Patent ES-343548-A1 (ES)
Title: A process for producing {60 -amino acids
IPC: C07D233/72
Filed: 1967-07-28
Abstract: A process for producing alpha -amino acid by hydrolyzing a hydantoin compound in which the hydrolysis is effected while withdrawing out of the system ammonia and carbon dioxide generated during the hydrolysis and while during the reaction period, adjusting the amount of reaction medium to at least 1.5 l. per mole of the hydantoin compound initially employed. Particularly, a process in which the hydrolysis is effected in such a manner that an aqueous alkaline solution of hydantoin compound is fed to the upper part of a plate column-type reactor or packed column-type reactor and, simultaneously, steam is fed from the lower part of said reactor, while withdrawing ammonia and carbon dioxide out of the system. By thus effecting the hydrolysis without concentrating the reaction liquid, and while withdrawing the generated gases out of the system, alpha -amino acid can be produced in high yields.

Title: Improvements in or relating to a road-traffic counting device for motor vehicles
IPC: G08G1/042
Filed: 1967-10-24
Abstract: In a road traffic counting arrangement, for motor vehicles, three adjacent induction loops I, II and III are positioned transversely to the axis of the roadway and a counting means including logical circuits prevents data supplied by a detector D2 associated with the middle loop II from reacting a counting means K when either one or both of the detectors D1, D3 associated with the outer loops I, III is excited. The loops are arranged across a two lane roadway and the middle loop II has a width at least equal to the maximu width of the largest vehicle so that one vehicle cannot energize both loops I and III. Each detector D1, D2, D3 controls via contacts d1, d2, d3 (Fig. 2b) a relay M, N, P which have normally open contacts m1 n1, p1 (Fig. 2c) connected to a counter K. The relays M and P associated with the outer loops I and III have in addition to normally open contacts two normally closed contacts m2, p2 connected in series with the open contact n1 of the relay N associated with the middle loop II. This arrangement ensures that when either one or both the outer loops I and III are energized the circuit including the contacts m2, p2 is open. The operation of the contacts n1 associated with the middle loop is delayed with respect to the contacts of the other loops by an R.C. network connected to its relay N or by placing the leading edge of the middle loop II behind that of the other loops (Fig. 1, not shown) so as to ensure that the relays operate in the correct sequence. To avoid supplying a pulse to the counter K when the contacts m2 and/or p2 release with contact n1 still closed the relays M and P associated with the outer loops include holding contacts m3 and p3 connected in series with normally open contacts actuated by the relay N associated with the middle loop. The loops may be trapezoidal, rhombic or oval in shape. The detectors D may be bi-stable electromechanical, electrical and/or electronic and the relay arrangement can be electronic.

Patent ES-365039-A1 (ES)
Title: Induction meter having light-load adjuster
IPC: G01R11/36
Filed: 1969-03-21
Abstract: A light-load adjuster for an induction meter comprises a movable pair of arms 67, 69 of magnetic material which intercept the fluxes passing through the polefaces 13A, 15A, Fig.2, of two poles 13, 15, Fig.1, of the voltage core 2. The arms 67, 69 resiliently engage the polefaces 13A, 15A and form integral parts of a lever 71 of magnetic material pivoted (at 73) on a bracket 75 of non-magnetic material which in turn is riveted to the sides of the two poles 13, 15. The lever 71 is rotated by a screw-nut arrangement 78-81 to move the arms across their respective polefaces. The flange 75B of the bracket 75 also serves to space a magnetic shunt 83 from the outer poles 13, 15 of the voltage magnetic circuit, the shunt being spaced from the centre pole 11 by a headed stud 84 of brass or aluminium. A further shunt 29 is riveted to the other side of the outer poles 13, 15 and spaced from the centre pole 11 by a conductive tube 37. A magnetic screw 33 passes through this tube into an opening 35 in the centre pole 11, its penetration into this opening determining the effective load provided by conductive tube 37 on the voltage coil 5, and hence the phase angle between the voltage and current fluxes. Temperature compensation is provided by a sleeve 39 of an austenitic iron-nickel alloy having a negative temperature coefficient of permeability which also surrounds the screw. To compensate for variations in the supply voltage, a magnetic tongue 61 extends downwards in Fig. 1 from the strip 29 and has a portion extending underneath the disc 23 to face the pole 11. The cross-section of the tongue is reduced by a hole 65 so that it becomes saturated when the full rated volatge is applied to the coil 5 but is unsaturated at lower voltages. The meter may be used in a single or polyphase circuit for indicating or integrating watts or reactive volt-amperes.

