Title: Slewing ring with pinion drive - grease lubricated totally enclosed, can be operated on slope
IPC: E02F9/12
Filed: 1974-06-20
Abstract: The slewing ring on an earthworking machine is fitted with internal teeth (4a) and roller bearings (18). The pinion (8) meshes with the slewing ring supported in the bearing (10), and surrounded by baffle plates which contain the lubricant around the pinion. The ring is filled with a thin grease lubricant (14) which normally fills the space up to the pinion. An inner seal (17) and an outer seal (18) prevent grease from leaking out. When the slewing ring is on a slope, the grease will rise slowly on the lower side to the space (16). Its viscosity will ensure that the pinion is always well lubricated.

Title: Straightening or heat treating long thin parts - using induction heating coil and tensile stress producing plastic deformation
Inventor: BOURNICON CLAUDE
IPC: B21D3/12
Filed: 1974-10-25
Abstract: Treatment of long thin components to improve their internal structure, or for straightening, involves the successive heating of at least certain zones of the component and submitting the zones to a controlled value of elongation so that plastic deformation occurs. The elongation is pref. obtd. by controlled stretching of the component which is pref. rotated during the treatment. The pref. machine uses an induction heating coil mounted on a trolley which also carries a coolant spray for cooling the heated zone after deformation, and the trolley travels upwards on guides so the inductor can travel along the component which is subjected to tensile stress. Process is suitable for metals, alloys or plastics, e.g. foils for swordplay, rapiers, sabres, lances and also for long drill holders used in mining, the petroleum industry etc.

Title: Sorting and orientating of small articles - has random discharge onto rotating rim with partially covered radial channels
IPC: B65D1/09
Filed: 1975-08-14
Abstract: The articles are randomly discharged upon a rotating radially aligned channel, and a vertical restraint is imposed upon the articles within the channel, so as to align the articles with respect to the channel. The articles are dropped while rotating, such that the desired orientation is achieved within and prior to discharge from the channel. Orientation occurs as the parts are distributed circumferentially and radially, that is the parts are arranged in moving single file lines. The articles may be selectively discharged from the apparatus and they may be counted as they are discharged. A high speed, low revolution per minute counting system is obtained by storing the articles in batches.

Title: Forming homogeneously orientated liq. crystal films - by applying to the confining substrate an orienting surfactant e.g. a polyvinyl alcohol deriv.
IPC: G02F1/1337
Filed: 1976-02-10
Abstract: A homogeneously orientated film of a nematic liq. crystal (I), confined between 2 plates, is formed by the influence on the molecules of (I), of an orientating matrix applied to the surface of the plates. The matrix consists of 1 monomolecular layer of surfactant (II) which, before application to the plaes, is formed at a liq. -gas phase boundary and after application, is thermally treated at 80-180 degrees C. (II) are esp. of formula RX(CH2)1Y (IIa) or are polyvinyl alcohol derivs. of formula:-(choh.ch2)n'- (CH2OX'.CH2)m' (IIb) (R = CnH(2n+2k-m)Zm. n = 12-37. 0 m 2n. -3 k 1.Z = F, Cl or Br. X = CH2, CO, O, S, CH=CH, or > C=CH2. 1 = 0-5. Y = OH, COOH, COOCH=CH2, OCO.CH=CH2, OCO.C(CH3)=CH2 or, provided n 18, also SO3H, PO3H2 or Si(OCH3)3. 20 m' n' = 20-10000. X' = COCH3, COCF3, benzoyl, cinnamoyl, CH3, C2H5, allyl, 2,3-epoxypropyl). Both homotropic (using (IIa)) or homogeneous (using (IIb)) orientations can be achieved over a wide temp. range which improves the characteristic voltage-contrast curve of teh cell and reduces its relaxation time. The matrix tends to 'smooth out' any irregularities in the surface of the plates.

Title: Mixer-decanter for liquid-liquid extraction - with transfer pump and channel inducing min. turbulence, allowing pre-coalescence, giving economical construction
Inventor: MEYER MAURICE
IPC: F01D1/14
Filed: 1976-03-11
Abstract: The mixer is a vessel fed separately with the two liquids and having an agitator on a vertical shaft. Above the agitator is a pump with a conical stator, widened at the top, and a rotor with trapezoidal blades. The rotor is fixed on to the same shaft as the agitator. The predetermined mixt. leaving the pump flows through a long wide, shallow horizontal channel. It extends to the end of the decanter remote from the mixer, so that the liq. circulates in the decanter towards the mixer. A distributor, formed by horizontal parallel blades extends over the height and width between the place where the channel discharges and the rest of the decanter. There may be a battery of mixer-decanter units, in series, with the two liquids circulating counter-currently. The battery may be used e.g. to purify an aq. soln. of a metal ion by an organic phase e.g. kerosene in which is dissolved an ion-exchanger specific to the ion being extracted, with a re-extraction battery fed with aq. NaCl soln. and the organic phase from the extraction battery. The plant occupies less space than existing plants of the same type, and requires considerably less piping and auxiliaries.

Title: Refining PVC and preparing it for extrusion - comprises heating and degasifying the powder under vacuum after adding solids
IPC: B29B9/00
Filed: 1976-04-15
Abstract: Polyvinylchloride is refined during heat treatment and esp. whilst additives are being mixed in. The powder form PVC is agglomerated and extruded, by raising its temp. first to a point below its plasticising temp. and removing whilst maintaining this, residues of vinylchloride monomer gases, and only then progressing it without any intermediate cooling, for further processing, esp. at a higher temp. Residual vinylchloride monomer is removed as far as possible before agglomeration and envelopment by the additives can take place. Water is also evacuated simultaneously, so that there is no need for measures to remove condensate from the mixers.

Title: Fibrous material used in making papers and cartons - prepd. from expanded polystyrene
Inventor: VALLETTE PIERRE
IPC: D21H21/52
Filed: 1976-07-15

The chain consits of a succession of segments also arranged at random in three dimensions, each membrane being attached to at least one segment. The material is partic. useful in the mfr. of embossed papers and of paers and cartons which can be heat-formed. The material is easily incorporated in the paper and in certain cases aids the mfg. process, partic. in the drying stage. Its retention in the paper is high and it can improve the properties of the paper, e.g. its opacity.

Title: Pyrolysis of organic wastes - using mineral particles obtained from the pyrolysis residue as heat source
IPC: C10B53/00
Filed: 1976-08-11
Abstract: The pyrolysis of mineral-contg. solid organic waste materials is carried out by (a) comminuting the material to a particle size of 25 mm (4 mm, esp. 2.38mm) and drying it; (b) mixing the material with a non-reactive carrier gas and hot mineral particles (see below); (c) passing the mixt. under turbulent flow conditions through a pyrolysis zone maintained at a temp. above 315 degrees C but below the fitting temp. of the mineral particles (pref. 315-925 degrees C, esp. 425-760 degrees C) to form a carbon-contg. residue, condensable oils and gases; (d) separating the residue (mixed with mineral particles); and (e) decarbonising at least part of the residue to form additional mineral particles at a temp. below their m. pt. The process can be used to treat a wide range of industrial wastes and/or domestic refuse from which large-sized useful components (metals, paper, etc.), have been removed. The decarbonised mineral particles are superior to the C-contg. residue as a heat source since they have better wear resistance, a higher apparent density and better fluidising properties.
