Abstract: 1326289 Portable containers; packages ETABS DENTAIRE IVOCLAR 19 April 1971 [27 Feb 1970] 24335/71 Headings B8C and B8D [Also in Division F1] Receptacle main and secondary chambers M and S respectively holding constituents 5 and 6, which are not to be mixed until use, such as resins or dental amalgams, are separated by a resilient dividing wall 33 having one or more transverse weakening grooves 4 along which the wall ruptures on lateral squeezing of the side walls 51 of the receptacle so as to form a selfclosing opening between the chambers. The formed opening recloses on release of lateral pressure on the side walls due to the resilience of the dividing wall, which, together with the receptacle walls, may be of plastics, metal/ plastics laminate, or sheet metal. When of sheet metal, the groove may be replaced by a slit, which is covered by a rupturable metal foil. As shown, the main chamber is formed in a syringe-like tubular bo dy, and the secondary chamber is formed in a hollow piston-like body 32 located in the tubular body and closed by a welded foil cover 37. After rupturing of the dividing wall and mixing of the constituents in the main chamber, the mixture is dispersed through a nozzle 56, 57 by forcing the body 32 downwards using a ram 52 with or without removing the cover 37. Inadvertent displacement of the piston body in the tubular body is prevented by a lip 39 on the former or a rib on the latter. The nozzle end is sealed by a frangible membrane 55, by plugs 48 or 58 or an integral cut-away tip, Figs. 4 and 5a and 5b (not shown). In another embodiment, Fig. 3 (not shown), the tubular body 31 is closed at its open lower end by a removable cover 38. In the embodiment of Fig. 6 (not shown), a sealed catalyst-containing pouch 63 is located between an end cap 64 and an apertured insert 61 and is adapted to be ruptured on depression of the cap so that its contents are dispensed into the main chamber to mix with monomer and polymer constituents 5 and 6. In a further modification, Fig. 2 (not shown) the hollow body 22 is located in the upper end of a cup-shaped body 21 on a rib 29 and is removed to dispense the mixed constituents from the main chamber. In a final embodiment, Fig. 1 (not shown), the dividing wall is integral with the tubular body 1, which is closed at one end by an integral or welded plastics cover 7 and at the other end by a removable cap 8.

Class 64(2) [Also in Groups XVII and XXXVII] A temperature-sensing capillary tube 5 and a Bourdon tube 1 are filled (apart from a little irremovable residual gas) with methyl alcohol or monochlorodifluoromethane, 90-99.9 per cent of which is liquid 10 whilst the remainder forms a vapour bubble 6 so that the bubble transfers itself to any hot spot 9 which may occur and the variation in vapour pressure due to temperature change at that spot is transmitted by the liquid 10 to the Bourdon tube. The tube 5 is long and flexible and may be threaded about in contact with critical points of an apparatus, Fig. 6, not shown, so that overheating of any of the points causes the Bourdon tube 1 to shut down the apparatus, e.g. by an electric switch. Communication with the Bourdon tube is through a bore in a fixed block 2 and the tube 5 may be of glass or stainless steel. The system and filling liquid are degassed before the system is filled. For filling, the system is immersed in a liquid bath, Fig. 5, not shown, at a temperature above the operating range of temperature and the air pumped out. The filling liquid is then introduced under a pressure above that of its vapour pressure at the temperature of the liquid bath. The pumping may be repeated and further liquid added. On sealing and cooling, the vapour bubble 6 forms.

Abstract: 318,149. Palmaer, K. W. Aug. 28, 1928,.date]. Metals of the iron group, depositing; aluminium salt solutions, purifying; liquid-electrode apparatus. - Metals of the iron group, e.g. iron and nickel, are removed from solutions containing them by electrolysis, using an agitated or flowing mercury cathode, the current density and movement of the mercury being so regulated that the deposited metal dissolves in the mercury without formation of a film. The mercury preferably flows along a vertical or inclined surface. Ferric salts are preferably reduced to ferrous and the solution neutralized as far as possible before electrolysis. In an example an aluminium sulphate solution containing 100 gms. alumina and 3.45 gms. iron (mainly bivalent) per litre is neutralized by the addition of 100 gms. calcium carbonate per litre, and electrolyzed with a flowing mercury cathode at a current density of 3 amps. sq. dcm. A lead anode surrounded by a diaphragm may be employed. When treating aluminium chloride solution an anode of coal is employed. The deposited metal may be removed from the mercury continuously or intermittently, e.g. by treatment with mercurous nitrate solution.

Filed: 1967-01-11
Abstract: 1,171,541. Dynamo-electric machines. NATIONAL RESEARCH DEVELOPMENT CORP. 30 Nov., 1967 [11 Jan., 1967; 30 May, 1967], Nos. 1406/67 and 24764/67. Heading H2A. An electrical generator has a rotor which co-operates with first and second conductors connected together through current control means and positioned so that a voltage induced in the first conductor will cause a current flow in the second conductor to aid magnetization of the rotor, but voltage induced in the second conductor is prevented from causing current flow in a demagnetizing direction in the first conductor by the action of the current control means. As shown in Fig. 2a, conductors 11, II<SP>1</SP> have an E.M.F. induced in them on rotation of rotor 10 and a current will flow in quadrature conductors 14, 14<SP>1</SP> to provide a magnetic field aiding that of the rotor which may be permanently magnetized. Similarly, a current will flow in conductors 19, 19<SP>1</SP> when a voltage is induced in conductors 18, 18<SP>1</SP>. When the rotor has turned through 90 degrees a voltage will be induced in conductors 14, 14<SP>1</SP> which is prevented from causing current flow in a demagnetizing direction in conductors 11, 11<SP>1</SP> by the blocking action of rectifiers 16 and capacitors 17. A plurality of coils can be used around the stator and a normal output winding provided around the stator core (not shown). In alternative arrangements the unidirectional control of current can be provided by amplifiers or by mating one of the quadrature conductors to include magneto-resistive material. In a different embodiment using a gyrator circuit or a Hall plate as the current control means current reversal so that the flow of current in the inphase conductors will aid the magnetization of the rotor when the quadrature conductors have voltages induced in them, Figs. 5 and 6 (not shown). The rotor may consist of a salient pole portion and a cylindrical portion with an induced coil surrounding the salient pole portion and connected through the current control means to coils surrounding the whole length of the rotor. The output winding being associated only with the cylindrical portion of the rotor. In a practical construction, Fig. 7, two U- shaped stator parts with poles 30, 30<SP>1</SP> and 32, 32<SP>1</SP> and yokes 31, 33, are assembled together. Conductors 35 in stator 30 are connected through a unidirectional control to coils 36, 37 wound on yoke 33 with a similar arrangement of conductors and coils provided on the other stator. Alternatively, a laminated stator may be provided where the laminµ are of identical shape but angularly displaced by 90 degrees electrical, Fig. 8 (not shown).
