Title: Well logging methods and systems
Inventor: RUCKEBUSCH GUY B
IPC: G01V5/06
Filed: 1983-08-30
Abstract: Disclosed are a method and a system for well logging in which gamma radiation detected 10 in five energy windows is converted into logs of formation thorium, uranium and potassium (Th, U, K), and logs of borehole barite and potassium chloride (KCl), in a process which makes use of an adaptive filter 24 having a model which accounts for changes in the detected gamma radiation with borehole depth, for the nature of the logging process, and for the composition of the borehole fluid. In a first, simpler embodiment, the adaption of the filter is based on changes with borehole depth in the total amount of detected gamma radiation in the vicinity of the depth level of interest. In a second, more exacting embodiment, the filter is based on a model of both the vertical variations in the Th, U, K concentrations, and the statistical variations in the measurements. In both embodiments a log of Th, U, K is produced. A third embodiment which accounts for environmental effects is based on the second embodiment, but additionally incorporates into the model the effect of the borehole size and the influence of the gamma ray emitters and absorbers located in the borehole fluid on the detected counts of the energy windows. The third embodiment permits the converting of the received radiation information into logs of formation thorium, uranium and potassium, and logs of borehole barite and potassium chloride, by borehole depth. The invention relates to induced as well as natural gamma radiation, and to other types of well logging in which energy windows can be measured, such as sonic well logging. <IMAGE>

IPC: A01J5/013
Filed: 1983-03-16
Abstract: An electrical conductivity testing device for detecting mastitis in dairy cows includes an inlet (56) for receiving a sample of milk to be tested, a conductivity cell (60) having a milk flow-through testing passage (59, 61, 62) in flow communication with the inlet, and a milk discharge outlet (65) in flow communication with the conductivity cell, so that a milk sample enters the inlet, flows through the conductivity cell, and flows out through the discharge outlet. The flow described may be continuous or may be discontinuous so that the sample is held in the conductivity cell at least during taking of the conductivity measurement. The conductivity cell is arranged so that it is completely filled with milk during the taking of conductivity measurements. Electrical circuitry is provided to produce an electrical signal proportional to the conductivity of the milk in the conductivity cell. A preferred embodiment of the device takes conductivity measurements, individually and sequentially, of samples of milk from the four quarters of a cow's udder and produces electrical signals representing respective individual conductivity measurements on a scale of from 0 to 9 by electrical comparison of such conductivity measurements with a reference value (31), preferably by means of a bridge amplifier circuit (16, 31, and 32), and exhibits respective digits representative of such measurements, preferably side-by-side, on a readout screen (25) provided as a part of the instrument.

Title: Method and apparatus for starting rotation of a disc-drive motor in a disc memory device
Inventor: SLEGER ROGER R
IPC: G11B21/21
Filed: 1985-10-24
Abstract: To reduce the starting torque required from a disc-drive motor in a contacting-head disc memory device, a dithering motion is applied to the head assembly (8) of the device during the start-up of the disc-drive motor. This dithering motion is effected by using the head positioner motor and is continued at least until the head assembly (8) has lifted off the rotating disc (5). Also the effects of large variations of torque of disc-drive motors with respect to the rotational angle and of substantial variations in friction due to non-uniformity of the wear layer on the disc (Fig 3), are alleviated.   <IMAGE>
