Title: Method for determining distance and direction from an open well to a cased well
Inventor: FREEDMAN ROBERT
IPC: G01V3/18
Filed: 1982-06-04
Abstract: A method for determining distance and direction from an open well to a cased well comprises: (1) utilizing resistivity logs obtained in the open well, and/or in the cased well before casing in run, to determine characteristics of earth strata Z to Zn penetrated by the wells, (2) determining the actual trajectory of the open well from survey data, (3) determining theoretically expected resistivity curves for long and short spaced electrode-type tools A, M, N at various depths in the open well for different assumed positions of the cased well relative to the open well, (4) determining measured resisitivity curves for tools A, M, N by logging the open well, (5) varying the assumed relative positions of the open and cased well to adjust the spacing of the curves until the expected and measured curves match in a best fit mathematical sense; the amount of variation in assumed relative position required to match the curves determining the distance of each station in the open well to the cased well, and (6) determining the direction of the cased well from the open well by constructing a plan view of the open well trajectory from the survey data and utilizing the distances previously determined. <IMAGE>

Title: Cladding of roofs and walls
Inventor: JERRARD-DUNNE ANDREW PETER
IPC: E04D3/36
Filed: 1982-07-23
Abstract: A cladding assembly in which sheets of external cladding material 26 are fixed to frame members of a building, such as purlins 10. The cladding assembly consists of I- section support beams 20 which extend transversely to the purlins 10 and which support sheets 22 of thermally insulating material. Spacers 24 engage the support beams 20, each spacer being aligned with one of the purlins 10. The cladding 26 is laid against the spacers 24 and held in place by fixing elements such as self- tapping screws 28 extending through the cladding, spacers 24 and insulating sheets 22 and engaging the purlins 10. Since the cladding 26 is held spaced from the insulating sheets 22, which support only their own weight, insulating material of low structural strength, such as polyisocyanurate board, can be used. The fixing elements 28 can be inserted from outside, thus facilitating installation of the assembly. <IMAGE>

Title: Monitoring oestrus in animals
Inventor: WRIGHT THAD F
IPC: G06K19/067
Filed: 1983-10-07
Abstract: To monitor livestock for artificial insemination purposes, a transmitter 101, 102 or 103 is fastened to the female animal, such as a cow, to generate a signal when simulated mounting of the animal takes place. The signal is received by a receiver 10 at a distant point and is recorded as a print-out 11 for interpretation of the phase of the animal's fertility cycle. The transmitter 101, 102 or 103 includes time delay circuitry which causes the transmitter to pause for a predetermined time before signal generation. Switch means comprising a permanent magnet 13 on a resilient member 14 adjacent a Hall effect magnetic switch 15 is mounted on a cow being monitored so as to be actuated by the pressure of the breast bone of the cow performing simulated mounting. Closing of the switch activates the transmitting means, and cut-off means within the transmitter terminates its activities after signal generation to conserve energy.   <IMAGE>

Title: Dc brushless electromagnetic rotary machine
Inventor: YOSHIDA MAKOTO
IPC: H02K29/00
Filed: 1984-03-26
Abstract: A dc brushless electromagnetic rotary machine, such as a dc electric motor, a dc electrical generator, includes a rotor having a permanent magnet which is cylindrical outer peripheral surface magnetized in the same polarity. The outer surface faces armature cores fixed on the inner cylindrical surface of a casing frame forming a stator of the machine. In the structure, the magnetic flux emanating from the rotor magnet passes the armature cores and returns to the magnet from a position other than the armature cores. The armature core is provided with coil windings wound thereon in such a manner that a portion of the windings is included in the air gap formed between the rotor magnet and the cores. Additional magnetic flux induced in response to current flowing over the armature windings causes the main magnetic flux generated from the rotor magent to be turned in the same way irrespective of the angular position of the rotor. Consequently, continuous rotation of the rotor will be accomplished in the case of dc motors, and continuous generation of dc power will be achieved in the case of dc generators.

Title: Improving the nutritive value of products
Inventor: GRIEFF JOHANN THEODOR
IPC: C12C5/02
Filed: 1984-07-04
Abstract: The nutritive value of products formed by or with the aid of fermentative organisms is increased by improving the availability for ingestion by humans or animals of the vitamin B content of cells of yeast and other fermentative organisms included in the product by killing such cells. The cells of the fermentative organisms are killed by subjecting the product to mechanical communication in, e.g., a ball-mill type disintegrator, resulting in mechanical rupturing of at least a part of the yeast cells. Alternatively, yeast is separated from freshly brewed beer and subjected to mechanical comminution. The cell debris is separated from the comminuted yeast and the liquid phase is returned to the beer. A percentage of live fermentative cells may be retained in the product, or live cells added to the product, in order to achieve a satisfactory degree of effervescence therein.
