Title: An automatic clutch with crawl control for a motor vehicle
Inventor: KREMMLING BURKARD
IPC: F16D48/02
Filed: 1994-08-01
Abstract: A controller for an automatic clutch comprises a control unit which engages the clutch to transmit a torque, calculated by a crawl regulator, which propels a vehicle at a crawl speed, when the engine 7 is running, a gear is engaged and an accelerator is not being operated, ie the vehicle is either stationary or nearly stationary. The crawl regulator calculates the torque in dependence on engine speed, gearbox speed and a time-dependent torque slope programmed into memory 12 which also stores values corresponding to the disengaged position of the clutch which are used to uncouple the clutch when, for example, the brakes are operated. In all other aspects the clutch operates, by way of a hydraulic system fig 1, in a typical manner with regard to gear changing, starting and stopping etc. Fluid volume expansion, eg due to temperature, between receiver cylinder 2 and transducer cylinder 16 is compensated by bore 25 so that the clutch position measured by potentiometer 18 is the same as the actual clutch position. Also disclosed are software and hardware emergency circuits. <IMAGE>

Title: Compensation for temperature drift and input offset in differential amplifiers
Inventor: BLOMLEY PETER FRED
IPC: H03F3/45
Filed: 1994-08-16
Abstract: The operation of a signal processing apparatus, such as an amplifier or an analogue to digital signal converter (ADC), is enhanced by connecting a preliminary amplifier 12 upstream of an amplification stage 1 of the apparatus so as to receive the same input signal as a first input of the amplification stage and to provide, an output signal which is combined with a feedback signal derived via at least a resistive path from the output of the amplification stage (either directly or, for an ADC through a clocked flip-flop and an integrating capacitor), the combined signal being fed to a second input of the amplifier stage. The arrangement compensates errors arising from eg. temperature drift, input offset voltage or current. <IMAGE>

Filed: 1996-08-15
Abstract: A process for the purification of gaseous effluents containing nitrogen oxides or nitrous vapours by washing said gaseous effluents with an aqueous solution containing hydroxyl ammonium nitrate which may be optionally O- or N- substituted by alkyl groups. The treated gases, apart from the nitrous vapours, also contain iodine, particularly iodine 129 and are in particular constituted by so-called "dissolving" gases formed during the dissolving of the irradiated fuel in reprocessing plants.

Title: I.c. engine common rail fuel injection valve
Inventor: AUGUSTIN ULRICH
IPC: F02M61/20
Filed: 1997-08-18
Abstract: The injection valve has a nozzle housing 1 with an inlet passage 2 connected to a high pressure common rail; a branch passage 2a is connected to a control space 4. The pressure in the control space 4 acts on a control piston 3 which exerts force on the rear end of the nozzle needle shank 10. The control space is also connectible to a pressure relief line 8 by the opening of a pressure relief valve 7 actuated by electromagnet 9. The control piston 3 has a bore 16 enclosing a closing spring 17. If there is pressure in the inlet 2,2a, the control piston and the nozzle needle shank 10 contact each other directly so that the closing spring 17 is bypassed; the closing spring 17 comes into action only when the system is at rest, the service life of the spring 17 is thus extended. In modifications (figs.2,3) the spring is guided by a pin (fig.2) or a sleeve (fig.3) which acts as a spacer between the control piston 3 and the nozzle needle shank 10.

Title: Method for forming a casing window
Inventor: OWEN HARROLD D
IPC: E21B23/00
Filed: 1997-08-08
Abstract: The method and apparatus of the present invention allow the creation of a window in casing downhole using explosive techniques. Locating stakes (10) are initially placed and subsequently surveyed for their depth and orientation. The window-cutting tool locates itself on one of the stakes, and the explosive charges are oriented with respect to the lug downhole so that when the tool is fired, the cuts are made with the appropriate orientation at the proper depth. In the preferred embodiment, horizontal cuts are made, followed by vertical cuts. The tool has the capability of positioning itself adjacent the casing which is to be explosively cut. The strips that are created after the horizontal and vertical cuts are concluded are fished out using a variety of alternative techniques. Another locating or orienting lug, which has been initially installed, can subsequently be used to locate and orient an anchoring device for a whipstock so that the sloping face of the whipstock is pointed directly at the window that has just been explosively cut.

Title: Installation of a foundation pile in a subsurface soil
Inventor: CHEN JEN-HWA
IPC: E02D7/02
Filed: 1998-03-20
Abstract: A method of installing a tubular member in a porous, solid medium beneath the surface of a body of water (12) comprises placing an open-ended member (10) in an upright position with an open end (14) positioned upon the solid medium (22), allowing water to pass into the interior chamber (20) of the member through the open end (14), pumping out a given amount of water to reduce the water level below that of the water surrounding the tubular member and driving the tubular member into the solid medium. The tubular member comprises a first end (14), a second end (16) and an interior chamber (20) bounded by a connective wall (18). Both the first and second ends are open and in fluid communication with the interior chamber. Pumping water out of the tubular member via a discharge line (34) and outlet port (38) reduces the resistance from the plug (32) as the member is driven downwards by, for example, an impact hammer. As the member is driven downwards, additional water can pass upwardly into the interior chamber from the soil medium.This too can be pumped away.
