[Also in Division C5] An oleophilic graphite, that is a graphite obtained by grinding under the surface of an organic liquid until the graphite has a surface area of at least 20 m.<SP>2</SP>/gm., has adsorbed on to its surface a substantially straight chain polymer that is a polymer having a major proportion of its backbone composed of carbon atoms the carbon atoms in the backbone being unsubstituted or substituted by one methyl substituent. Preferably no substituent groups are present. Preferred polymers are polyethylene, polypropylene, or a copolymer thereof and the graphite contains less than 5% by weight of the polymer. The polymer may have a molecular weight of at least 10,000. The modified graphite may be prepared by grinding natural or synthetic graphite below the surface of an organic liquid, as indicated above and before, during or after the grinding adding a straight chain polymer to the liquid. This liquid may have a viscosity below 600 centistokes at 100‹ F. (38‹ C.), distil below 500‹ C. and have a surface tension below 72 dynes/cm. at 25‹ C. It is preferably a hydrocarbon having from 1 to 10 carbon atoms.

A drive for a press &c. work feeder 37 driven by a rotating shaft S to have reciprocatory movements separated by periods when the feeder is static or relatively slow moving, comprises two slides 10, 15 guided for reciprocatory movement parallel to the feed direction and one of which (10) is driven by a crank 1, a coupling 12, 16, 19 interconnecting the slides for synchronous movement, and a guide cam 22 acting on the coupling to allow relative movement between the slides when the driving slide 10 is near the ends of its strokes, the driven slide 15 driving the feeder. A work-gripper (not shown), or a plurality of grippers for stepwise transfer, are provided on the feeder carrier 37 which is movable transversely of the driven slide 15 at the ends of the strokes to pick-up and set down workpieees. Guide-rods 39 on the carrier 37 slide in bearings 41 in the driven slide. A crank 1 on the drive shaft is connected by a rod 2 to a link 3 which reciprocates the drive slide 10 through a rod 8. A lever 12, 16 on a pivot 17 on the slide 10 has one end connected by a link 19 to the driven slide 15 and the other supporting a roller 21 running in the guide cam 22. This has a straight intermediate section with deflected ends which produce relative movement between the slides towards the ends of the strokes of slide 10, thus allowing the driven slide 15 to stop or move slowly before the drive slide 10 reaches the ends of its stroke. The relative movement is used to lower and raise the carrier by means of a rack 28 on the slide 10 engaging a pinion 29 driving a crank-shaft 30 on the slide 15. Attached to the crank-shaft is a connecting rod (32), Fig. 2 (not shown), coupled by a resilient link (35) to the carrier 37 so as to permit further movement of the crankshaft 30 after the carrier has been arrested by adjustable stop-screws 40. Rollers 11 guide slide 10 in slide 15, and the ends of the guide cam may be arranged to uncouple the slides.

[Also in Divisions B7 and F2] A pneumatic flotation conveyer comprises, Fig. 5, a plenum chamber 70 formed between parallel top and bottom plates 72 and 74 and parallel side pieces 76 and 78, gases supplied to the plenum chamber 70 through pipe 92 discharging through holes 90 in plate 72 so as to inflate portions of a flexible membrane 82 bonded or otherwise attached to the top plate 72 along circles 84. The membrane has circular apertures 86 centred on corresponding holes 90, the diameter of apertures 86 being less than that of the bonding circles 84 so that the gases escaping through holes 90 bow the free edges of the membrane apertures away from plate 72 and the bowed membrane portions thus contain gas cushions which are used to support a load bearing platform 80 which is movable above the membrane between guides formed by the plenum chamber side pieces 76 and 78. Small apertures 88 may be provided around apertures 86, helping to eliminate flutter of the free edges of the membrane. The apparatus may be used with the membrane attached to the load platform 80, air from holes 90 inflating the membrane away from the lower surface of the platform. Fig. 8. The membrane may also be incorporated into a hollow plenum chamber type floor, for example in an aircraft, and used to support a load on the floor, Fig. 4 (not shown).
