Abstract: PROCESS FOR THE PRODUCTION OF OPTICAL FIBER PREFORMS    ABSTRACT OF THE DISCLOSURE    An improved process for the production of optical fiber  porous  preforms  of  predetermined  refractive index  distribution  by  the  vapor-phase  deposition method is disclosed wherein a glass material and a dopant material are subjected to flame oxidation by the use of an oxyhydrogen burner to form fine glass particles which are deposited on one end of a support-ing rod adapted to move apart from the oxyhydrogen burner  while  rotating  to  allow  a  rod-like  porous preform to  grow  thereon.  The improved process is characterized  in  that  the  correlation between  the shape of the deposition face and the refractive index distribution is previously determined mathematically, and on a basis of the correlation therebetween,  a process  variable  such as the distance between the porous preform and the burner is adjusted to produce the  desired  shape  of  the  deposition  face  whereby there  can be obtained an optimum refractive index distribution.

Abstract: METHOD AND SYSTEM FOR MONITORING THE DISPENSING OF DRUGS OR NUTRIENTS TO ANIMALS          Abstract of the Disclosure The disclosed system comprises one or more stationary dispensers associated with drinking fountains for farm animals, for dispensing predetermined doses of drugs or nutrients, operating in cooperation with a plurality of portable units constructed for individual animals.  The portable units are designed to interact electronically with a stationary dispenser to control the amount and timing of the doses.  The stationary dis-penser includes in circuit relation, an interrogator-transmitter, a reply receiver, and a liquid dispenser responsive to the reply receiver.  Each portable system comprises a coded passive transponder, a timer, and a memory element.  When an animal comes within range of the stationary dispenser, its portable transponder is interrogated.  A coded reply is sent by the animal's transponder indicating whether animal has received a dose within a proceeding preselected time interval.  If a positive reply is received by the stationary dispenser circuit, no further action is taken.  The animal may drink but no dose of medication or nutrient will be dis-pensed.  If a negative reply is received, then the dispenser valve is enabled, releasing the desired pre-measured dose if the animal drinks.  Operation of the dispenser valve also causes a coded signal to be trans-mitted from the interrogator-transmitter to the animal's portable unit setting a memory element, indicating that the animal has received the required dose, and initiating the running of the preselected time period, after elapse of which, the memory element is reset for enabling the next dosage.

Abstract: APPARATUS FOR DRIVING AN OSCILLATING SPOUT     Abstract of the Invention A drive means for an oscillating spout is presented which includes a control mechanism which directs a control arm to perform the movement required by the spout and a transmission device which acts to transmit the control arm movement and reproduce it as spout movement.  The control mechanism consists of a driving rod pivotally connected to an intermediate lever arm and a novel universal joint connecting the lever arm to the control arm.  The universal joint enables the spout to be moved in and out of a vertical orientation by prohibiting the components of the control mechanism from becoming axially locked in a 180° angle.

Abstract: DEEP PENETRATION WELL LOGGING SYSTEM AND METHOD               ABSTRACT OF THE DISCLOSURE           A well logging system and method of the present invention determines the dielectric constant and/or conductivity of earth formations some of which have fluid invasion.  The system and method of the present invention includes the transmission of electromagnetic energy into the earth formation from a first location in a borehole in the formations at a frequency which enables the electromagnetic energy to propagate throughout the surrounding earth formations.  Electromagnetic energy is received by receivers at three locations in the borehole which are spaced longitudinally from the location of the transmission of the electromagnetic energy.  The receivers provide signals representative of the total electromagnetic fields at those locations.  The dielectric constant and/or resistivity of the earth formations are determined in accordance with portions of the signals from the three receivers corresponding to secondary electromagnetic fields at the three receiving locations.

Abstract: CENTRIFUGAL PUMP                       Abstract A centrifugal pump has a casing with an impeller cavity in which a shrouded impeller is mounted and with front and rear labyrinth seals associated one with each of the front and rear shrouds of the impeller and located near the inner ends of the shrouds. An additional seal is positioned inwardly of the rear labyrinth seal to substantially seal a space behind the innermost part of the rear shroud and a pump structure is mounted on the impeller to the rear of the rear shroud for pumping fluid from the substantially sealed space to the entrance of a volute surrounding the im-peller. The impeller shaft has a front thrust bearing coacting with a bearing surface, with fluid passing therebetween for lubrication and with the flow of the fluid being controlled to a minimal amount by a force imbalance on the impeller shaft created by location of the front and rear labyrinth seals at different distances from the axis of rotation of the impeller whereby pres-sure forces acting at the rear of the impeller urge the impeller shaft in a forward direction.

Abstract: SINGLE PIECE PRE-SHAPED WALL ANCHOR            Inventor:  Louis N. Giannuzzi, a citizen of the United States of America and resident of Cos Cob, Connecticut ABSTRACT OF DISCLOSURE A one-piece wall anchor capable of being driven axially into a hole drilled in masonry to cause the inserted anchor to lodge securely therein to hold a fixture or other part against the masonry surface.  The anchor is constituted by a shank formed of resilient material whose memory is such that when the shank is forcibly deformed, it seeks to maintain its original shape, the shank being integral with a drivable head and having a maximum cross section which is substantially equal to the diameter of the hole.          The shank is pre-shaped to include at least one undulation which deviates from the longitudinal axis passing through the head to create a shank bend having a peak on one side of the shank and upper and lower bases on the other side thereof.  When, therefore, the anchor is driven into the masonry hole, this force seeks to straighten out the bend, the resultant deformation thereof exert-ing outward pressures against large contact areas on the wall of the hole at the peak and at the bases of the bend, which multi-level pressures strongly resist axial withdrawal of the shank.
