Abstract: Abstract This invention relates to a very cost saving, practical and convenient method of providing the necessary grounding wire in the concealed low voltage 2-wire (one live phase, one neutral) electrical wiring system in buildings where such grounding wire was not taken into account during initial installation of the power supply.  Particularly, for this invention the owners of such buildings will not be, in near future, subjected to replace the previously installed 2-wire cables (without grounding wire) if such cables satisfy necessary insulation and other tests, by proper 3-wire grounding type cables; on the other hand this will enable them to achieve the same purpose by externally installing a suitable non-combustible single conductor grounding cable or cord, as the third wire of 3-wire system, from the supply ground terminal as located in the main circuit breaker and by terminating it to the existing outlet boxes namely electrical utility, junction or . . . . . . . . . . . . . . . . .     similar boxes through their respective modified cover plates For electrical safety reasons this will also encourage the owners of such buildings to have all previously installed 2-pin receptacle outlets replaced by 3-pin grounding type ones and to have the grounding pins bonded to system grounding wire. Lastly the manufacturers of all portable domestic appliances, tools, home entertainment and other equipment will have no objection in making their products with integral 3-pin grounding type male connectors along with proper detachable cord-sets where applicable, or with supply cords terminating, where applicable, in molded-on 3-pin grounding type male attachment-plug caps; this will not only make their products more reliable and safer but also will reduce their design, manufacturing and other associated costs in indirect ways. It will be a demonstrating effort and decision of the Government, affiliated authorities, electrical utilities, industries and the owners of old buildings to make this change-over.

Abstract: ABSTRACT OF THE DISCLOSURE         A heat-insulating body such as a heat-insulating slab is made whose insulating and heat-absorbing material includes a fine powder, in particular a silica aerogel which is pressed to form the body.  To carry out the pressing operation a sack-like sheath is required but between the sheath and the insulating material a separating agent is provided which results in the fact that the surface of the insulating material does not intimately engage with the sheath which is for example of glass fibre fabric, the sheath being movable with respect to the insulating material after the pressing operation.  Apart from the fact that the sheath can be removed for any cases where it would be a cause of disturbance, additionally the insulating body provides improved bending properties and even when made with a high pressing rate has a homogeneous structure.  To make the insulating body the separating agent may be applied to the inner surfaces of the sheath, the particulate insulating material then being introduced and the sheath sealed, whereafter pressure is applied.

Abstract: ABSTRACT      Strip form electrical terminals of the type to be engaged with complementary terminals by sliding movement during mating and unmating, each have a portion plated with contact metal extending over that part of Its surface which includes the contact zone and which extends beyond the contact zone in all directions.  The plated metal on the contact zone is of a thickness sufficient to withstand wear resulting from repeated mating and unmating cycles.  Portions of the plating which surround the contact zone are of a lesser thickness which is sufficient to prevent corrosion.  The extent of such s?ounding portions of the plating is s?fficient to prevent encroachment of corrosion products onto the contact zone by creep of such products produced at locations remote from the contact zone.  The terminals are electroplated by high speed strip plating methods and by following procedures, using a very thin linear anode, which produce the variable thickness plating in the plated areas of the terminals.

Abstract: Abstract of the Disclosure A pushbutton tunable radio having an integral audio graphic equalizer is disclosed.  During a tuning mode of operation for the radio actuation of any of five presettable pushbuttons results in the selection of a predetermined radio channel frequency within the AM or FM band, and a five digit display is provided indicating the selected channel frequency.  During an equalizer mode of operation caused by actuation an equalizer mode selecting pushbutton, the radio remains tuned to the previously selected radio channel, but the frequency indicating display is now replaced by an electronic display indicating the relative emphasis of a plurality of subbands for the corresponding audio signals produced in response to the received radio channel. In the equalizer mode, actuation of any of the presettable radio pushbuttons results in selecting a corresponding one of the audio subbands for adjustment of its relative emphasis.  The radio includes up and down manual pushbutton switches which provide for tuning the radio in discrete tuning increments in either upward or downward directions during the tuning mode of the radio.  During the equalizer mode, after one of the subbands has been selected by actuation of one of the presettable pushbuttons, actuation of the up or down tuning pushbuttons will cause a corresponding upward or downward discrete increment adjustment of the relative emphasis of the selected one of the audio subbands.

Abstract: ABSTRACT OF THE DISCLOSURE     A fill note generator for use in electronic musical instruments such as electronic organs which include a keyboard having a solo portion customarily played by the right hand and an accompaniment portion customarily played by the left hand.  A multiplexer scans the keys of the solo portion of the keyboard and generates a time division multiplexed solo data stream.          The keys of the accompaniment portion of the keyboard are interconnected so as to form twelve sets corresponding to the twelve pitches of the chromatic scale wherein the keys in each set are connected to a common output.          A multistage shift register has its load inputs connected to the outputs of the interconnected sets of accompaniment keys and produces on its output a fill note multiplexed data stream comprising keydown signals in time slots corresponding to the keydown signals loaded into its inputs from the outputs of the sets of accompaniment keys.          The inputs are recirculated in the shift register so that the pattern repeats itself once each octave of the scan of the solo portion of the keyboard.  A window circuit gates to an output the data stream on the output of the shift register for a predetermined number of time slots following the occurrence of the first occurring keydown signal in the solo data stream.

Abstract: HIGH VOLTAGE CONTROL OF AN ELECTROSTATIC PRECIPITATOR SYSTEM           ABSTRACT OF THE DISCLOSURE There is provided a precipitator system including a voltage controller which produces from an alternating power source a variable output.  This variable output drives a high voltage converter which applies a high voltage to a precipitator.  This variable output is controlled by a control signal from a command subsystem.  Preferably, the command subsystem is operative to repress the drive to the high voltage converter in response to its loading exceeding a predetermined limit during a corresponding limit interval.  After this limit interval, the command subsystem is operative to rapidly restore productive drive to the high voltage converter, preferably by the next half cycle of the power source that has a polarity opposite to that existing at the beginning of the limit interval.          In this fashion stabilized operation is quickly achieved.  Also included, preferably, is a conductive element that is coupled to the high voltage converter.  This conductive element conducts in response to variations in the extent to which the high voltage converter is being driven. The command system may store successive values of the voltage across the conductive element, using such values to adjust the control signal according to a predetermined relationship.  Such an arrangement can be used to adjust the control signal when a spark is imminent, thereby avoiding it.

Abstract: ABSTRACT OF THE DISCLOSURE        Pulses of accoustic energy are transmitted at normal incidence to the wall of a welded pipe, and also at an oblique angle thereto, wherein such transmissions, from respective transducers, occur immediately adjacent a girth weld.  Reflected pulses are then received and processed to analyze the radial extent of the girth weld at each inter-face between the pipe and the weld material.  By these means, undercuts or cracks in the weld are detected and analyzed as to their depth and profile.  The energy trans-mitted normal to the pipe wall determines the distance between the pipe and the pulse transducers, and a signal is then generated to simulate a reflection from the inner wall of the pipe with relation to an obliquely-directed pulse.  The transducers are then moved axially of the pipe and towards the weld, in small increments, in order to cause the oblique transmission of pulses finally to intercept the weld, thereby producing reflected pulse data when cracks or undercuts are encountered.  The heads are also moved circumferentially of the pipe in order to determine the circumferential extent of any undercut or crack.
