Abstract: Method and apparatus for effecting operations, such as punching holes in sheets of material at precise locations thereon. Each sheet has a reference marking thereon and is placed on a receiver one by one and is held in fixed position on the receiver. A T.V. camera views each sheet to detect the reference marking thereon and a visual display of the marking is produced on a T.V. monitor. Also produced on the monitor is a cross-hair grating with a coincident shaded box. The cross-hair grating is first aligned with a marking reference on a master sheet to establish a fixed relation between the cross-hair and the marking reference on the master sheet and thereby between the cross-hair and the operating system, for example, the punches for punching holes in the sheets. The master sheet is removed and the sheets to be punched are placed one by one on the receiver which is moved to align the reference marking on each sheet, as viewed on the monitor with the cross-hair grating thereon.

Abstract: An antilock braking system and associated method for a four wheel automotive vehicle having front left and right wheels and rear left and right wheels with a determined weight distribution of the vehicle on the front and rear wheels, each wheel having a respective brake cylinder adapted for applying braking pressure to the wheel in response to pressure fluid supplied from a master cylinder. The supply of pressure fluid from the master cylinder to the brake cylinders during a braking operation is controlled in accordance with the weight distribution of the vehicle on the wheels to enable the front and rear wheels normally to undergo incipient wheel slip at substantially the same time. A fluid pressure regulating unit relieves the fluid pressure transmitted to the respective brake cylinders of the four wheels of the vehicle all at the same time when one of the two front wheels rotates at a higher circumferential speed than the other front wheel and indicates incipient wheel slip.

Abstract: Apparatus for preventing undesirable reduction in the speed of an engine after starting and including an actuator operable upon engine starting to correct throttle opening to a determined extent in increasing direction, a vacuum power system for the actuator and a switching control circuit for detecting engine starting and predetermined running states of the vehicle and engine to keep the actuator energized as long as the engine speed and the vehicle speed are both below respective preset level. Even after the preset level of vehicle speed has been exceeded, the actuator is also energized in the presence of battery load, such as air conditioning or headlights when the engine speed remains below its preset level. The actuator is de-energized when the vehicle speed exceeds its preset level in the absence of battery load as well as when the preset level of engine speed is exceeded.

Abstract: The number of blow mold stations being associated with a blow wheel of a blow molding machine determines a large pitch of the mandrel receiving positions of the blow wheel. Contrarily the mandrels carrying the parisons are disposed very close to each other on the heating wheel which thus has a substantially smaller pitch. The larger pitch of the blow wheel shall be maintained throughout the complete machine to simplify the transfer of the parison. Accordingly the heating wheel receives the same pitch as the blow wheel including additional mandrel receiving positions which are served in a plurality of subsequent revolutions of the heating wheel.
