Abstract: METHOD OF PRODUCING A GLASS ARTICLE HAVING A GRADED REFRACTIVE          INDEX PROFILE OF A PARABOLIC NATURE          ABSTRACT OF THE DISCLOSURE:     A method of producing a glass article having a graded refractive index profile of a parabolic nature is disclosed.          The method comprises soaking a preform having a porous matrix with interconnected pores into a stuffing solution containing at least one index modifying dopant of predetermined solubility in the stuffing solution for a time interval to fill the pores with the dopant solution, precipitating the dopant into the porous matrix approximately uniformly throughout, soaking the preform into a solvent solution having a solubility for the dopant lower than the solubility of the dopant in the stuffing solution for a time interval sufficient to cause substantially all of the dopant to redissolve and for diffusion to take place out of the porous matrix in such a way that the dopant concentration decreases as a function of radial distance from the central axis, precipitating the dopant in the porous matrix by reducing the temperature of the preform to a level such that the dopant is precipitated out of solution, removing the solvent and where necessary decomposi-tion products from the preform, and heating to consolidate the preform to produce a glass article having a graded refractive index profile of the parabolic nature.

Abstract: ABSTRACT OF THE DISCLOSURE   The variable speed transmission includes a power input drive shaft and a variable throw crank having a zero throw position aligned with the in-put shaft.  The variable throw crank is coupled to the input shaft for ro-tation therewith and its eccentricity with respect to the axis of rotation of the input shaft can be varied.  A control plate, also referred to as a master link, is rotatably mounted on the crank and a plurality of clutches having input and output shafts are operatively connected to the control plate through a plurality of pitman type links, whereby the control plate oscillates the input shafts of the clutches upon rotation of the power input shaft and variable throw crank of the transmission.  The outputs of the clutches are connected to an output shaft for the transmission.  By varying the throw of the variable throw crank the ratio between the rotary speed of the output shaft can be infinitely adjusted from zero to a maximum ratio de-termined by the maximum eccentricity of the variable throw crank with re-spect to the axis of rotation of the input shaft.  A preferred embodiment is to revert the above.

Title: Nmr analysis of subterranean reservoir samples  immersed in liquid halocarbons
Inventor: MESHRI INDURANI D

Granted: 1982-07-13
Abstract: ABSTRACT OF THE DISCLOSURE A sample of a subterranean formation is prepared for NMR analysis by saturating the sample with an aqueous liquid and then immediately immersing it in a liquid halo-carbon.  An NMR analysis is conducted on the immersed sam-ple.  The liquid halocarbon does not have hydrogen atoms bound thereto which would interfere with the NMR analysis and preferably has a sufficient viscosity to substantially eliminate the displacement of aqueous liquid from the sam-ple.  The sample can be stored in the liquid halocarbon for maintaining aqueous liquid within the sample.

Abstract: ABSTRACT     A cartridge is provided for applying staples to the disunited fascia of a patient.  The cartridge is adapted to associate with a surgical stapling instrument which supplies rectilinear thrust to power the cartridge.  The cartridge houses a plurality of staples mounted on a flexible belt.  A pusher is slidably mounted in the cartridge for forming the staples around an anvil.  The spring pawl associated with the pusher moves the staples into a position ready to be fired as the forwardmost staple is being formed around the anvil.  As a staple is formed around the anvil, a spring associated with the cartridge cover holds the staple against the anvil.  This spring also provides the function of ejecting the staple from the cartridge after it has been formed.  On the return stroke of the pusher, a spring pawl arrangement associated with the cartridge cover prevents the belt and staples from moving rearward away from the anvil.  The staples have a wide spacing between the points of the staple arms and enclose a large amount of fascia as the arms of the staples sweep through an arc as the staples are being formed.          Also, the staples are formed into a configuration in which the arms of the staples resist being pulled apart so that the staples will not be inadvertently disconnected from the fascia.

Abstract: ABSTRACT OF THE DISCLOSURE     A shielded flat cable useful as transmission line for example in computer back plane wiring and connection to peripherals, and in which electrical shielding is provided without substantial impedance shift while obtaining sub-stantial elimination of backward cross talk and significant reduction in forward cross talk.  This is accomplished utilizing cable cores which are flat multi-conductor electric cable components in which the body of solid dielectric material serving to retain and insulate the conductors has its parallel wide faces ribbed, i.e., convoluted about the conductors providing alternate lands and grooves running the length of the cable.  Flat spacer strips of solid dielectric material are positioned one on each face of the cable dielectric body abutting the lands, so that the spacer strips function to trap air as a dielectric between the lands in the grooves (and hence between the conductors as the conductors are positioned between lands in opposite faces of the cable core).  The electrical shield enclosing the cable component is completed with a sheath of electrically conductive metal positioned about the cable core including the spacer strips.

For transmitting those data, the length of the packet is always the maximum length and the value of the format byte is nil. In the described embodiment, there is provided a wire (269) from every channel to its associated coupler (267). That wire (269) may be at levels "1" or "0". The coupler comprises first switching means (268, 270, 273, 275, 277 and 278) for switching out counter (87) and memory (170). It includes a memory (281) storing a format byte the value of which is nil and second switching means (271, 276 and 279) to connect memory (281) to data memory (72) at any packet transmission, when wire (269) is at level "1". The reception equipment is modified accordingly.
