Abstract: A CF ink and process which can be applied to a support sheet by standard transfer-litho press is provided. The nonvolatile printing ink which is capable of color development may be used to produce a CF carbonless copy sheet, or, in combination with a high solids, aqueous-based CB ink, to produce a CFB carbonless copy sheet. The ink includes from about 25 to 35% of a non-volatile oil, 25 to 35% of an acidic color developer, 20 to 50% filler, and 4 to 15% dispersed wax particles, all percentages by weight.

Abstract: An identification of friend from foe (IFF) device is described containing a radio transceiver (F) which, in addition to being designed for communication purposes, is equipped for transmitting, receiving, and evaluating IFF signals. The IFF device further includes a laser transmitter (LS) and an optical receiver (LE) which are coupled to the radio transceiver (F) via a controller (G). For identification, unmodulated direction-selective light signals and modulated nondirectional radio signals are used.

Abstract: In radio operation in tactical use, an increased jamming resistance with respect to intentional jamming is required. For protection against intentional jamming, frequency hopping techniques have proven very advantageous in which the signals are transmitted in the form of successive error-protected signal blocks where each signal block is transmitted on a different radio carrier frequency which changes in a pseudo-random manner. With this technique, phase shifts can occur which are greater than half a bit and therefore make analysis of the signal blocks difficult or impossible. It is proposed herein that each received signal block be checked after regeneration in a regenerative repeater, controlled by a bit clock pulse, as to its correct block phase and therefore, respectively, newly establish the block clock pulse phase required for further accurate processing of a signal block.

Abstract: A method of controlling the ill-effects of ground bounce in a CMOS device, according to the present invention, comprises increasing the impedance between (1) the output line of a quiescent channel that is already at a low state, and (2) the local ground within the CMOS device; the increased impedance occurring when a ground bounce condition caused by an adjacent channel within the CMOS device would otherwise cause the output of the quiescent channel to be dragged high.

Abstract: A fiber-optic sensor is formed from three optical fibers. The distal ends of the fibers are optically linked by bonding their cores and directing their ends to mirrors. A portion of one of the fibers near the bonded point is exposed directly to the fluid to be sensed. The transmission characteristics of this fiber, the signal fiber, is then affected by the chemical constituents of the fluid. Light directed into the proximal end of one of the other fibers, the input fiber, is split between the signal fiber and the remaining fiber, the reference fiber. The ratio of the light in the signal fiber to the light in the reference fiber provides an indication of the chemical constituents that minimizes errors introduced by factors such as bends in the fibers and temperature.

Abstract: Polymers are disclosed which comprise the reaction product of (A) at least about 60 weight percent of at least one .alpha., .beta.-unsaturated polycarboxylic acid or anhydride; and (B) about 0.5 to about 40 weight percent of at least one acrylamide represented by the formula VI:CH.sup.2 .dbd.C(R.sup.5)C(O)N(R.sup.6)R.sup.7 (VI)wherein R.sup.5, R.sup.6 and R.sup.7 are each independently hydrogen or lower alkyl groups provided that at least one of R.sup.6 and R.sup.7 is a lower hydro-carbyl group, and further provided that the mixture is free of a vinyl sulfonic acid. The monomers react at elevated temperatures to form polycarboxylate scale inhibitors having a number average molecular weight of from about 400 to 10,000. The polymers have particular application in the inhibition of scales during oil field operations, but also may be employed in any environment where deposition of mineral scales is undesirable.

Abstract: A method of determining and controlling a load by a controller. The method comprises the steps of transmitting a signal for a first predetermined time period on an electrical line having a load in parallel with a capacitor; monitoring the electrical line for electrical activity within a second predetermined time period following the first time period; and controlling the load in response to the presence or absence of the electrical activity.

Abstract: Oxygen is separated from an oxygen-containing gas by introducing the gas into a first zone of a gas separation apparatus, the apparatus comprising first and second zones separated by a mixed metal oxide membrane, the membrane having a first surface open to the first zone, a second surface open to the second zone, and an empirical formula ofBiA.sub.x M.sub.y M'.sub.z O.sub.nwhere A is at least one of Mg, Ca, Sr, Ba, Y, Th, U, and the lanthanide elements; M is at least one of Sc, Ti, Cr, Mn, Fe, Ni, Cu and Zn; and M' is at least one of Co, Rh, Pd, Pt or Ru. The oxygen separated from the oxygen-containing gas can be recovered from the second surface of the membrane either as molecular oxygen, or it can be reacted with an oxygen-consuming substance, such as a hydrocarbon gas, which can be introduced into the second zone of the separation apparatus and brought in contact with the second surface of the membrane.

Abstract: A cable (C) is laid in a pipeline (10) by pushing the cable and (C') through a hydraulically variable diaphragm in an inlet tube (11). The end (C') of the cable has collapsible moulded cups (20) attached which can be pushed through the diaphragm and which erect themselves to act as a drag inducing device so that flowed liquid in the pipeline can be used to pull the cable and (C') towards an exit tube (12) downstream. A cable pusher (13) pushes the cable through the inlet (11). The cable has a specific gravity less than the liquid, preferably 0.7, which is substantially pressure independent.
