Title: Method of regulation of the duration of repeated rectangular electric signal and devices for the practical application of the same method
IPC: F02B1/04
Filed: 1968-11-20
Abstract: Method and apparatus are disclosed for varying the width of a rectangular pulse which controls the opening of an electromagnetic fuel injector, in accordance with engine speed. Reference pulses of short duration are generated in synchronism with engine rotation and these pulses are utilized to generate injection pulses, and control pulses. The termination of the control pulse, which is of predetermined width, is utilized to generate a linearly increasing reference voltage which reaches a predetermined voltage level, depending on the spacing between the preceding reference pulse and the following reference pulse. The voltage level reached by the reference voltage is utilized to cut off the injection pulse. The width of the injection pulse, and in consequence the quantity of fuel injected, is thus directly controlled by engine speed, i.e., by the spacing of the reference pulses.

Title: Apparatus for moving cutters in machines for shaving metallic rod stock
IPC: B23B5/12
Filed: 1973-04-26
Abstract: A machine for shaving metallic rod stock has two spaced-apart sets of advancing rolls which transport a workpiece lengthwise and are driven by discrete motors so that the movements of one set of rolls are synchronized with movements of the other set of rolls. A rotary sleeve-like tool holder surrounds with clearance the workpiece between the two sets of advancing rolls and carries several radially extending cutters which are movable radially into and form engagement with the workpiece by an adjusting unit including a variable-speed transmission driven by a further motor. When the motors for the advancing rolls are arrested, the rolls continue to advance the workpiece for a certain interval of time due to inertia. In order to make sure that the cutters are disengaged from the workpiece only when the lengthwise movement of workpiece is terminated, the motor for the adjusting unit is started with a certain delay following stoppage of the motors for the advancing rolls, whereby the length of such delay corresponds to the interval of lengthwise transport of the workpiece due to inertia of the rolls. The motor which operates the adjusting unit is started prior to starting of the motors for the advancing rolls so that the workpiece is set in motion simultaneously with termination of movement of cutters from retracted to operative positions.

Patent ES-442541-A1 (ES)
Title: Use of tankers as fermenting vats
IPC: C12M1/00
Filed: 1975-11-12
Abstract: Many tankers can lie idle for longer or shorter periods or can travel empty from oil consumers on the way back to the oil suppliers. The present invention is related to utilizing vessels, which for longer or shorter periods and for various reasons cannot travel with a full load, as fermenting vats for, for example, alcohol fermentation. Water supply and temperature control are easily taken care of by means of water from the surrounding sea, and disposal of the waste from fermentation can also be accomplished by direct release, since the residues from the fermentation comprise organic material which decomposes in a very short time. In this way fermentable waste, e.g. sugar cane molasses, can be loaded for example in Cuba and allowed to ferment on the way to Europe where it is directly unloaded as finished alcohol or as raw material for a distillation plant.
