Title: Methods and apparatus for well investigation and development
Inventor: BRYAN EDWARD L
IPC: G01N21/17
Filed: 1982-01-15
Abstract: A system for analyzing geological materials in and from a borehole includes apparatus (87, 89) for extracting and separating chips and grains from drill mud return by size, preparing (100-116) the material for examination and optically examining the material using fiber optic devices (121). The images thus derived are optically (22) and digitally processed (21, 23) and classified by numerous chemical, lithological and paleontoligical criteria using a geological data base (20) which is updated. Data from this analysis forms a basis for predicting hydrocarbon location and detecting its presence. An apparatus (165) for directly viewing a borehole wall in situ is disclosed, the apparatus using fiber optics (182, 183) to provide images at the surface which can be similarly analyzed.

Title: Method of and apparatus for cleaving optical fibres
Inventor: FELLOWS ANDREW THOMAS
IPC: G02B6/25
Filed: 1984-01-05
Abstract: A method of cleaving an optical fibre 5 to produce optically flat ends orientated to within a degree of a radial plane of the fibre (and therefore suitable for subsequently forming a low-loss fused joint) comprises the steps of tensioning the fibre over a supporting surface 6, radially applying a lightly loaded cutter 10 moving under low momentum to the fibre surface and subsequently increasing the load on the cutter to apply a correspondingly increasing radial pressure to the tensioned fibre until it cleaves. In a tool for carrying out the method the cutter 10 is carried by a tube 7 partially filled with liquid 8 which is approximately balanced about a horizontal axis 2. In use the tube is tilted through the horizontal with the cutter a few mm above the fibre surface. Consequently a bubble 12 travels along the tube and the tube/cutter gently and reproducibly topples onto the fibre and applies a gradually increasing radial pressure to the fibre until it cleaves. <IMAGE>

Title: Auxiliary brake device of automobile
Inventor: FANN JONG-YEUAN
IPC: B60T1/06
Filed: 1986-10-02
Abstract: An auxiliary brake device 35 of an automobile is located in the transmission line ahead of the differential 36. The device has an input shaft 1 connected with the automobile engine 31 and an output shaft 3 connected with the differential. A pulley 11 on the input shaft is connected via a belt 12 with a further pulley 10, and pulley 10 is connected via an electromagnetic clutch 9 and electromagnetic brake 8 to a spur gear 5. The clutch and brake are normally demagnetised such that spur gear 5 cannot rotate and the input shaft 1 and output shaft 3 rotate at the same speed. When the brake device is to be made operative a switch is closed actuating the clutch to provide drive between pulley 10 and spur gear 5 and to take off brake 8. The input shaft 1 will then rotate at a greater speed than output shaft 3 causing engine braking of the automobile since it is assured that the automobile will during braking be driven by its inertia. The belt and pulleys may be replaced by a friction drive. <IMAGE>
