Abstract: ABSTRACT            A fractional part of a voltage to be regulated is applied between the base electrodes of first and second emitter-coupled transistors having base-emitter junctions with different VBE versus current characteristics.  The collector currents of the first and the second transistors are caused to be in a predetermined ratio by a degenerative feedback loop which adjusts the value of the voltage to be regulated.  Since the aforesaid fractional part of this voltage must vary linearly with the temperature change of the first and second transistors in order to maintain their collector currents equal, the voltage to be regulated must vary inversely as this fraction with that temperature change.  The fractional part can be of fixed value, in which case the voltage to be regulated will vary linearly with the temperature change of the first and second transistors, or it can be changed from one value to another to cause the voltage to be regulated to vary in a more complex manner with temperature.

Abstract: --Abstract of the Disclosure -  Sterically-hindered triorganotin compounds of the general formula               or          effectively combat fungi and mites when applied to objects, particularly plants, that are susceptible to attack by these organisms.  The present compounds are particularly advantageous in that they are considerably less phytotoxic than homologous triorganotin compounds wherein the hydrocarbon radicals contain between 4 and 6 carbon atoms (e.g. n-butyl and n-hexyl radicals).  In the foregoing formulae X is selected from the group consisting of a chlorine, bromine, fluorine, hydroxyl, cyanide, carbamate, thiocarbamate, amide (NH2), amino (NR? or NR1H),nitrate, enolate, carboxylate   phenoxy, alkoxy (-OR1) and mercaptide (-SR1) radical wherein R1 represents an alkyl radical containing between 1 and 12 carbon atoms or an aryl radical containing between 5 and 10 carbon atoms, inclusive, Y is an oxygen, sulfur, or a sulfate radical and n is an integer between 0 and 4, inclusive.

Abstract: ABSTRACT A slimming lotion serves without chemical reaction or muscular activity to obtain by simple local application a controlled cooling lasting for a long time in order to accelerate cellular vibrations by activation of the circulation of the blood so that the fatty cells, because of the intensity of this reactionary circulation, draw more oxygen from the arterial capillary blood vessels, thus more carbon dioxide gas to the venous capillary blood vessels, thus causing their elimination.  A process for preparation of the lotion comprises the mixing of ethyl alcohol, distilled water, crystallised camphor, menthol Codex Registered Trade Mark, potassium iodide, sodium chloride, calcium chloride, and perfume essence.

Abstract: (D-75) The disclosed voltage regulator circuit provides a regu-lated direct output voltage, across first and second output termin-als, when an unregulated direct input voltage is applied across first and second input terminals.  The second terminals are common to both input and output connections.  A voltage reference device, having first and second electrodes, is connected so that the second electr-ode is connected to the second terminals.  A first DC amplifier has an input circuit connected between the first input terminals and the first electrode, and an output circuit connected between the first output terminals and the first electrode.  A second DC amplifier has an input circuit connected to the input circuit of the first DC amplifier and an output circuit connected to the output circuit of the first DC amplifier.  The second DC amplifier, besides -sharing the current load requirements with the first DC amplifier, also controls a bias current through the voltage reference device.  The voltage reference device provides both amplifiers with a constant reference voltage enabling the amplifiers to maintain a constant output voltage despite changes in input voltage.

Abstract: FAIL SAFE DIGITAL CODE RATE GENERATOR              ABSTRACT OF THE DISCLOSURE       A digital code rate generator comprises a digital number generator driven by a clock running at an appropri-ate frequency.  Preferably the digital number generator is arranged to simultaneously generate digital representations for a plurality of different numbers.  These different digital representations are provided to a selector which passes one of said digital representations to an accumu-lator.  The accumulator continually sums the digital re-presentations provided to it by the selector.  An output of the accumulator is connected to an overflow detector which is distinctively operated when the sum of the digital representations provided to the accumulator exceeds the capacity of the accumulator.  By selecting the frequency of the clock and the particular digital representation which passes the selector, the rate of operation of the overflow detector can be controlled.  The output of the overflow detector thus comprises any one of a number of selectable digitally generated code rates.
