A multi-battery charging system for reduced fuel consumption and emissions for an automotive vehicle. The system starts the vehicle with a start battery in a fuel savings manner, removing electrical torque from the alternator shaft, and allows a second (run) battery to provide all or some of the current required by the vehicle loads as a fuel savings measure. The system also utilizes an electrically heated catalytic converter (EHC) and a third (EHC or storage) battery to provide a 3 to 15 second preheat and / or a 20 second current, during vehicle start, to the EHC heater coil, e.g., of a small EHC located in series with a standard catalytic converter for emissions reduction to reduce emissions during start. The start battery is recharged after start and switched out of the system fully charged for future vehicle starts. The run battery is recharged when its charge level drops below a predetermined level with an on board battery charging device powered from a 115 volt or 220 volt ac power line source external to the vehicle.

An adjustable safety utility knife includes a elongated ergonomically shaped handle formed of two elongate shell members each having a peripheral edge and an outer, generally convex surface and an inner generally concave surface. A fastener secures the shell members together at their peripheral edges along a parting plane to form an elongated internal cavity. The handle defines a front end, back end and an intermediate portion suitable for being gripped by a user and also defines top and bottom surfaces extending along opposite sides of the shell members along the peripheral edges. The handle has a slot-like aperture at the front end substantially aligned with the parting plane and dimensioned for passage of a flat cutting blade therethrough. The cutting blade is mounted for movement by a suitable guide member or a carriage between a first position for safely storing the blade fully inside the cavity and a second position for selectively extending the blade beyond the aperture to expose at least a portion thereof. A manually operated button is arranged on the top surface of the handle and is coupled to guide element or blade carriage for selectively moving the blade between the first and second positions. Slip resistant elements are secured to the shell members along the top and bottom surface between a rearwardmost operative position of the manually operated button and the back end of the handle. The slip resistant elements generally conform to the outer convex surface of the handle and enhance gripping of the handle and minimize slippage thereof during use of the utility knife when gripped by a user.

An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450% greater than its initial, pre-stretched length. The increased contact between the large diameter heated rolls and the film and the short draw gap between the two heated rolls result in a highly stretched film having minimal neck-in.

The invention provides for operation of camshafts, particularly for an injection pump for diesel. A camshaft rotates around a longitudinal axis of a camshaft. The camshaft has at least one cam being in cooperation with a pressure roller driven in a lifting manner. The pressure roller rotates on the peripheral surface of the cam. The upward stroke of the pressure roller is a working stroke during which the pressure roller moves away from the longitudinal axis of the camshaft. During a return stroke the pressure roller moves toward the longitudinal axis of the camshaft. The peripheral surface of the cam has a return stroke section and a working stroke section. The peripheral surface of the return stoke section has a greater friction value than the working stroke section. Thus an operation of camshafts for an injection pump for diesel is provided, securing a rotation of the pressure roller around the circumference of the cam within the whole speed range of the camshaft.

In various embodiments of the invention, a system and dynamic device are provided to create stability of tube placement in medical and other applications. The described systems and principles also apply in other environments outside of medicine and healthcare. The described medical tubing stabilizer adheres to the tubing itself providing handles or anchors to prevent stitch slippage and to prevent the tubing from falling out in any situation that requires a semi or permanent tubing placement. The device also aides in stabilizing the tubing in the wound site, and thus maximizes placement in its intended area of effect (e.g., in the body cavity, in a medical context). These stabilizing effects substantially minimize slippage of stitching holding the tubing in place to prevent the tubing from falling out or becoming dislodged or displace, thus preventing irritation and damage to the skin around the wound site, infection, seroma, edema and morbidity in a medical context.

A transmission that functions as a combination friction drive and gear tooth drive: The transmission utilizes VCT conic teeth added to the surface of a variable pulley. The teeth in the sides of a continuous loop, or a two-faced gear, engage the teeth on this conic surface. When the pulleys contract or expand, the top of the teeth engage the surface frictionally. When the contraction or expansion of the pulleys move the continuous loop, or two-faced gear, to the next ring of conic teeth, it engages the conic teeth as a toothed drive.
