Patent EP-0395561-A2 (EP)
Inventor: BRUNER DAVID ALLEN
IPC: H01H13/30
Filed: 1990-03-27
Abstract: A switch activator is described which is a unitary molded plastic molded coil spring (22) and a pivot plate (16) which pivots to act on a membrane switch (18) when the coil spring buckles under load. The buckling of the spring is controlled by the relative placement of the axis of the spring and a pivot surface around which the top portion of the spring pivots as the spring buckles. The cross section of the spring member is limited in size so as to prevent the forming of a solid column upon compression, while at the same time accommodating the needs for molten plastic flow in the spring during molding.

Abstract: 2.1 In compressed-gas-insulated switching devices, bushings are inserted in a gastight manner into the housing walls of said devices. In order to be able to carry out cable tests of the cables which are connected to the bushings, special measures are necessary in order to be able to carry out measurements on the relevant cables while adhering to the safety regulations. For this purpose, it is known for separate bushings to be used in addition to the cable bushings, which bushings are externally connected in a three-phase manner to an earthing rail and, by means of contacts which are placed in the internal space of the device, represent a part of the inner earthing switch. Using this construction, the outer earthing rail can be removed, and the internally located switch can switch (internally) into the contacts placed there, it being possible to carry out a cable test in this switching state. The removal of the external earth connection results in a safety problem. 2.2 The invention indicates a means by which a cable bushing with a test connection can be simplified and, at the same time, safety can be improved. To this end, an apparatus connecting part (1) is provided between an attachment flange (2) and a conical section (3) with a section (4) which has a lateral opening (6) which extends as far as the live inner conductor (5), it being possible to insert into this opening an adaptor (7) whose inner conductor (8) can be electrically connected to the live inner conductor (5) of the apparatus connecting part (1). 2.3 Such a bushing with a cable test connection can preferably be used for compressed-gas-insulated switching devices. <IMAGE>

Abstract: Disclosed is a processing apparatus capable of optimizing its rule base comprising a plurality of rules having an antecedent and a consequent each. The antecedent contains input conditions of machining, and the consequent describes the result of machining. The antecedents are applied to input condition data. The consequents of the applied rules yield machining result data that are evaluated for rule fitness. When the rule base is updated, some rules are deleted and some preserved depending on their degrees of fitness. Between given two rules having the same consequent, any number of corresponding conditional elements in their antecedents are exchanged so as to generate new rules. The process is repeated until the rule base is optimized. With the antecedents of rules applied to input condition data and with the consequents of the applied rules yielding machining result data, those data may be modified according to modification request data. The consequents of rules are applied to the modified machining data, and the antecedents of these applied rules furnish corrective input condition data. This backward application of rules is an easy way to obtain corrective input condition data.

Abstract: s7 A semiconductor memory device is provided wherein first data is read out from a first memory cell (101a) within a first readout period and second data is read out from the second memory cell within a second readout period. An amplifier circuit (107), receiving the first and second data, outputs first data signals (D) having a first electric potential level corresponding to the first and second data and a second data signal (D) having second electric potential level. A control circuit (120) generates, in response to an external control signal (RAS, CAS), a first control signal (LA2) in each of the first and second readout periods, the first control signal (LA2) indicating first logic level during an enabling period of time within each of the first and second readout periods, otherwise the first control signal (LA2) indicate second logic levels. A first latch circuit (129) latches the first data signal (D) in the respective first and second readout periods and outputs a first latched data signal (D1) at the time of the first control signal (LA2) indicating the first logic level. A second latch circuit (131) latches the second data signals (D) in the respective first and second readout periods and outputs a second latch data signal (D1) at the time first control signal (LA2) indicates the first logic level. A reset circuit places the first and second latch circuits (129, 131) in an initial state after the first control signal (LA2) changes from the first logic level to the second logic level in the first readout period and before the first control signal (LA2) changes from the second logic level to the first logic level in the second readout period.

Abstract: For transmission and reception of an ADPCM stream in which each of signal components is represented by a predetermined number of bits, an ADPCM transcoder comprises a bit number determining device (43) for producing a bit number signal representative of first and second bit numbers one at a time to make the ADPCM stream carry a voice component with the first bit number and a data component with the second bit number as two of the signal components. The first bit number is less than the second bit number. Preferably, a sum of the first and the second bit numbers is not greater than twice the predetermined number to make one of the two signal components comprise the voice component and a less significant part of the data component. The first and the second bit numbers are calculated from a voice and a data optimum scale factor which can be calculated by a method similar to adaptive prediction. The bit number signal need not be carried by the ADPCM stream. Alternatively, the transcoder may multiplex the bit number signal in the ADPCM stream for transmission and demultiplex the bit number signal from the ADPCM stream received to determine the first and the second bit numbers for use in an ADPCM decoder included therein.

Abstract: A loudspeaker system (100) having the ability to uniformly direct high-frequency as well as low-frequency sound hemispherically is described. The acoustical centers of a low-frequency driver (110) and a high-frequency driver (114) are aligned in space along axis (118) to provide a common source of sound to be directed through a common sound-guiding structure. The high-frequency sound is guided by the formation of an acoustical horn between the spherical mounting structure (102,112) of the low-frequency driver (110) and the reflector (108,116) generally employed in reflecting and diffracting low-frequency sounds. One side (108,116) of the acoustical horn has an acoustic path length smaller than the other (102,112), forcing sound to further diffract upon passage from the horn.
