Abstract: ABSTRACT: "Picture display device for displaying a binary signal generated by a picture signal generator as a binary inter-laced television picture".        In an interlaced picture display device by means of which signal patterns are displayed which are uniform from field to field as obtained from character generators vertical jitter and flicker phenomena are greatly reduced by attenuating the uppermost picture element of a sequence of subjacent bright picture elements in one field in com-bination with attenuation of the bottommost picture element in the other field or in combination with the addition of an attenuated picture element of the bottommost picture element of one field.

Abstract: ABSTRACT OF THE DISCLOSURE           Caffeine is extracted from the raw coffee by means of an aqueous liquid and adsorbed from the latter on an adsorption agent such as activated charcoal.  In order for the adsorption agent to absorb as little as possible of other substances that are extractable from the coffee, the agent is previously loaded with such other extractable substances or with substitute substances having a molec-ular structure and size similar to the latter, more partic-ularly with carbohydrates as exemplified by cane sugar.  The aqueous extractant is preferably a caffeine-free coffee extract solution which substantially extracts only caffeine from the coffee.  Other aqueous liquids may be employed, but generally require recombination with the coffee after the adsorption step.

Abstract: ABSTRACT OF THE DISCLOSURE Gaseous hydrogen chloride is extracted from dilute aqueous hydro-chloric acid using amines, by extracting the aqueous hydrochloric acid with an amine or with a mixture of an amine and an inert, water-immiscible solvent having a boiling point of at least 120°C.  The amine is a tertiary alkyl-amine containing 14 to 36 carbon atoms in the nitrogen-bound side chains, the side chains having at most one nitrogen-bound metbyl group and at least one nitrogen-bound aliphatic group containine at least 6 carbon atoms, the amine acid constant being less than 10-3.  An inert, water-immiscible solvent having a boiling point of at least 120°C is then added to the extract, unless the solvent was already added in the first stage.  The extract is distilled, the vapors generated are condensed and water is continuously separated from the two-phase condensate and the organic phase fed back into the distilla-tion procedure.  An aminohydrochloride cleavage step is carried out by dis-tilling the extract at reflux after removing the water and evacuating the gaseous hydrogen chloride released at the head of the column or by separat-ing the hydrogen chloride from the extract after removing the water at less than the boiling point of the solvent by passing an inert gas flow there-through.  The solvent containing the amine is fed back into the extracting procedure and carboxylic acid chloride is added at least in stoichiometric quantity referred to the primary and secondary amines formed from thermal dissociation of the alkylamines, solvent and any impurities.

Abstract: SKIN PREPARATION DEVICE AND METHOD FOR THE APPLICATION OF MEDICAL ELECTRODES                          Abstract A method and device are disclosed for preparing the skin of a patient to ensure good electrical contact between a medical monitoring electrode and the plaintiff's skin relative to a reference electrode secured to an already prepared site on the skin of the patient. The electrode includes an abrasive pad impregnated with an electrolyte for providing good electrical contact with the patient's skin. When a monitoring electrode is used, the abrasive pad is secured to the skin and is rotatably driven by a preparation device which continuously measures the impedance between the pad of the electrode and a reference electrode secured to a prepared site on the skin.  Rotation of the pad of the electrode terminates within a predetermined period or when the impedance between the pad and reference electrode falls to a predetermined value, whichever occurs first.

Abstract: RCA 73,113 Abstract of the Disclosure A circuit for generating a composite keying signal comprises a burst gate circuit and a voltage trans-lating network in a color television receiver also including keyed signal processing circuits and means for deriving horizontal and vertical blanking signals and a horizontal sync signal from a composite color television signal containing a color burst component.  The burst gate circuit responds to the horizontal sync signal to develop a burst gate pulse encompassing the burst interval.  A voltage level developed by the translating network in response to the horizontal and vertical blanking signals is combined with the burst gate pulse to produce a com-posite keying signal.  The composite keying signal comprises a first pulse component of a desired level as determined by the translating network and occurring during the blanking intervals, and a second pulse component as provided from the burst gate circuit, superimposed on the first pulse and encompassing the burst interval.  Means are also included for inhibiting the output of the keying signal generator during picture intervals of the tele-vision signal, to prevent false keying of the keyed circuits in response to keying signals generated by the keying signal generator in the presence of spurious input signals occurring during picture intervals.

Abstract: Abstract:        Process and appliance  for the production of aqueous solutions of sodium chloride from rock salt The invention relates to an open dissolving chamber for rock salt and to a process for the produc-tion, free from vapors, of concentrated, aqueous sodium chloride crude brine by continuously dissolving rock salt in this dissolving chamber,    The dissolving chamber contains a heap of rock salt with which the brine which is unsaturated in respect of salt comes into contact, The brine thereby becomes saturated with sodium chloride and then passes cut of the dissolving chamber.    In the present process, the unsaturated brine enters at the base of the dissolving chamber.    The saturated crude brine is removed from the rock salt through at least one vertical or inclined screen which largely holds back suspended rook salt particles.    The liquid level of the saturated crude brine in the dissolving chamber should not reach the surface of the heap of rock salt, and the side of the screen facing the interior of the dissolving chamber should be completely covered with a mixture of saturated crude brine and rock salt.

Abstract: 48,914 ABSTRACT OF THE DISCLOSURE A lighting apparatus which provides  for high-voltage pulses  for starting a high-pressure sodium dis-charge lamp and thereafter provides operating ballasting. The apparatus uses two capacitors and associated blocking diodes and a charging resistor.   One of the capacitors charges toward the peak of the line voltage in the nega-tive half cycle,  and thereafter, when the line voltage goes positive, the voltage on the one capacitor is added to  the  line voltage  for charging  the other capacitor. When the voltage on the other capacitor reaches a pre-determined voltage exceeding the Zener voltage of a paral-leling Zener diode which Zener voltage may be about twice the peak voltage of the line,  the other capacitor dis-charges through a ballast inductor which is connected in autotransformer relationship therewith to provide a high voltage pulse of sufficient magnitude to start the lamp.
