Title: Fecal examination device and a method for the use thereof in the examination of fecal matter
IPC: G01N33/483
Filed: 1975-11-03
Abstract: A chamber for a flotation process has a bottom (2) and an open top end (3). Around the top peripheral edge is arranged a closure (4) for engaging in a standardised transport container. The lower side wall of the chamber is provided with many holes (5), so that a screening device is formed, the dimension of which is several times larger than that of the parasite eggs. The bottom side of the closure has a truncated cone shape (9), the apex of the cone being formed at the top, the closure being joined in a liquid-tight manner to the outside of the chamber. The openings, situated on the outside, of one row (10) of holes are arranged directly beneath the junction point. The excrements are diluted in the transport container with a liquid which also forms a liquid level in the chamber which is higher than that in the transport container. The density of the dilution fluid is between that of the parasite eggs and that of the excrements. The eggs ascend and pass through the row of holes (10) into the chamber. <IMAGE>

[Also in Division D1] Melamine derivatives modified by fatty acid groups are prepared by heating a fatty acid methylol amide, derived from a fatty acid having >10 C atoms, the methylol groups of which have been etherified by monovalent saturated C 1 -C 6  aliphatic alcohols, with highly etherified methylol melamine; the latter contains at least 3 methylol groups per molecule which have been etherified by a C 1 -C 6  saturated aliphatic alcohol. The etherified methylol melamine may be formed in situ by reacting together, the etherified fatty acid melhylol amide, melamine, paraformaldehyde and a monohydric saturated C 1 -C 6  aliphatic alcohol. A considerable excess of formaldehyde and alcohol may be present initially which is subsequently removed by distillation when reaction is complete. Suitable fatty acids exemplified are stearic, lauric and undecylenic acids. From 0À3 to 1 mole of etherified fatty acid methylol amide may be used per mole of highly etherified methylol melamine.

Abstract: 1,144,413. Friction clutches; securing together rotary parts. DR. HERMANN E. MULLER. 10 Oct., 1967 [12 Oct., 1966], No. 46237/67. Headings F2C and F2U. In a friction clutch, a presser plate 3, urged by a clutch spring 4 to clamp a driven disc 5 against a driving flywheel 1, is centred and rendered rotatable with, whilst being axially movable with respect to, a clutch cover 2 fast with the flywheel by opposed circumferentially acting prestressed springs bridging gaps between presser plate projections 8 and edges of cover apertures 9 through which said projections extend, said springs engaging the cover and radial side faces 10 of the projections and, to avoid sliding friction, partaking in the axial movements of the projections. Relative rotation of the presser plate and the cover is so limited by the extent of projection/aperture clearance as to prevent excessive spring deformation. As shown, longitudinally split tubular springs 11 disposed radially of the clutch are clipped into cover grooves 12 and roll on the projection side faces 10. The springs may be of elliptical or, as shown, substantially circular cross-section. In Fig. 5 (not shown), re-entrant portions of split tubular springs are clipped over the cover aperture edges and the split edges engage shoulders or grooves in the projection side faces. In Fig. 6 (not shown), opposed pairs of leaf springs riveted to the cover have arcuate portions bearing on flat or recessed projection side faces. In Fig. 7 (not shown), opposed pairs or single leaf springs riveted to the cover have edges engaging shoulders or grooves in the projection side faces. Clutch release levers 6 fulcrumed on the cover 2 are connected to the presser plate by links 7. Each link 7 comprises male and female, or, as shown, female and male screw-threaded portions respectively pivoted to the presser plate and having a cruciform end constituted by four trunnions (20), one pair of which engages grooves in a forked release lever end. Release lever adjustment is by rotation of the trunnioned portions through 90 degrees steps.

Abstract: 1481759 Dewaxing oils EDELEANU GmbH 11 Nov 1975 [26 Nov 1974] 46562/75 Heading C5E In a process for dewaxing a mineral oil in the presence of a solvent which is recycled, a portion of the solvent is recovered from the dewaxed oil and from the wax by steam stripping and the mineral oil feed and the moist steamstripped portion of the solvent are dried in admixture by azeotropic distillation prior to entering the dewaxing stage. The dewaxing can be achieved either by cooling to precipitate wax or by the formation of adducts with urea. The major portions (up to 95%) of the solvent in the dewaxed oil stream 1 and in the separated wax stream 2 are removed in indirectly heated evaporator columns 3 and 4 and 9 and 10 respectively. The solvent-depleted streams are then stripped with steam in columns 12 and 13 and the steam-laden solvent residues are combined and condensed at 17 to produce aqueous and solvent phases in the separator 19. The moist solvent phase 26 is dried at 27 together with the oil feed 27 by azeotropic distillation. The overhead 32 comprising solvent and water is condensed at 33 and the dried solvent and oil stream 29 is passed, together with a portion 35 of the dry solvent from collector 8 to the dewaxing stage. The aqueous phase 20 from the separator 19 is freed from solvent at 21 by injection of steam and discharged at 22.

Abstract: 1,073,372. Transistor pulse shaping circuits. ENGLISH ELECTRIC CO. Ltd. Dec. 11, 1963 [Dec. 11, 1962], No. 46805/62: Heading H3T. The secondary winding of a transformer connected between base and emitter of a transistor is series resonated by a capacitor and input pulse which are applied to the primary winding to cause the transistor to saturate have a duration slightly longer than a quarter of a cycle of the oscillation period of the circuit. In this way the output pulse may be less dependent on input pulse width. In Fig. 1 input pulses are applied via a terminal 11 to cut off a transistor 14 which is normally maintained just short of saturation by a feedback bias circuit 24. The leading edge of the resulting pulses start oscillation in a series tuned circuit 30, 31 causing transistor 25 to switch on and saturate. After a quarter of a cycle the current reverses withdrawing stored charges from the base and (at point, Fig. 2, not shown) the combined effect of this and the trailing edge of the input pulse causes transistor to be switched off. An output pulse is derived from the emitter and the positive excursion at this point is limited by a diode 34. In an alternative circuit (Fig. 3, not shown) a common base amplifier (36) is inserted between the two stages and an output pulse winding is added to the tuned transformer or to the output stage to supply another similar pulse shaper stage.

Abstract: 1398808 Ion implantation of gallium arsenide HUGHES AIRCRAFT CO 8 Oct 1973 [6 Nov 1972] 46877/73 Heading H1K Electrical isolation barriers are formed in GaAs by accelerating neon or heavier ions at 20 KeV or less into selected regions at 200- 500 C. The ions raise the resistivity of the regions to 10<SP>7</SP> ohm. cm. or higher and this figure is not lowered by annealing below 800 C. The ions are exemplified by Ne, Ar, Kr, Xe, Cd, Zn, S, Se and Te. If Cd or Zn is used a thin P-type layer is formed on the surface while S, Se or Te produces an N-type layer; these layers are preferably removed. In an embodiment an N- type semi-insulating GaAs substrate has an epitaxial N+ -type GaAs layer formed thereon by reaction of Ga with AsCl 3 . A scanning or masked beam of heavy ions is used to form frames of semi-insulating isolation barriers while heating to 200 to 500 C. Devices, e.g. a transistor and a resistor (Fig. 3, not shown) are formed in the isolated pockets by ion-implantation. In another embodiment the epitaxial layer is first provided with four Schottky barriers of aluminium and the barriers are used as masks for subsequent implantation with heavy ions (Figs. 4a and 4b, not shown). A plurality of photodetectors may be made on a common substrate.
