the trans-mission.  The outputs of the clutches are connected to an out put shaft for the transmission.  By varying the throw of the ...        . variable throw crank the ratio between the rotary speed of the output shaft can be infinitely adjusted from zero to a maximum ratio determined by the maximum eccentricity of the variable throw crank with respect to the axis of rotation of the input shaft.  A preferred embodiment is to revert the above.

Title: Method for operating a nuclear reactor to accommodate  load follow while maintaining a substantially constant axial power distribution

Abstract: 46,676 AN IMPROVED METHOD FOR OPERATING A NUCLEAR  REACTOR TO ACCOMMODATE LOAD FOLLOW WHILE MAINTAINING A SUBSTANTIALLY CONSTANT AXIAL POWER               DISTRIBUTION     ABSTRACT OF THE DISCLOSURE         This invention provides a method of operating a nuclear reactor having a negative reactivity moderator temperature coefficient with the object of maintaining a uniform and symmetric Xenon distribution above and below substantially the center of the core over a substantial axial length of the core during normal reactor operation including load follow.  In one embodiment variations in the Xenon distribution are controlled by maintaining a substan-tially symmetric axial power distribution.  The axial offset, which is employed as an indication of the axial power dis-tribution, is maintained substantially equal to a target value, which is modified periodically to account for core burnup.  A neutron absorbing element within the core coolant, or moderator, is employed to assist control of reactivity changes associated with changes in power, with the full-length control rods mainly employed to adjust variations in the axial power distribution while the part-length rods remain completely withdrawn from the fuel region of the core.  Rapid changes in reactivity are implemented, to accommodate corresponding changes in load, by a controlled reduction of the core coolant temperature.  Thus, active core coolant temperature control is employed to control the reactivity of the core during load follow operation and effectively increase the spinning reserve capability of a power plant without altering the axial power distribution.

Abstract: Abstract Of The Disclosure A hybrid bridge circuit has a feed amplifier and an aux-iliary resistor connected in series with the output of the re-ceive amplifier between the amplifier and a node of the bridge so that signals from the receive amplifier are transmitted through the two-wire line port in the bridge to the auxiliary resistor and a resistive leg of the bridge, and signals from the two-wire line port and the adjacent resistive leg of the bridge and the node V2 between the compensating network in the bridge and the adjacent resistive leg of the bridge.  a differential transmit amplifier differentially receives inputs from the nodes V1 and V2 so that the differential amplifier produces a partially equalized output signal corresponding to the difference between the voltages at the nodes V1 and V2.  The resistance values R1 and R2 of the two resistors legs of the bridge, and impedances ZC and ZL of the compensating network and the two-wire line in the bridge, satisfy the equation   to maximize the transhybrid loss, and the resistor R2 adjacent the compensating network is sub-stantially larger than the resistor R1 adjacent the two-wire line to minimize the power losses in the compensating network and the resistor R2.  This hybrid bridge circuit can be used in repeaters or terminating devices in communication networks.
