Title: Borehole surveying
Inventor: RUSSELL ANTHONY WILLIAM
IPC: E21B47/022
Filed: 1983-04-09
Abstract: Using a survey instrument having its longitudinal axis coincident with the axis of the borehole, the survey instrument is rotated about the borehole axis at a survey station, and the components of the earth's gravity and the earth's magnetic field (gOX, gOY, gOZ, BOX and BOY) are measured along two non-coincident axes (OX and OY) transverse to the axis of the borehole for at least three different orientations (O) of the survey instrument about the borehole axis. At least one error correction value is determined from the results of these measurements (gOX, gOY, gOZ, BOX, BOY). The azimuth and inclination of the borehole are then determined at a plurality of points along the length of the borehole by measuring the components of the earth's gravity and the earth's magnetic field (gOX, gOY, gOZ, BOX and BOY) along the transverse axes (OX and OY) and applying the previously determined error correction value to the measurements so obtained.

Patent GB-2216056-A (GB)
Title: Glove boxes
Inventor: COLES TIMOTHY PAUL
IPC: B25J21/02
Filed: 1988-03-17
Abstract: Gloves used in glove boxes are fixed to the sleeves by securing a rigid flanged cuff ring on the "wrist" (or inner) end of the sleeve, and mounting the glove on this. During replacement of an old glove by a new glove the flange makes it hard to remove the old glove, especially when the new glove has been stretched onto the cuff ring on top. The invention proposes that the problem of easily removing the glove (21) from the flange (32i) be solved by giving the flange (32i) at the ring tube's (22) inner end a flat (34). Though the rest of the flange holds the glove firmly in place during normal use, during replacement a glove (21) will, clearly, slide off the ring (22) more easily at this flat (34) than wherever there is a flange (32i). A similar connecting ring is provided to connect the outer end of the sleeve to a flexible glove box wall. <IMAGE>

Title: Evaluation of an extremum of binary encoded words
Inventor: CULVERHOUSE PHILIP FREDERICK
IPC: G06F7/02
Filed: 1989-05-31
Abstract: The maximum and/or minimum of a data word set are evaluated by tag propagation through a number of iterations equal to the number of bits per word. Iterations may be performed serially using a series of logic stages 1, as shown, or cyclically using a single stage (Fig 1). For evaluation of the maximum, a respective tag is propagated for each word for which a tag has already been propagated from the previous iteration and either the word bit having a significance respectively associated with that iteration is of logic value 1 or if not 1 the word bit for each and every word for that iteration is 0. A tag will be propagated throughout all iterations only for the maximum and this tag is then used to select the corresponding word that is the maximum. The iterations may be performed for the inverse of each word bit to evaluate the minimum. In this case a tag is propagated for each word for which a tag has been propagated from the previous iteration and either the word bit represented is 0 or if not 0 then the word bits for that iteration are all 1. …<??>Implementations are disclosed for both ordinary logic Active HIGH, and for inverted logic, Active LOW. …<??>The electronic devices used may be combined in parallel and in series to allow evaluation of larger word sets. …<IMAGE>…
