Patent ES-352325-A1 (ES)
Title: Microtome
IPC: G01N1/06
Filed: 1968-04-03
Abstract: A microtone comprises a holder 30 carrying a specimen 34, a co-operable blade 22 mounted in a member 14 for movement towards and away from the holder 30 and a spring 62 which biases the blade 22 towards the specimen and also holds a bearing 54, on member 14, against a surface 40 of an adjustable cam 38, and a surface 42 of the latter against a surface 60 rigid with the holder 30, the position of cam 38 determining the thickness of the slice. As shown the holder 30 and surface 60 are provided on a shaft 28 so that when the latter is rotated, either manually, or by means of a motor driven shaft 88, the specimen 34 is rotated into contact with the blade 22 and a gear train 68, 70, 72 is set in motion. Gear 72 is rigid with a five-toothed gear 61 which is so arranged that it engages a gear 73 only after the specimen 34 has passed the cutting edge 23 of blade 22. The rotation of gear 73 causes a pawl carrier 76 to rotate against the action of a spring 77 carrying with it a ratchet wheel 79, which, through helical gears 78, 80 and screw 58 causes the cam 38 to slide to the left. The consequent movement of member 14 about its pivot 16 moves the blade 22 downwardly ready to cut specimen 34 again during the next rotation of shaft 28. When the five-toothed gear 61 has disengaged gear 73, the pawl carrier 76 returns to its initial position under the action of spring 77. The pawl on pawl carrier 76 may engage ratchet wheel 79 for a portion only of its total travel by varying the angular position of an opening 87 in a protruding portion 85 of an adjustment sleeve, so as to vary the amount of movement of cam 38 and thus the thickness of the slice. By positioning a microscope slide on guides 44 against an abutment 91, a finger 96 on a chain 92, driven by a gear chain from shaft 28, carries the slide over the blade to receive a slice thereon.

Patent ES-376686-A1 (ES)
Title: Subrack and rack assembly
IPC: H05K7/14
Filed: 1970-02-18
Abstract: In a rack for mounting electric circuit boards the swivelling movement of a beam 4 is controlled by an L-shaped actuating lever 15. The free end of the leg 21 of lever 15 has a buttonhole 23 through which passes a bolt 19 screwed to the end of beam 4. The free end portion of the other leg 22 is introduced in a box 18 in which a spring 17 and a stud 24 hold the leg 22 in its locked position (Fig. 3) thus holding the circuit boards in the substrate. When beam 4 is to be swivelled to its unlocked position to enable the circuit boards to be removed, or plugged-in, lever 15 is pushed down, causing leg 21 to be displaced along the axis of the buttonhole 23, and also causing a snap action movement of leg 22 into the position indicated in Fig. 4. This snap action is caused by the spring 17 pushing down onto the leg 22 when it is initially disengaged from the stud 24 by the pushing action on lever 15.

Patent ES-396086-A1 (ES)
Title: Method and apparatus for determining the quantity of a bulk material deposited on a conveyor
IPC: G01G11/00
Filed: 1971-10-16
Abstract: The weight of bulk material deposited on a conveyor is measured with reference to the force exerted by the conveyor on the material to accelerate it in the direction of transport. When the dispensed material contacts the conveyor belt, the belt applies a force to the material in the conveying direction to accelerate the material from its initial velocity to the velocity of the conveyor belt. An equal and opposite reaction force is inherently applied to the conveyor by the material as the material is deposited onto the conveyor. The reaction force is directly related to the quantity of material dispensed onto the conveyor belt since force F, acceleration a and mass m (a quantity measurement) are related by the basic equation F = ma. A suitable force measuring apparatus may be applied to detect the force or quantity measurement.
Patent ES-407969-A1 (ES)
Title: Film movement preventing means for cameras
IPC: G03B17/42
Filed: 1972-10-25
Abstract: A camera for roll film perforated at predetermined metering intervals includes a transport mechanism for advancing the film along an exposure plane and a metering mechanism having an inactive condition and an active condition for stopping film transport when the film is correctly positioned for exposure. A film sensing pawl is mounted for movement between a retracted position resting on the film surface, an extended position transversing the film while in a film perforation and a metering position spaced from the extended position in the direction of film advancement. A resilient force on the sensing member urges the sensing member from its metering position toward its extended position. Any tendency of the resilient force acting on the sensing member to move the film during exposure is opposed, at least during operation of the camera's exposure mechanism, by a member clamping the sensing member so that the force is not transmitted by the sensing member to the filmstrip.

Patent ES-439347-A1 (ES)
Title: Tension-responsive fastener drive system
IPC: B25B23/14
Filed: 1975-07-11
Abstract: A tension-responsive fastener drive system is disclosed in which tension arising in a fastener is sensed by a feeler gauge. The gauge applies a retardive force to a sensing sleeve mounted for motion with the fastener drive shaft. When fastener drive shaft-sensing sleeve motion becomes unequal, or when the sensing sleeve is angularly displaced relative to the drive shaft, a stop mechanism is actuated to halt further fastener driving action. Thus, a predetermined tension can be applied to a fastener when the fastener is driven into or secured on a workpiece.

Patent ES-444613-A1 (ES)
Title: Centrifugal compressor with indexed inducer section and pads for damping vibrations therein
IPC: F02C3/06
Filed: 1976-01-26
Abstract: A centrifugal compressor assembly for a gas turbine engine includes an inducer section and an impeller section mounted for rotation about an axis. Because leading edges of the impeller blades are cambered, damper pads, extending perpendicular to the low pressure sides thereof also extend axially forward. Blades of the inducer section are indexed rotationally rearward of the impeller blades to improve the distribution of compression gases through the impeller section and high pressure surfaces of the inducer blades mate near their leading edges with outward surfaces of the damper pads. Because the pads and inducer blades vibrate at different frequencies, inducer blade vibrations that might otherwise cause fatigue are attenuated by contact with the damper pads. The damper pad arrangement thus permits the damping of vibrations in the inducer blades notwithstanding the indexed relationship between the inducer section and the impeller section.
