Title: Controlling an auxiliary pressure pump in an anti-lock brake system
Inventor: FENNEL HELMUT
IPC: B60T8/88
Filed: 1991-03-07
Abstract: In an anti-lock brake system having an electromotively-driven hydraulic pump (32) acting as an auxiliary pressure source and switched on and off by a travel sensor (27), the drive motor (31) of the pump is also controlled by circuitry (28) in dependence on the vehicle deceleration and on the pressure fluid requirement during an anti-lock controlled braking operation, or on corresponding criteria and test results. The circuitry may determine variable "bridging times" corresponding to the deceleration and may count the number of stable phases and/or the number of pressure increase or decrease actuations of the anti-skid valves (19-24) which corresponds to the fluid requirement and may start the pump when the count exceeds a limit value within the relevant bridging time. Different control modes may apply according to the magnitude of the deceleration. <IMAGE>

Title: Tractor for towing aircraft
Inventor: MELNICK IRVING
IPC: B64F1/22
Filed: 1991-11-22
Abstract: The tractor has a main frame (104) carrying drive wheels (102), and supporting a pivotable beam (10). One end of the beam (10) carries a replaceable tool (20) for engaging an aircraft nose wheel assembly, and the other end is pivoted (12) to the frame (104). A piston and cylinder unit (14) is connected to the beam (10) and the frame (104). In use, the tool (20) engages the nose wheel assembly and then a lifting force is applied by way of the piston and cylinder unit (14) to pivot the beam (10) upwardly relative to the frame whereby a lifting force is applied to the nose wheel assembly just sufficient to lift the aircraft nose wheel assembly such that a proportion of the aircraft nose wheel weight is transferred to the driving wheels of the tractor whereby the effective weight of the tractor is increased enough to move the aircraft. <IMAGE>
Patent GB-917542-A (GB)
Abstract: 917,542. Selective punching machines. OLIVETTI & C. S.p.A., ING. C. May 5, 1959 [May 10, 1958], No. 15319/59. Class 31 (2). [Also in Group XVI] Data punching apparatus described as incorporated in the printing mechanism of Specification 783,979, comprises a coding device and a translating device relatively movable in two dimensions to select and actuate coded punches representative of a character. The coding device 30 comprises a stationary box with plates 31, 32 having locations such as holes arranged in horizontal rows and vertical columns provided with interponents such as pins 34 positionable in pre-set places according to a desired code. The translating device 35 comprises a bar 44 having operating pins 45. In operation, depression of a character key moves a corresponding slide 9 rearwards and a character lever 4 into the path of a projection 6 of a corresponding disc 7 and starts a cycle of the main shaft 18, 55. A projection 59 on the moved slide 9 rocks the bail 57 disengaging a hook 51 from a pin 50 while a cam 19 on the shaft 18 rocks a lever 17 clockwise allowing a bail 13 to follow for a set distance that is until the projection 6 contacts the moved lever 4. An arm 42 of the bail 13 rocks the translating device 35 lowering the shaft 44 to a corresponding amount. Simultaneously, the lever 17 through a link 61 allows spring 66 to move a bail 63, thus moving the translating device 35 upwards, Fig. 2, against its restoring spring 41 until a notch 60 on a lug 58 of the bail 57 is opposite the moved projection 59 when the movement is arrested and the bail 57 is restored by a spring 67 re-latching the latch 51. The translating device is thus positioned with the pins 45 opposite the row and column of the coding device corresponding to the character key depressed and a cam 54 acting through levers 52, 51 and a slide 47 actuates the bar 44 which through the pins 45 causes the pre-set coding pins 34 to actuate appropriate punch pin actuator shafts 23. The cams 19, 54 and various springs return the parts during the completion of the cycle. If two keys are simultaneously depressed the hook 51 is not released as a second moved projection 59 does not allow the bail 57 to restore for the hook to re-engage with the pins 50 to allow operation of the slide 47 by the cam 54. An auxiliary slide similar to 27 may select shaft 23 according to a code corresponding to letter spacing such a slide being disconnected upon movement of the bail 57. Specification 850,492 also is referred to.

Title: Gas turbine engine casing blade containment.
Inventor: JONES EMLYN
IPC: F01D21/04
Filed: 1992-03-26
Abstract: A gas turbine engine 10 is mounted from a pylon 26. The gas turbine engine 10 has an annular fan casing 18 which is provided with a composite containment ring 20. A plate 30 is attached to the underside of the pylon 26 the ends 32 of which extend radially inwards towards the fan casing 18. The plate 30 acts to direct the containment ring 20, as it distorts under the impact of a blade, away from the pylon 26. The plate 30 reduces the amount of interaction between the containment ring 20 and the pylon 26 so minimising any damage to the pylon and the associated aircraft structure. <IMAGE>

Title: Converting strimmers to lawnmowers
Inventor: RICHMOND RAYMOND
IPC: A01D34/416
Filed: 1994-09-09
Abstract: An attachment for a strimmer to convert it to a lawn mower comprises a single unit which has a shell 36 of a shape matching the rear of the strimmer head casing. From the shell depends a rear, hollow open sided base box 46 which has a rear ground engaging roller and side skids. When the shell is fitted snugly to the rear of the head casing the strimmer head rear guard 32 fits into the base box and the unit is attached by stretching an elasticated strap between lugs 40, 42 on the shell and over the head casing. The result is that the strimmer becomes an effective lawn mower as the roller and skids keep the cutting plane of the strimmer cable parallel to the ground. The front of the striker head is not covered so the assembly can continue to be used in normal strimmer functions. <IMAGE>

Title: Disposal of solids
Inventor: ALEXANDER ALBERT H
IPC: E21B21/06
Filed: 1995-08-21
Abstract: Methods and apparatus for the disposal of solid particulate material in subterranean formations are disclosed. The invention is not limited to the disposal of oil field waste and therefore provides means and methods for the disposal of virtually any type of waste slurry stream. A slurry is formed at the surface of the earth by mixing the solid waste in particulate form with liquid and viscosifier thereby forming a slurry. A borehole 10 is drilled into a selected injection formation 36 and the slurry is pumped from the surface through the borehole and into the injection formation. Some surface pretreating of the slurry may be required including sizing of the particulate solids adding weighting material, removing excessive amounts of oil and grease and diluting to reduce the level of radioactivity. The injection formation is preferably dipping in angle with respect to the horizontal and highly fractured. The borehole is hydraulically isolated from intervening earth strata between the surface of the earth and the injection formation. <IMAGE>
