Abstract: From the new exchange (NV), the subscriber lines are successively selected, the subscriber lines being simultaneously connected to the new exchange (NV) and to the old exchange (AV) via the main distribution frame (HV), and connections are established from a test access (T) to these subscriber lines through the old exchange. Via these connections, the audio frequency generator of the new exchange supplies a test code word which passes via a line-individual test connection contact (x) and an external test bus (EB) to the code signal receiver (CR) of the new exchange and is checked there for correspondence with the test code word.

Abstract: A process for producing non-corrosive double-wall tubing in which an unbrazed, unsealed continuous double-wall tube of a given circumference is formed from a metal sheet composed of a first non-ferritic metal having a first defined region of exposed non-ferritic metal and a second region of a second metal in overlying relationship thereto, said exposed region having a width essentially equal to the circumference of the finished tube. The process including the steps of elevating the surface of the stainless steel to a brazing temperature while maintaining the material in a humidified gaseous atmosphere consisting essentially of a non-reactive carrier gas and a reactive gas present in sufficient concentrations to achieve fluxing; maintaining the surface temperature of the steel for an interval sufficient to permit fusion between the selected metal and the non-ferritic steel surface; after metal fusion has been achieved, allowing the resulting fused metal material to cool to a first lowered temperature in a controlled non-oxidative atmosphere at a rate which retards the formation of fine-grained steel crystals in the metal; and after reaching a metallurgical transformation point, rapidly cooling the fused metal in a controlled atmosphere to a temperature below which the brazing metal is not reactive with oxygen. 
     This process can be employed successfully in manufacturing unique, double-wall tubing which is relatively flexible and highly corrosion resistant.

Abstract: A method and process for reducing the frequency lock-on time required for a radiotelephone transitioning from a standby mode to a normal operation mode. The present invention comprises a microphone (101) coupled to a transmit synthesizer (104) through audio circuitry (102), a reference oscillator (103), and a transistor switch (109) controlled by a processing device (110). The transmit synthesizer (104) is comprised of a phase detector (105) coupled to a loop filter (106) that is coupled to a voltage controlled oscillator (VCO) (107). The output of the VCO (107), which is also the output of the present invention, is fed back through a divide by N (108) to the phase detector. The microcomputer (110), in the standby mode, periodically switches on power to the transmit synthesizer (104), keeping a capacitor in the loop filter (106) charged and thereby maintaining the voltage applied to the VCO (107). This voltage determines the frequency of the signal produced by the VCO (107). If this voltage is kept at the level used during normal operation, when the radiotelephone goes from standby to normal, this voltage will be close to the proper level.

Abstract: A level conversion circuit includes an ECL logic circuit (1) including a current switch circuit having first and second transistors (T1,T2), each of the transistors having an emitter coupled to each other and at least one thereof receiving an input signal (IN,XIN) of ECL logic level, and an output transistor (T3,T4) coupled to a collector of at least one of the first and second transistors; a current control circuit (3) including a current mirror circuit having third and fourth transistors (T5,T6), at least one of the transistors being coupled to an output end of the output transistor, and controlling a current flowing through the output end to thereby carry out a level conversion of a signal at the output end; and a switch circuit (2) operatively coupled to the current control circuit. The switch circuit responds to a control signal (C) and thus controls a supply of a current or a break thereof from the output transistor to the current control circuit. As a result, it is possible to decrease a power dissipation in the present level conversion circuit without spoiling a high speed operation thereof in a stand-by state of an apparatus or system to which it is applied.

Abstract: A clock circuit (12) normally couples clock pulses to a microprocessor (11), which is capable of accessing memory devices (13,14) having different access times. Access of a "slow" memory device 14 is detected by the clock circuit, and in response thereto, one or more clock pulses are not coupled to the microprocessor. This suspends operation of the microprocessor for a suitable amount of time so that the microprocessor reads valid data from the slow memory device. The number of clock pulses blocked from reaching the microprocessor can be set in a delay circuit in the clock circuit.

Abstract: To increase, in an installation unit (10) having an outer frame (11) which is supported on a carrying framework (12) fixed to the bare floor, the static strength of the outer frame (11), a thin-walled metal plate (19), preferably a galvanised steel sheet, is fixed to the outer frame in grooves (26) as a covering element, which is constructed at the same time as a plaster or tile base and for this purpose is provided with slotted bridge holes (23). The marginal bridge portions (25) of the slotted bridge holes (23) engage partly or totally into the grooves (26) in the outer frame (11). As a result, they form, by way of their respective engagement length, clamping portions (25a) in the grooves (26) which, on pushing the metal plate (19) into the grooves (26) of the outer frame (11), are correspondingly deformed. These clamping portions strengthen the clamped connection between the metal plate (19) and the outer frame (11). In addition, the metal plate (19) having the slotted bridge holes (23) reduces to a large extent the escape or the trickling-out of the sound-insulating material, situated inside the outer frame (11), to the outside. <IMAGE>

Abstract: Polymer compositions having a first and second portion selected from polypropylenes, polyethylenes, propylene-ethylene copolymers and mixtures thereof having enhanced crystallization properties and a method for producing the same are disclosed. Antioxidant is mixed with the first portion, 0.01 to 1.25 wt %, of the composition which is then irradiated to a dosage of 5-30 Mrads of ionizing radiation in air to induce cross linking. The irradiated first portion is then blended with the non-irradiated second portion. The cross-linked polymer is believed to provide nucleation sites for the initiation of crystallization, thereby enhancing crystallization of the polymer as evidenced by elevated DSC freeze points. Crystallization of the polyolefin is enhanced without any detrimental effects on hexane or xylene extractability of the polymer and without degrading the composition to any appreciable extent.

Abstract: Apparatus for transmitting signals for an EDTV system for reception on standard NTSC television receivers, with minimal interference from the enhancement portion of the EDTV signal, is described. 
     The black level of the NTSC portion of an EDTV broadcast signal is set to a level N, typically twice as high as the normal 7.5 IRE units. This signal characteristic motivates the viewer or the automatic black level circuits of the NTSC receiver to raise the receiver's black level to about the same N IRE units for optimum reception of the transmitted signal. EDTV enhancement signals are transmitted in the range of +N to -N (for example, +15 to -15) IRE units. Since the NTSC receiver is adjusted to blank all signals below N IRE, the EDTV enhancement signals between +N and -N IRE levels do not trigger the display in the NTSC receiver, thereby maintaining the upper and lower band areas at a uniform black level without unwarranted speckles or other interference.
