Abstract: A note pad and method of fabricating the same. The note pad is characterized in including a plurality of sheets for carrying written messages, each of which is adhesively retained in the assemblage by a pretensioned length of polymeric tape. Discrete sheets are removable from the assemblage in complement with a length of the tape affixed thereto to permit a facile posting thereof at a prominent location. Curling of the pads due to the noted tape pretensioning is avoided by the development of a laminar, structurally rigid compilation of discrete lengths of the tape during fabrication procedures. By pretensioning the tape, undesirable rippling effects otherwise developed during fabrication are avoided.

Abstract: A system for mounting thin transparent membrane material over the interior of a window to provide an insulating effect. An elongate narrow retainer molding is positioned along the peripheral frame portion of the window. This molding includes a narrow base portion having a flat surface intended for adhesive and permanent attachment to the frame. Integrally formed with the base portion are two side components which extend upwardly to a top surface which is shaped concavely to define a receiving region. Detents are formed in these side portions which extend over a centrally disposed groove. A beading of circular cross-section is urged with the peripheral portion of the membrane into the centrally disposed groove to provide a non-adhesive form of fixation of the membrane to the retainer molding.

Abstract: The method consists in subjecting a sample of insulating material to photon radiation and in measuring the energy of the photoelectrons emitted by the sample under the action of the radiation. The sample is fixed on a metal sample-holder having a shape such that a portion of this latter is subjected to radiation. The emission of electrons of low energy is thus initiated and the positive charges which appear at the surface of the samples with the emitted electrons are neutralized by creating in the vicinity of the sample surface a space zone in which the electric field is substantially zero.

Abstract: A flight control type system which provides a tactile readout to the hand of a pilot for directing elevator control during both approach to flare-out and departure maneuvers. For altitudes above flare-out, the system sums the instantaneous coefficient of lift signals of a lift transducer with a generated signal representing ideal coefficient of lift for approach to flare-out, i.e., a value of about 30% below stall. Error signals resulting from the summation are read out by the noted tactile device. Below flare altitude, an altitude responsive variation is summed with the signal representing ideal coefficient of lift to provide error signal readout.

This internal angle configuration is used both to provide peripheral support for the signboards and supply necessary structural rigidity to the assembly, thereby minimizing the number of components thereof.

Abstract: A resistor placed between the input and output of a first circuit has a low value when a control signal delivered by a threshold discriminator circuit has a first value and has a high value when the control signal has a second value. The input of an amplifier A.sub.3 of the first circuit is connected through a switch either to the output of a first amplifier A.sub.1 or to the output of a second amplifier A.sub.2. The first amplifier has a negative input connected to a coupling capacitor of the first circuit and to the output of the amplifier A.sub.3 and a positive input connected to ground. The amplifier A.sub.2 has a negative input connected to the output of the amplifier A.sub.3 and to ground and a positive input connected to the negative input of the amplifier A.sub.1.

Abstract: The device comprises a first dry seal and an admission chamber for controlled leakage of a neutral barrier gas at a pressure of slightly higher value than the pressure of the hazardous gas which is thus prevented from passing through the seal. The pressure difference across the first seal is maintained at a low and constant value by an external regulator. A second seal closes the admission chamber and is supplied with barrier gas at a pressure of higher value than the pressure of the external atmosphere. Leakage of the barrier gas from the second seal is discharged along with any leakage of hazardous gas through the first seal into an external recovery circuit. The leakage of barrier gas from the admission chamber is into an adjacent compartment defined by the second seal and by a floating ring which produces a pressure drop so as to prevent the external atmosphere from penetrating into the compartment.

Abstract: An apparatus and method wherein an electrical impulse source transmits a radar-type signal through an antenna into the ground and is reflected by a target. The reflected signal or echo is detected by the antenna and an analog-to-digital converter converts it to a digital form which may be readily operated on, stored and recalled. A memory stores the information until recalled for comparison with a subsequent signal to give an indication of the location of metallic and non-metallic buried targets.

Abstract: A gamma camera system having control components operating in conjunction with a solid state detector. The detector is formed of a plurality of discrete components which are associated in geometrical or coordinate arrangement defining a detector matrix to derive coordinate signal outputs. These outputs are selectively filtered and summed to form coordinate channel signals and corresponding energy channel signals. A control feature of the invention regulates the noted summing and filtering performance to derive data acceptance signals which are addressed to further treating components. The latter components include coordinate and energy channel multiplexers as well as energy-responsive selective networks. A sequential control is provided for regulating the signal processing functions, of the system to derive an overall imaging cycle.

Abstract: A composite solid-state detector for utilization within gamma cameras and the like. The detector's formed of an array of detector crystals, the opposed surfaces of each of which are formed incorporating an impedance-derived configuration for determining one coordinate of the location of discrete impinging photons upon the detector. A combined read-out for all detectors within the composite array thereof is achieved through a row and column interconnection of the impedance configurations. Utilizing the noted read-outs for respective sides of the discrete crystals, a resultant time-constant characteristic for the composite detector crystal array remains essentially that of individual crystal detectors.
