Patent ES-317061-A1 (ES)
Title: Apparatus for rendering extremal the value of an installation operating criterion
IPC: G05B13/02
Filed: 1965-09-02
Abstract: An arrangement for providing optimum operation of an automatic control system comprises continuously producing a pilot signal whose value is a linear function of at least one of three quantities, a controlled variable, its first time derivative, or its second time derivative, comparing the signal with a plurality of reference signals and triggering off a searching cycle at a predetermined time intervals and when the amplitude of the signal reaches either a first positive or a second negative value, the searching cycle consisting of two successive phases, the first in which a parameter control led is made to vary progresssively in accordance with a predetermined law and the second phase being triggered off and the signal passes while decreasing in amplitude through a third value, the regulating variable being acted on in dependence of a first periodic signal and a signal which is proportional to the time integral of the product of the signal and a second periodic signal of the same frequency as the first, and stopped when the aperiodic component of the signal reaches a fourth boundary value. In a temperature control system a heat generator G is fed with liquid fuel 1 and air 2 to heat a fluid the temperature 6 of which is measured at 5 and passed with a reference signal # c to an amplifier 6 the output of which is passed through a proportional plus integral plus derivative means which controls a fuel valve 3. The amplified error signal is also passed to an apparatus CD in which it is compared with reference signals #1-#5 successively to initiate the searching phase causing the air to be varied by a signal Sr controlling a valve 4 in a manner described above. In this embodiment the variations of air-flow are made entirely in the excess air region to avoid the risk of explosion due to excess of fuel. In a chemical reaction, the parameter to be optimized could be the efficiency of a reaction or the quality of a product where an operating criterion depends on a plurality of regulatable quantities, the first phase for each being carried out successively and the second phase being carried out simultaneously. Common measuring detecting and logic circuits may be provided for all the quantities. The relays described for example in connection with Figs. 4 and 6 (not shown) may be replaced by semi-conductor elements, and the electric circuits by equivalent fluid modules e.g. operated by compressed air or liquid. Integration in the arrangement may be performed by impulse counts. The arrangement may be additionally controlled by a programming means.

Title: Process for freeing animal feeds of salmonella
IPC: A01M17/00
Filed: 1968-06-28
Abstract: In a continuous process of destroying salmonella in animal feed meals, the meal supplied by hopper 9 is heated in screw conveyer 10 to at least 165 F. by admixture with dry live steam, maintained in turbulent motion and at at least 165 F. for 20 mins. in heated bin 30, and cooled to below 120 F. in screw conveyer 60, which is surrounded by a cooling liquid jacket. The treated meal is subsequently ground, sieved and packed. In the initial stages of the process the meal from bin 30 is recycled to the top of the bin and this recycling process is maintained till the bin is full enough such that the time taken for the meal to pass through the bin is at least 20 mins., when the recycling process is automatically stopped. After the initial stages the meal is fed to and withdrawn from the bin 30 at equal rates. The conveyer 10 comprises a jacketed trough provided with steam or electric heating coils to preheat the conveyer 10. Steam is only admitted to screw conveyer 10 when meal is being supplied by hopper 9. In the bottom of the bin 30 there are a series of augers which lead the meal to reversible conveyer 75 driven by reversible motor 78, which conveyer 75 feeds the meal to recycling means 45, 46, 44 or to cooling conveyer 60.

Title: Power supply with reversible static inverter - is coupled to battery and to load and AC supply via resonant transformer
IPC: H02J9/06
Filed: 1968-10-17
Abstract: The no-break power supply switches load to output of static inverter coupled to battery when main ac supply fails. The same inverter circuit is used to charge the battery during normal operation. The output of the inverter is coupled to a transformer (T1) acting as a constant voltage transformer with resonant circuit (4). The ac supply (6) and the load (7) are connected to one of this transformer windings (3) and in series with inductors in the resonant circuit. A phase sensitive control (8) adjusts the power of the reversible inverter in both directions depending on the ac supply voltage. The advantage lies in simplicity.

Patent ES-388046-A1 (ES)
Title: A mobile apparatus for a radiomobile telecommunications system integrated with the public telephone network
IPC: H04W48/16
Filed: 1971-01-26
Abstract: In a system having mobile subscribers connected via radio channels to the public telephone network, each subscriber set includes a coding matrix whose columns are sequentially read-out automatically so as to cause a two-out-of-six tone generator to transmit the set's identity whenever the set goes off-hook at the beginning of a call or whenever its call detector responds to an incoming calling signal at the beginning of a call. A wanted subscriber's number is setup, prior to going off-hook, on another matrix whose columns are read-out in a similar way after the set identity code has been sent. If two or four or six &c. successive digits are the same, a special repetition code is transmitted instead of the normal digit code for the second, fourth &c. digit, a set of comparator gates being provided for this purpose. A number may comprise up to ten digits. All numbers (wanted or own) are prefixed and suffixed by respectively "start message" and "end message" two-tone codes. The two-out-of-six generator comprises two frequency selective circuits which are energized by weighted 2-out-of-6 codes derived from the markings in the matrix columns. A single channel is used for signalling to and from the mobiles. Each mobile's speech transceiver normally rests on the channel to which it was tuned during the last call so that this channel becomes first choice on subsequent calls. If a "channel occupied" signal, e.g. the carrier, ceases, e.g. due to fading, during a call, the set is cleared down after a predetermined time. It is also cleared, if a free channel cannot be found, on hanging up the telephone instrument and on receipt of an "end-call" signal from the exchange. Detailed logic circuitry for performing all the functions mentioned above is given in the Specification.

Patent ES-406627-A1 (ES)
Title: Shaft coupling mechanism
IPC: F16D1/116
Filed: 1972-09-13
Abstract: Mechanism for coupling an externally splined power take-off shaft with a hollow internally splined shaft, comprising a plurality of locking elements radially movable between inner locking and outer unlocking positions within a like plurality of circumferentially spaced apertures in the wall of the hollow shaft, the elements being engageable in the former position with a circumferential groove in the power take-off shaft to lock the shafts against relative axial movement. A retaining member is axially slidable on the periphery of the hollow shaft between a first position wherein it surrounds the locking elements and prevents their disengagement from the groove in the power shaft and a second position wherein the elements are free to move to their unlocking position, the member being biased toward the former position. A latch ring on the hollow shaft is operable to move the retaining member from its first to its second position, and is engageable with a recess in the periphery of the hollow shaft to lock the member in the latter position. As the hollow shaft is inserted onto the power take-off shaft, the latter engages and moves the locking elements radially outwardly against the latch ring, thereby disengaging the ring from the recess in the hollow shaft and permitting the retaining member to move back toward its first position.
