Patent ES-299667-A1 (ES)
Title: Razor-blades
IPC: B26B21/60
Filed: 1964-05-09
Abstract: The cutting edge of a razor blade is coated with a substantially monomolecular layer of a compound possessing a hydrophobic group and at least one polar group. The compound may be a fatty acid, a salt thereof an amine, amide, alcohol or ketone, a phosphate, phosphonate, sulphate or sulphonate. The compound may be applied in the molten state by dipping or spraying or in solution by dipping or by floating a solution of the compound on water and passing the blade therethrough, or by electro-de-position for example from a bath of an alkali metal soap using a voltage of 10 volts and a current of from 200-500 milliamperes, piles of blades being arranged as anodes between two coaxial cylindrical stainless steel cathodes. When the compound is a fatty acid or derivative thereof or a phosphate, phosphonate, sulphate or sulphonate it is said to bond itself to the surface by chemical reaction, forming a metal soap with the metal surface. The remaining compounds are said to be bonded to the blade by adhesion forces. In examples, stearic acid, sodium stearate and octadecyl phosphonate are referred to.ALSO:The cutting edge of a razor blade is coated with a substantially monomolecular layer of a compound possessing a hydrophobic group and at least one polar group.

Patent ES-407937-A1 (ES)
Title: A spring actuated device for projecting clay pigeons
IPC: F41J9/18
Filed: 1972-10-25
Abstract: An apparatus for the tossing of disc-shaped objects, the so-called clay pigeons including a main frame carrying a main shaft and an ejector arm. A crank arm is mounted on the frame and driven by an ejector spring. A motor drives a worm gear and worm wheel and a double coupling means comprising a one-sided overrunning clutch to allow the shaft to overrun the motor drive and a releasable clutch interposed between and interconnecting the worm wheel and the main shaft to release the shaft from the worm wheel when the crank arm is in its dead center position and the spring fully tensioned. A trigger locks and releases the releasable clutch in the position in which the ejector spring is fully tensioned and the crank arm is in its dead center position. An actuator reacts with the trigger to release the releasable clutch whereupon the motor drives the main shaft via the worm gear and the worm wheel through the one-sided overrunning clutch and the crank arm is driven off its dead center position. After a short rotary motion, the ejector spring via the one-sided overrunning clutch produces the additional speed necessary to launch a clay pigeon from the ejector arm without jerking the throwing arm. The pigeons are caused to be moved to the ejector arm by actuation of a cam follower connected to an elevator. The elevator carries the pigeons one at a time, from a stack, to the ejector arm. While the elevator is carrying a pigeon to the ejector arm a cam operated member is caused to move into engagement with the remaining stack of pigeons so as to support the remaining stack of pigeons.

The sampled functions are stored electronically and also visibly presented on a retentive CRT display unit associated with the computer system. A keyboard associated with the computer permits a service operator to interact with the program and select the service processor which is to be monitored and the time measurement parameters of the system with selection prompting indications presented by the program to the operator via the display unit. An example is given of the time-referenced indication of feeding, punching, reading, printing and stacking functions of a record card processing unit.

Title: Auxiliary ring rail positioning means for textile twister or like machine
IPC: D01H13/24
Filed: 1974-05-08
Abstract: In immediate response to the detection by a yardage counter or the like of a full package condition at the textile machine, the auxiliary ring rail positioning means rapidly moves each ring rail of the machine directly and unidirectionally, from whatever random vertical position it might then occupy, to a preselected doffing position preferably located between and in spaced relation to the opposite ends of the normal path of reciprocatory movement of the ring rail. Upon each subsequently ensuing start-up of the machine, the auxiliary ring rail positioning means rapidly reciprocates each ring rail, between the aforesaid preselected doffing position and the lower limit of the rail's normal path of reciprocatory movement, for an adjustably variable time period sufficient to "tie-in" the yarn ends.
