Title: Carburettor having an automatic choke
IPC: F02M1/14
Filed: 1972-11-21
Abstract: 1407600 Fluid-pressure servomotor systems FORD MOTOR CO Ltd 21 Nov 1972 [27 Dec 1971] 53691/72 Heading G3P [Also in in Divisions F1 and F2] The choke valve 28 of a carburetter is biased against the air-flow tending to open it by a thermostatic spring 60 and the spring force is opposed by a servo 90 responsive to the vacuum downstream of the throttle valve 36. The servo chamber 144 is subject to the vacuum through a sintered metal plug 106 and a central opening in an elastomeric valve disc 108. The rate of increase of vacuum in the chamber 144 is restricted by the plug 106 and the plug is by-passed through a slot 105 when the pressure in the passage 100 rises above that in the chamber and the disc 108 moves away from the plug. A bi-metallic washer 126 carries an elastomeric valve 130 which flips from a position closing the passage 124 to a position opening the passage above a predetermined temperature, e.g. 65F, to permit the vacuum to act on the servo diaphragm 140. The spring 60 is subject to the temperature of air passing through passages 68 and 70 into its housing 42, 66, e.g. from an exhaust manifold heater, and acts through an angularly adjustable shaft 48 on the valve 28. A piston 78 subject to the vacuum downstream of the valve 36 acts on the shaft 44 in opposition to the spring 60 and provides partial opening of the valve 28 immediately on engine starting, a lost-motion connection 152, 154 between the valve and the servo 90 permitting this opening.

An appliance, stated to be for drawing circular curves, comprises a rigid rule 1 with a groove 3, the shape of which is defined by a given equation, and a slide member 4 consisting of a flexible guide rail 6 slidably engaging the groove 3 and a number of resilient transparent strips 5 which are attached to one another and to the guide rail 6 so as to be slidable lengthwise relative to one another. As the slide member 4 is moved along the rule 1, its inner and outer edges assume the shapes of circular curves, the radii of which are indicated by a marker line 7 on the slide and graduations 2 on the rule 1. In making the slide member 4, the assembly of strips 5 is cut along a line which, if the member 4 was placed in position A with the long sides tangential to the groove 3 at a reference point where the radius of curvature of the groove is infinity, would lie along the line of the groove. The rail 6 is inserted between the two parts so formed and the strips 5 are welded to the rail at the narrow end of each part, and are connected together by any suitable means which allows of lengthwise sliding of the strips on one another. In one modification (Fig. 5), the two parts, of the member 4 are slidable along the two edges of the rule 1 and in another modification (Fig., 4), the member 4 is arranged below the rule 1.

Abstract: 1452779 Gettering SAES GETTERS SpA 14 Dec 1973 [14 Dec 1972] 58037/73 Heading H1D A getter device comprises a metallic or ceramic foraminated support 20, which consists of a threedimensional network 21 which defines a plurality of inter-connecting cavities, and has powdered getter material contained in at least a part of the network. The getter materials may be evaporable, e.g. Ca, Sr, Mg and Ba, and alloyed with other metals, the particulate alloy being mixed with another particulate metal which reacts with the alloy on heating to release the getter by exothermic action. Alternatively the getter materials may be non-evaporable, e.g. Ti, Zn, W, Th, V, Ta, Nb, Hf and V, and may be alloyed with e.g. Al, Ce, Mn or mixed in divided form, e.g. a mixture of Ce and La. For use at temperatures from room temperature to about 400‹C, the particulate getter may be mixed with an anti-sintering agent such as graphite, or with a particulate Zr-Al alloy. Refractory oxides or carbides may be added. If the cavities are large, the powder is poured in, with mechanical or ultrasonic vibration as required. It is preferred, however, to form a suspension of the powder in a liquid and to immerse the support therein. The support is then heated to 800-1200‹C. As shown, the foraminated block 20 is filled with powdered Zr ( a non- evaporating low temperature getter) mixed with powdered Zr-Al alloy. Alternatively, a foraminous Ni-Cr alloy block is filled with Zr powder mixed with graphite powder. In a particular example, particles of Zr and graphite form a suspension in ethanol, and a foraminated disc of Ni-Cr alloy is immersed therein, and then placed in vacuum of 10<SP>-5</SP>-10<SP>-6</SP> torr. The temperature is increased over 25 minutes to between 800 and 1100‹C, and maintained at that temperature for 5 minutes. The disc is then allowed to cool to room temperature. The getter is placed in its evacuated enclosure and activated by heating to 900‹C for 10 minutes. The graphite may be replaced by Zr-Al alloy. In experiments, the getter was tested for absorption of gas. A cylinder of foraminated Ti was filled with getter and heat treated. When argon and hydrogen were passed through the getter, the impurity content was reduced.
