Title: Improvements in Carburetters for Internal Combustion Engines.
IPC: F02M7/14
Filed: 1916-11-23
Abstract: 111,505. Deacon & Son, A., and Berry, J. Nov. 23, 1916. Spray carburettors.-The passage around the nozzle of a spray carburettor is varied by an iris diaphragm which is provided with elastic closing means and with an elastic connexion to the engine ignition-control device; the fuel valve is actuated from the throttle valve, and a by-pass delivers near the edge of the throttle valve. The nozzle outlet d<2> is controlled by a valve E which is adjustably mounted in the screwed boss e<1> of a toothed valve e<4> which gears with a wheel f<2> on the spindle of the throttle valve F. A pipe k<1> conducts fuel to an elongated slot K near the edge of the throttle valve, 'the slot permitting air to pass the edge and mix with the fuel. The diaphragm G is actuated by an arm g<2> on a central spindle g<3> carrying arms g<4>, g<5> of which g<4> is connected to a spring g<6>, Fig. 3, which tends to close the diaphragm, and, through a spring H, to the ignitioncontrol device, so that, as the spark is advanced, the diaphragm is opened. The diaphragm is controlled from the steering column through a quadrant g<8> and a flexible cable g<7> which is normally left slack so as not to interfere with the other control.

Title: Reticulated Nylon Materials and a Method for their Manufacture
IPC: C08J9/38
Filed: 1968-04-09
Abstract: 1,151,483. Reticulated nylon structure. F.M.C CORP. 9 April, 1968 [29 May, 1967], No. 17005/68. Heading C3C and C3R. A reticulated structure formed of a network of interconnected strands of a nylon resin is claimed wherein the strands are integrally connected by junctures at spaced points, the junctures being thicker than the adjacent strands, and form the skeletal outline of a multitude of polyhedrons whose faces are polygonal, are common to a polyhedron adjacent thereto and are open and free from membraneous nylon resin. The reticulated structure is made by subjecting a foamed, closed-cell, cellular nylon resin to an aqueous solution of at least 5% by wt. of a phenol, e.g. phenol, to remove membraneous portions of the foam cells whereby the skeletal network of interconnected strands of nylon remains, removing the phenol solution from the network and drying. In Example (I) a mixture of nylon- 6, azodicarbonamide and zinc powder (as nucleating agent) was heated and extruded to form a foam which was quenched on a chilled roller and then longitudinally stretched by passage over differential speed rolls and stretched in a transverse direction using a tenter frame, the foamed and oriented web was then treated with the aq. phenol still under tension, and the reticulated structure formed was washed with aq. NaOH while being further stretched.

[Also in Group XL (a)] A heat-dissipating electrical shield for electronic components, e.g. discharge tubes, transistors, diodes or rectifiers, comprises a sleeve-like metallic envelope formed to closely embrace the electronic component in continuous, heatconducting contact therewith. The shield has heat-dissipating elements extending outwardly to augment its heat-dissipating surface area, and has a socket-engaging portion providing for low resistance thermal and electrical contact to an electronic chassis. As shown in Fig. 1, L- section members 2 and filler members 3 are secured at their lower ends by tubular member 50 and at their upper ends by a wire 6, looped through curled-over portions of members 2, 3, to form a substantially continuous metallic envelope surrounding valve 1. Loosening of the wire 6 permits easy removal of the valve. Alternatively, filler members 3 may be omitted and members 2 may be bonded to the valve envelope by means of an epoxy resin. The shield may also be in the form of a split cylinder provided with transverse fins. The shield shown in Fig. 6 consists of a helical coil of sheetmetal shaped to provide a fin 24, a portion 25 and a further portion underlying the portion 25 of the adjacent turn of the helix. The lower end of the shield is secured to a flanged ring 27 in contact with heat-sink 26. A removable cap 22 overlies the upper end of the shield. Unwinding of the helix permits removal of the valve.
