Patent ES-350993-A1 (ES)
Title: Rotary valve
IPC: F16K1/20
Filed: 1968-02-27
Abstract: In a rotary valve having a circular seat 58 and a closure member with a substantially rigid spherical face 65 joined by deformable portions 63 to a hub 61 splined to a rotatable shaft 40, the axis of the shaft 40 is offset with respect to the central axis C of the valve head 64 and the flow axis A of the valve so that when the shaft 40 is rotated to seat the face 65 on the seat 58, the face 65 first contacts the latter at P when further rotation of the shaft 40 causes the valve head 64 to pivot about P until the face 65 is fully seated, the portions 63 deforming. The shaft 40 is rotated by a ram 21 acting through a lever 50 fast on the end of shaft 40 which extends through a tubular portion (35) of the housing to which a bracket 42 supporting the ram is secured. A manual handwheel 53 on a shaft threaded into a bore of the bracket and acting on the end of the lever 50 remote from the ram 21 can be used to actuate the valve or as an adjustable stop. The shaft 40 is mounted in bosses 36, 37 integral with the housing or in a modification in bosses formed in a tubular arm connected in an aperture of the housing and having an L-shaped arm extending internally across the housing and supporting one end of the shaft 40. The seat 58 has an annular shoulder and is retained in the stepped bore by a ring nut 59 and in a modification can project into the valve chamber 32. A pointer on the lever 50 and indicia on the bracket 42 give an indication of the closure member position. A grommet 90 (Fig. 14) which surrounds the piston rod and allows it to move laterally in a slot of the housing of the ram has a square sectioned body 91 with a central bore and two end flanges 92, 93, each with a vent hole 94, 95 therethrough.
Patent ES-352053-A1 (ES)
Title: Thermostatic regulating device with a synthetic thermoplastic expansion element
IPC: A47K3/28
Filed: 1968-03-27
Abstract: A thermostatic valve is operated by an expansion element 27 of a thermoplastic synthetic material such as polyethylene or polypropylene, the element preferably having a generally tubular cross-section, whilst over at least a part of its length 27a, the wall thickness of the section does not exceed 2 mm. to ensure that the element has a suitably quick response to temperature changes. The valve as described relates to a mixing tap for a shower in which a double-acting valve element 16 reciprocable in a sleeve 17 controls the relative amounts of hot and cold water from inlets 2, 3, the mixture passing over the element 27 in a tubular housing 6 leading to an outlet 5, the expansion element 27 controlling the position of the valve element 16 to maintain the temperature of the water leaving the outlet 5 constant. One end of the expansion element is connected to a screwthreaded member 44 allowing adjustment of the water outlet temperature and the other end is connected directly to the valve element 16 through the agency of springs 35, 351 which prevent damage to the element due to overloading after the element has seated against either of the valve seats 20 or 21. The part of the expansion element 27a which has a wall thickness of less than 2 mm. is located upstream of the water flow and a further part 27b with a thicker wall section is also provided at the downstream end, the two parts co-operating to maintain the desired temperature, the thinner section 27a providing quick response to inlet water temperature changes and the thicker section the desired stability in the outlet temperature and prevention of over-compensation by the effects of the thinner section. The downstream end of the expansion element 27 may be closed to provide a stationary column of water inside the element and thus a degree of thermal insulation for the thicker end part 27b. A tube 29 is interposed between the element 27 and the housing 6 with a flexible guiding ring 30 positioned so that in conditions of a low flow rate the water largely flows along the expansion element, the ring being deflected to allow water to pass between the tube 29 and housing 6 at higher flow rates.
