Abstract: ABSTRACT OF THE DISCLOSURE          A surgical staple remover comprises a first handle element and a second handle element pivotally connected to each other.  The front portion of the first handle element terminates in a pair of outwardly extending anvil sections having outside surfaces that diverge away from each other in the front to rear direction so that different size staples may be received thereon until the staples contact the diverging outside surfaces thereof.          A blade section on the front portion of the second handle element is constructed and arranged for movement toward and away from the anvil sections, and the blade section has a lower concavely curved staple engaging edge.  The curved edge engages a staple on the anvil sections with a downward and rearward force to produce a U-shaped bend in the crown of the staple to thereby facilitate its removal.  The surgical staple remover being simple and reliable to use and able to accommodate a wide variety of staple sizes.

Abstract: ABSTRACT IMPROVEMENTS IN OR RELATING TO LATCHING CIRCUITS A digital latching circuit (10) includes a quantizer having an input pair (11,12) of emitter-coupled transistors connected with output transimpedance circuits (15,25).  The quantizer is responsive to the state of an input signal (13) applied to the input pair for producing from the output transimpedance circuits a quantized output signal (30).  A feedback pair (31,32) of emitter-coupled transistors is interposed between the outputs of the transimpedance circuits and the inputs to the transimpedance circuits.  Current pulses (ICL, ?CL) are applied alternatively to the common emitter circuits of the input pair and the feedback pair of transistors for alternatively enabling the quantizing of the state of the input signal and the latching of that quantized state.

Abstract: ABSTRACT:           A polar loop transmitter in which a negative feedback bias adjusting system (76,78,80) is provided to control the bias voltage applied to a differential ampli-fier (30) which supplies the input envelope information to an amplitude modulator (36), so that the R.F. modulated output goes to zero for a zero in the input envelope information.  The negative feedback bias adjusting system (76,78,80) comprises a threshold circuit (76) for deriving a threshold voltage from the D.C. component in the output of the differential amplifier (30).  This enables negative going spikes to be separated from the output waveform and their amplitude used to control the D.C. correction com-ponent which is applied to an input of the differential amplifier.

Abstract: BOWED TURBINE BLADE             ABSTRACT OF THE DISCLOSURE        The invention comprises a blade for a gas turbine engine including an airfoil portion having a non-linear stacking axis which is effective for generating a compressive component of bending stress due to centrifugal force acting on the blade.  The compressive component of bending stress is provided in a life-limiting section of the blade, which, for example, includes trailing and leading edges of the blade.          Inasmuch as the stacking axis, which represents the locus of centers of gravity of transverse sections of an airfoil portion of the blade, is non-linear, an increased amount of a compressive component of bending stress can be generated at a life-limiting section between root and tip sections of the blade without substantially increasing bending stress at the root of the blade.

Abstract: A method and apparatus for contacting a flow of gas with a flow of liquid is provided. The liquid is introduced into a vortex sustaining container and flows through the container in a spiralling manner creating a liquid vortex with an open axial core. Gas flows to be contacted with the liquid flow are introduced into the core. The vortex core geometry may be adapted to accomodate insertion of a flame to effect heat transfer. The degree of contact between the gas and liquid flows may be increased by adding an extended contact zone following the region where the vortex flow breaks down and mixing of the liquid and gas flows occurs. By creating annular misting in the extended contact zone the rate of any chemical, physical or mass transfer process between the two flows may be increased.

Abstract: METHODS, AND APPARATUS, FOR TRANSMITTING HIGH-BIT-RATE         DIGITAL DATA IN POWER LINE COMMUNICATION         MEDIA HAVING HIGH HARMONIC NOISE CONTENT                 ABSTRACT OF THE DISCLOSURE         In a power line data communications system high bit-rate digital data is transmitted through a communications media, having high harmonic noise content, by use of a frequency-modulated chirp waveform.  The chirp waveform instantaneous frequency is at a predetermined center frequency at the start, midpoint and end of each bit time, interval, and makes substantially linear frequency changes to a maximum frequency and minimum frequency at selected ones of the one-quater and three-quarter bit-time-interval times.  A binary-one data bit is transmitted by increasing the instantaneous frequency to reach the maximum frequency at the one-quarter interval time, then decreasing the frequency to reach a minimum frequency at the three-quarter interval time, and reducing the instan-taneous frequency thereafter to reach the center frequency at the end of the bit time interval.  A binary-zero data bit is transmitted by initially decreasing the instan-taneous frequency to reach the minimum frequency at the one-quarter interval time, then increasing the instantaneous frequency to reach the maximum frequency at the three-quarter interval time, and reducing the instantaneous frequency thereafter to reach the center frequency at the end of the bit time interval.        One presently preferred embodiment of apparatus for transmitting the chirp frequency-modulation signal, and one presently preferred embodiment of apparatus for receiving the chirp frequency-modulated waveform for recovering the data modulated thereon, and associate timing information, are disclosed.

Abstract: Abstract of the disclosure:            Process for preparing highly concentrated aqueous press cakes of solids According to the invention, addition of one or more sur-factants having a cloud point in aqueous solution to an aqueous suspension of a solid gives after the isolation of the solid at a temperature above the cloud point aque-ous press cakes containing a large amount of this solid.          The direct processing of press cakes as obtained for example after the synthesis and isolation of dyes or pig-ments to give practical aqueous pastes or dispersions requires a minimum solids content in the press cakes.          The minimum content is frequently not obtained when conventional methods of isolation are used, so that it is necessary to proceed via the indirect route of drying to obtain the powders and redispersing the powders.  By using the process according to the invention it is possible to cut out the costly indirect route or, if desired, to reduce the expense of drying to obtain powders by an appreciable margin.
