摘要： Piezoelectric ladder filters with the following characteristics are described: A. The filter selectivity may be changed without changing the resonators and without requiring the frequencies of peak insertion loss to be changed. This type of filter will be referred to as ''''equal-resonator filter.'''' B. Except for the restrictions on the series resonant frequency of the shunt resonators and the anti-resonant frequency of the series resonators, the remaining resonator parameters are largely, within a range that will be explained, independent of the filter selectivity. This permits use of predetermined resonators for the design of filters with different selectivity characteristics. It includes filters where all the series resonators and all shunt resonators, respectively, are equal, as well as filters in which all the resonators are identical with each other. The latter type will be called ''''identical resonator'''' filters.

摘要： Two coaxially disposed rigid tubes are interconnected by a radially secured elastomeric spring member with a fluid chamber formed in the inner tube as well as in the outer tube. The elastomeric member is effective upon relative axial movement between the two tubes to change the volumetric relationship between the two chambers by causing fluid to flow through differently sized orifices within the inner tube. An elastomeric compression bumper is disposed axially between the tubes and upon movement between the tubes of a certain magnitude, the bumper progressively covers some or all of the orifices. The elastomeric spring member provides one or more dissimilar spring rates. Additional load carrying capacity is provided by a gas pressure chamber within the inner tube.

摘要： Recording electrodes of a coincidence voltage type electrographic recorder are divided into arrays. Arrays are divided into two or more groups and are interleaved so that no array is adjacent another array of the same group. Like-numbered electrodes of each array in a group are connected together. Complementary electrodes are disposed adjacent to the arrays. Each is adjacent to only one array of a group and is spaced from all other arrays of the same group. A latent image is formed at one selected recording electrode when suitable voltage is applied to that electrode, and in coincidence therewith, suitable voltage is applied to complementary electrode means adjacent to the selected recording electrode.

摘要： An electrographic imaging system is provided for producing an electrostatic latent image upon an electrographic record medium having dielectric and conductive layers. Electrostatic charging means are provided comprising an array of charging electrode means, some of which are interconnected and thereby are connected to fewer first voltage source means than the total number of charging electrode means in the array. Also provided is an array of complementary electrode means which is connected to second voltage source means. The energized complementary electrode means are capacitively coupled to the conductive layer of the record medium to change the potential thereof upon a voltage pulse being applied to the complementary electrode means. The energized charging electrode means charge discrete areas of the dielectric layer of the record medium only when the complementary electrode means simultaneously are connected to the second source of voltage to effect the capacitive coupling. Also, heads are provided wherein an array of small electrical conductors is supported in a dielectric material in closely spaced relation to each other with the end faces thereof exposed and substantially flush with the support. Complementary electrode means are mounted on the support adjacent to but spaced from the end faces of the electrical conductors and form with the support means a substantially flush, smooth surface over which the record medium can move. Electrical Contacts for both the small electrical conductors and the complementary electrodes are provided in the support.

摘要： A multichannel strip chart recorder has a commutator to sequentially sample signals at a plurality of channels and apply the samples to a single-pen recording device. A spring-biased actuator holds the pen off the chart during commutation. A solenoid overcomes the spring allowing the pen to record a dot for each signal sample. Thus, each signal is recorded as a trace made up of a series of dots. Trace-identifying symbols are preprinted sequentially and repetitively along an edge of the chart in predetermined relation to the chart sprocket holes. As each symbol moves into approximate alignment with the path of the recording pen tip the solenoid action is inhibited by signals from electro-optical devices sensing the positions of sprocket holes and notches at the edge of the chart so that the trace identified with that symbol is interrupted. When the signal at one channel has higher frequency content than the signals at other channels, the commutator sequence may be arranged to sample that signal more often than the signals at other channels.

摘要： An oscillator circuit is provided for ultrasonic apparatus such as ultrasonic cleaners employing a resonant transducer. The circuit includes a pair of transistors connected in series to a source of power with the transducer connected across one of the transistors in series with the primary winding of a transformer which has secondary windings connected in opposite polarity to the bases of the transistors so that one transistor is saturated while the other is nonconducting. The circuit accordingly oscillates at substantially the resonant frequency of the transducer as a result of the feedback provided by the secondary windings of the transformer.

摘要： An integral battery of serially connected photovoltaic cells on a single insulating substrate. Metallized areas are formed on the substrate with semiconductive film such as cadmium sulfide vacuum evaporated upon each of the metallized areas. Barrier layers are formed on the cadmium sulfide films to produce PN junctions. Electrode leads extend from each metallized area under the semiconductor film to a top surface of the barrier layer of an adjacent semiconductor film.
