Abstract: ABSTRACT OF THE DISCLOSURE Novel polyamides and polyalkenes modified therewith are provided herein.  The novel polyamides have an acid value below 15, preferably be-low 10, an amine number of 50-200, preferably of  75-150 (all in mg KOH/g) and are built up from groups derived from (A) an aliphatic diamine with 2-3 carbon atoms between the nitrogen atoms; (B) a triamine of the formula   in which R1 and R3 represent alkylene groups are R2 represents an alkyl group, which groups can contain 1 to 6 carbon atoms; (C) an aliphatic di-carboxylic acid containing 6 to 19 carbon atoms; and (D) a poly-merised fatty acid comprising up to 35, preferably 3-25 mol.% of the total di-carboxylic acids.  These novel polyamides make it possible to obtain excel-lent dyeing results with low percentages of additives being added, whereby, moreover, no neutralising step is necessary.  Adding low percentages of additives is important because this will as much as possible prevent the additive from affecting the properties of the polyalkene.  Thus, it has now been discovered that by modifying polyalkenes with certain novel polyamides, excellent dyeing properties, e.g., colour intensity, colour homogeneity and colour fastness can be obtained.

Abstract: ABSTRACT     A novel rapid chemical method of labeling plasma proteins, other compounds and/ or substances containing proteins with radionuclides of Technetium such as 95mTc, 99mTc or 99TC at physiologic pH 7.4 condition, producing a sterile non-pyrogenic ra-dioactive tracer material suitable for biological and medical uses. These radiola-beled protein substances are not denatured by the labeling process but retain their natural physiological and immunological properties. This novel labeling technique provides a simple and rapid means of labeling plasma proteins such as human serum albumin, fibrinogen, antibodies, hormones and enzymes with 95mTc or 99mTc for scin-tigraphic imaging which may allow visualization of thrombi, emboli, myocardial in-farcts, infectious lesions or tumors.

Abstract: A B S T R A C T           An improved optical system is disclosed for rapid, accurate spectral analysis of the reflectivity or transmissivity of samples.  A grating oscillated at high speed is utilized to provide a rapid scanning of monochromatic light through a spectrum of wavelengths.  The grating is positively driven at very high speed.  The rapid scan by the grating enables the reduction of noise error by averaging over a large number of cycles.  It also reduces the measurement time and thus prevents sample heating by exessive exposure to light energy.  Source optics is employed to project light radiation on the grating.  An exit slit receives light dispersed by the grating as the grating oscillates and a cylindrical lens in the path of light passing through the exit slit produces a virtual image of the width of the exit slit on the grating.  Optical means are provided to focus from the radiation passing through the cylindrical lens a real image of the composite of the virtual image of the width of the exit slit at the grating and the height of the grating and to project the radiation the sample.  Photosensing means are provided for detecting radiation from the sample.

Abstract: ABSTRACT OF THE DISCLOSURE            The system serves to control the heating of dispensable water, which is to be stored in a storage tank (1). A heat exchanger (9), which is separate from the storage tank, is connected in primary and secondary fluid circuits. The water to be heated is taken from the bottom of the storage tank (1) and is handled by a thermostat-controlled charging pump (10) to flow in the secondary fluid circuit through the heat exchanger (9) and to return as hot water to the top of the storage tank. The control system comprises a first thermostat (T1), which extends into the stor-age tank (1) preferably in the middle  portion of its height, and a second thermostat (T2), which extends into the secondary fluid circuit between the cold water zone at the bottom of the storage tank (1) and the point where the secondary fluid circuit enters the heat exchanger (9), The first thermostat (T1) serves to start the charging pump (10) to initiate the charging operat-ion. The second thermostat (T2) serves to de-energize the charging pump to terminate the charging operation. The first thermostat (T1) closes an electric circuit when sensing a water temperature below a predetermined lower limit. The second thermostat opens an electric circuit when sensing a water temperature above a predetermined upper limit.

Abstract: ABSTRACT    A pressurized can (3) containing material to be dispensed by evaporation is inserted into a case (1) and se-cured therein by latches (16). An actuator assembly comprises an annular solenoid (21,22) surrounding a plunger (28). The plunger (28) has an axial bore for receiving a shaft tube (29) which is pressed by plunger (28) on a can valve when the solenoid (21,22) is energized. The shaft tube (29) is provided with a nozzle tube (31) extending toward the open-ing (37) of an annular electrical heating device (34) com-prising a perforated disk (39). Material from the can (3) is released by energizing the solenoid (21,22) automatically at selectable time intervals for preset durations. The ma-terial falls on the heated perforated disk (39) and evapor-ates through the holes (40) in the disk (39) into the atmosphere.

Abstract: Abstract A two-pole monolithic crystal filter is described that includes grounded strip electrodes between input and output electrodes.  The grounded strip electrodes have a higher resonating frequency than the input and output electrodes and also provide increased acoustical coupling and lower inter-electrode capacitance between the input and output electrodes, while having little or no effect on the midband electrical characteristics of the filter.  Because of the increased coupling, the input and output electrodes can be spaced further apart than heretofore possible in prior mono-lithic crystal filters.  Moreover, further increases in the acoustical coupling can be achieved by arranging a plurality of strip electrodes between the input and output electrodes. The inventive monolithic crystal filter can be advantageous-ly utilized for filtering the IF signal developed in the IF portion of an FM radio receiver.
