Title: Apparatus for blow molding of plastic articles
IPC: B29C49/28
Filed: 1968-01-17
Abstract: Extrusion-blow apparatus comprises at least one extruder, the nozzles of which are driven along an endless path, preferably circular, and a plurality of moulds adjacent the path. As shown in Figs. 1, 2, extruders 7, 71 having nozzles 32 are mounted on a turntable 1 rotatable in direction E, moulds 10 being supported on a platform 9 in a central orifice in the turntable. An electric motor 2 drives the turntable 1 by means of gear 5 meshing with teeth 8 on the internal edge of the turntable. By means of gears 12-15, it also drives a shaft 11 having a co-rotating sleeve 17 driven by longitudinal keys 16 and carrying platforms 18, 118 which support cam rings 19, 119 to operate mould unit 10 and mandrel unit 25 respectively. Mould halves are mounted on platens 24, 24a opened and closed by rack and pinion arrangement 33, 34, 33a via plates 22 and follower arm 21 displaced by cam 19. The mould units 10 and platform 9 may be vertically reciprocable by means of piston 30 of cylinder 31 to receive extrudate and retract out of the way of the continuous extrusion for blowing. Mandrel unit 25 having blowing nozzle 26 mounted on the assembly of mould unit 10, is horizontally reciprocable by means of rod 28 sliding in sleeve 27 by means of cam 119 and follower 121 and is vertically reciprocable by hydraulic cylinder 25 for blowing the extruded parison and withdrawal from the path of the extruders. In an alternative embodiment (Figs. 4, 5, not shown), mould units (61) are spaced around the rotating extruders (58) and the extruders may be pivotable about input shafts (57, Fig. 4) or rod (66, Fig. 5) and may be longitudinally extensible for use with different moulds.

Title: Process for the posttreatment of titanium dioxide pigment
IPC: C09C1/36
Filed: 1968-02-01
Abstract: TiO 2 pigment is coated with an oxide or hydrated oxide by separately introducing steam and one or more halides into a fluidized bed of the TiO 2 which is at a temperature of 100- 600 C. The halide may be AlCl 3 , TiCl 4 , or SiCl 4 . Air may be used to maintain the bed fluidized, and as a carrier for the steam and halide.

Title: Device for dosing of flocked material
IPC: B05C19/00
Filed: 1968-08-28
Abstract: Apparatus for applying flock to a surface comprises a hopper haying a bottom portion at least partially constructed as a sieve, and vibrator means operably associated with the hopper for initiating non-linear vibrating motion of the hopper, the latter defining a closed path for the flock. As shown, a hopper for distributing flock into an electrostatic field for deposition upon a moving web W comprises two straight portions 1, 3 arranged transverse to web W and interconnected by curved end portions 2, 4. The hopper is positioned above beams, 7, 7a by springs 3a, the lower ends of which are secured to the latter and the upper ends to the portions 1, 3. The springs associated with the respective portions 1, 3 incline in opposite directions. Each end portion 2, 4 is supported by three springs arranged at right angles to each other. Associated with each spring is an electromagnetic device 3b adapted, when energized, to impart longitudinal vibration and slight lateral vibration to the spring. The arrangement is such that the flock circulates in the hopper in the direction of the arrow. The bottom of each portion 1, 3 is in the form of a detachable sieve having a ribbed centre portion 8. The perforations in portion 3 may be larger than those in portion 1. The hopper may be divided by a partition into two separate channels containing different coloured flock, and the perforations in the channels may be staggered to provide a striped effect on web W. In a modification the hopper is suspended by springs from the beams. For coating single articles, a cylindrical hopper depends from a rigid plate suspended by springs associated with respective electromagnetic devices.

Title: Cigarette burn resistant mattresses having aluminized polyurethane foam layer
IPC: D06Q1/04
Filed: 1974-03-29
Abstract: This invention is concerned with flameproofed mattresses, pillows and sleeping bags, pads, cushions for chair or sofas, and so on. The flameproofed materials of the present invention may be formed of (1) a close-woven fabric attached to (2) a thick layer (e.g., 0.1-1 inch) of resilient self-extinguishing polyruethane cushioning foam having (3) a metallized heat-conductive layer, such as of aluminum, which dissipates heat rapidly, thereupon, the metallized foam being secured to (4) filling or padding with (5) a backing fabric secured thereto. The parts are suitably locally secured together by tying means such as stitching, tufting, dielectric welding or the like. The object is to protect the main body of highly combustible filler material in cushions, pillows, mattresses, sofas, upholstered chairs, and the like from fire in case of the dropping of a match, cigarette, or the like on the cover fabric or ticking by someone, such as a careless smoker. Even though the foam is self-extinguishing relative to a lighted cigarette, when not compressed, when it is compressed by tying as by stitching, the heat may be conducted therethrough and ignite the filling or stuffing, if no metal layer is present.

Title: Apparatus for loading fuel pellets in fuel rods
IPC: G21C21/02
Filed: 1975-01-03
Abstract: Apparatus for loading fuel pellets into fuel rods for a nuclear reactor including a base supporting a table having grooves therein for holding a multiplicity of pellets. Multiple fuel rods are placed in alignment with grooves in the pellet table and a guide member channels pellets from the table into the corresponding fuel rods. To effect movement of pellets inside the fuel rods without jamming, a number of electromechanical devices mounted on the base have arms connected to the lower surface of the fuel rod table which cyclically imparts a reciprocating arc motion to the table for moving the fuel pellets longitudinally of and inside the fuel rods. These electromechanical devices include a solenoid having a plunger therein connected to a leaf-type spring, the arrangement being such that upon energization of the solenoid coil, the leaf spring moves the fuel rod table rearwardly and downwardly, and upon deenergization of the coil, the spring imparts an upward-forward movement to the table which results in physical displacement of fuel pellets in the fuel rods clamped to the table surface.

Title: Installation for inspecting and sorting printed sheets of paper
IPC: G07D7/00
Filed: 1980-05-30
Abstract: The installation comprises several inspecting devices disposed along a track and controlling a switch. Each inspecting device is followed by a device for detecting the passage of the sheets, associated with a cyclic counter assigning a consecutive number to each sheet. A logic circuit directs the information from the inspection devices to reference memories the number of which is equal to the number of possible content conditions of the counters, (i.e. consecutive numbers) the information being directed to the reference memory whereof the number corresponds to the consecutive number of the sheet as assigned by the counters. Since the sheets are assigned numbers during their passage through the inspection region, it is possible to have several sheets simultaneously in this region.
