Title: Crop thinning machine
IPC: A01B41/06
Filed: 1967-12-11
Abstract: In a crop-thinning machine (see Division A1) a probe 258 completes a circuit whenever it contacts a plant to turn on transistors Q 1 , Q 2 and provide an output on line 411 which is fed to a dead-time unit 420, comprising monostable circuit Q 3 , Q 4 , the dead-time being determined by resistors R T and switch S. The signal on 411 switches the monostable circuit to its unstable state, to provide a feedback signal on line 421 which inhibits further actuation of circuit 410 during the dead-time. At the same time an output on line 412 switches bi-stable circuit 440 to energize the trigger circuit 450, thus firing triac Q 9 to energize a solenoid valve.

Patent ES-440682-A1 (ES)
Title: Delayed bolt action for firearm
IPC: F41A19/06
Filed: 1975-09-03
Abstract: A delayed blow back bolt action for a firearm includes a bolt and a slide which are movable together in the receiver frame and are disposed for limited movement with respect to one another. The bolt and slide have cooperating camming surfaces which cause a relatively large displacement of the slide in relation to the displacement of the bolt when the forces attendant to the discharge of a round in the firearm are initially applied to the bolt. The bolt is provided with a lug which engages a locking recess in the receiver frame of the firearm, and the lug and recess have cooperating camming surfaces, such that a surface of the recess provides an opposing force to the force generated by the discharge of a round from the firearm, which force is exerted against one end of the bolt. As such a force is supplied to the end of the bolt, the locking lug is forced out of the locking recess, thereby camming the slide in a direction which is along the longitudinal axis of the bolt. The delay caused by such camming action and movement of the slide is sufficient to permit the discharge of a round from the barrel of the firearm and substantial dissipation of the resulting gases. The moment of the moving bolt and slide, after the locking lug is removed from the locking recess, is sufficient to force the bolt and slide to a rearward position to open the breach, thereby cocking the hammer and permitting a second round of ammunition to be chambered.

Patent ES-444140-A1 (ES)
Title: Doubly-compensated dual-detector density logging apparatus
IPC: G01V5/12
Filed: 1976-01-08
Abstract: A technique for determining the density of an earth formation with a logging sonde including a gamma ray source and two gamma ray detectors spaced at different distances from the source is disclosed. The count rate of the short-spaced detector is measured in two energy ranges covering back-scattered gamma rays which have undergone relatively low and high attenuations respectively. A first density correction is determined from the difference between the apparent density derived from the count rate of the long-spaced detector and the density derived from the count rate of the short-spaced detector in the energy range covering gamma rays with relatively low attenuation. A second density correction is determined from the difference between the densities derived from the two short-spaced detectors' count rates. These two density corrections are added to the apparent density to give the true formation density.
