Filed: 1931-08-12
Abstract: 369,855. Auxiliary air admission. ISDAHL, E., 11, Bergens Gate, Oslo, Norway. Aug. 12, 1931, No. 22813. [Class 7 (ii).] Formation of a vacuum in the cylinders during overrun is prevented by a valve 4 which can only be opened, to admit air to the induction pipe 2, when the main throttle valve 1 is closed. The valve 1 is opened from an accelerator pedal 16 through a linkage 8 .. 13 and a lost motion device 20 allows anticlockwise rotation of the pedal 16, about a pivot 14, to close a switch 27 and so complete a circuit through a solenoid 6 which attracts an armature 5 and snaps open the air valve 4. Alternatively the connection with the valve 4 may be mechanical and comprise an additional lost motion device and a spring-actuated snap mechanism.

Abstract: 446,149. Chucks. THOMPSON, G. H., 947, Bristol Road, Selly Oak, Birmingham. Aug. 21, 1935, No. 23432. [Class 83 (iii)] A combined clutch and chuck for power driven hand tools, such as grinding and polishing heads, comprises a non-rotary casing containing a split collet for gripping a polishing tool or an article to be polished, axial motion of the collet within the casing causing it to be engaged with or disengaged from a conical surface on a continuously rotating driving shaft so as to engage or stop the drive and simultaneously grip or release the tool &c. In one form, for gripping externally, the core 1, Fig. 1, of a flexible shaft is connected by a coupling 2 to a spindle 3 rotatable within a stationary casing 4. A thrust bearing 5 is located between a collar 6 on the spindle and a bush 7 screwing in the casing 4. A bevelled sleeve 9 is screwed to the outer end of the spindle and receives a split conical collet 10 which is normally urged outwardly by a spring 11, but may be forced inwardly by an outer sleeve 14 screwing on the casing and having an end flange 13 acting on the collet through a thrust bearing 12. To release the shank 15 of a tool such as a polishing head, the sleeve 14 is unscrewed from the casing 4, whereupon the spring 11 forces the collet 10 out of the sleeve 9 to release the shank and stop the drive. In a modified construction for gripping internally, the spindle 3, Fig. 2, is extended and provided with a cone 16 engaging an inner bevelled surface on a split collet 17 which is moved axially to grip the tool or work 25 by screwing the outer sleeve 18 on the casing 4, the thrust bearing 20 being located between the flange 18 of the sleeve and a washer 21 secured to the collet by a nut 22. A spring 23 releases the collet.

March 29, 1933, No. 23463/34. Convention date, March 31, 1932. Divided out of 417,597. [Class 40 (ii).] Consists in means for photographically copying, by optical projection, a sound record mechanically engraved on a film or the like as a groove of constant transparency, the copying being such that a transverse enlargement of the image of the groove is obtained (i.e. an enlargement of the amplitudes represented by the edges of the groove). According to the invention, use is made of a printing machine of the known kind shown, in which the negative film 1 and the print film 6 are run through the gates 4, 7 at the same speed, but instead of the usual spherical projecting lens 8, a cylindrical lens is arranged with its axis parallel to the direction of travel of the films. Alternatively, a spherical lens giving high magnification may be employed, in conjunction with a very narrow slit interposed between the lens and the print film. Specification 417,644 is referred to.

Abstract: 1,109,693. Separating entrained liquid from gas streams. SOCIETE ALSACIENNE DE CONSTRUCTIONS ATOMIQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE "ALCATEL". 2 June, 1965 [5 June, 1964], No. 23519/65. Heading BIT. Entrained liquid particles are removed from a gas stream by directing the stream through a converging nozzle, which accelerates it to almost sonic speed, on to a wall 2, whereby the liquid particles break on and drain from the wall, while the velocity of the gas after it impinges on the wall is considerably reduced to minimise re-entrainment. The wall 2 may be smooth, rough or covered by metal fibres 3. The arrangement shown is attached to the high pressure side of an oil sealed vacuum pump, whose volumetric flow rate on the outlet side decreases with the pressure on the vacuum side. Spring loaded valves 4-7 open at different pressures, so that as the flow rate falls individual nozzles are taken out of operation, whereby the velocity of gas in the remaining nozzles remains sufficient to effect separation. Nozzles may be of different diameters.

Filed: 1963-06-13
Abstract: 1,037,288. Cathode-ray tubes; semi-conductor devices. HUGHES AIRCRAFT CO. June 13, 1963 [July 23, 1962], No. 23614/63. Headings H1D and H1K. A moving target indicator tube, of the type cancelling unchanged information signals, comprises a low velocity scanning beam and a target including a conductive backplate and layers of semi-conductor material forming a rectifying barrier therebetween, the target having a capacitive time constant greater than the frame scanning period. As shown, input signals are applied to cathode 14, Fig. 1, and target 26 is charged to the instantaneous cathode potential. Subsequent scans replace charge lost by leakage so that for unchanging information a constant current flows through signal resistor 38. However, changes in a periodically-recurring signal input cause fluctuations in the output until new equilibriums are reached. The target may comprise a conductive glass or nickel back-plate 24 carrying an N-type cadmium selenide layer and an outer P-type selenium layer, or two layers of the same type, one being more heavily doped than the other, so that unchanging information produces a small constant output current. Since changing input pulses of opposite polarity produce asymmetrical output signals, i.e. a small decrease to zero current or a large current increase, each input pulse of either polarity may be replaced by two equal and opposite pulses.