Title: Antiskid device for a vehicle braking system
IPC: B60T8/60
Filed: 1971-05-31
Abstract: An electronic anti-skid device for a vehicle braking system, operative upon actuation of the brake pedal to periodically apply the brakes and isolate the braking system from the brake pedal under the control of signals representative of the wheel acceleration. During the periods when the braking system is isolated, the wheel acceleration curve comprises a negative portion followed by a positive portion having a peak value. With this device, the periods when the braking system is isolated are ending shortly after the wheel acceleration has reached its peak value. This is obtained by comparing the positive portion of the acceleration signal with the output signal of a time-constant circuit having a discharge curve which intersects the acceleration curve in the neighborhood of the peak value.

Patent ES-403708-A1 (ES)
Title: Arrangement for disengaging threading dies in a threading die head
IPC: B23G5/12
Filed: 1972-05-31
Abstract: For disengageably securing threading dies in the head of a thread-cutting machine or a similar device, axially extending holding bolts are provided in a die carrier for locating the dies in the threading position. The ends of the holding bolts spaced from the dies are secured to a flange displaceably mounted on the die carrier. A slide bushing is in threaded engagement with the flange and extends axially through a bore in the die carrier. A sensing bolt extends through the slide bushing and has a contact surface on one end for contacting a workpiece being threaded. Springs are located in the die carrier for biasing the flange away from the dies. While the workpiece is being threaded, the slide bushing is held against displacement in the axial direction relative to the die carrier, however, when the threading action is completed the sensing bolt is displaced axially and releases the locking action between the slide bushing and the die carrier. As a result, the flange connected to the slide bushing is biased by the spring so that the holding bolts release the dies from the threading position.

Patent ES-436795-A1 (ES)
Title: HTGR power plant hot reheat steam pressure control system
IPC: G21D3/08
Filed: 1975-04-21
Abstract: A control system for a high temperature gas cooled reactor (HTGR) power plant is disclosed wherein such plant includes a plurality of steam generators, each deriving heat from a respective circulating flow of reactor coolant gas to supply superheated steam to a common main steam header and reheated steam to a common hot reheat header. Dual turbine-generators are connected to the common headers, a high pressure element of each turbine receiving steam from the main steam header, and an intermediate-low pressure element of each turbine receiving steam from the hot reheat header. Associated with each high pressure element is a bypass line connected between the main steam header and a cold reheat header, which is commonly connected to the high pressure element exhausts. Associated with each intermediate-low pressure element is a first bypass line connected between the hot reheat header and a respective condenser, and a second bypass line connected between the hot reheat header and an alternate steam receiving means such as a secondary condenser or atmosphere. The reactor coolant gas is circulated through each steam generator by an associated helium circulator which is rotated by an auxiliary steam turbine connected between the cold reheat header and the reheater section of the respective steam generator. A control system governs the flow of steam through the first and second bypass lines to provide for a desired minimum steam flow through the steam generator reheater sections at times when the total steam flow through the turbines is less than such minimum, and to regulate the hot reheat header steam pressure to improve control of the auxiliary steam turbines and thereby improve control of the reactor coolant gas flow, particularly following a turbine trip. When the desired steam flow through an intermediate-low pressure turbine is less than the predetermined minimum, the control system governs the flow of steam through the first bypass line so that the combined turbine and bypass steam flow is equal to the predetermined minimum. The steam flow through the second bypass line is controlled to regulate the flow of steam through the first bypass line at a predetermined variable limit value. At times when there is a difference between detected and desired values of hot reheat header steam pressure, the control system reduces such difference by varying the steam flow through one of the bypass lines in proportion to such difference. The steam flow through the second bypass line is varied only when the flow of steam through the first bypass line is at the predetermined variable limit.

Filed: 1975-11-27
Abstract: A contact bar of novel design is provided for use in electrolytic cells of the type which have alternating, equally spaced, anodes and cathodes. The electrodes each have header bars, and each header bar has an extending end portion which is notched on its underside. The contact bars of the invention are useful in such cells when employed in the electrolytic recovery of metals such as copper, cadmium, cobalt, lead, nickel, silver and zinc. The contact bars are generally cyclindrical, and have cylindrical end sections and a spooled central section. The spooled central section is created by forming a plurality of alternately identical grooves with center lines equally spaced along the length of the spooled central section. The sidewalls of the grooves are sloped and form right frusto-conical walls which face one another on opposite sides of the groove. This spool-shaped contact bar provides excellent electrical contact via the notched portion of the header bars, the weight of the electrodes insuring high pressure contact between the notched header bars and points located on the sidewalls of the grooves. The contact which is created may aptly be described as a "sloping-tangent contact".
