Abstract: 1484084 Regulating IC engines exhaust recirculation REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 21 Oct 1975 [25 Oct 1974] 43220/75 Heading F1B [ Also in Division G3] In an I.C. engine, exhaust gas recirculation is controlled according to the sensed exhaust gas composition, and engine carburreter by-pass air is controlled by the measured pressure in the recirculation duct. As shown, the main air duct to the engine 1 is via filter 5 and carburetter 3, and secondary air to the engine supplied from the filter 5 via duct 22 and valve 21. A signal from exhaust gas composition sensor 16 is used by controller 15 to control a solenoid valve 13, 14 in the engine recirculation duct 7. The pressure in a cooling and mixing chamber 10 of this duct is measured by a diaphragm 18 which is mechanically coupled to, and controls, valve 21. Enginal hunting is said to be prevented by the arrangement shown since the secondary air supplied by duct 22 is proportional to the rate of flow of the mixture to the engine, and flow of secondary air is corrected in dependence upon engine exhaust gas composition and pressure. Using the present system, oxides of nitrogen, hydrocarbons and unburnt carbon monoxide in the exhaust gas are reduced.

Abstract: 1,064,225. Pulse modulation circuits; circuits employing non-linear capacitors. CESKOSLOVENSKA AKADEMIE VED. Nov. 4, 1964 [Nov. 5, 1963; Nov. 6, 1963; Dec. 4, 1963], No. 44938/64. Headings H3B and H4L. [Also in Division G1] In an electrometer type voltage measuring arrangement, a D.C. voltage to be measured is applied across a non-linear capacitor C N  which is connected in series with an A.C. generator G and a linear capacitor C 1 . The linear capacitor is connected to the input of a limiter O, so that the limiter is supplied with A.C. which passes through zero value in dependence on the D.C. input to the non-linear capacitor. The duty cycle of the rectangular output voltage of the limiter is then dependent on the input voltage. In a practical embodiment (Fig. 3, not shown) the input voltage is supplied through a filter (F1) which prevents the generator voltage reaching the input. The limiter (O) may be either a limiting amplifier or a flip-flop circuit, and the difference between the average value of the limiter output and the output of a compensating source is indicated on a meter (M). In a further embodiment (Fig. 4, not shown) the A.C. component is filtered from the limiter output signal which is then fed back, via a differential amplifier to the circuit input. This negative feedback substantially reduces the input capacity of the circuit and increases its input resistance. To compensate for changes in circuit characteristics due to temperature effects, ageing &c., two opposed similar circuits incorporating two non-linear capacitors and two limiters, but operated from one generator may be used (Fig. 6, not shown). One non-linear capacitor is controlled by the unknown voltage to be measured, the other by a reference voltage. The outputs from the two limiters are fed to opposite sides of a differential meter. To provide improved stability, the A.C. from the generator may be amplitude modulated (Fig. 8, not shown). The output from the limiter, after being filtered to remove the supply frequency component, still contains an A.C. component at the modulation frequency, and this is amplified and then rectified in a phase demodulator. The output from this indicates both the magnitude and polarity of the input voltage. This output may be used as before to provide negative feedback.

In a clutch arrangement for a motor vehicle automatic planetary gear-box wherein two friction disc clutches 14, 15 have a common centre abutment 16 and are mounted in a drum 13a formed integral with and to one side of a rotatable flange 11 mounted by a hub 20 on a casing boss 10a, the clutch 15 is controlled to transmit different torques in two different gear ratios by a fluid pressure doubleacting piston 19 connected through a sleeve 18 externally arranged and axially movable on the drum 13a, and formed at its opposite end with a presser plate 17 for actuation of the clutch 15, the piston 19 being arranged on the other side of the flange 11 and formed on each side with large and small piston surface areas 23, 24 which may be independently operated by fluid pressure supplied through a duct 26, or 27, to cylinder chambers 25, or 28, for engagement, for high torque transmission in one gear ratio, or release respectively of the clutch 15, or, may be simulaneously operated to effect a differentially reduced loading of the clutch 15 for transmission of a smaller torque in another ratio, the clutch in this condition being disengaged simply by relieving the pressure on the piston surface 23. The arrangement avoids the use of complicated oil pressure controls, and clutch springs are dispensed with by the double-acting piston which when operated for clutch disengagement, rapidly overcomes centrifugal residual pressure remaining in-the cylinder space 25 after release of the fluid pressure from the piston surface 23. The clutch 14 is independently controlled by a separate single. acting piston mounted on the right-hand side of the flange 11.

Title: Sterilization
IPC: A61L2/07
Filed: 1976-11-02
Abstract: The method comprises the following steps:   - insertion of the articles in a container suitable for storing and transporting the articles; - arrangement of the container in an autoclave, fluid exchange between the interior of the container and the interior of the autoclave being possible; and - heating-up of the container and its contents to the sterilisation phase.   The container (10, 12) has an opening (50) and a resilient valve element (60) which is pretensioned in its closed position. This valve can be opened manually, specifically by actuating a lever (74). The lever is held in this position by means of a rigid, yet meltable, element (84), so that the valve remains open. After a sufficient time at the sterilising temperature the element (84) melts and thus causes the valve to be closed. In this simple way articles can be easily sterilised, it then being possible to keep the sterilised articles sterile in this state for a very long period of time. <IMAGE>

Abstract: 1287291 Ion sources PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Sept 1969 [26 Sept 1968] 46804/69 Heading H1D An ion source for a mass spectrometer comprises a gutter-shaped repeller electrode 305, an apertured extraction electrode 303 and an apertured accelerating electrode 306, in which gas in the region 301 is ionized by an electron beam perpendicular to the plane of the paper, wherein the inner wall 304 of the repeller electrode is shaped, as shown, to form a tapered edge portion 308 of the repeller electrode adjacent the extraction gap 302. This electrode configuration produces an electric field distribution in the repeller electrode, Figs. 8 and 9 (not shown), which does not differ appreciably whether the voltage on the accelerating electrode is low, e.g. 80 V., or high, e.g. 2000 V., the extractor electrode having a potential of 1 v. and the repeller electrode being grounded in both cases. Thus, when the ion source is used in a mass spectrometer in which the spectrum of the gas in the ion source is obtained by varying the accelerating electrode voltage, the extraction efficiency of light ions, e.g. of mass 2 with a 2000 V. accelerating voltage, and of heavy ions, e.g. of mass 40 with a 100 V. accelerating voltage, may vary by less than 25%.
