Title: Igniting device for a gas generator
Inventor: CAFLISCH ERWIN
IPC: B60R21/26
Filed: 1994-08-19
Abstract: An electrical igniter for a gas generating device for a vehicle air bag or belt tensioner comprises contact pins (8) connected by an igniting element (7). The pins (8) pass through a bore (12a) of a galvanically conductive ring (12) having a defined spacing (ê) from contact pins (8) and forming a reliable voltage surge protection with the earth (E). The igniting element (7), constructed as a glow wire, is located in a first detonator layer (5), which is pressed together with a second detonator layer (6). The second layer (6) is less highly explosive than the first layer (5) and has a pulse-reducing effect on the detonating pressure surge for expanding the air bag or for actuating the plunger in the belt tensioning means. <IMAGE>

Title: Rough grinding of cam within two rotations of workpiece relative to grinding wheel by sychronisation of cam rotation with wheel infeed/outfeed
Inventor: BARTLETT CHRISTOPHER DAVID
IPC: B24B19/12
Filed: 1995-01-25
Abstract: A method and apparatus for grinding a cam (12) with a cam lobe is provided. Rotation of the cam (12) is synchronised with the infeed/outfeed movement of a grinding wheel (10). Control means measures the relative rotational and lateral positions of the cam (12) and grinding wheel (10). The movement of the grinding wheel (10) relative to the cam (12) is controlled to roughly grind a desired cam profile. Finish Grinding may be by way of grinding wheels or abrasive belt. Surface hardening may be applied to the ground cam before the finish grinding step. Rotation of the cam and operation of the cam/grinding wheel infeed/outfeed are synchronised so that the grinding wheel 10 first contacts the workpiece eg. a camshaft 12 ahead of the peak 14 of the cam lobe and as infeed continues the radius of the peak is attained at the intended position of the peak as it becomes aligned with the grinding wheel with rotation of the workpiece, and the wheel breaks contact with the ground face of the cam at or after the peak becomes aligned with the wheel for a second time but before the third such alignment. A grinding machine for carrying out the method comprises first position sensor to determine the distance between the longitudinal axis of the workpiece and the nearest point thereto on the surface of the grinding wheel, second position sensor to determine the angular position of the rotating workpiece, and a control responsive to signals from the sensors to control the infeed/outfeed drive. Finish grinding may be by grinding wheel or abrasive belt. Before finish grinding the ground cam may be surface hardened. <IMAGE>

Title: Method of and apparatus for determining a rotor displacement parameter
Inventor: ACARNLEY PAUL PHILIP
IPC: H02P6/18
Filed: 1993-08-11
Abstract: The invention relates to a motor monitoring and control circuit in which a value parameter is calculated for a position of the motor at given instants. The same parameter (which may be position or speed of a rotor) is then measured at subsequent instants. These values are used to compute a future value of the parameter. The advantage of the invention is that it can be used for any type of motor and that it can be easily and quickly fitted to a motor without the need for expensive and time consuming initial measurements and computation of characteristic properties of the motor in order to calibrate it. Similarly automatic compensation is made during operation. <IMAGE>

Title: Method of recycling a discarded polyurethane foam article
Inventor: CHANG CHING-BING
IPC: C08J11/06
Filed: 1995-04-20
Abstract: A method of recycling discarded PU foam articles comprises a first step of grinding the discarded PU foam articles 10 into fine particles 13, which are then mixed with a predetermined amount of a powdered plastic 14 (polyamide or polyester) in a container 16 to form a mixture. The mixture is then heated in a container 18 to produce a molten mixture which is cooled to take form. The molten mixture may be adhered to the surface of a cloth or leather material 26 when the cooling and forming processes of the molten mixture are under way. The final product can be burned at a high temperature to produce a high-carbon residue, which is added to the mixture to make a product having deodorant and antistatic properties.

Title: Wet type exhaust gas desulfurization apparatus and method utilizing solid desulfurizing agent
Inventor: KIKKAWA HIROFUMI
IPC: B01D53/50
Filed: 1995-05-11
Abstract: A wet type exhaust gas desulfurization method wherein an exhaust gas discharged from a combustion apparatus, such as a boiler and an absorption liquid are brought into contact with each other to have sulfur oxide in the exhaust gas absorbed in the absorption liquid and neutralize the sulfur oxide-absorbed absorption liquid, characterized in that lime stones of a large grain size are allowed to stay selectively in a position in which the absorption liquid is neutralized, the absorption liquid which contains as main components gypsum produced from the sulfur oxide and water being discharged selectively from the neutralization position. In the neutralization position, an ascending current of the absorption liquid is formed, or an ascending current of air or water is formed with or separately from the ascending current of the absorption liquid, to produce a fluidized bed of lime stone particles, whereby the reactivity of the lime stone is maintained with the scaling of gypsum particles around the lime stones prevented. Thus, even when aluminum and fluorocomponents coexist in the absorption liquid, the desulfurization performance does not substantially lower. Moreover, the cost of power for pulverizing the lime stones can be reduced, and high desulfurizing performance can be attained. A wet-type flue gas desulfurization method and plant making use of a solid desulfurizing agent in which exhaust gas exhausted from a combustion equipment such as boilers is brought into contact with absorbing liquid to absorb sulfur oxide from the exhaust gas to the absorbing liquid followed by neutralization of the absorbing liquid containing the sulfur oxide thus absorbed, which comprises selectively leaving the solid desulfurizing agent in an absorbing liquid neutralizing zone and selectively draining the absorbing liquid containing water as a main constituent and solid products formed by the sulfur oxide from said neutralizing zone. In the neutralizing zone, an upward flow of the absorbing liquid is generated or, together with said upward flow or independently therefrom, an upward flow of air or water to form a fluidized bed of limestone particles, thereby preventing scaling of gypsum particles around limestone and keeping reactivity of limestone. According to the present invention, coexistence of Al and F in the absorbing liquid seldom deteriorates the desulfurizing performance. Further, it is possible to reduce a power cost required to grind limestone and to achieve higher desulfurizing performance. <IMAGE>

Title: Control of a gear change of a stepped-ratio automatic gearbox of a motor vehicle
Inventor: TIETZE FRANK
IPC: F16H59/38
Filed: 1996-03-29
Abstract: In a method for the control of a gear change of an automatic stepped-ratio gearbox of a motor vehicle, in which one frictional connection is disengaged as another is engaged, the change in the gearbox input rotational speed during the shift is controlled by control of the transmission torque of a frictional connection in response to a required deceleration value as a function of deceleration torque. This control further utilises measurements of the gearbox input torque (calculated from engine torque and toque converter characteristics) and of the torque resulting from the change in moment of inertia of rotating masses during the shift.

Filed: 1997-05-01
Abstract: Side track cutting apparatus includes a mill 32 having a tapered end which engages an initial ramp on the guiding surface of a whipstock. The angle of the starter ramp 45 is parallel to the tapered cutting end of the mill.
