Abstract: An electrical telephone speech network is disclosed in which the transmitting and the receiving amplifiers are serially connected so as to reduce the minimum working current of the whole speech network. As a result, a telephone set in the network can operate properly with a much lower line current, and more extension telephones can be connected parallelly with the speech network. Further, a bias switching circuit is matched with the speech network. Thus, in pulse dialing mode, the line voltage drop of the network loop during "make" status is automatically decreased so that a pulse dialing signal received by the exchange can be more accurate. At the same time, in DTMF dialing mode, the voltage drop of the telephone set is automatically increased, for the purpose of providing a larger AC signal dynamic range to enable a telephone set to deliver a larger DTMF signal and operate with a lower line current. Also, owing to direct coupling for feeding DTMF sidetones, the subscriber receives a signal with the least distortion and most stable DTMF sidetone volume.

Abstract: A foam material dispensing system is provided with a control (20) which measures the amount of high viscosity liquid material delivered to a mixer (24), determines the amount of pressurized gas required to be injected into the mixer in order to produce a foamable material with a desired gas concentration, measures the amount of gas actually delivered to the mixer, and generates a cumulative error signal representing the difference between the amount of gas and the gas actually delivered. A control signal is generated to regulate the flow of gas to the mixer in relation to the magnitude of the error signal. A digital flow meter generates a pulse for each incremental amount of liquid material delivered to the mixer during an interval of time. During each successive interval, the pulses are counted and the count is multiplied by a preset gas-to-material ratio, from which the measured gas flow is subtracted and the difference added to the cumulatie error term. The error term is combined with a term proportional to the amount of liquid material delivered over a predetermined number of successive time intervals to produce the control signal.

Abstract: The present machine (1) has a device for repeating the selection of the needles at least at one thread feed, which includes a memory element (12) arranged proximate to the lower end of the selectors (5), which can oscillate in a plane radial to the needle cylinder (2) by virtue of the action of selection levers arranged upstream of a thread feed of the machine (1), according to the direction of the rotation imparted to the needle cylinder (2) about its own axis (2a). The selectors (5) can individually oscillate in a radial plane with respect to the needle cylinder (2) from an extraction position, whereat they protrude from the needle cylinder (2) with a main heel (5a) so as to engage actuation cams (7) arranged about the needle cylinder (2), to a sunk position, whereat they do not engage the cams. The memory element (12) is controllably movable from an inoperative position, whereat it does not interfere with the oscillation of the selectors (5), to an operative position whereat, between two feeds of the machine (1), it maintains the position of the selectors (5) imparted by the selection levers upstream of the first feed so that the performed selection is maintained at the second feed as well without requiring a new selection.

Abstract: Radio frequency energy detection circuitry (10) changes the logic state of its output signal at a terminal (12) from an initial state to a second state in response to received radio frequency energy exceeding a first predetermined power level. The circuitry (10) does not respond to fades in such received radio frequency signal because the second state of the output signal is prevented from reverting to the initial state until the power level of the received radio frequency energy falls below a second, lower predetermined power level. The input energy is converted into a voltage by a detector diode (18). This voltage is compared (26) with the prevailing threshold voltage (V R ) to determine the output logic state. The output logic state is fed back by a resistor (R S ) to the threshold voltage input terminal (25) and is such as to establish the second, lower predetermined power level in response to the received radio frequency energy exceeding the first predetermined power level.

Abstract: On the transmission side, a delay unit (101), an adder (102), and a subtracter (103) obtain an interframe sum output by calculating, in units of two frames, an interframe average sum of progressive scanning signals each having N scanning lines [per frame], and an interframe difference output by calculating, in units of two frames, an interframe average difference related to moving image data. The interframe sum output is band-limited to a band which can be transmitted with a conventional scheme by switching, time expansion, vertical filtering, and first scanning line count conversion, and converted into M scanning lines [per frame]. The interframe difference output is band-limited to a band effective for resolution improvement of a moving image in a receiver of a conventional scheme by switching, time expansion, vertical filtering, horizontal filtering, and second scanning line count conversion, and converted into M scanning lines [per frame]. Outputs obtained by first and second scanning line count conversions are input to a sum arithmetic means (124) to generate a first frame signal, and input to a difference arithmetic means (125) to generate a second frame signal. The first and second frame signals are transmitted as an interlace scanning signal of M scanning lines [per frame] for a central portion thereof.
