    Abstract: An FM discriminator useful in a modem circuit includes a tank circuit coupled to an input receiving an FSK input signal. The FSK input signal is resistively coupled to an input of an operational amplifier having its output also coupled to that input. The other input of the operational amplifier is connected to the tank circuit and to an input of a comparator. The other input of the comparator is connected to the output of a circuit which produces a signal that lags by 90 degrees the signal produced by the tank circuit. The output of the comparator is used to synchronously chop the output signal of the first operational amplifier in such a way as to pass the operational amplifier output signal when the comparator output signal is a "1" and to invert the operational amplifier output signal when the comparator output signal is a "0". The tank circuit resonates at a frequency between the "0" and "1" frequencies of the FSK signal and, in combination with the operational amplifier, causes attenuation of components of the FSK input signal which are at the resonant frequency.

    Abstract: A combustor liner includes a wall having an outboard surface and an opposite inboard surface. A plurality of first holes are inclined through the wall in a multihole pattern to channel cooling fluid therethrough to form a cooling film layer along the inboard surface. A second hole extends perpendicularly through the wall within the multihole pattern to form a shadow along the inboard surface devoid of the first holes. A transition hole extends through the wall in the shadow at a greater inclination than the first holes for cooling the wall at the shadow.

    Abstract: A first connector (12, FIG. 2) is constructed so when it is unmated from a second connector (14), front contact devices (32) of the first connector are switched from connections to conductors (16) leading to circuit component (70) to connection to a ground plane (110). The first connector comprises a front insert assembly (22) that includes a plurality of front contact devices (32), and a rear insert assembly (50) that includes a plurality of rear contacts (62). When the second connector fully mates with the first one (FIG. 3), the second connector pushes the front insert assembly to a rearward position (22B), against the force of a spring (40), to cause the front contact devices to mate with the rear contacts. When the second connector unmates from the first one, the spring moves the front insert assembly to the forward position. During forward movement, the front contact devices engage the ground plane (110), to thereby ground the front contact devices when they are not mated to the rear contacts.

    Abstract: An apparatus for controlling weeds and undergrowth by the application of hot water thereto. The apparatus is particularly characterized by its construction including an endless, ground-engaging belt, or apron, disposed immediately aft of the hot water spray. Thus, when hot water is sprayed on the weeds and undergrowth, the sprayed vegetation is not only compressed by the apron, but also heat from the water is retained therein, insulated from ambient conditions by the apron.