Patent ES-353943-A1 (ES)
Title: Thyristor inverter
IPC: H02M7/523
Filed: 1968-05-16
Abstract: In an invertor (e.g. for induction heating), thyristors T1, T2, T3, T4 (Fig. 1) connected to a D.C. source E (or a rectified A.C. source) by a capacitive voltage divider C1, C2, C3, C4, are fired sequentially by four phase firing pulse trains 1, 2, 3, 4 (Fig. 2) respectively, to pass current through a transformer half primaries P1, P2 and produce a sinusoidal output at a frequency N from a secondary S1 which is tuned by a capacitor C. In each firing pulse train the pulses have a recurrence frequency of N/4 and a repetition period T = 4/N. The pulse trains are successively phase shifted by T/4 (as shown). Each thyristor may be replaced by a plurality of thyristors in series and parallel, all of the thyristors in one stage being triggered by the same drive signal. Operation.-A drive pulse 1 fires T1 which conducts. C1 behaves as a voltage source and delivers current through T1, P1, L1, C5. This current passing through L1, C5 (having a natural frequency N/2) first changes C5 to its peak voltage then falls to zero after a half-wave having a time duration T/4, then begins to reverse and blocks T1. At the instant T1 is blocked a drive pulse 2 triggers T2 to conduction. C5 adds its voltage to that of C2 and both discharge through L1, P1, T2, thus delivering a current half-wave through one half of the primary P1. This halfwave has the same direction and duration T/4 as the previous half-wave through the primary as before when current begins to reverse T2 is blocked and a pulse 3 triggers T3 into conduction and an identical cycle of operation is initiated in the circuits including T3, T4, P2, C3, C4, C6. In the secondary S1 there is produced a series of signals having a period T/4 and therefore a frequency N. Sl is tuned to frequency N by a capacitor C and a sinusoidal current is applied to the load Z at a frequency N. Overvoltage due to current interruption in the thyristors is limited by a secondary winding S2 in series with a diode D. Firing circuit (Figs. 3 and 4, not shown).- Two bi-stable units, each arranged as a frequency divider, are fed respectively with signals in anti-phase from an a stable multivibrator. The first bi-stable unit produces two square wave pulse trains in anti-phase, as does the second. The signals from the second unit are, in addition, displaced from those of the first so that 4 phased square waved signals are produced, from the leading edges of which the firing pulses are derived. The pulses may be applied to the thyristor gates via isolating transformers and buffer stages. Likewise 8 phased signals can be produced to excite 8 thyristors and so on.

Patent ES-442690-A1 (ES)
Title: Method and apparatus for testing antibiotic susceptibility
IPC: G01N35/00
Filed: 1975-11-17
Abstract: The light scattering of a number of aliquots of a given bacterial/broth suspension, each containing a different antibiotic are rapidly measured and compared with the forward light scattering of a control suspension of the bacteria in the absence of antibiotic. The inhibitory effectiveness of each antibiotic on the growth of the bacteria is then computed from the substantially simultaneous readings and printed out. The bacterial/broth suspension samples are conveniently deposited in a disposable, plastic, transparent, compartmented container or cuvette into which antibiotic discs are introduced into all but one compartment (chamber) from a ganged disc dispenser. After a brief agitated incubation period of about three hours, the covette is inserted in a photometric analyzer which measures the intensity of light scattered at some angle to the incident beam by each sample chamber and compares it with the light scattered at the same angle by the control chamber to which no antibiotic has been added. The relative effectiveness of each antibiotic is computed and recorded to determine which of the antibiotics is most suitable for treating the patient. The partitioned cuvette includes a filling reservoir from which the inoculated broth is introduced as equal volume aliquots into the interconnected lobes of a row of double lobed chambers. Rotation of the partitioned cuvette transfers the equal volumes of broth inoculum from the interconnected lobes to the transparent and separated lobes of the chambers. Then different antibiotic discs are simultaneously dropped within apertured tubes which are located within all chambers except the control chamber. Elution of the antibiotics into the liquid samples begins immediately. The cuvette is then placed in an incubator/shaker for approximately 3 hours at approximately 36 DEG C to promote bacterial growth and antibiotic elution. The light scattering readings are obtained at the end of the agitation/incubation period and the relative antibiotic effectiveness computed in an analyzer into which the cuvette is inserted and indexed past a light source. The light passes through a lens system which directs a beam of light successively through the transparent lobes of the cuvette. The readings are obtained at a predetermined angle of scatter of, for example, 35 DEG . Initial analog signals are converted to binary digits and logarithms to simplify normalization of the antibiotic-mediated inhibition of bacterial growth by the total growth in the control chamber. The normalized growth inhibition values are printed out and rated on a scale of 0 (no inhibition, total resistance) to 100 (complete inhibition, total susceptibility). In addition the total growth, which has occurred in the control chamber during the agitation/incubation period, is printed out as a logarithmic difference (growth index).

Title: Process and apparatus for controlled recycling of combustion gases
IPC: B01F23/10
Filed: 1976-02-12
Abstract: Formation of nitrogen oxides and/or soot is obviated by mixing recycled combustion gas with incoming comburant supplied to a burner via a distribution opening and controlling the mass flow rate of combustion gas being recycled with respect to the mass flow rate necessary for the gaseous comburant, the mixture being passed to the burner as a turbulent flow in which the ratio between the kinetic momentum flux of the mixture and the product of the radius of the said distribution opening times the axial movement quantity flux of the mixture has a value at least sufficient so that the said turbulent flow produces a recirculation of the said mixture within the combustion chamber in the form of a toroidal vortex. This is achieved by apparatus comprising a mixing enclosure having two inlets each provided with means for regulating the size of its aperture, and an outlet, inlets communicating respectively with the atmosphere and with a duct for combustion gases, the outlet being connected to the inlet of a ventilator whose outlet communicates with gas mixture supply means arranged coaxially to a fuel injection nozzle in order to impart a turbulent motion to the gas mixture emitted from the supply means.
