Patent ES-345177-A1 (ES)
Title: Automatic shutter mechanism
IPC: G03B9/58
Filed: 1967-09-19
Abstract: A camera shutter comprises a blade 1 which normally covers the aperture 10, and another blade 2 which is held in the position shown by a latch 3. The latch is held against the action of a spring 11 by an electromagnet 4 energized from a battery 12. Across the battery is a resistor 14 and photo-cell 7. The battery also biases the base of a transistor 8, through which current passes to the electromagnet. Thus this current is inversely proportional to the amount of light falling on cell 7. When exposure is initiated, a member 5 swings round, breaking a switch contact 6, and so shutting off transistor 8, and hence the current to electromagnet 4. At the same time, member 5 strikes a lug on blade 1, causing it to swing aside and uncover aperture 10. The current energizing the magnet decays through a resistor 9 connected across its leads, and when this drops sufficiently, latch 3 is pulled away by spring 11. Blade 2 is thus released to swing, either under gravity or a spring, to close aperture 10 again.

Title: Device for controlling the pneumatic braking force of a railway train
IPC: B60T13/66
Filed: 1968-05-31
Abstract: Apparatus for controlling the pneumatic brakes of a train (which may have electric traction and braking) includes an Integral or Proportional Plus Integral control circuit. For a short train integral control is adequate, and the brake error signal (i.e. difference between actual and desired deceleration) is fed to an integrator circuit having a time constant such that the rate-of-change of air pressure in the train pipe is equal to or less than the rate-of-change of air pressure in any brake cylinder. In longer trains, the length of the brake pipe causes delayed rise in brake cylinder pressure and proportional + integral control is desirable, for stability, as shown diagrammatically in Fig. 4, where the braking error signal a be is applied through a limiting amplifier to an integrator 15 and through a parallel ohmic channel 16. A more detailed arrangement of this circuit is illustrated in Fig. 7 with additional features. The error signal a k is amplified at 21 to provide the proportional signal f a and also fed to limiting amplifier 23, with limit diodes 25, 26, and thence to integrator 32, and the combined signals are amplified at 38, basically as in Fig. 4. Additional features: (i) a measuring trigger circuit 40 at the output, operates at a certain minimum output to correct for small pressure drops in the train pipe (ii) for Downhill travel at Constant Speed a switching signal c from the train controller (not shown) biases diodes 29, 36, 37 to depress the limiting level of amplifier 23 and suppress the proportional signal f a -the proportional signal is replaced at the start of braking by a signal from trigger 48 (to " memory " 47 and capacitor 44) which decays in a few seconds. This signal is negligible in normal braking. Further, the switching signal c biases diodes 54, 55 to reduce the air brake signal ak by a fraction of the desired retardation a c , so that the electric brake operates on slight slopes.

Title: Device for the crystallization by heat exchange of a solute in solution in a liquor
IPC: C01F11/44
Filed: 1969-12-30
Abstract: A device for crystallization by direct contact of a solution with an inert, immiscible heat-transfer fluid comprises a crystallization enclosure 10 containing a plurality of superposed stages A, B, C. Each stage contains a fluidization chamber 11A, B, C which is closed on all sides except at its top 12A, B, C which is perforated. Heat transfer fluid is fed into the chambers and each stage has a collector 21A, B, C for the fluid whereby transfer between stages is effected. The solution is fed in at the bottom and rises through the stages, there being spaces between stages allowing this. As the solution rises crystals form and fall to the bottom for collection. As described the fluid is circulated in countercurrent to the solution via a heat exchanger 26. The chambers may be divided by partitions 14 into spaces 13. A crystal fragmenting device 48 may be provided at the top for controlling the number of crystals to be grown. Chambers 11 may be staggered relative to each other along the height of the enclosure. Crystals of Ca(NO 3 ) 2 may be so obtained from a solution resulting from the extraction of calcium salts from natural phosphate using HNO 3 the fluid may then be "white spirit".

Title: Compensating store device in systems for directly feeding cigarettes from cigarette manufacturing machine or machines to the hopper of the cigarette packeting machine
IPC: B65B19/04
Filed: 1976-01-28
Abstract: A compensating store device for cigarettes, between cigarette manufacturing machines and machines for packeting the cigarettes, wrapping the packets and making and wrapping packs of wrapped packets. The store device comprises a cylinder rotating about a vertical axis and having vertical, radial cigarette storage compartments, circumferentially distributed. A cigarette delivery channel at the top of this cylinder feeds cigarettes from a feeding conveyor run to the compartments, and tilts gradually so as not to loose its free and open, cigarette-feeding connection to the compartment in the rotating cylinder. Similarly, a cigarette-removing channel at the bottom of the cylinder is tiltably mounted. Between these channels, successive, horizontal rods are moved into, downwardly along, and ultimately from each compartment, with the aid of a further tilting mechanism, to provide supports for the cigarettes stored in the compartments. The channels have gates which are operable as additional cigarette support or stop means.
