Patent GB-2225822-A (GB)
Title: Transmission
Inventor: PARSONS DAVID
IPC: F16D48/06
Filed: 1990-01-08
Abstract: A motor vehicle has at least one ground running wheel driven by an internal combustion engine (10) via a transmission comprising a clutch (14) and a change-speed gearbox (12). Gearbox (12) has a plurality of mutually exclusively engageable gear ratios any desired one of which can be engaged by pivoting gear lever (16) manually, in direction (A) or (B) accordingly, about pivot (34) so that part of the gear lever (16) above the pivot (34) moves from one side of the gear shift pattern to the other side. Gear lever (16) comprises shaft (32) pivoted at (34) and a hand knob (42) on a tube (40) rockably pivoted at (44) on the shaft (32). When the tube (40) is rocked by manual force in direction (a) or (b) relatively to shaft (32) a signal is sent on line (64) or (66) to clutch control (18, 20) causing automatic dis-engagement of the clutch (14). Continued application of the manual force on the tube (40) causes the latter to push the shaft (32) which pivots in direction (A) or (B) to the opposite side of the gear shift pattern. On control (18, 20) receiving a signal on line (54) that a new gear ratio has been engaged, the control (18, 20) automatically re-engages the clutch (14). Springs (46) act to hold the tube (40) in a central or initial position relative to shaft (32) when no manual force is applied to knob (42). The clutch control (18, 20) includes an initiating device (68) which observes when the new gear ratio has been engaged and prevents a subsequent dis-engagement of the clutch (14) until the tube (40) has first been allowed to return to the initial position relative to the shaft (32).

Title: Estimating the condition of buried sedimentary material
Inventor: SCOTT DAVID RUSSELL
IPC: G01V1/28
Filed: 1991-03-19
Abstract: Methods of geophysical exploration are provided for estimating the burial conditions of sedimentary material in a selected basin. The burial conditions can include measures of porosity, lithology, pore fluid pressure, effective pressure, and density. In particular, a reference velocity profile is developed for a model of the sedimentary material comprising the basin and is compared to a velocity profile obtained from seismic data to obtain estimates of the burial conditions of the sedimentary material. Data obtained at the surface and within a borehole is used.

Title: Compact zoom lens system capable of high zoom ratio and having coverage of a wide visual field
Inventor: ITO TAKAYUKI
IPC: G02B15/173
Filed: 1991-10-15
Abstract: As shown in Figure 1, a zoom lens system with a macro system has three groups of lenses, namely, in order from the object side, a first group having a positive focal length, a second group having a negative focal length and a third group having a positive focal length. When zooming is effected from wide-angle to telephoto the distance between the first and second groups is increased and that between the second and third groups is decreased, all three groups being moved towards the object. The third group is divided into a positive focal length unit 3a and a negative focal length unit 3b, these units being moved independently when zooming from wide angle to telephoto so that the distance between them increases when zooming from wide-angle to an intermediate focal length, but decreases when zooming from the intermediate focal length to telephoto. Normal focusing is achieved by moving the first lens group, but close-up focusing is achieved by fixing the first group at the telephoto position, and moving the second lens group towards the object while one or both of the lens units 3a, 3b is or are moved to increase simultaneously the distance between the second lens group and the lens unit 3a and the distance between the lens units 3a and 3b. <IMAGE>

Title: Stand
Inventor: ARBITER IVOR DAVID
IPC: F16M11/00
Filed: 1991-11-05
Abstract: A stand suitable for supporting a musical instrument keyboard includes a pair of elongate legs 1, 2, joined at a pivotal joint roughly midway along their length. Each of the logs has transversely extending feet 4, 5 at one end and transversely extending support members 7, 8 at the other end. In use, a keyboard, or a platform for a keyboard, rests on the support members. The pivotal joint is designed so that when it is free one leg can move pivotally with respect to the other through substantially 180 DEG . When the pivotal joint is engaged it holds the leg members fixed with respect to each other at any desired angular position. In a preferred example, the stand further comprises a platform 20 which rests on the support members with the depending outer edges of the platform engaging the outer edges of the support members. The platform also then serves to provide further bracing for the stand. A retractable spur 9 may be provided on each foot to adjust, in use, the keyboard angle. <IMAGE>

Title: Consumable electrode dc arc welder
Inventor: MORIGUCHI HARUO
IPC: G05F1/08
Filed: 1992-10-30
Abstract: A consumable electrode DC arc welder rectifies an AC input 1, converts it to a high frequency AC using an inverter 4, and rectifies it again 7 to provide a DC supply to the load 11. The output voltage V is stabilised by comparing it to a reference voltage Sr and using the output to control the inverter. The output voltage is also used to detect arcing and shorting, and responds to these by increasing 30 or decreasing 24 the reference voltage. This prevents spattering. <IMAGE>

Title: Directional drilling method and apparatus
Inventor: SHEPPARD MICHAEL CHARLES
IPC: E21B7/18
Filed: 1993-12-17
Abstract: A method for causing deviation of borehole being drilled by rotary drilling uses a bit having at least one nozzle 42 through which a drilling fluid is caused to flow such that in use, the flow of drilling fluid through the nozzle allows one sector of the bit to cut more effectively than the remainder of the bit, the method comprising modulating the flow of the drilling fluid through the nozzle such that the cutting action of the one sector is optimised when in the desired direction of deviation and such that the cutting action of the one sector is reduced at other locations in the borehole as the bit rotates. Apparatus for controlling the direction of drilling of a borehole comprises a rotary drill bit having at least one nozzle for a drilling fluid to flow therethrough, the flow of drilling fluid through the nozzle over cutting structures on the bit causing one section of the bit to have a comparatively improved cutting action with respect to the remainder of the bit; means being provided to modulate the flow of drilling fluid through the nozzle so as to modulate the cutting action of the one section such that the comparatively improved cutting action occurs in a desired direction of deviation of the hole. <IMAGE>
