Abstract: ABSTRACT         Thiocarbamyl derivatives, including thioureas and thiocarbamic esters derived from the reaction of an alkenyl isothiocyanate with an amine and alcohol or thiol, respec-tively, have utility as an additive for hydrocarbons, parti-cularly fuels and mineral lubricating oils, whereby enhanced anticorrosion, oxidation inhibition and/or dispersancy acti-vity is imparted to said hydrocarbons.  The derivatives can be made by the formation of an adduct of thiocyanogen halide and polyalkene, removal of the hydrogen halide from said adduct and thermal rearrangement of the product to provide a polyalkenyl isothiocyanate which can be subsequently de-rivatized to provide a thiocarbamyl moiety containing pro-duct having sludge dispersing properties.

Abstract: D-22,366 CARRIER FREQUENCY SPECTRUM GENERATOR     USING LOGIC LEVEL INPUT PULSES     by Lawrence E. Getgen ABSTRACT OF THE DISCLOSURE     An inverter accepts the true form of a high-frequency signal at its input and provides the complement thereof at its output.  The true form is applied to a first input of a first NAND-gate and the complementary form is applied to a first input of a second NAND-gate.  A second signal, having a repetition rate which is set, for example, by the channel spacing required in an FDM carrier system, is applied to the second inputs of said first and second NAND-gates.  The second signal is thereby alternately switched between the first and second output terminals of said NAND-gates at a rate equal to the frequency of the high-frequency signal.  The first and second output terminals of said NAND-gates are connected to the first and second end terminals, respectively, of the primary winding of an output transformer.  The end terminals of the secondary winding of said transformer are connected to the load or utilization device.  The output signal comprises a spectrum having a sin x/x envelope centered at the high-frequency wc.  Spectral rays occur at the high-frequency wc and are disposed on either side of wc at intervals equal in frequency to the pulse rate of said second signal.

Abstract: RCA 74,648 ABSTRACT           An integratable third harmonic signal generator comprises an amplitude limiting amplifier (30), a linear amplifier (20), and a signal combining network (40).  A sinusoidal input signal is coupled to the limiter and linear amplifiers.  The limiting amplifier generates a square wave signal containing a first harmonic (fundamental) component at the frequency of the input signal, and higher order odd harmonics including a desired third harmonic frequency. The signal gain of the linear amplifier is set so that the magnitude of the output signal from the linear amplifier is sufficient to cancel with the first harmonic of the square wave output signal from the limiter amplifier, when these output signals are combined in the combining network. A resulting signal developed at the output of the combining network contains the desired third harmonic component, as well as higher order harmonics at acceptably reduced levels relatve to the third harmonic component, to the substantial exclusion of the first harmonic component.

Abstract: ABSTRACT OF THE DISCLOSURE          A novel meter is provided for measuring erythrocyte settling rates.  It includes a base supporting a rack adapted to hold an array of tubes at an optimum settling angle, and at least one tube for such rack, the tube being adapted to contain blood samples, the tube including a window of predetermined length at the upper end thereof, the window being of sufficient length to permit the passage of ambient light there-through.  A timer is provided, which is actuated by the passage of light through the window when the tube contains blood, to determine the erythrocyte settling rate.  This timing is achieved by signalling that a preset period of time has elapsed between when a minimum amount of light passes through the window, indicative of the presence of erythrocytes in the area of the window, and when a maximum amount of light passes through the window, indicative of the substantial absence of erythrocytes in the area of the window.  By this invention, a blood test may be done in 5 to 15 minutes.  A doctor (or probably his nurse) can perform the test while continuing the examination of the patient and have the results in time for diagnosis.
