Abstract: ABSTRACT OF THE DISCLOSURE       A fuel pumping apparatus includes an annular cam having lobes which urge a pumping plunger in an inward direction through a roller during an injection stroke.          A feed pump supplies fuel by way of a throttle  to a bore containing the plunger during a filling stroke and a pair of ring members limit the outward movement of the roller and thereby control the maximum fuel.  The ring members can be moved axially away from each other to allow an extra amount of fuel to be supplied for starting purposes.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention provides partially pyrolyzed particles of a macroporous synthetic polymer having properties suitable for use in adsorption, molecular screening and/or catalysis and a resistance to crushing and particle sloughage greater than that of known spherical adsorbent particles or that of granular activated carbon, comprising the product of controlled thermal degradation of a macroporous synthetic polymer containing a carbon-fixing moiety and derived from one or more ethylenically unsaturated monomers, or from monomers which may be condensed to yield macroporous polymers, or mixtures thereof, which partically pyrolyzed particles have: (a) at least 85% by weight of carbon, (b) multimodal pore distribution with macropores ranging in size from about 50 .ANG. to about 100,000 .ANG. in average critical dimension and with macropores ranging in size from about 4 .ANG. to about 50 .ANG. in average critical dimension, and (c) a carbon to hydrogen atom ratio of between about 1.5:1 and about 20:1.  A process for producing the aforesaid partically pyrolyzed particles is also described.          This process comprises thermally degrading at a temperature between about 300°C and about 900°C, preferably between about 400°C and 800°C, and in an inert gaseous atmosphere optionally containing an activating gas, a macroporous synthetic polymer containing a carbon-fixing moiety and derived from one or more ethylenically unsaturated monomers or monomers which may be condensed to yield macroporous polymers, or mixtures thereof, for a time sufficient to  drive off sufficient volatile components of the synthetic polymer to yield particles having the characteristics described above; and thereafter cooling said particles under said inert atmosphere to a temp-erature below that which would cause oxidation in air.  The pyrolyzed particles so produced are particularly useful as adsorbents in both gaseous and liquid media to remove impurities therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE             Compacted pallets of uranium oxide of uranium oxide with one or more additives are heated in a kiln in a process having a preheating step, a sintering step, a reduction step, and a cooling step in a controlled at-mosphere.  The process is practiced to give a range of temperature and atmosphere conditions for obtaining optimum fluoride removal from the compacted pellets along with optimum sintering in a single process.  The preheating step of this process is conducted in a tem-perature range of about 600 to about 900°C and the pellets are held for at least twenty minutes, and preferably about 60 minutes, in an atmosphere having a composition in the range of about 10 to about 75 percent hydrogen by volume with the balance being carbon dioxide. The sintering step is conducted at the temperature in the range of about 900°C to 1500°C in the presence if an atmosphere having a composition in the range of about 0.5 to about 90 present hydrogen by volume with the balance being carbon dioxide.  The reduction step reduces the hydrogen to metal ratio of the pellets to a range of about 1.98 to 2.10:1 and this is accomplished by gradually cooling the pellets for about 30 to about 120 minutes from the temperature of the sintering step to about 1100°C in an atmosphere of about 10 percent to about 90 percent hydrogen by volume with the balance being carbon dioxide.  Thereafter the pellets are cooled to about 100°C under a protective atmosphere and in one preferred practice the same atmosphere used in the reduction step is used in the cooling step.  The preheating, sintering and reduction steps may also be conducted with their respective atmosphere having an initial additional component of water vapor and the water vapor can comprise up to about 20 percent by volume.

Abstract: ABSTRACT OF THE DISCLOSURE         The gascleaning apparatus for a blast furnace operating under pressure using a differential-pressure washing arrangement whereby the differential-pressure washer comprises at  least one annular gap with an annular-gap passage and an axially adjustable body received in the annular gap washer. The nozzle is disposed upstream of-the annular-gap washer to spray the washing liquid into the gas which is accelerated through the annular gap.  The position of this body is controlled in response to the gas pressure within the head of the blast furnace. The annular gap of the washer diverges in the direction of flow of the gas and the body has a complementary shape so that the gap width remains generally constant although its flow  cross section increases with the diameter of the annular gap in the direction of flow of the gas.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for joining crinoline to drapery material to provide a stiffening for pleats.     The method consists of laying the drapery material face down on a table where it is secured by clamping devices at opposite ends so as to maintain the material in a stationary position.     The joining apparatus is activated to move across the edge of the drapery material which is to undergo the crinoline-bonding step.  A feed roll dispenses a crinoline strip and, simultaneously, a second feed roll dispenses an adhesive filament which is interfed between the said crinoline and said drapery material.  A preheater directs warm air over the crinoline immediately prior to its emplacement upon the material, whereupon, a heat wheel follows to apply heat and pressure to the combined layers of material, tape and crinoline so as to liquify the adhesive and cause it to spread so that it joins the crinoline and the material in a permanent bond.     Also, in addition to preheating the crinoline, the material is preheated to afford a more rapid and effective seal.     A cutter and cutter guide follow the heat wheel in a slotted track whereupon the excess of joined material and crinoline are cut off to provide a proper finish.
