Abstract: Abstract of the Disclosure A miniature apparatus for compressing gases is disclosed in which an elastomer disposed between two opposing electrostrictive or piezoelectric ceramic blocks, or between a single electrostrictive or piezoelectric ceramic block and a rigid surface, is caused to extrude into or recede from a channel defined adjacent to the elastomer in response to application or removal of an electric field from the blocks.  Individual cells of blocks and elastomer are connected to effect a gas compression by peristaltic activation of the individual cells.  The apparatus is self-valving in that the first and last cells operate as inlet and outlet valves, respectively.  Preferred electrostrictive and piezoelectric ceramic materials are disclosed, and an alternative, non-peristaltic embodiment of the apparatus is described.

Abstract: ABSTRACT OF THE DISCLOSURE:           The security device of the invention comprises a movable organ in the interior of a cage mounted for rotation with respect to the body of a projectile, the movable organ being temporarily blocked from such rotation around the axis of gyration by at least one pin ejectable under the action of centrifugal force.  Said pin is itself retained by an elastic spiral hand enrolled upon the cage and which, as a result of a difference introduced into the speeds of respec-tive  rotation of the cage and of the body around the axis of gyration upon the exit of the projectile from the muzzle of the weapon, unwinds to liberate the pin.  As a result, the movable organ after a trajectory of many tens of after the pro-jectile has left the muzzle of the barrel of the weapon com-pletes the pyrotechnic train which fires the projectile.

Abstract: ENGINE PARAMETER MONITORING SYSTEM                         Abstract System for monitoring an engine operating parameter, such as oil pressure, which varies in proportion to engine speed, monitors the parameter relative to an upper and lower setpoint. Oil pressure is sensed by a transducer  and the sensed pressure  is monitored by a  pair of comparators  which compare the sensed oil pressure with reference voltages corresponding to the upper and lower setpoints.  The reference voltages may be selectively altered by a switch  in order to change the pressure setpoints. The outputs of the comparators  control  an annunciator  which indicates when the monitored pressure is below either of the setpoints.  A circuit  is provided to inhibit operation of the annunciator  by the comparators monitoring pressure relative to the upper setpoint when the engine's speed is below a predetermined value. The output of the comparator monitoring pressure relative to the lower setpoint controls a service-hour meter to provide an indication of the total elapsed time that the engine is running.

Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a method for reducing or preventing migration of a formation fluid from a first earthen formation to a second earthen formation each of which is intersected by a drilled bore hole.  The method includes running an inflatable packer in a string of casing into the bore hole, the packer including a mandrel with an elastic sleeve thereabout and a valve for permitting the flow from the interior of the mandrel into the interior of the sleeve to expand the sleeve against the formation.  The method further includes the steps of determining each of the pore pressure of the formation, the radial shrinkage of the cement within the sleeve, and the maximum pressure which can be exerted by the sleeve on the formation without fracturing same.  The method-further includes the step of pumping cement down through the casing and mandrel and into the sleeve at a pressure less than the maximum pressure that can be exerted on the sleeve without fracturing the same, but sufficient to resiliently strain the mandrel, sleeve, and formation in an amount sufficiently greater than the shrinkage of the cement during setting to provide a pressure of the sleeve against the formation, after the cement has set, greater than the pore pressure of the formation.

Abstract: ABSTRACT OF THE DISCLOSURE         A cleaning means is disclosed for textile surfaces, particularly textile floor coverings, containing a powdery, porous carrier material based upon urea-formaldehyde-resin foam which is enriched with cleaning agent, whereby the tenside-containing water adhered within the carrier material from the forming-up process is stored completely homogeneously in the carrier material, and forms together with the cleaning agent the prepared product.  It is suggested for lowering the free formaldehyde content, to add to the tenside-containing water adhering within the carrier material, which displays a pH-value less than 4 as well as a production-required free formaldehyde content of max. 0.2% by weight, a salt of sulfurous acid in an effective portion, relative to the anion of the acid, from 0.01-2% by weight, and urea from 0.1 to 5%. by weight.  This strongly reduces the portion of free formaldehyde and adjusts the pH-value of the cleaning means between 6 and 9.

Abstract: TECHNIQUE FOR VERIFYING GENUINENESS OF AUTHENTICATING DEVICE      Abstract of the Disclosure A given type of authenticating device operates as a diffractive subtractive color filter that exhibits a reflectivity spectrum that includes a peak occurring at a wavelength that varies as a substantially linear function of the angle of incidence of polychromatic illuminating light having a particular polarization.  The verification technique involves simultaneously illuminating a sample device over a range of angles of incidence by the polychromatic light, and then employing the light reflected from the sample to illuminate a reference device which is known to be genuine over the same range of angles of incidence.  A sample device is indicated as being genuine only if both the respective ratios of the intensity of light reflected from the reference device to the intensity of the illuminating polychromatic light and to the intensity of light reflected from the sample device exceed respective threshold values.

Abstract: Analysis of Reservoir Pore Complexes Abstract Analog signals corresponding to color images or pixels of a thin section of a rock reservoir are digi-tized and then filtered to isolate the pixels repre-sentative of pores in the thin section.  The pores so isolated are then counted, measured for their total pore perimeter and labelled.       The pixels representative of pores are then pro-gressively eroded and dilated, pursuant to which one layer of pixels on the surface is eroded and, if a seed pixel remains, one layer of pixels is added. Thereafter, the original object undergoes two suc-cessive erosions followed by two dilations if a seed pixel remains.  Successive iterations of the erosion and dilation cycle continue until the last erosion eliminates the seed pixel.  The number of pixels lost with each degree of erosion constitutes a pore spec-trum consisting of information relating to the total amount of pore image lost each erosion-dilation cycle, the pore size lost each erosion-dilation cycle and the pore roughness lost each cycle.      The spectra developed from the erosion-dilation cycle and corresponding to each pore complex are then analyzed into end members and the end member propor-tions for each field of view are calculated.

Abstract: MOULDING EQUIPMENT            Abstract of the Disclosure Moulding equipment in which cooperable male and female connectors of a mould and a dispensing container for mouldable material have means to lock them together.  This includes a locking member which is manually moveable in pivotal fashion upon one connector into and out of a locking position with the other connector.              Opposing surfaces of the locking member and the other connector relatively move across each other during movement of the locking member while offering sufficiently low resistance to movement to allow for manual operation.  During transfer of the material into the mould, the opposing surfaces are urged together by moulding pressure to increase resistance to movement of the locking member out of the locking position.  In preferred constructions, the locking member has a cam surface which ensures the need for a progressively increasing unlocking force to enable release of the locking member during transfer of the mouldable material.                           - i -
